Example one

Referring to fig. 1 to 3, the reinforced concrete civil air defense door leaf hook structure of the embodiment includes a mounting base 210, a door leaf hook 220, and a bolt 310, wherein the mounting base 210 is mounted on the door leaf 100, a mounting threaded hole 211 is formed in the mounting base 210, a hook through hole 223 is formed in a position corresponding to the mounting threaded hole 211 of the door leaf hook 220, the bolt 310 passes through the hook through hole 223 and then is assembled with the mounting threaded hole 211 in a screwing manner, so that the door leaf hook 220 is mounted on the mounting base 210, a hook portion 221 is formed on the door leaf hook 220, and a through hanging hole 222 is formed on the hook portion 221. In use, the lifting hook or the lifting object can be tightly sleeved on the lifting hole 222, and then the whole door leaf 100 is lifted by the door leaf lifting hook 220.

Preferably, the mounting seat 210 is welded and fixed to the edge-covering 110 (fig. 4) of the door leaf, and the mounting seat 210 is welded to the edge-covering of the door leaf through the first reinforcing stiffening plate, and meanwhile, the second reinforcing stiffening plate may be welded to a reinforcing mesh inside the door leaf firmly, the mounting threaded hole 211 is blocked with butter, and finally, the inside of the door leaf is poured with concrete, so that the mounting seat 210 and the door leaf 100 are defined as a whole. After the door leaf is poured, the door leaf hook 220 is installed on the installation seat through the bolt 310. If the door leaf lifting hook is damaged in the subsequent processing, installation and transportation processes, the bolt is directly unscrewed to replace the door leaf lifting hook. After the door leaf is installed, if the door leaf lifting hook easily collides with other objects, the door leaf lifting hook is directly disassembled, and the like, and the door leaf lifting hook is installed when needing to be used, so that the door leaf lifting hook is very convenient.

Example two

Referring to fig. 4 to 6, in order to weld the mounting seat 210 to the reinforcing mesh 120 inside the door leaf more firmly, the embodiment is further modified as follows:

the extension pipe 320 is welded at the bottom of the mounting seat 210, the extension pipe 320 is internally provided with a hollow extension screw hole 321, an inner thread is arranged on the inner wall of the extension screw hole 321, a welding disc 322 is arranged at one end, welded with the mounting seat 210, of the extension pipe 320, and the welding disc 322 is used for increasing the welding area with the mounting seat 210, so that the extension pipe 320 is more firmly fixed on the mounting seat 210.

The extension screw hole 321 is communicated with the installation screw hole 211, and the bolt 310 passes through the installation screw hole 211, enters the extension screw hole 321 and is respectively screwed and assembled with the extension screw hole 321 and the installation screw hole 211 through threads; the outside of the extension pipe 320 is sleeved and fixed with a welding ring 330, the welding ring 330 is fixed with a welding plate 331, and the welding plate 331 is welded and fixed with the reinforcing mesh 120. This kind of design on the one hand can greatly increased the fastness of mount pad, and on the other hand extension screw 321 is incomplete with the bolt assembly, and after the dismouting many times at the bolt, partial internal thread can produce wearing and tearing, influences the spiral close intensity of spiral, only needs to change the bolt a bit of length this moment for the bolt select into the internal thread of below can, thereby effectively increase the assembly strength of mount pad and door leaf lifting hook. In addition, the design prolongs the screwing length between the bolt and the door leaf, and also directly improves the assembly strength between the door leaf lifting hook and the door leaf.

Preferably, the extension screw hole 321 and the installation screw hole 211 are filled with grease 410 (lubricating grease), and the design can prevent sundries from entering or blocking the extension screw hole 321 and the installation screw hole 211 when the door leaf is poured, so that effective screwing of a subsequent bolt is ensured, internal threads can be protected, and corrosion is prevented.

More preferably, the bolt 310 is internally provided with an oil drain hole 311 penetrating along the axis thereof, and when the bolt is selected into the extension screw hole 321 and the installation screw hole 211 filled with grease, redundant lubricating oil can be discharged from the oil drain hole 311, so that the lubricating grease in the extension screw hole 321 and the installation screw hole 211 is prevented from generating high pressure to affect the stability of the mounting seat and the bolt.

More preferably, as the extension screw hole 321 and the mounting screw hole 211 are filled with grease, which cannot completely prevent sundries from entering the mounting screw hole 211, and the grease has viscosity, which easily absorbs the sundries at the outer end of the mounting screw hole 211, thereby affecting the screwing of the subsequent bolt. For this embodiment, a plugging hole 212 is formed in the outer end of the mounting threaded hole 211, a plugging component is mounted in the plugging hole 212, the plugging component includes a plugging slider 530, a plugging top cover 510, and a plugging slide 520, the plugging top cover 510 is mounted on the top of the plugging slide 520, a plugging slot 501 is formed between the plugging top cover 510 and the plugging slide 520, and the plugging slider 530 is engaged with and slidably mounted in the plugging slot 501; one end of the blocking slider 530 close to the axis of the blocking hole 212 is provided with a blocking inclined plane 533, and the end of the blocking slider 530 closes the top of the mounting threaded hole 211 to prevent foreign matters from entering the mounting threaded hole 211.

The plugging slider 530 has a plurality of plugging sliders 530, a belt groove 534 is respectively arranged at one end of each plugging slider 530 far away from the plugging inclined plane 533, an elastic ring 610 is arranged in the belt groove 534, the elastic ring 610 has high elasticity, and in an initial state, each plugging slider 530 is in a state shown in fig. 4, and at this time, the top of the installation threaded hole 211 is sealed.

When the bolt is not installed in the installation screw hole 211, the top of the installation screw hole 211 is closed by the blocking slider 530, thereby effectively preventing foreign materials from entering into the installation screw hole 211. When the bolt moves down, the tip of the bolt is engaged with the blocking inclined plane 533 to press the blocking slider 530, so that the blocking slider 530 overcomes the elastic force of the elastic ring 610 to move in the direction away from the axis of the mounting threaded hole 211 until the bolt passes through the blocking slider 530 and enters the mounting threaded hole 211. By adopting the design, foreign matters can be prevented from entering the mounting threaded hole 211, the bolt can be ensured to pass through the plugging sliding block 530, and after the bolt is pulled out of the plugging sliding block 530, the plugging sliding block 530 can automatically reset under the action of the elastic ring 610 to close the mounting threaded hole 211 again.

Preferably, the plugging top cover 510 is mounted on the mounting seat 210 by screws 340, so as to realize the assembly fixation of the whole plugging assembly with the plugging hole 212.

Preferably, the end surfaces of the blocking top cover 510 and the blocking slide seat 520 facing the blocking slot 501 are respectively provided with a blocking cover groove 511 and a blocking slide seat groove 521, the blocking cover groove 511 and the blocking slide seat groove 521 are respectively engaged with a first blocking guide block 531 and a second blocking guide block 532 and are assembled in a sliding manner, and the first blocking guide block 531 and the second blocking guide block 532 are respectively installed on the blocking slide block 530. This design can increase the stability of the plugging slider 530 when sliding radially along the plugging hole 212, thereby ensuring the movable closing of the plugging slider 530 to the mounting threaded hole 211. The bottom of the bolt 310 is provided with a bolt tip 312, and the bolt tip 312 can cooperate with the blocking inclined plane 533 to press the blocking slider 530.
