Description

Technical Field

[0001] This invention relates to a multi-socket safe storage device, and more specifically, to a multi-socket safe storage device with a custom structure that can safely store multiple sockets and can be customized for application according to the installation environment. Background Technology

[0002] A multi-outlet socket is a power supply device that can simultaneously connect multiple electronic devices and is used in almost all environments, including homes, offices, and industrial sites. Especially in spaces where the location or number of wall sockets is limited, multi-outlet sockets function as an essential device, offering the advantage of enabling multiple devices to operate effectively. However, in such environments, multi-outlet sockets are constantly exposed, making them susceptible to direct environmental influences.

[0003] In real-life spaces, multi-outlet sockets are located in various places such as on the floor, walls, under tables, and behind electronic devices. Therefore, dust, hair, and foreign objects can easily enter the socket holes. These contaminants accumulate near the plug terminals, causing poor electrical contact and potentially leading to overheating or sparks. In particular, the accumulation of flammable dust can be a direct cause of fire, and the danger is even greater for multi-outlet sockets located in hard-to-clean or out-of-sight areas.

[0004] Multi-outlet sockets used in humid environments can also cause serious problems. In spaces with moisture, such as bathrooms, kitchens, and laundry rooms, water vapor or droplets can seep into the sockets, potentially causing electrical leakage or electric shock. Considering that a significant portion of indoor electrical fires are caused by short circuits due to moisture infiltration, the necessity of structural protection for multi-outlet sockets is particularly important.

[0005] In some existing technologies, a box-type protective case that can accommodate multiple sockets is provided to solve this problem. This structure aims to prevent dust or moisture from entering by physically enclosing the multiple sockets, and it is expected to be effective to some extent. However, when using the protective case, the cover must be opened every time electrical equipment and the multiple sockets are connected, which is inconvenient. Especially in environments where multiple sockets are used frequently or where peripheral devices are frequently switched, this structure can actually be inconvenient.

[0006] Box-type protective cases are not space-efficient due to their large size and volume. When installed in confined spaces or needing to be mounted against a wall, the case itself can become an obstacle and may interfere with other furniture or equipment. Furthermore, manufacturing with a uniform size limits compatibility with various multi-outlet socket models. It is difficult to apply a standardized approach to multi-outlet sockets that require different sizes or lengths depending on the user's environment or product specifications.

[0007] Existing storage structures have limitations in controlling the risk of internal temperature rise. If the internal components of a multi-outlet socket continue to generate heat during use, causing the temperature within the storage space to gradually increase, the accumulated heat in the enclosed space will further exacerbate the fire risk. Therefore, existing storage-type protection devices do not have adequate built-in fire prevention measures and only provide simple shielding.

[0008] The stability of multi-socket protection devices is also an issue that needs to be considered. Existing protective shells or covers lack structures for external fixation, or are designed with only limited structures. As a result, it is common to see situations where tape, ropes, nails, etc., are used for haphazard attachment on site. This not only reduces the stability of the installation and affects aesthetics, but also compromises safety.

[0009] Cables connected via multi-socket outlets are also in a protection blind spot. Traditional devices perform protection functions centered on the multi-socket outlet itself, but no friction-fixing or sealing structure is installed in the area where the cable passes. Therefore, as the cable moves, dust or moisture may seep into the interior, and because the cable is not secured, the entire device may shake or fall off.

[0010] Some technologies attempt to use thermally reactive materials or magnetic switching technology, but devices integrating these technologies into a unified structure are rare. If the magnetic switching structure is used as a single component, or if the function of cutting off the circuit after heat sensing relies on external devices, it is difficult to achieve a substantial fire extinguishing function. Therefore, an integrated structure is needed that can operate independently and transform the interior into an asphyxiating space when the internal temperature rises.

[0011] In view of the actual situation of the prior art, there is a clear technical need for a safety storage device with the following structure: it can be flexibly applied to various installation environments, completely protects multi-socket outlets from external hazards, can be easily opened or closed when connected to cables, and can automatically respond in the event of a fire. There is an urgent need to propose a technical solution to address these problems, and this invention aims to provide such a solution.

[0022] In one embodiment of the present invention, the cable fixing protrusion can be configured to melt when heated to a temperature exceeding a preset critical temperature, and seal the inner space of the sealing portions at both ends and the outer peripheral surface of the cable connected to the multi-position socket, thereby preventing gas generated in the inner space of the cover body from leaking to the outside, and forming the inner space of the cover body into a suffocating space.

[0023] Furthermore, the magnetic opening and closing part can be configured such that when heated to a temperature exceeding a preset critical temperature, the part that originally fixed the magnetic component in the form of wrapping the magnetic component melts and seals the opening cutting line forming part, thereby blocking the gas generated in the inner space of the cover body from leaking to the outside, and forming the inner space of the cover body into a suffocating space.

[0050] Referring to the accompanying drawings, the multi-socket safety storage device 100 of this embodiment, through its housing body 110 with a specific structure, end sealing portions 120, and internal opening and closing portion 130, can be appropriately optimized and used for various installation environments. Therefore, it can solve the problem in the prior art that leakage accidents, electric shock accidents, or fire accidents may occur due to dust, foreign objects, or moisture seeping into the socket holes of the multi-socket; it can solve the cumbersome problem of having to open and close the protective shell of the box-type structure used for sealing and storing multi-sockets to connect to electronic products; and it can solve the problem of the protective shell occupying a lot of space.

[0051] The following will refer to Figures 1 to 5 The components constituting the multi-socket safety storage device 100 of this embodiment will be described in detail.

[0052] Specific composition and structure of the cover body 110

[0053] The cover body 110 is formed as a hollow cylindrical structure that completely encloses the exterior of the multi-socket socket, providing protection by completely isolating the socket body from external dust, foreign objects, moisture, etc. The cover body 110 is manufactured using a one-piece molding process, eliminating the need for additional joining steps. It also possesses high resistance to external impacts and maintains structural consistency. This cylindrical structure is flexibly adaptable to multi-socket sockets of various shapes, and its design incorporates open ends and a certain degree of elasticity, allowing for easy insertion of the multi-socket socket into the internal space.

[0054] The cover body 110 is made of a flame-retardant material with a predetermined elastic resilience and is designed to maintain its original shape even under temperature changes or repeated physical deformation in the usage environment. Typically, silicone or flame-retardant rubber composite materials with a flame retardancy rating of V-0 or higher are used, ensuring both flexibility and resilience, and providing structural stability even under long-term use. When a multi-socket socket is inserted, the elastic structure facilitates the generation of friction between the inside and outside, helping to improve the fixing force.

