[0027] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] Example 1: Figure 1-5 As shown, the utility model provides an electronic water pump air tightness detection device, comprising a body 1 and a connecting mechanism arranged inside the body 1, wherein the connecting mechanism comprises a pressurizing component, a clamping component and a sealing component;

[0029] The pressurizing component includes an air tank 2, an air delivery pipe 3, an air delivery pump 4, a pressurizing pipe 5 and an exhaust pipe 6. The air tank 2 is welded inside the body 1, and one end of the air tank 2 is sealedly connected to the air delivery pump 4 through the air delivery pipe 3. The air delivery pipe 3 arranged at one end of the air delivery pump 4 away from the air tank 2 passes through the side wall of the body 1, and the top of the air tank 2 is sealedly connected to the pressurizing pipe 5 and the exhaust pipe 6. When working, by setting the air tank 2, the air delivery pipe 3, the air delivery pump 4, the pressurizing pipe 5 and the exhaust pipe 6, the air delivery pump 4 starts to work and delivers gas to the inside of the air tank 2 through the air delivery pipe 3. After the inside of the air tank 2 reaches a certain pressure, the air delivery pump 4 stops working, and the air tank 2 delivers gas to the pressurizing pipe 5 for pressurization, thereby realizing the control operation of the pressurization detection test pump 8 for air tightness;

[0030] The clamping assembly includes a test lower mold 7, a test pump 8, a water pump outlet pipe 9, a spring rope 10, a main cylinder 11, a sleeve 12, a spring clip 13 and a U-shaped pad 14. The test lower mold 7 is fixedly installed on the upper surface wall of the body 1, and a test pump 8 is arranged inside the test lower mold 7. The water pump outlet pipe 9 is arranged at both ends of the test pump 8. The main cylinder 11 is fixedly installed inside the test lower mold 7 through a spring rope 10. Two groups of spring ropes 10 are arranged. A sleeve 12 is arranged on the outer wall of the main cylinder 11. A spring clip 13 is welded on the outer wall of the sleeve 12. The test pump 8 is fixedly installed inside the test lower mold 7. U-shaped pads 14 are provided on both sides. When working, the spring rope 10, the main tube 11, the sleeve 12, the spring clip 13 and the U-shaped pad 14 are provided, which is conducive to the sleeve 12 extending to completely contact the water pump outlet pipe 9. The two sets of sleeves 12 can completely seal the two sets of water pump outlet pipes 9 on the test pump 8 to ensure that the inside of the test pump 8 is completely sealed. Then, the water pump outlet pipe 9 on the test pump 8 is pushed against the rubber cushion 21, and the spring clip 13 is opened, so that the spring clip 13 clamps and fixes the water pump outlet pipe 9 to prevent the water pump outlet pipe 9 from shaking inside the test lower mold 7;

[0031] Furthermore, the top ends of the pressure pipe 5 and the exhaust pipe 6 both pass through the top of the machine body 1 and are arranged inside the test lower mold 7. During operation, by setting the pressure pipe 5 and the exhaust pipe 6, the pressure pipe 5 can transport gas into the test lower mold 7 for pressurization. After the test is completed, the pressurized gas is recovered into the gas storage tank 2 through the exhaust pipe 6, thereby saving energy and reducing costs.

[0032] Furthermore, a tension spring 17 is provided inside the main tube 11, one end of the tension spring 17 is fixedly installed on the bottom of the main tube 11, and the other end of the tension spring 17 is fixedly installed on the inner top of the sleeve 12, and one end of the spring rope 10 is welded to the outer bottom of the main tube 11. During operation, by arranging the spring rope 10 and the tension spring 17, the spring rope 10 is conducive to the main tube 11 not being separated from the inside of the test mold 7, and the tension spring 17 can be stretched to a certain length, so as to realize the airtightness detection of electronic air pumps of different sizes and lengths, and has a wider range of applications.

[0033] Furthermore, an air pressure detection sensor 18 arranged on one side of the main cylinder 11 is fixedly installed inside the test lower mold 7. When working, by setting the air pressure detection sensor 18, the gas storage tank 2 delivers gas to the test lower mold 7 for pressurization, and the pressurization is stopped after a certain period of time. The air tightness of the test pump 8 can be judged by observing the air pressure change of the air pressure detection sensor 18 within a period of time.

