[0036] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0037] The utility model is a novel rope winding shaft 1 system, such as Figure 1-14As shown, it includes a winding shaft 1 and a rope object 2; the winding shaft 1 includes a shaft body 11 for winding the rope object 2, and one side of the shaft body 11 has a connecting hole 12 for connecting the rope object 2; the connecting hole 12 includes a hole monomer 121 and a hole monomer 2 122 extending in the same direction; the rope object 2 has a rope connecting segment connected to the connecting hole 12, the rope connecting segment includes a first rope segment 21 passing through the hole monomer 1 121, a second rope segment 22 passing through the hole monomer 2 122 after being bent, and a third rope segment 23 outside the hole monomer 121 and the hole monomer 2 122 after being bent. During the actual assembly process of the utility model, the connecting section of the rope object 2 can be passed through the hole monomer one 121 to form the first rope section 21, and after being bent, it can be passed through the hole monomer two 122 to form the second rope section 22, and a third rope section 23 that is bent and located outside the hole monomer one 121 and the hole monomer two 122 is left. The first rope section 21, the second rope section 22 and the third rope section 23 are bent at least twice to form a friction contact structure equivalent to a knotted and tied structure at the connecting hole 12 of the winding shaft 1, which can withstand a certain pulling force and will not fall out of the connecting hole 12. In particular, when the rope object 2 is a steel wire rope, based on the hardness of the steel wire rope and the friction force generated by the stress concentration at the bending point and the lever bending resistance of the three rope sections in different directions at the bending point, even if the far end of the steel wire rope is subjected to a large pulling force, the connecting section of the steel wire rope will be stuck in the connecting hole 12 and will not fall off. Furthermore, it also includes a bending portion formed by the bending between any two of the first rope segment 21, the second rope segment 22 and the third rope segment 23; the bending portion includes a first bending portion 24 and a second bending portion 25 at different bending positions. The bending portion is a structure for the first rope segment 21, the second rope segment 22 and the third rope segment 23 to achieve bending, and can be formed by bending the ends of the entire rope object 2 to adapt to the hole monomer 1 121 and the hole monomer 2 122. Each bending portion corresponds to the hole edge of the hole monomer 1 121 and the hole monomer 2 122 and forms a friction contact structure equivalent to knotting and tying here, which can withstand a certain tension and will not fall out of the connection hole 12. In particular, when the rope object 2 is a steel wire rope, based on the hardness of the steel wire rope and the friction force generated by the stress concentration at the bending position and the lever bending resistance in different directions generated by the three rope segments at the bending position, even if the far end of the steel wire rope is subjected to a large tension, the rope connecting section of the steel wire rope will be stuck at the connection hole 12 and will not fall off. Each bending portion can resist a certain proportion of the pulling force on the rope 2. After two bending portions, the rope 2 can be locked on the winding shaft 1 by utilizing its own rigidity. The steel wire rope or one-piece resin rope (non-flexible) has a more obvious locking force.In order to further facilitate the perforated and bent connection between the rope 2 and the shaft body 11, the hole monomer 121 has a port A1211 facing one end and a port B1212 facing the other end, and the hole monomer 2 122 has a port C1221 corresponding to the port A1211 and a port D1222 corresponding to the port B1212 and at the same end; the rope connecting section is at the rope head of the rope 2; based on the extension direction of the rope 2, the first rope segment 21 has a rope segment end a farther away from the rope head end and a rope segment end b closer to the rope head end, the second rope segment 22 has a rope segment end c farther away from the rope head end and a rope segment end d closer to the rope head end, and the third rope segment 23 has a rope segment end e farther away from the rope head end and a rope segment end f closer to the rope head end; the first rope segment 21 is farther away from the end of the rope head than the second rope segment 22 and the third rope segment 23. The first rope segment 21, the second rope segment 22 and the third rope segment 23 can be specifically located on a whole rope object 2. The winding shaft 1 also includes an upper shaft wall located above the shaft body 11 and a lower shaft wall located below the shaft body 11, and a winding groove for winding the rope object 2 and limiting the position is formed between the upper shaft wall and the lower shaft wall. The specific structure can be that the end edges of the hole monomer 121 and the hole monomer 2 122 are chamfered, and there is a ridge between the two to ensure the strength of the hole monomer 121 and the hole monomer 2 122.

