The side of the fixed column 10 is sleeved with a first spring 12. The first adjustment frame 1 and the second adjustment frame 4 are pushed to the specified position through the fixed column 10 installed at the bottom. When the protection range needs to be increased, the limit block 9 on the side of the first adjustment frame 1 is first pulled out, and the adjustment column 6 is pressed to shrink the first spring 12, driving the multiple fixing bars 26 to move downward, and the second spring 25 is squeezed and contracted, thereby driving the limit bead 27 to separate from the active cavity 23. At this time, the second adjustment frame 4 can be dragged to drive the second connecting column 22 and the second protective lead plate 8 to slide, increasing the protection range. Add the area covered by the second protective lead plate 8, move to the appropriate position and then release the adjusting column 6. The first spring 12 is released and rebounds due to the elastic force, driving the adjusting column 6 to return to its original position, and the limiting block 9 is inserted into the groove opened on the side of the adjusting column 6 to limit the adjusting column 6. The device will not shrink due to accidental touch or pressure.

This increases the protection range and enables the adjusting frame to adapt to different protection ranges.

[0025] The working principle is as follows: when the radiation protection device of the nuclear medicine department needs to be used, the first adjustment frame 1 and the second adjustment frame 4 are pushed to the specified position through the fixed column 10 installed at the bottom. When the protection range needs to be increased, the limit block 9 on the side of the first adjustment frame 1 is first pulled out, and the adjusting column 6 is pressed to shrink the first spring 12, driving the multiple fixing bars 26 to move downward, and the second spring 25 is squeezed and contracted, thereby driving the limit bead 27 to separate from the active cavity 23. At this time, the second adjusting frame 4 can be dragged to drive the second connecting column 22 and the second protective lead plate 8 to slide, thereby increasing the area blocked by the second protective lead plate 8. After moving to the appropriate position, the adjusting column 6 is released, and the first spring 12 is released and rebounds by the elastic force, driving the adjusting column 6 to return to its position, and the limit block 9 is inserted into the groove opened on the side of the adjusting column 6 to limit the adjusting column 6. The device will not shrink due to accidental touch and pressing. After the adjusting column 6 returns to its position, the elastic force of the second spring 25 is released and expanded, driving the limit bead 27 to rebound into the active cavity 23, fixing the position of the second connecting column 22, and completing the second The elongation of the protective lead plate 8 increases the protection range. When the height of the first adjustment frame 1 needs to be adjusted, the block 34 on the side of the first adjustment frame 1 can be pulled to stretch the third spring 35, separate the block 34 from the side groove 33, release the limit on the base 32, and release the block 34 after the base 32 is pulled out to a suitable distance. The block 34 is returned to its original position by the elastic force of the third spring 35 and is inserted into the side groove 33 to fix the position of the base 32. The base 32 is supported by the bottom of the first adjustment frame 1 and the second adjustment frame 4. When the length of the first adjustment frame 1 and the second adjustment frame 4 needs to be increased, the rotating connector 5 can be used to connect another first adjustment frame 1, and the distance between the two adjacent first adjustment frames 1 and the second adjustment frames 4 can be adjusted by the rotating connector 5. When idle, the second protective lead plate 8 of the first adjustment frame 1 can be put into the first protective lead plate 7, and the adjacent first adjustment frame 1 and the second adjustment frame 4 can be folded by the rotating connector 5, thereby reducing the space occupied by the first adjustment frame 1 and improving the applicability of the radiation protection device.

[0026] Example 2: Figure 2 and 5As shown, the extension mechanism 3 includes a slide groove 31 opened in the first adjustment frame 1, a base 32 is slidably installed in the slide groove 31, a plurality of side grooves 33 are opened on the side of the base 32, a stopper 34 is installed on the side of the first adjustment frame 1, and a third spring 35 is symmetrically installed on the side of the stopper 34, and the stopper 34 is adapted to the side groove 33. A rotating connecting member 5 is opened between the first adjustment frame 1 and the second adjustment frame 4, and a universal wheel 13 is opened at the bottom of the first adjustment frame 1 and the second adjustment frame 4. Adjusting the first adjustment frame When the height of the frame 1 is adjusted, the block 34 on the side of the first adjustment frame 1 can be pulled to stretch the third spring 35, separate the block 34 from the side groove 33, release the limit on the base 32, and release the block 34 after the base 32 is pulled out to a suitable distance. The block 34 is returned to its original position by the elastic force of the third spring 35 and is inserted into the side groove 33 to fix the position of the base 32.
