Description

Technical Field

[0001] This invention belongs to the field of fire protection equipment technology, and specifically relates to a novel fire box. Background Technology

[0002] Fire extinguisher boxes are essential core fire emergency facilities in high-risk locations such as airport aviation fuel storage and transportation and refined oil storage. They are mainly used to store fire extinguishers and related emergency fire-fighting equipment. They are a key basic component of the site's fire safety protection system. Their ease of access, explosion-proof safety performance, and structural durability directly determine the efficiency of fire emergency response and the overall fire safety guarantee capability of the site.

[0003] Currently, conventional fire extinguisher boxes used in oil depots, airport fuel stations, and other similar locations are mostly fixed, fully enclosed structures, typically using side-opening doors or top-hinged flaps. Fire extinguishers and other firefighting equipment are completely housed within the enclosed interior of the fixed box. However, through long-term field application and maintenance, these existing fire extinguisher boxes have gradually revealed several intractable technical defects and usage pain points, failing to meet the high standards of fire safety management required by oil depots. Existing fixed-structure fire extinguisher boxes require opening the door or flipping open the lid before reaching inside to retrieve the fire extinguisher. This cumbersome process can easily delay the best initial fire response time in the event of a sudden fire, highlighting a significant shortcoming in emergency response.

[0004] Existing conventional fire extinguisher boxes lack a dedicated explosion-proof design in their opening and closing mechanism. The opening and closing of the door or flap can easily generate metal-to-metal sparks and static electricity buildup. When used in locations with flammable and explosive vapors, such as aviation fuel depots and refined oil depots, this poses a significant fire and explosion hazard and fails to meet the explosion-proof safety management requirements for high-risk locations. Furthermore, existing fire extinguisher boxes generally suffer from poor workmanship, often constructed from ordinary thin steel plates. Prolonged outdoor use easily leads to rust, deformation, and structural damage, resulting in a short service life and frequent replacements, significantly increasing the fire safety maintenance costs of such locations. Summary of the Invention

[0005] In order to solve the technical problems of low emergency access efficiency and poor structural durability of fire boxes and fire extinguishers in existing technologies, this invention provides a new type of fire box.

[0006] The technical solution adopted in this invention is as follows: In a first aspect, the present invention provides a novel fire box, comprising at least one hollow box body with an open top, a base, a lifting shell, a flip cover, a slide rail, a lifting rod, and a top support rod; The bottom of the box is fixed to the base, and the outer wall of the box is provided with vertically extending slide rails; The lifting housing is a hollow structure that runs vertically through the body. The lifting housing is fitted onto the outside of the box body. The inner wall of the lifting housing is equipped with a slider that matches the slide rail. The lifting housing slides vertically and vertically along the axial direction of the box body through the cooperation of the slider and the slide rail. The flip cover is rotatably connected to the top of the lifting housing and is used to open and close the top opening of the lifting housing; the lifting rod is located inside the housing, and both ends of the lifting rod are connected to the housing and the lifting housing respectively. The lifting rod always applies an upward supporting force to the lifting housing; the lower end of the top support rod is fixed to the housing, and the upper end of the top support rod abuts against the inner end face of the flip cover. A linkage structure is provided between the flip cover and the lifting rod. When the flip cover changes from the closed state to the open state, the linkage structure triggers the lifting rod to reduce the upward supporting force, and the lifting housing slides down along the slide rail, exposing the fire-fighting equipment inside the box. When the flip cover changes from the open state to the closed state, the lifting rod resets and locks, the lifting housing remains in the high position, and the flip cover closes the top opening of the lifting housing.

[0007] In conjunction with the first aspect, the present invention provides a first embodiment of the first aspect, wherein at least two boxes are provided, and all boxes are symmetrically fixed on the base.

[0008] In conjunction with the first embodiment of the first aspect, the present invention provides a second embodiment of the first aspect, wherein the lifting housing is an integral structure, and the integral lifting housing is simultaneously fitted onto the outside of all the boxes, thereby driving all the corresponding housing parts to slide up and down synchronously.

