The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail.

As shown in Figure 1, the utility model mainly comprises installing plate 10, be fixed in locking device 20 and slip jam plate 70 on the installing plate 10, be fixed in driving mechanism 40 that the driving slip jam plate 30 on the installing plate 10 slides, be fixed in the dead bolt 50 on the slip door leaf (not shown), described slip jam plate 30 is at cooperatively interact locking door leaf or open door leaf of the driving lower slider of driving mechanism 40 and locking device 20, described dead bolt 50 under the drive of slip door leaf with cooperatively interact locking door leaf or open door leaf of locking device 20.

Wherein locking device 20 comprises the lock 200 that is fixed on the installing plate 10, two pivot pins 206 that are positioned at lock 200 belows, inserts lock 200 and stretches out lock 200 and the lock shaft 202 that can slide up and down, front end are connected in lock shaft 202 ends, middle part and are connected to two pivot pins 206 and can be around two locking bars 212 of two pivot pins, 206 rotations, lock shaft 202 external peripheral surfaces are provided with annular groove 204, and slip jam plate 30 passes lock 200 and stretches out lock 200 and also can be meshing with each other with annular groove 204.

Two locking bars, 212 front ends are provided with U-lag 2124, and lock shaft 202 ends are provided with cylindricality contiguous block 208, thereby by U-lag 2124 being snapped in cylindricality contiguous block 208 locking bar 212 front ends are connected to lock shaft 202 ends.

Driving mechanism 40 comprises sensor 42, two-way magnet 41 and the gating device (not shown) that is fixed on the installing plate 10, gating device receives that sensor 42 sends controls two-way magnet 41 when locking a door signal or enabling signal or to left movement, two-way magnet 41 drives slip jam plates 30 motion in the same direction to the right.

Wherein the concrete structure of dead bolt 50 is: the rear end of dead bolt 50 is fixed on the slip door leaf by installing hole, and front end is the shape that raises up, and forms two inclined planes, and inboard inclined-plane 51 and inclined-plane, the outside 52, inboard inclined-plane 51 are shorter in length than inclined-plane, the outside 52 length.

The terminal end shape of two locking bars 212 matches with the front end shape of two dead bolts 50, be used to lock door leaf, locking bar 212 ends are inflexed gib head 2120, during the locking of slip door leaf, gib head 2120 slips over inclined-plane 52, the outside and hooks inboard inclined-plane 51, when the slip door leaf was opened, gib head 2120 slips over inboard inclined-plane 51 successively and inclined-plane, the outside 52 separates with dead bolt 50.

For further fixing two locking bars 212, locking device 20 also comprises the spacer pin 210 that is fixed on the installing plate 10 and is positioned at pivot pin 206 belows.Corresponding position, locking bar 212 middle part is provided with downward opening U-shaped groove 2122, cooperatively interacts with spacer pin 210, thereby makes locking bar 212 when pivot pin 206 rotates, and is not easy to depart from, and makes things convenient for door leaf to close and open.

When drive unit 40 because during unexpected cisco unity malfunctions such as electrical system or faults itself, civil power outage, fire, can open door leaf by the release rope hauling device that is connected to slip jam plate 30, spur release stay cord 70 by the operating grip (not drawing among the figure) that is installed on indoor or outdoors specifically, drive the annular groove 204 that slip jam plate 30 withdraws from lock shaft 202 left, door-lock-release, thus sliding door can be manually opened.

As shown in Figure 2, the locking principle of closing the door of the present utility model is as follows:

(a) close will be closed the time when the slip door leaf, the inclined-plane, the outside 52 of dead bolt 50 touches locking bar 212, and locking bar 212 upwards rotates (jam plate 30 that slides this moment is in opening) around pivot pin 206, and the other end drives lock shaft 202 and moves downward simultaneously;

(b) when the slip door leaf continues to cut out, dead bolt 50 continues to central motion with door leaf, the gib head 2120 of locking bar 212 slips over the inclined-plane, the outside 52 of dead bolt 50, under the effect of gravity, rotate around pivot pin 206, fall into the recess (hooking inboard inclined-plane 51) of dead bolt 50, simultaneously, the other end of locking bar 212 drives lock shaft 202 and moves upward, at this moment the door leaf closure;

(c) when the slip door leaf is closed, sensor 42 sends the signal of locking a door for gating device (not drawing among the figure), gating device is controlled two-way magnet 41 and is moved to the right, drive the groove 204 that slip jam plate 30 snaps in lock shaft 202 to the right, lock shaft 202 restrained can not moving, 212 of locking bars can not rotate, and dead bolt 40 is slided to both sides by gib head 2120 restrictions of locking bar 212, and this moment, door lock closed.

As shown in Figure 3, the release of the present utility model principle of opening the door is as follows:

(a) when the slip door leaf was opened, gating device received the enabling signal of sensor, controlled two-way magnet and moved left, drive the annular groove 204 that slip jam plate 30 withdraws from lock shaft 202 left, make lock shaft 202 constraint reliefs, can move up and down, then locking bar 212 can rotate;

(b) dead bolt 50 with the slip door leaf when slide in both sides, the inboard inclined-plane 51 of dead bolt 50 touches the gib head 2120 of locking bar 212, and locking bar 212 can upwards rotate around pivot pin 206, and gib head 2120 slips over inboard inclined-plane 51 and inclined-plane, the outside 52 successively, separate with dead bolt 50, thereby locking is removed.

Characteristics of the present utility model:

1, the utility model is mechanical structure, and is simple in structure, and volume is little, easy for installation, and processing is smart Spend less demanding; Utilize gravity reduction, need not the energy storage parts such as spring, failure rate is low, reliability height.

2, the sliding door power of being locked is come self-lock rod 212, it passes through lock shaft 202 indirectly-actings on slip jam plate 30, and locking and release all are to realize by control slip jam plate 30 movement positions, so the move distance of locking bar 212 and active force and the slip jam plate 30 no direct corresponding relations of locking

3, the release movement travel is short, and releasing force is little, adopts the release stay cord can realize the remote manual release.

4, two-way Self-retaining electromagnet is adopted in automatically controlled locking and release, will remain on this position after the action. Logical Cross director demon design and can realize select time section locking or locking not, reduce the electromagnet action frequency, Increase the service life; Also can be by user selection off working state locking whether.

5, the utility model is provided with slip jam plate 30 position detection sensors 41, can be accurately with the slip jam plate 30 are in locking or non-locking state feedback gating device, avoid misoperation, improve product reliability.
