However, those with ordinary knowledge in the field of creation should be able to understand that these detailed descriptions and specific embodiments listed in the implementation of this creation are only used to illustrate the creation and are not intended to limit the scope of patent applications for this creation.

The applicant first explains here that throughout the specification, including the following embodiments and claims in the scope of patent application, the terms related to directionality are based on the directions in the drawings. Secondly, in the following embodiments and drawings, the same element numbers represent the same or similar elements or structural features.

Please refer to FIG. 1 and FIG. 2, the rider standpipe 10 of the first embodiment of the present creation includes a standpipe body 20, a bundle pipe 30, a front fork mount 40, and a shock absorber 50.

The vertical tube body 20 has a tube body 21 and a bundle cover 25. The front end of the tube body 21 has a longitudinally extending sleeve portion 22. The inner peripheral surface of the sleeve portion 22 has an inner flange 23 and four first straight grooves 24. The four first straight grooves 24 are opposite to The center of the sleeve portion 22 is arranged annularly at equal intervals (as shown in FIG. 4). The beam cover 25 is locked to the rear end of the tube body 21 with four screws 26, so that a beam groove 27 for fixing the rider tube 12 is formed between them. The vertical pipe body 20 further has an upper cover 28 which is assembled on the top end of the sleeve portion 22 of the pipe body 21 in a screwed manner.

The bundle tube 30 is sleeved on the top end of the front fork riser 14 and is contracted radially by a screw 35 so that the bundle tube 30 can clamp and fix the top end of the front fork riser 14. A part of the bundle tube 30 passes through the sleeve portion 22 of the tube body 21 from the bottom end of the sleeve portion 22 of the tube body 21, so that the top end of the bundle tube 30 is located in the sleeve portion 22, and the bottom end of the bundle tube 30 is It is exposed outside the sleeve part 22. As shown in Figures 2 and 4, the outer circumferential surface of the beam tube 30 has four second straight grooves 31, and the four second straight grooves 31 of the beam tube 30 correspond to the vertical tube body 20 in a one-to-one manner. The four first straight grooves 24 of the sleeve portion 22 are embedded between the four first straight grooves 24 and the four second straight grooves 31 in a one-to-one manner by the four rotation limiting members 32 , So that the vertical tube body 20 and the bundle tube 30 cannot rotate relatively. In addition, as shown in FIGS. 2 and 4, the bundle tube 30 is further equipped with a bushing 33 to reduce surface wear. The bushing 33 has four pockets 34, and each pocket 34 contains a rotation limiting member 32. In order to avoid interference between the bushing 33 and the rotation limiter 32 during assembly. However, it should be supplemented that the number of the rotation limiting member 32, the first straight groove 24, the second straight groove 31, and the receiving groove 34 can be adjusted according to actual needs, and at least one can achieve the rotation limiting effect.

The front fork fixing seat 40 is disposed in the sleeve portion 22 of the tube body 21 and is assembled on the top end of the beam tube 30 in a screwed manner. The front fork fixing seat 40 has an outer flange 41. The outer flange 41 of the front fork fixing seat 40 and the inner flange 23 of the sleeve portion 22 are clamped to each other, as shown in FIG. 3, to prevent the sleeve portion 22 from being pulled out upward. Out. In addition, a ring-shaped cushion 42 is provided between the inner flange 23 and the outer flange 41, and the cushion 42 provides a cushioning effect. As shown in FIG. 3, the front fork holder 40 has a bottom wall 43 and a counterbore 44 penetrating through the bottom wall 43. The counterbore 44 is provided with a compression screw 45 passing through the bundle tube 30. The pattern (not shown in the figure) is assembled by the tightening screw 45, and then the front fork riser 14 is tightened and fixed through the pattern.

The damping body 50 may be a rubber material (such as rubber or plastic), a compression spring or a gas spring, and the rubber material is taken as an example here. The shock-absorbing body 50 is arranged in the sleeve portion 22 of the tube body 21. As shown in FIGS. 2 and 3, the top end of the shock-absorbing body 50 abuts on the bottom surface of the upper cover 28, and the bottom end of the shock-absorbing body 50 abuts on the front The top surface of the bottom wall 43 of the fork holder 40.

It can be seen from the above that when driving on a bumpy road, the impact force received by the front wheels will be transmitted from the front fork riser 14 through the driver riser 10 of this creation to the driver tube 12, and then from the driver tube 12 to the left and right handles. In this process, through the combination of the rotation limiter 32, the first straight groove 24, and the second straight groove 31, the vibration direction of the vertical pipe body 20 can be consistent with the up and down direction of the road surface. The rotation condition occurs, and then the shock absorption body 50 and the cushion pad 42 are combined to provide a cushioning effect to improve driving comfort. In addition, the driver standpipe 10 of the present invention has fewer components than the prior art, and the overall height will not increase, and it can also be used with a general-spec front fork standpipe to increase the convenience of use.

Please refer to Figures 5 to 7, the second embodiment of the creation of the driver's riser 60 is similar in structure to the first embodiment described above, the main difference lies in the additional anti-twist structure and the configuration of the front fork tensioner 70, in detail Of:

The sleeve portion 22 of the tube body 21 has two upper shaft holes 29 that open downwards, and the beam tube 30 has two lower shaft holes 36 that open upwards. The upper shaft hole 29 and the lower shaft hole 36 are opposite each other. An anti-rotation shaft 62 is interposed therebetween. In addition, a shaft sleeve 64 can be further embedded in each lower shaft hole 36, and the sleeve 64 is sleeved on the bottom end of the anti-torsion shaft member 62, so that the configuration of the anti-torsion shaft member 62 and the shaft sleeve 64 can improve the torsional strength .

The front fork tightener 70 has a tightening screw 71, an upper cone nut 74, a lower cone nut 75 and a tightening ring 76. A head 72 of the compression screw 71 is received in the counterbore 44 of the front fork fixing seat 40, and a threaded portion 73 of the compression screw 71 is located in the tube 30; an upper cone nut 74 and a lower cone nut 75 is screwed on the threaded part 73 of the compression screw 71 in a symmetrical manner; the top end of the compression ring 76 has an upper cone hole 77, and the bottom end of the compression ring 76 has a lower cone hole 78. The compression ring 76 uses The upper cone hole 77 and the lower cone hole 78 are sleeved on the upper cone nut 74 and the lower cone nut 75, respectively. Thereby, when the head 72 of the tightening screw 71 is rotated, the upper taper nut 74 and the lower taper nut 75 will be driven by the thread portion 73 of the tightening screw 71 at the same time to approach each other. When the nut 74 and the lower tapered nut 75 approach each other, they simultaneously squeeze the upper tapered hole 77 and the lower tapered hole 78 of the tightening ring 76, so that the tightening ring 76 is radially expanded and the front fork riser 14 It is tightly fixed to the bundle tube 30.
