Description

Technical Field

[0001] The present invention relates to the technical field of explosion-proof isolation doors, and particularly to an explosion-proof isolation door for a business library. Background Art

[0002] The explosion-proof isolation door for a business library is a high-security protection facility designed specifically for high-risk places such as financial institutions and storage of valuables. It is mainly used to isolate external intrusion threats and ensure the safety inside the warehouse.

[0003] Existing explosion-proof isolation door technologies, such as a banking business library with a prevention and control isolation door disclosed in the publication number CN114607233A, can close the prevention and control isolation door to shield the explosion-proof box body by moving the push plate forward through an electric push rod. Closing the prevention and control isolation door to shield the explosion-proof box body can prevent the password of the vault door from being peeked, monitored, or secretly photographed, improving the protection effect. And the prevention and control isolation door shielding the explosion-proof box body can further protect cash and valuables. However, the following problems exist in use:

[0004] By moving the push plate forward, the prevention and control isolation door is closed to shield the explosion-proof box body, improving the protection effect. However, the door frame cannot be reinforced. When the door frame encounters a strong impact, the door body will transmit the impact force to the door frame. When the firmness of the door frame is insufficient, it is easy to cause damage to the door frame and even cause the explosion-proof door to fall off the door frame, unable to effectively protect the items in the business library. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that the door frame cannot be reinforced, and to propose an explosion-proof isolation door for a business library.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An explosion-proof isolation door for a business library includes a wall body and an explosion-proof door frame disposed inside the wall body. A plurality of first reinforcing ribs and second reinforcing ribs for fixing the explosion-proof door frame are embedded in the wall body. A first cavity is formed inside the explosion-proof door frame. A plurality of first fixing seats and second fixing seats for respectively fixing the first reinforcing ribs and the second reinforcing ribs to the inside of the explosion-proof door frame are disposed inside the first cavity. An explosion-proof door is disposed inside the explosion-proof door frame. A second cavity is formed inside the explosion-proof door. A reinforcing rod for resisting impact is disposed inside the second cavity. Steel protection plates for reinforcing the explosion-proof door are fixedly installed on the outer walls on both sides of the explosion-proof door.

[0008] Preferably, four equally spaced fixing blocks are fixedly installed in the first cavity. First fixing plates and second fixing plates fixedly installed in the first cavity are respectively arranged on the outer walls of both sides of the first fixing seat and the second fixing seat. A connecting rib penetrating through the first fixing plate and the second fixing plate is arranged between the first fixing plate and the second fixing plate, and both ends of the connecting rib are respectively embedded in two parallel fixing blocks.

[0009] Preferably, four equally spaced through holes are respectively formed in the first fixing plate and the second fixing plate. Fixing columns for preventing the first fixing seat and the second fixing seat from moving are fixedly installed in the through holes formed in the first fixing plate and the second fixing plate. Both ends of the fixing columns are fixedly installed in the first cavity, and the connecting rib is arranged between the two fixing columns.

[0010] Preferably, two symmetrically arranged fixing sleeves are fixedly installed on the outer wall of the explosion-proof door frame. A rotating rod is rotatably installed on the fixing sleeve through a rotating shaft, and the rotating rod is fixedly connected to the explosion-proof door.

[0011] Preferably, multiple groups of equally spaced cross bars are fixedly installed in the second cavity. Each group consists of two cross bars. A vertical bar is fixedly installed between the two cross bars. Multiple symmetrically arranged reinforcing bars are fixedly installed in the second cavity. One end of the reinforcing bar is fixedly installed on the outer wall of the vertical bar to ensure the stability of the vertical bar.

[0012] Preferably, two symmetrically arranged fixing rods fixedly installed in the second cavity and respectively embedded in a plurality of vertically distributed vertical bars are provided. First thread grooves and second thread grooves are formed on the outer wall of the fixing rod, and both the first thread groove and the second thread groove are arranged on both sides of the vertical bar.

[0013] Preferably, fixing nuts are respectively sleeved on the outer walls of the first thread groove and the second thread groove through threads. Gaskets are respectively arranged between the fixing nuts and the outer wall of the vertical bar. The first thread groove and the second thread groove are provided with reverse threads.

[0014] Preferably, multiple groups of fixing piles are fixedly installed in the second cavity. Each group of fixing piles consists of five fixing piles arranged in a plum blossom shape. A fixing piece is sleeved on the outer wall of the fixing pile. A bolt body embedded in the vertical bar and penetrating through the two fixing pieces is arranged between the fixing pieces. Nuts are respectively sleeved on the outer walls of the bolt bodies.

