[0001] The utility model relates to the technical field of radiation protection buildings, in particular to a shielding component of a particle therapy radiation protection building. Background Art

[0002] Particle therapy is a tumor treatment method that uses high-energy particle beams to kill cancer cells. Because particle therapy produces high radiation, it poses a radiation risk to equipment operators, patients and other personnel, so the treatment equipment must be placed in a radiation-proof building. Generally, radiation-proof buildings are composed of concrete walls, metal shielding layers, etc.

[0003] Building components are the various components of the main body of a building, including beams, columns, walls, etc., as well as other components such as parts that connect the various parts.

[0004] Now we search for the Chinese patent movable modular radiation shielding wall, publication number CN207602236U, the shielding wall includes a main frame, a shielding plug plate, a shielding plug plate slot, a longitudinal fixing groove of the universal wheel center axis, a longitudinal fixing groove of the universal wheel guide shaft, a universal wheel, a universal wheel guide shaft, a guide shaft connecting shaft, a universal wheel crowbar, a control panel touch screen mounting platform, a sensor mounting platform, a camera mounting platform, and a handle. The effect of the utility model is that the shielding wall is used for experiments or construction sites that need to shield light, heat, electromagnetic, nuclear radiation, etc. It is movable, modular, and can match various on-site operations. The automated information collection system of the shielding wall can accurately grasp various information indicators on the site in real time.

[0005] However, it still has the following disadvantages in actual use:

[0006] When installing the shielding plug-in plate, because the shielding plug-in plate is made of metal and has a certain weight, the installer needs to spend a lot of effort to operate it, and the installation is extremely difficult. In addition, when the shielding plug-in plate is inserted into the slot, the friction force on the inner wall of the slot is large, which may also cause damage to the inner wall of the slot and the shielding plug-in plate.

[0007] Therefore, we provide a shielding component for a particle therapy radiation protection building to solve the above problems. Utility Model Content

[0008] The purpose of the utility model is to provide a shielding component for a particle therapy radiation protection building to solve the problem raised in the above-mentioned background technology that when installing a shielding plug plate, because the shielding plug plate is made of metal and has a certain weight, it requires the installer to spend a lot of effort to operate it, and the installation is extremely difficult. In addition, when the shielding plug plate is inserted into the slot, the friction force on the inner wall of the slot is relatively large, which will also cause damage to the inner wall of the slot and the shielding plug plate.

[0009] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0010] The utility model relates to a shielding component for a particle therapy radiation protection building, comprising:

[0011] A main body component, including a shielding plug board arranged, and the shielding plug board is a lead plate;

[0012] A moving component, including a first groove opened on the side of the shielding plug board, a fixing plate connected to the inner side of the first groove, a first movable groove opened on the fixing plate, a second movable groove opened on the fixing plate, a third movable groove opened on the fixing plate, a telescopic block movably connected to the upper end of the fixing plate, a rotating shaft movably connected to the first movable groove, and a roller rotatably connected to the middle of the rotating shaft;

[0013] A filling component, connected to the shielding plug board.

[0014] Further, there are two groups of the moving components, which are respectively connected to the left and right sides of the lower end of the shielding plug board;

[0015] Specifically, two groups of moving components are provided, which are respectively located on both sides of the lower end of the shielding plug board, facilitating the stability when the shielding plug board moves.

[0016] Further, the first movable groove penetrates through the second movable groove, and the second movable groove penetrates through the third movable groove;

[0017] Specifically, when the rotating shaft is located in the first movable groove, the roller is retracted in the first groove. When the rotating shaft moves from the first movable groove through the second movable groove to the third movable groove, the roller extends out of the first groove. When pushing the shielding plug board, the roller can be driven to rotate, reducing the resistance during movement.

[0018] Further, the rotating shaft is movably connected in the second movable groove and the third movable groove;

[0019] Specifically, the rotating shaft moves in the first movable groove, the second movable groove and the third movable groove, and two functions of roller movement and storage can be realized.

[0020] Further, the main body component further includes an observation window connected to the middle of the shielding plug board, and the observation window is a transparent lead glass;

[0021] Specifically, the situation in the treatment room can be observed through the observation window. Since there is radiation during treatment, the observation window is also a lead glass with radiation protection function.

