[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-4 A connecting mechanism for metal spokes includes a spoke body 1. Multiple elastic retaining tubes 11 are installed in a circular array at equal intervals on the outer end of the spoke body 1. The elastic retaining tubes 11 are evenly divided into four segments. The outer side of the retaining tubes 11 is provided with an external thread. A pressing member 3 is inserted into the inner side of the elastic retaining tubes 11. A connecting member 2 is screwed onto the outer side of the retaining tubes 11. One end of the connecting member 2 is provided with a threaded groove at the elastic retaining tube 11. The other side of the connector 2 has an insertion hole for the pressing member 3 to pass through, and multiple L-shaped limiting members 22 are arranged in a circular array at equal intervals on the side of the connector 2 away from the thread groove. The side of the connector 2 away from the thread groove has a detachable limiting member 21. The connector 2 and the limiting member 21 are limited by the L-shaped limiting member 22.

[0016] The pressing component 3 includes a connecting ring 31, a pressing block 32 is installed on one side of the connecting ring 31, and the outer diameter of the pressing block 32 is the same as the inner diameter of the elastic retaining tube 11. An auxiliary protrusion is installed on the side of the pressing block 32 away from the connecting ring 31, and the auxiliary protrusion is conical.

[0017] Multiple positioning elements 23 are installed in a ring array at equal intervals inside the socket. The cross-section of the positioning element 23 is T-shaped. The outer wall of the connecting ring 31 is provided with an inlet / outlet groove 311 at the corresponding positioning element 23. The outer wall of the connecting ring 31 is provided with a locking groove 312 on the side of the inlet / outlet groove 311 for the positioning element 23 to slide.

[0018] The limiting component 21 includes a pressing ring 212. One end of the pressing ring 212 is located at the inlet / outlet slide groove 311 and a limiting block 213 is installed thereon. The other side of the pressing ring 212 is equipped with a T-shaped positioning ring 214, and a movable ring 211 is movably sleeved on the outside of the T-shaped positioning ring 214.

[0019] The outer wall of the movable ring 211 is provided with a sliding groove 215 at the L-shaped limiting member 22, and flexible protrusions are symmetrically installed on both sides of the sliding groove 215.

[0020] An auxiliary groove is provided on the side of the spoke body 1 near the elastic retaining tube 11 at the auxiliary protrusion.

[0021] In this embodiment, the connecting ring 31 of the pressing member 3 is inserted into the end of the connector 2 with the insertion hole. The inlet / outlet groove 311 on the connecting ring 31 is aligned with the positioning member 23 inside the connector 2. The pressing member 3 is pushed all the way down, and then the connecting ring 31 is rotated so that the positioning member 23 slides from the inlet / outlet groove 311 into the end of the locking groove 312. At this time, the pressing member 3 is connected to the connector 2.

[0022] Next, insert the T-shaped positioning ring 214 of the limiting member 21 into the movable ring 211. Then, align the limiting insert 213 with the entrance of the inlet / outlet groove 311 on the connector 2 and gently push it in so that the limiting insert 213 enters the locking groove 312. Before insertion, ensure that the sliding groove 215 on the outer wall of the movable ring 211 is aligned with the L-shaped limiting member 22. After insertion, rotate the movable ring 211 until its sliding groove is away from the L-shaped limiting member.

[0023] Next, align the elastic retaining tube 11 at the end of the spoke body 1 with the pressure block 32 at the front end of the pressure member 3, and make sure to align the auxiliary protrusion and the auxiliary groove. Gently push the spoke body 1 in so that the elastic retaining tube 11 fits onto the pressure block 32. During the pushing process, rotate the spoke body 1. Since the outer wall of the elastic retaining tube 11 has external threads, the elastic retaining tube 11 is threadedly connected to the threaded groove of the connector.

[0024] At the same time, as it is continuously tightened, the elastic retaining tube 11 is pulled into the connector 2, and its open end is spread along the conical surface of the pressure block 32, generating a strong radial expansion force, tightly holding the pressure block 32. After the threads are fully tightened, the installation of the connector and the spoke body 1 is completed.

[0025] When it is necessary to disassemble the connector, rotate the movable ring 211 so that its sliding groove is aligned with its L-shaped limiting member 22 and then pull it out. Then rotate the connecting ring 31 so that the positioning member 23 slides from the locking groove 312 into the end of the inlet and outlet groove 311. Then the pressing member 3 can be pulled out. At this time, the elastic locking tube loses its internal support force and one end of its elastic locking tube tilts inward, which makes it easy for the user to quickly disassemble the connector.

[0026] In this utility model, the connecting piece 2, the limiting piece 21, the pressing piece 3, the L-shaped limiting piece 22 and the positioning piece are arranged in a coordinated manner to enable the user to quickly assemble and disassemble the spoke body and the connecting piece 2.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
