Fig. 2 is the installation front view of the misoperation-proof mechanism of low pressure fixed switching cabinet of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to specification text
Word can be implemented according to this.
A kind of way of realization for showing the present invention can be understood by Fig. 1 and Fig. 2, including：
Lock 7：It is provided with through hole, and is fixed on the inner side of door board of switch cabinet 9, for entangling dead bolt 1 to realize lock
The door-plate 9 of switch for locking cabinet.Also, lock 7 can be fixed lock 7 with door board of switch cabinet 9 by screw, can make cap nut
The outside of door board of switch cabinet 9 is stayed in, in the case of facilitating misoperation-proof mechanism failure, lock 7 can be pulled down and open cabinet doors
Carry out maintenance process；
Lock bolt sleeve 6：It is provided with through hole, and it is fixed on the lower section of lock 7, the through hole of the lock bolt sleeve 6 and leading to for lock 7
Hole can be conducive to dead bolt 1 to be moved up and down in the through hole of lock bolt sleeve 6 and lock 7 on the same line, so, and keep hanging down
Straight moves up and down, and realizes that dead bolt 1 can only successfully be moved up and down and can be smoothly embedded in the through hole orientation that lock bolt sleeve 6 is fixed
With the through hole for smoothly departing from lock 7 in the through hole of lock 7, the smooth closing of cabinet door is contributed to lock and opening.Also, lock
Tongue set 6 can be fixed on the mounting rail 8 of disconnecting switch rotating mechanism by welding or screw rod, screw；
Dead bolt 1：In the through hole of its top insertion lock bolt sleeve 6, under disconnecting switch "on" position, the top of dead bolt 1 is also same
When insertion lock 7 through hole in, the entire widths of lock 7 and lock bolt sleeve 6 are more than the width on the top of dead bolt 1, and the top of dead bolt 1 is used
It is used for the door-plate 9 of locking switch cabinet in the through hole of embedded lock 7；
Cam 2：Under disconnecting switch "on" position, its underpart is circle, and top is ellipse, and oval outward flange is set
Guide rail 11 is equipped with, its underpart is fixedly connected with disconnecting switch rotating shaft 10, by the guide rail 11 by under the top of cam 2 and dead bolt 1
Portion's pin connection, and the dead bolt bottom pin 4 of connection is parallel with the disconnecting switch rotating shaft 10.The top elliptical of cam 2
Outward flange is provided with guide rail 11 so that after the bottom of dead bolt 1 is connected by the pin of guide rail 11, realize pendulum of the dead bolt 1 according to cam 2
Dynamic and can move up and down, the bottom of cam 2 is circular can be connected by screw 3 or be welded and fixed with disconnecting switch rotating shaft 10,
Under disconnecting switch "on" position, the oval major axis in the top of cam 2 is in plumbness, and dead bolt 1 also rises to along guide rail 11
Extreme higher position, and it is kept vertical by the through hole of lock 7 and lock bolt sleeve 6, then led by the top of cam 2 ellipse is outer peripheral
Rail 11 tethers to fetch with the lower pin of dead bolt 1 supports dead bolt 1 not fall down, so as to realize that cabinet door is locked, does not allow to open.
Under disconnecting switch gate-dividing state, dead bolt 1 also drops to extreme lower position along the oval outward flange guide rail 11 of cam 2, and passes through
The oval outer peripheral guide rail 11 of through hole and cam 2 of lock bolt sleeve 6 tethers the position for fetching support dead bolt 1 with the lower pin of dead bolt 1, and
Keep dead bolt 1 not fall down, so as to realize that the lock 7 of door board of switch cabinet 9 and dead bolt 1 are separated, just allow to open switch cubicle
Door, is opened, it is ensured that the personal safety of operating personnel so as to ideally prevent cabinet door maloperation.
Particularly, guide rail 11 is annular groove, and the annular groove bottom opening so not only facilitates cam 2 to connect with dead bolt 1
Connect, be easy to cam 2 to drive dead bolt 1 to move up and down again.Particularly, the bottom of dead bolt 1 is inverted U opening, annular groove insertion institute of institute
In the recess for stating inverted U opening, the pin 4 of the bottom of dead bolt 1 is by the opening of the annular groove bottom, by the dead bolt 1
Bottom be connected with cam 2, and the annular groove bottom A/F be more than the bottom pin 4 of dead bolt 1 diameter.Wherein can be with
Pin 4 is fixed from locking pin 5, so that cam 2 drives dead bolt 1 more to stablize when moving.Particularly, the upper end of cam 2
Magnetic material is set, the first proximity Hall switch sensor is provided with the recess of the inverted U opening, in disconnecting switch
Rotating shaft get to separating brake in place state when, be provided with the second proximity Hall switch on the major semiaxis extended line of the ellipse of the cam 2
Sensor, and the first proximity Hall switch sensor, with showing that the signaling module closed a floodgate is electrically connected, second Hall connects
Nearly switch sensor is with showing that the signaling module of separating brake is electrically connected.Under disconnecting switch "on" position, the oval length in the top of cam 2
Axle is in plumbness, and dead bolt 1 also rises to extreme higher position along guide rail 11, and makes it by the through hole of lock 7 and lock bolt sleeve 6
Keep vertical, the first proximity Hall switch sensor sensing on the recess of inverted U opening has magnetic to the upper end of cam 2
Property material, as in-place closing signal, and be transferred to display close a floodgate signaling module, can show on cabinet door plate 9 combined floodgate
Information, may further determine that the position of disconnecting switch.Under disconnecting switch gate-dividing state, dead bolt 1 is outer along the ellipse of cam 2
Edge guide 11 drops to extreme lower position, at this moment magnetic of the second proximity Hall switch sensor sensing to the upper end of cam 2
Property material, as separating brake signal in place, and be transferred to the signaling module of display separating brake, the letter of separating brake can be shown on cabinet door plate
Breath, so as to further determine that the position of disconnecting switch, both safely, simply, conveniently, and hommization.
In another embodiment, the through hole length of lock bolt sleeve 6 can elect 10-35mm as, and the through hole of lock bolt sleeve 6 is wide
Degree can select the big 2-10mm of width than the top of dead bolt 1.It can so make dead bolt 1 more successfully in the through hole of lock bolt sleeve 6
Move up and down, and be easy to keep dead bolt 1 to be in plumbness.
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed
With it can be applied to various suitable the field of the invention completely, can be easily for those skilled in the art
Other modification is realized, therefore under the universal limited without departing substantially from claim and equivalency range, the present invention is not limited
In specific details and shown here as the legend with description.
