As shown in fig. 1-6, the present application provides:

an oblate spiral watertight air pipe capable of preventing secondary deformation comprises a pipe body 1, an anti-deformation mechanism 2 and a connecting mechanism 3; the anti-deformation mechanism 2 is arranged on the pipe body 1, and the anti-deformation mechanism 2 comprises a central shaft 2a, a supporting component 2b, a screw component 2c, a first fixing component 2d and a first fixing plate 2 e; the central shaft 2a is arranged in the pipe body 1 along the length direction of the pipe body 1; the spiral piece 2c is arranged on the periphery of the central shaft 2a along the axis of the central shaft 2a, the spiral piece 2c is in threaded fit with the inner wall of the pipe body 1, and a first gap is reserved between the spiral piece 2c and the central shaft 2 a; the support member 2b is disposed in the first gap; a first fixing member 2d is provided on one end of the center shaft 2 a; the first fixing plate 2e is fixedly disposed at an end of the pipe body 1 close to the first fixing member 2 d.

Based on the above embodiment, the technical problem that this application wants to solve is how under the prerequisite of guaranteeing oblate spiral watertight tuber pipe performance, can also strengthen oblate spiral watertight tuber pipe's intensity. For this reason, this application coupling mechanism 3 sets up respectively at the both ends of body 1, because body 1 is the multistage formula, so when the installation, need install multistage body 1 combination together, can link together two body 1 of difference through the coupling mechanism 3 that sets up on body 1. Thereby realizing the technical requirements for the installation of the multi-section pipe body 1. The theory of operation of anti-deformation mechanism 2 is as follows, body 1 is oblate spiral tubular structure, body 1's outside is arranged in to center pin 2a when not yet installing, when needs are installed, only need to aim at center pin 2a and body 1's one end, rotate center pin 2a afterwards, because be connected through supporting component 2b between center pin 2a and the spiral 2c, like this when center pin 2a is rotatory, spiral 2c just can drive spiral 2c under supporting component 2 b's drive and rotate this moment, spiral 2c is helical structure, and body 1 also is helical structure. The external radius of screw 2c is the same with the minor axis length of body 1 inner wall, and screw 2c alright carry out screw-thread fit with the inner wall of body 1 like this, and after screwing in the inside of body 1 with center pin 2a and screw 2c completely, the terminal surface of the one end that first fixed subassembly 2d was kept away from to center pin 2a this moment and body 1 keep away from the terminal surface coplane of the one end of first fixed subassembly 2 d.