[0055] The cover body 110 can be provided in various lengths and diameters, or in a variety of sizes and with cuttable lines, to accommodate various multi-socket sizes. It can also be designed with cuttable lines to allow users to adjust the size, or to increase the length by inserting extensions. This structure is a key element in enabling customized storage solutions.

[0056] Both ends of the cover body 110 are integrally formed with end sealing portions 120, and internal opening and closing portions 130 for opening and closing the interior are also integrated with both ends of the cover body 110. Thus, while performing its function of protecting the storage box independently, the cover body 110, through its combination with other components, forms a comprehensive and secure storage structure. The multi-socket inserts inside are secured by the structural clamping force of the cover body 110, preventing them from easily detaching even under external impact.

[0057] Functional coatings can be layered on the exterior and interior of the cover body 110, or they can be formed by inserting them simultaneously during molding. The exterior uses an external coating 111 for enhanced anti-slip and waterproof functions, while the interior uses an internal coating 112 for heat suppression and fireproofing. In addition, a fire extinguishing layer 113 for releasing fire extinguishing agents when the temperature reaches a specified level is also disposed in the internal structure of the cover body 110, thereby achieving multiple safety functions.

[0058] External coating 111

[0059] The outer coating 111 is a structure that is coated or laminated on the entire outer surface or selected area of ​​the cover body 110. Its main function is to block the penetration of the external environment and ensure external friction, thereby preventing slippage. The outer coating 111 helps prevent external pollutants such as moisture, dust, and foreign objects from being transmitted to the interior of the cover body 110, thus helping to improve stability in the living environment.

[0060] The outer coating 111 is formed of silicone-based waterproof coatings, fluoropolymers, or nano-waterproof coatings, and has hydrophobic surface properties. Even if water droplets come into contact with the exterior, they will not penetrate the interior but will instead guide the water droplets to roll off the surface. This coating not only inhibits ordinary moisture but also inhibits the adhesion of everyday contaminants (beverages, dust, etc.), which is very helpful in maintaining the cleanliness of the device.

[0061] A predetermined uneven structure is formed on the surface of the outer coating 111 of the main body to prevent slippage when the device is held by hand. This uneven structure can be engraved or embossed into a specific pattern to increase friction and ensure safety when the user handles or secures the device. Furthermore, this structure provides visual identification and enhances the aesthetic appeal of the product.

[0062] The outer coating 111 can be applied using various methods such as spraying, lamination, and extrusion. For example, the coating can be formed on the outer surface by silicone spraying, or a rubber outer skin can be directly laminated by extrusion to create an integrated structure. Depending on the manufacturing method, the thickness or hardness of the outer coating 111 can be adjusted, and it can be deformed in various ways according to the usage environment.

[0063] The external coating 111 needs to ensure durability so that it can withstand external wear and scratches over a long period after installation. This can be achieved by providing heat resistance, abrasion resistance, and UV resistance. Even during long-term use in harsh industrial environments or outdoor settings, its functionality should not be degraded; therefore, the selection of coating materials and processing methods are crucial. Thus, the external coating 111 can significantly improve the overall protective reliability of the cover body 110.

[0064] Internal coating 112

[0065] An internal coating 112 is applied or laminated to the inner surface of the housing body 110. This coating serves as a functional protective layer with fire-retardant and heat-resistant properties to address the heat generated during the use of the multi-socket socket. The internal coating 112 is positioned in direct contact with the outer peripheral surface of the multi-socket socket to prevent heat from the socket itself (generated by electrical load) from spreading throughout the housing body 110. This improves the overall durability of the device and reduces the risk of fire.

[0066] The internal coating 112 can be composed of a high-heat-resistant silica-based coating agent, ceramic nanocomposite materials, or flame-retardant thermosetting resins. This material will not deform or burn at high temperatures and has a low coefficient of thermal expansion, maintaining its original shape even after long-term use. Furthermore, this type of heat-resistant material maintains strong adhesion under external impact, preventing coating peeling or lifting during use.

[0067] The surface of the coating 112 inside the main body has a certain degree of unevenness, which improves the tightness of the fit with the multi-socket body and guides the air circulation through the micro-gap, thereby assisting natural cooling. This unevenness creates frictional resistance when in contact with the outer periphery of the multi-socket, preventing the multi-socket from shaking or moving inside the device. Therefore, stable fixation can be achieved even in places susceptible to vibration or movement.

[0068] The internal coating 112 can be applied to the inner surface of the cover body 110 during the manufacturing process by spraying, in-mold lamination, or extrusion coating. For example, a ceramic flame-retardant film can be formed by in-mold embedding, or a thin and uniform coating can be sprayed. This method has the advantages of reducing production costs while consistently ensuring durability and flame-retardant performance.

[0069] The internal coating 112 of the main body has inert properties, meaning it does not undergo a chemical reaction when the temperature rises, and provides functions such as mitigating heat buildup inside the cover body 110 and suppressing flame spread. In particular, it can fundamentally prevent problems caused by heat buildup in environments where multi-socket outlets are used for extended periods, and can delay damage to the entire structure even in the event of an electrical overload, thereby ensuring sufficient time for external evacuation. Therefore, the internal coating 112 can be considered the core structure for ensuring the heat resistance safety of the multi-socket outlet storage device.

[0070] Fire Extinguishing Floor 113

[0071] Fire extinguishing layers 113 are attached in multiple layers at predetermined intervals on the inner surface of the coating 112 inside the main body. If a high temperature exceeding a specific critical temperature occurs inside the main body 110, fire extinguishing agents are automatically released to extinguish the fire in its initial stage. This structure automatically responds to the initial fire, prevents secondary damage caused by electrical accidents, and is designed to autonomously suppress the spread of fire even without human intervention.

[0072] Fire suppression layer 113 can typically consist of extinguishing agents in the form of heat-reactive capsules or microcapsules, or a compressed, built-in fire suppression system that bursts upon heating to release extinguishing powder. For example, when heated, it operates by rupturing the outer casing, releasing built-in potassium carbonate or sodium bicarbonate powder into the surrounding area, thus blocking electrical sparks and suppressing oxygen supply. This structure is designed to perform fire suppression functions efficiently, even in confined spaces.

[0073] The extinguishing layers 113 are spaced apart on the inner surface coating and are not directly exposed inside the enclosure body 110. They activate only when the temperature rises above a specified standard (e.g., 150°C to 180°C). This prevents accidental activation due to daily temperature increases and ensures activation only at temperatures where a fire is actually possible, thus reducing unnecessary agent consumption. Therefore, the built-in agents have a long shelf life and can be used for an extended period even without regular replacement.

