Description

Technical Field

[0001] This utility model relates to the field of civil defense door technology, specifically to a building-integrated, supportable, and retractable civil defense airtight door. Background Technology

[0002] Traditional methods of stacking airtight doors for civil defense purposes often involve direct stacking or simple support brackets, which presents numerous problems. When stacked directly, the lack of effective support between the doors can easily lead to door deformation, wear on the surface coating, and damage to protruding components such as adjusting screws after stacking, affecting subsequent installation and usability.

[0003] When using simple support brackets, the connection stability between the brackets and the air-raid shelter doors is poor, and there is a risk of tipping over during stacking, resulting in low safety. At the same time, traditional brackets are mostly fixed structures, which cannot be flexibly adjusted according to the size of the air-raid shelter doors, resulting in poor versatility. In addition, the brackets and air-raid shelter doors are designed separately, which makes storage and transportation inconvenient and increases labor and material costs. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated building-supporting and storage-capable airtight door for civil defense, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An integrated, retractable, airtight airtight door for civil defense includes a civil defense door, mounting ears, and an adjusting screw rod disposed on the upper surface of the civil defense door. It also includes a support and fixing assembly disposed below the adjusting screw rod and a support assembly disposed above the support and fixing assembly, wherein: The supporting and fixing assembly includes a limiting crossbar that is slidably connected to the upper surface of the air defense door. One end of the limiting crossbar is detachably and fixedly connected to an L-shaped mounting plate. An auxiliary locking assembly is provided at the end of the L-shaped mounting plate away from the limiting crossbar. The L-shaped mounting plate is detachably and fixedly connected to the mounting ear through the auxiliary locking assembly. The bottom surface of the limiting crossbeam is detachably fixedly connected to a fixing pad by insert bolts, and the bottom surface of the fixing pad is welded and fixed to the upper surface of the air-raid shelter door. The support assembly includes a horizontal I-beam 1 that is movably inserted into the inner wall of the limiting crossbeam. A vertical I-beam is movably engaged on the upper surface of the horizontal I-beam 1. A vertical connecting plate is fixedly connected to the side of the horizontal I-beam 1. An I-beam limiting groove is formed at the center of the upper surface of the vertical connecting plate. A second horizontal I-beam is movably inserted into the inner wall of the I-beam limiting groove.

[0006] A further improvement of the present invention is that the auxiliary locking component includes a limiting rod that is movably inserted into the inner wall of the mounting ear. A sleeve fixedly connected to the bottom end of the L-shaped mounting plate is movably sleeved on the outer wall of one end of the limiting rod. A pin hole is opened on the outer wall of one end of the limiting rod, and a limiting pin is movably inserted into the inner wall of the pin hole.

[0007] A further improvement of this utility model is that: a docking slot is provided on the bottom surface of one end of the limiting crossbeam near the L-shaped mounting plate; one end of the L-shaped mounting plate is movably inserted into the inner wall of the docking slot through a docking insert plate; the insert plate bolt passes through the limiting crossbeam, the docking insert plate and the fixing pad sequentially from top to bottom; and the upper surface of the docking insert plate is provided with mounting holes that are compatible with the insert plate bolt.

[0008] A further improvement of the present invention is that: the bottom surface of the transverse I-beam is provided with a crossbeam slot adapted to the limiting crossbeam, the inner wall of the crossbeam slot is slidably engaged with the limiting crossbeam, and a permanent magnet block is fixedly connected to the inner wall of the crossbeam slot on one side, and the permanent magnet block is magnetically attracted to the outer wall of the limiting crossbeam.

[0009] A further improvement of the present invention is that: both ends of the horizontal I-beam are fixedly connected with blocks for locking and limiting the vertical I-beam, and a rubber friction pad is fixedly connected to the top of the vertical I-beam.

[0010] A further improvement of this utility model is that the number of the transverse I-beams is two sets, and the two sets of transverse I-beams are symmetrically distributed along the vertical center line of the I-beam limiting groove.

