[0022] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] Example 1

[0024] This embodiment provides a foldable radiation-proof lead screen. Figure 1-6 As shown, the foldable radiation-proof lead screen includes a screen body 1, with screen bodies 2 rotatably connected to both sides of the screen body 1, multiple sets of universal wheels 3 are provided at the bottom of the screen body 1 and the screen body 2, and an extension mechanism 4 is provided at the bottom of the screen body 2;

[0025] When in use, the radiation protection area of the screen can be increased by the provided extension mechanism 4. The operation is simple and quick, the use is convenient, and the folding and fixing is convenient. The operation is simple and quick, and the screen is easy to move.

[0026] Specifically, the extension mechanism 4 includes an operating frame 41 fixedly connected to the bottom of the screen body 2, a servo motor 42 is provided inside the operating frame 41, the output end of the servo motor 42 extends to the inside of the operating frame 41 and is fixedly connected to a reciprocating screw 43, the reciprocating screw 43 is rotatably connected to the inside of the operating frame 41, a moving block 44 is provided on the outside of the reciprocating screw 43, the top of the moving block 44 is fixedly connected to an extension screen 45, and the extension screen 45 is provided inside the screen body 2;

[0027] During use, the servo motor 42 drives the reciprocating screw 43 to rotate inside the operating frame 41. The reciprocating screw 43 is threadedly connected to the moving block 44 set on the outside, so that the moving block 44 drives the extended screen 45 to move, which can increase the radiation protection area of the screen. The operation is simple, fast and easy to use.

[0028] Furthermore, the reciprocating screw 43 is threadedly connected to the moving block 44, and the moving block 44 is arranged inside the operating frame 41, and the moving block 44 is slidingly connected to the operating frame 41. Through the threaded connection between the reciprocating screw 43 and the moving block 44, the moving block 44 can be forced to slide inside the operating frame 41, thereby improving the stability of the movement of the operating frame 41.

[0029] Example 2

[0030] The difference from Example 1 is that when the screen is folded and moved, it cannot be fixed after folding, which will cause shaking during the movement. For this reason, the extension mechanism 4 also includes a connecting block 46 fixedly connected to the side of one group of screen main bodies 2 and a plug-in slot block 48 fixedly connected to the side of another group of screen main bodies 2. One end of the connecting block 46 is fixedly connected with a plug-in block 47, which is adapted to the plug-in slot block 48, and the plug-in block 47 is plugged into the plug-in slot block 48. By rotating and folding the two groups of screen main bodies 22 toward the screen main body 1, the two groups of screen main bodies 22 respectively drive the connecting block 46 and the plug-in slot block 48 to move toward each other, so that the plug-in block 47 set at one end of the connecting block 46 is plugged into the inside of the plug-in slot block 48. The two groups of screen main bodies 22 can be fixed to the side of the screen main body 1, which is convenient for folding and fixing. The operation is simple and quick, and it is easy to move and easy to use.

[0031] Specifically, a fixing rod 49 is provided inside the plug-in block 47, and fixing holes 50 that are compatible with the fixing rod 49 are opened on both sides of the plug-in slot block 48. The fixing rod 49 is plugged into the fixing hole 50. By pressing the fixing rod 49, the two groups of fixing rods 49 enter the interior of the plug-in block 47, so that the plug-in block 47 can be plugged into the interior of the plug-in slot block 48. The two groups of fixing rods 49 are plugged into the fixing holes 50 opened on both sides of the plug-in slot block 48, so that the plug-in block 47 can be fixed inside the plug-in slot block 48. The operation is simple and quick, and it is convenient to fix and disassemble, and easy to use.

[0032] Furthermore, the fixing rods 49 are symmetrically arranged inside the plug-in block 47, and one end of the two groups of fixing rods 49 arranged inside the plug-in block 47 is fixedly connected to a sliding plate 51, and a spring 52 is fixedly connected between the two groups of sliding plates 51. By pressing the two groups of fixing rods 49, the fixing rods 49 push the sliding plate 51 set on the side to move, and the sliding plate 51 compresses the spring 52 set on the side. The rebound force of the spring 52 facilitates the restoration of the fixing rods 49 to its original state, which is convenient for use.

[0033] Furthermore, a limiting rod 53 is provided inside the plug-in block 47, and two sets of sliding plates 51 are provided outside the limiting rod 53, and the sliding plates 51 are slidably connected to the limiting rod 53. The sliding plates 51 slide outside the limiting rod 53 under force, and the setting of the limiting rod 53 can improve the stability of the movement of the sliding plates 51.

[0034] It should be noted that the servo motor 42 is an existing device, and its working principle, size and model are irrelevant to the function of this application, so no further description is given. The control method of the present invention is controlled by a controller, and the control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present invention is mainly used to protect mechanical devices, so the present invention no longer explains the control method and circuit connection in detail.

[0035] The above are only preferred specific implementation methods of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solutions and concepts of the present application within the technical scope disclosed in the present application, which should be covered by the scope of protection of the present application.
