Abstract
The utility model relates to an anti-slip device for a bicycle tyre, which is characterized in that the utility model is a section of concave groove body with circular arc shape, and the outer side surface of the concave groove body is provided with a plurality of protrusions. The shape of the cross-section of the concave groove body forms like a C, and the concave groove body is buckled and pressed on the tyre cover of the tyre in the state of insufficient tyre deflation or inflation. When the tyre is inflated, the tyre cover and the concave groove body are squeezed mutually to make the groove body fix on the tyre cover of the tyre under the action of inner tube gas pressure. The device has simple and quick installation and disassembly process, the bicycle running on a snow and ice road face normally can be guaranteed, and the utility model prevents the injury of people from falling.
Description
The utility model relates to a kind of bike tyre anti-skid device.
At present, the cover tire of commercially available its tire of bicycle (no ice and snow) on normal road surface still has rideability preferably; But on ice and snow road, the antiskid capability of tire but can not get guaranteeing, thus bicycle in motion, during brake and the cyclist make in the course of action of bicycle up and down, bicycle is very easily toppled over and is caused cyclist's tumble injury.
The purpose of this utility model provides a kind of bike tyre anti-skid device, and it can make the cover tire of bicycle anti-skidding on ice and snow road, guarantee bicycle cruising on ice and snow road, and the installing/dismounting process is easy, rapid.
The purpose of this utility model is achieved in that provides a kind of bike tyre anti-skid device, it is characterized in that: it is the groove body of one section circular shape, is provided with a plurality of projections at the outer surface of groove body; The cross sectional shape of the groove of described groove body is " C " shape, it bleed a tire or the state of air pressure deficiency under withhold on the cover tire at tire.Cover tire is fixed on the cover tire of tire the groove body with groove body mutual extrusion under the inner tube of a tyre gas pressure behind the inflation of tire.
Owing to adopted such scheme, rely on and fix described antiskid device for tyre on the tire, improved cover tire antiskid capability on ice and snow road of bicycle greatly, the installation of anti-skid device and dismounting are that the air pressure adjustment by tire realizes, except that using Floor Pump, do not need any instrument, thereby installation and unloading process are very easy, rapid; Behind this anti-skid device of mounting of tyre, not only can cruising, and do not influence bicycle brake mechanism; After melting of ice and snow, this device can be taken off from bike tyre, thereby not destroy the road surface.
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 1 is the constructional drawing of the utility model preferred embodiment;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is embodiment illustrated in fig. 1 and assembly drowing bike tyre;
Fig. 4 is the B-B cutaway view of Fig. 3.
Embodiment as shown in Figure 1, it is the groove body 1 of one section circular shape, outer surface at groove body 1 is provided with a plurality of projections 2, the arc radius of groove body 1 is identical or roughly the same with the radius of the cover tire of tire 3, projection 2 combines with groove body 1, the shape of projection 2 be coniform, also can make pyramid-shaped, projection 2 is hard, for example adopts iron and steel, pottery, has a rigid plastic etc. of anti-fragility in the winter time.
As shown in Figure 2, the shape of cross section of the groove 12 of groove body 1 is " C " shape, and projection 2 combines with groove body 1, and the manufactured materials of projection 2 can identical with the material of groove body 1, also can be different.
As shown in Figure 3, the groove body 1 of anti-skid device is withheld on the cover tire 3 that is fixed on tire, and the curved edge of groove body 1 is not carried out lid with the ring-shaped brake face of metal rim, thereby does not influence the braking mechanism action of bicycle.
As shown in Figure 4, the groove body 1 of antiskid device for tyre and cover tire 3 mutual extrusion under the inner tube of a tyre 4 gas pressures of tire are securely fixed on the cover tire 3 of tire groove body 1.
