Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Figure 2 for Figure 1 Exploded view; Figure 3 for Figure 1 Schematic diagram of the middle rope connector; Figure 4 for Figure 1 Schematic diagram of the middle rod joint; Figure 5 This is a schematic diagram illustrating the use of adapters to connect rods and ropes.

[0030] In one specific embodiment, the adapter for connecting rods and ropes provided by this utility model includes a rope connector 1, a rod connector 2, and a fastener 3. The first end of the rope connector 1 is connected to a rope 4, with the rope 4 perpendicular to the first side of the rope connector 1. The first end of the rope connector 1 can be secured using a compression sleeve method or a rope clamp method to ensure a secure connection of the rope 4. The first end of the rod connector 2 is connected to a rod 5, which is installed along the axial direction of the rod connector 2. The first end of the rod connector 2 can be connected to the rod 5 via a threaded connection or a snap-fit ​​method. The second end of the rope connector 1 and the second end of the rod connector 2 are rotatably connected by the fastener 3. The axis of rotation of the fastener 3 is perpendicular to the second side of the rope connector 1, and the axis of rotation is perpendicular to both the rope 4 and the rod 5. The fastener 3 can be a rotating shaft, an adjustable spherical bearing, or a universal joint to achieve connections at different angles.

[0031] The adapter provided by this utility model for connecting rods and ropes has a rope connector 1 and a rod connector 2 connected by a fastener 3. The rope 4 and the rod 5 can be freely adjusted within a certain angle range, improving the flexibility of the connection and solving the problem of fixed connection angle in traditional connection methods. It is suitable for rods 5 and ropes 4 of various diameters. By replacing the rope connector 1 and rod connector 2 with different specifications, different usage requirements can be met, showing good versatility. Compared with welding, this connection method is easier to install and disassemble, and does not produce weld scars, reducing the risk of impact.

[0032] Based on the above specific embodiments, the rope connector 1 includes an upper connector and a lower connector that are fastened together. The first end sidewalls of the upper connector and the lower connector are provided with semi-circular holes. After the upper connector and the lower connector are fastened together, the semi-circular holes of the two connectors form a circular hole, and the rope 4 is connected in the circular hole.

[0033] In one specific embodiment, the rope connector 1 includes an upper connector and a lower connector, which are connected by a snap-fit ​​mechanism, such as a clip, bolt, or other mechanical fastening method. Both the upper and lower connectors have semi-circular holes on their first end sidewalls, with the shape and size of the semi-circular hole in the lower connector matching that in the upper connector. When the upper and lower connectors are snapped together, the two semi-circular holes form a complete circular hole. The rope 4 is inserted into the circular hole and secured in it using bolts or clips or other fasteners 11, ensuring a secure connection between the rope 4 and the rope connector 1.

[0034] The split structure of the rope connector 1 makes the installation and disassembly of the rope 4 more convenient, without the need for complicated tools or operations; the appropriate size of the semi-circular hole can be selected according to the diameter of the rope 4, which is suitable for ropes 4 of different diameters.

[0035] Preferably, sealing gaskets are provided in the semi-circular holes of the upper and lower connectors, which can prevent moisture or dust from entering the connection surface between the circular holes and the rope 4, and can also make the upper and lower connectors hold the rope 4 tightly without damaging the rope 4.

[0036] Based on the above specific embodiments, the inner wall of the circular hole is provided with a protrusion 12. After the upper and lower connectors are fastened, the protrusion 12 presses against the rope 4. The protrusion 12 can increase the friction between the rope connector 1 and the rope 4, preventing the rope 4 from sliding inside the circular hole and improving the reliability of the connection; it can also prevent the rope 4 from tangling or rotating during use. Preferably, the end face of the protrusion 12 can be a plane or a triangular pyramidal surface. The protrusion 12 can be a rivet riveted to the inner wall of the circular hole, which has a simple structure and is easy to connect.

