Description

Technical Field

[0001] This utility model belongs to the field of courtyard fence technology, specifically relating to a powder-coated fence for courtyard protection and decoration that is easy to assemble. Background Technology

[0002] Powder-coated fences are fence products that use electrostatic spraying technology to attach powder coatings to the surface of a metal substrate and then cure them at high temperatures to form a protective and decorative coating. The core process is to use high voltage electrostatics to make powder particles evenly adsorbed on the metal surface, and then melt and level them at a high temperature of over 200°C to form a dense coating with a thickness of about 60-80 micrometers.

[0003] Powder coating technology not only gives fences excellent anti-corrosion properties (such as salt spray resistance and UV resistance), but also enables a variety of decorative effects, such as high gloss, matte, sand texture, or crackle texture.

[0004] However, while most current courtyard protective and decorative fences can meet general usage needs, their height is not adjustable, which reduces their aesthetic appeal.

[0005] A search revealed that Chinese utility model patent with authorization announcement number CN221856416U discloses "a decorative plant fence for a courtyard", which includes several fences, several connecting parts, a drive motor, a drive assembly and a transmission assembly. The two ends of each connecting part are detachably connected to the corresponding fence and are located at one end of the corresponding fence. One end of the drive assembly is drively connected to the output end of the drive motor and is located at one end of the drive motor.

[0006] While existing courtyard protective decorative fences, including those mentioned above, can adjust the height of the fence, they are not convenient for splicing the fences, and it is not convenient to reinstall repaired or new fences for damaged fences.

[0007] To address the aforementioned issues, this application proposes a powder-coated fence for courtyard protection and decoration that is easy to assemble. Utility Model Content

[0034] 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.

[0035] Please see Figures 1-5 The present invention provides the following technical solution: a powder-coated fence for courtyard protection and decoration that is easy to splice, including a supporting beam 1, and also including: multiple splicing uprights 2, splicing beams 3, multiple protective fences 4 and a first locking bolt 6.

[0036] Furthermore, by Figure 1 , Figure 2 and Figure 4 As shown in this embodiment, multiple splicing uprights 2 are equally spaced on the top of the supporting beam 1. Two sets of first positioning grooves 21 are equally spaced along the vertical direction on all splicing uprights 2. Two splicing beams 3 are spaced between any two adjacent splicing uprights 2. C-shaped parts 31 for clamping the sides of the splicing uprights 2 are provided at both ends of the splicing beams 3. Multiple protective fences 4 are equally spaced between two splicing beams 3. Second inserts 41 are provided at the top and bottom of the protective fences 4. Second slots 32 for the second inserts 41 to be inserted are opened on the splicing beams 3. The first locking bolts 6 are installed on the C-shaped parts 31 by thread engagement, and one end of the first locking bolts 6 is embedded in the first positioning grooves 21. With the above scheme, when in use, the supporting beams 1 are first fixed to the courtyard foundation by embedded parts or expansion bolts as the horizontal load-bearing foundation of the entire fence.

[0037] Multiple splicing uprights 2 are vertically installed on the top of the supporting beam 1 at the designed spacing. The two sets of vertically distributed first positioning grooves 21 on the splicing uprights 2 provide multiple options for the height adjustment of the subsequent splicing beam 3. The spacing between the upper and lower splicing beams 3 and the overall installation height can be adjusted according to the protection requirements.

[0038] When installing the splicing beam 3 between adjacent splicing uprights 2, the C-shaped parts 31 at both ends of the beam are used to clamp the side of the splicing upright 2 from the side.

[0039] Then, the first locking bolt 6 is screwed in. After its screw passes through the threaded hole of the C-shaped part 31, the tapered end gradually embeds into the first positioning groove 21. As the first locking bolt 6 is tightened, the inner arm of the C-shaped part 31 generates friction with the side of the splicing upright plate 2. At the same time, the mechanical engagement between the end of the first locking bolt 6 and the first positioning groove 21 forms a double lock, ensuring that the splicing crossbeam 3 has no displacement in the horizontal direction and that the height is adjustable in the vertical direction through multiple sets of first positioning grooves 21.

[0040] The second insert 41 at the top and bottom of the protective fence 4 is aligned with the second slot 32 on the splicing crossbeam 3. By pressing or tapping, the second insert 41 is fully inserted into the second slot 32. The fit between the second insert 41 and the second slot 32 adopts an interference fit or dovetail groove structure to prevent the protective fence 4 from shaking in the horizontal direction, while retaining a certain degree of freedom of insertion and removal for later maintenance.

