[0002] Civil defense, also known as civil defense, is an internationally recognized term. It refers to the activities of the government in mobilizing and organizing the masses to take measures to prevent air raids, combat disasters and provide relief, carry out rescue operations, and prevent and mitigate the harm of disasters.

[0003] Civil defense doors are the doors at the entrances and exits of civil defense projects. Civil defense doors are classified in a relatively clear manner, including ordinary single and double-leaf protective airtight doors and airtight doors, as well as single and double-leaf protective airtight doors and airtight doors with movable thresholds, and other types of civil defense equipment.

[0004] Existing air-raid shelter doors have a certain degree of impact resistance, but their impact resistance is weak, and they are cumbersome to operate and cannot withstand large impacts. Utility Model Content

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An impact-resistant air defense door includes a door frame, a door panel hinged to the inner side of the door frame, an impact-resistant component at the front end of the door panel, a fixing mechanism at the rear end of the door panel, and symmetrical insertion holes on the upper and lower inner walls of the door frame.

[0007] The fixing mechanism includes a slot, which is opened inside the rear end of the door panel. A double-acting screw is rotatably installed in the middle of the slot. A conical wheel is fixedly sleeved in the middle of the double-acting screw. Threaded seats are threaded on both the upper and lower ends of the double-acting screw. Side rods are symmetrically fixed on both inner walls of the slot. A sliding rod is fixed at the top of the side rod. Moving seats are slidably sleeved on both the upper and lower ends of the sliding rod. A cross plate is fixed between the moving seat and the threaded seat. A support rod is fixed at one end of the moving seat. A pin is fixed at the top of the support rod. Through holes are symmetrically opened through the upper and lower inner walls of the slot.

[0008] Preferably, the rear end of the door panel is fixedly provided with a housing, the middle of the housing is rotatably provided with a rotating rod, the top end of the rotating rod is fixedly provided with a knob, the bottom end of the rotating rod is fixedly provided with a conical wheel, the front end of the rotating rod is fixedly sleeved with a toothed ring, the upper end of the housing is threadedly installed with a screw, and the lower end of the screw is rotatably installed with a clamping plate.

[0009] Preferably, the through hole is formed at both the upper and lower ends of the door panel, the insert post is movably installed through the inside of the through hole, and the support rod is arranged in an "L" shape.

[0010] Preferably, the second conical wheel meshes with the first conical wheel, and the bottom end of the rotating rod can pass through the rear end of the door panel and extend into the slot.

[0011] Preferably, the clamping plate is semi-arc-shaped and meshes with the toothed ring, which can be used to limit the rotation rod.

[0012] Preferably, the impact-resistant component includes a mounting groove, which is formed inside the front end of the door panel. A reinforcing steel plate is fixedly installed inside the mounting groove, and reinforcing ribs are fixedly installed inside the reinforcing steel plate. An impact plate is fixedly installed at the front end of the reinforcing steel plate.

[0013] Preferably, the impact plate is fixedly bonded with a rubber pad. Under the action of the reinforcing steel plate and the reinforcing rib, the door panel has better impact resistance and will not be easily damaged under external impact, thereby improving the safety of the evacuation door.

[0014] Preferably, the insertion hole and the through hole have the same size, the insertion post can pass through the through hole and fit into the insertion hole, and can be installed movably.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model provides an impact-resistant air defense door. Through the impact-resistant components, and with the help of reinforced steel plates and reinforcing ribs, the door panel has better impact resistance and will not be easily damaged under external impact, thereby improving the safety of the air defense door.

[0017] 2. This utility model provides an impact-resistant air-raid shelter door. Through a fixing mechanism, a rotating bidirectional screw can drive the threaded seats on the upper and lower sides to move away from each other. This allows the threaded seats to slide synchronously on the slide rod via a horizontal plate, thereby causing the support rod to push the insertion post to move. This allows the insertion post to pass through the through hole on the door panel and directly insert into the insertion hole in the door frame, thus effectively increasing the impact resistance of the air-raid shelter door. At the same time, through the engagement of the locking plate and the toothed ring, the rotating rod can be limited to prevent it from rotating on its own, thereby effectively preventing the displacement of the insertion post. In this way, the door frame and the door panel are firmly connected, which can further increase the impact resistance of the door. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] like Figures 1-5 As shown, this utility model provides an impact-resistant air defense door, including a door frame 1, a door panel 2 hinged to the inner side of the door frame 1, an impact-resistant component 3 at the front end of the door panel 2, a fixing mechanism 4 at the rear end of the door panel 2, and insertion holes 5 symmetrically opened on the upper and lower inner walls of the door frame 1.

[0026] The insertion hole 5 and the through hole 411 have the same size. The insertion post 410 can pass through the through hole 411 and fit into the insertion hole 5, and can be installed movably.

[0027] In this design, the door panel 2 of the air-raid shelter door possesses excellent impact resistance thanks to the impact-resistant component 3. Even when subjected to strong external impacts, the door panel 2 will not easily suffer structural damage and can always maintain its complete protective form. Through the fixing mechanism 4, the door frame 1 and the door panel 2 achieve a highly secure connection. The stable embedding of the insert post 410 and the reliable limiting of the locking plate 418 complement each other, not only preventing loosening between the door panel 2 and the door frame 1, but also forming a rigid whole between the two, further improving the protective effect of the air-raid shelter door.

