Description

Technical Field

[0001] The utility model relates to the technical field of civil air defense equipment, in particular to an anti-impact structure of civil air defense equipment. Background Art

[0002] The impact-proof structure of civil air defense equipment originates from the continuous attention and emphasis on the safety of personnel and property, as well as the recognition of threats such as natural disasters, terrorist attacks and accidents. With the continuous expansion of modern urbanization and the scale of construction, people have realized the vulnerability of buildings and underground facilities when they are hit by disasters such as earthquakes, explosions, and fires. Therefore, there is an urgent need to take effective measures to improve their resistance and safety. Against this background, the impact-proof structure of civil air defense equipment came into being. It is used to absorb and disperse energy when facing external shocks or vibrations, and reduce the impact of shocks on buildings or facilities.

[0003] The main structures of the existing anti-impact structures of civil air defense equipment include explosion-proof doors and shock-proof support systems. The explosion-proof doors can be stable and durable under the impact of explosions, effectively absorb and disperse impact energy, and protect the safety of internal personnel and facilities. The shock-proof support system absorbs and disperses seismic energy through components such as springs and shock absorbers, reduces the vibration amplitude and acceleration of the building, and reduces the damage caused by the impact.

[0004] However, the existing anti-impact structure of civil air defense equipment generally sets the anti-impact structure at a position such as the outside of the protective door, which greatly reduces the impact resistance of the door itself. This will make the door vulnerable to damage from explosions, collisions or other external impacts, and thus cannot effectively protect the safety of the internal area. Therefore, an anti-impact structure of civil air defense equipment is proposed to solve the above problem. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides an anti-impact structure for civil air defense equipment, aiming to improve the problem that the protective door itself has low impact resistance and cannot effectively protect the safety of the internal area in the existing anti-impact structure for civil air defense equipment in the prior art.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 3, the utility model provides an embodiment: an anti-impact structure of a civil air defense equipment, comprising a body 1, the outer wall of the body 1 is slidably connected to a door frame 2, a plurality of connecting blocks 3 are fixedly connected inside the body 1, a transmission rod 4 is rotatably connected inside the connecting block 3, and connecting blocks 2 5 are rotatably connected on both sides of the outer wall of the transmission rod 4, a sliding rod 6 is fixedly connected inside the body 1, the connecting block 2 5 is slidably connected to the outer wall of the sliding rod 6, a damper 1 7 is fixedly connected to one side of the outer wall of the connecting block 2 5, one end of the damper 1 7 is fixedly connected to one side of the outer wall of the connecting block 2 5, a spring 8 is fixedly connected to one side of the outer wall of the connecting block 2 5, one end of the spring 8 is fixedly connected to one side of the outer wall of the connecting block 2 5, a damper 2 9 is fixedly connected to one side of the outer wall of the connecting block 3, and one end of the damper 2 9 is fixedly connected to one side of the outer wall of the connecting block 3, and a transmission component is rotatably connected inside the body 1;

[0024] Specifically, in the anti-impact structure of the civil air defense equipment, when the main body 1 is subjected to external impact, the deformation of the main body 1 will drive the connecting block 3 to move a certain distance, and the impact force will be transmitted to the connecting block 3 through the main body 1. At this time, through the cooperation of the connecting block 3 and the damper 29, a part of the impact energy can be converted first, and the movement of the connecting block 3 will also drive the transmission rod 4 to move. At this time, the movement of the transmission rod 4 will drive the connecting block 25 to move. This makes the damper 17 and the spring 8 between the two connecting blocks 25 squeezed when they move relative to each other. At this time, the damper 17 and the spring 8 absorb and convert this force. This component enables the internal anti-impact structure to effectively absorb and disperse the impact energy when an explosion or other impact event occurs, thereby reducing the impact of external impact on the door body, thereby improving the overall safety of the door.

[0025] Reference Figure 1-Figure 3 The transmission assembly includes a bevel gear 11 and a bevel gear 2 12, the bevel gear 11 is meshed with the bevel gear 2 12, one side of the outer wall of the bevel gear 11 is rotatably connected to the inside of the body 1, the outside of the body 1 is rotatably connected to a rotating handle 10, and the body 1 and the door frame 2 are slidably connected to a bolt 19;

[0026] Specifically, when the anti-impact structure of the civil defense equipment is used, when the civil defense door is opened or closed, the bevel gear 11 can transmit the power of the rotating handle 10 to the bevel gear 2 12, so that it drives the worm 13 to rotate.

[0027] Reference Figure 1-Figure 3A worm 13 is fixedly connected to one side of the outer wall of the bevel gear 2 12, a worm wheel 14 is rotatably connected inside the body 1, the worm 13 meshes with the worm wheel 14, a bolt 19 is slidably connected inside the body 1 and the door frame 2, a disc 15 is rotatably connected inside the body 1, a rotating column 16 is fixedly connected to one side of the outer wall of the disc 15, a driving rod 17 is rotatably connected to the outer wall of the rotating column 16, a rotating column 2 18 is rotatably connected to one side of the outer wall of the driving rod 17, and a rotating column 2 18 is fixedly connected to one side of the outer wall of the bolt 19 on the outer wall of the rotating column 2, a sliding groove 20 is provided inside the body 1 and the door frame 2, and the outer wall of the bolt 19 is slidably connected to the inside of the sliding groove 20;

[0028] Specifically, in the anti-impact structure of the civil defense equipment, when the main body 1 needs to be opened, the rotating handle 10 is first rotated. Then, after the rotating handle 10 transmits power to the worm 13 through the bevel gear 11 and the bevel gear 2 12, the worm 13 drives the worm wheel 14 to rotate, so that the disc 15 is forced to rotate, and then the disc 15 drives the driving rod 17 to move through the rotating column 16. At this time, the movement of the driving rod 17 will drive the door bolt 19 to move toward the disc 15 through the rotating column 2 18, thereby releasing the limit on the main body 1, and then it can be opened. The reason why this structure uses the worm wheel 14 and worm 13 is that the worm wheel 14 and worm 13 transmission has the advantage of good self-locking. Due to the spiral shape of the worm 13, when the transmission force acts on the worm wheel 14, a torque is generated, which makes it impossible for the worm wheel 14 to freely rotate the worm 13. This self-locking property can prevent the reverse movement caused by the load on the worm wheel 14, thereby improving the stability and safety of the protective door.

[0029] Working principle: When the main body 1 is impacted in the anti-shock structure of the civil air defense equipment, the impact force is transmitted from the main body 1 to the connecting block 3. At this time, through the cooperation of the two inner and outer connecting blocks 3 and the damper 2 9, a part of the impact energy is gradually transformed. As the deformation generated when the main body 1 is impacted, the connecting block 3 drives the transmission rod 4 to move the connecting block 2 5, so that the two connecting blocks 2 5 move relative to each other, squeezing the damper 1 7 and the spring 8, and then the damper 1 7 and the spring 8 absorb and transform their energy to resist the impact caused by war or natural disasters, and effectively protect the safety of people's lives and property. When the door needs to be opened, the rotating handle 10 is first rotated, and then the rotating handle 10 drives the bevel gear 11 to rotate, and then the bevel gear 11 drives the bevel gear 2 12 to rotate, so that the bevel gear 2 12 drives the worm 13 to rotate, and the worm 13 drives the worm wheel 14 to rotate, thereby causing the disc 15 to rotate under force. When the disc 15 rotates, it will respectively drive the two rotating columns 16 to move, and then the rotating column 16 drives the driving rod 17 to move, and then the driving rod 17 drives the slide groove 20 to move toward the disc 15 through the rotating column 2 18 until the disc 15 is separated from the door frame 2, so that the body 1 can be opened with less manpower.
