Detailed Description

The present invention will be further described with reference to the following specific examples.

As shown in fig. 1-3, the utility model discloses a follower pole setting folding mechanism rides instead of walk, including setting up at the anterior preceding crotch 7 of scooter frame 10, preceding crotch upper portion sets up pole setting structure 1, and the front portion of preceding crotch sets up the preceding fender 6 that can luffing motion adjusting position, and the pole setting structure can overturn folding laminating frame up end downwards, and the folding or the expansion state of pole setting structure is locked by preceding fender, and the regulation of preceding fender is locked by a switch structure.

In one embodiment, the switch structure includes a locking tab 9 provided on the front fork, which can lock or unlock the front fender from the pole structure. The locking pressing sheet is connected to the front fork frame through a pin shaft 3, the end of the lower portion of the locking pressing sheet, into which the pin shaft is inserted, is of a cam structure 4, and the protruding end of the cam structure is in a mud guard locking state when abutting against the rear end of the front mud guard. The hinge pin is used as a rotating fulcrum to rotate the locking pressing piece upwards, the cam structure is changed to abut against the rear end face of the front fender, the space of the rear end of the fender is released, the fender can be pressed downwards, the fender is separated from the locking state with the pull rod structure, and the whole upright rod structure can be completely unlocked to adjust the state.

Wherein in order to facilitate the cam structure to rotate, the front fork frame is provided with an arc-shaped surface and a space for avoiding the cam structure to rotate.

Wherein in order to facilitate the locking pressing sheet to be easily pulled, the tail end of the locking pressing sheet forms an upturning surface, and the locking pressing sheet is convenient for a user to stir.

Preceding fender passes through another round pin axle 5 and connects preceding crotch, and for the convenience of convenience preceding fender remains the tensioning state throughout, this round pin hub connection extension spring, the location axle that sets up crotch lower part in the front is connected to the other end of extension spring, and it can keep locking pole setting structure to ensure to reset again after the preceding fender unblock.

In one embodiment, the vertical rod structure comprises a vertical rod frame, two clamping grooves 11 are respectively arranged on two sides of the lower portion of the vertical rod frame and are respectively an unfolding positioning clamping groove and a folding positioning clamping groove, a locking clamping block 12 is arranged at the rear end of the front fender, and the front fender can be swung to adjust and change the position of the locking clamping block so that the locking clamping block can be clamped into any clamping groove.

Specifically, the upper end face of the locking clamping block is a downward inclined face, and an inclined face matched with the locking clamping block is arranged in the clamping groove, so that the locking clamping block can be smoothly and quickly clamped into the clamping groove.

Specifically, limit stops 13 are further arranged on two sides of the rear portion of the front fork frame, can effectively prevent the vertical rod structure from excessively deflecting, are limited at the rear end, ensure that multiple directions of the vertical rod structure are reliably and strictly limited in the unfolding state, and enable the locking state to be more reliable.

Specifically, the middle part of pole setting frame forms fretwork 2, and when the pole setting structure of being convenient for was transferred and is emptyd, the anterior steering support of fork frame before the fretwork portion can break through and the frame makes the pole setting structure keep flat completely.

Preferably, an outer vertical rod is arranged at the upper part of the vertical rod frame, an inner vertical rod capable of extending out or retracting into the outer vertical rod is arranged on the outer vertical rod, and a locking ring buckle is arranged at the joint of the outer vertical rod and the inner vertical rod. The upper portion of pole setting structure sets up handle bar structure, and wherein the handle bar can turn over backward and be 90 degrees rather than the main part.

The utility model discloses when needing folding pole setting structure, at first need unblock switch structure, for example the locking preforming that provides in the embodiment lifts the preforming, makes the cam structure rotate, and the pressure of fender rear end before the release, fender can be pressed down before this moment, and its terminal locking fixture block breaks away from the draw-in groove of pole setting structure, and the pole setting structure can be fallen down, until parallel with the frame. The fender makes its resilience card go into folding draw-in groove before releasing this moment, presses the preforming downwards again, makes the cam structure rotate, and the fender rear end before pushing up again makes it can not pushed down by reliable locking fender position before, and the pole setting structure after folding like this is by multiple spacing, can't expand easily, ensures the reliable and stable nature of fold condition, the transport of being convenient for. If the folded state is required to be opened, the operation is sequentially performed in the reverse direction, and finally the reliable locking of the unfolded state is ensured by pressing down the locking pressing sheet, and the rest operation steps are not described again.

The upright rod structure is folded on the frame, and the shape of the upright rod structure is regular, so that the whole structure is stable and reliable. The occupied space is greatly reduced, and the carrying and the storage are convenient.

It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications can be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
