[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] like Figures 1 to 8 As shown, this utility model provides an impact-resistant, fireproof, and burglarproof door suitable for the construction of a central computer room. It includes a door frame 1, with a fireproof and burglarproof door body 2 hinged to the inside of the door frame 1. The surface of the door frame 1 is provided with a movable component 4 for impact protection of the door body. The movable component 4 includes a first locking rod 42 that can rotate away from the door body 2 or rotate to fit against the door body 2. On the side of the first locking rod 42 away from the door body 2, there is a counter-resistance structure (i.e., a structure that can generate a counter-resistance force opposite to the external impact force of the door body) that can push against the first locking rod 42 under the action of external impact force of the door body.

[0039] Door body 2 is made of hot-dip galvanized steel sheet, which undergoes special fireproofing treatment to maintain structural stability at high temperatures and prevent deformation. Since central computer rooms typically store a large amount of important equipment and data, the fireproof and burglarproof door, with its robust structure and high-quality locks, effectively prevents unauthorized intrusion. Its heavy-duty door body 2 and reinforced door frame 1 can withstand violent damage, providing reliable security for the central computer room, making it suitable for its construction.

[0040] The door frame 1 is equipped with a movable component 4 on its surface inside the central machine room. The anti-collision structure can generate a reverse counterforce on the first locking rod 42 of the movable component 4 when the door is subjected to external impact, thereby achieving the anti-impact effect of the security door during use and increasing the stability and protection of the security door.

[0041] Furthermore, such as Figure 1 , Figure 2 , Figure 7 , Figure 8 As shown, one end of the first locking rod 42 is hinged to one side of the door frame 1. In a specific embodiment, a fixing block 41 is provided on one side of the door frame 1, and one end of the first locking rod 42 is hinged to the fixing block 41. The other end of the first locking rod 42 is connected to a fixing component 3. A positioning block 48 is provided on the other side of the door frame 1. The fixing component 3 at the other end of the first locking rod 42 can be locked and positioned in the positioning block 48 when the first locking rod 42 is in contact with the door body 2. An anti-contact structure is hinged on the positioning block 48.

[0042] The fixing component 3 is locked in place with the positioning block 48, which further restricts the first locking rod 42, improves the stability of the door body 2 when it is impacted, and increases the fixing effect of the door body 2.

[0043] Furthermore, such as Figure 1 , Figure 2 , Figure 3 As shown, the anti-collision structure includes a sliding plate 413 that can slide in a direction perpendicular to the surface of the door body 2. An insert 412 is provided on the side of the sliding plate 413 near the positioning block 48. One end of the insert 412 is slidably inserted into the positioning block 48. Under the action of external impact force, the sliding plate 413 can move away from the door body 2 while driving the insert 412 to move closer to the door body 2 to abut against the first locking rod 42. A second locking rod 414 is hinged to the insert 412. A protective block 415 protruding towards the door body 2 is connected to the second locking rod 414. When the insert 412 moves closer to the door body 2, it drives the second locking rod 414 to move synchronously so that the protective block 415 abuts against the first locking rod 42.

[0044] Furthermore, such as Figure 2 , Figure 3 , Figure 5 As shown, a pivot 49 is hinged to the positioning block 48, a screw 410 is connected to the pivot 49, and a sliding shaft 411 is sleeved on the screw 410. The end of the sliding shaft 411 away from the positioning block 48 is fixedly connected to the insert block 412. An arc groove 490 is provided on the side wall of the pivot 49, and a connecting post is provided on the sliding plate 413. The end of the connecting post away from the sliding plate 413 is inserted into the arc groove 490. The sliding plate 413 can drive the connecting post to move under the action of the external impact force of the door. When the connecting post moves, it can drive the pivot 49 to drive the screw 410 to rotate. When the screw 410 rotates, it drives the sliding shaft 411 to drive the insert block 412 to move.

