However, there is also the problem that it is not convenient enough during the assembly and connection of the rod end bearing, especially the stability of the internal assembly of the rod end bearing. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a rod end bearing.

[0006] The utility model is implemented by adopting the following technical solutions: A rod end bearing, including a bearing rod, an assembly component is provided at the top of the bearing rod, the assembly component is a bearing sleeve, the bearing sleeve and the bearing rod are assembled and connected to each other, an assembly bearing is provided inside the bearing sleeve, an assembly hole is provided on the assembly bearing, an assembly screw is provided in the assembly hole, an assembly space is provided on the bearing rod, an assembly thread is provided on the inner wall of the assembly space, and a rebound component is provided at the top of the assembly space, the rebound piece of the rebound component.

[0007] A top groove is provided at the top of the described assembly space. A resilient piece is arranged in the top groove, and a resilient portion is provided between the resilient piece and the top groove.

[0008] The resilient portion provided between the resilient piece and the top groove is a spring. The spring is connected to the resilient piece, and an external assembly groove is arranged on the resilient piece.

[0009] An oil injection hole is provided at the top of the bearing sleeve. The oil injection hole penetrates through the bearing sleeve, and an oil flow groove is arranged on the inner wall of the bearing sleeve.

[0010] Compared with the prior art, when the present utility model is in use, by utilizing the mutual cooperation of the bearing sleeve and the bearing rod, the assembly of the rod end bearing is made more convenient. An assembly space is arranged on the bearing rod, and an assembly thread for further assembly and locking is arranged in the assembly space, which can make the assembly of the rod end bearing more stable. A resilient piece is arranged in the assembly space, which can prevent the assembled screw from tightly abutting against the top of the bearing rod, making it inconvenient for subsequent disassembly between the screw and the bearing rod. The resilient piece can give some force to the top of the screw when the screw is loosened, which can facilitate the removal of the screw from the assembly space on the bearing rod.

[0012] Figure 2 is a perspective view of the present utility model;

[0013] Figure 3 is a sectional view of the present utility model;

[0014] In the figure: 1 is the bearing rod, 2 is the bearing sleeve, 3 is the assembled bearing, 4 is the assembly space, 5 is the resilient piece, 6 is the top groove, 7 is the spring, 8 is the external assembly groove, 9 is the oil injection hole, and 10 is the oil flow groove. Detailed Description of the Embodiment

[0015] Next, in combination with the drawings and the specific embodiments, the present utility model will be further described. It should be noted that on the premise of no conflict, the following described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.

[0016] A rod end bearing includes a bearing rod 1. An assembly component is provided at the top of the bearing rod 1. The assembly component is a bearing sleeve 2. The bearing sleeve 2 and the bearing rod 1 are assembled and connected to each other. An assembly bearing 3 is provided inside the bearing sleeve 2. An assembly hole is provided on the assembly bearing 3. An assembly screw is provided in the assembly hole. An assembly space 4 is provided on the bearing rod 1. Assembly threads are provided on the inner wall of the assembly space 4. A rebound component is provided at the top of the assembly space 4. The rebound component is a rebound piece 5.

[0017] When the rod end bearing needs to be assembled, an assembly space 4 can be provided on the bearing rod 1. Assembly threads are provided on the inner wall of the assembly space 4. In this way, the bearing rod 1 and the screw can be assembled well, making the assembly of the rod end bearing more stable. At the same time, in order to make the disassembly between the screw and the bearing rod 1 more labor-saving and convenient, the rebound piece 5 can be used to give a certain external force when disassembling the top of the screw, facilitating the disassembly of the screw from the bearing rod 1. A top groove 6 is provided at the top of the assembly space 4. The rebound piece 5 is provided in the top groove 6. A rebound part is provided between the rebound piece 5 and the top groove 6.

[0018] The rebound part provided between the rebound piece and the top groove is a spring 7. The spring 7 is connected to the rebound piece 5. An external assembly groove 8 is provided on the rebound piece 5. When the screw is assembled on the bearing rod, it will directly press against the top wall inside the bearing rod, which is not convenient for subsequent disassembly of the screw from the bearing rod, or the disassembly becomes not very convenient either. The rebound piece can be used to provide a partition between the screw and the top wall of the bearing rod, making the subsequent disassembly of the screw convenient. At the same time, an external assembly groove is provided on the rebound piece, which can well provide a certain assembly gap for the top of the screw.

[0019] In order to make the bearing inside the bearing sleeve 2 run more smoothly, an oil injection hole 9 can be provided at the top of the bearing sleeve 2. The oil injection hole 9 penetrates the bearing sleeve. Oil flow grooves 10 are provided on the inner wall of the bearing sleeve 2. Lubricating oil can be injected through the oil injection hole 9, so that the lubricating oil can flow into the inside of the bearing sleeve 2, and the injection and flow of the lubricating oil can be well carried out. When the lubricating oil flows, the oil flow grooves 10 can be used to control the oil path, meeting the functions of lubricating oil flow and lubricating the bearing.

[0020] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantive changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
