Problems solved by technology

[0002] In snowy days, there is snow on the road and it melts and freezes, making ordinary bicycle tires very easy to slip, making it impossible to move forward, and even causing traffic hazards
However, the current snowmobiles are too bulky in daily life, inconvenient to ride, and have low use value.

Embodiment Construction

[0011] exist figure 1 and figure 2 In the schematic diagram of the present invention shown, the middle part of the main tire 1 is plugged with the wheel shaft 8, and the both sides of the main tire are respectively provided with auxiliary tires, and the two auxiliary tires are respectively inserted on the wheel shaft. The two ends of the axle are respectively connected with the fixing part 9, the cross section of the fixing part is in the shape of a five-pointed star, and the fixing part and the bracket 6 are connected by buckles 4, and each bracket is respectively in the shape of a cross. Fixedly connect the plate tire 7 at the free end of the support. The two ends of the wheel shaft are sequentially inserted into the limiting groove 5 that can rotate with the wheel shaft, the rotating groove that can rotate with the wheel shaft or independently, the rotating bearing and the knob, and the knob 2 and the rotating groove 3 are connected by screws. To control the rotation of ...

Abstract

Provided is a dual-purpose tire. An axle is inserted in the middle of a main tire body, vice tire bodies are arranged at the two sides of the main tire body separately and are inserted in the axle, the two ends of the axle are connected with a fixing part separately, the cross section of the fixing part is in a five-pointed star shape, the fixing part is connected with supports through buckles, each support is in an intersection shape, the free ends of the supports are fixedly connected with plate-shaped tires, and the two ends of the axle are inserted into limit grooves, rotation grooves, rotation bearings and rotary knobs in sequence from interior to exterior, wherein the limit grooves can rotate along with the axle, and the rotation grooves can rotate along with the axle or rotate solely; the rotary knobs are connected with the rotation grooves through screws to control the rotation grooves to rotate, and through a series of transmission devices, the vice tire bodies are controlledto spread or retract. The dual-purpose tire can be used during both snowy days and normal weather conditions; by the adoption of the dual-purpose tire, during the snowy days, accumulated snow exists on roads, ice melts, slippage does not easily occur, advance is convenient, and the dual-purpose tire is convenient to use and higher in safety.

Description

technical field [0001] The invention relates to the field of bicycle accessories. Background technique [0002] In snowy days, there is snow on the road and it melts and freezes, making ordinary bicycle tires very easy to slip, making it impossible to move forward, and even causing traffic hazards. And present snow bicycle is too bulky again in ordinary life, is inconvenient to ride, and use value is low. Contents of the invention [0003] The purpose of the present invention is to provide a kind of dual-purpose tire that can be used in both snowy days and normal weather, and there is snow on the road in snowy days that melts and freezes, is not easy to slip, is easy to move forward, is convenient to use and has higher safety. [0004] The invention mainly includes main tires, knobs, rotating grooves, buckles, limiting grooves, brackets, plate tires, wheel axles and fixing parts. [0005] Wherein, a wheel shaft is plugged in the middle part of the main tire, auxiliary ti...
