[0028] Example 2

[0029] Based on Example 1, a preferred embodiment of the storage box for brachytherapy afterloading equipment provided by the present invention is as follows: Figures 1 to 5As shown: a storage box 2 is fixedly connected to the middle of the top of the support frame 1, and the support frame 1 plays a fixed supporting role for the storage box 2. The bottom end of the inner wall of the storage box 2 is fixedly connected to uniformly distributed damping rods 6 in order to further improve the stability of the damping rods 6.

[0030] In this embodiment, the telescopic end of the damping rod 6 is fixedly connected to the support block 7, and the damping rod 6 has a fixing effect on the support block 7. The top ends of multiple support blocks 7 are fixedly connected to the same storage plate 22, and the support block 7 has a fixing and supporting effect on the storage plate 22.

The threaded blocks 16 drive the articulated frame 17 to move during the movement, and further drive the articulated frame 2 19 to move through the connecting rod 18, so that the guide plate 20 slides on the bottom end of the inner wall of the support frame 1, and drives the universal wheel 21 to move up and down, so that it is retracted into the support frame 1. At this time, the support frame 1 is connected and reinforced with the contact surface to increase the friction with the contact surface, reduce the shaking or tilting of the box body caused by external vibration or movement, and make the overall structure more stable. When the equipment is stored, the equipment It falls on the storage plate 22, thereby generating a certain degree of impact force on the storage plate 22 and causing it to move downward. The downward movement of the storage plate 22 drives the support block 7 to move downward, and further drives the connecting frame 8 to rotate, causing it to slide inside the buffer slide groove 9, and the damping rod 6 and the buffer spring 11 are both forced to contract. After the buffer spring 11 contracts to a certain extent, it rebounds by its own elastic force, and drives the connecting frame 8, the support block 7 and the storage plate 22 to reset. At this time, the internal friction force of the damping rod 6 can effectively slow down the reset speed of the buffer spring 11, thereby achieving a buffering effect on the storage plate 22, being able to effectively absorb external shocks and vibrations, and reducing the force on the radiotherapy equipment inside the storage box, thereby protecting the safety of the equipment and further extending its service life.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
