The specific embodiment

Conjunction with figs. is enumerated following preferred embodiment, in order to structure of the present utility model and effect are elaborated.

Please consult Fig. 1 and Fig. 2 earlier, be the quick-disassembly structure 10 of the utility model one preferred embodiment, quick-disassembly structure 10 includes a slipper 20, an axle 30, leader 40 and a linked component 50.

Slipper 20 is cylindrical, and has a fluting 22, and fluting 22 rear ends by slipper 20 preset distance that extends internally makes slipper 20 form the sidepiece 26 that a base portion 24 and two is connected base portion 24 respectively.Base portion 24 has the perforation 242 of two sides, perforation front and back, and fluting 22 and perforation 242 are interconnected; Two sidepieces 26 are corresponding mutually, and have a perforation 252 respectively, and each is bored a hole and 252 also is interconnected with fluting 22.

Axle 30 has a head 32, an axial region 34 and two

elastic component

36a, 36b, and head 32 has an axis hole 322; The front end of axial region 34 connects head 32, and perforation 242 is passed by fluting 22 and protruding in the rear end, and the rear end has a thread segment 342, in order to the swivel nut 38 that is spirally connected.Since the external diameter of perforation 242 greater than the external diameter of axial region 34, make axial region 34 relatively slipper 20 move forward and backward; Elastic component 36a then is sheathed on axial region 34, and replaces perforation 242 peripheries of head 32 and base portion 24 respectively, and elastic component 36b is sheathed on axial region 34, and contact swivel nut 38.When axle 30 was mobile forward, elastic component 36a can be subjected to the compressing of head 32 and compressive deformation, and when swivel nut 38 screws, can oppress elastic component 36b.

Handle 40 has a grip part 42, uses for the user to grip.The medial surface of grip part 42 has a storage tank 422, and as shown in Figure 3, and an end of grip part 42 extends two corresponding ears 44, and each ear 44 has one first pivoted hole 441 and one second pivoted hole 443.Two ears 44 of handle 40 are installed in the fluting 22 of slipper 20, and utilize two locationss 46 to pass the perforation 252 and first pivoted hole 441 of slipper 20 in regular turn respectively, make handle 40 slipper 20 pivots relatively.

Linked component 50 includes two double-action plates, 52,54, one first attaching partss 56 and one second attaching parts 58.Each double-

action plate

52,54 is installed in the fluting 22, and between the ear 44 of the head 32 of axle 30 and handle 40, each double-

action plate

52,54 has one first connecting bore 522,542 and one second connecting bore 524,544.First attaching parts 56 passes wherein first connecting bore 522, the axis hole 322 of head 32 and first connecting bore 542 of another double-action plate 54 of a double-action plate 52 in regular turn.58 of second attaching partss pass second pivoted hole 443 of an ear 44 wherein, second connecting bore 544 of second pivoted hole 443 and another double-action plate 54 of second connecting bore 524, another ear 44 of a double-action plate 52 wherein in regular turn.

Via said structure, when upwards pull the grip part 42 that the user holds handle 40, as shown in Figure 4, handle 40 can be that the axle center upwards pivots with two locationss 46, and at this moment, two ears 44 of handle 40 can drive two double-

action plates

52,54 by the effect of second attaching parts 58 and upwards pivot, when two double-

action plates

52,54 upwards pivot, can promote the head 32 of axle 30 by the effect of first attaching parts 56, axle 30 is moved forward, the elastic component 36a of this moment will be oppressed by head 32 and be out of shape.When the downward pulling handle 40 of the application of force, as shown in Figure 3, two ears 44 of handle 40 effect by second attaching parts 58 again drive two double-

action plates

52,54 and pivot downwards, when two double-

action plates

52,54 pivot downwards, spur the head 32 of axle 30 by the effect of first attaching parts 56, make axle 30 move and get back to backward original position, then reinstatement of elastic component 36a at this moment.

See also Fig. 5, be installed in the aspect of the flower-drum 60 of bicycle front-wheel for the utility model.During installing, at first flower-drum 60 is sticked between two

front forks

62,64 of bicycle, then axle 30 is passed flower-drum 60, the thread segment 342 that again swivel nut 38 is screwed in axle 30 is also screwed, make swivel nut 38 be tight against the front fork 64 of bicycle, and compression elastic piece 36b, downward more at last pulling handle 40.Because swivel nut 38 is fixed in axle 32 and is tight against the front fork 64 of bicycle, make axle 32 be fixed and can not move, when handle 40 pivots downwards, two ears 44 of handle 40 drive slipper 20 by two locationss 46 and advance, make the base portion 22 of slipper 20 be tight against the front fork 62 of bicycle, between two

front forks

62,64 that flower-drum 60 and the front-wheel that is connected flower-drum 60 are fixed on bicycle.In the time front-wheel will being disassembled, pulling handle 40 makes progress, as shown in Figure 6, the elastic component 36a of this moment can utilize the base portion 22 of the elastic force pushing and pressing slipper 20 of itself, make base portion 22 still prop up the front fork 62 of bicycle, allow flower-drum 60 and the front-wheel can be suddenly from two front forks 62, fall down between 64, then pull handle 40 backward again, as shown in Figure 7, make handle 40 drive slipper 20 and move backward, slipper 20 will and the front fork 62 of bicycle between produce a gap, and compression elastic piece 36a, thus, can be with flower-drum 60 and two front forks 62 of front-wheel from bicycle, disassemble between 64.

Thus, as long as the utility model is by pulling handle up or down, can be installed in two front forks of bicycle or disassemble using bicycle drive shaft of the present utility model and bicycle front-wheel from two front forks of bicycle, quite convenient and quick in the use, to reach the purpose that increases ease of use.