[0045] Furthermore, such as Figure 2 , Figure 3 As shown, a sliding rod 44 is connected to the first locking rod 42, which can slide in a direction perpendicular to the surface of the door. A limiting block 46 is sleeved on the end of the sliding rod 44 away from the first locking rod 42. An insert plate 47 is connected to the limiting block 46, which is parallel to the length direction of the first locking rod 42. The insert plate 47 can slide with the sliding rod 44 and the limiting block 46 in a direction perpendicular to the surface of the door 2. The end of the insert plate 47 away from the limiting block 46 is inserted into the sliding plate 413. Specifically, a groove 4130 is opened on the surface of the sliding plate 413, and the insert plate 47 is inserted into the groove 4130 so that the insert plate 47 can drive the sliding plate 413 to move.

[0046] Under the impact force from outside the door, the slide bar 44 drives the insert plate 47 and the sliding plate 413 to slide away from the door 2. Under the action of the sliding plate 413, the insert block 412 slides closer to the door 2.

[0047] When the first locking rod 42 rotates, it will cause the connecting block 43 and the limiting block 46 at the bottom of the first locking rod 42 to rotate. The sliding rod 44 is slidably connected inside the connecting block 43. When an external impact force is applied to the door, the sliding rod 44, which is in contact with the surface of the door 2, moves away from the door 2. In turn, the sliding plate 413 is pulled away from the door 2 by the insert plate 47 connected to the limiting block 46.

[0048] When the sliding plate 413 moves, its connecting post slides within the arc-shaped groove 490 on the surface of the rotating shaft 49. The movement of the sliding plate 413 is converted into the rotation of the rotating shaft 49 by the pushing action of the connecting post on the arc-shaped groove 490. The rotating shaft 49 drives the screw 410 to rotate synchronously. Due to the screw-nut structure formed between the screw 410 and the sliding shaft 411, the rotation of the screw 410 is converted into the movement of the sliding shaft 411. The sliding shaft 411 then drives the movement of the connected insert 412. When an external impact force acts on the door, the sliding plate 413 moves away from the door 2. The connecting post pushes the rotating shaft 49 to rotate, causing the sliding shaft 411 to drive the insert 412 to move closer to the positioning block 48. The insert 412 penetrates the positioning block 48 and slides inwards, so its end abuts against the side of the first locking rod 42 away from the door 2. The second locking rod 414, which is hinged to the insert block 412, moves synchronously with it, thereby causing the protective block 415 to abut against the side of the first locking rod 42 away from the door body 2.

[0049] Both the insert block 412 and the protective block 415 exert a counterforce on the first locking rod 42, achieving the anti-impact effect of the security door during use and increasing the stability and protection of the security door.

[0050] Furthermore, such as Figure 2 , Figure 3 As shown, an insertion rod 416 is provided at the end of the second locking rod 414 away from the positioning block 48, and a sliding groove 460 is provided on the limiting block 46. The insertion rod 416 can be inserted into the sliding groove 460, realizing the overlap of the end of the second locking rod 414 away from the positioning block 48. The length of the sliding groove 460 is greater than the cross-sectional length of the insertion rod 416, satisfying the need for the insertion rod 416 to slide inside it.

[0051] Furthermore, such as Figure 2 , Figure 3 As shown, the first locking rod 42 is a multi-layered telescopic rod structure. A connecting block 43 is provided on the outermost layer of the first locking rod 42. A through sliding hole is provided on the connecting block 43. The sliding rod 44 can slide through the sliding hole. A spring 45 is sleeved on the sliding rod 44. The two ends of the spring 45 abut against the connecting block 43 and the limiting block 46, respectively.

[0052] Furthermore, the second locking rod 414 is a multi-layered telescopic rod structure. In one specific embodiment, the second locking rod 414 is a double-layered telescopic rod structure, with the outer section of the second locking rod 414 hinged to the insert block 412.

