Description

Technical Field

[0001] This application relates to the field of protective airtight doors, and in particular to a partition explosion-proof protective airtight door. Background Technology

[0002] A protective airtight door is a type of door capable of withstanding shock waves or the impact of heavy objects. Generally made of steel, it is a crucial component of door protection and falls under civil defense equipment, typically installed at the entrances and exits of protective engineering projects. Based on their function, protective doors can be categorized into airtight doors, blast wave-proof doors, and shielded doors. Blast wave-proof doors are often installed in areas storing flammable and explosive materials to prevent the spread of shock waves; small portions of the shock wave are gradually weakened to a safe range through diffusion. Additionally, shock-resistant protective doors are used in air raid defense and rescue operations to withstand nuclear or bomb impacts.

[0003] Existing explosion-proof airtight doors generally achieve the effect of resisting shock waves by increasing the thickness of the door. However, in order to facilitate opening and closing, the explosion-proof door still needs to be equipped with a swing mechanism or other switches on the outside to control the movement of the locking pin inside the door panel to lock it. However, the shock wave may deform these switches. After resisting the impact, due to the deformation, these explosion-proof doors may lock due to damage to the switches, making them difficult to open. Summary of the Invention

[0004] The purpose of this application is to provide a partition explosion-proof airtight door that can prevent the door panel from locking due to impact.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a partition explosion-proof protective airtight door, including a door frame, connectors, and a door panel. The door panel includes an outer panel, an inner lining panel, and a middle partition plate disposed between the two. An adjustment and locking mechanism is provided on the inner side of the outer panel, and an emergency locking structure is provided on the inner side of the inner lining panel. The middle partition plate has an opening connecting the outer panel and the inner lining panel. A buffer member is provided on the side of the adjustment and locking mechanism facing the inner lining panel. The buffer member is adapted to provide a buffering effect through elastic deformation. When the door is closed and subjected to an impact, the adjustment and locking mechanism moves toward the buffer member and releases the lock. At the same time, the adjustment and locking mechanism acts on the emergency locking mechanism to make the emergency locking mechanism lock. After the impact disappears, the emergency locking mechanism resets or partially resets, and the emergency locking mechanism resets accordingly to release the lock.

[0006] As a preferred embodiment, an outer protective plate is provided on the outer side of the partition, and a transmission space and a first locking space are formed on the outer protective plate. The adjusting locking mechanism includes a transmission part, a transmission component, and a locking component. The transmission part and the transmission component cooperate and are disposed in the transmission space, and the locking component is disposed in the first locking space. A limiting groove for restricting the sliding of the locking component is formed between the transmission space and the first locking space. The transmission component is adapted to drive the transmission part to move, and the transmission part is adapted to drive the locking component to protrude or retract from the door panel, so that the door panel is locked or unlocked to the door frame.

[0007] As a preferred embodiment, the transmission component is a gear, and the transmission part is a connecting rod with a rack. The gear is slidably installed at the opening of the partition plate, and an elastic buffer is provided at the inner liner plate. In the initial state, the gear teeth protrude from the opening. In the normal installation state, the rack of the connecting rod meshes with the gear. The connecting rod and the locking component together are provided with a first elastic element. In the initial state, the first elastic element prevents the locking component from extending out of the door panel. When the gear causes the locking component to extend out of the door panel and engage with the door frame, the first elastic element elastically deforms, and the gear locks the connecting rod and the locking component to prevent the first elastic element from causing the locking component to reset. When impacted, the gear moves towards the buffer until the gear is completely located in the opening. At this time, the connecting rod and the gear disengage, and the first elastic element resets to reset the locking component.

