Description

Technical Field

[0001] The utility model relates to a rapid airtightness detection tool and belongs to the technical field of airtightness testing devices. Background Art

[0002] In automobile air-conditioning pipelines, the joints on the pipelines can not only connect different pipeline components into a complete system to ensure the smooth flow of refrigerant or other fluids, but also adjust the connection angle and direction of the pipelines as needed to adapt to different installation environments and space layouts.

[0003] In order to ensure the normal operation and stable performance of the automobile air conditioning refrigeration system, it is essential to conduct air tightness testing on pipes with joints. However, due to the complex shapes of some joints, conventional air tightness testing tools may not be directly applied. In this case, sealing components such as sealing rings and C-type clamps are usually used to connect the pipe fittings to the air tightness testing equipment, but this method is not only cumbersome and time-consuming, but also the sealing strength is not ideal, and it is difficult to meet the high-precision and high-efficiency testing needs. Utility Model Content

[0004] The purpose of the utility model is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

[0005] The technical solution provided by the utility model is as follows: a rapid airtightness detection tool, comprising a tool body, a locking plate, a transfer nozzle and an air inlet nozzle, the tool body being provided with a transfer interface and an air inlet which are interconnected, the transfer interface being mounted with the transfer nozzle, the air inlet being mounted with the air inlet, a card slot being provided on the locking plate, the locking plate being movably mounted on the tool body, so that the card slot on the locking plate can be close to or away from the transfer nozzle.

[0006] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects: the adapter and the air inlet on the tool body of the utility model are interconnected to ensure the smooth flow of airflow, the adapter nozzle is installed on the adapter nozzle for connecting the joint of the pipe to be tested, and the air inlet nozzle is installed on the air inlet for providing the gas required for detection to the pipeline system; the card slot provided on the lock plate can make the lock plate avoid the pipeline of the pipe to be tested, so that the lock plate is pressed on the joint of the pipe to be tested, so that the joint of the pipe to be tested can fit tightly on the adapter nozzle to form a stable and reliable connection, effectively preventing the joint from falling off due to the increase of the pressure in the pipe during the air tightness test, thereby ensuring the smooth progress of the test process. The tool of the utility model can quickly connect and fix the pipe to be tested, simplify the air tightness test process of the pipeline, reduce cumbersome operation steps, and improve work efficiency.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, a sliding groove is provided on the tool body, a connecting column is slidably installed in the sliding groove, and the connecting column is connected to the locking plate.

[0009] The beneficial effect of adopting the above-mentioned further scheme is that the sliding groove cooperates with the connecting column so that the locking plate can move forward and backward along the sliding groove, thereby flexibly approaching or moving away from the adapter nozzle, providing a stable sliding action for the locking plate, and ensuring the smoothness and accuracy during operation: when air tightness testing is required, the operator only needs to push the locking plate forward so that the locking plate is clamped above the joint of the pipe to be tested, ensuring that the joint is tightly fitted with the adapter nozzle, effectively preventing gas leakage. After the test is completed, the locking plate can move backward and the tested pipe can be easily removed from the adapter nozzle, which not only simplifies the operation process and improves the detection efficiency, but also ensures the accuracy and reliability of the test results.

[0010] Furthermore, a baffle is provided at one end of the connecting column away from the locking plate, and the baffle is used to prevent the connecting column from slipping out of the sliding groove.

[0011] The beneficial effect of adopting the above further solution is that the baffle ensures the stability and safety of the tooling during use.

[0012] Furthermore, the adapter nozzle comprises an installation section and a docking section, the installation section is sealingly connected to the tool body, and the docking section is located outside the tool body and is used to connect to the joint of the pipe to be tested.

[0013] The beneficial effects of adopting the above further solution are as follows: first, the sealing connection between the installation section and the tool body effectively prevents gas leakage during the detection process, thereby ensuring the accuracy and reliability of the detection results. Secondly, the docking section is located outside the tool body and can be directly connected to the joint of the pipe to be detected, which reduces the difficulty of operation and improves work efficiency. In addition, the adapter nozzle can also be replaced or adjusted according to actual needs to adapt to pipes of different specifications and types to be detected.