[0074] Multiple fire suppression layers 113 are arranged at predetermined intervals to ensure uniform coverage of the entire area, even in cases of uneven internal temperature distribution. Each fire suppression layer is preferentially positioned around high-heat areas of multi-socket outlets (e.g., cable connections) to prevent the spread of flame throughout the installation. Furthermore, the structure can be designed such that, upon activation of a fire suppression layer, the internal space transforms into a sealed, asphyxiating space, thereby suppressing further combustion.

[0075] Fire suppression layer 113 is not merely a physical device, but functions as an active fire prevention system that significantly enhances the internal safety of the enclosure 110. Thus, in the event of an electrical fire, users can safely and manually extinguish it without additional intervention, minimizing the possibility of fire spread. Furthermore, because this structure can automatically block hazards before fire response, it forms the basis for stable operation even in high-risk environments where multiple outlets are required.

[0076] The extinguishing agent release principle of fire extinguishing layer 113

[0077] The fire extinguishing layer 113 is installed in the inner space of the main body 110. In the early stage of a fire that may occur in the multi-socket outlet, the fire extinguishing layer 113 automatically activates and releases fire extinguishing agents, thereby suppressing the spread of flames. This structure is attached to the inner circumferential surface of the inner coating 112 of the main body at predetermined intervals and has a thermally reactive structure that activates when the internal temperature exceeds a preset critical temperature.

[0078] Fire extinguishing agents are typically composed of non-conductive, fixed powders (e.g., sodium bicarbonate, potassium carbonate, potassium bicarbonate (KHCO3), ABC powder, etc.). The fire extinguishing layer 113 containing the fire extinguishing agent has a capsule-type or pocket-type storage structure. When the internal temperature reaches approximately 150°C, the outer skin of the sealed capsule or pocket softens or ruptures due to the heat, at which point the internal fire extinguishing powder disperses into the space surrounding the multi-socket socket.

[0079] The released extinguishing agent is made of an insulating material suitable for electrical fires, and it comes into direct contact with the plug terminals, wire connections, and internal connectors of multi-socket sockets, thereby extinguishing the flames and absorbing heat. Simultaneously, the agent blocks the oxygen supply, inhibiting or terminating the combustion reaction. Especially since the space inside the device is sealed, the agent has a longer residence time, and the extinguishing effect is rapidly apparent.

[0080] Furthermore, the extinguishing layer 113, while releasing the extinguishing agent, also serves to transform the internal space into an asphyxiating space. This is achieved through the automatic closure of the external channels via the cable fixing protrusion 121 and the magnetic opening and closing part 132. The released agent eliminates residual combustion conditions by absorbing or replacing internal oxygen. This dual-blocking mechanism provides higher safety and better performance than a simple jet-type fire extinguishing device.

[0081] Finally, the activation of fire suppression layer 113 is achieved through a passive triggering method based on thermal reaction, requiring no power supply or external sensors. Therefore, it can reliably perform fire suppression even in the event of a power outage or in an unmanned environment. This differs from existing fire detection methods based on electrical sensors, representing a design that is simple in structure and provides high reliability.

[0082] Specific embodiments of fire extinguishing layer 113

[0083] Annular structure embodiment of fire extinguishing layer 113

[0084] In the annular structure embodiment of the extinguishing layer 113, the extinguishing layer 113 is installed in an annular shape with a specified width along the cylindrical inner circumferential surface of the cover body 110, forming an integral, surrounding extinguishing agent storage structure. This ring can be a single-capsule structure or a strip structure formed by connecting continuous capsules. When heated to a specified temperature or above, the outer skin of the ring opens through a thermal reaction, dispersing the extinguishing agent inside.

[0085] This ring-shaped structure offers advantages such as ease of installation, efficient use of internal space, and the ability to achieve uniform 360-degree fire suppression spray centered on the entire multi-socket unit. In particular, the ring's cross-section can be designed in various shapes, including semi-circular, triangular, or quadrilateral, with the choice made based on the spray direction and distribution range. The outer sheath is made of low-melting-point thermoplastic film or polymer resin, among other materials.

[0086] A thermal reaction capsule is inserted at predetermined intervals inside the annular structure, and it is designed so that multiple spray spaces can be activated simultaneously or sequentially through uniformly distributed heat. In some embodiments, the annular structure may contain nano-encapsulated extinguishing agents (e.g., micropowder), which, upon rupture, can achieve fine dispersion, which helps to evenly diffuse the extinguishing agent throughout the space.

[0087] The annular structure is secured to the interior of the cover body 110 using clips, adhesive silicone, or slots. This securing element is designed to maintain its position even under vibration or impact, and to retain a certain degree of its shape after spraying, ensuring the continued release of residual extinguishing agent. Furthermore, openings or slits can be designed for replenishing or replacing the agent inside the ring.

[0088] This ring-shaped fire extinguishing layer 113 has the advantages of being repeatedly installable and mass-produced through molding or injection molding during the manufacturing process. Therefore, it is suitable for continuously produced products such as multi-socket storage devices. Moreover, the width, thickness, and placement of the ring can be adjusted according to the size or shape of the device, thus enabling customized applications for various product series and achieving excellent fire response capabilities without increasing the complexity of the equipment.

[0089] Example of the mesh structure of fire extinguishing layer 113

[0090] The mesh structure embodiment of the fire extinguishing layer 113 is a structure configured in the form of a mesh or fiber network along the inner circumferential surface of the inner coating 112 of the body, with small fire extinguishing agent capsules inserted at each intersection or branch point of the mesh. This structure can quickly detect heat diffusion over a large area and guide the fire extinguishing agent to be sprayed simultaneously at multiple locations.

[0091] Thermally reactive films or microcapsules are arranged at predetermined intervals on a flexible fiber material with a mesh structure (e.g., flame-retardant polyester or glass fiber). When the external temperature exceeds a set critical value, the capsules at the corresponding locations rupture or the film melts, thereby releasing the agent. The advantage of this structure is that it can be flexibly applied even to multi-position sockets with complex internal shapes.

[0092] The mesh structure effectively disperses the agent throughout the space, enabling rapid response even if multiple internal heat sources are present. In particular, it directly contacts fire-prone points such as plug terminals and cable connections in multi-socket outlets, allowing for selective protection. Its lightweight and space-saving design does not hinder internal cooling.

[0093] The mesh structure features a detachable design for easy maintenance and can be easily installed on the internal coating 112 of the main body using adhesive fasteners, Velcro connectors, or insert slot fasteners. Furthermore, this structure is easily visible from the outside, facilitating visual inspection and determination of replacement cycles. If designed as a semi-transparent structure, users can also visually confirm the remaining amount of medication.

