Description

A four-column linkage lifting system for lifting tables

technical field

The utility model relates to the field of furniture, in particular to a four-column linkage lifting system for a lifting table.

Background technique

At present, there are lift tables on the market that can freely adjust the height, but most of the lift systems are single-column or two-column linkage. Such a lift system can also adapt to small desktops. The desktop is not very suitable, because the biggest disadvantage of such a lifting system is poor stability, and the stability cannot meet the demand.

Contents of the invention

In order to solve the above problems, the utility model proposes a four-column linkage lifting system for lifting tables with a simple structure, which has good stability and is firm and durable.

The utility model adopts the following technical solutions:

A four-column linkage lifting system for an elevating table, which includes four elevating table legs, a horizontally arranged transmission shaft and six reversing gear boxes, and two bevel gears that mesh vertically with each other are arranged in the reversing gear box The two ends of the transmission shaft are respectively connected to the first and second reversing gearboxes, the two ends of the first reversing gearbox are respectively connected to the third and fourth reversing gearboxes, and the two ends of the second reversing gearbox They are respectively connected with the fifth and sixth reversing gear boxes, and the third, fourth, fifth and sixth reversing gear boxes are respectively connected with four lifting table legs.

The rotation of the horizontal transmission shaft drives the first and second gear boxes to rotate in the horizontal direction, the first and second gear boxes drive the third, fourth, fifth, and sixth gear boxes to rotate in the vertical direction, and the third and second gear boxes rotate in the vertical direction. The fourth, fifth and sixth gear boxes drive the movable parts of the lifting table legs to move up and down, so that the height of the desktop can be adjusted freely.

Further, the transmission shaft is connected with a bidirectional output reduction motor. The bidirectional output gear motor is used as the driving force, which saves time and effort and has stable power.

Furthermore, the lifting movable parts of the four lifting table legs are lead screws. The screw drive is relatively stable, and the stroke adjustment is more convenient and easy to control.

Compared with the prior art, the utility model has the advantages and positive effects that: the lifting stability is good, it is suitable for larger or thicker desktops, and the operation saves time and effort.

Description of drawings

Fig. 1 is a structural schematic front view of the utility model;

Fig. 2 is a schematic top view of a partial structure of the utility model;

Among them, 1 is the transmission shaft, 2 is the bidirectional output reduction motor, 3 is the third gearbox, 4 is the first gearbox, 5 is the fourth gearbox, 6 is the sixth gearbox, 7 is the second gearbox, 8 is The 5th gear box, 9 are lift table legs.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1-2, the four-column linkage lifting system for lifting tables includes a bidirectional output reduction motor 2, a horizontally arranged transmission shaft 1, six reversing gear boxes and four lifting table legs 9, and six reversing gear boxes There are two bevel gears which mesh vertically with each other. The output shaft of the bidirectional output reduction motor 2 is connected to the transmission shaft 1 arranged horizontally. The two ends of the transmission shaft 1 are respectively connected to the first gearbox 4 and the second gearbox 7. The two ends of a gear box 4 are respectively connected with the third gear box 3 and the fourth gear box 5, the two ends of the second gear box 7 are respectively connected with the fifth gear box 8 and the sixth gear box 6, the third gear box 3, the Four gear boxes 5, the fifth gear box 8, and the sixth gear box 6 are connected with the movable parts of four lifting table legs 9 respectively, and the movable parts of four lifting table legs 9 are leading screws.

The two-way output deceleration motor drives the horizontal transmission shaft to rotate, and the horizontal transmission shaft rotates to drive the first and second gear boxes to rotate in the horizontal direction, and the first and second gear boxes drive the third, fourth, fifth, and sixth The gear box rotates in the vertical direction, and the third, fourth, fifth, and sixth gear boxes drive the lead screw of the lifting table leg to move up and down, so that the height of the desktop can be adjusted freely, with high stability and easy adjustment and control.

The above is only a preferred embodiment of the utility model, and it is not intended to limit the utility model in other forms. Any professional who is familiar with the technology can use the technology disclosed above to make changes and improvements. Content, any simple modification made to the above implementation according to the technical essence of the utility model still belongs to the protection scope of the technical solution of the utility model.
