Abstract

The utility model relates to a multipurpose children's cycle, which is the improvement of the existing children's cycles with two wheels. The structure feature of the utility model is that a rear rack and a fork plate are improved, a rear long shaft is additionally arranged on the cycle, one rear wheel can be arranged on the rear rack, and two rear wheels can also be arranged on the rear rack to conveniently realize the conversion of the children's cycle with third wheels and the children's cycle with two wheels to prolong the service time.

Description

How by bike with children

The utility model belongs to the perambulator technical field.

Existing children ride and use car, no matter are three-wheel vehicle or two-wheeled cycle, mostly only have simple function, applicable time weak point in the child growth process, and practical value is low, causes waste.The patent No. is 91216732.7 multifunctional assembled perambulator, though can realize by bike and the conversion of go-cart that its complex structure can not be realized the conversion of three-wheel vehicle and two-wheel car equally.

The purpose of this utility model provides that a kind of many it can be converted to two-wheeled cycle with toy tricycle easily, thereby can increase the service life with children by bike, improves the practical value of perambulator.

The utility model is the improvement to existing children's two-wheel car, it has big roof beam structure equally, is installed in the handlebar and the fork blade of big roof beam structure front end, and a front-wheel and brake are installed on the fork blade, big roof beam structure lower end is equipped with hinge wheel and foot-operated, and saddle is equipped with in the upper end of big roof beam structure.Its constructional feature is the after-frame that a bending is installed in the back of big roof beam structure, and the rear end lower of after-frame is fixed with the fork plate, and back major axis is installed in the notch of fork plate by connecting panel.Two ends at the back major axis respectively are equipped with a trailing wheel, and the middle part of back major axis is installed with the sprocket wheel cover, and sprocket wheel puts to be equipped with by hinge wheel and passes through the chain-drive minor sprocket, constitutes a toy tricycle.

The utility model also is equipped with standby sprocket wheel cover on therein the trailing wheel, is used to install minor sprocket.And minor axis and two protection wheel after having, be used for three-wheel vehicle is changed over two-wheel car.

The utility model has the advantages that: it can be transformed to two-wheeled by bike with children's three-wheel easily by bike, correspondingly along with children's growth has prolonged its applicable time, has improved practical value, thereby reduced family expense, avoid waste, and conversion is flexible, very easily adjusts.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is an integral structure scheme drawing of the present utility model;

Fig. 2 is transformed to the integral structure scheme drawing of cart for the utility model.

In the embodiment that accompanying drawing provides, the first half of first half of the present utility model and existing two-wheeled perambulator is identical, it has the big roof beam structure 4 of a bending, the front end of big roof beam structure 4 is equipped with handlebar 5 and fork blade 19, a front-wheel 1 is equipped with by front axle 20 in fork blade 19 lower ends, and brake 3 and front fender 2 also are housed on fork blade.Saddle 9 is equipped with in the upper end of big roof beam structure 4, and hinge wheel 8, pedal 6 and chain cover plate 7 are equipped with in the lower end.The after-frame 10 of a bending is installed in the back of big roof beam structure 4, and the rear end lower of after-frame 10 is fixed with two blocks of fork plates 13, be equipped with one in the notch of fork plate 13 after major axis 16, back major axis 16 is to be fixed in by connecting panel 14 and screw to pitch on the plate.Two ends at back major axis 16 respectively are equipped with a trailing wheel 11 by nut and clamp 15, are fixed with a sprocket wheel cover at major axis 16 middle parts, back, and the minor sprocket 17 that is driven by chain 8 by hinge wheel 18 is installed on it.On a trailing wheel 11 the standby sprocket wheel cover that can adorn minor sprocket is installed therein, taillight 12 also is housed on the after-frame 10.21, two protection wheels 23 of minor axis and protection stalk 22 and back mud plate 24 after the utility model also has one are in order to be transformed into two-wheel car with it.

The method of adjustment that the utility model three-wheel vehicle is converted to two-wheel car is as follows:

Back out the nut on the trailing wheel (11) that has the sprocket wheel cover, take off this trailing wheel from back major axis 16; Unscrew the screw on the connecting panel 14, unclamp chain 8, from fork plate 13 notches, withdraw from back major axis 16; Turn on the tightening screw that sprocket wheel puts, the sprocket wheel cover is extracted out from axle, and minor sprocket 17 put from sprocket wheel screw off, install to then on the trailing wheel that has standby sprocket wheel cover; With standby back minor axis 21 trailing wheel 11 of packing into, adjust spool a two ends distance and a fastening nut, with minor sprocket 17 process chains 8, the trailing wheel back vent plate 13 of packing into, regulate the chain tightness, back minor axis 21 two ends reinstall protection stalk 22, and are pressed on the fork plate with nut, load onto protection wheel 23 in protection stalk 22 lower ends; Utilize the screw that taillight 12 is installed that standby back mud plate 24 is fixed on the after-frame 10, promptly form a two-wheel children bicycle.
