Lateral limiting device for lifting vertical column of operating table

Abstract

The invention discloses a lateral limiting device for a lifting vertical column of an operating table. The device comprises a cylindrical vertical column, wherein an outer cylinder which is matched with the vertical column is sleeved at the periphery of the vertical column; two symmetrical vertical right-angle grooves are milled on a cylinder of the vertical column; two longitudinal holes which are formed opposite to each other are drilled in the outer cylinder; a thread is formed at the outer end of each hole; a pin is arranged in each hole; a roller is arranged at the front end of each pin through a roller pin; each pin is connected with an adjusting screw which is arranged in the outer cylinder; the rear end of each pin extends out of the outer cylinder and is sleeved with a lock nut; and a spring washer is arranged between the lock nut and the outer cylinder. In the invention, front and rear positions of the two pins can be adjusted respectively, and the roller is arranged at the front end of each pin to ensure that the two rollers are effectively contacted with two sides of the right-angle grooves, so that the operating table can be adjusted up and down conveniently and is prevented from being rotated.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a lateral limiting device for a lifting column of an operating table. Background technique [0002] In the existing operating table, a pin is used for the lateral limit device, and the pin is installed on the outer cylinder, and a rectangular groove is milled in the column, and the front end of the pin is a rectangular structure, which matches the rectangular groove of the column, because The matching gap between the pin and the rectangular groove of the column cannot be adjusted. In mass production, some products inevitably have a large matching gap, which makes the lateral swing of the operating table too large. The operating table will rotate when it is adjusted up and down. convenient. Contents of the invention [0003] The object of the present invention is to overcome the above deficiencies and provide a lateral limiter for the lifting column of the operating...
