[0003] In the production of hardware components, pressure testing is a crucial step in assessing their quality and performance. Existing pressure testing fixtures suffer from structural design flaws: a single fixing method makes them unsuitable for hardware components of different sizes, leading to easy displacement during testing; the pressing device is labor-intensive to operate or lacks sufficient transmission precision, resulting in unstable pressure control; and the lack of an effective height limiting device leads to significant pressure variations within the same batch of tests, affecting the comparability and accuracy of test results. Furthermore, the pressure display on some fixtures is not intuitive, requiring additional measurements and reducing testing efficiency. Therefore, a new type of pressure testing fixture for hardware components is urgently needed. Utility Model Content

[0028] like Figures 1 to 5 As shown in the figure, this is an embodiment of the present invention, relating to a pressure testing fixture for a hardware component 11, including a fixture body 10. The fixture body 10 includes a pressing device 20, a pressure testing device 30, and a fixing module 40. The pressing device 20 is used to drive the pressure testing device 30 to press down. The pressing device 20 includes a support module 50, a lifting guide rod 21, and an operating handle 22. The support module 50 is connected to the lifting guide rod 21. The lifting guide rod 21 is connected to the operating handle 22. The operating handle 22 is used to drive the lifting guide rod 21 to move linearly. The pressure testing device 30 includes a pressure gauge 60 and an installation module 70. The pressure gauge 60 is fixedly mounted on one side of the installation module 70. The installation module 70 is connected to the lifting guide rod 21. The operating handle 22 drives the lifting guide rod 21 and causes the installation module 70 to move up and down. The fixing module 40 is movably connected to the support module 50 and is used to fix the hardware component 11.

[0029] Specifically, the support module 50, lifting guide rod 21, and operating handle 22 of the pressing device 20 work together to ensure stable and controllable pressing action; the pressure gauge 60 of the pressure testing device 30 cooperates with the installation module 70 to ensure accurate pressure detection; the fixing module 40 is movably connected to the support module 50 for easy installation of the hardware component 11. The overall structure is compact and reasonable, with clear division of labor among the modules and convenient operation, providing a basic framework for pressure testing of the hardware component 11 and ensuring the standardization and accuracy of the testing process.

[0030] Furthermore, the fixing module 40 includes two L-shaped supports 41, a fixing cross plate 42, and a locking screw 43. The two L-shaped supports 41 are arranged opposite to each other, and the fixing cross plate 42 is arranged across the top of the two L-shaped supports 41. The locking screw 43 is used to lock the hardware 11 to the fixing cross plate 42. Specifically, the two L-shaped supports are arranged opposite to each other to provide stable support, the fixing cross plate 42 forms a bearing surface across the top, and the locking screw 43 can be adjusted according to the size of the hardware 11. This not only securely locks the hardware 11 but also accommodates hardware 11 of different specifications, improving the versatility and fixing stability of the fixture and preventing the hardware 11 from shifting during testing and affecting the results.

[0031] Furthermore, the fixed horizontal plate 42 has a threaded hole 44, which is threadedly connected to the locking screw 43. Specifically, this design makes the installation and removal of the locking screw 43 more convenient, and the threaded connection provides a reliable tightening force, ensuring that the hardware 11 remains fixed during the test, thus guaranteeing the accuracy and repeatability of the pressure test.

[0032] Furthermore, the support module 50 includes a base 51, a support column 52, and a connecting box 53; the base 51 is connected to the bottom of the support column 52; the top of the support column 52 is connected to one side of the connecting box 53; the connecting box 53 is connected to the lifting guide rod 21 and the operating handle 22 respectively. Specifically, the base 51 provides a stable support foundation, the support column 52 determines the overall height, and the connecting box 53 integrates the lifting guide rod 21 and the operating handle 22 to form a stable mechanical transmission structure, ensuring uniform force transmission and reliable transmission during the pressing process, thereby improving the overall stability and durability of the fixture.

[0033] Furthermore, a positioning module 80 is provided above the base 51. The positioning module 80 is used to position the support module 50 supported on the base 51. The positioning module 80 includes two positioning plates 81 arranged perpendicularly to each other, and the inner side of the positioning plates 81 abuts against the L-shaped support 41. Specifically, the positioning module 80 can accurately position the fixing module 40, ensuring that the fixing module 40 is installed in the same position each time, thus guaranteeing the uniformity of test conditions. Especially in batch testing, it can effectively improve the consistency and comparability of test results.

