DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-6 The utility model provides a technical solution: a glass fiber reinforced plastic pipe which is easy to install and dock, comprising a docking tube 1, a glass fiber reinforced plastic pipe body 2, a sealing ring 3, a lower connecting splint 4, an upper connecting splint 5, a fixed connecting rod 6, a fixed connecting cap 7, an auxiliary block 8, a docking mechanism 9, a movable connecting column 10, a pull rod 11, a baffle 12, a mounting column 13 and a notch 14.

[0030] When using this easy-to-install fiberglass pipe, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the butt-jointed tube 1 is butt-jointed, firstly, the lower connecting splint 4 and the upper connecting splint 5 are respectively engaged at the upper and lower ends of the butt-jointed tube 1, and then the fixed connecting rod 6 is respectively inserted into the front and rear ends of the lower connecting splint 4, and the fixed connecting rod 6 is connected through the upper connecting splint 5, and then the fixed connecting cap 7 threadedly connected to the upper end of the fixed connecting rod 6 is rotated so that the fixed connecting cap 7 is tightly fitted to the upper end of the upper connecting splint 5, thereby facilitating the fixing of the lower connecting splint 4 and the upper connecting splint 5 on the outer side of the butt-jointed tube 1, and the FRP pipe body 2 is respectively inserted into the left and right ends of the butt-jointed tube 1, and a sealing ring 3 is provided at the connection between the butt-jointed tube 1 and the FRP pipe body 2, and the sealing effect of the connection between the butt-jointed tube 1 and the FRP pipe body 2 is improved by the setting of the sealing ring 3;

[0031] like Figure 5 and Figure 6As shown, the upper and lower ends of the docking tube 1 are symmetrically provided with docking mechanisms 9, and the docking mechanism 9 includes a movable connecting column 10 rotatably connected to the middle of the auxiliary block 8, a pull rod 11 fixedly connected to the middle of the movable connecting column 10, a baffle 12 for limiting, a mounting column 13 fixedly connected to the upper end of the upper connecting clamp 5, and a notch 14 opened on the side of the mounting column 13. By rotating the pull rod 11 to 90°, the pull rod 11 drives the movable connecting column 10 to rotate in the middle of the auxiliary block 8, and the torsion spring at the connection between the movable connecting column 10 and the auxiliary block 8 undergoes elastic deformation. At this time, the movable connecting column 10 drives the baffle 12 to rotate, and then the FRP pipe body 2 is inserted into the middle of the docking tube 1, while the movable connecting column 10 is inserted into the mounting column 13, and the baffle 12 passes through the mounting column 13 through the notch 14;

[0032] When the FRP pipe body 2 is fully inserted into the left and right sides of the docking tube 1, the pull rod 11 is released, and the torsion spring at the connection between the movable connecting column 10 and the auxiliary block 8 restores its elastic deformation, driving the movable connecting column 10 and the auxiliary block 8 to rotate. At this time, the movable connecting column 10 drives the baffle 12 to rotate, so that the baffle 12 and the mounting column 13 are in a close fit, as shown in FIG. Figure 6 The state shown makes it easy to quickly connect and position the butt sleeve 1 and the FRP pipe body 2.
