Description

Technical Field

[0001] This utility model belongs to the field of municipal construction fence technology, specifically relating to a convenient water-filled fence. Background Technology

[0002] In scenarios such as municipal construction, large-scale event site isolation, and temporary area demarcation, fencing is widely used as an important safety protection and area separation tool. Traditional fencing mostly adopts a fixed structure, consisting of metal frames or precast concrete components. While it can meet basic isolation requirements, it has significant shortcomings in flexibility and portability. With the acceleration of urbanization and increasingly complex construction scenarios, higher demands are placed on the rapid deployment, flexible adjustment, and convenient storage of fencing. This has led to the development of various movable and assembleable temporary fencing systems. Among them, water-filled fencing, due to its stability achieved by increasing weight through water injection, has gradually become one of the mainstream choices.

[0003] Existing water-filled barriers are mostly designed as a single unit, with the frame and water-filled base fixedly connected. This makes it difficult to adjust the overall layout according to actual needs during assembly, limiting them to linear arrangements and making them unsuitable for complex construction areas such as curves and corners, thus restricting their applicability. While some movable water-filled barriers are equipped with casters, these casters are mostly fixed and cannot be folded, resulting in a slight risk of wobbling after deployment and insufficient stability. Removing the casters to improve stability would make moving the barriers difficult, especially in the absence of water, where moving multiple barriers manually would be extremely labor-intensive.

[0004] In view of this, we propose a convenient water-filled fence to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the technical problems of the existing fences in terms of flexibility, stability, portability and durability.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A portable water-filled barrier, comprising:

[0008] Multiple individual fence units, serving as the basic units of the fence, can be combined to form the basic framework of the fence.

[0009] Connecting components are used to connect adjacent fence units, enabling flexible assembly and angle adjustment, allowing the fence to adapt to layouts such as straight lines and curves;

[0010] The water-filled structure is assembled and installed on the fence unit. By filling the base of the water-filled structure with water, the weight is increased, which improves the stability of the fence. After draining, the weight is reduced, and it can be folded for easy movement and storage.

[0011] The bottom of each fence unit is equipped with two casters on both sides, which facilitate the movement of the fence and can be folded or unfolded. After the fence is set up, the casters can be folded to bring the base into contact with the ground, preventing the fence from moving at will.

[0012] This portable water-filled enclosure can be flexibly combined with multiple enclosure units and connecting components to adapt to various layouts such as straight lines and arcs, meeting the needs of different scenarios. The water-filled structure increases stability by adding weight when filled with water and reduces weight by draining water, making it easy to move and store. It is equipped with foldable casters, which not only facilitates movement but also ensures that the base is grounded and prevents movement after deployment by folding the casters. Overall, it achieves multiple benefits such as flexible assembly, stable use, convenient movement and storage.

[0013] Preferably, the fence unit includes a main frame consisting of two horizontal support rods (top and bottom), two vertical support rods (left and right), and four corner tubes. Each corner tube is inserted into the horizontal and vertical support rods at both ends and fits onto the outer side of the horizontal and vertical support rods. An integrally formed reinforcing rib is fixedly provided on the corner tube.

[0014] The connecting rods are fixedly connected to the bottom of the two corner tubes of the fence unit. The two casters are fixed to the bottom of the connecting rods respectively. The structural design of the fence unit enhances the stability of the frame through plug-in assembly, and the reinforcing ribs improve the resistance to deformation. The connecting rods provide a stable installation base for the casters.

[0015] Preferably, the caster wheel includes a U-shaped plate A fixed to the bottom of the connecting rod and inclined on both sides, a U-shaped plate B rotatably connected to the U-shaped plate A via an axle and inclined on both sides, and a caster wheel with brake fixed to the bottom of the U-shaped plate B;

[0016] U-shaped plate A and U-shaped plate B are connected by two tension springs installed at the front and back;

[0017] When the casters are in the extended position, the U-shaped plate B rotates and wraps around the outer side of the U-shaped plate A and is located below the U-shaped plate A, and the tension spring is in the retracted state.

