Description
Technical field
The present invention relates to a kind of sliding door self-locking device.
Background technology
Along with the fast development of social economy and urban construction level, track traffic is more and more important in urban public transport system.The screen door used in track traffic is a typical electromechanical integrated product, its platform edge along track traffic is arranged, by station platform and the isolation of locomotive driving tunnel, not only can prevent personnel and article from falling track, and the operation energy consumption of air conditioner ventilating system in station can be reduced, the impact on station such as minimizing train operation noise.
But in existing screen door in rail transit system, great majority all do not design sliding door locking device at closing time, and the amateur staff such as passenger or cleaner can open sliding door with being intended to platform side, brings huge potential safety hazard.
In addition, the sliding door occurred on the market at present locking device of closing the door carries out the auxiliary control of opening and closing process mainly through mechanical transmission mechanism, be subject to the impact of structure, the phenomenons such as the false lock of easy generation, meanwhile, be subject to the restriction of mechanical transmission course, during unlatching, also there will be response lag and the phenomenon such as not in time, bring potential safety hazard to the use of sliding door, but also the person and the property safety of passenger can be threatened.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, there is provided one can lock sliding door when sliding door is closed, amateur staff is avoided to open sliding door with being intended to platform side, falling track, structure is simple, stable, locking effect is good, installation, maintenance and convenient disassembly, the sliding door self-locking device of fast response time.
The object of the invention is to be achieved through the following technical solutions: sliding door self-locking device, it comprise lock body, lock housing, lock body mount pad, for drive and control lock body controller, be fixedly installed in the dead bolt at sliding door top and the claw for clamping dead bolt; The control signal of controller exports and is connected with lock body, lock body is fixedly mounted in lock housing, lock housing is fixedly installed on lock body mount pad, lock housing bottom is provided with sleeve, the connecting rod matched with sleeve lining is slidably fitted with in sleeve, claw is fixedly installed in the bottom of connecting rod, and the top of connecting rod is installed with the magnetic core matched with lock body;
Dead bolt is fixedly installed on sliding door by dead bolt mount pad.
Further, connecting rod top is provided with defining flange.
Further, claw is made up of two, left and right leg, and the bottom that left and right leg is fixedly installed in connecting rod respectively forms inverted U-shaped.
Further, magnetic core outer wall is socketed with spring.
Further, the tongue position of dead bolt is provided with the inside skewback a of the gradient, and the outside at claw top is provided with the skewback b matched with skewback a.
The invention has the beneficial effects as follows:
(1) lock sliding door when sliding door is closed, can effectively avoid amateur staff be intended to platform side open sliding door and cause fall track, affect the potential safety hazards such as train driving to track littering;
(2) structure is simple, low cost of manufacture;
(3) reasonable in design, stable, locking effect is good, long service life;
(4) installation, maintenance and convenient disassembly;
(5) automatically controlled mode is adopted, fast response time;
(6) at closing time, without the need to powering to lock body, extruding the skewback b on claw by the skewback a on dead bolt and lifting claw; Only need power to lock body when opening the door, lock body attracts lock core thus lifts claw, and can stop power supply after completing enabling, claw is at gravity and spring force falls downward; The energy consumption of whole auto-lock process is very low, correspondingly reduces the running cost of this device.

Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail, but protection scope of the present invention is not limited to the following stated.
As shown in Figure 1, sliding door self-locking device, it comprise lock body 1, lock housing 2, lock body mount pad 3, for drive and control lock body 1 controller 10, be fixedly installed in the dead bolt 5 at sliding door 12 top and the claw 4 for clamping dead bolt 5; The control signal of controller 10 exports and is connected with lock body 1, to control the "on" position of lock body 1, has absorption affinity when lock body 1 is energized to magnetic core 6, loses absorption affinity during lock body 1 power-off to magnetic core 6.Lock body 1 is fixedly mounted in lock housing 2, lock housing 2 is fixedly installed on lock body mount pad 3, lock housing 2 bottom is provided with sleeve 8, the connecting rod 9 matched with sleeve 8 inwall is slidably fitted with in sleeve 8, claw 4 is fixedly installed in the bottom of connecting rod 9, and claw 4 is made up of two, left and right leg, and the bottom that left and right leg is fixedly installed in connecting rod 9 respectively forms inverted U-shaped, when there are wearing and tearing or damage in claw 4, can for convenience detach and replacing.The top of connecting rod 9 is installed with the magnetic core 6 matched with lock body 1, and connecting rod 9 top is also provided with defining flange 13, and defining flange 13 can limit magnetic core 6, connecting rod 9 and claw 4 to the position fallen; Dead bolt 5 is fixedly installed on sliding door 12 by dead bolt mount pad 11.
Magnetic core 6 outer wall is socketed with spring 7, and when dead bolt 5 extrudes claw 4 lifting claw 4, spring 7 can play the effect of buffering, makes the rising of connecting rod 9 more steady; When sliding door 12 just closes, under the elastic force of spring 7 and the effect of self gravitation, claw 4 drops and clamps dead bolt 5; Equally, after completing the action of opening sliding door 12, spring 7 also can provide elastic force that claw 4 is dropped homing.
Dead bolt 5 tongue position is provided with the inside skewback a14 of the gradient, and the outside at claw 4 top is provided with the skewback b15 matched with skewback a14.At closing time, without the need to powering to lock body 1, by the skewback b15 on the skewback a14 extruding claw 4 on dead bolt 5 and liftable claw 4.
Fig. 1 is self-locking device at sliding door 12 using state figure at closing time; As shown in Figure 2, when sliding door 12 closes certain position, the skewback a14 on dead bolt 5 extrudes the skewback b15 on claw 4, thus lifts claw 4; As shown in Figure 3, when sliding door 12 closes completely, claw 4 drops under the elastic force of spring 7 and the effect of himself gravity, thus clamping dead bolt 5, therefore, when designing, the distance when distance between claw about 4 leg inwall should close slightly larger than sliding door 12 between dead bolt 5 outer wall of the left and right sides.As shown in Figure 4, when sliding door 12 opens the door, controller 10 controls to power to lock body 1, and produce magnetic force after lock body 1 is energized and attract magnetic core 6, magnetic core 6, by connecting rod 9 lifting claw 4, when being lifted to certain position, starts to open sliding door 12; As shown in Figure 5, after sliding door 12 is opened completely, the elastic force of claw 4 at spring 7 and the falls downward of himself gravity.
