Description

Technical Field

[0001] This invention belongs to the field of security door technology, specifically a marine fireproof and anti-theft dual-purpose security door. Background Technology

[0002] A door is an opening for people or things to enter and exit. It is usually composed of a door frame, door leaf, door lock, etc. There are many types of doors, such as automatic doors, fire doors, security doors, etc. In the event of a fire, the structure and materials of the door can block the spread of fire and smoke to protect the safety of people and property. In normal times, closing the door can prevent the theft of important items.

[0003] On a ship, the interior is divided into multiple areas, each requiring different preventative measures. Therefore, different doors are typically used for each area. Traditional doors have a limited function, and even if they offer additional protection, they cannot provide comprehensive protection. Ships also have various types of doors, such as sliding doors. While sliding doors offer good sealing and fire resistance, their overall security and stability are lower because the door panel is fixed to a track on the outside of the frame. Furthermore, these doors are usually single-layered panels filled with fire-resistant material, which means that in the event of a fire, the door panel's temperature will rise directly, potentially damaging the track. Therefore, a dual-purpose fireproof, anti-theft, and security door for ships is proposed. Summary of the Invention

[0010] Preferably, the second door panel body is movably connected inside the first door panel body, the limiting link extends through the fireproof filling layer and the partition plate to the interior of the first door panel body, the rigid spring is located inside the first door panel body and is fixedly connected to the first door panel body, the limiting link corresponds to the position of the pressure switch, the pressure switch is located inside the rigid spring, the heat-conducting metal fork extends through the fireproof filling layer and the partition plate to the interior of the central slide rail, and the heat-conducting metal fork contacts the plastic connector.

[0011] Preferably, the fixing component includes a pair of support frames, each of the left and right ends of the pair of support frames is fixedly connected to a first spring, and each of the two support frames is hinged to a pair of sliding links on the side away from each other, with the end of the sliding link away from the support frame being rotatably connected to a fixed link.

[0012] Preferably, one end of the support frame that is close to the other is slidably connected to the inside of the middle slide rail, the support frame is slidably connected to the vertical slide rod, the first spring is wrapped around the middle of the vertical slide rod, the first spring is fixedly connected to the first door panel body, and a fixing slot is provided at one end of the support frame located inside the middle slide rail.

[0013] Preferably, the sliding link consists of two parts: a flipping rod and a push rod. The flipping rod is located between the support frame and the push rod, and its two ends are hinged to the support frame and the push rod, respectively. The push rod is slidably connected inside the vertical groove and is rotatably connected to the fixed link. The fixed link consists of two parts: a pressing rod and a fixing block. Both the pressing rod and the fixing block are located inside the protruding opening. One end of the pressing rod is hinged to the fixing block, and the end of the fixing block away from the pressing rod is rotatably connected to the first door panel body.

[0014] Preferably, the firing assembly includes a pair of transverse slide rods and a sliding plate, a pair of impact blades are slidably connected between the pair of transverse slide rods, a pair of electrically operated telescopic rods are fixedly connected between the impact blades, and a second spring is fixedly connected to the end of the sliding plate away from the push block.

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

[0017] This invention improves the overall stability and fire resistance of the door panel by setting up a combination of structures such as a first door panel assembly and a second door panel assembly. By setting up a first door panel body and a second door panel body, multiple buffer spaces are provided. In the event of a fire, the overall temperature of the door body will not rise synchronously, but will gradually increase from the second door panel body to the first door panel body. At the same time, when the door panel is violently damaged, the second door panel body will be damaged first, while the first door panel body remains intact and can still play a role in preventing theft.

[0018] This invention facilitates the fixing of the first door panel body to the door frame by setting up a fixing component and other structures, thereby enhancing the stability and fire resistance of the door panel. The support frame pushes the sliding connecting rod to move on both sides, and at the same time, the push rod drives the pressing rod of the fixing connecting rod to move. The pressing rod pushes the fixing block to flip, so that the fixing block enters the interior of the door frame, so that the door panel and the door frame can be firmly connected. Therefore, in the event of forced entry or fire, the door panel will not be damaged by impact or burning, which would prevent the slide rail from being damaged and the entire door panel from falling off.

[0019] This invention, through the combination of a heat-conducting metal fork and a firing assembly, ensures that the door panel remains locked to the door frame regardless of whether it is forcibly removed or subjected to fire. When the second door panel is intentionally damaged, it is pushed, causing it to move through a limiting linkage and press a switch, thereby activating the electric telescopic rod. The electric telescopic rod then pushes the impact blade to both sides, causing it to impact and damage the plastic connector. When the second door panel is heated by flames, the heat-conducting metal fork on the inside of the second door panel directs the heat to the plastic connector, causing it to melt. This ensures that the plastic connector is damaged and broken by the support frame, regardless of whether it is forcibly removed or subjected to fire, thus locking the door panel to the door frame.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figures 1 to 9 As shown, the present invention provides a fireproof and anti-theft security dual-purpose door for ships, including a door frame 1 and a wall 10. A slide rail 2 is fixedly connected to the side of the door frame 1. A first door panel assembly 3 is slidably connected inside the slide rail 2. A second door panel assembly 4 is movably connected inside the first door panel assembly 3. A fixing component 6 is provided inside the first door panel assembly 3. A firing component 7 is movably connected to the middle of the first door panel assembly 3. A plastic connector 9 is fixedly connected between the pair of fixing components 6.

[0032] The first door panel assembly 3 includes a first door panel body 31, a partition plate 32 fixedly connected to the middle of the first door panel body 31, a middle slide rail 33 opened in the middle of the first door panel body 31, an extension opening 34 and a vertical slide groove 35 opened at the upper and lower ends of the first door panel assembly 3, and a pair of vertical slide rods 36 fixedly connected inside the first door panel body 31.

[0033] Using the above scheme: When the second door panel body 41 is squeezed and moved, the second door panel body 41 pushes the limit linkage 42 to move and squeeze the pressure switch 11, causing the pressure switch 11 to activate the electric telescopic rod 73. Then the electric telescopic rod 73 pushes the impact blade 72 to move to both sides, causing the impact blade 72 to impact the plastic connector 9, causing the plastic connector 9 to be damaged and pulled off by the support frame 61. Then the support frame 61 is pushed by the first spring 62 to slide up and down to both sides. The support frame 61 pushes the flipping rod of the sliding linkage 63 to move, so that the flipping rod can push the push rod to move to both sides by tilting and flipping. Simultaneously, it drives the squeezing rod of the fixed linkage 64 to push the fixed block to flip, so that the fixed block enters the interior of the door frame 1, completing the locking between the first door panel body 31 and the door frame 1.

[0034] like Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown, the door frame 1 is fixedly connected to the inside of the wall 10. A hydraulic telescopic rod 5 is fixedly connected to the middle of the slide rail 2. A fixing hole is opened on the side of the slide rail 2 away from the hydraulic telescopic rod 5. A push block 8 is fixedly connected to the output end of the hydraulic telescopic rod 5. The push block 8 is slidably connected to the first door panel body 31 and extends into the inside of the first door panel body 31. A pressure switch 11 is linearly distributed inside the first door panel body 31. A fireproof filling layer 12 is fixedly connected between the partition plate 32 and the second door panel assembly 4.

[0035] The above solution is adopted as follows: the hydraulic telescopic rod 5 set in the middle of the slide rail 2 can drive the first door panel body 31 to slide horizontally through the push block 8 at the output end of the hydraulic telescopic rod 5. The fixing hole opened on the side of the slide rail 2 can fix the first door panel body 31. The push block 8 is set to extend into the interior of the first door panel body 31, and can be moved by the push block 8 pressing the sliding plate 74. By setting the pressure switch 11, it can be pressed by the limiting link 42 when the second door panel body 41 is damaged and moves. The setting of the fireproof filling layer 12 can ensure the fireproof performance of the first door panel assembly 3 and the second door panel assembly 4.

