Technical Field

[0001] This utility model relates to the field of condenser product testing technology, and in particular to a helium testing fixture for condenser airtightness testing. Background Technology

[0002] As a critical component in refrigeration systems and air conditioning equipment, the airtightness of the condenser directly affects the overall system's operating efficiency and safety. Even a minor leak can lead to refrigerant loss and increased energy consumption, potentially causing equipment malfunctions or even safety hazards. Therefore, high-precision airtightness testing of condensers is essential, and helium detection technology, with its high sensitivity and accuracy, has become an important method for condenser airtightness testing.

[0003] In the existing technology, the existing helium testing fixture for condenser air tightness testing has the following drawbacks: the fixture accuracy does not meet the requirements for compatibility with helium testing equipment, the fixture installation time is long, and a large number of other tools are required after the fixture is installed, which affects the efficiency of the operation.

[0006] Preferably, the bottom end of the hexagonal nut is fixed with a first threaded sleeve, and the top end of the pressure plate fixing block is provided with a threaded groove that matches the first threaded sleeve. Through the setting of the first threaded sleeve and the threaded groove, the hexagonal nut can be quickly installed and removed.

[0007] Preferably, a second threaded sleeve is fixed at the bottom end of the connecting pipe. The second threaded sleeve is threadedly connected to the inner wall of the hexagonal nut. By setting the second threaded sleeve, the connecting pipe can be installed inside the hexagonal nut.

[0008] Preferably, the bottom end of the connecting pipe is fixed with a first sealing sleeve on the inner wall of the second threaded sleeve. The first sealing sleeve is inserted into the pressure plate fixing block. By setting the first sealing sleeve, when the connecting pipe is installed in the hexagonal nut, the first sealing sleeve will be inserted into the pressure plate fixing block, so as to achieve the effect of sealing the gap between the hexagonal nut, the connecting pipe and the pressure plate fixing block.

[0009] Preferably, a third threaded sleeve is fixed to the top of the second connector, the third threaded sleeve is threadedly connected to the pressure plate fixing block, a second sealing sleeve is fixed to the top of the second connector, and a sealing groove matching the second sealing sleeve is opened at the bottom of the pressure plate fixing block. The third threaded sleeve facilitates the installation and removal of the second connector. When the second connector is installed, the second sealing sleeve is inserted into the sealing groove to seal the gap between the second connector and the pressure plate fixing block.

[0010] Preferably, the pressure plate fixing block has two mounting holes, two first friction-enhancing sleeves are fixed on the outer wall of the connecting pipe, and two second friction-enhancing sleeves are fixed on the outer wall of the second connector. By setting the first and second friction-enhancing sleeves, the friction force of the user rotating the connecting pipe and the second connector is increased.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, before operating the helium testing equipment for airtightness testing of condenser products, the hydraulic quick-connector of the airtightness testing helium testing fixture needs to be connected to the helium testing equipment connector in advance. Then, the condenser product is connected for airtightness testing via the second connector installed at the bottom of the pressure plate fixing block. The hydraulic quick-connector of this airtightness testing helium testing fixture, through the setting of the first sealing sleeve, has a sealing structure to ensure a tight connection with the helium testing equipment connector, effectively preventing gas leakage and improving the accuracy of the test. Simultaneously, the hydraulic quick-connector, through the setting of the second threaded sleeve, has a quick disassembly and assembly function, simplifying the connection steps and reducing installation time. The pressure plate fixing block is made of high-strength, high-precision materials, and the setting of the second connector ensures that the condenser product can be stably fixed during airtightness testing, preventing its movement or deformation, further improving the reliability and efficiency of the test. In addition, the design of the pressure plate fixing block also considers ease of operation and versatility, adapting to different specifications and models of condenser products, reducing the replacement cost and complexity of the fixture.
