Wherein, which is between a neutral, a deceleration position and a full speed position,

When the adjustment gear 10 is in neutral, which is retracted in the guidance notch 84；When the tune When section gear 10 is in deceleration position, which slides in and out along guidance notch 84, and the first of the driving arm 12 Locking prominent 124 is caught in the guidance strip 412；When the adjustment gear 10 is in full speed position, the driving arm 12 along Guidance notch 84 continues to slide out, and second locking prominent 127 is caught in the internal tooth head 211.Hereinafter will further it be said It is bright.

The usage mode of the child's tricycle front-wheel is illustrated below.

As shown in Figure 18 to Figure 20, user rotates adjustment gear 10, so that the arrow 105 in adjustment gear 10 refers to To the first cue mark 33, the adjusting rod 122 of driving arm 12 is located at the inner terminal of guiding arc slot 93, and driving arm 12 is retracted in It guides in notch 84, at this point, the first locking prominent 124 is not caught in guidance strip 412, the second locking protrudes 127 also not It is caught in internal tooth head 211.At this point, child's foot pedal 42 is forward, since the first locking prominent 124 is detached from guidance strip 412, the Two lockings prominent 127 are detached from internal tooth head 211, so, drive substrate 8, adjustment gear 10 and adjusting 9 synchronous idle of fluted disc, this When, child's tricycle can not move ahead, and parent can also freely carry out tricycle, and pedal 42 will not get to the foot of child.

As shown in Figure 21 to Figure 23, user continues to rotate adjustment gear 10, so that the arrow in adjustment gear 10 105 are directed toward the second cue mark 34, and the adjusting rod 122 of driving arm 12 slides into the middle part of guiding arc slot 93, driving arm 12 It slides in and out along guidance notch 84, is guided in strip 412 until the first locking prominent 124 is caught in, and the second locking prominent 127 It is not caught in internal tooth head 211 yet.At this point, child's foot pedal 42 is forward, since the first locking prominent 124 is caught in guidance strip 412 It is interior, and the second locking prominent 127 is still detached from internal tooth head 211, so, drive substrate 8, adjustment gear 10 adjust fluted disc 9 and pass Rotating ring 4 rotates synchronously, and the rotation of transmission ring 4 will drive the first transmission gear 5 and the second transmission gear 6, and then power is transmitted to The ring gear 21 of rear cover 2, then, entire rear cover 2 rotate forward together with front cover 3.When the anti-pedal 42 of child backward when, it is whole A rear cover 2 can also rotate backward together with front cover 3.Outer gear ring 41,5 and of the first transmission gear by adjusting transmission ring 4 The transmission parameter, such as diameter, the number of teeth etc. of second transmission gear 6, to obtain ideal reduction ratio, general 0.5-0.6 compares Properly.

As shown in Figure 24 to Figure 26, user continues to rotate adjustment gear 10, so that the arrow in adjustment gear 10 105 are directed toward third cue mark 35, and the adjusting rod 122 of driving arm 12 slides into the outermost end of guiding arc slot 93, driving arm 12 continue to slide out along guidance notch 84, until the second locking prominent 127 is caught in internal tooth head 211, at this point, the first locking Prominent 124 are still stuck in guidance strip 412.At this point, child's foot pedal 42 is forward, be caught in due to the second locking prominent 127 in Tooth head 211 is interior and the first locking prominent 124 is still stuck in guidance strip 412, so, drive substrate 8, is adjusted adjustment gear 10 Fluted disc 9, transmission ring 4 and rear cover 2 rotate synchronously, at this time the ride mode and Full-Speed mode of as common child's tricycle.

No matter which kind of ride mode in user's three of the above, finally locking nut 11 must all be screwed, so that adjusting The relative position for saving gear 10 and adjusting fluted disc 9 is locked.

It is described below and how to adjust rotation adjustment gear 10, as shown in Fig. 1 and Figure 16, user can from watch window 32 To learn the direction of the arrow 105 in adjustment gear 10.Then, the plectrum bayonet in adjustment gear 10 is withstood using screwdriver 103, and rotate screwdriver and arrow 105 is made to be directed toward the corresponding cue mark of mode needed.Finally, being locked using box spanner Tight locking nut 11 locks adjustment gear 10 and the relative position for adjusting fluted disc 9 so that locking nut 11 compresses adjustment gear 10 Extremely.When needing to adjust other ride modes, locking nut 11 is unscrewed again, is repeated the above process.

It is described below and how to use the swing arm unit 7.When installing transmission ring 4, first swing arm unit 7 is pushed aside outward, so Transmission ring 4 is put into rear cover 2 afterwards, and the outer gear ring 41 of transmission ring 4 is meshed with each first transmission gear 5.Most Afterwards, swing arm unit 7 is discharged, under the action of swing arm torsional spring 74, so that swing arm main body 71 has inwardly rotation, swing arm cam 73 is tight Press limited ring groove 421.In the rotation process of transmission ring 4, swing arm cam 73 presses limited ring groove 421 always, and stability of rotation can It leans on.

As shown in figure 27, user also can be used the tool 13 in figure and come to the plectrum bayonet 103 in adjustment gear 10 It is operated, which includes the operation horizontal stripe 131 of a strip, is equipped with a pair of of strip on the head of operation horizontal stripe 131 Engaging column cap 132, engage to be equipped between column cap 132 and one screw arc slot 133, facilitate the operation of box spanner.In operation horizontal stripe 131 tail portion is equipped with a rocking handle 134.In use, a pair of engaging column cap 132 is directly snapped onto the plectrum card in adjustment gear 10 In mouthfuls 103, then rotation crank 134, so that tool 13 rotates, until arrow 105 is directed toward the cue mark needed. Finally, the sleeve of box spanner is inserted into from screwing between arc slot 133, locking nut 11 is screwed.

It is second of embodiment of child's tricycle front-wheel of the invention as shown in Figure 28 to Figure 37.With the first reality It applies unlike mode, adjustment gear 10 is conditioned component 10S substitution.

One first positioning jack 85A is equipped in the circumferential direction of the fan board shaft bar 822A of drive substrate 8A, one second positioning is inserted A hole 86A and third positioning jack 87A, and the first positioning jack 85A, the second positioning jack 86A and third positioning jack 87A Position is corresponding with the position of the first cue mark 33, the second cue mark 34 and third cue mark 35 respectively.