[0041] The spacing between adjacent protective fences 4 is precisely controlled by the second slot 32 on the splicing beam 3 to form a uniform protective interval. When subjected to external impact, the impact force is transmitted to the splicing beam 3 through the protective fence 4, and then dispersed to the supporting beam 1 and the foundation through the C-shaped part 31 and the splicing upright plate 2, avoiding single-point force damage.

[0042] The entire installation process can be completed without welding or complicated tools, and damaged splicing uprights 2, splicing beams 3, or protective fence 4 components can be quickly replaced.

[0043] When the fence height needs to be adjusted or the layout needs to be rearranged, simply loosen the first locking bolt 6, move the splicing beam 3 up and down to the target first positioning groove 21, and then tighten the first locking bolt 6 to complete the height adjustment.

[0044] All components of the fence are made of metal (such as stainless steel, aluminum alloy, etc.), and the surface is treated with powder coating to extend its service life.

[0045] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, the outer wall of the splicing upright plate 2 is attached to the inner wall of the C-shaped part 31. After adopting the above solution, the shear resistance is greatly improved compared with point contact or line contact connection. When the fence is subjected to lateral thrust (such as wind force or impact force), the load is evenly transmitted to the surface of the splicing upright plate 2 through the inner wall of the C-shaped part 31, avoiding local deformation caused by stress concentration or loosening of the first locking bolt 6, and further improving stability.

[0046] Preferably, by Figure 1 and Figure 4 As shown, in this embodiment, the outer wall of the second insert 41 is attached to the inner wall of the second slot 32. With the above solution, the shear resistance is greatly improved compared with point contact or line contact connection. When the fence is subjected to lateral thrust (such as wind force or impact force), the load is transferred to the splicing beam 3 through the second insert 41, and then transferred to the surface of the splicing upright plate 2 by the C-shaped part 31 of the splicing beam 3, avoiding stress concentration and further improving stability.

[0047] In addition, the installation of the protective fence 4 does not require any other locking components. The stability of the protective fence 4 is ensured by the "mortise and tenon structure" formed by the second insert 41 and the second slot 32, as well as the clamping force of the two splicing crossbeams 3.

[0048] Optionally, by Figure 1 and Figure 3As shown, this embodiment also includes: a first insert 22 and a second locking bolt 7. The first insert 22 is fixed to the bottom end of the splicing upright plate 2, and a second positioning groove 221 is provided on the first insert 22. A first slot 11 for the first insert 22 to be inserted is provided on the supporting beam 1. A first threaded hole 12 is machined on the supporting beam 1. The second locking bolt 7 is threadedly engaged with the first threaded hole 12, and one end of the second locking bolt 7 is embedded in the second positioning groove 221. With the above solution, when in use, the first insert 22 at the bottom end of the splicing upright plate 2 is pre-fixed to the splicing upright plate 2 by welding, and its cross-sectional shape is completely matched with the first slot 11 at the top of the supporting beam 1.

[0049] During installation, align the splicing upright plate 2 vertically with the supporting crossbeam 1, and slide the first insert 22 axially along the guide slope of the first slot 11 to quickly complete the initial positioning.

[0050] Finally, the second locking bolt 7 is screwed in. The second locking bolt 7 is threaded into the first threaded hole 12. As the second locking bolt 7 is screwed in, one end of the second locking bolt 7 is embedded in the second positioning groove 221 to achieve axial positioning. At the same time, it applies a compressive force to the first insert block 22 to perform radial locking, ensuring the stability of the connection between the splicing upright plate 2 and the supporting crossbeam 1.

[0051] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, the outer wall of the first insert 22 is attached to the inner wall of the first slot 11. After adopting the above solution, the shear resistance is greatly improved compared with point contact or line contact connection. When the fence is subjected to lateral thrust (such as wind force or impact force), the load is transferred to the support beam 1 through the first insert 22, avoiding the deformation of the support beam 1 caused by stress concentration, and further improving stability and safety.

