Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further detail:

See Fig. 1 to Fig. 6, a kind of elevator hall door lock, comprises hanging hook assembly A1, and hanging hook assembly A1 is provided with shaped groove A11 and mounting hole A12 and the first fixture block A113;

Slide-bar A4 one end and clutch shaft bearing A6 assemble, and the other end, through shaped groove A11, is fixed on a machine link plate (not shown in FIG.) through shaped groove A11 one end;

Rotating shaft A5 one end and the second bearing A7 assemble, the other end is also fixed on a machine link plate, second bearing A7 will load in mounting hole 12, in order to install and use better, at the second bearing A7, installation draw-in groove A71 can be set near mounting hole A12 side, during installation, directly mounting hole A12 sidewall is snapped in and install in draw-in groove;

Hanging hook assembly A1 is also provided with hanger plate A2, and hanger plate A2 left end is provided with hook, links up with and is made up of the first hook A21 at vertical plane and the second hook A22 at horizontal surface, certainly, as long as two hooks are at an angle, and need not as above-mentioned state; Hanger plate A2 right-hand member is connected with the first fixture block A113 and clump weight A114;

Hanging hook assembly A1 is also provided with the cushioning fender A3 for buffering collision of closed below hanger plate A2;

The first groove A10 of the first hook A21 and trench components A0 coordinates, and during use, the first hook A21 can be hooked in the first groove A10;

First beneath trenches is provided with one and second and links up with the groove that A22 coordinates and link up with A110, and groove hook A110 and base portion have been encircled a city the second groove A112;

Also be provided with bump rubber A111 below groove hook A110, during use, bump rubber A111 can coordinate with cushioning fender A3, the impact brought when closing up with lower layer door, and bump rubber A111 adopts elastomeric material to make, and can be plastics or rubber;

Trench components A0 is also connected and fixed by bolt A9 and gate arm A8.

During use, first, external force is used bearing A6 and the first fixture block A113 in the vertical direction to be pressed from both sides point-blank, in this process, can not move because bearing A6 is connected on link plate, the first fixture block A113 can drive hanger plate A2 to rotate counterclockwise centered by the second bearing A7, and the low order end of shaped groove A11 contacts with slide-bar A4, link up with in this process and be just separated from the first groove A10 and the second groove A112, also just open Room door; When Room door closed by needs, this external force eliminated, hanger plate A2 can rotate clockwise under the effect of clump weight A114 centered by the second bearing A7, makes hook again just close Room door with the first groove A10 and the second groove A112;

Above-mentioned external force is that when being opened by car door lock, its two pieces of door tool arms provide, that is only have and open Shi Caineng when car door lock and open Room door lock, first this make Room door lock cannot open from Room Men Yifang, prevent from people from surprisingly opening Room door enter elevator and cause the accident, when the personnel in elevator save oneself be, but can first open car door lock to open Room door from elevator, complete and save oneself.

More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical personnels in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
