Description

Technical Field

[0001] The utility model relates to the technical field of construction devices for civil air defense doors, and particularly relates to a hinge protection device for civil air defense doors. Background Art

[0002] A civil air defense door generally includes a civil air defense door frame, a civil air defense door leaf and a hinge. The civil air defense door frame and the civil air defense door leaf are rotationally connected through the hinge. For example, Patent CN209469299U discloses a double-leaf civil air defense door, which includes a door frame and two civil air defense door leaves. Each civil air defense door leaf and the door frame are connected through a hinge, and a support assembly for preventing the civil air defense door leaf from deforming is arranged on one side of the civil air defense door leaf. The support assembly includes a fixed sleeve, a screw rod and a hand wheel. By arranging the screw rod and the fixed sleeve, the screw rod is in threaded cooperation with the fixed sleeve, and the screw rod abuts against the ground, which plays a supporting role for the civil air defense door leaf, can avoid the civil air defense door leaf from sagging and deforming due to its own weight, and improves safety.

[0003] During construction, the civil air defense door frame and the civil air defense door leaf are installed separately. First, the civil air defense door frame is connected to the wall steel bars during the binding of the wall steel bars, and then concrete is poured. After the concrete solidifies, the civil air defense door leaf is installed.

[0004] Since the base of the hinge is usually integrally arranged with the civil air defense door frame, when embedding the civil air defense door frame, a space for installing the hinge body and the suspended plate hinge needs to be reserved in front of the base. However, during the construction of steel bar binding or concrete pouring, there is often a problem that the installation space of the hinge body and the suspended plate hinge is accidentally occupied, which is not conducive to the installation of the civil air defense door leaf.

[0047] In one embodiment, a plurality of second adjustment holes 112a are provided at intervals along the arrangement direction of the two sets of pressing plates 12 on the second adjustment plate 112. The pressing plate 12 is provided with second limit posts 121 corresponding to the second adjustment holes 112a, and the second limit posts 121 are selectively inserted into the second adjustment holes 112a.

[0048] In this embodiment, similarly, through the cooperation of the second limit posts 121 and the second adjustment holes 112a, after the pressing plate 12 presses the second adjustment plate 112 well, the second adjustment plate 112 can be effectively restricted from shifting, further improving the stability of the device.

[0049] In one embodiment, the adjustment plate 11 and the pressing plate 12 are respectively provided with magnetizable members to be magnetically attracted to the hinge base.

[0050] In this embodiment, magnetizable members are respectively provided on the adjustment plate 11 and the pressing plate 12, so that when installing, the adjustment plate 11 and the pressing plate 12 can be respectively magnetically attracted to the hinge base first, improving the assembly convenience. It should be noted that, in one embodiment, the adjustment plate 11 and the pressing plate 12 are made of magnetic materials to integrally form magnetizable members.

[0051] In one embodiment, the connecting arm 4 includes a first arm body 41, a second arm body 42 and a limit pin. The first arm body 41 is connected to the adjustment plate 11 and is provided with a movable channel along the direction away from the adjustment plate 11. The side wall of the movable channel is provided with pin holes 41a communicating with the outside. A plurality of pin holes 41a are provided at intervals along the extending direction of the movable channel.

[0058] For a better understanding of the present invention, the following will Figures 1 to 7 describe the technical solution of the present invention in detail:

[0059] In this solution, before embedding the civil air defense door frame 6, first pass the fixing bolt 21 through the communication hole 1a of the pressing plate 12 and screw it into the fixing screw hole 7a. Then, according to the spacing of the fixing screw holes 7a, insert the first limiting post 113 into the corresponding first adjusting hole 111a and insert the second limiting post 121 into the corresponding second adjusting hole 112a, so that the overall size of the adjusting seat meets the spacing requirements of the fixing screw holes 7a. Then, through the movable second arm body 42, make the connecting arm 4 meet the size requirements of the cover body 3, so that the second arm body 42 can press against the side of the cover body 3 away from the fixed seat 1, and then fix the cover body 3 on the connecting arm 4 through the locking bolt 51, thus completing the protection of the hinge base and providing a suitable installation space for the hinge main body and the hanging plate hinge 9. After the concrete is poured and solidified to a certain extent, remove the locking bolt 51 and the fixing bolt 21, and the disassembly of the cover body 3 and the fixed seat 1 can be completed, which is convenient for the installation of the hinge main body and the hanging plate hinge 9.
