Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, and in particular to a guardrail accessory that is easy to install. Background Technology

[0002] Currently, guardrails in municipal and transportation sectors generally suffer from problems such as low installation efficiency and inconvenient transportation. Traditional guardrails mostly rely on welding or bolt connections, requiring specialized tools and personnel for on-site assembly. Installation of a single section is time-consuming and labor-intensive. Furthermore, traditional guardrails are mostly fixed, occupying a large space during transportation and resulting in high logistics costs. Frequent disassembly and reassembly of easily damaged components in temporary settings increases maintenance costs.

[0003] While existing folding guardrails attempt to retract, they suffer from drawbacks: some rely on exposed casters or complex locking mechanisms, which are prone to failure due to corrosion; others have limited volume compression when folded, requiring large transport equipment, and lack stability when unfolded. Furthermore, the connecting components have poor anti-loosening properties and limited adaptability, failing to meet the needs of complex environments. Therefore, a convenient guardrail accessory is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a convenient-to-install guardrail accessory, aiming to improve the problems of slow installation, difficult transportation, instability and poor compatibility of guardrails in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An easy-to-install guardrail accessory includes multiple support posts, each of which is rotatably connected to a guardrail plate. Each of the support posts has a rotating plate rotatably connected to both ends. Each of the guardrail plates is fixedly connected to multiple hinges. One end of each hinge is fixedly connected to a second guardrail plate. One end of each rotating plate is rotatably connected to a second rotating plate. Each pair of rotating plates has a common connecting seat rotatably connected to one end. Multiple rotating shafts are fixedly connected to the outside of the connecting seats. An installation assembly for quick guardrail installation is fixedly connected to the outside of the support posts. As a further description of the above technical solution: The mounting assembly includes a female base, which is externally fixedly connected to the outside of one of the support columns, and a male base is externally fixedly connected to the outside of the other support column. The male base has multiple spiral grooves inside, and the female base has multiple bolt shafts rotatably connected inside. As a further description of the above technical solution: When the multiple support columns push against each other, they affect the rotation of multiple rotating plates one and two, thus initiating folding. As a further description of the above technical solution: Both ends of the plurality of guardrail panels are rotatably connected to the outside of the plurality of rotating shafts; As a further description of the above technical solution: Multiple guardrail panels one and two are folded in opposite directions with the connecting seat as the center. As a further description of the above technical solution: The outer surface of the sub-base engages with the groove of the spiral groove, thereby enabling rapid docking; As a further description of the above technical solution: The external rotatable connection of the bolt shaft is to the interior of the male and female seats.

[0006] This utility model has the following beneficial effects: 1. In this utility model, the guardrail accessories achieve folding installation through the linkage of support columns, rotating plates, guardrail panels, and connecting seats. External force drives the support columns to move in opposite directions, causing the rotating plates to deflect, the connecting seats to move, and the guardrail panels to rotate and fold in opposite directions along two axes; the retraction facilitates transportation, and the unfolding quickly forms a protective surface, demonstrating the advantages of dynamic folding.

[0007] 2. In this utility model, the mounting assembly achieves quick locking through a female seat, a male seat, a spiral groove, and a bolt shaft: the male seat is inserted into the female seat, and the bolt shaft engages with the spiral groove to rotate, driving the male seat to feed and engage. The spiral self-locking prevents loosening, and the two-step operation is suitable for folding assembly, balancing convenience and stability. Attached Figure Description

[0010] 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.

[0011] Reference Figures 1 to 3 This utility model provides an embodiment of a conveniently installed guardrail accessory, comprising multiple support columns 1, which are designed as the core load-bearing frame, providing vertical support and serving as a "motion hub". Guardrail plates 2 are rotatably connected to the exterior of each support column 1, forming the main protective surface of the guardrail when unfolded. Rotating plates 3 are rotatably connected to both ends of each support column 1, serving as a linkage hub to trigger folding linkage. Multiple hinges 4 are fixedly connected to the exterior of each guardrail plate 2, serving as angle deflection to prevent damage from rigid collisions during folding and accommodating changes in spatial position during folding. A second guardrail plate 6 is fixedly connected to one end of each hinge 4, forming a continuous protective surface in conjunction with the first guardrail plate 2.

[0012] Multiple rotating plates 3 are rotatably connected to one end of rotating plates 5. The rotating plates 5 are designed to coordinate the folding rhythm of multiple sets of guardrail panels. When multiple support columns 1 push in opposite directions, they affect the rotation of multiple rotating plates 3 and 5, and folding begins. One end of every two rotating plates 5 is rotatably connected to the same connecting seat 7. The connecting seat 7 is designed to converge the movement of two rotating plates 5 and uniformly control the deflection rhythm of multiple sets of rotating plates. Multiple guardrail panels 2 and 6 fold in opposite directions with the connecting seat 7 as the center. Multiple rotating shafts 12 are fixedly connected to the outside of the multiple connecting seats 7. The rotating shafts 12 are designed to provide a rotation fulcrum for the guardrail panels 6 and the connecting seats 7, so that the guardrail panels 6 can deflect around the shaft when the connecting seats 7 move, and complete the "dual-axis coordinated folding" with the hinge 4 to avoid interference between the panels. The outside of the multiple support columns 1 is fixedly connected to the installation components for quick installation of the guardrail. The two ends of the multiple guardrail panels 6 are rotatably connected to the outside of the multiple rotating shafts 12.

