Description

Wheel and front-opening-cover luggage case with same

Technical Field

The utility model relates to a case and bag processing technology field specifically is a wheel and be equipped with the suitcase that uncaps before this wheel.

Background

The luggage case, also called a traveling case and a draw-bar box, is widely applied to daily life of people, and is generally used for carrying various articles for daily use when people go out for traveling or go on a business. Early luggage cases were made of wood or other heavy materials, and as air travel popularized, luggage cases tended to be made of lighter hard plastic or cloth, and luggage cases on the market were also generally standardized according to the size specifications of carry-on cases (carry-on luggage) and consignment cases (consignment luggage) of airlines (international air transport association), and most of the existing luggage cases were provided with pull rods and roller mechanisms, so that the pull rods and roller mechanisms could be pushed and pulled on flat ground more conveniently. People's trip is usually selected to remove convenient and the great pull rod suitcase of capacity now to carry clothing or daily necessities, and the combined mechanism who constitutes by pull rod and gyro wheel enables people's trip more swiftly convenient, and the gyro wheel device wherein has become the suitcase indispensable, a vital part naturally.

The existing roller devices are generally installed on two or four corners of the bottom of the luggage case, and the installation design usually includes two types, the corners of the first type of luggage case are designed to be inwardly concave, and the rollers are located in the concave. The corners of the second type of luggage case are in a protruding design, and the rollers are directly arranged at the corners of the case; for the first design mode, the concave design occupies the space inside the luggage case, so that the internal space is reduced, and the internal appearance is irregular, so that the space utilization rate is low; in the second design, although the protruding design does not cause the defects of the first luggage case, the case corner protrudes, so that the strength of the case corner is low, the case corner is not protected, the case corner is easy to crash in case of collision, and the service life of the luggage case is shortened.

Chinese patent (CN201820143208.2) discloses a roller mechanism for a luggage case, which is generally described as including a bracket, rollers, an outer wrap angle and an inner wrap angle, wherein the outer wrap angle is wrapped on three adjacent side surfaces forming the case angle, the inner wrap angle is wrapped and fixed on the inner side of the case angle at the lower end of the luggage case, the angle ejecting direction of the outer wrap angle faces the outer side of the luggage case, the outer wrap angle is fixedly connected with the inner wrap angle, the bracket is connected with the inner wrap angle, and the rollers are pivotally connected to the bracket.

The utilization rate of the internal space of the right-angle type trunk corner of the trunk is improved to a certain extent, the overall strength of the trunk is enhanced, the service life is prolonged, but the wrapping angle of the wrapping angle covers three adjacent side faces of the trunk body, so that the surface area of the trunk body is occupied, and the scheme has the improvement that for example, when the front cover-opening type trunk is used by the roller mechanism, the larger area of the front cover is occupied, the front cover cannot be opened to the size of the section of the whole trunk body, and the use of the space of the front cover-opening type trunk is influenced.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved
