Description

A detachable and assembleable children's playpen component Technical Field

[0001] This invention relates to the field of child safety protection equipment technology, and in particular to a child safety fence component that can be disassembled and assembled. Background Technology

[0002] Child safety barriers are relatively safe play areas set up within children's activity zones to ensure their safety and prevent them from running around and causing accidents.

[0003] Existing child safety playpen components generally employ fixed connections or monolithic structures, resulting in bulky and difficult-to-compress items during transportation. This occupies excessive storage and logistics space, significantly increasing transportation and storage costs. Installation typically relies on specialized tools such as screwdrivers or wrenches, requiring users to follow complex steps to secure each component individually—a cumbersome and time-consuming process difficult for ordinary households to complete independently. After disassembly, the playpen cannot be flexibly adjusted in length or reassembled to suit specific space needs, leading to non-reusable materials and unnecessary resource waste. Furthermore, the monolithic structure limits the playpen's adaptability, making it difficult to accommodate uneven ground or spatial variations in different home environments, posing safety hazards and reducing ease of use. Users frequently encounter problems such as mismatched playpen sizes, assembly difficulties, and the need for disassembly and disposal, severely impacting daily user experience and efficiency.

[0004] In summary, existing child safety barriers suffer from cumbersome assembly and disassembly, and poor flexibility in use. Summary of the Invention

[0026] Traditional existing fence components take up a lot of space during transportation, increasing logistics costs; installation requires professional tools and complex procedures, and it is difficult to flexibly adjust the length or reassemble them after disassembly, resulting in resource waste and insufficient ease of use.

[0027] Based on this, as shown in Figures 1 to 3, the present invention provides a detachable and assembleable children's fence component, including: multiple fence structures 1, which are arranged sequentially end to end; and a connecting structure 2, which is disposed between two adjacent fence structures 1 for detachable installation of the two adjacent fence structures 1.

[0028] It should be noted that the fence structure 1, which constitutes the main part of the children's fence, is usually designed as a panel, mesh, or frame structure. Its main function is to limit the children's activity area and ensure their safety. The materials for the fence structure 1 are diverse, such as plastic, wood, or metal, and its size and height can be adjusted according to the child's age and specific usage scenario.

[0029] The connecting structure 2 serves to enable a detachable connection between adjacent fence structures 1. Through the connecting structure 2, fence structures 1 can be easily assembled or disassembled, allowing for flexible configuration and transportation of the entire fence. The connecting structure 2 can employ various mechanical connection methods, such as clips, pins, bolts, or hinges.

[0030] This embodiment provides a detachable and assembleable children's playpen component, characterized by the arrangement of multiple playpen structures 1 and connecting structures 2.

[0031] Specifically, multiple fence structures 1 are designed to be arranged sequentially, end to end. As one implementation, the sides of each fence structure 1 can be designed with straight edges, allowing adjacent fence structures 1 to fit tightly together, forming a continuous enclosure surface. Alternatively, the fence structure 1 can be designed as units with specific geometric shapes, such as L-shapes or arcs, to adapt to different spatial layout requirements. When arranged end to end, the connecting ends of these units are designed with matching shapes to ensure the stability and integrity of the connection.

[0032] The connecting structure 2 is located between two adjacent fence structures 1, and its main function is to allow for the detachable installation of the two adjacent fence structures 1. One implementation is a simple pin mechanism, where one fence structure 1 has a socket on its side, and the other fence structure 1 has a pin on its side that mates with the socket. The fence structures 1 can be connected or separated by manually inserting or removing the pin. Alternatively, the connecting structure 2 can use a bolt and nut combination, where bolts are passed through pre-drilled holes on adjacent fence structures 1 and nuts are tightened for fixation. Disassembly is achieved simply by loosening the nuts. Furthermore, the connecting structure 2 can also employ a simple snap-fit ​​design, where one fence structure 1 has a protrusion on its edge, and the other fence structure 1 has a groove on its edge. The protrusion engages with the groove by pressing or sliding, thus achieving the connection.

[0033] This application employs multiple detachable and assembleable fence structures 1 and detachable connection structures 2, enabling the fence components to be disassembled into independent units during transportation, significantly reducing space occupation and logistics costs. Simultaneously, its installation process requires no specialized tools, is simple to operate, and achieves rapid assembly and disassembly. Therefore, the component can be flexibly adjusted in length and shape according to actual needs, improving reusability and ease of use, and effectively avoiding the resource waste problem of traditional fence components.

