Abstract

A medical multilevel synchronous telescopic cylinder belongs to the technical field of medical appliances, and structurally comprises a first layer column, a second layer column, a third layer column, a fourth layer column, fixed pulleys, wire ropes, fixing blocks, fixing plates, nuts, and the like, and the key point lies in that the first, the second, the third and the fourth layer columns are sequentially and mutually embedded to form a moving pair. A fixed pulley is mounted at the bottom of the second and the third layer columns respectively; one wire rope penetrates through one fixed pulley respectively; one end of the fixed rope is fixedly connected with the upper end fixing block of the lower layer column of the wire rope, while the other end of the wire rope passes around the fixed pulley to extend out of the fixing plate at the upper end of the upper layer column and fixed through the nut; generally, the first layer column serves as a frame, when the fourth layer column extends outward under external force traction, the second and the third layer columns extend outward for an equal degree; and when the fourth layer column retracts, the second and the third layer columns retract at the same time. The medical multilevel synchronous cylinder has the advantages of simple structure, stable running, convenience in operation, and big telescopic adjusting range.

Description

A kind of medical Synchronized Telescopic column casing

Technical field

The utility model belongs to technical field of medical instruments.

Background technique

Existing medical Synchronized Telescopic column casing, the general sprocket wheel chain drive mechanism that adopts realizes that Synchronized Telescopic moves, as patent ZL200880106961.3 (lifting rod that is used for the treatment of platform, hospital and Bed with special provision for nursing), complex structure, terminal can realize telescopic displacement amount little (being generally 0.2m-0.5m), narrow application range can not be applicable to the large medical equipment that needs the big telescopic displacement amount of 1.5m-2m.

Summary of the invention

Goal of the invention of the present utility model is: for overcoming the defective that prior art exists, design a kind of medical Synchronized Telescopic column casing, not only simple in structure, easy to operate, and the telescopic displacement amount is big, can be applicable to a tractor serves several purposes, the large medical equipment that often needs flexible adjustment position to use on a large scale.

The technological scheme that its technical problem that solves the utility model adopts is: its structure is made up of first layer post, second layer post, the 3rd layer of post, the 4th layer of post, static pulley, wire rope, fixed block, fixed plate, nut etc., structure outline is: it is polygonal thin-wall section that first layer post, second layer post, the 3rd layer of post, the 4th layer of post are gabarit, inner chamber has guiding groove except that the 4th layer of post, outer surface is equipped with bearing pack except that the first layer post, mutually nested successively composition sliding pair.The bottom of second layer post and the 3rd layer of post is equipped with a static pulley respectively, each static pulley is set with steel cable, one end of wire rope is fixed on its upper end fixed block of one deck post down, after the other end is walked around the upper end fixed plate that static pulley stretches out the last layer post, fix with nut, generally establishing the first layer post is frame, and the 4th layer of post is under external force traction when overhanging, and second layer post, also equivalent is overhanging simultaneously for the 3rd layer of post.Otherwise when the 4th layer of post indentation, then second layer post, the 3rd layer of post are withdrawn simultaneously.

The beneficial effects of the utility model are: simple in structure, operate steadily, and easy to operate, the telescopic adjustment scope is big.
