Wherein, which is between a full speed position, a deceleration position and a neutral.When the trussed shore
First 16 be in full speed position when, the driving fixture block 11 directly drive the protecgulum fan block 33, when the traction column cap 16 is in deceleration position
When setting, which directly drives fluted disc fan block 72, when the traction column cap 16 is in neutral, the driving fixture block
11 are detached from protecgulum fan block 33 and fluted disc fan block 72.
How to be used the following detailed description of child's tricycle forerunner wheel.
As shown in Figure 20 and Figure 21, which is on full speed position, under the action of compression spring 14, entirely
Driving fixture block 11 is slided into close to the side of protecgulum 3 so that before the fixture block protrusion 112 of a driving fixture block 11 is embedded into protecgulum 3
Between lid fan block 33.At this point, adjusting bracing wire 8 in the raw, draw ring 81 is stuck on the outer end end face of drive shaft tube 10.Work as child
When virgin pushes pedals 42, entire drive component 9S directly drives the protecgulum of protecgulum 3 to fan block 33 and is rotated, then, entire wheel body
As drive component 9S is travelled forward with identical speed.
As shown in Figure 22 and Figure 23, user pulls out the draw ring 81 for adjusting bracing wire 8, and draw ring 81 is snapped into first and is consolidated
Determine card column 43 first is fixed in skewed slot 431, as shown in Figure 2.During draw ring 81 pulls, the traction traction of bracing wire 8 is adjusted
Column cap 16, then, driving 15 synchronous drive of screw rod drive fixture block 11 to be slided towards the direction of power fluted disc 7,14 quilt of compression spring
It squeezes, deviates from between the protecgulum of protecgulum 3 fan block 33 until the fixture block of driving fixture block 11 protrudes 112, at this point, the traction column cap 16
In neutral.On this position, when user's pushes pedals 42, the power of entire drive component 9S is not transferred to
On wheel body.That is, when parent's hand-held bar carries out child, the foot of child can be put on pedal 42, pedal 42
Position will not be rotated with the rotation that forerunner takes turns, avoid that forerunner takes turns or pedal injures the foot of child, the foot times of child
Sense is comfortable.
As shown in Figure 24 to Figure 25, draw ring 81 is fixed from first in skewed slot 431 and is transferred to by user, is further continued for pulling out
The draw ring 81 of bracing wire 8 is adjusted, and draw ring 81 is snapped into the second of the second fixation card column 44 and is fixed in skewed slot 441.It is drawn in draw ring 81
In dynamic process, the traction traction column cap 16 of bracing wire 8 is adjusted, compression spring 14 is pressed further by, and driving fixture block 11 continues direction
The direction of power fluted disc 7 is slided, until the fixture block of driving fixture block 11 protrude 112 be embedded into power fluted disc 7 fluted disc fan block 72 it
Between, at this point, the traction column cap 16 is on deceleration position.When child's pushes pedals 42, entire drive component 9S directly drives
The fluted disc fan block 72 of power fluted disc 7 is rotated, and power is then sequentially delivered to the second transmission gear 6, first by power fluted disc 7
The rear cover tooth head 221 of transmission gear 5 and rear cover 2, the rotating speed of drive component 9S is reduced, and then, entire wheel body is with driving
Component 9S is travelled forward with lower speed.By adjusting rear cover tooth head 221, the first transmission gear 5 and the second transmission gear 6
Transmission parameter, such as diameter, the number of teeth etc., to obtain ideal reduction ratio, general 0.5-0.6 is proper.
It should be noted that during adjusting the traction of bracing wire 8, guide card of the adjusting bracing wire 8 in drive shaft tube 10
It is slided in mouth 102 so that the pulling for adjusting bracing wire 8 is more smooth.
As shown in figure 26, it is the another embodiment for the pedal that child's tricycle forerunner of the invention takes turns, in pedal song
It is set on axis there are three fixed card column, corresponds to full speed, idle running and the deceleration mode of child's tricycle forerunner wheel respectively.
It is second of embodiment of the child's tricycle forerunner wheel of the present invention, at this point, only as shown in Figure 27 to Figure 31
Part body is shown, including drive component 9SC, adjusting part 8SC and pedal assembly 4C.The structure of drive component 9SC with
A kind of upper embodiment is identical, and explanation is not repeated herein.
Adjusting part 8SC includes that an adjusting bracing wire 8C, an adjusting slider 17C and one adjust head 19C.Adjusting bracing wire 8C
It is connected with the traction column cap 16 and draws the traction column cap 16, the connection latch closure of an annular is equipped in the tail portion for adjusting bracing wire 8C
83C.Adjusting slider 17C includes the slide cavity 170C of a perforative rectangle, and the tail portion of slide cavity 170C is equipped with a chamber
The middle part of body connecting screw hole 171C, slide cavity 170C are equipped with a perforative cavity locking screw hole 172C, which connects spiral shell
Hole 171C connect latch closure 83C with this and is connected by a latch closure screw 18C.Adjusting head 19C runs through the cavity locking screw hole
172C, adjusting head 19C include an adjusting screw rod 191C, and the tail portion of adjusting screw rod 191C is equipped with a circular screw rod catch
The adjusting horizontal stripe 193C of 192C and a strip.
Pedal assembly 4C is located at the both ends of the drive shaft tube 10, and pedal assembly 4C includes a pedal crankshaft 41C
It is equipped with one first bent axle positioning screw hole 412C, one second bent axle positioning screw hole 413C with a pedal 42C, pedal crankshaft 41C
With a third bent axle positioning screw hole 414C.
The application method of the embodiment is described below.
As shown in figure 27, child's tricycle forerunner wheel is on Full-Speed mode, at this point, adjusting the adjusting screw rod of head 19C
191C through cavities locking screw hole 172C and the first bent axle positioning screw hole 412C.
When user needs to adjust the use pattern of forerunner's wheel, can unscrew and adjust head 19C so that adjust head 19C from
Deviate from cavity locking screw hole 172C and the first bent axle positioning screw hole 412C, then along pedal crankshaft 41C slidable adjustment sliding blocks
17C so that adjusting slider 17C is slided towards the direction of pedal 42C, until adjusting slider 17C reaches the second bent axle positioning screw hole
On the position of 413C.During adjusting slider 17C is slided, bracing wire 8A traction traction column caps 16 are adjusted, to change driving
The position of fixture block.Finally, head 19C will be adjusted to be screwed into cavity locking screw hole 172C and the second bent axle positioning screw hole 413C.In
It is that child's tricycle forerunner wheel is on idle mode.
When user needs to adjust the forerunner and take turns on deceleration mode, according to same mode of operation, will finally adjust
Head 19C is screwed into cavity locking screw hole 172C and third bent axle positioning screw hole 414C.
It should be noted that two groups of bent axle positioning screw holes can also be only set on pedal crankshaft 41C, it is corresponding empty respectively
Rotary-die type and deceleration mode.That is, the default mode of child's tricycle forerunner wheel is exactly Full-Speed mode, at this point, adjusting
Sliding block 17C is farthest at a distance from pedal 42C.
It can be suitble to the child of different age group with the ride mode of unrestricted choice tricycle due to the use of person, it is safe.
Not limited to this, any change or replacement expected without creative work should all cover the guarantor in the present invention
