Concealed cable coil spring take-up pre-tightening structure for medical X-ray machine

Abstract

The invention discloses a concealed cable coil spring take-up pre-tightening structure for a medical X-ray machine. The invention belongs to the technical field of medical instruments, and is characterized in that a total central shaft is composed of a circlip for a hole, a bearing space ring, a deep groove ball bearing, a steel wire retainer ring for a shaft, an inner hexagon screw M4x8, a central shaft, a tapered roller bearing, a central bearing seat inner hexagon screw M3x8, a cross recessed countersunk head screw M6x20, a central shaft seat and the like; a coil spring mounting box composed of a spring base, a worm gear, a spring cover plate and a take-up spring can be mounted on a main center shaft, and the coil spring mounting box can rotate freely and relatively on a transmission mechanism composed of a bevel gear, a gear base, a gear shaft sleeve, a deep groove ball bearing and a worm bearing seat. It can be ensured and predicted that the condition of self-release of force does not generate; the parts form a take-up return spring assembly and are rigidly connected with an assembly cable take-up device through a fastening screw, so that the free take-up and pay-off movement of the flat cable is realized.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a hidden cable coil spring take-up pretightening structure, in particular to a hidden cable coil spring take-up pretightening structure for medical X-ray machines with self-locking characteristics. Background technique [0002] At this stage, the C-arm motion cable of the mobile C-arm X-ray machine generally adopts the plug-in method, such as figure 1 As shown, the technical difficulty and cost of this method are relatively low. However, there are certain defects and deficiencies in the functional level and clinical application of surgery. It is mainly reflected in the following aspects: the external cable affects the overall consistency of the equipment and cannot make the appearance of the equipment simple and uniform. Secondly, because the external cables are exposed, the mobile performance of the equipment in a small operating room is limited, and there is also the ri...

Problems solved by technology

It is mainly reflected in the following aspects: the external cable affects the overall consistency of the equipment and cannot make the appearance of the equipment simple and uniform

Secondly, because the external cables are exposed, the mobile performance of the equipment in a small operating room is limited, and there is also a risk of collision and interference between the cables and the patient, surgical instruments and their own movement

Furthermore, the external cable also limits the flexibility and range of movement of the mechanism during 3D scanning
