Multi-section pipe sleeve structure

Abstract

The invention provides a multi-section pipe sleeve structure. The problems that multi-section pipe sleeve structures are poor in locking effect, have potential safety hazards and are inconvenient to adjust can be solved. The bottom of an inner pipe is sleeved with the inner circle of the top of an outer pipe and can conduct rectilinear translation in the outer pipe. The top of the inner pipe is fixedly connected with a handlebar vertical seat. The upper side and the lower side of the pipe wall of the outer pipe are each provided with a locking hole. A self-locking limiting mechanism is installed at the bottom end of the inner pipe and can be sleeved with the inner circle of the top of the outer pipe along with the inner pipe. The self-locking limiting mechanism is provided with a spring bolt capable of sliding in the radial direction. The spring bolt can be matched with the locking holes, and thus the outer pipe and the inner pipe are relatively locked and limited or can move. A triggering mechanism in the handlebar vertical seat can drive a guide mechanism in the inner pipe to vertically move and trigger the self-locking limiting mechanism to vertically act, and meanwhile vertical displacement is converted into radial horizontal movement of the spring bolt, so that locking or unlocking between the spring bolt and the locking holes is triggered, and position locking or telescopic adjustment between the outer pipe and the inner pipe is achieved.

Description

technical field [0001] The invention relates to the structural field of small folding vehicles, in particular to the technical field of structures for folding bicycles and folding scooters, in particular to a multi-section pipe sleeve structure. Background technique [0002] The front fork parts of current folding bicycles or folding electric vehicles or folding scooters mostly use multi-section sleeve structure to realize telescopic folding, while the existing multi-section sleeve structure is to set the upper inner tube in the lower outer tube The walls of the inner tube and the outer tube are provided with matching vertical concave-convex grooves to achieve vertical linear movement, and at the same time, the outer tube is radially adjusted by the clamping adjustment device assembled on the outer circumference of the outer tube. Clamping makes the outer tube produce rigid deformation to achieve the purpose of controlling the outer tube to engage the inner tube and finally ...
