Moreover, descriptions of features known in the art may be omitted for the sake of clarity and conciseness.

The features described herein may be embodied in different forms and should not be construed as limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many possible ways to implement the methods, devices, and/or systems described herein that will be apparent after understanding the disclosure of the present application.

Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on," "connected to," coupled to, "over," or "overlying" another element, it may be directly "on," "connected to," coupled to, "over," or "overlying" the other element, or one or more other elements may be present therebetween. In contrast, when an element is referred to as being "directly on," "directly connected to," directly coupled to, "directly over" or "directly overlying" another element, there may be no intervening elements present.

As used herein, the term "and/or" includes any one of the associated listed items and any combination of any two or more of the items.

Although terms such as "first", "second", and "third" may be used herein to describe various elements, components, regions, layers or sections, these elements, components, regions, layers or sections should not be limited by these terms. Rather, these terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section referred to in the examples described herein may be termed a second element, component, region, layer or section without departing from the teachings of the examples.

For ease of description, spatial relationship terms such as "above … …," "upper," "below … …," and "lower" may be used herein to describe one element's relationship to another element as illustrated in the figures.

In conclusion, the smart cooperation of the first locking assembly and the second locking assembly and the locking action of the first locking assembly and the second locking assembly are utilized respectively in the application, so that the connection tightness between the door member and the elevator door frame 100 is improved.

In this embodiment, the first locking members are preferably provided in two sets, and the two sets of first locking members are respectively located at upper and lower ends of the first side edge of the door member to ensure the stability of the connection of the first side edge of the door member with the door frame 100.

Specifically, taking the first locking assembly located at the upper end of the first side edge of the door member as an example, the first locking assembly is described in detail, and the first locking assembly includes a first sleeve 104, a second sleeve 107, a pin 105 and a clamping member 106; wherein the snap member 106 can be snapped onto the elevator door frame 100 and welded to the sidewall of the first sleeve 104; the second sleeve 107 is welded on the door frame 111, the first end of the pin shaft 105 is welded inside the second sleeve 107, and the second end of the pin shaft 105 extends out of the second sleeve 107 and is formed with a clamping portion.

When the first side edge of the door member is connected to the elevator door frame 100 by the first locking assembly, it is achieved by inserting the snap-in portion into the first sleeve 104; since the first sleeve 104 is fixed to the elevator door frame 100, the clamping portion is fixed to the door member through the second sleeve 107, that is, when the clamping portion is inserted into the first sleeve 104, the door member and the elevator door frame 100 can be firmly connected together.

In addition, the diameter of the clamping portion is smaller than that of the first sleeve 104, and the clamping portion can rotate in the first sleeve 104; that is, the door member can be opened or closed to the door frame 100 by the rotational action of the latch portion within the first sleeve 104. When the door member needs to be installed on the elevator door frame 100, the door member is firstly connected with the elevator door frame 100 vertically (the plane of the door member is vertical to the plane of the elevator door frame 100), and then the door member is rotated clockwise or counterclockwise to be buckled on the elevator door frame 100, so that the operation risk of an installer is reduced (in the installation process, if the door member is directly connected in a mode of being parallel to the elevator door frame 100, once the installer has a fault in inserting the clamping part into the first sleeve 104, the operation risk of the installer is greatly improved).