[0053] Furthermore, such as Figure 4 , Figure 7 , Figure 8 As shown, the fixing component 3 includes a limiting rod 31 connected to the other end of the first locking rod 42. The end of the limiting rod 31 away from the first locking rod 42 is hinged with a plurality of limiting rods 32 that can swing and extend and retract radially along the limiting rod 31. Torsion springs 33 for radial reset of the limiting rods are respectively provided between the limiting rod 31 and each limiting rod 32.

[0054] Furthermore, such as Figure 6 As shown, the positioning block 48 is H-shaped; the positioning block 48 includes a first vertical part and a second vertical part that are parallel to each other, and a first crossbeam part is connected between the first vertical part and the second vertical part. The first vertical part is fixedly connected to the door frame, and a locking through hole is provided on the first crossbeam part. The limiting rod 31 can be inserted through the locking through hole, and the limiting rod 32 can be radially expanded to lock from the bottom of the first crossbeam part.

[0055] When the first locking rod 42 rotates towards the top of the positioning block 48, it will drive the fixing component 3 to rotate synchronously. After rotating into position, the limiting rod 31 and the restricting rod 32 pass through the locking through hole of the positioning block 48. One end of the torsion spring 33 is fixedly installed on the inner side of the restricting rod 32, and the other end of the torsion spring 33 is fixedly installed on the outer side of the limiting rod 31. The restricting rod 32 will be reset under the action of the torsion spring 33, thereby locking onto the bottom of the first crossbeam of the positioning block 48 for fixation. This achieves the H-shaped positioning block 48 resisting and locking the restricting rod 32, preventing the restricting rod 32 from moving, improving the stability of the door body 2 when it is impacted, and increasing the fixing effect of the door body 2.

[0056] The method of using the impact-resistant, fireproof, and burglarproof door of this utility model, suitable for the construction of central computer rooms, is as follows:

[0057] When the security door is in use, the first locking rod 42 hinged on the fixing block 41 can be rotated manually. The connecting block 43, slide rod 44, spring 45, limiting block 46, and insert plate 47 at the bottom of the first locking rod 42 rotate synchronously, pulling the other end of the first locking rod 42 to extend into the positioning block 48. The fixing component 3 is snapped into the positioning block 48. The insert plate 47 is inserted into the inside of the sliding plate 413. At this time, one end of the slide rod 44 is in contact with the surface of the door body 2.

[0058] When the door 2 is impacted, it will move away from the door 2 by resisting the sliding rod 44. This, in turn, will pull the sliding plate 413 away from the door 2 via the insert plate 47 connected to the limiting block 46. As the sliding plate 413 moves away from the door 2, the connecting post on the sliding plate 413 pushes the rotating shaft 49 to rotate, causing the sliding shaft 411 to move the insert block 412 towards the positioning block 48. The insert block 412 passes through the positioning block 48 and slides inward, so its end abuts against the side of the first locking rod 42 away from the door 2, thus restricting the door 2. The second locking rod 414, hinged to the insert block 412, moves synchronously with it, causing the protective block 415 to abut against the side of the first locking rod 42 away from the door 2. Both the insert block 412 and the protective block 415 exert opposing resisting forces on the first locking rod 42, achieving the impact-resistant effect of the security door during use and increasing the stability and protection of the security door.

[0059] As described above, the impact-resistant, fireproof, and burglarproof door of this utility model, suitable for the construction of central computer rooms, has the following characteristics:

[0060] Beneficial effects:

[0061] The door frame of this utility model is provided with a movable component. The anti-collision structure can generate a reverse anti-collision force on the first locking rod of the movable component when the door is subjected to external impact. The first locking rod abuts against and presses against the door, realizing the impact resistance effect of the security door during use and increasing the stability and protection of the security door.

[0062] The fixing component and positioning block of this utility model are locked and positioned, further restricting the first locking rod, improving the stability of the door when it is impacted, and increasing the door fixing effect.

[0063] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
