Description

Technical Field

[0001] The invention belongs to the technical field of safety doors, in particular to a ship-used fireproof and theft-proof safety dual-purpose door. Background Art

[0002] A door is an opening for people or objects to enter and exit, and is usually composed of door frames, door leaves, door locks and other parts. There are many types of doors, such as sensor doors, fire doors, anti-theft 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, the door can be closed to prevent important items from being stolen.

[0003] On board a ship, since the interior of the ship's hull is divided into multiple areas, each area requires different prevention, so different doors are generally used in a targeted manner. Traditional doors have relatively single functions, and even if they have other effects, they cannot take into account all of them. In addition, there are various types of doors on board, such as sliding doors. This type of door can provide better sealing and has a better sealing effect for fire prevention. However, since the door panel is fixed by a slide rail on the outside of the door frame, the overall safety and stability are low. At the same time, generally, this type of door has a single-layer door panel with fireproof materials filled inside. This causes the temperature of the door panel to directly rise as a whole when a fire occurs, causing the door panel to easily conduct heat and directly damage the slide rail.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention facilitates improving the overall stability and fire resistance of the door panel by arranging the cooperation of the first door panel assembly and the second door panel assembly. By arranging the first door panel body and the second door panel body, it is possible to have a multi-layer buffer space. When a fire occurs, the overall temperature of the door body will not rise synchronously, but the temperature will gradually rise from the second door panel body to the first door panel body.

[0035] The above scheme is adopted: by setting the hydraulic telescopic rod 5 in the middle of the slide rail 2, the pushing block 8 at the output end of the hydraulic telescopic rod 5 can drive the first door panel body 31 to slide horizontally, and the fixing hole opened on the side of the slide rail 2 can fix the first door panel body 31. The pushing block 8 is set to extend to the inside of the first door panel body 31, and the sliding card plate 74 can be squeezed by the pushing block 8 to move. By setting the push switch 11, when the second door panel body 41 is damaged and moves, it can be squeezed by the limit connecting rod 42. 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 Fig. 9As shown, the first door panel body 31 is slidably connected to the inside of the slide rail 2, and a protrusion block matching the fixing hole on the slide rail 2 is arranged on the side of the first door panel body 31 away from the hydraulic telescopic rod 5. The end of the middle slideway 33 close to the pushing 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. The second door panel body 41 is linearly distributed with a limiting connecting rod 42 close to the first door panel body 31. The limiting connecting rod 42 is surrounded by a rigid spring 43 at one end close to the first door panel body 31. A pair of heat conductive metals 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 limit link 42 passes through the fireproof filling layer 12 and the partition plate 32 and extends 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 limit link 42 corresponds to the position of the push switch 11, the push switch 11 is located on the inner side of the rigid spring 43, the heat-conducting metal fork 44 passes through the fireproof filling layer 12 and the partition plate 32 and extends to the inside of the middle slide 33, and the heat-conducting metal fork 44 contacts with the plastic connector 9.

[0037] The above scheme is adopted: the raised block arranged on the side of the first door panel body 31 facilitates the first door panel body 31 to be inserted into the fixing hole on the side of the slide rail 2 after being moved to the door frame 1, and the first door panel body 31 is fixed, and the middle slide 33 is connected with the inside of the first door panel body 31, so that the sliding card 74 can slide out from the inside of the middle slide 33. The setting of the second door panel assembly 4 can block the flame and smoke when a fire occurs on one side of the second door panel assembly 4. By setting the second door panel body 41, the first door panel body 31 can be blocked by the second door panel body 41 before it is forcibly destroyed by humans or burned by flames. At this time, the first door panel body 31 can maintain a tight seal with the door frame 1, and the second door panel body 41 can be supported by the limit link 42 and the rigid spring 43 arranged on the side of the second door panel body 41, so that after the second door panel body 41 is normally closed, people can lean on and pat it normally without moving the second door panel body 41. 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 flames, so that a part of the plastic connector 9 is melted by heat, thereby reducing the supporting performance of the plastic connector 9.

[0038] like Figure 3 , Figure 4 , Figure 5 and Fig. 9As shown, the fixing assembly 6 includes a pair of support frames 61, and the left and right ends of the pair of support frames 61 are fixedly connected with a first spring 62. The side of the pair of support frames 61 away from each other is hinged with a pair of sliding links 63, and the end of the sliding link 63 away from the support frame 61 is rotatably connected with a fixed link 64, and the ends of the support frames 61 close to each other are slidably connected to the inside of the middle slide 33, the support frame 61 is slidably connected to the vertical slide bar 36, the first spring 62 surrounds the middle part of the vertical slide bar 36, the first spring 62 is fixedly connected to the first door panel body 31, and the end of the support frame 61 located inside the middle slide 33 is provided with a fixed bayonet.