[0008] As a preferred embodiment, an inner protective plate is provided on the inner side of the partition, and a buffer space and a second locking space are formed on the inner protective plate. The emergency locking structure includes a buffer frame, a locking frame, and a drive plate. The drive plate is fixedly connected to the gear. The buffer frame restricts sliding within the buffer space. The buffer frame is adapted to drive the locking frame to move within the second locking space, so that the locking frame extends or retracts from the door panel, thereby locking and unlocking. The buffer frame is provided with a second elastic element. In its initial state, the second elastic element prevents the locking frame from extending from the door panel. When the door panel is impacted after being locked, the gear approaches the inner lining plate, and the drive plate acts on the buffer frame, causing the buffer frame and the locking frame to move towards the outside of the door panel. Consequently, the locking frame automatically extends from the door panel when the door panel is impacted and locks with the door frame. After the impact ends, the second elastic element resets, causing the locking frame to automatically retract.

[0009] As a preferred embodiment, the buffer frame is L-shaped, and two buffer frames are provided. After installation, the two buffer frames are in a centrally symmetrical posture, and both buffer frames slide along the horizontal straight line direction of the installation position.

[0010] As a preferred embodiment, the two buffer frames are installed in an interlocking posture, and each of the two buffer frames is provided with two second elastic members. The two buffer frames extend or retract along the two opposite side walls of the door panel to lock or unlock the door panel.

[0011] As a preferred embodiment, the drive plate includes a guide surface, a rectangular first closed area is formed between the two buffer frames, two second elastic elements are disposed within the first closed area, and a limit rod is provided within the first closed area. The limit rod causes the two buffer frames to slide along a straight line. When the door panel is closed and locked and subjected to an impact, the guide surface of the drive plate acts on the first closed area to bring the two buffer frames closer to each other, causing the locking frame to extend out of the door panel to lock with the door frame. After the impact ends, the second elastic elements reset to retract the locking frame.

[0012] As a preferred embodiment, the two buffer frames are installed in a back-to-back position, and each buffer frame is provided with a second elastic member. In the initial state, the two second elastic members bring the two buffer frames close together. When moving, the two buffer frames extend or retract along the two opposite side walls of the door panel to lock or unlock the door panel.

[0013] As a preferred embodiment, the drive plate includes a guide surface, and the two buffer frames cooperate with the two second elastic elements to form a rectangular second closed area. The outer diameter of the guide surface of the drive plate is smaller on the side closer to the second closed area.

[0014] As a preferred embodiment, one side of the second closed area has a large outer diameter. When impacted, the drive plate acts on the second closed area to move the two buffer frames away from each other, thereby extending them out of the door panel for locking. After the impact ends, the second elastic element resets, and the two buffer frames move closer together and retract into the door panel.

[0015] As a preferred embodiment, the door frame is formed with a limiting step suitable for abutting against the door panel, and the limiting step has a locking groove, through which the door panel is locked.

[0016] Compared with the prior art, the beneficial effects of this application are as follows:

[0017] When subjected to a significant impact, the adjusting locking mechanism automatically unlocks and triggers the emergency locking mechanism for temporary locking. Once the impact subsides, the lock is released. Therefore, even if the external adjusting locking mechanism is deformed or damaged by the impact, it will not affect subsequent door opening; in other words, it is not easily locked after a significant impact. The middle partition, outer panel, and inner panel divide the door panel into two parts along the middle partition. The outer panel contains a common adjusting locking mechanism, which uses a rotating gear to move a rack and pinion, extending the locking pin out of the door panel and inserting it into the door frame for locking. An emergency locking mechanism is added inside the middle partition. Protected by the middle partition, this mechanism is less prone to deformation; the space within the emergency locking mechanism inside the middle partition is less susceptible to deformation, thus making it less likely to jam under impact.

[0030] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0032] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0033] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0034] Example:

[0035] Reference Figure 1-10This embodiment proposes a partition explosion-proof protective airtight door, which mainly includes a door frame 1, a connector 3 and a door panel 8. The door panel 8 includes an outer panel, an inner lining panel 81 and a middle partition plate disposed between the two, and the three are fixedly connected. The middle partition plate has high toughness and strength, which can be achieved by increasing the thickness. The door frame 1 has a door groove 2, and the inner lining panel 81 is located in the door groove 2 when the door is closed.

