Utility model content

The purpose of the utility model is to provide a kind of simple folding device of scooter of folding mode.

In order to realize above-mentioned purpose of utility model, the following technical side that a kind of folding device of scooter of the utility model uses Case:

A kind of folding device of scooter, including slide plate, slide plate front side are foldable base, and foldable base middle part is along slide plate length direction The first groove is offered, the first pin shaft is horizontally arranged in first groove, first pin shaft both ends are plugged in first In the side wall of groove, it is socketed with swivel cougling in the middle part of first pin shaft, the swivel cougling is set between the first groove and leads to It crosses the first pin shaft and foldable base is rotatablely connected, the swivel cougling offers first through hole, the first through hole along its length In be plugged with standpipe, standpipe is stretched out in upwards on the outside of first through hole, and the standpipe offers symmetrical waist-shaped hole along axis, described Waist-shaped hole is located in first through hole, and the swivel cougling offers through-hole corresponding with waist-shaped hole, the through-hole of the swivel cougling With the second pin shaft is plugged in waist-shaped hole, on second pin shaft both ends stretch out in the outside of swivel cougling and can be in waist-shaped holes Lower movement, is also socketed with first sleeve on the outside of the swivel cougling, and the first sleeve upper end edge axis offers symmetrical the The end of two grooves, second pin shaft is set in the second groove, and the first sleeve upper end is connected with the second casing, described The both ends of second pin shaft are limited in the second groove by the second lower end, are also socketed with the one of plug in the middle part of second pin shaft End, the plug other end are arranged towards foldable base and are protruding with lock pin, and the lock pin passes through first through hole and stretches out in swing On the outside of connector, the lock pin is slidably connected with first through hole end, offers in the middle part of the plug for avoiding the first pin shaft Second through-hole of strip is provided with compressed spring in second through-hole, and described compressed spring one end is crimped on the second through-hole Bottom hole, the other end is connected to the first pin shaft lower surface, and it is recessed that first groove is provided with multiple radial directions for being directed toward the first pin shaft Slot, the lock pin are inserted into radial groove to limit the relative angle between standpipe and foldable base under the promotion of compressed spring. Lifting first sleeve upwards, since the second pin shaft is set in the second groove, so the second pin shaft is under the thrust of first sleeve It is moved upwards along waist-shaped hole, and drives and moved with the plug connecting, since the first pin shaft is not subjected to displacement, so plug is moving While, the compressed spring in the second through-hole is compressed, when the lock pin of plug lower end is detached from radial groove, to the side of first sleeve Face applies pressure, and first sleeve drives swivel cougling to rotate around the first pin shaft, when lock pin moves at other radial grooves, pine First sleeve is opened, lock pin is inserted into radial groove under the action of compressed spring elastic force, to realize between standpipe and foldable base The change of relative angle.

The slot bottom of first groove is concave arc, and swivel cougling lower end outer surface is the convex arc cooperated with concave arc.It is convex The pairing of arc and concave arc is arranged, and interferes when preventing swivel cougling from rotating with the slot bottom of foldable base.

There are two the radial grooves, vertical radial groove and horizontally disposed horizontal radial respectively straight down Groove.

The slot bottom of the first groove between the horizontal radial groove and vertical radial groove is protruding with number around the first pin shaft Guide rail, swivel cougling lower end outer surface offers the guide groove to match with guide rail.The guide rail and guide groove are matched It closes, it is more stable when making swivel cougling around the rotation of the first pin shaft.

The side that the vertical radial groove is located at slide plate raises upward and has first boss, and the swivel cougling is located at slide plate The outer surface of side be recessed inwardly and have third groove, the third groove matches with first boss, and the third groove is used In the extreme position that limitation standpipe is rotated towards foldable base side.It is abutted by swivel cougling one end with first boss, while lock pin It is inserted into vertical radial groove, so that the positioning of swivel cougling is more stable, so that the standpipe connecting with swivel cougling is in perpendicular It is more stable when straight state.

Circumferentially arranged 4th groove of the inner ring of the first sleeve upper end, the outer ring of second lower end is circumferentially It is protruding with the second boss to match with the 4th groove, the second boss, which is connected in the 4th groove, realizes first sleeve and the The connection of two casings.By plug connection between first sleeve and the second casing, the cooperation of second boss and the 4th groove makes first Casing and the second casing connection it is more firm.

There are columned pillar, the compressed spring gap socket in second through-hole lower surface towards the first pin shaft protrusion In outside pillar.Pillar keeps compressed spring positioning more accurate.

Compared with prior art, the utility model has the beneficial effects that: by lifting first sleeve upwards, make lock pin with Radial groove is detached from, and rotation first sleeve to lock pin moves to another radial groove, and unclamping first sleeve makes lock pin be inserted into diameter It is positioned after to groove, to realize the folding of scooter upper riser.