[0011] A further improvement of this utility model is that the number of the supporting and fixing components is two sets, and the two sets of supporting and fixing components are symmetrically distributed along the vertical center line of the I-beam limiting groove.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. This utility model provides an integrated, supportable, and retractable airtight door for civil defense, achieving multi-point stable support for the door through the coordinated operation of the support and fixing components. The support and fixing components utilize a limiting crossbeam, an L-shaped mounting plate, and auxiliary locking components to securely connect with the mounting ears, ensuring a firm connection between the support structure and the civil defense door and preventing displacement during stacking. The combination of horizontal H-beam one, vertical H-beam one, and horizontal H-beam two in the support components forms a three-dimensional support system, effectively distributing the weight of the civil defense door, preventing door deformation, and simultaneously preventing damage to components such as the adjusting screw from compression.

[0013] 2. This utility model provides an integrated, retractable, and supportable airtight door for civil defense. The horizontal H-beam one, vertical H-beam, and horizontal H-beam two in the support assembly are all detachable. The L-shaped mounting plate in the support fixing assembly can be separated from the limiting crossbeam, facilitating the storage and transportation of components. For short-term storage, some components can be disassembled to reduce space occupation. The limiting crossbeam can be transferred along with the civil defense door or installed directly without separate storage, improving ease of use.

[0014] 3. This utility model provides an integrated, supportable, and retractable airtight door for civil defense. The support and fixing components are fixedly connected to the civil defense door via fixing pads, achieving an integrated design of the support structure and the civil defense door. This eliminates the need for additional independent supports, reducing transportation and management costs. Furthermore, the structure can be flexibly adjusted according to stacking needs, making it suitable for stacking different quantities of civil defense doors in different scenarios, demonstrating strong versatility.

[0015] 4. This utility model provides an integrated, supportable, and retractable airtight door for civil defense. A horizontal I-beam slides into a limiting crossbeam via a crossbeam slot, allowing for fine-tuning along the extension line of the limiting crossbeam to facilitate adjustment of the support position according to actual needs. The auxiliary locking assembly, through the cooperation of a limiting rod, sleeve, and limiting pin, enables rapid installation and disassembly of the L-shaped mounting plate and mounting ears, improving construction efficiency.

[0019] The present invention will be further described in detail below with reference to embodiments: Example 1

[0020] like Figure 1-6 As shown, this utility model provides an integrated, supportable, and retractable airtight door for civil defense, including a civil defense door 1, mounting ears 5, and an adjusting screw 2 disposed on the upper surface of the civil defense door 1. It also includes a support and fixing assembly 3 disposed below the adjusting screw 2 and a support assembly 4 disposed above the support and fixing assembly 3, wherein: like Figure 2 , Figure 3 , Figure 4 and Figure 6 The supporting and fixing component 3 includes a limiting crossbeam 6 that is slidably connected to the upper surface of the air defense door 1. One end of the limiting crossbeam 6 is detachably fixedly connected to an L-shaped mounting plate 7. An auxiliary locking component is provided at the end of the L-shaped mounting plate 7 away from the limiting crossbeam 6. The L-shaped mounting plate 7 is detachably fixedly connected to the mounting ear 5 through the auxiliary locking component. The bottom surface of the limiting crossbar 6 is detachably fixed to a fixing pad 11 via a plate bolt 10. The bottom surface of the fixing pad 11 is welded and fixed to the upper surface of the air-raid shelter door 1.

[0021] The auxiliary locking assembly includes a limiting rod 8 that is movably inserted into the inner wall of the mounting ear 5. A sleeve 13 that is fixedly connected to the bottom end of the L-shaped mounting plate 7 is movably sleeved on the outer wall of one end of the limiting rod 8. A pin hole is opened on the outer wall of one end of the limiting rod 8, and a limiting pin 12 is movably inserted into the inner wall of the pin hole.

