Abstract
The utility model discloses a suitcase trundle of a turnup structure. The suitcase trundle of the turnup structure aims to solve the problem that buffering performance when an existing suitcase is matched with trundles in use is poor. The suitcase trundle of the turnup structure comprises a trundle shell and a trundle carrier arranged at the lower end of the trundle shell, the end face of the trundle shell is provided with a trundle connecting threaded hole and a suitcase connecting threaded hole, the trundle connecting threaded hole is fixed with a roller by penetrating through and being inserted into a connecting shaft rod, the suitcase connecting threaded hole is fixed with the suitcase through a matched screw, a contact edge of the trundle shell is of an arc-shaped chamfer turnup structure, the contact edge abuts against the contact end face of the suitcase, a plurality of reinforced ribs are arranged on the lower end face of the trundle shell, and the reinforced ribs and the trundle shell are formed in one-shot through injection molding. The suitcase trundle of the turnup structure can have good buffering effect when being used with the suitcase in match, therefore the service life of the trundle of the suitcase is prolonged, and the distance between the suitcase and the ground is reduced.
Description
Technical field
The utility model relates to a kind of castor, and being specifically related to is a kind of Castor for trunk or bag with turnup structure.
Background technology
The chest that carries in order to place article when the case and bag conduct is gone out is widely used, aspects such as the quality of its case and bag, flexible performance also more and more are subjected to the attention of customer and production firm, Castor for trunk or bag is as the auxiliary facility of case and bag, its quality and alerting ability also affect the in-use performance of case and bag to a great extent, existing Castor for trunk or bag is made up of castor shell and roller mostly, its castor shell mostly is planar structure greatly, and such structure is used at the cooperation case and bag and had problems such as cushion characteristic is poor, long-term use fractures easily.
Summary of the invention
In order to overcome the existing in prior technology deficiency, the purpose of this utility model just provides a kind of Castor for trunk or bag of turnup structure simple and reasonable for structure.
In order to reach above-mentioned design goal, the technical solution adopted in the utility model is as follows:
A kind of Castor for trunk or bag of turnup structure, comprise the castor shell and be installed in the roller of castor shell lower end, the end face of castor shell is provided with castor connecting thread hole and case and bag connecting thread hole, its castor connecting thread hole connects axostylus axostyle by interspersed one and roller forms fixing, case and bag connecting thread hole forms fixing by attachment screw and case and bag, the contact edge of described castor shell is a kind of turnup structure of arc angling, these contact edge and case and bag contact end face formation against.
Further, the lower surface of described castor shell also is provided with many reinforced ribs, and this reinforced rib is one-body molded by injection molding and castor shell.
The beneficial effects of the utility model: the engagement edge of castor shell and case and bag is designed to a kind of turnup structure of arc angling, and such design has increased the resiliency of case and bag and castor shell, lowers case and bag and wheel and ground-surface height.The lower surface of castor shell is provided with reinforced rib, thereby further strengthens the load-carrying intensity of castor.
Description of drawings
Fig. 1 is a whole structure scheme drawing of the present utility model.
The specific embodiment