[0028] like Figures 4-5As shown, the fixing mechanism 4 includes a slot 41, which is located inside the rear end of the door panel 2. A bidirectional lead screw 42 is rotatably mounted in the middle of the slot 41. A conical wheel 43 is fixedly sleeved in the middle of the bidirectional lead screw 42. Threaded seats 44 are threaded onto both the upper and lower ends of the bidirectional lead screw 42. Side rods 45 are symmetrically fixed on both sides of the inner wall of the slot 41. A sliding rod 46 is fixed at the top of the side rod 45. Moving seats 47 are slidably sleeved onto both the upper and lower ends of the sliding rod 46. A cross plate 48 is fixed between the moving seat 47 and the threaded seat 44. A support rod 49 is fixed at one end of the moving seat. A pin 410 is fixed at the top of the support rod 49. Through holes 411 are symmetrically opened through the upper and lower inner walls of the slot 41.

[0029] A housing 413 is fixedly installed on the rear end of the door panel 2. A rotating rod 414 is rotatably installed in the middle of the housing 413. A knob 415 is fixedly installed at the top of the rotating rod 414. A conical wheel 412 is fixedly installed at the bottom of the rotating rod 414. A toothed ring 416 is fixedly sleeved on the front end of the rotating rod 414. A screw 417 is threadedly installed on the upper end of the housing 413. A clamping plate 418 is rotatably installed on the lower end of the screw 417.

[0030] Through holes 411 are opened at both ends of the door panel 2. Insert post 410 is installed through the inside of through hole 411. Support rod 49 is set in an "L" shape.

[0031] Conical wheel 412 meshes with conical wheel 43, and the bottom end of rotating rod 414 can pass through the rear end of door panel 2 and extend into slot 41.

[0032] The clamping plate 418 is semi-circular in shape and meshes with the toothed ring 416, which can be used to limit the rotation rod 414.

[0033] In this design, after the insert 410 is fully inserted into the insertion hole 5, the screw 417 can be rotated to push the retaining ring downwards, causing the retaining ring to mesh with the toothed ring 416 on the rotating rod 414 inside the outer casing 413. This limits the rotation of the rotating rod 414, preventing it from rotating on its own and avoiding the rotation of the first conical wheel 43 and the second conical wheel 412. This prevents the insertion 410 from shifting and ensures that the insertion 410 is always in the optimal position for insertion into the insertion hole 5 of the door frame 1. Conversely, the retaining plate 418 separates from the toothed ring 416, making it easier for the knob 415 to rotate the second conical wheel 412 using the rotating rod 414. This facilitates the threaded seats 44 to move closer together, allowing the insertion 410 to separate from the insertion hole 5. This makes it easier to release the door panel 2 from the door frame 1 and open the door panel 2.

[0034] In this design, the movable seat 47 slides smoothly and synchronously on the slide rod 46, and the slide rod 46 provides precise guidance for the movable seat 47, ensuring that its movement trajectory does not deviate.

[0035] like Figure 3 As shown, the impact-resistant component 3 includes a mounting groove 31, which is opened inside the front end of the door panel 2. A reinforcing steel plate 32 is fixedly installed inside the mounting groove 31, and a reinforcing rib 33 is fixedly installed inside the reinforcing steel plate 32. An impact plate 34 is fixedly installed at the front end of the reinforcing steel plate 32.

[0036] The impact plate 34 is fixedly bonded with a rubber pad. With the help of the reinforcing steel plate 32 and the reinforcing rib 33, the door panel 2 has better impact resistance and will not be easily damaged under external impact, thereby improving the safety of the security door.

[0037] In this solution, the reinforcing steel plate 32 is made of high-strength alloy material, which has extremely high hardness and toughness. The reinforcing ribs 33 are welded to the inner side of the reinforcing steel plate 32 in a crisscross pattern, which further optimizes the stress structure of the door panel 2. The rubber pads set on the impact plate 34 release the impact force first, and then transfer the remaining force to the reinforcing steel plate 32 and the reinforcing ribs 33, thus forming a multi-level protection.

[0038] The working principle of this impact-resistant air defense door will be explained in detail below.

[0039] like Figures 1-5 As shown, when the impact-resistant safety door is in use, after the door panel 2 is closed, the knob 415 can be rotated, causing the knob 415 to drive the second conical wheel 412 to rotate via the rotating rod 414. The second conical wheel 412, through the meshing first conical wheel 43, drives the double-acting screw 42 in the internal slot 41 of the door panel 2 to rotate. During the rotation of the double-acting screw 42, the threaded seats 44 on its upper and lower sides can move away from each other. At this time, the threaded seats 44, through the horizontal plate 48, will drive the movable seat 47 to slide smoothly and synchronously on the sliding rod 46. As the movable seat 47 slides, the support rod 49 connected to it is pushed, thereby driving the insert 410 to move synchronously. Under the thrust of the support rod 49, the insert post 410 can accurately pass through the pre-set through hole 411 on the door panel 2 and directly insert into the corresponding insertion hole 5 in the door frame 1. With the simultaneous embedding of multiple sets of insert posts 410, the bonding strength between the two is greatly improved, thereby effectively increasing the overall impact resistance of the blast door. Even when faced with strong external impact, the door panel 2 is not easy to move relative to the door frame 1. When the impact plate 34 is hit, the door panel 2 has better impact resistance under the action of strong steel plate and reinforcing rib 33, and the structure will not be easily damaged under external impact, thereby improving the safety of the blast door.

[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
