Description

A fireproof sealing device for small-opening rectangular track logistics Technical Field

[0001] This utility model provides a fireproof sealing device for small-opening rectangular track logistics, belonging to the technical field of building fire protection equipment. Background Technology

[0002] Holes are a common architectural feature in various buildings and structures, especially in buildings that require frequent material transport, such as logistics warehouses and automated production lines. These holes facilitate the transport of materials within partitioned spaces, particularly when using tracked trolleys to transport precision components, chips, and high-value-added items, significantly improving production efficiency and safety.

[0003] However, in terms of building fire prevention, the existence of building openings undoubtedly provides a convenient route for fire to spread to adjacent spaces in the event of a fire. Therefore, fireproofing building openings is crucial for achieving building fire safety. Because building openings serve different purposes, their shape, size, location, and whether objects pass through them vary considerably. Fireproofing building openings without penetrating objects is relatively easy, but fireproofing openings with penetrating objects has always been a technical challenge, especially with dynamic penetrating objects, such as material transport trolleys.

[0004] Therefore, in view of this, we studied and improved the existing structure and proposed a fireproof sealing device for small-opening rectangular track logistics to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem this invention aims to solve is that traditional fireproof sealing devices for small-opening rectangular track logistics systems cannot meet the special requirements of such systems.

[0006] In order to solve the above problems, the present invention proposes the following technical solution: The present invention provides a fireproof sealing device for small-opening rectangular track logistics, including a frame, a fireproof sealing plate, an embedded split fire-arresting mechanism, an embedded split fire-arresting mechanism operating mechanism, and a flip plate base. The frame is installed on the wall on the fire-resistant side of the building opening, and the frame is provided with a slide rail for guiding the movement of the fireproof sealing plate.

[0007] The fireproof sealing plate includes a steel plate, a ceramic fiber board, paper, rock wool, fire-resistant tape, and an overflow hole;

[0008] The embedded split fire arrestor mechanism includes a telescopic fire arrestor block, a U-shaped telescopic positioning bracket, a U-shaped telescopic positioning shaft, a support arm, an S-shaped base plate, a guide post, a compression spring, a guide groove, an S-shaped base plate rotating shaft, a guide shaft, a double-sided open overflow hole sleeve plate, an outer cover, a base plate, a double U-shaped telescopic fire arrestor block positioning sleeve, and a bushing.

[0009] The embedded split fire arrestor mechanism includes a fixed corner plate, a force-bearing corner plate, a corner plate, a corner spring, a rotating wheel, and an outer cover.

[0010] Furthermore, one side of the frame is also provided with a single-sided figure-eight guide rail, and a positioning universal wheel is provided at the top of the single-sided figure-eight guide rail.

[0011] Furthermore, the fireproof sealing plate, through the engagement of the guide wheel and the slide rail, can move along the slide rail under the drive of the electric push rod to realize the opening and closing of the building opening. When the fireproof sealing plate moves from below the small opening rectangular track to the single-sided small opening rectangular track on the upper left, it can re-enter the track by means of the single-sided figure-eight guide rail.

[0012] Furthermore, the bottom of the double U-shaped telescopic fire arrestor block positioning sleeve is provided with a base plate, and guide posts are provided on both sides. The upright plate of the double U-shaped telescopic fire arrestor block positioning sleeve between the guide posts is provided with a guide groove. A compression spring is sleeved on the guide post. The S-shaped base plate presses the compression spring into the guide post through the double holes in the middle. The guide shaft at the front end of the S-shaped base plate is hinged to the two arms. The two sides of the arms are positioned by the bushings to extend outward. The other ends of the two arms are respectively hinged to the U-shaped telescopic positioning bracket, the U-shaped telescopic positioning shaft and the telescopic fire arrestor block. The combined double U-shaped telescopic fire arrestor block positioning sleeve is placed in the double-sided opening overflow hole sleeve plate and fixed. The S-shaped base plate is fixed to the fireproof sealing plate or the stress-bearing corner plate, and the outer cover is fastened on it. The upper end of the outer cover is provided with an outward-facing eave.