[0018] When the casters are folded, U-shaped plate B rotates and connects to the outside of U-shaped plate A. The tension spring is in a stretched state and is limited above the two limiting blocks on the front and rear sides of U-shaped plate B. The design of the casters enables flexible folding and unfolding. The tension spring and limiting blocks ensure stability in both states. The brake function further improves the convenience and safety of use.

[0019] Preferably, the connecting component includes two C-shaped clips that snap into two adjacent corner tubes, a connecting shaft and a locking element that are fixed to the two C-shaped clips respectively. The connecting component enables the adjacent corner tubes to be quickly engaged by the C-shaped clips, realizing convenient connection between individual fence units and laying the foundation for flexible assembly.

[0020] As a preferred embodiment, the connecting shafts of the two C-type cards are integrally formed with lugs A and B that are mutually inserted and have holes, and the locking element is a screw that is screwed into the holes on lugs A and B.

[0021] The connecting components enable rotational connections between individual fence units, allowing the fence to be adjusted in shape as needed. The tightening screw is used to lock the connecting shaft after the fence unit is adjusted to the appropriate angle, maintaining the stability of the fence shape. This connecting component design enables rotational adjustments between fence units, and the tightening screw can lock the angle, ensuring the stability of the fence shape and the flexibility of the layout.

[0022] As a preferred embodiment, the water injection structure also includes a fence panel that is assembled and installed on the main frame. The fence panel has four sleeves integrally formed on its upper, lower, left, and right sides, which are inserted into the upper and lower horizontal support rods and the left and right vertical support rods and are fitted on the outer sides of the upper and lower horizontal support rods and the left and right vertical support rods. The base is fixed to the bottom of the front and rear sides of the fence panel and is located below the bottom sleeve.

[0023] The fence panel has several vertically spaced and horizontally arranged perforated holes. The water-filled fence panel is firmly connected to the main frame through a sleeve. The perforated holes reduce weight and wind resistance, while the base enhances overall stability.

[0024] Preferably, the base has a water inlet located above the center of its rear side and two drain outlets on both sides below. Both the water inlet and drain outlets are equipped with sealing caps. Water is injected into the water inlet of the base through the water inlet to increase the weight of the fence. When it needs to be moved or stored, the water can be drained through the drain outlets to reduce the weight. The design of the water inlet and drain outlet of the base, together with the sealing caps, allows for flexible adjustment of the weight, taking into account both the stability of the fence during use and the convenience of moving and storing it.

[0025] As a preferred option, the sleeve is positioned between the two corner inserts, effectively preventing the fence panel from shifting and ensuring the stability of the connection between the water injection structure and the main frame.

[0026] As a preferred option, the main frame is made of plastic or metal, while the water injection structure is made of plastic. The choice of materials for the main frame and the water injection structure takes into account strength, weight and corrosion resistance, adapts to different usage scenarios, and extends the service life of the fence.

[0027] Compared with the prior art, the technical effects and advantages of this utility model are:

[0028] This invention effectively solves the problem of limited layout adjustment in existing fences by using modular fence units and flexible connecting components. Adjacent fence units can rotate at multiple angles through the connecting components, allowing for both straight layouts and adaptation to complex scenarios such as curves and corners. After angle adjustment, the fence can be quickly locked by tightening screws without disassembly and reassembly, significantly improving the fence's adaptability to diverse construction environments and installation and adjustment efficiency.

[0029] The combination of the water-filling structure and the retractable casters achieves a balance between stability and portability. When filled with water, the increased weight of the base enhances the overall stability of the fence, preventing swaying or tipping; after draining, the reduced weight, combined with the unfolded casters, allows for easy pushing and moving, resolving the contradiction of traditional fences being "stable but difficult to move, easy to move but unstable." Furthermore, with the casters folded, the base directly contacts the ground, further ensuring stability after deployment and balancing ease of movement with safety.

[0030] The fence's frame and water-filling structure are assembled using a plug-in method. Each component is precisely fitted together via corner inserts and sleeves, ensuring connection strength while simplifying the assembly process. The material selection for the main frame and water-filling structure (plastic or metal frame paired with a plastic water-filling structure) balances lightweight design with durability, reducing connection loosening issues caused by material incompatibility. The reinforcing ribs further enhance the frame's resistance to deformation, extending its overall service life.

[0031] The perforated design of the fence panels and the foldable nature of each component further optimize the user experience. The perforations reduce the impact of wind resistance on the fence while maintaining unobstructed visibility; the overall structure is significantly reduced in size after drainage and folding, facilitating centralized storage and transportation, and reducing storage space occupation. Compared with existing technologies, this invention has significantly improved in terms of functional completeness, ease of operation, and scene adaptability, and is better able to meet the actual needs of temporary isolation scenarios.

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] The following combination Figures 1 to 8 This application will be described in further detail.

[0047] This application discloses a convenient water-filled fence, including multiple fence units 1, connecting components 2, and a water-filling structure 3. The multiple fence units 1 serve as the basic units of the fence, and can be combined to form the basic frame of the fence. The connecting components 2 are used to connect adjacent fence units 1, enabling flexible assembly and angle adjustment, allowing the fence to adapt to straight lines, arcs, and other layouts. The water-filling structure 3 is assembled and installed on the fence units 1. By filling the base 31 of the water-filling structure 3 with water, the weight is increased, improving the stability of the fence. After draining, the weight is reduced, and it is easy to move and store after folding. The bottom sides of the fence units 1 are provided with two universal wheels 4 that facilitate the movement of the fence and can be folded or unfolded. After the fence is set up, the universal wheels 4 can be folded to make the base 31 contact the ground, preventing the fence from moving at will.

[0048] The main frame structure of fence unit 1 is composed of two horizontal support rods 11 (top and bottom), two vertical support rods 12 (left and right), and four corner inserts 13. The main frame is made of plastic or metal. Plastic is lightweight, corrosion-resistant, and low-cost, making it suitable for short-term municipal construction. Metal is stronger and more impact-resistant, making it suitable for scenarios with high traffic volume and long construction periods.

[0049] Each corner tube 13 is inserted into the horizontal support rod 11 and the vertical support rod 12 at both ends, and is fitted onto their outer sides. This insertion method makes the frame assembly convenient and the connection firm, which is convenient for disassembly and replacement of parts later.

[0050] An integrally formed reinforcing rib 14 is fixed on the corner insertion tube 13. The reinforcing rib 14 can effectively enhance the structural strength at the corner, reduce deformation caused by external impact, and extend the service life of the fence.

[0051] Connecting rods 15 are fixedly connected to the bottom of the two corner inserts 13 at the bottom of the fence unit 1, and two casters 4 are fixed to the bottom of the connecting rods 15 respectively. The connecting rods 15 serve to connect and bear the load, and evenly transmit the force of the casters 4 to the corner inserts 13, ensuring the stability of the casters 4 during use.

[0052] The connecting assembly 2 includes two C-shaped clips 21 that respectively snap into two adjacent corner insertion tubes 13, a connecting shaft 22 fixed to the two C-shaped clips 21, and a locking member 23. The C-shaped clips 21 are made of metal or high-strength plastic with a certain degree of elasticity, which can be tightly locked onto the corner insertion tubes 13 and are not easy to fall off.

[0053] The connecting shafts 22 of the two C-type clips 21 are integrally formed with interlocking lugs A24 and B25, each with a hole. The locking element 23 is a screw-type screw that screws into the holes on lugs A24 and B25. By rotating lugs A24 and B25 relative to each other, the angle between adjacent fence units 1 can be adjusted, allowing the fence to adapt to different layouts such as straight lines and curves according to the needs of municipal construction. When the appropriate angle is reached, the screw-type screw is screwed into the hole to lock the connecting shaft 22, maintaining the stability of the fence shape and preventing changes in angle due to external forces during construction.

[0054] The connecting component 2 enables flexible connection and angle adjustment between individual fence units 1, making the fence assembly more flexible and diverse, adaptable to construction areas of different shapes and sizes, and improving the applicability and practicality of the fence.

