In the combined structure of the front fork standpipe and the standpipe provided by the utility model, the quick release assembly has a pivot, a handle, and a connecting shaft, and the pivot is pivotably arranged on a pivot of the standpipe. One end of the handle has one or two ears to form a pivot connection with the pivot, and the two ends of the connecting shaft are connected to the standpipe and the pivot respectively.

The following preferred embodiments are listed below in conjunction with the accompanying drawings, in order to describe the structure and effect of the utility model in detail.

Please refer to Fig. 1 and Fig. 2 first, which is the combined structure 10 of the front fork standpipe 12 and the standpipe 14 of the first preferred embodiment of the present invention, including a front fork standpipe 12, a standpipe 14, and a bushing 16. A quick release component 20 , an upper harness 30 , a pressing component 40 , and a lower harness 50 .

One end of the standpipe 14 is used for assembly of a handlebar of a bicycle, and the other end has a hoop 141, and the hoop 141 runs through a socket hole 142 longitudinally, and is used to cover the top of the front fork standpipe 12. The hoop 141 A pivot joint 144 and a mounting portion 146 extend outwards from both ends of the hoop respectively. In addition, as shown in FIG. 3 , a rotation limiting block 148 protrudes downward from the bottom edge of the hoop 141 .

As shown in Figure 3, the bushing 16 is located in the socket hole 142 of the standpipe 14 and is located between the outer tube wall of the front fork standtube 12 and the hole wall of the socket hole 142 of the standpipe 14, in order to avoid the front Wear occurs between the standpipe 12 and the standpipe 14 . The top of the bushing 16 has a retaining edge 162, which is used to block the top surface of the hoop 141 of the standpipe 14, so that the bushing 16 will not fall off from the socket hole 142 of the standpipe 14. In addition, the bushing 16 has A split groove 164 enables the bushing 16 to be radially deformed by an external force.

The quick release assembly 20 has a pivot 21 , a handle 22 , and a connecting shaft 23 . Both ends of the pivot 21 are respectively pivotally mounted on the pivotal portion 144 of the standpipe 14 via a lock piece 26; The two ends of the shaft 21; the connecting shaft 23 has an adjustment sleeve 24 and a shaft rod 25, the adjustment sleeve 24 is screwed on the mounting portion 146 of the standpipe 14, one end of the shaft rod 25 is sleeved on the pivot shaft 21, and the shaft rod The other end of 25 is locked to the adjustment sleeve 24 via a lock piece 26, so that when the handle 22 is pressed, the hoop 141 of the standpipe 14 will contract radially to tighten the standpipe 14 on the The top of the front fork standpipe 12 , the standpipe 14 will be integrated with the front fork standpipe 12 . On the contrary, when the handle 22 is released, the fastening force of the hoop 141 of the standpipe 14 to the outer peripheral surface of the front fork standpipe 12 disappears, and the standpipe 14 can rotate relative to the front fork standtube 12, as shown in FIG. 4 , The standpipe 14 does not drive the front wheel to rotate through the front fork standpipe 12 when rotating and storing, so that the rider can store and transport the car body conveniently, and it can also be used in the folding design of the folding bike.

And when the adjustment sleeve 24 is rotated, the screwing distance between the adjustment sleeve 24 and the mounting portion 146 of the standpipe 14 will be changed, that is, the connection relationship between the adjustment sleeve 24 and the shaft rod 25 will be changed, so as to promote the driving The axial displacement of the shaft 25 can adjust the tightness of the handle 22 during operation. In addition, when the shaft 25 moves, the lock 26 can be locked without separation from the adjustment sleeve 24 .

The upper harness 30 is sleeved on the top of the front fork stem 12 and its bottom edge is pressed against the retaining edge 162 of the bushing 16 , as shown in FIG. 3 .

