Description

Child's scooter

Technical field

The present invention relates to toy for children technical field, more particularly, to a kind of child's scooter.

Background technology

Scooter is toy for children more popular at present.Generally, scooter includes vehicle frame, and the front portion of the vehicle frame is articulated with In vertical vertical rod, the upper end of the vertical rod is provided with front-wheel provided with handrail, lower end, and the rear portion of the vehicle frame is articulated with what is extended horizontally Rotary shaft, the both ends of the rotary shaft are fixed with trailing wheel.Meanwhile scooter is additionally provided with the drive mechanism by pedal-driven.Mostly The defects of number scooter, is：It is more laborious when forward, it is extremely inconvenient, it is necessary to be moved away from ground during retrogressing.

The content of the invention

For above-mentioned the shortcomings of the prior art, it is an object of the invention to provide a kind of child's scooter, before it has Enter and retreat the characteristics of more flexible.

To achieve these goals, the technical solution adopted in the present invention is：Child's scooter, including vehicle frame, the vehicle frame Front portion be articulated with vertical vertical rod, the upper end of the vertical rod is provided with handrail, lower end is provided with front-wheel, and the rear portion of the vehicle frame is articulated with The rotary shaft to extend horizontally, the both ends of the rotary shaft are fixed with trailing wheel, and it is in horizontal front axle that the front portion of the vehicle frame, which is provided with, is had The front end of 2 pedals is articulated in the both ends of the front axle respectively, and is fixed with the connecting rod extended downwardly on the downside of the rear portion of pedal, together When, the rear portion of the vehicle frame is articulated with is respectively fixed with a crank, the extension of 2 cranks in horizontal rear axle, the both ends of the rear axle Direction is in 180 °, and the other end of crank is hinged at the lower end of corresponding connecting rod, and, coaxially it is fixed with driving tooth on the rear axle Take turns, driven gear is coaxially fixed with the rotary shaft, the driving gear and the driven gear engage.

The number of teeth of the driving gear is more than the number of teeth of the driven gear.

After said structure, the invention has the advantages that compared with the prior art,：Move forward and backward more clever It is living.The child's scooter of the present invention is when in use, it is only necessary to steps on 2 pedals in turn, you can driving scooter travels forward.Instead It, when needing to retreat, trailing wheel will not be hindered by pedal, remain able to conveniently retreat, it is not necessary to necessarily pick up cunning Wooden handcart.

Brief description of the drawings

The present invention is further described with reference to the accompanying drawings and examples：

Fig. 1 is the front view (broken section) of the child's scooter of embodiments of the invention；

Fig. 2 is the stereogram of the section components of the child's scooter of embodiments of the invention.

Embodiment

Embodiment, as shown in Fig. 1 and Fig. 2：Child's scooter, including vehicle frame 10.The vehicle frame 10 is preferably a front and back It is prepared by the tubing upwardly extended.The front portion of the vehicle frame 10 is articulated with is provided with handrail in vertical vertical rod 20, the upper end of the vertical rod 20 21st, lower end is provided with front-wheel 22.The rear portion of the vehicle frame 10 is articulated with the rotary shaft 30 to extend horizontally, and the both ends of the rotary shaft 30 are consolidated Surely there is trailing wheel 31.That is, the rotary shaft 30 is moved towards in left and right, and trailing wheel 31 is separately fixed at left part and the right-hand member of the rotary shaft 30 Portion.

Further say：

It is in horizontal front axle 11 that the front portion of the vehicle frame 10, which is provided with,.Accurately say, the middle part of the front axle 11 is fixed on the vehicle frame On 10, so the left end and right-hand member of the front axle 11 are located at the left and right sides of the vehicle frame 10 respectively.In other words, the front axle 11 is two Section, one section is respectively fixed with the left and right sides of the vehicle frame 10.The front end for having 2 pedals 40 is articulated in the two of the front axle 11 respectively End.That is, the bottom of pedal 40 is provided with sleeve pipe, and what shell clearance coordinated is enclosed on corresponding front axle 11.Under the rear portion of pedal 40 Side is fixed with the connecting rod 50 extended downwardly.Meanwhile the rear portion of the vehicle frame 10 is articulated with horizontal rear axle 12, the two of the rear axle 12 The bearing of trend that end is respectively fixed with 60,2 cranks 60 of crank is in 180 °, and the other end of crank 60 is hinged at corresponding connecting rod 50 lower end.For example the rear axle 12 or so trend, crank 60 are respectively and vertically fixed at the left end and right-hand member of the rear axle 12.And Driving gear 71 is coaxially fixed with the rear axle 12, driven gear 72 is coaxially fixed with the rotary shaft 30, the driving gear 71 Engaged with the driven gear 72.Preferable mode is that the number of teeth of the driving gear 71 is more than the number of teeth of the driven gear 72.This Sample, it is only necessary to step on 2 pedals 40 in turn, you can drive the driving gear 71 to rotate, drive the driven gear 72 to rotate, then should Rear axle 12 rotates, and 2 trailing wheels 31 rotate, and the scooter moves ahead；Conversely, without scooter is moved away from into ground, also can conveniently and Easily it is moved rearwards the scooter.

The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the scope of the invention, every utilization The equivalent structure or equivalent flow conversion that description of the invention and accompanying drawing content are made, or directly or indirectly it is used in other correlations Technical field, be included within the scope of the present invention.
