Description

A kind of improved scooter Folding 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 Folding structure of scooter.

The structure of scooter roughly can be divided into three parts, and the first has the telescopic front frame of handgrip, the base of the foot-operated usefulness of its two person of being to use, and it three is rollers of the whole slip usefulness of scooter.

Why scooter is liked by people, traces it to its cause, and is that it has the convenience of slide plate and controls stable effect, and need not superb technology and skill need be arranged, and only need get final product by bike as the control slide plate.Though existing scooter is provided with folding mechanism, they all exist operation inconvenience to reach defectives such as not portable.Therefore, need update, make it reach safe in utilization, be easy to carry, fold targets such as convenient to operation the structure of scooter.

The purpose of this utility model is to provide a kind of improved scooter Folding structure, so that make the better effects if that folds of scooter, material therefor more reduces, and carries conveniently, operates more simply, and structure is more reliable

For achieving the above object, the utility model provides a kind of improved scooter Folding structure, this structure comprises front frame 10 and base 50, both are connected as a single entity by folding device 30, and the front frame bottom is connected with bolt with base rear end, it is characterized in that described folding device 30 is made of outrigger 31, internal frame 32 and cross connecting rod 47, wherein the outrigger two ends flexibly connect with internal frame and base respectively; The internal frame other end and front frame flexibly connect; Cross connecting rod is contained in the internal frame, and its overhanging end is connected with nut 81.

Described outrigger 31 is that cross section is the groove shape body of U-shaped, and the one end is provided with open-work 311, groove 312 and U-lag 313, and outrigger is connected with bolt with internal frame.

Described internal frame 32 is the shaft-like body of a rectangle, and the one end is connected with front frame with bolt, and the other end then is provided with the open-work 41 that is connected usefulness with outrigger, the slide opening 42 that supplies cross connecting rod slip usefulness, latch holder 45 and the groove 46 that the fixed cross connecting rod is used.

Described cross connecting rod 47 is the shaft-like body of cross, and the one end is fixed on the latch holder 45 on the internal frame by

latch

44, and 48 of its two side levers place in the slide opening 42 on the internal frame, and its other end is provided with the threaded portion 49 that is connected with nut 81.

The outward flange of described outrigger 31 end face U-lags 313 is provided with the depression 314 for nut 81 location usefulness.

As seen from the above technical solution, scooter Folding structure of the present utility model is a kind of link rod structure, this structure not only makes inside and outside of device for folding, and each parts of scooter are linked together dexterously, and thereby scooter can be opened and be located very easily when launch using, when not using, can fold quickly and easily again and fold, and because when collapse state, internal frame can collapse in the outrigger, makes Folding structure compact more, and has saved material.The security reliability that the utility model thereby reached uses, fold the convenience of operation and the convenience of carrying.

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

The utility model is a kind of improved scooter Folding structure, and it includes front frame 10, base 50 and folding device 30, and front frame 10 links into an integrated entity by folding device 30 with base 50.

Folding device 30 structures are shown in Fig. 4～6, and it is made of outrigger 31, internal frame 32 and cross connecting rod 33.Internal frame 32 is the shaft-like body of a rectangle, the one end is provided with open-work 71, this open-work is corresponding with the open-work 10 on the front frame, internal frame and front frame flexibly connect with bolt through two open-works, and the internal frame other end is provided with the open-work 41 that is connected usefulness with outrigger, the slide opening 42 that supplies cross connecting rod slip usefulness, latch holder 45 and the groove 46 that the fixed cross connecting rod is used.

As shown in Figure 5, outrigger 31 is that cross section is the groove shape body of U-shaped, and the one end is provided with open-work 311, groove 312 and U-lag 313, and outrigger and internal frame run through outrigger open-work 311 with bolt group 61 and internal frame open-work 41 flexibly connects.The outrigger other end then is movably connected on the holder 51 on base 50 tops with bolt.

Consult Fig. 4, cross connecting rod 47 is the shaft-like body of cross, it is contained in the internal frame 32, the one end is fixed on the latch holder 45 on the internal frame by

latch

44,48 of its two side levers place in the slide opening 42 on the internal frame, make the stroke of two side levers only limit to slide in slide opening, when folding mechanism was in deployed condition, two side levers 48 were against on the groove 312.The other end of cross connecting rod is provided with threaded portion 49, and this threaded portion is connected with embossing nut 81.

Front frame 10 runs through the open-work 12 of front frame bottom with base 50 usefulness bolt groups and the open-work 53 of base front end flexibly connects (see figure 2).

Consult Fig. 7, Fig. 8, when amounting to folding device 30, only need unclamp embossing nut 81, just can fold for the axle center bends by bolt 61.When bending folded, two side levers 48 of cross connecting rod broke away from from the groove 312 on the outrigger in advance.When needs fold scooter, only need front frame 10 is rolled over toward base 50 1, just can bolt group 61 amount to for the axle center.Fig. 3 shows the collapse state of scooter.

As seen by above-mentioned, because outrigger 31 is the U-lag structure, when amounting to, internal frame 32 can collapse in the outrigger, thereby makes folding device shorter and smaller light and handy.In addition, owing to be provided with cross connecting rod 47, upon deployment, available embossing nut 81 is fastening and can not produce the phenomenon that gets loose with outrigger and internal frame.

And then as shown in Figure 8, the U-lag 313 bottom outer rims on the outrigger 31 can be provided with a depression 314, and voltage supply flower nut 81 is located usefulness when fastening.
