Description

Technical Field

[0001] This utility model relates to the field of keyboard accessories technology, specifically a keyboard height adjustment bracket. Background Technology

[0002] With the diversification of work styles and people's increasing emphasis on a healthy office environment, the market demand for keyboard height-adjustable stands is constantly growing. On the one hand, people who work in offices for long periods of time face health problems in their cervical spine, shoulders, and wrists, and keyboard height-adjustable stands can effectively alleviate these problems by adjusting the height and angle of the keyboard.

[0003] A search revealed a utility model patent in China, CN216923926U, which discloses a highly flexible keyboard lifting bracket. The bracket includes an adjusting arm, a base, an extension plate, and a support plate. The base has evenly distributed threaded pre-drilled holes, and one end of the base has a first horizontal pivot. A first vertical pivot is located at the top of the first horizontal pivot. This utility model optimizes its performance by incorporating the support plate, base, and cable tray. During use, the cable tray at the bottom of the support plate facilitates this optimization.

[0004] The aforementioned device uses a tray to place the keyboard. Once the keyboard is placed on it, its position is unrestricted, so it is inevitable that it will move during use, especially when adjusting its tilt angle, which makes it inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to provide a keyboard height adjustment bracket to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a keyboard lifting bracket, comprising a mounting frame and a support base, wherein the mounting frame is located at the top of the support base, a receiving component is installed inside the mounting frame, and an adjusting component is installed outside the mounting frame, the receiving component comprising a receiving plate rotatably connected inside the mounting frame, the receiving plate being horizontally positioned, six limiting grooves being formed on the top outer wall of the receiving plate, three limiting grooves on one side being slidably inserted with the same clamping plate, a spring being fixedly connected to one side outer wall of the clamping plate, one end of the spring being fixedly connected to one side inner wall of the middle limiting groove, and the adjusting component comprising a rotating shaft of the receiving plate coaxially fixed at one end.

[0007] It can lift the keyboard while keeping its position stable, effectively preventing the keyboard from changing position randomly when used or its tilt adjusted, making it more convenient to use. One end of the keyboard is placed against the inner wall of one of the clamps, and pressure is applied to the clamps through the keyboard. The stress of the first spring is overcome and shortens, and the clamp will slide to one side along the limiting groove. Then, the other clamp is pushed to the other side. After the keyboard is placed, the restriction on the two clamps can be released. The first spring returns to its length and moves the clamp closer to the keyboard. At this time, the first spring is also in a compressed state, which makes the clamp press tightly against the outer wall of the keyboard, effectively preventing the keyboard from shifting.

[0008] As a further preferred embodiment of this technical solution, a hinge seat is fixedly connected to one side of the outer wall of the mounting frame, and a worm gear is rotatably connected inside the hinge seat. The worm gear meshes with a worm wheel. A vertically arranged limiting slide groove is provided on both sides of the top outer wall of the mounting frame, and the same horizontally arranged support cover is slidably inserted into the two limiting slide grooves.

[0009] As a further preferred embodiment of this technical solution, a horizontally arranged extension plate is fixedly connected to one end of the outer wall of the support cover, the receiving plate is in contact with the extension plate, and the bottom of the outer walls of both ends of the mounting frame is fixedly connected to the same horizontally arranged mounting plate. Multiple equidistantly distributed springs are fixedly connected between the mounting plate and the support cover, and the multiple springs are all arranged vertically.

[0010] The knob drives the worm gear to rotate inside the hinge. The worm gear rotates through meshing, which in turn causes the support plate to flip within the mounting bracket. This changes the tilt angle of the keyboard for easier use. As the support plate flips, it applies pressure to the support cover through the extension plate. The pressure applied to the support cover by the second spring is gradually overcome, and the support cover moves down along the slide groove at the top of the mounting bracket to adapt to the changes in the device. The reaction force of the compressed second spring is also applied to the support cover, ensuring that the user's wrist will not easily slip down when placed on it, thus improving the comfort of using the device.

[0011] As a further preferred embodiment of this technical solution, a lifting assembly is installed between the mounting frame and the support base. The lifting assembly includes a connecting block fixedly connected to the outer wall of one end of the mounting frame, and the connecting block is in contact with the inner wall of the mounting frame.

