[0002] In imaging centers and radiology departments of hospitals, metal radiation protection doors are usually used to block radiation to prevent radiation leakage and ensure the health and safety of medical staff and patients. Modern hospitals are busy, and radiation protection doors often need to be opened and closed frequently. Existing radiation detection equipment is not linked to the door structure. When the radiation door is opened, the radiation equipment is not powered off, but is temporarily manually closed, which will cause radiation risks. To this end, we proposed a chain radiation protection device. Utility Model Content

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] An interlocking radiation protection device, see Figure 1-4 , including a door frame 1, a rotating part 2 is connected to one end of the door frame 1, and a trigger part 3 is arranged on a side of the door frame 1 close to the rotating part 2. The radiation proof door is fixedly connected to the door frame 1, and the door frame 1 moves laterally to drive the radiation proof door to open and close. When the door frame 1 moves toward the trigger part 3, the radiation proof door opens, and the rotating part 2 rotates with the movement of the door frame 1 so that the trigger part 3 is triggered, thereby improving the safety of the radiation proof door when it is opened.

[0026] The rotating member 2 includes a first plate segment 21 and a second plate segment 22, wherein the end of the first plate segment 21 is bent to form a movable hook 211, a pressure plate 212 is provided on the side of the first plate segment 21, and a roller 23 is fixed to the end of the second plate segment 22;

[0027] The trigger member 3 at least includes a back plate 31, on which a wedge-shaped guide block 32 is fixed on the side of the back plate 31 facing the door frame 1, a static hook claw 33 and a trigger switch 34 are fixed on the back plate 31, and the trigger switch 34 is connected in series in the power supply circuit of the radiation device. When the door frame 1 moves laterally toward the trigger member 3, the rotating member 2 rotates accordingly and drives the pressure plate 212 to rotate. The pressure plate 212 presses the trigger switch 34 to disconnect it. When the roller 23 moves against the wedge-shaped guide block 32, the moving hook claw 211 can be rotatably connected with the static hook claw 33, thereby improving the lateral limit of the door frame 1, improving the stability of the door frame 1 after opening, and ensuring that the trigger switch 34 is in the disconnected state.

[0028] The trigger switch 34 in the utility model includes a fixed block 341, which is fixed on the back plate 31, and an insulating plate 347 and a conductive plate 346 are fixed on the fixed block 341, wherein a conductive spring 342 and a first terminal 343 are fixed on the insulating plate 347 by screws, and a fixing plate 344 and a second terminal 345 are connected to the conductive plate 346. When the spring plate 342 is not compressed, the spring plate 342 and the fixing plate 344 are in a tightly fitted passage state, and the first terminal 343 and the second terminal 345 are respectively electrically connected in series in the power-on circuit of the radiation device through the terminal and the wire. When the spring plate 342 is compressed, the spring plate 342 and the fixing plate 344 are disconnected to open the power-on circuit of the radiation device, thereby improving safety.

[0029] Among them, an insulating block 24 is fixed on the pressure plate 212. When the rotating member 2 rotates, the pressure plate 212 and the insulating block 24 are driven to rotate. The insulating block 24 presses on the spring sheet 342 to separate the spring sheet 342 and the fixed sheet 344, which is safer. In addition, the surfaces of the rotating member 2, the roller 23, the moving hook 211, the static hook 33, and the back plate 31 can be coated with an insulating layer or made of insulating non-metallic materials.

[0030] In order to improve the stability of the connection between the moving hook 211 and the static hook 33, a self-resetting moment switch 36 is also fixed on the back plate 31, a transverse plate 11 is fixed at the end of the door frame 1, and an electromagnet 4 is fixed on the transverse plate 11. The first plate section 21 is provided with an armature 5 on the side facing the electromagnet 4, and the electromagnet 4 and the self-resetting moment switch 36 are electrically connected in series. When the door frame 1 drives the rotating member 2 to move laterally toward the trigger member 3, the first plate section 21 moves toward the static hook 33, and the pressure plate 212 presses on the self-resetting moment switch 36 to close the self-resetting moment switch 36. The electromagnet 4 is energized, and the electromagnet 4 is attracted by the armature 5, so that the rotating member 2 can be stably attracted and fixed, and the static hook 33 is stably connected with the moving hook 211. On the one hand, it limits the lateral movement and opening of the door frame 1, and on the other hand, it ensures that the spring piece 342 is compressed and is in a stable separation state with the fixing piece 344, and the trigger switch 34 remains disconnected, thereby improving safety and reliability.

[0031] A remote manually controllable switch is also connected in series to the connection circuit between the self-resetting inching switch 36 and the electromagnet 4. By disconnecting the remote switch, the electromagnet 4 can be disconnected to loosen the movable hook 211 and the static hook 33.

[0032] The first plate section 21 and the second plate section 22 are bent and tilted at an acute angle, and the bending position is connected to the door frame 1 for rotation. The wedge-shaped guide block 32 gradually tilts upward from the side close to the door frame 1 to the side. A limit plate 35 is also fixed on the back plate 31, and a limit column 6 is fixed on the first plate section 21. When the rotating member 2 moves toward the trigger member 3 along with the door frame 1, the roller 23 contacts the top of the wedge-shaped guide block 32 and is gradually lifted. The rotating member 2 rotates. At this time, the limit column 6 moves to the top of the limit plate 35. The rotating member 2 can only rotate upward in one direction until the pressure plate 212 presses on the spring 342 and the self-reset inching switch 36.

[0033] In addition, a limiting angle block 12 is fixed on the door frame 1 , and the limiting angle block 12 limits the maximum downward rotation angle of the rotating member 2 , and the height of the roller 23 is always higher than the lowest side of the wedge-shaped guide block 32 .

[0034] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary personnel in the field to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents of the present invention for protection have been fully recorded in the claims.