[0015] Preferably, the nuts are arranged on the outer walls of both sides of the two fixing pieces, and the nuts are cross-arranged on the front and back sides of the vertical bar.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. By deeply embedding the first reinforcing rib and the second reinforcing rib into the wall body, the present invention ensures the overall firmness between the explosion-proof door frame and the wall body.

Detailed implementation manner

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] Refer to Figures 1 - 9 , an explosion-proof isolation door for a business library, including a wall body 1 and an explosion-proof door frame 2 arranged in the wall body 1. A plurality of first reinforcing ribs 6 and second reinforcing ribs 8 for fixing the explosion-proof door frame 2 are embedded in the wall body 1. By embedding the first reinforcing ribs 6 in the wall body 1, the second reinforcing ribs 8 are embedded between two first reinforcing ribs 6, which is convenient for enhancing the firmness between the explosion-proof door frame 2 and the wall body 1, and effectively ensuring the stability of the explosion-proof door frame 2. A first cavity 3 is opened in the explosion-proof door frame 2, and a plurality of first fixing seats 5 and second fixing seats 7 for respectively fixing the first reinforcing ribs 6 and the second reinforcing ribs 8 to the inside of the explosion-proof door frame 2 are arranged in the first cavity 3. An explosion-proof door 13 is arranged in the explosion-proof door frame 2. A second cavity 14 is opened in the explosion-proof door 13, and a reinforcing bar 17 for resisting impact is arranged in the second cavity 14. Steel guard plates 27 for strengthening the explosion-proof door 13 are fixedly installed on the outer walls on both sides of the explosion-proof door 13.

[0032] Four equally spaced fixing blocks 4 are fixedly installed in the first cavity 3. First fixing plates 9 and second fixing plates 10 fixedly installed in the first cavity 3 are respectively arranged on the outer walls on both sides of the first fixing seat 5 and the second fixing seat 7. A connecting rib 11 penetrating through the first fixing plate 9 and the second fixing plate 10 is arranged between the first fixing plate 9 and the second fixing plate 10. The two ends of the connecting rib 11 are respectively embedded in two parallel fixing blocks 4, which is convenient for limiting, fixing and stretching the connecting rib 11. The first fixing seat 5 and the second fixing seat 7 are fixed by the first fixing plate 9 and the second fixing plate 10, preventing the first reinforcing rib 6 and the second reinforcing rib 8 from sliding out of the first cavity 3. The first fixing plate 9 and the second fixing plate 10 are fixed by four fixing columns 12, further improving the fixing firmness of the first fixing plate 9 and the second fixing plate 10 to the first fixing seat 5 and the second fixing seat 7. The first fixing plate 9 and the second fixing plate 10 are connected by the connecting rib 11, increasing the overall stability between the first fixing plate 9 and the second fixing plate 10.

[0033] Four equally spaced through holes are provided in both the first fixing plate 9 and the second fixing plate 10. Fixing columns 12 for preventing the first fixing seat 5 and the second fixing seat 7 from moving are fixedly installed in the through holes provided in the first fixing plate 9 and the second fixing plate 10. The first fixing plate 9 and the second fixing plate 10 and the first fixing seat 5 and the second fixing seat 7 are fixed as a whole by four rectangular fixing columns 12, preventing relative displacement of the first fixing seat 5 and the second fixing seat 7 and ensuring the stability of the first fixing seat 5 and the second fixing seat 7. Both ends of the fixing column 12 are fixedly installed in the first cavity 3. By injecting concrete into the first cavity 3, the firmness of the first fixing seat 5 and the second fixing seat 7 is further improved. The connecting rib 11 is arranged between two fixing columns 12.

[0034] Two symmetrically arranged fixing sleeves 28 are fixedly installed on the outer wall of the explosion-proof door frame 2. A rotating rod 29 is rotatably installed on the fixing sleeve 28 through a rotating shaft. The rotating rod 29 is fixedly connected to the explosion-proof door 13, facilitating the opening and closing of the explosion-proof door 13.