[0038] A preferred embodiment thereof is as follows Figure 2-5As shown, the second rope segment 22 is between the first rope segment 21 and the third rope segment 23; the first bending portion 24 is between the first rope segment 21 and the second rope segment 22, and the second bending portion 25 is between the second rope segment 22 and the third rope segment 23; the rope segment end a is at the same end as the port A1211, and the rope segment end b is at the same end as the port B1212; the rope segment end c is at the same end as the port D1222, the rope segment end d is at the same end as the port C1221, the rope segment end e is at the same end as the port C1221, and the rope segment end f passes through the inner circle of the first bending portion 24 and is limited at the ports B1212 and D1222; the first bending portion 24 is connected between the rope segment end b and the rope segment end c, and the second bending portion 25 is connected between the rope segment end d and the rope segment end e. During actual use, the rope connecting section passes through hole monomer 121 and hole monomer 2 122 in sequence, so that the first rope segment 21 is in hole monomer 121, the second rope segment 22 is in hole monomer 2 122, and the third rope segment 23 is outside hole monomer 121 and hole monomer 2 122, and the rope segment end f of the third rope segment 23 passes through the inner circle of the first bending portion 24. The first bending portion 24 serves as a structure for bending the first rope segment 21 and the second rope segment 22, and can press the rope segment end f to form a pressure head. The second bending portion 25 serves as a structure for bending the second rope segment 22 and the third rope segment 23, so that the third rope segment 23 is wrapped from the outside of the shaft body 11 to the first bending portion 24, and the rope segment end f passes through the inner circle of the first bending portion 24 and is limited at the port B1212 and the port D1222. The greater the tension of the rope object 2, the tighter the rope segment end f will be pressed by the first bending portion 24, locking the rope object 2 and making it difficult for the rope object 2 to escape from the hole monomer 121 and the hole monomer 2 122. Moreover, the first bending portion 24 adapts to the port B1212 of the hole monomer 121 and the port D1222 of the hole monomer 2 122 and the rope segment end f at the same hole end, and the second bending portion 25 adapts to the port C1221 of the hole monomer 2 122. Each bending portion forms a friction contact structure equivalent to a knotted and tied structure, which can further withstand a certain pulling force without falling out of the connecting hole 12. In particular, when the rope object 2 is a steel wire rope, based on the hardness of the steel wire rope and the friction force generated by the stress concentration at the bending point and the lever bending force in different directions generated by the three rope segments at the bending point, even if the far end of the steel wire rope is subjected to a large pulling force, the rope connecting segment of the steel wire rope will be stuck in the connecting hole 12 and will not fall off.

[0039] A preferred embodiment thereof is as follows Figure 6-8As shown, the rope connecting section also includes a fourth rope segment 26 and a third bend 27. The fourth rope segment 26, the second rope segment 22, the third rope segment 23 and the first rope segment 21 are sequentially away from the rope head end; the first bend is between the first rope segment 21 and the third rope segment 23, the second bend 25 is between the third rope segment 23 and the second rope segment 22, and the third bend 27 is between the second rope segment 22 and the fourth rope segment 26; the rope segment end a is at the same end as the port A1211, and the rope segment end b is at the same end as the port B1212; the rope segment end e is at the same end as port B1212, rope segment end f is at the same end as port C1221; rope segment end c is at the same end as port C1221, rope segment end d is at the same end as port D1222; the first bending portion 24 is connected between rope segment end b and rope segment end e, the second bending portion 25 is connected between rope segment end f and rope segment end c, the third bending portion 27 is connected between rope segment end d and the fourth rope segment 26; the fourth rope segment 26 passes through the inner side of the third rope segment 23 and is limited between the third rope segment 23 and the shaft body 11.

