DETAILED DESCRIPTION

[0020] 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 of the embodiments.

[0021] Reference Figure 1-Figure 3 A retractable and foldable computer stand comprises a driving box 1, the front end of the driving box 1 is fixedly connected to two driving frames 2 correspondingly arranged on the left and right, the two driving frames 2 are both rotatably connected with threaded rods 3, the two threaded rods 3 are both threadedly sleeved with moving blocks 4, the rear ends of the two threaded rods 3 both penetrate the corresponding driving frames 2 and the driving box 1 and extend into the driving box 1, the two threaded rods 3 are rotatably connected to the driving box 1, the rear ends of the two threaded rods 3 are both fixedly connected with first bevel gears 5, a rotating shaft rod 6 is rotatably connected between the left and right inner walls of the driving box 1, two second bevel gears 7 correspondingly arranged on the left and right are fixedly sleeved on the rotating shaft rod 6, the two second bevel gears 7 are meshed with the corresponding first bevel gears 5, and a motor 8 for driving the rotating shaft rod 6 to rotate is fixedly installed on one side of the left and right outer sides of the driving box 1. When the motor 8 drives the rotating shaft 6 to rotate, the two second bevel gears 7 drive the meshed first bevel gear 5 to rotate. The two second bevel gears 7 are arranged relative to each other, so the rotation directions of the two second bevel gears 7 are opposite, and the thread rotation directions of the two threaded rods 3 are arranged oppositely. In this way, when the two second bevel gears 7 drive the two threaded rods 3 to rotate, the two threaded rods 3 turn in opposite directions and the thread rotation directions are opposite. The two moving blocks 4 threadedly sleeved on the two threaded rods 3 can move forward or backward at the same time. The two moving blocks 4 are in contact with the inner wall of the corresponding driving frame 2, which plays a limiting role on the moving blocks 4. The motor 8 has a remote control function, and the remote control device can be used to control the direction of its output end. The motor 8 with a remote control function is a prior art and will not be described in detail here.

[0022] The upper ends of the two driving frames 2 are fixedly connected to two first rectangular blocks 9 correspondingly arranged on the left and right, and the first support rods 10 are connected to the two first rectangular blocks 9 in a common rotation connection. The lower ends of the two first support rods 10 near the driving box 1 are fixedly connected to two second rectangular blocks 11 correspondingly arranged on the left and right, and the two second rectangular blocks 11 correspondingly arranged are connected to the connecting rods 12 in a common rotation connection. The upper ends of the two moving blocks 4 are fixedly connected to two third rectangular blocks 13 correspondingly arranged on the left and right, and the two third rectangular blocks 13 correspondingly arranged are connected to the corresponding connecting rods 12 in a common rotation connection away from the second rectangular blocks 11. When the moving block 4 moves forward, the lower end of the connecting rod 12 rotatably connected to the third rectangular block 13 is driven to move forward together, so that the connecting rod 12 is tilted and rotated downward, and the first support rod 10 supported by the rotational connection between the connecting rod 12 and the second rectangular block 11 is also tilted and rotated downward. Conversely, when the moving block 4 moves backward, the connecting rod 12 is tilted and rotated upward, supporting the first support rod 10 to rotate upward. When the moving block 4 moves forward to a certain extent, the second rectangular block 11 contacts the upper end of the driving frame 2 and is thus held, and the first support rod 10 tilts downward and rotates to the minimum angle, thereby achieving the folding of the entire bracket. When the first support rod 10 tilts downward and rotates to the minimum angle, it is not parallel to the driving frame 2, and a certain angle is reserved by the second rectangular block 11 to facilitate the subsequent backward movement of the moving block 4 to prop up the first support rod 10.

[0023] Two second support rods 14 are fixedly connected between the two first support rods 10 and arranged correspondingly in front and back. A plurality of heat dissipation holes 15 are provided on the two second support rods 14, and the front ends of the two second support rods 14 are hook-shaped. The user can place the laptop on the frame formed by connecting the two first support rods 10 and the two second support rods 14, and use the hook-shaped hooks at the front ends of the second support rods 14 to support the laptop. The plurality of heat dissipation holes 15 provided on the second support rods 14 can better dissipate the heat generated by the laptop during use.

[0024] When using the utility model, the user can place the laptop on the frame formed by connecting the two first support rods 10 and the two second support rods 14, and use the hook-shaped hook at the front end of the second support rod 14 to hold the laptop. When the angle of the stand needs to be adjusted, the remote control device can remotely control the direction of the motor 8 to make the two first support rods 10 tilt upward or downward, thereby adjusting the angle of the stand and the laptop placed thereon. When the stand is not in use, the remote control motor 8 can be used to make the two first support rods 10 tilt downward to the minimum angle, so as to achieve the effect of folding and storing the entire stand.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