[0009] In conjunction with the second embodiment of the first aspect, the present invention provides a third embodiment of the first aspect, wherein the flip cover is an integral structure, and the integral flip cover is simultaneously rotatably connected to the top of the integral lifting housing, and synchronously opens and closes the top openings of all lifting housings.

[0010] In conjunction with the first aspect, the present invention provides a fourth embodiment of the first aspect, wherein the lifting rod is a hydraulic support rod, the lower end of the hydraulic support rod is hinged to the inner bottom of the housing, and the upper end of the hydraulic support rod is hinged to the top of the inner wall of the lifting housing.

[0011] In conjunction with the first aspect, the present invention provides a fifth embodiment of the first aspect, wherein the two opposite outer side walls of the housing are provided with vertical slide rails, and the lifting housing is provided with a matching slider corresponding to the position of each slide rail.

[0012] In conjunction with the first aspect, the present invention provides a sixth embodiment of the first aspect, wherein the upper end of the top support rod is provided with an abutment portion, and during the opening of the flip cover, the abutment portion always slides against the inner end face of the flip cover, thereby limiting the opening angle of the flip cover and maintaining the open state of the flip cover.

[0013] In conjunction with the first aspect, the present invention provides a seventh embodiment of the first aspect, wherein a handle is fixed to the outer wall of the lifting housing.

[0014] In conjunction with the first embodiment of the first aspect, the present invention provides an eighth embodiment of the first aspect, wherein a material box is fixed on the lifting shell between two adjacent boxes.

[0015] In conjunction with the first aspect, the present invention provides a ninth embodiment of the first aspect, wherein the box body, the lifting shell, and the flip cover are all made of stainless steel, the base has a load-bearing capacity of not less than 70 kilograms, and the rotating connection between the flip cover and the lifting shell is provided with an explosion-proof structure.

[0016] The beneficial effects of this invention are as follows: This invention achieves the effect of automatic lowering of the lifting shell and automatic exposure of the fire extinguisher inside the box when the flip-top is opened by a vertical sliding cooperation structure between the fixed box and the lifting shell, combined with the linkage design of the flip-top and the lifting rod. This simplifies the equipment retrieval operation steps during fire emergency. Operators can quickly retrieve the fire extinguisher without reaching into the box, improving the response efficiency of fire emergency response and meeting the rapid emergency response needs of high-risk places such as airport fuel depots and refined oil depots. This invention uses the linkage between the flip cover and the lifting rod to form a closed loop between the opening and closing action of the flip cover and the lifting action of the lifting housing. There is no hard metal friction impact during the opening and closing process of the flip cover, which can avoid the risk of friction sparks and static electricity accumulation from the structure. At the same time, the rotating connection part of the flip cover can be adapted to a special explosion-proof structure design, which improves the safety of the fire box in high-risk scenarios. This invention utilizes a top support rod and a hinged cover design to automatically support and limit the hinged cover after it is opened, ensuring a stable open state without the need for manual support, thus simplifying emergency operation procedures. Simultaneously, when the lifting housing is in a high, closed position, it completely conceals the fire extinguisher inside the storage box, achieving fully enclosed protection for the fire-fighting equipment. This effectively avoids the aging and failure issues caused by sun and rain exposure in outdoor environments, ensuring that the fire-fighting equipment remains in good working order for a long time.

[0026] This embodiment is a preferred embodiment of the present invention, see below. Figures 1 to 6 The novel fire box provided in this embodiment includes a base 3, at least one box body 2, a lifting shell 1, a flip cover 4, a slide rail 6, a lifting rod 8, a top support rod 7, and a linkage structure set between the flip cover 4 and the lifting rod 8.

[0027] The base 3 serves as the overall support and installation foundation for the fire box. The bottom of the box body 2 is fixed on the base 3. The base 3 is formed by welding metal plates into one piece. In this embodiment, stainless steel plates are preferred to be welded by argon arc welding. The weld is passivated and ground to ensure structural strength and corrosion resistance.

[0028] In one embodiment, the base 3 is a rectangular frame-type load-bearing structure. The base plate of the base 3 is made of stainless steel plate with a thickness of not less than 3mm. The load-bearing design value of the base plate is not less than 70 kg, which can accommodate the load-bearing requirements of two or more heavy-duty dry powder fire extinguishers and carbon dioxide fire extinguishers, and meets the strict safety regulations of oil depots and airport fuel stations.

[0029] The base 3 has four downward-extending mounting legs at its bottom corners. The mounting legs have bolt mounting holes, which can be used to fix the fire box to the hardened cement ground with expansion bolts. At the same time, the bottom surface of the mounting legs is a flat support surface, which can be placed directly and stably on non-hardened ground such as muddy ground and gravel ground without bolt fixing, making it suitable for installation and use in all scenarios of oil depot areas.

[0030] Optionally, the mounting feet of the base 3 are designed to be height-adjustable. The feet use a bolt and screw leveling structure, which can adjust the height of each foot on uneven or sloping ground to ensure that the fire box is level after installation and to prevent the lifting structure from getting stuck due to tilting.

[0031] Optionally, a dedicated grounding terminal is provided on the side of the base 3. The grounding terminal is connected to all metal structural parts of the fire box through a copper jumper wire. When in use, it is connected to the grounding grid of the warehouse area through a grounding wire, which can quickly conduct the static electricity generated in various parts of the equipment to the ground, completely avoiding the risk of static electricity accumulation in flammable and explosive places.

[0032] In another embodiment, the base 3 adopts a split structure, with each box 2 corresponding to a set of independent base units. Multiple sets of base units are detachably connected by connecting rods, and the number and spacing of the boxes 2 can be flexibly adjusted according to the needs of on-site use to accommodate the storage needs of different specifications and quantities of fire extinguishers.

[0033] The box 2 is a hollow cavity structure with an open top. The inner cavity of the box 2 is used to store core fire-fighting equipment such as fire extinguishers and fire wrenches. The bottom of the box 2 is detachably fixed to the base 3 by welding or bolts.

[0034] In one embodiment, the housing 2 adopts a rectangular hollow column structure, integrally bent and welded from stainless steel sheet, resulting in strong structural stability, high space utilization, and easy installation and fixing of auxiliary structures such as the slide rail 6 and lifting rod 8. In this embodiment, two identical rectangular housings 2 are symmetrically fixed on the base 3, arranged symmetrically along the central axis of the base 3 with a spacing of 100mm-300mm. Each housing can hold two 4kg-8kg dry powder fire extinguishers, meeting the conventional fire protection configuration requirements of oil depot locations.

[0035] Optionally, the number of boxes 2 can be adjusted to 1, 3, 4 or more according to usage requirements. Multiple boxes 2 can be arranged in various ways, such as side-by-side symmetrical arrangement or ring array arrangement, all of which are within the protection scope of this invention.

[0036] Optionally, the cross-sectional shape of the housing 2 can be any one of circular, regular hexagonal, elliptical, or oval shapes to suit the storage needs of fire extinguishers of different shapes; when the housing 2 adopts a cylindrical hollow structure, the slide rail 6 adopts an arc-shaped guide rail to fit the cylindrical outer wall, and the lifting housing 1 adopts a corresponding cylindrical hollow structure to ensure smooth lifting and lowering.

[0037] Furthermore, the bottom of the inner cavity of the housing 2 is equipped with a fire extinguisher limiting slot. The shape of the limiting slot is adapted to the bottom of the fire extinguisher bottle, which can radially limit the fire extinguisher and prevent it from tipping over or shifting during the handling of the fire box and the sliding of the lifting shell 1. The inner cavity side wall of the housing 2 is equipped with an equipment partition plate, which can divide the inner cavity into multiple independent spaces to store different equipment such as fire extinguishers, fire hoses, and demolition tools, so as to achieve standardized storage of equipment. The bottom plate of the housing 2 has drainage and ventilation holes with a diameter of 5mm-10mm, which can drain rainwater that seeps into the inner cavity, prevent water accumulation in the inner cavity from causing fire extinguisher corrosion and equipment damage, and at the same time ensure the air pressure balance in the inner cavity to prevent abnormal air pressure caused by temperature changes.