[0013] Reference Figure 3 , Figure 4The mounting assembly includes a female base 8, which is designed as a connection reference component, fixed to the outside of one of the support columns 1, providing a mounting carrier and structural support for the entire mounting assembly. It has internal space for rotation. The female base 8 is externally fixedly connected to the outside of one of the support columns 1, while the other support column 1 is externally fixedly connected to a male base 9. The male base 9 is designed as a docking plug, fixed to the outside of the other support column 1, forming a mating interface with the female base 8. Its core function is to insert its own structure into the female base 8, transforming the connection requirement of the two support columns 1 into a mechanical docking of "male base 9 - female base 8," serving as the direct carrier for achieving cross-support column 1 connections.

[0014] The male base 9 has multiple spiral grooves 10 inside. The spiral grooves 10 are designed to serve a dual function of "drive guidance" and "anti-disengagement limit". The outside of the male base 9 engages with the grooves of the spiral grooves 10, thus achieving quick docking. The female base 8 has multiple bolt shafts 11 rotatably connected inside. The bolt shafts 11 are designed as the core components for driving and locking, and are rotatably connected inside the female base 8. Through their own rotation and engagement with the spiral grooves 10, the male base 9 is driven to tighten into the female base 8 using the spiral transmission principle, ultimately achieving a tight fit between the two. At the same time, the self-locking characteristic of the spiral structure can maintain a tight connection without additional external force, preventing loosening. The outside of the bolt shafts 11 is rotatably connected to the inside of the male base 9 and the female base 8.

[0015] Working principle: This guardrail accessory achieves convenient folding installation through the linkage mechanism of support column 1, rotating plate 1 3, rotating plate 2 5, guardrail plate 1 2, guardrail plate 2 6 and connecting seat 7: When an external force drives the support column 1 to move in opposite directions, it acts as a power source, triggering the rotating plate 1 3 at both ends to rotate around the rotating shaft 12 of the support column 1, which drives the hinged rotating plate 2 5 to deflect synchronously; since every two rotating plates 2 5 share a connecting seat 7, the deflection of the rotating plate 2 5 causes the connecting seat 7 to produce a "closer / farther" spatial displacement, forming a linkage-type folding structure. Simultaneously, guardrail panel 2 is rotatably connected to support column 1, and its angle of deflection changes with the spacing of support column 1. Guardrail panel 6 is connected to guardrail panel 2 via hinge 4, and is also hinged to connecting seat 7 via rotating shaft 12. When connecting seat 7 moves, it rotates around hinge 4 and rotating shaft 12 in a dual-axis manner—adapting to the deflection posture of guardrail panel 2 and conforming to the positional changes of connecting seat 7. Ultimately, with connecting seat 7 as the center, guardrail panel 2 and guardrail panel 6 are folded in opposite directions. During the shrinkage phase, support columns 1 move closer to each other, rotating plates 3 and 5 deflect towards the center, connecting seat 7 converges, guardrail panel 2 tilts, and guardrail panel 6 overlaps, resulting in a significant volume reduction for easy logistics and transportation. During installation, the support columns 1 are pushed in the opposite direction to unfold, and each component quickly forms a stable protective surface by utilizing the self-aligning characteristics of the rotatable connection. This "dynamic folding assembly" mode transforms the traditional "static splicing" into mechanical linkage. Through the coordinated action of rotation, hinges, and connecting rods, it achieves the advantages of convenient transportation, efficient installation, and structural stability, greatly simplifying the construction process and reflecting the optimization logic of mechanical structure design for installation efficiency.

[0016] This installation assembly achieves rapid locking via a female connector 8, a male connector 9, a spiral groove 10, and a bolt shaft 11: After the guardrail is unfolded, the male connector 9 on the support column 1 side is aligned with the female connector 8 and inserted. The spiral groove 10 on the surface of the male connector 9 engages with the bolt shaft 11 inside the female connector 8. When the bolt shaft 11 is rotated, the spiral pair utilizes the "rotation → axial displacement" characteristic to drive the male connector 9 to advance along the spiral trajectory into the female connector 8 until it is tightly engaged. The core advantage is that the spiral structure naturally possesses self-locking properties, making the bolt shaft 11 easier to lock under vibration due to the helix angle, rather than loosening, replacing the cumbersome disassembly and assembly of traditional bolts; the two-step operation of "insertion + rotation" not only meets the rapid assembly requirements after the guardrail is folded, but also strengthens the connection strength through mechanical engagement, perfectly connecting the logic of overall folding installation and achieving a balance between convenience and stability.

[0017] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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.
