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 the urban public transport system.The screen door that uses in the track traffic is a typical electromechanical integrated product, its platform edge along track traffic is arranged, with station platform and the isolation of locomotive driving tunnel, can prevent that not only personnel and article from falling track, and can reduce the operation energy consumption of air conditioner ventilating system in the station, reduce train operation noise etc. to the impact at station.
Yet in the 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, have brought huge potential safety hazard.
In addition, the sliding door that occurs the on the market at present locking device of closing the door mainly carries out the auxiliary control of opening and closing process by mechanical transmission mechanism, be subject to the impact of structure, the phenomenons such as false lock easily occur, simultaneously, be subject to the restriction of mechanical transmission course, also can occur response lag and the phenomenon such as untimely during unlatching, bring potential safety hazard for the use of sliding door, but also can threaten passenger's the person and property safety.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and can when sliding door is closed, lock sliding door, avoid amateur staff to open sliding door, fall track with being intended to platform side, simple in structure, stable, locking effect is good, installation, maintenance and convenient disassembly, the sliding door self-locking device of fast response time.
The objective of the invention is to be achieved through the following technical solutions: the sliding door self-locking device, it comprises lock body, lock housing, lock body mount pad, be used for driving and the controller of control lock body, be fixedly installed in the dead bolt at sliding door top and be used for the claw of chucking dead bolt; The control signal output of controller links to each other with lock body, lock body is fixedly mounted in the lock housing, lock housing is fixedly installed on the lock body mount pad, the lock housing bottom is provided with sleeve, be slidingly fitted with the connecting rod that matches with sleeve lining in the sleeve, claw is fixedly installed in the bottom of connecting rod, and the top of connecting rod is installed with the magnetic core that matches with lock body;
Dead bolt is fixedly installed on the sliding door by the dead bolt mount pad.
Further, the connecting rod top is provided with defining flange.
Further, claw by about two legs consist of, the bottom that left and right sides leg is fixedly installed in respectively connecting rod consists of inverted U-shaped.
Further, be socketed with spring on the magnetic core outer wall.
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 that matches with skewback a.
The invention has the beneficial effects as follows:
(1) locking sliding door when sliding door is closed can effectively avoid amateur staff to fall track, affect the potential safety hazards such as train driving to the track littering with what be intended to that platform side opens that sliding door causes;
(2) simple in structure, low cost of manufacture;
(3) reasonable in design, stable, locking effect is good, long service life;
(4) installation, maintenance and convenient disassembly;
(5) adopt automatically controlled mode, fast response time;
(6) at closing time, need not to the lock body power supply, lift claw by the skewback b on the extruding of the skewback a on the dead bolt claw; Only need power to lock body when opening the door, thereby lock body attracts lock core to lift claw, finish and can stop power supply after opening the door, claw falls under gravity and spring force effect; The energy consumption of whole self-locking process is very low, has correspondingly reduced the running cost of this device.

The specific embodiment
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, the sliding door self-locking device, it comprises lock body 1, lock housing 2, lock body mount pad 3, be used for driving and the controller 10 of control lock body 1, be fixedly installed in the dead bolt 5 at sliding door 12 tops and be used for the claw 4 of chucking dead bolt 5; The control signal output of controller 10 links to each other with lock body 1, with the "on" position of control lock body 1, during lock body 1 energising magnetic core 6 is had absorption affinity, during lock body 1 outage magnetic core 6 is lost absorption affinity.Lock body 1 is fixedly mounted in the lock housing 2, lock housing 2 is fixedly installed on the lock body mount pad 3, lock housing 2 bottoms are provided with sleeve 8, be slidingly fitted with the connecting rod 9 that matches with sleeve 8 inwalls in the sleeve 8, claw 4 is fixedly installed in the bottom of connecting rod 9, claw 4 by about two legs consist of, the bottom that left and right sides leg is fixedly installed in respectively connecting rod 9 consists of inverted U-shaped, when claw 4 wearing and tearing occur or damages, can for convenience detach and replacing.The top of connecting rod 9 is installed with the magnetic core 6 that matches with lock body 1, and connecting rod 9 tops also are provided with defining flange 13, and defining flange 13 can limit magnetic core 6, connecting rod 9 and claw 4 to the position that falls; Dead bolt 5 is fixedly installed on the sliding door 12 by dead bolt mount pad 11.
Be socketed with spring 7 on magnetic core 6 outer walls, when dead bolt 5 extruding claws 4 lifting claw 4, spring 7 can play the effect of buffering, makes the rising of connecting rod 9 more steady; Just close when closing at sliding door 12, under the effect of the elastic force of spring 7 and self gravitation, claw 4 tenesmus and chucking dead bolt 5; Equally, after finishing the action of opening sliding door 12, spring 7 also can provide elastic force to make claw 4 tenesmus homings.
Dead bolt 5 tongue positions are provided with the inside skewback a14 of the gradient, and the outside at claw 4 tops is provided with the skewback b15 that matches with skewback a14.At closing time, need not to lock body 1 power supply, is liftable claw 4 by the skewback b15 on the extruding of the skewback a14 on the dead bolt 5 claw 4.
Fig. 1 is self-locking device at closing time use state diagram of sliding door 12; As shown in Figure 2, when sliding door 12 closes certain position, the skewback b15 on the skewback a14 extruding claw 4 on the dead bolt 5, thus lift claw 4; As shown in Figure 3, sliding door 12 closes when closing fully, and claw 4 drops under the elastic force of spring 7 and himself action of gravitation, thereby chucking dead bolt 5, therefore, when design, the distance between claw 4 left and right sides leg inwalls should be slightly larger than sliding door 12 and close the distance between dead bolt 5 outer walls of the left and right sides when closing.As shown in Figure 4, when sliding door 12 opened the door, controller 10 controls produced magnetic attraction magnetic core 6 to lock body 1 power supply after lock body 1 energising, and magnetic core 6 when being lifted to certain position, begins to open sliding door 12 by connecting rod 9 lifting claws 4; As shown in Figure 5, after sliding door 12 was opened fully, claw 4 fell under the elastic force of spring 7 and himself action of gravitation.
