Abstract

The utility model discloses an electric lift gynecological examining table, which comprises a bed frame, a bed plate, a base and a connecting arm for connecting the bed plate with the base. The bed plate is fixed on the bed frame. The connecting arm consists of an upper crank and a lower crank, which are the same in length. One ends of the upper and lower cranks are pivotably mounted in parallel at one side of the base, and the other ends are pivotably mounted with a triangular structure formed by a rocker, a connecting rod and the bed frame. The base is pivotably mounted with the upper or lower crank by an electric protraction/retraction means, so that the motion of a protraction/retraction shaft of the electric protraction/retraction means can drive the upper/lower cranks and the rocker to oscillate, thereby realizing the stable lifting/falling of said triangular structure and bed plate. The utility model has advantages of simple and compact structure, more space between the bed plate and base, and convenient operation, and is widely used for gynecological examination and gynecological operation.

Description

A kind of electric up-down obstetric examination bed

Technical field

This utility model relates to a kind of armarium, particularly a kind of electric up-down obstetric examination bed.

Background technology

The obstetric examination bed equipment that is absolutely necessary in department of obstetrics and gynecology are clinical, be generally and be convenient to the puerpera and in different stagess of labor, select different physiology positions to be beneficial to smooth production, people are more and more higher to the structure and the instructions for use of obstetric examination bed, so the lathe bed of obstetric examination bed adopts the liftable structure more, but the scalable linking arm that is used for connecting bed board and base in the at present common obstetric examination bed has four, so just make the overall structure of obstetric examination bed comparatively complicated, it is also bigger to take up room, and manipulates inconvenience.

Summary of the invention

In order to overcome the deficiencies in the prior art, this utility model provides a kind of linking arm simple and stable structure, occupies little space, easy to operate electric up-down obstetric examination bed.

The technical scheme that its technical problem that solves this utility model adopts is:
