Description

Guide limiting moving structure of arc door Technical Field The utility model belongs to the technical field of arc doors, and relates to a guide limiting moving structure of an arc door. Background The existing arc door has some disadvantages in terms of moving efficiency and moving stability. When the arc door is opened and closed, it is required to move along a specific arc track due to its structural characteristics, which results in a longer moving path than the linear door, thereby reducing moving efficiency. During the movement of the arc door, the unstable phenomenon of the door body can be caused at certain positions due to the change of the gravity center position of the arc door, and the main reasons for the occurrence of the defects are that the movement track and the structural design of the arc door must follow a circular arc fixed path, which limits the flexibility and the stability of the movement of the arc door. Conventional countermeasures include adding weight to the door body, using higher quality materials to increase the rigidity of the door body, and designing a more precise rail system to ensure smooth movement of the door body along a predetermined trajectory. However, these methods also have drawbacks. The addition of the counterweight can improve stability, but at the same time, the total mass of the door body is increased, so that a stronger driving device is needed, which not only increases the cost, but also can further reduce the moving efficiency, and therefore, a circular arc door guiding limit moving structure is needed to solve the above problems.