[0013] Furthermore, the fixed corner plate is fixed to the fireproof sealing plate and is axially connected to the force-bearing corner plate through the corner plate. The front end of the force-bearing corner plate is provided with a rotating wheel and an L-bend. The corner spring is connected between the fixed corner plate and the force-bearing corner plate at a reverse angle. The force-bearing corner plate is welded to the embedded split fire-resistant mechanism as a whole.

[0014] Furthermore, the flap base is fixed to the wall on the underside of the unexposed side of the building opening, and is hinged to the fireproof sealing plate via a hinge. The rear end fixing seat of the electric push rod is fixed to the flap base, and the front end fixing seat is fixed to the fireproof sealing plate.

[0015] Furthermore, when the overflow holes on the fireproof sealing plate, the corresponding wall surface, the small-opening rectangular track, and the telescopic fire arrestor block are heated, they can expand and overflow the fire-arresting tape. The double-sided opening overflow hole sleeve is located on the contact surface of the small-opening rectangular track, which allows the fire-arresting tape that expands and overflows from the telescopic fire arrestor block to overflow twice through its overflow hole onto the contact surface of the small-opening rectangular track. The guide wheels, the embedded split fire arrestor mechanism, and the outer cover on the fireproof sealing plate are all set in multiple sets.

[0016] Furthermore, when the slide rail of the frame is set vertically, the fireproof sealing plate is fitted with guide wheels at the top and bottom. Under the action of the electric push rod, the fireproof sealing plate moves left and right along the running slide rail to close or open the building opening. After the fireproof sealing plate extends through the small-opening rectangular track, it is guided by the single-sided figure-eight guide rail and its top positioning universal wheel to slide into the single-sided figure-eight guide rail groove.

[0017] Furthermore, when the slide rails of the frame are set on the left and right, the fireproof sealing plate is fitted with guide wheels on the left and right. Under the action of the electric push rod, the fireproof sealing plate moves up and down along the running slide rail to close or open the building opening. The embedded split fire-resistant mechanism enters the small opening rectangular track opening from the small opening rectangular track opening under the push of the electric push rod.

[0018] Furthermore, when the embedded split fire arresting mechanism, fixed to the fireproof sealing plate, slowly enters the small-opening rectangular track opening under the action of the push rod and rests on the small-opening rectangular track, the double-sided overflow hole sleeve plate at the front end of the embedded split fire arresting mechanism rests on the small-opening rectangular track under the continued action of the push rod. The S-shaped base plate is stressed and compresses the compression spring. The compression spring on the base plate guide post is compressed around the guide post. The guide shaft at the front end of the S-shaped base plate slides in the guide groove. The guide shaft is also connected to the support arm. The support arm is provided with bushings on both sides to position the support arm. In the outward direction, both ends of the support arm are hinged to the U-shaped telescopic positioning shaft on the U-shaped telescopic positioning bracket on the telescopic fire arrestor block. The telescopic fire arrestor block continues to be pushed by the push rod, causing the double-opening overflow hole sleeve plate to press against the small-opening rectangular track and continue to be stressed. This causes the guide shaft on the S-shaped base plate to extend along the guide groove toward the small-opening rectangular track. The support arm on the guide shaft causes the telescopic fire arrestor block to be positioned up, down, left, and right along the double-U-shaped telescopic fire arrestor block positioning sleeve and the double-opening overflow hole sleeve plate. The side arms of the small-opening rectangular track on both sides extend to their limit positions, and the electric push rod stops working.

[0019] Furthermore, when the space is too small to set up a frame, the flip-up base is fixed to the wall on the side of the unexposed side of the building opening and is hinged to the fireproof sealing plate. The rear end fixing seat of the electric push rod is fixed to the flip-up base, and the front end fixing seat is fixed to the fireproof sealing plate. The fireproof sealing plate flips along an arc-shaped trajectory. When it flips to the point where the embedded split fire-arresting mechanism approaches the small-opening rectangular track, the telescopic fire-arresting block is restricted by the arc-shaped trajectory and enters the small-opening rectangular track in a polygonal shape at the rear end of the flipped direction, adapting to the flipping angle of the small-opening rectangular track.

