Dual-pulley pathway mechanism for medical suspension bridge

Abstract

The invention discloses a dual-pulley pathway mechanism for a medical suspension bridge, and belongs to the field of medical equipment. The pathway mechanism comprises a guide rail and a sliding base which is arranged on the guide rail, wherein the cross section of the sliding base is of a U-shaped structure; two pulleys are respectively arranged on the inner and outer edges of two sides of the sliding base; chutes, which correspond to the pulleys, are respectively formed in two sides of the guide rail; and the pulleys are matched with the chutes and are capable of sliding along the chutes. The pulleys, which are arranged on the inner and outer edges of two sides of the sliding base, are operated in a mode of being matched with the chutes, and two sides of the sliding base are simultaneously exerted uniformly, so that the overall bearing capacity and balancing capacity of the sliding base are improved; therefore, the pathway mechanism can overcome the defect that the chute of the guide rail becomes deformed with the sliding of a single pulley, so as to improve the operating stability and reliability of the pathway mechanism.

Description

technical field [0001] The invention relates to a track mechanism, in particular to a double pulley track mechanism for a medical suspension bridge, belonging to the field of medical equipment. Background technique [0002] Medical suspension bridge is a common medical equipment, which can greatly facilitate patients and medical staff, and is now widely used in various medical places. During the use of medical suspension bridges, it is usually necessary to install track mechanisms to move various auxiliary loads. The overall bearing capacity of the existing track mechanisms is poor, and the guide rails are prone to deformation after long-term use, which will cause the pulleys to break away from the slide on the guide rails during the sliding process. The slot affects the use. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a double pulley track mechanism for medical susp...
