Description

Technical Field

[0001] The present application relates to the technical field of lifting tables, and in particular to a stepless height adjustment mechanism for lifting tables. Background Art

[0002] A lift table is a table that can adjust its height within a certain range, including lift-type desks. In order to adapt to the height requirements of different students and provide a healthier learning environment, many schools now use lift-type desks, allowing students to adjust the height of the desk according to their own height and comfort.

[0003] For example, the patent with publication number CN208354954U specifically discloses a liftable desk, including an outer rod, a mounting hole, an adjustment hole, a latch, a spring, and a setting bump. Through the elastic force of the spring, the latch automatically bounces back into the mounting hole in a natural state, thereby lifting and adjusting the desk. The adjustment method is simple and convenient, and has strong practicality.

[0004] When the liftable desk of the above patent is used, the height of the desk is adjusted by pulling out the pin and turning the rotary knob to offset the opening position of the protrusion and the mounting hole. After the height of the desk is adjusted, the protrusion is aligned with the opening position of the mounting hole, and the pin is inserted back into the mounting hole to fix the height of the desk. However, the height adjustment of the desk can only be achieved through the preset mounting holes, which makes it difficult to accurately adapt to the needs and comfort of the user. At the same time, when the desk is adjusted too high, the center of gravity will also rise, so that the desk is easily affected by external forces and shakes or falls. Therefore, it is necessary to design a stepless height adjustment mechanism for the lifting table to solve the above problems.

[0005] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

At the same time, when the desk is adjusted too high, the center of gravity will also increase, so that the table is easily affected by external forces and causes shaking or tipping.

[0007] The technical solution adopted by the present application to solve its technical problem is: a stepless height adjustment mechanism for a lifting table. Mainly including: a desk, the desk has two groups of hollow sleeve columns; two groups of support legs, the support legs are installed at one end of the sleeve columns, and the support legs have movable columns; a stepless adjustment component, the stepless adjustment component is installed on the desk, the stepless adjustment component includes: a first horizontal plate, the first horizontal plate is connected between the two groups of the hollow sleeve columns; a second horizontal plate, the second horizontal plate is connected between the two groups of the movable columns; a screw rod, the screw rod is threadedly connected to the second horizontal plate, one end of the screw rod is equipped with a fixed rod, and one end of the fixed rod is connected to the first horizontal plate; an auxiliary support component, the auxiliary support component is installed between the two groups of the support legs.

[0008] Furthermore, a gripping plate is installed at one end of the screw rod.

[0009] Furthermore, the auxiliary support assembly includes a base frame arranged between the two groups of support legs, and the base frame is equipped with two groups of support legs.

[0010] Furthermore, the base frame is a square frame structure, with sliding grooves at both ends of the inner wall of the base frame, and a cross rod is installed at the upper end of the base frame. The cross rod is two groups of mutually hinged oblique rods, one end of the oblique rod is installed with a sliding column, and the other ends of the two groups of oblique rods are movably installed with connecting rods.

[0011] Furthermore, springs are connected between the sliding columns of the two groups of oblique rods.

[0012] The beneficial effect of the present application is that the present application provides a stepless height adjustment mechanism for a lifting table, which realizes stepless height adjustment of the desk through the setting of a first horizontal plate, a second horizontal plate, a screw rod, a fixed rod, a base frame, legs, a slide groove, a cross rod, a slide column, a spring and a connecting rod, and can also provide auxiliary support for the desk after height adjustment to improve the stability of the desk placement.
