Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an elevator top door device. Background Art

[0002] During the installation and maintenance of the elevator door area, it is often necessary to open the elevator floor door and keep it open for a period of time to perform various inspection operations. Under the action of the elevator car door machine or the floor door self-closing device, the elevator door will remain locked or closed under normal conditions. In order to keep the elevator door open continuously, the installation and maintenance personnel often use tools to insert into the gap between the elevator door sill and the lower part of the door to jam the elevator door and prevent the floor door or car door from closing. The most commonly used tool is a screwdriver. Although the screwdriver is readily available, the screwdriver rod is smooth and small, and the friction between the handle and the sill is insufficient, so it often slides and cannot effectively prevent the elevator door from closing. If the elevator door is kept open without using tools or other methods, it will interfere with the continuous operation of the installation and maintenance personnel, which will not only cause operational troubles and reduce work efficiency, but also pose a safety hazard. Utility Model Content

[0018] As a preferred solution of the present utility model, the magnetic component is located above the elastic component.

[0019] By adopting the above scheme, the magnetic part is located above the elastic part. When the magnetic part is attached to the elevator door, the elastic part of the elastic sheet can contact the elevator door. When the elevator door remains closed, the thrust of the elevator door can be transmitted to the embedded block from the magnetic part and the elastic part respectively, thereby further improving the firmness of the top door.

[0020] As a preferred solution of the utility model, the embedded block is a rubber block.
