A kind of folding device of scooter

Technical field

The utility model relates to scooter technical field, in particular to a kind of folding device of scooter.

Background technique

With increasing substantially for the income of residents, living standard is also obviously improved, and people are to amusement and recreation campaign Requirement it is also higher and higher, as a kind of sports apparatus scooter for integrating entertainment body-building, it both can be used as scooter The body building utensil of amusement and recreation, and can be used as interim traffic means of transport, and there is small in size, light weight and cost The advantages that low, easy to carry, and liked deeply by users, it is at home and abroad promoted the use of rapidly.

Data of China library discloses an a kind of entitled patent for Foldable skate-board, application No. is CN201720433781.2, applying date 2017.04.24, Publication No. CN206704400U, publication date 2017.12.05, This kind of Foldable skate-board includes faucet, spring, pulls set, connecting rod and mounting base, and the faucet is in hollow structure, institute It states connecting rod to be mounted in the faucet, the set that pulls covers on the faucet, and it is sliding that the faucet is equipped with first Row slot, described to pull set and be connected with connecting rod by pin, the pin passes through first slide slot, under the faucet End is hinged and connected with the mounting base, and limiting slot is additionally provided in the mounting base, and the limiting slot includes the rotation in arc-shaped The lower end of slot and the locating slot extended positioned at swivelling chute both ends to articulated section direction, the connecting rod is equipped with limited post, the dragon Head tube is equipped with the second slide slot, and the limited post passes through second slide slot and is stuck in the limiting slot.Although this kind is rolled over The faucet of stacked scooter is foldable, but its folding mode is that upward lifting hand is helped pull a cart, since scooter is lighter, institute By need to be stepped on foot when lifting scooter or hand pressure by way of give scooter apply a downward pressure, make scooter stablize exist Ground prevents from lifting scooter from ground during lifting, leads to not folding scooter, the mode of this kind of folding handle-bar stem It is inconvenient.

Utility model content

The purpose of the utility model is to provide it is a kind of be not required to provide additional stabilization power can folding scooter faucet cunning Wooden handcart folding device.

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

A kind of folding device of scooter, including attachment base and faucet, faucet is by being fixed in the connection of its end Head is hinged with attachment base, is provided with the traveller being slidably connected with it in the faucet, traveller be from top to bottom arranged there are two with The identical waist-shaped hole of glide direction, upside are the first waist-shaped hole, and downside is the second waist-shaped hole, are plugged with and are used in the second waist-shaped hole Be articulated and connected the second pin shaft of head and attachment base, is plugged with first pin shaft affixed with faucet, the first waist in the first waist-shaped hole Third pin shaft is arranged in the upside of type hole, and third pin shaft and the movable sleeve being socketed on the outside of faucet are affixed, movable sleeve and faucet It is slidably connected, faucet offers the third waist-shaped hole with the cooperation of third pin shaft, is arranged between the first pin shaft and third pin shaft There is the spring being socketed on the outside of traveller, the lower end of traveller is provided with the 4th pin shaft, and the 4th pin shaft is parallel with the second pin shaft, attachment base It is provided with the arc groove that the 4th pin shaft surrounds the second pin shaft moving in rotation, arc groove is provided with multiple radial directions for being directed toward the second pin shaft Groove, radial groove are used to position the relative angle of faucet and attachment base.Since the first pin shaft is fixedly connected with connector, the Spring above the one pin shaft thrust upward to third pin shaft, it is described to connect with traveller lower end since third pin shaft is connected with traveller The 4th pin shaft connect is connected in radial groove, and faucet is fixed at this time, downward push movable sleeve, third pin shaft compressed spring, Traveller moves downward, and the 4th pin shaft of traveller lower end is deviate from from radial groove, rotates faucet, unclamps movable sleeve, faucet It is rotated centered on the second pin shaft, when turning to next radial groove, under the thrust of spring, pushes third pin shaft Movement, the traveller connecting with third pin shaft move in the same direction, and the 4th pin shaft of traveller lower end is connected in radial groove, to realize dragon The positioning of head tube again.

The connector is set as convex arc close to the end of attachment base side, and attachment base is provided with the concave arc with convex arc cooperation. Interfere when the pairing setting of convex arc concave arc prevents connector from rotating with pedestal.

The movable sleeve is extended with guide sleeve close to one end of connector, and the guide sleeve opens up and connector upper end shape The inner cavity to match, when the 4th pin shaft is connected in radial groove, one of the inner cavity of guide sleeve front end and connector upper end Point overlap joint, the guide sleeve when movable sleeve is moved along leading tube axis direction from guiding and positioning function.Guide sleeve is in movable sleeve Guidance positioning action from when movement keeps the movement of movable sleeve more accurate and reliable.

There are two the radial grooves, and one is vertically set vertical radial groove, another is horizontally disposed Horizontal radial groove.

It is opened up and the comparable groove of radial groove at corresponding 4th pin shaft of the connector.When connection area of bed determines, If connector is not provided with corresponding groove, the 4th pin shaft is interfered when being clamped into radial groove with connector in order to prevent, is needed Increase the relative size of attachment base, guarantees that connector will not be arranged in the range of arc groove and radial groove, when connector is set When setting groove, the periphery of connector be may be disposed between arc groove and radial groove, and groove is arranged in the connector The size of entire folding device is reduced, on the other hand, since the 4th pin shaft can be hit in folding process with radial groove, is held Easily-deformable damage when the 4th pin shaft is connected in radial groove, while being also clamped so corresponding groove is arranged in connector In connector, i.e., supporting point is increased to the 4th pin shaft, reduce the support force of each supporting point, improves the 4th pin shaft Service life.

Compared with prior art, the utility model has the beneficial effects that: can directly be rolled over by directly pressing movable sleeve Folded faucet, method simple practical.