[0034] Furthermore, one end of the U-shaped pad 14 away from the test pump 8 is welded to the main shaft of the electric push rod 19, and an anti-skid pad 20 is fixedly installed on the U-shaped pad 14. The electric push rod 19 is arranged at the upper surface wall of the body 1, and the main shaft of the electric push rod 19 passes through the side wall of the test lower mold 7. During operation, by setting the U-shaped pad 14 and the anti-skid pad 20, the U-shaped pad 14 can pressurize and fix the test pump 8 to prevent the test pump 8 from shaking during the test, and the anti-skid pad 20 ensures that the U-shaped pad 14 is more stable during the clamping process to avoid sliding, thereby ensuring the accuracy of the test.

[0035] Furthermore, a rubber pad 21 is fixedly installed at one end of the sleeve 12 away from the main tube 11. During operation, the rubber pad 21 is provided to facilitate the water pump outlet pipe 9 to be completely close to the sleeve 12, so that the water pump outlet pipe 9 does not leak, thereby ensuring the accuracy of the test pump 8 during the test process.

[0036] Furthermore, vertical guide rods 22 are welded on the left and right side walls of the body 1, and a lifting cylinder 23 is fixedly installed on one end of the vertical guide rod 22 away from the body 1. The main shaft of the lifting cylinder 23 is fixedly installed on the upper surface wall of the test upper mold 16. When working, the lifting cylinder 23 is set to pressurize the test upper mold 16, so that the test upper mold 16 is completely close to the test lower mold 7, ensuring that a closed space is reached during the pressurized test, and the detection is more accurate.

[0037] Example 2: Figure 1-5 As shown, an electronic water pump air tightness detection device proposed by the utility model, compared with Example 1, as another implementation of the utility model, the sealing assembly includes a sealing gasket 15 and a test upper mold 16, the top of the test lower mold 7 is fixedly installed with a sealing gasket 15, and the test upper mold 16 is arranged above the sealing gasket 15. When working, by setting the sealing gasket 15, it is conducive to the test upper mold 16 to be completely close to the test lower mold 7, and there is no gap between the test upper mold 16 and the test lower mold 7, thereby achieving the effect of a closed space.

[0038] During operation, first place the test pump 8 inside the test lower mold 7, and the electric push rod 19 starts working. The U-shaped pad 14 is driven by the main shaft to squeeze and fix the test pump 8. The anti-slip pad 20 can prevent the test pump 8 from shaking during the air tightness detection process, which is safer and more reliable. Then stretch the sleeve 12 so that the sleeve 12 is stretched on the main cylinder 11 through the tension spring 17. The sleeve 12 extends to completely contact the water pump outlet pipe 9. Then, the water pump outlet pipe 9 on the test pump 8 is pushed against the rubber cushion 21, and the spring clip 13 is opened so that the spring clip 13 clamps and fixes the water pump outlet pipe 9 to prevent the water pump outlet pipe 9 from shaking inside the test lower mold 7.

[0039] Next, the lifting cylinder 23 starts to work, and the main shaft of the lifting cylinder 23 moves downward, so that the test upper mold 16 and the test lower mold 7 are completely fitted together. The sealing gasket 15 on the test lower mold 7 ensures that there is no gap between the test upper mold 16 and the test lower mold 7, ensuring stronger sealing during the pressurization process.

[0040] Finally, the air pump 4 starts working and delivers gas to the interior of the gas tank 2 through the air pipe 3. After the interior of the gas tank 2 reaches a certain pressure, the air pump 4 stops working, and the gas tank 2 delivers gas to the pressurizing pipe 5 for pressurization. The pressurization is stopped after a certain period of time. The air tightness of the test pump 8 can be judged by observing the change in air pressure within a period of time in the air pressure detection sensor 18. After the test is completed, the pressurized gas is recovered into the gas tank 2 through the exhaust pipe 6, saving energy and reducing costs.

[0041] Finally, it should be noted that the above are only preferred embodiments of the utility model and are not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
