[0002] As a peripheral electronic input device, the keyboard is composed of different key technologies and electronic switch systems. Its main function is to input data and can be used to operate other machines or devices in the computer system.
[0003] In order to adjust the height of the keyboard body to meet the different usage requirements of users, existing keyboards are generally equipped with an adjustment footrest hinged at the front end or rear end of the keyboard body. The height of the front end or rear end of the keyboard body can be adjusted by controlling the adjustment footrest to rotate relative to the keyboard body, so that the tilt angle of the keyboard body can be adjusted to meet the different usage requirements of users.
[0004] However, the existing keyboards are only provided with a rotating hinge mechanism between one end of the keyboard body and the adjustment tripod, and the rotating hinge mechanism can only enable the keyboard body and the adjustment tripod to rotate relative to each other to adjust the height of one end of the keyboard body. However, after the height of one end of the keyboard body is adjusted to the target height, the existing keyboards cannot ensure that the one end of the keyboard body and the adjustment tripod are stably maintained at this inclined placement angle. As a result, when the user is using the keyboard, the adjustment tripod is easily offset and rotated relative to the keyboard body under the action of the tapping force of the keys, resulting in the instability of the inclined placement angle of the keyboard body. The user then needs to frequently control the rotation of the adjustment tripod, which greatly affects the user experience. Summary of the invention

The present embodiment of the vertical swing multi-angle adjustable keyboard 10 only requires the user to control the relative rotation of the shell 11 and the supporting plate 13 once to adjust the keyboard body 101 and the supporting plate 13 to the target angle. The self-locking structure can self-lock the shell 11 and the supporting plate 13 to ensure that the keyboard body 101 and the supporting plate 13 are stably maintained at the target angle, thereby improving the user experience. In addition, the adjustment end of the supporting plate 13 of the vertical swing multi-angle adjustable keyboard 10 of the present embodiment is rotatably hinged to the rear end of the shell 11, and the supporting plate 13 is matched and extended with the bottom plate of the shell 11 in the keyboard width direction Y and the keyboard length direction X, respectively, so that the entire keyboard can be placed flat on the support table, such as Fig.17 , Fig.18 and Fig. 20 As shown, the keyboard as a whole can also be supported vertically on the support table, such as Fig.19 and Fig.21 As shown, the vertically adjustable multi-angle keyboard 10 of this embodiment can meet the different placement and usage requirements of users, thereby improving the user experience.
[0041] Combination Figure 7 , Figure 8 and Fig.11The self-locking structure of this embodiment also includes a silicone sleeve 128, and an embedded groove 1281 is formed on one end face of the silicone sleeve 128 in the length direction X of the keyboard. The metal sheet clamping ring 127 is located in the embedded groove 1281, and the ring sleeve portion 1282 of the silicone sleeve 128 is sleeved on the outer peripheral wall of the second rod end 1192 of the shaft rod 119 and is located in the retaining hole 161, and the open arms 1283 at both ends of the silicone sleeve 128 are located in the limiting hole 162, and an avoidance groove 1284 connected to the embedded groove 1281 is formed on the outer side surface of the open arm 1283 at one end, and the locking end of the locking member 17 passes through the avoidance groove 1284 and presses on the open arm 1272 at one end to force the hoop portion 1271 to hold the second rod end 1192 tightly. Due to the large elastic friction of the silicone sleeve 128, the metal sheet clamp 127 embedded in the silicone sleeve 128 can be firmly retained in the retaining hole 161 and the limiting hole 162 of the retaining seat 16, and the metal sheet clamp 127 embedded in the silicone sleeve 128 can be firmly retained on the outer peripheral wall of the second rod end 1192 of the shaft 119, so as to ensure the stability and reliability of the self-locking function. Specifically, the outer peripheral wall of the compression lock 17 of this embodiment is provided with an external thread, and the outer peripheral surface of the retaining seat 16 is provided with a threaded hole 163 connected to the limiting hole 162.
