Embodiment Construction

[0026] Specific embodiments of the present invention such as Figure 1-5 As shown, an anti-shock device for a travel switch includes a push rod 11, a push rod 12 and a buffer spring 13. The push rod 12 is provided with a hollow cavity 121 with an opening 1211 at one end, and the buffer spring 13 is located in the hollow cavity 121, one end of the push rod 11 extends into the hollow cavity 121 through the opening 1211 and abuts on the buffer spring 13, and the other end of the buffer spring 13 abuts on the spring seat 1212 arranged in the hollow cavity 121, so An outwardly extending top 14 is provided on the end of the push rod 12 away from the push rod 11 , and a limiting shoulder 123 is formed at the connection between the top 14 and the push rod 12 . The push rod 11 can be pressed along the axial direction of the push rod 12. The buffer spring 13 has both buffering and reset functions. The top 14 is used to support and contact the contacts of the contact assembly. The settin...

Abstract

The invention relates to the technical field of travel switches and particularly discloses an anti-impact device of a travel switch and the travel switch. The anti-impact device comprises a push rod, an ejector rod and a buffer spring, wherein the ejector rod is provided with a hollow cavity with an opening at one end, and the buffer spring is located in the hollow cavity; one end of the push rod extends into the hollow cavity through the opening and abuts against the buffer spring, the other end of the buffer spring abuts against a spring seat arranged in the hollow cavity, the end, away from the push rod, of the ejector rod is provided with a top extending outwards, and a limiting shoulder step is formed in the connecting position of the top and the ejector rod. By adopting the structure, the anti-impact device of the travel switch and the travel switch which are simple to assemble, high in production efficiency and capable of solving a problem that a product fails due to collision and the like are provided.

Description

technical field [0001] The invention relates to the technical field of travel switches, in particular to an anti-shock device for a travel switch and a travel switch. Background technique [0002] At present, the existing anti-shock devices have complex structures, many parts, cumbersome assembly, and low production efficiency; , can not be stopped in time, it will damage the structure of the contact module, resulting in product failure. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an anti-shock device and a travel switch for a travel switch that are simple to assemble, have high production efficiency, and can solve problems such as product crash failure. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: an anti-shock device for a travel switch, including a push rod, a push rod and a buffer spring, the push rod is provided with a hollow cav...
