Stable guiding telescopic mechanism for carrier

Abstract

The invention discloses a stable guiding telescopic mechanism for a carrier. The mechanism is arranged between the two ends of a carrier frame and the two ends of a hammock frame and comprises a first telescopic pipe, a second telescopic pipe and a third telescopic pipe. The first telescopic pipe, the second telescopic pipe and the third telescopic pipe are each of a hollow structure, a round through hole is formed in the bottom of the first telescopic pipe, the second telescopic pipe is inserted into the round through hole in the bottom of the first telescopic pipe, a round boss is arranged on the top of the second telescopic pipe, the third telescopic pipe is inserted into a round through hole in the bottom of the second telescopic pipe, a round boss is arranged on the top of the third telescopic pipe, and the lower portion of the third telescopic pipe is inserted into a through hole in the upper portion of a connecting sleeve; a separation blade is welded to the lower end of the third telescopic pipe, a round through hole is formed in the center of the separation blade, and an internal thread is arranged on the inner side of the connecting sleeve. The stable guiding telescopic mechanism has the advantages of being wide in application range and high in adaptability, secondary harm of shaking of a hammock to patients can be effectively avoided, and meanwhile the effect of protecting steel wire ropes is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a stable guiding telescopic mechanism for a transport vehicle. Background technique [0002] The existing trolley designed for critically ill patients consists of a frame and a hammock, and the hammock often needs to perform rising and falling movements. The existing trolley and the hammock are often directly connected by wire ropes. When the surgical trolley needs to be integrated When moving, the hammock will shake a lot, which will easily cause secondary injuries to the patient during the transfer; at the same time, the wire rope is repeatedly rising and falling, and the wire rope and the contact surface are rubbed against each other, which may easily cause the wire rope to break and fall sharply to the ground , seriously causing re-injury to the patient. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomi...
