Number in the figure: 1 holder, 2 flat keys, 3 springs, 4 pins, 5 transiting rods, 6 nut seats, 7 screw mandrels, 8 screw rodb bases, 9 spline seats, 10 limiting plates, 11 rules, 12 spline pins, 13 pointers.
Detailed description of the invention
See Fig. 1, Fig. 2 and Fig. 3, in the present embodiment, the version of rapid adjustment rotation preventive mechanism is: arrange that holder 1 top is fixed disk, bottom is lead; Only transposase 19 is sleeved on lead, and can slide axially along lead, holder 1 be only connected with the pin 4 along fixed disk circle distribution between transposase 19, pin 4 is set with spring 3; Screw rodb base 8 is fixedly installed in the side of stopping transposase 19, screw rodb base 8 is provided with the screw mandrel 7 in level, screw mandrel 7 two sections in left and right is set to the threaded rod of different rotation direction, the threaded rod of different rotation direction is equipped with a pair nut seat 6, form screw nut driving structure, rotary screw rod 7 can make a pair nut seat 6 move in opposite directions; Nut seat 6 connects transiting rod 5 in cantilevered fashion, spline pin 12 run through the middle part pin-and-hole of transiting rod 5 and the base plane protruding from transiting rod 5 as pin rod; The epimere of spline pin 12 is set to "T"-shaped slide block, in the corresponding position, bottom surface of stopping transposase 19, "T"-shaped chute is set, "T"-shaped skid is engaged in "T"-shaped chute, "T"-shaped chute and screw mandrel 7 are parallel to each other, the fit form of "T"-shaped slide block and "T"-shaped chute is adopted to install simply, reliable in action.
In concrete enforcement, the outer circumference surface of lead axially arranges a pair flat key 2 along lead, it is a pair keyway that the correspondence position stopping transposase 19 is equipped with, and flat key 2 is embedded in the keyway of only transposase 19, forms the guide frame of only transposase 19 in the vertical direction movement.Pointer 13 is extended in the front end of transiting rod 5, the only transposase 19 of correspondence position is provided with rule 11, the position of spline pin 12 is indicated with pointer 13 and rule 11, only transposase 19 is installed at two ends and is installed with limiting plate 10 respectively, comes off in case spline pin causes because manual operation is improper at the two ends of T-shape chute.
In concrete enforcement, screw mandrel 7 adopts 30 ° of trapezoidal screws, and adopts small―gap suture to coordinate between each driving member, effectively can ensure to tighten axle operationally centre-to-centre spacing self-locking, and not be moved.
In flange nut rundown process, after needing the replacement of products tightened, the flange centre-to-centre spacing that will tighten on it also changes, and now needs the centre-to-centre spacing of change a pair spline pin 12.Now, hand rotation screw mandrel 7, a pair nut seat 6 produces and moves in opposite directions on screw mandrel 7, and then drives spline pin 12 to move in opposite directions along "T"-shaped groove by transiting rod 5, realizes the adjustment of the centre-to-centre spacing of a pair spline pin 12.After centre-to-centre spacing is adjusted, trapezoidal screw realizes self-locking, and spline pin reaches duty.
