Abstract
The utility model provides a rotary and anti-vibrating mechanism for baby perambulator wheel set, comprising wheel fork arms (3) which is fixed on the wheels (1) of the perambulator through wheel axles (2), wheel fork joints (4) which are rotationally combined with the wheel fork arms (3) through fastening bolts (8), and a torsion spring (7) whose one end is clamped in the concave groove (12) of the wheel fork arm (3) and whose the other end is clamped in the concave groove (13) of the joint (4) of the wheel fork. When the wheels (1) vibrate up and down, the wheels (1) drive the wheel fork arms (3) rotate by regarding the fastening bolts (8) as axles, the torsion spring (7) is driven to twist, and accordingly, the torsion spring (7) absorbs the vibration of the wheels (1). The utility model has the advantages that the utility model has simple structure and anti-vibrating, and the running of the perambulator is more smooth.
Description
Technical field
The utility model relates to baby stroller, particularly rotation of the set of wheels of baby stroller and shockproof mechanism.
Background technology
Existing baby stroller all is that wheel is directly installed on the vehicle frame of hand barrow by modes such as welding, be spirally connected usually, and its structure is very simple.Yet, hand barrow and rough road traveling in, concavo-convex road surface tends to make hand barrow to produce very big vibrations, the utmost point that travels is not steady, makes that the baby does not feel well in the car.In addition, when hand barrow need be turned or be got around obstacle, it controlled also comparatively difficulty.
The utility model content
The technical problems to be solved in the utility model is, a kind of simple in structure, shock-absorbing when hand barrow is travelled, handy, rotation of pulsation-free baby stroller wheels and shockproof mechanism more are provided.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of baby stroller wheels rotation and shockproof mechanism, comprise by wheel shaft and be fixed on wheel yoke on the wheel of hand barrow, take turns the rotatable wheel fork connector that combines of yoke by binding bolt with described, and an end is fastened on the described interior torsion spring of the groove that groove is interior, the other end is fastened on described wheel fork connector of taking turns yoke.
The described yoke of taking turns of above-mentioned baby stroller wheels rotation and shockproof mechanism inwardly is provided with the sheathed and hollow projection that supply described binding bolt to pass for described torsion spring.
Above-mentioned baby stroller wheels rotation and the described wheel fork connector of shockproof mechanism top are connected with the S. A. permanent seat by S. A., and described S. A. permanent seat is connected with the baby stroller vehicle frame.
In above-mentioned baby stroller wheels rotation and the described S. A. permanent seat of shockproof mechanism the bearing that is set on the S. A. is arranged.
Rotation of above-mentioned baby stroller wheels and the described S. A. of shockproof mechanism be arranged on described binding bolt directly over or depart from directly over a side.
The top of above-mentioned baby stroller wheels rotation and the described S. A. permanent seat of shockproof mechanism also is provided with S. A. permanent seat loam cake.
The above-mentioned baby stroller wheels rotation and the described S. A. permanent seat of the shockproof mechanism outside are hinged with the spline lock; The phase-locked cooresponding position of described wheel fork connector and described spline is provided with the groove that supplies described spline pintle hook lock to go into.
Compared with prior art, the utility model baby stroller wheels rotations and shockproof mechanism are that axle rotates with the binding bolt by wheel driven wheel yoke when up and down vibrations of wheel, drive torsion spring and reverse, thereby absorbed the vibrations of wheel by torsion spring; Can also drive wheel by S. A. in addition and do axial rotation, have simple in structure, rotatable, shock-absorbing, the hand barrow pulsation-free advantage more of travelling.
Description of drawings
Below in conjunction with drawings and Examples rotation of the utility model baby stroller wheels and shockproof mechanism are described further, in the accompanying drawing:
Fig. 1 is the decomposing schematic representation of rotation of the utility model baby stroller wheels and shockproof mechanism.
Fig. 2 is the enlarged diagram of wheel yoke, torsion spring and the wheel fork connector of rotation of the utility model baby stroller wheels and shockproof mechanism.
Fig. 3 is the scheme drawing of the combination (spline lock release position) of rotation of the utility model baby stroller wheels and shockproof mechanism.
Fig. 4 is the scheme drawing that amplify the part of the spline lock locking state of rotation of this baby stroller of the utility model wheels and shockproof mechanism.
Fig. 5 is the scheme drawing that the S. A. of rotation of the utility model baby stroller wheels and shockproof mechanism is arranged on a side of binding bolt.
The specific embodiment
Below in conjunction with accompanying drawing baby stroller wheels rotation of the present utility model and shockproof mechanism are described in further detail.Please Fig. 1 to Fig. 5, the utility model baby stroller wheels rotations and shockproof mechanism comprise by wheel shaft 2 and are fixed on wheel yoke 3 on the wheel 1 of hand barrow, take turns the yoke 3 rotatable wheel fork connectors 4 that combine by binding bolt 8 with described, and the torsion spring 7 in the groove 13 that an end is fastened in the described groove of taking turns yoke 3 12, the other end is fastened on described wheel fork connector 4.When the wheel 1 of hand barrow is stressed, wheel 1 drives the described yoke 3 of taking turns and takes up fixing bolt 8 and rotate for axle, thereby driving described torsion spring 7 reverses, under the effect of the elastic restoring force of torsion spring 7, absorbed vibrations, thereby made hand barrow more steady when travelling from wheel 1 or other parts.
The described yoke 3 of taking turns inwardly is provided with for described torsion spring 7 sheathed and hollow projections 14 that supply described binding bolt 8 to pass, increased the rigidity of torsion spring 7, and make binding bolt 8 easierly to pass through, the described yoke 3 of taking turns is connected with described wheel fork connector 4.Described wheel fork connector 4 tops are connected with S. A. permanent seat 5 by S. A. 9, and described S. A. permanent seat 5 can be connected with baby stroller vehicle frame (figure does not indicate) by modes such as welding, be spirally connected.The bearing 10 that is set on the S. A. 9 is arranged in described S. A. permanent seat 5, rotate within it for S. A. 9.Described S. A. 9 can be arranged on described binding bolt 8 directly over or depart from directly over a side (as Fig. 3 and shown in Figure 5).The top of described S. A. permanent seat 5 also is provided with S. A. permanent seat loam cake 11, protects described S. A. permanent seat 5 interior parts not to be subjected to the pollution of dust.
Be hinged with spline lock 6 in described S. A. permanent seat 5 outsides; And described wheel fork connector 4 is locked 6 corresponding positions with described spline and is provided with for described spline lock 6 grooves that snap in 15.When pulling described spline lock 6 and snap in described groove 15 in, make S. A. permanent seat 5 and described wheel fork connector 4 lock, can't make axial rotation, thereby make hand barrow orientation to travel.
