In addition, the terms "first", "second", "third", "upper", "lower", "left", "right", etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance. At the same time, in the description of the present utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0022] The structure of the novel faucet sealing test device provided by this utility model is as follows: Figure 1 as well as Figure 3 As shown, the device includes a frame 1, a support frame 2 mounted on the surface of the frame 1, and a detachable bottom mold and sealing mechanism 7 connected to the bottom surface of the support frame 2. The bottom mold and sealing mechanism 7 are used for product placement and anti-clogging of the product outlet. The bottom mold and sealing mechanism 7 includes a test bottom mold 71 and a product plug 72. The test bottom mold 71 is fixed to the surface of the support frame 2 by bolts. The product plug 72 is used to seal the product outlet, and two O-rings 721 are also installed on the surface of the product plug 72 for sealing.

[0023] During implementation, after the product is placed into the test mold 71, two matching O-rings 721 are installed on the product plug 72. The double O-ring 721 sealing structure can further improve the sealing effect and effectively prevent gas leakage. The bottom of the product plug 72 is designed as a flat surface, which can be used for sealing and limiting, and can also ensure the accuracy of the plug installation depth.

[0024] Furthermore, such as Figure 2 as well as Figure 3 As shown, a pressing mechanism 5 is connected to the surface of the support frame 2. The pressing mechanism 5 is used for pressing down during anti-blocking operations. The pressing mechanism 5 includes a pressing cylinder 51 and a plug pressure plate 52. Two sets of pressing cylinders 51 are provided, and the two sets of pressing cylinders 51 are symmetrically fixed on the top of the support frame 2. The plug pressure plate 52 is slidably connected to the surface of the support frame 2, and the surface of the plug pressure plate 52 is fixedly connected to the output end of the pressing cylinder 51. The plug pressure plate 52 is used for pressing down the top support cylinder 82.

[0025] During implementation, after the product plug 72 is installed on the faucet outlet, the plug pressure plate 52 is fixed to the lower pressure cylinder 51 by a nut and passes through the four guide posts of the support frame 2. The plug pressure plate 52 is located above the product plug 72, which can prevent the product plug 72 from being pushed open during the inflation process, thereby avoiding misjudgment and unnecessary losses.

[0026] Furthermore, such as Figure 3 Figure and Figure 4 As shown, a quick-push mechanism 6 is installed on the top surface of the support frame 2. The quick-push mechanism 6 is used for connecting the product water inlet. The quick-push mechanism 6 is composed of a support plate 61, a quick-pull device 62, and an air inlet 63. The support plate 61 is fixed to the surface of the support frame 2, and the quick-pull device 62 is installed on the surface of the support plate 61. An air inlet 63 with an air inlet is installed at the bottom end of the quick-pull device 62. The air inlet of the air inlet 63 is connected to the leak detector 3 through an air pipe with a solenoid valve. An O-ring gasket 631 is fitted at the bottom end of the air inlet 63. The O-ring gasket 631 is used for sealing the product water inlet.

[0027] During implementation, the air inlet 63 is tightly connected to the water inlet of the faucet via a quick push-pull device 62. The O-ring 631 equipped at the air inlet 63 can effectively prevent gas leakage from the product cavity during inflation, thereby ensuring the accuracy of the test results.

[0028] Furthermore, such as Figure 2 as well as Figure 5As shown, a top support mechanism 8 is installed at the bottom of the support frame 2. The top support mechanism 8 is used to support the bottom of the product. The top support mechanism 8 includes a U-shaped support plate 81 and a top support cylinder 82. The U-shaped support plate 81 is fixed to the surface of the support frame 2, and the bottom of the U-shaped support plate 81 is equipped with a top support cylinder 82. The top support cylinder 82 is used to support the bottom of the product. Both the top support cylinder 82 and the pressing cylinder 51 are equipped with limit nuts.

[0029] During implementation, pressing the vent switch 43 will cause the solenoid valve to release the air pressure inside the product cavity, preparing for the operation of the top support cylinder 82. Then, pressing the top support cylinder switch 41 will cause the top support cylinder 82 to lift upwards. The top support cylinder 82 has a connector at the contact point with the faucet handle, which is used to fit the handle and press the product switch. The nut at the tail of the top support cylinder 82 can adjust the pressing stroke of the product switch to prevent damage to the product.

[0030] Furthermore, such as Figure 2 as well as Figure 3 As shown, a leak detector 3 and a control box 4 are respectively installed on the top of the equipment frame 1. The control box 4 is equipped with a top support cylinder switch 41, a bottom pressure cylinder switch 42, and a vent switch 43. The control box 4 is electrically connected to the bottom pressure cylinder 51 and the U-shaped support plate 81. The top support cylinder switch 41, the bottom pressure cylinder switch 42, and the vent switch 43 are all electrically connected to the control box 4. The top support cylinder switch 41 is used to control the top support cylinder 82, the bottom pressure cylinder switch 42 is used to control the synchronous operation of the two bottom pressure cylinders 51, and the vent switch 43 is used to control the pressure relief of the bottom pressure cylinder 51.