[0038] The lifting housing 1 is a hollow structure that runs vertically through the body. The lifting housing 1 is fitted onto the outside of the box body 2. The inner wall of the lifting housing 1 is provided with a sliding fitting that is compatible with the slide rail 6. The lifting housing 1 slides vertically and vertically along the axial direction of the box body 2 through the cooperation of the sliding fitting with the slide rail 6.

[0039] In the preferred embodiment, the lifting housing 1 is an integral structure, which is simultaneously fitted onto the exterior of two symmetrically arranged boxes 2. This allows the housing parts at the two corresponding positions to slide up and down synchronously, ensuring the synchronicity of the lifting action of the double-box structure. The lifting housing 1 adopts a hollow structure that matches the cross-sectional shape of the box 2. In this embodiment, it is a rectangular tubular structure. The inner cavity cross-sectional dimension of the lifting housing 1 is larger than the outer wall cross-sectional dimension of the box 2. The single-sided fitting gap between the lifting housing 1 and the box 2 is controlled within the range of 0.5mm-2mm. An installation gap for sliding is reserved only in the fitting area corresponding to the slide rail 6. This ensures the smoothness of the lifting action and prevents external dust and rainwater from entering the fitting gap, causing structural jamming and corrosion. It also reduces the risk of friction noise and metal-to-metal sparks during the opening and closing process.

[0040] In another embodiment, the lifting housing 1 adopts a split structure, with each box 2 corresponding to a set of independent lifting housing 1. There is no connecting structure between the sets of lifting housing 1, and the lifting action can be completed independently, which is suitable for the use of a single box opening and closing independently.

[0041] Furthermore, a reinforcing rib is provided on the top of the inner wall of the lifting housing 1. The reinforcing rib is connected to the upper end of the lifting rod 8, which can disperse the supporting force of the lifting rod 8 and prevent the lifting housing 1 from deforming or cracking due to long-term stress. The bottom edge of the lifting housing 1 is provided with an inwardly bent limiting flange, and the top outer wall of the housing 2 is provided with a corresponding limiting block. When the lifting housing 1 slides down to the lowest position, the limiting flange abuts against the limiting block to form a lower limit protection and prevent the lifting housing 1 from falling off the housing 2. When the lifting housing 1 slides up to the highest position, the limiting block abuts against the top of the inner wall of the lifting housing 1 to form an upper limit protection and prevent the lifting housing 1 from sliding beyond its travel range and causing structural damage.

[0042] The outer wall of the housing 2 is provided with a vertically extending slide rail 6. The extension direction of the slide rail 6 is completely consistent with the axial direction of the housing 2. In this embodiment, a set of slide rails 6 is provided on each of the two opposite outer walls of the rectangular housing 2, and two sets of matching sliding mating parts are provided on the inner wall of the lifting housing 1. The symmetrical arrangement of the double slide rails can further improve the stability of the lifting process and avoid the jamming problem caused by unilateral force.

[0043] Optionally, the slide rail 6 can be installed on one side of the outer wall of the housing 2, on the adjacent two sides of the outer wall, or on all four sides of the outer wall. The number of slide rails 6 can be adjusted to 1, 3, 4 or more depending on the specifications of the housing 2 and the lifting load.

[0044] In one embodiment, the slide rail 6 adopts a built-in slide groove type guide rail. The guide rail body has a T-shaped slide groove extending along the axial direction. The sliding mating part adopts a T-shaped slider that is adapted to the T-shaped slide groove. The slider is locked in the slide groove and can only slide along the axial direction of the slide groove. It cannot be disengaged radially, thus ensuring the limiting accuracy of the lifting and lowering mating.

