Abstract
The operating mechanism comprises a mounting base which consist an
operating rod assembly, a turntable assembly and an energy storage
element. Under normal circumstance, the operating rod assembly
links to the handle and the switching-on or switching-off can be
realized through the rotation of the turntable assembly driven by
the energy storage element after rotating the handle. Under the
condition that a contact is fusion welding, the turntable assembly
is kept at the switching-on position and cannot rotate. The turntable
assembly abuts against the promotion part, The operating rod
assembly is prevented from rotating to the switching-off position
by the blocking part, This caused the rotating handle shows is not
switching-off. Therefore, an operator can easily find the fusion
welding condition, The potential safety hazards are reduced.

[0001] The present invention relates to a rotary switch, and in
particular, to an operating mechanism for rotary switch.
[0002] The rotary switch is isolating switch. When at switching-off
position, the insulation distance between the moving and static
contact shall meet the specified requirements, and the switch shall
have an obvious disconnection mark. When at the switching-on position,
the contact shall be capable of carrying the current under normal
circuit conditions or the current under abnormal conditions within
a specified time. When the electrician is required operated, they
need to cut off the power and padlock when necessary to prevent
accidental operation by others and to ensure the safety of operator.
However, Under the condition that the moving and static contact are
melted welding, the power may fail to be cut off only by the rotary
switch. If the moving and static contact fail to work to cut off the
current while the twist grip shows switching-off or even show
padlocked, the operator may continue the operation for they think
the current has been successfully cut off, which makes the electric
shock extremely easily occur. The national standard on the operating
mechanism for rotary switch requires that: when the contacts are
melted and welded when at switching-on position, the operating force
for rotating the switch handle to switching-off should be at least
triple the operating force (and no less than 100N) under normal
conditions. Existing operating mechanism satisfies the standard through a design with torsional spring. The operator may be aware of the abnormal situation through feeling different operating force.
However, this is not entirely reliable. Failure to feel the different
operating force due to unfamiliar operation or operator's being more
of strength results in the potential hazards.
[0003] The present invention aims at overcoming the defects of
existing technology and providing an operating mechanism for rotary
switch.
[0004] The technical proposal adopted by the present invention is
as follows: an operating mechanism for rotary switch comprises an
mounting base; an operating rod assembly used for manual rotation
and a turntable assembly are arranged in the claimed mounting base;
an energy storage element is arranged between the claimed operating
rod assembly and turntable assembly. The turntable assembly realizes
switching-on or switching-off of the switch through forward rotation
or reverse rotation. The operating rod assembly rotates to enable
the energy storage element to drive the turntable assembly to rotate.
Astopblock is hingedinto the mountingbase and comprises apromotion
part and a blocking part. The turntable assembly and the promotion
part work together so that the stop block can rotate to the first
position and the second position relative to the mounting base: when
the turntable assembly is located at the switching-on position, the
turntable assembly reaches the promotion part so that the stop block
is at the first position , and thereby the blocking part is located
on the rotating path of the operating rod assembly or the energy
storage element to block and limit the rotation of the operating rod
assembly. When the turntable assembly is located at the switching-off position, the turntable assemblyis separated from the promotionpart, the stop block is located at the second position, the blocking and limiting effect on the rotation of the operating rod assembly from the blocking part is removed.
[0005] The first reset elastic piece is arranged on the claimed stop
block to make the stop block locate at the second position.
[0006] The first limit post is affixed on the promotion part of the
claimedstopblock. The claimed first resetelasticpiece is apressure
spring held by the first limit post. The claimed mounting base is
disposed by a spring limit slot.
[0007] The first smooth surface is designed at the side wall of the
claimed promotion part matching the turntable assembly.
[0008] The claimed operating rod assembly comprises an operating rod
and a cam arranged around the operating rod and in the circumferential
direction linkedwith the claimedoperatingrod; the claimed turntable
assembly comprises a turntable and a slidingblock set on the turntable
and slides radially relative to the claimed turntable; in the claimed
mounting base two sliding block slots are arranged corresponding to
the switching-on and switching-off positions of the turntable
assembly; the second reset elastic piece which can make the sliding
block insert into the sliding block slot is arranged between the
claimed turntable and the sliding block; when the claimed sliding
block inserts into the slot, the claimed turntable assembly is not
rotatable and when the claimed sliding block leaves the slot, the
claimed turntable assembly is rotatable; the claimed sliding block
is arranged under the cam and there is a push plate arranged for the
claimed cam. The claimed cam rotates so that the push plate removes the sliding block from the sliding block slot.
[0009] The claimed turntable raises up with a side plate, and the
second spring limit post is designed in the inner side of the claimed
side plate; the push plate is provided with a first through hole
through which the second spring limit post passes and matches. The
claimed second reset elasticpiece is a pressure spring and is sleeved
on the second spring limit post. The two ends of the second reset
elastic piece respectively abut against the side plate and the push
plate.
[0010] The claimed mounting base is equipped with the first limit
baffle and the second limit baffle matching the claimed side plate,
the claimed side plate rotates between the first limit baffle and
the second limit baffle.
