Description
Technical field
The present invention relates to a kind of wheel rotary positioning apparatus more particularly to one kind except that can set orientation or freely turn to,
Can also it is easy to disassemble or assembling perambulator front-wheel rotary positioning apparatus.
Background technology
Perambulator mainly by vehicle frame and is hubbed at a plurality of wheels of vehicle frame bottom and is formed, and wherein vehicle frame can be knitted with softness
Cloth coats, and is taken for infant, and vehicle frame is provided with handle, to allow parent that can grip handle, vehicle frame is made to be pushed away by wheel
It is dynamic to advance；Current visible perambulator species is comparable more, is distinguished with body frame structure for automotive, can be divided into it is foldable and not foldable,
It is distinguished with seat, there is single seat and twin seat, distinguished with function, there is GENERAL TYPE and a sports type, distinguished with wheel,
There are three wheel-type and four wheel-type etc., for kinematic pram（The Patent Case of the U.S. the 6196572nd, No. 5876309 patent
Case and No. 5536033 Patent Case）, when kinematic pram offer parent goes out to jog, infant is allowed to ride in perambulator,
Parent can push perambulator and move together, and usual kinematic pram uses the design of three wheel-type for the convenience of manipulation,
That is, front-wheel sets one, trailing wheel sets two, due to the use of person under motion state（When jogging）, what perambulator was pushed into
Speed is more quicker than what ordinary circumstance was got off, therefore causes front-wheel accidentally suddenly significantly for pavement behavior or user is avoided to exert a force
The danger for turning to and perambulator being caused to topple over, wherein front-wheel towards the direction of perambulator advance and can not all must turn with trailing wheel
To ensure to ride on the safety of infant in perambulator.
No. 506372 Patent Case of TaiWan, China Announcement Number, discloses that a kind of front-wheel of three wheeled stroller is rotatable to be determined
Bit architecture, since the location structure system of the case is installed on the front of fore-stock so that when promoting perambulator, easily accidentally touch
To barrier, and cause unexpected release braking structure, in turn resulting in front-wheel improperly rotates or position, can with causing danger
It can property.
Therefore, it is necessary to invent one kind except that can set orientation or freely turn to, moreover it is possible to it is easy to disassemble or assemble can be real
Baby's vehicle control of existing directional rotating solves the above problems.
The content of the invention

Specific embodiment
With reference to figure 1 and Fig. 2, an implementation of baby's vehicle control for directional rotating can be realized by disclosing the present invention
Example, includes：Wheel seat 2, wheel group 3, fixed seat 4, locating rod 5, elastic parts 6, preceding foot lever 10, through hole 11, sleeve 20, appearance
21, through hole 22 between emptying, outer cover 23, wheel 30, wheel shaft 31, front fork tube 32, through hole 41, screw inclined plane 42, blocking part 51,
Pull handle 52, the conical surface 311 rotate groove 312, positioning region 313, end face 521.
With reference to figure 1, the baby's vehicle control that can realize directional rotating shown in the present embodiment, main device is in baby
10 lower end of preceding foot lever of vehicle skeleton, uses orientation, non-directional and the dismounting of control wheel group 3；The present embodiment includes：One wheel seat 2,
One wheel group 3, a fixed seat 4,5 and one elastic parts 6 of a positioning rod.
Wherein wheel seat 2 is connected to preceding 10 lower end of foot lever, and among the present embodiment, which is welded in preceding foot lever for one
10 lower end inside faces, and perpendicular to the sleeve 20 on ground, middle sleeve 20 has an accommodating space 21, for the wheel shaft of wheel group 3
31 rotate in the accommodating space 21, and in the sleeve 20 compared with being provided with pass through aperture 22 at the preceding foot lever 10, and in the set
20 top of cylinder set one can the top of sealing sleeve 20 outer cover 23, wheel shaft 31 is limited by outer cover 23, so that wheel shaft 31 can be stablized
It rotates.
