[0022] 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.

[0023] In practical implementation: such as Figure 1-5 As shown, a height-adjustable keyboard includes:

[0024] The keyboard body 1 and the frame 101 are provided, with the keyboard body 1 located inside the frame 101.

[0025] Adjustment structure 2 is set on frame 101 and is used to adjust the height of keyboard body 1;

[0026] The adjustment structure 2 includes two sets of symmetrical adjustment slots 201 on the bottom of the keyboard body 1. The cross-sectional shape of the adjustment slots 201 is a right trapezoid, and there are two adjustment slots 201 in each set. The four adjustment slots 201 are distributed in a rectangular shape.

[0027] The keyboard body 1 has a slider that is fixedly connected to the inner wall of the frame 101. The keyboard body 1 is installed on the inner side of the frame 101, and most of its main body is located on the outside of the frame 101. When adjusting the height, the position of its base part is mainly adjusted, so it will not affect the normal use of the keyboard body 1.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, two symmetrically distributed slide plates 204 are slidably connected to the inner side of the frame 101, and two symmetrically distributed top blocks 205 are fixedly connected to the top of the slide plates 204. The upper end of the top block 205 is slidably connected to the inner wall of the adjacent adjustment groove 201.

[0029] The inner wall of the frame 101 is rotatably connected to a two-way lead screw 203, and both slide plates 204 are threadedly connected to the surface of the two-way lead screw 203. The cross-sectional shape of the slide plate 204 is "T".

[0030] One end of the bidirectional lead screw 203 passes through the frame 101 and is fixedly connected to a wheel 206. The surface of the wheel 206 is provided with anti-slip texture. A stop block 207 is fixedly connected to the surface of the frame 101. The wheel 206 is located inside the stop block 207, and a notch is opened at the top of the stop block 207.

[0031] The bidirectional lead screw 203 is a relatively mature component in existing technology applications. It has two threaded grooves with opposite helical directions, and two slide plates 204 are threadedly connected to the two threaded grooves respectively. The cross-sectional shape of the slide plate 204 is "T" shaped, so that the two slide plates 204 will move closer to each other during the rotation of the bidirectional lead screw 203 without causing them to rotate synchronously. In this case, a guide rod can also be used to guide the rotation process by passing through the slide plate 204. The setting of the guide rod is a common technical means in existing technology applications, and will not be elaborated on here.

[0032] Rotating the wheel 206 can drive the bidirectional lead screw 203 to rotate. During this process, the two slides 204 can move closer to each other along the inner wall of the frame 101, thereby causing the top block 205 to slide along the inner wall of the adjustment groove 201. During this process, the inclined surface of the inner wall of the adjustment groove 201 can be used to gradually push the keyboard body 1 to move upward along the inner wall of the frame 101, thereby achieving the effect of adjusting the height of the keyboard body 1.

[0033] The notch design facilitates the operation of the rotary wheel 206, and the anti-slip texture on the surface of the rotary wheel 206 facilitates its operation by the user.

[0034] like Figure 1 and Figure 5 As shown, the frame 101 has two symmetrically distributed sliding grooves 209 inside, and the inner wall of the sliding grooves 209 has uniformly distributed limiting grooves 210.

[0035] Adjustment blocks 208 are provided on both sides of the frame 101. Pressing cavities are opened on the surface of the adjustment blocks 208. Pressing blocks 211 are slidably connected to the inner wall of the pressing cavities. Connecting rods 213 are fixedly connected to the surface of the pressing blocks 211. The other end of the connecting rods 213 passes through the adjustment blocks 208 and the frame 101 in sequence and is fixedly connected to a limiting block 212 located inside the limiting groove 210.

[0036] A spring 202 is fixedly connected to the surface of the pressing block 211, and the other end of the spring 202 is fixedly connected to the inner wall of the pressing cavity.

[0037] Specifically, the diameter of the limiting block 212 is smaller than the diameter of the connecting rod 213;

[0038] By squeezing the pressing block 211, it slides along the inner wall of the pressing cavity. At the same time, squeezing the spring 202 can drive the connecting rod 213 to separate the limiting block 212 from the limiting groove 210. This can then drive the adjusting block 208 to move down. After moving down to the appropriate position, releasing the pressing block 211 will cause it to reset under the action of the spring 202, allowing it to insert into the adjacent limiting groove 210. This achieves the effect of limiting the position of the adjusting block 208, enabling the adjustment of the tilt angle of the keyboard body 1, increasing the adjustment range, and making it suitable for different users.

[0039] In use, rotating the wheel 206 drives the bidirectional lead screw 203 to rotate. During this process, the two sliding plates 204 move closer to each other along the inner wall of the frame 101, thereby causing the top block 205 to slide along the inner wall of the adjustment groove 201. During this process, the inclined surface of the inner wall of the adjustment groove 201 gradually pushes the keyboard body 1 upward along the inner wall of the frame 101, thereby achieving the effect of adjusting the height of the keyboard body 1. By squeezing the pressing block 211, it slides along the inner wall of the pressing cavity. At the same time, squeezing the spring 202 drives the connecting rod 213 to separate the limiting block 212 from the limiting groove 210, thereby causing the adjusting block 208 to move downward. After moving to the appropriate position, releasing the pressing block 211 will cause it to reset under the action of the spring 202, allowing it to insert into the adjacent limiting groove 210 to achieve the effect of limiting the position of the adjusting block 208. This enables the adjustment of the tilt angle of the keyboard body 1, improves the adjustment range, and makes it suitable for different users.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
