The specific embodiment
Below in conjunction with accompanying drawing locking device of the present invention is described in further detail.
As shown in Figure 1, locking device of the present invention can be applied to lock push-and-pull and open and close door and window, and described locking device is provided with the lock body of installing for this device miscellaneous part 11.In the present embodiment, by bearing pin 12 symmetrically arranged latch hook 13 is installed respectively in both sides, described lock body 11 top; Certainly, when slide door or window 10 has only a fan, can latch hook 13 (as shown in Figure 5) be set a side at described lock body 11, its principle is consistent with the situation of two latch hooks 13.Each latch hook 13 comprises hook groove 131 and the link slot 132 that separately is positioned at described bearing pin 12 both sides.Described hook groove 131 matches with the edge of slide door or window 10, and the edge of slide door or window 10 can enter into described hook groove 131, and promotes latch hook 13 around bearing pin 12 rotations; When slide door or window 10 withdraws from described hook groove 131, also can promote latch hook 13 and rotate around bearing pin 12.One section of described hook groove 131 and 10 collisions of described slide door or window can be made as arc surface, thereby reduce the collision of slide door or window 10 and hook groove 131.Simultaneously, described link slot 132 is slidingly connected by bearing pin 141 with an end of lock pin 14, and when described latch hook 13 rotated, described bearing pin 141 slided in described link slot 132, drive described lock pin 14 simultaneously and move, and match with plate 15 at the other end of described lock pin 14.Be provided with latching structure between described plate 15 and the lock pin 14, when slide door or window 10 closures, described lock pin 14 enters locking state under the effect of latching structure, thereby pins slide door or window 10; And in the time will opening slide door or window 10, described latching structure release, described lock pin 14 is in free state, thereby eliminates the locking to slide door or window 10.
Described latching structure comprises the annular groove 142 that is located on the described lock pin 14, be located on the described plate 15 through hole 151 and for described plate 15 provides the spring 16 of pretightning force, as shown in Figure 2.The diameter of described through hole 151 is greater than the diameter of described lock pin 14, thereby makes described lock pin 14 can pass described plate 15.When released state, under the effect of the pretightning force of described spring 16, the inwall of the through hole 151 of described plate 15 is near the outer wall of described lock pin 14; In the process that slide door or window 10 is closed, slide door or window 10 enters the hook groove 131 of described latch hook 13, promote described latch hook 13 and promote described lock pin 14 to move by described latch hook 13, when slide door or window 10 is closed when putting in place, the notch of the hook groove 131 of described latch hook 13 is upwards with slide door or window 10 location, the annular groove 142 of described lock pin 14 moves to through hole 151 positions of described plate 15 simultaneously, under the pressure effect of described spring 16, the edge of the through hole 151 of described plate 15 enters in the described annular groove 142, thereby the described lock pin 14 of described plate 15 chuckings can not move, described lock pin 14 blocks latch hook 13, and described latch hook 13 can not rotate, and reaches the locking purpose.
As shown in Figure 3, be another embodiment of described latching structure, comprise the wedge shaped projection 143 that is located on the described lock pin 14, the spring 16 that is located at the through hole 151 on the described plate 15 and pretightning force is provided for described plate 15.The diameter of described through hole 151 passes described plate 15 greater than the diameter of described lock pin 14 thereby be convenient to described lock pin 14.And the edge shape of described through hole 151 matches with the wedge shape of described projection 143.Same, when released state, under the effect of the pretightning force of described spring 16, the inwall of the through hole 151 of described plate 15 is near the outer wall of described lock pin 14; In the process that slide door or window 10 is closed, when the projection 143 of described lock pin 14 moves to through hole 151 positions of described plate 15, the described spring 16 of described plate 15 compressions of described projection 143 roof pressures, thereby make described lock pin 14 can pass through described plate 15, after described projection 143 passes through described through hole 151, under the effect of the elastic restoring force of spring 16, described plate 15 returns to the origin-location, thereby described projection 143 colludes the edge that is located at described through hole 151, and described plate 15 is locked mutually with described lock pin 14.
Described locking device also is provided with the unlocking structure that drives described latching structure release.Described unlocking structure can be provided with simultaneously for automatic unlocking structure, manual unlocking structure or both.This automatic unlocking structure is an electromagnet 17, when carrying out release, power on for electromagnet 17 and keep certain hour, the described plate 15 of electromagnet 17 pullings, plate 15 is deviate from from the annular groove 142 of lock pin 14, or the projection 143 of lock pin 14 and plate 15 releasing buckles, thereby described lock pin 14 can be by the through hole 151 of described plate 15, the spacing contact of lock pin 14.And manual unlocking structure is a swing rod structure, promote release fork 18 (as the directions of arrow among the figure), promote described plate 15 by described release fork 18, make plate 15 from the annular groove 142 of lock pin 14, deviate from, or the projection 143 of lock pin 14 is removed buckle with plate 15, thereby make the through hole 151 that described lock pin 14 can be by described plate 15, the spacing contact of lock pin 14.After having removed described lock pin 14 spacing, spur described slide door or window 10, rotate and drive described latch hook 13, driving described lock pin 14 by described latch hook 13 moves, break away from latch hook 13 until slide door or window 10, and latch hook 13 remains on this position under the effect of deadweight, wait for the beginning of next circulation, finish release, as shown in Figure 4.
In order to guarantee in releasing process, what described lock pin 14 can transition moves, and described locking device also is provided with the position limiting structure of the extreme displacement of the described lock pin 14 of restriction.Described position limiting structure also can be for being located at the limited block 19 side, the described lock pin 14 of block that described lock pin 14 is connected with described lock body 11.When described lock pin 14 is run into described limited block 19, can not continue to move, guaranteed the extreme position that lock pin 14 is up.Certainly, described position limiting structure can be limited block 20 on the extreme position of unblanking that is located at corresponding described latch hook 13, the described latch hook 13 of block, as shown in Figure 6.When described latch hook 13 turns to the position of described limited block 20, can not be rotated further, thereby described lock pin 14 can not continue to move yet, thereby guarantee the extreme position of lock pin 14.
In order to guarantee that described lock pin 14 can move at its axial direction, also be provided with on the described lock body 11 to be set in the pilot hole (figure does not show) of mobile work guiding described lock pin 14 peripheries, that be described lock pin 14.
