[0015] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.
[0016] Combination Figures 1 to 3 A multi-channel air path switching device includes a main body 1, a sliding groove 2 is opened through the left side of the main body 1, an upper air pipe 3 is opened through the top of the main body 1, and a lower air pipe 4 is opened through the bottom of the main body 1. A twitching rod 5 is arranged inside the sliding groove 2, and two sliding blocks 6 are fixedly connected to the outside of the twitching rod 5. A card block 7 is fixedly connected to the right side of the right sliding block 6. Hemispherical grooves 8 are opened on the upper and lower sides of the card block 7. A placement groove 9 is opened on the upper and lower sides of the right side of the sliding groove 2. A spring 10 is fixedly connected to one end of the placement groove 9, and a ball 11 is fixedly connected to one end of the spring 10.
[0017] The cooperation among the spring 10, the ball 11 and the hemispherical groove 8 enables the clamping block 7 to be self-locking, so as to facilitate the switching of the gas path and achieve the purpose of enabling the gas path to be selected.
[0018] Combination Figure 2 and Figure 3 The distance between the sliders 6 is greater than the distance between the lower air pipes 4. When the right lower air pipe 4 is in the open state, the block 7 is in the locked state. The diameter of the hemispherical groove 8 is consistent with that of the sphere 11. The diameter of the sphere 11 is smaller than the diameter of the placement groove 9. The upper air pipe 3 and the lower air pipe 4 are PU material hoses, and the main body 1 is made of aluminum alloy.
[0019] By making the distance between the sliders 6 greater than the distance between the lower air pipes 4, only one air path is always connected regardless of whether the device is in a self-locking state or an unlocking state.
[0020] Working principle: When in use, connect the lower air pipes 4 to different gases respectively. When the gas on the right side needs to work, push the sliding rod 5 to move to the right, driving the slider 6 to move to the right inside the sliding groove 2. When the clamping block 7 moves to contact the sphere 11, under the action of the thrust, the clamping block 7 squeezes the sphere 11 along the placement groove 9 inward, and the spring 10 is compressed. When the hemispherical groove 8 and the sphere 11 are on the same vertical line, the sphere 11 loses the extrusion, and the spring 10 extrudes the sphere 11 and locks it into the hemispherical groove 8. At the same time, since the distance between the sliders 6 is greater than the distance between the lower air pipes 4, when the lower air pipe 4 on the right side is in a connected state, the lower air pipe 4 on the left side is just in a closed state. When the gas on the left side needs to work, the user pulls the sliding rod 5 to move outward, driving the clamping block 7 to disengage from the sphere 11 to complete unlocking, and at the same time connecting the lower air pipe 4 on the left side and closing the lower air pipe 4 on the right side.
[0021] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
