Abstract

The invention provides an electric lifting device applicable for industries such as cosmetology, medical treatment, and the like, and belongs to the technical field of electromechanical integration. The invention solves the problems that a lifting sleeve of the prior electric lifting chair has larger friction resistance and bigger noise in the lifting process. The electric lifting device comprises a body with a plug jack and a reducing motor, wherein the plug jack is provided with a screw mandrel and a push rod inside; the push rod is sleeved on the screw mandrel and in threaded connection with the screw mandrel; the inner end of the screw mandrel is connected with the reducing motor; the outer wall of the push rod and the inner wall of the plug jack form a first chamber; the inner wall of the push rod and the screw mandrel form a second chamber; lubricant oil is filled in the first chamber and the second chamber; and the push rod is provided with an oil communicating hole for communicating the first chamber and the second chamber, and a positioning mechanism for preventing the push rod rotating axially. The screw mandrel and the push rod of the electric lifting device are all soaked in the lubricant oil, and the electric lifting device adopts oil immersed lubrication so as to reduce wear of materials, reduce the noise and prolong the service life.

Description

technical field [0001] The invention belongs to the technical field of mechatronics, and relates to a lifting device, in particular to an electric lifting device suitable for industries such as beauty salons and medical treatment. Background technique [0002] In some work areas that often need to adjust the height of the platform, such as the beauty and hairdressing industry, it is necessary to adjust the height of the beauty chair or barber chair. The adjustment structure of the existing liftable seat mostly adopts a mechanical hydraulic lifting structure, and realizes the purpose of height adjustment through hydraulic jacking and unloading and lowering. [0003] In addition, in the field of medical dentistry, it is also necessary to adjust the relative height of the patient and the doctor to meet the needs of different operations, but these are all manually operated, which is not conducive to the aseptic operation of the operation and affects the normal operation of both ...
