Background technology
Breaker is divided into high-voltage circuitbreaker and low-voltage circuit breaker by its use scope.Low-voltage circuit breaker is also known as automatic switch,
It is commonly called as " air switch " and also refers to low-voltage circuit breaker, it is a kind of existing manual switch effect, and can carry out decompression automatically, owe
The electric appliance of pressure, overload and short-circuit protection.It can be used to distribute electric energy, infrequently start asynchronous motor, to power circuit and
The implementations such as motor are protected, when serious overload or short circuit and the failures such as under-voltage occurs in they can automatic shutdown circuit,
Function is equivalent to Fuse switch and crosses the combination of underheat relay etc., and need not generally become after disjunction fault current
More parts have had been widely used.
When short circuit or overload occur for circuit, circuit breaker internal mechanism action is threaded off automatically, cuts off circuit, electricity
After the troubleshooting of road, operable breaker closing recloses circuit.Existing common breaker usually rely on handle directly with
Buckle releaser tripping coordinates, but handle by Effect of Materials is made because easily deformed, so as to cause when coordinating with tripping
Angle, force value change, and influence the reliability of product.Another aspect handle is influenced by with cover auxiliary section, shape by
To limitation, causes the shape with tripping hasp face contact position to be restricted, reduce the stability of transmission.
Invention content
The purpose of the present invention directly reduces buckle releaser tripping and resets aiming at above-mentioned circuit breaker handle with buckle releaser cooperation
The technological deficiency of stability provides a kind of transmission mechanism of breaker, and by increasing plate pushing structure, handle passes through push plate and dropout
Device links, and can effectively improve the stability of buckle releaser reset.
Technical solution
In order to achieve the above technical purposes, a kind of transmission mechanism for breaker that the present invention designs, it includes handle, transmission
Mechanism and buckle releaser, it is characterised in that:Rushing board mechanism on the transmission mechanism, the handle by the rushing board mechanism with
The buckle releaser linkage can push the buckle releaser to reset.
Further, the rushing board mechanism includes push plate, and the push plate is on the push plate axis, the both ends of the push plate axis
On the transmission mechanism, torsional spring is located at the inside of the push plate on the push plate axis, and the both ends of the torsional spring resist
The push plate madial wall.
Further, the tail portion of the push plate is U-shaped bending, can be with the push plate outside wall in the handle rotation process
It contacts that the push plate is pushed to rotate, U-shaped bending can be contacted with the buckle releaser in the push plate rotation process realizes institute
Buckle releaser is stated to detain again.
Further, the push plate outside wall can limit the handle equipped with positive stop lug boss and be slided along the push plate outside wall
It is dynamic.
Further, the push plate makes for metal material.
Advantageous effect
A kind of transmission mechanism of breaker provided by the invention, by increasing plate pushing structure, handle passes through push plate and dropout
Device links, and can effectively improve the stability of buckle releaser reset.

Specific implementation mode
With reference to the accompanying drawings and examples, the present invention will be further described.
Embodiment
As shown in figure 1 and 2, a kind of transmission mechanism of breaker, it includes handle 1, transmission mechanism 2 and buckle releaser 3,
In, rushing board mechanism 4 is on the transmission mechanism 2, as shown in Fig. 5, the handle 1 by the rushing board mechanism 4 with it is described
The linkage of buckle releaser 3 can push the buckle releaser 3 to reset.
As shown in attached drawing 1,3,4 and 10, the rushing board mechanism 4 includes metal push plate 401, and the push plate 401 is mounted in described
On push plate axis 402, the both ends of the push plate axis 402 are on the transmission mechanism 2, and torsional spring 403 is on the push plate axis 402
Positioned at the inside of the push plate 401, the both ends of the torsional spring 403 resist 401 madial wall of the push plate.
As shown in attached drawing 6,7,8 and 9, the tail portion of the push plate 401 is U-shaped bending, energy in 1 rotation process of the handle
It is enough to contact that the push plate 401 is pushed to rotate with 401 lateral wall of the push plate, U-shaped bending in 401 rotation process of the push plate
It can be contacted with the buckle releaser 3 and realize that the buckle releaser 3 is detained again.
401 lateral wall of the push plate, which is equipped with positive stop lug boss 401a, can limit the handle 1 along 401 outside of the push plate
Wall slides.
As shown in Fig. 1, when mechanism is not detained again, handle 1 is not in contact with push plate 401, and push plate 401 is in torsional spring 403
Initial position can be maintained under twisting force.When transmission mechanism 2 is detained again, handle 1 pushes push plate 401 to be transported to buckle releaser 3
Dynamic, when moving to certain stroke, the U-shaped bending contact trip device tripping 5 and 6 in push plate 401 makes the realization of buckle releaser 3 detain again, and
When handle 1, which continues to press on push plate 401, to be moved, at a time, one end that handle 1 is contacted with push plate 401 can touch push plate
Positive stop lug boss 401a on 401, at this time handle 1 be such as rotated further, by push push plate 401 continue to move, it is U-shaped in push plate 401
Bending continues contact trip device tripping 5 and 6, but does not influence the realization of buckle releaser 3 and detain again.One end that handle 1 is contacted with push plate 401 after
Reforwarding is against when dynamic on the positive stop lug boss 401a in push plate 401, avoids the deformation of one end that handle 1 is contacted with push plate 401.When
When not having positive stop lug boss 401a in push plate 401, one end that handle 1 is contacted with push plate 401 will continue to slide along 401 lateral wall of push plate
Dynamic, one end that handle 1 contact with push plate 401 can be bent downwardly, and one end that handle 1 is contacted with push plate 401 is caused to deform, influence with
Afterwards with the cooperation of push plate 401, harmful effect is caused to detaining again.
The present embodiment is effectively prevented in original machine structure, handle 1 and 3 tripping of buckle releaser are direct by increasing rushing board mechanism 1
Contact complete mode that buckle releaser 3 is detained again because handle 1 because the problems such as material is easily deformed cause mechanism to buckle again when, buckle releaser
The phenomenon that state labile is detained in tripping appearance again.The stability when work of switching device transmission mechanism is effectively improved, by machine
When structure is detained again, the probability that 3 tripping of buckle releaser occurs detaining failure again reduces 30%~50%.
Structure, ratio, size, quantity etc. depicted in institute of embodiment of the present invention accompanying drawings, only coordinating specification
Revealed content is not limited to the enforceable restriction item of the present invention so that those skilled in the art understands and reads
Part, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influencing
Under the effect of present invention can be generated and the purpose that can reach, it should all still fall and obtain and can contain in disclosed technology contents
In the range of lid.Meanwhile it is cited such as "upper", "lower", "left", "right", " centre ", " clockwise ", " inverse time in this specification
The term of needle " etc. is merely convenient to being illustrated for narration, rather than to limit the scope of the invention, relativeness
It is altered or modified, in the case where changing technology contents without essence, when being also considered as the enforceable scope of the present invention.
