Description

Technical Field

[0001] This utility model relates to the field of safety protection door technology, and in particular to a special safety protection door that is explosion-proof and impact-resistant. Background Technology

[0002] Explosion-proof impact-resistant special safety doors are widely used in chemical, mining, and military industries where there is a risk of explosion. Their sealing performance is directly related to the safety of protection after an explosion. They not only need to block the shock wave from damaging the door body, but also prevent toxic and harmful gases, flammable and explosive dust and high-temperature fumes generated by the explosion from seeping into non-dangerous areas through the joints between the door body and the door frame, so as to avoid secondary disasters.

[0003] Currently, most mainstream sealing structures use sealing strips made of a single material. Although ordinary rubber strips have basic elasticity, they are prone to permanent deformation or tearing under strong impact. They are also not resistant to high and low temperatures or chemical corrosion. In addition, explosive impacts often cause slight deformation of the door or door frame, which increases the width of the joint. Existing sealing structures lack the ability to actively adapt to deformation, making them prone to sealing failure. Moreover, it is difficult to detect the failure quickly, which poses a hidden danger to subsequent safety protection.

[0004] Therefore, it is necessary to invent a special safety door that is explosion-proof and impact-resistant to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a special safety door that is explosion-proof and impact-resistant, in order to solve the problems mentioned in the background art. Currently, the mainstream sealing structure mostly uses a single material sealing strip. Although ordinary rubber strips have basic elasticity, they are prone to permanent deformation or tearing under strong impact. Moreover, they are not resistant to high and low temperatures or chemical corrosion. In addition, explosion impacts often cause slight deformation of the door body or door frame, which increases the width of the joint. Existing sealing structures lack the ability to actively adapt to deformation, making them prone to sealing failure. Furthermore, it is difficult to detect the failure quickly, which poses a hidden danger to subsequent safety protection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a special safety door for explosion-proof impact protection, comprising a door frame and a door body, wherein a hinge is provided between the door frame and the door body, a bottom plate is fixedly connected to the bottom end of the door frame, and plug-in plates are provided on the inner sides of both the upper and lower ends of the door body, and a fixing plate is fixedly connected to the top end of the plug-in plates, wherein the plug-in plates and the fixing plates are slidably connected to the inner side of the door body;

[0007] The inner side of the plug plate is provided with expanding rubber, and the inner side of the fixing plate is provided with butyl rubber sealing strip and graphite sealing strip, with the butyl rubber sealing strip located at the top of the graphite sealing strip.

[0008] As a preferred embodiment, a protective film is provided on the inner side of the fixing plate, and the protective film is located at the top of the inner side of the fixing plate and at the top of the butyl rubber sealing strip.

[0010] As a preferred embodiment, the mounting block has a hidden groove and a through hole on its inner side, and a fastening bolt is provided on the outer side of the hidden groove. The mounting block is fixedly connected to the inner side of the protective door body by the fastening bolt.

[0011] As a preferred embodiment, the inner edge of the door frame is provided with a groove, and the opening of the groove is set to correspond to the opening of the fixing plate.

[0012] As a preferred embodiment, two protective door bodies are symmetrically arranged, and multiple plug-in rods are evenly arranged on one side of the protective door body. A rotating handle is provided on the outer side of the protective door body, and the rotating handle is connected to the plug-in rods through mutual transmission.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model, by setting up a plug-in plate, butyl rubber sealing strip, graphite sealing strip, and expanding rubber, allows the expanding rubber to expand when the protective door body is impacted and reaches a certain pressure. This causes the butyl rubber sealing strip and graphite sealing strip to be squeezed out from the top of the fixing plate and placed inside the groove.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see the appendix Figure 1 - Appendix Figure 5 A special safety door for explosion-proof impact protection includes a door frame 1 and a door body 2. A hinge 12 is provided between the door frame 1 and the door body 2. A base plate 11 is fixedly connected to the bottom end of the door frame 1. Insertion plates 3 are provided on the inner sides of both the upper and lower ends of the door body 2. A fixing plate 31 is fixedly connected to the top of the insertion plate 3. The insertion plate 3 and the fixing plate 31 are slidably connected to the inner side of the door body 2.

