Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and specifically relates to a building construction fence with internal support, quick locking, collaborative storage and internal self-cleaning functions, and its installation method. Background Technology

[0002] Fences are crucial safety protection facilities during construction. Chain-link fences, due to their foldability, ease of transport, and flexible deployment, are widely used in temporary construction scenarios. However, existing chain-link fences suffer from the following technical problems in practical use: First, when unfolded, they rely solely on hinge points for connection, lacking effective internal rigid support, resulting in poor overall stability and susceptibility to tipping over under external forces. Second, the locking mechanisms between fence panels are often independent components, inconvenient to operate, and cannot be stored with the main fence structure, easily leading to loss or occupying additional space. Third, fences are often installed at an angle, making their inner surface (the side facing the construction area) difficult to be directly washed away by rainwater, easily accumulating dust and mud, requiring frequent manual cleaning, and increasing maintenance costs. Currently, there is no integrated fence solution that simultaneously solves the aforementioned problems of stability, ease of operation, storage, and self-cleaning. Summary of the Invention

[0003] The technical problems to be solved by this invention are: how to improve the overall stability of the chain-link fence after it is deployed and prevent it from tipping over; how to achieve rapid locking and unlocking between the fence panels and make the locking structure reasonably folded up with the fence; and how to achieve automatic washing of the inner surface of the fence panels when the fence is installed at an angle, reducing the labor intensity of manual cleaning, and making the related structure compact and functionally integrated. Therefore, this invention aims to solve the technical problems of insufficient internal support, inconvenient locking operation, poor storage, and difficulty in self-cleaning the inner surface of existing chain-link fences, and to provide a construction fence with internal support and self-cleaning functions and its installation method.

The hinge shaft (4) is fixed to the inner surface of the first panel unit (8), and the swing seat (5) is rotatably connected to the hinge shaft (4). The sleeve assembly (6) is composed of an outer tube (9) and an inner tube (10) sleeved inside it.

[0005] Preferably, a gap is left between each two adjacent panel units (8), and the gap width is 5-10mm.

[0006] As a preferred embodiment, each of the panel units (8) has a plurality of countersunk holes (15) on its inner side along its width direction, and a self-made spring seat (7) is embedded and fixed in each of the countersunk holes (15), and the elastic end of the self-made spring seat (7) is compressed and stored in the countersunk hole (15).

[0007] Preferably, the self-made spring seat (7) includes a fixed seat (16), a telescopic rod (17), a locking seat (18), and a spring (19). The fixed seat (16) has a stepped cavity (20) inside. A through hole (21) communicating with the stepped cavity (20) is opened from one end of the fixed seat (16). The inner end of the telescopic rod (17) is inserted into the stepped cavity (20) through the through hole (21) and fixed with a limiting plate (22). The outer end of the telescopic rod (17) is connected to the locking seat (18). The spring (19) is sleeved on the periphery of the telescopic rod (17), and the two ends of the spring (19) elastically abut against the opposing surfaces between the fixed seat (16) and the locking seat (18). The locking seat (18) is made of rubber.

[0008] Preferably, the hinge shaft (4) is mounted on the inner surface of the panel unit (8) near the end of the panel unit (8) it is located.

[0009] As a preferred embodiment, a rotating groove (23) is provided on the inner surface of at least the two end panels (8), and a support plate (24) is hinged in the rotating groove (23).

[0010] Preferably, the outer layers of the first flexible permeable sleeve (13) and the second flexible permeable sleeve (14) are provided with a fleece layer (25). The fleece layer (25) is fixed on the outer surface of the first flexible permeable sleeve (13) and the second flexible permeable sleeve (14) with rubber as the base material. The fleece layer (25) is attached to the inner surface of the panel unit (8). The first lock hole (11) and the second lock hole (12) respectively penetrate the fleece layer (25).

[0011] Preferably, the locking seat (18) at the outer end of the self-made spring seat (7) is provided with a variable diameter part (26). The variable diameter part (26) is tapered and gradually thickens towards the outer end. When the first locking hole (11) and the second locking hole (12) are engaged with the self-made spring seat (7), the locking seat (18) is inserted into the first locking hole (11) and the second locking hole (12), and the outer end of the variable diameter part (26) abuts against the cavity wall of the outer tube (9) or the inner tube (10) to form a self-locking mechanism.