[0039] The above scheme is adopted: by setting the fixing component 6, when the second door panel body 41 is damaged by humans or burned by fire, after the plastic connecting piece 9 is disconnected, the first door panel body 31 and the door frame 1 are fastened to prevent the items in the first door panel body 31 from being stolen or burned by fire. After the plastic connecting piece 9 is disconnected, the support frame 61 is pushed by the first spring 62 to slide to the upper and lower sides, and the sliding connecting rod 63 is squeezed by the support frame 61, so that the sliding connecting rod 63 drives the fixing connecting rod 64 to open to both sides, so that the fixing connecting rod 64 is engaged and locked with the door frame 1, and the first door panel body 31 and the door frame 1 are locked by the fixing connecting rod 64 to prevent the first door panel body 31 from being directly damaged and opened by people, or 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 Fig. 9 As shown, the sliding link 63 is composed of two parts, a flip rod and a push rod, wherein the flip rod is located between the support frame 61 and the push rod, and both ends are hinged to the support frame 61 and the push rod respectively, wherein the push rod is slidably connected inside the vertical slide groove 35, and the push rod is rotatably connected to the fixed link 64, and the fixed link 64 is divided into two parts, an extrusion rod and a fixed block, wherein the extrusion rod and the fixed block are both located inside the protruding opening 34, and one end of the extrusion rod is hinged to the fixed block, wherein the end of the fixed block away from the extrusion rod is rotatably connected to the first door panel body 31.

[0041] The above scheme is adopted: the sliding connecting rod 63 is divided into two parts, and the flip rod is pushed to move by the support frame 61, so that the flip 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 extrusion rod of the fixed connecting rod 64 to move, and the extrusion 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 bars 71 and a sliding card plate 74, a pair of impact blade heads 72 are slidably connected between the pair of transverse slide bars 71, a pair of electric telescopic rods 73 are fixedly connected between the impact blade heads 72, and a second spring 75 is fixedly connected to one end of the sliding card plate 74 away from the pushing block 8. The transverse slide bar 71 is located between a pair of heat-conducting metal forks 44, the blades of the impact blade heads 72 face both sides and are in conflict with the plastic connector 9, the electric telescopic rod 73 is connected to the push switch 11 through the power transmission line, the sliding card plate 74 is slidably connected inside the middle slide 33, one end of the sliding card plate 74 is in conflict with the pushing block 8, and the sliding card plate 74 is slidably connected to the fixed card slot of the support frame 61 at one end inside the middle slide 33.

[0043] The above scheme is adopted: by setting the firing assembly 7, the impact blade head 72 is limited by the horizontal sliding rod 71, and the impact blade head 72 is set so that the impact blade head 72 can impact the plastic connecting member 9, damage the plastic connecting member 9, and make the plastic connecting member 9 be broken by the support frame 61. The electric telescopic rod 73 set between the impact blade heads 72 can push the impact blade head 72 to slide to both sides and impact the plastic connecting member 9. The electric telescopic rod 73 is connected to the push switch 11 through the power transmission line, so that when the second door panel body 41 is damaged, There is no force fulcrum 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 toward the side of the partition plate 32, so that the second door panel body 41 pushes the limit link 42 to squeeze the pressing switch 11, thereby starting the electric telescopic rod 73. By setting a sliding card plate 74 and a second spring 75, after the first door panel body 31 slides open, the pushing block 8 does not squeeze the sliding card plate 74, so that the sliding card plate 74 will enter the opening opened on the support frame 61, thereby locking the support frame 61.

[0044] The working principle and use process of the present invention are as follows: when the second door panel body 41 is damaged artificially, the artificial damage to the second door panel body 41 will push the second door panel body 41 toward the side of the partition plate 32, so that the second door panel body 41 pushes the limit link 42 to move and squeeze the pressure switch 11, so that the pressure switch 11 activates the electric telescopic rod 73, and then the electric telescopic rod 73 pushes the impact blade 72 to move to both sides, so that the impact blade 72 impacts the plastic connector 9, so that the plastic connector 9 is damaged, and then the plastic connector 9 is pulled and broken by the support frame 61. After the plastic connector 9 is disconnected, the support frame 61 is pushed by the first spring 62 to slide upward and downward, and the support frame 61 pushes the flip rod to move, so that the flip rod can push the push rod to move to both sides by tilting and flipping. At the same time, the push rod drives the extrusion rod of the fixed link 64 to move, and the extrusion rod pushes the fixed block to flip, so that the fixed block enters the interior of the door frame 1, fixes the first door panel body 31 and the door frame 1, so as to tightly connect the first door panel body 31 and the door frame 1, and prevent the first door panel body 31 from being removed from the slide rail 2 as a whole;

[0045] When a fire occurs on one side of the second door panel body 41, the second door panel body 41 is heated up by the flame, and the heat-conducting metal fork 44 on the inner side of the second door panel body 41 conducts the heat to the plastic connector 9, causing the plastic connector 9 to melt due to the heat and be pulled apart by the support frame 61. The above steps are then repeated to tightly connect the first door panel body 31 to the door frame 1 to prevent leakage of flame and smoke.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

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