The utility model is mainly composed of a main wheel (1), a left and a right bearing seats (2) of the main wheel, a fork (3), a seat cushion (4), pedals (5), wherein, the left and the right bearing seats (2) of the main wheel are respectively provided with an auxiliary small wheel supporting arm (6) which protrudes out of the lower rear side of the main wheel (1), and the end of each auxiliary small wheel supporting arm (6) is provided with an auxiliary small wheel (7). The utility model is a single-wheel cycle which is convenient for beginners to exercise.

Description

Unicycle

The utility model relates to a kind of unicycle.

Unicycle is mainly used in professional acrobatics at present, and common people can't not use through long-term career training, because its strong point has only a bit, particularly the balance of fore-and-aft direction grasp difficulty is very big.

The purpose of this utility model provides a kind of unicycle of the beginner's of being convenient to exercise.

To achieve these goals, technical solution of the present utility model is such: a kind of unicycle, mainly constitute by main wheel, left and right main axle bearing, fork youngster, seat cushion, stretcher, auxiliary steamboat supporting arm respectively is installed on the wherein left and right main axle bearing, stretch out at auxiliary steamboat supporting arm rear under the main wheel, is provided with auxiliary steamboat at the end of assisting the steamboat supporting arm.

Because in the above-mentioned technical solution, respectively be provided with an auxiliary steamboat in the both sides, rear of main wheel, make the beginner 3 together support can be arranged in car process, wherein two auxiliary steamboats play the supplemental support effect, having the low weight loose ground of beginner under the situation of supplemental support to find the equilibrium sensation of unicycle in process by bike, promptly the beginner has learned to ride unicycle under the situation of tripping and falling less.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is the constructional drawing of unicycle provided by the utility model.

Fig. 2 is the annexation enlarged drawing of main axle bearing and auxiliary steamboat supporting arm among Fig. 1.

Fig. 3 is the A-A cutaway view of Fig. 2.

Fig. 4 is the running condition figure of unicycle provided by the utility model when auxiliary steamboat resets.

Wherein: 1, main wheel; 2, main axle bearing; 3, fork youngster; 4, seat cushion; 5, stretcher; 6, auxiliary steamboat supporting arm; 7, auxiliary steamboat; 8, supporting arm fixed orifice; 9, supporting arm fixed groove; 10, fixing minor axis; 11 threaded sleeves; 12, outside thread; 13, fixation clip; 14, clamp nut; 15, the supporting arm fixed groove that resets.

As shown in Figure 1, the unicycle that the utility model provides mainly is made of main wheel 1, left and right main axle bearing 2, fork youngster 3, seat cushion 4, stretcher 5, auxiliary steamboat supporting arm 6 respectively is installed on the left and right main axle bearing 2, auxiliary steamboat supporting arm 6 stretches out toward 1 time rear of main wheel, is provided with auxiliary steamboat 7 at the end of assisting steamboat supporting arm 6.

For the auxiliary steamboat 7 that makes unicycle can be pulled down or load onto from main axle bearing 2 easily together with auxiliary steamboat supporting arm 6, as Fig. 2, shown in Figure 3, wherein the latter half of the fixation clip among Fig. 2 13 is omitted so that expose the structure of fixation clip 13 inboards, the utility model also is provided with supporting arm fixed orifice 8 and supporting arm fixed groove 9 on main axle bearing 2 on the main axle bearing 2, the head end of auxiliary steamboat supporting arm 6 has a fixing minor axis 10, fixedly minor axis 10 roughly becomes 90 degree angles mutually with auxiliary steamboat supporting arm 6, wherein fixedly short sleeve 10 is enclosed within the supporting arm fixed orifice 8 and auxiliary steamboat supporting arm 6 is pressed in the supporting arm fixed groove 9 near the part of head end, the outside of main axle bearing 2 is threaded sleeve pipe 11, the external cylindrical surface of threaded sleeve 11 is provided with outside thread 12, be set with fixation clip 13 on the threaded sleeve 11, the outside of fixation clip 13 is provided with clamp nut 14.

For the auxiliary steamboat that makes unicycle except dismounting easily, can also receive easily and be close to the reset mode of pitching youngster 3, as Fig. 2, shown in Figure 3, on main axle bearing 2 by supporting arm fixed orifice 8 up direction be provided with the supporting arm fixed groove 15 that resets.Therefore unicycle just can be adjusted into the auxiliary steamboat 7 shown in Figure 4 running condition that resets easily, the beginner is packed up assist steamboat 7 to use and do not affect the appearance this car is the same with common unicycle after association.
