[0026] Refer to the attached Figure 1 , Attachment Figure 2 A wear-resistant quick-assembly universal joint fork comprises a universal joint fork body 1, the universal joint fork body 1 comprises two universal joint fork arms 2, the two universal joint fork arms 2 are assembled together, a buckle groove 4 is arranged on the outer surface of the universal joint fork arms 2, the two matched universal joint fork arms 2 are wrapped with two limit connecting sleeves 5 on the outside, the two limit connecting sleeves 5 are symmetrically distributed, and the two sides of the limit connecting sleeves 5 are respectively connected with a buckle strip 10 in one piece, and the two buckle strips 10 on the same limit connecting sleeve 5 are respectively buckled in the buckle grooves 4 on the outer surfaces of the two universal joint fork arms 2, the limit connecting sleeve 5 is semi-circular, and the appearance of the limit connecting sleeve 5 Latch holes 6 are provided at corresponding positions on the surface and the outer surface of the universal joint fork arm 2, and latch bolts 7 are inserted inside the latch holes 6, wherein two matching limit connecting sleeves 5 can be used to limit and fix the two matching universal joint fork arms 2, and then when assembling and disassembling the universal joint fork body 1, the two limit connecting sleeves 5 can be directly pulled out, and then the two universal joint fork arms 2 are separated, so that the universal joint fork arms 2 can be conveniently separated from both ends of the cross shaft. The entire assembly and disassembly operation is flexible and convenient, which greatly improves the efficiency of the inspection and replacement of the universal joint fork, and at the same time, the damaged parts can be replaced flexibly and conveniently, and the practicality is effectively improved.

[0027] Reference Figure 1 , Figure 2 A shaft mounting hole 8 is provided at the upper end of the universal joint yoke arm 2, and the shaft mounting holes 8 on the two universal joint yoke arms 2 have a common central axis. A transmission shaft connecting hole 9 is provided on the end surface of the universal joint yoke arm 2, in which the combined universal joint yoke body 1 can be effectively installed at one end of the transmission shaft, while ensuring that the cross shaft stably rotates inside the matched universal joint yoke arm 2.

[0028] Reference Figure 1 , Figure 3A mounting hole is provided on the inner side surface of the universal joint fork arm 2, and a graphene inner tube ring 3 is installed with a buckle inside the mounting hole. A plurality of arc ridges 11 are integrally connected to the inner wall of the graphene inner tube ring 3, and the spacing between two adjacent arc ridges 11 is consistent, wherein the graphene inner tube ring 3 can be used to wrap the rotating end of the cross shaft. When the universal joint is working, the cross shaft rotates inside the graphene inner tube ring 3, thereby avoiding direct friction between the rotating end of the cross shaft and the universal joint fork arm 2, effectively improving the wear resistance and service life of the universal joint fork. Since a plurality of arc ridges 11 are provided on the inner wall of the graphene inner tube ring 3, the contact area between the cross shaft and the graphene inner tube ring 3 can be reduced, further reducing the wear loss of the entire universal shaft during rotation.

[0029] Working principle: When in use, the universal joint shaft is assembled first. During assembly, the graphene inner tube ring 3 is first buckled into the mounting hole on the inner side of the universal joint fork arm 2, and then the universal joint fork arm 2 is sleeved on the end of the cross shaft, so that the graphene inner tube ring 3 is sleeved on the outer side of the end of the cross shaft, and the two universal joint fork arms 2 are matched at the same time, and then the two limit connecting sleeves 5 are respectively installed on the outside of the matched universal joint fork arms 2, and then the universal joint shaft is installed at one end of the transmission shaft, and then the latch bolt 7 is passed through the inside of the latch hole 6. At this time, the universal joint The shaft is assembled and can be used normally. Since the graphene inner tube ring 3 is used to wrap the rotating end of the cross shaft, when the universal joint is working, the cross shaft rotates inside the graphene inner tube ring 3, which avoids the rotating end of the cross shaft from directly rubbing against the universal joint fork arm 2, effectively improving the wear resistance and service life of the universal joint fork. Since a plurality of arc convex strips 11 are provided on the inner wall of the graphene inner tube ring 3, the contact area between the cross shaft and the graphene inner tube ring 3 can be reduced, further reducing the wear loss of the entire universal joint when rotating.
