Rubber wheel

Abstract

The invention discloses a rubber wheel. The rubber wheel comprises a bracket, a bearing, an inner rim and a brake piece; the bracket is provided with a shaft barrel; the bearing inner ring sleeves theshaft barrel; the inner rim sleeves on the bearing outer ring and is provided with brake convex teeth which are arranged around the rotation center of the inner rim at intervals; the brake piece canbe movably mounted on the bracket in a locking mode, and is provided with a brake structure capable of moving along with the brake piece to be inserted into or separated from the gap of the brake convex teeth. According to the rubber wheel, the bearing inner ring sleeves the shaft barrel, and the bearing outer ring sleeves the inner rim, so that the relative rotation of the inner rim and the bracket is realized, the rotation friction resistance is reduced through the bearing, and the rubber wheel rotates smoothly; the inner rim is provided with a circle of brake convex teeth, the brake piece is inserted into the brake convex teeth through the brake structure to realize braking of the rubber wheel, braking of the rubber wheel can be realized through matching of the inner rim and the brake piece, braking is realized without adding additional accessories, the structure and the size of the rubber wheel are simplified, the rubber wheel is lighter, and meanwhile, the cost of the rubber wheelis reduced.

Description

technical field [0001] The invention relates to the field of pulleys, in particular to a rubber wheel. Background technique [0002] In life and industrial production, in order to facilitate the movement of objects, rubber wheels are usually installed at the bottom of the object, so that the object can be easily pushed and the force required for handling is reduced; when the position of the object needs to be fixed, the rubber wheel needs to be locked, so the rubber wheel There are usually corresponding brake parts on the wheel. In order to cooperate with the brake parts, a part that cooperates with the brake parts is usually added to the rubber wheel, resulting in many structural parts of the rubber wheel. The structure is complicated and the installation is troublesome, which is not conducive to the rubber wheel development of portability. Contents of the invention [0003] The present invention aims to solve the above-mentioned technical problems at least to a certain ...

Problems solved by technology

[0002] In life and industrial production, in order to facilitate the movement of objects, rubber wheels are usually installed at the bottom of the object, so that the object can be easily pushed and the force required for handling is reduced; when the position of the object needs to be fixed, the rubber wheel needs to be locked, so the rubber wheel There are usually corresponding brake parts on the wheel. In order to cooperate with the brake parts, a part that cooperates with the brake parts is usually added to the rubber wheel, resulting in more structural parts of the rubber wheel, complex structure, troublesome installation, and is not conducive to the rubber wheel. development of portability
