Description

Technical Field

[0001] This utility model relates to the technical field of highway warning signs, specifically a wind-resistant anti-tilt warning sign. Background Technology

[0002] Warning signs are informational signs used to remind people to pay attention to safety, alerting relevant personnel to dangerous conditions in the workplace or surrounding environment, and guiding people to take appropriate actions. Safety signs can remind workers to prevent dangers, thereby avoiding accidents. When danger occurs, they can instruct people to evacuate as soon as possible, or instruct people to take correct, effective, and powerful measures to contain the harm. Traditional warning signs are easily blown over by the wind or knocked down by minor collisions when outdoors, thus losing their warning effect.

[0003] To address the problem of traditional warning signs being easily blown over by wind or falling over due to minor impacts outdoors, Chinese Patent Publication No. CN204570513U discloses a wind-resistant safety warning sign. This sign includes a sign and a base. The base is welded to the sign using a steel pipe. The base is a hollow hemisphere with a flat plate and a discharge gate at the bottom. One end of the steel pipe is welded to the bottom of the base, and the other end is welded to a triangular steel plate. The base is filled with material. The sign has ventilation holes. Compared to existing technologies, this technology offers the following advantages: 1) a non-tipping design with good wind resistance and stability; 2) flexible use, convenient operation, and labor savings; 3) low manufacturing cost, relatively small structural volume, easy to manage, and reusable.

[0004] The above solutions involve filling the base with high-density materials and punching holes in the warning signs to reduce wind resistance, but they are still susceptible to being knocked over by collisions, especially warning signs on roads. Therefore, we propose a wind-resistant anti-tipping warning sign. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a wind-resistant anti-tilt warning sign, comprising a warning sign, a frame for mounting the warning sign, legs mounted on the frame, and a crossbar mounted between the frame and the legs. The warning sign has several ventilation holes. Clamping mechanisms are provided on both sides of the top of the frame. Each clamping mechanism includes a clamping component, an outer extension arm for mounting the clamping component, an inner extension arm disposed inside the outer extension arm, and a universal component for connecting the inner extension arm and the frame. The inner extension arm and the outer extension arm are nested and slide together, and the clamping component slides in cooperation with the outer extension arm.

[0006] In some embodiments, the clamping assembly includes a sliding connecting block and contact blocks and support blocks mounted on both sides of the sliding connecting block. A contact bolt is provided on the support block, and a turntable is fixed at the outer break point of the contact bolt. The contact bolt is threadedly connected to the support block.

[0007] In some embodiments, the inner extension arm, the outer extension arm, and the sliding connecting block are each provided with a plurality of connecting holes, which are linearly and equally spaced. A fixing pin is provided between the inner extension arm and the outer extension arm, and between the sliding connecting block and the outer extension arm. The inner extension arm and the outer extension arm, and the sliding connecting block and the outer extension arm are connected by the fixing pin.

[0008] In some embodiments, the universal assembly includes a connecting column, a rotating column disposed on the connecting column, a rotating block mounted on the rotating column, and a connecting disk mounted on the other end of the rotating block. The connecting column is rotatably connected to the rotating column, the rotating column is rotatably connected to the rotating block, and the rotating block is rotatably connected to the connecting disk.

[0009] In some embodiments, the other end of the connecting column is fixedly connected to the frame, and the other end of the connecting disc is fixedly connected to the inner extension arm.

[0010] In some embodiments, the legs are rotatably connected to the frame, and the legs are engaged with the frame by a crossbar.

[0011] In some embodiments, the contact block is shaped as a semi-circle and is fitted to the highway guardrail.

[0012] This utility model has at least the following beneficial effects:

[0013] 1. This utility model, through the multi-stage rotation design of the universal component connecting column, rotating column, rotating block and connecting plate in the clamping mechanism, enables the clamping components on both sides to adapt to the high-speed guardrail, especially the bending shape of the guardrail at the curve, and flexibly adjust the clamping angle. With the fine adjustment and fixing function of the contact bolt, it effectively solves the problem of unstable fixing of traditional warning signs due to the irregular shape of the guardrail, and significantly improves the installation adaptability and anti-overturning ability of the warning signs in complex road environments.

