They are clearly classified into ordinary single-leaf and double-leaf protective closed doors and closed doors, movable threshold single-leaf and double-leaf protective closed doors and closed doors, etc. They can block the intrusion of shock waves, toxic gases and other harmful substances according to actual needs.

[0003] When producing civil air defense doors, some are made by welding steel structures, and some are made by pouring concrete in steel structure frames. No matter which method is used to make civil air defense doors, they will be large in size and heavy in weight.

[0004] When installing civil air defense doors, general underground civil air defense projects have large overall size and heavy weight. When construction workers move the civil air defense doors, due to their large size, turning and moving are more difficult when using engineering vehicles to move them. At the same time, when installing civil air defense doors, construction workers need to reserve hooks on the building, and use ropes to pass through the hooks to lift the entire civil air defense door, and then install it. It is inconvenient for construction workers to use equipment to move and install civil air defense doors. Summary of the invention

After the resistance block is inserted into the resistance groove, the fixed threaded rod is inserted into the positioning cone head and threadedly connected. At the same time, the fixed block is in resistance on the splicing frame, so that the positioning cone head is firmly inserted into the splicing frame to complete the installation of module door two and module door three. Then, the same operation steps are used to install module door one on module door two, so that the civil air defense door can be modularly assembled on site, which can facilitate the transportation and handling of the civil air defense door, reduce the possibility of the civil air defense door being too heavy and too large to cause inconvenience in transportation and installation, and at the same time, it can facilitate assembly and reduce the gap caused by assembly.

Mechanism 5 fixes module door 1 to module door 2 2. While module door 1 is fixed to sealing door 2, the gap between module door 1 and module door 2 2 is sealed by means of resistance sealing mechanism 6, and the connection between module door 1 1 and module 2 is further strengthened. Module door 1 1, module door 2 2 and module door 3 3 are spliced ​​and fixed at the installation site by means of splicing and fixing mechanism 5. While splicing and fixing, the gap between module door 1 1 and module door 2 2, and the gap between module door 2 2 and module door 3 3 are sealed by means of resistance sealing mechanism 6, and further reinforced. This enables the civil air defense doors to be modularly assembled on site, facilitates the transportation and handling of the civil air defense doors, and reduces the possibility of inconvenience in transportation and installation due to the civil air defense doors being too heavy and too large.

[0031] Reference Figure 2 , Figure 3 and Figure 3 The splicing and fixing mechanism 5 includes two splicing blocks 51 arranged between module door 1 and module door 2, module door 2 and module door 3, the two splicing blocks 51 are fixedly connected with the corresponding module door 1 and module door 2, a positioning cone head 53 is fixed on the splicing block 51, a splicing frame 52 is arranged between module door 1 and module door 2, module door 2 and module door 3, the two splicing frames 52 are fixedly connected with the corresponding module door 2 and module door 3, the positioning cone head 53 corresponds to the splicing frame 52, and a fixing component 54 is arranged between the positioning cone head 53 and the splicing frame 52.

[0032] When connecting module door 1 and module door 2, and module door 2 and module door 3, first install module door 3 on the door frame using mounting block 7, then face the side of module door 2 with splicing block 51 toward module door 3, then insert the positioning cone head 53 on splicing block 51 on module 2 into splicing frame 52, align splicing block 51 and splicing frame 52 using positioning cone head 53, align module door 2 and module door 3, then use fixing assembly 54 to fix corresponding splicing block 51 and splicing frame 52 together, thus completing the fixed connection between module door 2 and module door 3. When module door 1 is installed on module door 2 2, the same operation is performed to complete the splicing and fixing of module door 1 1, module door 2 2 and module door 3 3, and complete the assembly of the civil air defense door. When installing the civil air defense door, the adjacent module door 1 1 and module door 2 2, module door 2 2 and module door 3 3 are fixed by using splicing blocks 51 and splicing frames 52, so that module door 1 1, module door 2 2 and module door 3 3 are modularly fixed and installed, thereby facilitating the transportation of the civil air defense door, reducing the possibility of inconvenience in transportation due to excessive volume and weight of the civil air defense door, and facilitating the installation of module door 1 1, module door 2 2 and module door 3 3.

