Description

Cable telescopic bracket

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to cable telescopic bracket.

Background

Doctors usually need to do rehabilitation treatment on patients by means of medical instruments, and the patients generally require the rehabilitation instruments to have a posture adjusting function because the conditions of the patients are different, when the main structure of the instruments is telescopically adjusted, corresponding cables can be forcibly pulled or extruded if the cables cannot be similarly stretched, and after frequent repeated adjustment operation, the cables have high risk of being pressed off, worn and the like, so that electrical signal disorder of a machine is caused, normal operation of equipment and a system is influenced, and the function of a product is disabled.

For the above problems, the conventional method is to reserve sufficient space for the cable, so that the cable can be freely bent and stretched when the machine stretches, but the method has the advantages that the requirement on the wiring space is sharply increased along with the increase of the stretching stroke, the utilization rate of the internal space of the product is low at the moment, and the method obviously does not conform to the trend of miniaturization and compactness, so that the cable can move with the machine in space and reliability, and the ordered folding and unfolding are realized; patents CN206881896U and CN212151196U respectively propose a cable telescopic bracket, and a scissor type telescopic mechanism is used to drive a cable and a structure main body to synchronously extend and retract, so as to avoid over-stretching and extrusion; patent CN208018721U then proposes a scalable cable structure of ball mill equipment, and it twines the cable for the heliciform in advance to increase a guider and a plurality of sliding sleeves, sliding sleeve and cable circle one-to-one and fixed connection constitute the structure of spring wire, consequently realize the flexible of cable. The scheme can realize orderly extension and retraction of the cable to different degrees, but the condition of practical application is limited, and the cable cannot be applied particularly under the condition that the space is limited, and the cable can be freely bent in a conventional mode, so that on one hand, the required wiring space is large, the cable is not easy to hide, and on the other hand, the cable still has large risks of excessive bending, extrusion and friction due to disorder of the movement of the cable; the scissor type telescopic mechanisms proposed by patents CN206881896U and CN212151196U can determine the movement path of the cable, but they require a plurality of multi-stage connecting rods hinged to each other and the length of the connecting rods is limited by space, when the wiring space is small and the movement stroke is long, the number of the required connecting rods is greatly increased, too many movement connecting parts of the mechanism will cause cost increase, and the stability and reliability of the mechanism are reduced, which is not favorable for the long-term stable operation of the equipment; although the retractable cable structure proposed in patent CN208018721U can also achieve the extension and retraction of the cable, when the cable is thick and hard, the spiral winding, the sliding guide device and the cable connection device occupy a large space.