[0014] 2. This utility model achieves flexible length adjustment and fixation of the clamping mechanism during use through the nested sliding structure of the inner and outer extension arms and the sliding connection design of the sliding connecting block and the outer extension arm. At the same time, it can be quickly folded and retracted when not in use, which greatly reduces the space occupied by the equipment, facilitates transportation, storage and rapid on-site deployment, and effectively meets the actual needs of warning signs that need to be frequently moved and used.

Detailed Implementation

[0021] 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.

[0022] Example 1:

[0023] Please see Figure 1-5 This utility model provides a technical solution: a wind-resistant anti-tilting warning sign, including a warning sign 5, a frame 4 for mounting the warning sign 5, support legs 2 mounted on the frame 4, and a crossbar 3 mounted between the frame 4 and the support legs 2. The warning sign 5 is provided with a plurality of ventilation holes 6. The top two sides of the frame 4 are provided with clamping mechanisms 1. The clamping mechanism 1 includes a clamping component 14, an outer extension arm 11 for mounting the clamping component 14, an inner extension arm 18 disposed inside the outer extension arm 11, and a universal component 17 for connecting the inner extension arm 18 and the frame 4. The inner extension arm 18 and the outer extension arm 11 are nested and slide, and the clamping component 14 and the outer extension arm 11 are cooperated and slid.

[0024] The warning sign 5 is a core warning component used to display safety information and remind road users of dangers. It achieves high visibility through surface printing or application of reflective materials. Several ventilation holes 6 set on the top can reduce the positive pressure of wind on the warning sign 5, reduce the risk of being blown over by the wind, and at the same time keep the information clear and readable.

[0025] The frame 4 supports the warning sign 5 and connects to other functional components, such as the support legs 2 and the clamping mechanism 1, forming an overall structural skeleton as the main load-bearing structure. The clamping mechanism 1 is installed on both sides of the top and rotates to connect with the support legs 2 at the bottom. The support legs 2 are rigidly fixed after being unfolded by engaging with the crossbar 3, ensuring overall stability.

[0026] The clamping assembly 14 includes a sliding connecting block 143 and contact blocks 141 and support blocks 142 installed on both sides of the sliding connecting block 143. A contact bolt 15 is provided on the support block 142, and a turntable 16 is fixed on the outer end of the contact bolt 15. The contact bolt 15 is threadedly connected to the support block 142.

[0027] The inner extension arm 18, the outer extension arm 11, and the sliding connecting block 143 are each provided with a number of connecting holes 12. The number of connecting holes 12 are distributed linearly and equally. The inner extension arm 18 and the outer extension arm 11, and the sliding connecting block 143 and the outer extension arm 11 are each provided with a fixing pin 13. The inner extension arm 18 and the outer extension arm 11, and the sliding connecting block 143 and the outer extension arm 11 are all connected by the fixing pin 13.

[0028] The outrigger 2 provides ground support for the warning sign 5. The crossbar 3 is used to lock the outrigger 2 in the unfolded state to prevent accidental folding. The outrigger 2 is rotatably connected to the frame 4. When in use, it is rotated downwards to a preset angle. The crossbar 3 is inserted into the groove on the outrigger 2 and the frame 4 to form a triangular support structure, which enhances the anti-overturning ability. When storing, the outrigger 2 can be folded by removing the crossbar 3, which is convenient for transportation.

[0029] The universal assembly 17 includes a connecting post 171, a rotating post 172 disposed on the connecting post 171, a rotating block 173 mounted on the rotating post 172, and a connecting plate 174 mounted on the other end of the rotating block 173. The connecting post 171 is rotatably connected to the rotating post 172, the rotating post 172 is rotatably connected to the rotating block 173, and the rotating block 173 is rotatably connected to the connecting plate 174.

