Description

Technical Field

[0001] The utility model relates to the technical field of radiation protection, in particular to a radiation protection lead plate structure. Background Art

[0002] Lead plate refers to a plate rolled from metal lead. It is a common radiation protection material and is generally used in X-ray rooms and CT rooms in hospitals for radiation protection.

[0003] The common thickness of lead plates is 0.5-500mm, and the widest lead plates produced by factories are 2000mm. Generally, the width of a single wall in a hospital CT room is greater than two meters, and therefore multiple lead plates cut into squares are required to be spliced ​​along the width direction to meet usage requirements.

[0004] The inventors learned that in the prior art, in order to fix the lead plate to the structural layer in the wall, two adjacent lead plates are partially overlapped, and bolts need to be passed through the lead plates at the overlapped joints, which requires through holes to be preset or drilled on site on the lead plates. The through hole positions cannot effectively attenuate radiation, which easily affects the overall radiation protection performance of the lead plate. Utility Model Content

[0005] The utility model provides a radiation-proof lead plate structure, which can at least solve one of the above-mentioned technical problems.

[0006] In order to solve the above-mentioned technical problems, one or more embodiments of the utility model provide a radiation proof lead plate structure, including a lead plate body, one end of the lead plate body has a male buckle, and the other end has a female buckle that can be plugged and matched with the male buckle in other lead plate structures, the male buckle includes a first folded edge parallel to the lead plate body, and the free end of the first folded edge extends from away from the center of the lead plate toward the center of the lead plate; the female buckle includes a stopper and a bending portion, the stopper is arranged on a side of the bending portion close to the center of the lead plate body, the bending portion includes a parallel section parallel to the lead plate body, the gap between the parallel section and the lead plate body forms an opening facing the center of the lead plate body, and the side of the bending portion away from the center of the lead plate body is connected to an extension plate; the extension plate is used to connect to the wall through bolts.

[0007] The stopper can be bent to be in a vertical state and a fitted state. In the vertical state, the stopper is perpendicular to the lead plate body, and the distance between the stopper and the parallel section is equal to the length of the first folded edge. In the fitted state, the stopper is parallel to the extension direction of the lead plate body and the two are fitted together, and the free end of the stopper stops at the opening of the bent portion to limit the first folded edge from detaching from the opening.

[0008] The beneficial effects of one or more of the above technical solutions are:

[0009] In this solution, two adjacent lead plates can be clamped and fixed through a male buckle and a female buckle. Therefore, it is not necessary to use bolts to fix two adjacent lead plates, and there are no screw holes that penetrate through two lead plates at the same time, effectively avoiding the weakening of the radiation protection performance of the lead plates by the screw holes.

[0010] In this solution, an extension plate is provided on the side of the female buckle away from the stop portion. The extension plate is connected to the wall through bolts. In the clamping state of the male buckle and the female buckle of adjacent lead plates in this solution, the screw holes and bolts on the extension plate can be covered, thereby avoiding the influence of the screw holes and bolts at the extension plate on the radiation protection performance of the lead plates.

[0021] The stopper 3 can be bent to be in a vertical state and a fitted state. In the vertical state, the stopper 3 is perpendicular to the lead plate body 2, and the distance between the stopper 3 and the parallel section is equal to the length of the first folded edge 101. In the fitted state, the stopper 3 is parallel to the extension direction of the lead plate body 2 and the two are fitted together. The free end of the stopper 3 stops at the opening 406 of the bending portion to limit the first folded edge 101 from detaching from the opening 406.

[0022] Specifically, the lead plate structure in this solution is in a square shape, and the thickness of the lead plate body 2 is 0.5mm-20mm. The lead plate body 2 has two side surfaces perpendicular to its thickness direction, and the male buckle 1 and the female buckle 4 protrude from the side surfaces of the lead plate body 2.

[0023] In this embodiment, the stopper portion 3 and the bending portion are a double-layer structure formed by bending the lead plate body 2, and the stopper portion 3 includes a second folded edge 301 and a third folded edge 302 connected in sequence, and the second folded edge 301 and the third folded edge 302 are in contact with each other.

