Abstract
The utility model discloses a bicycle quick dismounting device, aiming to overcome the inconveniency in quick disassembly of fastening component of the bicycle. The utility model comprises a wrench, a quick dismounting screw, a setting nut and a support cluster under the seat; wherein, the top of the wrench is provided with two opposite lugs; a slot is formed between the two lugs, and the two lugs are provided with corresponding eccentric orifices; one end of the quick release screw is provided with a through hole and is arranged in the slot; a pin goes through the eccentric orifices and the through hole; the setting nut is arranged at the other end of the quick release screw and is in a shape of hexagon; one end of the support cluster has a groove, and the setting nut can be rightly placed in the groove so as to prevent the setting nut from revolving. When the utility model is in locking, loosen the wrench and revolve so as to drive the quick release screw to rotate, and the setting nut is tucked in the quick release screw, and then trip the wrench to lock. The utility model is convenient in operation, easy in manufacture and low in cost; during the locking, the utility model can fulfill the fixation without any help of extra tool.
Description
Affiliated technical field
The utility model relates to a kind of bicycle quick-detaching device.
Background technology
As shown in Figure 1, be a kind of bicycle quick-detaching device of commonly using, this device for quickly disassembling comprises a spanner 6, a quick detach screw 1 and a setscrew nut 2.These spanner 6 tops are provided with 5 short slots that form a depression of two cooresponding lug 5, two lugs of curved arc, respectively wear a cooresponding eccentric orfice 4 on two lugs, the 5 ear faces.Quick detach screw 1 one ends are provided with perforation, quick detach screw 1 one ends place short slot, one pin 8 wore the perforation of two eccentric orfices 4 and quick detach screw 1 one ends simultaneously, spanner 6 can freely be pulled, be provided with the washer cover that washer that a plastic material makes and iron sheet are made again, washer, washer cover are arranged on the quick detach screw 1 successively, and washer is near being formed with the curved arc face that rotates for lug 5 on the one side of two lugs 5.Quick detach screw 1 other end forms thread end, and setscrew nut 2 coupling ground spiral shells are on the thread end of quick detach screw 1.During use, quick detach screw 1 wore two holes of restrainting son 3 under the seat, and setscrew nut 2 spiral shells are on the thread end of quick detach screw 1, and when initial locking, tool constantly screws setscrew nut 2 by hand, and this like this quick detach is very inconvenient when adjustment is fastening.
Summary of the invention
The deficiency of inconvenient operation when existing adjustment fastening in order to overcome existing bicycle quick-detaching.The utility model provides a kind of new bicycle device for quickly disassembling for this reason, and this device for quickly disassembling is not adjusted fastening time operation easily, need not use various hand tools.
The utility model for the technical scheme that solves its technical matters and adopt is: this new bicycle device for quickly disassembling, comprise a spanner, a quick detach screw, setscrew nut and seat bundle down are young, this spanner top is provided with two cooresponding lugs, form a short slot between two lugs, two lugs are provided with cooresponding eccentric orfice, quick detach screw one end is provided with perforation and places short slot, one pin wore eccentric orfice and perforation simultaneously, the setscrew nut spiral shell is in the other end of quick detach screw, setscrew nut is hexagon, the seat young end of bundle down is provided with groove, and setscrew nut just can place groove, and setscrew nut can not rotated.
Setscrew nut is made with nylon.
The specification of quick detach screw and setscrew nut is 0.7 millimeter of thread * pitch of M6.
The beneficial effects of the utility model are: since seat down the young end of bundle be provided with groove, setscrew nut just can be placed in one, make its not can with the transfer of quick detach screw; When locking like this, loosen spanner, the rotation by spanner drives the quick detach screw with this and rotates, and setscrew nut is constantly entered in the quick detach screw, pull spanner locking at last and get final product.Find out that therefrom the utility model is easy to operate, need not use external instrument in the locking process, and simple, the whole product of manufacturing process is originally lower.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of commonly using device for quickly disassembling;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Embodiment: referring to Fig. 1 and Fig. 2, a kind of new bicycle device for quickly disassembling, comprise a spanner 6, a quick detach screw 1, setscrew nut 2 and seat be bundle young 3 down, these spanner 6 tops are provided with two cooresponding lugs 5,5 of two lugs form a short slot, two lugs 5 are provided with cooresponding eccentric orfice 4, quick detach screw 1 one ends are provided with perforation, quick detach screw 1 one ends place short slot, one pin 8 wore eccentric orfice 4 and perforation simultaneously, and spanner 6 can freely be pulled, and setscrew nut 2 spiral shells are in the other end of quick detach screw 1, setscrew nut 2 is hexagon, seat young 3 one ends of bundle down is provided with groove 7, and setscrew nut 2 just can place groove 7, and setscrew nut 2 can not be rotated, setscrew nut 2 usefulness nylon are made, and the specification of quick detach screw 1 and setscrew nut 2 is 0.7 millimeter of thread * pitch of M6.
During use, setscrew nut 2 places the seat groove 7 of the young 3 one ends setting of bundle down, loosen spanner 6, the rotation by spanner 6 drives quick detach screw 1 with this and rotates, because setscrew nut 2 just places the seat groove 7 of young 3 one ends of bundle down, setscrew nut 2 can not rotated, setscrew nut 2 is constantly entered in the quick detach screw 1, pulls spanner 6 lockings at last and gets final product.Find out that therefrom the utility model is easy to operate, need not use external instrument in the locking process, and simple, the whole product of manufacturing process is originally lower.
In the utility model, seat young 3 one ends of bundle down also can only form at least one gear block, setscrew nut 2 has at least side, a place and gear block side view to be complementary and both are close to, so also can make setscrew nut 2 can transfer not take place, but the manufacturing process complexity, make the higher and inconvenient operation of cost with quick detach screw 1.It equally also is the claimed scope of the utility model.
The used setscrew nut 2 of the utility model is a hexagon again, and also quadrangle only is simply to be equal to replacement, equally also is the claimed scope of the utility model.
