DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0043] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0044] The server provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0045] Embodiment 1:

[0046] like Figure 1 As shown, an embodiment of the present application provides a high-strength rod-end joint bearing, including a bearing outer ring 1, a bearing inner ring 2 and a connecting rod 3, and also includes: a protective sleeve 4, which is fixedly connected to the upper end of the connecting rod 3; wherein the bearing outer ring 1 is installed in the protective sleeve 4.

[0047] Furthermore, it also includes a thickened end 5 which is arranged at the lower end of the protective sleeve 4 ; wherein the diameter of the thickened end 5 is greater than the diameter of the connecting rod 3 .

[0048] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the matched bearing outer ring 1 and the bearing inner ring 2 are installed in the protective sleeve 4, the lower end of the protective sleeve 4 is connected to the connecting rod 3, and a thickened end 5 is provided at the lower end of the protective sleeve 4. The diameter of the thickened end 5 is larger than the diameter of the connecting rod 3, thereby reinforcing the connection between the joint bearing and the connecting rod 3, thereby improving the overall hardness of the joint bearing and preventing it from breaking easily.

[0049] Embodiment 2:

[0050] like Figure 1 , Figure 2 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: a vibration reduction frame 6, which is fixedly connected between the protective cover 4 and the connecting rod 3; a pair of damping blocks 7, which are respectively fixedly mounted on the upper and lower inner walls of the vibration reduction frame 6; and a spring 8, which is fixedly connected between the pair of damping blocks 7.

[0051] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the joint bearing is easily affected by vibration during use, so a vibration damping frame 6 is fixedly connected between the protective sleeve 4 and the connecting rod 3. During vibration, the spring 8 inside the vibration damping frame 6 applies pressure to the damping blocks 7 at the upper and lower ends, and the damping blocks 7 support the spring 8, which can offset the vibration received by the joint bearing, thereby ensuring the stability of the joint bearing during use.

[0052] Embodiment 3:

[0053] like Figures 3 to 5 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: a rotating component 9, which is movably connected between the protective sleeve 4 and the connecting rod 3.

[0054] Furthermore, the rotating assembly 9 includes a rotating shaft 10 movably mounted on the connecting rod 3 ; a ball head 11 fixedly connected to the rotating shaft 10 ; and a slot 12 disposed in the middle of the ball head 11 .

[0055] Furthermore, it also includes a round head 13, which is arranged at the bottom end of the protective sleeve 4; wherein the round head 13 is movably installed in the slot 12, and the round head 13 is installed in the ball head 11 through a fastener 17.

[0056] Furthermore, it also includes a mounting groove 14, which is arranged at the top end of the connecting rod 3; an annular groove 15, which is arranged on the outer wall of the rotating shaft 10; a limiting hole 16, which is arranged on the connecting rod 3 and connected to the mounting groove 14; wherein the rotating shaft 10 can be rotatably installed in the mounting groove 14, and the rotating shaft 10 is fixed to the connecting rod 3 by a fastener 17.

[0057] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the swing angle of the joint bearing needs to be changed, the ball head 11 is inserted into the slot 12, and then the fastener 17 (a bolt and a nut are selected to be used in combination) is inserted into the screw into the connecting hole between the ball head 11 and the round head 13. The round head 13 drives the joint bearing to swing along the slot 12. When the joint bearing is rotated to the desired angle, the round head 13 is fixed to the ball head 11 by the connection between the nut and the bolt, and the lower end of the shaft 10 is inserted into the mounting groove 14. The shaft 10 can be The mounting groove 14 rotates 360°. When the rotating shaft 10 drives the spherical bearing to rotate to the required angle, bolts are inserted from the limiting holes 16 on both sides of the connecting rod 3 and the bolts are tightened into the annular groove 15. The bolt connection head is pressed against the inner wall of the annular groove 15, which limits the rotating shaft 10 and prevents the rotating shaft 10 from rotating freely in the connecting rod 3. The setting of the rotating shaft 10 can change the swing angle of the spherical bearing as well as the axial rotation angle of the spherical bearing. Through the combination of the two, the range of angle change of the spherical bearing is greatly improved.

[0058] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
