The following will focus on the half-row switching principle of the present invention, the lower end of the pressure rod 3 is pushed by the rolling friction mode of the pushing member 4 horizontally translates, and the following detailed description of the present invention is made by combining the accompanying drawings 3 to 10.

An embodiment: the lower end of the pressure lever 3 pushes the pushing piece 4 to transversely translate in a rolling friction mode. The contact end 42 is rotatably connected with the center of the rolling wheel 10, the lower end of the pressure lever 3 is an inclined surface 32, the inclined surface 32 is abutted against the rolling wheel 10 and is not on the same axis, and when the half-row button 1 is pressed down to drive the pressure lever 3 to move downwards, the inclined surface 32 of the pressure lever 3 and the rolling wheel 10 generate rolling friction to drive the pushing member 4 to move transversely.

As shown in fig. 3 and 5, the working principle of the half-exhaust gas according to an embodiment of the present invention is:

the half-row button 1 is pressed down to drive the pressure lever 3 to move downwards, under the action of friction force, the inclined plane 32 of the pressure lever 3 starts to drive the rolling wheel 10 to roll, the stress condition of the rolling wheel 10 is shown in fig. 4, wherein F1 is resultant force, F2 is horizontal component force, F3 is vertical component force, the horizontal component force F2 pushes the rolling wheel 10 to move transversely along the inclined plane 32, along with the continuous downward movement of the pressure lever 3, the rolling wheel 10 is separated from the inclined plane 32 and then pushes the rolling wheel 10 and the pushing member 4 to move transversely integrally, so that the translation end 41 of the pushing member 4 is driven to block the full-discharge vent 831, the switching spring 7 is compressed, the half-row sealing member 6 slides in the communication cavity 83 in a sealing manner to generate compressed air, namely, the primary air supplement, the compressed air completes the half-discharge from the half-discharge vent 832, besides the primary air supplement, the utility model also designs a secondary air supplement, the top, the full-discharge button 91 extends to form a lower stepped flange 911 abutted against the lower portion of the upper stepped flange 31, when the half-discharge button 1 is pressed down to drive the pressing rod 3 to move downwards, the pressing rod 3 abuts against the full-discharge button 91 to press downwards together, therefore, when the translation end 41 moves transversely, the flange sealing member 5 moves transversely together, so that the sealing at the inner flange 833 disappears, under the condition that the full-discharge vent 831 is blocked, compressed air formed in the full-discharge mounting cavity 81 flows to the half-discharge vent 832, the half-discharge vent 832 is subjected to secondary air supplement, and sufficient air can be discharged from the half-discharge vent 832 finally by combining with the primary air supplement, so that full-half switching air discharge is realized, and the half-discharge vent 832 is ensured to have sufficient air sources. After the complete half-row of button switches, unclamp half-row button 1, half-row spring 2 drives depression bar 3 and half-row button 1 and resets to the original place again under the effect of elastic force, and half-row button 1 exposes in body 8 again, because what this embodiment adopted is the rolling friction structure of face with the face, so frictional force is very little to guaranteed half-row spring 2 and can reset to the right place at every turn, also improved the life of spring simultaneously. After the pressure lever 3 is reset, the switching spring 7 drives the pushing piece 4 to reset transversely under the action of elasticity, the rolling wheel 10 is abutted against the inclined plane 32 at the lower end of the pressure lever 3 again, and the full exhaust vent 831 is unsealed along with the full exhaust vent 831.

The rolling wheel is a round wheel capable of rotating 360 degrees.

As shown in fig. 3, the pneumatic control button of the present invention is designed with an external thread on the outer side of the body 8 to connect with the spiral snap ring 100, and as shown in fig. 10, the pneumatic control button of the present invention is installed in the pre-embedded casing 200 in a snap-fit manner. Can make according to the mounting means of above-mentioned two kinds of differences the utility model discloses install more nimble.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the design of the present application, and all equivalent changes made according to the design key of the present application fall within the protection scope of the present application.