[0055] The water-filling structure 3 includes a base 31 and a fence panel 32. The fence panel 32, made of lightweight and resilient plastic, is assembled onto the main frame and is lightweight and fitted onto the main frame. Each of the four sides of the fence panel 32 has four integrally formed sleeves 33 that fit into the upper and lower horizontal support rods 11 and the left and right vertical support rods 12, respectively. These sleeves 33 are positioned between two corner inserts 13. This design ensures the strong connection between the fence panel 32 and the main frame, and also positions the fence panel 32 to prevent displacement during use. The fence panel 32 has several vertically spaced and horizontally arranged perforated holes 34. These holes not only reduce the weight of the fence panel 32, facilitating handling and installation, but also ensure unobstructed visibility inside and outside the fence, allowing construction personnel to observe the external situation. They also reduce wind resistance and improve the stability of the fence in windy weather.

[0056] The base 31 is fixed to the bottom of the front and rear sides of the fence panel 32 and located below the bottom sleeve 33. It is made of plastic and has good sealing and corrosion resistance. The base 31 has a water inlet 35 located above the center of its rear side and two drain outlets 36 on the lower sides. Both the water inlet 35 and drain outlets 36 are equipped with sealing caps made of rubber, ensuring good sealing performance and preventing leakage. Injecting water into the water inlet 35 increases the weight of the fence, improving its stability during construction and preventing it from being blown over or displaced by collisions. When the fence needs to be moved or stored, draining water through the drain outlets 36 reduces its weight, facilitating handling and folding for storage, thus saving storage space.

[0057] Water-filling structure 3 adjusts the weight of the fence by filling and draining water, achieving a balance between fence stability and portability. Filling with water during construction increases weight and ensures fence stability; draining water during movement and storage reduces weight, improving the fence's ease of use.

[0058] The caster wheel 4 includes a U-shaped plate A41 fixed to the bottom of the connecting rod 15 and inclined on both sides, a U-shaped plate B43 rotatably connected to the U-shaped plate A41 via a shaft 42 and inclined on both sides, and a braked caster wheel 44 fixed to the bottom of the U-shaped plate B43; the U-shaped plate A41 and the U-shaped plate B43 are connected by two tension springs 45 arranged at the front and rear. The U-shaped plate A41 and the U-shaped plate B43 are made of metal, with high strength, and can withstand the weight of the fence; the tension springs 45 are made of high-strength spring steel, with good elasticity and toughness, ensuring smooth switching of the caster wheel 4 during folding and unfolding.

[0059] Folded and unfolded states:

[0060] When the caster wheel 4 is in the unfolded state, the U-shaped plate B43 rotates and wraps around the outer side of the U-shaped plate A41 and is located below the U-shaped plate A41. The tension spring 45 is in the retracted state. At this time, the caster wheel 44 with brake contacts the ground, which facilitates the movement of the fence. The brake function can lock the caster wheel 4 after the fence is moved to the designated position to prevent it from rolling randomly.

[0061] When the caster wheel 4 is in the folded state, the U-shaped plate B43 rotates and connects to the outside of the U-shaped plate A41. The tension spring 45 is in the stretched state and is limited above the two limiting blocks 46 on the front and rear sides of the U-shaped plate B43. At this time, the base 31 contacts the ground to prevent the fence from moving at will and to ensure the stability of the fence during construction.

[0062] When converting the swivel caster 4 from its folded state to its unfolded state, pull the tension spring 45 below the limit block 46, lift the railing, and kick the U-shaped plate B43 with your foot. This will rotate the U-shaped plate B43 to below the U-shaped plate A41 via the shaft 42, and keep it in the unfolded state under the action of the tension spring 45.

[0063] The foldable or unfoldable casters 4 facilitate the movement and fixation of the fence. When the fence needs to be moved, unfold the casters 4 and easily push the fence to the designated position; after the fence is in place, fold the casters 4 so that the base 31 contacts the ground, ensuring the stability of the fence and preventing it from moving during construction, thus improving the convenience and reliability of the fence.

[0064] This portable water-filled fence, through its rational structural design, flexibly combines multiple fence units 1 via connecting components 2, along with a water-filling structure 3 and foldable casters 4, achieving multiple advantages in municipal construction. Its material selection balances strength, weight, and cost, and the coordinated operation of each structural component ensures the fence's stability during construction while improving its ease of movement, storage, and assembly, effectively meeting the needs of temporary fencing in municipal construction.

[0065] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
