Description

The folding device of scooter

The utility model relates to a kind of scooter, refers to a kind of folding device of scooter especially.

Quite popular now scooter, it is mainly at the vehicle frame front and back ends pulley that is pivoted, establish pedal on the stage casing, front bar is pivoted and has handle and the vertical tube of the preceding head sheave of interlock, during use, but its holds handle control front-wheel steer, ride on pedal with one, another pin is trampled the ground support and is pushed away, and when scooter has the inertia force that slides forward, both feet can be received to step on and let alone to slide on pedal, when scooter speed slows down maybe will stop the time, can repeat above-mentioned action and repeatable operation again, make scooter have the laborsaving effectiveness of dividing a word with a hyphen at the end of a line, and have the effect of motion and amusement and recreation concurrently.

The vertical tube steering structure utmost point that has handle and interlock pulley because of scooter takes up space, the order collection, it is very not convenient to carry, so there is the dealer vertical tube to be made as the bent form that folds of mutual pivot joint, announce No. 377689 novel patent case as Taiwan, mainly be to establish a joint seat in car body pedal end, be provided with the connecting frame of axis hole and circular hole in handle bottom extension one, wear joint seat and connecting frame by stud shaft, and joint seat is provided with the curved track groove, court divides into two block grooves in the curved track groove, reach and in the curved track groove of corresponding axis hole, wear bumping post location, other establish an extension spring with its two end respectively hook be against the stage casing of stud shaft and bumping post, the elastic pulling force that is formed by extension spring makes bumping post keep embedding block groove card fastening position when normality, when bumping post shifts out the block groove, promptly to be the center with the stud shaft do up or down slippage according to the curved track groove to bumping post, and bumping post is fastened in the block groove location that forms the scooter vertically-arranged or amount to by extension spring.

The above-mentioned scooter folding structure of commonly using, it only is fastened on the block groove with an extension spring with bumping post and forms single positioning action, lacks another and guarantees the secondary safety mechanism that locks easily to make us producing sense of insecurity.

In view of this, the purpose of this utility model provides a kind ofly to be had dual positioning action and opens up uprightly firm, and folds and operates the folding device of scooter easily.

For achieving the above object, solution of the present utility model is: a kind of folding device of scooter, front bar extends the support positioning seat that sets firmly at the pedal front end that is connected and forms the form that can transfer and fold, wherein the support of this front bar is provided with the pivot hole in the end, locate the moulding long slot bore on the pivot hole and establish connecting rod in support body inside, and form chute at upper side, one compresses seat and push pedal is installed in its inside, the outside respectively and ties with fixing bolt-lock; Pedal front end positioning seat is provided with axis hole in seat board lower end, both sides, the upside of axis hole forms deep-slotted chip breaker relatively, the front and back ends of deep-slotted chip breaker is distinguished moulding first groove, second groove up, the lower end axis hole docks with pivot with bracket end pivot hole wears knot, and the corresponding positioning seat deep-slotted chip breaker of support long slot bore wears a quick detach spigot that places sleeve pipe, establishes the sleeve pipe tension and be connected to the extension spring that compresses seat between sleeve pipe and connecting rod.

The folding device of above-mentioned scooter, wherein being provided with an ejection in the chute of this support, to compress seat and push pedal permanent upwards and can automatically reset spring.

After adopting such scheme, because the exhibition of the relative pedal of front bar, receipts location are to make above-mentioned support upwards snap in fixing reaching the packing of quick detach spigot with first and second groove of the sleeve pipe relative positioning seat of quick detach spigot, or give and move down the related pushing sleeve pipe that compresses of push pedal and break away from first and second groove, and rotatable is taken down the exhibits, and acts on easily to realize that dual location, exhibition are stood firm and folded operation.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 2 is a locking condition schematic diagram of the present utility model;

Fig. 3 makes schematic diagram for the stopper of separating of the present utility model;

Fig. 4 is the action schematic diagram () that folds of the present utility model;

Fig. 5 is the action schematic diagram (two) that folds of the present utility model.

As shown in Figure 1, the utility model is mainly tilted to extend a support 2 by front bar 1 and is connected with the positioning seat 4 of the relative moulding of pedal 3 front ends, wherein:

The support 2 inclination moulding of front bar 1 and be provided with pivot hole 21 in the end, locate moulding one long slot bore 22 on the pivot hole 21 and establish a connecting rod 23 in support body inside, form a chute 24 at upper side and compress seat 25 for one and be installed in inside, the outside respectively with gim peg 27 lock knots, and be provided with a spring 28 ejections with bottom land therebetween and compress seat 25 and upwards automatically reset with push pedal 26 perseverances with push pedal 26; The set positioning seat 4 of pedal 3 front ends is to establish an axis hole 41 in seat board lower end, both sides, the upside of axis hole 41 forms a deep-slotted chip breaker 42 relatively, the front and back ends of deep-slotted chip breaker 42 moulding up first groove 421, second groove 422, on support 2 and the positioning seat 4 location form that pivot connects mutually, lower end axis hole 41 is worn knot for 21 butt joints of pivot hole, support 2 end with a pivot 5, support 2 long slot bores 22 corresponding positioning seat 4 deep-slotted chip breakers 42 wear a quick detach spigot 6 that places sleeve pipe 61, establish an extension spring 7 at

sleeve pipe

61 and 23 of above-mentioned connecting rods, sleeve pipe 61 tensions are connected to compress seat 25.

Establish enforcement by above-mentioned design team, when scooter launches to erect fixedly with front bar 1 relative pedal 3, as shown in Figure 2, front bar 1 is that rotate in an axle center with the pivot 5 of pivot hole, support 2 end 21 butt joint positioning seats, 4 axis holes 41, make support 2 bottoms support the bottom surface of ending in positioning seat 4, simultaneously, the sleeve pipe 61 of the extension spring 7 pulling quick detach spigots 6 in the support 2 snaps in first groove 421 of front end along positioning seat 4 deep-slotted chip breakers, 42 upper limbs, form the fixing of first road, can pull again and press quick detach spigot 6 to compel to support positioning seat 4 clamp bracket 2, form the second road locking effect, and have double insurance safety effect.

When folding, as shown in Figure 3, can pull the relaxed spigot 6 of tearing open earlier, making positioning seat 4 and support 2 no longer be subjected to clamp supports, promoting push pedal 26 again moves down sleeve pipes 61 that compress seat 25 pushing quick detach spigots 6 with related inside and descends and break away from first groove 421, and bent support 2 rotations make this sleeve pipe 61 along deep-slotted chip breaker 42 slippages (as shown in Figure 4), after it bends fully, as shown in Figure 5, be subjected to quick detach spigot 6 sleeve pipes 61 of drops to be subjected to extension spring 7 drawings of support 2 inside again and when second groove 63 of involutory deep-slotted chip breaker 42 rear ends, to slip into automatically to fasten, fold state to fix it.