[0031] The main function of this utility model is product sealing performance testing, with the following features: First, high-efficiency testing: By using preset parameters, the sealing performance of the product before and after the valve is quickly tested, ensuring testing accuracy; Second, intelligent control: Utilizing a leak detector and cylinder system, the testing process is automated, improving testing efficiency; Third, double-sealing structure: The plug adopts a double O-ring sealing design, effectively preventing gas leakage and improving testing results; Fourth, flexible adaptation: The test mold and plug can be replaced for different products, adapting to various product testing needs; Fifth, safe testing: The cylinder limit nut and guide post are set to ensure accurate movement of the plug pressure plate, avoiding damage to the product.

[0032] Working principle: During operation, place the product inside the test mold 71, then activate the leak detector 3 and the cylinder button. The equipment will perform rigorous testing on the product before and after the valve according to preset parameters. If the leakage data of the product cavity within the specified time is lower than the standard value, it is judged as qualified (OK); otherwise, if the data exceeds the standard value, it is judged as unqualified (NG).

[0033] Specifically: On the leak detector 3, key parameters such as test time, inflation time, reading time and leakage value are first set. After the product is placed in the test mold 71, the air inlet 63 is tightly connected to the water inlet of the faucet by means of the quick push-pull device 62. The O-ring 631 equipped at the air inlet 63 can effectively prevent gas leakage from the product cavity during inflation, thereby ensuring the accuracy of the test results.

[0034] Meanwhile, two matching O-rings 721 are installed on the product plug 72. The double O-ring 721 sealing structure can further improve the sealing effect and effectively prevent gas leakage. The bottom of the product plug 72 is designed as a flat surface, which can be used for sealing and limiting, and also ensures the accuracy of the plug installation depth. After the product plug 72 is installed on the faucet outlet, the plug pressure plate 52 is fixed to the lower pressure cylinder 51 by a nut and passes through the four guide posts of the support frame 2. The plug pressure plate 52 is located above the product plug 72, which can prevent the product plug 72 from being pushed open during the inflation process, thereby avoiding misjudgment and unnecessary losses.

[0035] After the end cap pressure plate 52 passes through the guide post of the support frame 2, it not only provides orientation for the pressing cylinder 51 and the end cap pressure plate 52, but also effectively prevents misjudgment caused by the end cap pressure plate 52 being misaligned with the product end cap 72. After the pressing cylinder switch 42 is activated, the pressing cylinder 51 will drive the end cap pressure plate 52 to move up and down. The four guide posts of the support frame 2 ensure that the end cap pressure plate 52 moves vertically and avoids deviation. The limit nut at the upper end of the pressing cylinder 51 can ensure that the stroke range of the end cap pressure plate 52 is set under the premise of product safety, preventing leakage or damage to the product end cap 72 due to excessive or insufficient stroke.

[0036] After the downward cylinder 51 drives the plug pressure plate 52 to press down to the position, the leak detector 3 will start and perform a test on the product valve. If the leakage data of the product cavity within the specified time is lower than the standard value, it will be judged as qualified; otherwise, it will be judged as unqualified.

[0037] After the pre-valve test is passed, press the vent switch 43. The solenoid valve will release the air pressure inside the product cavity, preparing for the operation of the top support cylinder 82. Then press the top support cylinder switch 41. The top support cylinder 82 will be lifted upward. The top support cylinder 82 is designed with a connector at the contact point with the faucet handle to fit the handle and press the product switch. The nut at the tail of the top support cylinder 82 can adjust the pressing stroke of the product switch to prevent damage to the product.

[0038] After the support cylinder 82 moves upward and presses the faucet handle, the valve core will open. At this time, the leak detector 3 will be activated again to perform a post-valve test on the product. The product's inner cavity will be filled with air. The gas passes through the inner cavity and the valve core to reach the faucet outlet. The product plug 72 is installed at the outlet. The gas will push up the product plug 72. The plug pressure plate 52 set above can prevent the product plug 72 from being pushed out by the gas, which would cause leakage and misjudgment. If the leakage data of the product cavity within the specified time is lower than the standard value, it is judged as qualified; otherwise, it is judged as unqualified.

[0039] like Figure 5 As shown, when changing products, only the test mold 71 and the product plug 72 need to be replaced. After replacing the test mold 71, install the product plug 72 on the product and place it into the test mold 71. The double sealing O-ring 721 on the product plug 72 can prevent gas leakage when the product cavity is inflated. The test mold 71 can be provided with a corresponding plug groove to check whether the product plug 72 is properly assembled. If the product plug 72 cannot be installed into the plug groove, it proves that the product plug 72 is not properly assembled. The product plug 72 can also be installed into the plug groove. According to the length of the plug groove, a limiting post is provided at the rear end of the plug. The limiting post can prevent leakage and misjudgment caused by the product plug 72 moving backward when the product cavity is inflated. Finally, after pressing the air inlet 63 into the water inlet of the faucet through the quick push-pull device 62, the leak detector 3 can be started for testing.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