[0037] In a preferred embodiment, since the bolt directly tightens the middle of the upper and lower connectors when they are fastened, the force is relatively large. Therefore, the number of protrusions 12 in the middle of the semicircular hole is greater than the number of protrusions 12 on both sides. That is, there are multiple protrusions 12 in the middle of the semicircular hole and fewer protrusions 12 on both sides. This can further increase the friction between the rope connector 1 and the rope 4, effectively prevent the rope 4 from sliding in the circular hole, and improve the reliability of the connection.

[0038] Based on the above specific embodiments, the inner wall of the circular hole is provided with a pin. After the upper connector and the lower connector are fastened together, the pin is inserted into the rope 4.

[0039] In one specific embodiment, a pin is provided on the inner wall of the circular hole. The rope 4 is inserted into the circular hole, and the pin is inserted into the rope 4. The pin precisely positions the connection between the rope joint 1 and the rope 4, restricting their relative movement and rotation. The pin can be a right-angled pin with a tapered bottom to better insert into the rope 4 and to prevent deformation, thereby increasing the connection strength between the rope joint 1 and the rope 4.

[0040] Based on the above specific embodiments, the upper and lower connectors have at least two cooperating positioning blocks 13 and positioning holes on their fastening surfaces. After the upper and lower connectors are fastened together, the positioning blocks 13 are connected in the positioning holes. The positioning blocks 13 and positioning holes position the upper and lower connectors at their fastening positions, ensuring that the upper and lower connectors are accurately aligned during fastening, preventing misalignment, and improving the stability and reliability of the fastening.

[0041] Based on the above specific embodiments, the rod joint 2 has an axial through hole, which is separated by a partition. The through hole forms a connecting rod hole at the first end of the rod joint 2 and a clearance hole at the second end of the rod joint 2. An insertion hole is provided on the partition. The connecting rod hole and the insertion hole form a stepped hole. The end of the rod 5 has a stepped shaft that matches the stepped hole. The stepped shaft and the stepped hole are connected by a locking member.

[0042] In one specific embodiment, the rod joint 2 has an axially provided through hole, which is separated by a partition and divided into a connecting rod hole and a clearance hole. The connecting rod hole is located at the first end of the rod joint 2 and is used to connect with the rod 5. The clearance hole is located at the second end of the rod joint 2 and is used to avoid and accommodate the stepped shaft of the rod 5.

[0043] The partition plate has insertion holes, and the connecting rod hole and the insertion holes form a stepped hole. The end of the rod 5 has a stepped shaft that matches the stepped hole. The stepped shaft ensures a firm connection between the rod 5 and the rod joint 2, and is further secured by a locking device. The stepped shaft and the stepped hole are connected by a locking device, which can be a nut, thread, or other fastener 3. The locking device fixes the stepped shaft of the rod 5 in the stepped hole of the rod joint 2, ensuring the reliability and stability of the connection and preventing the connection between the rod 5 and the rod joint 2 from loosening.

[0044] The stepped hole and stepped shaft achieve a tight fit between rod 5 and rod joint 2, resulting in a compact structure; the locking component ensures a firm connection between rod 5 and rod joint 2, improving the reliability of the connection; the detachable connection facilitates the installation and disassembly of rod 5, improving assembly efficiency.

[0045] Based on the above specific embodiments, the end section of the stepped shaft is provided with external thread, the stepped hole is a smooth shaft, the stepped surface of the stepped shaft abuts against the first surface of the partition, the end of the stepped shaft is fastened by a nut, and the locking member abuts against the second surface of the partition.

[0046] In one specific embodiment, the end of the rod 5 is a stepped shaft that matches the stepped hole. The end section of the stepped shaft has external threads. The stepped shaft of the rod 5 is inserted into the stepped hole of the rod connector 2, and the stepped surface of the stepped shaft fits tightly against the first surface of the partition. A nut is screwed onto the end of the stepped shaft, and tightening the nut securely connects the rod 5 and the rod connector 2. The nut acts as a locking element, abutting against the second surface of the partition to ensure the stability of the connection. The external thread connection between the nut and the stepped shaft has self-locking properties, ensuring a firm connection that is not easily loosened.

