Description

Technical Field

[0001] This invention relates to the field of fencing technology, and in particular to a fencing based on recycled plastic and a manufacturing method thereof. Background Technology

[0002] Municipal construction site fencing is typically made of wood, steel, PVC, or other traditional materials. These materials have the following problems: wooden fencing is prone to rotting, has a short lifespan, requires frequent replacement, and wood resources are limited, posing an environmental impact; steel fencing, while durable, is heavy, has high transportation costs, and suffers from serious rust problems, requiring regular maintenance; PVC fencing has poor durability, and the extensive use of plastic materials can easily cause environmental pollution and is difficult to recycle. Furthermore, existing fencing, due to its fixed assembly angle and inability to rotate, has limitations in its use, reducing its applicability. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings mentioned above by providing a fence based on recycled plastic and its manufacturing method, achieving the advantages of adjustable angle and environmental friendliness.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a fence based on recycled plastic, comprising: The column has a first protrusion on both its left and right sides; The baffle has a second protrusion on both its left and right sides, a first slot on the surface of the second protrusion, and a second slot located outside the first slot on the surface of the second protrusion. A limiting component is provided on the column and the first protrusion to limit and fix the baffle and adjust its angle; The limiting assembly includes a lead screw and a spring. The lead screw is rotatably disposed in the inner cavity of the column, and the spring is disposed in the inner cavity of the first protrusion. The surface of the lead screw is screwed through and extends into the inner cavity of the first protrusion, and the surface of the movable plate is provided with a limiting post that extends through and extends to the outside of the first protrusion. The other end of the spring is connected to a movable post, which passes through the movable plate and the first protrusion and extends to the outside of the first protrusion.

[0005] Furthermore, the end of the first protrusion furthest from the column is an arc surface, and the end of the second protrusion furthest from the baffle is also an arc surface.

[0006] Furthermore, the surface of the lead screw is provided with four sections of thread, and the directions of the four sections of thread are opposite to each other. The top of the lead screw passes through and extends to the top of the column, and a rotating disk is provided at the top of the lead screw.

[0007] Furthermore, the movable plate includes a plate body screwed to the surface of the lead screw, and a ring located in the inner cavity of the first protrusion.

[0008] Furthermore, there are multiple limiting posts, and these multiple limiting posts are distributed in a ring on the surface of the movable plate.

[0009] Furthermore, the movable column consists of two cylinders of different diameters, and the surface of the bottom cylinder slides and fits against the inner cavity surface of the first protrusion.

[0010] Furthermore, the diameter of the second slot is adapted to the diameter of the top cylinder of the movable column, the diameter of the second slot is adapted to the diameter of the limiting column, and the number of the second slots corresponds one-to-one, and the depth of the second slot is less than the depth of the first slot.

[0011] A method for manufacturing a fence based on recycled plastic, the method is as follows: S1. Waste plastics (such as plastic bottles and packaging bags) collected from urban waste recycling stations are processed through washing, crushing, melting and other processes to obtain recycled plastic pellets; S2. Add UV stabilizers, antioxidants, and reinforcing fibers (such as glass fiber and carbon fiber) to recycled plastic granules to improve the material's strength, corrosion resistance, and UV resistance. S3. Using processes such as injection molding or hot pressing, the modified recycled plastics are processed into sheets suitable for municipal fencing. S4. Waterproof and stain-proof treatment shall be applied to the surface of the fencing material.

[0012] The beneficial effects of this invention are reflected in: 1. This invention uses waste plastics as the main raw material, which effectively solves the environmental pollution problem of plastic waste and realizes the recycling of resources. By recycling plastics and modifying them, they meet the requirements for use in municipal fencing and reduce the harm of plastic waste to the ecological environment.

