Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] See figure 1 , The universal wheel of the present invention comprises: an alloy wheel seat 1, a ball bearing is provided in the alloy wheel seat 1, and rollers 2 are connected to both sides of the ball bearing.

[0018] The alloy wheel base 1 is covered with a metal plate 3 .

[0019] The metal plate 3 is provided with a mounting hole 4 .

[0020] The present invention is composed of alloy wheel base 1, ball bearings, rollers 2 on both sides, and metal plate 3. The middle is alloy wheel base 1, and the inner circle is equipped with ball bearings. move and shake. The upper part of the alloy wheel seat 1 has a 4 cm hollow hole, which is connected to the metal plate 3, and the connection is designed as a hole, so that the steering is more portable and flexible; the metal plate 3 is an iron stamping part with 4 holes, and the function is to connect the chair.

Abstract

The invention relates to the technical field of wheels, in particular to a universal wheel. The universal wheel comprises an alloy wheel seat. A ball bearing is arranged in the alloy wheel seat, and rollers are connected at both sides of the ball bearing; the alloy wheel seat is sleeved with a metal flat plate; according to the invention, the alloy wheel seat and the ball bearing are combined, so the universal wheel has the advantages of low height, large load, insusceptibility to damage, smart and flexible rotation, strong loading ability, long service life, low noise, convenience for maintenance and the like. The universal wheel is also convenient to assemble and disassemble and has the characteristics of stable and reliable use. Therefore, the universal wheel has a good promotion and using value.

Description

[0001] technical field [0002] The invention relates to the technical field of wheels, in particular to a universal wheel. Background technique [0003] Universal wheels are used on chairs. The existing universal wheels are mainly made of PP (Polypropylene, Polypropylene) plastic, the surface treatment is not delicate, the material is hard, fragile, not wear-resistant, and inconvenient to replace. [0004] Because the supporting column of the existing universal wheel is long, the bearing force is not large enough, it is easy to crack, and the bottom plastic is easy to be scratched, resulting in deformation and unsightly appearance. resulting in a reduction in service life. [0005] In addition, the connection structure between the existing universal wheel and the wheel bottom is not well combined, and the wheel bottom is buckled on the bearing, which is not firm enough. [0006] Therefore, based on the defects of the above-mentioned existing universal wheels, it is necess...
