[0002] Civil defense doors are the doors at the entrances and exits of civil defense projects. The use of civil defense doors is of great significance in ensuring public safety, providing protective measures, and achieving air isolation and sealing functions. Civil defense doors are clearly classified, including ordinary single and double-leaf protective airtight doors and airtight doors, as well as single and double-leaf protective airtight doors and airtight doors with movable thresholds, and other types of civil defense equipment. When using civil defense doors, lightweight support components can be used to support the open civil defense doors.

[0003] A common type of lightweight support component for air defense doors has some problems. For example, when using air defense doors, the lightweight support component is needed to support the doors, but when closing the doors, the support component needs to be raised into the pre-reserved slot. It is inconvenient to adjust the height of the support component according to the needs, and it can easily affect the opening and closing of the air defense doors.

[0004] Therefore, we propose an adjustable lightweight support assembly for air defense doors to improve upon the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable lightweight support component for air defense doors, so as to solve the problem mentioned in the background art that it is inconvenient to adjust the height of the support component according to the needs, which easily affects the opening and closing of air defense doors.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable lightweight support component for a civil defense door, comprising a frame, wherein a door body is movably hinged inside the frame, and a reserved groove is provided at the bottom right side of the door body, wherein an adjustment structure for supporting the door body is provided inside the reserved groove.

[0007] The adjustment structure includes a gear, a support rack, and a throttle. A rotating shaft is movably connected to the left side inside the reserved slot. A throttle is fixedly connected to the front end of the rotating shaft. A gear is fixedly connected to the outside of the rotating shaft. A support rack is provided on the right side inside the reserved slot. An anti-slip support block is fixedly connected to the bottom end of the support rack.

[0008] As a further technical solution of this utility model, the gear has tooth blocks machined on its outer side, and the supporting rack has tooth blocks on its left side that are the same as the tooth blocks on the outer side of the gear, and the gear and the supporting rack cooperate with each other.

[0009] As a further technical solution of this utility model, the anti-slip support block is set inside the reserved groove, and the support rack is set on the right side of the gear.

[0010] As a further technical solution of this utility model, a fixing plate is fixedly connected to the front end of the door body, a limiting groove is fixedly connected to the right side of the top of the fixing plate, a support rod is provided inside the limiting groove, a pull plate is provided at the top of the fixing plate, a limiting rod is fixedly connected to the bottom end of the pull plate, a spring is fixedly connected between the fixing plate and the pull plate, and a fixing hole is provided on the outer side wall of the handle.

[0011] As a further technical solution of this utility model, the fixing holes are processed in multiple sets, and the fixing holes are distributed in a ring on the outer side wall of the throttle.

[0012] As a further technical solution of this utility model, the bottom end of the limiting rod is embedded inside the fixing hole, and the spring is disposed outside the limiting rod.

[0013] As a further technical solution of this utility model, the front and rear ends of the supporting rack are fixedly connected to connecting rods, and the side of the connecting rods near the outside is fixedly connected to a limiting slider. Limiting grooves are opened at the front and rear ends inside the reserved groove.

[0014] As a further technical solution of this utility model, the limiting slider is disposed inside the limiting groove, and the limiting slider slides up and down inside the limiting groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the adjustable lightweight support component for the air defense door not only makes it easy to adjust the support component and prevents the handle from turning accidentally, but also improves the stability of lifting and lowering.

[0016] (1) The door is equipped with gears, support racks, anti-slip support blocks, a handle and a shaft. When one side of the door needs to be supported, the handle is turned and the handle drives the gear to rotate through the shaft. Since the gears and support racks cooperate with each other and the anti-slip support blocks are fixedly connected to the bottom of the support racks, the rotation of the gears can cause the support racks to drive the anti-slip support blocks to descend, so that the anti-slip support blocks can contact the ground to support the door and prevent one side of the door from being suspended and affecting its service life. When the door needs to be closed, the handle is reversed to raise the anti-slip support blocks into the pre-reserved groove.

[0017] (2) By setting a fixed plate, a fixed hole, a limiting rod, a pull plate, a spring, a support rod and a limiting groove, the pull plate is pulled to make the limiting rod rise, and then the support rod is pushed to move to the bottom of the pull plate to limit the pull plate. This allows the limiting rod to disengage from the inside of the fixed hole, causing the throttle to lose its fixed position. After adjusting to the appropriate position, the support rod is pushed to make the pull plate lose its fixed position. After the pull plate loses its fixed position, the spring uses its own elasticity to make the limiting rod embedd in the inside of the fixed hole to limit and fix the throttle, preventing the throttle from rotating unexpectedly and affecting its use.

[0018] (3) By setting a limiting groove, a limiting slider and a connecting rod, when the gear drives the support rack to rise and fall, the limiting slider near the outer end of the connecting rod will slide up and down inside the limiting groove, thereby limiting the support rack and preventing the support rack from being misaligned with the tooth blocks on the support rack and the tooth blocks outside the gear when it rises and falls.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 The present invention provides an embodiment of an adjustable lightweight support component for a civil defense door, comprising a frame 1, a door body 2 hinged inside the frame 1, a reserved groove 3 at the bottom right side of the door body 2, and an adjustment structure for supporting the door body 2 provided inside the reserved groove 3.

