The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As described in Fig. 1～5, be a preferred embodiment of the present utility model.
A kind of pivoting latch structure that is used on the strongbox, include door-plate 1, latch head 2, slide plate 3, wherein door-plate 1 one sides are movably articulated in doorframe one side of strongbox, also have the latch hole that can lock on the doorframe for latch head inserts, it is a routine techniques, and doorframe and latch hole do not show in drawing.
Spacing at door-plate 1 back side and the relatively door-plate 1 of slide plate 3 laterally moves back and forth, the structure that slide plate 3 is arranged on the door-plate 1 is: roughly have laterally and two side channel holes 31 that are arranged in parallel at the rear positions place at slide plate 3, on door-plate 1 back side, be provided with a projection and and corresponding respectively two projections 11 that match in described two side channel holes 31, movable respectively corresponding side channel hole 31 another sides of back in side channel hole 31 that pass of each projection 11 carry out spacing with nut 12.
Also be provided with on the door-plate 1 and can drive the driving mechanism that slide plate 3 is made lateral displacement, the structure that driving slide plate 3 moves is: comprise that its rotation is arranged on door-plate 1 back side and passes through the shift fork 4 that handle 15 drives its rotations, one end of this shift fork 4 has pushing pin 41, correspondence has the hole 32 that matches with pushing pin 41 on slide plate 3, described pushing pin 41 activities are located in the hole 32.
Move after being provided with on the door-plate 1 under lock-out state, limiting slide plate 3, to keep the lock construction of lock-out state, this lock construction can adopt electronic lock 10 structures, also can adopt mechanical lock structure, and it is the routine techniques on the strongbox, so do not launch to elaborate.
The front end of slide plate 3 has a front side wall 33 that extends downwards, described latch head 2 has two, they rotatably are slidingly connected respectively, and also axial limiting is on slide plate 3 front side walls 33, and latch head 2 can rotate around self axis like this, and latch head 2 also can laterally move with slide plate 3.
Also has a slide bar 6, slide bar 6 is spacing can laterally to be moved with slide plate 3 at slide plate 3 upper surfaces, and also slide plate 3 vertically moves back and forth relatively, slide bar 6 spacing structures on slide plate 3 are: have two guiding slotted eyes 61 that vertically are provided with on slide bar 6, be provided with and corresponding respectively two limited posts 34 that match of the slotted eye 61 that leads at slide plate 3 upper surfaces accordingly, each limited post 34 activity respectively passes each self-corresponding guiding slotted eye 61 back and carries out spacing with locating part 35.
Also be provided with on the door-plate 1 and can drive the driving mechanism that slide bar 6 is made straight skidding, the drives structure that driving slide bar 6 vertically moves is: include eccentric lock 8, and the rocking bar 9 that rotates by eccentric lock 8 drivings, one end of this rocking bar 9 has the promotion post 91 of a projection, on slide bar 6, be provided with a horizontally set accordingly and promote the slotted eye 63 that post 91 matches, described promotion post 91 activities are located in the slotted eye 63, on slide plate 3, have a breach 36, when rotating, activity space is provided for promotion post 91 for rocking bar 9.
Certainly we also can be on increasing on the door-plate bolt structure 13 and following bolt structure 14, it is a prior art, does not just launch to elaborate at this.
The direction that the latch head 2 that laterally is meant sidepiece described in the utility model moves vertically is meant and horizontal perpendicular direction.
Concrete operating principle of the present utility model is as follows:
As Fig. 3, shown in 5, during locking, pull handle, deflection by shift fork 4, pushing pin 41 on the shift fork 4 promotes slide plate 3 reaches, and also with slide plate 3 reaches, latch head 2 enters in the latch hole of doorframe latch head 2, simultaneously, the dead bolt 101 that can limit the electronic lock 10 that moves behind the slide plate 3 stretches out, and moves behind the prevention slide plate 3, and the rotating eccentricity lock 8 again, rocking bar 9 on the eccentric lock 8 rotates, because slide bar 6 is under the position-limiting action of guiding slotted eye 61 and limited post 34, the promotion post 91 on the rocking bar 9 can only promote slide bar 6 relative slide plates 3 and vertically move down, and slide bar 6 drives the plectrum of fixing with latch head 27 and deflects down 90 ° of angles, at this moment, backing pin 5 also rotates 90 ° with latch head 2, sees that from top to bottom backing pin 5 is the level of state, and shelves pin 5 can fasten latch hole tightly, prevent that effectively latch head 2 from by group possibility from latch hole, increasing theftproof.
As Fig. 3, shown in 5, when opening the door, at first the rotating eccentricity lock 8, rocking bar 9 backward rotation on the eccentric lock 8, because slide bar 6 is under the position-limiting action of guiding slotted eye 61 and limited post 34, the promotion post 91 on the rocking bar 9 can only promote slide bar 6 relative slide plate 3 pan-ups, and slide bar 6 drives the plectrum of fixing with latch head 27 and deflects down 90 ° of angles, at this moment, backing pin 5 is 90 ° of angles of latch head 2 backward rotation also, at this moment, see backing pin 5 from top to bottom in vertical state, backing pin 5 no longer fastens latch hole, latch head 2 just can withdraw from latch hole, and the dead bolt 101 of electronic lock 10 withdrawal then moves after no longer limiting slide plate 3, last turning handle, move after pushing pin 41 on the shift fork 4 drives slide plate 3, also with moving behind the slide plate 3, final latch head 2 withdraws from latch hole to latch head 2, unlock, realize opening the door.
