[0008] Preferably, the pipe positioning assembly includes a plurality of connecting seats, which are evenly distributed on the inner side of the semi-circular frame, and both ends of the connecting seats are fixed to the inner side of the semi-circular frame by fixing screws.

[0009] Preferably, each of the connecting seats is threaded with two adjusting screws. The end of each adjusting screw located on the outside of the semi-annular frame is fixed with a handle, and the end of each adjusting screw located on the inside of the semi-annular frame is provided with an integral protrusion.

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] Please refer to the appendix. Figures 1-4The ultra-lightweight external connector provided by this utility model includes two semi-circular frames 1. Both ends of the semi-circular frames 1 are provided with insertion holes 2. The insertion holes 2 on the two semi-circular frames 1 are all penetrated by pins 3. That is, the two semi-circular frames 1 can be fixed by insertion of pins 3, which makes it convenient to install from the outside of the pipe and convenient to disassemble and remove from the outside of the pipe. Several pipe positioning components can be detached from the inside of the semi-circular frames 1. Lifting components can also be detached and installed on the outside of the semi-circular frames 1. Reinforcing components can also be detached and installed on the semi-circular frames 1.

[0021] The pipe positioning assembly includes several connecting seats 4, which are evenly distributed inside the semi-annular frame 1. Both ends of the connecting seats 4 are fixed to the inside of the semi-annular frame 1 by fixing screws 5, which makes the connecting seats 4 easy to disassemble and assemble. The connecting seats 4 can also serve to connect the semi-annular frame 1. Each connecting seat 4 is threaded with two adjusting screws 6. The end of the adjusting screw 6 located outside the semi-annular frame 1 is fixed with a handle 7. The end of the adjusting screw 6 located inside the semi-annular frame 1 is provided with an integrated protrusion 8. Specifically, the operator can control the protrusion 8 to move linearly back and forth by rotating the adjusting screw 6 in the forward and reverse directions through the handle 7.

[0022] The pipe positioning assembly also includes several positioning blocks 9, each with a threaded groove 10 on its surface. Several protrusions 8 are threadedly connected to the threaded grooves 10. Specifically, the operator can rotate the adjusting screw 6 by the handle 7 to control the protrusions 8 to drive the positioning blocks 9 to move linearly, so that they can be evenly abutted from all sides of the pipe, thus achieving the function of assisting the pipe to quickly connect. The positioning blocks 9 are easy to disassemble and install, making it easy to replace them after wear.

[0023] The hoisting assembly includes several threaded holes 11, which are evenly distributed on the semi-annular frame 1. Each threaded hole 11 is threaded with a hoisting bolt 12. Specifically, the hoisting bolt 12 facilitates the hoisting of the semi-annular frame 1, and the hoisting bolt 12 is easy to install and remove.

[0024] The reinforcing component includes several reinforcing rods 13, which are evenly inserted through the semi-annular frame 1. Both ends of the reinforcing rods 13 are threaded with nuts 14, which abut against the outer surface of the semi-annular frame 1. Specifically, under the action of the reinforcing rods 13 and nuts 14, they can not only connect the semi-annular frame 1, but also effectively strengthen the semi-annular frame 1.

[0025] In summary, this utility model not only has the function of assisting pipe connection, but also has a simple overall structure, is easy to disassemble and assemble, and is easy to carry. Furthermore, the pipe positioning component used to abut the pipe is easy to disassemble and assemble, making it easy to replace after wear, thus better meeting the needs of use.

[0026] The usage process of this utility model is as follows: Before installing the external connector on the pipeline, the operator removes the anti-corrosion layer, rust and other foreign objects from the surface of the pipeline connector. Then, the two semi-circular frames 1 are placed on the outside of the pipeline and the pins 3 are installed. Then, the extension length of the adjusting screw 6 is adjusted by turning the handle 7 to ensure that it is consistent with the gap with the pipeline. Then, the positioning blocks 9 are symmetrically tightened. After spot welding, the pins 3 are removed, the connector is disassembled into two parts and removed from both sides of the pipeline. After each use, the product is cleaned, the threads are cleaned, and it is stored in a dry place to avoid moisture and water.

[0027] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
