Abstract
Description
Technical Field
[0001] This utility model relates to the field of magnetic axis keyboard technology, and in particular to a keyboard fixing device for testing the sensitivity of magnetic axis keyboard keys. Background Technology
[0002] The keyboard fixing device for magnetic axis keyboard key sensitivity testing is a specialized fixture used to fix the keyboard position during key sensitivity testing. Its core function is to firmly fix the magnetic axis keyboard under test onto the test platform using a stable mechanical structure (such as adjustable clamps, positioning pins, and anti-slip bases), ensuring that the keyboard does not shift, tilt, or wobble when pressed by test probes or automated equipment. This device provides a stable benchmark for the accurate measurement of sensitivity parameters such as key actuation force, actuation travel, and rebound speed, avoiding test data deviations caused by changes in keyboard position. It is a key auxiliary device for ensuring the accuracy and consistency of magnetic axis keyboard key performance testing.
[0003] Currently, the devices used to fix keyboards generally use a simple screw structure to push a clamping plate to position the keyboard shell and prevent displacement during testing. However, traditional clamping plates usually have smooth surfaces, and the clamping force can only be determined by feel. If the clamping force is too high, it can cause wear or cracks in the mold shell, resulting in damage to the keyboard shell. Utility Model Content

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0024] Example 1: Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a keyboard fixing device for testing the sensitivity of magnetic axis keyboard keys. It includes a keyboard body 2 on the top of the operating platform 1, extension plates 3 fixedly connected to the front and rear sides of the bottom of the operating platform 1, a clamping component 4 between the two extension plates 3, a first limiting plate 5 fixedly connected to the rear side of the top of the operating platform 1, and a reaction component 6 on one side of the first limiting plate 5.
[0025] The control panel 1 provides convenient support for the keyboard body 2, and the extension plate 3 facilitates the installation and fixation of the clamping component 4. The clamping component 4 can perform the clamping and fixing work on the keyboard body 2. The first limiting plate 5, in conjunction with the reaction component 6, facilitates the alarm work on the clamping strength.
[0026] The clamping assembly 4 includes a screw 401 and a second limiting plate 402. One end of the screw 401 is rotatably connected to one side of the extension plate 3 via a bearing, and the second limiting plate 402 is disposed on one side of the top of the operating table 1.
[0027] The screw 401 facilitates the subsequent driving of the second limiting plate 402 for clamping, thus ensuring that the keyboard body 2 will not wobble during testing.
[0028] Example 2: Reference Figures 3-4 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0029] Specifically, one side of the surface of the screw 401 is rotatably connected to the inside of the extension plate 3, one end of the screw 401 is fixedly connected to a torsion block 403, and the surface of the screw 401 is threadedly connected to an internal thread plate 404. The top of the internal thread plate 404 is fixedly connected to the second limiting plate 402.
[0030] When the user needs to fix and clamp the keyboard body 2, the user rotates the torsion block 403. As the torsion block 403 rotates, the screw 401 rotates. As the screw 401 rotates, the internal thread plate 404 moves. As the internal thread plate 404 moves, the second limiting plate 402 is driven to achieve the clamping work of the keyboard body 2.
[0031] Specifically, the operating table 1 has a limiting groove 405 inside for limiting the movement of the internal thread plate 404.
[0032] The limiting groove 405 facilitates the movement of the internal thread plate 404 and prevents the internal thread plate 404 from shifting during movement.
[0033] Specifically, both sides of the internal thread plate 404 are fixedly connected to a reinforcing plate 407, and one side of the reinforcing plate 407 is fixedly connected to the second limiting plate 402.
[0034] By fixing the reinforcing plate 407 between the internal thread plate 404 and the second limiting plate 402, the connection strength between the two can be improved, ensuring stability during long-term use.
[0035] Specifically, a first rubber strip 406 is fixedly connected to one side of the second limiting plate 402, and the first rubber strip 406 is arranged in an array.
[0036] The first rubber strip 406 is fixed to one side of the second limiting plate 402 in an array, which can buffer when it comes into contact with the keyboard body 2 and prevent hard contact from causing damage to the keyboard body 2.
