The test unit 4 simulates the cyclic opening and closing state of the hook, and adjusts the opening and closing frequency and number of the hook body 2 according to the product positioning of the hook body 2, so as to accurately verify the durability under long-term high-frequency use. In conjunction with the setting of the load-bearing mobile unit 5, the hook body 2 can be placed horizontally to simulate the opening and closing of the hook, thereby meeting the test requirements under different installation states.

[0026] Furthermore, the test unit 4 includes: a rotating seat a6 fixed on the workbench 1, and a cylinder 8 is rotatably connected to the rotating seat a6 through a rotating seat b7, a turntable 10 is rotatably connected to the support plate 3 through a shaft 9, and a transmission plate 11 is fixed to the turntable 10, the output end of the cylinder 8 is rotatably connected to the transmission plate 11 through a rotating rod a12, and a connecting plate 14 is fixed to each of the two turntables 10, a pointer 50 is fixed to one of the rotating rods a12, and a scale 51 is fixed to the turntable 10. Through the arrangement of the pointer 50 and the scale 51, when the turntable 10 rotates along the axis of the rotating rod a12, the value of the pointer 50 on the scale 51 is used as an angle reference, which is convenient for the staff to observe the angle change.

The adjustment component 13 includes: a bracket 23 fixed on one of the support plates 3, and the bracket 23 and the support plate 3 are connected to a transmission shaft 24 for rotation.

An annular guide groove 49 is fixed on the support plate 3, and the toothed ring 32 is slidably connected in the annular guide groove 49. The addition of the annular guide groove 49 guides the toothed ring 32, ensuring that the movement of the toothed ring 32 is more stable when subjected to force. It should be noted that the configuration of the test unit 4 has the function of flexibly adjusting the opening and closing frequency and angle of the hook according to diverse demand scenarios, so that the opening and closing state of the hook in actual use can be accurately simulated, thereby significantly improving the accuracy and reliability of the test results of the hook opening and closing life. In addition, the opening and closing angle of the hook can be adjusted according to the specific needs of the actual application scenario, ensuring that the opening and closing state that is highly consistent with the actual use situation can be simulated more accurately, further optimizing the test effect. The test unit 4 is used to simulate the opening and closing principle of the hook: by installing the hook on the specified position of the workbench 1, the cylinder 8 is driven, and the hinged transmission effect of the rotating rod a12 is utilized to cause the turntable 10 to rotate along the axis of the shaft body 9, thereby driving the positioning component 15 on the connecting plate 14 to rotate synchronously, and then the hook can be driven to open and close; The principle of using the adjustment component 13 to adjust the rotation angle of the turntable 10 is as follows: the main shaft 25 is driven by the drive motor b26 to rotate synchronously, driving the worm 27 to rotate synchronously, and utilizing the meshing transmission effect between the worm 27 and the worm wheel 28 to drive the transmission shaft 24 to rotate synchronously, causing the spur gear b29 to rotate synchronously, and utilizing the meshing transmission effect between the spur gear b29 and the toothed ring 32 to drive the limit rod a33 to slide along the channel a30 and the channel b31 until the limit rod a33 is moved to the specified appropriate position, thereby completing the purpose of adjusting the angle limit of the turntable 10.

[0027] Example 2: Please refer to Figure 3-Figure 6 This embodiment further explains the first embodiment, and its difference lies in a method of testing the opening and closing of the hook body 2 in a horizontal installation state.

The limiting member 43 is used to adjust and limit the angle of the loading block 42. A suction cup 44 is fixed to the loading block 42. The limiting member 43 includes: a rod body 45 fixed to the mounting plate 35, and a mounting sleeve 36 on the loading block 42 is rotatably connected to the rod body 45. A limiting rod b46 is fixed to the rod body 45, and a limiting groove 47 is defined on the mounting sleeve 36. The limiting rod b46 is slidably connected in the limiting groove 47. It should be noted that, by providing the carrying and moving unit 5, the hook body 2 can be flexibly moved in a horizontal position, which greatly improves the convenience of operation. The user can easily use the suction cup 44 to accurately adsorb and position any designated position on the hook, thereby fully meeting the diverse needs of opening and closing tests at different positions, meeting the specific requirements of the hook opening and closing test in a horizontally installed state, ensuring the accuracy and reliability of the test, and greatly facilitating the detailed detection of the surface flatness of the hook body 2, providing strong technical support for the control of the quality of hook products. The carrying and moving unit 5 is used to test the opening and closing principle of the hook body 2 in a horizontal position: by installing the hook body 2 on the carrying frame 17, the driving motor a22 is used to drive the rotating shaft a20 to rotate synchronously, driving the spur gear a21 to rotate synchronously, and utilizing the meshing transmission effect between the spur gear a21 and the toothed plate 18 to drive the hook body 2 on the carrying frame 17 to move until the hook body 2 is moved to the appropriate position, and the hook is positioned by flipping the suction cup 44 and the suction cup 44 is used to simulate the flipping and opening and closing by the test unit 4.

[0029] Example 3: Please refer to Figure 1-Figure 2 and Figure 7-Figure 8 This embodiment further illustrates other embodiments, the difference being a method of positioning the hook body 2 .

[0030] Specifically, further, the connecting plate 14 is provided with a positioning assembly 15 adapted to the hook body 2, and the positioning assembly 15 is used to adsorb and position the hook body 2. The positioning assembly 15 includes: an additional plate 35 is rotatably connected to the connecting plate 14 through a rotating rod b34, a mounting sleeve 36 is fixed on the additional plate 35, a limiting rod 37 is slidably passed through the mounting sleeve 36, a mounting ring 38 is fixed on the limiting rod 37, and a spring 39 is sleeved on the limiting rod 37, one end of the spring 39 is fixed to the mounting ring 38, and the other end of the spring 39 is fixed to the mounting sleeve 36, a limiting disk 40 is fixed on the connecting plate 14, and at least two limiting holes 41 are provided on the limiting disk 40, and the limiting hole 41 is adapted to the limiting rod 37, a loading block 42 is provided on the additional plate 35, and a pull ring is fixed on the limiting rod 37.

When the additional plate 35 is adjusted to a vertical state with the connecting plate 14, the hook is adsorbed and positioned by the suction cup 44, so that the suction cup 44 can be tested for opening and closing flipping. When the additional plate 35 and the connecting plate 14 remain in a vertical state, it is convenient to perform a locking test on the hook body 2 in a horizontal installation state.
