Detailed Description

As shown in fig. 1-8, an anti-pulling structure for a handle stem 2 of a scooter comprises a front fork stem 1 and a handle stem 2 capable of stretching and self-locking at an extending position and inserted in the front fork stem 1, wherein the front fork stem 1 is used for mounting a front fork, and the handle stem 2 is used for mounting a handle; the bicycle handlebar stem limiting device is characterized by further comprising a limiting bush 3 sleeved at an upper port of the front fork stem 1, wherein the limiting bush 3 is arranged between the front fork stem 1 and the handlebar stem 2. The self-locking structure specifically comprises: the marble 4 is arranged in the first radial hole 21 of the handle vertical pipe 2 and can advance and retreat through an elastic piece 5, and the elastic piece 5 is a V-shaped spring; the limiting bush 3 and the front fork vertical pipe 1 are respectively provided with a second radial hole 31 and a third radial hole 11 with coincident openings; when the front fork vertical pipe 1 extends to three radial holes to coincide, the marbles 4 automatically pop out to keep the handle vertical pipe 2 locked with the front fork vertical pipe 1. In order to ensure the structural connection reliability, the periphery of the second radial hole 31 of the limiting bush 3 is provided with a convex limiting outer edge 32, and the limiting outer edge 32 is sleeved in the third radial hole 11. Thus, the stopper bush 3 is axially stopped from the front fork stem 1. Furthermore, the upper end of the front fork vertical pipe 1 is also provided with a hoop type pipe clamp 6 for pressing the upper port of the front fork vertical pipe 1 and limiting the limiting bush to be incapable of rotating.

The anti-pulling-off structure specifically comprises: the plug 7 is arranged at the lower end of the handle vertical pipe 2, and the plug 7 comprises an elastic lug 71 which is stressed to deform inwards so as to enter the front fork vertical pipe 1;

the plug inner plug 8 is arranged in the plug 7 and used for limiting the elastic lug 71 from deforming inwards;

when the handle vertical pipe 2 extends upwards to the maximum distance, the elastic lugs 71 prop against the limiting bushes 3, so that the handle vertical pipe 2 is limited from being pulled out.

Furthermore, the plug 7 is clamped and fixed in the handle vertical pipe 2; and the inner plug 8 of the plug is clamped and fixed in the plug 7. The handle vertical pipe 2 is provided with two fourth radial holes 22 which are oppositely formed, two sides of the middle end of the plug are provided with first buckles 72, and the first buckles 72 are meshed with the fourth radial holes 22; a clamping hole 73 is formed in one side wall of the plug 7, and a second buckle 81 meshed with the clamping hole 73 is arranged on the plug inner plug 8.
