[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] The present invention provides a heat-resistant PVC cable pipe as Figures 1-4 shown, which includes a pipe body assembly 1. A reinforcing collar 2 is fixedly sleeved on the outer wall of the pipe body assembly 1. A connection assembly 3 is arranged on the outer wall of adjacent pipe body assemblies 1. The connection assembly 3 includes a first arc plate 31, a second arc plate 32, a fixed plate 33 and a locking housing 34. The bottom of the first arc plate 31 is rotatably connected to the bottom of the second arc plate 32. The first arc plate 31 and the second arc plate 32 are clamped between adjacent pipe body assemblies 1 through the reinforcing collar 2. Arc grooves of the reinforcing collar 2 are formed on the opposite sides of the first arc plate 31 and the second arc plate 32. Thus, the first arc plate 31 and the second arc plate 32 can be clamped and limited by the reinforcing collars 2 on the outer walls of each pipe body assembly 1, so as to butt-connect and install the two pipe body assemblies 1. The top of the first arc plate 31 and the top of the second arc plate 32 are respectively fixedly connected to the fixed plate 33. The locking housing 34 is clamped outside the corresponding fixed plate 33. A positioning rod 313 is fixedly connected to the top of the inner wall of the locking housing 34. A positioning groove 314 is formed on the top of the fixed plate 33. The outer wall of the positioning rod 313 is slidably sleeved in the positioning groove 314. The positioning rod 313 can improve the clamping stability of the locking housing 34 with the two fixed plates 33, so as to ensure the stability of the first arc plate 31 and the second arc plate 32 sleeved and locked at the connection of the two pipe body assemblies 1.

[0026] In particular, a connecting shaft 35 is rotatably connected inside the locking housing 34. A through hole is formed in the front surface of the fixing plate 33. The outer wall of the connecting shaft 35 is rotatably sleeved with the through hole. The end of the connecting shaft 35 is fixedly connected with a knob 36. A slot 38 is formed in the top of the fixing plate 33. Notches 37 are symmetrically formed in the outer wall of the connecting shaft 35. The notches 37 in the connecting shaft 35 are matched with the slot 38 on the fixing plate 33. Thus, when the notches 37 on the outer wall of the connecting shaft 35 are located at the top or bottom of the connecting shaft 35, the connecting shaft 35 will be clamped in the through hole of the fixing plate 33, and then the fixing plate 33 will be clamped and limited, so that the locking housing 34 is stably clamped on the outer wall of the fixing plate 33. When the notches 37 on the outer wall of the connecting shaft 35 are located on the side of the connecting shaft 35, the connecting shaft 35 can slide out of the slot 38 on the fixing plate 33 through the notches 37, so as to disassemble the locking housing 34. Then, the first arc plate 31 and the second arc plate 32 can be rotated and opened, so as to disassemble the corresponding connected pipe assembly 1.

[0027] Furthermore, a fixing block 39 is fixedly connected to the outer wall of the connecting shaft 35. Two limiting springs 310 are arranged on both sides of the fixing block 39. The two limiting springs 310 can give a elastic force to the fixing block 39 to keep the fixing block 39 in a vertical state, and then keep the connecting shaft 35 and the through hole on the fixing plate 33 in a stable clamping state. An arc rod 312 for guiding the limiting spring 310 is arranged inside the locking housing 34. A fixing rod 311 is fixedly connected inside the locking housing 34. The end of the arc rod 312 is fixedly connected with the fixing rod 311. The outer wall of the arc rod 312 is slidably sleeved with the limiting spring 310. A connecting groove matching with the arc rod 312 is formed in the top of the fixing block 39, and the center of the arc of the arc rod 312 is located at the bottom of the connecting shaft 35. Thus, when the connecting shaft 35 rotates by 90 degrees, the connecting shaft 35 can be separated from the fixing plate 33 through the notch 37. At this time, the connecting shaft 35 drives the fixing block 39 to rotate by 90 degrees. Since the fixing block 39 has a certain length, the fixing block 39 is still connected with the arc rod 312 at this time. When the connecting shaft 35 continues to rotate, the connecting groove on the fixing block 39 can be separated from the arc rod 312, which is convenient for its assembly or disassembly.

[0028] Specifically, the pipe assembly 1 includes a pipe base body 11, a heat insulation layer 12 and an anti-corrosion layer 13. The anti-corrosion layer 13 is fixedly sleeved on the outer wall of the pipe base body 11. The heat insulation layer 12 is fixedly sleeved inside the pipe base body 11. The heat insulation layer 12 is made of heat insulation materials, so as to improve the heat insulation performance of the pipe base body 11 again. The anti-corrosion layer 13 is made of a mixture of anti-corrosion and wear-resistant materials, so as to improve the anti-corrosion and wear-resistant performance of the pipe base body 11. The strengthening collar 2 is fixedly sleeved on the outside of the anti-corrosion layer 13.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features.
