The utility model discloses an elevator door lock structure, keep off and be fixed in the latch hook of slip door plant including the lock that is fixed in the door frame, the lock keeps off and is provided with the face that blocks that forms the slip door plant of horizontal locking with the cooperation of latch hook, block that the face forms along vertically to the spacing vertical locking mechanism of latch hook.

Furthermore, the longitudinal locking mechanism is a longitudinal limiting groove formed by the blocking surface sinking towards the locking mechanism direction, and the locking hook is embedded into the longitudinal limiting groove in a transverse hooking mode and is longitudinally locked.

Furthermore, the lock catch is a J-shaped catch, and the tail end face of the J-shaped catch is the blocking face.

Furthermore, the longitudinal limiting groove is located in the longitudinal middle of the blocking face, and the longitudinal two ends of the blocking face extend perpendicular to the blocking face respectively and bend towards the locking and blocking side to form a reinforcing part with the tail end fixed on the side face of the locking and blocking flat plate.

Furthermore, the tail end of the reinforcing part is welded and fixed on the side face of the lock catch flat plate.

Furthermore, a longitudinal connecting portion is fixedly connected between the tail ends of the two reinforcing portions, and the longitudinal connecting portion and the reinforcing portions are integrally formed and are welded and fixed on the side face of the lock catch flat plate.

Furthermore, the lock hook is rotatably arranged in the middle of the mounting plate, the reset spring is sleeved above the connecting lock hook and the mounting plate by a screw,

further, the device also comprises a movable roller and a fixed roller which are arranged on the mounting plate through a movable roller shaft, wherein the movable roller and the fixed roller are arranged up and down.

The utility model has the advantages that: the utility model discloses an elevator door lock structure, through keeping off vertical spacing recess at the lock, can be so that the latch hook is more firm when the joint lock keeps off, and the lock keeps off the tail end and seals to be fixed on the support, increases structural strength.

Drawings

The invention will be further described with reference to the following figures and examples:

fig. 1 is a schematic view of the overall structure of the present invention;

FIG. 2 is a schematic view of the latch hook of the present invention in a latched state;

fig. 3 is the structure schematic diagram of the vertical locking mechanism of the lock catch of the present invention.

Detailed Description

Fig. 1 is a schematic view of the overall structure of the present invention; FIG. 2 is a schematic view of the latch hook of the present invention in a latched state; fig. 3 is the structure schematic diagram of the vertical locking mechanism of the lock catch of the present invention. As shown in the figure, the elevator door lock structure in the embodiment comprises a lock catch (1) fixed on a door frame and a lock hook (2) fixed on a sliding door panel, wherein the lock catch (1) is provided with a blocking surface (7) which is hooked with the lock hook (2) to form a transverse locking sliding door panel, and the blocking surface forms a longitudinal locking mechanism (10) which limits the lock hook in the longitudinal direction.

The longitudinal locking mechanism (10) can be a groove or a protruding structure, in the embodiment, the longitudinal locking mechanism (10) is a longitudinal limiting groove formed by a blocking surface which is sunken towards the direction of the lock hook, the lock hook (2) fixed on the lock rod (8) is embedded into the longitudinal limiting groove in a transverse hooking mode and is longitudinally locked, and the danger caused by the position deviation of the lock hook (2) due to improper operation of personnel in the elevator in an accident can be effectively prevented.

In this embodiment, the lock catch (1) is a "J" -shaped catch, and the end surface of the "J" -shaped catch is the blocking surface (7).

In the embodiment, the longitudinal limiting groove (10) is located in the longitudinal middle of the blocking surface, and the longitudinal two ends of the blocking surface respectively extend perpendicular to the blocking surface and bend towards the side of the lock catch to form a reinforcing part (11) with the tail end fixed on the side face of the flat plate of the lock catch (1).
