in the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "disposed" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, so to speak, as communicating between the two elements. The specific meaning of the above terms in the present invention can be understood in specific cases for those skilled in the art.

The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.

As shown in fig. 1 and 2, the side-opening type landing door unlocking device of the embodiment includes a door unlocking rod 2, an upper end of which is fixed on a landing door lock assembly 1 and is used for driving a landing door lock assembly latch end 11 to move up and down, a triangular lock assembly 3, which is installed on the landing door assembly and is used for driving the door unlocking rod 2 to swing and lift to one side, and a landing door key 4, which is matched with a lock cylinder of the triangular lock assembly and is used for driving the lock cylinder to rotate, wherein the landing door key is provided with a long rod-shaped key handle rod 41, the key handle rod is perpendicular to a key head 42 of the landing door key, and a tail end of the key head is fixed at one end of the key handle rod in a buckling or welding manner. The utility model discloses an add long rod-like key barre 41, unblank to the superelevation size of opening the door, need not to lengthen locking lever 2 of opening the door, still can moderate degree shorten locking lever 2 of opening the door, improve the mounted position of triangular lock subassembly 3, make layer door unlocking means install in layer door corner department as far as possible, both solved superelevation size of opening the door layer door unblank difficult, hard problem, reduced the operation degree of difficulty of on-the-spot maintainer; but also can avoid influencing the aesthetic degree of the appearance of the elevator landing door.

Specifically, in the present embodiment, the length of the key handle 41 is 290-310 mm, preferably 300mm, and the length can meet the operation requirement of the conventional floor door unlocking with various super-high door opening sizes. The triangular lock assembly 3 adopts a standard triangular lock assembly commonly used for unlocking a landing door in the field, in the embodiment, the landing door lock assembly 1 is installed at the left end of the landing door guide rail frame 5, and the triangular lock assembly 3 is installed at the upper left corner of the left landing door through a first installation hole (not shown) in the left landing door 6. Further, a rectangular limiting block 7 used for limiting the rotation range of the plectrum 31 in the triangular lock assembly is further arranged between the left side layer door 6 and the triangular lock assembly 3, a second mounting hole (not shown) which is consistent with the aperture of the first mounting hole is formed in the center of the limiting block, and the mounting portion of the triangular lock assembly 3 is sequentially penetrated and arranged at the upper left corner of the left side layer door 6 after the second mounting hole and the first mounting hole are fixed. Furthermore, the limiting block 7 is transversely arranged between the left side layer door 6 and the triangular lock component 3 along the long side direction, the middle part of the right side short side of the limiting block is in arc transition and extends to form a limiting part 71 outside the left side layer door, the poking piece 31 can be stopped to rotate on the upper side part of the limiting part 71 along the clockwise direction, can be rotated and abutted against the lower end of the door opening locking rod 2 along the anticlockwise direction and drives the door opening locking rod to swing leftwards to lift the locking hook end 11 of the jacking layer door lock component 1 until the locking hook end is separated from the locking tongue 12, so that unlocking is realized, and the layer door is in an openable state. In the layer door unlocking device, a maintainer holds the key handle rod 41 to rotate within the range of the sector area a, and the angle of the sector area a is the same as that of the rotating range of the plectrum 31 in the triangular lock component 3 and is less than 60 degrees. So, maintainer's the height of lifting the hand (hold key barre at sector area a within range rotation operation in-process, hand off-the-ground height) steerable in the operational range of 1.5 ~ 2m, the handling ease, and when rotating key barre and unblanking, maintainer can the perception lock core turned angle's restriction, can prevent to twist round blindly and damage the lock core.

During specific operation, when the layer door is opened to needs, with layer door key 4's key head 42 and triangular lock subassembly 3's lock core lock, the maintainer holds key barre 41 rotatory along the warning sign direction on the triangular lock subassembly 3, the plectrum 31 that drives the triangular lock subassembly rotates, the plectrum supports and leans on the lower extreme of unlocking lock pole 2 and drives the unlocking lock pole along the lifting of opening the door direction swing, unlocking lock pole 2 upwards jack-up layer door lock subassembly 1's latch hook end 11 is until latch hook end breaks away from spring bolt 12, realize the unblock, can open layer door. When the landing door lock assembly is reset, the door opening lock rod 2 returns to the initial vertical state, and simultaneously the plectrum 31 in the triangular lock assembly rotates along the opposite direction of the door opening to the limiting part 71 which is stopped on the limiting block 7.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
