A torsion spring is installed at the position of the gap between the mounting seat and the knife arm on the outer surface of the rotating shaft.

[0004] In the above-mentioned utility model patent, when assembling or maintaining the elevator door lock, there is a situation where the staff needs to adjust the installation position of the door ball so that it can be offset under the drive of the door knife. When adjusting the position of the door ball, since the door ball is connected to the locking hook and the components of the electrical switch are connected to the locking hook, after the staff adjusts the position of the door ball, it is also necessary to make adaptive adjustments to the locking seat and the components of the electrical switch. The above installation and debugging process has the defects of having more adjustment objects and a large amount of work. Summary of the Utility Model

[0005] In order to improve the situation in the related technology where there are more adjustment objects and a large amount of work during the installation and debugging process, this application provides an elevator door lock that is convenient for installation and debugging, so as to reduce the adjustment objects and thus reduce the workload of the staff during installation and debugging.

[0006] This application provides an elevator door lock that is convenient for installation and debugging, and adopts the following technical solutions:

[0007] An elevator door lock that is convenient for installation and debugging includes a substrate and a lock plate. One end of the substrate extends to form a locking hook. The substrate has a rotation center. The lock plate is provided with a lock hole. The substrate rotates along the axis of the rotation center so that the locking hook rotates and is engaged with the lock hole. A first connecting plate is detachably connected to the front side of the substrate. The substrate is provided with a first positioning member for adjusting the horizontal installation of the first connecting plate. A door ball group is arranged on the front side of the first connecting plate. An electrical switch is installed on the front side of the lock plate. The electrical switch is connected to the locking hook.

[0008] Optionally, the electrical switch includes an electrical static contact and an electrical moving contact. A second connecting plate is provided on the front side of the substrate. The electrical static contact is installed on the front side of the locking plate, and the electrical moving contact is installed on the second connecting plate. The substrate is provided with a second positioning member for installing the second connecting plate.

[0009] Optionally, the first connecting plate includes a connecting portion and an assembling portion integrally formed with the connecting portion. The connecting portion is installed on the upper edge of the substrate through the positioning member, and the assembling portion is located on the front side of the substrate. The door ball group is installed on the side of the assembling portion away from the substrate.

[0010] Optionally, the door ball group includes an upper door ball and a lower door ball. The upper door ball and the lower door ball are circumferentially distributed around the axis of the rotation center. The upper door ball is located on the upper edge of the rotation center, and the lower door ball is located on the side of the rotation center away from the locking hook.

[0011] Optionally, the rotation center is a rotating shaft. The rotating shaft penetrates through the substrate and is rotatably connected to the substrate. A torsion spring is sleeved on one end of the rotating shaft away from the first connecting plate. A support column is provided on the substrate on the side of the rotating shaft close to the locking hook. One end of the torsion spring is connected to an external hanging plate, and the other end of the torsion spring is hung on the outer surface of the support column.

[0012] Optionally, the first positioning member includes a first fastening bolt. The substrate is provided with a first strip-shaped hole. The first connecting plate is fixed to one end of the substrate away from the locking hook through the first fastening bolt.

[0013] Optionally, the second positioning member includes a second fastening bolt. The substrate is provided with a through hole. The second connecting plate is fixed to one end of the substrate close to the locking hook through the second fastening bolt.

[0014] By adopting the above technical solution, when the upper door ball and the lower door ball are clockwise offset under the extrusion of the door knife, the substrate is driven to rotate clockwise around the rotation center, so that the locking hook is lifted and disengaged from the locking hole. At this time, the electrical moving contact is disengaged from the electrical static contact. When the door knife is released, under the action of the torsion spring, the substrate resets, and the locking hook falls into the locking hole under the action of gravity, and the electrical moving contact is then lapped on the electrical static contact. During the actual installation and debugging process, since the door ball group is installed on the substrate through the first connecting plate, after the staff completes the installation of the electrical switch and the substrate, only the position of the first connecting plate relative to the substrate needs to be adjusted and installed, and the position of the door ball group can be debugged independently, reducing the engineering quantity.

[0025] Specifically, in this embodiment, the locking hook 3 is integrally provided with the substrate 1, and the door ball group 7 is separately provided from the substrate 1, avoiding the situation where the positions of the locking hook 3 and the electric switch 8 need to be adjusted together due to the improper position of the door ball group 7 during the debugging process. By modularizing the elevator door lock, the purpose of improving the installation and debugging efficiency is achieved, and the workload of installation and debugging for the staff is reduced.