[0020] Furthermore, when the fireproof sealing plate flips along an arc-shaped trajectory on its fire-facing surface, under the action of the electric push rod, when it flips to the point where the embedded split fire-arresting mechanism approaches the small-opening rectangular track, the telescopic fire-arresting block is restricted by the arc-shaped trajectory and enters the small-opening rectangular track in a polygonal shape at the rear end of the flipped direction.

[0021] Due to the adoption of the above technical solution, the beneficial effects of this utility model of a fireproof sealing device for small-opening rectangular track logistics are as follows:

[0022] 1. This utility model's fire-stopping device, through a specially designed frame, fire-stopping plate, embedded split fire-arresting mechanism, and its operating mechanism, can effectively fire-stop building openings through which small-opening rectangular track logistics systems pass. In the event of a fire, the fire-stopping plate can quickly close the building opening, and the embedded split fire-arresting mechanism can further penetrate into the track opening for sealing. The fire-arresting tape expands and overflows when heated, enhancing the sealing effect and preventing the spread of fire.

[0023] 2. The single-sided figure-eight guide rail and positioning casters facilitate the movement of the fireproof sealing plate within the rail, improving the ease of operation of the device. Different rail configurations and the methods for moving and flipping the fireproof sealing plate adapt to various installation scenarios, demonstrating good versatility. Attached Figure Description

[0052] Please refer to Figures 1-13: This utility model provides a fireproof sealing device for small-opening rectangular track logistics: including a frame 20, a fireproof sealing plate 30, an embedded split fire-arresting mechanism 40, an embedded split fire-arresting mechanism operating mechanism 50, and a flip-plate base 60. The frame 20 is installed on the wall 101 on the side of the unexposed surface 103 of the building opening 10, and the frame 20 is provided with a slide rail 201 for guiding the movement of the fireproof sealing plate 30.

[0053] The fireproof sealing plate 30 includes a steel plate 301, a ceramic fiber board, paper 302, rock wool 303, fire-resistant wrapping tape 304, and an overflow hole 305.

[0054] The embedded split fire arrestor mechanism 40 includes a telescopic fire arrestor block 401, a U-shaped telescopic positioning bracket 4011, a U-shaped telescopic positioning shaft 4012, a support arm 4013, an S-shaped base plate 402, a guide post 4021, a compression spring 4022, a guide groove 4023, an S-shaped base plate rotating shaft 4024, a guide shaft 4025, a double-sided open overflow hole sleeve plate 4026, an outer cover 4027, a base plate 4028, a double U-shaped telescopic fire arrestor block positioning sleeve 4029, and a bushing 4030.

[0055] The embedded split fire arrestor mechanism operating mechanism 50 includes a fixed corner plate 501, a force-bearing corner plate 502, a corner plate 503, a corner spring 504, a rotating wheel 505, and an outer cover 4027.

[0056] The frame 20 is also provided with a single-sided figure-eight guide rail 202 on one side, and a positioning universal wheel 203 is provided on the top of the single-sided figure-eight guide rail 202.

[0057] The fireproof sealing plate 30 is connected to the slide rail 201 by the inlaid guide wheel 306. Driven by the electric push rod 204, it can move along the slide rail 201 to open and close the building opening 10. When the fireproof sealing plate 30 moves from below the small opening rectangular track 104 to the single-sided small opening rectangular track 104 on the upper left, it can re-enter the track by means of the single-sided figure-eight guide rail 202.