[0094] The mesh-structured fire extinguishing layer 113 is particularly effective in structures requiring large-area protection, such as large-area multi-socket sockets or industrial multi-socket storage devices, enabling a distributed safety system to address multiple heat points. This structure can be flexibly applied to customized multi-socket storage devices as described in this invention, and can be extended to various fields requiring on-site customized fire response.

[0095] Specific composition and structure of the sealing parts 120 at both ends

[0096] The two end sealing portions 120 are integrally formed at both ends of the cover body portion 110, providing a sealing structure that isolates the internal space of the cover body portion 110 from the external environment. The two end sealing portions 120 are formed into a hollow cylindrical shape with an outer diameter of 10% to 50% of the outer diameter of the cover body portion 110, and adopt a structure that wraps around the two ends of the multi-socket socket housed inside. This prevents dust, moisture, foreign objects, etc. from entering the interior of the multi-socket socket and improves the airtightness of the entire device.

[0097] The end seals 120 are made of a flame-retardant material with a predetermined elastic recovery force, which will not deform during use and can prevent damage caused by external impacts. Rubber-based synthetic resins or silicone-based flame-retardant polymers can be used, which provide enhanced adhesion between the multi-socket socket and the end seals 120 and disperse externally applied mechanical loads. Furthermore, structural consistency is maintained even under repeated use and disassembly.

[0098] The end seals 120 are designed to allow cables connecting the internally housed multi-socket outlet to external electrical equipment to pass through. The end seals 120 form internal channels to facilitate smooth cable routing and easy power connection between the multi-socket outlet and electronic devices. This structure provides an environment where the multi-socket outlet can still be used continuously even when sealed.

[0099] Additional structures such as a cutting line forming part 122 and a hanging ring 123 may be integrally formed on the outer surface of the sealing parts 120 at both ends. The cutting line forming part 122 is designed to be adjustable by cutting the length of the sealing parts 120 at both ends according to the user's needs, thereby achieving flexible setting without being limited by fixed size. The hanging ring 123 provides the function of fixing the entire device or hanging it on the wall, ceiling, furniture, etc. by connecting to an external fixing point.

[0100] After the end-sealing portions 120 are combined with the cover body 110, they work in conjunction with the internal opening and closing portions 130 to maintain the open or sealed state of the entire device. Internal components such as cable-fixing protrusions 121 are formed on the inner surface of the end-sealing portions 120, thereby securely securing the internal cables and preventing external intrusion. Therefore, the end-sealing portions 120 are not merely finishing components, but function as core elements that assist in the airtightness, stability, and connectivity of the entire device.

[0101] Cable fixing protrusion 121

[0102] Multiple cable-fixing protrusions 121 are formed on the inner surface of the end-sealing portions 120. These protrusions are protruding structures that contact the outer surface of the cable and provide fixing force as the cable passes through the end-sealing portions 120. This structure is formed to protrude a predetermined height from the inner surface and restricts cable movement, preventing it from detaching due to vibration or impact. This allows for a stable power supply to electrical equipment connected to multi-socket sockets.

[0103] The cable fixing protrusion 121 is molded from a rubber-like elastomer or an elastic composite resin material, thereby flexibly deforming on the contact surface with the cable and generating appropriate friction. To flexibly adapt to different cable outer diameters, multiple protrusions are arranged at predetermined intervals, and each protrusion can be shaped to wrap around the outer surface of the cable in a viscoelastic compression manner. This allows for the matching of cables of various specifications.

[0104] In addition to physically securing the cable, the cable-fixing protrusions 121 act as the first line of defense against external dust or moisture seeping into the interior space. When the cable passes between the protrusions, the protrusions adhere tightly to the outer circumference of the cable, providing a sealed passage and thus maintaining the airtightness of the device's interior. This structure plays a central role in creating a fully sealed interior space, including the multi-socket body.

[0105] In particular, the cable fixing protrusion 121 can be configured such that when heated to a specific temperature or above, the thermally reactive material melts, thereby completely sealing the gap between it and the outer circumference of the cable. At this point, the protrusion melts due to internal heat and adheres tightly to the cable, thus blocking fluid passage to the outside and converting the internal space into a suffocating space. This function is highly effective in suppressing internal spread in fire situations.

[0106] Although the cable fixing protrusion 121 appears to be a simple component in structure, it is a core element in the entire multi-outlet socket safety storage device, ensuring sealing, stability, and fire response performance simultaneously. Its practicality is maximized, especially in environments where multi-outlet sockets are used mobilely, spaces with frequent cable movement, and industrial sites with fire risks. Therefore, the cable fixing protrusion 121 goes beyond a simple fixing part, performing comprehensive protective functions.

[0107] Specific embodiments of cable fixing protrusion 121

[0108] Example 1: Radial elastic protrusion structure

[0109] In this embodiment, the cable fixing protrusion 121 is configured as a structure of multiple elastic protrusions arranged radially along the inner circumference of a circle. Each protrusion has a shape that bends outward with respect to a central axis. When the cable is inserted, the protrusions fit tightly against the outer surface of the cable, and are fixed in position by friction and restoring force. This structure can flexibly adapt to usage environments where cables are inserted from various directions.

[0110] The radial protrusions are molded from silicone, TPE (thermoplastic elastomer), or flame-retardant rubber materials, exhibiting excellent durability and resilience. Each protrusion is designed to be shorter than its internal radius and adjusted to provide appropriate elastic resistance when the cable is inserted, while preventing excessive compression. This allows for stable support of cables of various thicknesses.

[0111] The raised protrusions can be arranged 360 degrees or configured at specific angles within a range of 120 to 180 degrees, and can be optimized according to the cable insertion direction or user needs. For example, when multiple sockets are installed on a wall, they can be designed to use only the lower protrusion while leaving the upper one open. This flexible arrangement improves on-site adaptability.

[0112] Because this structure maintains a prescribed interval between the protrusions, air circulation is possible, preventing internal heat buildup and helping to reduce component damage caused by heat generated during the use of multi-socket outlets. Furthermore, it maintains its shape even with repeated cable insertion and removal, and the rounded ends of the protrusions prevent damage to the cable sheath.

[0113] The radially arranged elastic protrusions have a simple structure, are easy to mold, and are suitable for mass production. Furthermore, they require no complex mechanisms; the fixing function is achieved solely through mechanical friction, thus offering the advantage of securing cables without additional fastening components or tools. This is a highly effective method for multi-outlet socket storage devices in homes or offices.

[0114] Example 2: Oblique concave-convex friction protrusion structure

[0115] In this embodiment, the cable fixing protrusion 121 is configured as a protruding structure with an obliquely shaped concave-convex pattern. When the cable passes through the sealing portions 120 at both ends, the oblique concave-convex pattern contacts the outer surface of the cable, forming strong frictional resistance, thereby ensuring the fixing force. This structure is more effective in environments where the cable needs to be fixed in the same position for a long time.

