Technical Field

[0001] This application relates to the technical field of civil air defense doors, especially safe and efficient civil air defense doors. Background Art

[0002] With the acceleration of the urbanization process and the improvement of social safety awareness, civil air defense projects, as important facilities for protecting people's lives and property, have also seen continuous progress in their design and manufacturing technologies. As a key component of civil air defense projects, the performance and quality of safe and efficient civil air defense doors directly affect the safety and operating efficiency of the entire project.

[0003] Civil air defense doors, as important entrances and exits of civil air defense projects, both their design and functions carry the heavy responsibility of protecting people's lives and property. While pursuing the convenience of personnel passage, such doors must also possess multiple safety features such as resistance to explosion shock, fire prevention, and anti-theft. Therefore, traditional civil air defense door designs often tend to use thick and heavy materials and structures to ensure their durability and effectively respond to various potential safety threats.

[0004] However, although thick and heavy materials ensure excellent protective performance of civil air defense doors, their structures also bring problems that cannot be ignored. During actual use, this thick and heavy material undoubtedly increases the burden on the rotating shaft of the civil air defense door. The rotating shaft needs to bear greater pressure and friction. Under long-term operation, it may lead to increased wear, which in turn affects the normal opening and closing of the civil air defense door. Content of the Utility Model

[0005] The purpose of this application is: to solve the problem that the rotating shaft needs to bear greater pressure and friction, and under long-term operation, it may lead to increased wear, which in turn affects the normal opening and closing of the civil air defense door.

[0035] Among them, a support ball 10 is ball-jointed at the bottom of the driving rod 5, and one end of the support ball 10 forms a rolling contact with the inner wall of the guiding slide rail 4.

[0036] During use, first, start the driving motor 6 to drive the driving rod 5 to drive the driving gear 7 to rotate, and make the driving gear 7 mesh with the arc-shaped tooth ring 8. At the same time, make the driving gear 7 drive the driving rod 5 to move along the guiding direction of the arc-shaped tooth ring 8, and make the driving rod 5 drive the support ball 10 to form a rolling contact with the inner wall of the guiding slide rail 4, and drive one end of the protective door 3 to move along the guiding direction of the guiding slide rail 4. At the same time, drive the protective door 3 to rotate around the hinged end with the door frame 1, so as to facilitate the cooperation of the driving rod 5 and the guiding slide rail 4. When the protective door 3 rotates around the hinge axis, a support is formed for one end of the protective door 3, thereby effectively reducing the pressure and friction force borne by the hinged end of the protective door 3, improving the smoothness of opening and closing the protective door 3, and extending the service life of the device.

[0037] Refer to Figures 1-3 , an installation bin 11 is opened inside the protective door 3. Top outlets 12 are symmetrically opened on one side of the installation bin 11.
