Description

Technical Field

[0001] This utility model relates to the technical field of protective doors, specifically to an alloy impact-resistant protective door. Background Art

[0002] Fire doors are doors that can meet the requirements of fire resistance stability, integrity, and heat insulation within a certain period of time. They are fire-resistant partitions with a certain degree of fire resistance, installed in fire compartments, evacuation stairwells, vertical shafts, etc. The door frame, door leaf skeleton, and door leaf panel are made of steel materials. If the door leaf is filled with material, it is filled with fire-resistant and heat-insulating material that is non-toxic and harmless to the human body.

[0003] After a fire breaks out, the air pressure in the tunnel increases, which may cause high-pressure impact on the fire doors. Mine fire doors in related technologies usually consist of a door frame and a door leaf. Their structure is relatively simple and their impact resistance is poor. Fire doors are easily damaged under high-pressure impact. Summary of the Invention

[0004] The purpose of this invention is to provide an alloy impact-resistant protective door to solve the above-mentioned defects caused by the prior art.

[0005] An impact-resistant alloy protective door includes an alloy door body, a door handle connected to one side of the alloy door body, multiple sets of hinges evenly spaced on one side of the alloy door body, a protective mechanism inside the alloy door body that supports and protects the interior of the alloy door body, improving the impact resistance of the alloy door body, and a positioning mechanism at the top of the interior of the alloy door body that vertically positions the alloy door body, thereby preventing the alloy door body from failing to close properly in the event of a fire, resulting in smoke overflow, or preventing the alloy door body from tipping over due to damage to the hinges on one side of the alloy door body in a fire.

[0006] Preferably, the protection mechanism includes a handle, an explosion-proof plate, a guide rod, and a polyurethane foam board. A gear is provided on one side of the handle, and an alloy door is connected through one side of the handle. A polyurethane foam board is provided inside the alloy door, an explosion-proof plate is provided on the other side of the polyurethane foam board, and a guide rod is provided directly above the polyurethane foam board.

[0007] Preferably, a guide rod is provided directly above the polyurethane foam board and is internally connected to the straight toothed rack.

[0008] Preferably, the positioning mechanism includes a lifting plate, a sleeve, a locking bar, a straight toothed rack, an upper pressure block, a gear, a positioning hole, and a spring post. The lifting plate is disposed inside the alloy door body. A straight toothed rack is meshed with one side of the gear. A positioning hole is circumferentially opened on the outer side of the gear. The sleeve is disposed through the outer side of the lifting plate. A spring post is welded to the top of the lifting plate. An upper pressure block is disposed directly above the straight toothed rack. An explosion-proof plate is welded to one side of the upper pressure block.

[0009] Preferably, the handle is connected to a spur rack via a gear connected to one side.

[0010] Preferably, the alloy door body is connected to both sides of the support plate by internally welded spring columns.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. The gear drives the straight toothed rack on one side to mesh and move. The straight toothed rack drives the upper pressure block to apply vertical pressure. On the one hand, it is convenient to vertically guide the locking strip into the interior of the alloy door body, thereby improving the convenience of locking the top of the alloy door body. On the other hand, it is convenient to retract the locking strip into the interior of the alloy door body, avoiding prolonged exposure to air, which could cause corrosion of the locking strip.

[0013] 2. While the gear drives the straight toothed rack on one side to move vertically up and down, the straight toothed rack also drives the explosion-proof plate on one side to move vertically up and down. This increases the impact resistance on one side of the alloy door body, preventing excessive impact from causing the other side of the alloy door body to deform directly after being impacted, and improving the impact resistance of the top of the alloy door body.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 4 As shown, an alloy impact-resistant protective door includes an alloy door body 1. A door handle 2 is connected to one side of the alloy door body 1. Multiple sets of hinges 3 are evenly spaced on one side of the alloy door body 1. A protective mechanism 5 is provided inside the alloy door body 1. The protective mechanism 5 supports and protects the interior of the alloy door body 1, improving the impact resistance of the alloy door body 1. A positioning mechanism 7 is provided at the top of the interior of the alloy door body 1. The positioning mechanism 7 vertically positions the alloy door body 1, thereby preventing the alloy door body 1 from failing to close tightly in the event of a fire, causing smoke to overflow, or preventing the alloy door body 1 from tipping over due to damage to the hinges 3 on one side of the alloy door body 1 caused by a fire.

