[0002] Multiple cable protection tubes are connected by pipe joints. The pipe joints are in the shape of neck flanges made of polytetrafluoroethylene. When installing the pipe joints, holes need to be drilled on both the cable protection tube and the pipe joints, and then bolts are installed in the holes to fix the pipe joints and the cable protection tube together.

[0003] The cable protection tube needs to be buried underground, and the installation groove needs to be dug underground. The excavation length of the installation groove needs to be determined according to the installation requirements, and the length of each section of the cable protection tube is the same. When installing the cable protection tube, it is often encountered that the length of the cable protection tube cannot be divided by the length of the installation groove. Therefore, the operator needs to saw off the cable protection tube at the end to adapt to the length of the installation groove. The cut end of the protection tube also needs to be installed with a pipe joint. The cable protection tube is installed with a pipe joint before leaving the factory. There are production lines or auxiliary tools for quick installation, but the operating space is limited when installing it at the construction site. The operator needs to lift the end of the protection tube, and then the other operators will connect the pipe joint with the protection tube, and then perform the drilling operation.

[0004] This operation is labor-intensive, has low installation efficiency, and operators are unable to accurately locate the drilling positions. The operating space for drilling and installing bolts is also limited. Utility Model Content

[0016] like Figure 1-4The pipe joint fixing device for a cable protection pipe shown in the figure comprises a mounting plate 1 and a collar 5. The mounting plate 1 is in the shape of a circular ring. An embedded pipe 12 is fixedly mounted on the outer wall of one side of the mounting plate 1. Fixed shafts 2 are fixedly mounted on both sides of the mounting plate 1. Fitting plates 4 are arranged on both sides of the embedded pipe 12. The fitting plates 4 are rotatably connected to the fixed shaft 2. External threads are provided on the outer walls of the two fitting plates 4. Multiple matching rods 13 are fixedly mounted on the outer wall of the mounting plate 1 facing the embedded pipe 12. A rotating plate 3 is rotatably mounted on the outer wall of the fixed shaft 2. The end of the rotating plate 3 is fixedly connected to the fitting plate 4. An internal thread is provided on the inner wall of the collar 5. The internal thread of the collar 5 is adapted to the external thread of the outer walls of the two fitting plates 4. Multiple positioning holes 6 are provided on the outer wall of the collar 5.

[0017] The bonding plate 4 is an arc-shaped curved plate, and the curvature of the bonding plate 4 is in contact with the outer wall of the cable protection tube. The bonding plate 4 is vertically connected to the rotating plate 3.

[0018] Two fixing rings 7 are fixedly installed on the outer wall of the mounting plate 1 away from the embedded tube 12. The two fixing rings 7 are symmetrically arranged and installed below the outer wall of the mounting plate 1. A ground nail 8 is installed inside the fixing ring 7. The tip of the ground nail 8 faces downward, and the top of the ground nail 8 is an L-shaped bent rod. A fixing plate 9 is arranged between the two fixing rings 7. The fixing plate 9 is fixedly connected to the outer wall of the mounting plate 1. The outer wall of the fixing plate 9 is provided with a threaded hole, and a screw 10 is threadedly connected in the threaded hole. A bottom plate 11 is fixedly installed at the bottom of the screw 10, and the screw 10 is arranged parallel to the ground nail 8.

[0019] The operator first sets the collar 5 on the outside of the cable protection tube. The pipe joint is a plastic flange with a neck. The pipe joint is set on the outside of the embedded tube 12. The installation hole of the pipe joint is set on the matching rod 13, and the outer wall of the pipe joint is fitted with the outer wall of the installation plate 1. The operator drives the neck tube of the pipe joint to embed the installation plate 1 into the cable protection tube.
