Embodiment 1

[0030] see Figure 1-6 , a bicycle structure with a hook-type front fork and a stem that can be quickly disassembled, including a stem 1, a frame head tube and a headset 2 at the lower part of the stem 1, and a connection between the stem 1 and the frame head tube and headset 2 A spacer 11 is provided between them, a front fork 3 is provided at the lower end of the stem 1, a stud 6 is arranged at the upper part of the stem 1, and the stud 6 is threadedly connected with a nut 5, and the upper part of the front fork 3 is provided with a front fork standpipe pin 3-1, the front fork standpipe pin shaft 3-1 is clipped to the card slot 1-1 at the bottom of the stem 1 to ensure the synchronous rotation of the stem 1 and the front fork 3, and the upper part of the stem 1 is provided with a handlebar The pin hole 1-4, the handlebar pin hole 1-4 runs through the connecting pin 7, the middle part of the stud 6 is provided with a stud hole 6-1, the stud hole 6-1 is connected with the hand...

Embodiment 2

[0032] see Figure 7-8 , the other content of this embodiment is the same as that of Embodiment 1, the difference is that: the lower part of the nut 5 is provided with a relief groove 5-1, and the inner diameter of the relief groove 5-1 is greater than the length of the button 12. At this time, the button 12 and Not in contact with the relief groove 5-1 at the bottom of the nut 5, the right side of the guide groove 10-3 is provided with a limiting boss 8-5, and the lower part of the hook 8 is provided with a guide slope 8-4. During use, under the action of the spring 9 and the stopper boss 8-5 of the hook 8, the hook 8 is in the state of hooking the pin shaft 3-1 of the front fork standpipe, and when the hook 8 moves downward, the guide slope 8-4 and the When the front fork standpipe pin 3-1 contacts, the hook 8 rotates, and finally under the action of the spring 9, the lower end of the hook 8 is engaged with the front fork standpipe pin 3-1, which is different from the touch ...

Embodiment 3

[0034] see Figure 9-10, the other content of this embodiment is the same as that of Embodiment 1, the difference is that: the left side of the upper part of the hook 8 is provided with a button slot 8-2, the button slot 8-2 is engaged with the button 12, and the nut 5 A retaining ring 13 is provided between the spacer 11, and the middle part of the retaining ring 13 is provided with a fixing hole 13-1, and the fixing hole 13-1 is connected to the threaded hole 5-2 provided at the lower end of the nut 5 by bolts. This working method is free locking. On the basis of the second embodiment, the position of the button 12 on the hook 8 is moved to the left side, and the through hole 1-3 of the stem 1 is also moved to the left side accordingly. When the nut 5 When moving downwards, the button 12 is placed in the step-off groove 5-1, at this time, under the action of the spring 9, the hook 8 is engaged with the pin shaft 3-1 of the front fork riser, at this time, the stem 1 and the f...

Abstract

The invention relates to a handlebar, and discloses a hook-type front fork and handlebar fast disassembly bicycle structure comprising a handlebar stand, the lower part of which is provided with a frame head tube and a headset. The lower end of the handlebar stand is provided with a front fork, and the upper part of the handlebar stand is provided with a bolt, which is in a threaded connection with a nut. The upper part of the front fork is provided with a front fork head tube vertical tube pin shaft, which is connected with a clamping slot disposed in the bottom part of the handlebar stand ina clamped manner. The upper part of the handlebar stand is provided with a handlebar pin shaft hole, which penetrates a connection pin shaft. The pin shaft is rotatably connected with a hook throughhole in the upper end of the hook, and the upper part of the hook is provided with a button. The lower part of the hook is slidably connected with a guiding slot disposed in the middle part of a maintaining rack, and the left side of the maintaining rack is provided with a maintaining rack side hole. The technical scheme provided by the invention is suitable for the hook-type front fork and handlebar fast disassembly bicycle structure, and by arranging the hook, the handlebar is connected with the front fork, the whole connection is firm, and the clamping is prevented from being loosened, andtherefore the radial jump is eliminated. The whole device has advantages of simple operation, convenient disassembly, and applicability in popularization and application.

Description

technical field [0001] The invention relates to a handlebar, in particular to a bicycle structure in which a hook-type front fork and a stem can be quickly disassembled. Background technique [0002] The traditional bicycle front fork is connected to the frame through threaded compression bearing headsets, and the handlebar is fixed to the front fork through screw ramps or screw compression. Special tools are required for disassembly and assembly, which not only increases manpower and material costs, but also brings inconvenience to assembly. . The current market environment pursues devices with low cost, simple structure, and convenient operation. It is necessary to ensure not only the convenience of disassembly and assembly, but also the functional reliability after assembly. [0003] In order to solve the above technical problems, it is necessary to design a device that can quickly realize the quick separation of the front fork, the stem and the vehicle frame only by han...