[0034] In some embodiments of the present invention, the fence structure 1 is rectangular or L-shaped. A rectangular fence structure is suitable for constructing straight-line fences, while an L-shaped fence structure facilitates corner connections and adapts to room corners or irregular layouts. By combining fence structures 1 of different shapes, various enclosure forms such as squares, polygons, or U-shapes can be created, improving spatial adaptability.

[0035] As shown in Figure 3, in some embodiments of the present invention, the fence structure 1 is rectangular and includes an outer frame 101 and a plurality of longitudinal supports 102 disposed within the outer frame 101; the plurality of longitudinal supports 102 are distributed at intervals along the length direction of the outer frame 101.

[0036] Specifically, the outer frame 101 is a structural component that forms the main outline of the fence structure 1. Its main function is to provide basic shape support and structural rigidity for the entire fence structure 1. The outer frame 101 can be made of various materials, such as high-strength plastics (e.g., HDPE, ABS), metal profiles (e.g., aluminum alloy, steel), or wood. Its cross-sectional shape can be rectangular, circular, or irregular to adapt to different design requirements and strength requirements.

[0037] In this application, the outer frame 101 is described as rectangular. The size and thickness of the outer frame 101 should be sufficient to withstand the pushing, pulling, and impact forces that children experience during daily use, ensuring the overall stability of the fence.

[0038] Longitudinal supports 102 are vertical support members installed inside the outer frame 101. The main function of these supports is to enhance the internal strength of the fence structure 1, preventing the fence panels from bending or deforming under stress. Simultaneously, the longitudinal supports 102, through their spaced distribution, form a series of gaps. These gaps should be designed to meet child safety standards, effectively preventing children from passing through the fence while also preventing children's heads or limbs from getting stuck. The material of the longitudinal supports 102 can be the same as or different from that of the outer frame 101, for example, using plastic rods, metal pipes, or wooden strips. Their number and spacing can be optimized according to the fence's size, required strength, and safety regulations.

[0039] Through the above technical solution, the fence structure 1 provides robust external support and a clearly defined structural boundary through the outer frame 101. Meanwhile, the numerous longitudinal supports 102 located within the outer frame 101 not only significantly enhance the overall deformation resistance and stability of the fence structure 1, effectively solving the potential strength deficiency problem of a single plate-like structure, but also, with the longitudinal supports 102 spaced along the length of the outer frame 101, form a protective barrier that meets safety standards, effectively preventing children from passing through or climbing the fence, thereby greatly improving the safety of the children's fence components. Furthermore, this structural design also provides good visibility, allowing parents to easily observe their children's activities, thus balancing practicality and safety.

[0040] As shown in Figures 1 to 6, in some embodiments of the present invention, the connecting structure 2 includes at least one locking element 3.

[0041] The locking element 3 is a mechanical structure used to securely connect adjacent fence structures 1 together. Its main function is to provide an active and reliable locking mechanism to prevent accidental separation of the fence structures 1 under external force, thereby ensuring the overall stability and safety of the child fence assembly. The locking element 3 can be implemented in various forms; for example, it can be a snap-fit ​​mechanism that locks through elastic deformation; it can be a bolt or screw mechanism that tightens through threaded engagement; or it can be a pin mechanism that limits movement through insertion. In some embodiments, the locking element 3 can be designed to require specific operation to unlock, preventing children from disassembling it themselves, thereby improving safety. For example, the locking element 3 can be designed to require pressing two buttons simultaneously or rotating a specific angle to unlock, increasing the difficulty for children to operate. The number of locking elements 3 can be adjusted according to actual connection needs; for example, one locking element 3 can be provided at each of the upper and lower ends of the connecting structure 2 to provide a more uniform and secure locking effect.

[0042] By incorporating at least one locking element 3 in the connecting structure 2, an active and reliable locking mechanism can be provided for adjacent fence structures 1. This solves the problem of unstable connections and easy accidental separation that may result from simple connections relying solely on the connecting structure 2. The presence of the locking element 3 ensures that the fence structures 1 can be firmly fixed together after assembly, effectively preventing accidental disassembly of the fence components even under external forces such as children pushing, pulling, or climbing, thereby significantly improving the overall stability and safety of the child fence components. Furthermore, through the reasonable design of the locking element 3, a child-proof function can also be implemented, further ensuring children's safety.

