Abstract

The invention relates to a lifting device, in particular to a lightweight seat lifting mechanism. The lightweight seat lifting mechanism comprises a hollow upright post and a movable inner pipe, wherein a seat plate support is fixed to the upper end of the hollow upright post; a handle is fixed below the seat plate support. The lightweight seat lifting mechanism is characterized in that a spring is fixed to the bottom of the hollow upright post; a lock rod is inserted into the center of the hollow upright post; a lock ring is arranged on the lock rod; the lock rod on the lower part of the lock ring is inserted into the center of the spring; a nylon tile sleeve is sleeved on the lock ring; the inner pipe is sleeved on the lock rod; the bottom end of the inner pipe is conical; the bottom end of the inner pipe is inserted into the center of the nylon tile sleeve. The lightweight seat lifting mechanism has the advantages of simple structure, labor conservation in adjustment, safety in use and convenience in installation.

Description

technical field [0001] The invention relates to a lifting device, in particular to a portable seat lifting mechanism. Background technique [0002] In daily life, people often need a portable lifting device to meet the needs of life and work. For example, small lifting devices installed on tables, chairs, bed cabinets, and drawing tables can be adjusted according to the height of a person, thereby bringing great convenience to people's life and work. There are many types of existing lifting devices. One type is to drive the piston rod to lift by hydraulic pressure or air pressure (such as a pneumatic chair lift). This type of device has the advantages of convenient adjustment and labor saving. However, due to poor sealing effect or If used for a long time, it is prone to pressure leakage, resulting in the shortcomings of automatically falling and not being able to lift after being raised during use; some pneumatic lift seats have also experienced explosion accidents. The o...
