Abstract
An explosion-proof button comprises a button substrate. A bidirectional button, an elastic rubber sheet, a left conductive elastic sheet, a right conductive elastic sheet and a reset spring are arranged inside the button substrate; the bidirectional button is provided with a convex head; a lower end of the convex head contacts with an upper surface of the elastic rubber sheet; a lower surface of the elastic rubber sheet contacts with the right conductive elastic sheet; the left conductive elastic sheet and the reset spring are respectively arranged below the right conductive elastic sheet; the reset spring is connected with the right conductive elastic sheet; and the left conductive elastic sheet and the right conductive elastic sheet are respectively provided with an externally-wiring wire. The explosion-proof button of the utility model has the advantages of structural simplicity, low manufacturing cost, great convenience in replacement, favorable sealing performance, reliable operation and small dimension, and can be applicable to many occasions.
Description
Technical field
The utility model relates to a kind of button, especially relates to a kind of explosion-proof button.
Background technology
At present, in inflammable and explosive industrial production environment, all require to use explosion-proof electric apparatus, such as explosion-proof electrical distribution box, explosion-proof control box and explosion-proof button etc.With regard to explosion-proof button, existing explosion-proof button adopts the composite type button or adopts the control of electromagnetism light current, and it has the following disadvantages: the internal structure relative complex is difficult to guarantee reliability under rugged environment.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in structure, good seal performance, the more reliable explosion-proof button of working.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of explosion-proof button, comprise the button matrix, be provided with two-way button in the described button matrix, the India rubber sheet, left electroconductive elastic sheet, right electroconductive elastic sheet and back-moving spring, described two-way button is provided with plush copper, the lower end of described plush copper contacts with the upper surface of India rubber sheet, the lower surface of described India rubber sheet contacts with right electroconductive elastic sheet, described left electroconductive elastic sheet and back-moving spring lay respectively at the below of right electroconductive elastic sheet, described back-moving spring links to each other with right electroconductive elastic sheet, on the described left electroconductive elastic sheet the first external connection is housed, on the described right electroconductive elastic sheet the second external connection is housed.
The course of work: promote two-way button to the right, boss on the two-way button makes the India rubber sheet produce downward deformation, the India rubber sheet moves down the left end of right electroconductive elastic sheet, back-moving spring is in compressive state, when the boss on the two-way button moves to the centre position of button matrix, right electroconductive elastic sheet contacts turning circuit with left electroconductive elastic sheet; Otherwise under the effect of back-moving spring, right electroconductive elastic sheet and left electroconductive elastic sheet are from, open circuit.
The utility model utilizes India rubber sheet and button matrix that left electroconductive elastic sheet, right electroconductive elastic sheet and back-moving spring are hedged off from the outer world, thereby carries out explosion-proof.
Compared with prior art, the utility model is simple in structure, and low cost of manufacture is changed very easy; Sealing property is better, works more reliable; Volume is little, and applicable situation is many.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to accompanying drawing, the present embodiment comprises button matrix 1, be provided with two-way button 2 in the described button matrix 1, India rubber sheet 4, left electroconductive elastic sheet 5, right electroconductive elastic sheet 6 and back-moving spring 7, described two-way button 2 is provided with plush copper 3, the lower end of described plush copper 3 contacts with the upper surface of India rubber sheet 4, the lower surface of described India rubber sheet 4 contacts with right electroconductive elastic sheet 6, described left electroconductive elastic sheet 5 and back-moving spring 7 lay respectively at the below of right electroconductive elastic sheet 6, described back-moving spring 7 links to each other with right electroconductive elastic sheet 6, on described left electroconductive elastic sheet 5 and the right electroconductive elastic sheet 6 external connection is housed respectively.
The course of work: promote two-way button 2 to the right, boss 3 on the two-way button 2 makes India rubber sheet 4 produce downward deformation, India rubber sheet 4 moves down the left end of right electroconductive elastic sheet 6, back-moving spring 7 is in compressive state, when the boss 3 on the two-way button 2 moves to the centre position of button matrix 1, right electroconductive elastic sheet 6 contacts turning circuit with left electroconductive elastic sheet 5; Otherwise under the effect of back-moving spring 7, right electroconductive elastic sheet 6 and left electroconductive elastic sheet 5 are from, open circuit.