[0043] As shown in Figures 1 to 6, in some embodiments of the present invention, the locking member 3 is a U-shaped structure with its opening facing the fence structure 1. A first limiting groove 105 that cooperates with the locking member 3 is provided at the corner of the fence structure 1. Two connecting frames 301 are provided in the opening end of the locking member 3, and the two connecting frames 301 are distributed at intervals along the length direction of the locking member 3. A first notch 103 is provided in the first limiting groove 105, and a first boss 104 that cooperates with the connecting frame 301 is provided in the first notch 103.

[0044] Specifically, the locking member 3 is designed in a U-shape, with its opening facing the fence structure 1 to be connected. This U-shaped structure can initially engage with specific parts of the fence structure 1 in a wrapping or encircling manner, thus providing initial positioning and support. Its shape helps guide the fence structure 1 into the correct installation position and provides a stable foundation for the subsequent locking mechanism. A first limiting groove 105 is provided at the corner of the fence structure 1. The shape and size of this limiting groove 105 match the U-shaped structure of the locking member 3 to precisely accommodate it. This engagement ensures high positioning accuracy and structural stability in the connection between the locking member 3 and the fence structure 1, preventing the connector from shifting or shaking under stress.

[0045] Inside the opening of the locking member 3, two connecting frames 301 are provided. These two connecting frames 301 are spaced apart along the length of the locking member 3. As key connecting components on the locking member 3, the connecting frames 301 primarily provide interfaces for engaging or embedding with corresponding structures on the fence structure 1, thus forming a more robust mechanical connection. Their spaced distribution helps to disperse connection stress and provide multi-point support. Inside the first limiting groove 105 of the fence structure 1, a first notch 103 is further provided. Within this first notch 103, a first boss 104 is provided. The shape and size of the first boss 104 are designed to fit tightly with the connecting frames 301 within the locking member 3. When the locking member 3 is connected to the fence structure 1, the connecting frames 301 can be fitted over the first boss 104, forming an interlocking structure. This boss-frame engagement mechanism is the core of achieving a stable connection between the fence structures 1; it effectively resists tensile and shear forces, preventing accidental separation of the fence under external forces.

[0046] Through the above technical solution, the locking component 3 is designed as a U-shaped structure with its opening facing the fence structure 1, and it cooperates with the first limiting groove 105 at the corner of the fence structure 1, achieving initial positioning and stable connection between the locking component 3 and the fence structure 1. Based on this, the two connecting frames 301 inside the opening end of the locking component 3 form a precise engaging connection with the first protrusion 104 in the first notch 103 inside the first limiting groove 105. The two connecting frames 301 are respectively used to fit around the outside of the first protrusion 104 on two adjacent fence structures 1, realizing the connection between the two adjacent fence structures 1.

[0047] This multi-layered cooperation and interlocking mechanism not only significantly improves the stability and reliability of the connections between the fence structures 1, effectively preventing accidental loosening or separation during children's activities, but also makes the assembly process more intuitive and convenient through the guiding effect of the U-shaped structure and limiting grooves, reducing installation difficulty. At the same time, this design also facilitates subsequent disassembly, ensuring the overall performance of the child fence components in terms of safety and ease of use.

[0048] As shown in Figures 1 to 8, in some embodiments of the present invention, a connecting block 302 is provided on the inner sidewall of the locking member 3; a first mounting groove 106 corresponding to the position of the connecting block 302 is provided on the fence structure 1 to cooperate with the connecting block 302.

[0049] Specifically, the connecting block 302 is a protruding structure disposed on the inner sidewall of the locking member 3. Its main function is to engage with the first mounting groove 106 on the fence structure 1, thereby providing additional locking force and enhancing the connection stability between the locking member 3 and the fence structure 1. The connecting block 302 can be designed in various shapes, such as rectangular, trapezoidal, circular, semi-circular, or with barbs, to optimize its engagement effect and ease of disassembly. In this application, the connecting block 302 is preferably circular.

