Establish a set collar 72 in the locking part 35 sheathed flywheel sheets 71 of engagement and the spiral shell of described ratchet sleeve 30 at last, make described steady ring 40 can not break away from described ratchet sleeve 30, and the maximum outside diameter D3 of described control loop 60 is the maximum outside diameters greater than described flywheel sheet D4 with described control loop 60.
The above is the structure and the configuration explanation thereof of each primary member of the utility model embodiment.
As for operating mode and the effect thereof of the utility model embodiment, extremely shown in Figure 8 as Fig. 4.
When the utility model carries out the start of the unidirectional output kenel of unidirectional input:
As shown in Figure 4, at first described control loop 60 is pushed towards described shell 20 directions, make of the axial generation displacement of described control loop 60 along described ratchet sleeve 30, simultaneously, described control loop 60 supports the described steady ring 40 of portion's 61 pushing and pressing by its ring, make described steady ring 40 same axial generation displacements along described ratchet sleeve 30, when the latch 611 of described control loop 60 is moved to draw-in groove 341 that should ratchet sleeve 30, consult Fig. 6, Fig. 7,611 of the latches of described control loop 60 no longer fasten mutually with the protuberance 342 of described ratchet carriage 30, and each male part 41 of described steady ring 40 is positioned the location division 211 of described shell 20, and then, consult Fig. 7, Fig. 8, rotate described control loop 60 1 angles, make the latch 611 of described control loop 60 be positioned at the draw-in groove 341 of described ratchet sleeve 30, and fasten mutually, at this moment, because being the location divisions 211 with described shell 20, the male part 41 of described steady ring 40 fastens mutually, and the interior protuberance 42 of described steady ring 40 is that protuberance 342 with described ratchet sleeve 30 fastens mutually, therefore, no matter described shell 20 forwards or backwards rotation, described ratchet sleeve 30 all can be along with rotation, and the flywheel sheet 71 that is engaged in described gear sleeve 30 rotates and rotates along with described shell 20 equally, uses the kenel of reaching the unidirectional output of the unidirectional input of the utility model flower-drum.
When the utility model carries out the start of the unidirectional output kenel of two-way input:
As Fig. 6, shown in Figure 7, at first rotate described control loop 60 1 angles, the latch 611 of described control loop 60 and the draw-in groove 341 of described ratchet sleeve 30 are broken away from mutually, allow the recess 343 that 611 pairs of the latches of described control loop 60 should ratchet sleeve 30 simultaneously, at this moment, consult Fig. 3, Fig. 4, elastic restoring force by elastic element 50, make described steady ring 40 and described control loop 60 produce displacement with direction away from described shell 20, till described control loop 60 is resisted against described flywheel sheet 71,41 location divisions 211 that break away from described shells 20 of the male part of described steady ring 40 of while, therefore, when described shell 20 forwards or backwards rotation, described ratchet sleeve 30 only can produce unidirectional same moving with described shell 20 by its ratchet group 33, uses the kenel of reaching the unidirectional output of the two-way input of the utility model flower-drum.
In sum, via the utility model structure design, allow the user not need instrument can directly control described control loop 60, make the male part 41 of described steady ring 40 and location division 211 location or the disengaging mutually mutually of described shell 20, allow two kinds of kenels of the unidirectional output of unidirectional output of the two-way input of flower-drum of the present utility model conversion at any time and unidirectional input, use and reach the purpose that improves described flower-drum applicability.
As shown in Figure 8, because the utility model is provided with a limited post 344 in each protuberance 342 of described ratchet part 34, and described limited post 344 is placed through the draw-in groove 341 of described ratchet part 34, therefore, when the latch 611 of described control loop 60 is moved to draw-in groove 341 that should ratchet sleeve 30 and rotates, described limited post 344 is limited the latch 611 of described control loop 60 in the angle that described draw-in groove 341 rotates, and promotes the accuracy that described latch 611 and described draw-in groove 341 fasten mutually.
As shown in Figure 4, the utility model is designed to maximum outside diameter D4 greater than described flywheel sheet 71 with the maximum outside diameter D3 of described control loop 60, and because described flywheel sheet 71 mainly is and cycle chain (figure does not show) makes up, therefore, the utility model is when controlling described control loop 60, can not touch described flywheel sheet 71 and chain thereof, and be kept clean.
As shown in Figure 9, when the utility model flower-drum is the kenel of the unidirectional output of two-way input, it mainly is to arrange in pairs or groups with the ratchet ring 22 of described shell 20 by the ratchet group 33 of described ratchet sleeve 30 to form, just when shell 20 rotations, ratchet pawl 331 rotation that centnifugal force can drive described ratchet group 33 open outward with described shell 20 in ratchet ring 22 eat and close, can drive described flower-drum and produce wheel and change; And described ratchet pawl 331 can contract inwardly when shell 20 counter-rotatings, can not produce to eat and close with described ratchet ring 22, shell 20 meetings this moment are dallied voluntarily and can not driven described ratchet ring 22 rotations, use the kenel of reaching the unidirectional output of the two-way input of flower-drum, because this kenel belongs to known technology, so no longer given unnecessary details.
