[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] Referring to the accompanying drawings: This height-adjustable computer stand includes a base 1 and a pillar 2 arranged on the base 1, a support arm 3 moving along the height direction of the pillar 2 is arranged on the pillar 2, a swingable connecting bracket 4 is hinged on the support arm 3, the interior of the pillar 2 is a hollow structure, and is provided with an adjusting screw 21 driven by a motor, the adjusting screw 21 is arranged along the height direction of the pillar 2, and is provided with a lifting seat 5 that is moved by rotating the adjusting screw 21, the lifting seat 5 is connected to the support arm 3, and a hand-cranked unit 6 that is moved by manually operating the lifting seat 5 is arranged at the lower end of the adjusting screw 21, a first moving block 7 that moves along the length direction of the support arm 3 and is hinged with the connecting bracket 4 is arranged in the support arm 3, and a hand-adjusting unit 8 that is moved by manually operating the first moving block 7 is arranged on the first moving block 7. The principle of the utility model is that the adjusting screw 21 is driven to rotate by manually operating the hand-crank unit 6, so that the adjusting screw 21 can continue to be adjustable when the motor fails to operate, thereby solving the problem that the lifting seat 5 cannot be adjusted further due to motor failure, and the hand-adjusting unit 8 directly replaces the motor-driven movement of the first moving block 7, that is, the swing of the connecting bracket 4 is achieved by the movement of the first moving block 7. The swinging structure of the connecting bracket 4 is disclosed in the comparative documents and will not be repeated here, so there is no situation where the motor fails. These two methods can delay the time when the computer stand needs maintenance.

[0022] The hand crank unit 6 includes a first bevel gear 61 and a second bevel gear 62 meshing with the first bevel gear 61. The first bevel gear 61 is arranged on the adjusting screw 21, and the second bevel gear 62 is rotatably arranged on the pillar 2 and the shaft portion extends outside the pillar 2. A hand crank handle 62-a is arranged on the shaft portion extending outside the pillar 2. The use of the bevel gear transmission method is not only simple in structure, but also convenient in setting. It can realize the rotation of the adjusting screw 21 by manual operation, and the bevel gear transmission has the advantages of good meshing performance, high overlap and relatively compact structure, which makes the transmission more stable.

[0023] A shaft sleeve 9 axially connected to the shaft rod portion of the second bevel gear 62 is provided on the pillar 2. The shaft sleeve 9 is not only used to increase the stability of the second bevel gear 62 set on the pillar 2, but also to increase the smoothness of the second bevel gear 62 during rotation, so that the adjusting screw 21 can be quickly driven to rotate, thereby improving the movement sensitivity of the lifting seat 5.

[0024] The manual adjustment unit 8 includes a rotating ring 81, a follower ring 82, and two connecting pieces 83. The rotating ring 81 is arranged on the support arm 3 by means of a threaded connection. The follower ring 82 is movably arranged on the support arm 3 and connected to the first moving block 7 by bolts. One end of the connecting piece 83 is arranged on the rotating ring 81, and the other end is placed in an annular channel 82-a in the follower ring 82 and moves along the track provided by the annular channel 82-a. When in use, the rotating ring 81 is threadedly connected so that it can move by rotating itself. The moving ring 82 moves along with the movement of the rotating ring 81, and in order to enable the following ring 82 to move along when the angle is adjusted and to move along when it is reset, a connecting piece 83 is provided. One end of the connecting piece 83 is provided on the rotating ring 81 and rotates along with the rotating ring 81, and the other end is placed in the annular channel 82-a of the following ring 82. The annular channel 82-a is set to accommodate the connection piece 83 to follow the rotation of the rotating ring 81, so as not to interfere with the rotation of the rotating ring 81, thereby realizing the following movement of the following ring 82.

[0026] The follower ring 82 includes a main body 82-b and a cover body 82-c. The annular channel 82-a is arranged in the main body 82-b and has a side opening 82-a1 for the connecting piece 83 to enter. The cover body 82-c covers the main body 82-b and partially blocks the side opening 82-a1. That is, after the connecting piece 83 is placed in the annular channel 83, the cover body 82-c is covered, and then the cover body 82-c is used to reduce the exposed area of ​​the side opening 82-a1 of the annular channel 82-a, so that the connecting piece 83 placed in the annular channel 82-a is confined in the annular channel 82-a, that is, it will not slip out of the annular channel 82-a, thereby realizing the follow-up of the follower ring 82.

[0027] The connecting member 83 includes a second movable block 83-a and a connecting rod 83-b. The second movable block 83-a is placed in the annular channel 82-a. One end of the connecting rod 83-b is eccentrically arranged on the second movable block 83-a, and the other end is arranged on the rotating ring 81. In order to adapt to the side opening 82-a1 of the annular channel 82-a being partially blocked by the cover body 82-c, the connecting member 83 is arranged to be an eccentric structure to adapt to the structure of the follower ring 82.

[0028] The base 1 is configured as a sheet-like component, which is bent to form an inserting portion 11, a connecting portion 12, and a supporting portion 13. The inserting portion 11 is inserted into the table body, and the connecting portion 12 is used to be connected to the pillar 2. A mobile phone holder 10 is provided on the supporting portion 13. The inserting portion 11 is inserted into the table body to ensure the installation of the base 1 and is then fastened by bolts. The connecting portion 12 is used to connect the base 1. The supporting portion 13 can not only be used to set the mobile phone holder 10, but also to place a keyboard to raise the use height of the keyboard.

[0029] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