[0014] Furthermore, a sealing groove is provided on the butt joint section, and the sealing groove is used for installing a sealing ring.

[0015] The beneficial effect of adopting the above further solution is that the sealing between the adapter nozzle and the joint of the pipe to be tested is enhanced, gas leakage is prevented, and the accuracy and reliability of the test result are ensured.

[0016] Furthermore, the adapter nozzle is made of nylon, polytetrafluoroethylene, polyetheretherketone or polycarbonate.

[0017] The beneficial effect of adopting the above further solution is that the adapter nozzles made of these materials can form a tighter fit with the joints of the pipe to be tested, effectively preventing gas leakage, thereby ensuring the accuracy of the test results.

The tool body 1 is provided with a transfer port and an air inlet that are interconnected. The transfer port is provided with the transfer nozzle 3, and the air inlet nozzle 4 is provided with a card slot 21. The card slot 21 is open on one side close to the transfer nozzle 3, so as to facilitate connection with the pipe 6 to be detected. The locking plate 2 is movably mounted on the tool body 1, so that the card slot 21 on the locking plate 2 can be close to or away from the transfer nozzle 3, thereby achieving the fixing and release of the pipe 6 to be detected.

[0030] The embodiment of the utility model does not limit the number of the adapter nozzle 3, the air inlet nozzle 4 and the card slot 21. In practical applications, the number of these components can be flexibly adjusted according to the specific structure and detection requirements of the pipe 6 to be detected. As long as the layout and number of the adapter nozzle 3, the air inlet nozzle 4 and the card slot 21 match the structure of the pipe 6 to be detected and can meet the detection requirements, the number of these components can be set according to actual needs.

[0031] More specifically, a sliding groove is provided on the tool body 1, and a connecting column 5 is slidably installed in the sliding groove. The connecting column 5 is connected to the locking plate 2, and the locking plate 2 can be driven to move closer to or away from the adapter nozzle 3 by pushing the connecting column 5 to slide in the sliding groove.

[0032] A baffle 51 is provided at one end of the connecting post 5 away from the locking plate 2 , and the baffle 51 can effectively limit the movement range of the connecting post 5 to ensure that it will not fall off or be damaged during operation.

[0033] The adapter nozzle 3 includes a mounting section 31 and a docking section 32 . The mounting section 31 is sealed and connected to the tool body 1 . The docking section 32 is located outside the tool body 1 and is used to connect to the joint 61 of the pipe 6 to be tested.

[0034] The butt joint section 32 is provided with a sealing groove 33 , in which a sealing ring is installed.

[0035] The embodiment of the utility model does not limit the material of the adapter nozzle 3. The adapter nozzle 3 can be made of nylon, polytetrafluoroethylene, polyetheretherketone or polycarbonate. As long as the connection requirements are met, they should be within the protection scope of the utility model.

[0036] like Figure 6 - Figure 8 As shown, the method of using the rapid airtightness detection tool of the utility model is as follows:

[0037] (1) Connect the joint 61 of the pipe to be tested 6 to the butt joint section 32 of the adapter nozzle 3, and install a sealing ring on the butt joint section 32 to enhance the sealing performance;

[0038] (2) Connect the air tightness tester to the air inlet nozzle 4 on the tooling body 1 to ensure that the air source connection is stable;

[0039] (3) Push the locking plate 2 forward, and the clamping groove 21 can avoid the pipeline of the pipe 6 to be tested, so that the locking plate 2 is tightly fitted above the joint 61 of the pipe 6 to be tested, and the clamping effect of the locking plate 2 ensures that the joint 61 is tightly connected to the adapter 3;

[0040] (4) The air tightness tester will perform inflation, pressure maintenance, testing and other steps according to the set parameters and record the test data;

[0041] (5) After the test is completed, turn off the power supply and air source connection of the air tightness tester, and finally pull the lock plate 2 backward to easily remove the tested pipe 6 from the adapter nozzle 3.

[0042] The rapid airtightness detection tooling of the utility model is easy to operate, can ensure that the sealing performance of the pipe 6 to be detected is accurately and reliably detected, and has high detection efficiency.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
