Technical Field

[0001] The present application relates to the technical field of civil air defense doors, and in particular to a new type of earthquake-resistant civil air defense door. Background Art

[0002] Civil defense doors are doors at the entrances and exits of people's defense projects. They are mainly used in public places, commercial buildings, residential areas, hotels, schools, hospitals, underground transportation stations and large public buildings to provide safe isolation and protection for personnel and ensure the safety of life and property.

[0003] An earthquake-resistant civil air defense door mentioned in an existing Chinese public patent (authorization announcement number: CN215720486U) includes a wall, a civil air defense door arranged on the wall, a rotating part arranged on the civil air defense door, a buffer mechanism arranged on the wall and a cooling mechanism arranged on the civil air defense door; the cooling mechanism includes a water inlet, a water outlet arranged on the civil air defense door, a water inlet pipe arranged on the civil air defense door, a water outlet pipe arranged on the civil air defense door, a dustproof component arranged on the civil air defense door, a first flow limiting component arranged on the water inlet pipe and a second flow limiting component arranged on the civil air defense door; the dustproof component includes a dustproof plate, a dust plug component arranged on the dustproof plate, a dustproof slide groove arranged on the civil air defense door, a baffle arranged on the civil air defense door, a baffle slide groove arranged on the civil air defense door, a baffle spring arranged on the baffle and a fixing component arranged on the civil air defense door.

[0004] In the above patent, by passing cold water into the water inlet pipe, the heat of the civil air defense door can be effectively dissipated to prevent the civil air defense door from aging due to high temperature. However, in actual use, when natural disasters such as earthquakes occur, the civil air defense door is prone to cracks or even collapse under the action of seismic force, and cannot effectively resist the damage caused by the earthquake. For this reason, the present application provides a new type of earthquake-resistant civil air defense door. Utility Model Content

[0005] The purpose of this application is to solve the problem that when natural disasters such as earthquakes occur, civil air defense doors are easily cracked or even collapsed under the action of earthquake forces and cannot effectively resist the damage caused by earthquakes. This application provides a new type of earthquake-resistant civil air defense door.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A new type of earthquake-resistant civil defense door includes a wall, a door frame is fixedly connected to the inside of the wall, a door leaf is hinged to the inside of the door frame, two hinges are symmetrically fixedly connected to one side of the door leaf, a rotating handle is provided on one side of the door leaf, a plurality of earthquake-resistant components are installed inside the door leaf, a cavity is opened at the bottom of the door leaf, and auxiliary components are installed inside the cavity.

[0008] By adopting the above technical solution, when one end of the door leaf rotates away from the door frame, the door leaf will be in a suspended state. At this time, the auxiliary component can be rotated to operate, extend the auxiliary component from the cavity and fit it to the ground. The auxiliary component can assist the door leaf to open, making it more convenient and quick to open the door leaf. At the same time, the support of the auxiliary component can also relieve the pressure on the hinge connection, effectively improving the service life of the door leaf. Secondly, when natural disasters such as earthquakes occur, the support and buffering of multiple seismic components inside the door leaf can effectively slow down the seismic force received by the door leaf, thereby improving the overall seismic resistance of the door leaf.

[0009] Furthermore, the seismic anti-vibration component includes two fixed blocks 1 symmetrically fixedly connected on one side of the interior of the door leaf, and two fixed blocks 2 symmetrically fixedly connected on the other side of the interior of the door leaf, one side of the two fixed blocks 1 is hinged with a rotating column 1, one side of the two fixed blocks 2 is hinged with a rotating column 2, one end of the rotating column 1 away from the fixed block 1 is hinged with an adjusting block, one end of the rotating column 2 away from the fixed block 2 is hinged to the adjusting block, and one end of the two adjusting blocks away from the hinge interface is slidably connected with a support block.

[0010] By adopting the above technical solution, when the fixed block 1 and the fixed block 2 are vibrated, the force they receive will be transmitted to the rotating column 1 and the rotating column 2, so that the rotating column 1 and the rotating column 2 will rotate slightly. When the rotating column 1 and the rotating column 2 rotate slightly, the two adjustment blocks will be squeezed close to each other inside the supporting block.

[0011] Furthermore, a shock absorbing spring is fixedly connected inside the support block, and two ends of the shock absorbing spring are respectively fixedly connected to one end of the two adjustment blocks.

[0012] By adopting the above technical solution, when the rotating column 1 and the rotating column 2 rotate slightly, the two adjustment blocks are squeezed closer to each other inside the supporting block, thereby squeezing the shock-absorbing spring inside the supporting block to shrink.

[0013] Furthermore, a plurality of dampers are evenly and fixedly connected inside the door leaf.

[0014] By adopting the above technical solution, the vibration of the door leaf can be effectively buffered and alleviated through the cooperation between the shock-absorbing spring and the damper.

[0015] Furthermore, the auxiliary component includes a support plate fixedly connected to one side of the cavity, the top of the support plate is rotatably connected to a screw rod, a T-shaped block is threadedly connected to the screw rod, an auxiliary wheel is fixedly connected to the bottom of the T-shaped block, and a driving member is installed on the screw rod.

[0016] By adopting the above technical solution, the auxiliary wheels can assist the door leaf to open better, effectively saving the force of opening the door. At the same time, the support of the auxiliary wheels can also relieve the pressure on the hinge connection, effectively improving the service life of the door leaf.

[0017] Furthermore, the driving member includes a bevel gear 1 fixedly connected to the screw rod, one side of the door leaf is rotatably connected to a rotating rod, one end of the rotating rod is fixedly connected to a rotating handle 2, the other end of the rotating rod is fixedly connected to a bevel gear 2, and the bevel gear 2 is meshingly connected to the bevel gear 1.

[0018] By adopting the above technical solution, since bevel gear 2 and bevel gear 1 are meshed with each other, when bevel gear 2 rotates, bevel gear 1 will be driven to rotate together, so that the screw rod starts to rotate, and the T-shaped block can gradually descend on the screw rod according to the rotation of the screw rod.

[0019] Furthermore, a sound insulation layer is fixedly connected to one side of the door leaf.

[0020] By adopting the above technical solution, the overall sound insulation effect of the door leaf can be improved through the sound insulation layer.

[0021] Furthermore, the surface of the door leaf is covered with a fireproof layer.

[0022] By adopting the above technical solution, the fireproofing layer can increase the overall fireproofing effect of the door leaf.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. The present application is provided with earthquake-resistant components and dampers. When natural disasters such as earthquakes occur, the door leaf will vibrate due to the earthquake force. Through the cooperation between the shock-absorbing spring and the damper, the vibration of the door leaf can be effectively buffered and alleviated, thereby protecting the door leaf as a whole, reducing the risk of cracks or even collapse of the civil air defense door, and effectively resisting the damage caused by the earthquake.

[0025] 2. The present application is provided with an auxiliary component. Since the civil air defense door is heavy and difficult to open, when one end of the door leaf rotates away from the door frame, the door leaf will be in a suspended state. At this time, the auxiliary component can be rotated to extend the auxiliary component from the cavity and fit it to the ground. The auxiliary component can assist in opening the door leaf, making it more convenient and quick to open the door leaf. At the same time, the support of the auxiliary component can also relieve the pressure on the hinge connection, effectively improving the service life of the door leaf.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiments of the present application disclose a new type of earthquake-resistant civil defense door.

[0034] Reference Figure 1 and Figure 2 The new earthquake-resistant civil air defense door comprises a wall 1, a door frame 2 is fixedly connected to the inside of the wall 1, a door leaf 3 is hingedly connected to the inside of the door frame 2, two hinges 4 are symmetrically fixedly connected to one side of the door leaf 3, a rotating handle 5 is provided on one side of the door leaf 3, a plurality of earthquake-resistant components 6 are installed inside the door leaf 3, a cavity is opened at the bottom of the door leaf 3, and an auxiliary component 8 is installed inside the cavity.

[0035] When in use, first turn the rotating handle 5 to pull the door leaf 3 to rotate. When one end of the door leaf 3 rotates away from the door frame 2, the door leaf 3 will be in a suspended state. At this time, in order to reduce the pressure on the connection of the hinge 4, the auxiliary component 8 can be rotated to operate, and the auxiliary component 8 can be extended from the cavity and fit into the ground. The auxiliary component 8 can assist the door leaf 3 to open, and the door leaf 3 can be opened more conveniently and quickly. At the same time, the support of the auxiliary component 8 can also relieve the pressure on the connection of the hinge 4, effectively improving the service life of the door leaf 3. When the door leaf 3 needs to be closed, the auxiliary component 8 can be operated again to retract the auxiliary component 8 into the cavity to avoid affecting the normal closing of the door leaf 3. Secondly, when natural disasters such as earthquakes occur, the support and buffering of multiple seismic resistant components 6 inside the door leaf 3 can effectively slow down the seismic force received by the door leaf 3, thereby improving the overall seismic resistant effect of the door leaf 3.

[0036] Reference Figure 1, Figure 2 and Figure 3 The anti-seismic component 6 includes two fixed blocks 61 symmetrically fixedly connected to one side of the interior of the door leaf 3, and two fixed blocks 62 symmetrically fixedly connected to the other side of the interior of the door leaf 3. One side of the two fixed blocks 61 is hinged with a rotating column 63, and one side of the two fixed blocks 62 is hinged with a rotating column 64. The end of the rotating column 63 away from the fixed block 61 is hinged with an adjusting block 65, and the end of the rotating column 64 away from the fixed block 62 is hinged to the adjusting block 65. The ends of the two adjusting blocks 65 away from the hinge interface are slidably connected with a supporting block 66, and a shock-absorbing spring 67 is fixedly connected inside the supporting block 66. The two ends of the shock-absorbing spring 67 are respectively fixedly connected to one end of the two adjusting blocks 65, and a plurality of dampers 7 are evenly fixedly connected inside the door leaf 3.

[0037] When a natural disaster such as an earthquake occurs, the door leaf 3 will vibrate due to the earthquake force. At this time, the vibration force will be transmitted to the multiple dampers 7 inside the door leaf 3, and the internal fixed block 1 61 and fixed block 2 62 will also be vibrated. When the fixed block 1 61 and fixed block 2 62 are vibrated, the force they receive will be transmitted to the rotating column 1 63 and rotating column 2 64, so that the rotating column 1 63 and rotating column 2 64 will rotate slightly. When the rotating column 1 63 and rotating column 2 64 rotate slightly, the two adjustment blocks 65 will be squeezed close to each other inside the support block 66, thereby squeezing the shock-absorbing spring 67 inside the support block 66 to contract. Through the mutual cooperation between the shock-absorbing spring 67 and the damper 7, the vibration received by the door leaf 3 can be effectively buffered and alleviated, thereby protecting the door leaf 3 as a whole, reducing the risk of cracks or even collapse of the civil air defense door, and effectively resisting damage caused by earthquakes.

[0038] Reference Figure 1 and Figure 4 The auxiliary component 8 includes a support plate 81 fixedly connected to one side of the cavity, a screw rod 82 is rotatably connected to the top of the support plate 81, a T-shaped block 83 is threadedly connected to the screw rod 82, an auxiliary wheel 84 is fixedly connected to the bottom of the T-shaped block 83, a driving member is installed on the screw rod 82, the driving member includes a bevel gear 1 85 fixedly connected to the screw rod 82, a rotating rod 86 is rotatably connected to one side of the door leaf 3, one end of the rotating rod 86 is fixedly connected to a rotating handle 2 87, and the other end of the rotating rod 86 is fixedly connected to a bevel gear 2 88, and the bevel gear 2 88 is meshingly connected with the bevel gear 1 85.

[0039] When the door leaf 3 needs to be closed later, the rotating handle 2 87 can be turned in the opposite direction to drive the T-shaped block 83 and the auxiliary wheel 84 to be retracted into the cavity to avoid affecting the closing of the door leaf 3.

[0040] Reference Figure 1 and Figure 2 A sound insulation layer 9 is fixedly connected to one side of the door leaf 3 , and a fireproof layer 10 is covered on the surface of the door leaf 3 .

[0041] When in use, the sound insulation layer 9 can improve the overall sound insulation effect of the door leaf 3 , and the fireproof layer 10 can increase the overall fireproof effect of the door leaf 3 .

[0042] The implementation principle of the new earthquake-resistant civil air defense door of this embodiment is as follows: when in use, first turn the rotary handle 1 5 to pull the door leaf 3 to rotate. When one end of the door leaf 3 rotates away from the door frame 2, the door leaf 3 will be in a suspended state. At this time, in order to reduce the pressure on the connection of the hinge 4, the rotary handle 2 87 can be turned to drive the rotating rod 86 to rotate. When the rotating rod 86 rotates, it will drive the bevel gear 2 88 to rotate together. Because the bevel gear 2 88 and the bevel gear 1 85 are meshed with each other, when the bevel gear 2 88 rotates, it will drive the bevel gear 1 85 to rotate together, so that the screw rod 82 starts to rotate. The rotation of the screw rod 82 can make the T-shaped block 83 gradually descend on the screw rod 82, thereby driving the auxiliary wheel 84 at the bottom to extend from the cavity until the auxiliary wheel 84 is in contact with the ground. The auxiliary wheel 84 can assist the door leaf 3 to open better, effectively saving the force of opening the door. At the same time, the support of the auxiliary wheel 84 can also relieve the pressure on the connection of the hinge 4, effectively improving the service life of the door leaf 3. When the door leaf 3 needs to be closed later, the second rotating handle 87 can be rotated in the opposite direction to drive the T-shaped block 83 and the auxiliary wheel 84 to re-enter the cavity to avoid affecting the closing of the door leaf 3.

[0043] Secondly, when natural disasters such as earthquakes occur, the door leaf 3 will vibrate due to the earthquake force. At this time, the vibration force will be transmitted to the multiple dampers 7 inside the door leaf 3, and the internal fixed block 1 61 and fixed block 2 62 will also be vibrated. When the fixed block 1 61 and the fixed block 2 62 are vibrated, the force they receive will be transmitted to the rotating column 1 63 and the rotating column 2 64, so that the rotating column 1 63 and the rotating column 2 64 will rotate slightly. When the rotating column 1 63 and the rotating column 2 64 rotate slightly, the two adjustment blocks 65 will be squeezed close to each other inside the support block 66, thereby squeezing the shock-absorbing spring 67 inside the support block 66 to contract. Through the mutual cooperation between the shock-absorbing spring 67 and the damper 7, the vibration received by the door leaf 3 can be effectively buffered and alleviated, thereby protecting the door leaf 3 as a whole, reducing the risk of cracks or even collapse of the civil air defense door, and effectively resisting damage caused by earthquakes.
