[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] The utility model provides a technical solution: Figure 1 、 Figure 2 and Figure 3 As shown, in this embodiment, a supported bicycle stem includes a stem body 2 3, a clamping assembly 5 is installed on the outside of the stem body 2 3, a rotating shaft is provided on the inner walls at both ends of the stem body 2 3, and a stem body 1 is provided on the two rotating shafts, and two adjustment assemblies 6 are installed between the stem body 1 and the stem body 2 3, the clamping assembly 5 includes a mounting groove 502 on the top of the outer wall of one side of the stem body 2 3, two springs 505 are fixedly connected to the outer wall of one side of the mounting groove 502 and are horizontally arranged, one end of the two springs 505 is fixedly connected to the same hinge seat 504, the hinge seat 504 is just slidably inserted into the mounting groove 502, and a horizontally arranged groove is provided inside the hinge seat 504.

[0026] A connecting block 503 is hingedly connected inside the hinge seat 504 , and a cover plate 501 is fixedly connected to one end of the connecting block 503 . The cover plate 501 can form a complete circular tube hole with the stem body 2 3 .

[0027] At this time, the cover plate 501 will also clamp the handlebar so that it will not move at will. At the same time, since the connecting block 503 enters the mounting groove 502, the connecting block 503 can no longer be flipped, ensuring that the cover plate 501 will not lose the restriction on the handlebar due to flipping due to external force.

[0028] like Figure 1 and Figure 4 As shown, the adjustment component 6 includes a worm gear 601 coaxially fixed at one end of the rotating shaft of the stem body 2 3, and a mounting seat 602 is fixedly connected to the outer wall of one end of the stem body 1. A vertically arranged worm 603 is rotatably connected to the inside of the mounting seat 602 through a bearing. The worm 603 is engaged with the worm wheel 601, and the worm 603 is driven to rotate inside the mounting seat 602 through the knob. The mounting seat 602 drives the worm wheel 601 to rotate through the engagement, and the worm wheel 601 drives the rotating shaft of the stem body 2 3 to flip synchronously, and then the position of the handlebar fixed inside the stem body 2 3 will also change. Due to the special structure of the worm wheel 601 and the worm 603, it is ensured that the worm wheel 601 will not rotate at will.

[0029] A sprocket 604 is coaxially fixed to one end of the bottom of each of the two worm gears 603 , and the two sprockets 604 are sleeved with the same chain 605 .

[0030] As the worm 603 rotates, the sprocket 604 connected to its shaft end will also rotate synchronously. The sprocket 604 can drive the other sprocket 604 to rotate through the chain 605, and then the other worm wheel 601 will rotate synchronously, so that the operation of the adjustment component 6 can proceed smoothly. With the abutment of the two worms 603, the stability of the handle body 2 3 will also be stronger.

[0031] like Figure 1 and Figure 2 As shown, the circumferential inner walls of the stem body 2 3 and the tube hole of the cover plate 501 are provided with a plurality of equally spaced anti-skid grooves 2, and the circumferential inner wall of the tube hole of the stem body 1 is also provided with a plurality of equally spaced anti-skid grooves 2, which can increase the friction between the stem body 2 3 and the handlebar, thereby effectively preventing the handlebar position from changing arbitrarily.

[0032] like Figure 1 and Figure 2 As shown, two clamping screws 4 are slidably inserted into the outer wall of one end of the stem body 1 and the outer wall of one side of the cover plate 501, and the four clamping screws 4 can be threadedly connected to the inside of the stem body 2 3 and the other end of the stem body 1 respectively, so that the stem body 1 can be tightly clamped on the outside of the head bowl, and the stem body 2 3 can also tightly clamp the handlebar.

[0033] like Figure 1 and Figure 2 As shown, the stem body 1, the stem body 2 3 and the cover plate 501 are all made of alloy steel. The strength, wear resistance and corrosion resistance of this material are relatively high, and it is suitable for use under high loads and harsh environments. In addition, it has good rigidity and can provide good controllability.

[0034] The utility model provides a support type bicycle handlebar, the specific working principle of which is as follows:

[0035] At the same time, since the connecting block 503 enters the mounting groove 502, the connecting block 503 cannot be flipped over, ensuring that the cover 501 does not lose its restriction on the handlebar due to external force. At this time, the clamping screw 4 is screwed into the stem body. The installation can be completed between 2 and 3, and then the angle of the stem body 23 is adjusted according to the user's height to make the handlebar reach a comfortable position. The worm 603 is driven by the knob to rotate inside the mounting seat 602, and the mounting seat 602 drives the worm wheel 601 to rotate through engagement, and the worm wheel 601 drives the rotating shaft of the stem body 23 to flip synchronously, and then the position of the handlebar fixed inside the stem body 23 will also change. Due to the special structure of the worm wheel 601 and the worm 603, the worm wheel 601 is guaranteed not to rotate at will. While the worm 603 rotates, the sprocket 604 connected to its rotating shaft end will also rotate synchronously. The sprocket 604 can drive another sprocket 604 to rotate through the chain 605, and then the other worm wheel 601 will rotate synchronously, so that the operation of the adjustment component 6 can be carried out smoothly. Under the abutment of the two worm gears 603, the stability of the stem body 23 will also be stronger.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
