[0023] Example:

[0024] Figure 1 It is a spliced ​​coupling that is easy to maintain. Figure 2 This is a schematic diagram of the welding connection between the connecting tube and the body. Figure 3 yes Figure 1 The partially enlarged schematic diagram includes two half-couplings 1 and an intermediate piece 2 , wherein the two half-couplings 1 are connected to both ends of the intermediate piece 2 , respectively.

[0025] The half coupling 1 includes a connecting cylinder 11 and a body 19 . The connecting cylinder 11 and the body 19 are spliced ​​together by a weld 18 . The spliced ​​structure is easy to process and produce.

[0026] The outer wall of the connecting tube 11 is provided with at least one slit 12 along the axis, so that the outer end of the connecting tube (the left end in the figure) is formed into two semicircular structures. When the two semicircles are tightened and squeezed by the main fastening bolts 16, they approach each other and squeeze the main shaft (not shown), thereby becoming tighter and tighter, and the connection between the main shaft and the main shaft is stable.

[0027] There are two slits 12, which are symmetrical around the circumference to prevent weight imbalance. The outer ends of the slits 12 are open, and the inner ends are arcuate walls 13, which are located at the center of the connecting tube 11. The outer ends are open for easy contraction, while the inner ends are arcuate for easy extrusion.

[0028] The first surface of the gap 12 is provided with an embedding block 14, and the second surface is provided with an embedding groove 15, and the embedding block 14 can extend into the embedding groove 15; when the gap is squeezed, the two semicircles approach each other, and the embedding block 14 gradually approaches the embedding groove 15 and extends into the embedding groove 15, further increasing stability.

[0029] The embedding block 14 is a wedge-shaped block, and the small acute angle end of the wedge-shaped block is located at the arc wall 13 and the large acute angle end is close to the opening of the gap 12 ; the shape of the embedding groove 15 matches the embedding block 14 .

[0030] The outer wall of the connecting tube 11 is also threadedly connected to a primary fastening bolt 16 and a secondary fastening bolt 17. The primary fastening bolt 16 is used for primary fastening, while the secondary fastening bolt 17 is used for auxiliary fastening. Both the primary fastening bolt 16 and the secondary fastening bolt 17 are sleeved onto the connecting tube 11 and screwed close to the main body 19 when not in use.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