The pressing assembly 40 in this embodiment has an upper cover 42, a bolt 44, and a spline 46. As shown in the second and third figures, the upper cover 42 is arranged on the top of the front fork riser 12 and abuts on it. The top edge of the bundle member 30 ; the bolt 44 is rotatably passed through the upper cover 42 and extends into the front fork riser 12 ; Thus, when the bolt 44 is turned, in addition to driving the spline 46 to tighten the inner tube wall of the front fork standpipe 12, it will also drive the upper cover 42 downward to tighten the upper beam 30, so that the front fork stands There can be good structural stability between the tube 12 and the standpipe 14 .

The lower beam member 50 is sleeved on the front fork standpipe 12 and is located at the bottom edge of the vertical tube 14. The top edge of the lower beam member 50 has a rotation limiting groove 52, as shown in FIGS. 2 and 3, for the vertical tube 14. The rotation limiting block 148 is embedded to limit the rotation angle of the standpipe 14 . What needs to be added here is that the rotation limiting groove 52 does not have to be formed on the top edge of the lower bundle member 50 , but can also be arranged on the bottom edge of the upper bundle member 30 . The top edge of the hoop 141 protrudes upwards, in other words, as long as one of the upper and lower beam members 30, 50 has a rotation limiting groove 52, the desired effect can be achieved.

It can be seen from the above structure that the combination structure 10 of the present invention utilizes the design of the upper and lower beam parts 30, 50, and the installation of the pressing assembly 40 can indeed increase the structural stability between the front fork stem 12 and the stem 14. Moreover, the position of the lower beam 50 can be adjusted and fixed on the front fork stem 12 according to the different sizes of the stem 14, so as to increase the convenience in use.

On the other hand, the handle of the quick release assembly can have different forms, as shown in Figure 5, the combined structure 60 of the front fork standpipe 61 and standpipe 62 provided for the second preferred embodiment of the present utility model, its main The structure is roughly the same as that of the above-mentioned first embodiment, but the difference is that the handle 64 of the quick release assembly 63 has only a single ear 642 to form a pivot connection with the top of the pivot, so that in addition to achieving the original tightening effect, it can also avoid The problem that the two ear portions 221 of the handle 22 of the above-mentioned first embodiment get stuck during operation.

Please refer to Fig. 6 and Fig. 7 again, for the combined structure 70 of the front fork standpipe 71 and the standpipe 72 provided by the third embodiment of the present utility model, its main structure is roughly the same as that of the second embodiment, but the difference lies in the front fork standpipe 71 and the vertical pipe 72. The structure of the fork standpipe 71 and the pressing assembly 80. In this embodiment, the front fork stem 71 is sleeved with a frame tube 90 , and the top end of the front fork stem 71 has an internal thread 712 , and the bottom end of the front fork stem 71 has a first slope 713 . The pressing assembly 80 has an upper cover 82, a bolt 84, and a pressing block 86, wherein the upper cover 82 has an external thread portion 822, so that the upper cover 82 can be screwed on the front fork standpipe by its own external thread portion 822 71 and fixed on the top of the front fork standpipe 71 to achieve the effect of tightening the upper beam 73; the bolt 84 can be rotatably set in the front fork standpipe 71; the tightening block 86 bolt It is located at the end of the bolt 84 and has a second inclined surface 862 , the second inclined surface 862 of the pressing block 86 is in contact with the first inclined surface 713 of the front fork stem 71 . Thus, when the bolt 84 is turned, the pressing block 86 will move obliquely relative to the front fork riser 71 through the cooperation between the second slope 862 of itself and the first slope 713 of the front fork riser 71, so that The pressing block 86 is pressed against the inner tube wall of the vehicle frame tube 90 by a pressing surface 864 to complete the fixing between the combination structure 70 of the present invention and the vehicle frame tube 90 .

The constituent components disclosed in the above embodiments of the utility model are only for illustration and are not used to limit the scope of the utility model. The substitution or change of other equivalent components should also be within the scope of the claims of the utility model. covered.