[0013] 2. In use, the present invention, through the cooperation of the limiting component, the first slot, and the second slot, after the column and the baffle are connected, simply rotate the screw to drive the movable column and the limiting column into the corresponding first and second slots, thereby fixing the column and the baffle. When angle adjustment is required, simply rotate the screw in the opposite direction to pull the limiting column out of the second slot. At this time, the connection between the column and the baffle is hinged, so the baffle can rotate. After rotating to a certain angle, simply rotate the screw to re-insert the limiting column into the second slot, thus fixing the column after angle adjustment. The adjustable angle of the baffle allows it to adapt to more usage scenarios. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-6 This invention discloses a fence based on recycled plastic, comprising: The column 1 has a first protrusion 2 on both its left and right sides. The column 1 is a hollow column, and the first protrusion 2 has a cylindrical cavity inside, which is connected to the inner cavity of the column 1. The baffle 8 has a second protrusion 9 on both its left and right sides. The surface of the second protrusion 9 has a first slot 10 and a second slot 11 located outside the first slot 10. There are multiple second slots 11, which are arranged in a ring outside the first slot 10. It should be noted that the depth of the second slot 11 is less than the depth of the first slot 10; The end of the first protrusion 2 away from the column 1 is an arc surface, and the end of the second protrusion 9 away from the baffle 8 is an arc surface. By setting the arc surfaces, the column 1 and the baffle 8 will not be obstructed by the plane when adjusting the angle after assembly, and thus the angle adjustment will not be impossible. A limiting component is provided on the column 1 and the first protrusion 2 to limit and fix the baffle 8 and adjust its angle. The limiting component includes a lead screw 3 rotatably disposed in the inner cavity of the column 1. The surface of the lead screw 3 is provided with four threads, and the directions of the four threads are opposite to each other. The top of the lead screw 3 passes through and extends to the top of the column 1. A rotating disk is provided on the top of the lead screw 3, and a rotating handle is provided on the rotating disk. Under the action of the rotating handle, it is easy to drive the lead screw 3 to rotate. The four threaded surfaces of the lead screw 3 are all screwed with movable plates 4 that penetrate and extend into the inner cavity of the first protrusion 2. The movable plate 4 includes a plate body screwed to the surface of the lead screw 3 and a ring located in the inner cavity of the first protrusion 2. The ring surface of the movable plate 4 is provided with a limiting post 5 that penetrates and extends into the outside of the first protrusion 2. There are multiple limiting posts 5, and the multiple limiting posts 5 are distributed in a ring on the surface of the movable plate 4. At the same time, the diameter of the second slot 11 is adapted to the limiting posts 5, and the number corresponds one to one. The depth of the second slot 11 is less than the depth of the first slot 10, so that the multiple limiting posts 5 are inserted into the corresponding second slot 11. The limiting component also includes a spring 6 disposed in the inner cavity of the first protrusion 2. The other end of the spring 6 is connected to a movable post 7, wherein the spring 6 plays a rebound role, and the diameter of the second slot 11 is adapted to the diameter of the top cylinder of the movable post 7, thereby ensuring that the movable post 7 is inserted into the second slot 11. The movable column 7 passes through the movable plate 4 and the first protrusion 2 and extends to the outside of the first protrusion 2; The movable column 7 consists of two cylinders of different diameters, and the surface of the bottom cylinder slides against the inner surface of the first protrusion 2. Through the sliding contact of the surfaces, the movable column 7 can only move in the direction of the inner cavity of the first protrusion 2. At the same time, through the arrangement of two cylinders of different diameters and the ring through which the movable column 7 passes, the movable plate 4 can only drive the movable column 7 to move when it moves to be in contact with the cylinder of the larger diameter.

[0018] Through the above structural settings: In use, when assembly is required, simply move the two second protrusions 9 on the baffle 8 to the notches of the three first protrusions 2 on the surface of the column 1. Then, by rotating the screw 3, the movable plate 4 is moved. When the movable plate 4 moves, it will move the limiting post 5 and eventually insert it into the corresponding second slot 11. At the same time, since there is no limiting effect from the movable plate 4, the movable post 7 will also be inserted into the corresponding first slot 10 under the action of the spring 6. At this time, the limiting fixation is completed. When the angle needs to be adjusted, simply rotate the screw 3 to pull the limiting post 5 out of the second slot 11. At this time, the movable post 7 is still... Under the action of spring 6, it is inserted into the first slot 10. Since there is no limiting post 5, the baffle 8 can rotate around the limiting post 5 as the central axis to adjust the angle. After the angle adjustment is completed, rotate the screw 3 to make the limiting post 5 re-insert into the second slot 11, so that the angle adjustment can be fixed. When disassembling, rotate the screw 3 to drive the movable plate 4 to move, thereby pulling the limiting post 5 out of the second slot 11. As the movable plate 4 continues to move, the movable plate 4 will drive the movable post 7 to move and be pulled out of the first slot 10. At this time, the column 1 and the baffle 8 can be separated.