[0027] An expansion rubber 36 is provided on the inner side of the plug plate 3, and a butyl rubber sealing strip 34 and a graphite sealing strip 35 are provided on the inner side of the fixing plate 31. The butyl rubber sealing strip 34 is located at the top of the graphite sealing strip 35.

[0028] Specifically, by setting up a plug-in plate 3, which contains a butyl rubber sealing strip 34, a graphite sealing strip 35, and an expanding rubber 36, the plug-in plate 3 is located inside the protective door body 2. When the protective door body 2 is impacted and reaches a certain pressure, the expanding rubber 36 expands, causing the butyl rubber sealing strip 34 and the graphite sealing strip 35 to be squeezed out from the top of the fixing plate 31. This allows the butyl rubber sealing strip 34 and the graphite sealing strip 35 to be positioned inside the groove 13, effectively sealing the door frame 1 and the protective door body 2. This effectively improves the sealing effect between the door frame 1 and the protective door body 2, effectively preventing smoke or toxic gases from entering through the gap between the door frame 1 and the protective door body 2, thus improving safety. The expanding rubber 36 is filled with expanding rubber. When the protective door body 2 is impacted, and the pressure generated by the shock wave is ≥0.1MPa, the expanding rubber 36 will directly expand, effectively squeezing out the butyl rubber sealing strip 34 and the graphite sealing strip 35 from the top of the fixing plate 31. The butyl rubber sealing strip 34 can quickly fill between the door frame 1 and the protective door body 2. At the same time, the graphite sealing strip 35 has the advantages of high temperature resistance and chemical corrosion resistance. As a secondary sealing barrier, it blocks the penetration of high temperature flue gas and corrosive media. The flexible characteristics of graphite material can complement the butyl rubber sealing strip 34. Basic sealing is achieved before the butyl rubber sealing strip 34 is completely filled between the door frame 1 and the protective door body 2. After expansion, the sealing strength is enhanced. The metal wire reinforcement structure improves the tear resistance of the graphite strip and prevents it from wearing and breaking during the opening and closing of the door.

[0029] Please see the appendix Figure 5 A protective film 33 is provided on the inner side of the fixing plate 31. The protective film 33 is located at the top of the inner side of the fixing plate 31 and at the top of the butyl rubber sealing strip 34.

[0030] Specifically, by providing a protective film 33 on the inner side of the fixing plate 31, with the protective film 33 positioned at the top of the inner side of the fixing plate 31 and at the top of the butyl rubber sealing strip 34, the protective film 33 can effectively seal the opening at the top of the fixing plate 31, preventing water or dust and other debris from entering the inner side of the fixing plate 31 and the plug plate 3, effectively preventing the butyl rubber sealing strip 34 and the graphite sealing strip 35 from being contaminated, and effectively extending the storage time of the butyl rubber sealing strip 34 and the graphite sealing strip 35.

[0031] Please see the appendix Figure 4 The bottom end of the plug plate 3 is fixedly connected to the mounting block 32. The protective door body 2 is provided with a groove corresponding to the mounting block 32. The mounting block 32 is located inside the groove. The inner side of the mounting block 32 is provided with a hidden groove 321 and a through hole 322. The outer side of the hidden groove 321 is provided with a fastening bolt 323. The mounting block 32 is fixedly connected to the inner side of the protective door body 2 by the fastening bolt 323.

