Problems solved by technology

[0005] First: When placing cables inside the bellows: the cables cannot be placed in groups, resulting in the messy placement of the wiring harness inside the bellows, which is not convenient for later maintenance;
[0006] Second: When the cable is placed inside the corrugated tube, the cable can only be installed by threading. The length of the corrugated tube is relatively long, which is very inconvenient when placing the cable

specific Embodiment approach 1

[0038] Specific implementation mode one: please refer to Figure 1-8 , the present invention provides a technical solution: a non-cracking high-strength double-wall corrugated pipe, comprising: a corrugated pipe body 3, a clamping structure 4 and a connecting structure 5;

[0039] The outer side of the bellows body 3 is evenly installed with multiple sets of outer reinforcing bushings 2, and the distance between two adjacent sets of outer reinforcing bushings 2 is the same, while the outer side of the outer reinforcing bushings 2 is wrapped with reinforced armor 1, and the bellows The inside of the body 3 is provided with a placement cavity 34, and the interior of the placement cavity 34 is provided with a clamping structure 4;

[0040]The clamping structure 4 is a detachable structure inside the bellows body 3, and the clamping structure 4 is composed of four parts: the first clamping block 41, the second clamping block 42, the third clamping block 43 and the fourth clamping ...

specific Embodiment approach 2

[0044] Embodiment 2: This embodiment is a further limitation of Embodiment 1. The cross-sections of reinforced armor 1, outer reinforced bushing 2 and bellows body 3 are concentric circle structures, and reinforced armor 1 and outer reinforced bushing 2 are combined in Together they constitute the outer reinforcement structure of the bellows body 3 .

[0045] Such as Figure 1-2 As shown: the reinforcement armor 1 and the outer reinforcement bushing 2 form the reinforcement structure of the bellows body 3, and the reinforcement armor 1 covers the outside of the bellows body 3, which can avoid direct irradiation of strong ultraviolet rays on the outer surface of the bellows body 3, Avoid surface cracking of the bellows body 3 .

specific Embodiment approach 3

[0046] Embodiment 3: This embodiment is a further limitation of Embodiment 2. The outer reinforcing bush 2 includes an outer casing 21, an inner cavity 22 and reinforcing ribs 23, and the outer casing 21 covers the outer side of the bellows body 3, while the inside of the outer casing 21 An inner cavity 22 is provided, and a plurality of sets of reinforcing ribs 23 are evenly and fixedly arranged in the inner cavity 22, and the reinforcing ribs 23 are arranged in an "X" shape.

[0047] Such as figure 1 and Figure 6 As shown: there are multiple groups of reinforcing ribs 23 evenly fixed inside the jacket 21. When the surface of the jacket 21 resists compression, the pressure acts on the surface of the reinforcing ribs 23, and the reinforcing ribs 23 resist this pressure, so that the corrugated pipe body 3 for anti-pressure protection.

Abstract

The invention discloses a non-cracking high-strength double-wall corrugated pipe which comprises a corrugated pipe body, multiple sets of outer reinforcing bushings are evenly installed on the outer side of the corrugated pipe body, the distance between every two adjacent sets of outer reinforcing bushings is consistent, meanwhile, the outer sides of the outer reinforcing bushings are wrapped with reinforcing armors, and a containing cavity is formed in the corrugated pipe body; a wire clamping structure is arranged in the placement cavity; the wire clamping structure is of a detachable structure in the corrugated pipe body, and the wire clamping structure is composed of a first clamping block, a second clamping block, a third clamping block and a fourth clamping block. According to the non-cracking high-strength double-wall corrugated pipe and the wire clamping structure, an original threading mode of a cable can be changed into a wire clamping mode, the cable can be installed more rapidly and simply, the time for installing the cable is shortened, the cable is arranged in the second wire clamping groove and the third wire clamping groove in a clamping mode, and therefore the cable can be installed more conveniently and rapidly. And clamping is carried out through the second positioning strip and the second positioning groove.

Description

technical field [0001] The invention relates to the field of bellows, in particular to a non-cracking high-strength double-wall bellows. Background technique [0002] Double-wall corrugated pipes are used in the discharge and recovery of urban sewage and rainwater, laying of power cables, etc., and have the characteristics of light weight, high pressure resistance, long life and low cost. [0003] Existing corrugated pipes are of solid-wall structure, with insufficient load resistance against external pressure, and are easily deformed, damaged, and easily worn. When in contact with hard media, the pipes may crack and deform. The device and the protective device cannot be effectively adjusted for bellows of different diameters, and do not have effective adjustment. The existing bellows are time-consuming and labor-intensive in connection, which affects the construction period, and the connection is not strong enough. [0004] In order to solve the above problems, after searc...
