[0002] Plastic products are a general term for household and industrial goods made primarily from plastics. This includes products manufactured using processes such as injection molding and vacuum forming. Plastics are a type of synthetic polymer material with plasticity. During construction, to prevent outsiders from entering hazardous construction areas, guardrails are typically installed around the construction site to protect pedestrians. With technological advancements, plastic guardrails are increasingly being used on construction sites for safety protection.
[0003] Unlike metal fences, which can be welded or bolted together, most plastic fences are typically one-piece structures. This makes them difficult to disassemble, inconvenient to transport, and the process is more complex and less efficient.
[0004] Therefore, a plastic anti-fall railing that is easy to disassemble and quickly fixed is proposed. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To overcome the shortcomings of existing technologies, a plastic anti-fall railing is proposed to address the problem that, unlike metal railings which can be welded or bolted together, most plastic railings are generally of a one-piece structure, making them inconvenient to disassemble and transport, and the safety process is also relatively complex and inefficient.
[0007] (II) Technical Solution
[0008] This utility model is achieved through the following technical solution: This utility model proposes a plastic anti-fall railing, including fixed posts and railings connecting the posts for anti-fall purposes.
[0009] The column has a through central groove inside, and symmetrically arranged inwardly extending side sliding grooves on both sides of the central groove. A door-shaped push slide is slidably connected inside the side sliding groove. The top of the push slide is provided with an up-and-down pushing mechanism for pulling up and down. Several lower placement plates are fixedly connected inside the central groove. An upper clamping plate is movably provided at the upper end of the lower placement plate, and the side of the upper clamping plate is connected to the push slide through a connecting block. The lower placement plate and the upper clamping plate have limiting grooves on their corresponding surfaces, and the railing is placed inside the limiting groove.
[0010] Furthermore, the bottom end of the column is connected to a connecting base plate, and the outer side of the connecting base plate is provided with fixing holes.
[0011] Furthermore, the up-and-down pushing mechanism includes a threaded connection hole penetrating the top of the column, and a lead screw is connected inside the threaded connection hole. The bottom end of the lead screw is connected to the top of the pushing slide through a bearing, and a knob is connected to the top of the lead screw.
[0012] Furthermore, the top of the column is provided with a connecting threaded groove on the outer side, the top of the column is provided with a cover cylinder, and the bottom end of the cover cylinder is provided with threads that connect with the connecting threaded groove.
[0013] Furthermore, the column is symmetrically provided with sliding cavities inside, and the bottom of the side sliding groove passes through them. A sliding baffle is slidably provided inside the sliding cavity, and the bottom end of the push carriage is connected to the sliding baffle.
[0014] Furthermore, the lower placement plate and the upper clamping plate are extended outwards.
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model has the following advantages:
[0017] In this invention, after the railing is placed inside the limiting groove at the lower placement plate, the screw is turned to push the slide downwards and move the upper clamping plate. This allows the upper clamping plate and the lower placement plate to clamp and fix the railing together, thus assembling the railing. This makes the operation simpler and facilitates quick assembly and disassembly, avoiding the situation where the integrated design is difficult to disassemble and transport, and making the work more efficient.

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.
[0027] Please see Figures 1-6 This utility model provides a plastic anti-fall railing, including a fixed column 1, a connecting base plate 2 connected to the bottom end of the column 1, and a fixing hole provided on the outer side of the connecting base plate 2 to facilitate fixing the column 1 and improve its stability during protection, and a railing 8 connecting the columns 1 for anti-fall purposes. Under the action of the column 1, the railing 8 is horizontally positioned so that the railing 8 can perform the anti-fall work.
[0028] The column 1 has a through central groove 3 inside, which facilitates the vertical movement of the upper clamping plate 6, allowing it sufficient distance to move and clamp different railings 8. Symmetrically arranged on both sides of the central groove 3 are inwardly penetrating side slide grooves 4. A gate-shaped pusher slide 9 is slidably connected inside the side slide grooves 4, preventing lateral swaying during operation and allowing only vertical movement. This facilitates stable operation. The top of the pusher slide 9 has a vertical pushing mechanism for pulling the upper clamping plate 6. Several lower placement plates 5 are fixedly connected inside the central groove 3, allowing for the placement of multiple railings 8. To enhance protection, an upper clamping plate 6 is movably mounted on the upper end of the lower placement plate 5. The side of the upper clamping plate 6 is connected to the push slide 9 via a connecting block, so that the push slide 9 drives the upper clamping plate 6 to move up and down together with the lower placement plate 5 to fix and clamp the railing 8. The lower placement plate 5 and the upper clamping plate 6 have corresponding limiting grooves 7, and the railing 8 is placed inside the limiting grooves 7, making the railing 8 more stable when placed and preventing it from slipping out during clamping. A baffle can be set in the middle of the outermost limiting groove 7 to prevent it from sliding outward. The lower placement plate 5 and the upper clamping plate 6 are extended on the outside, thereby increasing the placement surface of the railing 8, making it more stable and better fixed.
[0029] Preferably, the up-and-down pushing mechanism includes a threaded connection hole 10 penetrating the top of the column 1, and a lead screw 11 is connected inside the threaded connection hole 10. The bottom end of the lead screw 11 is connected to the top of the push slide 9 through a bearing, and a knob is connected to the top of the lead screw 11. By turning the knob, the lead screw 11 is rotated through the threaded connection hole 10 to pull the push slide 9 up and down, thereby causing the push slide 9 to drive the upper clamping plate 6 to move up and down. This enables the disassembly and fixing of the railing 8, making the operation simpler, easier to disassemble, and easier to transport. A connecting threaded groove 13 is provided on the outer side of the top of the column 1, and a cover cylinder 12 is provided on the top of the column 1. The bottom end of the cover cylinder 12 is provided with threads that connect to the connecting threaded groove 13, thereby connecting and fixing the cover cylinder 12 so that the cover cylinder 12 covers the upper end of the lead screw 11, preventing it from being loosened by external factors when not in use.
[0030] Preferably, the column 1 has symmetrical sliding cavities 14 inside, and the bottom of the side sliding groove 4 passes through them. A sliding baffle 15 is slidably provided inside the sliding cavity 14, and the bottom end of the push carriage 9 is connected to the sliding baffle 15. In this way, the sliding baffle 15 prevents the lower end from running out, which would cause inconvenience for subsequent insertion, thus making the stability better.
[0031] Working principle: In use, first turn the knob to rotate the screw 11 to pull the slide 9 upward, causing the upper clamping plate 6 to separate from the lower placement plate 5. Then, place the railing 8 in the limiting groove 7 inside the lower placement plate 5. Then, turn the knob to rotate the screw 11 in the opposite direction, causing the slide 9 to move downward through the threaded connection hole 10, thus moving the upper clamping plate 6. The upper clamping plate 6 clamps and fixes the railing 8 with the lower placement plate 5. Then, the cover cylinder 12 is rotated and fixed through the connecting thread groove 13, thus completing the work.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
