Description

Riding cycle children's seat

Technical field

It the utility model is related to a kind of riding cycle children's seat.

Background technology

At present, under the call of country, the environmental consciousness of the common people is more and more stronger, and all kinds of low-carbon trip modes are in the ascendant. And bicycle, motor bicycle are even more the main means of transport of low-carbon trip.The shared bicycle especially to come into vogue in recent years, even more will Low-carbon riding cycle trip mode has been generalized to a new height.

Shared bicycle refers to that enterprise carries in campus, subway station, bus station, residential block, shopping centre, common service area etc. It is a kind of timesharing leasehold mode for bicycle bicycle shared service.Shared bicycle is a kind of new shared economy.

Shared bicycle is just rented with business-bicycle rent with business its essence is a kind of new vehicles, its mainly according to It is (bicycle) bicycle by carrier.The cycling trip that can make full use of very much city to be brought by quick economic development is dispirited Situation；Maximumlly it make use of public way percent of pass.Play the role of healthy body at the same time, and can be with by means of with stopping, very It is convenient.

Since the end of the year 2016, the shared bicycle in the country is just hot suddenly to get up, and in street corner, seemingly overnight, shares single Car has arrived the stage of " spreading unchecked ", and each big city roadside is booked the shared bicycle of a variety of colors.

Although shared bicycle has certain convenience, but just less convenient for the people for the trip that carries small children, and does not have Children's seat is designed, and child can be placed in the bicycle basket of shared bicycle by many people in order to easy and convenient, so be very Dangerous.Simultaneously because shared bicycle is not the vehicle of bicyclist oneself, children's seat needs fast-assembling, using terminating when in use After need Quick Release to take back, existing child seat product cannot generally realize tool-free fast mounting-dismounting well.

In addition to shared bicycle, the present invention is also applicable to the camber beam bicycle and motor bicycle of adjustable sitting height.Because can in order to avoid Tool fast-mounting Quick Release so that user easily can only install children's seat when needed.Particularly with overcritical light-weighted Aluminium alloy, titanium alloy, carbon material specialty bicycle, meaning are obvious.

The content of the invention

The purpose of this utility model is to provide a kind of riding cycle children's seat easy to carry, versatility is good.

The purpose of this utility model can be realized by following technical proposal：

Riding cycle children's seat, it is characterised in that：Including crossbeam, front fork, the cushion being arranged on crossbeam, crossbeam is with before Connection angle between fork is adjustable, and is fixedly connected after angle-determining by a position-limit mechanism；The company of crossbeam and front fork The place of connecing is provided with folding handrail, and handrail is fixed after being determined with crossbeam relative position by position-limit mechanism；It is provided with front fork The adjustable spandrel girder in position, spandrel girder are erected on the oblique car pipe of riding cycle；Front fork biside plate bottom is equipped with turnover foot Step on；The rear end of crossbeam is provided with the axle attachment sat pipe with riding cycle and be connected.The utility model is a folding structure, no In use, the space of very little can be folded into, it is convenient for carrying.

Further, the axle attachment includes the connecting portion being connected with crossbeam and is fastened on the pipe clamp sat on pipe, pipe clamp Openend by knob locking member fasten fix, knob locking member include first knob, be hinged on the first knob first pin Axis, the outer end of the first axis pin are equipped with the first locking nut of adjustable openings end spacing, and first locking nut includes nut With spherical spiral shell body, spherical spiral shell body coordinates the first axis pin of positioning with the spherical through hole on pipe clamp.The utility model shake hands locking member with Riding cycle connection is fixed, efficient and convenient without using instrument, dismounting.Positioning the first axis pin by spherical structure at the same time can fit Various sizes of sit is answered to manage.

Further, the pipe clamp includes the hinged first clamping plate and second clamping plate in one end, and the free end of second clamping plate is provided with First axis pin moves along the notch of adjustment installation site, is provided with and second clamping plate free end on the hinged end of the first axis pin Outer surface coordinates the locating plate for determining the first axis pin position.When the opening of first clamping plate and second clamping plate is a flared structure When, the gradient of the first axis pin is positioned by locating plate, then the first axis pin is adapted to by the spherical structure of the first locking nut Gradient.

Further, be equipped with the first clamping plate and second clamping plate and sit the arc sections that are bonded of pipe, the arc sections by The circular arc of multistage different-diameter is in smoothing junction to be formed, so that pipe clamp can be bonded with various sizes of seat pipe, use scope Extensively.

Further, the position-limit mechanism includes the second knob, the second axis pin for being hinged on the second knob, on the second axis pin Be equipped with the biside plate of front fork, multiple metal connecting pieces, metal connecting piece be arranged between biside plate and respectively with crossbeam, handrail It is fixedly connected, the outer end of the second axis pin is equipped with the second locking nut for preventing element falling thereon；The both sides of metal connecting piece, with And the inner side top of biside plate is equipped with gear structure, between metal connecting piece and metal connecting piece, metal connecting piece and side plate Positioning is engaged by gear and is fixed by fastening of shaking hands.Position-limit mechanism securely and reliably, is passed through by gear structure positioning limit Knob opens fastening, and use is efficient and convenient.

Further, internal be equipped with is driven between the metal connecting piece and metal connecting piece, metal connecting piece and side plate The tower spring that gear engagement separates.

Further, the cushion includes two alar parts of cushion and prominent crossbeam, and alar part is can be to cushion surface Fold is connected in cushion.When not in use, alar part is turned down to cushion surface, and will by the handrail after folding Alar part after fold is fixed, and reduces the size after seat folds, handy to carry about.

Further, the handrail is the rectangular configuration of a chamfering, handrail outer surface is enclosed with spongy layer, and one supplies child Handrail, two protect child, prevent from dashing forward in emergency brake and handlebar collides, while have a sponge buffering, reduce shock Impact force.

Further, the foot-operated tread is that rotary setting, the tread are equipped with arc surface to energy relative level forward. With tread it is that face contacts when child is stepped down in footrest, is not the rib contact with tread, so that child can relax Suitable use is ridden.

Further, the biside plate of the front fork is equipped with spandrel girder along sliding the more of the slide that moves and spacing spandrel girder Level tooth mouth, slide are connected with multistage tooth mouth.The model of riding cycle is very much, and size is different, therefore the position of spandrel girder Put adjustable so that seat is adapted to various sizes of riding cycle.

Further, the spandrel girder is formed by multi-section circular arc pipe is in smoothing junction.The spandrel girder and tricycle of arc structure Oblique car pipe can be very good to coordinate, seat will not be caused to horizontally slip, so as to prevent that car pipes and seats cause to grind to more tiltedly Damage.

The beneficial effects of the utility model：Whole seat is small and light after folding, and is convenient for carrying, while dismounts quick side Just, it is safe and reliable.
