Description

The scooter retracting structure

The utility model relates to the scooter that a kind of recreation and amusement and recreation are used, and particularly relates to a kind of scooter that can make and carries out the scooter retracting structure that fast folding folds.

The structure of scooter roughly can be divided into three big members, and the first is for the foot-operated tabular bar shaped slide plate of user, and it two is pillars that are provided with handgrip for the hand-held usefulness of user, and it three is for the whole roller that slides of scooter.

Scooter comes from combining of bicycle and slide plate, thus widely general popular institute like, trace it to its cause, be as good as is that it has the function that folds and launch to use, make it when launching to use, possess the double effects of bicycle and slide plate, do not use when folding, have light and handy portable characteristics again.

Therefore, scooter folds operational convenience and property easy to carry folding, does not take up space and safety in utilization just becomes scooter three big key elements.Yet existing scooter also fails to have concurrently These characteristics.

It is a kind of safe and reliable that the purpose of this utility model is to provide, and folds scooter retracting structure convenient to operation, easy to carry.

For achieving the above object, the utility model provides a kind of scooter retracting structure, this structure contains a strip slide plate 10, skateboard back-end is equipped with rear roller 31, and its front end is articulated with telescopic prop 20, and telescopic prop top and bottom are respectively equipped with handgrip 21 and front wheel 30, it is characterized in that, described slide plate 10 front ends are provided with forked 12 of upwards bending, and the head tube 22 of this forked front end and telescopic prop lower end articulates, and keeper 14 is equipped with in its rear end; Head tube is provided with from top to bottom a fan-shaped support arm 24 by slide plate one side outside, and this fan-shaped support arm flexibly connects by keeper 14 and slide plate.

Have on the described fan-shaped support arm 24 for it and amount to the guide groove 25 that rotates usefulness, its two ends have locating

hole

26,27.

Described keeper 14 comprises a cam handle 140, a pair of spring 141, a pair of sleeve 142 and a backstay 143, wherein backstay passes the guide groove 25 on forked 12 of the nose and the fan-shaped support arm of head tube, be positioned at forked two ends symmetry on the backstay spring 141 and sleeve 142 are housed, 140 of cam handles are contained in an end end of backstay.

As seen from the above technical solution, the utility model not only makes each member of scooter connect more firm by fan-shaped support arm is set in telescopic prop head tube one side, use safer, and after folding, be positioned at the head tube outside because of amounting to the axle center, so whole telescopic prop can be collapsed in two fork arms 15 of nose, effectively reduced the spatial volume after folding, thereby be convenient to more pack and carry.When folding operation, only can launch or fold operation, thereby operate simple and fast more by the pulling cam handle.From the above mentioned, the utlity model has reasonable in design, compact conformation, safe and reliable, easy and simple to handle, characteristics such as be easy to carry about with one.

The utility model is described in further detail below in conjunction with accompanying drawing and a specific embodiment.

Fig. 6 is that the utility model is in the folded state floor map.

Fig. 7 is another keeper floor map of the present utility model.

As shown in Figure 1 and Figure 2, the utility model comprises

slide plate

10 and 20 liang of big members of telescopic prop, and wherein, slide plate 10 is the tabular body of strip, and its rear end is provided with dashboard 11, and rear roller 31 is equipped with in the dashboard bottom.Telescopic prop 20 is formed by the casing fit, and left and right symmetrical handgrip 21 is extended to both sides in its top, and head tube 22 is equipped with in the bottom, and front wheel 30 is equipped with in the head tube bottom.Telescopic prop is articulated in the front end of slide plate.

Main points of the present utility model are that described slide plate 10 front ends extend upward and are bent into forked 12, and the head tube 22 of this forked front end and telescopic prop lower end articulates, and keeper 14 is equipped with in its rear end; Head tube is provided with from top to bottom a fan-shaped support arm 24 by slide plate one side outside, and this fan-shaped support arm flexibly connects by keeper 14 and slide plate.

The outside, above-mentioned head tube 22 bottoms is provided with the lug 23 of band connecting hole, and has the guide groove 25 of amounting to rotation usefulness for it on the fan-shaped support arm 24 of being located at its outside, and its two ends have locating

hole

26,27.

Telescopic prop is that head tube 22 lower ends are placed between forked 12 two fork arms of nose with being connected of slide plate, and runs through the connecting hole 13 of forked front end and the respective connecting on the head tube lug 23 and both are articulated with screw rod 16.

Rear end bending part at forked 12 is equipped with keeper 14, its structure as shown in Figure 3, Figure 4, this keeper comprises a cam handle 140, a pair of spring 141, a pair of sleeve 142 and a backstay 143, wherein backstay passes the guide groove 25 on forked 12 of the nose and the fan-shaped support arm of head tube, be positioned at forked two ends symmetry on the backstay spring 141 and sleeve 142 are housed, 140 of cam handles are contained in an end end of backstay.Above-mentioned sleeve one end places outside forked, and the other end then leans the both sides of the guide groove 25 on fan-shaped support arm.When needs launch scooter to use, but fastening cam handle 140 is located by the sleeve 142 and the mutual inlay card of the locating

hole

26,27 at guide groove 25 two ends.When unclamping cam handle, sleeve 142 is subjected to the effect of spring 141 and breaks away from locating

hole

26,27 on the fan-shaped support arm, and can fold this moment with scooter is folding.

Folded state such as Fig. 5, shown in Figure 6 of folding of the present utility model, when folding except that telescopic prop 20 condensations, the operator only need spur cam handle 140 breaks away from sleeve 142 and the locating hole on the fan-shaped support arm 24 27 on the keeper, can be that axle center switching is backward amounted to screw rod 16 with whole telescopic prop 20, and make the locating hole 26 chimeric location of the sleeve and the fan-shaped support arm other end by cam handle, form collapse state.

Fig. 7 shows another example of keeper of the present utility model, appropriate location in fan-shaped support arm 24 upper and lower end faces is offered locating hole, and a flexible backstay 144 is fixed in 15 bottom surfaces, space between forked two fork arm of slide plate, with the mutual inlay card of the locating hole on fan-shaped support arm end face location.So that make connection more firm, use more reliable.
