Abstract
This application discloses a door limiting structure, relating to the technical field of door limiting, including a pull rod, a mounting plate, a limiting plate, and a driving component. The mounting plate is fixedly mounted on the door. One end of the pull rod is rotatably mounted on the door body, and the other end is provided with a limited portion. The limited portion is slidably connected to the mounting plate along its length. The limiting plate is slidably connected to the mounting plate, and the limiting plate is provided with at least two slots spaced apart. The limited portion can be engaged by any slot to lock its position relative to the mounting plate. The driving component can drive the limiting plate to move so that the slots can enter or exit the sliding path of the limited portion, thereby locking or unlocking the position of the limited portion relative to the mounting plate. In this application, by engaging the limited portion with slots at different positions, the angle of door limiting can be changed, thus adapting to various working conditions.
