[0021] Reference Figure 2 The inner wall of the main protective plate 1 is fixedly connected with a plurality of sliding rods 7, the rod body of the sliding rod 7 is slidably connected to the auxiliary protective plate 2, the rod body of the sliding rod 7 is slidably connected with a push plate 8, and the rear end of the push plate 8 is fixedly connected with a plurality of first springs 9, and the other end of the first spring 9 is fixedly connected to the inner wall of the main protective plate 1. When the block 13 no longer fixes the auxiliary protective plate 2, the auxiliary protective plate 2 can be pushed by the elastic force of the first spring 9, so that the auxiliary protective plate 2 can be conveniently moved. At the same time, the sliding rod 7 can limit the movement of the auxiliary protective plate 2.

[0022] Reference Figure 2 The inner top surface and the inner bottom surface of the main protective plate 1 are provided with limiting grooves, and one side of the upper surface and the lower surface of the auxiliary protective plate 2 are fixedly connected to the limiting block 10, and the outer wall of the limiting block 10 is slidably connected to the limiting groove. The limiting block 10 can prevent the auxiliary protective plate 2 from moving out of the interior of the main protective plate 1.

[0023] Reference Figure 3 The front end of the rotating rod 4 is fixedly connected with a rotating handle 6. The rotating handle 6 can be used to conveniently rotate the rotating rod 4, thereby driving the gear 5 to rotate on the surface of the latch tooth 3. The latch tooth 3 and the gear 5 are meshed with each other, thereby driving the auxiliary protective plate 2 to move on the inner wall of the main protective plate 1.

[0025] The implementation principle of the radiation-proof lead screen in the embodiment of the present application is as follows: when in use, the pull rod 12 can be pulled by the pull plate 15 to make the block 13 move away from the inside of the fixed groove, and then the turning rod 4 can be rotated by the turning handle 6, thereby driving the gear 5 to rotate on the surface of the clamping tooth 3, and the clamping tooth 3 and the gear 5 are meshed with each other, thereby driving the secondary protective plate 2 to move on the inner wall of the main protective plate 1 to adjust the length of the screen. At the same time, with the cooperation of the sliding rod 7, the pushing plate 8 and the first spring 9, when the block 13 no longer fixes the secondary protective plate 2, the secondary protective plate 2 can be pushed by the elastic force of the first spring 9, so that the secondary protective plate 2 can be conveniently moved. When it moves to a suitable position, under the elastic force of the second spring 14, the block 13 can be inserted into the inside of the fixed groove on the secondary protective plate 2, thereby fixing the position of the secondary protective plate 2. Universal wheels are provided at the lower ends of the main protective plate 1 and the secondary protective plate 2, which can facilitate the movement of the screen.
