Description

Folding bicycle

Technical Field

the utility model relates to the technical field of bicycles, especially, relate to a folding bicycle.

Background

The folding bicycle of prior art back front fork still can rotate wantonly, and the direction of front wheel can rotate along with the front fork wantonly promptly, and it will be very inconvenient when the user needs to promote the bicycle after folding and remove like this, can not fine grasp the direction of advancing.

Disclosure of Invention

The utility model discloses the technical problem that will solve is: provides a folding bicycle with a front fork incapable of rotating freely after folding.

The utility model adopts the technical proposal that: the utility model provides a folding bicycle, includes head pipe, cover establish the head intraductal front fork, rotate the front wheel of connecting in the front fork lower part and connect the handlebar on front fork upper portion through handlebar scray, is equipped with first connecting piece on the handlebar, is equipped with the second connecting piece on the head pipe, and when handlebar scray expandes, first connecting piece and second connecting piece cooperation are connected.

Preferably, the first connecting piece is a limiting piece, the second connecting piece is a limiting piece, and a limiting groove for the limiting piece to be embedded into and rotate for limiting is formed in the limiting piece.

Preferably, the limiting part sequentially comprises a limiting pin cover, a limiting pin and a pressure spring.

Preferably, the two sides of the limiting block are inclined planes.

Compared with the prior art in the structure more than adopting, the utility model has the advantages of it is following: the connecting pieces are arranged on the head pipe and the handlebar, so that the handlebar can be connected and matched with the head pipe after being folded, the handlebar cannot rotate randomly, the front wheel cannot rotate randomly, and the user can more conveniently push the folded bicycle.

The limiting part is matched with the limiting groove to limit, so that the structure is simple, and the limiting is reliable.

The limiting piece is formed by the pressure spring and the limiting pin, so that the handle can be rotated to enable the limiting pin to be embedded into the limiting groove even if the handle is not aligned at the beginning.

The two sides of the limiting block are provided with inclined planes, so that the limiting pin can conveniently rotate from two sides to enter the limiting groove.

Detailed Description

The present invention will be further described below with reference to specific embodiments, but the present invention is not limited to the following specific embodiments.

A folding bicycle comprises a bicycle body, a head pipe 1 fixed in front of the bicycle body, a front fork 2 sleeved in the head pipe 1, a front wheel 3 rotatably connected to the lower part of the front fork 2, and a handlebar 5 connected to the upper part of the front fork 2 through a handlebar folder 4, wherein under normal conditions, the handlebar and the front fork can rotate simultaneously so as to drive the front wheel arranged on the front fork to rotate and adjust the direction;

Now set up first connecting piece 6 on handlebar 5, set up second connecting piece 7 on head pipe 1, can be through first connecting piece and second connecting piece with head pipe 1 and handlebar locking like this, make the handlebar can not rotate wantonly, and then make front fork and front wheel can not the adjustment direction, realize the direction locking, exchange the position of first connecting piece 6 and second connecting piece 7 equally, set up second connecting piece 7 on handlebar 5 promptly, set up first connecting piece 6 on the head pipe 1, the locking function also can be realized to the same, wherein:

The first connecting piece 6 comprises a limiting pin cover 11, a limiting pin 12 and a pressure spring 13, a hole is formed in the handlebar, and the three parts are sequentially installed in the hole to form a limiting piece 8;

The second connecting piece comprises a limiting block 9, a limiting groove 10 is formed in the middle of the limiting block 9 and used for enabling a limiting pin 12 to be embedded and locked, and inclined planes 14 are formed on two sides of the limiting block 9, so that the limiting pin 12 can be conveniently embedded into the limiting groove 10 from two sides in a rotating mode.

finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
