Abstract

The utility model relates to an A-type folding device for a scooter frame of a scooter, which is composed of a folding mechanism composed of a quadrate pipe, an adjusting pipe, a bracket board, a connecting shaft, a shaft pipe, a lifting handle, a tension spring, etc. and a folding and locking mechanism composed of an adjusting screw rod, an adjusting screw cap, a shim seat, a cambered shim, a large spanner, etc. The folding and collecting inlaying states of a locking gap slot of the bracket board and the shaft pipe are used for realizing folding and unfolding states via the lifting handle, and the two states are locked by the folding and locking mechanism. The utility model has the advantages of reasonable and simple structure, safe use, portability and convenient storage, and besides, the utility model can be used for folding the scooter frame of the scooter conveniently and flexibly. The utility model is a replacing product for modern folding devices for scooters.

Description

Scooter vehicle frame A type folding device

The utility model relates to the folding device of scooter vehicle frame.

Scooter is to be made of slide plate, handle rack and wheel etc., by slide plate drive, the handle rack controlling party to, be a kind of light roadster that short distance distance and CRUX use that is beneficial to, in order to carry and to collect conveniently, Vehicle Frame Design must be become collapsible, can reduce volume like this.Traditional scooter is to pack in three cornues by front-wheel front fork parts, and the bar lower end becomes to be movably hinged, and packs into the big ring of embracing, put into then in three cornues, pull open the big ring of embracing during use, pull out bar, be wrenched the big ring of embracing at last and can use, folding when folding by bar lower end joint, be wrenched the big ring of embracing with regard to portability, so not only bothered but also dumb, its folding back shape is whole, volume is very big again, carries very inconvenient.

It is a kind of rational in infrastructure reliable that the purpose of this utility model all provides in the defective that overcomes prior art, folding convenient flexibly, carry and collect scooter vehicle frame A type folding device easily.

Embodiment of the present utility model is: this scooter vehicle frame A type folding device, comprise fold mechanism and fold locking mechanisms, the square tube of fold mechanism links to each other with adjustable pipe, the square tube bilateral symmetry is provided with the supporting plate that connects base plate, supporting plate and square tube are hinged and connected by connecting axle, and axially lock with jump ring, it is characterized in that it is the locking notch groove of axle center same curvature radius with the connecting axle that described supporting plate is provided with what fold two states, the square tube both sides are provided with and slide up and down the shape slotted eye, be provided with in the slotted eye can with the central siphon of locking notch groove tabling, the handle that can pull up and down along square tube, its fork footmuff that stretches in the square tube is contained on the central siphon, is provided with extension spring between central siphon and the connecting axle.

Described fold locking mechanisms comprises the adjusting screw(rod) that is set in the central siphon, and its two ends are overhanging outside supporting plate, and an end is spirally connected with regulating nut, and the other end is set with washer seat and arc pad and with the big spanner of pin riveted joint.

The utility model is owing to improve fold mechanism, the two kinds of chimerisms that fold of the locking notch groove of supporting plate and central siphon have been utilized, manipulation by handle realizes folding and expansion, and realize the locking of two states by fold locking mechanisms, it is rational in infrastructure, and is simple, folding convenient is flexible, safe and reliable, the collection that is easy to carry is the renewal product of modern scooter folding device.

Description of drawings.

Fig. 1 is the utility model stereochemical structure exploded view.

Fig. 2 is scooter contour structures schematic diagram (a beam tube deployed condition).

Below will be described in detail again the utility model embodiment by above-mentioned accompanying drawing:

Shown in Fig. 1-2, scooter vehicle frame A type folding device is made up of fold mechanism and fold locking mechanisms.

Described fold mechanism comprises and beam tube (18), the following adjustable pipe (6) that is connected with front fork (17), square tube (4) is welded at angle with adjustable pipe, the square tube bilateral symmetry is provided with the supporting plate (3) with base plate (8) welding, the two stands plate is fan shape, be hinged and connected by connecting axle (9) and square tube, axially lock with the jump ring (not shown), square tube can be folded to the base plate direction together with adjustable pipe.Supporting plate is provided with the locking notch groove (14) that folds two states on the sector of same curvature radius that with the connecting axle is the axle center, gap slot and base plate angle near base plate are 38 °, is 82 ° by the base plate gap slot with angle away from the gap slot of base plate, the angle position of gap slot has determined beam tube to launch the back and the formed angle of base plate also is 82 °, and folding back beam tube and base plate are parastate.The two sides of the adjacent supporting plate of square tube have and slide up and down the shape slotted eye, be provided with in the slotted eye can with the central siphon (2) of locking notch groove tabling.The square tube back has two parallel slots, handle (16) has two fork pin (1) to insert two parallel slots and stretches in the square tube and be sleeved on the central siphon (2), handle is moved up and down together can driving central siphon when the square tube slotted eye is pulled up and down, and be provided with extension spring (7) between central siphon and the connecting axle, the active force of extension spring is enough to make central siphon to be entrenched in the locking notch groove, when doing the folding action, must overcome tension spring tension by the pull-up handle, central siphon just can leave the locking notch groove, and can connecting axle be that the rotary folding action is done in the axle center this moment promptly.

Described fold locking mechanisms is the locking mechanism of beam tube when organizing work state and folding storage state, it is the assurance of scooter safety in utilization and folding reliability, this mechanism comprises the adjusting screw(rod) (11) that is set in the central siphon, its two ends are overhanging outside supporting plate, one end is spirally connected with regulating nut (5), the big spanner (10) that the other end is set with washer seat (13) and arc pad (12) and rivets with pin (15).

No matter the utility model is at deployed condition or folded state, after central siphon enters the locking notch groove, all can lock, being wrenched big spanner during locking gets final product, this moment, handle was inactive, desire to want to carry out the state conversion, decontroling big spanner earlier unlocks, the handle of ability pull-up at last makes central siphon break away from former gap slot can carry out the state conversion, central siphon is along the slippage of supporting plate sector during the state conversion, because the effect of extension spring makes central siphon slip into another locking notch groove automatically and promptly changes and finish, and can lock again after the conversion.