[0050] Its material is typically the same as that of the locking element 3 to ensure sufficient strength and durability. The first mounting groove 106 is formed in the fence structure 1 to accommodate and mate with the connecting block 302. The shape and size of the first mounting groove 106 match the connecting block 302 to ensure a tight engagement. When the connecting block 302 is inserted into the first mounting groove 106, it restricts the lateral and longitudinal movement of the locking element 3 relative to the fence structure 1, thereby further securing the connection. The first mounting groove 106 can be formed in the fence structure 1 by machining.

[0051] Through the above technical solution, when the locking member 3 is connected to the fence structure 1, the connecting block 302 on the inner wall of the locking member 3 can be inserted into and engaged in the first mounting groove 106 on the fence structure 1. This engagement provides an additional locking point for the original connection mechanism, effectively enhancing the connection strength between the locking member 3 and the fence structure 1, and significantly reducing the risk of loosening or accidental detachment under external forces. Therefore, this solution can improve the overall structural stability of the child fence assembly and ensure the safety of children during use.

[0052] As shown in Figures 1 to 8, in some embodiments of the present invention, there are two connecting blocks 302, and the two connecting blocks 302 are respectively disposed on the left side wall and the right side wall of the locking member 3.

[0053] Specifically, in each locking component 3, a connecting block 302 located on the left or right side wall is connected to the fence structure 1, forming a single-side, single-point connection. This connection method ensures a stable connection between the locking component 3 and the fence structure 1, while also facilitating disassembly when needed. It effectively avoids difficulties in installation or disassembly caused by multiple constraints during installation or disassembly, thereby reducing potential structural damage to the locking component 3 or the fence structure 1.

[0054] The connecting block 302 is a protruding structure located on the inner wall of the locking member 3. Its shape can be designed as rectangular, trapezoidal, circular, semi-circular, or with barbs, etc. In this embodiment, a circular shape is preferred to balance the firmness of engagement and the ease of disassembly. The material of the connecting block 302 is generally the same as that of the locking member 3 body to ensure sufficient structural strength and durability.

[0055] A first mounting groove 106 is provided on the fence structure 1 at the position corresponding to the connecting block 302. The shape and size of the groove match the connecting block 302, so that the connecting block 302 can be inserted and engaged in the first mounting groove 106. The first mounting groove 106 can be formed on the fence structure 1 by machining. Its cooperation with the connecting block 302 can limit the lateral and longitudinal displacement of the locking member 3 relative to the fence structure 1, providing an additional locking function.

[0056] With the above structure, when the locking component 3 is installed on the fence structure 1, the connecting block 302 and the first mounting groove 106 form a reliable engaging connection, which not only enhances the connection stability between the locking component 3 and the fence structure 1, but also makes assembly and disassembly easier due to the single-point connection design, which is conducive to maintenance and operation and extends the service life of the components, thereby improving the overall safety and ease of use of the children's fence.

[0057] As shown in Figures 1 to 8, in some embodiments of the present invention, an inclined notch 303 is provided on the side of the connecting block 302 near the fence structure 1.

[0058] The connecting block 302 is a protruding structure on the inner wall of the locking member 3. Its main function is to allow the locking member 3 to be inserted into the corresponding first mounting groove 106 on the fence structure 1 when connected to the fence structure 1, thereby achieving mechanical fixation and limiting of the two. The connecting block 302 is usually integrally formed with the locking member 3 or fixed in a reliable manner to ensure the stability of the connection. Its shape and size design must match the first mounting groove 106 to ensure a tight fit. The inclined notch 303 is an inclined structure on the connecting block 302 near the fence structure 1. The function of the inclined notch 303 is to provide guidance and buffering during the insertion of the connecting block 302 into the first mounting groove 106. Specifically, when the connecting block 302 contacts the first mounting groove 106, the inclined notch 303 can guide the connecting block 302 to smoothly enter the first mounting groove 106, reducing direct collision and jamming. Furthermore, the inclined notch 303 can also generate a certain amount of elastic deformation or compression during the connection process through the inclined surface effect, making the connection smoother and facilitating easier separation during disassembly. The inclination angle and depth of the inclined notch 303 can be designed according to actual application requirements to balance the convenience and stability of the connection.