[0019] A method for manufacturing a fence based on recycled plastic, the method is as follows: S1. Waste plastics (such as plastic bottles and packaging bags) collected from urban waste recycling stations are processed through washing, crushing, melting and other processes to obtain recycled plastic pellets; S2. Add UV stabilizers, antioxidants, and reinforcing fibers (such as glass fiber and carbon fiber) to recycled plastic granules to improve the material's strength, corrosion resistance, and UV resistance. S3. Using processes such as injection molding or hot pressing, the modified recycled plastics are processed into sheets suitable for municipal fencing. S4. Waterproof and stain-proof treatment shall be applied to the surface of the fencing material.

[0020] Material selection and processing of recycled plastics: Select waste plastics (such as PET bottles, PE bags, PP packaging materials, etc.). These plastics are commonly found in municipal waste and are easy to recycle. The recycled plastics are first cleaned, cleaned, and dried to ensure that oil, dust and other pollutants are removed.

[0021] Crushing and granulation: The cleaned plastic material is crushed and processed into suitable granules by mechanical equipment. Then, the granules are melted using a melt extruder and reprocessed into granules by die extrusion or granulation equipment for subsequent molding and use.

[0022] Modification and reinforcement: Modifiers (such as UV stabilizers, antioxidants, toughening agents, etc.) are added to plastic granules to enhance the plastic's weather resistance and UV resistance. Toughening agents can improve the plastic's impact resistance and abrasion resistance, while UV stabilizers can effectively prevent the plastic from aging under prolonged exposure to sunlight.

[0023] Addition of reinforcing fibers: By adding reinforcing fibers (such as glass fiber, carbon fiber, etc.), the strength and rigidity of the fencing material are enhanced, especially under high wind speed and severe weather conditions, which can maintain the structural stability of the fencing.

[0024] Molding process: Injection molding or thermoforming technology is used to heat the modified plastic granules to a molten state and then inject them into a mold for shaping. These processes ensure the dimensional accuracy of the fencing and provide a smooth surface, suitable for construction needs of various shapes.

[0025] Surface treatment: The surface of the formed fence is sprayed or coated. For example, environmentally friendly water-based paint is used to enhance its anti-pollution ability and waterproof performance, and to avoid aging and damage to the material caused by rain, wind and sand.

[0026] The material proportions are as follows:

[0027] Beneficial effects: Highly environmentally friendly: This invention uses waste plastics as the main raw material, effectively solving the environmental pollution problem of plastic waste and realizing the recycling of resources. By recycling and modifying the plastics, it meets the requirements for use in municipal fencing, reducing the harm of plastic waste to the ecological environment.

[0028] Significant economic benefits: Using recycled plastics reduces raw material costs, effectively lowering production and transportation costs compared to traditional steel, wood, or PVC fencing. Simultaneously, the extended lifespan of the fencing material reduces the frequency of repairs and replacements, further lowering operating and maintenance expenses.

[0029] Improved material durability: By adding reinforcing fibers, UV stabilizers, antioxidants, and other modified components, the municipal fencing material of this invention possesses excellent weather resistance, corrosion resistance, and UV resistance. Even after long-term exposure to outdoor environments, the material maintains good strength and stability, significantly extending its service life.

[0030] Improved construction efficiency: The lightweight design of the fencing material in this invention facilitates transportation and installation, shortening the construction time of the fencing and improving construction efficiency. Its lightweight nature also reduces energy consumption during transportation and handling.

[0031] Meeting Green Building Requirements: This fencing material meets green building material standards and aligns with urban sustainable development requirements, promoting the construction of green buildings and low-carbon cities. It not only aligns with energy conservation and emission reduction goals but also facilitates the widespread application of environmentally friendly materials in municipal engineering projects.

[0032] High recyclability: This material can be recycled at the end of its service life, which is in line with the concept of circular economy and reduces waste.

[0033] Promising market prospects: With increasingly stringent environmental regulations and growing demand for green building materials, the fencing material provided by this invention not only meets environmental protection requirements but also has broad market application potential. It is suitable for various municipal construction, road construction, park fencing, and other fields, and has good promotional value.
