Abstract
The utility model discloses a deflection mechanism for putting away a baby carriage front wheel set. The mechanism comprises the front wheel set arranged on a baby carriage framework, the upper end of the front wheel set is provided with a middle shaft so as to be assembled to the front end of the baby carriage framework, the upper end of the middle shaft is provided with a guide assembly, the guide assembly can move downwards along with the middle shaft to abut against the front end of the baby carriage framework when the baby carriage framework moves to be in a folded state, and accordingly the middle shaft is guided to drive the front wheel set to deflect at a certain angle. According to the deflection mechanism for putting away the baby carriage front wheel set, when the baby carriage framework is put away, the front wheel set can automatically deflect at a certain angle, so that the folded state of the three-wheel baby carriage framework is more compact and the three-wheel baby carriage framework is convenient to fold. Besides, by means of the design that a positioning rod is directly pulled through quick release joints, the front wheel set can be quickly disassembled and assembled. By means of a front push-pull positioning rod base and a rear push-pull positioning rod base of the control end, directed locking and release of direct unlocking of the front wheel set become easier.
Description
Technical field
The utility model relates to a kind of baby-carrier fore wheel group deflection mechanism that returns the vehicle to the garage and knock off, particularly a kind of front wheels baby-carrier fore wheel group of beat one angle deflection mechanism that returns the vehicle to the garage and knock off automatically in the time that skeleton folds.
Background technology
The virgin hand barrow of baby is for for the designed vehicle of child, and for making go-cart there is the less volume of timber, in order to transporting or placing, therefore, its three wheeled stroller skeleton, except launching use state, still can utilize the four-bar linkage structure principle of each rod member pivot joint, makes each rod member pivotable mutually, reach the folding of drawing close of three wheeled stroller skeleton, reduce space shared when transporting or collecting with actv., wherein in three-wheel vehicle part, be commonly called as the car of jogging (Jogger), as its name suggests, it is mainly used to operator in the time jogging, promote this three-wheel vehicle moves simultaneously, because three-wheel vehicle is under use state, it is fast that more general perambulator moving velocity is wanted, therefore, for keeping its rectilinearity moving and handling, more than normally used wheel diameter approximately 16 English inch, if these front wheels increase the handling of promotion and are wheels capable of free rotation, when carrying out skeleton while folding, though wheels can turn to before in the process of returning the vehicle to the garage and knock off, but still make front-wheel straight line forward because of unsettled when folding, so that be subject to the restriction of back skeleton or seat cloth, folding process is interfered, operator is just continued to fold skeleton after must starting to allow front wheels deflection 90 spend, the inconvenience that folding process is suitable.
Utility model content

The specific embodiment
As shown in Figure 1, the baby-carrier fore wheel group of the present utility model deflection mechanism that returns the vehicle to the garage and knock off, in order to be installed in the front wheels 7 of a three wheeled stroller skeleton 10.Described front wheels 7 can comprise a front fork assembly 73 and a wheel 74, and front fork assembly 73 is connected in the lower end of axis 71, and wheel 74 is coupling in front fork assembly 73.
The deflection mechanism embodiment that returns the vehicle to the garage and knock off of baby-carrier fore wheel group as shown in Figure 2, an axis 71 is established for forward foot in a step support 1 front end that is connected to three wheeled stroller skeleton 10 in the upper end that is included in front wheels 7, and the upper end of axis 71 sets firmly an arrangement for guiding 72; In the time of folding state 200 that three wheeled stroller skeleton 10 is passed to shown in Fig. 7 from the deployed condition 100 shown in Fig. 1, the gravity of self can be unsettled by front wheels 7 time, arrangement for guiding 72 is glided with axis 71 and with the relative position of front end of three wheeled stroller skeleton 10 produce slidably against, wheels 7 beat one angles before thereby guiding axis 71 drives, make the folding state 200 of three wheeled stroller skeleton 10 more tight.
As shown in Fig. 1 or Fig. 5, at the front end of three wheeled stroller skeleton 10, for example still can weld or affixed one axis 71 of seat 11 for wheels 7 upper ends before being coupling that are coupling at forward foot in a step support 1, therefore front wheels 7 must freely be turned round in the front end of three wheeled stroller skeleton 10, comply with flexibly the turning of perambulator and advance.
As Fig. 2, apply front wheels 7 of the present utility model and can pull down and rapid-assembling from three wheeled stroller skeleton 10, and can select orientation or freely turn round.For this reason, can set up a detent mechanism 8 at the seat 11 that is coupling, in the time of clip, make axis 71 rotate and cannot depart from respect to the seat 11 that is coupling; In the time removing clip, allow that axis 71 departs from the seat 11 that is coupling.
The detent mechanism 8 of the present embodiment comprises a slide 81, a positioning rod seat 82 and a positioning rod 83.Wherein slide 81 can interlocking in the seat 11 that is coupling, which is provided with a slide slotted eye 810 and therefrom pass through for axis 71 and arrangement for guiding 72.
In addition, be still provided with a pole socket slotted eye 822 and a positioning rod chute 823 in location on pole socket 82, wherein pole socket slotted eye 822 can hold axis 71 and arrangement for guiding 72 therefrom passes through, and the direction of radius stay chute 823 lies in the position to quasi-middle shaft 71.
Radius stay 83 telescopicallies are installed in radius stay chute 823, and while stretching out, its end can be touched axis 71 and produces and prevent that axis 71 from departing from the effect of the seat 11 that is coupling.Better one, radius stay 83 can utilize an elastic parts 830 apply bias voltage and keep stretching out towards this axis 71.
For the orientating function of front wheels 7 is provided, on axis 71, can establishes a knock hole 710 and insert for radius stay 83.By this, when location pole socket 82 is while moving to primary importance, radius stay 83 inserts knock hole 710 because stretched out by elastic parts 830 bias voltages, makes axis 71 therefore cannot rotate and makes front wheels 7 keep directed.
When location pole socket 82 is while moving to the second place, even if radius stay 83, because stretched out by elastic parts 830 bias voltages, but because the second place is far away apart from axis 71, therefore can not insert knock hole 710, and can only make axis 71 not glide and depart from the seat 11 that is coupling.
As shown in Figures 3 to 5, the arrangement for guiding 72 of the present embodiment is at least towards dividing into an inclined-plane 720.By this, be passed in the process of folding state 200 at three wheeled stroller skeleton 10, front wheels 7 drive axis 71 to glide together with arrangement for guiding 72 gravity because of unsettled mat self, to make inclined-plane 720 slidably against radius stay 83, thus automatic beat one angle of wheels 7 before axis 71 is driven.
Better one, the radius stay 83 of the present embodiment can connect one again and release soon 831,831 one end that are revealed in location pole socket 82 are released in order soon, allow user release soon 831 and radius stay 83 contractings are moved back by pulling, and allow axis 71 can depart from be immediately coupling seat 11 and pull down front wheels 7 of down slippage.
Contrast Fig. 6 and Fig. 7 are known: if lack the baby-carrier fore wheel group of the present utility model deflection mechanism that returns the vehicle to the garage and knock off, front-wheel is because of beat automatically, when three wheeled stroller skeleton 10 returns the vehicle to the garage and knock off, may push up three wheeled stroller skeleton 10 other member and cannot folding to state the most closely.If be added with the baby-carrier fore wheel group of the present utility model deflection mechanism that returns the vehicle to the garage and knock off, can in the time returning the vehicle to the garage and knock off, make the automatic beat of wheel, allow three wheeled stroller skeleton 10 reach folding state the most closely.
