Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5The utility model provides a technical solution: a protective door for civil air defense projects with a buffering function, comprising a door frame 1, a door panel 2 is hinged on one side of the door frame 1 through a hinge, a cavity is opened inside the door frame 1, a motor 3 is fixedly installed on the inner wall of the cavity, a sliding block 4 is slidably connected inside the cavity, a screw rod 5 is fixedly installed on the output shaft of the motor 3, and one end of the screw rod 5 passes through the sliding block 4 and extends to the outside of the sliding block 4.

[0027] The front surface of the sliding block 4 is rotatably connected to a connecting rod 6 through an axle seat. One end of the connecting rod 6 passes through the door frame 1 and extends to the outside of the door frame 1. A positioning block 7 is fixedly installed on one side of the door panel 2. A rotating rod 8 is inserted on the positioning block 7. The top of the rotating rod 8 passes through the connecting rod 6 and extends to the outside of the connecting rod 6.

[0028] A groove is provided inside the door panel 2, a buffer spring 9 is fixedly installed on the inner wall of the groove, a buffer block 10 is fixedly installed on one end of the buffer spring 9, a buffer strip 11 is fixedly installed on one side of the buffer block 10, and one side of the buffer strip 11 passes through the door panel 2 and extends to the outside of the door panel 2.

[0029] See also Figure 3 A thread hole for the screw rod 5 to pass through is opened on the sliding block 4, and the thread hole is threadedly connected to the screw rod 5. One end of the screw rod 5 is sleeved with a sleeve, and the sleeve is rotatably connected to the screw rod 5. One end of the sleeve is fixedly connected to one side of the inner wall of the cavity on the door frame 1.

[0030] The set thread hole is threadedly connected to the screw rod 5. During use, when the screw rod 5 rotates, it is convenient to rotate the screw rod 5 so that the screw rod 5 drives the sliding block 4 to move left or right. At the same time, the setting of the sleeve facilitates the positioning operation of the screw rod 5 and facilitates the subsequent rotation of the screw rod 5.

[0031] See also Figure 3 The sliding block 4 is adapted to the cavity, and the upper surface and the lower surface of the sliding block 4 are slidably connected to the inner top wall and the inner bottom wall of the cavity of the door frame 1 respectively.

[0032] The sliding block 4 is slidably connected to the inner wall of the cavity on the door frame 1, which facilitates the normal movement of the sliding block 4 during use, thereby facilitating the normal operation of subsequent components.

[0033] See also Figure 1 , Figure 2 The top of the rotating rod 8 is threadedly connected with a screw tube 12, the bottom of the screw tube 12 contacts the upper surface of the connecting rod 6, and a round hole for the rotating rod 8 to rotate is opened on the connecting rod 6, and the rotating rod 8 can slide up and down in the round hole on the connecting rod 6.

[0040] The setting of the through groove facilitates the passage of the subsequent buffer strip 11, and facilitates the buffer strip 11 to enter and extend out of the door panel 2 during the subsequent door opening and closing process, thereby facilitating subsequent use.

[0041] See also Figure 1 , Figure 2 The bottom of the door frame 1 is open, and a protective plate 15 is arranged inside the door frame 1. A conical nail 16 is fixedly installed at the bottom of the protective plate 15. Screws 17 are threadedly connected on both sides of the door frame 1.

[0042] The protective plate 15 is provided to facilitate supporting and protecting operations during use, and is also convenient for subsequent installation to raise its height above the ground to form a bulge, thereby achieving a water blocking effect.

[0043] During operation, the motor 3 is controlled to work, and then the motor 3 drives the screw rod 5 to rotate, so that the screw rod 5 drives the sliding block 4 to move on the screw rod 5, thereby driving the rotating rod 8 on the connecting rod 6 to move, and the connecting rod 6 rotates on the rotating rod 8 while pulling the door panel 2 to move.

[0044] The buffer spring 9 performs a buffering operation on the buffer block 10 , so that the buffer block 10 performs a buffering operation on the buffer strip 11 . When the door panel 2 overlaps with the door frame 1 , one side of the buffer strip 11 contacts the inner side of the door frame 1 .

[0045] In summary, the device can close or open the door. In the subsequent use process, it avoids manual opening and closing of the door, reduces manpower expenditure, facilitates the operation of subsequent users, increases the difficulty of opening and closing the door, saves manpower, facilitates buffering of the door panel 2, and also facilitates squeezing between the door panel 2 and the door frame 1, thereby increasing the sealing of the protective door and facilitating subsequent use.
