Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0020] Embodiment 1

[0021] Please refer to Figures 1-4 The utility model provides a kind of air cylinder gas leak detection equipment, including water tank 1, the front side of water tank 1 is provided with observation window 2, the inside corner of water tank 1 is provided with four fixed blocks 3, fixed block 3 is located above the edge line of water tank 1, and guide rod 13 is arranged between fixed block 3 and water tank 1, and one of guide rod 13 is threaded rod, the threaded rod passes through fixed block 3 and extends one end upwards, the top of water tank 1 is provided with lifting motor 4 connected with threaded rod;

[0022] As shown in Figure 1 The rear end of water tank 1 is fixed with support plate 5, the top end of support plate 5 is fixed with air pump 6, two air hoses 7 are connected on air pump 6, air hose 7 is connected with air cylinder 8, and one of air hose 7 is air inlet pipe, another air hose 7 is air outlet pipe, so as to inflate and exhaust air cylinder 8.

[0023] As shown in Figure 1 The outside of guide rod 13 is provided with U-shaped frame 16, two U-shaped frames 16 are located at the two sides of observation window 2, a plurality of support rods 15 are arranged between two U-shaped frames 16, air cylinder 8 is placed on the top of support rod 15, and guide groove 14 is formed on the two support rods 15 outside;

[0024] As shown in Figure 1 And Figure 2As shown, two movable sliders 10 are provided inside the guide groove 14, and two rollers 11 are provided on the outside of the movable sliders 10. The rotating shafts of the rollers 11 are fixedly connected to the movable sliders 10. After the movable sliders 10 are inserted into the guide groove 14, the rollers 11 will contact the top surface of the support rods 15. At this time, the bottom surface of the movable slider 10 coincides with the bottom surface of the support rods 15, and a limit block 12 is fixedly connected to the bottom of the movable slider 10. A U-shaped fixing bar 9 is fixed to the top of the two movable sliders 10, and the U-shaped fixing bar 9 spans over the multiple support rods 15.

[0025] Specific working principle:

[0026] Before conducting a sealing test on the air cylinder 8, the other outlets of the air cylinder 8 are blocked, and the two air delivery hoses 7 are connected to the air inlet and air outlet of the air cylinder 8. The U-shaped fixing bar 9 is moved so that the U-shaped fixing bar 9 spans over the cylindrical part of the air cylinder 8, and the lifting motor 4 is started. The support rod 15 is driven downward by the lifting motor 4, and at the same time, the U-shaped fixing bar 9 is limited so that the U-shaped fixing bar 9 drives the air cylinder 8 to be immersed in water. Then the air pump 6 is started to inflate the air cylinder 8 to increase the air pressure inside the air cylinder 8. Whether there are bubbles is observed through the observation window 2. At the same time, due to the increase in the air pressure of the air cylinder 8, whether there is a leak can be observed more quickly.

[0027] Example 2

[0028] The difference between this embodiment and embodiment 1 is that Figures 3-4 As shown, a fixing belt 17 is provided between the two movable sliders 10, one end of the fixing belt 17 is fixedly connected to the top of the movable slider 10, the other end of the fixing belt 17 passes through the movable slider 10, and a lock buckle 19 is fixed to the front end of the movable slider 10, the fixing belt 17 passes through the lock buckle 19, and the fixing belt 17 is locked and fixed by the lock buckle 19, and an elastic elastic belt 18 is fixed between the fixing belt 17 and the U-shaped fixing strip 9, and the fixing belt 17 can be reset by the elastic elastic belt 18, so that when the U-shaped fixing strip 9 is moved to the top of the gas cylinder 8, the fixing belt 17 will not be hung on the gas cylinder 8 and affect the movement of the U-shaped fixing strip 9.

[0029] Specific working principle:

[0030] After the U-shaped fixing strip 9 is moved above the gas cylinder 8, the fixing belt 17 is pulled to pass through the inside of the movable slider 10 and fixed by the lock buckle 19. During this process, the fixing belt 17 is tied to the outside of the gas cylinder 8, pressing the gas cylinder 8 against the top of the support rod 15, thereby fixing the gas cylinder 8 and making the gas cylinder 8 more stable during the immersion test.

[0031] When the gas cylinder 8 needs to be taken out, the lock 19 no longer fixes the fixing belt 17, at this time the elastic band 18 reversely pulls the fixing belt 17 to reset the fixing belt 17.

[0032] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application.
