Detailed Description

The invention is further described with reference to the following specific drawings and examples.

Example 1

As shown in fig. 1 to 4, embodiment 1 discloses an anti-reverse-folding protective sleeve, which comprises a flexible outer pipe 1, a flexible inner pipe 2 and an elastic anti-reverse-folding pipe fitting 3, wherein the flexible outer pipe 1 is sleeved outside the flexible inner pipe 2, two ends of the flexible outer pipe 1 are hermetically connected with two ends of the flexible inner pipe 2, and the hardness of the flexible outer pipe 1 is greater than that of the flexible inner pipe 2; the elasticity prevents that the activity of turn over pipe fitting 3 sets up between flexible outer tube 1 and flexible inner tube 2, and elasticity prevents that 3 both ends of turn over pipe fitting and flexible outer tube 1 and the 2 both ends butt of flexible inner tube.

In the concrete application, when preventing turning over the protective sheath and receive the effort of buckling, because the hardness of flexible inner tube 2 is less than flexible outer tube 1, flexible inner tube 2 is at first buckled, this moment because the activity of the anti-pipe fitting of turning over 3 of elasticity sets up between flexible outer tube 1 and flexible inner tube 2, it is not fixed connection between the anti-pipe fitting of turning over 3 of elasticity and the flexible inner tube 2 promptly, the anti-pipe fitting of turning over 3 of turning over is prevented to elasticity just can not be completely along with the buckling of flexible inner tube 2 like this, the anti-pipe fitting of turning over 3 of elasticity just plays the effect of a bracing piece at flexible outer tube 1 and flexible inner tube 2 like this, can reduce the range of buckling of flexible inner tube 2, thereby reduce the.
