Description

Technical Field

[0001] This utility model relates to the field of protective lead door technology, specifically a large protective lead door assembled from lead bricks. Background Technology

[0002] In protective lead doors, lead bricks are widely used as a key protective material in various locations requiring radiation protection, such as medical, scientific research, and nuclear industries. Traditional lead door designs typically embed lead bricks within the door structure to provide the necessary radiation shielding. However, the current assembly methods for lead bricks present some problems.

[0003] Specifically, most lead bricks are currently designed to be square. While this design facilitates manufacturing and assembly, it easily leads to gaps in actual use. Due to differences in size and installation precision among the lead bricks, it is often difficult to achieve a completely tight seal between square lead bricks. These gaps not only reduce the overall protective effect of the lead door but also easily become potential sources of radiation leakage. Utility Model Content

[0004] (I) Purpose of the utility model

[0005] In view of this, the purpose of this utility model is to propose a large protective lead door assembled from lead bricks, which solves the problems mentioned in the background above.

[0006] (II) Technical Solution

[0007] A large protective lead door assembled from lead bricks is characterized by comprising multiple sets of outer panels, frames, and keel frames. Each set of the keel frames is provided with locking blocks, and the locking blocks are L-shaped. The inner wall of the keel frames is provided with multiple sets of second lead blocks and multiple sets of first lead blocks, and the multiple sets of second lead blocks and multiple sets of first lead blocks are all convex. The multiple sets of second lead blocks, first lead blocks, and locking blocks are assembled by overlapping each other, so that the gaps form shielding surfaces between them.

[0008] Preferably, multiple sets of limiting rods are fixedly installed on the inner wall of the keel frame, and a limiting groove is formed on one side of the outer surface of the multiple sets of limiting rods. A connecting rod is connected to the inner wall of the limiting groove, and one end of the connecting rod is connected to the first lead block and the second lead block respectively.

[0009] Preferably, steel plates are fixedly installed on both sides of the keel frame.

[0010] Preferably, multiple sets of reinforcing clips are fixedly installed at the outer end of the keel frame, and the multiple sets of reinforcing clips are welded together. The keel frame is fixedly installed in the inner wall of the frame, and outer plates are fixedly installed on both sides of the frame.

[0011] Preferably, the connecting rod is rectangular with an arc-shaped outer end.

[0012] Preferably, the outer surface of the connecting rod is covered with rubber.

[0013] Preferably, the connecting ends of the multiple sets of reinforced housings are triangular.

[0014] As can be seen from the above technical solutions, this application has the following beneficial effects:

[0015] 1. This utility model cleverly incorporates a first and second lead block, designed in a convex shape, and an L-shaped locking block within the keel frame. This unique design offers significant advantages. First, the convex shape increases the contact area between the lead blocks, allowing for a tighter overlap and assembly, forming a compact arrangement. This not only improves assembly efficiency but also effectively utilizes space, minimizing gaps. More importantly, this design creates an additional shielding surface, effectively blocking radiation that might leak through gaps, thereby enhancing the protective performance of the lead door.

[0016] 2. The key to ensuring the accurate positioning of the first and second lead blocks during installation lies in the tight fit between the connecting rod and the limiting groove. The connecting rod is rectangular in design, with one end connected to the lead block and the other end precisely embedded in the limiting groove. This design not only enhances the stability of the lead blocks but also ensures that the lead blocks are not easily displaced or deformed after installation. Attached Figure Description

[0023] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] A large protective lead door assembled from lead bricks is characterized by comprising multiple sets of outer panels 1, frames 2, and keel frames 5. Each set of keel frames 5 is provided with a locking block 7, and the locking block 7 is L-shaped. The inner wall of the keel frame 5 is provided with multiple sets of second lead blocks 8 and multiple sets of first lead blocks 6, and the multiple sets of second lead blocks 8 and multiple sets of first lead blocks 6 are all convex. The multiple sets of second lead blocks 8, first lead blocks 6, and locking blocks 7 are assembled by overlapping each other, so that the gaps form shielding surfaces between them.

[0026] Furthermore, multiple sets of limiting rods 911 are fixedly installed on the inner wall of the keel frame 5, and a limiting groove 912 is opened on one side of the outer surface of the multiple sets of limiting rods 911. A connecting rod 9 is connected to the inner wall of the limiting groove 912. One end of the connecting rod 9 is connected to the first lead block 6 and the second lead block 8 respectively. The multiple sets of limiting rods 911 enhance the tightness and stability of the lead block arrangement, effectively preventing the lead blocks from being misaligned or loosened during use, thereby ensuring the overall protective performance of the lead door.

[0027] Furthermore, steel plates 3 are fixedly installed on both sides of the keel frame 5. The steel plates 3 not only provide additional strength and support for the lead door, but also enhance the lead door's impact resistance. When it needs to withstand large external forces or impacts, the steel plates can absorb and disperse these forces, protecting the internal lead block structure from damage.

[0028] Furthermore, multiple sets of reinforcing clips 4 are fixedly installed at the outer end of the keel frame 5, and these reinforcing clips 4 are welded together. The keel frame 5 is fixedly installed in the inner wall of the frame 2, and outer plates 1 are fixedly installed on both sides of the frame 2. The welded connection of the reinforcing clips 4 not only enhances the structural stability but also improves the protective performance of the lead door. It can effectively block and disperse external impacts or pressures, protecting the internal lead block structure from damage, thereby ensuring that the lead door can continuously provide a high level of radiation protection.

[0029] Furthermore, the connecting rod 9 is rectangular with an arc-shaped outer end, ensuring a tight fit with the limiting groove 912, while the arc-shaped outer end design reduces friction and wear.

[0030] Furthermore, the outer surface of the connecting rod 9 is wrapped with rubber, which improves the sealing and stability of the connection.

[0031] Furthermore, the connecting ends of the multiple sets of reinforcing clips 4 are triangular. The triangular connecting end design increases the contact area and connection strength between the reinforcing clips 4. When multiple reinforcing clips 4 are connected together by welding or other methods, the triangular connecting ends can provide a more solid connection point, reducing the risk of structural failure due to weak or loose connections.

[0032] Working principle: First, the first lead block 6 and the second lead block 8, designed in a convex shape, along with the L-shaped interlocking block 7, are cleverly placed inside the keel frame 5. This special design allows the lead blocks to overlap and assemble, forming a tight arrangement. During assembly, the convex design not only increases the contact area between the lead blocks but also effectively utilizes space, minimizing gaps. Simultaneously, it forms an additional shielding surface, blocking radiation that might leak through gaps.

[0033] Next, the tight fit between the connecting rod 9 and the limiting groove 912 ensures the accurate positioning of the first lead block 6 and the second lead block 8 during installation. The connecting rod 9 has a rectangular design, with one end connected to the lead block and the other end embedded in the limiting groove 912. This design not only enhances the stability of the lead block but also effectively prevents it from shifting or deforming during long-term use. In addition, the rounded outer end of the connecting rod 9 and the rubber layer covering its outer surface improve the tightness and durability of the connection.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