[0022] The bottom surface of the limiting crossbeam 6 near the L-shaped mounting plate 7 has a docking slot 14. One end of the L-shaped mounting plate 7 is movably inserted into the inner wall of the docking slot 14 through the docking insert plate 9. The insert bolt 10 passes through the limiting crossbeam 6, the docking insert plate 9 and the fixing pad 11 from top to bottom. The upper surface of the docking insert plate 9 has a mounting hole that matches the insert bolt 10.

[0023] There are two sets of support and fixing components 3, which are symmetrically distributed along the vertical center line of the I-beam limiting groove 19.

[0024] In this embodiment, one end of the limiting crossbeam 6 is inserted below the adjusting screw 2 near one end, and then the limiting rod 8 is inserted into the mounting ear 5 and fitted therewith. Next, the sleeve 13 is fitted onto the limiting rod 8. At this time, the L-shaped mounting plate 7 moves laterally and fits against one side of the mounting ear 5, and the limiting crossbeam 6 is placed parallel to the width direction of the air-raid shelter door 1. Then, the limiting pin 12 is inserted into one end of the limiting rod 8 to limit and fix it.

[0025] When it is necessary to stack the air defense door 1 for a short period of time, the fixed relationship between the limiting crossbeam 6 and the L-shaped mounting plate 7 can be released after the stacking is completed. First, remove the limiting rod 8 from the mounting ear 5, then remove the plate bolt 10, pull the L-shaped mounting plate 7 outward to separate the connecting plate 9 from the limiting crossbeam 6, and then reset the plate bolt 10 to connect the plate bolt 10 with the fixing pad 11, thereby fixing the limiting crossbeam 6 and the fixing pad 11. Example 2

[0026] like Figure 2 and Figure 6 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the support component 4 includes a horizontal I-beam 15 that is movably inserted into the inner wall of the limiting crossbeam 6, a vertical I-beam 17 that is movably snapped onto the upper surface of the horizontal I-beam 15, a vertical connecting plate 18 that is fixedly connected to the side of the horizontal I-beam 15, an I-beam limiting groove 19 that is opened at the center of the upper surface of the vertical connecting plate 18, and a horizontal I-beam 2 16 that is movably inserted into the inner wall of the I-beam limiting groove 19.

[0027] The bottom surface of the transverse I-beam 15 is provided with a crossbeam slot 22 that is adapted to the limiting crossbeam 6. The inner wall of the crossbeam slot 22 is slidably engaged with the limiting crossbeam 6. A permanent magnet block 23 is fixedly connected to the inner wall of the crossbeam slot 22 near one side. The permanent magnet block 23 is magnetically attracted to the outer wall of the limiting crossbeam 6.

[0028] Both ends of the horizontal I-beam 15 are fixedly connected to stop blocks 21 for locking and limiting the vertical I-beam 17, and the top of the vertical I-beam 17 is fixedly connected to a rubber friction pad 20.

[0029] There are two sets of transverse I-beams 15, and the two sets of transverse I-beams 15 are symmetrically distributed along the vertical center line of the I-beam limiting groove 19.

[0030] In this embodiment, after both sets of limiting crossbeams 6 are installed in place, the transverse I-beam 15 is connected to the limiting crossbeam 6, the crossbeam slot 22 at the bottom of the transverse I-beam 15 is engaged with the upper edge of the limiting crossbeam 6, and the bottom of the transverse I-beam 15 abuts against the upper surface of the air defense door 1. At this time, the transverse I-beam 15 can be slid to move and finely adjust along the extension line of the limiting crossbeam 6. The permanent magnet block 23 provides magnetic attraction to assist in fixing the transverse I-beam 15. Example 3

[0031] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the air-raid shelter door 1 is made of steel plate to ensure structural strength and protective performance; the limiting crossbeam 6 and the L-shaped mounting plate 7 are made of high-strength alloy steel to improve support stability; the horizontal I-beam 15, the vertical I-beam 17, and the horizontal I-beam 2 16 are made of ordinary carbon structural steel to balance strength and economy; the fixing pad 11 is made of steel plate to ensure a firm connection with the air-raid shelter door 1; the limiting rod 8 and the limiting pin 12 are made of stainless steel to prevent corrosion; the sleeve 13 is made of cast iron to improve wear resistance; and the permanent magnet block 23 is made of neodymium iron boron permanent magnet to ensure magnetic attraction and fixing effect.

