Which the lock body is moved from top to bottom, the lock core passes through the long hole of the trigger plate to complete the locking action of the door, can be fully completed by the own deadweight, can be achieved as long as the trigger plate achieves the locking position without the additional other devices, so the reliability can be enhanced, the locking device for the utility model is provided with a simple, reliable, secure locking device and can realize simple and reliable locking of the sliding door with the pushing and pulling structure type for the platform, the platform screen door, and simplify the structure and reduce the cost.

Description

Locking device for screen door

Technical field

The utility model is a kind of locking device of shield door, and it is used for the shield door of the push-pull door body of platform, railway platform.

Background technology

Along with the extensive use of platform, railway platform screening door, passenger's safety more and more is subjected to the attention of operator.In the shield door of sliding door with push-pull configuration pattern, this passes in and out the passage of unique pattern of train for the passenger, therefore, it is very important that the sliding door under the blocking is carried out reliable locking, breakdown action, and it is opened by revenue passenger in platform side; The shield door locking device structure of using is complicated at present, and cost is also higher.

Summary of the invention

The utility model purpose is to provide a kind of locking device of novel shield door, it can overcome existing shortcoming in the prior art, as far as possible simplified structure and reducing cost makes the platform with push-pull configuration pattern, the sliding door of railway platform screening door can realize simple and reliable locking.

The purpose of this utility model is achieved in that it is fixedly mounted in the shielding header case, comprise electromagnet, it is characterized in that being fixedly connected with lock body on the electromagnet armature, have at least a lock core to be fixedly mounted on the lock body, also be provided with the manual unlocking push rod on the lock body; On sliding door, be installed with trigger board, have slotted hole on the trigger board, be positioned at lock core below.

When sliding door is in the close position, electromagnet outage in the locking device of the present utility model, armature falls by deadweight, drives lock core and drops in the slotted hole of trigger board end, has realized the locking of opposite house body; During unlatching, the electromagnet energising, iron core moves upward, drives lock body and lock core and moves upward, and lock core makes door-plate be in free state by deviating from the slotted hole of trigger board end, has realized the release action.

The utility model can use on single fan sliding door or biparting sliding door.

This locking device is improved aspect reliability, the slotted hole that lock body moves from top to bottom, lock core passes trigger board is finished the locking action of opposite house body, can finish by self deadweight fully, so, need not to increase in addition other devices as long as trigger board reaches locked position and just can realize locking; The end of trigger board is the inclined-plane of arc simultaneously, even in the door-plate closing course, lock body and lock core are in the close position, and also can lock core and lock body upwards be carried out lifting by the inclined plane of arc, lock core can slip into the slotted hole of touch panel end, finishes the action of door lock closure;

The above-mentioned trigger board that is connected with the door body, the termination has the inclined plane of arc; Being used for locking two lock core places is two slotted holes; Trigger board can realize the adjusting of three-dimensional, and long-time use can not influence the reliability of latch mechanism work because of the reduction of precision.

This locking device can put in place and the door control signal of locking to the external system out gate by electric switch by the mode of dynamo-electric interlock, realized door lock assembly unlatching, closed automatic control;

Have with a door body and is connected and the trigger board of move left and right thereupon, in a location triggered electric switch that puts in place of setting, the control signal that out gate puts in place; Have motion from top to bottom and finish the lock body member of a locking, when the locked position that descends, trigger electric switch, out gate locking control signal.The door of this locking device puts in place, the door electrical control of locking, all is to use in pairs by left and right sides door-plate, and wiring is independent, the mounting means of mechanical interlock.The function of dual signal has improved safety, the accuracy of this locking device.

This locking device have can with the supporting manual unlocking action release push rod of finishing platform side and rail side of the manual unlocking device of different types.

Locking device described in the utility model has provides a kind of simple, reliable, safe locking device, has realized the sliding door with the push-pull configuration pattern simple and reliable locking of platform, railway platform screening door, and the purpose that reaches simplified structure, reduces cost.

Description of drawings

Fig. 1 is the front schematic view of shield door and door lock assembly.

Fig. 2 is the Facad structure enlarged diagram of the door lock assembly shown in Fig. 1 when closure state.

Fig. 3 is the side structure schematic diagram of door lock assembly shown in Figure 2.

The specific embodiment

It is following that the utility model is described in more detail with reference to specific embodiment and accompanying drawing thereof.But the utility model is not limited to following example.

Fig. 1 is a front schematic view of using the shield door (comprising platform screen door, railway platform door) of door lock assembly of the present utility model.As shown in the figure, shield door is the divider wall that is provided with along platform edge by the

fixed gate

2,9 of sliding

door

4,8 of opening, closing about two fans and adjacent layout together.Left side slip door leaf 4, right slip door leaf 8 are fixedlyed connected with synchronous cog belt 3 with right gantry crane plate 12 by the left-hand door boatswain chair 11 that is fixed on the door leaf respectively, synchronous cog belt 3 drives the motion that left slip door leaf 4, right slip door leaf 8 are opened, closed by motor 1 about doing under the drive of synchronous cog belt 3.When reaching as shown the position, it is carried out locking by door lock assembly of the present utility model.

The concrete structure of locking device of the present utility model as shown in Figures 2 and 3.Lock housing 17 is fixedly mounted on the superstructure 24 of shield door by connector bolt 21.Electromagnet 15 is housed above the lock housing, and lock body 23 is fixedlyed connected with electromagnet armature.Lock body is provided with lock core 22a and the 22b that is distributed in both sides, and the middle part is installed with release push rod 16.Locking device is provided with two trigger board, promptly left trigger board 13 and right trigger board 14, and left trigger board 13 is fixedlyed connected with left-hand door boatswain chair 11, and right trigger board 14 is fixedlyed connected with right gantry crane plate 12.When the sliding door opening and closing, left and right sides trigger board together moves with the door body.The end of

trigger board

13,14 is inclined plane 25 (a) and 25 (b) with arc, and forwardly is shaped on slotted hole.When left-hand door fan 4, right door leaf 8 run to make position, the lock core 22 on the lock body 23 falls in the slotted hole by self gravitation after electromagnet 15 demagnetizations, and realization is to the together locking of left and right sides door leaf; Adhesive after electromagnet 15 energisings drives lock body 23 and moves upward, and the slotted hole that makes lock core 22 break away from

trigger board

13,14 ends has reached the release to the door leaf that horizontally slips like this, and door-plate can freely be opened.Release push rod 16 is applied thrust upwards, can realize the manual unlocking operation of platform side and rail side.

Be equipped with in this locking device and detect and out gate cuts out the electric switch 18 of the signal that puts in place and the door electric switch 19 of block signal, be grouped into using,, realize dynamo-electric interlock by the action of this signal controlling electromagnet, electrical wiring is independent, reaches the safe, reliable of automatic control.
