[0021] Please refer to Figures 1-6, A non-equal three-fork joint for a beach vehicle, including a connecting piece 1. A shaft body 2 is fixedly connected to the outside of the connecting piece 1. A universal sphere 3 is in contact with the outside of the shaft body 2. A chute 4 is opened inside the shaft body 2. A slide bar 5 is slidably connected inside the chute 4. One end of the slide bar 5 away from the chute 4 is fixedly connected to a handle 6. The handle 6 is in contact with the universal sphere 3. A tension spring 7 is arranged inside the universal sphere 3. One end of the tension spring 7 is fixedly connected to a pull block 8. The other end of the tension spring 7 is fixedly connected to the universal sphere 3. The pull block 8 is slidably connected inside the universal sphere 3. One end of the pull block 8 away from the tension spring 7 is fixedly connected to the handle 6. By designing the handle 6, it can be used to drive components such as the slide bar 5 to move. A guiding groove 9 is opened inside the universal sphere 3. A guiding block 10 is slidably connected inside the guiding groove 9. The guiding block 10 is fixedly connected to the pull block 8. By designing the guiding block 10, the pull block 8 can be guided. The universal sphere 3 is slidably connected to the slide bar 5. A sealing mechanism 11 is arranged inside the universal sphere 3. By pulling the slide bar 5 to a specified position, and then moving the universal sphere 3 to drive components such as the slide bar 5 and the semi-circular sealing sleeve 116 to a specified position on the shaft body 2, and then moving the slide bar 5 into the chute 4, thereby limiting the universal sphere 3, making it convenient to connect the shaft body 2 and the universal sphere 3 on the device.

[0022] Please refer to Figure 5 , The sealing mechanism 11 includes a screw rod 111. The screw rod 111 is threadedly connected inside the universal sphere 3. A rotating block 112 is fixedly connected to the screw rod 111. An annular sleeve 113 is rotatably connected to the outside of the screw rod 111. A bolt 114 is threadedly connected inside the annular sleeve 113. An annular groove 115 is opened inside the screw rod 111. The bolt 114 is slidably connected inside the annular groove 115. By designing the bolt 114, the screw rod 111 and the annular sleeve 113 can be connected.

[0023] Please refer to Figure 3 , Figure 5 , Figure 6 , A semi-circular sealing sleeve 116 is fixedly connected to the annular sleeve 113. A sliding groove 117 is opened inside the universal sphere 3. A guide rod 118 is slidably connected inside the sliding groove 117. The guide rod 118 is fixedly connected to the semi-circular sealing sleeve 116. By designing the guide rod 118, the semi-circular sealing sleeve 116 can be guided. The semi-circular sealing sleeve 116 is in contact with the shaft body 2. By rotating the screw rod 111 to perform a threaded movement with the universal sphere 3, the screw rod 111 rotates to drive components such as the semi-circular sealing sleeve 116 to move. The semi-circular sealing sleeve 116 moves to contact a specified position on the shaft body 2, thereby sealing the inside of the universal sphere 3 and making the device convenient to use.

[0024] The specific implementation process of the present utility model is as follows: A non-equal three-fork joint for a beach vehicle provided by the present utility model adopts a non-equal method, which is beneficial to dispersing the force of the beach vehicle; the minimum radius of the root arc of the spline teeth of the three-fork joint is 0.3 mm to avoid sharp corners and increased stress; the arc of the relief groove at the journal part of the three-fork joint should not exceed R0.8 to prevent stress concentration. This non-equal three-fork joint for a beach vehicle uses the process method of warm precision forging, combining the advantages of cold forging process and hot forging process, and improving the surface quality and dimensional accuracy of the three-fork joint.

[0025] Before the device is used, pull the handle 6 to move away from the globe 3. The movement of the handle 6 drives the slide rod 5 and the pull block 8 to move. The movement of the pull block 8 drives the guide block 10 to move. The movement of the pull block 8 stretches the pull spring 7. After the slide rod 5 and other components move to the designated position, move the globe 3 to drive the slide rod 5 and the semi-circular sealing sleeve 116 and other components to move to the designated position on the shaft body 2. Then release the handle 6. The pulling force of the pull spring 7 drives the pull block 8 to move. The movement of the pull block 8 drives the guide block 10 and the handle 6 to move. The movement of the handle 6 drives the slide rod 5 to move. The slide rod 5 moves into the chute 4, thereby limiting the globe 3 and facilitating the connection between the shaft body 2 and the globe 3 on the device.

[0026] When the inside of the shaft body 2 needs to be sealed, rotate the rotating block 112. The rotation of the rotating block 112 drives the screw 111 to rotate. The rotation of the screw 111 makes a threaded movement with the globe 3, thereby causing a relative displacement of the screw 111. The rotation of the screw 111 drives components such as the annular sleeve 113 to move. The movement of the annular sleeve 113 drives the semi-circular sealing sleeve 116 to move. After the semi-circular sealing sleeve 116 moves into contact with the designated position on the shaft body 2, the inside of the globe 3 is sealed, making the device easy to use.

[0027] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
