Abstract
The utility model proposes a kind of castor, comprising the inner ring by connecting successively from inside to outside, centre circle and outer ring, be also connected by pillar stiffener between described inner ring with described outer ring, described inner ring, described pillar stiffener and described outer ring are one-body molded.The utility model by increasing pillar stiffener between inner ring and outer ring, and inner ring, pillar stiffener and outer ring are one-body molded, and such design can add the load-carrying capacity of castor, improves the in-use performance of castor.
Description
Technical field
The utility model relates to castor technical field, refers to a kind of castor especially.
Background technology
Existing castor comprises inner ring, centre circle and outer ring, the material of inner ring is nylon, the material of centre circle is rubber, the material of outer ring is nylon, castor manufacture craft is bonded together in inner ring, centre circle and outer ring by lining cement, and such castor load-carrying capacity is low, easily damages, service life is short, thus reduces the in-use performance of castor on the whole.
Therefore, must make improvements for above-mentioned defect.
Utility model content
The utility model proposes a kind of castor, solve the problem of the in-use performance difference of castor in prior art.
The technical solution of the utility model is achieved in that
A kind of castor, comprising the inner ring by connecting successively from inside to outside, centre circle and outer ring, being also connected by pillar stiffener between described inner ring with described outer ring, described inner ring, described pillar stiffener and described outer ring are one-body molded.
Further, described pillar stiffener is at least three that are uniformly distributed between described inner ring and described outer ring.
Further, described pillar stiffener is four, and its angle of inclination is 45 °.
Further, the material of described inner ring, described pillar stiffener and described outer ring is polypropylene, and the material of described centre circle is thermoplastic rubber.
Further, described inner ring is provided with castor connecting bore.
Enforcement the beneficial effects of the utility model have:
The utility model by increasing pillar stiffener between inner ring and outer ring, and inner ring, pillar stiffener and outer ring are one-body molded, and such design can add the load-carrying capacity of castor, improves the in-use performance of castor.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the perspective view of a kind of castor of the utility model embodiment;
Fig. 2 is the side-looking structural representation of a kind of castor of the utility model embodiment;
Fig. 3 is the side-looking structural representation not with centre circle of a kind of castor of the utility model embodiment;
Figure number and explanation thereof:
1, outer ring; 2, centre circle; 3, inner ring; 4, castor connecting bore; 5, pillar stiffener.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Referring to figs. 1 through Fig. 3, a kind of castor that the utility model provides, being comprised the inner ring 3 by connecting successively from inside to outside, centre circle 2 and outer ring 1, being also connected by pillar stiffener 5 between inner ring 3 with outer ring 1, and inner ring 3, pillar stiffener 5 and outer ring 1 are one-body molded.Inner ring 3, pillar stiffener 5 and outer ring 1 adopt and one-body moldedly can reduce manufacture craft, can ensure the stability connected, can also be increased the load-carrying capacity of outer ring 1, namely increase the load-carrying capacity of castor by pillar stiffener 5, improve the in-use performance of castor.
Pillar stiffener 5 is at least three that are uniformly distributed between inner ring 3 and outer ring 1.Castor uniform force can be ensured by well-distributed pillar stiffener 5, improve the in-use performance of castor.
Pillar stiffener 5 is four, and its angle of inclination is 45 °, can ensure that castor possesses better elastic performance by the angle of inclination be provided with, and improves the load-carrying capacity of castor.
The material of inner ring 3, pillar stiffener 5 and outer ring 1 is polypropylene, and the material of centre circle 2 is thermoplastic rubber.The oil resistant of castor, wear resisting property and elasticity can be improved by polypropylene and thermoplastic rubber, the technical program be first after one-body molded to inner ring 3, pillar stiffener 5 and outer ring 1, again thermoplastic rubber is injected between inner ring 3 and outer ring 1 and forms centre circle 2, such structural bearing performance and good springiness.
Inner ring 1 is provided with castor connecting bore 4, can be connected by castor connecting bore 4 with castor.
In sum, the utility model by increasing pillar stiffener between inner ring and outer ring, and inner ring, pillar stiffener and outer ring are one-body molded, and such design can add the load-carrying capacity of castor, improves the in-use performance of castor.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