[0033] Reference Figure 2 and Figure 4 The fixing assembly 54 includes a fixing threaded rod 542 threadedly connected to the end of the positioning cone head 53 away from the splicing block 51, the fixing block 541 is rotatably connected to the fixing threaded rod 542, and a rotating disk 543 is fixed to the end of the fixing threaded rod 542 away from the splicing block 51. After the positioning cone head 53 on the splicing block 51 is inserted into the splicing frame 52, the fixed threaded rod 542 is inserted into the positioning cone head 53, and the rotating disk 543 is rotated to allow the rotating disk 543 to drive the fixed threaded rod 542 to be threadedly connected with the positioning cone head 53. At the same time, the fixed block 541 is in contact with the splicing frame 52, so that the positioning cone head 53 is firmly inserted into the splicing frame 52. By inserting the positioning cone head 53 on the splicing block 51 into the splicing frame 52, and then using the fixed threaded rod 542 to connect with the positioning cone head 53, the fixed threaded rod 542 drives the fixed block 541 to contact the splicing frame 52, so that the splicing block 51 and the splicing frame 52 can be fixed together.

[0034] Reference Figure 2 and Figure 4A positioning block 544 is fixed to one side of the fixed block 541 close to the splicing frame 52, and a positioning groove corresponding to the positioning block 544 is provided on the splicing block 51. When the fixed block 541 contacts the splicing frame 52, the positioning block 544 on the fixed block 541 is inserted into the positioning groove on the splicing frame 52, so that the fixed block 541 will not be rotated by the fixed threaded rod 542 when contacting the splicing frame 52. By inserting the positioning block 544 on the fixed block 541 into the positioning groove on the splicing frame 52, the possibility of the fixed block 541 rotating with the fixed threaded rod 542 can be reduced.

[0035] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6 The contact sealing mechanism 6 includes two contact blocks 61 arranged between module door 1 and module door 2, and module door 2 and module door 3. The two contact blocks 61 are fixedly connected to the corresponding module door 1 and module door 2. The module door 2 and module door 3 are both provided with contact grooves 62 corresponding to the contact blocks 61. An extrusion sealing component 63 is provided on the contact block 61. A reinforcement component 64 is provided between the module door 1 and the module door 3.

[0036] After the module door 3 is installed, while the module door 2 and the module 3 are fixed together by the splicing block 51 and the splicing frame 52, the module door 2 with the resistance block 61 is inserted into the resistance groove 62 on the module door 3, and the resistance block 61 directly resists and squeezes the sealing component 63, so that the resistance sealing component extends out and the resistance sealing component resists the inner wall of the resistance groove 62, so that the gap between the module door 2 and the module door 3 is sealed. When installing and fixing the module door 1, the operation is the same. After the module door 1, the module door 2 and the module door 3 are installed, the reinforcement component is finally used. 64 reinforces and fixes module door one 1, module door two 2 and module door three 3 by inserting the abutment block 61 into the abutment groove 62 while using the splicing block 51 and the splicing frame 52 to fix module door one 1 to module door two 2, module door two 2 to module door three 3, and allowing the extrusion sealing assembly 63 to abut against the inner wall of the abutment groove 62, thereby further improving the stability of the fixation between module door one 1 and module door two 2, module door two 2 and module door three 3, and reducing the gap between module door one 1 and module door two 2, and between module door two 2 and module door three 3.

[0037] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6The extrusion sealing assembly 63 includes an extrusion block 631 slidably connected to the resistance block 61, a sealing block 632 is slidably connected to the resistance block 61, an inclined surface is provided at one end of the sealing block 632 close to the extrusion block 631, the extrusion block 631 is in contact with the inclined surface of the sealing block 632, a sealing groove 633 corresponding to the sealing block 632 is provided in the resistance groove 62, and a resistance sealing strip 634 is fixed on the sealing block 632.

[0038] When the resistance block 61 is inserted into the resistance groove 62, the extrusion block 631 on the resistance block 61 is in contact with the inner wall of the resistance groove 62, and then the extrusion block 631 slides into the resistance block 61, and then the extrusion block 631 squeezes the inclined surface of the sealing block 632, so that the sealing block 632 extends out from the resistance block 61, and then the sealing block 632 drives the resistance sealing strip 634 to be inserted into the sealing groove 633 on the inner wall of the resistance groove 62. By allowing the extrusion block 631 to drive the sealing block 632 to be inserted into the sealing groove 633 under the extrusion of the resistance block 61, the gap between the module door 1 and the module door 2, and between the module door 2 and the module door 3 can be reduced, and the stability of the connection can be further improved.

