In the present embodiment, the structural principle of described hand gear is as shown in Figure 1 and Figure 4, the middle part of push-jump axle 29 is threaded onto in the set hole, lower orientation of locking key 8, and by pin for suppressing metal, 29-1 tightens up, and the two ends of push-jump axle 29 stretch in outward outside housing by the first arcuate socket 4-1-1 and the second arcuate socket 4-2-1.With reference to Fig. 3, lever bracket 21 is realized hinged with housing by second step bolt 25 through riveted tube 25-1.As shown in Figure 5, stop pin 18 is integrated with 19 riveted joints of stop pin support, and stop pin support 19 is realized hinged with lever bracket 21 by first step bolt 22.As shown in Figure 3, lever bracket 21 bottoms are provided with two coaxial apertures, coordinate and realize together side hinged of lever bracket 21 bottoms and front rod 28-1 and rear linking rod 28-2 by step-like hinge 27 and the first spring cotter 26, as shown in Figure 4, another of front rod 28-1 and rear linking rod 28-2 realized hinged with side with the both ends of push-jump axle 29 under the cooperation of the second spring cotter 30.As mentioned above, form a double rocker mechanism by locking key 8, front rod 28-1 and rear linking rod 28-2, lever bracket 21, theory of machines accordingly, locking key 8 is rotating in same direction with the rotation of lever bracket 21.As shown in Figure 1, described the first extension spring 17, its one end is hung on the extension spring support 20 welding lever bracket 21 tops, and the other end is hung in the second rivet pin 15, and the effect of the first extension spring 17 is to compensate the torsional interaction of the first torsion spring 9 to pin key 8 and subdues the harmful effect of the each joint space of double rocker mechanism.Described the second extension spring 24, its one end is hung on pulls on plate 23 set holes, inner end, the other end is hung on hinge 27, the effect of described the second extension spring 24 is, in the time that the mode of surging operates, stop pin 18 does not produce interference, and in the time manually unblanking, the timely bullet of stop pin 18 is from the first recess 4-1-2 and described the second recess.
As shown in Figure 1, the below of described locking key 8 is provided with the signal switch 2 for sensing locking key 8 rotational angles, is provided with and moves vertically and contact with the eccentric arcwall face of locking key 8 lower ends the contact 2-1 coordinating on described signal switch 2.Described contact 2-1 is tight against the arcwall face of locking key 8 lower ends under interior effect of establishing stage clip, and contact 2-1 moves axially with the variation of locking key 8 positions, thus closure and disconnection that signal switch 2 is established circuit in the open locking position of locking key 8 is converted into.
Operation of the present utility model and principle of work are as follows:
Get the mode of surging while unblanking, plunger cylinder 6 passes into high-voltage oil liquid, and plunger 6-1 moves outward, the top of pushing tow locking key 8, locking key 8 overcome the resisting moment of the first torsion spring 9 and contact frictional resistance square and up time to rotation, depart from the restriction to snap close 12 to locking key 8 bottoms, be unlocking condition.While wanting locking, plunger cylinder 6 is placed in to depressurization phase, locking key 8 is the inverse time to rotation under the torsional interaction of the first torsion spring 9, to its underpart, snap close 12 is retrained, and makes fore shaft 12 up time must not occur to rotation, reaches blocking.
Get manual mode while unblanking, Special force application rod is inserted to afterburning excellent intubate 21-1, firmly lower to afterburning rod, lever bracket 21 around hinge 27 up times to rotation, thereby through front rod 28-1, rear linking rod 28-2 and push-jump axle 29 drive locking key 8 up times to rotation, in the time that push-jump axle 29 moves to the first lonely shape hole 4-1-1 and the second arcuate socket 4-2-1 left end position, locking key 8 bottoms have departed from and the contacting of snap close 12, snap close 12 is unlocking condition, now stop the rotation of lever bracket 21, pull plate 23 with hand, after making stop pin 18 snap in the first recess 4-1-2 and the second recess 4-2-2, stop at random afterburning excellent effect, make locking key 8 be maintained at reliably under unlocking condition.As shown in Figure 2, while wanting locking, make the slight up time of lever bracket 21 to rotation with afterburning clubs, up time is to rotation under the effect of the second extension spring 24 for stop pin support 19, and stop pin 18 hightails the first recess 4-1-2 and described the second recess and loses stopping function, removes the effect of afterburning rod, locking key 8 is automatically the inverse time to rotation under the effect of the first torsion spring 9 and the first extension spring 17, while going to final position, the position that rotate in effective restraint fore shaft 12 its underpart, reaches blocking.
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every any simple modification, change and equivalent structure transformation of above embodiment being done according to the utility model technical spirit, all still belongs in the protection domain of technical solutions of the utility model.
