Description

Technical Field

[0001] The present application relates to the technical field of medical radiation protection, and in particular to a medical radiation protection lead plate overlapping device. Background Art

[0002] Medical radiation protection lead sheet is a special material used to prevent radiation. It is usually made of lead, which has a high density and ability to absorb radiation. Medical radiation protection lead sheet is often used in medical equipment and protective facilities such as X-ray rooms and nuclear medicine laboratories.

[0003] Since the lead plate is heavy, it is obviously inconvenient and unreasonable to use a whole piece of lead plate for radiation protection, so it is necessary to overlap multiple radiation protection lead plates to make them have the effect of radiation protection. In the process of overlapping, there is a gap between the two lead plates, which loses its radiation protection effect. The traditional splicing method is to place a lead plate in the gap between two adjacent lead plates and then fix it with a fixing device. This method requires transporting multiple lead plates of different sizes, and it is cumbersome to use and not practical. Therefore, in order to solve the above problems, the present application provides a medical radiation protection lead plate overlapping device.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the problem of gaps existing at the overlap of two lead plates, the present application provides a medical radiation protection lead plate overlap device.

[0006] The present application provides a medical radiation protection lead plate overlapping device, comprising a lead plate and an overlapping plate, wherein the cross-section of the overlapping plate is two mirror-symmetrical rhombuses, the left and right side walls of the overlapping plate are provided with slots, the lower ends of the side walls of the slots close to the center of the overlapping plate are provided with sliding slots, and the slots are provided with limit plates with the same height as the overlapping plate, and both ends of the lead plate are bent, and the bent parts can slide into the slots and be fixed by the limit plates.

[0007] Preferably, the limiting plates are all slidably connected to the overlapping plates via the sliding grooves, and the limiting plates are all elastically connected to the side walls of the slots via a plurality of vertically arranged springs.

[0008] Preferably, the two limiting plates are non-mirror symmetrical in the horizontal plane.

[0009] Preferably, the lower part of the lap plate is a cavity, a rotating rod is arranged through the lap plate and rotatably connected, the lower end of the lap plate is rotatably connected to the lower wall of the cavity, and the outer wall of the lap plate located in the cavity is sleeved with a gear coaxially fixedly connected thereto.

[0010] Preferably, a sliding block is slidably connected in each of the sliding grooves, one end of the sliding block is fixedly connected to the limiting plate, and the other end of the sliding block is fixedly connected to a rack.

[0011] Preferably, the rack is slidably connected to the lower wall of the lower cavity of the lap plate, and the rack is meshingly connected to the gear.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] The rotation of the rotating rod drives the rotation of the gear, and the two racks meshing with the gear also begin to move. The limit plate fixedly connected to the rack slides through the sliding groove, and the spring is compressed while the limit plate is separated from the side wall of the slot. The lead plate can be inserted into the slot, and the gap between the two lead plates is covered by the lead overlapping plate. At the same time, the overlapping plate faces the direction of radiation propagation as an inclined surface, which can reflect the radiation to a certain extent. After the lead plate is inserted into the slot, the rotating rod is released, and under the action of multiple springs, the limit plate moves to clamp the lead plate. Compared with the traditional device, this device can quickly overlap the lead plates and cover the gaps at the overlaps. The design of the inclined surface of the overlapping plates also has a certain weakening effect on the radiation. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] Embodiment 1

[0020] Reference Figure 1-3A medical radiation protection lead plate overlap device includes a lead plate 1 and an overlap plate 2. The cross section of the overlap plate 2 is two mirror-symmetrical rhombuses. The left and right side walls of the overlap plate 2 are provided with slots 3. The lower end of the side wall of the slot 3 near the center of the overlap plate 2 is provided with a sliding slot 9. The slot 3 is provided with a limit plate 7 with the same height as the overlap plate 2. Both ends of the lead plate 1 are bent, and the bent part can slide into the slot 3 and be fixed by the limit plate 7. A certain bending angle at both ends of the lead plate 1 can be obtained by calculation. After the lead plate 1 at this angle is fixed, the two lead plates 1 can be in the same vertical plane. The limit plates 7 are slidably connected to the overlap plate 2 through the sliding slot 9, and the limit plates 7 are elastically connected to the side walls of the slot 3 through a plurality of vertically arranged springs 8.

[0021] The lower part of the lap plate 2 is a cavity, and a rotating rod 4 is provided through the lap plate 2 and rotatably connected. The lower end of the lap plate 2 is rotatably connected to the lower wall of the cavity, and the outer wall of the lap plate 2 located in the cavity is sleeved with a gear 5 coaxially fixedly connected thereto. Slide blocks are slidably connected in the sliding grooves 9, one end of the slide blocks is fixedly connected to the limit plate 7, and the other end is fixedly connected to the rack 6. The rack 6 is slidably connected to the lower wall of the cavity at the lower part of the lap plate 2, and the rack 6 is meshedly connected to the gear 5. The two limit plates 7 are non-mirror symmetrical in the horizontal plane, so that the limit plates 7 on both sides can be separated from the slot 3 without interference by rotating the gear 5 alone.

[0022] Rotating the rotating rod 4 drives the gear 5 to rotate, and the two racks 6 meshing with the gear 5 also start to move. The limit plate 7 fixedly connected to the rack 6 slides through the sliding groove 9, and while compressing the spring 8, the limit plate 7 is separated from the side wall of the slot 3, so that the lead plate 1 can be inserted into the slot 3. The gap between the two lead plates 1 is covered by the lead lap plate 2. At the same time, the lap plate 2 is an inclined surface facing the direction of radiation propagation, which can reflect the radiation to a certain extent. After the lead plate 1 is inserted into the slot 3, the rotating rod 4 is released. Under the action of multiple springs 8, the limit plate 7 moves to clamp the lead plate 1, thereby quickly lap-jointing the lead plate 1.

[0023] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
