[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1 to 4 As shown, in this embodiment, a button testing device includes a testing platform 1. Multiple support legs 2 are fixedly installed at the bottom of the testing platform 1. A fixed vertical plate 4 is suspended above the testing platform 1 and moves relative to the testing platform 1 via a lifting mechanism. A motor 5 is fixedly installed on one side wall of the fixed vertical plate 4. The output shaft of the motor 5 passes through the fixed vertical plate 4, and a disc 6 is fixedly connected to the end of the output shaft. A partially deflected external gear 7 is fixedly connected to the outer wall of the disc 6. A rack 8 is provided on one side of the disc 6, and the rack 8 is vertically arranged, meshing with the partially deflected external gear 7. A slider 9 is fixedly connected to the end of the rack 8 near the fixed vertical plate 4. 9 is slidably installed in a groove 10 opened on the side wall of the fixed vertical plate 4. A pressing rod 11 is fixedly connected to the end of the rack 8 away from the disc 6. The pressing rod 11 has an inverted L-shaped structure. A baffle 12 is sleeved on the upper side of the outer wall of the pressing rod 11. The baffle 12 is fixedly connected to the pressing rod 11. A sleeve 14 is sleeved on the lower side of the outer wall of the pressing rod 11. The sleeve 14 is slidably connected to the pressing rod 11. The sleeve 14 is fixedly connected to the side wall of the fixed vertical plate 4. A spring 13 is fixedly connected between the sleeve 14 and the baffle 12. The spring 13 is wound around the outer surface of the pressing rod 11. A limit plate 18 is provided on one side of the upper end of the baffle 12. The limit plate 18 is fixedly connected to the top of the fixed vertical plate 4.

[0021] The lifting mechanism consists of a fixed horizontal plate 3, guide rods 15, adjusting screws 16, and adjusting components 17. The fixed horizontal plate 3 is fixedly connected to the bottom of the fixed vertical plate 4. The bottoms of the two guide rods 15 are fixedly installed on the upper end of the testing table 1. The upper ends of the two guide rods 15 slide through the fixed horizontal plate 3 and the fixed vertical plate 4 in sequence. The bottom of the adjusting screw 16 is rotatably connected to the upper end of the testing table 1. The upper end of the adjusting screw 16 passes through the fixed horizontal plate 3. The adjusting screw 16 is threadedly engaged with the fixed horizontal plate 3. The upper end of the adjusting screw 16 is fixedly connected to the adjusting component 17.

[0022] In use, rotating the adjusting component 17 drives the adjusting screw 16 to rotate, thereby controlling the height of the fixed horizontal plate 3, and in turn controlling the height of the fixed vertical plate 4 and the pressing rod 11.

[0023] The outer wall of the adjusting component 17 is fixedly connected with multiple anti-slip seams, which are arranged in a ring array.

[0024] The anti-slip seams can increase the friction between the user's hand and the adjustment component 17.

[0025] The upper end of the testing platform 1 is also equipped with a clamping mechanism, which consists of two clamping components symmetrically distributed on both sides of the upper end of the testing platform 1.

[0026] The clamping assembly consists of a clamping plate 19, a mounting plate 20, movable blocks 21, an adjusting screw 23, and a handle 24. The mounting plate 20 is fixedly connected to the upper edge of the testing table 1. The clamping plate 19 is provided on the side of the mounting plate 20 near the middle of the testing table 1. Two movable blocks 21 are fixedly connected to the bottom of the clamping plate 19. The two movable blocks 21 are slidably installed in two movable slots 22 opened at the upper end of the testing table 1. The adjusting screw 23 is rotatably connected to the middle of the end of the clamping plate 19 near the mounting plate 20. The handle 24 is fixedly connected to the end of the adjusting screw 23.

[0027] In use, rotating the handle 24 causes the adjusting screw 23 to rotate, thereby moving the adjusting screw 23 along its axial direction and thus controlling the position of the clamping plate 19.

[0028] This utility model provides a button testing device, the specific working principle of which is as follows:

[0029] In use, place the device with the button to be tested on the testing table 1, positioning the button below the pressing rod 11. Then, turn the handle 24 to rotate the adjusting screw 23, causing it to move axially and control the position of the clamping plates 19. This clamps the two sides of the device, preventing it from becoming loose. Next, start the motor 5 to rotate the disc 6. The rotation of the disc 6 will rotate the external gear 7. When the external gear 7 contacts the rack 8, it will move the rack 8 downward, causing the pressing rod 11 to move downward and the baffle 12 to move downward, compressing the spring 13. The pressing rod 11 then moves downward... The downward movement will compress the button of the device under test. When the damaged external gear 7 separates from the rack 8, under the action of the spring 13 restoring its deformation, the pressing rod 11 and the rack 8 will move upward to return to their initial positions, thus completing one button press. The number of button presses is the same as the number of times the output shaft of motor 5 rotates. By controlling the number of times the output shaft of motor 5 rotates through the PID controller, the number of button presses can be controlled. The number of times the output shaft of motor 5 rotates is preset to N. After the button is pressed N times, if the button is still not damaged, it means that the button of the device sample is qualified. The value of N depends on the production requirements of the device under test.

[0030] For devices of different thicknesses to be tested (different thicknesses will result in different button heights), the adjusting component 17 can be rotated to drive the adjusting screw 16 to rotate, thereby controlling the height of the fixed horizontal plate 3, and in turn controlling the height of the fixed vertical plate 4 and the pressing rod 11, so as to ensure that the pressing rod 11 can be used for devices of different thicknesses to be tested.

[0031] It should be noted that the limiting plate 18 can limit the upper end of the baffle 12, thereby limiting the initial position of the rack 8 after it is restored, so as to ensure that the incomplete external gear 7 can mesh with the rack 8 when it rotates.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
