Summary of the invention
The purpose of this utility model is to provide a kind of locking releasing device for articulated mechanism.
For achieving the above object, the utility model can take following technical proposals:
Locking releasing device for articulated mechanism described in the utility model, comprise first connecting rod and second connecting rod that end is hinged, the other end and the frame of described first connecting rod are hinged, described frame is hinged with shift fork, the other end of described first connecting rod through described shift fork upper and lower moving tooth be hinged with frame; The lower wall of described first connecting rod is provided with the first spacing block set, and described first spacing block set contacts with the second spacing block set face be arranged in second connecting rod lower wall, and the upper side wall of described second connecting rod is provided with locking projection; The first connecting rod upper side wall being positioned at the upper and lower moving tooth outside of described shift fork is provided with engaging lug, described engaging lug is hinged with locking bar by rotating shaft, one end of described locking bar extends between the upper and lower moving tooth of shift fork, and the other end extends to and contacts with described locking projection; Described locking bar is provided with Returnning spring.
Described first connecting rod offers through-hole groove between described engaging lug to frame, and the width of described through-hole groove and length are greater than width and the length of locking bar respectively.
The end that described locking bar contacts with described locking projection is hinged with roller, and described roller substitutes locking bar and contacts with locking projection.
The utility model has the advantage of and effectively can ensure that between articulated mechanism two hinge bar, relative angle does not change when bearing larger pulling force or pressure, the structures such as mounting hole are increased without the need to extra in frame, substantially increase the strong rigidity of frame, save the space of installing and moving, catching phenomenon is there will not be during motion, only need a power to drive shift fork can complete unblock and the reset of this articulated mechanism, reduce operation easier.

Embodiment
As shown in Figure 1, 2, 3, locking releasing device for articulated mechanism described in the utility model, comprise first connecting rod 1 and second connecting rod 2 that end is hinged, the other end and the frame of this first connecting rod 1 are hinged, frame is hinged with shift fork 3, the other end of first connecting rod 1 through shift fork 3 upper and lower moving tooth be hinged with frame; The lower wall of first connecting rod 1 is provided with the first spacing block set 4, first spacing block set 4 contact with the second spacing block set 5 be arranged in second connecting rod 2 lower wall, the upper side wall of second connecting rod 2 is provided with locking projection 6; First connecting rod 1 upper side wall being positioned at the upper and lower moving tooth outside of shift fork 3 is provided with engaging lug 7, engaging lug 7 is hinged with locking bar 8 by rotating shaft, locking bar 8 prolongs the axial rotation motion of rotating shaft, one end of locking bar 8 extends between the upper and lower moving tooth of shift fork 3, and the other end extends to and contacts with locking projection 6; It can be the torque spring be sleeved in rotating shaft that locking bar 8 is provided with Returnning spring 9(Returnning spring 9, also can be arranged on the draught spring on locking bar 8 downside from rotating shaft to locking projection 6 direction that extend along, can also be arranged on the pressure spring on locking bar 8 downside from rotating shaft to shift fork 3 direction that extend along).
First connecting rod 1 offers through-hole groove 10 between engaging lug 7 to frame, and the width of through-hole groove 10 and length are greater than width and the length of locking bar 8 respectively, are convenient to one end of locking bar 8 when shift fork 3 presses to first connecting rod 1 through first connecting rod 1.
The end that locking bar 8 contacts with locking projection 6 is hinged with roller 11, and roller 11 substitutes locking bar 8 and contacts with locking projection 6; When unlocking or reset, roller 11 can reduce the friction produced between locking projection 6, is convenient to unlock or reset.
As shown in Figure 4,5, operating principle of the present utility model is as follows:
The locking states of mechanism:
First spacing block set 4 and the second spacing block set 5 compress mutually, one end and the locking projection 6 of locking bar 8 compress mutually, Returnning spring 9 applies active force to locking bar 8, prevent locking bar 8 and locking projection 6 from departing from, now mechanism completes locking, and the relative angle between first connecting rod 1 and second connecting rod 2 can not change because of the pulling force of two ends generation or pressure.
The unlocking motion process of mechanism:
Shift fork 3 is under the drive of power, rotate, on it, moving tooth presses to one end of locking bar 8 downwards, overcome the elastic force of Returnning spring 9, the rotating shaft of locking bar 8 on engaging lug 7 is rotated, and the other end of locking bar 8 upwards lifts, and removes the contact of locking bar 8 and locking projection 6, complete the unblock of mechanism, the relative angle between first connecting rod 1 and second connecting rod 2 can be changed.Now shift fork 3 continues to rotate, moving tooth upper limb is made to press to the upper side wall of first connecting rod 1, first connecting rod 1 is under the downward pressure effect of upper moving tooth, move downward around the articulating point with frame, now the first spacing block set 4 and the second spacing block set 5 depart from, relative angle between first connecting rod 1 and second connecting rod 2 changes, and completes the unlocking motion process of connecting rod.
The homing action process of mechanism:
Shift fork 3 is to counter-rotation, it is set aside tooth and moves upward, press to the lower wall of first connecting rod 1, first connecting rod 1 is moved upward around the articulating point of frame, and the relative angle between first connecting rod 1 and second connecting rod 2 returns to the original state of mechanism's locking gradually, simultaneously, upper moving tooth leaves locking bar 8, locking bar 8 completes reset under the elastic force effect of Returnning spring 9, and locking bar 8 is contacted again with locking projection 6, and the first spacing block set 4 contacts compression again with the second spacing block set 5 simultaneously.Complete mechanism to reset.
