Abstract
The utility model relates to a rotating mechanism of a balance arm of a floor lamp, relating to the field of a medical apparatus and is arranged on the rotating balance arm of a medical floor lamp for a surgery. The rotating mechanism for the balance arm of the floor lamp is characterized by comprising a rotating connector A, a rotating connector B and a plurality of balls, wherein the boss of the rotating connector A is matched with the groove of the rotating connector B, the outer wall of the boss of the rotating connector A and the inner wall of the groove of the rotating connector B are respectively provided with a semicircular ball groove, the two semicircular ball grooves are combined to form a circular roller path when the rotating connector A and the rotating connector B are matched, and the balls are arranged in the circular roller path. Two components are connected through the balls in the grooves. With the balls, the two components can be pinned together, the sliding friction of the two components can be changed into roller friction to a certain extent, and the rotating resistance of the rotating arm can be reduced effectively.
Description
Technical field:
This utility model relates to medical instruments field, is specifically related to a kind of rotating mechanism of floor lamp counter-jib.
Background technology:
Vertical operating lamp at present commonly used and connect the formula operating lamp more and all include this seat and extension support arm or spin balancing arm, this seat all is to link together by swivel joint with extending support arm or spin balancing arm, and require not only to be connected firmly, it is flexibly movable also to want, and this utility model will provide a kind of rotating mechanism that can meet the demands.
The utility model content:
Technical problem to be solved in the utility model is to provide a kind of rotating mechanism of floor lamp counter-jib.
Technical problem to be solved in the utility model realizes by the following technical solutions:
