Description

Technical Field

[0001] This application relates to the field of civil defense door technology, and more specifically, to an insulated explosion-proof safety civil defense door. Background Technology

[0002] Explosion-proof doors are explosion-proof protective devices designed to withstand accidental explosions of external equipment in industrial buildings, ensuring the safety of personnel and the integrity of internal equipment, protecting them from the blast wave and effectively preventing the continuation of the explosion's harmful effects. They are typically made of special industrial steel plates according to strictly defined mechanical data and equipped with high-performance hardware to safeguard life and property.

[0003] Currently, patent document CN203685292U discloses an explosion-proof door, including a door body and a door frame. The door body is connected to the door frame via hinges, and the sealing strips of the door body and the door frame are tightly fitted. A locking device compresses the sealing strips through the door body. The locking device includes a main shaft with handwheels at both ends. The main shaft has a drive gear, and the lower end of the drive gear intersects with and is connected to a driven gear via a pin. Two secondary connecting rods are provided on both sides of the drive gear, and three tertiary connecting rods are provided above and below it. One end of the upper and lower tertiary connecting rods is connected to the secondary connecting rods via a pin, and the other end is connected to a rocker arm. Three rocker arms are connected to the two secondary connecting rods on both sides. The rocker arms are fixed to locking claws on the door panel via a rotating shaft. The driven gear is connected to the two secondary connecting rods on both sides via two primary connecting rods. The door frame has a locking cavity that locks with the locking claws. The above-mentioned explosion-proof door improves the explosion-proof performance and safety function, not only eliminating the safety hazards of explosion-proof doors, but also having a simple structure and being safe and reliable.

[0027] Reference Figure 1-6 An insulated explosion-proof safety air-raid shelter door 100 includes: 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 101a extending along the width direction of the first door panel 101, and the second door panel 102 moves along the guide groove 101a. Insulating pads are provided around the first door panel 101 to increase the insulation of the air-raid shelter door.

[0028] 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 groove 102a extending along the length of the second door panel 102, and the first slider 103 moves along the first groove 102a. The two ends of the first spring 104 are fixedly connected to the first slider 103 and the second door panel 102, respectively. 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 fixedly connected to the first door panel 101 and the second door panel 102, respectively.

[0029] The adjusting component, used to adjust the position of the damping block 106, includes: a guide post 108, a connecting plate 109, and a driving block 110. The guide post 108 is fixedly connected to the first door panel 101. The connecting plate 109 is horizontally slidably connected to the guide post 108. Specifically, the upper end of the connecting plate 109 is provided with a guide sleeve 109a, and part of the guide post 108 is located within the guide sleeve 109a for guiding 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 sliding groove 109b extending along the length of the connecting plate 109, and the driving block 110 moves along the second sliding 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.

[0030] The damping blocks 106 are arranged in two sets, upper and lower, with two damping blocks 106 in each set, symmetrically arranged. An adjusting component is used to simultaneously adjust both sets of damping blocks 106. The transmission blocks 105 are also arranged in two sets, upper and lower, corresponding to the damping blocks 106, with two transmission blocks 105 in each set, symmetrically arranged. The drive assembly drives the connecting plate 109 to move. The connecting plate 109 is guided by the guide post 108. The movement of the connecting plate 109 drives the drive block 110 to move. When the first inclined surface 110a of the drive block 110 abuts against the transmission inclined surface 105a of one side of the transmission block 105, the drive block 110 moves along the second slide groove 109b, causing the second inclined surface 110b of the drive block 110 to abut against the transmission inclined surface 105a of the other side of the transmission block 105. Then, the connecting plate 109 continues to move, and the transmission block 105 moves along the second slide groove 109b. A first slider 103 is provided, which moves along the first slide groove 102a. Therefore, through the first inclined surface 110a of the drive 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. Through the second inclined surface 110b of the drive 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 blocks 106.

[0031] The drive assembly, used to drive the adjustment component to move, includes: a guide block 112, a screw 113, a third slider 114, and a handwheel 115. The guide block 112 is fixedly connected to the first door panel 101. The screw 113 is rotatably connected to the second door panel 102. The third slider 114 is horizontally slidably connected to the guide block 112, and its interior is threadedly connected to the screw 113. Specifically, the guide block 112 has a third groove 112a extending in its width direction. The third slider 114 is partially located within the third groove 112a and moves along it. The third slider 114 is fixedly connected to the connecting plate 109. Rotating the handwheel 115 causes the screw 113 to rotate, and the third slider 114 moves along the third groove 112a. Therefore, the rotation of the screw 113 causes the third slider 114 to move, which in turn causes the connecting plate 109 to move, thereby moving the adjustment component.

[0032] 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 wears, the handwheel 115 is turned. The rotation of the handwheel 115 drives the screw 113 to rotate, and the third slider 114 moves along the third slide groove 112a. Therefore, the rotation of the screw 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 post 108. The movement of the connecting plate 109 drives the drive block 110 to move. When the first inclined surface 110a of the drive block 110 abuts against the transmission inclined surface 105a of one side of the transmission block 105, the drive block 110 will move along the second slide groove 109b, so that the second inclined surface 110b of the drive block 110 abuts against the transmission inclined surface 105a of the other side of the transmission block 105. Then the connecting plate 109 continues to move. The transmission block 105 has a first slider 103 on one side. The first slider 103 moves along the first slide groove 102a. Therefore, through the first inclined surface 110a of the drive 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. Through the second inclined surface 110b of the drive block 110 and the transmission inclined surface 105a of the other transmission block 105, the other transmission block 105 will be driven to move. This simultaneously drives the two damping blocks 106 to move relative to each other, so that the two damping blocks 106 are adjusted to a suitable position. The damping blocks 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.
