Abstract

The invention discloses a bulb tube locking mechanism. The mechanism comprises a mounting frame, a roller, a magnet sucker, and an electromagnet assembly, wherein a roller shaft and guide columns arearranged on the mounting frame, and the guide columns are parallel to the roller shaft; the roller is rotationally arranged on the roller shaft; the magnet sucker is fixed on the side of the roller; and the electromagnet assembly is movably arranged on the guide column and is suitable for moving along the guide column and abutting against the magnetic chucker in the power-on state. The invention further provides a bulb tube lifting device. According to the bulb tube locking mechanism disclosed by the invention, the magnet sucker is arranged on the side face of an idler wheel, the electromagnetmoves along the guide column and is attracted to the magnet sucker according to the principle that the electromagnet is powered on to generate magnetic force, the effect of fixing the idler wheel isachieved; and the bulb tube locking mechanism has the advantages of being easy and convenient to operate and the like, and the locking positioning accuracy is greatly improved.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a tube locking mechanism and a tube lifting device. Background technique

[0002] The wire rope lifting device used in the lifting process of the medical X-ray tube usually uses one end of the wire rope to connect the tube assembly, and the other end to bypass the roller to connect the counterweight, so as to realize the stable lifting of the control ball rod assembly. During the use of the lifting device, the tube assembly is usually adjusted by manpower and other external forces to move the tube assembly to a specified height, and the rotation of the roller is prevented by a locking structure or a limit switch to achieve the locking effect. In the process of fixed locking, the limit switch has problems such as cumbersome operation and difficulty in starting and stopping, resulting in inaccurate locking positioning, while the traditional electromagnet locking structure h...
