Description
Technical field
It the utility model is related to switch cubicle technical field, and in particular to a kind of door of switch cabinet and the chain dress of breaker
Put.
Background technology
According to being actually needed for switch cubicle product, can be in the purpose of cabinet installation locking door device, locking door device
Special messenger is needed to go to unlock in right times, panel could be opened.
Door lock assembly of the prior art is typically only capable to control the unlatching of door-plate, does not accomplish chain with circuit breaker position.By
Door-plate is opened and easily causes accident when breaker is in operating position, is unfavorable for the personal safety of staff, so prior art
Door lock assembly can not realize that breaker can not be opened in operating position door-plate, for breaker in testing position, door-plate just can be with
Open, can thus produce potential safety hazard, be unfavorable for the personal safety of staff.
Utility model content
The utility model is in view of the shortcomings of the prior art, there is provided a kind of door of switch cabinet and breaker interlock, tool
Have it is simple in construction, it is safe and reliable, linksystem is strong and the advantages of being easily installed.
The utility model is achieved by the following technical solution：
A kind of door of switch cabinet and breaker interlock, including cabinet door and the breaker in cabinet, institute are provided
The breaker stated is fixed in cabinet by chassis frame, is fixed with installing plate on the inside of described cabinet door, on described installing plate
The flap that can be rotated between circuit breaker panel and chassis frame is rotatably connected to, described flap turns close to one end of breaker
It is dynamic to be connected with the roller that rolled on circuit breaker panel, described flap in rotation process its close to one end of breaker
Vertical height is fixed with downward projection higher than it on one end of cabinet door, described flap, described chassis frame by
Nearly cabinet door side is fixed with the block that coordinates and can limit flap rotation with projection.
One end of flap is be hinged on a mounting board, and the other end of flap is hinged roller, and when cabinet door is closed, breaker is by testing
Position is shaken when entering operating position, and flap falls, and the projection on flap can prop up the block on the chassis frame of breaker, cabinet door
It can not open；It can be withstood when breaker is shaken out to testing position by operating position, during circuit breaker panel moving process on flap
Roller, roller rotate along circuit breaker panel, drive the projection on flap to lift, cabinet door can be opened normally.
Preferably, described projection is the hook-type projection towards block bending.
Hook-type projection can well with chassis frame front end baffle fit, catch on block, breaker and door-plate can be achieved
It is chain.
Further, the both ends of described flap are hinged with installing plate and roller respectively by bearing pin.
Further, it is arranged with back-up ring on the shaft end of described bearing pin.
Back-up ring is arranged in the shaft end of bearing pin, prevents bearing pin from being slided in for a long time with flap rotation process, causes bearing pin
Slide so that bearing pin separates with flap, can not realize chain function.
The beneficial effects of the utility model：By setting the block on the chassis frame of projection and breaker to match somebody with somebody on flap
Close, realize that cabinet door is chain with breaker, the utility model is simple in construction, and securely and reliably, linksystem is strong and is easily installed.

Embodiment
For the technical characterstic for illustrating this programme can be understood, below by embodiment, this programme is illustrated.
A kind of door of switch cabinet and breaker interlock, including cabinet door 1 and the breaker in cabinet, it is described
Breaker is fixed in cabinet by chassis frame 9, and the described inner side of cabinet door 1 is fixed with installing plate 2, installing plate 2 and cabinet door 1
Mounting means can be the mode such as bolt connection, riveting, gluing.
It is rotatably connected to and can be rotated between circuit breaker panel 10 and chassis frame 9 by bearing pin 4 on described installing plate 2
Flap 6, described flap 6 is rotatably connected to and can be rolled on circuit breaker panel 10 by bearing pin 4 close to one end of breaker
Roller 8, be arranged with back-up ring 3 on the shaft end of described bearing pin 4, prevent bearing pin 4 from being slided in for a long time with the rotation process of flap 6
It is dynamic, cause bearing pin 4 to slide so that bearing pin 4 separates with flap 6, can not realize chain function.
Described flap 6 its vertical height close to one end of breaker in rotation process is higher than it close to cabinet door 1
One end, this ensure that after cabinet door 1 and breaker are chain, when reopening cabinet door 1, when promoting breaker to testing position, turn
Roller 8 on plate 6 can roll along circuit breaker panel 10, realize unblock.Under normal circumstances, flap 6 is that the center of circle can be with bearing pin 4
Into 80 ° of rotations.
Downward projection 7 is fixed with described flap 6, described projection 7 is the hook-type projection 7 towards block bending.
Described chassis frame 9 coordinates and can limited the block 5 of the rotation of flap 6 being fixed with close to the side of cabinet door 1 with projection 7.
When needing to lock cabinet door 1, cabinet door 1 is closed, breaker is shaken by testing position enters operating position, on flap 6
Hook-type projection 7 falls, and hooks the block 5 on chassis of circuit breaker vehicle frame 9, and now cabinet door 1 locks with breaker；When needing to open
During cabinet door 1, breaker can be shaken with rocking handle, breaker is shaken out to testing position, circuit breaker panel 10 by operating position and withstood
Roller 8 lifts flap 6, i.e., hook-type projection 7 lifts on flap 6, is separated with the chassis frame 9 of breaker, while can open
Cabinet door 1.
Certainly, described above is also not limited to the example above, and technical characteristic of the utility model without description can lead to
Cross or realized using prior art, be will not be repeated here；Above example and accompanying drawing are merely to illustrate technology of the present utility model
It is to limitation of the present utility model that scheme, which is not, and the utility model is described in detail with reference to preferred embodiment, this
Field it is to be appreciated by one skilled in the art that those skilled in the art institute in essential scope of the present utility model
For the variations, modifications, additions or substitutions made without departure from objective of the present utility model, should also belong to right of the present utility model will
Seek protection domain.
