Folding stand column locking mechanism

Abstract

The invention discloses a folding stand column locking mechanism which comprises an upper lock body and a lower lock body which are connected in a hinged mode, the joint end face of the upper lock body and the lower lock body is a concave-convex matching face, the concave-convex matching face is provided with a magnetic attraction part, the peripheral side face of the upper lock body is provided with a first transverse groove, the peripheral side face of the lower lock body is provided with a second transverse groove, and the first transverse groove is provided with a magnetic attraction part. The first transverse groove and the second transverse groove are in butt joint when the upper lock body and the lower lock body are vertically connected, an outer locking sliding block sliding along the second transverse groove is arranged in the second transverse groove, a spring limiting ball is arranged in the second transverse groove, the outer locking sliding block is provided with at least two locking ball sockets matched with the spring limiting ball, and the locking ball sockets are arranged in the outer locking sliding block. And when the outer locking sliding block slides in the second transverse groove and is partially embedded into the first transverse groove, the upper lock body and the lower lock body are prevented from being opened. The lock comprises reliable locking of the upper lock body and the lower lock body in the vertical butt joint state, the outer side face structure of the lock body is simplified, and operation is easy and convenient.

Description

technical field [0001] The invention relates to a folding locking mechanism, in particular to a folding column locking mechanism applied to a folding bicycle and a folding scooter. Background technique [0002] In folding bicycles and folding scooters, in order to make the space after folding smaller, the front column is usually designed as a foldable segment structure. In the segmented position of the column, a folding locking mechanism is required to realize the bending and erection of the column. The existing locking mechanism includes an upper lock body and a lower lock body, the upper lock body and the lower lock body are connected together by a coaxial hinge shaft, and there is a folding lock on the opposite side of the hinge side of the upper lock body and the lower lock body. The locking chain, the two ends of the folding locking chain are respectively connected with the upper locking body and the lower locking body. After opening the locking chain, the upper and lo...

Problems solved by technology

Since this structure can be bent by applying force to the column, in order to prevent the folding locking chain from opening due to accidental force on the column during driving and causing potential safety hazards, it is also necessary to set up a safety device to prevent opening. The device is connected to the outer side of the upper lock body and the lower lock body, making the structure of the outer side of the column cumbersome