[0034] Furthermore, the connecting box 53 is equipped with a rotating gear 54, which is connected to the operating handle 22 and meshes with the teeth 23 of the lifting guide rod 21. Specifically, through gear transmission, the rotational motion of the operating handle 22 is converted into the linear motion of the lifting guide rod 21. This transmission method not only saves effort in operation but also ensures the accuracy and stability of the motion, making the pressure gauge 60 pressing down smoothly and controllably, thus improving the testing accuracy.

[0035] Furthermore, the pressure gauge 60 includes a pressure sensing unit 61 and a display unit 62; the pressure sensing unit 61 is used to sense pressure, and the display unit 62 is used to display the pressure value. Specifically, the pressure sensing unit 61 senses the pressure borne by the hardware component 11 in real time, and the display unit 62 intuitively displays the pressure value, which facilitates operators to quickly read the data, reduces human error, and improves testing efficiency and data accuracy; in some embodiments, the pressure gauge 60 is a commonly used existing device.

[0036] Furthermore, the mounting module 70 includes an L-shaped mounting plate 71 and a mounting cross plate 72. The lower part of the L-shaped mounting plate 71 is connected to the lower part of the lifting guide rod 21, and the front part of the L-shaped mounting plate 71 is connected to the rear part of the pressure gauge 60. The mounting cross plate 72 is fixedly mounted on top of the L-shaped mounting plate 71 and connected to the upper part of the lifting guide rod 21. Specifically, the lower part of the L-shaped mounting plate is connected to the lifting guide rod 21, and the front part is connected to the pressure gauge 60. The mounting cross plate 72 is fixed on top and connected to the lifting guide rod 21, forming a stable connection structure to ensure that the pressure gauge 60 remains vertical and stable during lifting, making the pressure test data more reliable.

[0037] Furthermore, the fixture body 10 also includes height-limiting blocks 12 of varying heights. These height-limiting blocks 12 restrict the descent height of the pressure gauge 60 to ensure consistent downward pressure during testing of hardware parts 11 from the same batch. Specifically, by selecting height-limiting blocks 12 of different heights, the descent height of the pressure gauge 60 can be precisely limited, ensuring consistent downward stroke during testing of hardware parts 11 from the same batch, thereby guaranteeing consistent downward pressure, improving the consistency and reliability of test results, and meeting standardized testing requirements.

[0038] Furthermore, the height limiting block 12 is located behind the locking screw 43 and is detachably connected to the fixed horizontal plate 42. When the L-shaped mounting plate 71 descends, the height limiting block 12 abuts against the L-shaped mounting plate 71. Specifically, this arrangement makes the height limiting block 12 easy to install and can accurately limit the descent position of the L-shaped mounting plate 71 when it drives the pressure gauge 60, ensuring a consistent downward pressure for each test. The detachable design also facilitates the replacement of the height limiting block 12 according to different testing requirements.

[0039] The working principle of this utility model is as follows:

[0040] When the operating handle 22 is rotated, it drives the rotating gear 54 inside the connecting box 53 to rotate. The rotating gear 54 meshes with the teeth 23 of the lifting guide rod 21, converting the rotational motion into the linear motion of the lifting guide rod 21, which in turn drives the mounting module 70, including the L-shaped mounting plate 71 and the mounting cross plate 72, and the pressure gauge 60 to move up and down. The hardware component 11 is placed in the fixed module 40 and locked with the fixed cross plate 42 by the locking screw 4343 to ensure that the hardware component 11 is stable during testing. The pressure sensing part 61 of the pressure gauge 60 senses the pressure on the hardware component 11, and the display part 62 displays the pressure value in real time. The height limiting block 12 is detachably connected to the fixed cross plate 42. When the L-shaped mounting plate 71 descends, the height limiting block 12 abuts against it to limit the descent height and ensure that the downward pressure is consistent for hardware components 11 of the same batch during testing. The positioning module 80 above the base 51, which includes two vertical positioning plates 81, ensures that the fixing module 40 is installed in an accurate position. All components work together to achieve precise pressure testing of the hardware 11.

[0041] This utility model achieves stable fixing, precise pressing, and pressure detection of hardware component 11 through a multi-module collaborative design. The adjustable locking structure of the fixing module 40 adapts to hardware components 11 of different specifications, while the positioning module 80 ensures consistent installation. The pressing device 20 achieves labor-saving and precise lifting control through gear transmission. The pressure gauge 60 displays the pressure value intuitively, and the height limit block 12 ensures consistent pressing pressure within the same batch of tests. The overall structure is reasonable and easy to operate, effectively improving testing efficiency, accuracy, and reliability, and meeting the diverse and standardized needs of pressure testing of hardware component 11.

[0042] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
