DETAILED DESCRIPTION

[0021] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a civil air defense door with a protective structure, comprising a door frame 1, a hinge block 2 hinged inside the door frame 1, a civil air defense door 3 fixedly installed on the hinge block 2, a handle 4 is provided on the civil air defense door 3, a protective plate 5 is provided on the outer side of the civil air defense door 3, a protective mechanism 6 is provided inside the civil air defense door 3, and a reset mechanism 7 is provided on the civil air defense door 3 and the door frame 1.

[0022] In this embodiment, a protective mechanism 6 is provided inside the civil defense door 3. When the protective plate 5 is impacted, the slider 62 in the protective mechanism 6 compresses the reset spring 63 to move in the direction of the slot 73. The impact force can be converted into the elastic potential energy of the reset spring 63, thereby preventing the civil defense door 3 from being damaged by a large impact force.

[0023] In this embodiment, a reset mechanism 7 is provided on the civil defense door 3 and the door frame 1. The block 72 in the reset mechanism 7 is engaged with the inside of the slot 73, which can prevent the rebound of the protective plate 5 from causing a secondary impact. At the same time, the reset plate 74 moves into the inside of the slot 73 to squeeze the block 72 so that the limit is released, which can reset the protective plate 5 to facilitate the protection of the civil defense door 3 again.

[0024] The above-mentioned protective mechanism 6 includes a fixed rod 61, which is fixedly installed on the inner wall of the civil defense door 3. A slider 62 is slidably connected to the outer wall of the fixed rod 61. The slider 62 is slidably connected to the inner wall of the civil defense door 3. A reset spring 63 is sleeved on the outer wall of the fixed rod 61. One end of the reset spring 63 is fixedly connected to the inner wall of the civil defense door 3, and the other end of the reset spring 63 is fixedly connected to the side wall of the slider 62. By converting the impact force into the elastic potential energy of the reset spring 63, the civil defense door 3 can be prevented from being subjected to a large impact force. The slider 62 is hinged to one end of the support rod 64. The end of the support rod 64 is squeezed by the protective plate 5, so that the slider 62 can compress the reset spring 63 and move in the direction of the slot 73 to reduce the impact force. The other end of the support rod 64 is hinged to the outer wall of the protective plate 5.

[0025] The above-mentioned reset mechanism 7 includes an elastic plate 71, which is fixedly mounted on the outer wall of the slider 62. A clamping block 72 is fixedly mounted on the outer wall of the elastic plate 71, and the clamping block 72 is arranged in an arc shape. A clamping slot 73 is opened on the civil air defense door 3, and the clamping slot 73 is located on the side of the clamping block 72. The clamping block 72 is clamped in the inside of the clamping slot 73 through the elastic force of the elastic plate 71, which can prevent the rebound of the protective plate 5. A reset plate 74 is fixedly mounted on the outer wall of the door frame 1, and the reset plate 74 is arranged in an arc shape. The reset plate 74 moves into the inside of the clamping slot 73 to squeeze the clamping block 72 so that the limit is released, so that the protective plate 5 can be reset to facilitate the protection of the civil air defense door 3 again.

[0026] In this embodiment, when extrusion occurs, the protective plate 5 is squeezed to move inside the civil air defense door 3 to squeeze the end of the support rod 64. At this time, through the extrusion between the support rod 64 and the slider 62, the slider 62 compresses the reset spring 63 to move in the direction of the slot 73, and then the slider 62 drives the block 72 on the outer wall of the elastic plate 71 to move in the direction of the slot 73 and be squeezed. The arc surface of the block 72 is squeezed to drive the elastic plate 71 to release the limit, and finally the elastic force of the elastic plate 71 causes the block 72 to be connected to the slot 73. 3, preventing the rebound of the protective plate 5, and then protecting the civil defense door 3 from a large impact force by converting the impact force into the elastic potential energy of the reset spring 63. When the position of the protective plate 5 needs to be protected, when the civil defense door 3 is opened and closed, the reset plate 74 is moved into the slot 73 by the rotation of the civil defense door 3 to squeeze the block 72, thereby releasing the limit. The elastic force of the reset spring 63 is used to make the support rod 64 drive the protective plate 5 to reset, so as to facilitate the protection of the civil defense door 3 again.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