[0032] Specifically, an mounting block 32 is fixedly connected to the bottom end of the plug-in plate 3. The protective door body 2 has a corresponding groove for the mounting block 32. The mounting block 32 is located inside the groove. After the plug-in plate 3 and the fixing plate 31 are slid from the side of the protective door body 2 to the inside, the mounting block 32 also slides into the groove on the side of the protective door body 2 for engagement. A hidden groove 321 and a through hole 322 are provided inside the mounting block 32. A fastening bolt 323 is provided on the outer side of 1. The mounting block 32 is fixedly connected to the inner side of the protective door body 2 by the fastening bolt 323. The hidden groove 321 can effectively hide the fastening bolt 323. By providing a through hole 322, a hole is also opened at the corresponding position of the protective door body 2. The fastening bolt 323 can be passed through the through hole 322 and threaded to the inner side of the protective door body 2, thereby effectively fixing the mounting block 32 to the inner side of the protective door body 2.

[0033] Please see the appendix Figure 2 and Figure 4 The inner edge of the door frame 1 is provided with a groove 13, and the opening of the groove 13 is set to correspond to the opening of the fixing plate 31.

[0034] Specifically, by providing grooves 13 on the inner edge of the door frame 1, with the openings of the grooves 13 corresponding to the openings of the fixing plate 31, when the protective door body 2 is impacted, the butyl rubber sealing strip 34 and the graphite sealing strip 35 will expand out from the opening at the top of the fixing plate 31, allowing the butyl rubber sealing strip 34 and the graphite sealing strip 35 to enter the inner side of the grooves 13, fully filling the space between the door frame 1 and the protective door body 2, effectively improving the sealing performance between the door frame 1 and the protective door body 2.

[0035] Please see the appendix Figure 3 There are two protective door bodies 2 symmetrically arranged, and multiple plug-in rods 21 are evenly arranged on one side of the protective door body 2. A rotating handle 22 is provided on the outer side of the protective door body 2. The rotating handle 22 and the plug-in rods 21 are connected to each other through transmission.

[0036] Specifically, multiple insertion rods 21 are evenly arranged on the side of the protective door body 2, and a rotating handle 22 is provided on the outer side of the protective door body 2. The rotating handle 22 is connected to the insertion rods 21 through mutual transmission. Rotating the rotating handle 22 can effectively drive the insertion rods 21 to move. The other side of the protective door body 2 has a groove corresponding to the insertion rod 21. Thus, after the two protective door bodies 2 are closed, the insertion rods 21 can be moved to the inner side of the other protective door body 2 by rotating the rotating handle 22 for insertion, so that the two protective door bodies 2 can be completely sealed and closed, effectively improving the safety of use.

[0037] The working principle of this utility model is as follows: In specific use, the two protective door bodies 2 are closed. Multiple plug-in rods 21 are evenly arranged on the side of the protective door body 2. A rotating handle 22 is provided on the outer side of the protective door body 2. The rotating handle 22 is connected to the plug-in rods 21 through mutual transmission. Rotating the rotating handle 22 can effectively drive the plug-in rods 21 to move. The other side of the protective door body 2 has a groove corresponding to the plug-in rods 21. Thus, after the two protective door bodies 2 are closed, the plug-in rods 21 can be moved to the inner side of the other protective door body 2 by rotating the rotating handle 22 for plugging. This allows the two protective door bodies 2 to be completely sealed and closed, effectively improving the safety of use.

[0038] When the protective door body 2 is impacted, and the pressure generated by the shock wave is ≥0.1MPa, the expanding rubber 36 will expand directly, effectively squeezing out the butyl rubber sealing strip 34 and the graphite sealing strip 35 from the top of the fixing plate 31. The butyl rubber sealing strip 34 can quickly fill between the door frame 1 and the protective door body 2. At the same time, the graphite sealing strip 35 has the advantages of high temperature resistance and chemical corrosion resistance. As a secondary sealing barrier, it blocks the penetration of high temperature flue gas and corrosive media. The flexible characteristics of graphite material can complement the butyl rubber sealing strip 34. Basic sealing is achieved before the butyl rubber sealing strip 34 is completely filled between the door frame 1 and the protective door body 2. After expansion, the sealing strength is enhanced. The metal wire reinforcement structure improves the tear resistance of the graphite strip and prevents it from wearing and breaking during the opening and closing of the door.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