[0012] Preferably, a rotation control component (27) is installed at the free end of the swing base (5). The rotation control component (27) includes a first connecting base (28), a second connecting base (29), and a third connecting base (30). An arc-shaped groove (31) is formed in the radial position of the first connecting base (28). The second connecting base (29) is connected to the first connecting base (28), so that the arc-shaped groove (31) is fixed between the two connecting bases. A connecting hole is formed from the non-connecting end of the second connecting base (29) into the first connecting base (28). The arc-shaped groove (31) is located in the radial position of the connecting hole. The third connecting seat (30) is connected to the connecting hole. The non-connecting end of the second connecting seat (29) is inserted into the connecting hole. A limiting rotation rod (32) is fixed on the outer wall of the insertion end of the third connecting seat (30).

A flange connecting plate (33) is fixed to the non-insertion end of the third connecting seat (30). The flange connecting plate (33) is fixedly connected to one end of the outer tube (9) near the hinge shaft (4).

[0013] Another technical solution of the present invention is the installation method of the construction fence, applicable to the construction fence of any of the foregoing claims, characterized in that it includes the following installation steps: Step 1: Clean up debris and mark the installation baseline according to the construction area. Unroll the retracted fence assembly (1), open the support plate (24), and place the fence assembly (1) on the periphery of the building construction. Step 2: Push the swing seat (5) to rotate it around the hinge axis (4). The swing seat (5) drives the sleeve assembly (6) to rotate, so that the sleeve assembly (6) rotates to the horizontal along the inner surface of the panel unit (8). Step 3: Stretch the inner tube (10) so that the inner tube (10) moves outward along the outer tube (9) to increase the length of the sleeve assembly (6) so that the length of the sleeve assembly (6) matches the fence assembly (1). Step 4: Rotate and adjust the angle of the outer tube (9) so that the first locking hole (11) on the outer tube (9) corresponds to the position of the self-made spring seat (7) on the inner surface of part of the railing unit (8) and insert them one by one; rotate and adjust the angle of the inner tube (10) so that the second locking hole (12) on the inner tube (10) corresponds to the position of the self-made spring seat (7) on the inner surface of another part of the railing unit (8) and insert them one by one, and at the same time attach the fleece layer (25) on the first flexible seepage sleeve (13) and the second flexible seepage sleeve (14) to the inner surface of the railing unit (8) to complete the installation.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The internal support structure of the fence assembly is formed by the insertion relationship between the sleeve assembly and the self-made spring seat, which tightly connects each fence panel unit, distributes the force, significantly improves the stability between the fence panel units, and prevents the fence from tipping over; at the same time, the spring seat and the lock hole are connected to achieve quick locking and unlocking, which is simple and efficient to operate.

[0015] (2) The sleeve assembly can be stored synchronously with the fence: Press the elastic end of the self-made spring seat to make it disengage from the lock hole, and the lock can be quickly released; then push the inner tube to retract into the outer tube to complete the sleeve assembly shrinkage, and then rotate the shrunken sleeve assembly back to its original position with the swing seat around the hinge axis, and fit it against the inner surface of the first fence unit. Finally, fold the chain fence unit to achieve synchronous storage of the locking structure and the fence body without taking up extra space.

[0016] (3) A first flexible permeable sleeve is installed on the outer pipe, and a second flexible permeable sleeve is installed on the inner pipe. Utilizing their own permeability, rainwater is collected and guided to the inner surface of the parapet unit, guiding the rainwater to form a continuous water film from top to bottom along the inner surface. Under the combined effect of continuous water flow and the downward pull of gravity of the water film, dust, mud, and other debris attached to the inner surface are carried away, achieving self-cleaning of the inner surface. Through the uniform permeation effect of the flexible permeable sleeves, compared with the random and intermittent permeation of existing technologies that rely on gaps, a larger area and more stable water flow coverage can be formed on the inner surface of the parapet, significantly improving the self-cleaning effect.

[0017] Meanwhile, the outside of the parapet unit can naturally receive rainwater, eliminating the need for manual cleaning and significantly reducing labor intensity; the water spray structure is integrated into the sleeve assembly, and based on the swing and contraction performance of the sleeve assembly, the two functional structures are compact, reasonable, and highly functional.

[0018] (4) The gaps between the panel units can prevent friction and jamming when the hinges rotate, and at the same time help rainwater seep into the inner surface, improving the flushing effect.

[0019] (5) A self-made spring seat is embedded and fixed in the countersunk hole. When stored, it can be completely compressed into the countersunk hole to avoid interference with adjacent parts, protect the spring seat, and reduce storage space.