[0045] Optionally, the slide rail 6 can be any one of dovetail groove guide rail, linear ball guide rail, or external cylindrical guide rail; the sliding mating parts can be any one of nylon guide blocks, guide rollers, or deep groove ball bearings. Among them, the nylon guide blocks can avoid direct metal-to-metal friction, fundamentally eliminate friction sparks, further improve explosion-proof safety, and have self-lubricating properties, eliminating the need for additional lubrication, making them suitable for long-term outdoor use.

[0046] Furthermore, buffer pads are provided at both ends of the slide rail 6, which can buffer the upper and lower limit positions of the lifting housing 1, avoid sparks and abnormal noises caused by rigid metal impact, reduce structural wear, and extend the service life of the equipment.

[0047] The lifting rod 8 is located inside the housing 2. Both ends of the lifting rod 8 are connected to the housing 2 and the lifting housing 1, respectively. The lifting rod 8 always applies an upward supporting force to the lifting housing 1 and also has a stroke locking function, which can lock at a specified stroke position to keep the position of the lifting housing 1 fixed.

[0048] In a preferred embodiment, the lifting rod 8 is a hydraulic support rod with a trigger-locking function. The lower end of the hydraulic support rod is hinged to the inner bottom of the housing 2 through a hinge seat, and the upper end of the hydraulic support rod is hinged to the top of the inner wall of the lifting housing 1 through a hinge seat. The hinge connection method can adapt to the slight angle change of the hydraulic support rod during the lifting process and avoid structural interference and jamming.

[0049] Specifically, the hydraulic support rod is set at the inner corner of the rectangular box 2 near the hinge side of the flip cover 4. The hydraulic support rod is arranged vertically along the height of the box 2. The corner installation method can fix the mounting seat of the hydraulic support rod on two adjacent inner walls of the box 2 at the same time, which greatly improves the stability of the installation structure. At the same time, it does not occupy the core storage space inside the box 2, and avoids interference with the installation and operation of fire extinguishers and other equipment.

[0050] Optionally, the installation position of the lifting rod 8 can be adjusted to the middle of the inner wall of the box 2, the center of the inner cavity of the box 2, or symmetrically arranged on opposite sides of the inner wall of the box 2. The number of lifting rods 8 can be adjusted to 1, 2, or 4 sets according to the specifications and lifting load of the box 2. When multiple sets of lifting rods 8 are symmetrically arranged, the stability of the lifting support can be further improved, adapting to the needs of large-size and heavy-load fire boxes.

[0051] In another embodiment, the lifting rod 8 uses a nitrogen gas spring with a locking function. The gas spring has a constant supporting force, making the lifting action smoother, and also has excellent low-temperature resistance, making it suitable for outdoor use in cold northern regions. In yet another embodiment, the lifting rod 8 uses an electric push rod, which, together with a limit switch and a control module, can realize the electric lifting control of the lifting housing 1, adapting to the remote control needs of intelligent warehouses. In yet another embodiment, the lifting rod 8 uses a structure of compression spring combined with a mechanical locking mechanism. The compression spring always applies an upward supporting force to the lifting housing 1, and the mechanical locking mechanism works with the linkage structure to realize the trigger control of locking and unlocking.

[0052] Furthermore, the surface of the lifting rod 8 is treated with anti-corrosion passivation, and the hinge part uses a stainless steel pin, which is suitable for outdoor use in humid and corrosive environments, ensuring the reliability of operation during long-term use; the supporting force of the lifting rod 8 can be matched according to the weight of the lifting housing 1, ensuring that in the unlocked state, the weight of the lifting housing 1 can overcome the supporting force and slide smoothly downwards, and in the locked state, the supporting force can stably support the lifting housing 1 to keep it in a high position, and there will be no problem of it falling down on its own.

