[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of the present utility model and its application or use. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figures 1-5 Shown, the embodiment of the present utility model provides a civil air defense air duct structure.

The connecting device 2 is located at one end of the air duct main body 1; the connecting device 2 includes a positioning component 21 for aligning and positioning with another civil air defense air duct structure and a locking component 22 for fixing with another civil air defense air duct structure. The locking component 22 is connected to the air duct main body, and the positioning component 21 is installed at one end of the locking component 22.

[0026] When the air defense duct structure is in normal use, the duct body 1 of another air defense duct structure is placed on the positioning component 21 for positioning. After positioning, the other air defense duct structure is pushed backward so that the duct bodies 1 of the two ducts are closely attached. The locking component 22 is used to lock the duct body 1 and the duct body 1 of another air defense duct structure. Through the settings of the positioning component 21 and the locking component 22, when connecting adjacent air defense duct structures, the two air defense duct structures can be positioned by aligning the positioning component 21. After positioning, they can be locked by the locking component 22. The above settings make it unnecessary to perform additional positioning operations during installation and do not require connection through external connectors such as flanges, making the installation simple and convenient.

[0027] Specifically, the duct body 1 includes a pipe body 11, a plurality of bumps 12, a connecting ring 13 and a sealing ring 14. The plurality of bumps 12 are fixedly installed at intervals along the circumferential direction of the pipe body 11 on the outer side of the rear end of the pipe body 11. The connecting ring 13 is fixedly installed at the front end of the pipe body 11. The sealing ring 14 is fixedly installed at the rear end of the pipe body 11. The front end of the connecting ring 13 is connected to the locking component 22. Each bump 12 extends along the axial direction of the pipe body 11.

[0028] The front end of the connecting ring 13 is provided with a first annular groove for fitting and accommodating the pipe body 11 of another air defense duct structure. A plurality of first through grooves for slidingly fitting with the plurality of bumps 12 of another air defense duct structure are provided on the inner side wall of the first annular groove. When the two air defense duct structures are connected to each other, the rear end of one pipe body 11 is inserted into the front end of the other pipe body 11, and the bumps 12 and the first through grooves are in one-to-one snap-fit. With such a setting, the connecting ring 13 and another air defense duct structure can be rotationally stopped in the circumferential direction. Moreover, the bottom wall of the first annular groove is used for limiting cooperation with the end of the pipe body 11 of another air defense duct structure to limit the moving stroke of another air defense duct structure towards the rear end of the pipe body 11.

[0029] In the embodiment of this solution, the positioning component 21 includes a positioning plate 211 and a positioning sliding ring 212. The positioning plate 211 is fixedly installed at the front end of the positioning sliding ring 212. The rear end of the positioning sliding ring 212 is connected to the locking component 22.

[0030] The positioning plate 211 is a semi-circular plate. A second through groove for slidingly fitting with the bump 12 of another air defense duct structure is provided on the inner side wall of the positioning plate 211. A plurality of third through grooves for slidingly fitting with the bump 12 of another air defense duct structure are provided inside the positioning sliding ring 212. The second through groove and the third through groove are communicated with each other.

[0031] The locking assembly 22 includes a connecting shell 221, a locking slip ring 222, a hollow worm gear 223, a worm 224 and a handle 225. The inner side of the connecting shell 221 is fixedly connected to the positioning slip ring 212 and the connecting ring 13 respectively. The locking slip ring 222, the hollow worm gear 223 and the worm 224 are located on the inner side of the connecting shell 221. The front end of the locking slip ring 222 is rotatably connected to the positioning slip ring 212, and the rear end of the locking slip ring 222 is rotatably connected to the connecting ring 13. A fourth through groove is provided on the inner side of the locking slip ring 222 for cooperating with the protrusion 12 of another human air-defense duct structure. The hollow worm gear 223 is fixedly installed on the outer side of the locking slip ring 222. The hollow worm gear 223 is meshed with the worm 224. The worm 224 is rotatably installed on the inner side of the connecting shell 221. The lower end of the handle 225 is fixedly connected to one end of the worm 224. The locking slip ring 222 rotates to connect or disconnect the first through groove and the third through groove through the fourth through groove.

[0032] A second annular groove for accommodating the hollow worm gear 223 is provided on the inner side of the connecting shell 221 , and a fifth through groove for accommodating the worm 224 is provided on one side of the connecting shell 221 . The connecting shell 221 is fixedly connected to the connecting ring 13 by bolts.

[0033] Two transparent windows are provided on the connecting shell 221, which are respectively located near the handle 225 and directly below the connecting shell 221. A scale mark is provided on the outside of the locking slip ring 222, and the position of the scale mark corresponds to the fourth through groove on the inside of the locking slip ring 222.

[0034] When the air-defense duct structure is in normal use, the tube body 11 of another air-defense duct structure is placed on the positioning plate 211 and positioned through the lower protrusion 12, and the other air-defense duct structure is pushed backward so that the sealing ring 14 of the other air-defense duct structure is in close contact with the inner side of the connecting ring 13; turn the handle 225, the handle 225 drives the worm 224 to rotate, the worm 224 drives the hollow worm gear 223 to rotate, and the hollow worm gear 223 drives the locking slip ring 222 to slide along the positioning slip ring 212, and the locking slip ring 222 moves to the front of the protrusion 12 of the other air-defense duct structure at the part without a through groove on the inner side; the locking slip ring 222 is pressed against the other air-defense duct structure The protrusion 12 of the air duct structure is blocked, and the protrusion 12 of another air duct structure can be quickly locked by setting the locking slip ring 222; it makes installation simple and quick, and self-locking is achieved by setting the hollow worm gear 223 and the worm 224, so as to prevent the locking slip ring 222 from rotating itself and causing the protrusion 12 of another air duct structure to be disengaged. By setting the transparent window of the connecting shell 221 and the mark of the locking slip ring 222, it is possible to quickly observe whether the locking slip ring 222 has completed locking the protrusion 12 of another air duct structure during installation and inspection, thereby further avoiding the situation of disengagement.
