Description

Technical Field

[0001] This utility model relates to the field of fencing, and in particular to a single fencing unit and a folding fencing assembly. Background Technology

[0002] In contemporary society, with the acceleration of urbanization and the improvement of residents' living standards, pet ownership has shifted from traditional functional needs (such as guarding the house and catching mice) to emotional companionship needs, becoming a widely popular modern lifestyle. According to relevant industry reports, the global pet household penetration rate has exceeded 35%, with urban households exceeding 50%, and companion animals such as cats and dogs gradually becoming important family members. However, the convenience issues arising from pet ownership are becoming increasingly prominent, especially in everyday home scenarios. The risk of pets escaping due to accidentally opening doors has become a common pain point for many pet owners. In real-life scenarios, pet owners frequently face the need to temporarily open the door, such as to receive packages, pick up parcels, sign for mail, or briefly interact with people outside. These door-opening behaviors are characterized by their short duration and suddenness, typically lasting only a few seconds to tens of seconds. Furthermore, the pet owner's attention is mostly focused on the task at hand (such as checking delivery information or exchanging items), making it difficult to effectively manage the pet simultaneously. Because cats, dogs, and other pets are generally curious and active, with a strong desire to explore the outside environment, they are highly likely to rush out of the house the moment the door opens, taking advantage of the owner's inattention, leading to a series of subsequent problems. In practical terms, when pets escape from their homes, it can cause several problems. First, pet owners may have to interrupt their current activities (such as pausing deliveries or avoiding communication with people outside) to spend extra time and energy searching for and calling their pets. This not only impacts their daily lives but can also lead to safety hazards such as collisions in hallways or knocked-over items caused by chasing the pet. Second, if the pet escapes to outdoor public areas, it may face risks such as getting lost, traffic accidents, conflicts with other animals, or being difficult to find due to not wearing identification tags, causing emotional trauma and financial loss to the pet owner. Furthermore, some pets may wander into neighbors' homes or public spaces during their escape, causing neighborhood disputes and disrupting the harmony of the living environment. Current market solutions to these problems have significant limitations. For example, traditional fixed fences are bulky, complex to install, cannot flexibly adapt to different door sizes, and are inconvenient to store and carry, making them unsuitable for temporary interception. Pet leashes require constant hand-held control by the owner, rendering them unusable in situations where both hands are busy, such as opening doors or retrieving items. While smart access control systems can automatically open and close doors, they lack physical interception capabilities for pets, failing to fundamentally prevent escape. Therefore, developing a pet interception device that is simple in structure, easy to install, foldable for storage, and effectively adaptable to different door sizes is an urgent need to address current pet ownership pain points and provides crucial technical support for improving the convenience of pet owners and the safety of their pets.

[0006] A further preliminary embodiment of this utility model is as follows: the first connecting component includes a first front hook and a first rear buckle, and the second connecting component includes a second front buckle and a second rear hook, wherein the first front hook and the second rear hook are the first shaft connection fixing members, and the first rear buckle and the second front buckle are the second shaft connection fixing members.

[0007] A further preliminary embodiment of this utility model is as follows: the first connecting component is disposed between the upper fence and the middle fence, and the second connecting component is disposed between the middle fence and the lower fence.

[0008] A further preliminary embodiment of this utility model is as follows: the upper fence includes a top horizontal bar and two upper side vertical bars, with the upper side vertical bars arranged on both sides of the top horizontal bar; the middle fence includes two middle side vertical bars, with the upper and lower ends of the two middle side vertical bars converging to form a closed elongated frame; the lower fence includes a bottom horizontal bar and two lower side vertical bars, with the lower side vertical bars arranged on both sides of the bottom horizontal bar.

[0009] A further preliminary option of this utility model is as follows: the first front hook and the second front hook both include a base, a bent portion and a hook portion, the bent portion is disposed between the base and the hook portion, the end of the hook portion gradually approaches the base portion, the first front hook and the second front hook are both formed by bending a single metal piece; the first rear buckle and the second rear buckle are U-shaped.

[0010] A folding fence assembly is characterized by comprising a plurality of fence units, wherein a first and second shaft connection fastener of adjacent units are fixedly connected to each other, and folding is achieved between two connected fence units with the hook portion as the center.

[0011] A further preliminary embodiment of this utility model is as follows: the first front hook of the fence unit hooks the first rear buckle of the front fence unit, and the second front hook hooks the second rear buckle of the front fence unit; the first rear buckle is hooked by the first front hook of the rear fence unit, and the second rear buckle is hooked by the second front hook of the rear fence unit.

[0012] A further preliminary option of this utility model is: it also includes an auxiliary fence unit, which includes an auxiliary fence section, a third connecting component, and a fourth connecting component.

[0014] Compared with existing technologies, multiple individual fence units can be combined to form a fence assembly. The two ends of the fence assembly are connected to the doorway and the door, respectively, effectively solving the technical problem of pets rushing out of the house without permission. At the same time, the fence assembly can be folded with the connection between adjacent fence units as the center, which greatly reduces the storage volume. By setting a first connecting component including a first front hook and a first rear buckle at the upper part of the fence, and a second connecting component including a second front hook and a second rear buckle at the lower part, a "double connecting position + hook-buckle adaptation structure" is formed, which has significant technical advantages: On the one hand, this structure has strong adaptability. The first and second front hooks can flexibly hook onto external buckles or straight bars, and the first and second rear buckles can be hooked by external hooks. This supports stable connection between the fence unit and other fence components, and can also be adapted to fixed structures in common home scenarios such as doors and walls, effectively breaking the limitations of single connection scenarios. On the other hand, the symmetrical layout of the upper and lower double connecting components can evenly distribute the connection force at the upper and lower ends of the fence, avoiding loosening or detachment caused by excessive force at a single connection point, and greatly improving the overall connection stability. At the same time, the adaptation design of the hook and buckle can realize "hooking-buckle" between fence units. The "rotation" mechanism provides crucial structural support for the smooth folding operation after the assembly of multiple individual fence units, laying the foundation for convenient storage of fence components.

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0017] like Figures 1-7As shown, a fence unit 22 includes a fence section 1, a first connecting component, and a second connecting component. The first connecting component is located at the upper part of the fence section 1, and the second connecting component is located at the lower part of the fence section 1. Both the first and second connecting components include a first shaft-connecting fastener and a second shaft-connecting fastener. The first and second shaft-connecting fasteners of adjacent fence units are mutually adapted to achieve a shaft-connection and fixing effect. The first and second shaft-connecting fasteners are located on both sides of the fence section. The first shaft-connecting fastener has a hook structure, and the second shaft-connecting fastener has a buckle structure. The orientation of the first and second shaft-connecting fasteners can be interchanged.

[0018] like Figure 1 As shown, in Option 1, the hook structure is located on the front side, and the buckle structure is located on the rear side.

[0019] The first connecting component includes a first front hook 4 and a first rear buckle 5, and the second connecting component includes a second front hook 6 and a second rear buckle 7. The first front hook 4 and the second front hook 6 are used to hook onto external buckles or straight bars, and the first rear buckle 5 and the second rear buckle 7 are used to be hooked by external hooks. By setting the first connecting component with the first front hook 4 and the first rear buckle 5 at the upper part of the fence part 1, and setting the second connecting component with the second front hook 6 and the second rear buckle 7 at the lower part, a design of "double connecting positions at the top and bottom + hook-and-buckle adaptation structure" is formed, which has three core technical effects: First, it has strong adaptability. The first front hook 4 and the second front hook 6 can flexibly hook onto external buckles or straight bars, and the first rear buckle 5 and the second rear buckle 7 can be hooked by external hooks, which supports the connection between the fence unit and other fence components. It can also adapt to fixed structures in common home scenarios such as doors and walls, breaking the limitations of single connection scenarios; secondly, it has high connection stability. The symmetrical layout of the upper and lower double connection components 2 and 3 can evenly distribute the connection force at the upper and lower ends of the fence part 1, avoiding loosening or falling off due to excessive force on a single connection point; thirdly, it lays the foundation for the folding function. The matching structure of hooks 4 and 6 and buckles 5 and 7 can realize the "hooking-rotating" cooperation relationship between fence units, providing structural support for the folding operation after the assembly of multiple fence units.

[0020] like Figure 2 As shown, in Scheme 2: some hook structures are located on the front side, and some hook structures are located on the rear side; some buckle structures are located on the front side, and some buckle structures are located on the rear side. The first connecting assembly includes a first front hook 41 and a first rear buckle 42, and the second connecting assembly includes a second front buckle 43 and a second rear hook 44. The first front hook 41 and the second rear hook 44 are the first shaft-connecting fasteners, and the first rear buckle 42 and the second front buckle 43 are the second shaft-connecting fasteners.

[0021] The fence section 1 includes an upper fence 8, a middle fence 9, and a lower fence 10. The three-section design allows each area of ​​the fence section 1 to be designed independently according to functional requirements, while also facilitating segmented manufacturing and quality control during production and reducing the overall production difficulty.

[0022] The first connecting component is located between the upper fence 8 and the middle fence 9, and the second connecting component is located between the middle fence 9 and the lower fence 10. This optimizes the connection force and folding flexibility: On one hand, the connecting component is located at the junction of the two fence sections, directly serving as the connection node, allowing the connection force to act directly on the ends of the two fence sections, reducing the stress on the main body of fence section 1 and improving the overall structural stability; on the other hand, the corresponding layout of the connecting component and fence sections 8, 9, and 10 allows the folding rotation point to coincide with the fence section node, enabling the upper fence 8, middle fence 9, and lower fence 10 to rotate synchronously around the connecting components 2 and 3 during folding.

[0023] The upper fence 8 includes a top horizontal bar 11 and two upper side vertical bars 12, with the upper side vertical bars 12 positioned on either side of the top horizontal bar 11. The frame formed by the top horizontal bar 11 and the two side vertical bars 12 can effectively withstand external impacts from above, preventing deformation of the upper fence 8. Compared to a solid plate structure, the frame structure significantly reduces material usage while maintaining strength, lowering the overall weight of the fence unit and facilitating handling and installation.

