[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-5 , a keyboard axis body and keyboard, including a base 1, characterized in that a key axis body 2 is provided inside the base 1, and the key axis body 2 includes an upper shell 201, the bottom of the upper shell 201 is fitted with a lower shell 202, the top of the lower shell 202 is fixedly connected to a limit frame 4, a slider 5 is slidably connected to the inside of the limit frame 4, a limit slot 6 is provided on the side of the limit frame 4 close to the slider 5, and a limit block 7 is fixedly connected to the side of the slider 5 close to the limit frame 4, an adjusting slot 10 is provided inside the limit block 7, an adjusting plate 11 is slidably connected to the inner side wall of the adjusting slot 10, a spring 14 is fixedly connected to the side of the adjusting plate 11 close to the limit frame 4, a top plate 15 is fixedly connected to the side of the top plate 15 away from the spring 14, and an extrusion plate 16 is fixedly connected to the side of the top plate 15 away from the spring 14, 2 The internally installed limit frame 4 limits the slider 5 and makes the upper shell 201 and the lower shell 202 form the key shaft body 2. The spring 14 provided inside the limit block 7 squeezes the top plate 15 and the extrusion plate 16, so that the extrusion plate 16 fits with the limit block 7 provided inside the limit frame 4, thereby adjusting the pressing force and rebound speed of the slider 5, and thus can be adjusted according to different usage habits. The slider 5 is prone to collide with the limit device during rebound, resulting in noise. The upper and lower ends of the limit groove 6 provided on the side of the limit frame 4 close to the slider 5 are slightly wider than the middle part. The rebound of the slider 5 is adjusted by the extrusion plate 16, so that when the slider 5 drives the limit block 7 to rebound to the upper end of the limit frame 4, it can be buffered by the extrusion plate 16, thereby reducing the noise generated by the rebound of the slider 5.

[0024] Reference Figure 2 The bottom of the upper shell 201 is fixedly connected with a clamping block 203, and the outer wall of the lower shell 202 is provided with a clamping groove 204. The clamping block 203 drives the upper shell 201 to be clamped in the clamping groove 204 provided on the outer wall of the lower shell 202, so that the upper shell 201 and the lower shell 202 can be spliced ​​and clamped, so that the upper shell 201 and the lower shell 202 form the key shaft body 2, so that the key shaft body 2 can be quickly disassembled and decomposed, so that the slider 5 can be disassembled, and then the extrusion plate 16 inside the limit block 7 can be adjusted to make the key shaft body 2 suitable for the usage habits of different people.

[0025] Reference Figure 3The top of the slider 5 is fixedly connected with a mounting seat 21, and the top of the mounting seat 21 is sleeved with a keycap 3. By fixing the mounting seat 21 at the top center of the slider 5, the mounting seat 21 is used to install and fix the keycap 3, so that the keycap 3 can be sleeved on the top of the key shaft body 2, thereby driving the keycap 3 to rebound through the slider 5, and the keycap 3 drives the slider 5 to be pressed through the mounting seat 21.

[0026] Reference Figure 2-3 A sleeve column 8 is fixedly connected to the top center of the lower shell 202, and a return spring 9 is sleeved on the outer wall of the sleeve column 8. The lower end of the return spring 9 is limited by the sleeve column 8 installed on the top of the lower shell 202, and the upper end of the return spring 9 is located at the bottom center of the slider 5, so that the return spring 9 supports the slider 5, so that the slider 5 can rebound after being pressed by the compression of the return spring 9.

[0027] Reference Figure 5 The limit block 7 is provided with a positioning groove 12 through the adjustment groove 10, and a positioning block 13 is fixedly connected to the side of the adjustment plate 11 close to the positioning groove 12. The positioning groove 12 is provided at the center of the upper and lower sides of the adjustment groove 10, and the positioning blocks 13 installed at the upper and lower ends of the adjustment plate 11 are located inside the positioning groove 12, so that the positioning block 13 limits the adjustment plate 11 inside the positioning groove 12, so that the adjustment plate 11 can move along the positioning groove 12 under the limit of the positioning block 13.

[0028] Reference Figure 3 and Figure 5 A rotating groove 20 is provided on the side of the limit block 7 close to the limit frame 4, and a rotating shaft 17 is rotatably connected inside the rotating groove 20. The end of the rotating shaft 17 close to the limit block 7 is fixedly connected to the adjusting block 18, and the end of the rotating shaft 17 away from the adjusting block 18 is fixedly connected to the rotating plate 19. The rotating shaft 17 is driven by the rotating plate 19 to rotate the adjusting block 18. A rotating groove 20 is provided on the side of the limit block 7 close to the limit frame 4, so that the rotating shaft 17 is located inside the rotating groove 20 and rotates, thereby limiting the rotating shaft 17 and the adjusting block 18.

[0029] Reference Figure 5 The adjusting block 18 is elliptical, and the adjusting plate 11 is located on both sides of the adjusting block 18. By rotating the adjusting block 18, the adjusting block 18 squeezes the adjusting plates 11 on both sides, so that the adjusting plates 11 set on both sides squeeze the spring 14, and then the squeezing plate 16 fits with the limit frame 4, which can limit the slider 5 and the limit block 7. When the elliptical adjusting block 18 rotates, the long axis of the adjusting block 18 squeezes the adjusting plate 11.

[0030] A keyboard comprises the keyboard axis as described above.

[0031] Working principle: By sleeved the return spring 9 on the outer wall of the sleeve 8, the slider 5 is installed inside the limit frame 4, and the key shaft body 2 is composed of the upper shell 201 and the lower shell 202. Under the limit of the block 203 and the slot 204, the upper shell 201 and the lower shell 202 are fixed, and the slider 5 slides inside the limit slot 6 through the limit block 7. By rotating the rotating plate 19, the rotating shaft 17 drives the adjusting block 18 to rotate. The adjusting plate 11 can be squeezed by the adjusting block 18, thereby adjusting the squeezing force of the adjusting plate 11 on the spring 14, so that the spring 14 squeezes the top plate 15 and the extrusion plate 16, so that the extrusion plate 16 fits with the inner wall of the limit slot 6, and then the limit block 7 can be limited, thereby adjusting the friction force of the slider 5 inside the limit frame 4.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
