Description
Technical Field
The utility model relates to a circuit breaker technical field, concretely relates to circuit breaker buckle mechanism.
Background
The circuit breaker is a switching device capable of closing, carrying, and opening a current under a normal circuit condition, and closing, carrying, and opening a current under an abnormal circuit condition (including a short-circuit condition) within a prescribed time. The circuit breaker is equipped with the buckle in its bottom, and current buckle mechanism has following shortcoming: 1, the clamping head is not firmly clamped and is easy to slide; 2, the spring is inconvenient to mount, the tension of some springs is very large, the springs can be pulled only with great effort, and even though the buckle can be pulled by using a tool, the excessive force is easy to damage components and parts; the 3-hook structure is not stable in sliding or is difficult to slide due to the fact that the spring is not fixed firmly in the pulling process.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problem, the to-be-solved technical problem of the utility model is to provide a circuit breaker buckle mechanism that the pulling is steady, easy dismounting, stable in structure.
The utility model discloses technical scheme that circuit breaker buckle mechanism adopted include the dop, with the dop is with wide guide rail frame, establish guide rail frame below and with spacing lug that the dop is connected, with spacing lug is connected and is established buckle elastomer in the guide rail frame, its characterized in that: the clamping head is of a triangular structure, clamping head arc grooves are formed in the clamping head, abdicating notches and abdicating grooves are formed in the front side and the rear side of the guide rail frame, a handle groove is formed in the middle of the right side of the guide rail frame, the buckle elastic body is of a wavy structure, a reinforcing rod is arranged on the buckle elastic body, and a contact convex block is further arranged at the tail of the buckle elastic body.
The chuck circular arc groove quantity is 2 and for interval arrangement.
The tail part of the guide rail frame is provided with a step gap.
The width of the limiting lug is smaller than that of the guide rail frame.
The thickness of the buckle elastomer is a, and the alpha is more than 0.5cm and less than 1.5 cm.
The utility model discloses circuit breaker buckle mechanism's advantage lies in: 1, the elastic structure of the buckle enables the buckle not to be fixed by the tension of a spring, and can also be quickly clamped and released, so that the installation is simpler, and the installation is convenient and quick; 2, due to the structural design of the arc groove of the clamping head, the clamping buckle can be more stable and firm in clamping and is not easy to fall off; 3 the notch of stepping down and the groove design of stepping down can make the buckle back-and-forth movement area of contact little, and it is lighter to slide, is difficult for blocking.

The buckle elastic body 8 is of a wave-shaped structure, the reinforcing rod 13 is arranged on the buckle elastic body, the tail portion of the buckle elastic body is further provided with a contact convex block 14, the structural design of the buckle elastic body enables the buckle not to be additionally fixed by being matched with a spring in a tension mode, the elastic buckle can be in a locking state and a releasing state due to the special elastic deformation structure of the buckle elastic body, the overall structure of the buckle is simpler and is convenient to install, and the buckle elastic structure is more stable and firm in the clamping and releasing process due to the design of the contact convex block.
The tail part of the guide rail frame 6 is provided with a step gap 15.
The width of the limiting lug 7 is smaller than that of the guide rail frame 6.
The thickness of the buckle elastic body 8 is a, alpha is more than 0.5cm and less than 1.5cm, the buckle elastic body in the range not only ensures elasticity, but also prevents the clamping from being too tight, and the buckle elastic body is better mounted and dismounted.
The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the present invention, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention are all included within the protection scope of the present invention.
