[0002] Rounded corner guardrail frames are guardrail structures with rounded corner designs, mainly used in architectural decoration, industrial equipment protection, and child safety protection. They are usually made of materials such as metal and plastic, and processed through a certain molding process. Traditional rounded corner guardrail frame manufacturing may require multiple processes, such as cutting, welding, and assembly. However, by using integrated injection molding, the plastic material can be directly injected into the mold to form a complete frame structure in one go, which greatly shortens the production cycle and improves production efficiency.

[0003] Integrated injection-molded rounded corner guardrail frames are usually designed with specialized installation structures, such as screw holes and connecting clips. These structures allow the guardrail frames to be easily connected and fixed to walls, floors, or other building structures. For example, the guardrail frames can be firmly installed on concrete walls using bolts through the screw holes. The installation process is simple and quick, without the need for complicated tools or cumbersome procedures.

[0004] In existing technologies, rounded corner guardrails are connected to ordinary guardrails through bolts or clips for protection. However, the rounded corner area of ​​rounded corner guardrails is generally fixed and difficult to adjust according to the protection area, which reduces the protection flexibility of rounded corner guardrails. To address this issue, an integrated injection-molded rounded corner guardrail frame is proposed. Summary of the Invention

[0030] 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.

[0031] Reference Figures 1-3This utility model provides an embodiment of an integrated injection-molded rounded corner guardrail frame, including a rounded corner guardrail frame one 1, and a rounded corner guardrail frame two 2 disposed on the outer side of the rounded corner guardrail frame one 1. The rounded corner guardrail frame one 1, the rounded corner guardrail frame two 2, the through groove 8, the guide groove 7, the inclined surface 13, and the fixing plate 10 are all integrally injection molded. A protective rod 3 is fixedly connected to the surface of the rounded corner guardrail frame two 2. Several protective rods 3 are provided, and the several protective rods 3 are arranged in pairs in a mirror image with the central axis of the rounded corner guardrail frame one 1 and the rounded corner guardrail frame two 2 as the axis of symmetry. A cavity 4 is opened in the inner wall of the rounded corner guardrail frame one 1, and the cavity 4 can allow the rounded corner rod body 5 to enter. Two sets of rounded corner rod bodies 5 are provided, located at the upper and lower sides of the rounded corner guardrail frame one 1, respectively. At the end, the rounded corner guardrail frame 1 and the rounded corner guardrail frame 2 are both set to the rounded corner arc of the rounded corner rod body 5. The inner wall of the rounded corner guardrail frame 1 is provided with a guide groove 7. The inner wall of the guide groove 7 is slidably connected to a movable frame 6. The outer wall of the movable frame 6 is fixedly connected to the rounded corner rod body 5. The cavity 4 is sleeved on the outer wall of the rounded corner rod body 5. The end of the rounded corner rod body 5 is fixedly connected to the inner wall of the rounded corner guardrail frame 2. The outer wall of the rounded corner guardrail frame 1 is fixedly connected to a fixing plate 10. The inner wall of the fixing plate 10 is threadedly connected to a bolt 12. The outer wall of the rounded corner rod body 5 is provided with a positioning hole 9. Several sets of positioning holes 9 are provided and are evenly distributed on the surface of the two sets of rounded corner rod bodies 5. The inner wall of the positioning hole 9 is threadedly connected to the outer wall of the bolt 12.

[0032] Reference Figures 2-4 The surface of the rounded corner guardrail frame 1 is provided with an adjustment auxiliary component, which includes a blocking rod 11. The end of the blocking rod 11 is fixedly connected to the outer wall of the rounded corner rod body 5. The blocking rod 11 is located in the central area of ​​the rounded corner rod body 5. The surface of the rounded corner guardrail frame 1 is provided with a through groove 8. There are two sets of through grooves 8, and the two sets of through grooves 8 are mirror images of each other. The through grooves 8 are fitted on the outer wall of the blocking rod 11. The opening of the through grooves 8 can prevent the rounded corner rod body 5 from contacting the frame of the rounded corner guardrail frame 1 when it moves.

[0033] Reference Figures 3-4 An inclined surface 13 is provided at the bottom edge of the guide groove 7. The inclined surface 13 is only provided at the edges of the two sets of guide grooves 7 located in the bottom area of ​​the rounded corner guardrail frame 1, so as to avoid dust or impurities accumulating in the groove. An S-shaped through hole 14 is provided on the outer wall of the rounded corner guardrail frame 1. The S-shaped through hole 14 allows dust or impurities smaller than the hole diameter to be discharged naturally through the S-shaped through hole 14. The S-shape setting allows dust or impurities to not overcome their own gravity and flow back into the cavity 4.

[0034] Working principle: The two sets of bolts 12 are reversed in sequence to make them unscrew from the positioning holes 9. At this time, the rounded corner rod 5 is freed from the fixing force and can enter or move out along the cavity 4. When the rounded corner rod 5 moves, it can drive the moving frame 6 to slide inside the guide groove 7, ensuring that the rounded corner rod 5 moves along the predetermined trajectory. When the position is confirmed, the bolts 12 are rotated clockwise to screw them into the corresponding positioning holes 9 to fix the rounded corner rod 5. According to the degree to which the rounded corner rod 5 moves out or into the cavity 4, the radius of the rounded corner guardrail can be flexibly adjusted according to different application scenarios. When the rounded corner rod 5 enters the cavity 4 deeply, the opening of the through groove 8 allows the blocking rod 11 to move, and the blocking rod 11 can be in the gap between the two pairs of protective rods 3, without hindering the movement of the rounded corner rod 5, thus improving the versatility and applicability of the rounded corner guardrail and meeting the protection needs of some special places.

[0035] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
