In order to solve the above problems, an object of the present invention is to provide a pillar folding structure that can unlock a pillar quickly and can fold the pillar only by lifting the pillar after the pillar is unlocked.

In order to achieve the purpose, the utility model adopts the following technical scheme: the bicycle comprises a bicycle frame, an upright post movably arranged on the bicycle frame and a handrail arranged at the upper end of the upright post, wherein a limiting seat is fixedly arranged on the side wall of the bicycle frame, the upright post is inserted into the limiting seat and connected with the limiting seat through a connecting shaft, and the connecting point is a shaft point A; the folding structure also comprises a locking component arranged at the lower part of the upright post;

the upright column descends relative to the shaft point A to the bottom of the limiting seat, the lower end of the upright column is embedded into the bottom of the limiting seat, the locking assembly locks the upright column and the limiting seat, and the upright column is fixed relative to the shaft point A;

the stand goes upward to the lower extreme relative pivot point A and breaks away from spacing seat bottom, and locking Assembly is the unblock state, and the stand can be followed pivot point A rotates.

In the technical scheme, the upright post can rotate along the shaft point A relative to the limiting seat, the locking component is arranged at the lower part of the upright post, and the locking component is of a quick-release structure; the stand inserts to be not hard up in the spacing seat, acts on locking Assembly with the relative spacing seat locking of stand, makes the stand upright to supply the user to use. When the locking assembly is in an unlocking state, if the locking assembly does not move, the displacement of the upright post in the horizontal direction is still limited by the locking assembly, and the upright post is still in a locking state after the unlocking operation of a user is finished, so that the locking mechanism is safer; the upright post is pulled upwards, so that the elastic component in the locking assembly is not limited to the upright post any more, and the locking assembly is not propped against the limiting seat any more, so that the upright post and the locking assembly are turned to a folded state along the axial point A.

Preferably, an opening is formed in the other side wall, opposite to the locking component, of the limiting seat; the lower part of stand is equipped with waist type hole, the connecting axle passes waist type hole makes stand and spacing seat rotatable coupling to make the stand can be in when locking Assembly is the unblock state the opening rotates. In the technical scheme, the arrangement of the waist-shaped hole facilitates the upward unlocking or downward fixing of the upright post relative to the limiting seat along the connecting shaft, and the rotation of the connecting shaft in the waist-shaped hole is more flexible relative to the round hole and is matched with the realization of the folding function; the opening on the limiting seat is arranged to match with the rotating track of the upright post.

Preferably, the limiting seat is fixed on the frame through a connecting shaft, and the shaft point a is a point position where the connecting shaft penetrates through the frame. Among this technical scheme, spacing seat is screwed up through the connecting axle and is fixed in on the frame, so set up, and whole spacing seat and stand can both be more quick convenient dismouting on the frame.