[0020] (6) The plush layer enhances the fit between the flexible permeable sleeve and the inner surface of the parapet unit, improving rainwater collection and diversion effects and reducing rainwater splashing.

[0021] (7) The variable diameter design enables the locking seat to self-lock after being inserted into the lock hole, preventing loosening and falling off, and improving locking reliability.

[0022] (8) The rotation angle control component limits the rotation angle of the sleeve assembly, which makes it easy for operators to accurately adjust the position of the sleeve assembly. It can also be used to manually clean the inner surface of the guardrail unit by utilizing its limited rotation range, thus expanding its functionality.

[0023] (9) The installation method is simple and easy to operate, and can quickly realize the deployment, locking and water spraying structure of the fence. Attached Figure Description

[0025] Explanation of key component symbols: Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings: Example 1

[0027] like Figures 1-9 As shown, this embodiment provides a construction fence, including a fence assembly 1, a locking mechanism 2, and a water-spraying structure 3.

[0028] The fence assembly 1 consists of several fence panel units 8 hinged together in a chain arrangement, with a gap of 5-10mm between each pair of adjacent fence panel units 8. This gap prevents friction and jamming when the fence panel units 8 are hinged and rotated, and also helps rainwater seep into the inner surface, improving the rinsing effect.

[0029] The locking mechanism 2 includes a hinge shaft 4, a swing base 5, a sleeve assembly 6, and a self-made spring seat 7. The hinge shaft 4 is fixed to the inner surface of the first panel unit 8, and the swing base 5 is rotatably connected to the hinge shaft 4. The sleeve assembly 6 consists of an outer tube 9 and an inner tube 10 sleeved inside it. One end of the outer tube 9 is rotatably connected to the free end of the swing base 5, and the inner tube 10 can slide along the axial direction of the outer tube 9. The outer tube 9 and the inner tube 10 are respectively provided with a number of first locking holes 11 and second locking holes 12 along their length direction.

[0030] A self-made spring seat 7 is fixed to the inner surface of each balustrade unit 8 and arranged along the chain-like direction, with its elastic end extending out of the inner surface of the balustrade unit 8. Specifically, each balustrade unit 8 has several countersunk holes 15 along its width direction on its inner side, and a self-made spring seat 7 is embedded and fixed in each countersunk hole 15. The elastic end of the self-made spring seat 7 is compressed and stored in the countersunk hole 15. Figure 6 , Figure 7 As shown, the self-made spring seat 7 includes a fixed seat 16, a telescopic rod 17, a locking seat 18, and a spring 19. The fixed seat 16 has a stepped cavity 20, and a through hole 21 communicating with the stepped cavity 20 is opened from one end of the fixed seat 16 inward. The inner end of the telescopic rod 17 is inserted into the stepped cavity 20 through the through hole 21 and fixed with a limit plate 22. The outer end of the telescopic rod 17 is connected to the locking seat 18. The spring 19 is sleeved on the periphery of the telescopic rod 17, and the two ends of the spring 19 elastically abut against the opposing surfaces between the fixed seat 16 and the locking seat 18. The locking seat 18 is made of rubber.

[0031] Some of the self-made spring seats 7 correspond to the first locking hole 11, and the rest correspond to the second locking hole 12. When the outer tube 9 and the inner tube 10 are rotated to a horizontal position, the first locking hole 11 and the second locking hole 12 can be engaged with the corresponding self-made spring seats 7 one by one. The locking seat 18 at the outer end of the self-made spring seat 7 is provided with a variable diameter part 26. The variable diameter part 26 is tapered and gradually thickens towards the outward end. When the first locking hole 11 and the second locking hole 12 are engaged with the self-made spring seat 7, the locking seat 18 is inserted into the first locking hole 11 and the second locking hole 12, and the outer end of the variable diameter part 26 presses against the tube wall of the outer tube 9 or the inner tube 10 to form a self-locking mechanism to prevent loosening.

