Columns 4 are disposed on both sides of the top of the first base plate 3. A water tank 5 is disposed in the middle of the first base plate 3. A second base plate 6 is movably disposed on the top of the columns 4. A first lifting drive cylinder 7 is disposed in the middle of the second base plate 6. A pressure rod assembly 8 is disposed at the output end of the first lifting drive cylinder 7. The pressure plate assembly 2 includes two connecting rods 9, a pressure plate 10, and a placement plate 11. The top two sides of the plate 10 are respectively connected to the bottom of the two connecting rods 9, and the top of the two connecting rods 9 are respectively connected to the bottom two sides of the second base plate 6. The two sides of the pressure plate 10 are respectively movably connected to the two connecting rods 9. The pressure plate 10 is located on the top of the placement plate 11. A floating component 12 is provided between the pressure plate 10 and the placement plate 11. The pressure rod component 8 is located on the top of the pressure plate 10. A second lifting drive cylinder 13 is provided on the column 4. The output end of the second lifting drive cylinder 13 is connected to the second base plate 6.

[0027] This invention employs a design combining a first lifting drive cylinder 7 and a second lifting drive cylinder 13 to precisely control the movement of the pressure rod assembly 8 and the second base plate 6. After the pressure rod assembly 8 presses down onto the pressure plate 10 to clamp the product on the placement table, the second lifting drive cylinder 13 drives the second base plate 6 to move downwards along the column 4, extending into the water tank 5 for testing. During the testing process, obvious air bubbles can be observed, allowing for a direct assessment of whether the parts are leaking. This ensures accurate pressure testing of hardware accessories, improves work efficiency, and is adaptable to parts of various specifications and shapes. The floating component 12 allows the pressure rod assembly 8 to move upwards by one stroke after releasing the pressure plate 10, facilitating the removal of the tested product.

[0028] This embodiment describes a hardware component leakage detection device. A fixing plate 14 is mounted on the top of the column 4, and the top of the fixing plate 14 is connected to the frame 1. Two second lifting drive cylinders 13 are provided, located on opposite sides of the bottom of the second base plate 6, with their output ends connected to the bottom sides of the second base plate 6. Specifically, the design of the fixing plate 14 and the two second lifting drive cylinders 13 enhances the stability of the second base plate 6, ensuring smoother vertical movement. The dual-cylinder drive not only improves the overall rigidity of the device but also reduces the potential off-center load problem caused by a single cylinder, thus improving the reliability and lifespan of the device.

[0029] It is understood that a linear bearing 15 can be provided on the second substrate 6, and the linear bearing 15 is slidably connected to the column 4 to improve stability.

[0030] This embodiment describes a hardware fitting leakage detection device. The pressure rod assembly 8 includes a connector 16, a pressure rod mounting plate 17, and multiple downward pressure rods 18. The connector 16 is located at the top of the pressure rod mounting plate 17, and the multiple downward pressure rods 18 are located at the bottom of the pressure rod mounting plate 17. The output end of the first lifting drive cylinder 7 is connected to the connector 16. Specifically, the design of the connector 16, pressure rod mounting plate 17, and multiple downward pressure rods 18 in the pressure rod assembly 8 enables uniform pressure to be applied to hardware fittings of different shapes and sizes. The design of multiple downward pressure rods 18 ensures the uniformity of pressure distribution, avoids detection errors caused by uneven local force, and improves the consistency and reliability of the detection results.

The floating pad 19 and the plug 21 are located at the upper and lower ends of the compression spring 20, respectively. Specifically, the presence of the compression spring 20 allows the pressure plate 10 to float freely within a certain range, ensuring close contact during the detection process while avoiding damage to the parts due to excessive pressure. Furthermore, after the detection is completed, when the pressure rod assembly 8 releases the pressure plate 10, the pressure plate 10 can move upwards by one stroke, facilitating the removal of the tested product.

[0032] In this embodiment, a hardware component leakage detection device is provided. The top of the second base plate 6 is equipped with two third lifting drive cylinders 24, and the output ends of the two third lifting drive cylinders 24 are respectively connected to two connecting rods 9. Specifically, the above-mentioned arrangement adjusts the position of the placement plate 11 for convenient loading and unloading of the tested products.

[0033] The hardware fittings leakage detection device described in this embodiment has a control panel 25 installed on the top of the frame 1. Specifically, in addition to basic control functions, the control panel 25 displays an inspection operation screen corresponding to several products to be inspected. If bubbles appear at a product location, the corresponding indicator on the operation screen can be pressed to indicate that the part at that location has a leakage problem, thus solving the problem of errors caused by relying on manual memory.
