Abstract
The utility model relates to a switch cabinet accessory, in particular to a locking device for a switch cabinet. The mid-door locking device for the movable switch cabinet comprises a locking bolt, a connection rod, a sliding block, a spring, a check block and a supporting plate. The middle part of the locking bolt is articulated on the supporting plate, and one end of the locking bolt is articulated with the connection rod. The connection rod passes through and is fixedly connected with the sliding block which slides along the supporting plate. The block is fixedly connected to the supporting plate, and the spring is fixedly connected to the check block and can be compressed by the sliding of the sliding block. By adopting the mechanism, when a circuit breaker moves to the work position, the locking device acts quickly to lock the cabinet door firmly, thus avoiding the operators from opening the door by mistake and the faulty operation modes of pulling and inserting the secondary plug and pushing and pulling the trolley by operators. The locking device can effectively increase the safety measures of using the cabinet door, has simple structure, convenient installation and safe and reliable action process.
Description
Technical field
The utility model relates to a kind of switch cubicle annex, relates in particular to a kind of locking device of switch cubicle.
Background technology
On the market, 10kV Medium voltage switch or circuit breaker field in the electric power system popular several cabinet types five done aspect anti-comparative maturity, we can say that general cabinet type satisfies five anti-requirements fully, but aspect protection, still exist some problems to need to solve.Warp discovers that to existing withdraw-type switch cabinet when circuit breaker was in the service position, the cabinet door still can be opened, and will cause great harm to operating personnel's personal safety if break down in the cabinet.Consider that the present stage mechanical latching is the most reliable embodiment, the locking that how to design a mechanism just becomes the key point that addresses this problem.
The utility model content
Technique effect of the present utility model can overcome above-mentioned defective, and door latch apparatus in a kind of withdraw-type switch cabinet is provided, and it can effectively guarantee operating personnel's personal safety.
For achieving the above object, the utility model adopts following technical scheme: it comprises dead bolt, connecting rod, slide block, spring, block, supporting bracket, and the middle part of dead bolt is hinged on the supporting bracket, and an end and the connecting rod of dead bolt are hinged; Connecting rod runs through slide block and affixed with slide block, and slide block slides along supporting bracket; Block is fixed on the supporting bracket, affixed spring on the block, slide block slip compressible spring.
The utility model designs a kind of interlocking device, when circuit breaker arrives the service position, touches this interlocking device, and the interlock action is dead with cabinet door lock, causes the cabinet door to open, thereby has guaranteed operating personnel's personal safety.
Locking device also comprises locating piece, and locating piece is provided with groove, and connecting rod passes locating piece along groove, and connecting rod can slide along groove.Adopt between connecting rod and the slide block and be threaded.
The utility model is on the basis of LISA cabinet shutter mechanism, pushes down the mode of sliding door hinge by stretching out duck hair style dead bolt, and the cabinet door is firmly locked.
By the use of this mechanism, when circuit breaker arrived the service position, locking device moved rapidly, and the cabinet door is locked firmly, avoids personnel's the door operation that opens by mistake, in the misoperation mode of carrying out plug secondary plug and push-and-pull dolly.Blocking mechanism of the present utility model can effectively improve the measure safe in utilization of cabinet door, and is simple in structure, and it is convenient to install, and course of action is safe and reliable.

Fig. 2 is a normal condition schematic diagram of the present utility model;
Fig. 3 is a working state schematic representation of the present utility model.
Embodiment
This device comprises dead bolt 1, connecting rod 2, slide block 5, spring 6, block 7, supporting bracket 3, and dead bolt 1 is arranged to duck ligulate shape, and the middle part of dead bolt 1 is hinged on the supporting bracket 3, and an end and the connecting rod 2 of dead bolt 1 are hinged; Connecting rod 2 runs through slide block 5 and affixed with slide block, and slide block 5 slides along supporting bracket; Block 7 is fixed on the supporting bracket 3, affixed spring 6 on the block 7, and normal condition lower spring 6 just contacts with slide block 5 at the state of elongation naturally.
Locking device also comprises locating piece 4, and locating piece 4 is provided with groove, and connecting rod 2 passes locating piece along groove, and connecting rod 2 can slide along groove.Adopt between connecting rod 2 and the slide block 5 and be threaded.
When circuit breaker is shaken into operating state, circuit breaker can clash into slide block 5, because slide block 5 and connecting rod 2 are affixed, so in the process of moving behind slide block 5, connecting rod 2 moves after also carrying out synchronously, duck tongue shaped dead bolt 1 is under the pulling of connecting rod 2, and end stretches out forward along framework, directly over the arrival hinge, dead bolt 1 compresses slide plate 8, can't mention slide plate 8 this moment under the effect of dead bolt 1, also just can't open the cabinet door.And under this state, slide block 5 is with spring 6 compressions.
When circuit breaker was shaken out cabinet, slide block 5 resetted under the effect of the elastic force of spring 6, connecting rod 2 reaches, and dead bolt 1 is got back to initial position under the drive of connecting rod, and dead bolt 1 separates with slide plate 8, and can mention slide plate 8 this moment, thereby open the cabinet door.
Claims (3)