[0058] The bottom of the double U-shaped telescopic fire arrester block positioning sleeve 4029 is provided with a base plate 4028, and guide posts 4021 are provided on both sides. The upright plate of the double U-shaped telescopic fire arrester block positioning sleeve 4029 between the guide posts 4021 is provided with a guide groove 4023. A compression spring 4022 is sleeved on the guide post 4021. The S-shaped base plate 402 presses the compression spring 4022 into the guide post 4021 through the double holes in the middle. The guide shaft 4025 at the front end of the S-shaped base plate 402 is hinged to the two support arms 4013. The side is positioned by the bushing 4030 in the outward direction. The other end of the two arms 4013 is respectively hinged to the U-shaped telescopic positioning bracket 4011, the U-shaped telescopic positioning shaft 4012 and the telescopic fire arresting block 401. The combined double U-shaped telescopic fire arresting block positioning sleeve 4029 is placed in the double-sided opening overflow hole sleeve plate 4026 and fixed. The S-shaped base plate 402 is fixed to the fireproof sealing plate 30 or the stress-bearing corner plate. The outer cover 4027 is fastened on it. The upper end of the outer cover 4027 is provided with an outward-facing eave.

[0059] The fixed corner plate 501 is fixed to the fireproof sealing plate 30 and is axially connected to the force-bearing corner plate 502 through the corner plate 503. The front end of the force-bearing corner plate 502 is provided with a rotating wheel 505 and an L-bend. The corner spring 504 is connected between the fixed corner plate 501 and the force-bearing corner plate 502 at opposite angles. The force-bearing corner plate 502 is welded to the embedded split fire-arresting mechanism 40 as a whole.

[0060] The flip-plate base 60 is fixed to the wall 101 on the lower side of the unexposed surface 103 of the building opening 10, and is hinged to the fireproof sealing plate 30 by a hinge 601. The rear end fixing seat 2041 of the electric push rod 204 is fixed to the flip-plate base 60, and the front end fixing seat 2042 is fixed to the fireproof sealing plate 30.

[0061] When the fireproof sealing plate 30 is heated, the overflow hole 305 on the wall surface 101, the small-opening rectangular track 104, and the telescopic fire arresting block 401 can expand and overflow the fire-arresting wrapping tape 304. The double-sided opening overflow hole sleeve plate 4026 is located on the contact surface of the small-opening rectangular track 104, which allows the fire-arresting wrapping tape 304 that expands and overflows in the telescopic fire arresting block 401 to overflow twice through its overflow hole 305 to the contact surface of the small-opening rectangular track 104. The guide wheel 306, the embedded split fire arresting mechanism 40, and the outer cover 4027 on the fireproof sealing plate 30 are all set in multiple sets.

[0062] When the slide rail 201 of the frame 20 is set vertically, the fireproof sealing plate 30 is fitted with guide wheels 306 vertically. Under the action of the electric push rod 204, the fireproof sealing plate 30 moves left and right along the running slide rail 201 to close or open the building opening 10. After the fireproof sealing plate 30 extends through the small-opening rectangular track 104, it is guided by the single-sided figure-eight guide rail 202 and its top positioning universal wheel 203, and slides into the groove of the single-sided figure-eight guide rail 202. When the slide rail 201 of the frame 20 is set horizontally, the fireproof sealing plate 30 is fitted with guide wheels 306 horizontally. Under the action of the electric push rod 204, the fireproof sealing plate 30 moves up and down along the running slide rail 201 to close or open the building opening 10. The embedded split fire arrestor mechanism 40, driven by the electric push rod 204, enters the small opening rectangular track 104 through the opening. When the space is too small to set up a frame, the flip plate base is fixed to the wall on the side of the unexposed side of the building opening and is hinged to the fireproof sealing plate. The rear end fixing seat of the electric push rod is fixed to the flip plate base, and the front end fixing seat is fixed to the fireproof sealing plate. The fireproof sealing plate flips along an arc-shaped trajectory. When the embedded split fire arrestor mechanism approaches the small opening rectangular track, the telescopic fire arrestor block is restricted by the arc-shaped trajectory and enters the small opening rectangular track in a polygonal shape at the rear end of the flipped direction, adapting to the flipping angle of the small opening rectangular track.

[0063] When the fireproof sealing plate 30 fire-facing surface 102 flips along an arc-shaped trajectory, under the action of the electric push rod 204, when the inlaid split fire-arresting mechanism 40 approaches the small-opening rectangular track 104, the telescopic fire-arresting block 401 is restricted by the arc-shaped trajectory, and enters the small-opening rectangular track 104 in a polygonal shape 4014 at the rear end facing the flipping direction.

[0064] The principle of this utility model for a fireproof sealing device for a small-opening rectangular track logistics system is as follows: First, the frame is installed on the wall on the unexposed side of the building opening, ensuring the frame is firmly installed and its slide rail is in the correct installation position. Depending on actual needs, if the slide rail is vertically set, the guide wheels of the subsequent fireproof sealing plate are engaged in the vertical position; if the slide rail is horizontally set, the guide wheels are engaged in the horizontal position. A single-sided figure-eight guide rail is installed on one side of the frame, and a positioning caster is installed on its top. The fireproof sealing plate is then installed, with the guide wheels on the fireproof sealing plate engaging with the slide rail of the frame, ensuring the fireproof sealing plate can move smoothly on the slide rail.

[0065] Install the embedded split fire arresting mechanism. The bottom of the double U-shaped telescopic fire arresting block positioning sleeve is set with a base plate, and guide posts are set on both sides. The guide post vertical plate is set with a guide groove. The guide post is fitted with a compression spring. The S-shaped base plate presses the compression spring into the guide post through the double holes in the middle. The guide shaft at the front end of the S-shaped base plate is hinged to the support arm. The two sides of the support arm are positioned by the bushings to extend outward. The other end of the two support arms is respectively hinged to the U-shaped telescopic positioning bracket, the U-shaped telescopic positioning shaft and the telescopic fire arresting block to assemble the embedded split fire arresting mechanism. The assembled double U-shaped telescopic fire arresting block positioning sleeve is placed in the double-sided opening overflow hole sleeve plate and fixed. The S-shaped base plate is fixed to the fireproof sealing plate or the stress corner plate. Finally, the outer cover is fastened.

[0066] Install the embedded split fire arrestor mechanism, fix the fixed corner plate to the fireproof sealing plate, and axially connect the corner plate and the load-bearing corner plate. Install a rotating wheel and an L-bend at the front end of the load-bearing corner plate, connect the corner spring at the opposite angle between the fixed corner plate and the load-bearing corner plate, and weld the load-bearing corner plate and the embedded split fire arrestor mechanism into one piece.

[0067] The flap base is fixed to the wall on the side of the building opening facing away from the fire, and is hinged to the fireproof sealing plate. An electric push rod is installed, and the rear end fixing seat of the electric push rod is fixed to the flap base, and the front end fixing seat is fixed to the fireproof sealing plate.

