Abstract
The utility model discloses a pneumatic-control reset type button switch which comprises a shell; a movable contact and a static contact are arranged in the shell; a button is arranged on the shell; a pneumatic cylinder is also arranged on the shell; the button is provided with a piston rod which is movably arranged in the pneumatic cylinder; the bottom of the piston rod is provided with a sealing gasket; the top of the pneumatic cylinder is provided with a sealing cover; and the piston rod penetrates through the sealing cover and is arranged between the sealing cover and the pneumatic cylinder. The pneumatic-control reset type button switch is simple in structure and is provided with the pneumatic cylinder; the piston rod is arranged on the button, when in use, the button is pressed down, the button drives the piston rod in the cylinder moving pressure; when the pneumatic-control reset type button switch is in use, the button is pressed so that the button drives the piston rod to move in the pneumatic cylinder, and the piston rod compresses air in the pneumatic cylinder; since the air in the pneumatic cylinder is compressed, the pressure of the compressed air is greater than that of external air; when the button is loosened, the compressed gas in the pneumatic cylinder resets to drive the piston rod to reset, and then the button resets; and the pneumatic-control reset type button switch is convenient in use, good in use stability, high in practicability, and good in practicality.
Description
Technical field
The utility model belongs to push-button switch technical field, is specifically related to a kind of Pneumatic resetting type push-button switch.
Background technology
The push-button switch of prior art is generally to reset by back-moving spring, although it can realize push-button switch control action, yet, while using for a long time due to back-moving spring, the elastic force of spring can die down gradually, can affect to a certain extent the normal use of push-button switch, and use back-moving spring to be also easier to break down, also can affect to a certain extent the stability in use of push-button switch, simultaneously, spring compression elasticity owing to pressing is larger, also be easier to make back-moving spring lose reset function, also can affect to a certain extent the stability of push-button switch, applicability is restricted to a certain extent, practicality is difficult to meet the needs of people's life.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, convenient to use and Pneumatic resetting type push-button switch that stability in use is good.
The technical scheme that realizes the utility model object is a kind of Pneumatic resetting type push-button switch, comprise housing, in described housing, be provided with moving contact and fixed contact, described housing is provided with button, on described housing, be also provided with air pressure cylinder, described button is provided with the piston rod being movably arranged in described air pressure cylinder, the bottom of described piston rod is provided with sealing gasket, top at described air pressure cylinder is provided with seal cover, described piston rod through described seal cover and be arranged on described seal cover and described air pressure cylinder between.
Also comprise seal protection layer, described seal protection layer is arranged on described air pressure cylinder inner wall.
Described sealing gasket is soft sealing pad.
The utlity model has positive effect: of the present utility model simple in structure, be provided with air pressure cylinder, on button, be provided with piston rod, in use, push button, button drives piston rod to move in air pressure cylinder, the gas in piston rod compression gas-pressure cylinder now, because the gas in air pressure cylinder is compressed, therefore its pressure is greater than the pressure of extraneous air, when release button, Compressed Gas in air pressure cylinder resets, drive piston rod resets, and then make to drive push-button reset, it is convenient to use, and stability in use can be good, practicality is stronger, and provide cost savings to a certain extent, practicality is good.
Accompanying drawing explanation
For content of the present utility model is more likely to be clearly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail below, wherein:
Fig. 1 is structural representation of the present utility model.
Embodiment
(embodiment 1)
Fig. 1 has shown a kind of embodiment of the present utility model, and wherein Fig. 1 is structural representation of the present utility model.
See Fig. 1, a kind of Pneumatic resetting type push-button switch, comprise housing 1, in described housing 1, be provided with moving contact 2 and fixed contact 3, described housing 1 is provided with button 4, on described housing 1, be also provided with air pressure cylinder 5, described button 4 is provided with the piston rod 6 being movably arranged in described air pressure cylinder 5, the bottom of described piston rod 6 is provided with sealing gasket 7, at the top of described air pressure cylinder 5, be provided with seal cover 8, described piston rod 6 through described seal cover 8 and be arranged on described seal cover 8 and described air pressure cylinder 5 between.Be provided with air pressure cylinder, on button, be provided with piston rod, in use, push button, button drives piston rod to move in air pressure cylinder, and the gas in piston rod compression gas-pressure cylinder now, because the gas in air pressure cylinder is compressed, therefore its pressure is greater than the pressure of extraneous air, when release button, the Compressed Gas in air pressure cylinder resets, and drives piston rod to reset, and then make to drive push-button reset, it is convenient to use, and stability in use can be good, and practicality is stronger, and provide cost savings to a certain extent, practicality is good.
Also comprise seal protection layer 9, described seal protection layer 9 is arranged on described air pressure cylinder 5 inwalls.
Described sealing gasket 7 is soft sealing pad.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all execution modes.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection range of the present utility model.
