[0035] Example:
[0036] refer to Figures 1-6, a space-saving folding handlebar, comprising: a left handlebar cross tube 1, a right handlebar cross tube 2, a stem mounting block 3 and a tightening and pressing block 4. The left handlebar cross tube 1 and the right handlebar cross tube 2 are respectively mounted on the left and right sides of the stem mounting block 3. The tightening and pressing block 4 is mounted on the stem mounting block 3 and is slidably connected to the stem mounting block 3. An adjusting screw 5 is connected to the stem mounting block 3, one end of the adjusting screw 5 is connected to the tightening and pressing block 4, and the adjusting screw 5 is used to adjust the position of the tightening and pressing block 4 on the stem mounting block 3 so that the tightening and pressing block 4 can tighten or loosen the left handlebar cross tube 1 and the right handlebar cross tube 2. The handlebar mounting block 3 is provided with a left mounting hole 31 and a right mounting hole 32, and the left handlebar cross tube 1 and the right handlebar cross tube 2 are respectively arranged in the left mounting hole 31 and the right mounting hole 32, so that the end faces of one end of the left handlebar cross tube 1 and the right handlebar cross tube 2 are inserted into the left mounting hole 31 and the right mounting hole 32 for preliminary position installation, and the tightening block 4 is provided with a left first clamping half hole 41 and a right first clamping half hole 42. The left first clamping half hole 41 cooperates with the side wall of the left handlebar cross tube 1 to fix the position of the left handlebar cross tube 1 by squeezing, and the right first clamping half hole 42 cooperates with the side wall of the right handlebar cross tube 2 to fix the position of the right handlebar cross tube 2 by squeezing. The adjusting screw 5 can be rotated to force the tightening block 4 to move toward the position of the left handlebar cross tube 1 and the right handlebar cross tube and squeeze the left handlebar cross tube 1 and the right handlebar cross tube, thereby fixing the position of the left handlebar cross tube 1 and the right handlebar cross tube.
[0037] refer to Figure 5 and Figure 6 In order to provide certain support to the other side of the left handlebar cross tube 1 and the right handlebar cross tube 2, thereby more stably fixing the left handlebar cross tube 1 and the right handlebar cross tube 2, a support portion extends upward from the stem mounting block 3, and a left second clamping half hole 331 and a right second clamping half hole 332 are provided on the support portion. The left second clamping half hole 331 fits with one side of the left handlebar cross tube 1 inserted into the left mounting hole 31, and the right second clamping half hole 332 fits with one side of the right handlebar cross tube 2 inserted into the right mounting hole 32, thereby supporting one side of the left handlebar cross tube 1 and the right handlebar cross tube 2 through the left second clamping half hole 331 and the right second clamping half hole 332.
[0038] refer to Figure 5 In order to further fix the positions of the left handlebar cross tube 1 and the right handlebar cross tube 2 on the stem mounting block 3, elastic ball head set screws 6 are installed on the left and right sides of the stem mounting block 3. The elastic ball head set screws 6 are respectively tightened against the corresponding left handlebar cross tube 1 and right handlebar cross tube 2, thereby further fixing the left handlebar cross tube 1 and the right handlebar cross tube 2 on the stem mounting block 3.
[0039] refer to Figure 3-Figure 6In order to further fold the handlebars and reduce the volume and space occupied, it also includes a stem fixing block 7, which is fixedly connected to the head tube of the vehicle. One side of the stem mounting block 3 is hinged to the stem fixing block 7, so that the stem mounting block 3 can be folded to reduce the space occupied when it needs to be stored. A hook 43 extends from one side of the tightening pressure block 4, and a notch 71 is provided on the stem fixing block 7 to cooperate with the hook 43. When the adjusting screw 5 locks the tightening pressure block 4, the hook 43 is engaged with the notch 71, so that the engagement of the hook 43 with the notch 71 ensures that the stem mounting block 3 will not be folded relative to the head tube when the vehicle is in use, thereby not affecting the use of the vehicle.
[0040] refer to Figure 2 , Figure 4-Figure 6 A first protrusion 34 extends from the stem mounting block 3, and a first through hole 341 is formed in the first protrusion 34. A second protrusion 45 extends from the tightening block 4, and a second through hole 451 is formed in the second protrusion 45. The first through hole 341 and the second through hole 451 are coaxial, and a hexagonal nut 51 is installed in the second through hole 451. The rod body of the adjusting screw 5 passes through the first through hole 341 and the second through hole 451 and is threadedly connected to the nut 51 in the second through hole 451, thereby realizing the connection between the stem mounting block 3 and the handlebar tightening block 4 through the adjusting screw 5.
[0041] refer to Figure 3 and Figure 4 When the handlebars need to be folded, the stem fixing block 7 needs to be away from the stem mounting block 3. Therefore, it is necessary to be able to move the stem fixing block 7 away from the stem mounting block 3 when the adjusting screw 5 is loosened. In order to reduce the manual movement of the stem fixing block 7, a spring 52 is provided on the adjusting screw 5. The two ends of the spring 52 respectively rest on the opposite ends of the stem mounting block 3 and the stem fixing block 7. Therefore, when the adjusting screw 5 is loosened, the stem fixing block 7 can be automatically pushed away from the stem mounting block 3 under the action of the elastic force of the spring 52.
[0042] refer to Figure 6 In order to ensure that the stem fixing block 7 does not deviate left or right during the movement on the stem installation, a guide protrusion 35 extends from the stem mounting block 3, and a guide groove 44 is provided on the tightening block 4. The guide groove 44 and the guide protrusion 35 cooperate to guide the sliding of the tightening block 4 on the stem mounting block 3.
[0043] Operation process: When the angles of the left handlebar tube 1 and the right handlebar tube 2 need to be adjusted, loosen the adjustment screw 5 and the elastic ball head set screw 6 to rotate the left handlebar tube 1 and the right handlebar tube 2, thereby adjusting their horizontal angles and the vertical angles.
[0044] When the handlebars need to be further stored to reduce the space occupied, the adjusting screw 5 is further loosened until the hook 43 of the tightening pressure block 4 is disengaged from the notch 71 on the stem fixing block 7, so that the handlebars can be folded, thereby further reducing the space occupied by the handlebars and making it easier to put them into the trunk of the car.