[0053] The flip cover 4 is rotatably connected to the top of the lifting housing 1 and is used to open and close the top opening of the lifting housing 1; the lower end of the top support rod 7 is fixed to the housing 2, and the upper end of the top support rod 7 abuts against the inner end face of the flip cover 4; a linkage structure is provided between the flip cover 4 and the lifting rod 8, and the opening and closing action of the flip cover 4 triggers the locking and unlocking of the lifting rod 8 to realize the automatic lifting of the lifting housing 1.

[0054] In the preferred embodiment, the flip cover 4 is an integral structure. The integral flip cover 4 is also hinged to the top edge of the integral lifting housing 1 through an explosion-proof hinge, which can open and close the top openings of the two housings 2 simultaneously, adapting to the usage requirements of simultaneous operation of the two housings.

[0055] The explosion-proof hinge is made of stainless steel, and the hinge pin sleeve is equipped with a copper bushing to prevent sparks from being generated by metal friction during opening and closing. At the same time, an anti-static bridging copper sheet is set at the hinge to ensure the equipotential connection between the flip cover 4 and the lifting housing 1, eliminate the risk of static electricity accumulation, and meet the explosion-proof safety requirements of flammable and explosive places.

[0056] Optionally, the flip cover 4 adopts a split structure, with each lifting housing 1 corresponding to an independent flip cover 4, which can independently complete the opening and closing action, adapting to the needs of single-box independent use; the hinge part of the flip cover 4 can be equipped with a damping hinge to make the opening and closing action of the flip cover 4 smoother and avoid the impact and abnormal noise caused by rapid opening and closing.

[0057] The linkage structure is set at the hinge end of the flip cover 4, corresponding to the trigger end of the locking valve of the lifting rod 8. In this embodiment, the linkage structure adopts a trigger-type pressing mechanism. The hinge end of the flip cover 4 is provided with a cam block, and the trigger end of the locking valve of the lifting rod 8 is provided with a pin. When the flip cover 4 rotates around the hinge axis to the open state, the cam block rotates synchronously with the flip cover 4, pressing the pin to trigger the locking valve of the lifting rod 8, so that the locking state of the lifting rod 8 is released. The upward supporting force of the lifting rod 8 is less than the weight of the lifting housing 1. The lifting housing 1 slides downward along the slide rail 6. The top of the fire extinguisher placed in the inner cavity of the box 2 is exposed outside the top opening of the lifting housing 1. The operator can directly take the fire extinguisher without reaching into the box. When the flip cover 4 rotates to the closed state, the cam block rotates in the opposite direction with the flip cover 4, releasing the pressing on the pin. The locking valve of the lifting rod 8 is reset, and the lifting rod 8 returns to the locked state, which can stably support the lifting housing 1 to remain in a high fixed state. The flip cover 4 completely closes the top opening of the box 2.

[0058] In another embodiment, the linkage structure adopts a linkage mechanism with two ends of the linkage being hinged to the hinge end of the flip cover 4 and the locking trigger end of the lifting rod 8, respectively. When the flip cover 4 is opened and closed, the linkage drives the locking mechanism to complete the unlocking and resetting. In yet another embodiment, the linkage structure adopts a pull-wire trigger mechanism. One end of the pull wire is fixed to the inner end face of the flip cover 4, and the other end is connected to the locking trigger end of the lifting rod 8. When the flip cover 4 is opened, pulling the pull wire triggers the unlocking. The structure is simple and easy to install and debug.

[0059] Furthermore, the latching edge of the flip cover 4 is provided with a rubber sealing strip. When the flip cover 4 is closed, the sealing strip can fill the gap between the flip cover 4 and the lifting housing 1 to achieve a waterproof and dustproof seal, preventing rainwater and dust from entering the interior of the housing 2 and causing equipment aging and damage. The free end of the flip cover 4 can be provided with an explosion-proof latch lock, which can lock the flip cover 4 and the lifting housing 1 when closed, providing an anti-theft function and preventing unauthorized personnel from opening it at will.

