The utility model provides a truckle is particularly suitable for installing and uses on boxes such as suitcase, toolbox.
Description
Technical Field
The utility model relates to a daily life articles for use technique especially relates to a technique of thin wall hollow truckle.
Background
The casters used on the existing luggage cases and tool cases are all provided with wheel shafts which are generally solid metal shafts, so that the material cost is higher and the weight is heavier. In addition, the joint of the wheel shaft and the wheel hub is easy to be wound with wire sundries, and the rolling of the caster is influenced.
SUMMERY OF THE UTILITY MODEL
To the defect that exists among the above-mentioned prior art, the utility model aims to solve the technical problem that a thin wall hollow caster that weight is little, and material cost is low, difficult winding line class debris is provided.
In order to solve the technical problem, the utility model provides a thin wall hollow caster, its characterized in that: comprises a wheel seat and a wheel carrier fixed on the wheel seat;
the wheel carrier consists of a circular wheel ring and an L-shaped fixing plate, the fixing plate is fixedly connected with the wheel ring, a wheel groove is formed between the fixing plate and the outer ring surface of the wheel ring, the wheel groove is an arc groove which is communicated in the circumferential direction of the wheel ring, the arc center of the wheel groove is superposed with the ring center of the wheel ring, and the groove wall of the wheel groove facing to the arc center side is formed by the outer ring surface of the wheel ring;
the outer ring surface of the wheel ring is coaxially sleeved with a circular hub, the hub can rotate relative to the wheel ring, the outer ring surface of the hub is coaxially sleeved with a circular tire, the hub and the tire are in tight fit, and the hub and the tire pass through the wheel groove in a clearance fit manner;
the fixed plate is fixed on the wheel seat, and the fixed plate is provided with a limit pin for limiting the wheel hub and the tire to be separated from the wheel groove.
Furthermore, a plurality of rotatable rollers are arranged on the inner circle of the hub, the rollers are symmetrically distributed around the ring center of the hub, the rotation axis of each roller is parallel to the ring center axis of the hub, and each roller is abutted against the outer ring surface of the wheel ring and the inner ring surface of the hub in a rolling fit mode.
The utility model provides a thin wall hollow castor utilizes the torus to replace traditional shaft to support as the main part, and its weight and material cost all will be less than traditional shaft, can alleviate the weight of truckle, because the diameter of torus is great, also is difficult for winding line class debris moreover.
