Description

Technical Field

[0001] The utility model belongs to the technical field of civil air defense doors, and particularly relates to an anti-slip track door device for people. Background Technique

[0002] A civil air defense door is a door required for air raid prevention, disaster resistance, and reducing the harm of disasters. It is widely used in air defense passages and basements. High requirements are imposed on the impact resistance and strength of civil air defense doors. In order to improve the opening and closing efficiency, a sliding track type civil air defense door has been designed to facilitate the opening and closing of civil air defense doors by people.

[0003] The existing anti-slip track door device for people is composed of components such as a steel door panel and a sliding track. The door panel can be quickly opened and closed through the sliding track and pulleys. However, it does not have a self-cleaning function for the sliding track. During use, due to the presence of gravel, debris, soil and other substances inside the sliding track, the resistance of the rollers at the bottom of the civil air defense door increases when moving, affecting the movement of the door panel and making it impossible for users to quickly and conveniently open and close the civil air defense door. Therefore, we provide an anti-slip track door device for people to solve the above problems. Summary of the Utility Model