[0036] Among them, such as Figure 3 , Figure 4As shown, an adjusting locking mechanism is provided on the inner side of the outer panel, and an emergency locking structure is provided on the inner side of the inner lining plate 81. An opening connecting the outer panel and the inner lining plate 81 is provided in the middle partition. A buffer member 20 is provided on the side of the adjusting locking mechanism facing the inner lining plate 81. The buffer member 20 is adapted to provide a buffering effect through elastic deformation. When the door is closed and subjected to an impact, the adjusting locking mechanism moves towards the buffer member 20 and releases the lock. Simultaneously, the adjusting locking mechanism acts on the emergency locking mechanism to lock the emergency locking mechanism. After the impact disappears, the emergency locking mechanism resets or partially resets, thus releasing the lock. Clearly, this invention, through the buffer member 20, allows the adjusting locking mechanism to act on the buffer member 20 to offset the impact when encountering a small impact force, through the deformation of the buffer member 20. When encountering a larger impact force, the adjusting locking mechanism causes the buffer member 20 to undergo a greater degree of deformation. At this time, the adjusting locking mechanism acts on the emergency locking mechanism, causing the emergency locking mechanism to change from a normal state to a locked state. After the impact ends, the buffer member 20 elastically resets, and the emergency locking mechanism releases the lock. In this embodiment, when a large impact occurs, the adjusting locking mechanism moves in the direction of the impact due to the impact force and automatically releases the lock. Meanwhile, the emergency locking mechanism located on the inner side automatically locks during this process, thus preventing the door panel 8 from being forced into the inner side of the door frame 1 by the impact force. The door panel 8 generally also has a limiting structure on the door frame 1, so the locking mechanism, combined with the emergency locking mechanism, can fully support the door panel 8. Clearly, the middle partition, outer panel, and inner panel divide the door panel 8 into two parts along the middle partition; the outer part is the outer panel, in which the... The system is equipped with a common adjustment and locking mechanism. This mechanism typically uses a rotating gear to move a rack and pinion, causing the locking pin to extend from the door panel 8 and insert into the door frame 1 for locking. An emergency locking mechanism is added inside the partition. This mechanism is protected by the partition and is not easily deformed, so it is not prone to jamming under impact. The outer adjustment and locking mechanism is different. If its adjustment part 5 is deformed by a large impact, it is easy to become unable to open. In actual operation, this would mean that the door cannot be opened after an impact. In this embodiment, the adjustment and locking mechanism automatically unlocks when subjected to a large impact and triggers the emergency locking mechanism for temporary locking. After the impact ends, the lock is also released. Therefore, even if the outer adjustment and locking mechanism is deformed or damaged by an impact, it will not affect subsequent door opening, meaning it is not easily locked after a large impact.

[0037] like Figure 3As shown, an outer protective plate 9 is provided on the outer side of the partition. A transmission space 14 and a first locking space 15 are formed on the outer protective plate 9. The adjusting locking mechanism includes a transmission part 12, a transmission component 13, and a locking component. The transmission part 12 and the transmission component 13 cooperate and are disposed in the transmission space 14. The locking component is disposed in the first locking space 15. A limiting groove 25 for limiting the sliding of the locking component is formed between the transmission space 14 and the first locking space 15. The transmission component 13 is adapted to drive the transmission part 12 to move. The transmission part 12 is adapted to drive the locking component to protrude or retract on the door panel 8 so that the door panel 8 is locked or unlocked on the door frame 1. The transmission component 13 is a gear, and the transmission part 12 is a connecting rod with a rack. The gear is slidably installed at the opening of the partition plate, and an elastic buffer 20 is provided at the inner liner plate 81. In the initial state, the gear teeth protrude from the opening. In the normal installation state, the rack of the connecting rod meshes with the gear. The connecting rod and the locking component are equipped with a first elastic element 11, preferably a spring. In the initial state, the first elastic element 11 prevents the locking component from extending out of the door panel 8. When the gear causes the locking component to extend out of the door panel 8 and engage with the door frame 1, the first elastic element 11 elastically deforms, and the gear locks the connecting rod and the locking component to prevent the first elastic element 11 from causing the locking component to reset. When impacted, the gear moves towards the buffer 20 until the gear is completely in the opening. At this time, the connecting rod and the gear disengage, and the first elastic element 11 resets to reset the locking component. Figure 3 As shown, two locking components are provided. The transmission parts 12 corresponding to the upper locking component 4 and the lower locking component 7 are located on both sides of the gear and drive simultaneously. The principle is relatively simple, which realizes that when the gear is rotated, the upper locking component 4 and the lower locking component 7 extend out of the door panel 8 or retract at the same time.

[0038] For the setting of the locking mechanism, refer to... Figure 1 , Figure 3 For example, as shown in the figure, the upper locking member 4 can have three locking posts. A connecting rod is provided at the bottom of each of the three locking posts, and this connecting rod is connected to the connecting rod of the transmission part 12. A limiting member 10 is also provided in the middle of the locking posts. The limiting member 10 is a structure that restricts the final position reached by the locking posts when the locking member is locked. The limiting member 10 abuts against the inner wall of the outer plate during locking. The first elastic member 11 can be as follows: Figure 3 The spring in the middle is fixedly installed on the connecting rod and the inner wall of the first locking space 15, respectively, so as to ensure that the upper locking member 4 and the lower locking member 7 do not protrude from the door panel 8 without the action of the gear (transmission member 13).

[0039] To ensure that the gear does not deflect when the adjusting part 5 on the outer side of the gear is subjected to a lateral impact, such as... Figure 3 , Figure 5As shown, a guide sleeve is provided on the outer side of the gear. This guide sleeve is fixedly installed on the partition plate. The channel in the center of the guide sleeve corresponds to the opening on the partition plate. In the initial state, the buffer 20 acts on the gear, causing the gear teeth to protrude from the guide sleeve. At this time, the transmission part 12 (rack) meshes with the gear. Then, rotating the adjustment part 5 can open or close the door normally. When the buffer 20 has a large elasticity, it is not easy to push the gear into the guide sleeve using the adjustment part 5. Under normal use, it is no different from a normal protective airtight door. When subjected to a large impact, the innermost side of the gear will move towards the inside of the guide sleeve until it disengages from the transmission part 12. At this time, the locking part will retract through the reset of the first elastic part 11, i.e., it will automatically unlock. At the same time, the inward stroke of the gear will cause the emergency locking mechanism to deform, thereby temporarily locking the door panel 8. After the impact ends, the buffer 20 will reset, thereby resetting the gear. At this time, the emergency locking mechanism can be unlocked, thus releasing the locked state. Since the transmission part 12 is driven by the first elastic element 11 to reset at this time, it may interfere with the gear reset. At this time, the adjustment part 5 can be rotated so that the gear direction corresponds to the rack, thereby resetting the adjustment locking mechanism; or the outer side of the adjustment part 5 is damaged and the gear cannot be fully reset, but can only partially return. At this time, it does not affect the emergency locking mechanism from being locked, nor does it affect the door panel 8 from being opened. However, at this time, it is necessary to repair or replace it according to the degree of damage to the outer side of the door panel 8.

[0040] For the buffer 20, the buffer 20 can be a structure similar to a spring-damped shock absorber, consisting of a sleeve and a spring, which is fixedly installed on the inner liner plate 81.

[0041] For outer protective plate 9, such as Figure 5 As shown, the outer protective plate 9 can be set as two pieces, which can be integrally formed with the partition. The two outer protective plates 9 form a transmission space 14, a first locking space 15 and a limiting groove 25, which facilitates the cooperation between the transmission part 12 and the transmission component 13, and also facilitates the installation of the upper locking component 4 and the lower locking component 7.

[0042] The guide sleeve provided in the above embodiments serves to guide the gear, ensuring the stability of the gear's path during movement. It also protects the gear from damage when subjected to significant impact, preventing it from becoming unable to move.

[0043] like Figure 4As shown, an inner protection plate 82 is provided on the inner side of the middle partition plate. A buffer space 16 and a second locking space 24 are formed on the inner protection plate 82. The emergency locking structure includes a buffer frame, a locking frame, and a driving plate 19. The driving plate 19 is fixedly connected to a gear. The buffer frame is restricted to slide within the buffer space 16. The buffer frame is adapted to drive the locking frame to move within the second locking space 24, so that the locking frame extends or retracts from the door panel 8, thereby performing locking and unlocking. The buffer frame is provided with a second elastic member 18. In the initial state of the second elastic member 18, the locking frame does not extend from the door panel 8. When the door panel 8 is locked and subjected to an impact, the gear approaches the inner lining plate 81, and the driving plate 19 acts on the buffer frame, so that the buffer frame and the locking frame move towards the outer side of the door panel 8. Furthermore, the locking frame automatically extends from the door panel 8 when the door panel 8 is impacted and is locked with the door frame 1. After the impact ends, the second elastic member 18 resets to automatically retract the locking frame. It is worth mentioning that the provided outer protection plate 9 and inner protection plate 82 also increase the thickness of the door panel 8 to a certain extent, making the door panel 8 stronger and able to withstand a greater impact force.

[0044] As Figure 4 、 Figure 8 shown, the buffer frame is L-shaped, and there are two buffer frames in total. After the two buffer frames are installed, they are in a centrosymmetric posture, and both buffer frames slide along the horizontal straight line direction of the installation position after installation.

[0045] For the setting of the buffer frame and the second elastic member 18, the following two preferred embodiment schemes are proposed:

[0046] (1) As Figure 4 、 Figure 8 shown, the two buffer frames, namely the first buffer frame 21 and the second buffer frame 22, are installed in an interlocking posture. After installation, they present a structure as Figure 8 shown, and its structure is similar to the mating state in the middle of the character "互". Two second elastic members 18 are correspondingly provided for the two buffer frames. The two buffer frames extend or retract respectively along the two opposite side walls of the door panel 8 to lock or unlock the door panel 8. Refer to Figure 4 and Figure 8The drive plate includes a guide surface, a rectangular first closed area is formed between the two buffer frames, two second elastic members 18 are disposed within the first closed area, and a limit rod 17 is provided within the first closed area. The limit rod 17 causes the two buffer frames to slide along a straight line. When the door panel 8 is closed and locked and is impacted, the guide surface of the drive plate acts on the first closed area to bring the two buffer frames closer together, causing the locking frame to extend out of the door panel 8 to lock with the door frame 1. After the impact, the second elastic members 18 reset to retract the locking frame. Obviously, in this embodiment, the outer diameter of the guide surface of the drive plate is larger on the side closer to the buffer member 20, and smaller on the side farther from the buffer member 20, with a larger initial diameter. One side of the outer diameter acts on the first closed area, so the two buffer frames are far apart. The distance between the two impact locking frames 23 on the outer side of the two buffer frames (which can be the structure shown in the figure, which is only a reference locking structure) is smaller. At this time, the impact locking frame 23 does not extend out of the door panel 8. When impacted, the guide surface moves closer to the buffer member 20. At this time, the outer diameter of the two buffer frames acting on the guide surface becomes smaller, and the two buffer frames are relatively closer. Obviously, the distance between the impact locking frames 23 on the outer side of the two buffer frames will increase, that is, they will extend out of the door panel 8. Thus, when subjected to a large impact force, the impact locking frame 23 can automatically extend out of the door panel 8 to lock.

[0047] Regarding the impact locking bracket 23, please refer to the settings of the locking components, such as... Figure 2 The sliding hole 6 is a slot for the impact locking bracket 23 to extend and retract.