[0032] The upper surface of the horizontal I-beam 15 is provided with a slot that is compatible with the vertical I-beam 17. The bottom of the vertical I-beam 17 is inserted into the slot. The stop block 21 limits the two sides of the vertical I-beam 17. At the same time, the inner wall of the slot is interference-fitted with the outer wall of the vertical I-beam 17 to further improve the stability of the connection.

[0033] The working principle of this integrated airtight door for civil defense that can support and store is explained in detail below.

[0034] like Figure 1-6 As shown, when the air-raid shelter doors 1 need to be stacked flat, first place the bottom air-raid shelter door 1 flat on a suitable ground or platform. Then, insert one end of the limiting crossbar 6 into the lower part of the adjusting screw 2 near one end, and then insert the limiting rod 8 into the mounting ear 5 and make it fit against it. Next, put the sleeve 13 onto the limiting rod 8. At this time, the L-shaped mounting plate 7 moves laterally and fits against one side of the mounting ear 5, and the limiting crossbar 6 is placed parallel to the width direction of the air-raid shelter door 1. Then, insert the limiting pin 12 into one end of the limiting rod 8 to limit and fix it.

[0035] After both sets of limiting crossbeams 6 are installed in place, the transverse I-beam 15 is connected to the limiting crossbeam 6. The crossbeam slot 22 at the bottom of the transverse I-beam 15 is engaged with the upper edge of the limiting crossbeam 6, and the bottom of the transverse I-beam 15 abuts against the upper surface of the air defense door 1. At this time, the transverse I-beam 15 can be slid to move and finely adjust along the extension line of the limiting crossbeam 6. The permanent magnet block 23 provides magnetic attraction to assist in fixing the transverse I-beam 15.

[0036] According to usage requirements, the second horizontal I-beam 16 can be installed in the center of the vertical connecting plate 18, that is, in the inner wall of the I-beam limiting groove 19, so as to form multi-point support after the vertical I-beam 17 is installed in place. After the first horizontal I-beam 15 is installed, there are a total of six sets. The number of vertical I-beams 17 corresponds to the number of horizontal I-beams 15. Then, another air-raid shelter door 1 can be stacked on the upper surface of the vertical I-beam 17. Through the cooperation and support of the first horizontal I-beam 15 and the vertical I-beam 17, sufficient gap is left between the two air-raid shelter doors 1 to avoid squeezing the relevant parts of the adjusting screw 2.

[0037] When short-term stacking of the air-raid shelter door 1 is required, the fixing relationship between the limiting crossbeam 6 and the L-shaped mounting plate 7 can be released after stacking. First, remove the limiting rod 8 from the mounting ear 5, then remove the insert bolt 10, pull the L-shaped mounting plate 7 outward to separate the connecting insert plate 9 from the limiting crossbeam 6, and then reset the insert bolt 10 to connect it with the fixing pad 11, thereby fixing the limiting crossbeam 6 and the fixing pad 11. For subsequent use, the horizontal I-beam 15 and the vertical I-beam 17 can be removed, and the limiting crossbeam 6 can be transferred with the air-raid shelter door 1 or installed directly without disassembly. If the air-raid shelter door 1 needs to be stacked for a longer period of time, the L-shaped mounting plate 7 can be installed without removing it, and the mounting ear 5 can be used to form a more stable limiting effect.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
