Abstract
The utility model discloses a flame-proof switch with the object of providing a flame-proof switch that has a good flame-proof capacity and is convenient to operate. The switch comprises a switch, a switch body, and a switch operating mechanism. All these components are connected in an successive order. The switch body is provided with two holes. Both holes are provided with end parts. The tops of the end parts are provided with bearings. The bearings are sleeved with springs. The springs are arranged at the tops of the end parts. The bearings are provided with screw threads, and the screw threads are connected with screw caps. The switch operating mechanism can be controlled by hand or by a pressing button. The operating mechanism contains two protruding points and the switch itself contains two contacts.
Description
Technical field
The utility model relates to switch, and what be specifically related to is a kind of explosion-proof switch.
Background technology
Switch flame proof effect on flameproof cabinet is in the market bad, and reason is that it is directly to realize by button control, and the direct connecting valve of button, if spark appears in button, will directly cause switch failure.
In addition, the operating mechanism on flameproof cabinet, adopts button form substantially, and switchtype is more single.
The defect existing in flameproof cabinet in view of above-mentioned existence, intercepts spark parts if be provided with in switch, spark cannot be passed in flameproof cabinet and form ignition source, and its security performance just improves, and the practicality of product is stronger.
Utility model content
The purpose of this utility model is in order to provide a kind of flame proof effective, easy to operate explosion-proof switch.
For realizing the purpose of this utility model, the utility model adopts following technical scheme: a kind of explosion-proof switch, comprise the switch 1, switch body 2 and the switch operating mechanism that connect in turn, in wherein said switch body, be provided with two holes, in two holes, be equipped with end, the top of end is provided with axle, on described axle, cover has spring, described spring is positioned at the top of end, and described axle top is provided with screw thread, coupling nut on described screw thread.
As preferably, described switch operating mechanism is handle type or push button.
As preferably, in described switch operating mechanism, be provided with two salient points.
As preferably, in described switch, be provided with two contact points.
The beneficial effects of the utility model: be provided with two holes in switch body, in two holes, be equipped with end, the top of end is provided with axle, on described axle, cover has spring, described spring is positioned at the top of end, strengthens the performance of flame proof, has realized explosion-proof switch safer when in use, adopt handle type or push-button switch operating mechanism, use more convenient.
Brief description of the drawings
Fig. 1 is the structure cutaway view of utility model;
Fig. 2 is the switch body vertical view of utility model;
Fig. 3 is the front section view of the switch body that parts are not installed of utility model.
Hole is 12, and screw thread is 11, and end is 10, and contact point is 9,, salient point is 8, and switch operating mechanism is 7, and shell cover is 6, and spring is 5, and axle is 4, and nut is 3, and switch body is 2, switch is 1.
Embodiment
Further illustrate below in conjunction with accompanying drawing:
As described in Fig. 1-3, the utility model comprises switch body 2, switch 1, switch operating mechanism 7, in described switch body, 2 are provided with two holes 12, in described hole 12, be equipped with end 10, end 10 is provided with axle 4, on described axle 4, cover has spring 5, described spring 5 is positioned at described axle 4 one end near described end, described axle is provided with screw thread 11 away from one end of described end 10, coupling nut 3 on described screw thread 11, described switch operating mechanism 7 is handle type or push button, in described switch operating mechanism, the position of corresponding described end 10 is provided with salient point 8, in described switch, corresponding described nut 3 is provided with two contact points 9.
Under non operating state, switch operating mechanism is through shell cover, and two salient point contacts with end respectively, the nut at axle top be positioned at contact point under, nut and contact point are in separated position, switch is in its unaccessed state; Under operating state, the salient point on switch operating mechanism promotes end and up moves, and end drives axle to move upward, the contact point in the nut touching switch on axle, and switch is in on-state.
The purpose of this utility model, feature and advantage, in connection with embodiment, are further described with reference to accompanying drawing.To contribute to understand the utility model by embodiment, but not limit content of the present utility model.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model, all should think protection range of the present utility model.
