Description
Technical Field
The utility model belongs to the technical field of mining flame-proof type device external member, specifically a mining modularization screw fastening formula explosion-proof button external member.
Background
Most of the conventional coal mine explosion-proof equipment is provided with different numbers of explosion-proof buttons for external operation, the processed buttons are welded on an explosion-proof shell in a general welding mode, and for the condition that a plurality of groups of buttons with small gaps cannot be welded, long sleeves with a plurality of buttons connected in parallel are directly processed for being welded with the explosion-proof shell. Due to the processing characteristics of the traditional mode, the problem of hot processing deformation exists in the traditional mode, and the processing size of the welded explosion-proof surface can be ensured only by performing fine trimming at the later stage. The assembly process is complicated and inconvenient to operate. In addition, in the future use, along with the increase of the explosion-proof clearance caused by the abrasion of the copper sleeve, the copper sleeve is in interference fit, the button sleeve is integrally welded, and the button can hardly be maintained and replaced by the mode.
Disclosure of Invention
To the not enough of above-mentioned prior art, the embodiment of the utility model provides a technical problem who solves provides a mining modularization screw fastening formula explosion-proof button external member.
In order to solve the technical problem, the utility model provides a following technical scheme:
a mining modularized screw fastening type explosion-proof button kit comprises a button rod, an elastic piece, a button sleeve, a locking piece and a retainer ring contact,
the button sleeve is arranged in the preformed hole of the explosion-proof shell and is fixedly connected with the explosion-proof shell through the locking piece,
the retaining ring contact is arranged on one side of the locking piece away from the button sleeve,
the button rod penetrates through the retainer ring contact, the locking piece and the button sleeve in sequence,
the sleeve is arranged at the inner side of the button sleeve,
the elastic piece is arranged inside the button sleeve and used for providing resilience force for the button rod.
As a further improvement of the utility model: the sleeve is in interference fit with the button sleeve.
As a further improvement of the utility model: the sleeve is made of brass material.
As a further improvement of the utility model: the button rod is connected with the retainer ring contact through a screw.
As a further improvement of the present invention: the button sleeve, the button rod and the retainer ring contact are made of stainless steel.
As a further improvement of the present invention: the elastic piece is a compression spring.
As the utility model discloses further improvement scheme again: the locking piece is a locking nut.
Compared with the prior art, the beneficial effects of the utility model are that:
the embodiment of the utility model provides a have compact structure, anticorrosive rust-resistant, dismantled and assembled maintenance change's characteristics, can form standard part batch processing for the supporting use on the flame proof shell surface of the various different forms of flame proof shell operating button demand.
