Embodiment
Fig. 1 and Fig. 2 is referred to, the winch 10 shown in figure includes a frame 20, a reel 30, a drive shaft 40,
And a deceleration device 50.
Reel 30 is rotatably arranged in frame 20, is wound with for a cable wire (not shown).
Drive shaft 40 is arranged in rotationally and coaxially in reel 30, and reel 30 is stretched out at the two ends of drive shaft 40 respectively
Outside, and with wherein one end a power source (not shown) is connected so that drive shaft 40 can be rotated by the driving of power source.
As shown in Figures 2 and 3, deceleration device 50 has a casing 51, a central gear 52, a rim gear wheel 53, Yi Jisan
Planetary gear 54, as shown in the 2nd and 3 figures, casing 51 is fixed on one end of frame 20 and has two relative spacing holes 512 (in fact
As long as on border at least one)；Central gear 52 is located in casing 51 and is connected to the other end of drive shaft 40 so that the sun
Gear 52 can be with the synchronous start of drive shaft 40；Rim gear wheel 53 is located in casing 51 and is connected to one end of reel 30 so that ring tooth
Wheel 53 can be with the synchronous start of reel 30；Planetary gear 54 in the casing 51 and bridle joint in central gear 52 and rim gear wheel 53 it
Between, to provide power laser propagation effect.
Referring again to Fig. 2, arrangement of clutch 12 of the invention includes a knob fixed seat 60, a knob 70, and one from
Seaming element 80.
Knob fixed seat 60 is fixed on one end of frame 20 and a storage tank 62 is formed between frame 20, that will slow down
Device 50 is accommodated in the inner.In addition, knob fixed seat 60 has the notch 64 of a connection storage tank 62.
Knob 70 is located at the notch 64 of knob fixed seat 60 and can be by external force start in an application position P1 (such as Fig. 4 institutes
Show) rotated between an off-position P2 (as shown in Figure 5).
Clutch component 80 has a clutch gear 81, two pilot pins 82, two shell fragments 83, and two elastic components 84.Clutch tooth
Wheel 81 is in the casing 51 of deceleration device 50 and bridle joint is in each planetary gear 54, moreover, the outer peripheral edge of clutch gear 81 has
Multiple detents 812 being distributed in distance；Pilot pin 82 is located between knob 70 and clutch gear 81 and with a head 822
The body portion 824 on head 822 is connected with one, pilot pin 82 is arranged in the spacing hole of the casing 51 of deceleration device 50 by body portion 824
In 512, enable axial movement of the pilot pin 82 stably along itself；There is shell fragment 83 horizontal segment 832 to be connected water with one
Section 834 is stretched in sticking up for flat section 832, and the horizontal segment 832 of shell fragment 83 is fixed on knob 70 towards the one of clutch gear 81 by a screw 85
Sideways so that shell fragment 83 can be with the synchronous start of knob 70, when knob 70 is located at application position P1 as shown in Figure 4, shell fragment 83
Stick up and stretch section 834 and can be resisted against the head 822 of pilot pin 82, when knob 70 is located at off-position P2 as shown in Figure 5, shell fragment
83 stick up, which stretches section 834, can leave the head 822 of pilot pin 82；Elastic component 84 (herein by taking compression spring as an example) is sheathed on pilot pin
82 body portion 824 and it is resisted against between the casing 51 of deceleration device 50 and the head 822 of pilot pin 82, to be located in knob 70
Pilot pin 82 is promoted toward the direction away from clutch gear 81 during the P2 of off-position.
Herein it should be added that, as long as the number of pilot pin 82, shell fragment 83 and elastic component 84 at least one,
If only one pilot pin 82, as long as clutch gear 81 has a detent 812 in theory, if with symmetrical side
If formula sets two pilot pins 82, overall stress can be balanced more.
When cable wire is pulled out from reel 30, knob 70 is turned to off-position P2 as shown in Figure 5 first, made
The head 822 that section 834 leaves pilot pin 82 is stretched in sticking up for shell fragment 83, and pilot pin 82 now can be acted on by the elastic force of elastic component 84
And the detent 812 of clutch gear 81 is left, clutch gear 81 is freely dallied, central gear 52 at this time, OK
Star gear 54, rim gear wheel 53 and reel 30 also can freely be dallied, therefore, and cable wire can be pulled out operation outward by operator.
When to start retracting cable wire, knob 70 is turned to application position P1 as shown in Figure 4 first, makes shell fragment 83
The head 822 for stretching the contact pilot pin 82 of section 834 is stuck up, pilot pin 82 now can be promoted by shell fragment 83 towards the direction of clutch gear 81
And compression elastic piece 84 simultaneously, when pilot pin 82 is inserted in one of detent 812 of clutch gear 81, clutch
Gear 81 will be unable to rotate, then restart power source, make drive shaft 40 start drive central gear 52 rotate, at this time due to
Clutch gear 81 is fixed, so each planetary gear 54 can be rolled around clutch gear 81, and it is synchronous during rolling
Rim gear wheel 53 is promoted, making rim gear wheel 53, band movable reel 30 is rotated again, to reach the effect of retracting cable wire.
In summary, arrangement of clutch 12 of the invention utilizes simply taking between pilot pin 82, shell fragment 83 and elastic component 84
Match somebody with somebody to realize clutch effect, under compared with prior art, the present invention is in start more really without tending to have failure
Problem is produced, to reach the purpose of the present invention.