The first bending portion 24 is a structure for bending the first rope segment 21 and the third rope segment 23, the second bending portion 25 is a structure for bending the second rope segment 22 and the third rope segment 23, and the third bending portion 27 is a structure for bending the second rope segment 22 and the fourth rope segment 26, so that the fourth rope segment 26 is wrapped from the outside of the shaft body 11 to the third rope segment 23 and the fourth rope segment 26 passes through the inner circle of the third rope segment 23 and is limited between the third rope segment 23 and the shaft body 11. When the tension of the rope object 2 is greater, the fourth rope segment 26 will be pressed tighter by the third rope segment 23, forming a pressure head, locking the rope object 2, and making it difficult for the rope object 2 to escape from the hole monomer 121 and the hole monomer 2 122. Moreover, the first bent portion 24 adapts to the port B1212 of the hole monomer 121, the second bent portion 25 adapts to the port C1221 of the hole monomer 2 122, and the third bent portion 27 adapts to the port D1222 of the hole monomer 2 122.

The rope segment end d passes through the inner circle of the first bending portion 24 and is limited at the port B1212 and the port D1222. The greater the tension of the rope object 2, the tighter the rope segment end d will be pressed by the first bending portion 24, locking the rope object 2 and making it difficult for the rope object 2 to escape from the hole monomer 1 121 and the hole monomer 2 122.

Each bending portion forms a friction contact structure equivalent to a knotted and tied structure, which can withstand a certain pulling force without falling out of the connecting hole 12, especially when the rope object 2 is a steel wire rope, based on the hardness of the steel wire rope and the friction force generated by the stress concentration at the bending point and the lever bending force in different directions generated by the three rope segments at the bending point, even if the far end of the steel wire rope is subjected to a large pulling force, the rope connecting section of the steel wire rope will be stuck in the connecting hole 12 and will not fall off.

[0042] Further preferably, the shaft body 11 is formed with a notch 13 at the end of the connecting hole 12. The notch 13 can accommodate at least one of the bending portion of the rope object 2 and the end of the rope object 2, so as to prevent the rope object 2 from protruding too much and affecting the winding of the rope object 2 on the shaft body 11; the notch 13 is also convenient for the formation of the hole monomer 1 121 and the hole monomer 2 122, and makes it difficult for the edges of the hole monomer 1 121 and the hole monomer 2 122 to be very thin and easily damaged by the rope object 2. The specific structure can be that the shaft body 11 is formed with notches 13 at both ends of the connecting hole 12, which is convenient for accommodating the bending portion and the rope end of the rope object 2, and is convenient for the user to thread the rope in any direction.

[0043] Preferably, the extending directions of the hole monomer 121 and the hole monomer 2 122 are parallel. The parallel hole monomer 121 and the hole monomer 2 122 are not only conducive to the simultaneous demolding and molding in the same direction, but also convenient for the user to thread the rope, and it is easy to make the bending angle of each bending part in a larger state, ensuring the locking force of the rope object 2.

[0044] Further preferably, the other side of the shaft body 11 also has a connection hole 12. This connection hole 12 also includes a hole monomer 121 and a hole monomer 2 122. The two connection holes 12 on the opposite side can be connected to the two rope connection sections of the rope object 2 one by one, which is convenient for winding or unwinding the rope object 2. The specific structure can be that the hole monomers of the two connection holes 12 on the opposite side are parallel, which is conducive to simultaneous demolding and demolding in the same direction; further, the connection holes 12 on the opposite side are radially symmetrical or centrally symmetrical, which is convenient for users to thread the rope in any direction, which is more convenient.

[0045] The product form of the utility model is not limited to the illustrations and embodiments of this case. Any appropriate changes or modifications made by anyone with similar ideas should be deemed to be within the patent scope of the utility model.
