[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 - Figure 4, an embodiment provided by the present utility model: a valve detection device, including a base 1, a workbench 2 is fixedly connected to the top of the base 1, two sliders 8 are slidably connected to the top of the workbench 2, rubber plugs 22 are fixedly connected to the opposite sides between the two sliders 8, an air valve 13 is fixedly connected to the middle of the right rubber plug 22, a barometer 21 is fixedly connected to the middle of the left rubber plug 22, a valve body 3 is arranged on the top of the workbench 2, support seats 5 are fixedly connected to the tops of both sides of the base 1, an L-shaped rod 6 is rotatably connected inside the support seat 5, a pull rod 7 is arranged between the slider 8 and the L-shaped rod 6, an electric push rod 20 is arranged inside the base 1, the output end of the electric push rod 20 is rotatably connected to the bottom of the left L-shaped rod 6, the right end of the electric push rod 20 is rotatably connected to the bottom of the right L-shaped rod 6, a support rod 17 is fixedly connected to the middle of the L-shaped rod 6, a sleeve 18 is slidably connected inside the base 1, a second rotating rod 19 is arranged between the sleeve 18 and the two support rods 17, a rotating assembly is arranged above the workbench 2, and the rotating assembly is used for detecting the opening and closing of the valve. One end of the pull rod 7 is rotatably connected inside the slider 8, the other end of the pull rod 7 is rotatably connected to the top of the L-shaped rod 6, one end of the second rotating rod 19 is rotatably connected to the outside of the sleeve 18, and the other end of the second rotating rod 19 is rotatably connected to the end of the support rod 17. The opposite sides between the two rubber plugs 22 are both abutted against the two ends of the valve body 3.

[0032] Specifically, in this embodiment, an electric push rod 20 is arranged inside the base 1, and L-shaped rods 6 are rotatably connected to the left and right ends of the electric push rod 20. In order to limit the electric push rod 20, support rods 17 are fixedly connected to the middle of the two L-shaped rods 6. The opposite ends between the two support rods 17 are connected to the sleeve 18 through a second rotating rod 19. The sleeve 18 slides on the outside of a cylinder arranged inside the base 1, so that the electric push rod 20 will not shift when starting. The tops of the two L-shaped rods 6 are rotatably connected to the sliders 8, and the side of the L-shaped rod 6 close to the base 1 is rotatably connected to the support seat 5. In this way, by starting the electric push rod 20, the two sliders 8 can slide towards each other. A valve is placed between the two sliders 8, and rubber plugs 22 are fixed to the opposite sides between the two sliders 8, aiming to seal the valve while clamping the valve body 3. The valve body 3 can be inflated through the air valve 13. After inflation, the pressure inside the valve body 3 can be detected through the barometer 21. After a period of time, read the barometer 21 again and observe whether the reading remains unchanged, so as to judge the airtightness of the valve.

[0033] Refer to Figure 1 - Figure 2, the rotating assembly includes a disc 10. Two main gears 12 are rotatably connected to the top of the disc 10. A plurality of convex columns 11 are fixedly connected to the top of each of the two main gears 12. The two main gears 12 are meshed with each other. A driven gear 14 is rotatably connected to the top of the disc 10. A three-foot member 16 is rotatably connected to the inside of the driven gear 14. A motor 15 is fixedly connected to the bottom of the disc 10. Two first rotating rods 9 are rotatably connected to the bottom of the disc 10. A switch 4 is rotatably connected to the top of the valve body 3. The outside of the three-foot member 16 abuts against the outside of the switch 4. The two ends of the two first rotating rods 9 away from the disc 10 are respectively rotatably connected to the tops of the two sliders 8. The driven gear 14 is located above the two main gears 12. The outer teeth of the driven gear 14 are meshed with the convex columns 11.

[0034] Specifically, when the valve is clamped, the sliding of the slider 8 will cause the first rotating rod 9 to deflect, so that the three-foot member 16 located above the switch 4 will finally get stuck in the middle of the switch 4. After the airtightness test is completed, the motor 15 can be started. Under the action of the motor 15, the two main gears 12 rotate in opposite directions through meshing with each other. There is a driven gear 14 above the two main gears 12. The driven gear 14 is meshed with the convex columns 11 arranged on the top of the main gears 12. At this time, the driven gear 14 is driven to rotate in positive and reverse directions alternately, and the switch 4 is driven to rotate through the three-foot member 16, and the valve is alternately opened and closed to detect the durability of the switch 4 of the valve.

[0035] Working principle: The electric push rod 20 inside the base 1 can drive the two L-shaped rods 6 to rotate. Since the middle of the L-shaped rod 6 is rotatably connected to the support base 5, the electric push rod 20 can control the top of the L-shaped rod 6 by rotating the bottom of the L-shaped rod 6. The top of the L-shaped rod 6 drives the two sliders 8 to slide in opposite or opposite directions through the pull rod 7. The shape of the slider 8 can be stuck in the top chute of the workbench 2. When the electric push rod 20 is started, the two sliders 8 will slide in opposite directions. A rubber plug 22 is fixed at the end of the slider 8. Finally, the valve will be clamped by the two sliders 8 at both ends, and the valve body 3 will be sealed. Air is injected into the valve body 3 through the air valve 13, and the pressure gauge 21 is used to read the pressure inside the valve body 3. After maintaining for a period of time, observe whether the reading of the pressure gauge 21 changes to judge the airtightness inside the valve body 3. When the slider 8 slides, the two first rotating rods 9 rotate, so that the vertical distance between the three-foot member 16 and the switch 4 decreases. It is preset that the three-foot member 16 can just get stuck in the middle of the switch 4. At this time, the motor 15 is started. Since the two main gears 12 are meshed with each other, the two main gears 12 rotate in opposite directions, and the driven gear 14 can be meshed with the convex columns 11 at the tops of the two main gears 12 respectively. Under the action of the two main gears 12 respectively, the driven gear 14 rotates in opposite directions alternately, and the three-foot member 16 drives the switch 4 to rotate, and the valve is constantly opened and closed. The durability of the switch 4 of the valve can be judged through multiple rotations.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
