Description
Technical field
The utility model relates to a kind of luggage castor.
Background technology
In the prior art, luggage castor is generally made up of link span and wheel body, wheel body is arranged on bracing frame bottom, bracing frame top is connected with link span by rotating shaft and realizes rotation, the upper end of rotating shaft on link span, is wherein provided with ball to make both rotations more smooth and easy by rivet between bracing frame and link span.But the luggage castor assembling of this structure is more difficult, needs to expend the more time in rivet process, and riveting quality is difficult to ensure; On the other hand, after long-term use, riveting portion is easily loosening, while causing wheel body to use, can rock, and affects in-use performance.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of luggage castor, is convenient to assembling, enhances productivity, and uses more reliable.
In order to solve the problems of the technologies described above, luggage castor of the present utility model, comprise link span and left and right wheel body, described left and right wheel body is arranged on respectively both sides, bracing frame bottom, is provided with column on link span, bracing frame top is provided with rotating shaft, support frame as described above and rotating shaft are that metal is one-body molded, and this rotating shaft is stretched in column, have annular positioning groove in rotating shaft, described column side is provided with the opening corresponding with this annular positioning groove, and a jump ring inserts in described opening and engages with annular positioning groove.
Support frame as described above bottom is provided with circular cavity, in this circular cavity, bearing is installed, and described bearing center is connected with bolster, and described left and right wheel body is installed on respectively bolster two ends.
Described circular cavity one side opening is provided with gulde edge, and opposite side edge of opening is provided with knock hole, in this knock hole, is provided with rivet, and described bearing outer rim is installed between described gulde edge and rivet.
Another kind as technique scheme improves, and support frame as described above bottom is provided with bolster, and described left and right wheel body is installed on respectively bolster two ends.
The beneficial effects of the utility model are: this luggage Castor structure is positioned at rotating shaft in the column on link span by jump ring, fitting process is easier, be conducive to improve the production efficiency of castor, and due to the constraint of column countershaft, the position location of jump ring can not be subject to the effect of horizontal direction power, be not easy to damage, use for a long time castor also can not rock, use more reliable; Bracing frame and rotating shaft are that metal is one-body molded, and structure is more firm, are beneficial to simplification product structure, and hardware is easy to surface treatment, and appearance is more attractive in appearance.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is decomposition texture schematic diagram of the present utility model;
Fig. 3 is the structural representation of bracing frame and rotating shaft.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, luggage castor of the present utility model, comprise link span 1 and left and right wheel body 2,3, described left and right wheel body 2,3 is arranged on respectively bracing frame 4 both sides, bottom, on link span 1, be provided with column 5, bracing frame 4 tops are provided with rotating shaft 6, support frame as described above 4 and rotating shaft 6 are that metal is one-body molded, this rotating shaft 6 is stretched in column 5, in rotating shaft 6, have annular positioning groove 7, described column 5 sides are provided with the opening corresponding with this annular positioning groove 78, one jump rings and insert in described opening and engage with annular positioning groove.This luggage Castor structure is positioned at rotating shaft in the column on link span by jump ring, fitting process is easier, be conducive to improve the production efficiency of castor, and due to the constraint of column countershaft, the position location of jump ring can not be subject to the effect of horizontal direction power, be not easy to damage, use for a long time castor also can not rock, use more reliable; Bracing frame and rotating shaft are that metal is one-body molded, and structure is more firm, are beneficial to simplification product structure, and hardware is easy to surface treatment, and appearance is more attractive in appearance.
