Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, a composite corrugated pipe includes a pipe body 1 and reinforcing blocks 2 sequentially arranged at intervals along an axial direction of the pipe body 1, where the reinforcing blocks 2 include first blocks 21 and second blocks 22 arranged at intervals, the first blocks 21 and the second blocks 22 are respectively sleeved on an outer periphery of the pipe body 1, a cross section of each first block 21 is square, and a cross section of each second block 22 is circular.

In the above embodiment, the first block 21 and the second block 22 of the reinforcing block 2 are made in different shapes, so that the corrugated pipe has corrugations with various shapes, thereby enabling the corrugated pipe to adapt to different use environments.

As shown in fig. 2, the corners of the first block 21 are provided with rounded corners 23, so as to prevent the corners of the first block 21 from scratching a user.

As shown in fig. 2, the composite corrugated pipe further comprises a reinforcing rib 3 arranged on the surface of the pipe body 1, one end of the reinforcing rib 3 is connected with the first block 21, and the other end of the reinforcing rib 3 is connected with the second block 22, so that the first block 21 and the second block 22 are prevented from deforming, and the compression resistance effect of the corrugated pipe is further improved.

As shown in fig. 3, the composite corrugated pipe further includes a first reinforcing rod 4, a second reinforcing rod 5 and a third reinforcing rod 6, one end of the first reinforcing rod 4 is connected with one end of the second reinforcing rod 5, the other end of the first reinforcing rod 4 is connected with one end of the third reinforcing rod 6, the other end of the second reinforcing rod 5 is connected with the other end of the third reinforcing rod 6, the joint of the first reinforcing rod 4 and the second reinforcing rod 5, the joint of the first reinforcing rod 4 and the third reinforcing rod 6 and the joint of the second reinforcing rod 5 and the third reinforcing rod 6 are respectively connected with the inner wall of the pipe body 1, and the pipe body 1 is prevented from deforming and collapsing by using the stability of the triangle, so as to improve the compression resistance effect of the composite corrugated pipe.

As shown in fig. 3, a polyurethane thermal insulation layer 7, a hot melt adhesive layer 8 and a flame retardant fiber cloth layer 9 are sequentially arranged on the inner wall of the pipe body 1 from outside to inside. The polyurethane heat insulation layer 7 is formed by laminating halogen-free flame-retardant thermoplastic polyurethane disclosed in the Chinese patent No. 201410470376.9, and has excellent flame-retardant and heat-insulating effects. The flame-retardant fiber cloth layer 9 is made of a flame-retardant glass fiber mesh cloth disclosed in the Chinese patent No. 200910178363.3, and has an excellent flame-retardant effect.

As shown in fig. 2 and 4, a first heat dissipation hole 24 penetrates through the first block 21 along the axial direction of the pipe 1, the pipe 1 is provided with a second heat dissipation hole 11, and the first heat dissipation hole 24 is communicated with the inside of the pipe 1 through the second heat dissipation hole 11. When the composite corrugated tube is used to protect the cable, the cable in the tube body 1 may generate heat, and thus it is necessary to dissipate the heat. The heat dissipation holes in the conventional design easily cause dust to enter the inside of the pipe body 1. Therefore, in the above embodiment, the second heat dissipating hole 11 of the tube 1 is communicated with the outside of the tube 1 through the transverse first heat dissipating hole 24, so as to effectively prevent dust from entering the inside of the tube 1.
