Description

Quick-release type folding handlebar stand

Technical Field

The utility model relates to a bicycle accessory field especially relates to a folding stick of quick detach formula is found.

Background

The handlebar stem is commonly called as a bicycle handlebar stem, the running direction of the bicycle is directly controlled, and the control flexibility of the handlebar stem is directly related to the height and the length of the stem.

The vertical tube and the frame are matched to form the total length of the upper tube. Note that this length is not necessarily equal to "top frame TT value + riser length" because the riser angle exists and the positive and negative mounting results in different heights, thereby affecting the overall top tube length and actually requiring measurement to obtain.

At present folding bicycle handlebar can not angle regulation, leads to folding back space still very big, and can not adjust handlebar length, leads to child when learning to the car, and the arm is shorter, and inconvenient support is easily fallen down, and the commonality is poor, for this reason, we propose a quick detach formula folding handle and stand to solve above-mentioned problem.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a folding stick of quick detach formula is found, including bracing piece 6 and bolt 5, surface welded fastening has connector 1 on bolt 5, surface welded fastening has riser 9 inside connector 1, bolt 5 is located connector 1 front side, bolt 5 rear end runs through connector 1 front surface and riser 9 and extends to connector 1 rear side, both ends are all rotated around riser 9 and are connected with rotation go-between 10, the rotation go-between 10 left and right both ends of different sides welded fastening have connecting rod 2 respectively, connecting rod 2 keeps away from connector 1's one end and all welded fastening has connecting sleeve 3, one side that connecting sleeve 3 kept away from connector 1 all is provided with handle 4, the one end that handle 4 is close to connecting sleeve 3 extends to in connecting sleeve 3 respectively.

The outer surface of one end of the handle 4 close to each other is processed with screw threads, the inner annular side surface of the connecting sleeve 3 is processed with screw thread grooves, the handle 4 is connected with the connecting sleeve 3 through the screw threads and the screw thread grooves, so that the handle 4 can rotate in the connecting sleeve 3, one end of the connecting sleeve 3 close to each other is fixed with a circular plate 7, the end part of the handle 4 inside the connecting sleeve 3 is fixed with a limit plate 12, one side of the circular plate 7 close to each other is provided with a square rod 11, the square rod 11 respectively penetrates through the circular plate 7 and the limit plate 12 and extends into the handle 4, the surface of the limit plate 12 is provided with a square hole, one side surface of the circular plate 7 far away from each other is welded with a spring 13, the square rod 11 penetrates through the spring 13 and extends into the handle 4, one end of the spring 13 close to each other is welded and fixed with a pull ring, the square hole is matched, the rear surface of the connector 1 is fixed with a threaded limiting sleeve 8, a right thread groove is machined in the annular side face in the threaded limiting sleeve 8, the rear end of the bolt 5 penetrates through the rotary connecting ring 10 and the vertical plate 9 and extends into the threaded limiting sleeve 8, the rotary connecting ring 10 is convenient to limit, a limiting plate is fixed on a square rod 11 at the right end of the spring 13, and the caliber of the limiting plate is larger than that of the spring 13.
