[0002] The product is a connector, as Figure 1 and Figure 2 shown, it is necessary to measure the leakage of the inner cavity of the product. Since the measurement part of the product is irregular in shape, an ordinary circular hose cannot be directly joined with the product. In addition, the product is formed by plastic injection molding, and there may be gaps at the connection between the plastic part and the metal part, i.e., the PIN foot, which affects the detection. The product will be assembled with corresponding seals later.

[0003] Based on the above defects and deficiencies, it is necessary to improve the existing technology and design an airtight test device for special-shaped products. Summary of the Utility Model

[0004] The main technical problem to be solved by the utility model is to provide an airtight test device for special-shaped products, which is ingeniously designed and can imitate the shape to seal the product port and the plug end, press the product, and measure the leakage of the product.

[0005] To solve the above technical problem, a technical solution adopted by the utility model is: to provide an airtight test device for special-shaped products, which includes a workbench, a positioning component arranged on the workbench for installing the product, a detection component docked with the product port on the positioning component, and a pressing and sealing component docked with the other end of the product. The positioning component is located between the detection component and the pressing and sealing component. The detection component includes a first linear slide rail, a left mold base, a first push clamp, a port seal, and a connector. The left mold base is slidably installed on the workbench through the first linear slide rail. A first push clamp for pushing the left mold base to slide along the first linear slide rail is installed on the workbench. A port seal is installed at one end of the left mold base facing the product port. The port seal is designed to imitate the product port. A connector is also installed on the left mold base. The connector communicates with the inner cavity of the product, and the connector is externally connected to a negative pressure detection device.

[0006] Preferably, the pressing and sealing component includes a second linear slide rail, a right mold base, a second push clamp, a plug seal, and a pressing member. The right mold base is slidably installed on the workbench through the second linear slide rail. A second push clamp for pushing the right mold base to slide along the second linear slide rail is installed on the workbench. A plug seal is installed at one end of the right mold base close to the product plug. Avoidance blind holes for avoiding the plug and the pins are provided on the plug seal and the right mold base. A pressing convex block extends horizontally outward at the lower end of the right mold base, and a pressing member is installed on the pressing convex block.

[0007] Preferably, the pressing member is made of an elastic material.

[0008] Preferably, the positioning assembly includes a positioning base and positioning pins. A sliding groove through-hole for placing the product is formed in the positioning base. Two positioning pins that cooperate with the positioning holes on the product are installed at one end of the positioning base close to the pressing and sealing assembly. An opening groove for avoiding the top bump of the product is also formed in the positioning base.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] The positioning assembly can quickly position the product to be detected for subsequent detection.

[0011] While pressing the product, the pressing and sealing assembly can conformally seal the plug end of the product to avoid the influence of voids caused by plastic shrinkage on the detection; an elastic member is used to press the product to avoid damaging the product.

[0012] The detection assembly uses a port seal that conformally inserts into the product port, enabling the negative pressure detection device to fit seamlessly with products of irregular shapes and enabling leakage measurement. Description of the Drawings
