Description
Technical field
The utility model relates to the electrical instrumentation device, and more particularly, the utility model relates to a kind of shift knob mechanism of electrical instrumentation.
Background technology
Existing electrical instrumentation; Often be in high humidity, the high quick-fried operational environment, still, the housing of traditional electrical instrumentation does not have explosion-proof water-proof function or its explosion-proof water-proof function is relatively poor; For this reason, be necessary for the guard shield that traditional electrical instrumentation installs explosion-proof waterproof in addition additional.Yet; In order to operate normally; Operating personnel must operate the electrical instrumentation of generally installing or add various push-button switches, sensitive switch in it on guard shield, therefore, on the guard shield indirect switching mechanism with explosion-proof water-proof function must be installed.But the indirect switching mechanism on traditional guard shield all only has individual event waterproof or explosion prevention function, and traditional protective indirect switching mechanism volume big, be knob, underaction, quick also is not suitable for miniaturization during use.
Summary of the invention
To the above-mentioned shortcoming of prior art, the purpose of the utility model is the indirect button mechanism that a kind of explosion-proof waterproof will be provided, and it has stronger explosion-proof water-proof function concurrently, flexible operation, quick and easy to assembly, and advantages of small volume, easy to utilize.
For this reason; The technical solution of the utility model is a kind of indirect button mechanism of explosion-proof waterproof; This button mechanism comprise the top button cover, be connected the push rod of button cover bottom; And said button cover comprises protruding back-up ring, and said push rod comprises boss, and clamping has the elastomeric pad of explosion-proof waterproof between push rod boss upper end and button cover lower end; Said button mechanism also comprises the seat of honour and following and a following nut through being threaded; The above button cover of back-up ring is slidingly fitted in the perforate of the seat of honour, and the push rod below the boss is slidingly fitted in down in the block hole, and the periphery of said elastomeric pad is clamped between the seat of honour and following the relative anchor ring simultaneously.
The indirect button mechanism of the explosion-proof waterproof of the utility model adopts the seat of honour and following and a following nut that are threaded, thereby is easy to be installed in following more hermetically on the guard shield with the seat of honour through following nut, and assembling easily; And the structure of the explosion-proof water-proof elastic pad of clamping between push rod boss upper end and the button cover lower end, the periphery that adds elastomeric pad are clamped in the reinforced seal structure between the seat of honour and following the relative anchor ring simultaneously; Make the explosion-proof water-proof function of the indirect button mechanism of the utility model obtain jointly to improve; And this characteristic structure has also realized the function of push switch: touch the button instantly when covering, the silica gel material elastomeric pad that is clamped between push rod boss upper end and the button cover lower end also can be out of shape (referring to Fig. 2); When reaching predetermined stroke; The switch opens of instrument appliance within the guard shield, instrument appliance is started working, because the characteristic of elastomeric pad silica gel material; The stroke of switch push rod receives elastic limit, can prevent effectively that internal switch is impaired; Behind the release button lid, under the effect of elastomeric pad resilience force, the button cover homing.Therefore visible, the utility model flexible operation, quick and volume miniaturization more, easy to assembly, be more convenient for applying.
For further improving the explosion-proof water-proof function by indirect button mechanism, the utility model also comprises following improvement:
Also be provided with elastic seal ring between a said following lower end and the following nut.
Interconnect through helicitic texture between said button cover and the push rod, said push rod boss is located at the lower end of helicitic texture.
Helicitic texture between button cover and the push rod can increase push rod boss upper end and the clamping strength of button cover lower end for elastomeric pad, and assemble more convenient.
The upper and lower surfaces of said elastomeric pad is respectively equipped with the upper and lower bulge loop of reinforced seal.The upper and lower bulge loop of corresponding said elastomeric pad, said button cover lower surface and/or boss upper surface are provided with scrobicular ring.
The upper and lower bulge loop of the upper and lower surfaces of elastomeric pad; And the scrobicular ring of button cover lower surface and/or boss upper surface; Can further increase the sealing property under deformation condition between elastomeric pad and button cover, the boss, improve the quick-fried water-proof function of anti-the utility model button mechanism.
For further improving operating flexibility, the agility of indirect button mechanism, the utility model also comprises following improvement:
Also be provided with goring push spring between the lower end of said push rod boss and the said following block hole end face.
Goring push spring can be strengthened the travel limits effect of push rod switch, increases the reaction flexibility and the agility of push rod switch.
Through test, the indirect button mechanism classification of waterproof of the explosion-proof waterproof of the utility model reaches IP67; Explosion proof ratings reaches Exd II B.Its explosion-proof performance mainly is the design of following of switch operating mechanism and switch push rod, both plane mating surface length=15.2mm, and following seat and the meshing axial length=11.2mm in the seat of honour, meshing Kou Shuo ≧ 10 all reach explosion proof ratings Exd II B requirement.
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