[0022] Further, the filling component includes a second groove opened on the top of the shielding plug board, a spring connected to the second groove, and a shielding block connected to the other end of the spring, and the shielding block is movably connected in the second groove;

[0023] Specifically, the second groove provides a movable space for the shielding block, and the provided spring facilitates the shielding block to shrink and spring outward.

[0024] Furthermore, the filling assembly further comprises a limit block connected to the top side of the shielding plug plate, a slider movably connected to the limit block, and the slider movably connected to the shielding block;

[0025] Specifically, press the shielding block into the second groove, push the slider in the limit block, so that the slider is pressed on the shielding block to facilitate the movement of the shielding plug-in plate. When the shielding plug-in plate is completely moved into the slot, move the slider back to its original position, and the shielding block can spring up to fill the gap between the slot and the shielding plug-in plate without affecting the overall radiation protection function.

[0026] Compared with the prior art, the advantages of the present invention are:

[0027] The utility model provides a first groove for placing a fixed plate and storing rollers, and provides a first movable groove, a second movable groove and a third movable groove, which cooperate with the rotating shaft to realize two states of roller retracting and extending, so as to facilitate moving the shielding plug plate. At the same time, after installing the shielding plug plate, the rollers can be retracted without affecting the shielding effect of the shielding plug plate.

[0028] Based on the first beneficial effect, by setting a telescopic block, and the telescopic block having an arc-shaped outer side, it is convenient to install the rotating shaft and the roller into the first movable groove.

[0029] The utility model can fill the redundant space in the slot by means of the second groove, the shielding block and the spring, thereby avoiding the shielding effect being affected by the existence of the gap.

[0030] Based on the third beneficial effect, by setting the limit block and the slider, when installing the slot, the shielding block can be pressed down to avoid affecting the installation. After the installation is completed, the slider is moved back to make the shielding block pop up.

[0031] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings. Example 1

[0045] See also Figure 1-3As shown, this embodiment is a shielding component of a particle therapy radiation protection building, including:

[0046] The main body assembly includes a shielding plug plate 10 which is a lead plate, and an observation window 11 connected to the middle of the shielding plug plate 10 which is a transparent lead glass;

[0047] There are two groups of moving components, which are respectively connected to the left and right sides of the lower end of the shielding plug plate 10, including a first groove 20 opened on the side of the shielding plug plate 10, a fixed plate 21 connected to the inner side of the first groove 20, a first movable groove 22 opened on the fixed plate 21, a second movable groove 23 opened on the fixed plate 21, a third movable groove 24 opened on the fixed plate 21, a telescopic block 27 movably connected to the upper end of the fixed plate 21, a rotating shaft 25 movably connected in the first movable groove 22, and a roller 26 rotatably connected to the middle of the rotating shaft 25;

[0048] The first movable groove 22 penetrates the second movable groove 23, and the second movable groove 23 penetrates the third movable groove 24;

[0049] The rotating shaft 25 is movably connected in the second movable groove 23 and the third movable groove 24 .

[0050] Use of mobile components:

[0051] The rotating shaft 25 is pushed from the telescopic block 27 into the first movable groove 22 in the first groove 20. The telescopic block 27 is pushed back into the fixed plate 21 by the pushing force of the rotating shaft 25. When the rotating shaft 25 moves into the first movable groove 22, the telescopic block 27 pops up to prevent the rotating shaft 25 from moving out of the first movable groove 22. After the rotating shaft 25 moves through the second movable groove 23 to the third movable groove 24, the shielding plug board 10 moves into the slot. Under the action of the gravity of the shielding plug board 10, the rotating shaft 25 is clamped in the third movable groove 24. In the movable groove 24, the shielding plate 10 moves and drives the roller 26 to rotate, which can reduce the labor intensity of the installer and reduce the wear on the inner wall of the slot and the shielding plate 10. When the shielding plate 10 is completely moved into the slot, lift a corner of the first movable groove 22 to make the roller 26 separate from the bottom surface of the slot, and then move the roller 26 to drive the rotating shaft 25 from the third movable groove 24 back to the first movable groove 22, and then put down the shielding plate 10. At this time, the bottom surface of the shielding plate 10 is in contact with the bottom surface of the slot. Example 2
