Description
Technical fieldThis utility model relates to a kind of explosion-proof control button.
Background technologyIn the prior art, explosion-proof control button substantially uses INCREASEDSAFETY structure, inapplicable I class hazardous area.The shell of INCREASEDSAFETY structure, only has barrier propterty, in the case of having an accident, shell can not bear the impulsive force produced because of internal explosion, easily causes propagation of explosion rather than flame proof, and then cause on-the-spot subsequent explosion accident, use this product, leave the hidden danger of safety in production to user.
Utility model contentThe purpose of this utility model is: solve the deficiencies in the prior art, discharges the hidden danger in safety in production.
The technical solution of the utility model is such that it and includes mounting jaw, button housing, explosion-proof button movement, button cap, button set, preventing rubber cap, spring, push rod, cable entry, it is characterized in that: in the middle part of button cap 4, outside explosion-proof button movement 3, button set 5 is installed, outside button set 5, is cased with preventing rubber cap 6；Inside button set 5, copper sheathing 10, push rod 8 and spring 7 are installed.
Provide the benefit that: double-layer seal is protected, explosion insulation performance is excellent, durable in use.
Accompanying drawing explanationFig. 1 is front view of the present utility model, and Fig. 2 is the A-A face revolved sectional view of Fig. 1.
Each parts description of symbols in figure: 1. mounting jaw, 2. button housing, 3. explosion-proof button movement, 4. button cap, 5. button set, 6. preventing rubber cap, 7. spring, 8. push rod, 9. cable entry, 10. copper sheathing.
Detailed description of the inventionIn order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further described.
This utility model is a kind of improvement on the basis of prior art, wherein: mounting jaw 1, button housing 2, explosion-proof button movement 3, button cap 4, button set 5, push rod 8, cable entry 9 are same as the prior art.Improvement is embodied in: in the middle part of button cap 4 outside each explosion-proof button movement 3, button set 5 is installed, connected mode is that screw thread adds fluid sealant connection alive, it is cased with preventing rubber cap 6 outside button set 5, the profile of preventing rubber cap 6 is overlapped the profile of 5 right-hand members and is matched with button, play insulating effect, as shown in Figure 2；Inside button set 5, copper sheathing 10, push rod 8 and spring 7 are installed.Copper sheathing 10 plays guiding, wear-resisting effect, and push rod 8 effect is to be increased by original push rod, and spring 7 plays the effect of auxiliary reset.