[0052] Preferably, by Figure 1 and Figure 5 As shown in this embodiment, a splicing block 13 is fixed at one end of the supporting beam 1, and a splicing groove 14 for the splicing block 13 to be embedded is provided at the other end. A limiting hole 131 is provided on the splicing block 13, and a second threaded hole 15 communicating with the splicing groove 14 is machined on the supporting beam 1. With the above solution, when in use, the splicing block 13 of the supporting beam 1 adopts a rectangular or dovetail shape that matches the splicing groove 14. Both the splicing block 13 and the splicing groove 14 of this utility model are rectangular. Therefore, when splicing adjacent supporting beams 1, the splicing block 13 can be inserted into the splicing groove 14 in either a vertical or horizontal direction.

[0053] After insertion, the limiting hole 131 corresponds to the second threaded hole 15. The splicing block 13 can be locked by screwing in the bolt, which improves the stability of the two adjacent support beams 1 after splicing.

[0054] Preferably, by Figure 1 and Figure 5 As shown, in this embodiment, the outer wall of the splicing block 13 is attached to the inner wall of the splicing groove 14. After adopting the above solution, when in use, the splicing block 13 and the splicing groove 14 form a "mortise and tenon" interlocking structure. Compared with point contact or line contact connection, the shear resistance is greatly improved, and the overall stability of the connection of different support beams 1 is improved.

[0055] Preferably, by Figure 1 As shown, this embodiment also includes: multiple reinforcing bars 5, which are fixed at equal intervals to the bottom of the supporting beam 1. With the above solution, during use and installation, the multiple reinforcing bars 5 are directly embedded in the concrete foundation to form the pre-embedded supporting beam 1, which greatly improves the installation stability of the fence.

[0056] Components not described in detail in this article are existing technologies.

[0057] The working principle and usage process of this utility model: When using the fence of this utility model, the supporting beam 1 is first fixed to the courtyard foundation by embedded parts or expansion bolts, which serves as the horizontal load-bearing foundation of the entire fence.

[0058] Multiple splicing uprights 2 are vertically installed on the top of the supporting beam 1 at the designed spacing. The two sets of vertically distributed first positioning grooves 21 on the splicing uprights 2 provide multiple options for the height adjustment of the subsequent splicing beam 3. The spacing between the upper and lower splicing beams 3 and the overall installation height can be adjusted according to the protection requirements.

[0059] When installing the splicing crossbeam 3 between adjacent splicing vertical panels 2, the C-shaped parts 31 at both ends of the crossbeam 31 are used to clamp the side of the splicing vertical panel 2 from the side.

[0060] Then, the first locking bolt 6 is screwed in. After the bolt passes through the threaded hole of the C-shaped part 31, the tapered end gradually embeds into the first positioning groove 21. As the first locking bolt 6 is tightened, the inner arm of the C-shaped part 31 generates friction with the side of the splicing upright plate 2. At the same time, the mechanical engagement between the end of the first locking bolt 6 and the first positioning groove 21 forms a double lock, ensuring that the splicing crossbeam 3 has no displacement in the horizontal direction and that the height is adjustable in the vertical direction through multiple sets of first positioning grooves 21.

[0061] The second insert 41 at the top and bottom of the protective fence 4 is aligned with the second slot 32 on the splicing crossbeam 3. By pressing or tapping, the second insert 41 is fully inserted into the second slot 32. The fit between the second insert 41 and the second slot 32 adopts an interference fit or dovetail groove structure to prevent the protective fence 4 from shaking in the horizontal direction, while retaining a certain degree of freedom of insertion and removal for later maintenance.

[0062] The spacing between adjacent protective fences 4 is precisely controlled by the second slot 32 on the splicing beam 3 to form a uniform protective interval. When subjected to external impact, the impact force is transmitted to the splicing beam 3 through the protective fence 4, and then dispersed to the supporting beam 1 and the foundation through the C-shaped part 31 and the splicing upright plate 2, avoiding single-point force damage.

[0063] The entire installation process can be completed without welding or complicated tools, and damaged splicing uprights 2, splicing beams 3 or protective fences 4 can be replaced quickly;

[0064] When it is necessary to adjust the height of the fence or rearrange it, simply loosen the first locking bolt 6, move the splicing beam 3 up and down to the target first positioning groove 21, and then tighten the first locking bolt 6 to complete the height adjustment.

[0065] All components of the fence are made of metal (such as stainless steel, aluminum alloy, etc.), and the surface is treated with powder coating to extend its service life.

[0066] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