[0039] Reference Figure 3 and Figure 6 A plurality of evenly distributed support springs 635 are arranged between the extrusion block 631 and the resistance block 61, and both ends of the support spring 635 are fixedly connected to the extrusion block 631 and the resistance block 61. When the resistance block 61 has not been inserted into the resistance groove 62, the support spring 635 is used to support the extrusion block 631, so that the extrusion block 631 remains in a state of extending out on the resistance block 61, and the sealing block 632 remains in a state of contracting into the resistance block 61. When the resistance block 61 is inserted into the resistance groove 62, the extrusion block 631 pushes the support spring 635 and pushes the sealing block 632 out of the resistance block 61. By supporting the extrusion block 631 with the support spring 635, the possibility that the extrusion block 631 moves to push the sealing block 632 out of the resistance block 61 when the resistance block 61 has not been inserted into the resistance groove 62 can be reduced, and the possibility that the resistance block 61 is blocked by the sealing block 632 and cannot be inserted into the resistance groove 62 can be reduced.

[0040] Reference Figure 1 and Figure 2 The reinforcement component 64 includes two reinforcement blocks 641 respectively fixed on the module door 1 and the module door 3, and the two reinforcement blocks 641 are slidably connected with a reinforcement threaded rod 642. A limiting block 643 is fixed to one end of the reinforcement threaded rod 642 close to the reinforcement block 641, and a threaded sleeve 644 is threadedly connected between the two reinforcement threaded rods 642.

[0041] After fixing module door 1, module door 2, and module door 3, two reinforcing threaded rods 642 are respectively inserted into the reinforcing blocks 641 on module door 1 and module door 2, and then, between the two reinforcing threaded rods 642, use threaded sleeves 644 to connect the two reinforcing threaded rods 642, so that the two reinforcing threaded rods 642 are close to each other, and then the two reinforcing threaded rods 642 drive the corresponding limit blocks 643, so that the limit blocks 643 are in contact with the reinforcement blocks 641, and the reinforcement blocks 641 drive module door 1 and module 3 to move closer to the middle. By driving the threaded sleeves 644, the two reinforcing threaded rods 642 drive the reinforcement blocks 641 to move closer to the middle, thereby further improving the stability between module door 1, module door 2, and module door 3, and improving the durability of the entire civil defense door.

[0042] Working principle: First, all module door 1, module door 2, and module door 3 are produced in the factory, and then module door 1, module door 2, and module door 3 are transported to the location where the civil air defense door needs to be installed, and then the mounting block 7 on module door 3 is used to install module door 3 on the corresponding door frame, and then the side of module door 2 with the splicing block 51 fixed is facing module door 3, and then the positioning cone head 53 on the splicing block 51 on module 2 is inserted into the splicing frame 52, and the positioning cone head 53 is used to align the splicing block 51 and the splicing frame 52, and the module door 2 and module door 3 are aligned, and at the same time, the module door 2 is inserted into the contact groove 62 on the module door 3 with the contact block 61, and the extrusion block 631 on the contact block 61 contacts the inner wall of the contact groove 62, and then the extrusion block 631 slides into the resistance block 61, and then the extrusion block 631 squeezes the inclined surface of the sealing block 632 to allow the sealing block 632 to extend from the resistance block 61, and then the sealing block 632 drives the resistance sealing strip 634 to be inserted into the sealing groove 633 on the inner wall of the resistance groove 62, and the positioning cone head 53 on the splicing block 51 is inserted into the splicing frame 52. After the resistance block 61 is inserted into the resistance groove 62, the fixed threaded rod 542 is inserted into the positioning cone head 53 and threadedly connected. At the same time, the fixed block 541 is in contact with the splicing frame 52, so that the positioning cone head 53 is firmly inserted into the splicing frame 52, completing the installation of module door 2 2 and module door 3 3, and then use the same operation steps to install module door 1 1 on module door 2 2, so that module door 1 1, module door 2 2 and module door 3 3 form a civil defense door.

[0043] After fixing module door 1 1, module door 2 2 and module door 3 3, insert two reinforcing threaded rods 642 into the reinforcing blocks 641 on module door 1 1 and module door 2 2 respectively, and then use threaded sleeve 644 to connect the two reinforcing threaded rods 642 between the two reinforcing threaded rods 642, so that the two reinforcing threaded rods 642 are close to each other, and then the two reinforcing threaded rods 642 drive the corresponding limit blocks 643, so that the limit blocks 643 are in contact with the reinforcing blocks 641, and the reinforcing blocks 641 drive module door 1 1 and module 3 to move closer to the middle, so as to further fix module door 1 1, module door 2 2 and module door 3 3.