[0059] Through the above technical solution, an inclined notch 303 is provided on the side of the connecting block 302 near the fence structure 1. When the locking member 3 is assembled with the fence structure 1, the inclined notch 303 can serve as a guide surface, allowing the connecting block 302 to slide more smoothly into the first mounting groove 106 on the fence structure 1. This design effectively avoids possible hard collisions or jamming between the connecting block 302 and the first mounting groove 106, thereby significantly reducing the force required for assembly and improving the convenience and efficiency of installation. Therefore, the design of the inclined notch 303 greatly optimizes the connection experience between the fence structure 1 and the locking member 3, making the assembly and disassembly of the children's fence components more effortless and smooth.

[0060] As shown in Figures 1 to 9, in some embodiments of the present invention, the front end and rear end of the locking member 3 are bent inward to form a U-shaped limiting piece 304; a second limiting groove 107 that cooperates with the U-shaped limiting piece 304 is provided in the first limiting groove 105 on the fence structure 1.

[0061] Specifically, the U-shaped limiting piece 304 refers to the U-shaped structure formed by bending the front and rear ends of the locking member 3 inward. This structure is usually formed by integral molding or subsequent bending processing, and its main function is to provide additional limiting and fixing functions. The U-shaped limiting piece 304 can be directly extended and bent from the body material of the locking member 3, for example, by injection molding or metal sheet stamping and bending. Its bending angle and the size of the U-shaped opening can be designed according to actual needs to ensure a tight fit with the mating structure. The inner edge of the limiting piece 304 can be designed to have a smooth transition to avoid injury to children during use. The second limiting groove 107 is a groove opened inside the first limiting groove 105 on the fence structure 1, and its shape and size match the U-shaped limiting piece 304. The second limiting groove 107 is usually formed at the corresponding position of the fence structure 1 by molding or machining. It can be a rectangular groove, an arc groove, or other groove shape that matches the shape of the U-shaped limiting piece 304. When the U-shaped limiting piece 304 is inserted into the second limiting groove 107, a tight fit is formed between the two, thereby restricting the axial and radial movement of the locking member 3 relative to the fence structure 1, further enhancing the stability of the connection. The depth and width of the second limiting groove 107 should be precisely designed to ensure that the U-shaped limiting piece 304 can be smoothly inserted and effectively limited, while avoiding over-tightening that would make disassembly difficult.

[0062] Through the above technical solution, U-shaped limiting pieces 304 that bend inward are provided at both the front and rear ends of the locking member 3, and a second limiting groove 107 that cooperates with the U-shaped limiting piece 304 is opened in the first limiting groove 105 on the fence structure 1. When the locking member 3 is connected to the two fence structures 1, the two U-shaped limiting pieces 304 can be inserted into and engaged in the second limiting groove 107 of the two fence structures 1 respectively, so as to realize the connection of the locking member 3 to the two adjacent fence structures 1.

[0063] This dual-limiting structure, namely the cooperation between the U-shaped limiting piece 304 and the second limiting groove 107, further enhances the connection strength and stability between the locking member 3 and the fence structure 1, based on the initial positioning provided by the connecting frame 301 and the first boss 104. It effectively restricts the relative movement of the locking member 3 in the connection direction, preventing loosening or detachment due to accidental impacts or children pushing or pulling, thereby significantly improving the overall safety and reliability of the child fence assembly and providing children with a more stable and safer play environment.

[0064] As shown in Figures 1 to 9, in some embodiments of the present invention, both ends of the U-shaped limiting piece 304 are bent inward to form locking hooks 305; a locking groove 108 that cooperates with the locking hooks 305 is provided in the second limiting groove 107.

[0065] Specifically, the locking hook 305 is a structural extension of the U-shaped limiting piece 304, formed by bending the open end of the U-shaped limiting piece 304 inward. Its shape is typically hook-shaped or barbed. This structural design allows the locking hook 305 to form a snap-fit ​​or hook-like relationship with the corresponding slot during insertion or engagement, thus providing a positive locking force. The locking hook 305 can be made of a material with a certain degree of toughness, allowing for slight deformation and smooth insertion during installation, and maintaining a stable hook state after locking. Its function is to enhance the strength of the connection and prevent the fence structure 1 from accidentally detaching under external force.

[0066] Meanwhile, the locking groove 108 is a groove of a specific shape set inside the second limiting groove 107, whose geometry and shape precisely match the locking hook 305. When the locking hook 305 is inserted into the second limiting groove 107, the locking hook 305 can smoothly enter and engage in the locking groove 108. The locking groove 108 is typically designed to accommodate the locking hook 305 and provide a locking point to prevent the locking hook 305 from disengaging without external intervention.

