Description
Technical field
The utility model relates to technical field of electric equipment, particularly flame-proof switch.
Background technology
In coal mining work, due to the particularity of its operational environment, all electric equipments and switch all need, for antiknock device, to reduce the probability of happening of accident with this.But current flame-proof switch also exists certain deficiency, as complex structure makes workman easily produce faulty operation etc.
Utility model content
The defect above-mentioned for prior art and problem, the utility model provides a kind of flame-proof switch, can effectively prevent workman's faulty operation.
In order to achieve the above object, the utility model provides following technical scheme:
A kind of flame-proof switch comprises: explosion-proof shell, Explosion-proof cap, switch main body, shift knob 3, compressing tablet, safety lock, incoming line, line outlet.Described switch main body is arranged in explosion-proof shell, explosion-proof shell and Explosion-proof cap form cavity by screw rod is fixing, explosion-proof shell two ends arrange line outlet and incoming line, described shift knob is arranged on Explosion-proof cap, shift knob is contacted with switch main body by the through hole on explosion-proof shell, described compressing tablet is pressed on shutdown switch, and one end is fixed by screw rod, and one end is fixed by safety lock.
This flame-proof switch, described compressing tablet mid portion is V-shape.
The beneficial effects of the utility model are: the switch that the utility model is announced, and reasonable in design, particularly shutdown switch has installed compressing tablet and safety lock, effectively prevents workman's faulty operation.
In order to further understand feature of the present utility model and technology contents, refer to following about detailed description of the present utility model and accompanying drawing, but accompanying drawing only provide reference and explanation use, is not used for being limited the utility model.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, by describing in detail embodiment of the present utility model, will make the technical solution of the utility model and other beneficial effect apparent.
Fig. 1 is the utility model flame-proof switch A-A schematic diagram;
Fig. 2 is the utility model flame-proof switch side schematic view.
Embodiment
For further setting forth the technological means and effect thereof that the utility model takes, be described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.
Refer to Fig. 1, the utility model provides a kind of flame-proof switch, comprising: explosion-proof shell 1, Explosion-proof cap 2, switch main body, shift knob 33, compressing tablet 4, safety lock 5, incoming line 6, line outlet 7.Described switch main body is arranged in explosion-proof shell 1, explosion-proof shell 1 forms cavity with Explosion-proof cap 2 by screw rod is fixing, explosion-proof shell 1 two ends arrange incoming line 6 and line outlet 7, described shift knob 3 is arranged on Explosion-proof cap 2, shift knob 3 is contacted with switch main body by the through hole on explosion-proof shell 2, and described compressing tablet mid portion is V-shape, and the vertex (vertices) place of its V word is pressed on shutdown switch, one end is fixed by screw rod, and one end is fixed by safety lock 5.Described safety lock has corresponding key, when needs console switch, after first opening safety lock with key, is removed by compressing tablet, both can split and put line operate into.
In sum, the flame-proof switch that the utility model is announced, reasonable in design, particularly shutdown switch has installed compressing tablet and safety lock, effectively prevents workman's faulty operation.
The above; be only embodiment of the present utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection range of the present utility model.Therefore, protection range of the present utility model should described be as the criterion with the protection range of claim.
