Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model embodiment discloses a human defense door which is easy to assemble and splice. Figure 1-6 , a human air defense door that is easy to assemble and splice, comprising a door frame 1, a main door panel 2 is fixedly connected to the inner center of the door frame 1, a cavity 3 is opened inside the main door panel 2, a rotating rod 4 is rotatably connected inside the cavity 3, a fixing mechanism 5 is arranged outside the rotating rod 4, and side door panels 6 are arranged at both left and right ends of the inner side of the door frame 1;

[0024] Reference Figure 4 , Figure 5 and Figure 6 The fixing mechanism 5 includes a disc 501, two connecting rods 502, and two plug plates 503. The disc 501 is fixedly sleeved and connected to the rotating rod 4. The two connecting rods 502 are respectively hinged on the left and right sides of the disc 501, and the two plug plates 503 are respectively hinged on the corresponding connecting rods 502; a fixing opening 11 is provided on the side where the two side door panels 6 are close to each other, and the plug plates 503 are plugged into the fixing opening 11, and a plug opening 12 is provided at the bottom of the side door panels 6. The coordinated use of the fixing mechanism 5 and the fixing opening 11 facilitates the disassembly and assembly of the side door panels 6, making the entire civil defense door easy to transport.

[0025] Reference Figure 6 A plurality of guide grooves 7 are provided inside the cavity 3, and the guide grooves 7 are communicated with the cavity 3. A guide block 8 is slidably connected in the guide groove 7, and one end of the guide block 8 away from the guide groove 7 is connected to the plug plate 503. The coordinated use of the guide grooves 7 and the guide blocks 8 makes the plug plate 503 more stable when moving.

[0026] Reference Figure 4A torsion spring 9 is sleeved on the outer side of the rotating rod 4, and the end of the torsion spring 9 away from the rotating rod 4 is connected to the disc 501. A handle 10 is connected to the front of the main door panel 2, and one end of the handle 10 is connected to the rotating rod 4. The torsion spring 9 allows the plug plate 503 to be stably inserted into the fixing port 11, thereby ensuring the limiting and fixing effect of the side door panel 6.

[0027] Reference Figure 3 The inner bottom end of the door frame 1 is fixedly connected with a plurality of positioning rods 13, and the positioning rods 13 are plugged into the sockets 12. The inner upper end of the door frame 1 is provided with a plurality of movable grooves 14, and the side door panels 6 are easily rotated through the positioning rods 13.

[0028] Working principle: When the utility model is used, when the civil air defense door needs to be spliced ​​and installed, first turn the handle 10 to drive the rotating rod 4 to rotate, the rotating rod 4 rotates to drive the disc 501 to rotate and make the torsion spring 9 twist, the disc 501 rotates through the connecting rod 502 to drive the two plug plates 503 to move closer to each other, and then directly place the side door panel 6 on the inner side of the door frame 1 and move the side door panel 6 upward so that the top of the side door panel 6 is inserted into the movable groove 14, and then align the socket 12 at the bottom of the side door panel 6 with that on the door frame 1, then put down the side door panel 6 so that the socket 12 is inserted into the positioning rod 13 , the placement of the pair of side door panels 6 is completed, and then the handle 10 is released, and the disc 501 is rotated back to the initial position through the torsion spring 9. At this time, the plug plate 503 will be inserted into the fixing hole 11 on the side door panel 6, so that the side door panel 6 can be limited and fixed, and then the splicing and installation of the side door panel 6 is completed without using bolts and tools. When the door needs to be opened, the handle 10 is directly turned to make the plug plate 503 move out of the fixing hole 11 on the side door panel 6, and then the side door panel 6 is rotated to open the door, and the two side door panels 6 can be rotated at the same time, so that the entry and exit range of the civil air defense door is greatly increased.

[0029] When the utility model is in use, the assembly of the side door panels 6 is relatively simple and convenient, and no bolts and tools are needed, so that the civil air defense door is easy to transport. At the same time, the civil air defense door has a larger entry and exit range when opened.
