Description

Technical Field

[0001] The utility model relates to a desk, in particular to a mobile lifting desk. Background Art

[0002] Traditional office white-collar workers sit in front of computer desks when working. Sitting for a long time can easily cause cervical and lumbar problems, resulting in sub-health. Out of the concept of health, standing office is gradually becoming popular, so standing desks are created. In the prior art, desks used for standing office are generally liftable and movable, including a desktop and a retractable support frame connected under the desktop. The retractable support frame includes an inner tube and an outer tube. The outer tube is provided with a lock hole. The common mechanism used for locking during the lifting process is set on the inner tube, which is composed of a switch similar to a seesaw and a reset spring. There is a lock plate on the switch that can be extended into the lock hole, and the restoring force of the spring is used to achieve locking and release. However, this locking mechanism is unstable. Due to the gravity of the desktop and the bracket, the outer tube of the bracket will tend to move downward, pressing the switch, which is easy to lose control and change the original height of the table. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of existing standing desks and provide a new type of mobile lifting desk. The utility model adds an anti-drop plate to overcome the problem of height loss caused by the gravity of the desktop and the bracket when the desktop does not need to be adjusted.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A movable lifting office desk comprises a desk panel and a bracket connected to the bottom of the panel, wherein the bracket is a liftable bracket and is composed of an inner tube and an outer tube, wherein a locking hole is arranged on the outer tube, and a locking mechanism is arranged on the inner tube, wherein the locking mechanism comprises a pin shaft, a locking block and a spring, wherein a circular hole adapted to the pin shaft is arranged on the locking block, and the pin shaft passes through the circular hole, and wherein the locking mechanism further comprises an anti-dropping sheet, wherein the anti-dropping sheet is a plastic sheet or a metal sheet, and is arranged between the spring and the locking hole, wherein one side of the anti-dropping sheet corresponding to the locking hole is narrowed to be an anti-dropping sheet end, wherein a protrusion is arranged on the locking block, and the size of the protrusion is adapted to the locking hole, and when the spring is reset, the protrusions on the anti-dropping sheet end and the locking block both extend into the locking hole, and when the spring is compressed, the protrusions on the anti-dropping sheet end and the locking block are both pushed out of the locking hole. In this way, after the anti-drop sheet is added and the height of the table top is adjusted, when the table is in use, the outer tube of the bracket is supported on the end of the anti-drop sheet, and the anti-drop sheet shares the weight of the bracket and the table top borne by the protrusion on the locking block, thereby achieving the purpose of preventing the table top from falling when the user moves the table. When the height of the table needs to be adjusted, the locking block is pressed, and the locking block pushes the anti-drop sheet and the spring to move inward, and the protrusion on the locking block and the end of the anti-drop sheet are both disengaged from the lock hole inward, releasing the lock, and the outer tube and the inner tube can move relative to each other. In addition, after the anti-drop sheet is set, a larger spring is no longer needed, and the smaller spring force can make it easier for the user to press the locking block, so that a smaller spring can be used to easily open and close and prevent the table top from falling.

[0006] Another preferred solution of the utility model is that the bracket includes two vertical telescopic rods and a horizontal U-shaped support foot, and the two vertical telescopic rods are respectively connected to the left and right sides of the horizontal U-shaped support foot. In this way, the horizontal U-shaped support foot increases the bottom support area, and the open end faces the user, which greatly reduces the impact on the foot when moving the table, and the person has little impact on the table when moving the foot.

[0007] Another preferred solution of the utility model is that the anti-drop sheet is a U-shaped sheet or an L-shaped sheet. When the U-shaped sheet is used, the outer bottom of the U-shaped sheet abuts against the spring and the inner bottom abuts against the locking block during adjustment. When the L-shaped sheet is used, one of the two sheets constituting the L-shaped sheet abuts against the spring and the other abuts against the locking block.

[0008] Another preferred solution of the utility model is that the panel is also provided with a groove for placing a tablet computer or a pen. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 2 The utility model is a partially enlarged structural schematic diagram of the locking mechanism of the movable lifting office desk. Figure 3 It is a perspective view of the locking mechanism of the utility model. Figure 4 This is an exploded view of the locking mechanism of the utility model. Figure 1-4 As shown, a movable lifting office desk includes a desk panel 1, a bracket 2 connected to the bottom of the panel, the bracket is a liftable bracket, composed of an inner tube 21 and an outer tube 22, a locking hole 23 is provided on the outer tube, and a locking mechanism 24 is provided on the inner tube, the locking mechanism includes a pin 25, a locking block 26 and a spring 27, a circular hole 28 adapted to the pin is provided on the locking block, and the pin passes through the circular hole, the locking mechanism also includes an anti-drop sheet 29, the anti-drop sheet is a plastic sheet or a metal sheet, the anti-drop sheet is arranged between the spring and the locking hole, and one side of the anti-drop sheet corresponding to the locking hole is narrowed to an anti-drop sheet end 30, the locking block has a protrusion 31, the size of the protrusion is adapted to the locking hole, when the spring is reset, the protrusion on the anti-drop sheet end and the locking block both extend into the locking hole, and when the spring is compressed, the protrusions on the anti-drop sheet end and the locking block are both pushed out of the locking hole. After adjusting the height of the tabletop, when the table is in use, the outer tube of the bracket is supported on the end of the anti-drop plate, and the anti-drop plate shares the weight of the bracket and the tabletop borne by the protrusion on the locking block, so that the tabletop does not drop when the user moves the table. When the height of the table needs to be adjusted, the locking block is pressed, and the locking block pushes the anti-drop plate and the spring to move inward, and the protrusion on the locking block and the end of the anti-drop plate are both inwardly disengaged from the lock hole, releasing the lock, and the outer tube and the inner tube can move relative to each other.

[0016] Another preferred embodiment of the utility model is that the bracket comprises two vertical telescopic rods 32, 33 and a horizontal U-shaped support leg 34, and the two vertical telescopic rods are respectively connected to the left and right sides of the horizontal U-shaped support leg. When in use, the open end can be directed toward the user, which greatly reduces the impact on the feet when moving the table, and the table will not be affected when the person moves his feet.

[0017] The anti-drop sheet is a U-shaped sheet, the cavity of which is adapted to the thickness of the locking block. The advantage of the U-shaped sheet is that the locking block can be placed in the cavity of the U-shaped sheet. When adjusting, the outer bottom of the U-shaped sheet presses against the spring, and the inner bottom presses against the locking block, which can limit the locking block during the pressing process. At the same time, the pressure of the bottom on the spring is more uniform, which prevents the locking block from shaking left and right during the pressing process. An L-shaped sheet can also be used. When adjusting, one of the two sheets constituting the L-shaped sheet presses against the spring, and the other presses against the locking block.

[0018] Furthermore, the panel is also provided with a groove 35. The groove is arranged in a transverse long strip shape for placing a tablet computer or a pen.