[0011] The claimed energy storage element is a disk torsional spring
with two flexible manipulators, the claimed cam upwardly convex with
the first spring roof, the claimed sliding block upwardly convex with
the second spring roof, the first spring roof and the second spring
roof are of the same width, the two flexible manipulators rely on
the first spring roof and the second spring roof on their two sides
respectively.
[0012] The claimed turntable is provided with a square bump, and the
claimed sliding block is provided with a square sliding groove
matching with the sliding of the square bump.
[0013] The square bump is provided with a circular through hole, and
the bottom of the operating rod inserts into a circular through the
hole.
[0014] The advantageous effect of the present invention is as follows:
under normal circumstance, the operating rod assembly links to the
handle and the switching-on or switching-off can be realized through
the rotation of the turntable assembly driven by the energy storage
element after rotating the handle. Under the condition that a contact
is melted welding, the turntable assembly is kept at the switching-on
position and cannot rotate. The turntable assembly abuts against the
promotion part. The operating rod assembly is prevented from rotating
to the switching-off position through the blocking part. And what
the rotating handle shows is not switching-off. If applied to the
switch with switching-off padlock, the padlock fails to work.
Therefore, an operator can easily find the melted welding condition
and then further carry out the safety operation. The potential safety
hazards are reduced.

invention or the existing technical proposal, a brief introduction
of drawings demanded by the examples or the existing technical
proposal will be made as follows. Obviously, the drawings in the

[0017] To clearly specify the purpose, the technical proposal and
the advantages of the present invention, the present invention shall
be further particularly described as follows.
[0018] What needs illustration is that all the description involving
"first" and "second" aims at distinguish the two different entities
by the same name or two different parameters by the same name. Such
description is only for convenience and it should not be deemed as
the limitation to the invention examples.No further explanation shall
be made hereafter.
[0019] All terms used for describing the direction or the position
herein, such as "up", "down", "front", "back", "left", "right",
"internal", "external", "top", "bottom" and "side", etc., are used
comparatively to the direction or position of the figure. Therefore,
these terms are only used for illustration and comprehension of the
present invention and shall not be deemed as the limitation on the
scope of protection thereto.
[0020] As shown in Figure 1 to Figure 3, the operating mechanism for
rotary switch comprises a mounting base 1; an operating rod assembly
used for manual rotation 2 and a turntable assembly 3 are arranged
in the claimedmountingbase 1; an energy storage element 4 is arranged
between the claimed operating rod assembly 2 and turntable assembly
3. The turntable assembly 3 realizes switching-on or switching-off
of the switch through forward rotation or reverse rotation. The
operating rod assembly 2 rotates to enable the energy storage element
4 to drive the turntable assembly 3 to rotate. A stop block 5 is hinged
into the mounting base 1 and comprises a promotion part 501 and a
blocking part 502. The turntable assembly 3 and the promotion part
501 work together so that the stop block 5 can rotate to the first
position and the second position relative to the mounting base 1:
when the turntable assembly 3 is located at the switching-on position,
the turntable assembly 3 reaches the promotion part 501 so that the
stop block 5 is at the first position and thereby the blocking part
502 is located on the rotating path of the operating rod assembly
2 or the energy storage element 4 to block and limit the rotation
of the operating rod assembly 2. When the turntable assembly 3 is
located at the switching-off position, the turntable assembly 3 is
separated from the promotion part 501, the stop block 5 is located
at the second position, the blocking and limiting effect on the
rotation of the operating rod assembly 2 from the blocking part 502
is removed. Under normal circumstance, the operating rod assembly
links to the handle and the switching-on or switching-off can be
realized through the rotation of the turntable assembly driven by
the energy storage element after rotating the hand shank. Under the
condition that a contact is melted and welded, the turntable assembly
is kept at the switching-on position and cannot rotate. The turntable
assembly abuts against the promotion part. The operating rod assembly
is prevented from rotating to the switching-off position through the
blockingpart.Andwhat the rotatinghandle shows is not switching-off.
Ifapplied to the switchwith switching-offpadlock, the padlock fails
to work. Therefore, an operator can easily find the melted and welded
condition and then further carry out the safety operation. The
potential safety hazards are reduced.
[0021] The first reset elastic piece 503 is arranged on the claimed
stop block 5 to make the stop block 5 locate at the second position.
[0022] The first limit post 504 is affixed on the promotion part 501
of the claimed stop block 5. The claimed first reset elastic piece
503 is a pressure spring held by the first limit post 504. The claimed
mounting base 1 is equipped with a spring limit slot 101. Driving
to reset can be realized by arranging a torsional spring around the
hinging post.
[0023] The first smooth surface 501 is designed at the side wall of
the claimed promotion part 501 matching the turntable assembly 3.
