The specific embodiment

Below in conjunction with accompanying drawing sliding door lock device of the present utility model is described in further detail.

As shown in Figures 1 to 4, the utility model sliding door lock device comprises the stop pin 1 that is fixed on the sliding door 13, and is fixed on the lock body 12 on the column 14 of sliding door 13.On described lock body 12, be provided with latch hook 2 structures and locking rod 6 structures that match, and the unlocking structure that promotes described locking rod 6 structures.

Described latch hook 2 structures comprise by latch hook rotating shaft 4 and are installed in latch hook 2 on the described lock body 12, and drive first elastic component that described latch hook 2 rotates around described latch hook rotating shaft 4.Described locking rod 6 structures comprise by locking rod rotating shaft 8 and are installed in locking rod 6 on the described lock body 12, and spur second elastic component that described locking rod 6 resets.

Described latch hook 2 comprises latch hook portion 21 that cooperates with described stop pin 1 and the stop section 22 that cooperates with described locking rod 6.Described latch hook portion 21 probably is " ワ " shape, thereby can effectively lock described stop pin 1.Described latch hook portion 21 and described stop section 22 are separately positioned on the both sides of described latch hook rotating shaft 4.In the present embodiment, described first elastic component is the latch hook spring 5 that has applied pretightning force that is arranged on a side of described stop section 22, one end of described latch hook spring 5 is fixedly connected on the described lock body 12, the other end is connected on the stop section 22 of described latch hook 2 or directly is connected in the described latch hook rotating shaft 4, under the tension of described latch hook spring 5, described latch hook 2 has the trend around the rotational of described latch hook rotating shaft 4.But under the block effect of described locking rod 6, described latch hook 2 can't rotate.

Described locking rod 6 comprises and is located at lock part 61 described locking rod rotating shaft 8 one sides, that cooperate with the stop section 22 of described latch hook 2, and be located at described locking rod rotating shaft 8 opposite side, cooperate with described unlocking structure and to promote described locking rod 6 and separate lock section 62 around what described locking rod rotating shaft 8 was rotated.Described second elastic component is that two ends are installed in separating of described locking rod 6 locking rod spring 7 on lock section 62 and the lock body 12, that have certain pretightning force respectively.Under the tension of described locking rod spring 7, described locking rod 6 has the trend of rotating around described locking rod rotating shaft 8, and under the block effect of the stop section 22 of described latch hook 2, described locking rod 6 can't rotate.Described unlocking structure can be for promoting electromagnetic actuator 9 and/or the manual driving lever that described locking rod 6 rotates around described locking rod rotating shaft 8.

In the present embodiment, described sliding door lock device also comprises signaling switch 3 structures, it comprises the switch touching levers that are installed on the described lock body 12 and rotate synchronously with described latch hook 2 by described latch hook rotating shaft 4, and is fixedly mounted on the signaling switch 3 on the described lock body 12.After finishing release, described stop pin 1 can freely break away from latch hook 2, and described switch touching lever triggers described signaling switch 3, sends the indicator lamp signal that opens the door, and the indicator lamp that triggers on the column 14 that is installed in sliding door 13 sends indication.

Sliding door lock device of the present utility model can be installed in the both sides of the sliding door that splits around, and as shown in Figure 5 and Figure 6, has realized that the plane of movement of sliding door and door lock not under conplane situation, can lock or the release sliding door.

Shown in Fig. 7-10, be the schematic diagram of the releasing process of sliding door lock device of the present utility model.As shown in Figure 7, described sliding door lock device is in locking state, described stop pin 1 is locked in the latch hook portion 21 of described latch hook 2, under the effect of described latch hook spring 5, described latch hook 2 has the trend that turns clockwise around described latch hook rotating shaft 4, yet can't rotate under the restriction of the lock part 61 of described locking rod 6; Simultaneously, described locking rod 6 has the trend that rotates counterclockwise around described locking rod rotating shaft 8 under the effect of described locking rod spring 7, can't rotate under the stopping of same stop section 22 in described latch hook portion 21.As shown in Figure 8, when described unlocking structure work, promptly electromagnetic actuator 9 gets electric or manually release driving lever 10 is depressed, and makes described locking rod 6 clockwise rotate, the lock part 61 of described locking rod 6 and the stop section 22 of described latch hook 2 are separated, remove stopping described stop section; This moment, described latch hook 2 rotated around described latch hook rotating shaft 4 clockwise directions, made described stop pin 1 to break away from from described latch hook portion 21, the realization release, as shown in Figure 9.When described latch hook 2 rotated, described signaling switch touching lever 11 triggered described signaling switch 3, sends the indicator lamp signal that opens the door.

And when the door body is closed, as shown in figure 10, described latch hook 2 is under the collision effect of described stop pin 1, overcome the active force of latch hook spring 5, make described latch hook 2 counterclockwise rotate around described latch hook rotating shaft 4, up to the lock part 61 of the stop section 22 of described latch hook 2 and described locking rod 6 snap close mutually, return to state shown in Figure 7, thereby realize the locking of sliding door 13.Simultaneously, signaling switch touching lever 1111 leaves described signaling switch 3, sends sliding door 13 locking indicator lamp signals.
