[0001] The utility model relates to the field of building components, in particular to a detachable lifting ring for civil air defense doors. Background Art
[0002] In the prior art, the size of the lifting ring is generally 100 - 150 mm. In the actual design process, it is often required to reserve a total space height of 300 mm above the door height to ensure the opening of the civil air defense door. Frequently, there are water and electricity / hvac pipelines passing through both sides of the civil air defense door. Considering the structural height and the height of the equipment pipelines, plus the above-mentioned reserved height of 300 mm, this position has become a bottleneck for the floor height of the entire basement. Because the basement has to meet the height requirements of these points, the floor height of the entire basement is increased, resulting in waste. Summary of the Utility Model

[0043] Embodiment 1;
[0044] According to Figure 1 As shown, a detachable lifting ring for a civil air defense door includes a civil air defense door 1, a pre-embedded component 2, and a lifting ring component 3. Among them, the pre-embedded component 2 is installed and fixed in the civil air defense door 1, and the lifting ring component 3 is detachably connected to the pre-embedded component 2.
[0045] By setting the pre-embedded component 2, the present utility model detachably connects the lifting ring 31 to the civil air defense door 1, while ensuring the structural strength, and solves the problem of wasted floor height caused by the prior art.
[0046] In this embodiment, different from Embodiment 1, the pre-embedded component 2 includes a longitude pipe 21 and a latitude pipe 22. Among them, both the longitude pipe 21 and the latitude pipe 22 are installed in the civil air defense door 1 before pouring. The longitude pipe 21 and the latitude pipe 22 are fixedly connected by welding. The upper end of the longitude pipe 21 is flush with the upper surface of the civil air defense door 1, and a threaded hole is provided at the upper end of the longitude pipe 21, so that the lifting ring component 3 is installed and fixed by threaded connection to the longitude pipe 21.
[0047] Through the longitude pipe 21 and the latitude pipe 22 of the pre-embedded component 2, when the lifting ring component 3 lifts the civil air defense door 1, it will not fall due to insufficient structural strength and breakage.
[0048] In this embodiment, the lifting ring component 3 includes a lifting ring 31, a screw rod 32, and a double-headed nut 33. Among them, an installation part is provided on the lifting ring 31 and is fixedly connected to one end of the double-headed nut 33. One end of the screw rod 32 is fixedly connected to the other end of the double-headed nut 33, and the other end of the screw rod 32 is fixedly connected to the threaded hole of the longitude pipe 21.
[0049] The lifting ring component 3 of the present utility model uses a double-headed nut 33 to fixedly connect the lifting ring 31 and the civil air defense door 1 through the double-headed nut 33 and the screw rod 32, realizing a detachable connection. After the civil air defense door 1 is installed, the lifting ring 31, the screw rod 32, and the double-headed nut 33 can be removed.
[0050] In this embodiment, at least two installation parts are provided below the lifting ring 31, and the corresponding screw rod 32 and double-headed nut 33 are also the same in number as the installation parts. Among them, in one civil air defense door 1, there are also at least two longitude pipes 21.
[0051] By setting two installation parts, the present utility model makes the force more uniform when the civil air defense door 1 is lifted.
[0052] Embodiment 2
[0053] According toFigures 2 - 3 Based on Embodiment 1, the differences from Embodiment 1 are as follows:
[0054] In this embodiment, the screw 32 has an opening on the bottom surface, and the opening extends to the middle of the screw 32. The radius of the inner circle of the longitude tube 21 is greater than the radius of the screw 32, and there is a protrusion 321 on the bottom side of the screw 32.
[0055] In this embodiment, there is an installation groove 211 on the side wall of the inner bottom surface of the longitude tube 21, and there is a convex block 212 on the bottom surface.
[0056] The utility model hoists the civil air defense door 1 by arranging the screw 32 with an opening on the bottom surface and the installation groove 211 with a convex block 212 on the bottom surface, and clamping the protrusion 321 and the installation groove 211 by the convex block 212.
[0057] In this embodiment, the lifting ring assembly 3 further includes an annular cushion block removing part. When the screw 32 needs to be removed, the annular cushion block removing part is placed along the space between the screw 32 and the longitude tube 21 to remove the screw 32.
[0058] In this embodiment, the spiral directions of the internal threads of the upper head and the lower head of the double-headed nut 33 are opposite.
[0059] In this embodiment, the lifting ring 31 and its installation part are integrally formed.
[0060] In this embodiment, there are 4 longitude tubes 21 and at least 8 latitude tubes 22. The outer contour shapes of the cross-sections of the longitude tubes 21 and the latitude tubes 22 are both rectangular.
[0061] Embodiment 3
[0062] According to Figures 4 - 5 shown, based on Embodiment 1 or 2, the differences from Embodiment 1 or 2 are as follows:
[0063] The lifting ring assembly 3 includes a screw one 34, a screw two 35, and a fixing nut 36. The lower ends of the screw one 34 and the screw two 35 are directly connected to the longitude tube 21 in the manner of Embodiment 1 or Embodiment 2. Right-angle bends are provided at the upper ends of the screw one 34 and the screw two 35, and threads are provided at the bent parts. After the screw one 34 and the screw two 35 are respectively installed and fixed on the longitude tube 21, the bent parts of the screw one 34 and the screw two 35 are connected and fixed by the fixing nut 36.
[0064] This embodiment simplifies the structure of the lifting ring 31 by improving the shape of the screw 32, so that the screw 32 directly becomes the lifting ring 31 after being connected by the fixing nut 36, greatly saving costs.
[0065] Embodiment 4
[0066] According toFigures 6 - 7 As shown, in this embodiment, different from Embodiment 3, the embedded component 2 is a hollow special-shaped prism on the upper surface. The shape of the special-shaped prism is a large cuboid with a small cuboid cut off. Specifically, in the top-down view, the upper surface of the small cuboid coincides with the upper surface of the large cuboid, and any one vertex of the two also coincides, so that the cross-sectional shape of the embedded component is an L shape, and the longitudinal-sectional shape is also an L shape.
[0067] In addition, another difference is that the lower-end shapes of the first screw 34 and the second screw 35 correspond to the inner cavity shape of the embedded component 2. After the first screw 34 and the second screw 35 are inserted from above the embedded component 2 and then translated inward, the first screw 34 and the second screw 35 are fixed in the embedded component 2 so that they will not fall off when lifted.
[0068] It can be understood that the embedded component 2 can directly drill a hole above the air defense door, and the shape of the hole is the same as the inner cavity shape of the embedded component 2. This solution is also an optional solution in this embodiment.
[0069] The specific embodiments described above further elaborate on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above description is only the specific embodiments of the present invention and is not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