[0024] In Figure 2, the turntable assembly 3 and the operating rod
assembly 2 are both in switching-on position and stop block 5 locates
at the first position. As shown in Figure 2, when the turntable
assembly 3 anticlockwise rotates, the stop block 5 will anticlockwise
rotates around the hinging post pushed by the first reset elastic
piece 503. When the stop block 5 rotates to the second position, the
blocking and limitation on the rotation of the operating rod assembly
2 by the claimedblockingpart 502 shallbe removed.When the turntable
assembly 3 rotates clockwise to original position, the promotion part
501 is driven by the turntable assembly 3 to make the stop block 5
clockwise rotate around the hinging post and thereby the stop block
gets back to the first position. The blocking part 502 locates on
the rotating path of the energy storage element 4 and its function
is to prevent the continuing rotation of the energy storage element
4 and the operating rod assembly 2. The first smooth surface 505
reduces the friction and contributes to pushing. The energy storage
element 4 has two flexible manipulators 401. When the stop block 5
locates at the first position, the blocking part 502 locates at the
rotating path of the flexible manipulator 401 in the right side as
shown in Figure 4. A limiting bump may be arranged on the operating
rod assembly 2 to match the stop block 5.
[0025] As shown in Figure 4, the claimed operating rod assembly 2
comprises an operating rod 201 and a cam 202 arranged around the
operating rod 201 and in the circumferential direction linked with
the claimed operating rod 201; the claimed turntable assembly 3
comprises a turntable 301 and a sliding block 302 set on the turntable
301 and slides radially relative to the claimed turntable 301; on the claimed mounting base 1 two sliding block slots 102 are arranged corresponding to the switching-on and switching-off positions of the turntable assembly 3; the second reset elastic piece 303 which can make the sliding block 302 insert into the sliding block slot 102 is arranged between the claimed turntable 301 and the sliding block
302; when the claimed sliding block 301 inserts into the slot 102,
the claimed turntable assembly 3 is not rotatable and when the claimed
sliding block 302 leaves the slot 102, the claimed turntable assembly
3 is rotatable; the claimed sliding block 302 is arranged under the
cam 202 and there is an push plate 3011 arranged for the claimed cam
202. The claimed cam202 turns the pushplate 3011to remove the sliding
block from the sliding block slot 102. The arrangement of the cam
and the sliding block help to limitation of the position of the
turntable assembly 3 when rotating to switching-on or switching-off
status and to keep such status.
[0026] The claimed turntable 301 has raised by the side plate 304,
and the side plate 304 has the second spring limit post 305, the push
plate 3011 is disposed by the first through hole 306 through which
the second springlimitpost 305 passes andmatches. The claimedsecond
reset elastic piece 303 is a pressure spring and is sleeved on the
second spring limit post 305. The two ends of the second reset elastic
piece 303 respectively abut against the side plate 304 and the push
plate 3011.
[0027] The claimed mounting base 1 is equipped with a first limit
baffle 103 and a second limit baffle 104 matching the claimed side
plate 304, the claimed side plate 304 rotates between the first limit
baffle 103 and the second limit baffle 104.
[0028] The claimed energy storage element 4 is a disk torsional spring with two flexible manipulators 401, the claimed cam 202 raising up with the first spring roof 203, the claimed sliding block 302 raising up with the second spring roof 307, the first spring roof 203 and the second spring roof 307 are of the same width, the two flexible manipulators 401 rely on the first spring roof 203 and the second spring roof 307 on their two sides respectively.
[0029] The Figure shows a switching-on status. When needs to switch
on, the operating rod 201 and the cam 202 anticlockwise rotates. The
cam 202 pushes the flexible manipulator 401 at the right side shown
in Figure 4 to the switching-on position. The projecting part of the
cam 202 promotes the push plate 3011 and the sliding block 302 leaves
the sliding block slot 102. At this moment, the turntable assembly
3 is rotatable in the mounting base 1. The flexible manipulator 401
at the left side rotates with the turntable assembly 3 to the
switching-on position. When needs to switch off, the cam 202 pushes
the flexible manipulator 401 at the left side as shown in Figure 4
to the switching-off position. At the same time, the push plate 3011
is driven and the sliding block 302 leaves the other sliding block
slot 102. The flexible manipulator 401 at the right side rotates with
the turntable assembly 3 to the switching-off position.
[0030] When the contact is melted and welded, the turntable assembly
3 is not rotatable. When needs to switch off, the operating rod
assembly 2 can only rotate to the position of the blocking part 502
and no more rotation can be made. At this time, loose the operating
handle, the energy storage element 4 will rotate back to the original
position together with the operating rod assembly 2.
[0031] The claimed turntable 301 is provided with a square bump 308,
and the claimed sliding block 302 is provided with a square sliding groove 309 matching with the sliding of the square bump 308.
[0032] The claimed the square bump 308 is disposed by a circular
through hole 3010, and the operating rod 201 inserts into the circular
through hole 3010 from the bottom end so that the operating rod 201
can be fixed.
[0033] As illustrated by Figure 6(b), when the sliding block leaves
the groove, it meets the external circle of the turntable to compose
a cylinder. Side plate 304 arranged on the turntable has a fan-shaped
hump. The fan-shaped hump, together with the first limit baffle 103
and the second limit baffle 104, set a limitation on the rotation
angle. At the same time, the fan-shaped hump matches the promotion
part 501.
[0034] All the disclosures above are some better examples of the
present invention, by which the scope of claims of the present
invention shall not be limited. Thus, some equivalent change made
according to the claims of the present invention shall belong to the
scope of the present invention.