[0116] The protrusions are not ordinary vertical projections, but rather formed at an angle of approximately 30 to 45 degrees along their length, which is selectively set depending on the cable insertion direction. The concave-convex structure consists of tiny wing-like or stepped protrusions, generating resistance in the opposite direction to the cable's intended movement. This directional friction is highly effective in preventing cable detachment.

[0117] Micro-ribbed patterns or beveled grooves are added to the raised surface to increase the coefficient of friction, thereby significantly improving contact stability with the cable sheath. This microstructure guides the cable to automatically return to its original position even if it moves under vibration or external force. This design is also applicable to wires with smooth sheaths.

[0118] This structure is suitable for industrial multi-outlet socket storage devices that require semi-permanent cable fixing, and can be applied to server rooms, communication equipment, and other environments with high reliability and fixed performance requirements. It is particularly advantageous in fixed environments where cables do not need to be replaced frequently during use.

[0119] Although the oblique concave-convex friction protrusion structure has a higher mold complexity, it can be designed to adjust the friction force and withstand external forces from all directions, thereby improving the reliability and durability of the device. In addition, a "reverse friction" function can be applied, allowing the cable to be easily inserted in only one direction while preventing it from coming loose in the opposite direction.

[0120] Example 3: Thermally Reactive Sealing Protrusion Structure

[0121] In this embodiment, the cable fixing protrusion 121 is made of a heat-reactive material, which allows the protrusion structure to melt or soften when heated to a specified temperature or above, thereby performing the function of completely sealing the cable. This method helps to automatically guide gas blockage and form an asphyxiating space in the event of a fire or overheating, thereby preventing the spread of electrical fires.

[0122] The protrusion normally performs a standard fixing function and is made of silicone or a low-melting-point thermoplastic polymer composite material. When the temperature reaches approximately 160°C or higher, the protrusion melts or shrinks and adheres tightly to the outer surface of the cable, thus completely blocking the passage. At the same time, this maximizes the effectiveness of the fire extinguishing layer 113 within the internal space.

[0123] This structure offers dual performance, capable of handling both normal and emergency situations, ensuring both stability and sealing. The raised structure is designed to maintain a fixed shape, but can flexibly change shape when heated, effectively preventing the spread of flames and smoke.

[0124] The heat-reactive sealing protrusion structure can be integrated with other manually operated fire suppression systems to function as an automated fire prevention system for multi-outlet socket storage devices. This structure is particularly advantageous in environments where immediate fire response is difficult, such as industrial sites, residential facilities, and spaces with unmanned electrical equipment.

[0125] This structure can be manufactured through integral molding or multi-layer extrusion and can be designed as a consumable component that can be replaced after a specified period of time. Furthermore, when used in conjunction with non-combustible powders or thermal insulation materials, it can be expanded into a composite safety structure.

[0126] Cutting line forming part 122

[0127] The cutting line forming portion 122 is formed as a groove structure recessed to a predetermined depth along the outer peripheral surface of the end sealing portions 120, and is configured so that the user can cut the end sealing portions 120 to the required length for customized adjustment. Multiple cutting line forming portions 122 are typically formed at predetermined intervals in a vertical or oblique shape along the extending direction of the cover body portion 110. This structure ensures the product's flexible applicability to accommodate various multi-position socket lengths.

[0128] The cutting line forming section 122 is precision-formed to have a consistent depth and width, and acts as a guide line to ensure accurate cutting. The groove's cross-section is designed as a U-shaped or V-shaped channel, and its material and thickness are adjustable, allowing it to be easily separated by cutting tools while remaining resistant to damage from daily impacts or bending. This ensures both cutting stability and durability during use.

[0129] The cutting line forming portions 122 are distributed along the entire length of the sealing portions 120 at both ends, and are configured so that the user can selectively cut only the required section. The position and shape of the cutting line are strategically configured so that the remaining structure is not damaged after cutting, and the connection with the cover body portion 110 and the internal opening and closing portion 130 is maintained. This structure takes into account factors such as the distance between multi-socket outlets and electrical equipment, and the limitations of the installation location, thereby enabling customized construction.

[0130] The cutting line forming section 122 is processed taking into account the properties of thermoplastic polymer materials and is designed to withstand the heat or pressure from the cutting tool. To minimize dust generation during cutting, a fine microfiber cutting layer can be inserted inside the groove, or texture can be added during processing to stably guide the cutting path. This structure improves the safety of cutting operations in various settings such as homes, offices, and industrial sites.

[0131] The cutting line forming section 122 is not merely a structure for changing the shape, but a customized core structure that maximizes the usability of the entire device. Since the dimensions of various multi-socket units, cable lengths, wall locations, and other installation conditions differ, the user-centric length adjustment function meets practical needs. This structure forms the basis for the significant improvement in field practicality of this invention compared to existing integrated box-type protection structures.

[0132] Hanging ring 123

[0133] The hanging ring 123 is a structure formed on the outside of the two end seals 120 and configured to fix or place the multi-socket safety storage device in various locations by means of an externally suspended mounting ring. The hanging ring 123 can be integrally formed with the cover body 110 or the two end seals 120, and has the advantage of achieving the hanging or fixing function directly without the need for additional fastening parts or clips. Therefore, it can be efficiently installed even in confined spaces such as walls, ceilings, and under tables.

[0134] Hanging rings 123 are typically formed into closed curved or open ring shapes, with their inner diameter manufactured according to standard ring specifications, thus making them suitable for various hooks or wall hanging rings. They are made of reinforced plastics or highly elastic synthetic resins that simultaneously ensure flame retardancy and rigidity, and are designed not to deform even under repeated disassembly and tensile loads. Especially when installed on walls, they require structural rigidity capable of withstanding both horizontal and vertical loads.

[0135] Hanging rings 123 are formed at selected positions on the outer peripheral surfaces of the end sealing portions 120, configured to take into account the device's center of gravity for stable fixation. Users can use the hanging rings 123 to suspend or attach the multi-socket safety storage device to desired locations, maintaining the functionality of the internal multi-sockets even when the entire device is suspended. This provides benefits such as preventing ground contamination, keeping it out of reach of children, and minimizing cord tangling.

[0136] The hanging ring 123 can be configured as a rotatable or detachable structure as needed. In this case, it can be rotated by a specified angle to adjust the direction, or removed and reinstalled in another position when necessary. In addition, to improve user convenience, the hanging ring 123 can be designed with an anti-slip material coated on the outside, or given shape memory properties to maintain its shape.