[0026] In a preferred embodiment of the present invention, the electric switch 8 includes an electric static contact 81 and an electric moving contact 82.

The door ball group 7 is installed on the side of the assembling portion 62 away from the substrate 1.

[0028] Specifically, in this embodiment, the connecting portion 61 and the assembling portion 62 are formed by bending and die-casting a single plate member. Among them, the connecting portion 61 is located on the upper edge of the substrate 1 and is fixedly installed through a positioning member. The assembling portion 62 is located on the front side of the substrate 1 and is arranged parallel to the substrate 1, so that the door ball group 7 installed on the front side of the assembling portion 62 is parallel to the substrate 1, making the position of the door ball group 7 more intuitive and convenient to observe during actual debugging.

[0029] In a preferred embodiment of the present invention, the door ball group 7 includes an upper door ball 71 and a lower door ball 72. The upper door ball 71 and the lower door ball 72 are circumferentially distributed around the axis of the rotation center 4. The upper door ball 71 is located on the upper edge of the rotation center 4, and the lower door ball 72 is located on the side of the rotation center 4 away from the locking hook 3.

[0030] Specifically, in this embodiment, during the process of clamping the door knife, the upper door ball 71 receives a rightward acting force applied by the door knife, and the lower door ball 72 receives a leftward acting force applied by the door knife, causing the door ball group 7 to rotate clockwise around the rotation center 4, realizing the offset of the door ball group 7 and then controlling the locking hook 3 to lift and disengage from the locking hole 5, and the electric switch 8 is turned off.

[0031] In a preferred embodiment of the present utility model, the rotation center 4 is selected as a rotating shaft, the rotating shaft is installed through the substrate 1, a torsion spring 10 is sleeved on one end of the rotating shaft away from the first connecting plate 6, a support column 11 is arranged on the substrate 1 on the side of the rotating shaft close to the locking hook 3, one end of the torsion spring 10 is connected to an external hanging plate, and the other end of the torsion spring 10 is hung on the outer surface of the support column 11.

[0032] Specifically, in this embodiment, by arranging the torsion spring 10 to assist the elevator door lock to reset, the reliability of the elevator door lock is improved.

[0033] Among them, a hanging plate is installed on the surface of the landing door of the elevator, the elevator door lock is installed on the hanging plate, and the hanging plate is provided with a hanging plate hole for inserting one end of the torsion spring 10.

[0034] In a preferred embodiment of the present utility model, the first positioning member includes a first fastening bolt 12, the substrate 1 is provided with a first strip-shaped hole 13, and the first connecting plate 6 is fixed to one end of the substrate 1 away from the locking hook 3 through the first fastening bolt 12.

[0035] Specifically, in this embodiment, by arranging the first strip-shaped hole 13, during the debugging process, the staff can control the first connecting plate 6 to slide along the first strip-shaped hole 13 to adjust the horizontal position, and during the debugging process, the positions of the locking hook 3 and the electrical switch 8 are not affected, thereby reducing the debugging workload.

[0036] In a preferred embodiment of the present utility model, the second positioning member includes a second fastening bolt 14, the substrate 1 is provided with a through hole 15, and the second connecting plate 9 is fixed to one end of the substrate 1 close to the locking hook 3 through the second fastening bolt 14.

[0037] Specifically, in this embodiment, the electric moving contact 82 is installed on the second connecting plate 9, the connection structure between the second connecting plate 9 and the substrate 1 is simple, and the installation method is relatively simple, improving the assembly efficiency.

[0038] In summary, when the upper door ball 71 and the lower door ball 72 are clockwise offset under the extrusion of the door knife, the substrate 1 is driven to rotate clockwise along the rotation center 4, so that the locking hook 3 is lifted and separated from the lock hole 5, and at this time the electric moving contact 82 is separated from the electric static contact 81; when the door knife is released, under the action of the torsion spring 10, the substrate 1 resets, the locking hook 3 falls into the lock hole 5 under the action of gravity, and the electric moving contact 82 is accordingly lapped on the electric static contact 81. During the actual installation and debugging process, since the door ball group 7 is installed on the substrate 1 through the first connecting plate 6, after the staff completes the installation of the electric switch 8 and the substrate 1, only the position of the first connecting plate 6 relative to the substrate 1 needs to be adjusted and installed, and the position of the door ball group 7 can be independently debugged, reducing the project volume.
