Cone pulley and spring balance device of medical X ray machine

Abstract

The invention discloses a cone pulley and spring balance device of a medical X ray machine, and belongs to the technical field of medical instruments. The cone pulley and spring balance device structurally consists of a lifting steel wire rope guide wheel (1), a spring fixing seat (2), a balance spring (3), a spring steel wire rope seat (4), a lifting steel wire rope (5), a spring steel wire rope (6), a cone pulley component (7), an X ray combined head (8), a stand column component (9) and a lifting guide rail (10), and is characterized in that the lifting steel wire rope (5) drives the cone pulley component (7) to rotate through the lifting steel wire rope guide wheel (1) when the X ray combined head (8) is pulled up and down, so that the spring steel wire rope (6) pulls the balance spring (3); the change of elastic force produced by extension and retraction of the balance spring (3) is converted into constant tension through the cone pulley component (7), so that the X ray combined head (8) is in a balance state at any position. The cone pulley and spring balance device has the advantages of light machine weight, compact structure, low manufacturing cost, safety, reliability and convenience in operation.

Description

technical field [0001] The invention belongs to the technical field of medical equipment. Background technique [0002] The existing X-ray machine lifting and balancing device usually adopts the following two methods: 1. Use a balance weight to balance the X-ray combined head. Due to the use of the balance weight, the weight of the entire equipment is increased, and the center of gravity is raised due to the use of the balance weight. Therefore, the stability of the equipment is poor; 2. Use a spring balancer to balance the X-ray combination head. Because the spring balancer is too large and has an irregular structural shape, and the volume and space of the medical X-ray machine are limited, it will bring problems to the structural design. Very difficult to even balance with a spring balancer. Contents of the invention [0003] The purpose of this design and invention is to overcome the defects caused by the above-mentioned balance device. It is an effective combination o...
