Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Following example
For this utility model is described, but it is not limited to scope of the present utility model.
As it is shown in figure 1, a kind of explosion proof instrument button assembly device, including instrument 1, housing 2, safety glass 3 and button assembly
4, described instrument 1 is arranged in housing 2, and described instrument 1 is tightly connected with housing 2, on described housing 2 by dial framework 11
Being provided with viewing window 21, described safety glass 3 is arranged between viewing window 21 and gauge outfit 12, and described button assembly 4 is through housing
2 and control button 13 with instrument 1 lean.
As in figure 2 it is shown, described button assembly 4 includes button axle 41, axle sleeve 42, stage clip 43 and V-type elastic sealing element 44,
Described axle sleeve 42 through housing 2 and is tightly connected with housing 2, and described button axle 41 is through axle sleeve 42 control with instrument 1
Button 13 leans, and forms the toroidal cavity 45 being used for installing stage clip 43 closed between described axle sleeve 42 and button axle 41,
Described button axle 41 can under the effect of stage clip 43 the control button 13 of control instrument 1, described V-type elastic sealing element 44
Contact in toroidal cavity 45 and with the inner wall sealing of toroidal cavity 45, and by stage clip 43 apply axial along button axle 41
The power in direction.Further, described button axle 41 near being provided with jump ring 46 between one end of instrument 1 and axle sleeve 42, with prevent by
Key axle 41 departs from axle sleeve 42.By the axle 41 that pushes button, stage clip 43 compresses, and V-type elastic sealing element 44 pressurized is expanded, with
