Description
Technical field
This utility model is related to a kind of perambulator accessory, drives and brake gear before and after specifically a kind of perambulator.
Background technology
Perambulator species is various at present, such as two wheel bicycles, toy tricycle and four-wheel perambulator.For two wheel bicycles, due to weight
The heart is high, only adapts to school age population, and ride difficulty, rides also less safe, even if adding a pair of jockey pulleys of overturn-preventing, can not
Extensively in child, popularization is used.Toy tricycle only adapts to less child, and crank and driving wheel relative can not slide, easily hinder
And lower limbs of children, stability is poor and safety coefficient is not high.When child cycles, speed is slow, easily topple over, structure is simple and crude, security performance
Low, braking effect is poor, while also haveing the shortcomings that to improve child's limb coordination ability and improving physical ability.
By contrast, carriage is no matter from the crowd that is suitable for or stability and the security consideration from car body itself, all more
For ideal.But, existing four-wheel perambulator can only be that one direction is ridden forward, when some barriers are run into, if it is desired to after
Move back, can only be implementation of getting off, make troubles to user.
Utility model content
The purpose of this utility model is for the shortcoming for overcoming prior art to exist, there is provided a kind of simple structure, user
Just, can realize that the positive and negative twocouese of perambulator is driven and brake gear before and after driving a kind of perambulator ridden.
This utility model purpose is realized with the following methods：Drive and brake gear before and after a kind of perambulator, its feature exists
In：Which includes the fixed disk being connected with pushchair and the drive sleeve that is connected with power transmission shaft and movable sleeve, drive sleeve and movable sleeve
Installed in power transmission shaft surface and it is secured to, outside movable sleeve, is set with pulley, pulley is connected with fixed disk；
Described drive sleeve surface is provided with the rotating forward ratchet of direction and reversion ratchet, and ratchet surface is set with selection
Ring, selects avoiding hollow groove is offered on ring, rotates forward ratchet and reversion ratchet can pass through the avoiding hollow groove and be arranged on fixed disk endoporus
Draw-in groove connection, drive fixed disk rotate towards corresponding direction.
, in " " font, its base portion is hingedly mounted in drive sleeve for described rotating forward ratchet and reversion ratchet section.
Described drive sleeve surface is provided with turn, promotes rotating forward ratchet and reversion ratchet is upturned opening.
Described rotating forward ratchet and reversion ratchet interval ° are distributed in drive sleeve surface.
Described draw-in groove is some boss being arranged on fixed disk endoporus, forms draw-in groove between boss and fixed disk endoporus.
Described drive sleeve surface is also equipped with mask, and mask is docked with fixed disk.
The beneficial effects of the utility model are：1st, simple structure, low production cost improve the market competitiveness；2nd, using only
Special two-way ratchet and the cooperation for selecting ring, can cause the perambulator for installing this equipment while wheel function is met, both can be with
Ride forward, can ride backward again, lift the recreational of perambulator.
Description of the drawings
Fig. 1 is that this utility model assembles using effect figure with perambulator.
Fig. 2,3 are this utility model Standard figure.
Fig. 4,5 are this utility model structure general assembly drawing.
Fig. 6 is this utility model structure axial sectional view.
Fig. 7 is that this utility model structure rotates forward state radial cross-section.
Fig. 8 is this utility model structure inverted status radial cross-section.
Specific embodiment
Make concrete further instruction below in conjunction with the accompanying drawings to this utility model.Drive before and after a kind of perambulator and brake dress
Put, it is characterised in that：Which includes the fixed disk 2 being connected with pushchair 1 and the drive sleeve 4 that is connected with power transmission shaft 3 and movable sleeve
5, drive sleeve 4 and movable sleeve 5 are arranged on 3 surface of power transmission shaft and are secured to, and are set with pulley 6 outside movable sleeve 5, pulley 6 with it is solid
Price fixing 2 connects；
Described 4 surface of drive sleeve is provided with the rotating forward ratchet 41 of direction and reversion ratchet 42, ratchet surface suit
There is selection ring 7, select on ring 7, to offer avoiding hollow groove 71, rotate forward ratchet 41 and reversion ratchet 42 can pass through the avoiding hollow groove 71 and set
The draw-in groove 21 put on 2 endoporus of fixed disk connects, and drives fixed disk 2 to rotate towards corresponding direction.
, in figure six, its base portion is hingedly mounted on drive sleeve 4 for described rotating forward ratchet 41 and 42 section of reversion ratchet
On.
Described 4 surface of drive sleeve is provided with turn 43, promotes rotating forward ratchet 41 and reversion ratchet 42 to be upturned and beat
Open.
Described rotating forward ratchet 41 and reversion ratchet 42 are spaced 90 ° and are distributed in 4 surface of drive sleeve.
Described draw-in groove 21 is to be arranged on some boss 22 on 2 endoporus of fixed disk, shape between 2 endoporus of boss 22 and fixed disk
Into draw-in groove 21.
Described 4 surface of drive sleeve is also equipped with mask 8, and mask 8 is docked with fixed disk 2.
Operation principle：When riding, by riding, the drive disk assembly such as chain drives power transmission shaft 3 to rotate to user.When user to
Before when riding, as shown in fig. 7, power transmission shaft drives drive sleeve 4 to travel forward so that rotate forward ratchet 41 from the avoiding hollow groove for selecting ring 7
Place stretches out, and is buckled on draw-in groove 21, and the power of drive sleeve is delivered on fixed disk 2 by rotating forward ratchet 41, fixed disk band motor-car
Wheel travels forward.
When user is in sliding state, drive sleeve is motionless, and selects ring to rotate so that avoiding hollow groove thereon and rotating forward spine
Tooth 41 misplaces, and will rotate forward ratchet 41 and reversion ratchet 42 is accommodated in rotating ring, cut off the power connector of ratchet and fixed disk, this
When perambulator in idling slide state.
As described in Figure 8, when user needs reversely to ride, power transmission shaft reversion, power transmission shaft is driven to drive drive sleeve with foot-operated
Reversion so that reversely ratchet 42 is ejected from avoiding hollow groove 71, is buckled on draw-in groove 21, the power of drive sleeve pass through reverse ratchet 42
It is delivered on fixed disk 2, fixed disk band motor car wheel is moved backward.Therefore, compared with conventional art, the structure in this case is being realized
While traditional structure wheel function, additionally it is possible to which unrestricted choice drives forwards perambulator and rides, also may be selected to ride backward, so as to carry
The feature and enjoyment of riding of perambulator are risen, therefore use can be widely popularized.
Ultimate principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Simply illustrate principle of the present utility model, on the premise of without departing from this utility model spirit and scope, this utility model is also