[0026] The adjustment structure includes a gear 4, a support rack 6 and a throttle 10. A rotating shaft 11 is movably connected to the left side inside the reserved groove 3. The throttle 10 is fixedly connected to the front end of the rotating shaft 11. A gear 4 is fixedly connected to the outside of the rotating shaft 11. A support rack 6 is provided on the right side inside the reserved groove 3. An anti-slip support block 9 is fixedly connected to the bottom end of the support rack 6.

[0027] Gear 4 has tooth blocks machined on its exterior, and the left side of the supporting rack 6 has tooth blocks that are the same as the tooth blocks on the exterior of gear 4. Gear 4 and supporting rack 6 cooperate with each other. Anti-slip support block 9 is set inside the reserved groove 3, and supporting rack 6 is set on the right side of gear 4.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when one side of the door 2 needs support, turn the handle 10. The handle 10 drives the gear 4 to rotate through the shaft 11. Since the gear 4 and the support rack 6 cooperate with each other, and the anti-slip support block 9 is fixedly connected to the bottom of the support rack 6, the rotation of the gear 4 can cause the support rack 6 to drive the anti-slip support block 9 to descend, so that the anti-slip support block 9 can contact the ground to support the door 2 and prevent one side of the door 2 from being suspended and affecting its service life. When the door 2 needs to be closed, reverse the handle 10 to raise the anti-slip support block 9 into the interior of the reserved groove 3.

[0029] A fixing plate 5 is fixedly connected to the front end of the door body 2. A limiting groove 18 is fixedly connected to the right side of the top of the fixing plate 5. A support rod 17 is provided inside the limiting groove 18. A pull plate 15 is provided at the top of the fixing plate 5. A limiting rod 14 is fixedly connected to the bottom end of the pull plate 15. A spring 16 is fixedly connected between the fixing plate 5 and the pull plate 15. A fixing hole 13 is opened on the outer side wall of the throttle 10. Multiple sets of fixing holes 13 are machined. The fixing holes 13 are distributed in a ring on the outer side wall of the throttle 10. The bottom end of the limiting rod 14 is embedded in the fixing hole 13. The spring 16 is provided on the outside of the limiting rod 14.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, pulling the pull plate 15 causes the pull plate 15 to drive the limiting rod 14 to rise, and then pushing the support rod 17 causes the support rod 17 to move to the bottom end of the pull plate 15 to limit the pull plate 15. This allows the limiting rod 14 to disengage from the inside of the fixing hole 13, causing the throttle 10 to lose its fixed position. After adjusting to the appropriate position, pushing the support rod 17 causes the pull plate 15 to lose its fixed position. After the pull plate 15 loses its fixed position, the spring 16 uses its own elasticity to make the limiting rod 14 embedded in the inside of the fixing hole 13 to limit and fix the throttle 10, preventing the throttle 10 from rotating accidentally and affecting its use.

[0031] The front and rear ends of the support rack 6 are fixedly connected to the connecting rod 12. The side of the connecting rod 12 near the outside is fixedly connected to the limiting slider 8. The front and rear ends of the reserved groove 3 are opened with limiting slide grooves 7. The limiting slider 8 is set inside the limiting slide groove 7 and slides up and down inside the limiting slide groove 7.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the gear 4 drives the support rack 6 to rise and fall, the limiting slider 8 at the outer end of the connecting rod 12 will slide up and down inside the limiting groove 7, thereby limiting the support rack 6 and preventing the support rack 6 from being misaligned with the tooth blocks on the support rack 6 and the tooth blocks outside the gear 4 during the rise and fall.

[0033] Working Principle: When using this invention, after opening the door 2 and pulling it to the appropriate position, pull the pull plate 15 to raise the limiting rod 14. Then, push the support rod 17 to move it to the bottom of the pull plate 15, limiting it. This allows the limiting rod 14 to disengage from the fixing hole 13, causing the handle 10 to lose its fixation. Rotating the handle 10 then drives the gear 4 via the shaft 11. Since the gear 4 and the support rack 6 cooperate, and the anti-slip support block 9 is fixedly connected to the bottom of the support rack 6, the rotation of the gear 4 causes the support rack 6 to lower the anti-slip support block 9. This allows the anti-slip support block 9 to contact the ground and support the door 2, preventing the door 2 from slipping. Side suspension affects service life. When the door 2 needs to be closed, reverse the handle 10 to raise the anti-slip support block 9 into the reserved groove 3 to prevent the support component from affecting the closing of the door 2. When the gear 4 drives the support rack 6 to rise and fall, the limiting slider 8 near the outer end of the connecting rod 12 will slide up and down inside the limiting groove 7, thereby limiting the support rack 6 and preventing the support rack 6 from being misaligned with the teeth on the support rack 6 and the teeth outside the gear 4 during rising and falling. After adjusting to the appropriate position, push the support rod 17 to make the pull plate 15 lose its fixation. After the pull plate 15 loses its fixation, the spring 16 uses its own elasticity to make the limiting rod 14 embedded in the fixing hole 13 to limit and fix the handle 10, preventing the handle 10 from rotating accidentally and affecting use.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