[0032] The water-spraying structure 3 includes a first flexible permeable sleeve 13 and a second flexible permeable sleeve 14. The first flexible permeable sleeve 13 is connected to the wall of the outer tube 9 and extends along its length. When the outer tube 9 is rotated to a horizontal position, the first flexible permeable sleeve 13 adheres to the inner surface of a portion of the parapet unit 8, aligning the directional discharge hole with the inner surface of that portion of the parapet unit 8. The second flexible permeable sleeve 14 is fixed to the wall of the inner tube 10 and extends along its length. When the inner tube 10 is rotated to a horizontal position, the second flexible permeable sleeve 14 adheres to the inner surface of the remaining parapet units 8. The outer layers of both the first flexible permeable sleeve 13 and the second flexible permeable sleeve 14 are provided with a fleece layer 25. The fleece layer 25 is fixed to the outer surface of the first flexible permeable sleeve 13 and the second flexible permeable sleeve 14 with rubber as the base material. The fleece layer 25 adheres to the inner surface of the parapet unit 8, and the first locking hole 11 and the second locking hole 12 respectively penetrate the fleece layer 25. The pile layer 25 enhances adhesion, improves rainwater collection and diversion, and reduces rainwater splashing.

[0033] The hinge shaft 4 is mounted on the inner surface of the fence unit 8 near one end of the hinge shaft 4. At least the two outermost fence units 8 have rotation grooves 23 on their inner surfaces, and support plates 24 are hinged within the rotation grooves 23. The support plates 24 can be rotated to a supported state, contacting the ground to form end auxiliary support, further improving the stability of the fence.

[0034] An angle control component 27 is installed at the free end of the base 5. For example... Figure 2 , Figure 8 As shown, the corner control assembly 27 includes a first connecting seat 28, a second connecting seat 29, and a third connecting seat 30. An arc-shaped groove 31 is formed radially on the first connecting seat 28. The second connecting seat 29 is connected to the first connecting seat 28, fixing the arc-shaped groove 31 between the two connecting seats. A connecting hole is formed from the non-connecting end of the second connecting seat 29 into the first connecting seat 28. The arc-shaped groove 31 is located radially within the connecting hole and communicates with it. The third connecting seat 30 is inserted into the connecting hole from the non-connecting end of the second connecting seat 29. A limiting rotation rod 32 is fixed to the outer wall of the inserted end of the third connecting seat 30. The limiting rotation rod 32 is inserted radially into the arc-shaped groove 31 to restrict the third connecting seat 30 to rotate only within the arc length of the arc-shaped groove 31. A flange connecting plate 33 is fixed to the non-insertion end of the third connecting seat 30, and the flange connecting plate 33 is fixedly connected to the end of the outer tube 9 near the hinge shaft 4. The rotation control component 27 can limit the rotation angle of the sleeve assembly 6 within a preset range (e.g., 0°-90°), which is convenient for operators to make precise adjustments. At the same time, its limited rotation range can be used to manually clean the inner surface of the guardrail unit 8.

[0035] The working principle of this embodiment is as follows: When the fence is unfolded, the fence assembly 1, which is in a retracted state, is unfolded, and the support plate 24 is opened to support it on the ground. The swing seat 5 is pushed to rotate around the hinge axis 4, causing the sleeve assembly 6 to rotate to a horizontal position. The inner tube 10 is stretched so that the length of the sleeve assembly 6 matches that of the fence assembly 1. The angles of the outer tube 9 and the inner tube 10 are adjusted by rotation so that the first locking hole 11 and the second locking hole 12 are respectively inserted into the self-made spring seat 7 on the corresponding fence unit 8. After the locking seat 18 is inserted into the locking hole, it self-locks through the reducing part 26, completing the internal support and locking. At the same time, the first flexible water-permeable sleeve 13 and the second flexible water-permeable sleeve 14 are attached to the inner surface of the fence unit 8. In rainy weather, rainwater is collected by the flexible water-permeable sleeves and guided to the inner surface, flowing along the inner surface to wash away debris, achieving self-cleaning.

[0036] When storing the fence, press the locking seat 18 of the self-made spring seat 7 to disengage it from the lock hole, push the inner tube 10 back into the outer tube 9, then rotate the sleeve assembly 6 back to fit the inner surface of the first fence panel unit 8 with the swing seat 5, and finally fold the fence panel unit 8 to complete the storage. Example 2