[0060] The lower end of the top support rod 7 is welded and fixed to the top edge of the box body 2 through a fixing seat. The upper end of the top support rod 7 is provided with an abutment part. During the entire process of opening and closing the flip cover 4, the abutment part always maintains smooth sliding contact with the inner end face of the flip cover 4.

[0061] In this embodiment, each box 2 is provided with a set of top support rods 7, and the two sets of top support rods 7 are arranged symmetrically to ensure uniform support force on the flip cover 4.

[0062] In one embodiment, the top support rod 7 is a stainless steel round rod of fixed length, and the abutment part is a nylon slider with an arc surface. The nylon slider can avoid sparks generated by metal friction with the inner end face of the flip cover 4, and at the same time has self-lubricating properties, making the sliding smoother. When the flip cover 4 is fully opened, the top support rod 7 forms a stable support limit for the flip cover 4, so that the flip cover 4 maintains a fixed opening angle of 90°-120° without manual support, and avoids the flip cover falling back and blocking the equipment access path when used in an emergency.

[0063] Optionally, the top support rod 7 adopts an adjustable length screw structure, which can be adjusted to adapt to different opening angle requirements of the flip cover 4; the top support rod 7 can adopt a hydraulic buffer rod to provide buffering force during the opening of the flip cover 4, avoid the impact generated by the rapid opening of the flip cover 4, and improve the stability of the support; the abutment part can adopt a guide roller and universal ball joint structure to further reduce sliding friction resistance and improve the smoothness of the opening and closing action.

[0064] A handle 5 is fixed to the outer wall of the lifting housing 1. In this embodiment, the handle 5 is located in the middle of the front outer wall of the lifting housing 1, and is made of stainless steel bent into one piece. The surface is covered with a non-slip rubber sleeve, which makes it easy for operators to lift the lifting housing 1 to complete the closing and resetting operation, thus improving the convenience of use. Optionally, the handle 5 can be set as a folding structure or a double-sided symmetrical arrangement structure, which can be flexibly adjusted according to the usage scenario.

[0065] Material box 9 is fixed on the lifting shell 1 between two adjacent boxes 2. Material box 9 is a hollow cavity structure with a flip cover. It can be used to store auxiliary emergency equipment such as fire inspection logs, inspection records, gas masks, heat insulation blankets, and fire wrenches, so as to realize the centralized and standardized storage of fire emergency materials and facilitate daily inspection management and unified emergency allocation and use.

[0066] Optionally, the material box 9 can adopt a drawer-type structure or an open storage compartment structure. The inner cavity of the material box 9 can be equipped with a divider to divide the inner cavity into multiple independent storage spaces to adapt to the classification and storage needs of different equipment. The door panel of the material box 9 can be equipped with a transparent observation window, so that the storage status of the internal materials can be viewed without opening the door, thereby improving the efficiency of daily inspection.

[0067] Furthermore, a transparent explosion-proof observation window can be installed on the front outer wall of the lifting housing 1. The observation window is made of polycarbonate sheet, which allows for direct viewing of the pressure value and condition of the fire extinguisher inside the housing 2 without opening the flip cover 4, greatly improving the efficiency of daily inspections and avoiding missed inspections. Warning signs, fire extinguisher specifications, and operating instructions can be etched or pasted on the outer wall of the lifting housing 1, making it easy for operators to quickly master the usage method and meeting the safety signage management requirements of the storage area.

[0068] In this embodiment, all metal structural components, including the housing 2, lifting shell 1, flip cover 4, base 3, slide rail 6, and top support rod 7, are made of stainless steel. 304 stainless steel, 316L stainless steel, and 201 stainless steel can be selected depending on the application scenario. 316L stainless steel possesses excellent resistance to chloride ion corrosion, making it suitable for long-term use in coastal areas and high-humidity environments. The overall structure features a fully conductive interconnect design. Through the grounding terminal of the base 3, it is connected to the warehouse grounding grid at the same potential, allowing static electricity generated in various parts of the equipment to be quickly conducted to the ground, completely avoiding the risk of combustion and explosion caused by static electricity accumulation.

