[0027] Embodiment 1:

[0028] The preferred embodiment of the adjustable handlebar joint of the bicycle provided by the present utility model is as Figures 1 to 7 shown: An adjustable handlebar joint of a bicycle includes a frame branch pipe 1, a telescopic frame 2, and a connecting plate 3. The frame branch pipe 1 is sleeved on the outer wall of the telescopic frame 2. An adjustment and limit mechanism 5 is provided between the top end of the connecting plate 3 and the telescopic frame 2. A handlebar 4 is fixedly installed at the top end of the connecting plate 3;

[0029] The adjustment and limit mechanism 5 includes a rotating shaft 501 and a connecting shaft 502. The rotating shaft 501 penetrates through the telescopic frame 2, and the outer wall of the rotating shaft 501 is rotatably connected to the telescopic frame 2 through a first bearing. A shaft groove 503 is opened at one end of the rotating shaft 501. The connecting shaft 502 is inserted into the shaft groove 503. A pull plate 507 is fixedly installed at one end of the connecting shaft 502. A rod groove 505 is opened at the other end of the connecting shaft 502. A limiting rod 504 is fixedly installed on the inner wall of the shaft groove 503. The limiting rod 504 is inserted into the rod groove 505. A spring 506 is wound around the outer wall of the limiting rod 504. One end of the spring 506 is fixedly installed on the inner wall of the shaft groove 503, and the other end of the spring 506 is fixedly installed at the other end of the connecting shaft 502. A pin block 508 is fixedly installed on the inner side of the pull plate 507. A pin groove 509 is opened on one side of the telescopic frame 2. The pin block 508 is inserted into the pin groove 509.

[0030] Specifically, in the above technical solution, the pull plate 507 is pulled to move outwards. The pull plate 507 drives the pin block 508 to move, so that the pin block 508 disengages from the pin slot 509 at the current position. The pull block also drives the connecting shaft 502 to move outwards from the shaft slot 503. The connecting shaft 502 stretches the spring 506. When the pin block 508 disengages from the pin slot 509, the pin block 508 no longer limits the connecting shaft 502 of the rotating shaft 501. At this time, the connecting plate 3 can be rotated to adjust the angle of the handlebar 4 on the connecting plate 3. After the angle adjustment is completed, the pull plate 507 can be released. The connecting shaft 502 will drive the pin block 508 to insert into the pin slot 509 at the current angle position under the reset force of the spring 506 to limit the connecting shaft 502 and fix the angle of the handlebar 4 on the connecting plate 3, thus completing the adjustment of the angle of the handlebar 4. Through this mechanism, it is convenient for personnel to adjust the angle of the handlebar 4, improve the comfort of different cyclists during cycling, reduce the fatigue, solve the problem that the angle of the existing bicycle handlebar 4 does not have the function of adjustment, resulting in different comfort levels for cyclists with different heights and arm lengths during use, thus increasing the fatigue of cyclists and having low practicability.

[0031] Further, the shapes of both the connecting shaft 502 and the shaft slot 503 are rectangular, and the connecting shaft 502 is adapted to the shaft slot 503; the limiting rod 504 is adapted to the rod slot 505.

[0032] Among them, by setting the connecting shaft 502 and the shaft slot 503 to be rectangular, the connecting shaft 502 can drive the rotating shaft 501 to rotate through the shaft slot 503.

[0033] Further, the number of pin blocks 508 on the inner side of the pull plate 507 is two, the number of pin slots 509 is several, and the pin blocks 508 are adapted to the pin slots 509.

[0034] Among them, by setting the pin blocks 508, the pin blocks 508 can be inserted into the pin slots 509, so as to limit the connecting shaft 502.

[0035] Further, a first magnetic ring 7 is fixedly installed inside the telescopic frame 2, and second magnetic rings 8 are fixedly installed on both sides of the connecting plate 3. The first magnetic ring 7 is magnetically connected to the second magnetic rings 8.

[0036] Among them, by setting the first magnetic ring 7 and the second magnetic rings 8, the stability of the telescopic frame 2 during rotation can be improved, and it is avoided that the telescopic frame 2 can rotate easily.

[0037] Embodiment 2:

[0038] On the basis of Embodiment 1, the preferred embodiment of the adjustable handlebar joint of the bicycle provided by the present invention is as follows Figures 1 to 7As shown in the figure: A telescopic mechanism 6 is provided between the telescopic frame 2 and the frame branch pipe 1. The telescopic mechanism 6 includes a screw rod 604 and a threaded cylinder 601. A cylinder groove 602 is opened at the bottom end of the telescopic frame 2, and a rotating groove 607 is opened at the top end of the inner wall of the cylinder groove 602. The threaded cylinder 601 is inserted into the cylinder groove 602, and the outer wall of the threaded cylinder 601 is rotationally connected to the inner wall of the cylinder groove 602 through a second bearing. A rotating plate 603 is fixedly installed at the top end of the threaded cylinder 601, and the rotating plate 603 is arranged in the rotating groove 607. A screw rod 604 is fixedly installed at the bottom end of the inner wall of the frame branch pipe 1, and the threaded cylinder 601 is threadedly sleeved on the outer wall of the screw rod 604.

[0039] Specifically, in the above technical solution, when the rotating plate 603 is rotated, the rotating plate 603 drives the threaded cylinder 601 to rotate. When the threaded cylinder 601 rotates, it drives the telescopic frame 2 to move upward under the action of the screw rod 604. The telescopic frame 2 then drives the height of the handlebar 4 on the connecting plate 3 to increase. When the rotating plate 603 is rotated in the reverse direction, the height of the handlebar 4 on the connecting plate 3 can be driven to decrease. Through this mechanism, it is convenient for personnel to adjust the height of the handlebar 4, so as to facilitate the use of cyclists of different heights, reduce the usage limitations of the bicycle, and has a simple structure and strong practicability.

[0040] Further, a limiting slider 605 is fixedly installed on the inner wall of the frame branch pipe 1, and a limiting sliding groove 606 is opened on the outer wall of the telescopic frame 2. The limiting slider 605 is slidably connected to the limiting sliding groove 606;

[0041] Among them, by setting the limiting slider 605 and the limiting sliding groove 606, the telescopic frame 2 can be limited, and the stability of the telescopic frame 2 during telescoping can be improved.

[0042] The embodiments of the present invention are given for the purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better explain the principles of the present invention and its practical applications, and to enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.