[0067] Through the above technical solution, based on the initial limiting provided by the U-shaped limiting piece 304, an inwardly bent locking hook 305 is provided at the open end of the U-shaped limiting piece 304, and a locking groove 108 is opened in the second limiting groove 107 to cooperate with the locking hook 305. When the locking member 3 is connected to the fence structure 1, the locking hook 305 can elastically snap into the locking groove 108. This snap-fit ​​cooperation method further forms a positive mechanical lock, effectively preventing the fence structure 1 from detaching when subjected to accidental impact or pushed or pulled by children. This design significantly enhances the connection firmness and stability between the fence structure 1 and the connecting structure 2, reduces the risk of accidental disintegration of the fence, and thus improves the overall safety performance and reliability of the child fence assembly.

[0068] As shown in Figures 1 to 6, in some embodiments of the present invention, the fence structure 1 is provided with rounded chamfers on all four sides; the locking member 3 is recessed inward at the center to form a limiting recess 306 that matches the rounded chamfers on the fence structure 1.

[0069] Specifically, the fence structure 1 has rounded chamfers on all four sides, meaning that all external edges and corners of the fence structure 1 are designed with smooth, curved transitions rather than sharp right angles. This rounded chamfer design aims to eliminate any potential sharp edges, thereby significantly improving the safety of the child fence components and effectively preventing scratches or abrasions caused by collisions or friction when children touch or play with them. The specific radius of the rounded chamfer can be adjusted according to actual needs and safety standards, usually achieved through molding or subsequent processing to ensure the smoothness and consistency of the edges. Simultaneously, a limiting recess 306 is formed inwardly at the center of the locking member 3, and the shape and size of this limiting recess 306 precisely match the rounded chamfer on the fence structure 1. When the locking member 3 is connected to the fence structure 1, the rounded chamfer of the fence structure 1 can be tightly embedded into the limiting recess 306 of the locking member 3. This fitting method not only provides additional positioning and limiting functions between the fence structure 1 and the locking component 3, ensuring the stability and precision of the connection, but also helps guide the alignment of components during assembly, making the connection process smoother and more convenient. The limiting recess 306 is usually integrally formed by the mold of the locking component 3 to ensure its fitting accuracy with the rounded chamfer.

[0070] By employing the aforementioned technical solution, rounded chamfers are incorporated around the perimeter of the fence structure 1, effectively eliminating any potentially sharp edges and significantly enhancing the safety of the child fence components, thereby reducing the risk of accidental injury to children during use. Simultaneously, the locking element 3 features an inwardly recessed center that mates with the rounded chamfers on the fence structure 1, creating a limiting recess 306 that ensures a tighter and more precise fit between the locking element 3 and the fence structure 1 during connection. This fit not only improves the stability and reliability of the connection, preventing wobbling or loosening at the joint, but also makes the assembly process smoother, reducing obstacles caused by misalignment, thus enhancing the user experience and the overall aesthetics of the product.

[0071] As shown in Figures 1 to 11, in some embodiments of the present invention, at least one side of the connecting frame 301 is provided with a reinforcing rib 307; the reinforcing rib 307 is fixedly disposed on the inner side wall of the locking member 3.

[0072] Specifically, the reinforcing rib 307 is a structural component used to enhance the rigidity and strength of a structure. It typically exists in the form of a protrusion or rib, increasing the bending and torsional resistance of the component and dispersing stress by increasing the moment of inertia of the cross-section. In this application, the main function of the reinforcing rib 307 is to enhance the structural strength and stability of the connecting frame 301, preventing deformation or breakage under load. The reinforcing rib 307 can be integrally formed on the side of the connecting frame 301, for example, through injection molding or die casting. Its shape can be straight, wavy, or grid-like, depending on the desired reinforcement effect and manufacturing process. The size and quantity of the reinforcing rib 307 can be designed according to the stress conditions and material properties of the connecting frame 301 to ensure it can effectively resist the connecting force from the fence structure 1. The reinforcing rib 307 is fixed to the inner wall of the locking member 3, ensuring that the reinforcing rib 307 can effectively transfer the force of the connecting frame 301 to the inner wall of the locking member 3, forming a more stable overall structure. By connecting the reinforcing rib 307 to the inner wall of the locking member 3, the deformation resistance of the connecting frame 301 can be further improved, and relative displacement or loosening of the connecting frame 301 under stress can be prevented. The reinforcing rib 307 can be integrally formed with the inner wall of the locking member 3, for example, during injection molding or die casting of the locking member 3, the reinforcing rib 307 can be formed simultaneously and connected to the inner wall.

