[0002] The universal joint is a universal joint, which is a machine part for realizing variable-angle power transmission and is used in positions where the direction of the transmission shaft needs to be changed. It is the "joint" component of the universal transmission device of the automobile drive system. The universal joint and the transmission shaft are combined, and are called a universal joint transmission device.
[0003] In the transmission process of the traditional universal joint, although the torque can be effectively transmitted and a certain angular deviation between the transmission shafts is allowed, the complex locking structure and disassembly and assembly process limit its application in the high-efficiency maintenance environment. In addition, the traditional locking mechanism often relies on threaded fastening or pin fixing, and these methods are prone to cause part wear after frequent disassembly and assembly, affecting the locking effect and transmission stability.

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0015] like Figure 1 , Figure 2 As shown, this novel universal joint includes a first bogie 1 and a second bogie 2. One end of the first bogie 1 is provided with a connecting shaft 3, and the other end of the first bogie 1 is provided with a connecting portion 4. A first rotating rod 5 is provided on the inner wall of the connecting portion 4. The second bogie 2 is provided with a connecting portion 6, and a second rotating rod 7 is provided on the connecting portion 6. The first rotating rod 5 and the second rotating rod 7 are connected by a transmission block 8. The transmission block 8 has a first insertion hole 9 and a second insertion hole 10 for inserting the first rotating rod 5 and the second rotating rod 7. The second rotating rod 7... The two ends of the two insertion holes 10 are inserted into the transmission block 8, and the interior of the second rotating rod 7 is hollow. The first rotating rod 5 is inserted into the first insertion hole 9, and the second rotating rod 7 is inserted into the two ends of the second insertion hole 10 respectively and abuts against the first rotating rod 5. A limit ring 11 is provided on the inner wall of the second rotating rod 7. A snap-fit assembly is provided inside the second rotating rod 7. An elastic button 12 is provided on the snap-fit assembly. The bottom of the elastic button 12 is located inside the second rotating rod 7 and has two bent elastic brackets 13. The elastic brackets 13 enter the transmission block 8 through the limit ring 11.
[0016] When the elastic support 13 is deeply inserted into the second rotating rod 7, the elastic support 13 is compressed to pass through the limiting ring 11, which is used to fix the elastic support 13 to prevent the clamping block at the bottom of the elastic support 13 from suddenly loosening and falling out. When the clamping assembly is completely inserted into the second rotating rod 7, the elastic support 13 is loosened, the reset spring 16 is reset and abuts against the limiting ring 11 to prevent the clamping assembly from loosening. If the second rotating rod 7 needs to be replaced, the clamping assembly only needs to be pulled out for replacement. The diameter of the elastic button 12 is slightly larger than that of the second rotating rod 7, which effectively prevents the second rotating rod 7 from suddenly flying out during work.
[0017] Further, the second insertion hole 10 is provided with a clamping groove 14 on the inner wall for clamping, and the bottom of the elastic support 13 is provided with a circular clamping block 15 matched with the clamping groove 14. The reset spring 16 is arranged between the two elastic supports 13.
[0018] Further, the second rotating frame 2 is provided with an inner cavity 17 for installing the connecting shaft 3.
[0019] Further, the first rotating frame 1 and the second rotating frame 2 are both provided with through holes 18 for convenient installation and fixation.
[0020] Further, the elastic support 13 is made of a high-toughness elastic material.
[0021] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, without deviating from the spirit of the present application or exceeding the scope defined by the appended claims.
[0022] Although the terms such as the first rotating frame 1, the second rotating frame 2, the connecting shaft 3, the first connecting part 4, the first rotating rod 5, the second connecting part 6, the second rotating rod 7, the transmission block 8, the first insertion hole 9, the second insertion hole 10, the limiting ring 11, the elastic button 12, the elastic support 13, the clamping groove 14, the circular clamping block 15, the reset spring 16, the inner cavity 17, and the through hole 18 are used more frequently herein, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the present application; any kind of additional limitation by interpreting them is contrary to the spirit of the present application.
