[0001] The utility model relates to the technical field of elevator cars, in particular to an upward opening structure of the top of an elevator car. Background Art

[0002] The car is a box-shaped space used by the elevator to carry and transport people and materials. The car is generally composed of the car bottom, car wall, car top, car door and other main parts. It is the car body part used by the elevator to carry passengers or goods and other loads. The ceiling is usually made of mirror stainless steel; the car bottom is 2mm thick PVC marble pattern or 20mm thick marble mosaic.

[0003] The upward opening structure of the existing elevator car top is to rotate the car top and install it on the inner end of the car during use. When opening, the staff needs to manually apply thrust to the car top to overcome the weight of the car top to push it and flip it, thereby opening the top of the car. During operation, the above method not only requires the staff to use auxiliary stools or ladders, but also increases the staff's fatigue by lifting with both hands, which makes the operation process of the opening structure more cumbersome and affects its use effect. Therefore, there is an urgent need for an upward opening structure of the elevator car top to solve the above problems. Utility Model Content