[0022] In this embodiment, the protection mechanism 5 includes a handle 4, an explosion-proof plate 15, a guide rod 16, and a polyurethane foam board 10. A gear 13 is provided on one side of the handle 4, and an alloy door 1 is connected through one side of the handle 4. A polyurethane foam board 10 is provided inside the alloy door 1, and an explosion-proof plate 15 is provided on the other side of the polyurethane foam board 10. A guide rod 16 is provided directly above the polyurethane foam board 10. The movable explosion-proof plate 15 allows for vertical lifting and displacement within the alloy door 1.

[0023] In this embodiment, a guide rod 16 is provided directly above the polyurethane foam board 10 and is internally connected to the straight toothed rod 11, thereby increasing the fire resistance of the alloy door 1 through the polyurethane foam board 10.

[0024] In this embodiment, the positioning mechanism 7 includes a lifting plate 6, a sleeve 8, a locking bar 9, a straight toothed rack 11, an upper pressure block 12, a gear 13, a positioning hole 14, and a spring column 17. The lifting plate 6 is disposed inside the alloy door body 1. The gear 13 is meshed with the straight toothed rack 11 on one side. The gear 13 has a positioning hole 14 that is circumferentially opened on the outer side. The sleeve 8 is disposed through the outer side of the lifting plate 6. The spring column 17 is welded to the top of the lifting plate 6. The upper pressure block 12 is disposed directly above the straight toothed rack 11. An explosion-proof plate 15 is welded to one side of the upper pressure block 12.

[0025] In this embodiment, the handle 4 is connected to the straight toothed rack 11 by a gear 13 connected to one side. The gear 13 engages with one side of the straight toothed rack 11 to vertically guide the locking bar 9.

[0026] In this embodiment, the alloy door body 1 is connected to both sides of the support plate 6 by internally welded spring columns 17. The spring columns 17 vertically press the support plate 6 upward, making it easy to store the locking strip 9 inside the alloy door body 1 when the locking strip 9 is no longer in use.

[0027] In practical applications, this type of impact-resistant alloy protective door includes the following tasks:

[0028] Step 1: During use, first install the alloy door body 1 and door frame on the building, fix the door frame with concrete, and make a groove of the corresponding size at the position of the locking strip 9 set at the top of the alloy door body 1, so that the locking strip 9 can be inserted into the groove during the lifting and lowering process, thereby vertically positioning the top of the alloy door body 1 and improving the impact resistance of the alloy door body 1.

[0029] Step 2: Before use, install the polyurethane foam board 10 inside the alloy door body 1, and install one side of the explosion-proof plate 15 on the outside of the upper pressure block 12. At the same time, use the guide rod 16 to vertically connect the straight toothed strip 11 and the explosion-proof plate 15 respectively. The explosion-proof plate 15 is used to protect the inside of the alloy door body 1 to avoid the impact force directly causing impact deformation to the alloy door body 1. The impact force is reduced by the explosion-proof plate 15.

[0030] Step 3: When a fire occurs, by holding the handle 4, the gear 13 is rotated. The gear 13 engages with the straight toothed rack 11 on one side, thereby causing the straight toothed rack 11 and the upper pressure block 12 to move vertically upward. This causes the upper pressure block 12 to press against the bottom end of the lifting plate 6 at the top, causing the lifting plate 6 to move vertically upward on the sleeve rod 8. By using the upper pressure block 12 to drive the explosion-proof plate 15 upward, the protective position of the explosion-proof plate 15 is adjusted.

[0031] Step 4: The symmetrically arranged spring columns 17 extend and retract according to the moving position of the upper pressure block 12, thereby adjusting the position of the upper pressure block 12 and the locking strip 9. The locking strip 9 is inserted into the groove opened at the bottom of the building to vertically position the alloy door 1, so as to prevent the hinge 3 on one side of the alloy door 1 from breaking during the impact of a fire or explosion, causing the alloy door 1 to fall and injure people around it.

[0032] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