[0036] like Figure 3 , Figure 6 and Figure 9As shown, the first door panel body 31 is slidably connected to the inside of the slide rail 2. A protrusion matching the fixing hole on the slide rail 2 is provided on the side of the first door panel body 31 away from the hydraulic telescopic rod 5. The end of the middle slide rail 33 near the push block 8 is connected to the inside of the first door panel body 31. The second door panel assembly 4 includes a second door panel body 41. Limiting rods 42 are linearly distributed near the first door panel body 31 on the second door panel body 41. Rigid springs 43 surround the end of each limiting rod 42 near the first door panel body 31. A pair of heat-conducting metal rods are fixedly connected to the middle of the second door panel body 41. The second door panel body 41 is movably connected to the inside of the first door panel body 31. The limiting link 42 extends through the fireproof filling layer 12 and the partition plate 32 to the inside of the first door panel body 31. The rigid spring 43 is located inside the first door panel body 31 and is fixedly connected to the first door panel body 31. The limiting link 42 corresponds to the position of the pressure switch 11. The pressure switch 11 is located inside the rigid spring 43. The heat-conducting metal fork 44 extends through the fireproof filling layer 12 and the partition plate 32 to the inside of the middle slide rail 33. The heat-conducting metal fork 44 contacts the plastic connector 9.

[0037] The above solution employs a protrusion on the side of the first door panel body 31 to facilitate its insertion into the fixing hole on the side of the slide rail 2 after it moves to the door frame 1, thus fixing the first door panel body 31. This connects the middle slide rail 33 to the interior of the first door panel body 31, allowing the sliding plate 74 to slide out from inside the middle slide rail 33. The second door panel assembly 4 can block flames and smoke in the event of a fire on one side of the second door panel assembly 4. By setting the second door panel body 41, the first door panel body 31 is prevented from being forcibly damaged or burned by flames before being blocked by the second door panel body 31. At this time, the first door panel body 31 can maintain a tight seal with the door frame 1. The limiting link 42 and rigid spring 43 provided on the side of the second door panel body 41 can support the second door panel body 41, so that after the second door panel body 41 is closed normally, people can lean on and pat it normally without the second door panel body 41 moving. A pair of heat-conducting metal forks 44 fixedly connected in the middle of the second door panel body 41 can conduct the temperature of the second door panel body 41 to the plastic connector 9 when the second door panel body 41 is burned by flame, so that the plastic connector 9 is partially melted by heat, and the supporting performance of the plastic connector 9 is reduced.

[0038] like Figure 3 , Figure 4 , Figure 5 and Figure 9As shown, the fixing component 6 includes a pair of support frames 61. A first spring 62 is fixedly connected to both ends of the pair of support frames 61. A pair of sliding connecting rods 63 are hinged to the side of the pair of support frames 61 that is far from each other. A fixed connecting rod 64 is rotatably connected to the end of the sliding connecting rod 63 that is far from the support frame 61. The ends of the support frames 61 that are close to each other are slidably connected inside the middle slide rail 33. The support frame 61 is slidably connected to the vertical slide rod 36. The first spring 62 surrounds the middle of the vertical slide rod 36. The first spring 62 is fixedly connected to the first door panel body 31. A fixing slot is opened at the end of the support frame 61 located inside the middle slide rail 33.

[0039] The above solution is adopted: by setting the fixing component 6, when the second door panel body 41 is damaged by human intervention or burned by fire, after the plastic connector 9 is disconnected, the first door panel body 31 and the door frame 1 are locked together, preventing the theft or burning of items on the first door panel body 31. After the plastic connector 9 is disconnected, the support frame 61 is pushed by the first spring 62 to slide up and down to both sides. The support frame 61 presses the sliding connecting rod 63, causing the sliding connecting rod 63 to drive the fixed connecting rod 64 to open to both sides, so that the fixed connecting rod 64 is locked with the door frame 1. The fixed connecting rod 64 locks the first door panel body 31 and the door frame 1, preventing the first door panel body 31 from being directly damaged and opened by personnel, or preventing flames and thick smoke from entering the room behind the first door panel body 31 through the gap between the first door panel body 31 and the door frame 1.

[0040] like Figure 3 , Figure 4 , Figure 5 and Figure 9 As shown, the sliding link 63 is divided into two parts: a flipping rod and a push rod. The flipping rod is located between the support frame 61 and the push rod, and its two ends are hinged to the support frame 61 and the push rod, respectively. The push rod is slidably connected inside the vertical slide groove 35 and is rotatably connected to the fixed link 64. The fixed link 64 is divided into two parts: a pressing rod and a fixed locking block. Both the pressing rod and the fixed locking block are located inside the protruding opening 34, and one end of the pressing rod is hinged to the fixed locking block. The end of the fixed locking block away from the pressing rod is rotatably connected to the first door panel body 31.

