Description

Anti-collision device of X-ray tube assembly

Technical Field

The utility model relates to the technical field of medical equipment, in particular to an anti-collision device of an X-ray tube assembly.

Background

The X-ray tube component can generate X-rays for medical imaging, is arranged at a specific part of the medical equipment, can irradiate different directions and parts through a certain motion track to obtain images of different directions and parts, and can obtain two-dimensional or three-dimensional medical images with different use requirements through computer image processing.

Other objects or persons may be accidentally encountered during movement of the X-ray tube assembly to cause damage or injury. The current solutions to the problem of damage or injury to such moving parts typically stop the movement of the moving or driving part by manually controlling an emergency stop switch. The measures require an equipment operator to closely observe the motion state of the equipment in real time, and once collision possibly occurs, the equipment operator needs to press an emergency stop switch of the equipment in time to stop the equipment from moving. Such measures have the disadvantage of requiring a high degree of attention from the operator of the apparatus during the movement of the apparatus and of possibly not being able to prevent an accidental collision of the X-ray tube assembly in time due to human factors of the operator of the apparatus.

Furthermore, the mounting seat is a hollow square body, the bottom surface of the mounting seat is provided with an opening matched with the beam outlet of the beam outlet frame, the side surface of the mounting seat is provided with a square window, and the middle part of the square window is provided with a horizontal support; and four corners of the mounting seat are provided with spring through holes.

And furthermore, a square window matched with the opening at the top of the mounting seat is formed in the center of the supporting plate, and mounting holes matched with the spring through holes are formed in the supporting plates at four corners of the square window.

Furthermore, a compression spring is installed on the installation hole, and the top end of the compression spring is connected with the anti-collision shell; the bottom end of the compression spring extends into the bottom of the spring through hole,

and furthermore, studs are symmetrically fixed on the edge of the supporting plate at one side of the square window through two locking nuts, and the studs penetrate through the square window and the horizontal support and are fixed at the bottom of the mounting seat.

And furthermore, an opening with the size consistent with that of the square window is formed in the top of the anti-collision shell.

The utility model has the beneficial effects that:

the device ensures collision protection of the X-ray tube component in the moving forward direction through the micro switches distributed on the circumference and the compression springs positioned axially; and set up compression spring respectively in four positions between anticollision shell and mount pad, played better buffering and the effect that resets, its simple structure, simple to operate simultaneously.

In conclusion, no matter the X-ray tube assembly touches the anti-collision shell in any moving forward direction, the anti-collision signal can be triggered, and the X-ray tube assembly can stop running quickly, so that an effective protection effect is achieved; meanwhile, the structure is simple and the installation is convenient.
