When the civil defense door is damaged or deformed, the civil defense door can be disassembled, replaced or repaired without the need to scrap the entire civil defense door.
[0004] However, this patent still has certain shortcomings in actual use. During the installation or disassembly process, the civil air defense door needs to complete the limiting operation through the cooperation between the threaded rod and the threaded block and the power gear and the transmission gear. The civil air defense door will not be dismantled for a period of time after installation. As a result, the limiting function achieved by the patent through the cooperation of the above-mentioned multiple transmission structures is not used for a long time. For infrequent operations, the same effect can be achieved by relying on a simple structure. In this regard, the present application proposes a quick-assembly civil air defense door based on cost reduction and structural simplification to solve the above problems. Utility Model Content

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0031] See also Figures 1 to 4 , the present application provides a technical solution: a quick-assembly civil air defense door, comprising a door frame main body 1, the inner side of the door frame main body 1 is movably connected to a civil air defense door main body 2, and an assembly component 400 that can be connected to the door frame main body 1 is installed on the left side of the civil air defense door main body 2; through the coordinated use of the civil air defense door main body 2 on the outside of the door frame main body 1 and the assembly component 400, the limiting structure can be greatly simplified while ensuring that the civil air defense door has a quick assembly function, so that the civil air defense door can be assembled simply and quickly to meet the requirements of positioning and installation. Through simple operating instructions, non-professionals can also complete the deployment and installation of the civil air defense door in a short time, and can also start the sliding support of the civil air defense door during the rotation opening or closing process, so that the convenience of opening or closing the civil air defense door is further improved, thereby effectively improving the practicality of quick assembly of the civil air defense door.
[0032] In this embodiment, the assembly component 400 is a structure used to quickly assemble the civil defense door body 2 through the cooperation between simple structures.
[0033] like Figure 2 、 Figure 3 and Figure 4As shown, the assembly component 400 includes two plug-in blocks 401, both of which are hinged to the left side of the front face of the civil defense door body 2 through hinges, two plug-in slots 402 opened on the front face of the door frame body 1 and respectively for the two plug-in blocks 401 to be plugged in, a sliding slot 403 opened at the bottom of the plug-in block 401, a clamping block 404 slidably connected to the inner side of the sliding slot 403, a pushing plate 405 fixed on the front face of the clamping block 404, a pushing hole 406 opened on the front face of the plug-in block 401 and for the corresponding pushing plate 405 to slide, two clamping cavities 407 opened inside the door frame body 1 and connected to the interior of the corresponding plug-in slots 402, two docking grooves 408 opened on the front face of the door frame body 1 and connected to the interior of the corresponding clamping cavities 407, four threaded grooves 409 opened on the front faces of the two clamping blocks 404, and bolts 410 threadedly connected to the inner side of the threaded grooves 409.
[0034] It should be noted that the interior of the pushing hole 406 is connected to the interior of the sliding groove 403, so that the pushing plate 405 can normally drive the clamping block 404 to move inside the sliding groove 403, and the two clamping cavities 407 are respectively used for the two clamping blocks 404 to be plugged in, so that the clamping blocks 404 can be plugged into the interior of the corresponding clamping cavity 407 to achieve the positioning effect.
[0035] In addition, the top of the docking groove 408 is open, and the interior of the docking groove 408 is connected to the interior of the plug-in groove 402. The height of the snap-fit block 404 is less than the sum of the height of the docking groove 408 and the height of the corresponding sliding groove 403, so that when the snap-fit block 404 slides to the top of the sliding groove 403, its bottom can be located inside the docking groove 408, thereby facilitating the snap-fit block 404 to be inserted into the corresponding snap-fit cavity 407.
[0036] At the same time, the end of the bolt 410 passes through the front of the door frame body 1 and is connected to the inner thread of the corresponding thread groove 409, so that the bolt 410 can be connected to the inner thread of the corresponding thread groove 409, thereby fixing the clamping block 404 and the door frame body 1, and completing the assembly of the civil defense door body 2. The outer side of the plug-in block 401 is square, and the inside of the plug-in groove 402 is connected to the inner side of the door frame body 1, so that the plug-in block 401 can be normally driven by the civil defense door body 2 to be plugged into the inner side of the corresponding plug-in groove 402, and the square setting can improve the stability of the plug-in. The civil defense door body 2 is quickly assembled on the inner side of the door frame body 1, so that the staff can quickly engage in other work after the assembly work is completed, so as to improve the overall work efficiency. The structure used is simple, and even if it is not used for a long time, it will not generate too much additional cost, so that the cost can be used in more valuable structures, thereby improving the stability of the civil defense door body 2. In the assembly process, two people are required to cooperate in the operation, which is in line with the number of two or more workers in industrial operations. It can prevent abnormal situations when a single person operates alone and there are no people around to assist, thereby improving work safety.
[0037] It should also be noted that if Figure 1 As shown, a door lock 301 is fixedly installed between the front of the civil defense door body 2 and the front of the door frame body 1, a fixing plate 302 is fixed to the front of the civil defense door body 2, and a support pulley 303 is fixedly installed at the bottom of the fixing plate 302. The fixing plate 302 is located on the side of the front of the civil defense door body 2 away from the plug-in block 401, and the bottom of the support pulley 303 is in contact with the ground, so that the support pulley 303 can support the side of the civil defense door body 2 away from the plug-in block 401, so that the civil defense door body 2 can be opened or closed smoothly.
[0038] The working principle of the above embodiment is:
[0039] When assembling the civil defense door, move the civil defense door body 2 to the outside of the door frame body 1, lift the two pushing plates 405 so that the card block 404 can move to the inside of the corresponding sliding groove 403, move the civil defense door body 2 to the inside of the door frame body 1, and make the two plug-in blocks 401 respectively plugged into the inner sides of the two plug-in grooves 402, and the bottom of the card block 404 can be transitioned through the docking groove 408 so that it can move normally to the inside of the card cavity 407, loosen the pushing plate 405, so that the card block 404 is plugged into the inner side of the card cavity 407, and finally thread the bolt 410 into the inner side of the corresponding threaded groove 409, and the assembly of the civil defense door body 2 can be completed so that it can be used normally. In the process of opening or closing, the support pulley 303 can support the side of the civil defense door body 2 away from the plug-in block 401, so that the civil defense door body 2 can be opened or closed smoothly and stably.
[0040] Compared with the existing technology, the quick-assembly civil defense door, through the coordinated use of the civil defense door body 2 outside the door frame body 1 and the assembly component 400, can greatly simplify the limiting structure while ensuring that the civil defense door has a quick assembly function, so that the civil defense door can be assembled simply and quickly to meet the needs of positioning installation. Through simple operating instructions, non-professionals can also complete the deployment and installation of the civil defense door in a short time, and can also start the sliding support of the civil defense door during the rotation opening or closing process, so that the convenience of opening or closing the civil defense door is further improved, thereby effectively improving the practicality of the quick-assembly civil defense door, and solving the shortcomings of the existing easy-to-install civil defense door that can be easily installed but requires more transmission structures and is not frequently used, which increases the overall cost.
