In this way, when the retaining member (ie, the connecting member 5) is installed inside the hollow tube body (ie, the vertical tube 1), the outer tooth portion 52 is hooked on the tube of the vertical tube 1 as if it were inverted. a wall to prevent the retaining piece (ie, the joint 5) from coming out of the standpipe 1.

Please refer to FIG. 3 to FIG. 5 . FIG. 5 is a schematic exploded view of the pressing mechanism 1000 according to the embodiment of the present invention. As shown in FIGS. 3 to 5, the pressing mechanism 1000 further includes a pressing ring member 7, and the pressing ring member 7 is sleeved on the standpipe 1. In this embodiment, the tension ring member 7 can be substantially a truncated conical structure, and the groove wall profile of the sleeve groove 20 of the base 2 substantially corresponds to the contour of the truncated conical structure. When the rod portion 61 of the second screw member 6 is screwed to the second screw hole 50 of the coupling member 5, the head portion 60 of the second screw member 6 can press down the top groove wall 202 of the sleeve groove 20. As a result, the pressing ring member 7 can be forced into the socket groove 20. And because the pressing ring member 7 is substantially a truncated conical structure and the groove wall contour of the socket groove 20 substantially corresponds to the structural design of the contour of the truncated conical structure, the pressing ring member 7 is forced into the body. During the process in the socket 20, the pressing ring member 7 can be more tightly clamped to the groove wall of the socket groove 20.

It is worth mentioning that a clamping groove 70 can be formed on the pressing ring member 7. During the forced pressing of the ring member 7 into the socket groove 20, the pressing ring member 7 is pressed to gradually reduce the groove 70, so that the structure of the groove 70 on the tension ring member 7 of the present invention is constructed. The design helps to force the ring member 7 into the socket groove 20, so that the ring member 7 can be more tightly clamped to the groove wall of the socket groove 20.

As shown in FIG. 3 to FIG. 5, the top end portion 10 of the standpipe 1 is formed with a first engaging structure 102, and the base 2 further has a second engaging structure 205 disposed in the socket groove 20. In this way, when the socket groove 20 is sleeved on the top end portion 10, the first engaging structure 102 is engaged with the second engaging structure 205 to prevent the base 2 from being along the central axis of the vertical tube 1 with respect to the vertical tube 1 Rotate. In this embodiment, the first engaging structure 102 can be a card slot, and the second engaging structure 205 can be a snap protrusion. However, the present invention is not limited thereto. For example, the first engaging structure 102 can also be a The engaging protrusions 205 can also be a card slot, depending on actual needs.

Please refer to FIG. 5 to FIG. 7 . FIG. 6 is a schematic cross-sectional view showing the assembly state of the pressing mechanism 1000 in the first state according to an embodiment of the present invention, and FIG. 7 is an assembly cross-section of the pressing mechanism 1000 in the second state according to the embodiment of the present invention. schematic diagram. As shown in FIGS. 5 to 7 , when the pressing mechanism 1000 is assembled, the coupling member 5 is first passed through the opening 101 of the top end portion 10 of the standpipe 1 so that the coupling member 5 is attached to the inside of the standpipe 1 and then The pressing ring member 7 is sleeved on the top end portion 10 of the vertical pipe 1, and then the base 2 is mounted on the vertical pipe 1 so that the pressing ring member 7 sleeved on the top end portion 10 is pre-locked into the socket of the base 2 The groove 20 is formed such that the tip end portion 10 of the standpipe 1 is exposed to the abutment opening 203. At this time, the second engaging structure 205 of the base 2 is engaged with the first engaging structure 102 of the top end portion 10 (as shown in FIG. 6) to prevent the base 2 from standing along the standpipe 1 with respect to the standpipe 1 The center axis rotates.

Next, the rod portion 61 of the second screw member 6 is locked to the second screw hole 50 of the coupling member 5 via the through hole 204 of the top groove wall 202 (as shown in FIG. 7), at the stem portion of the second screw member 6. During the locking of the second screw hole 50, the head 60 of the second screw member 6 presses the top groove wall 202 to force the base 2 to approach the standpipe 1, so that the ring member 7 can be further tightened. The sleeve groove 20 is pushed into the base 2 to prevent the base 2 from shaking relative to the standpipe 1.

As shown in Fig. 7, the pressing block 3 is placed in the chute 21 such that the abutting end wall 30 of the pressing block 3 abuts against the top end portion 10 of the standpipe 1 and the second wedge of the block 3 is forced. The inclined wall 31 fits and abuts against the first wedge-shaped inclined wall 22 of the socket groove 20. Finally, the first screw element 4 is screwed to the first screw hole 23 of the base 2 through the retaining hole 32 on the pressing block 3, and the first screw element 4 is screwed into the first screw hole 23 The first screw element 4 presses the pressing block 3 downward. When the pressing block 3 is pressed down by the first screw member 4, the second wedge-shaped inclined wall 31 of the pressing block 3 slides relative to the first wedge-shaped inclined wall 22 of the socket groove 20, so that the pressing block 3 faces the standpipe 1 mobile. As a result, during the movement of the pressing block 3 toward the standpipe 1, the abutting end wall 30 of the pressing block 3 can press the top end portion 110 of the standpipe 1. Compared with the prior art, the present invention provides a pressing mechanism and a related two-wheel carrier using a wedge-shaped inclined wall as a pressing mechanism. When the first screw component is screwed to the first screw hole, the pressing block can be first. The screw member is depressed to slide the second wedge-shaped inclined wall relative to the first wedge-shaped inclined wall, so that the pressing block moves in the chute toward the vertical pipe. In this way, the pressing block of the present invention can press the top end portion of the standpipe, and the first screw member and the pressing block of the present invention are both disposed inside the base, that is, the present invention can utilize the wedge-shaped inclined wall as the pressing force. The mechanism of the tensioning mechanism, the invention further integrates the above structure and components into the base, which helps to improve the overall appearance of the two-wheeled vehicle. The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