[0069] All metal mating surfaces are passivated and polished, eliminating the impact and friction sparks from hard metals during opening, closing, and lifting. The hinge of the flip cover 4 uses explosion-proof hinges and copper bushings, while the sliding mating parts are made of nylon. Structurally, this completely avoids the generation of friction sparks. Even in daily use scenarios with low-frequency opening and closing, it can fundamentally eliminate any possible points of combustion and explosion risk, fully meeting the explosion-proof safety specifications for flammable and explosive locations such as airport fuel depots and refined oil storage depots.

[0070] Based on the core concept of this invention, various modified embodiments can be derived, all of which fall within the protection scope of this invention: In one modified embodiment, the fire extinguisher box adopts a single-box structure, with one box 2 fixed on the base 3, and correspondingly set with a set of lifting shells 1, a set of flip covers 4, a set of lifting rods 8 and a set of top support rods 7. The overall structure is smaller in size, adaptable to installation scenarios with limited space, and can be used for storing fire extinguishers in indoor power distribution rooms, computer rooms, office areas and other places.

[0071] In another modified embodiment, the fire extinguisher box adopts a three-box side-by-side structure. Three boxes 2 are fixed on the base 3 with equal spacing. The lifting shell 1 is an integrated structure and is fitted on the outside of the three boxes 2. The flip cover 4 is an integrated structure and completes the opening and closing control simultaneously. It can store 6 or more fire extinguishers at the same time and is suitable for use scenarios with large protection areas such as large oil depots and airport aprons.

[0072] In another modified embodiment, the lifting action of the lifting housing 1 adopts a gravity-type falling structure. The lifting rod 8 only provides upward buffering force. When the flip cover 4 is closed, the lifting housing 1 is locked in a high position by a locking structure. When the flip cover 4 is opened, the locking is unlocked simultaneously. The lifting housing 1 slides down along the slide rail 6 under its own weight. The structure is simpler, the failure rate is lower, and it is suitable for application scenarios with high cost control requirements.

[0073] The specific operating procedure is as follows: The operator flips the cover 4 outwards, and the cover 4 rotates around the hinge axis to open. The linkage structure at the hinge end simultaneously triggers the lifting rod 8 to release the locked state. The upward supporting force of the lifting rod 8 is less than the weight of the lifting housing 1. The lifting housing 1 slides smoothly downwards along the slide rail 6, and the top of the fire extinguisher stored in the box 2 is gradually exposed through the top opening of the lifting housing 1. During this process, the abutting part at the upper end of the top support rod 7 always maintains sliding contact with the inner end face of the cover 4. When the cover 4 rotates to the maximum opening angle, the top support rod 7 provides stable support for the cover 4, keeping it in a fixed open state without manual assistance. At this time, the operating parts of the fire extinguisher are fully exposed, and the operator can directly and quickly take the fire extinguisher without reaching into the box to complete the emergency response to the initial fire.

[0074] After the emergency response is completed, the operator lifts the lifting housing 1 upwards using handle 5. The lifting housing 1 slides upwards along the slide rail 6 to the highest position, and the lifting rod 8 extends to its maximum stroke simultaneously. At this time, the operator rotates the flip cover 4 inwards, so that it locks into the top opening of the lifting housing 1. The linkage structure at the hinge end of the flip cover 4 simultaneously triggers the lifting rod 8 to return to the locked state. The lifting rod 8 can stably support the lifting housing 1 and keep it in a fixed high position, preventing it from falling down on its own. The flip cover 4 completely closes the top opening of the box 2, achieving full-enclosed protection for the fire extinguisher and completing the reset and storage of the fire extinguisher box.

[0075] This invention is not limited to the optional embodiments described above, and anyone can derive other various forms of products based on the inspiration of this invention. The specific embodiments described above should not be construed as limiting the scope of protection of this invention; the scope of protection of this invention should be determined by the claims, and the specification can be used to interpret the claims.
