The utility model discloses simple structure, simple to operate, the effect is showing, and it can effectively be solved behind the current children bike and to produce not hard uply and the inhomogeneous technical problem of auxiliary wheel wearing and tearing between auxiliary wheel support frame and the auxiliary wheel screw.
Description
Technical field
The utility model belongs to child's bicycle manufacturing technology field, is specifically related to a kind of child's bicycle auxiliary wheel bracing or strutting arrangement.
Background technology
Child's bicycle is one of present of preferring of the children in 4-6 year, is also that children for learning rides the best instrument of two-wheeled cycle.Most child's bicycle arranges auxiliary wheel in trailing wheel both sides, stablizes to keep vehicle body.Auxiliary wheel is fixed on trailing wheel erecting frame by bracing frame, existing auxiliary wheel bracing or strutting arrangement, and pipe or the band steel of adopting bends l-shaped more, and auxiliary wheel is fixed by screws in the lower end of L-type.Because screw is that one end and L-type bracing frame are fixed, so screw is easily from loose or dislocation L-type bracing frame; Can cause again auxiliary wheel discontinuity on screw, Long-Time Service can cause the wearing and tearing between auxiliary wheel and screw not of uniform size, and the endoporus of auxiliary wheel large position of wearing and tearing easily extrudes cracking, thus shortens the service life of auxiliary wheel; Except, L-type bracing frame easily produces by External Force Acting distortion of bending again.
Summary of the invention
It is relatively simple, easy to operate that the purpose of this utility model is to provide a kind of structure, reasonable in design and improve the child's bicycle auxiliary wheel bracing or strutting arrangement of Be very effective, it can solve existing children voluntarily after auxiliary wheel supporting way with various drawbacks.
For achieving the above object, a kind of child's bicycle auxiliary wheel of the utility model bracing or strutting arrangement, it comprises bracing frame, auxiliary wheel, screw axis, captive nut and anti-avulsion mat, L-type is made in described bracing frame one end, straight flange is provided with fixed orifice, the other end is made U-shaped, two U-shaped straight flanges are equipped with screw axis, the centre of described screw axis is provided with auxiliary wheel, one end of screw axis is provided with threaded end, described threaded end is connected with captive nut, threaded end outside described captive nut is provided with anti-avulsion draw-in groove on the surface, anti-avulsion mat is provided with in described anti-avulsion draw-in groove, the both sides of described auxiliary wheel are respectively equipped with left distance sleeve and right distance sleeve.
In technique scheme, the centre of described screw axis is provided with optical axis, and the diameter of optical axis 1.5 ~ 4mm larger than the large footpath of threaded one end head.
Stirrup is provided with between the U-shaped straight flange of described bracing frame and L-type straight flange.
After adopting technique scheme, the two ends of screw axis are fixed on two straight flanges of the U-shaped structure of bracing frame, this fixed form is fixed on L-type bracing frame than one end, solid and reliable, can avoid again occurring that screw axis frequently crosses the phenomenon of quick-wearing from the loosening disengagement of bracing frame and auxiliary wheel local.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of child's bicycle auxiliary wheel of the utility model bracing or strutting arrangement.
Respectively be designated in accompanying drawing: 1, bracing frame, 11, fixed orifice, 2, auxiliary wheel, 3, screw axis, 31, threaded end, 32, anti-avulsion draw-in groove, 33, optical axis, 4, left distance sleeve, 5, right distance sleeve, 6, captive nut, 7, anti-avulsion mat, 8, stirrup.
Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of child's bicycle auxiliary wheel of the utility model bracing or strutting arrangement is described further:
As seen from Figure 1, the utility model it comprise bracing frame 1, auxiliary wheel 2, screw axis 3, captive nut 6 and anti-avulsion mat 7, L-type is made in described bracing frame 1 one end, straight flange is provided with fixed orifice 11, the other end is made U-shaped, two U-shaped straight flanges are equipped with screw axis 3, the centre of described screw axis 3 is provided with auxiliary wheel 2, one end of screw axis 3 is provided with threaded end 31, described threaded end 31 is connected with captive nut 6, threaded end 31 outside described captive nut 6 is provided with anti-avulsion draw-in groove 32 on the surface, is provided with anti-avulsion mat 7 in described anti-avulsion draw-in groove 32; The both sides of described auxiliary wheel 2 are respectively equipped with left distance sleeve 3 and right distance sleeve 4.
Installation method of the present utility model is, first auxiliary wheel 2 is installed, screw axis 3 is penetrated again successively through after left distance sleeve 4, auxiliary wheel 2 and right distance sleeve 5 from the outside that the U of bracing frame 1 holds, the threaded end 31 of screw axis 3 is stretched out bracing frame 1, captive nut 6 is tightened on threaded end 31, and anti-avulsion mat 7 is sticked in dislocation preventing slot 32; Finally be fixed on trailing wheel erecting frame by bracing frame 1, and adjust the terrain clearance of bracing frame 1, it is highly about 10mm ~ 30mm.
In the present embodiment, the centre of described screw axis 3 is provided with optical axis 33, and the diameter of optical axis 33 1.5 ~ 4mm larger than the large footpath of threaded one end head 31, this both ensure that the support strength of screw axis 3, can ensure that again auxiliary wheel 2 rotates flexibly; The surface of described threaded end 31 is provided with anti-avulsion draw-in groove 32, is provided with anti-avulsion mat 7 in described anti-avulsion draw-in groove 32, and this structure can guarantee that captive nut 6 can not from accidental bracing frame 1.
In the present embodiment, stirrup 8 is provided with between the U-shaped straight flange of described bracing frame 1 and L-type straight flange, this technical scheme not only can improve the intensity of bracing frame 1, and the extruding that bracing frame 1 can be avoided again to be subject to external force produces distortion, reaches the object extending its service life.
