Description
Technical field
The utility model relates to a kind of sling, especially relates to the movable sling of a kind of gear extruding type.
Background technique
The article that movable sling can be fastened needs are easily fastened.There is following shortcoming in common movable sling: fixed effect is relatively poor, is prone to get loose, and self-lock ability is relatively poor, and structure is complicated, fragile.And the stay cord of the movable sling of existing self-locking can only be strained by single line, operation inconvenience.
Summary of the invention
But the purpose of the utility model provides a kind of stay cord two-wire tension, and operation is convenient, good fixing effect, the movable sling of the gear extruding type that self-lock ability is strong.
The utility model is provided with housing, stay cord and gear squeezing unit; Housing is provided with first lacing hole, second lacing hole and the 3rd lacing hole; Stay cord passes first lacing hole, second lacing hole and the 3rd lacing hole successively; The two ends of stay cord lay respectively at first lacing hole and the 3rd lacing hole is outside, and the limited post of being located in second lacing hole is walked around at the middle part of stay cord; The gear squeezing unit is provided with extruding gear, preloading spring, extruding gear shaft and toggle, and the extruding gear is located in the housing, extruding gear both sides and two side compressions of housing internal chamber wall; Said stay cord passes and is pressed between extruding gear both sides and the housing internal chamber wall both sides; The compressing of preloading spring one end is on the extruding gear, and end on the housing internal chamber wall on preloading spring the other end top, and the extruding gear shaft is slidingly matched with the chute of being located on the housing; Toggle is all established at extruding gear shaft two end part, and toggle exposes housing.
The internal chamber wall both sides of said housing are that inclined-plane and angle are less than 60 °.Can make extruding gear mesh housing internal chamber wall pressure at both sides greater than preloading spring pressure like this.
The shaft axis of said first lacing hole, second lacing hole and the 3rd lacing hole preferably is in same Transverse plane, and said extruding gear shaft is perpendicular to this Transverse plane,
Said first lacing hole and the 3rd lacing hole are positioned at housing one end, and said second lacing hole is positioned at the housing the other end, and 3 lacing holes constitute isosceles triangle and distribute.
Said limited post is preferably parallel with said extruding gear shaft.
Compare with existing technology, the beneficial effect of the utility model is following:
Because under the preloading spring effect, extruding gear both sides can be pressed on stay cord on the housing internal chamber wall, like this because of the frictional force reason, stay cord can the sliding state that tightens up that keeps of pine.When needs are regulated stay cord, can stir toggle backward, toggle drives the extruding gear shaft and behind the chute on the housing, moves; Move after extruding gear shaft band the extruding gear, then push between gear and the housing internal chamber wall and just removed impaction state, have only the arbitrary end in the two ends that spur stay cord like this; Be that the can regulate stay cord is flexible; Unclamp toggle, under the preloading spring effect, extruding gear both sides are pressed on stay cord on the housing internal chamber wall again.This shows that the utlity model has stay cord can two-wayly strain, operation is convenient, good fixing effect, and self-lock ability waits outstanding advantage by force.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation (laterally analysing and observe).
Fig. 2 does not contain the structural representation (vertically analysing and observe) of stay cord for the utility model embodiment.
Embodiment
Referring to Fig. 1 and 2, the utility model is provided with housing 1, stay cord 2 and gear squeezing unit.The shaft axis that housing 1 is provided with first lacing hole 11, second lacing hole 12 and the 3rd lacing hole 13, the first lacing holes 11, second lacing hole 12 and the 3rd lacing hole 13 is in same Transverse plane.First lacing hole 11 and the 3rd lacing hole 13 are positioned at housing 1 one ends, and second lacing hole 12 is positioned at housing 1 the other end, and 3 lacing holes constitute isosceles triangle and distribute.Stay cord 2 passes first lacing hole 11, second lacing hole 12 and the 3rd lacing hole 13 successively; The two ends of stay cord 2 lay respectively at first lacing hole 11 and the 3rd lacing hole 13 outsides, and the middle part of stay cord 2 is exposed second lacing hole 12 and walked around the limited post of being located in second lacing hole 12 14.The gear squeezing unit is provided with extruding gear 31, preloading spring 32, extruding gear shaft 33 and toggle 34 (2 up and down).Extruding gear 31 is located in the housing 1, extruding gear 31 both sides and two side compressions of housing 1 internal chamber wall, and the internal chamber wall both sides of housing 1 are that inclined-plane and angle are less than 60 °.Said stay cord 2 passes and is pressed between extruding gear 31 both sides and the housing 1 internal chamber wall both sides.The compressing of preloading spring 32 1 ends is on extruding gear 31; End at housing 1 internal chamber wall one end on preloading spring 32 the other ends top; Extruding gear shaft 33 is perpendicular to the residing Transverse plane of the shaft axis of 3 horizontal lacing holes; And be slidingly matched with the chute of being located on the housing 1 15, toggle 34 is all established at extruding gear shaft 33 two end part, and toggle 34 exposes housing 1.Said limited post 14 is parallel with said extruding gear shaft 33.
In addition, can establish the projection (not shown) at extruding gear 31 with housing 1 internal chamber wall one end, projection is convenient to the suit location of preloading spring 32.
