[0023] The following is combined with Figure 1-6 The utility model is described in further detail.
[0024] The utility model embodiment discloses a high-strength honeycomb-type anti-shock wave human defense door, referring to Figure 1-2 , including a door frame 1, a door leaf 2 which is rotatably arranged in the door frame 1 and is hollow inside, a plurality of hinge seats 4 are fixedly arranged on one side of the door frame 1, the door leaf 2 is rotatably connected between the plurality of hinge seats 4, the door frame 1 and the door leaf 2 are connected via the hinge seats 4, and the door frame 1, the door leaf 2 and the hinge seats 4 constitute the existing civil air defense door.
[0025] Reference Figure 2 A multi-layer seal 3 is provided between the door frame 1 and the door leaf 2. The multi-layer seal 3 is composed of a plurality of sealing strips provided between the door frame 1 and the door leaf 2. Through the arrangement of a plurality of sealing strips, it can be ensured that under the action of a shock wave, if the sealing effect of a certain sealing strip deteriorates due to impact, several other sealing strips can continue to seal between the door frame 1 and the door leaf 2, so that the sealing performance of the civil air defense door is not affected after being subjected to the shock wave. The connection method between the door frame 1 and the door leaf 2 and the sealing strip is a public technology of the existing civil air defense door, which will not be elaborated here.
[0026] Reference Figure 2 A honeycomb structure 21 is fixedly provided inside the door leaf 2. The honeycomb structure 21 is composed of a number of steel plates welded together into a honeycomb shape. The honeycomb shape has compression resistance and excellent impact resistance and energy absorption properties. The honeycomb structure 21 can improve the impact resistance of the door leaf 2.
[0027] Reference Figure 2-3A number of high-strength reinforcement members 22 for improving the rigidity and local impact resistance of the door leaf 2 are fixed inside the door leaf 2. The high-strength reinforcement members 22 include a number of reinforcement plates 23 crisscrossedly arranged inside the honeycomb structure member 21. The number of reinforcement plates 23 are fixed in the honeycomb grooves of the honeycomb structure member 21, and both ends of the reinforcement plates 23 are fixed to the inner side walls of the door leaf 2, so that the reinforcement plates 23 can reinforce the honeycomb structure member 21 and the inside of the door leaf 2. The material of the reinforcement plates 23 is selected to be a high-strength, lightweight material, such as glass fiber reinforced plastic (GFRP) or carbon fiber reinforced plastic (CFRP), so as to improve the strength of the door leaf 2 and minimize the weight of the door leaf 2.
[0028] Reference Figure 1 and Figure 4 A lubrication mechanism is provided at the junction of the door frame 1 and the door leaf 2. The lubrication mechanism includes a plurality of lubrication boxes 5 fixedly arranged on one side of the door frame 1 and filled with lubricating oil, and a plurality of pressing blocks 51 fixedly arranged on one side of the door leaf 2 for pressing out the lubricating oil in the lubrication box 5 to lubricate the hinge seat 4 after the door leaf 2 rotates. An elastic diaphragm 52 is fixedly provided on one side of the lubrication box 5 for pressing the pressing block 51 after rotation. The elastic diaphragm 52 can be the diaphragm in the existing diaphragm pump, which has certain elasticity and waterproof effect. When the civil air defense door is opened, the rotating door leaf 2 will squeeze the elastic diaphragm 52 through the pressing block 51.
[0029] Reference Figure 4-6 A sponge 53 for absorbing oil is provided in the lubrication box 5. The sponge 53 is in contact with the elastic membrane 52. When the elastic membrane 52 is squeezed, it squeezes the sponge 53, so that the sponge 53 slowly spits out the absorbed lubricating oil.
[0030] Reference Figure 4-6 An oil pipe 54 is fixedly provided on one side of the top of the lubrication box 5 for delivering the lubricating oil in the lubrication box 5 to the hinge seat 4 when the pressure block 51 is squeezed. The expelled lubricating oil will flow from the top of the sponge 53 through the oil pipe 54 into the hinge seat 4 to lubricate the hinge seat 4.
[0031] Reference Figure 4-5 The threaded hole at the top of the inner wall of the lubrication box 5 is provided with a refueling bolt 55 through which people can add lubricating oil to the lubrication box 5. The refueling bolt 55 can block the threaded hole after being rotated to prevent the lubricating oil from flowing out of the threaded hole when the sponge 53 spits oil and causing waste.
[0032] The implementation principle of a high-strength honeycomb anti-shock wave civil defense door of the utility model embodiment is:
[0033] When in use, the honeycomb-shaped honeycomb structural member 21 can improve the impact resistance of the door leaf 2 and reduce the risk of damage to the door leaf 2 under the action of shock waves. The reinforcing plate 23 in the high-strength reinforcing member 22 can strengthen the honeycomb structural member 21 and the inside of the door leaf 2, thereby improving the structural strength of the door leaf 2 and effectively resisting strong shock waves.
[0034] When people open the civil air defense door, the rotating door leaf 2 will squeeze the elastic diaphragm 52 through the pressure block 51. After being squeezed, the elastic diaphragm 52 will squeeze the sponge 53, so that the sponge 53 will slowly spit out the absorbed lubricating oil. The spitted lubricating oil will flow from the top of the sponge 53 through the oil pipe 54 to the hinge seat 4 to lubricate the hinge seat 4 at the junction of the door frame 1 and the door leaf 2. The lubrication of the junction between the door frame 1 and the door leaf 2 will help people to open and close the door leaf 2.