[0073] Through the above technical solution, reinforcing ribs 307 are provided on at least one side of the connecting frame 301 and fixed to the inner wall of the locking member 3, significantly enhancing the structural strength and rigidity of the connecting frame 301. When the fence structure 1 engages with the connecting frame 301 via the first boss 104, the connecting force borne by the connecting frame 301 can be effectively dispersed and transmitted to the inner wall of the locking member 3 through the reinforcing ribs 307, thereby effectively resisting the deformation or damage that may occur to the connecting frame 301 under stress. This not only improves the connection stability and reliability of the fence components and extends their service life, but also ensures that the child fence remains stable during long-term use, enhancing product safety.

[0074] As shown in Figures 10 and 11, in another embodiment of the present invention, the connecting structure 2 includes two locking members 3, which are located at the top and bottom of the fence structure 1, respectively.

[0075] Among them, the locking member 3 located at the bottom of the fence structure 1 has a through hole 308 at the position corresponding to the connecting frame 301. The through hole 308 is used to accommodate the first boss 104.

[0076] Specifically, a perforation 308 is provided on the locking member 3 located at the bottom of the fence structure 1, and its position corresponds to that of the connecting frame 301. This perforation 308 is not for connection, but rather provides an opening for the first boss 104 to extend into or align with. For example, the perforation 308 can be a circular, square, or irregularly shaped hole, the size and shape of which match the shape of the first boss 104 to ensure that the first boss 104 can be accurately positioned and mate with the perforation 308.

[0077] Simultaneously, the bottom surface of the first boss 104 is on the same horizontal line as the edge of the perforation 308 or the bottom surface of the locking member 3, or the top surface of the first boss 104 is flush with the edge of the perforation 308. This ensures that the first boss 104 can directly or indirectly bear the vertical load of the fence structure 1 after connection. For example, the first boss 104 can completely pass through the perforation 308 and be flush with the bottom surface of the locking member 3, or the lower surface of the first boss 104 can be flush with the lower edge of the perforation 308, thus forming a stable support point. This function is achieved through the flush fit between the first boss 104 and the perforation 308. When the fence structure 1 is connected by the locking member 3, the first boss 104 located at the bottom of the fence structure 1 no longer merely cooperates with the connecting frame 301 for lateral positioning, but through its flush setting with the perforation 308, it directly or indirectly transfers the vertical weight of the fence structure 1 to the locking member 3, and then to the ground.

[0078] Through the above technical solution, a through hole 308 is made in the locking member 3 located at the bottom of the fence structure 1, and the first boss 104 on the fence structure 1 is flush with the through hole 308, thus achieving effective support for the fence structure 1. When the fence structure 1 is installed in place, the first boss 104 at its bottom can directly or indirectly form a stable contact surface with the through hole 308 on the locking member 3, thereby evenly transferring the vertical load of the fence structure 1 to the locking member 3, and finally to the ground. This design significantly enhances the load-bearing capacity and overall stability of the bottom of the fence assembly, effectively preventing the fence structure 1 from sinking, deforming, or loosening due to long-term stress or external impact, and improving the safety and durability of the child fence assembly.

[0079] As shown in Figures 10 and 11, in some embodiments of the present invention, at least two observation holes 309 are also provided on the locking member 3, and the observation holes 309 are used to observe the assembly of the fence structure 1.

[0080] Specifically, the observation hole 309 is a through hole provided on the locking member 3. Its main function is to provide a visual channel to observe the interior of the locking member 3 or its connection status with the fence structure 1. The observation hole 309 can be designed as circular, square, elliptical or other geometric shapes. Its size should be sufficient to allow the human eye to clearly observe the internal connection, while not being too large to affect the structural strength of the locking member 3.