[0037] This embodiment provides an installation method for a construction fence, applicable to the construction fence described in Embodiment 1, including the following steps: Step 1. Clear away debris and mark the installation baseline according to the construction area. Unroll the retracted fence assembly 1, open the support plate 24, and place the fence assembly 1 around the perimeter of the construction site. Step 2. Push the swing seat 5 to rotate it around the hinge axis 4. The swing seat 5 drives the sleeve assembly 6 to rotate, so that the sleeve assembly 6 rotates to the horizontal along the inner surface of the parapet unit 8. Step 3. Stretch the inner tube 10 so that the inner tube 10 moves outward along the outer tube 9 to increase the length of the sleeve assembly 6 so that the length of the sleeve assembly 6 matches the fence assembly 1. Step 4. Rotate and adjust the angle of the outer tube 9 so that the first locking hole 11 on the outer tube 9 corresponds to the position of the self-made spring seat 7 on the inner surface of part of the railing unit 8 and insert them one by one; rotate and adjust the angle of the inner tube 10 so that the second locking hole 12 on the inner tube 10 corresponds to the position of the self-made spring seat 7 on the inner surface of another part of the railing unit 8 and insert them one by one, and at the same time attach the fleece layer 25 on the first flexible seepage sleeve 13 and the second flexible seepage sleeve 14 to the inner surface of the railing unit 8, and the installation is completed.

[0038] The three-part argument of the technical problem, technical means, and technical effect of this invention 1. Regarding the technical problem of "existing chain-link fences lacking internal support structures and having poor stability": Technical means: A locking mechanism is adopted, which includes a hinge shaft, a swing seat, a sleeve assembly, and a self-made spring seat. The hinge shaft is fixed to the inner surface of the first panel unit, and the swing seat is rotatably connected to the hinge shaft; the sleeve assembly consists of an outer tube and an inner tube sleeved together, with one end of the outer tube rotatably connected to the free end of the swing seat; the self-made spring seat is fixed to the inner surface of each panel unit with its elastic end protruding; when the outer tube and the inner tube rotate to a horizontal position, the first locking hole and the second locking hole on them can engage with the corresponding self-made spring seat one by one.

[0039] Technical effect: By connecting the sleeve assembly with multiple self-made spring seats distributed along the chain arrangement direction, a rigid support frame that runs through multiple fence panels is constructed inside the fence, tightly connecting each fence panel unit into a whole, effectively dispersing external forces, and significantly improving the overall structural stability and anti-tipping ability of the fence.

[0040] 2. Regarding the technical issues of "inconvenient operation of the locking mechanism and inability to coordinate with the fence for storage": Technical means: The sleeve assembly adopts an inner and outer layer sleeve structure and can rotate around the hinge axis. When locking, rotate the swing seat to make the sleeve assembly horizontal, stretch the inner tube to the appropriate length, and lock it with the self-made spring seat through the lock hole; when storing, press the self-made spring seat to make its elastic end disengage from the lock hole, the inner tube retracts into the outer tube, and then rotate the sleeve assembly around the hinge axis to reset and fit against the inner surface of the panel unit.

[0041] Technical benefits: The locking mechanism and the fence body are integrated into a single design. Locking is achieved through simple rotation, stretching, and snapping, requiring no additional tools and offering high efficiency and convenience. When stored, the locking mechanism folds compactly with the fence, saving space and avoiding the problems of easily lost or difficult-to-manage independent locking components.

[0042] 3. Regarding the technical issue that "the inner surface of the fence cannot be self-cleaned by rainwater when it is installed at an angle": Technical means: A first flexible seepage sleeve and a second flexible seepage sleeve are respectively installed on the outer and inner pipes. When the pipe assembly is horizontally locked, these two flexible seepage sleeves are tightly attached to the inner surface of the corresponding parapet unit.

[0043] Technical benefits: The flexible permeable sleeve utilizes its own permeability to collect rainwater or water used for manual washing and guide it to the inner surface of the parapet unit. This allows the water to flow evenly from top to bottom along the inner surface, washing away adhering dust and mud, achieving a self-cleaning function and significantly reducing manual cleaning and maintenance costs. Simultaneously, this functional structure is cleverly integrated into the sleeve assembly, which serves as a supporting component, achieving "multi-purpose functionality" with a compact structure and strong functionality.

[0044] Demonstration of synergistic effects and systemic effects among features: The technical solution of this invention is not a simple superposition of multiple independent functions; rather, there is a close synergistic effect among its constituent features, which together produce a systemic effect that transcends individual functions. The locking mechanism and the water-spraying structure work in synergy: The water-spraying structure (first and second flexible permeable sleeves) is directly attached to the core components of the locking mechanism (outer and inner tubes). While providing internal support and locking the fence units, the locking mechanism also provides an installation carrier and positioning reference for the water-spraying structure. When the locking mechanism is rotated and stretched to its working position, the water-spraying structure precisely adheres to the inner surface of each fence unit, requiring no additional installation or adjustment steps. This "support-as-positioning" synergistic design allows the fence's self-cleaning function to automatically deploy the moment it achieves stable locking, greatly simplifying the operation process.

