Description

Technical Field

[0001] The utility model belongs to the technical field of lifting tables, and in particular relates to a synchronous lifting table with a single lifting mechanism. Background Art

[0002] A lifting table is a table that can be raised or lowered. The height of the tabletop can be adjusted by lifting it to suit the user's height and different usage environments. Most existing lifting tables have a lifting mechanism on each side, and the tabletop is raised or lowered by adjusting the height of both sides simultaneously. This structure is not only costly, but also difficult to control both sides simultaneously, resulting in poor synchronization when the tabletop is raised or lowered, making it difficult to use. An existing mechanism for simultaneous bilateral lifting connects the legs on both sides by wrapping a wire rope around a pulley, allowing both sides to be raised or lowered simultaneously. However, the wire rope easily slips on the pulley, resulting in poor left-right synchronization and difficult to control the lifting speed. Utility Model Content

[0021] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a synchronous lifting table with a single lifting mechanism of the present invention in conjunction with the accompanying drawings.

[0022] like Figure 1-5 As shown, the utility model is a single-lifting mechanism synchronous lifting table, including a desktop panel 1, a table leg frame tube 3 and a base 8. A connecting beam 2 is provided under the desktop panel 1, and both ends of the connecting beam 2 are fixedly connected to the table leg frame tube 3. The table leg frame tube 3 includes an upper table leg frame 31 and a lower table leg frame 32. The upper table leg frame 31 and the lower table leg frame 32 are telescopically and slidably connected. The upper end of the upper table leg frame 31 is fixedly connected to the desktop panel 1, and the bottom of the lower table leg frame 32 is fixedly connected to the base 8. The table leg frame tube 3 is connected to the inside of the connecting beam 2 and is provided with a bilateral drive mechanism. The bilateral drive mechanism includes two synchronous belts 5, two gears 6 and two guide wheels 7. The gear 6 is rotatably set at the upper end of the table leg frame tube 3, and the guide wheel 7 is set inside the lower table leg frame 32. The two ends of the synchronous belt 5 are respectively fixed on the two lower table leg frames 32. The synchronous belt 5 is connected by the gear 6 and the guide wheel 7. When the lifting mechanism 4 on one side lifts the upper table leg frame 31 on one side, the upper table leg frame 31 on the other side will move upward at the same time under the action of the synchronous belt 5 and the gear 6, so that the entire table top 1 is raised and the table top height adjustment is realized.

[0023] Specifically, the two gears 6 are respectively installed at the joint of the upper table leg frame 31 and the table top panel 1. The front synchronous belt 5 passes around the guide wheel 7 on the right and then passes through the gear 6 on the right and the gear 6 on the left in turn, and then is connected to the lower table leg frame 32 on the left. The rear synchronous belt 5 passes around the guide wheel 6 on the left and then passes through the gear 6 on the left and the gear 6 on the right in turn, and then is connected to the lower table leg frame 32 on the right. The synchronous belt 5 is provided with teeth at the joint with the gear 6.

[0024] Lifting mechanism 4 is mounted within leg frame tube 3. Lifting mechanism 4 is preferably a pneumatic cylinder, with its lower portion mounted on the bottom of lower leg frame 32 and its upper portion mounted on the bottom of tabletop 1. Lifting mechanism 4 is connected to a lift adjustment switch 41 mounted in the middle of tabletop 1. To raise or lower the tabletop, the upward or downward movement of lift adjustment switch 41 is performed by pressing it upward or downward. Due to the length constraint of timing belt 5, when one upper leg frame 31 moves upward or downward, timing belt 5 pulls the other side's timing belt 5 upward or downward in sync. The coordinated teeth of timing belt 5 and gear 6 provide improved synchronization and smoother control.

[0025] In one embodiment, the base 8 is a leg frame 81, which connects the two lower leg frames 32. A leg frame base 82 is provided at the bottom of the leg frame 81. The upper portion of the lifting mechanism 4 is mounted in the middle of the tabletop 1, and the lower portion is mounted on the leg frame base 82. A leg cover 83 is provided at the bottom of the tabletop 1 outside the leg frame 81. This embodiment conceals the leg frame tubes and the lifting mechanism, resulting in a strong structural integrity and high stability.

Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention.
