Description
Technical Field
[0001] The utility model relates to the technical field of air tightness detection equipment, in particular to a multi-purpose air tightness detection device. Background Art
[0002] Airtightness testing equipment is a special equipment used to test the airtightness of objects. It uses air pressure to conduct water-free and non-destructive sealing tests on products. It evaluates the airtightness of objects by measuring the pressure change or leakage of objects under specific air pressure. This equipment is widely used in many industries such as the automotive industry, electronics industry, medical equipment industry, communications and digital industry, and die casting industry.
[0003] There are many types of air tightness testing equipment, such as pressure testing instruments, leakage detection instruments, and air tightness testing devices. When performing air tightness testing on dual-channel components such as pipe fittings or valve bodies, two sealing plugs are respectively fixed on one end of the component to be tested, and high-pressure gas is injected into the internal cavity of the component with the help of external air compression equipment to test the air tightness of the component. However, when performing air tightness testing on dual-channel components such as pipe fittings or valve bodies, due to the various structural dimensions of the components, when the component to be tested is placed on a support frame and clamped with two sealing plugs, the air outlet of the sealing plug cannot be effectively placed in the internal cavity of the component to be tested, so that the component needs to be held manually and the two sealing plugs are controlled by a cylinder to clamp the component. This increases the difficulty of operation for operators when testing some components with a certain weight. Utility Model Content

DETAILED DESCRIPTION
[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0019] like Figure 1-Figure 3As shown, the utility model provides a multi-purpose air tightness detection device, including a base 1, a first mounting seat 2 is fixedly installed on one side of the base 1, a second mounting seat 3 is fixedly installed on the other side of the base 1, a guide rail 4 is also fixedly installed on the base 1 located on one side of the first mounting seat 2, a slider 7 is slidably installed on the guide rail 4, a cylinder 5 is fixedly installed on the side of the first mounting seat 2 away from the guide rail 4, the cylinder 5 is connected to an external pump station through an air pipe, a third mounting seat 6 is fixedly installed on the output end of the cylinder 5, a first sealing seat 8 is fixedly installed on the third mounting seat 6 on a side relative to the second mounting seat 3, and a second sealing seat 9 is fixedly installed on the side of the second mounting seat 3 relative to the first sealing seat 8, An air inlet nozzle 10 is fixedly installed on the outer side of the second sealing seat 9, and the air inlet nozzle 10 is connected to an external air compression device through a pipeline. An air outlet 11 is opened at the center position inside the second sealing seat 9, and the air outlet 11 is connected to the air inlet nozzle 10 channel. A support 12 is arranged on the base 1 between the first sealing seat 8 and the second sealing seat 9, and the support 12 includes two fixed seats 13, and the fixed seats 13 are fixedly installed on the base 1. Support seats 14 are movably installed on the two fixed seats 13 respectively, and telescopic rods 22 are fixedly installed at the center position of the lower ends of the two support seats 14, a connecting rod 15 is movably installed between the two telescopic rods 22, and two adjustment sleeve rods 16 are movably installed on the outer side of the connecting rod 15.
[0020] like Figure 2-Figure 3 As shown, two limit rods 17 are fixedly installed on the upper end of the fixed seat 13, a telescopic slot 18 is provided at the center position of the fixed seat 13, and two slide grooves 19 are provided inside the telescopic slot 18. The second mounting seat 3 located on both sides of the slide groove 19 is also provided with a plurality of card slots 20. The provision of the telescopic slot 18 can provide stable conditions for the telescopic movement of the telescopic rod 22, and the provision of the card slot 20 can provide conditions for the clamping and limiting of the adjustment sleeve rod 16. Limit slots 21 are provided on both sides of the supporting seat 14, and a slot 23 is provided at the lower end of the telescopic rod 22. The telescopic rod 22 is inserted and installed in the telescopic slot 18, and the two limit slots 21 are respectively inserted and installed on the corresponding limit rods 17. The supporting seat 14 is movably installed on the fixed seat 13 through the telescopic rod 22 and the limit slot 21, so that the lifting and lowering of the supporting seat 14 can be more stable.
[0021] like Figure 1-Figure 3As shown, both ends of the connecting rod 15 pass through the corresponding slide grooves 19 and are inserted into the slots 23 of the corresponding telescopic rods 22, and the connecting rod 15 located in the slots 23 is also fixed by screws, and the two adjusting sleeves 16 are fixedly installed with shift blocks 24 on the opposite sides, and the two adjusting sleeves 16 are fixedly installed with two clamping blocks 25 on the sides away from the shifting blocks 24, respectively. The adjusting sleeves 16 and the shifting blocks 24 are inserted and installed on the outside of the connecting rod 15, and the connecting rod 15 located between the two shifting blocks 24 is sleeved with a compression spring 26, and the clamping block 25 is inserted and installed in the corresponding clamping groove 20. The heights of the two supporting seats 14 can be synchronously adjusted through the connecting rod 15, and the adjustment position of the telescopic rod 22 is limited by means of the two adjusting sleeves 16, thereby fixing the adjustment height of the supporting seat 14.
[0022] It should be noted that the utility model is a multi-purpose air tightness detection device. Before detecting different batches of parts, the heights of the two supporting seats 14 can be adjusted according to the size of the parts. For example, when the longitudinal cross-sectional size of the parts is small and they are placed on the two supporting seats 14 and the port on one side of the parts cannot wrap the air outlet 11 inside, the two third mounting seats 6 can be held in one hand, and the two shifting blocks 24 can be pressed relative to each other, so that the two shifting blocks 24 respectively drive the corresponding adjusting sleeve rods 16 to move to one side on the connecting rod 15, and at the same time, the two shifting blocks 24 compress the compression springs 26, so that the two adjusting sleeves 16 are moved to one side. The two blocks 25 on the other side of the rod 16 are disengaged from the corresponding slots 20. At this time, the connecting rod 15 can be lifted up by hand force in cooperation with the two adjusting sleeve rods 16. Thus, the connecting rod 15 drives the corresponding supporting seat 14 to move up synchronously through the two telescopic rods 22. When the two supporting seats 14 move up synchronously to the required height, the force can be released by fingers, so that the rebound force of the compression spring 26 pushes the two adjusting sleeve rods 16 to move oppositely outside the connecting rod 15, thereby making the block 25 on one side of the adjusting sleeve rod 16 snap into the corresponding slot 20, so that the telescopic rod 22 can be limited, and then the height of the supporting seat 14 can be limited.
[0023] Subsequently, the components can be placed on the two supporting seats 14, and the cylinder 5 can be started through an external controller so that the output end of the cylinder 5 pushes the first sealing seat 8, and then the components are clamped with the help of the first sealing seat 8 and the second sealing seat 9. Subsequently, the external air compression equipment is started to inject high-pressure gas into the components and maintain it for a certain period of time. If the pressure displayed by the external controller does not change, it proves that there is no leakage in the components.
[0024] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
