[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, in the following descriptions, well-known structures and technologies have been omitted to avoid unnecessary confusion regarding the concept of this utility model.

[0027] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] like Figures 1-5 The waterproof elevator landing door lock assembly shown includes a lock arm assembly 100, and a first roller body 110 and a second roller body 120 are provided in the middle of the mounting plate 101 of the lock arm assembly 100 via a connecting shaft 102.

[0029] The first roller body 110 includes a first bearing fixed on the connecting shaft 102 and a first roller disposed on the first bearing.

[0030] The second roller body 120 includes a second bearing fixed on the connecting shaft 102 and a second roller disposed on the second bearing.

[0031] Unlike existing technologies, the bearings and rollers on the first roller body 110 and the second roller body 120 of this invention are integrated. This reduces installation risks during installation and subsequent usage risks.

[0032] The front end of the locking arm assembly 100 is provided with a latch 140 via the locking arm 130.

[0033] The front end of the mounting plate 101 of the locking arm assembly 100 is provided with a contact block 150 via a contact block mounting base 103.

[0034] Specifically, the contact block mounting base 103 includes a first contact block mounting plate 1031 and a second contact block mounting plate 1032 connected together, with the end of the first contact block mounting plate 1031 disposed on the mounting plate 101.

[0035] The front end of the first contact block mounting plate 1031 is connected to the second contact block mounting plate 1032. The second contact block mounting plate 1032 extends downward and a contact block 150 is provided at its extended end.

[0036] This configuration allows the contact block 150 to extend downwards, which effectively improves the overall waterproof performance.

[0037] The switch assembly 200 includes a door lock switch 220 controlled by a movable switch 210, and the signal receiving contact 221 of the door lock switch 220 is disposed inside the waterproof housing 230.

[0038] The waterproof housing 230 is removable for cleaning and maintenance, and is made of insulation material with a flame retardant rating of V-0.

[0039] The contact block 150 contacts or disconnects from the signal receiving contact 221 of the door lock switch 220, and the contact position is located on the inner side of the waterproof cover 230.

[0040] The switch assembly 200 is provided with a limiting groove 240 on the side facing the lock arm assembly 100, and the latch is locked 140 through the limiting groove 240.

[0041] To further reduce weight, the mounting plate 101 has a bend 104 only at the top.

[0042] The mounting plate 101 is provided with a plurality of oblong holes 1011, and the locking arm assembly 100 is installed on the external mounting plate (not shown) by the cooperation of the oblong holes 1011 and fasteners (not shown in the figure).

[0043] This invention is easy to install, effectively prevents the lock from slipping out of the lock groove, has a certain degree of waterproof safety performance, and has a long service life.

[0044] The above shows and describes the basic principles, main features, and advantages of this utility model.