Wheel group 3 be pivotally connected wheel 30, among the present embodiment, 30 system of wheel by one in inverted u-shaped front fork tube 32 be pivotally connected
Wheel 30, system vertically extends wheel shaft 31 above the front fork tube 32, and wherein 31 front end of wheel shaft is a conical surface 311, so that wheel shaft
31 are easily accessible in the accommodating space 21 of wheel seat 2, and are moved by 311 ejection locating rod 7 of the conical surface；And in the appropriate location of wheel shaft 31
System is equipped with a rotation groove 312 for surrounding wheel shaft 31, and a positioning region 313 is equipped in groove 312 in rotating, and works as in the present embodiment
In the positioning region 313 be a groove.
Fixed seat 4 is fixedly connected on preceding 10 lower end outside face of foot lever, has one to run through with preceding 10 lower end of foot lever and sleeve 20
The concentric through hole 41 in hole 11,22, and the outboard end in fixed seat 4 is equipped with a screw inclined plane 42.
Locating rod 5 is movably installed on the fixed seat 4 and in the through hole of preceding foot lever 10 11,41, one end of locating rod 5
Portion is free end, and forms a blocking part 51, and obtains blocking part 51 and enter via through hole 11,41,22 in sleeve 20, and with
313 clip of positioning region of wheel shaft 31.Then a chain for binding criminals consolidates a pull handle 52 to the other end of locating rod 5, makes end face 521 and the fixed seat of pull handle 52
4 screw inclined plane 42 contacts.
Elastic parts 6 is installed between locating rod 5 and preceding foot lever 10, uses the clip kept to wheel group 3.In the present embodiment
In the middle, elastic parts 6 is a compression spring.
With reference to shown in figure 3-5, by above-mentioned component, locating rod 5 is to make locating rod 5 by elastic parts 6 under normality
Blocking part 51 be located in the positioning region 313 of wheel shaft 31（First position:As shown in Figure 3）, it can not be rotated with limiting wheel shaft 31, and
It is in directional rotating to make wheel group 3.When operator rotates pull handle 52, since 521 system of end face of pull handle 52 and the spiral of fixed seat 4 are oblique
Face 42 contacts, when making the rotation of pull handle 52, along the ejection of screw inclined plane 42, so that locating rod 5 moves and recesses positioning region 313,
It is located at its blocking part 51 to rotate in groove 312（The second position:As shown in Figure 4）, so that wheel shaft 31 is limited by locating rod 5,
And make wheel shaft 31 can be in being rotated in the sleeve 20, so that wheel group 3 must be 360 degree freely turns to.
When operator pulls locating rod 5 by pull handle 52 again, then depart from the blocking part 51 of locating rod 5 and rotate groove 312
（The third place:As shown in Figure 5）.At this point, limitation of the wheel shaft 31 from locating rod 5, and then sleeve 20 must be departed from.
Among the present embodiment, when locating rod 5 is located at first position, be direct pull locating rod 5 to the third place,
And directly to dismantle wheel group 3, to reach convenient effect.
The baby's vehicle control provided by the invention that can realize directional rotating is movably determined in setting one in wheel group
Position bar, wherein locating rod tool is there are three shift position, and first position system makes the wheel group, and in directional rotating state, second position system makes
The wheel group in being freely rotated state in wheel seat, the third place then makes the wheel group depart from derived from wheel seat, uses that provide user light
The rotation of easy selection wheel group or orientation and easy assembly and disassembly wheel group, thus the rotation of perambulator can be made more steady
Smoothness, will not be because of external force or obstacle the reason for, are out of control, generate and improperly rotate or position, it is ensured that the use of perambulator
Safety, more convenient operation.
It is above disclosed to be merely a preferred embodiment of the present invention, the right of the present invention cannot be limited with this certainly
Scope, therefore the equivalent variations made according to scope of the present invention patent, are still within the scope of the present invention.
