The specific embodiment
Embodiment during following the utility model is incited somebody to action by reference to the accompanying drawings is further described:
Shown in Fig. 1 ~ 3, the utility model mainly comprises rotary shaft rack 1, material bearing shelf 2, rotating shaft 3, surface bearing 4, friction lining 5, brake tooth 6, turning gear 7, outer yoke plate 8, extension spring 10, interior yoke plate 11, middle base 12, draw-bar seat 13, pull bar 14, pivoted arm 15, main shaft 16, spindle drum 17 and base 18.
Material bearing shelf 2 lower ends connect rotary shaft rack 1 by bolt, and rotary shaft rack 1 lower end connects main shaft 16, and main shaft 16 is installed in the spindle drum 17 by surface bearing 4.Described spindle drum 17 is fixed on the base 18.
Connect rotating shaft 3 by bearing on the base 18, rotating shaft 3 is positioned at material bearing shelf 2 one sides.Connect pivoted arm 15 in the rotating shaft 3, the pull bar 14 that is rotationally connected on the pivoted arm 15, the front end of pull bar 14 draw-bar seat 13 that is rotationally connected.Described draw-bar seat 13 1 ends connect extension spring 10, the one ends middle base 12 that is rotationally connected.Described extension spring 10 1 ends are fixed on the base 18.
Be rotationally connected on the middle base 12 outer yoke plate 8 and interior yoke plate 11, interior yoke plate 11 is provided with friction lining 5, and friction lining 5 is towards rotary shaft rack 1.Interior yoke plate 11 is provided with brake tooth 6.Rotary shaft rack 1 lower end is provided with turning gear 7, turning gear 7 and brake tooth 6 engagements.
Fixing positioning plate 9 on the described base 18, positioning plate 9 is positioned at outer yoke plate 8 right sides.
Principle of work of the present utility model is: during work, wire rod is placed on the material bearing shelf 2, tightens during the wire rod unwrapping wire and drive rotating shaft 3 rotations.The pivoted arm 15 that is installed in the rotating shaft rotates thereupon.Pivoted arm 15 drives the pull bar 14 that is attached thereto again to left movement, thereby pushing drawing rod seat 13 is to left movement.Draw-bar seat 13 upper ends are provided with extension spring 10, and extension spring 10 pulling draw-bar seats 13 rotate, and middle base 12 is thereupon to left movement.Be connected outer yoke plate 8 on the middle base 12 and interior yoke plate 11 thereupon to left movement, the friction lining 5 on the outer yoke plate 8 breaks away from rotary shaft racks 1, and the brake tooth 6 on the interior yoke plate 11 is thrown off with turning gear 7, and material bearing shelf 2 can rotate smoothly, and the wire rod of tightening relaxes thereupon.Extension spring 10 just retracts original position with rotating shaft 3 like this.Drive middle base 12 thereupon and also move right, outer yoke plate 8 and interior yoke plate 11 are with regard to turning clockwise, and friction lining 5 will be strained rotary shaft rack 1.By friction eceleration, the rotative speed of material bearing shelf 2 will descend, and after a period of time of slowing down, brake tooth 6 also can mesh with turning gear 7, thereby material bearing shelf 2 is stopped the rotation rapidly.It is bad that limiting stopper 9 can prevent effectively that friction lining 5 from drawing, and brake tooth 6 breaks with turning gear 7.
