Lifting table and driving mechanism thereof

Abstract

The invention provides a lifting table and a driving mechanism thereof. For the driving mechanism, first pulleys are fixed to the lower ends of upper table leg bodies, and second pulleys and third pulleys are fixed to the upper ends of the upper table leg bodies; the lifting table further comprises first transmission belts and second transmission belts, one ends of the first transmission belts arefixed to the upper ends of lower table leg bodies, firstly bypass the first pulleys downwards and then bypass the second pulleys upwards, and the other ends of the first transmission belts bypass first driving wheels; one ends of the second transmission belts are also fixed to the lower table leg bodies, and bypass the third pulleys upwards, and the other ends of the second transmission belts wind second driving wheels; the first driving wheels and the second driving wheels are arranged on the same transmission shaft. The lifting table and the driving mechanism thereof have the advantages that the first transmission belts and the second transmission belts are arranged in the table legs of the left and right sides and driven by the driving wheels which rotate coaxially so that the table legs at the two sides can be stressed simultaneously and move up and down synchronously, and the occurrence of the situation that a table top inclines is avoided.

Description

technical field [0001] The invention relates to the field of lift tables, in particular to a lift table and a driving mechanism thereof. Background technique [0002] As a common piece of furniture, desks are often used to place office supplies such as computer monitors, files and books. In order to meet the needs of different groups of people and improve the user experience, the market has put forward higher requirements for the adjustability and automation of the table height. [0003] At present, most of the lift tables on the market use motors to control the balanced lifting mechanism, but when the force on the left and right sides of the desktop is uneven, such as when a heavy object is placed on one side, the lift table will appear that the left and right table legs will not rise and fall at the same time. In this case, the motor sometimes freezes and the tabletop tilts; in addition, devices such as screw rods installed inside the table legs are often used as a balanc...

AI Technical Summary

Problems solved by technology

However, this kind of lifting table uses a steel wire to connect a total of 8 pulleys on the left and right sides in series to form a circuit. The transmission path is particularly complicated and lengthy, and there are many stress points and turning points, so the transmission resistance is large.

In addition, because the left and right sides are connected in series, and the length of the steel wire is very long, the stress points do not bear force and move at the same time, but there is a sequence, so the force on the left and right sides will be unbalanced, movement out of sync
