5, under the prerequisite of guaranteed performance, effectively reduce cost of production, improved the market competitiveness.
The accompanying drawing explanation
Fig. 1 is perspective view of the present utility model;
The A that Fig. 2 is Fig. 1 is to the partial structurtes enlarged diagram.
The specific embodiment
For ease of operation and maintenance, door lock mechanism is arranged on the outside end face of two escape doors that match usually, like this, can not affect intermeshing, sealing between the escape door inner face, simultaneously, is convenient to the passenger and is controlled by track end.Below in conjunction with accompanying drawing 1, Fig. 2, the utility model is described in further detail:
Described in the utility model a kind of for the escape door door lock mechanism on half high shield door, comprise holder 1, sliding shoe unit and swinging block unit.Holder 1 is fixed on the outside end face of emergent every body, and holder 1 is platy structure, and holder 1 is for supporting sliding shoe unit and swinging block unit.The sliding shoe unit is slidably connected on holder 1, and the sliding shoe unit can be along the upper and lower slip of holder 1, with unlatching or the closing process that completes the escape door door lock.The swinging block unit matches with the sliding shoe unit, and the swinging block unit slides for triggering the sliding shoe unit.
In concrete structure, the sliding shoe unit comprises sliding shoe 3, check lock lever 7, front riser 8 and side riser 9 four parts.Sliding shoe 3 is tabular, is provided with the stopper slot 10 of arc near the upper end of sliding shoe 3, and stopper slot 10 is comprised of one section deep-slotted chip breaker and the straight trough that is positioned at the almost vertical direction of deep-slotted chip breaker one end, between straight trough and deep-slotted chip breaker, is provided with transition.Sliding shoe 3 is slidably connected on holder 1 by three equally distributed keyways and connecting axle.Front riser 8 and side riser 9 are separately positioned on the position near sliding shoe 3 middle parts as the corresponding mechanism that lock core is opened and push rod is opened.For guaranteeing the locking quality, check lock lever 7 is vertically fixed on the above-below direction of sliding shoe 3 rear sides, and check lock lever 7 is given prominence in the external side of door, and check lock lever 7 is corresponding with the locked groove of escape door, and locked groove is usually located on the column of escape door.
The swinging block unit comprises swinging block 2, locking frizzen 4, locating shaft 6 and torsion spring 5.Swinging block 2 is tabular, and swinging block 2 is connected on holder 1 by central axis, and swinging block 2 is positioned at sliding shoe 3 tops, and swinging block 2 can swing in vertical direction along central axis.Locking frizzen 4 and locating shaft 6 are vertically fixed on respectively the upper/lower terminal of swinging block 2 rear sides, and locking frizzen 4 is given prominence in the external side of door, and locking frizzen 4 is for triggering sliding shoe 3 motions.Locating shaft 6 outer ends are inserted in the stopper slot 10 of sliding shoe 3, by the motion in stopper slot 10, drive sliding shoe 3 to move up and down.Torsion spring 5 is located on central axis, and the torsion end of torsion spring 5 acts on the outside of locking frizzen 4, with restriction locking frizzen 4, outwards too tilts and produces enough inside thrust.For guaranteeing that swinging block 2 lower ends swing in controlled range, prevent that overswing from causing damage or stuck phenomenon to sliding shoe 3, also be provided with backstay 11 on the holder 1 in swinging block 2 outsides, lower end.
In real work, when escape door need to be closed, emergent every body moves horizontally, give prominence to locking frizzen 4 pressurizeds external at door, drive swinging block 2 tops and swing laterally certain angle, the locating shaft 6 that is positioned at swinging block 2 lower ends is turned on the straight trough position by the deep-slotted chip breaker end of stopper slot 10, sliding shoe 3 loses the support of locating shaft 6, sliding shoe 3 is at self gravitation effect down sliding, and check lock lever 7 slips in the locked groove on the escape door column, completes the escape door closing process.Now, swinging block 2 positions are fixed, and after torsion spring 5 distortion, locking frizzen 4 outsides are produced to constant inside thrust.
When needs are opened escape door, no matter be that the staff opens from the lock core opening mechanism of platform side, or the passenger is opened by the push rod opening mechanism of rail side, capital is corresponding upwards lifts certain distance by front riser 8 or side riser 9 by sliding shoe 3, check lock lever 7 is deviate from locked groove, the escape door release; Simultaneously, swinging block 2 to the intrinsic deflection certain angle, drives locating shaft 6 and is transferred to the deep-slotted chip breaker end by the straight trough end under the effect of torsion spring 5 torsion ends, sliding shoe 3 after 6 pairs of risings of locating shaft is produced and support, and has avoided sliding shoe 3 again to fall, emergency door release.Be subject to the effect of torsion spring 5, swinging block 2 positions are fixed again relatively, have guaranteed that emergent door lock is all the time in unlocking condition.
So repeatedly, can constantly complete the unlatching of escape door or close, simplify operating process, guarantee operating reliability.
