Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Please refer to Figures 1 to 6 , the present utility model provides a technical solution: a BWFRP pipe connection mechanism, which includes a first connecting pipe 1 and a second connecting pipe 2. One end of the first connecting pipe 1 is fixedly installed with a first spherical cover 3, and one end of the second connecting pipe 2 is fixedly installed with a second spherical cover 4. The first spherical cover 3 is movably connected to the second spherical cover 4. A spherical outer cover 5 is fixedly installed on the outer side of the second connecting pipe 2. The first spherical cover 3 is movably connected to the spherical outer cover 5. An activity cavity 6 is provided between the outer side of the second spherical cover 4 and the inner side of the spherical outer cover 5. The first spherical cover 3 cooperates with the activity cavity 6. Sliding plates 7 are fixedly installed on both the top and bottom of the first spherical cover 3. Sliding grooves 8 are opened inside the top and bottom of the spherical outer cover 5. The sliding plates 7 are slidably connected to the sliding grooves 8. Through holes 9 are opened inside the sliding plates 7. Arc-shaped plates 10 are fixedly installed on both sides of the spherical outer cover 5 and located on both sides of the sliding grooves 8. A number of bolt holes 11 are opened inside the arc-shaped plates 10. The bolt holes 11 cooperate with the through holes 9. A first fixing bolt 12 is arranged inside the bolt holes 11, and the first fixing bolt 12 penetrates through the inside of the through holes 9.

[0022] The first connecting pipe 1 includes a first upper clamping pipe and a first lower clamping pipe. The second connecting pipe 2 includes a second upper clamping pipe and a second lower clamping pipe. The first spherical cover 3 includes a first upper cover and a first lower cover. The second spherical cover 4 includes a second upper cover and a second lower cover. The spherical outer cover 5 includes an upper outer cover and a lower outer cover. Connecting ears 15 are fixedly installed on both sides of the first upper clamping pipe, the first lower clamping pipe, the second upper clamping pipe, the second lower clamping pipe, the upper outer cover and the lower outer cover.

Arc-shaped clamping plates 13 are fixedly installed on the inner walls of the first connecting pipe 1 and the second connecting pipe 2.

Subsequently, adjust the rotation of the first connecting pipe 1 or the second connecting pipe 2 according to the bending angle of the cable and the pipe to make the first spherical cover 3 rotate in the movable cavity 6, so that it can be adjusted to the bending angle of the cable. After the adjustment is completed, clamp and connect the first connecting pipe 1 and the second connecting pipe 2 to two BWFRP pipes to be connected through the first upper clamping pipe, the first lower clamping pipe, the second upper clamping pipe and the second lower clamping pipe. After the connection is completed, install the second fixing bolts 16 on the connection ears 15 to connect and fix the two parts of the first connecting pipe 1, the second connecting pipe 2, the first spherical cover 3, the second spherical cover 4 and the spherical outer cover 5. Finally, pass the first fixing bolts 12 through the bolt holes 11 and the through holes 9 and fix them to fix the first spherical cover 3 at the adjusted angle, which is convenient and fast to use.
