[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0020] like Figure 1-Figure 3As shown, a rapid sealing detection plugging device provided by an embodiment of the utility model comprises a plugging base 1, an inserting block 3 is arranged at one end of the plugging base 1, a first gas injection channel 2 is jointly provided in the central area of ​​the plugging base 1 and the side of the inserting block 3, a conical slope is provided on the surface of the inserting block 3, and a sealing ring 4 is sleeved on the conical slope, an annular mounting groove 9 is provided on the conical slope of the inserting block 3, and the sealing ring 4 is installed inside the mounting groove 9, and the sealing ring 4 is made of elastic plastic material;

[0021] The outer side of the insertion block 3 is connected to a plug body 6, and a second gas injection channel 7 is opened in the central area of ​​one side of the plug body 6, and an embedding groove 5 is opened on the other side of the plug body 6, and a conical groove 10 is opened inside the embedding groove 5, and a reserved groove 8 is opened inside the conical groove 10, and the first gas injection channel 2, the embedding groove 5, the conical groove 10, the reserved groove 8 and the second gas injection channel 7 are all on the same axis.

[0022] The outer diameter of the insert block 3 is the same as the inner diameter of the engaging groove 5 , that is, the surface of the insert block 3 is closely attached to the inner wall of the engaging groove 5 , and the conical slope of the insert block 3 matches the conical groove 10 .

[0023] In one embodiment of the utility model, when the sealing detection plug device is used to perform a sealing test on the product to be tested, the plug base 1 is first fixedly set on an external testing workbench, and then the air inlet interface of the product to be tested is aligned with one end of the plug body 6, and then the product to be tested is pressed against the plug body 6 and the plug base 1 through the cylinder clamp. In this process, the end of the plug body 6 will be stuck in the air inlet interface of the product to be tested, and under the strong clamping force of the cylinder clamp, the plug body 6 and the product to be tested maintain a good sealing state;

[0024] With the support of the cylinder clamp, the insertion block 3 provided on the plug base 1 will be inserted into the inside of the embedded groove 5 provided on the plug body 6, and after the insertion block 3 of the plug base 1 is inserted into the inside of the embedded groove 5, the conical slope provided on the insertion block 3 will enter the inside of the conical groove 10, and as the conical slope goes deeper, the sealing ring 4 sleeved on the conical slope will tightly abut against the inner wall of the conical groove 10, so that a good sealing system is formed between the insertion block 3 and the plug body 6;

[0025] Then, the external gas source is injected into the interior of the first gas injection channel 2, and the gas is injected into the interior of the product to be tested through the reserved groove 8 of the first gas injection channel 2 and the second gas injection channel 7. During this process, the gas pressure sensor installed on the external gas source is continuously monitored to determine whether there is gas leakage inside the product to be tested.

[0026] Based on the above technical solution, when it is necessary to perform air tightness testing on different types of products, it is only necessary to unplug the plug body 6 from the plug base 1 to replace the plug body 6 of different specifications and sizes. There is no need to disassemble or replace the entire gas injection structure, thereby improving the convenience and work efficiency of air tightness testing.

[0027] The above technical solutions significantly improve the operating efficiency and product testing accuracy, while ensuring the durability and cost-effectiveness of the system. Its unique conical slope design and sealing ring 4 achieve excellent sealing and prevent gas leakage during testing. The quick change function simplifies the operation process, greatly reduces the changeover time, and enables the equipment to quickly adapt to the testing needs of different products. In addition, the universal and user-friendly design of the solution significantly improves the applicability of the equipment on multiple product lines, further strengthens product quality control, and ensures that each product meets strict quality standards.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
