[0029] In this embodiment, the two side edges of the through hole 4 are provided with chamfers, and the chamfers provided on the two side edges of the through hole 4 provide convenience for the composite cable body 1 to pass into the splicing shell 2, avoid the sharp edges of the through hole 4 from scratching the surface of the composite cable body 1, ensure the structural integrity of the composite cable body 1, and further improve the reliability of the splicing and assembly of the two composite cable bodies 1.

[0030] In this embodiment, one side of the rope head 5 is provided with two perforations 51, and one end of the composite cable body 1 is sequentially inserted through the two perforations 51, and the rope head 5 is fixedly pressed with the composite cable body 1. It needs to be pointed out that the operation steps of the rope head 5 fixedly pressed with the composite cable body 1 are as follows: first, the one end of the composite cable body 1 is sequentially inserted through the two perforations 51 on the rope head 5, and then the existing hydraulic machine and forming die are used to apply pressure to the rope head 5, so that the rope head 5 is plastically deformed under stress, that is, the rope head 5 is firmly fixed and pressed on one end of the composite cable body 1.

[0031] In this embodiment, it needs to be pointed out that the composite cable body 1 is composed of a nylon fiber layer, a polyester fiber layer, a steel wire layer, a polyester rope strand, a polyethylene rope strand, a carbon fiber rope core, an artificial fiber outer layer and an inner sheath, which has been disclosed and explained in the patent document of the splicing type composite cable with the authorization announcement number CN222043697U, so this paper will not make any superfluous repetition.

[0032] In this embodiment, the splicing shell 2, the annular plate 3, the locking bolt 31, the locking nut 32, the rope head 5, the limiting ring 6, the stop block 7 and the ball 52 can all be made of stainless steel, which has excellent corrosion resistance and high strength grade, and is suitable for humid and corrosive working environment.

[0033] Through the above structure, the operation principle of the splicing type composite cable provided by the present application is as follows:

[0034] When two composite cable bodies 1 need to be spliced, first, the ends of the two composite cable bodies 1 without the rope head 5 are respectively inserted into the corresponding splicing shell 2 and pass through the through hole 4 on the splicing shell 2, that is, the end of the composite cable body 1 with the rope head 5 is pulled into the splicing shell 2 and abuts against the limiting ring 6. Because the two side edges of the through hole 4 are provided with chamfers, the cable can be guided to pass through smoothly, and the jamming and scratching can also be avoided.

[0035] Then, one side of the stop block 7 is inserted into one of the splicing shells 2 and abuts against the composite cable body 1 inside it, and then the two splicing shells 2 are moved close to each other, so that one end of the stop block 7 is gradually inserted into the other splicing shell 2 until it abuts against the composite cable body 1 inside it, so as to preliminarily fix the positions of the two rope heads 5 and prevent them from excessive displacement.

[0036] Then, the two annular plates 3 on the outer walls of the spliced shell 2 are aligned, a plurality of bolt holes corresponding to each other are formed on the two annular plates 3, a plurality of locking bolts 31 are sequentially inserted into the bolt holes, locking nuts 32 are threadedly installed on the locking bolts 31, the two annular plates 3 are tightly connected by tightening the locking nuts 32, and thus the splicing and fixing of the two composite cable bodies 1 are completed.

[0037] During use after splicing, when the composite cable body 1 needs to be rotated under the action of an external force, the plurality of uniformly distributed rolling balls 52 embedded on the outer circular wall of the rope head 5 play a key role. The rolling balls 52 are in sliding contact with the inner wall of the spliced shell 2. Due to the rolling characteristics of the rolling balls 52, when the external force causes the composite cable body 1 to rotate, the rolling balls 52 can smoothly slide on the inner wall of the spliced shell 2, greatly reducing the rotation resistance, so that the two spliced composite cable bodies 1 can be flexibly rotated to adapt to different direction pulling and twisting requirements. In addition, the outer surfaces of the limiting stop ring 6, the rope head 5 and the stop block 7 are designed as smooth surface structures. When the two spliced composite cable bodies 1 are in use, the smooth surfaces can reduce the contact area and friction between the components, avoid excessive heat and component wear caused by friction, thereby prolonging the service life of the components, reducing energy loss, improving the working efficiency of the two spliced composite cable bodies 1, and improving the stability and reliability of the splicing and fixing.