[0068] Under normal conditions, the fire-resistant sealing panel is in the open position, and the small-opening rectangular track logistics system operates normally. In the event of a fire, the electric push rod activates. If the frame's slide rails are vertically arranged, the electric push rod pushes the fire-resistant sealing panel to move left and right along the running slide rails, moving towards the building opening to close it. After the fire-resistant sealing panel extends through the small-opening rectangular track, it is guided by the single-sided figure-eight guide rail and its top positioning caster wheel, sliding into the single-sided figure-eight guide rail groove to complete the closing action. The fireproof sealing plate 30's upper and lower guide rails 306, under the action of the extended electric push rod 204, move to the left along the running slide rail 201 to close the building opening 10. After the fireproof sealing plate 30 passes through the small-opening rectangular track 104, it is slid into the groove of the single-sided figure-eight guide rail 202 and its top positioning universal wheel 203. The embedded split fire-arresting mechanism running mechanism 50, fixed on the fireproof sealing plate 30, rolls upward when the rotating wheel 505 contacts the left side frame of the frame 20 under the action of the push rod 204, driving the force-bearing corner plate 502 through the corner plate. 503 and the fixed corner plate 501 are axially driven, and the force-bearing corner plate 502 is welded together with the embedded split fire arrestor mechanism 40. At the same time, when the rotating wheel 505 rolls upward along the left side of the frame 20, the force-bearing corner plate 502 moves in an arc-shaped trajectory along the push rod 204 at a 90-degree angle under the cooperative action of the corner plate 503 and the outer cover 4027, sending the embedded split fire arrestor mechanism 40 into the small opening of the small opening rectangular track 104. At this time, under the continued action of the push rod 204, the double-sided opening overflow hole sleeve plate 4026 of the embedded split fire arrestor mechanism 40 rests on the small opening rectangular track 104, and the S-shaped base plate 402... The compression spring 4022 is compressed under force. The compression spring 4022 on the guide post 4021 of the base plate 4028 is compressed around the guide post 4021. The front end of the S-shaped base plate 402 has a guide shaft 4025 that slides in the guide groove 4023. The guide shaft 4025 is also connected to the support arm 4013. The support arm 4013 has bushings 4030 on both sides to position the support arm 4013 in the outward direction. The two ends of the support arm 4013 are respectively linked with the U-shaped telescopic positioning shaft 4012 on the U-shaped telescopic positioning bracket 4011 on the telescopic fire arrester block 401, so that the telescopic fire arrester block 401 continues to be pushed by the push rod 204, causing the overflow holes on both sides to overflow. The sleeve plate 4026 continues to bear force on the small-opening rectangular track 104, causing the guide shaft 4025 on the S-shaped base plate 402 to extend along the guide groove 4023 toward the small-opening rectangular track 104. The support arm 4013 on the guide shaft 4025 causes the telescopic fire arresting block 401 to be positioned up, down, left, and right along the double U-shaped telescopic fire arresting block positioning sleeve 4029 and the double-sided opening overflow hole sleeve plate 4026 welded together. The side arms of the small-opening rectangular track 104 on both sides extend to their limit positions, and the electric push rod 204 stops working, completely sealing the opening of the building hole 10 and the small-opening rectangular track 104.When the fireproof sealing plate 30 is heated, the overflow hole 305 on the corresponding wall surface 101, the corresponding small-opening rectangular track 104, and the telescopic fire arresting block 401 expands and overflows the fire-arresting wrapping tape 304, which completely seals the gaps on the wall surface corresponding to the fireproof sealing plate 30, the gaps on the contact surface of the small-opening rectangular track 104, and the gaps around the small-opening rectangular track 104 and the telescopic fire arresting block 401.

[0069] If the frame's slide rails are arranged horizontally, the electric push rod pushes the fireproof sealing plate to move up and down along the running slide rails to close the building openings. Simultaneously, the embedded split fire-arresting mechanism, pushed by the electric push rod, enters the small-opening rectangular track opening. When it reaches the small-opening rectangular track 104 opening, the embedded split fire-arresting mechanism 40, fixed to the fireproof sealing plate 30, slowly enters the small-opening rectangular track 104 opening under the action of the push rod 204 and presses against the small-opening rectangular track 104. At this time, under the continued action of the push rod 204, the double-sided overflow hole sleeve 4026 at the front end of the embedded split fire-arresting mechanism 40 presses against the small-opening rectangular track. On 104, the S-shaped base plate 402 compresses the compression spring 4022 under force. The compression spring 4022 on the guide post 4021 of the base plate 4028 is compressed around the guide post 4021. The guide shaft 4025 at the front end of the S-shaped base plate 402 slides in the guide groove 4023. The guide shaft 4025 is also connected to the support arm 4013. The support arm 4013 has bushings 4030 on both sides to position the support arm 4013 in the outward direction. The two ends of the support arm 4013 are respectively connected to the U-shaped telescopic positioning shaft 4 on the U-shaped telescopic positioning bracket 4011 on the telescopic fire arrester block 401. 012 Hinged, the telescopic fire arrestor block 401 continues to be pushed by the push rod 204, causing the double-sided opening overflow hole sleeve plate 4026 to press against the small-opening rectangular track 104. The continued force causes the guide shaft 4025 on the S-shaped base plate 402 to extend along the guide groove 4023 toward the small-opening rectangular track 104. The support arm 4013 on the guide shaft 4025 causes the telescopic fire arrestor block 401 to be positioned vertically, horizontally, and vertically along the double U-shaped telescopic fire arrestor block positioning sleeve 4029 and the double-sided opening overflow hole sleeve plate 4026, moving toward the small-opening rectangular track 104. When the side arms of the rectangular track 104 extend to their limit positions, the electric push rod 204 stops working, completely sealing the opening of the building hole 10 and the small-opening rectangular track 104; the overflow holes 305 on the corresponding wall surface 101, the corresponding small-opening rectangular track 104, and the telescopic fire arresting block 401 expand when heated, and the overflow fire arresting tape 304 completely seals the gaps on the wall surface corresponding to the fireproof sealing plate 30, the gaps on the contact surface of the small-opening rectangular track 104, and the gaps around the small-opening rectangular track 104 and the telescopic fire arresting block 401.