[0037] Specifically, the reaction assembly 6 includes a pressure plate 601 and a lead screw 602. The pressure plate 601 is disposed on one side of the first limiting plate 5, and the lead screw 602 is threadedly connected to the inside of the pressure plate 601. One end of the lead screw 602 is fixedly connected to a torsion ring 603.
[0038] The pressure plate 601 facilitates the limiting installation of the lead screw 602, and the torsion ring 603 at one end of the lead screw 602 can adjust the left and right positions of the lead screw 602 inside the pressure plate 601.
[0039] Example 3: Reference Figures 3-4 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0040] Specifically, the reaction assembly 6 also includes a connecting frame 604 fixed to one side of the first limiting plate 5, and a pressure sensor 605 is fixedly connected to one side of the connecting frame 604.
[0041] The pressure sensor 605 is conveniently fixed by the connecting frame 604, and the pressure sensor 605 is used to work with the lead screw 602 to apply pressure to trigger an alarm.
[0042] Specifically, a limiting rod 606 is fixedly connected to one side of the pressure plate 601, and the surface of the limiting rod 606 is slidably connected to the inside of the first limiting plate 5.
[0043] The limiting rod 606 is fixed to one side of the pressure plate 601. When the pressure plate 601 moves, it will drive the limiting rod 606 to slide inside the first limiting plate 5, thereby limiting the movement path of the pressure plate 601 and preventing misalignment.
[0044] Specifically, the reaction assembly 6 also includes a buzzer 607 and a spring 608. The buzzer 607 is fixed on both sides of the top of the operating table 1 and is electrically connected to the pressure sensor 605. The spring 608 is fixed between the first limiting plate 5 and the pressure plate 601.
[0045] The pressure sensor 605 is electrically connected to the buzzer 607. When the lead screw 602 pushes the pressure plate 601 to gradually press against the pressure sensor 605, and the pressure reaches the preset threshold, the buzzer 607 will automatically sound an alarm to immediately remind the staff that the current clamping force is too tight and needs to be adjusted in time to prevent damage to the keyboard. At the same time, the two ends of the spring 608 are fixed between the first limit plate 5 and the pressure plate 601 respectively. Its elastic support can not only help limit the initial position of the pressure plate 601 to prevent it from shifting due to its own weight or external force, but also reduce the impact of rigid contact through the buffering effect during the adjustment of the lead screw 602, making the pressing action more stable and further improving the accuracy of clamping force control.
[0046] Specifically, a second rubber strip 7 is fixedly connected to one side of the first limiting plate 5, and the second rubber strip 7 is arranged in an array.
[0047] The second rubber strip 7, which is fixed in an array on one side of the first limiting plate 5, can serve to buffer and protect the side of the keyboard body 2 when it is clamped.
[0048] In use, first place the keyboard body 2 to be tested on the top of the operating table 1. Then, according to the clamping force required for different keyboards, rotate the torsion ring 603 to make the lead screw 602 rotate inside the pressure plate 601, adjusting the distance between the end of the lead screw 602 and the pressure sensor 605 to adjust the clamping force. Then, when the user needs to fix the keyboard body 2, rotate the torsion block 403. As the torsion block 403 rotates, it drives the screw 401 to rotate. As the screw 401 rotates, it causes the internal thread plate 404 to move. As the internal thread plate 404 moves, it drives the second limiting plate 402 to achieve the clamping work of the keyboard body 2. As the second limiting plate 402 moves... The keyboard body 2 will gradually come into contact with the first limiting plate 5. At this time, one side of the keyboard body 2 will first touch the pressing plate 601. As the pressing plate 601 moves, it will drive the lead screw 602 to move. When the pressing plate 601 moves, it will also drive the limiting rod 606 to move within the first limiting plate 5. Then, as the second limiting plate 402 gradually comes into contact with the first limiting plate 5, the first rubber strip 406 and the second rubber strip 7 will gradually be compressed and buffered. When the clamping reaches a certain degree, the lead screw 602 will press against the pressure sensor 605. When the pressure reaches the preset threshold, the buzzer 607 will automatically sound an alarm to remind the staff that the current clamping force is too tight and needs to be adjusted in time to prevent damage to the keyboard.
[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
