Description

Technical Field

[0001] The utility model belongs to the technical field of bushing processing, and particularly relates to a nylon bushing. Background Art

[0002] At present, most of the bushing used in the livestock breeding industry are stainless steel bushings, which have low flexibility. When encountering water or high humidity during use, they are very easy to rust. After rusting, it is more difficult to move, and the replacement operation is cumbersome and costly. Content of the Utility Model

[0003] The utility model provides a nylon bushing, which saves cost and simplifies operation by setting the nylon bushing as a split structure.

[0004] The utility model provides a nylon bushing, the nylon bushing is of an arc-shaped structure, one end of the nylon bushing is provided with a fixing column, and the other end is provided with a fixing hole.

[0005] Further, an arc-shaped fixing column is arranged on the inner side of the nylon bushing.

[0006] Further, a limiting part is arranged on the outer side of the arc-shaped fixing column, and a limiting hole matching with the limiting part is arranged on the steel plate bracket. The nylon bushing is installed on the steel plate bracket through the limiting hole and the limiting part. The arc-shaped fixing column and the limiting part together fix the nylon bushing on the steel plate bracket, ensuring that the nylon bushing and the steel plate bracket are on the same plane.

[0007] Further, the height of the connection surface of the fixing column is lower than the height of the plane where the nylon bushing is located, ensuring more stable connection with the fixing hole of another nylon bushing shaft.

[0008] Further, the height of the back surface of the connection surface of the fixing hole is lower than the height of the plane where the nylon bushing is located, ensuring more stable connection with the fixing column of another nylon bushing shaft.

[0009] Further, a fixing block is arranged on the outer side of the nylon bushing.

[0010] Further, a through hole is arranged on the fixing block. After fixing the nylon bushing on the steel plate bracket and passing a steel pipe through the nylon bushing shaft, the steel pipe can be further fixed by using bolts or self-tapping screws through the through hole.

[0011] The utility model provides a nylon bushing, which is convenient to control, simple to operate, and has an extended service life. Description of the Drawings

[0018] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0019] Such as Figure 1-2As shown in the figure, the present utility model provides a nylon bushing. The nylon bushing is of an arc-shaped structure. One end of the nylon bushing is provided with a fixing post 1, and the other end is provided with a fixing hole 2. An arc-shaped fixing post 3 is arranged inside the nylon bushing. A limiting portion 4 is arranged outside the arc-shaped fixing post 3. A limiting hole 6 matching the limiting portion 4 is arranged on a steel plate bracket 5. The nylon bushing is installed on the steel plate bracket 5 through the limiting hole 6 and the limiting portion 4. The arc-shaped fixing post 3 and the limiting portion 4 together fix the nylon bushing on the steel plate bracket 5, ensuring that the nylon bushing and the steel plate bracket 5 are on the same plane. The height of the connecting surface of the fixing post is lower than the height of the plane where the nylon bushing is located, ensuring more stable connection with the fixing hole of another nylon bushing shaft. The height of the back surface of the connecting surface of the fixing hole is lower than the height of the plane where the nylon bushing is located, ensuring more stable connection with the fixing post of another nylon bushing shaft. A fixing block 7 is arranged outside the nylon bushing, and a through hole 8 is arranged on the fixing block 7. After fixing the nylon bushing on the steel plate bracket 5 and passing a steel pipe through the nylon bushing shaft, bolts or self-tapping screws can be used to further fix the steel pipe through the through hole.

[0020] During use, the fixing posts 1 and fixing holes 2 of two nylon bushing shafts are fixedly connected respectively, that is, the fixing post 1 of one nylon bushing is passed through the fixing hole 2 of another nylon bushing. This connection position is an up-and-down overlapping structure, ensuring that the connected nylon bushing is circular. The diameter of the nylon bushing matches the diameter of the steel pipe used. According to different inner diameters, this nylon bushing can be used in combination with steel pipes with a diameter range of 20mm to 60mm (DN20, DN25, DN32, DN40, DN50). A limiting hole 6 matching the limiting portion 4 is arranged on the steel pipe bracket 5. The number of the limiting portion 4 and the limiting hole 6 is designed according to needs. After fixedly connecting the nylon bushing shafts, they are fixed on the steel pipe bracket 5 through the limiting portion 4 and the limiting hole 6. After passing the steel pipe through the nylon bushing shaft, bolts or self-tapping screws can be used to further fix the steel pipe through the fixing hole 2 and the through hole 8. If the nylon bushing is damaged, it is convenient to disassemble and replace. If one nylon bushing is damaged, one can be replaced, and the other can continue to be used in cooperation.

[0021] In summary, the present utility model can at least achieve the following beneficial effects:

[0022] 1. The nylon bushing designed by the present utility model has a self-lubricating function, small friction with the shaft, little damage to the zinc layer, and can prevent rust.

[0023] 2. The nylon bushing designed by the present utility model is of a split structure, convenient for disassembly and assembly, easy for maintenance and replacement, and can also be used for repairing, replacing, and substituting damaged copper bushings (the previous generation of bushings).

[0024] 3. The nylon bushing designed by the present utility model has a wide range of application fields, can be used in a variety of livestock and poultry breeding industries, is simple in design, convenient to install, and low in cost.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model, which is only used to illustrate the technical solution of the present utility model and is not used to limit the protection scope of the present utility model.