[0012] As a further preferred embodiment of this technical solution, a vertically arranged lead screw is rotatably connected inside the mounting bracket via a bearing, the connecting block is threaded onto the outside of the lead screw, and two vertically arranged limiting strips are fixedly connected inside the mounting bracket, with the connecting block slidably fitted inside the two limiting strips.

[0013] As a further preferred embodiment of this technical solution, each of the two limiting grooves in the middle is fixedly connected to a limiting rod, and the two clamping plates are respectively slidably sleeved on the outside of the two limiting rods.

[0014] As a further preferred embodiment of this technical solution, a through hole is provided at each of the four corners of the bottom inner wall of the mounting bracket.

[0015] This utility model provides a keyboard height-adjustable bracket, which has the following advantages:

[0016] (1) By setting up a support component, this utility model can lift the keyboard while keeping its position stable, effectively preventing the keyboard from changing position arbitrarily when used or when adjusting its tilt, making it more convenient to use. One end of the keyboard is placed against the inner wall of one of the clamps, and pressure is applied to the clamps by the keyboard. The stress of the first spring is overcome and shortened, and the clamp will slide along the limiting groove to one side. Then, the other clamp is pushed to the other side. After the keyboard is placed, the restriction on the two clamps can be released. The first spring returns to its length and moves the clamp closer to the keyboard. At this time, the first spring is also in a compressed state, so that the clamp is pressed tightly against the outer wall of the keyboard, effectively preventing the keyboard from shifting.

[0017] (2) This utility model sets up an adjustment component, and drives the worm gear to rotate inside the hinge seat by a knob. The worm gear drives the worm wheel to rotate through meshing. The worm wheel can drive the support plate to flip in the mounting frame, and the tilt angle of the keyboard will also change, making it easier to use. While the support plate is flipping, the support plate will apply pressure to the support cover through the extension plate. The pressure applied to the support cover by the second spring is gradually overcome, and the support cover will move down along the sliding groove opened at the top of the mounting frame, so that it can adapt to the changes of the device. The reaction force of the compressed second spring will also be applied to the support cover, thereby ensuring that the user's wrist will not easily move down when placed on it, which is conducive to improving the comfort of using the device.

[0023] 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.

[0024] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 3 As shown in this embodiment, a keyboard lifting bracket includes a mounting frame 1 and a support base 2. The mounting frame 1 is located at the top of the support base 2. A receiving component 4 is installed inside the mounting frame 1, and an adjusting component 6 is installed outside the mounting frame 1. The receiving component 4 includes a receiving plate 401 rotatably connected inside the mounting frame 1. The receiving plate 401 is horizontally arranged. Six limiting grooves 402 are opened on the top outer wall of the receiving plate 401. The same clamping plate 405 is slidably inserted into three limiting grooves 402 on one side. A rubber anti-slip pad is provided on the inner side of the clamping plate 405, so that the limiting effect of the clamping plate 405 is better. A spring 404 is fixedly connected to one side outer wall of the clamping plate 405. One end of the spring 404 is fixedly connected to the inner wall of one side of the middle limiting groove 402. The adjusting component 6 includes a worm gear 601 coaxially fixed to one end of the rotating shaft of the receiving plate 401.

[0025] One end of the keyboard is placed against the inner wall of one of the clamps 405. Pressure is then applied to the clamp 405 through the keyboard. The stress on the spring 404 is overcome and it shortens. The clamp 405 then slides to one side along the limiting groove 402. The other clamp 405 is then pushed to the other side. Once the keyboard is in place, the restriction on the two clamps 405 can be released. The spring 404 returns to its original length, causing the clamp 405 to move closer to the keyboard. At this time, the spring 404 is also in a compressed state, which allows the clamp 405 to press tightly against the outer wall of the keyboard, effectively preventing the keyboard from shifting.

[0026] like Figure 3 and Figure 4 As shown, a hinge seat 602 is fixedly connected to one side of the outer wall of the mounting frame 1. A worm gear 603 is rotatably connected inside the hinge seat 602. The worm gear 603 meshes with the worm wheel 601. A vertically set limiting slide groove is opened on both sides of the top outer wall of the mounting frame 1, and the same horizontally set support cover 604 is slidably inserted into the two limiting slide grooves.

[0027] A horizontally arranged extension plate 607 is fixedly connected to one end of the outer wall of the support cover 604. The receiving plate 401 is in contact with the extension plate 607. The bottom of the outer walls of both ends of the mounting bracket 1 is fixedly connected to the same horizontally arranged mounting plate 605. Multiple equally distributed springs 606 are fixedly connected between the mounting plate 605 and the support cover 604. All the multiple springs 606 are arranged vertically.

