[0034] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0035] Reference Figure 1-6, an insulated explosion-proof safety civil air defense door 100, comprising: a first door panel 101, a second door panel 102, a first slider 103, a first spring 104, a transmission block 105, a damping block 106, a second spring 107, an adjusting member for adjusting the damping block 106, and a driving assembly for driving the adjusting member. The second door panel 102 is horizontally slidably connected to the first door panel 101. Specifically, the first door panel 101 is provided with a guide groove 101 extending along the width direction of the first door panel 101, and the second door panel 102 moves along the guide groove 101. Insulating pads are arranged around the first door panel 101 to increase the insulation of the civil air defense door.

[0036] The first slider 103 is horizontally slidably connected to the second door panel 102. Specifically, the second door panel 102 is provided with a first slide groove 102a extending along the length direction of the second door panel 102, and the first slider 103 moves along the first slide groove 102a. The two ends of the first spring 104 are respectively fixedly connected to the first slider 103 and the second door panel 102. The transmission block 105 is fixedly connected to the first slider 103. The damping block 106 is fixedly connected to the transmission block 105. The two ends of the second spring 107 are respectively fixedly connected to the first door panel 101 and the second door panel 102.

[0037] The adjusting member is used to adjust the position of the damping block 106, and includes: a guide column 108, a connecting plate 109, and a driving block 110. The guide column 108 is fixedly connected to the first door panel 101. The connecting plate 109 is horizontally slidably connected to the guide column 108. Specifically, a guide sleeve 109a is provided at the upper end of the connecting plate 109, and the guide column 108 is partially located in the guide sleeve 109a, which is used to guide the guide sleeve 109a. The driving block 110 is horizontally slidably connected to the connecting plate 109. Specifically, the connecting plate 109 is provided with a second slide groove 109b extending along the length direction of the connecting plate 109, and the driving block 110 moves along the second slide groove 109b. The driving block 110 is provided with a first inclined surface 110a and a second inclined surface 110b, and the transmission block 105 is provided with a transmission inclined surface 105a, the first inclined surface 110a is used to drive one transmission block 105, and the second inclined surface 110b is used to drive another transmission block 105.

[0038] Among them, the damping blocks 106 are provided in two groups, upper and lower, each group of damping blocks 106 is provided with two, and the two damping blocks 106 are symmetrically arranged. The adjusting member is used to adjust the two groups of damping blocks 106 at the same time. The transmission blocks 105 are provided with two groups, upper and lower, corresponding to the damping blocks 106, each group of transmission blocks 105 is provided with two; the two transmission blocks 105 are symmetrically arranged. The driving assembly drives the connecting plate 109 to move, and the connecting plate 109 is guided by the guide column 108. The movement of the connecting plate 109 drives the driving block 110 to move. When the first inclined surface 110a of the driving block 110 abuts against the transmission inclined surface 105a of the transmission block 105 on one side, the driving block 110 will move along the second slide groove 109b, so that the second inclined surface 110b of the driving block 110 abuts against the transmission inclined surface 105a of the transmission block 105 on the other side, and then the connecting plate 109 continues to move, and one side of the transmission block 105 A first slider 103 is provided, and the first slider 103 moves along the first slide groove 102a. Therefore, through the first inclined surface 110a of the driving block 110 and the transmission inclined surface 105a of one of the transmission blocks 105, one of the transmission blocks 105 will be driven to move, and through the second inclined surface 110b of the driving block 110 and the transmission inclined surface 105a of the other transmission block 105, the other transmission block 105 will be driven to move, thereby driving the two damping blocks 106 to move relative to each other, thereby adjusting the position of the damping block 106.

[0039] The driving assembly is used to drive the adjustment member to move, and includes: a guide block 112, a screw rod 113, a third slider 114, and a hand wheel 115. The guide block 112 is fixedly connected to the first door panel 101. The screw rod 113 is rotationally connected to the second door panel 102. The third slider 114 is horizontally slidably connected to the guide block 112, and the interior of the third slider 114 is threadedly connected to the screw rod 113. Specifically, the guide block 112 is provided with a third slide groove 112a extending in the width direction of the guide block 112, and the third slider 114 is partially located in the third slide groove 112a and moves along the third slide groove 112a. The third slider 114 is fixedly connected to the connecting plate 109. When the hand wheel 115 is turned, the hand wheel 115 rotates to drive the screw rod 113 to rotate, and the third slider 114 moves along the third slide groove 112a, so the rotation of the screw rod 113 drives the third slider 114 to move, and the movement of the third slider 114 drives the connecting plate 109 to move, thereby driving the adjustment member to move.

[0040] Working process: The shock wave of the explosion is reduced by the damping block 106 and the second spring 107. When the damping block 106 is worn, the hand wheel 115 is turned. The rotation of the hand wheel 115 drives the screw rod 113 to rotate, and the third slider 114 moves along the third slide groove 112a. Therefore, the rotation of the screw rod 113 drives the third slider 114 to move. The movement of the third slider 114 drives the connecting plate 109 to move. The connecting plate 109 is guided by the guide column 108. The movement of the connecting plate 109 drives the driving block 110 to move. When the first inclined surface 110a of the driving block 110 abuts against the transmission inclined surface 105a of the transmission block 105 on one side, the driving block 110 is moved along the second slide groove 109b, so that the second inclined surface 110b of the driving block 110 abuts against the transmission inclined surface 105a of the transmission block 105 on the other side. , and then the connecting plate 109 continues to move, and a first slider 103 is provided on one side of the transmission block 105, and the first slider 103 moves along the first slide groove 102a. Therefore, through the first inclined surface 110a of the driving block 110 and the transmission inclined surface 105a of one of the transmission blocks 105, one of the transmission blocks 105 will be driven to move, and through the second inclined surface 110b of the driving block 110 and the transmission inclined surface 105a of the other transmission block 105, the other transmission block 105 will be driven to move, thereby simultaneously driving the two damping blocks 106 to move relative to each other, so that the two damping blocks 106 are adjusted to a suitable position, and the damping block 106 and the second spring 107 can better buffer the shock wave of the explosion, prevent the two damping blocks 106 from being adjusted to inconsistent positions, and increase the protection of the second door panel 102.
