Description

Technical Field

[0001] This utility model relates to the field of keycap testing technology, specifically a keycap pull-out test hook module. Background Technology

[0002] A keyboard is a device for inputting instructions and data to operate computer equipment. It also refers to a set of function keys that are arranged by a system to operate a machine or device. During the keyboard manufacturing process, the keycaps need to be tested, and a hook module is needed during the testing process.

[0003] Chinese Patent No. CN202120105409.5 discloses a keycap pull-out test hook module that can effectively prevent breakage. It includes a mounting base, a hook assembly hinged to the mounting base at its upper end, and an elastic pressure plate disposed within the mounting base and pressing downward against the upper part of the hook assembly. Existing technology has a limited range of motion during use, and the hook assembly cannot maintain a parallel state with the key during clamping, making slippage likely. Utility Model Content

[0008] Preferably, a damping sleeve is welded to the middle position of the slider, and the damping sleeve is slidably mounted on the upper side of the slide rod.

[0009] Preferably, a wear-resistant layer is provided on the inner side of the inclined edge, and the wear-resistant layer is welded to the inner side of the four sides.

[0010] Preferably, the first spring has a guide rod inside, which is slidably connected to the housing, and the other end of the guide rod is welded to the outside of the moving block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. When the gripper and the button come into contact, the slider will move along the slide bar. The second spring will cushion the impact between the gripper and the button, preventing the gripper from breaking during use.

[0013] 2. The tungsten steel layer used in the wear-resistant layer has strong wear resistance, which can reduce the wear of the bevel during use and extend the service life of the bevel;

[0014] 3. The damping sleeve is designed to increase the friction between the slider and the slide rod, preventing vibration between them during use.

[0015] 4. The guide rod can restrict the movement direction of the moving block, so that the moving block can only move radially, thus avoiding the phenomenon of the moving block deviating during use. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 In this embodiment of the present invention, a keycap pull-out test hook module includes a housing 1: a miniature cylinder 5 is installed at the upper end of the housing 1, a square truncated block 6 is installed at the bottom end of the miniature cylinder 5, movable blocks 9 are installed around the square truncated block 6, a bevel 10 is provided on the inner side of the upper end of the movable block 9, a first spring 7 is installed between the movable block 9 and the housing, a sliding groove 2 is installed at the bottom end of the movable block 9, a sliding rod 12 is installed inside the sliding groove 2, a slider 14 is slidably installed at the upper end of the sliding rod 12, a second spring 13 is installed on the upper side of the sliding rod 12 at the outer side of the slider 14, and a gripper 3 is installed at the bottom end of the slider 14.

[0025] A rubber pad 4 is provided on the inner side of the gripper 3. The rubber pad 4 is attached to the inner side of the gripper 3 with adhesive. The rubber pad 4 can directly isolate the gripper 3 from direct contact with the material, avoiding wear on the workpiece during use. A corrosion-resistant layer 16 is provided on the outer side of the gripper 3. The corrosion-resistant layer 16 is a chrome-plated layer. The chrome-plated layer used in the corrosion-resistant layer 16 has strong corrosion resistance, which can reduce the corrosion of the gripper 3, reduce the corrosion suffered by the gripper 3 during use, and extend the service life of the gripper 3.

[0026] A damping sleeve 15 is welded to the middle of the slider 14. The damping sleeve 15 is slidably mounted on the upper side of the slide rod 12. The damping sleeve 15 is designed to increase the friction between the slider 14 and the slide rod 12, and to prevent the slider 14 and the slide rod 12 from shaking during use.

[0027] A wear-resistant layer 11 is provided on the inner side of the inclined edge 10. The wear-resistant layer 11 is welded to the inner side of the four sides. The tungsten steel layer used in the wear-resistant layer 11 has strong wear resistance, which can reduce the wear of the inclined edge 10 during use and extend the service life of the inclined edge 10.

[0028] The first spring 7 has a guide rod 8 inside, which is slidably connected to the housing 1. The other end of the guide rod 8 is welded to the outside of the moving block 9. The guide rod 8 can restrict the movement direction of the moving block 9, so that the moving block 9 can only move radially, thus avoiding the phenomenon of the moving block 9 deviating during use.

[0029] The working principle and usage process of this utility model are as follows: When clamping is required, the miniature cylinder 5 drives the square truncated block 6 to move downward. During the downward movement of the square truncated block 6, the slide groove 2 and the gripper 3 will open. After the gripper 3 opens, the miniature cylinder 5 drives the square truncated block 6 to retract, so that the gripper 3 grasps the button. When the gripper 3 grasps the button, in order to avoid excessive pressure at the moment of contact between the gripper 3 and the button, the slider 14 will move along the slide rod 12 when the gripper 3 and the button are in contact. The second spring 13 is used to buffer the impact between the gripper 3 and the button, so as to prevent the gripper 3 from breaking during use.

[0030] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