[0070] If the space is too small to install a frame, the electric push rod 204 extends. The push rod 204, fixed to the rear end fixing seat 2041 of the flip plate base 60, flips the fireproof sealing plate 30 towards the wall 101 via the hinge 601. This causes the embedded split fire-arresting mechanism 40 fixed to the fireproof sealing plate 30 to flip towards the corresponding position of the opening of the small-opening rectangular track 104. Under the action of the push rod 204, the fire-facing surface 102 of the fireproof sealing plate 30 flips along an arc-shaped trajectory. When the embedded split fire-arresting mechanism 40 flips to approach the small-opening rectangular track 104, the flipping track is constrained by the arc-shaped trajectory. The telescopic fire arrestor block 401, after being flipped, forms a polygonal shape at its rear end and enters the small-open rectangular track 104. At this time, under the continued action of the push rod 204, the U-shaped overflow hole sleeve 4026 at the front end of the embedded split fire arrestor mechanism 40 presses against the small-open rectangular track 104. The S-shaped base plate 402 is subjected to force, compressing the compression spring 4022. The compression spring 4022 on the guide post 4021 of the base plate 4028 is compressed around the guide post 4021. The guide shaft 4025 at the front end of the S-shaped base plate 402 slides in the guide groove 4023. At the same time, the guide shaft 4025 drives the support arm 4013 to extend the hinged support arms to both ends. The U-shaped telescopic positioning shaft 4012 on 4011 drives the telescopic fire arresting block 401 to extend to both ends. The telescopic fire arresting block 401, under the combined force of the support arm 4013, the S-shaped base plate 402, and the push rod 204, causes the double-sided opening overflow hole sleeve 4026 to press against the small-opening rectangular track 104. The force causes the guide shaft 4025 on the S-shaped base plate 402 to extend along the guide groove 4023 toward the small-opening rectangular track 104. The support arm 4013 on the guide shaft 4025 causes the telescopic fire arresting block 401 to extend along the double U-shaped telescopic fire arresting block positioning sleeve 4029 and the double-sided opening overflow hole sleeve welded together. 4026 Positions the telescopic fire arrestor block 401 vertically, horizontally, and vertically, and extends the side arms of the small-opening rectangular track 104 to their limit positions on both sides. At this time, it is rotated to 90 degrees to close the building opening 10, and the electric push rod 204 stops working. The overflow hole 305 on the wall surface 101, the small-opening rectangular track 104, and the telescopic fire arrestor block 401 of the fireproof sealing plate 30 expands and overflows the fire-arresting wrapping tape 304 to completely seal the gaps on the wall surface, the contact surface gaps of the small-opening rectangular track 104, and the gaps around the small-opening rectangular track 104 and the telescopic fire arrestor block 401.

[0071] During a fire, when the fire-stopping plate is heated, the fire-resistant tape expands and overflows from the overflow holes on the wall surface, the small-opening rectangular track, and the telescopic fire-arresting block. The double-sided overflow hole sleeve is located on the contact surface of the small-opening rectangular track, which allows the fire-arresting tape that has expanded and overflowed from the telescopic fire-arresting block to overflow a second time onto the contact surface of the small-opening rectangular track through its overflow hole, thereby enhancing the fire-stopping effect.

[0072] This utility model achieves efficient fireproof sealing through the installation of an embedded split fire-resistant mechanism and accessories, without affecting the normal operation of the rail logistics system.

[0073] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
