[0004] The utility model provides the following technical solutions:

[0005] A rod end joint bearing for outdoor use comprises a rod end body and a built-in bearing. A through groove is provided at one end of the rod end body, and the built-in bearing is fixed in the through groove. The built-in bearing comprises an outer ring. The outer sides of the rod end body and the outer ring are both provided with an electroplating layer, and the electroplating layer is a zinc-nickel alloy layer. The zinc-nickel alloy layer on the surface effectively prevents the rod end joint bearing from corrosion and rust, and can withstand a neutral salt spray test for more than 480 hours.

[0006] Furthermore, the built-in bearing also includes self-lubricating material and a joint ball. The inner side of the outer ring is provided with a groove, the self-lubricating material is located in the groove, the joint ball is rotatably located inside the outer ring, and the outer surface of the joint ball abuts against the self-lubricating material.

[0007] Furthermore, the joint ball is made of stainless steel, which has good corrosion resistance and is convenient for outdoor use.

[0008] Furthermore, the rod end body is an internally threaded rod end body, and the other end of the rod end body is a connecting rod, which is cylindrical or cylindrical with steps.

[0009] Technical effects and advantages of the utility model:

[0010] The utility model effectively prevents the rod end joint bearing from being corroded and rusted by electroplating the zinc-nickel alloy layer, and can withstand a neutral salt spray test for more than 480 hours. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] like Figure 1-3 As shown, an outdoor rod end joint bearing includes a rod end body 1 and a built-in bearing 2. A through groove 11 is provided at one end of the rod end body 1. The built-in bearing 2 is fixed in the through groove 11. The built-in bearing 2 includes an outer ring 21. The outer sides of the rod end body 1 and the outer ring 21 are both provided with an electroplating layer, and the electroplating layer is a zinc-nickel alloy layer.

[0016] The zinc-nickel alloy layer has good corrosion resistance and beautiful appearance. The zinc-nickel alloy layer on the surface effectively prevents the rod end joint bearing from corrosion and rust, and can withstand more than 480 hours of neutral salt spray test.

[0017] Salt spray test is an environmental test that mainly uses artificial simulated salt spray environment conditions created by salt spray test equipment to evaluate the corrosion resistance of products or metal materials. The neutral salt spray test uses a 5% sodium chloride saline solution with a pH value adjusted to a neutral range (6-7) as a spray solution. The test temperature is 35°C, and the salt spray sedimentation rate is required to be between 1-2ml / 80cm2.h.

[0018] The built-in bearing 2 also includes a self-lubricating material 23 and a joint ball 22. A groove is provided on the inner side surface of the outer ring 21. The self-lubricating material 23 is located in the groove. The joint ball 22 is rotatably located inside the outer ring 21. The outer surface of the joint ball 22 abuts against the self-lubricating material 23. The joint ball 22 is rotatably located in the outer ring 21 through the self-lubricating material 23. During the lubrication process, no dirt enters between the joint ball 22 and the outer ring 21 to cause contamination. The joint ball 22 and the outer ring 21 have a large sliding contact area and a large inclination angle, so they can work normally even if they are installed misaligned.

[0019] The joint ball 22 is made of stainless steel, which has good corrosion resistance and is convenient for outdoor use. The self-lubricating material 23 is a sintered fabric of PTFE material and copper mesh or a braid of PTFE fiber and Kevlar fiber.

[0020] The rod end body 1 is an internally threaded rod end body 1, and the other end of the rod end body 1 is a connecting rod 12, which is cylindrical or cylindrical with steps and has a large load resistance. A cylindrical flange is arranged at the lower part of the existing rod end body 1, and a flat wrench position is arranged on the front and rear sides of the flange. The wrench position is used to fix the rod end joint bearing, and the connecting rod 12 is rotatably fixed through one end of the through groove 11 of the rod end body 1, and no wrench position is arranged, thereby reducing the material consumption of the flange part and the milling process of the wrench position.

[0021] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
