DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-Figure 3A rust-proof steel belt strong skeleton polyethylene spiral corrugated pipe, comprising a corrugated pipe 1, a fixed shell 2 is arranged on the outside of the corrugated pipe 1, a connecting block 6 is fixedly connected to the inner wall of the fixed shell 2, and the connecting block 6 is fixedly connected to the outside of the corrugated pipe 1, and sliding grooves 7 are provided on both sides of the fixed shell 2, and an extension shell 3 is slidably connected between the inner walls of each sliding groove 7, and each extension shell 3 is extended to the outside of the fixed shell 2, and a connecting spring 8 is fixedly connected to the side wall of each extension shell 3, and one end of each connection spring 8 away from the extension shell 3 is respectively fixedly connected to the inner wall of the corresponding sliding groove 7, and a fixed structure is arranged on each extension shell 3, and the extension shell 3 can move outward, thereby increasing the distance covered by the fixed shell 2 and the extension shell 3 The corrugated pipe 1 is protected, and the corrugated pipe 1 that needs to be protected is protected;

[0019] The fixing structure includes a connecting groove 9 provided on the outside of the fixing block 12, each connecting groove 9 is slidably connected with a connecting plate 10, one end of each connecting plate 10 away from the bellows 1 is fixedly connected with the fixing block 12, one end of each connecting plate 10 away from the corresponding fixing block 12 is fixedly connected with an adjusting spring 11, and one end of each adjusting spring 11 away from the connecting plate 10 is respectively fixedly connected to the inner wall of the connecting groove 9, and a plurality of groups of fixing grooves 13 are provided on the fixing shell 2, each group of fixing grooves 13 respectively corresponds to a fixing block 12, so that the extension shell 3 moves outward, and when the extension shell 3 moves to the fixing groove 13 where the fixing block 12 is located on the outside, the elastic force of the adjusting spring 11 causes the connecting plate 10 and the fixing block 12 to move upward, so that the fixing block 12 is inserted into the fixing groove 13, and the extension shell 3 is fixed;

[0020] An extrusion block 14 is slidably connected between the inner walls of each fixed slot 13, and an adjusting rod 4 is fixedly connected to the top of each extrusion block 14. Each adjusting rod 4 passes through the upper inner wall of the corresponding fixed slot 13 and extends to the outside of the fixed shell 2. The adjusting rods 4 corresponding to the same group of fixed slots 13 are fixedly connected to a pressing block 5 at one end located on the outside of the fixed shell 2. Pressing the pressing block 5 moves the corresponding adjusting rod 4 and the extrusion block 14 accordingly, pushes the fixed card block 12 out of the fixed slot 13 and returns to the connecting slot 9. At this time, the extension shell 3 can be moved to the outside to increase the protection range of the extension shell 3. The outside of each pressing block 5 is wrapped with a protective cover.

[0021] The surface of the bellows 1 is covered with a reinforcement layer to improve the strength of the bellows 1; the outer sides of the fixed shell 2 and the extended shell 3 are wrapped with a rust-proof steel layer to prevent the fixed shell 2 and the extended shell 3 from rusting and being damaged.

[0022] When the extension shell 3 moves to the outside, the elastic force of the connecting spring 11 causes the connecting plate 10 and the fixing block 12 to move upward, so that the fixing block 12 is inserted into the fixing slot 13 to fix the extension shell 3, thereby increasing the distance between the fixing shell 2 and the extension shell 3 covering the corrugated pipe 1, and protecting the corrugated pipe 1 that needs to be protected. When the extension shell 3 moves to the outside, the connecting spring 8 is stretched and deformed. After the pressing block 5 is pressed to make the fixing block 12 out of the fixing slot 13, the elastic force of the connecting spring 8 causes the extension shell 3 to move back and return to the sliding slot 7.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
