Description

A multi-channel switching airtightness detection device Technical Field

[0001] This utility model relates to the field of airtightness testing, and more specifically, to a multi-channel switching airtightness testing device. Background Technology

[0002] In related technologies, conventional methods for testing the sealing performance of the tested enclosure include watertightness testing and airtightness testing. Watertightness testing is costly, and water after testing can negatively impact the performance of the enclosure. Therefore, airtightness testing is typically used to test the enclosure.

[0003] Application CN117367708 discloses a multi-channel airtightness testing device and method, belonging to the field of airtightness testing technology. The airtightness testing device includes a support, an inflation assembly, and a detection control assembly. The inflation assembly includes an inlet pipe and multiple branch pipes, each branch pipe being connected to the inlet pipe and equipped with a first solenoid valve. The detection control assembly includes a controller, a processor, multiple pressure sensors, multiple electrical control boxes, and multiple alarms. The controller is electrically connected to the processor, each first solenoid valve, and each alarm. Each pressure sensor is electrically connected to its corresponding electrical control box and the processor. Each pressure sensor is used to detect the internal pressure within its corresponding test chamber. The multiple electrical control boxes are spaced apart on the support. This invention provides a multi-channel airtightness testing device that can not only perform airtightness testing on multiple test chambers but also achieve automated inflation, testing, and alarm functions, improving testing efficiency.

[0004] In the above-disclosed structure, multiple branch pipes are connected through the inflation assembly, which in turn connect to the housing for testing. However, the lack of a switching cylinder structure with a mounting cylinder connection makes it difficult to uniformly adjust the inflation. Furthermore, the absence of an internal sealing block prevents rotational adjustment to change the inflation position, hindering multi-channel switching testing and resulting in poor adaptability. Improvements are needed. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a multi-channel switching airtightness testing device. The device connects to the switching cylinder via an installation cylinder, and combines the internal sealing block with a tightening spring and connector. It can be assembled and positioned in combination, which facilitates unidirectional air intake after tightening, thus aiding in airtightness testing.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please refer to Figures 1, 4, and 5. A multi-channel switching airtightness testing device includes a mounting cylinder 1. A switching cylinder 11 is fixedly connected to the outer surface of the mounting cylinder 1. One end of the switching cylinder 11 has a connecting hole 12. A limit strip 13 is fixedly connected to the inner side of the switching cylinder 11. A sealing plate 14 is slidably installed at one end of the inner side of the switching cylinder 11. The outer circular surface of the sealing plate 14 has a notch 15, which can be combined with the limit strip 13 for guidance and support, preventing the sealing plate 14 from rotating and misaligning, ensuring sealing stability, and facilitating installation and use. The notch 15 is slidably connected to one end surface of the limit strip 13. A connector 16 is assembled and installed at the end of the switching cylinder 11. Both ends of the connector 16 have threaded heads 17. One end of the connector 16 has a through hole 18. One end of the connector 16 has a fixing groove 2. A tightening spring 21 is fixedly installed inside the fixing groove 2. One end of the tightening spring 21 is tightly connected to one side surface of the sealing plate 14. The internal rotating part of the housing 1 has a sealing block 22. One side of the sealing block 22 has an adjustment opening 23, which is located on the side of the connecting hole 12. In use, the testing chamber can be threaded on by the threaded head 17 and aligned with the connecting head 16 onto the switching cylinder 11. Then, it can be uniformly inflated from the mounting cylinder 1. By adjusting the opening 23 to different positions of the switching cylinder 11, the air pressure pushes the sealing plate 14 away from the connecting hole 12, and the gas can enter the switching cylinder 11 from the notch 15 and then enter the testing chamber through the through hole 18. After inflation, the top spring 21 can press the sealing plate 14 to reset and close, thus allowing air to enter in one direction and sealing and pressurizing the testing chamber for airtightness testing. By rotating the adjusting sealing block 22, the adjustment notch 23 can be aligned with different positions of the switching cylinder 11, allowing for multi-channel switching testing, which is efficient, stable, and highly adaptable.

[0027] Please refer to Figures 2 and 3. An air inlet pipe 24 is fixedly connected inside the sealing block 22. The air inlet pipe 24 is rotatably installed at one end of the mounting cylinder 1. One end outlet of the air inlet pipe 24 is located inside the adjustment opening 23. The air inlet pipe 24 is a right-angle pipe. A sealing ring 25 is fixedly connected to one end of the outer surface of the air inlet pipe 24. The sealing ring 25 is rotatably connected to the upper surface of the mounting cylinder 1. The air inlet pipe is installed through the sealing block. Combined with the sealing ring, it can be rotated and positioned, which is conducive to combined air intake and convenient to rotate and adjust the air intake direction. It is easy to control and use, and has high adaptability.

[0028] Please refer to Figures 1 and 2. A lever 27 is fixedly connected to one side of the air intake pipe 24. The lever 27 is located at the upper end of the mounting cylinder 1. A rotating joint 26 is rotatably installed on the upper surface of the air intake pipe 24. The rotating joint 26 is located at the upper end of the lever 27. The rotating joint 26 and the lever 27 are located at the upper end of the sealing ring 25. By installing the lever through the air intake pipe and combining it with the rotating joint at the end, an air source can be connected for inflation. It can also be manually rotated and adjusted, which is convenient, efficient, and easy to use. The rotating joint 26 is threaded onto the air source pipe, which allows for unified air intake. The air intake pipe 24 can be rotated by hand with the lever 27, and the sealing block 22 can be rotated and adjusted to change the orientation of the adjustment opening 23. It can be rotated and switched, which is convenient for adjustment and use, and provides efficient pressing.