[0041] The above solution is adopted: the sliding link 63 is divided into two parts, and the flipping rod is pushed to move by the support frame 61, so that the flipping rod can push the push rod to move to both sides by tilting and flipping. At the same time, the push rod will drive the pressing rod of the fixed link 64 to move, and the pressing rod will push the fixed block to flip, so that the fixed block enters the interior of the door frame 1, and fixes the first door panel body 31 and the door frame 1.

[0042] like Figure 6 , Figure 7 and Figure 8As shown, the firing assembly 7 includes a pair of transverse slide rods 71 ​​and a sliding plate 74. A pair of impact blades 72 are slidably connected between the pair of transverse slide rods 71. A pair of electric telescopic rods 73 are fixedly connected between the impact blades 72. A second spring 75 is fixedly connected to the end of the sliding plate 74 away from the push block 8. The transverse slide rods 71 ​​are located between a pair of heat-conducting metal forks 44. The blades of the impact blades 72 face to both sides and abut against the plastic connectors 9. The electric telescopic rods 73 are connected to the pressure switch 11 through the power transmission line. The sliding plate 74 is slidably connected inside the middle slide rail 33. One end of the sliding plate 74 abuts against the push block 8. The sliding plate 74 is slidably connected to the fixed latch of the support frame 61 located inside the middle slide rail 33.

[0043] The above solution is adopted as follows: By setting the firing assembly 7, the impact head 72 is limited by the transverse slide bar 71. The impact head 72 can impact the plastic connector 9, damaging it and causing it to be pulled off by the support frame 61. The electric telescopic rod 73 set between the impact heads 72 can push the impact head 72 to slide to both sides, impacting the plastic connector 9. The electric telescopic rod 73 is connected to the pressure switch 11 through the power transmission line, so that when the second door panel body 41 is damaged, the electric telescopic rod 73 can be activated by the pressure switch 11. There is no force support point on the outer side of the second door panel body 41. Human damage to the second door panel body 41 will push the second door panel body 41 towards the partition plate 32, causing the second door panel body 41 to push the limit linkage 42 to press the pressure switch 11, thereby activating the electric telescopic rod 73. By setting the sliding plate 74 and the second spring 75, after the first door panel body 31 slides open, the pushing block 8 does not press the sliding plate 74, so that the sliding plate 74 will enter the opening on the support frame 61 and lock the support frame 61.

[0044] The working principle and usage process of this invention are as follows: When the second door panel body 41 is intentionally damaged, the damage will push the second door panel body 41 towards the partition plate 32, causing the second door panel body 41 to push the limiting linkage 42 to move and squeeze the pressure switch 11, causing the pressure switch 11 to activate the electric telescopic rod 73. Then, the electric telescopic rod 73 pushes the impact blade head 72 to move to both sides, causing the impact blade head 72 to impact the plastic connector 9, damaging the plastic connector 9. Then, the plastic connector 9 is pulled off by the support frame 61. When the plastic connector 9 is disconnected, the support frame 61 is pushed by the first spring 62 to slide up and down to both sides. The support frame 61 pushes the flipping rod to move, so that the flipping rod can push the push rod to move to both sides by tilting and flipping. At the same time, the push rod will drive the pressing rod of the fixed connecting rod 64 to move. The pressing rod pushes the fixed block to flip, so that the fixed block enters the interior of the door frame 1, fixing the first door panel body 31 and the door frame 1. This tightly connects the first door panel body 31 to the door frame 1, preventing the first door panel body 31 from being removed from the slide rail 2.

[0045] When a fire occurs on one side of the second door panel body 41, the second door panel body 41 is heated by the flames. The heat is then directed by the heat-conducting metal fork 44 on the inside of the second door panel body 41 to the plastic connector 9, causing the plastic connector 9 to melt and be broken by the support frame 61. The above steps will then be repeated to ensure that the first door panel body 31 is tightly connected to the door frame 1, preventing the leakage of flames and dense smoke.

[0046] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
