Description

Technical Field

[0001] The utility model relates to the technical field of desks, in particular to an adjustable lifting desk. Background Art

[0002] Desks are essential for daily life and office work. The height of traditional desks is fixed and cannot be adjusted according to the personal situation and actual needs of users, resulting in low comfort and various diseases such as spinal and lumbar problems after long-term use. An adjustable lifting desk can be adjusted according to the user's body size and height, improving comfort and relieving pain.

[0003] After retrieval, a Chinese patent with the publication number CN202322622291.5 discloses a conveniently assembled adjustable lifting desk. The center of the surface of the first gear is connected to a threaded lifting rod through a rotating shaft. A brake fixing block is installed on the threaded lifting rod, and a brake torsion spring is installed on the outer surface of the brake fixing block. One end of the brake torsion spring is fixedly engaged with a card slot at the lower end of the gearbox. By setting the brake fixing block in cooperation with the brake torsion spring, when the threaded lifting rod rotates clockwise, the gap between the brake torsion spring and the brake fixing block increases and loosens, reducing the friction force after loosening, thus facilitating the smoother lifting operation of the motor-driven screw rod. When the threaded lifting rod descends, the gap between the brake torsion spring and the brake fixing block decreases, increasing the friction force between the brake torsion spring and the plastic brake fixing block, achieving a good braking effect.

[0004] The above technical solution has the following defects. Although such a desk can lift the lifting desk according to the lead screw structure and position it through the brake block, in actual use, when positioning the desk through the brake block, the stability of the desk depends on the performance of the brake block. It is difficult to maintain stable use after the brake block ages. Therefore, an adjustable lifting desk is proposed. It is provided with a motor lifting component, so that the desktop can be lifted and adjusted as needed. The electric lifting components are arranged on both sides of the desktop and are controlled by the same stepper motor controller, so that the two electric lifting components can start and stop synchronously and drive the desktop to lift. A positioning frame is provided, so that after the electric lifting adjustment of the desktop is completed, the desktop can be positioned by four load-bearing rods, enabling the desktop to be stably used at the required height. The desktop is provided with a display lifting platform, which can be adjusted as needed, so that the computer display can be placed at an appropriate height for use.

[0005] In view of this, this creation improves and solves the above problems, conducts in-depth research and applies scientific principles, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background section is only intended to deepen the understanding of the overall background art of the present utility model, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art known to those skilled in the art.
