Detailed description of the invention
With embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, a kind of bicycle chain puller provided by this utility model preferred embodiment
Clutch unit 1, is arranged between a chain guide card 2 and a linkage (not shown), clutch unit 1
Including body 10, positioning component 20, pressure-applying unit 30 and the enclosing cover 40 being located on body 10,
So that positioning component 20 and pressure-applying unit 30 are enclosed in the inner space between body 10 and enclosing cover 40.
Body 10 is provided with a storage tank 11 in hollow tube-shape and in the side being relatively distant from chain guide card 2, makes chain
The rotating shaft 2a of guide card 2 can run through body 10 and protrude out the bottom center of storage tank 11.Therefore, body 10
Can mutually rotate is articulated on chain guide card 2.Additionally, follow-up explanation is to highlight the 11 of storage tank with rotating shaft 2a
Projected direction is described as top.
Positioning component 20 has a ratchet 21, and ratchet 21 is articulated in storage tank 11 centered by rotating shaft 2a,
And with rotating shaft 2a synchronous axial system, and the periphery of ratchet 21 is provided with the ring-type some ratchet 21a arranged at equal intervals；
One retainer 22 both sides lock on body 10 and abut against the periphery of ratchet 21；At least one detent
24 (they being four at the present embodiment) can and at least one accommodating hole 23 being arranged on retainer 22 of linear sliding (at this
Embodiment is also four) in the middle of, and one end of the relatively close ratchet of each detent 24 21 be equipped with for and spine
The engaging tooth 24a that the ratchet 21a of wheel 21 is meshed；One stator 25 locks and covers above retainer 22
All accommodating holes 23；And at least one elastic component 26, it is compression spring and quantity is four at the present embodiment,
Respectively with its two ends contact between detent 24 and retainer 22, with to ratchet 21 apply elastic force and then
Detent 24.Additionally, each ratchet 21a is to be collectively formed with a upright stopping surface by an inclined plane, make this
Ratchet 21 is being engaged under the effect on ratchet 21a by detent 24, can only one-directional rotation.It addition,
Need to remark additionally, the quantity of detent 24, accommodating hole 23 and elastic component 26 the most only needs one,
Realize the holding function of bicycle chain puller, be not necessarily to multiple could realize.
As shown in Figure 4, in the present embodiment, the periphery of ratchet 21 is provided with 24 ratchet 21a, the most each ratchet
21a is 15 degree with the angle theta at ratchet 21 center.In order to improve degree of accuracy, detent 24, accommodating hole 23
And the quantity of elastic component 26 then needs to be provided with multiple, the present embodiment is by the engaging tooth of two adjacent detent 24
24a is respectively set to θ 1=θ 2=with the angle theta 1 at ratchet 21 center (i.e. rotating shaft 2a center), θ 2 and θ 3
θ 3=33.75 degree (i.e. 360/24*2+ (360/24)/4, wherein N=2) equiangularly spaced arrangement.Based on location
Ratchet position is set, the rotation precision of positioning component 20 can be promoted to 3.75 degree from original 15 degree,
Namely improve 4 times.
In other words, it is assumed that the end face of ratchet 21 is provided with X ratchet 21a, there is Y detent 24
In the case of (wherein X is the positive integer more than 2, and Y is the positive integer more than or equal to 2), if detent 24
Equiangularly spaced arrangement, the then degree of accuracy that positioning component 20 rotates is used to be only △=360/X degree；If location spine
Pawl 24 uses the equiangularly spaced arrangement of above-mentioned formula, i.e. two adjacent detent 24 and the angles at ratchet 21 center
It is set as that △ degree * N spends plus (△/Y), then the rotation precision of positioning component 20 will be promoted to △/Y degree, can
It is substantially improved to obtain.
Specifically, detent can't be meshed with the ratchet of ratchet simultaneously, in the present embodiment, and these
Detent 24 is meshed with ratchet 21 in turn, so only one of which positions the engaging tooth 24a of ratchet 24 every time
Can be meshed with a ratchet 21a of ratchet 21, when ratchet rotates (360/X)/Y degree again, just have additionally
The engaging tooth 24a of one detent 24 is meshed with another ratchet 21a of ratchet 21, namely allows and turns
The rotation degree of accuracy of axle 2a brings up to (360/X)/Y degree really.If desired, those skilled in the art are likely to
Allow θ 1, θ 2, θ 3 do some inching, make θ 1 ≠ θ, 2 ≠ θ 3, so will obtain different degree of accuracy.
As shown in Figure 1 and Figure 2, pressure-applying unit 30 include two for clamping ratchet 21 shim pack 31, a pair
Tabular shell fragment 32 and the collar 33 being set on rotating shaft 2a, and one be locked together in rotating shaft 2a end face screw 2b
Interior adjustment bolt 34.Wherein, tabular shell fragment 32 with its two ends contact at end face and the collar 33 of shim pack 31
Bottom surface, user can by rotate adjust bolt 34 the degree of depth that screws togather make the collar 33 produce up or down
Mobile, and then change tabular shell fragment 32 and be applied to the downforce on pad 31, apply adjusting positioning component 20
Resistance at rotating shaft 2a Yu chain guide for use 2.
Accordingly, because detent 24 be through calculating angularly carry out be spaced setting, can be in phase
The rotation degree of accuracy of chain guide for use 2 is improved easily under same number of components.Additionally, the ratchet of ratchet can also set
Put the periphery at ratchet, and detent still can carry out equiangularly spaced arrangement to improve degree of accuracy.
Supplementary notes, as shown in Fig. 2, Fig. 4, Fig. 5, clutch unit 1 is additionally provided with a switch module 50,
It includes support 51 and a control piece 52, and its medium-height trestle 51 is positioned between enclosing cover 40 and stator 25,
And offering groove 51a, control piece 52 is by a plate body 53 and a body of rod 54 is integrally formed constitutes, and plate body 52 can be slided
It is arranged between support 51 and stator 25 dynamicly, and protrudes out downwards four spaced blocks 55 (such as figure
Shown in 5)；The body of rod 54 is upward through groove 51a and is positioned at the opening 41 of enclosing cover 40, and the one end making the body of rod 54 can
Key 60 is stirred with connection one.Therefore, user can utilize hand promotion to stir key 60 and make control piece 52 edge
Groove 51a and produce mobile, when control piece 52 is positioned at one end of groove 51a, block 55 will be at detent
On the path of motion of 24, make these detent 24 can be freely movable and normally play its function (as shown in Figure 4),
But when control piece 52 is positioned at the other end of groove 51a, block 55 will be located in the path of motion of detent 24
And stop that these detent 24 make it be limited in accommodating hole 23, now chain guide for use 2 can relatively originally
Body 10 produces Double-directional rotary.In addition, it is necessary to supplementary notes, the quantity of block 55 can be with detent 24
Quantity and adjust, such as, when the quantity of detent 24 is for the moment, and the quantity of block 55 is only required to be one,
Just can realize switching the function making flowing mode.
The various embodiments described above are merely to illustrate this utility model, the structure of each parts, size, arrange position and shape
Shape all can be varied from, on the basis of technical solutions of the utility model, all former according to this utility model
Manage the improvement and equivalents that individual part is carried out, the most should not get rid of outside protection domain of the present utility model.