[0024] Specifically, the male buckle 1 and the female buckle 4 are integrally formed with the lead plate body 2, and the male buckle 1 and the female buckle 4 are formed by bending the two ends of the lead plate body. This arrangement can reduce the difficulty of manufacturing the entire lead plate structure.

[0025] In this embodiment, the bending portion includes a fourth fold 404, a fifth fold 401 and a sixth fold 402 connected in sequence, and the fourth fold 404 and the fifth fold 401 are attached to each other to form a parallel section. The sixth fold 402 is curved to achieve the transition between the fifth fold 401 and the extension plate 403.

[0026] Specifically, there are arc transitions formed by bending between the second folded edge 301, the third folded edge 302 and the lead plate body 2. There are also arc transitions formed by bending between the fourth folded edge 404 and the lead plate body 2, and between the fourth folded edge 404 and the fifth folded edge 401.

[0027] In this embodiment, at least one screw hole is preset on the extension plate 403, and a screw for connecting to the wall body is provided in the screw hole. Preferably, a row of screw holes is provided along the side direction of the lead plate structure on the extension plate 403. At this time, the lead plate structure is fixedly connected to the external wall body through a row of screw holes and screws at the extension plate 403.

[0028] Specifically, the screw hole here can be a through hole preset on the extension plate 403. In some other embodiments, the screw hole here can be formed by drilling the extension plate 403 with a screw.

[0029] In this embodiment, the male buckle 1 further includes a seventh folded edge 102 and an eighth folded edge 103. The eighth folded edge 103, the seventh folded edge 102, and the first folded edge 101 are connected in sequence. The seventh folded edge 102 is parallel to the first folded edge 101, and the eighth folded edge 103 is curved to realize the transition between the seventh folded edge 102 and the lead plate body 2.

[0030] Specifically, the above-mentioned first folded edge 101, second folded edge 301, third folded edge 302, fourth folded edge 404, fifth folded edge 401, and seventh folded edge 102 are all flat plate structures.

[0031] In this embodiment, a stiffening rib is formed by bending in the middle of the lead plate body 2. Specifically, the cross-section of the stiffening rib here can be U-shaped or arched, and can be set by those skilled in the art themselves.

[0032] In this embodiment, a filling plate 405 is provided between the parallel section and the lead plate body 2. Specifically, the filling plate 405 includes a rigid plate and a flexible plate that are mutually attached. One end of the filling plate 405 facing the center of the lead plate body 2 has a bevel chamfer. More specifically, the rigid plate here can be a metal plate or a plastic plate, and the flexible plate can be a rubber plate or a silica gel plate. When in use, the flexible plate is on the side of the rigid plate facing the parallel section. Preferably, the rigid plate and the flexible plate are bonded and fixed by an adhesive, and the rigid plate and the lead plate body 2 are also fixed by an adhesive.

[0033] Working principle: As Figures 3-5 shown, the ends of two lead plate structures (i.e., the first lead plate 201 and the second lead plate 202 shown in the figure) are mutually clamped through the male buckle 1 and the female buckle 4.

[0034] First, position the first lead plate 201 where the female buckle 4 is located with the wall surface, and then use screws to fix the extension plate 403 on the first lead plate 201 to the wall surface. Place the male buckle 1 of the second lead plate 202 at the position of the female buckle 4 of the first lead plate 201, and insert the first folded edge 101 of the second lead plate 202 into the opening 406 formed between the parallel section and the lead plate body 2 of the first lead plate 201, so that the free end of the first folded edge 101 abuts against the connection between the parallel section and the lead plate body 2 to ensure the insertion depth of the first folded edge 101.

[0035] Then bend the stopper portion 3 towards the opening 406 so that the stopper portion 3 fits against the lead plate body 2, and the free end of the stopper portion 3 abuts against the first folded edge 101 of the male buckle 1 to prevent the first folded edge 101 from disengaging from the opening 406.

[0036] The above specific embodiments cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art of this technology, any alternative improvement or transformation made to the embodiments of the present utility model falls within the protection scope of the present utility model.
