Detailed description of the invention
See Fig. 1, a kind of worm and gear winch clutching device structure that the utility model relates to, described structure includes the reel 6 be set up on capstan winch support 7, concretely, capstan winch support 7 is divided into two supports in left and right, the two ends of reel 6 are set up on two supports in left and right respectively, clutch rod 2 and transmission shaft 5 is plugged with in described reel 6, and the central axis of clutch rod 2 and transmission shaft 5 is located along the same line, the left socle of described capstan winch support 7 is plugged with a bar handle 1, this bar handle 1 is hinged with the left end of clutch rod 2, preferably, the left socle of above-mentioned capstan winch support 7 has a zigzag positioning groove d, above-mentioned bar handle 1 is inserted in this zigzag positioning groove d, and the middle part of bar handle 1 is held on the fulcrum C of the left socle of capstan winch support 7, thus make when stirring in zigzag positioning groove on operating handle 1, operating handle 1 can promote clutch rod about 2 translation as a lever under the effect of fulcrum C, and clutch rod 2 is set with retracing spring 3, this retracing spring 3 one end is placed on the left socle of capstan winch support 7, the other end is placed on clutch rod 2, described transmission shaft 5 is equipped with a clutch spline housing 4 by key adapter sleeve, between this clutch spline housing 4 with reel 6 inwall, key is connected, and clutch spline housing 4 is connected with the right-hand member snap-fit engagement of clutch rod 2,
Concretely, described transmission shaft 5 is provided with male splines a, and clutch spline housing 4 is set on this male splines a, and the inner tube wall of described reel 6 is provided with female splines b, and clutch spline housing 4 is inserted in this female splines b;
The right-hand member of described clutch rod 2 is movably installed with a snap ring, and (this snap ring can rotate around the central axis of clutch rod 2, but can not along the centerline axis parallel of clutch rod 2), the left side of described clutch spline housing is connected with above-mentioned snap ring, thus make clutch rod 2 parallelly can pull clutch spline housing 4, and when clutch spline housing 4 works, when transmission shaft 5 drives reel 6 to rotate, clutch rod 2 can not be subject to the impact of now rotational force.
Principle of work of the present utility model is: bar handle 1 is equivalent to a lever, fulcrum c is positioned on left socle, the spring force that can overcome retracing spring 3 when controlling bar handle 1 pulls clutch rod 2, clutch spline housing 4 is slided along male splines a on transmission shaft 5, when clutch spline housing 4 skids off the female splines b engaged with reel 6, reel 6 is separated with transmission shaft 5, achieves winch clutching and throws off; Now rested on the Z-shaped groove of left socle by bar handle 1, namely capstan winch is in disengaged condition; When capstan winch needs twisted rope operation, bar handle 1 is slipped away Z-shaped anchor point, clutch spline housing 4 can automatically reset to engagement with clutch rod 2 under retracing spring 3 spring-force driven dual; By Z-shaped groove, bar handle is locked again.
In addition: it should be noted that above-mentioned detailed description of the invention is only a prioritization scheme of this patent, any change that those skilled in the art does according to above-mentioned design or improvement, all within the protection domain of this patent.