[0028] The worm gear 603 is driven to rotate inside the hinge 602 by a knob. The worm gear 603 drives the worm wheel 601 to rotate through meshing. The worm wheel 601 then drives the support plate 401 to flip in the mounting bracket 1, thereby changing the tilt angle of the keyboard for easier use. While the support plate 401 is flipping, it applies pressure to the support cover 604 through the extension plate 607. The pressure applied to the support cover 604 by the second spring 606 is gradually overcome, and the support cover 604 will move down along the sliding groove opened at the top of the mounting bracket 1 to adapt to the changes in the device. The reaction force of the compressed second spring 606 is also applied to the support cover 604, thereby ensuring that the user's wrist will not easily slip down when placed on it, which helps to improve the comfort of using the device.

[0029] like Figure 1 and Figure 2 As shown, the same lifting assembly 5 is installed between the mounting frame 1 and the support base 2. The lifting assembly 5 includes a connecting block 503 fixedly connected to the outer wall of one end of the mounting frame 1, and the connecting block 503 is in contact with the inner wall of the mounting frame 1.

[0030] The mounting bracket 1 is rotatably connected to a vertically arranged lead screw 501 via a bearing. The thread helix angle of the external thread is less than the equivalent friction angle, which ensures that it has a self-locking property. The connecting block 503 is threadedly sleeved on the outside of the lead screw 501. Two vertically arranged limit strips 502 are fixedly connected inside the mounting bracket 1. The connecting block 503 is slidably sleeved inside the two limit strips 502.

[0031] To adjust the keyboard height, rotate the screw 501 using the knob. The connecting block 503, driven by the screw 501 and in cooperation with the two limit bars 502, will move vertically. The mounting bracket 1 connected to the connecting block 503 will change, and the keyboard position will change accordingly.

[0032] like Figure 3 As shown, each of the two limiting grooves 402 in the middle is fixedly connected to a limiting rod 403. The two clamping plates 405 are slidably sleeved on the outside of the two limiting rods 403, which can limit the clamping plates 405 and thus prevent them from moving upward and losing their limiting effect.

[0033] like Figure 1 and Figure 2As shown, each of the four corners of the bottom inner wall of the mounting bracket 1 has a through hole 3, through which bolts can be connected to external equipment.

[0034] This utility model provides a keyboard height-adjustable bracket, the specific working principle of which is as follows:

[0035] When the device is in operation, first place the support in the required position. Alternatively, bolts can be passed through the through hole 3 to fix it to the external equipment, ensuring sufficient stability of the support. Then...

[0036] One end of the keyboard is placed against the inner wall of one of the clamping plates 405. Pressure is then applied to the clamping plate 405 via the keyboard. The stress on the spring 404 is overcome, causing it to shorten. The clamping plate 405 then slides to one side along the limiting groove 402. The other clamping plate 405 is then pushed to the other side. Once the keyboard is in place, the restriction on both clamping plates 405 can be released. The spring 404 returns to its original length, causing the clamping plate 405 to move closer to the keyboard. At this point, the spring 404 is also compressed, ensuring that the clamping plate 405 presses firmly against the outer wall of the keyboard, effectively preventing keyboard displacement.

[0037] The knob then drives the worm gear 603 to rotate inside the hinge 602. The worm gear 603, through engagement, drives the worm wheel 601 to rotate. The worm wheel 601 then rotates the support plate 401 within the mounting bracket 1, thus changing the keyboard's tilt angle for easier use. As the support plate 401 rotates, it applies pressure to the support cover 604 via the extension plate 607. The pressure exerted on the support cover 604 by the second spring 606 is gradually overcome, causing the support cover 604 to move downwards along the groove at the top of the mounting bracket 1, adapting to changes in the device's position. The reaction force of the compressed second spring 606 is also applied to the support cover 604, ensuring that the user's wrist does not easily slip downwards when placed on it, thus improving the comfort of using the device.

[0038] To adjust the keyboard height, rotate the screw 501 using the knob. The connecting block 503, driven by the screw 501 and in cooperation with the two limit bars 502, will move vertically. The mounting bracket 1 connected to the connecting block 503 will change, and the keyboard position will change accordingly.

[0039] 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.
