Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
First embodiment
See Fig. 1-Fig. 3, the colored hub structure of the improvement of the present embodiment, the screw rod 7 comprising colored hub 1 and be inserted in colored hub 1, and the clutch-plate 4 of inclined-plane rotation preventive mechanism on screw rod 7 and rotation is fixed on by nut 6, in flower hub 1, both sides all arrange bearing 2, to improve stability when colored hub 1 rotates and precision.
See Fig. 4-Fig. 6, inclined-plane rotation preventive mechanism comprises inner core 3 and spline part 8.In core 3 surface arrange twice tilt cambered surface 3.1, the track a of two highly gradients is formed between cambered surface 3.1 and the smooth inwall of flower hub 1, spline part 8 is cylinder, and be movablely arranged in track a, the diameter of spline part 8 is less than the gradually high-end height of track a, and is greater than the height of track a gradually short end.
Furtherly: respective protrusions two salient point 4.1 on clutch-plate 4 one side plane, salient point 4.1 is placed in track a gradually between short end and spline part 8, opposite side plane is extended with service portion 4.2, and service portion 4.2 exposes to colored hub 1 one side.
Furtherly: separated by projection 3.2 between two cambered surface 3.1 head and the tail, form the track a that two head and the tail are corresponding, two track a structures are identical; Spline part 8 arranges two, is placed in two track a respectively; What salient point 4.1 was symmetrical arranges two, is placed in respectively in track a.
Furtherly: inner core 3 is bolted on screw rod 7, and with flower hub 1 coaxially arrange.Clutch-plate 4 is rotating to be inserted on screw rod 7, and salient point 4.1 gradually moves back and forth between short end and spline part 8 in track a, can touch to certain position with projection 3.2 or spline part 8.Touching projection 3.2, is used as clutch-plate 4 limited location, and touching spline part 8, flower hub 1 plays unblock effect.
See Fig. 7, in order to improve stability, can increase by a spring 12 between spline part 8 and track a are gradually high-end.
See Fig. 6, in core 3 maintain static, and salient point 4.1 do not act on spline part 8 state under, flower hub 1 freely can rotate along the direction of arrow in figure, if when colored hub 1 is along the counter-rotation of arrow in figure, spline part 8 moves toward the gradually short end of track a, when track a highly starts the diameter being less than spline part 8, spline part 8 clamping can not be moved, and spends hub 1 locked simultaneously, can not rotate, cause flower hub 1 can only unidirectional rotation.Under locking state, effect clutch-plate 4 rotates in the direction of the arrow, salient point 4.1 touches the gradually high-end movement of spline part 8 toward track a, keep the effect of salient point 4.1 pairs of spline parts 8, realize unlocking, now spend hub 1 not only along arrow counter-rotation, can also rotate in the direction of the arrow, realize Double-directional rotary; If no longer External Force Acting clutch-plate 4, flower hub 1 recovers unidirectional rotation.
Second embodiment
See Fig. 8-Figure 10, the colored hub structure of the improvement of the present embodiment, the screw rod 7 comprising colored hub 1 and be inserted in colored hub 1, and the clutch-plate 4 of very heavy rotation preventive mechanism on screw rod 7 and rotation is fixed on by nut 6, in flower hub 1, both sides all arrange bearing 2, to improve stability when colored hub 1 rotates and precision.
Very heavy rotation preventive mechanism comprises clutch block 11 and two pieces of ratchets 9, clutch block 11 weeks sides are symmetrically arranged with the breach for assembly ratchet 9, ratchet 9 is movable, and symmetrical assembly is in breach, the position of the corresponding clutch block 11 of flower hub 1 inwall arranges ratchet bar 1.1, stuck on ratchet bar 1.1 when ratchet 9 opens.
Furtherly: respective protrusions two salient point 4.1 on clutch-plate 4 one side plane, salient point 4.1 is placed in track a gradually between short end and spline part 8, opposite side plane is extended with service portion 4.2, and service portion 4.2 exposes to colored hub 1 one side.What the salient point 4.1 on clutch-plate 4 was symmetrical arranges two, and is placed between clutch block 11 surface and flower hub 1 inwall, and clutch-plate 4 freely rotates.
Furtherly: see Figure 15-Figure 17, clutch block 11 arc surface is provided with circular groove 11.1, and on ratchet 9, correspondence is provided with groove 9.1, is equipped with very heavy spring 10 in circular groove 11.1 and groove 9.1 simultaneously; Be provided with arcwall face 11.1 in breach to match with the arcwall face 9.2 on ratchet 9, what be conducive to ratchet 9 opens activity.
Furtherly: clutch block 11 is fixed on screw rod 7, and with flower hub 1 coaxially arrange.Clutch-plate 4 is rotating to be inserted on screw rod 7, and salient point 4.1 is freely movable between clutch block 11 surface and flower hub 1 inwall, when ratchet 9 opens stuck on ratchet bar 1.1 time, salient point 4.1 touches ratchet 9.
See Figure 12, clutch block 11 maintains static, and salient point 4.1 do not act on ratchet 9 state under, flower hub 1 can rotate along the direction of arrow in Figure 12, but when flower hub 1 moves along arrow reversing sense, because ratchet 9 elasticity under the effect of very heavy spring 10 is opened, so ratchet 9 can be taken advantage of a situation stuck on ratchet bar 1.1, now spend hub 1 can not be rotated by locked, cause flower hub 1 can only unidirectional rotation.See Figure 11, under flower hub 1 locking state, effect clutch-plate 4 rotates along the direction of arrow in Figure 11, salient point 4.1 can touch ratchet 9, and the power overcoming very heavy spring 10 makes ratchet 9 depart from ratchet bar 1.1, keep the effect of salient point 4.1 pairs of ratchets 9, flower hub 1 realizes Double-directional rotary; If no longer External Force Acting clutch-plate 4, flower hub 1 recovers unidirectional rotation.
Above-mentioned is preferred version of the present utility model, shows and describes groundwork of the present utility model, principal character and advantage of the present utility model.Those skilled in the art should understand the utility model and not be restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
