A Dental Chair Lifting and Enlargement Mechanism

Abstract

The invention relates to a dental chair lifting and amplifying mechanism and belongs to the technical field of medical instrument manufacture. The dental chair lifting and amplifying mechanism is mainly characterized in that a support is vertically arranged on a fixed seat, a guide rail is fixed on the support, a fixed slide block and a movable slide block are arranged on the guide rail in a sliding mode, a chair connection frame and a mouth lamp connection frame are fixed on the fixed slide block, a spittoon connection frame is fixedly arranged on the movable slide block, chain wheels are arranged on the fixed slide block and the movable slide block, a motor is arranged on the fixed seat, a chain is arranged between the fixed seat, the chain wheel of the fixed slide block and the chain wheel of the movable slide block, an air spring is fixed on the movable slide block through one end of a pin shaft, and the other end of the air spring is fixed on the fixed seat. The dental chair lifting and amplifying mechanism is simple in structure, small in size, low in production cost, low in motor noise and generated resonance sound, stable in running, synchronous in linkage lifting, free of inclination and capable of overcoming load gravity to achieve the balance motion function.

Description

1. Technical field [0001] The invention relates to a medical dental chair device, in particular to a lifting and amplifying mechanism of a dental chair, which belongs to the technical field of medical equipment manufacturing. 2. Background technology [0002] At present, most of the known lifting mechanisms for dental chairs adopt a parallelogram structure, which requires a relatively large space. At the same time, it takes up the space under the patient's seat cushion when it is used. It is very inconvenient for doctors to use when seeing a doctor, and the three-fold seat cushion cannot be realized. The matching, and the need for a lot of casings at the same time increases the cost of the product and brings a lot of inconvenience to the user. [0003] The existing lifting mechanism of the dental chair is to design a hydraulic cylinder in the dental chair to push up and down or use an AC electrode. With this transmission mode, the running speed is relatively slow, the motor ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing medical dental chair lifting device has relatively slow running speed, complex structure, large volume, high production cost, and relatively large motor noise, so as to provide stable transmission during operation, relatively small resonance sound, and A dental chair lifting and magnifying mechanism that can ensure the synchronization of the linkage and lifting without tilting
