Description

Isolator

Technical field

This utility model relates to a kind of contactor, more specifically, it relates to a kind of isolator.

Background technology

Isolator, namely isolates switch.

At present, the Chinese patent of open (bulletin) number CN104241006A on market discloses a kind of isolation switch, and described break-make indicating mechanism includes indication piece, elastic reset part, and described indication piece is articulated and connected by the first round platform and enclosure interior；Described handle is provided with the pushing part that can promote indication piece；Resetted by elastic reset part when described indication piece is provided with combined floodgate and when showing the primary importance closed a floodgate and separating brake, propped up the second position of display separating brake by the pushing part of handle.

This isolation switch, although only just can be switched state when combined floodgate or separating brake by torsion spring and handle very easily, but cannot lock handle position, handle is unexpected separating brake easily, causes potential safety hazard.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is in that to provide a kind of isolator with lock handle function.

For achieving the above object, this utility model provides following technical scheme: the handle that include housing, is hinged on housing, latch-up structure for lock handle, described latch-up structure includes the locking piece being rotatably connected on housing, described locking piece one end connects the lock dog for limiting handle position, the other end arranges the knob being positioned at outside housing, during separating brake, described lock dog rotate to handle clamping；During combined floodgate, described lock dog rotates to separating with handle.

By rotary knob, lock dog is driven to rotate, thus pinning handle and preventing from rotating when lock dog projection and handle clamping.Only being operated by knob and can be achieved with handle position locking, simple in construction is easy to operate.

Further, described knob is provided with the bar of instruction lock dog position.

Bar can show the state of lock dog, it is simple to operator knows lock dog position, thus indicating the current state of handle.

Further, it is shown that bar is groove.

Utilize groove as bar, it is to avoid bar weares and teares after a long time use, extend its life-span, and processing is simple.

Further, described lock dog is integrated the bar shaped projection being arranged on locking piece, and its one end is used for and handle clamping.

Lock dog is one-body molded, and processing is simple, it is simple to install.And lock block structure is less, if being divided into multiple component, easily lose during mounting or dismounting.Product structure can be simplified after being wholely set, reduce the number of components.

Further, being provided with movable contact spring, static contact and elastic component in housing, described handle is connected with movable contact spring, and when separating brake, described elastic component keeps separating movable contact spring with static contact.

When separating brake, utilize elastic component that movable contact spring is applied the power away from static contact, it is ensured that movable contact spring separates when separating brake in time with static contact, decrease the response time that circuit disconnects, improve its safety.

Further, described elastic component is spring, and described movable contact spring arranges round bump, and described housing arranges the fixing groove of elastic component；Described spring one end and projection clamping, the other end is connected in the fixing groove of elastic component.

Interface arrangment is utilized to fix spring, simple in construction, easy for installation.

Further, described housing being provided with draw-in groove, described lock dog is positioned at draw-in groove.

Draw-in groove can limit the position of lock dog, it is prevented that lock dog position offsets.The clamping position of lock dog and handle can also be limited, it is ensured that snap effect.

Further, described draw-in groove is between movable contact spring and handle.

Described draw-in groove, between movable contact spring and handle, optimizes the interior spatial structure of chopper, improves space availability ratio, it is possible to reduce chopper volume.

By adopting technique scheme, this utility model has the advantage that 1, may indicate that lock dog state.2, locking function need not be realized by other extraneous structures.3, simple in construction, space availability ratio is high, easy to operate.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in further detail.

Embodiment one: a kind of isolator, including the housing 1 that two lobes cover, installs moving contact 22 and static contact 21 in housing 1, hinged handle 2 above housing 1, handle 2 is connected towards the one end in housing 1 with moving contact 22, also has draw-in groove 11, be provided with locking piece 31 in draw-in groove 11 on housing 1.Described locking piece 31 one end is integrally raised with the lock dog 312 for limiting handle 2 position, and the other end arranges the knob 313 being positioned at outside housing 1.2 surpassing the block structure also with projection to the one end in housing 1 at handle, namely lock dog 312 is conflicted and is realized the locking position of handle 2 in this block structure.During separating brake, described lock dog 312 rotate to handle 2 clamping；During combined floodgate, described lock dog 312 rotates to separating with handle 2.Also setting up groove on knob 313, this groove is used for showing lock dog 312 position as bar 311.

Described draw-in groove 11, between movable contact spring 22 and handle 2, optimizes the interior spatial structure of chopper, improves space availability ratio, it is possible to reduce chopper volume.Draw-in groove 11 is provided with and the opening of handle 2 UNICOM, and lock dog 312 can pass through aperture position and handle 2 clamping, it is prevented that other positions of lock dog 312 and handle 2 come in contact and locked handle 2, cause fault.

During use, handle 2 is broken to gate-dividing state, if desired lock handle 2 position, by rotary knob 313, drive lock dog 312 to rotate.Lock dog 312 projection and handle 2 clamping, just can pin handle 2 and prevent from rotating.Handle 2 position when opening a sluice gate can not only be fixed by knob 313, also can fix handle 2 position when closing lock, and simple to operate.Operation process in, it is possible to by observe groove towards, if during groove level, handle 2 is locked；When groove is vertical, for Unlocked state.

Lock dog 312 one end is protruded, and only when handle 2 is blocked in this one end, handle 2 rotation can be restricted, and handle 2 motion is not easily susceptible to other structure influences of lock dog 312.And lock dog 312 not easily affects other structures except handle 22.Long-time use, groove is not easy to fuzzy being beyond recognition as bar 311, and processing technique is simple.

Embodiment two: as shown in Figures 1 to 3, the present embodiment differs only in embodiment one, also includes elastic component 23, and described handle 2 is connected with movable contact spring 22, and when separating brake, described elastic component 23 keeps separating movable contact spring 22 with static contact 21.Described elastic component 23 is spring 231, and described movable contact spring 22 arranges round bump 232, and described housing 1 arranges the fixing groove 233 of elastic component；Described spring 231 one end and projection 232 clamping, the other end is connected in the fixing groove 233 of elastic component.

When handle 2 is in "on" position, spring 231 is compressed, and to the power that movable contact spring 22 is downward, during separating brake, moving contact 22 is applied elastic-restoring force by spring 231 so that separating brake is more laborsaving, simultaneously separating closer to rapidly between moving contact 22 and static contact 21.

This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made the amendment not having creative contribution as required by those skilled in the art after reading this specification, but as long as being affected by the protection of Patent Law in right of the present utility model.