[0035] Multiple groups of equally spaced cross bars 15 are fixedly installed in the second cavity 14. Each group consists of two cross bars 15. A vertical bar 16 is fixedly installed between the two cross bars 15. Multiple symmetrically arranged reinforcing bars 17 are fixedly installed in the second cavity 14. One end of the reinforcing bar 17 is fixedly installed on the outer wall of the vertical bar 16 and used to ensure the stability of the vertical bar 16. When the explosion-proof door 13 is impacted by an external force, the external force is transmitted to the vertical bar 16 through the reinforcing bar 17. The vertical bars 16 are connected by the fixing bar 18 and the fixing piece 24, increasing the overall stability between the vertical bars 16 and facilitating the improvement of the impact resistance of the vertical bars 16.

[0036] Two fixing rods 18 are fixedly installed symmetrically in the second cavity 14 and are both embedded in a plurality of vertically distributed vertical rods 16. Thread grooves 19 and 20 are formed on the outer wall of the fixing rod 18, and both the first thread groove 19 and the second thread groove 20 are arranged on both sides of the vertical rod 16. By injecting concrete into the second cavity 14, the safety and firmness of the explosion-proof door 13 are further ensured.

[0037] Fixing nuts 21 are sleeved on the outer walls of both the first thread groove 19 and the second thread groove 20 through threads, and gaskets 22 are arranged between the fixing nuts 21 and the outer walls of the vertical rods 16. The first thread groove 19 and the second thread groove 20 are arranged with reverse threads. Through the first thread groove 19 and the second thread groove 20 arranged with reverse threads, the fixing nuts 21 on both sides of the vertical rod 16 move towards each other, so that the two fixing nuts 21 arranged on the left and right sides of the vertical rod 16 simultaneously push the two gaskets 22 to move, and the two gaskets 22 fix the vertical rod 16, avoiding the vertical rod 16 from shifting and affecting the stability inside the explosion-proof door 13.

[0038] Multiple groups of fixing piles 23 are fixedly installed in the second cavity 14, and each group of fixing piles 23 is composed of five fixing piles 23 arranged in a plum blossom shape, which is convenient for the reasonable distribution of the spacing between the piles, can effectively disperse the load of the upper structure, avoid local stress concentration, and the staggered arrangement between the piles can enhance the overall lateral displacement resistance ability, avoiding the vertical rod 16 from being impacted and shifting. A fixing piece 24 is sleeved on the outer wall of the fixing pile 23, and a bolt body 25 that is embedded in the vertical rod 16 and penetrates through the two fixing pieces 24 is arranged between the fixing pieces 24. Nuts 26 are sleeved on the outer walls of the bolt bodies 25.

[0039] The nuts 26 are arranged on the outer walls of both sides of the two fixing pieces 24, and the nuts 26 are arranged in a cross shape on the front and rear sides of the vertical rod 16. The cross arrangement of the nuts 26 can reduce the possibility of all the nuts 26 loosening at the same time. If one side of the nuts 26 loosens due to vibration or other reasons, the nuts 26 on the other side can still maintain a tightened state, thereby reducing the risk of loosening between the two fixing pieces 24 and making the fixation of the vertical rod 16 more firm.

[0040] The functional principle of the present invention can be elaborated through the following operation methods:

[0041] During use, by embedding the first reinforcing rib 6 and the second reinforcing rib 8 into the wall body 1, the stability and firmness of the explosion-proof door frame 2 are ensured. By injecting concrete into the first cavity 3, the stability of each component inside the explosion-proof door frame 2 and the strength of the explosion-proof door frame 2 are ensured. The first fixing plate 9 and the second fixing plate 10 are fixed in the first cavity 3 through the fixing column 12, so that the first fixing plate 9 and the second fixing plate 10 respectively fix the first fixing seat 5 and the second fixing seat 7, avoiding the first reinforcing rib 6 and the second reinforcing rib 8 from separating from the explosion-proof door frame 2;

[0042] By respectively turning the fixing nuts 21 on the first threaded groove 19 and the second threaded groove 20, the two fixing nuts 21 respectively push the two gaskets 22 to move towards each other, so that the two gaskets 22 fix the vertical rod 16, ensuring the overall stability of the vertical rod 16. The nuts 26 are arranged in a cross pattern on the front and back sides of the vertical rod 16, so that the bolt body 25 fixes the two fixing pieces 24 on both sides of the vertical rod 16, ensuring the stability of the middle part of the vertical rod 16. The force received by the explosion-proof door frame 2 is transmitted to the vertical rod 16 through the reinforcing rod 17, improving the anti-striking ability of the explosion-proof door 13.

[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered within the protection scope of the present invention.
