[0002] In the field of household commodities, round pipe products (such as clothes drying rod, support pipe fittings etc.) often need to bear large pressure or frequent friction, and the round pipe in the prior art is mostly of single material structure, such as ordinary carbon steel or plastic material. Such material is prone to the following problems in long-term use:

[0003] 1. Insufficient compression resistance: the traditional round pipe is prone to deformation or even breakage under heavy pressure, especially the lower half of the pipe body, which is directly in contact with the supporting surface, and the local stress concentration leads to accelerated wear.

[0004] 2. Poor wear resistance: the surface of the pipe body lacks effective protective layer, and friction or external force easily scratches the surface layer, affecting the appearance and service life.

[0005] Therefore, it is necessary to provide a new compression-resistant wear-resistant round pipe to solve the above technical problems. SUMMARY

[0006] To solve the above technical problems, the utility model provides a compression-resistant wear-resistant round pipe.

[0008] A pipe body, and

[0009] A plurality of steel balls arranged in the lower half of the pipe body;

[0010] The steel balls are embedded in the spherical grooves of the pipe body and symmetrically distributed along the axial direction of the pipe body, and one third of the spherical surface of the steel balls extends out of the pipe body;

[0011] A plurality of arc-shaped rubber beads are fixedly embedded in the upper half of the pipe body, and the two sides of the arc-shaped rubber beads extend to the pipe segment below the horizontal line α of the pipe body.

[0012] Preferably, the lowest spherical surface of the steel balls symmetrically distributed in the lower half of the pipe body is 1.2-3.0mm lower than the lowest pipe surface of the pipe body.

[0013] Preferably, the pipe body between adjacent arc-shaped rubber beads constitutes a flow channel.

[0014] Preferably, an excessive arc surface is arranged at the contact position of the arc-shaped rubber bead and the pipe body.

[0016] Preferably, the pipe body comprises a stainless steel inner layer, and a carbon steel layer with a composite structure is arranged on the stainless steel inner layer.

[0017] Preferably, an epoxy resin layer is coated on the carbon steel layer, and an RTV anti-flash coating layer is coated on the epoxy resin layer.

[0018] Compared with the related art, the anti-pressure and wear-resistant round pipe has the following beneficial effects:

[0019] The pipe body of the steel ball is arranged towards the ground, and since the lowest spherical surface of the steel ball is 1.2-3.0 mm apart from the lowest pipe surface of the pipe body, the steel ball plays a role of supporting the pipe body, forms dynamic support and disperses local pressure, avoids deformation of the pipe body and prolongs the service life, and the steel ball converts sliding friction between the pipe body and the contact surface into rolling friction, greatly reduces the wear rate, makes the pipe body more wear-resistant, and the equidistant arc-shaped rubber ridge of the upper half of the pipe body absorbs impact force through elastic deformation and enhances the anti-pressure capability.
