[0020] The handlebar folding structure of this creation is Figure 1 and Figure 2 As shown, it is composed of a tube body 10 and grip tubes 20 respectively installed at both ends of the tube body 10;
[0021] The detailed composition of this work is as follows: Figure 2 , Figure 3 and Figure 4 As shown, the two ends of the tube body 10 are respectively provided with a front tube section 11 for connecting the grip tube 20, and the front tube section 11 is formed with a pivot groove 12 passing through the axis of the front tube section 11 corresponding to the end of the grip tube 20, and the axis of the front tube section 11 is formed with a receiving hole 13 connected to the pivot groove 12, and the ends of the front tube section 11 are respectively formed with pivot holes 14 passing through the two side walls of the pivot groove 12, for respectively using a pivot shaft 15 to penetrate the relative grip tube 20, and the front tube section 11 is formed with a long pull groove 16 extending along the axis at the connection between the pivot groove 12 and the receiving hole 13. The frontal tube section 11 is provided with a stop mechanism 17 that can selectively limit the grip tube 20. The stop mechanism 17 uses an elastic member 181 and a guide rod 182 that penetrates the elastic member 181 to be sequentially provided in the accommodating hole 13. One end of the guide rod 182 is provided with a stop rod 19 that supports the elastic member 181. The stop rod 19 is slidably provided in the long pull groove 16 of the frontal tube section 11 under the action of the elastic member 181, so that the stop rod 19 is affected by the elastic member 181 to generate a pre-force to reset relative to the grip tube 20, so as to limit the movement of the grip tube 20.
[0022] The grip tube 20 has a pivot ear 21 corresponding to the pivot groove 12 of the frontal tube section 11. The pivot ear 21 of the grip tube 20 has a pivot hole 22 for the pivot shaft 15 of the frontal tube section 11 to pass through, so that the grip tube 20 can selectively pivot relative to the frontal tube section 11 at both ends of the tube body 10 with the pivot shaft 15 as the axis. Furthermore, a horizontal slot 25 and a vertical limit groove 26 are formed on the periphery of the pivot ear 21 of each grip tube 20 for the selective engagement of the anti-rotation rod 19 of the stop mechanism 17 (such as Figure 4 and Figure 6 As shown in FIG. 1 , the upper edge of the horizontal slot 25 has a limiting protrusion 250 for limiting the upward pivoting of the grip tube 20 relative to the front tube section 11 of the tube body 10. The pivot ear 21 of the grip tube 20 forms an arc guide surface 27 between the horizontal slot 25 and the limiting groove 26, so that the grip tube 20 can rotate smoothly (as shown in FIG. 1 ). Figure 5 As shown), the grip tube 20 is provided with a soft grip cover 28 for the rider to hold; thus, the grip tube 20 at both ends of the tube body 10 can be selectively unfolded horizontally or folded downward by moving the anti-rotation rod 19 of the stop mechanism 17, thereby forming a handlebar folding structure.
[0023] The handlebar folding structure is used in actual operation. Figure 1 and Figure 4As shown, in normal unfolding use, the grip tube 20 at both ends of the tube body 10 is unfolded upward and horizontally, so that the horizontal slot 25 on the pivot ear 21 of the grip tube 20 can correspond to the stop mechanism 17 of the tube body 10 relative to the front tube section 11, and the anti-rotation rod 19 of the stop mechanism 17 is relatively embedded in the horizontal slot 25 due to the resetting effect of the elastic member 181, and the anti-rotation rod 19 is supported by the resetting effect of the elastic member 181 and will not fall out of the horizontal slot 25 at will, so that the grip tube 20 can be horizontally fixed at both ends of the tube body 10 and will not pivot upward or downward, so that the rider can operate the transportation tool through the handlebars.
[0024] When the handlebar needs to be folded, Figure 5 and Figure 6 As shown, the anti-rotation rod 19 of the stop mechanism 17 located in the long pull groove 16 on the forehead tube section 11 at both ends of the tube body 10 is pressed toward one side of the forehead tube section 11, so that the anti-rotation rod 19 is out of the range of the horizontal slot 25 of the grip tube 20, and then the grip tube 20 is pivoted downward, so that the anti-rotation rod 19 can move along the arc guide surface 27 of the pivot ear 21 of the grip tube 20 to the limiting groove 26, and the anti-rotation rod 19 is supported by the resetting and pushing action of the elastic member 181, and will not fall out of the limiting groove 26 at will, so that the grip tube 20 can be folded downward, thereby achieving the purpose of reducing the width and volume of the handlebar.
[0025] From the above description, it can be known that since the handlebar folding structure of the present invention can utilize the stop mechanism 17 in the front tube section 11 at both ends of the tube body 10 to selectively limit the relative grip tube 20, thereby selectively limiting the grip tube 20 in the horizontal unfolded position or the vertical folded position by operating the anti-rotation rod 19 of the stop mechanism 17, the handlebar width can be effectively and selectively reduced, which has the effect of facilitating operation, and can effectively reduce the volume of transportation and packaging, and can be easily carried outside. In addition to being convenient for packaging and carrying and loading, it can also reduce the packaging material and transportation costs, greatly improving its practicality.
