Embodiment
A kind of self-locking pulley of anti-foreign matter, including suspension ring 1, the bottom mounting and fixing support 2 of suspension ring 1, L-shaped is installed on fixed mount 2
Connecting plate 9, the installation rotating shaft 5 of the lower removable of fixed mount 2 installs pulley 6 in rotating shaft 5, and one end of rotating shaft 5 is hinged the one of push rod 4
End, the side of fixed mount 2 open up translot 3, and the other end of connecting plate 9 is hinged fan-shaped eccentric disk 8, and the cambered surface of eccentric disk 8 is positioned at cunning
To take turns above the sides of 6 end faces, one end of bar that is articulated and connected 7 on eccentric disk 8, connecting rod 7 is located at the top of rotating shaft 5, and the one of connecting rod 7
Side is located in translot 3, and end side and the push rod 4 of connecting rod 7 touch.This structure can be new by this practicality by suspension ring 1
After type suspension is fixed, rope is arranged on pulley 6.When rope translational speed within limits when, one end of push rod 4
It is hinged in rotating shaft 5, the gravity of the other end of push rod 4 is more than centrifugal force, as shown in figure 1, push rod 4 will not touch connecting rod 7,
So as to which eccentric disk 8 will not be promoted to touch rope, rope can be transmitted freely up and down.When the translational speed of rope reach one it is critical
During value, the speed of cable tie movable pulley 6 and the rotation of rotating shaft 5 increases, as shown in Fig. 2 the centrifugal force of push rod 4 is more than gravity, push rod 4
Touch connecting rod 7.As the translational speed of rope continues to improve, as shown in figure 3, push rod 4 promotes connecting rod 7 to be moved along translot 3
It is dynamic, so that eccentric disk 8 rotates, eccentric disk 8 is obtained the rope contact on cambered surface and pulley 6 and squeeze rope on pulley 6, hinder
Continuing to move to for rope is stopped, so as to avoid falling object from high altitude.
Fixing groove 10, the holding tank 11 of C-shaped, the first chute 12 and the second chute 13 are opened up in described fixed mount 2 respectively,
The holding tank 11 of C-shaped is communicated with the first chute 12 and the second chute 13 respectively, and supporting plate 14 is set in fixing groove 10, and supporting plate 14 is fixed
On connecting plate 9, rack 16 is installed along its length in the side wall of supporting plate 14, gear 17 is installed in one end of the holding tank 11 of C-shaped,
Gear 17 is engaged with rack 16, and drive 18 is co-axially mounted on gear 17, one end of transmission belt 19 is connected on drive 18, is accommodated
Transition wheel 20 is set in groove 11, the first wedge 21 is set in first chute 12, second wedge 22 is set in the second chute 13,
First wedge 21 opens up the one end on inclined-plane and the inclined-plane of the second wedge 22 touches, the other end cylinder lever connecting rod of the first wedge 21
23, fixed mount 2 is stretched out in the end of pull bar 23, spring 24 is set on pull bar 23, the side wall of the first chute 12 is distinguished at the both ends of spring 24
It is fixedly connected with the first wedge 21, spring 24 gives the thrust of the first wedge 21 all the time, and the other end of transmission belt 19 bypasses transition
Wheel 20 is connected with one end of the second wedge 22, and the other end of the second wedge 22 is fixedly connected with extension spring 25, and extension spring 25 is fixed on C
In the side wall of holding tank 11 of shape, the pulling force of the second wedge 22 is given in extension spring 25 all the time, and the sidepiece of the second wedge 22 installs limited block 26,
The side wall of supporting plate 14 opens up stopper slot 27, and limited block 26 is located in stopper slot 27.This structure is connected in connecting plate 9 with fixed mount 2
When, promote supporting plate 14 supporting plate 14 is entered fixing groove 10, during, the rack 16 on supporting plate 14 rotates with moving gear 17,
So that drive 18 drives the second wedge 22 to move by transmission belt 19, the inclined-plane of the second wedge 22 is wedge-shaped along first
During the inclined-plane movement of block 21, the limited block 26 on the second wedge 22 enters in the stopper slot 27 on supporting plate 14, and supporting plate 14 is consolidated
It is scheduled in fixing groove 10, so as to which connecting plate 9 is fixed on fixed mount 2.When dismantling supporting plate 14, pull bar 23 is pulled, makes the second wedge
Limited block 26 on shape block 22 departs from stopper slot 27, and under the pulling force effect of extension spring 25, the homing of the second wedge 22, passes
Dynamic band 19 is rotated backward by drive 18 with moving gear 17, supporting plate 14 is left fixing groove 10, so as to it is convenient by connecting plate 9 with
Fixed mount 2 separates.The thickness of drawstring, is set not on fixed mount 2 in this structure convenient size and pulley 6 according to pulley 6
Same connecting plate 9 and diverse location, the eccentric disk 8 of size, so as to which the drawstring on pulley 6 is choked.
Pull bar 23, which stretches out, installs baffle plate 28 on the end of fixed mount 2.This structure can avoid pull bar 23 completely into
One chute 12, and convenient pulling pull bar 23.
The described sidepiece of limited block 26 sets inclined-plane, and the side wall of stopper slot 27 sets inclined-plane, the inclined-plane and limit of limited block 26
The inclined-plane of position groove 27 is engaged.This structure can be when limited block 26 enters stopper slot 27, and both inclined-planes, which are bonded to each other, to be carried
For buffering, limited block 26 is avoided to produce collision with stopper slot 27.
The technical solution of the utility model is not restricted in the range of embodiment described in the utility model.This practicality is new
The technology contents of the not detailed description of type are known technology.