[0137] The hanging ring 123 is a component that enables the multi-socket safety storage device to be easily installed in various locations, thereby maximizing space utilization. It not only offers simple installation convenience but also enhances the overall safety and aesthetics of the device, providing users with the freedom to choose the installation method according to their own environment. In this respect, the hanging ring 123 plays a crucial role in realizing the customized safety device function pursued by this invention.

[0138] Specific composition and structure of the internal opening and closing part 130

[0139] The internal opening / closing part 130 is a functional structure capable of opening the interior of the cover body 110 and the end sealing parts 120 to the outside or maintaining a sealed state. The internal opening / closing part 130 allows for the inspection or replacement of the internal multi-socket storage device without separating it, and provides easy access for connecting cables when necessary. This improves the ease of operation and maintenance efficiency of the device.

[0140] The internal opening and closing part 130 is mainly composed of an opening cutting line forming part 131 and a magnetic opening and closing part 132, and is arranged along the extension direction, which can repeatedly open and close with the longitudinal axis of the device as a reference. The internal opening and closing part 130 is provided along the length direction on the outer peripheral surface of the device, so that the entire interior of the cover body part 110 and the two end sealing parts 120 can be opened at once, or only a part can be selectively opened.

[0141] The internal opening / closing part 130 is designed to stably maintain its open and closed state, and in particular, through its linkage with the magnetic opening / closing part 132, it ensures that it will not open or close on its own even under external impact. The internal opening / closing part 130 is structurally optimized so that when replacing or inspecting the plug of electrical equipment, the required operation can be performed without completely disassembling the device. This feature reduces fatigue caused by repeated opening and closing and increases user convenience.

[0142] The internal opening and closing part 130 can be implemented in various ways depending on the material and structure, and can be combined with various opening and closing technologies such as magnetic, zipper, and Velcro. In this invention, a magnetic opening and closing method is adopted, which has the advantages of ensuring airtightness and durability while providing ease of operation. The length of the internal opening and closing part 130 can be customized and adjusted according to the size of the device or the user environment, and can also be combined with a detachable cover or sliding structure as needed.

[0143] The internal opening and closing section 130 plays a core role in ensuring the maintainability and long-term operational efficiency of the multi-socket safety storage device. This structure is not merely for opening and closing; it works in conjunction with the magnetic opening and closing section 132, the cable tie 133, and the connecting protrusion 134 to provide a composite functional structure that assists in the overall sealing force, airtightness, and safety of the device. In particular, it allows for easy internal inspection even in an emergency while sealed, making it highly practical.

[0144] Opening cutting line forming part 131

[0145] The opening cut line forming portion 131 is a cut line formed along the outer peripheral surface of the cover body portion 110 and the two end sealing portions 120, connecting the outside and the inside, and is a reference configuration for the opening operation of the internal opening and closing portion 130. This cut line is formed along the extended length direction, allowing the user to open only the desired section or open it completely. This cut line can be achieved by thinning specific areas after the structure is integrally formed.

[0146] The opening cut line forming section 131 is formed to a predetermined depth but not completely through, thus designed to be selectively opened by external pressure or operation. This structure maintains basic sealing to prevent dust or moisture from seeping in from the outside of the device, while allowing the user to operate along the cut line only when necessary. Furthermore, the cut line is marked with dotted lines, raised areas, grooves, etc., for easy identification by the user.

[0147] The opening cut line forming part 131 is linked with the magnetic opening and closing part 132. By applying a magnetic fixing force, the closed state can be maintained. After the user opens along the cut line, they can directly check the status of the multi-socket or cable stored inside. After opening, it can also be easily resealed by the magnetic opening and closing part 132, thus ensuring structural stability even during repeated opening and closing. This magnetic linkage method ensures higher airtightness compared to ordinary zippers or Velcro.

[0148] To prevent the opening cut line forming portion 131 from accidentally opening due to external impact, reinforcing ribs or auxiliary fixing structures can be formed together at specific locations. For example, fixing members or protruding fixing flanges can be arranged at a predetermined interval on both sides of the cut line, thereby forming a structure that helps maintain opening and closing. Therefore, accidental opening can be prevented, while ensuring safety and durability.

[0149] The opening cutting line forming part 131 has functionality beyond a simple cutting structure, and is organically combined with the magnetic opening and closing part 132, the binding strap 133, and the connecting protrusion 134, thereby maximizing the flexibility and practicality of the multi-socket safety storage device. In particular, it allows for quick inspection when opened and completely blocks the external environment when sealed, a structure that helps the present invention achieve core functions not found in existing box-type structures.

[0150] Magnetic opening and closing part 132

[0151] The magnetic opening / closing part 132 is a structure continuously installed on the inner side of the opening cut line forming part 131. Utilizing the magnetic attraction force, it functions to open the interior of the cover body 110 and the sealing parts 120 at both ends to the outside or maintain a sealed state. This structure, as a magnetic fixing device that helps the user open or reseal along the cut line, prevents it from being opened due to external impact or vibration. Even under repeated use, the performance of the magnetic opening / closing part 132 does not degrade, providing a stable sealing force.

[0152] The magnetic opening / closing section 132 is formed as a structure with a continuously attached magnetized metal plate or permanent magnet, and is positioned on both sides corresponding to the opening cut line forming section 131. These magnetic components are symmetrically attracted to each other and are designed to be easily separated and reassembled by applying light force from the outside. The attraction strength of the magnets is adjusted to a level that allows the user to operate without difficulty, and can be made of general magnetic tape or neodymium magnets.

[0153] The magnetic opening / closing part 132 has a structure that not only performs a simple opening and closing function, but can also actively operate in emergency situations such as fires. When the magnetic opening / closing part 132 exceeds a preset critical temperature, the structure used to fix the magnetic component melts, thereby releasing or pressurizing the magnetic component to contact the sealing direction, thus transforming it into a form that completely blocks the internal space. This thermal reaction sealing function plays a central role in sealing the gas generated inside the device without leakage.

[0154] In addition to being attached to a flat surface, the magnetic opening / closing part 132 can also be implemented using a flexible magnet capable of adapting to curved surfaces, and can be designed to fit the curvature of the cover body. This allows for a structure that maintains the overall appearance and integrity of the device without compromising internal sealing performance. The outer side of the magnetic opening / closing part 132 can be reinforced with a sealing material that provides both dust and moisture protection, thus doubly preventing the inflow of external foreign objects.