[0081] The observation hole 309 can be formed on the wall surface of the locking member 3 by injection molding, drilling, or stamping. Its location should be chosen in a key area that effectively reflects the assembly status of the fence structure 1, such as the mating point between the connecting frame 301 and the first boss 104, or the engagement point between the locking hook 305 and the locking groove 108. The design of at least two observation holes 309 indicates that there can be multiple observation holes 309 distributed at different locations on the locking member 3 to provide observation points from multiple angles or locations, thereby more comprehensively confirming the assembly status. For example, one observation hole 309 can be used to observe the mating of the connecting frame 301 and the first boss 104, and another observation hole 309 can be used to observe the positioning of the U-shaped limiting piece 304 or the locking hook 305. The observation hole 309 is used to observe the assembly of the fence structure 1; this feature clarifies the functional purpose of the observation hole 309, namely, to assist users or installers in judging whether the connection between the fence structure 1 and the locking member 3 is correct and complete. When the fence structure 1 is inserted into the locking member 3, the observation hole 309 allows direct observation of whether the connecting frame 301 is aligned with and engaged with the first boss 104, or whether the locking hook 305 is fully engaged in the locking groove 108. If the assembly is correct, the expected connection status can be observed through the observation hole 309, such as color changes, alignment, or the appearance of specific indicator marks. This provides an intuitive visual feedback mechanism, avoiding the uncertainty that may arise from relying solely on touch or experience.

[0082] Through the above technical solution, at least two observation holes 309 are provided on the locking component 3, allowing the operator to directly observe the mating status of the internal connecting parts through these observation holes 309 when the fence structure 1 is connected to the locking component 3. This intuitive visual feedback mechanism greatly improves the accuracy and reliability of assembly. The operator no longer needs to rely on guesswork or feel, but can clearly confirm whether the fence structure 1 has been completely and correctly installed, thereby effectively avoiding safety hazards such as fence loosening or falling off due to improper assembly. At the same time, the design of multiple observation holes 309 provides a more comprehensive observation perspective, further ensuring the firmness of the connection and improving the overall safety and user experience of the child fence assembly.

[0083] As shown in Figures 1 to 9, in some embodiments of the present invention, the lower end of the fence structure 1 is also provided with an anti-slip pad 109.

[0084] Anti-slip pad 109 is a component used to increase friction and prevent objects from sliding. Its main function is to increase the coefficient of friction between the fence structure 1 and the ground, thereby effectively preventing the child fence components from sliding or shifting during use. Specifically, the anti-slip pad 109 can be made of materials with a high coefficient of friction, such as rubber, silicone, polyurethane, and other elastomers. These materials can form good contact with the ground, generating sufficient static friction to resist external pushing forces or the tendency to slide caused by children's activities. The installation method of the anti-slip pad 109 can be varied. For example, it can be firmly fixed to the lower end of the fence structure 1 by adhesive; it can also be made using a snap-fit ​​structure or screw connection, making it detachable or replaceable. The shape and size of the anti-slip pad 109 can be adjusted according to the bottom design of the fence structure 1 and actual anti-slip requirements. For example, it can be designed as a circle, square, strip, or irregular shape, and can be evenly distributed along the lower end of the fence structure 1 or placed at key stress points.

[0085] By employing the aforementioned technical solution, an anti-slip pad 109 is installed at the lower end of the fence structure 1, significantly increasing the friction between the child fence component and the ground. This allows the fence to maintain a stable position when pushed or pulled by children or moved by itself, effectively preventing the fence from sliding or shifting on smooth surfaces. This greatly improves the overall stability and safety of the child fence component, providing children with a more stable and safer activity space.

[0086] In another embodiment of the invention, multiple fence structures 1 are designed to be arranged sequentially, end to end. Specifically, the side of each fence structure 1 can be designed as a straight edge, allowing adjacent fence structures 1 to fit tightly together and form a continuous enclosure surface. Furthermore, the fence structure 1 can also be designed as a unit with a specific geometric shape, such as an L-shape or an arc, to adapt to different spatial layout requirements. When arranged end to end, the connecting ends of these units are designed with matching shapes to ensure the stability and integrity of the connection.

[0087] Furthermore, the fence structure 1 can also adopt a modular design, that is, by flexibly configuring various functional modules inside the fence structure 1, such as climbing components, slide units, and educational game panels, a rich variety of children's play modules can be formed. These modules can be freely combined and adjusted according to actual needs, and finally assembled into a safe, enclosed and fully functional children's playground to meet the entertainment and activity needs of children of different ages.

[0088] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