[0048] (2) The two buffer frames are installed in a back-to-back position (of course, they are still centrally symmetrical). The structure of the two buffer frames can be referred to Figure 11 Two buffer frames are provided with two second elastic elements 18. In the initial state, the two second elastic elements 18 bring the two buffer frames closer together. When moving, the two buffer frames extend or retract along the two opposite side walls of the door panel 8 to lock or unlock the door panel 8. The drive plate at this time also includes a guide surface. The two buffer frames and the two second elastic elements 18 form a rectangular second closed area. The outer diameter of the guide surface of the drive plate is smaller on the side closer to the second closed area and larger on the side farther from the second closed area. It can be found that the guide surface should be opposite to that of the first (1) type. However, the principle of the two embodiments is the same. When impacted, the drive plate acts on the second closed area to make the two buffer frames move away from each other and extend out of the door panel 8 to lock. After the impact ends, the second elastic elements 18 reset, and the two buffer frames move closer together and retract into the door panel 8.

[0049] like Figure 1As shown, the door frame 1 has a limiting step suitable for abutting against the door panel 8. A locking groove is formed on the limiting step, through which the door panel 8 is locked. The aforementioned locking groove is a general description and does not specifically refer to, for example, the attached diagram. Figure 4 The upper locking element 4 and the impact locking bracket 23, and the locking groove can be configured as needed. Of course, the above two embodiments are only preferred solutions.

[0050] like Figure 1 As shown, in this embodiment, the connector 3 can be installed by pre-embedding, and part of the structure of the connector 3 is set in the wall, which can ensure that the connector 3 is not easily damaged when it is subjected to impact.

[0051] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.

At this time, the connecting rod and the gear disengage, and the first elastic element resets to reset the locking component.

3. The explosion-proof and airtight partition door as described in claim 2, characterized in that, The buffer frame is L-shaped, and there are two buffer frames. After installation, the two buffer frames are in a centrally symmetrical posture, and both buffer frames slide along the horizontal straight line of the installation position.

4. The explosion-proof and airtight partition door as described in claim 3, characterized in that, The two buffer frames are installed in an interlocking posture, and each of the two buffer frames is provided with a second elastic element. The two buffer frames extend or retract along the two opposite side walls of the door panel to lock or unlock the door panel.

5. The explosion-proof and airtight partition door as described in claim 4, characterized in that, The drive plate includes a guide surface, a rectangular first closed area is formed between the two buffer frames, two second elastic elements are disposed within the first closed area, and a limit rod is provided within the first closed area. The limit rod causes the two buffer frames to slide along a straight line. When the door panel is closed and locked and is impacted, the guide surface of the drive plate acts on the first closed area to bring the two buffer frames closer to each other, causing the locking frame to extend out of the door panel to lock with the door frame. After the impact ends, the second elastic elements reset to retract the locking frame.

6. The explosion-proof and airtight partition door as described in claim 3, characterized in that, The two buffer frames are installed in a back-to-back position, and each buffer frame is provided with a second elastic element. In the initial state, the two second elastic elements bring the two buffer frames closer together. When moving, the two buffer frames extend or retract along the two opposite side walls of the door panel to lock or unlock the door panel.

7. The explosion-proof and airtight partition door as described in claim 6, characterized in that, The drive plate includes a guide surface. The two buffer frames cooperate with the two second elastic elements to form a rectangular second closed area. The outer diameter of the guide surface of the drive plate is smaller on the side closer to the second closed area and larger on the side farther away from the second closed area. When impacted, the drive plate acts on the second closed area to make the two buffer frames move away from each other and extend out of the door panel for locking. After the impact ends, the second elastic elements reset, and the two buffer frames move closer together and retract into the door panel.

8. The explosion-proof and airtight partition door as described in claim 2, characterized in that, A guide sleeve is provided on the outer side of the gear. The guide sleeve is fixedly installed on the partition plate. The channel in the center of the guide sleeve corresponds to the opening on the partition plate. In the initial state, the buffer acts on the gear, causing the teeth of the gear to protrude from the guide sleeve, and the transmission part meshes with the gear.