[0155] The magnetic opening / closing part 132, as the core actuating element of the internal opening / closing part 130, is a structure that simultaneously satisfies user operability and device airtightness. Compared to zippers, buttons, hooks, etc., magnetic opening and closing methods have the advantages of low risk of damage and minimal durability loss due to repeated use, making them suitable for multi-socket safety storage devices used for extended periods. Therefore, the magnetic opening / closing part 132, as a high-functionality component, can both block external environmental hazards and maximize user convenience.

[0156] Specific embodiments of magnetic opening and closing part 132

[0157] Example 1: Planar magnetic stripe combined structure

[0158] This embodiment features a structure in which planar magnetic strips are attached along the length of both sides of the opening cut line forming portion 131. The magnetic strips attract each other magnetically, maintaining a sealed internal space. Users can easily separate the magnetic strips by hand to open the interior, and simply reattach them to restore the seal using magnetic force.

[0159] The magnetic strip is made of neodymium magnets or magnetized metal sheets and is implemented as a flexible adhesive tape. The magnet is thin and light, yet provides strong adhesion, thus minimizing thickness gain even when attached to the outer wall of a structure. Furthermore, the outer surface of the tape is finished with a silicone or PVC-based waterproof coating, making it resistant to external contamination and capable of repeated use.

[0160] The strip magnet can be continuously attached to the entire length of the opening cut line forming portion 131, or, if necessary, only a portion of the section can be set as a local magnet to achieve a variable sealing structure. This structure is simple and easy to set up, and has the advantage of being able to be implemented quickly and at low cost. It can be applied to the joint between the cover body portion 110 and the two end sealing portions 120, so that the whole can operate as a closed system.

[0161] This structure allows for adjustable magnetic strength to ensure that the magnets do not easily separate even if the internal temperature of the multi-socket rises above a specified level or is subjected to external impact. It also utilizes materials with minimal magnetic loss even at high temperatures, making it suitable for long-term use. Furthermore, it is secured solely by magnetic force, eliminating the need for additional mechanical fasteners, thus simplifying installation and maintenance.

[0162] The planar magnetic strip structure is a basic and economical magnetic opening and closing method based on magnetic adsorption, and can be widely used in multi-outlet socket storage devices for home or office use. It also offers a wide range of design options, allowing for various shapes and colors, and maintains a relatively slim profile even when sealed.

[0163] Example 2: Protruding Magnetic Clip Fixing Structure

[0164] This embodiment describes a method of arranging protruding magnetic clips at predetermined intervals inside the opening cut line forming portion 131 and fastening them to the fixing portion on the opposite side. Each magnetic clip has a snap-lock structure, providing strong sealing and fixing forces by simultaneously utilizing magnetic attraction and physical bonding. This structure can stably maintain a sealed state even under strong external vibration or tension.

[0165] Magnetic clips typically employ a structure with a magnetic core inserted inside the housing, and the exterior is finished with plastic or silicone. The clip is fixed to one side of the cut line, while the opposite side has a metal plate or a corresponding clip. They are secured with a "click" sound when magnetically attracted. This not only provides a seal but also offers the user a clear tactile feedback when opening and closing.

[0166] The clips are spaced out and can operate individually, allowing for partial inspections without opening the entire wiring harness. For example, when replacing only a specific port on a multi-pole socket or checking only a particular wire, only the corresponding clip can be opened for operation and then resealed. This improves the efficiency of maintenance management.

[0167] The protruding magnetic clips are made of heat-resistant materials to ensure that the structure is not easily deformed under high temperatures or thermal shock, and some clips use thermosetting resin or flame-retardant silicone. In addition, the strength of the magnet inside the clip can be adjusted as needed, or an insulating cover can be added to block the magnetic force from the outside.

[0168] This structure is advantageous in industrial, mobile, or high-temperature environments where both fixing and sealing forces are required, offering higher reliability and clamping strength than ordinary planar magnet structures. It is particularly effective for multi-socket devices used in vehicles, factories, and field operations where frequent vibration or shock is common.

[0169] Example 3: Thermally reactive magnetic core closed structure

[0170] This embodiment describes a structure in which the magnetic core of the magnetic opening / closing part 132, installed in the opening cutting line forming part 131, is covered with a heat-reactive material. When the internal temperature rises above a preset critical value, it can automatically switch to a closed state. Normally, the magnet remains in an attracted state. Once a high temperature is detected, the fixing part of the magnetic component softens or shrinks, thereby guiding a complete seal.

[0171] The magnetic core is positioned in a fixed location, and its outer thermally reactive coating is composed of a low-melting-point thermoplastic film or a polymer material with a low melting point. This coating does not hinder magnet attraction under normal conditions, but it physically melts or deforms at high temperatures, thereby enhancing the attraction force or pressing the magnet towards a seal. This improves the sealing strength in emergency situations, preventing smoke or gas from spreading to the outside.

[0172] This structure functions like a regular magnetic strip or magnetic clip under normal conditions. The difference lies in its automatic activation of a reinforced sealing function when the temperature rises above a specified level. In the event of an internal fire or overheating, it maximizes internal airtightness without user intervention, thereby blocking the inflow of external oxygen and inhibiting the spread of flames.

[0173] This magnetic core does not operate repeatedly but performs a one-time closed function, therefore it is designed to be replaced or inspected after each operation. This consumable structure is highly effective in environments where emergency response capabilities are prioritized, and the replacement cycle can be guided by a display device or color change for easy management.

[0174] Thermally reactive magnetic core enclosed structures can be applied to high-risk power facilities, unmanned electrical equipment, server racks, and other scenarios, and are particularly favored in areas where electrical fire response is crucial. This structure can be considered a composite safety structure that ensures higher reliability and safety not only by relying solely on magnetic force but also by incorporating thermal induction response.

[0175] Cable ties 133

[0176] The cable tie 133 is formed on one side of the sealing portions 120 at both ends, with the opening cut line forming portion 131 as a reference, and functions as an additional fixing portion to enhance the external sealing force of the device. The cable tie 133 is formed as a strip-shaped structure extending laterally for a predetermined length, and physically maintains the sealed state of the opening cut line forming portion 131 by engaging with the engaging protrusion 134 arranged in the opposite position. This structure achieves double sealing in addition to the adsorption force of the magnetic opening and closing portion 132, and is further aided by the physical fastening structure.

[0177] The strapping 133 is typically made of a material with excellent flame retardancy and tensile strength, and can be formed from a polyester-based thermoplastic polymer or a TPU-based adhesive tape. This material exhibits minimal structural deformation even with repeated tightening and loosening, and demonstrates excellent resistance to changes in heat or humidity. Even when the device shakes due to external impact or vibration, the strapping 133 prevents the cut line from accidentally opening.

