Problems solved by technology

[0004] In this structure, the sealing ring is in contact with the body (or cover) and the movable shaft by its own tension and the elastic force of the spring, so as to play a protective role. When the button head is operated, the gap between the moving part and the fixed part of the button head Cannot effectively prevent water ingress

Abstract

The invention relates to a structure of an operating part of an explosion prevention button head, which comprises: a cover (10) and a body (20) connected with the cover (10); a cavity formed by the cover (10) and the body (20) and comprising an operating part (30) on the upper part and a baffle plate (91) on the lower part; a first spring (40), a clamp ring (60), a telescopic sealing ring (50), a sliding shaft (70) and a second spring (80) which are arranged below the operating part (30) in turn; and a fixing mechanism (90) which is arranged below the sliding shaft (70). Through the connection and the transition of the telescopic sealing ring (50), the body (20) and the cover (10) as well as the clamp ring (60) and the sliding shaft (70) are connected into a whole body, and gaps between the four components are shielded effectively to achieve good protecting performance.

Description

Technical field [0001] The invention relates to an explosion-proof button head, in particular to the operation part structure of the explosion-proof button head. Background technique [0002] The explosion-proof button head is a button structure used in explosion-proof electrical products in the explosion-proof industry and assembled on the operation panel or other lamps and lanterns to operate the internal buttons. [0003] by figure 1 , figure 2 It can be seen that the explosion-proof button head is generally composed of a fixed part (cover 1, body 2) and a movable operation part (movable shaft 3, spring 4, sealing ring 5). The fixed part plays the role of button installation and protection, and the operation part is the button activity Operate the role of internal components. [0004] In this structure, the sealing ring is in contact with the body (or cover) and the movable shaft by its own tension and spring force, thereby playing a protective role. The gap between the moving p...