[0024] The central fence 9 includes two central side vertical bars 13, whose upper and lower ends converge to form a closed, elongated frame. This closed frame structure creates a continuous protective surface, preventing pets from squeezing out through gaps in the central fence 9. Simultaneously, the hollow area within the elongated frame allows light to pass through, preventing the fence from being too enclosed and obstructing indoor lighting. This also reduces the overall weight of the fence unit, facilitating transport and installation.

[0025] The lower fence 10 includes a bottom horizontal bar 15 and two lower side vertical bars 16, which are located on both sides of the bottom horizontal bar 15. Compared with a solid plate structure, the frame structure significantly reduces the amount of material used while ensuring strength, reducing the overall weight of the fence unit and facilitating handling and installation.

[0026] Both the first front hook 4 and the second front hook 6 include a base 17, a bent portion 18, and a hook 19. The bent portion 18 is located between the base 17 and the hook 19. The end of the hook 19 gradually approaches the base 17. Both the first front hook 4 and the second front hook 6 are formed by bending a single piece of metal. The first rear buckle 5 and the second rear buckle 7 are U-shaped. The structure of "base 17 + bent portion 18 + hook 19" with the end of the hook 19 approaching the base 17 can form a "self-locking" hooking effect. After hooking an external buckle or straight rod, the close proximity between the end of the hook 19 and the base 17 can prevent the connection from accidentally falling off. At the same time, the "one-piece metal bending" process can ensure the overall strength of the hook and avoid the risk of breakage caused by welding or splicing. The U-shaped structure can form an open receiving space, which facilitates the quick insertion and positioning of external hooks.

[0027] The folding fence assembly includes multiple fence units 22 as described above. The first front hook 4 of the fence unit hooks the first rear buckle 5 of the front fence unit, and the second front hook 6 hooks the second rear buckle 7 of the front fence unit. The first rear buckle 5 is hooked by the first front hook 4 of the rear fence unit, and the second rear buckle 7 is hooked by the second front hook 6 of the rear fence unit. The two connected fence units are folded together with the hooked parts as the center. By assembling multiple individual fence units in a manner where "the front hook 4 hooks the front rear buckle 5, and the rear buckle 5 is hooked by the rear front hook 4," and using the hooked part as the rotation center, the core achieves three major technical effects: First, high assembly flexibility, allowing the number of fence units to be freely increased or decreased according to the required fence length or shape, adapting to spaces of different sizes; second, strong folding convenience, using the hooked part as the rotation center, multiple units can be folded synchronously without disassembly, the operation steps are simple, and a single person can complete the task; third, significantly reduced storage volume, after folding, each fence unit can be tightly stacked, compared to the traditional method of disassembling and scattering fixed fences, the overall volume after folding can be greatly reduced, greatly saving storage space, and making it convenient to store in small areas such as wardrobes and storage boxes.

[0028] It also includes auxiliary fence unit 23, which is usually located at the end of the fence assembly. Its function is to make both ends of the fence assembly hooks. Using only fence units would result in at least one end being a side-fastening part, making installation to the outside difficult. The auxiliary fence unit 23 includes an auxiliary fence section 24, a third connecting component, and a fourth connecting component. The third connecting component is located on the upper part of the auxiliary fence section 24, and the fourth connecting component is located on the lower part of the auxiliary fence section 24. Both the third and fourth connecting components include a front hook 27 and a rear hook 28. The front hook 27 is used to hook the first rear hook 5 and the second rear hook 7, and the rear hook 28 is used to hook the outside. This completely solves the problem that when using only conventional fence units, at least one end of the component is a side-fastening part, making it unsuitable for external installation requirements. It achieves a fence assembly structure with "hooks at both ends," significantly reducing the difficulty of end installation.

[0029] It also includes a movable hook portion 29, which is designed to fit into the doors 30 and door frames 31 on both sides. The doors 30 and door frames have insertion holes 32 for easy insertion and removal. The movable hook portion 29 includes a vertical rod 33 and at least one hook portion 34. The hook portion 34 includes a horizontal rod 35 and a vertical insertion rod 36. The vertical rod 33 is hooked by a first front hook portion 4 and a second front hook portion 6 and can move up and down. The vertical insertion rod 36 of the hook portion 34 precisely engages with the insertion holes 32 on the doors 30 and door frames 31, enabling rapid positioning and installation of the movable hook portion 29 with the door structure. Compared to traditional hooks that rely on bolts or adhesive for fixing, the insertion structure does not require damage to the door 30 or door frame 31, and the installation and removal process requires no tools. A single person can complete the operation within 30 seconds, significantly improving the efficiency of installation and removal in door-related scenarios.

[0030] The foregoing has provided a detailed description of a fence unit and a foldable fence assembly provided by this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are merely for the purpose of helping to understand this utility model and its core ideas. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
