Description

Technical Field

[0001] The utility model relates to a high-temperature carburized integrated stretching caster, specifically a caster which has no tracks and adopts a top wave disc, an upper wave disc, a manganese steel gasket and a movable wave disc to form a rotating component and has greater impact resistance. Background Art

[0002] In daily life, people often use trolleys, shopping carts, tool carts and other equipment that all use 360-degree freely rotating casters, and the connection between the casters and the tripods of the equipment is often welded. Since the steel balls of traditional casters are installed with square plate tracks, and the square plate is a welding connection component, it is easy to cause the square plate track to deform due to excessive high temperature during the welding process due to a long welding time, affecting the sliding of the steel balls inside. If the welding time is too short, false welding is easy to occur, which places too high technical requirements on welding workers, affecting production costs and efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a high-temperature carburized integrated stretching caster, whose ark has no track and adopts a top wave disc, an upper wave disc, a manganese steel gasket and a movable wave disc to form a rotating component, which has greater impact resistance and can effectively solve the problem of track deformation caused by welding.

[0004] The technical solution of the utility model is based on a top wave plate, an upper wave plate, a bracket, a manganese steel gasket, a steel ball, a movable wave plate, a square plate plate, a toothed wave plate, a flat-bottom rivet and a wheel, and is characterized in that the top wave plate and the upper and lower upper wave plates are superimposed and installed in the middle of the outer surface of the top surface of the bracket, an annular concave track is provided at the bottom of the top wave plate, and steel balls are arrayed in the annular concave track of the top wave plate, the manganese steel gasket and the upper and lower movable wave plates are superimposed and installed in the middle of the inner surface of the top surface of the bracket opposite to the upper and lower upper wave plates, an annular concave track is also provided on the top of the movable wave plate, and steel balls are also arrayed in the annular concave track of the movable wave plate, the square plate is installed on the top of the top wave plate, the toothed wave plate is installed on the bottom of the movable wave plate, and the flat-bottom rivet passes through the middle through holes of the square plate, the top wave plate, the upper wave plate, the top surface of the bracket, the manganese steel gasket, the movable wave plate and the toothed wave plate in turn from top to bottom to become the rotation center of the top wave plate, the upper wave plate and the movable wave plate.

[0005] The top wave plate, the upper wave plate and the movable wave plate described in the utility model are formed by integrally stamping the metal which has been subjected to high-temperature carburizing treatment, the manganese steel gasket is a manganese steel gasket which has been subjected to heat treatment, and the bracket is integrally formed by stretching.

[0006] The working principle of the utility model is that the square plate is separated and only serves as a component welded with the tripod. The track of the steel ball is designed on three components: the top wave plate, the movable wave plate and the tooth wave plate which are formed by integrally stamping the metal which has been subjected to high-temperature carburizing treatment. This avoids deformation of the steel ball track due to high welding temperature, thereby affecting the smoothness of the rotation of the caster, making the manufacturing more convenient and the yield rate higher.

[0007] The utility model has the advantages of simple structure, stable operation, flexible and smooth rotation, and can effectively solve the problem that the steel ball track is easily deformed during caster welding. At the same time, it has a firm structure and strong impact resistance, reduces production costs, and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