[0178] Multiple strapping holes are formed in the strapping tape 133, which are arranged at predetermined intervals. The user can selectively fix the strapping holes to the connecting protrusion 134 according to the required tension, which means that it can be flexibly adjusted according to the limitations of the device's outer diameter or the installation environment. This structure not only provides fixing force, but also lays the foundation for enabling user-customized settings.

[0179] The cable ties 133 are designed to be fixed to the outer wall of the device to prevent them from shaking or falling off during use. This can be achieved through initial injection molding with the product or installation via a separate fixing component. In some embodiments, multiple connection methods such as Velcro, buttons, and hooks can be used in parallel, and they can also be designed to be detachable for easy replacement if necessary. This improves the convenience of maintenance and management for the user.

[0180] The cable tie 133 and the magnetic opening / closing part 132 overlap in function, serving to enhance the overall sealing and airtightness of the multi-socket safety storage device. This structure plays a crucial role in determining the device's stability, especially in environments with unstable external conditions or where long-term fixation is required. Therefore, the cable tie 133 is not merely a simple auxiliary structure, but also plays a vital role in comprehensively improving the overall physical safety and user-friendliness of the device.

[0181] Combined with protrusion 134

[0182] The connecting protrusion 134 is formed on the outer peripheral surface of the sealing portions 120 at both ends, with the opening cutting line forming portion 131 as a reference, and has a structure that allows it to be detachably connected to the binding hole provided in the binding tape 133. The connecting protrusion 134 prevents the cutting line from accidentally opening due to externally applied force and functions to physically maintain the sealing state of the device. This structure is designed to maintain the fixing force without deformation even under repeated opening, closing and binding operations.

[0183] The protrusions 134 extend to a predetermined height along the outer diameter direction and are arranged at predetermined intervals along the outer periphery of the end sealing portions 120. This allows the user to selectively engage the strapping holes of the strapping strap 133 with the protrusions at desired positions, thereby adjusting the tightening force. Since the user can adjust the fastening position according to the required tension, the clamping strength can be flexibly set according to changes in the diameter of the cover body 110 or the external environment.

[0184] The protrusion 134 can be formed by integral injection molding or assembled and fixed as separate components. The material used is high-hardness flame-retardant synthetic resin or reinforced plastic. To prevent damage or wear from external impacts, the surface undergoes micro-engraving or finishing treatment, and reinforcing ribs are formed at the base of the protrusion to enhance structural strength. Therefore, even in long-term use environments, the stability of the fastener can be maintained.

[0185] The protrusion 134 is typically designed as a cylindrical or semi-circular protrusion, maintaining a shape precision that allows for easy insertion into the strapping hole of the strapping tape 133 while requiring a specified force during installation and removal. In some embodiments, considering the material and coefficient of friction of the strapping hole, it can be configured by adding oblique protrusions and concave surfaces to the outer surface of the protrusion, or by adding a snap-fit ​​flange at the end of the protrusion to enhance the bonding force. This structure helps users operate stably during installation and removal, avoiding misoperation.

[0186] The protrusion 134, the strapping 133, and the magnetic opening / closing part 132 together form a stable opening / closing retention structure for the internal opening / closing part 130, and function as a physical fixing part to improve the sealing reliability of the device. Especially in industrial sites or mobile installation environments with unstable external environments or vibrations, it provides substantial assistance in ensuring the fixing force that the magnetic opening / closing structure alone may not be sufficient to provide. Therefore, by incorporating the protrusion 134 as a core component, the overall safety, airtightness, and user convenience of the multi-socket safe storage device are ensured.

[0187] As described above, this invention is designed to effectively block dust, foreign objects, moisture, etc., that may enter through the socket holes of a multi-socket outlet, thereby preventing electrical accidents such as leakage, electric shock, and short circuits. Traditional multi-socket outlets are directly exposed to the outside, making them susceptible to contaminant intrusion, which frequently leads to poor electrical contact and overheating. This invention, through its multi-layered structure of the cover body 110, the sealing parts at both ends 120, and the internal opening and closing part 130, blocks direct contact with the external environment, maintains an airtight storage state, and fundamentally eliminates the dangerous factors associated with traditional exposed structures.

[0188] Furthermore, this invention provides a structure that solves the problem of inconvenience in using existing box-type multi-socket protective covers, namely the cumbersome operation of opening and closing the cover every time the multi-socket is used. The internal opening and closing part 130 is provided with a magnetic opening and closing part 132 and a binding strap 133, allowing users to easily and repeatedly open and close the cover without disassembling the entire device, enabling them to replace the internal multi-socket or connect plugs. This significantly improves operational convenience in practical use environments, maximizing efficiency in places where frequent connection and disconnection of electrical equipment is required.

[0189] Traditional protective cases, due to their fixed size and structure, have limitations in adapting to various installation environments. This invention, however, utilizes a cutting line forming part 122 to allow users to cut the sealing parts 120 at both ends to the required length, thus flexibly adapting to various multi-socket specifications and installation spaces. This customized structure enables flexible on-site installation and offers significant advantages in terms of compatibility and scalability with existing equipment.

[0190] Traditional technologies have also failed to adequately address the protection of cable passage points. However, the cable-fixing protrusion 121 of this invention adheres tightly to the outer circumference of the cable, providing a fixing force while simultaneously preventing the intrusion of external contaminants. In particular, when heated to a specified temperature or higher, the cable-fixing protrusion melts and completely seals the area around the cable, creating a suffocating space that prevents the generation of internal gases. This function is a crucial safety feature not found in traditional structures.

[0191] Furthermore, the fire extinguishing layer 113 of this invention is designed to release the built-in fire extinguishing agent when the internal temperature rises above a set critical value, thereby suppressing fires in their early stages. Traditional storage devices only provide simple shielding, while this invention, through its built-in autonomous fire extinguishing function capable of responding to fire risks, significantly reduces the possibility of electrical fires spreading. This is a highly effective technical means to minimize personal injury and property damage.

[0192] Regarding ease of external installation, this invention also overcomes the limitations of traditional technologies. Through the hanging rings 123 located on the outer sides of the sealing portions 120 at both ends, the multi-socket safety storage device can be easily installed or hung in desired locations such as on walls, ceilings, and under tables, and the fixing points can be freely set. This helps reduce restrictions on device installation and improves space utilization in various environments. It achieves a flexible installation method that is difficult to realize in traditional fixed box structures.

[0193] In summary, this invention substantially solves the problems of contaminant intrusion, inconvenient operation, size limitations, and lack of fire response capabilities in traditional technologies by providing safer protection for multi-outlet sockets and enabling them to flexibly adapt to operation in various environments. The multi-outlet socket safety storage device of this invention, which combines structural stability and functional adaptability, has been recognized as a technological advancement that improves the safety and efficiency of electrical equipment use.