[0045] The multifunctionality of the homemade spring seat: The homemade spring seat is not only a key locking component in the locking mechanism, but its elastic and telescopic characteristics also enable multiple functions. When locked, its elastic end extends and engages with the lock hole, providing a reliable connection; when stored, it can be compressed and completely sunk into the countersunk hole, avoiding interference with adjacent components and ensuring the compactness of the fold; the rubber material and variable diameter design of its end locking seat can form an elastic self-locking mechanism with the inner wall of the cavity after being inserted into the lock hole, further enhancing the stability of the connection and providing a certain degree of shock absorption and cushioning, protecting the structure from impact damage.

[0046] Synergistic Adjustability and Functional Coverage of the Sleeve Assembly: The inner and outer interlocking structure of the sleeve assembly allows for length adjustment, flexibly adapting to fence assemblies of different lengths. This feature ensures that the locking mechanism provides continuous internal support regardless of the fence's extended length. Simultaneously, the first and second flexible permeable sleeves attached to it completely cover the inner surfaces of all fence panels, achieving full spatial coverage of support and cleaning functions and avoiding functional loss due to changes in fence length.

[0047] Synergy between the angle control component and ease of operation: The angle control component, through the cooperation of the arc-shaped groove and the limiting rotation rod, precisely limits the rotation range of the sleeve assembly (e.g., 0° to 90°). 。 This design prevents unnecessary full-circumference rotation of the sleeve assembly during adjustment, ensuring directional and accurate operation and allowing the first and second locking holes to be quickly aligned with the self-made spring seat. On the other hand, this limitation also makes it possible to manually clean the inner surface of the guardrail unit using the sleeve assembly, expanding its functionality.

[0048] In summary, the various features support and enhance each other, forming a technical system that integrates "rapid locking, internal support, collaborative storage, and self-cleaning." Its overall technical effect is far superior to the sum of the effects of using each feature individually.

[0049] Creative explanation of the overall technical solution: This invention has outstanding substantive features and significant progress compared to the prior art, and is inventive.

[0050] 1. Key Substantive Features: In existing technologies, the internal support, locking, and cleaning functions of chain-link fences are typically implemented by separate, independent components, resulting in cumbersome operation and inconvenient storage. This invention creatively proposes a multi-functional integrated technical solution by organically integrating the locking mechanism (hinged shaft, swing seat, sleeve assembly, and self-made spring seat) with the water-spraying structure (first and second flexible permeable sleeves). The core of this solution lies in using a rotatable and retractable sleeve assembly as a carrier to simultaneously achieve three core functions: internal rigid support, rapid locking of multiple fence units, and rainwater-guided self-cleaning. This design concept of "one structure carrying multiple functions" is not a conventional combination that those skilled in the art would easily think of when facing the aforementioned technical problems. It requires breaking away from traditional modular design thinking and deeply coupling and redesigning the structure and working mechanism of each functional component.

[0051] 2. Significant progress: Significantly improved functional integration: This invention highly integrates four major functions—support, locking, cleaning, and storage—into a single mechanism, achieving "multi-purpose functionality," simplifying the overall structure of the fence, and reducing manufacturing costs and complexity.

[0052] Significantly improved operational efficiency: The installation process of the fence only requires a few simple steps, such as unfolding, rotating, stretching, and snapping, to simultaneously complete the establishment of internal supports and the deployment of self-cleaning functions, greatly improving on-site operation efficiency.

[0053] Reduced usage and maintenance costs: The self-cleaning function on the inner surface reduces the frequency and difficulty of manual cleaning; the coordinated storage of the locking mechanism and the fence avoids the loss and damage of parts, extending the overall service life.

[0054] Enhanced structural compactness and reliability: The functional components are rationally laid out and support each other, forming a seamless whole when stored, which not only saves storage and transportation space, but also enhances the overall structural reliability and durability.

[0055] Therefore, this invention neither directly adopts common knowledge or conventional technical means in the field, nor simply pieces together existing technologies. Instead, it solves a long-standing technical problem that has plagued the field through a series of innovative structural designs and deep functional integration, bringing unexpected technical effects and demonstrating significant inventiveness.

[0056] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the claims of the present invention.