[0047] Alternatively, the insertion hole of the partition plate can be a threaded hole, and the external thread of the end section of the stepped shaft can be threaded to the threaded hole, using the threaded hole instead of a nut to eliminate the nut and simplify the structure. Furthermore, the threaded connection between the rod joint 2 and the rod 5 facilitates adjustment of the length of the rod 5, improving the flexibility of use.

[0048] Based on the above specific embodiments, the rod joint 2 has a countersunk hole 21 on the second surface of the partition, the locking member is built into the countersunk hole 21, the countersunk hole 21 and the locking member are clearance fit, the cross sections of the countersunk hole 21 and the locking member are polygonal, and the surfaces of the locking member and the partition are provided with interlocking concave and convex surfaces.

[0049] In one specific embodiment, the stepped shaft of the rod 5 is inserted into the stepped hole of the rod connector 2, ensuring that the stepped surface of the stepped shaft is tightly fitted with the first surface of the partition. A secure connection between the rod 5 and the rod connector 2 is achieved by tightening the locking element. The partition has a countersunk hole 21 on its second surface, into which locking elements such as nuts are installed. The countersunk hole 21 and the locking element have polygonal cross-sections, and the countersunk hole 21 and the locking element are clearance-fitted. The countersunk hole 21 circumferentially limits the locking element, restricting its rotation and effectively preventing loosening, thus improving the reliability of the connection.

[0050] The surfaces of the locking element and the partition are provided with interlocking concave and convex surfaces, which can not only further enhance the friction between the locking element and the partition to prevent loosening, but also further restrict the circumferential rotation of the locking element to ensure the firmness of the connection.

[0051] Based on the above specific embodiments, the second end of the rope connector 1 is provided with a insert plate, the second end of the rod connector 2 is provided with a groove, and the second sides of both the rope connector 1 and the rod connector 2 are provided with connecting holes. The insert plate is connected to the groove, and the screw is connected to the connecting holes of both and fastened by screws.

[0052] In one specific embodiment, the second end of the rope connector 1 is provided with an insert plate, and the second end of the rod connector 2 is provided with a groove. The shape and size of the insert plate of the rope connector 1 match the groove of the rod connector 2. The stepped shaft of the rod 5 is inserted into the stepped hole of the rod connector 2, ensuring that the stepped surface of the stepped shaft is in close contact with the first surface of the partition. The insert plate of the rope connector 1 is inserted into the groove of the rod connector 2, ensuring that the two fit tightly together. Both the second side of the rod connector 2 and the rope connector 1 are provided with connecting holes. A screw is inserted into the connecting holes of the rope connector 1 and the rod connector 2, and the screw is tightened with a screw to ensure a firm connection between the rope connector 1 and the rod connector 2.

[0053] The combination of the insert plate and the groove, as well as the fastening method of the screw and bolt, results in a simple structure that makes the installation and disassembly of the rope connector 1 and the rod connector 2 more convenient.

[0054] Based on the above specific embodiments, the insert plate is an arc plate, and the groove is an arc groove. The arc plate and the arc groove cooperate to ensure smooth rotation and prevent jamming when the rope connector 1 and the rod connector 2 rotate relative to each other. An elastic washer is pressed between the arc plate and the arc groove, which neither affects the relative rotation of the rope connector 1 and the rod connector 2, nor hinders the friction between them, preventing them from continuing to rotate after they are positioned. The elastic washer presses against the locking element, providing cushioning and anti-loosening functions for the locking element.

[0055] An elastic stepped sleeve is pressed between the stepped hole and the stepped shaft. The elastic stepped sleeve can increase the friction between the stepped hole and the stepped shaft, providing cushioning and anti-loosening functions, and ensuring the stability and reliability of the connection.

[0056] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
