[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0014] Example: See Figure 1-4 This utility model discloses a safety guardrail structure for a recreational vehicle, comprising a left fan frame 1, with a right fan frame 2 symmetrically arranged on one side of the left fan frame 1. Multiple arc-shaped through slots are evenly distributed on the left fan frame 1 and the right fan frame 2, and multiple reinforcing ribs 3 are fixedly connected between the arc-shaped through slots. Multiple left-braided ropes 4 are equidistantly fixed to the upper outer wall of the left fan frame 1, and multiple right-braided ropes 5, corresponding to the positions of the left-braided ropes 4, are equidistantly fixed to the upper outer wall of the right fan frame 2. The left fan frame 1 and the right fan frame 2 are made of plastic, which is lightweight and has a certain strength. This design reduces the overall weight of the guardrail while ensuring basic structural stability. The reinforcing rib 3 is also made of plastic, matching the material of the left and right side frames 1 and 2, facilitating integral molding and enhancing the structural strength of the left and right side frames 1 and 2, preventing deformation. This section of the structure, through the combination of the arc-shaped groove and the reinforcing rib 3, reduces weight while improving the overall structural stability, providing fundamental support for the protective function. Both the left and right braided ropes 4 and 5 are arranged in an arc shape. The woven rope 5 is made of nylon braided belt, which has good flexibility and wear resistance, and a long service life. The arc-shaped left and right woven rope belts 4 and 5 can better conform to the contours of the rear wheel of the recreational vehicle, increasing the protection range and improving the overall protection. Multiple fixing holes are equidistantly opened on the opposite surfaces of the left and right woven rope belts 4 and 5. A winding box 6 is located at the upper end of the left woven rope belt 4. Two rotating shafts 7 are horizontally mounted inside the winding box 6. Both the upper and lower ends of the winding box 6 have openings. One end of the cable extends into the winding box 6 and is wound in an S-shape around the two rotating shafts 7, extending beyond the top of the winding box 6. The winding box 6 is made of ABS plastic, which has good mechanical properties and corrosion resistance, and a long service life. The rotating shafts 7 are made of 45# steel, which has high hardness and good wear resistance, ensuring smooth rotation. This structure allows for flexible adjustment of the extension length of the left braided rope 4 by winding it in an S-shape around the rotating shaft 7, making it easy to adjust the opening and closing degree of the guardrail according to actual needs and improving ease of use.
[0015] In this utility model, two locking blocks 8 are fixedly and mirror-connected to the top of the winding box 6. A limiting plate 9 is fixedly connected to the top of the winding box 6 between the opposite surfaces of the two locking blocks 8. Both the locking blocks 8 and the limiting plate 9 are made of PP plastic. PP plastic has good toughness and a certain degree of elasticity, which facilitates the locking blocks 8 to engage and disengage from the slots of the rectangular box 12. The locking blocks 8 and the limiting plate 9 cooperate to enhance the stability of the connection between the winding box 6 and the rectangular box 12 when the guardrail is closed, prevent accidental detachment, and ensure the protective effect. Multiple threading frames 10 are equidistantly provided on the opposite surfaces of the right braided rope 5 and the left braided rope 4. Multiple docking holes are equidistantly opened in the middle of the top surface of the threading frame 10. One end of the docking hole passes through the outer wall of one side of the right braided rope 5. A limiting rod 11 passes through the docking hole. One end of the limiting rod 11 is fixedly connected to a limiting plate located on the top surface of the threading frame 10. The other end of the limiting rod 11 is fixedly connected to two mirror-connected expansion protrusions located on the outer wall of one side of the right braided rope 5. A gap is provided between the protrusions, and the diameters of the mating holes and fixing holes are the same. The material of the strap frame 10 is PVC plastic, which has high strength and low cost. The material of the limiting rod 11 and the expansion protrusion is polyethylene, which has good plasticity and toughness, and the expansion protrusion can reliably lock in place. This structure achieves a stable connection between the left braided rope 4 and the right braided rope 5 by having the limiting rod 11 pass through the mating hole and the fixing hole and using the expansion protrusion to lock in place. This avoids the problem of easy breakage of the Velcro and improves the reliability of the connection and the safety of the protection. A rectangular box 12 is fixedly attached to the top of the right braided rope 5. The top of the rectangular box 12 has an opening, and two slots corresponding to the two locking blocks 8 are symmetrically opened on both sides of the inner wall of the rectangular box 12. The material of the rectangular box 12 is polycarbonate, which has strong impact resistance and good dimensional stability. The slots of the rectangular box 12 cooperate with the locking blocks 8 of the winding box 6 to quickly achieve the initial fixation of the guardrail, which facilitates subsequent connection operations and improves assembly efficiency.
[0016] Working principle: When using this utility model, first place the left fan frame 1 on the left side of the rear wheel of the recreational vehicle, then install the right fan frame 2 on the right side of the rear wheel of the recreational vehicle. Next, align the locking block 8 on the right fan frame 2 with the rectangular box 12 to complete the initial fixation of the main frame of the guardrail. Then, pull the left braided rope 4, and rotate the two rotating shafts 7 inside the winding box 6 to release the left braided rope 4, which is wrapped in an S-shape on the rotating shafts 7. Adjust the extension length of the left braided rope 4 to a suitable degree according to the protection requirements. Then, insert the pulled-out left braided rope 4 part into the threading frame 10. At the last threading frame 10 with the left braided rope 4, align the fixing hole on the left braided rope 4 with the docking hole on the threading frame 10, and set the limiting rod. 11 is inserted through the docking hole on the top surface of the threading frame 10 and passes through the fixing hole. The two expansion protrusions at the end of the limiting rod 11 are squeezed as they pass through the holes of the same diameter. After passing through the outer wall of the right braided rope 5, it returns to its original shape. The expansion protrusions are used to lock the outer wall of the right braided rope 5. At the same time, the limiting plate abuts against the top surface of the threading frame 10, realizing a stable connection between the left braided rope 4 and the right braided rope 5. If it is necessary to open the guardrail, press the expansion protrusion at the end of the limiting rod 11 to make it retract, pull the limiting rod 11 out from the docking hole and the fixing hole, and then press the two locking blocks 8 at the top of the winding box 6 so that the two locking blocks 8 abut against the limiting plate 9, and then separate from the rectangular box 12. The left braided rope 4 can be retrieved through the winding box 6. At this point, the device is in use.
[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