[0030] The sliding connecting block 143 slides with the outer extension arm 11 to adjust the horizontal position of the clamping assembly 14. The fixing pin 13 and the connecting hole 12 are provided with linearly equally spaced connecting holes 12 on the inner extension arm 18, the outer extension arm 11 and the sliding connecting block 143. The adjusted length and position are locked by the fixing pin 13 to ensure structural rigidity.

[0031] The clamping assembly 14 directly contacts and is fixed to the guardrail, providing clamping force. The contact block 141 has a semi-circular design that fits the cylindrical guardrail surface, increasing the contact area and preventing slippage. The support block 142 is threadedly connected to the contact bolt 15. The front end of the bolt contacts the guardrail. The bolt extension length can be adjusted by rotating the turntable 16 to achieve fine-tuning of the clamping force and ensure a firm fixation. The sliding connecting block 143 connects the clamping assembly 14 to the outer extension arm 11. The lateral position can be adjusted by sliding to adapt to different guardrail diameters.

[0032] The other end of the connecting column 171 is fixedly connected to the frame 4, and the other end of the connecting plate 174 is fixedly connected to the inner extension arm 18.

[0033] Universal assembly 17 enables multi-directional angle adjustment of clamping mechanism 1 to adapt to the bending shape of curved guardrail. One end of connecting column 171 is fixed to frame 4, and the other end is rotatably connected to rotating column 172. Rotating column 172 can rotate around the axis of connecting column 171 to adjust the horizontal angle of clamping mechanism 1. Rotating block 173 is rotatably connected to rotating column 172 to adjust the vertical angle. Connecting plate 174 is rotatably connected to rotating block 173 and fixes inner extension arm 18 to realize three-dimensional freedom adjustment of clamping mechanism 1.

[0034] Ventilation holes 6 reduce the positive impact of wind on warning signs 5 and reduce the risk of overturning. By opening regularly arranged holes on the surface of warning signs 5, wind can partially penetrate, reducing the wind resistance coefficient and maintaining structural stability, especially in strong wind environments.

[0035] The synergistic effect is achieved through multi-stage rotation, such as connecting column 171, rotating column 172, rotating block 173 and connecting disk 174. The clamping assembly 14 can adapt to the curved surface of the curved guardrail, ensuring that the clamping points on both sides are symmetrical and the clamping force is uniform.

[0036] Example 2:

[0037] Based on Embodiment 1, this utility model provides a technical solution: a wind-resistant anti-tilting warning sign, wherein the support leg 2 is rotatably connected to the frame 4, and the support leg 2 and the frame 4 are engaged by a crossbar 3;

[0038] The contact block 141 is designed to be semi-circular in shape and fits against the highway guardrail.

[0039] The clamping mechanism 1 fixes the warning sign 5 onto a cylindrical carrier such as a highway guardrail, adapting to the curved shape of the guardrail and solving the problem that the traditional warning sign 5 is prone to tipping over due to collision or irregular guardrail shape. The outer extension arm 11 and the inner extension arm 18 are nested inside the outer extension arm 11. The length can be adjusted by sliding to adapt to guardrails of different widths.

[0040] The warning sign 5 is firmly fixed to the guardrail through the clamping mechanism 1, universal adjustment and telescopic design. With the support legs 2, frame 4 and triangular support on the ground and the wind-resistant design of the ventilation holes 6, it solves the problem of traditional warning signs 5 being easy to tip over. All components work together to adapt to complex road environments, such as curved guardrails, and are easy to fold and store, meeting the needs of frequent movement.

[0041] When the warning sign 5 is unfolded, rotate the support leg 2 to lock the crossbar 3 into the groove on the support leg 2 and the frame 4, and the warning sign 5 is initially fixed. Rotate the clamping mechanism 1 on the warning sign 5 to both sides, and through the universal component 17 on the clamping mechanism 1, the clamping mechanisms 1 on both sides are opened to a preset angle.

[0042] Specifically, the rotating column 172 rotates around the connecting column 171. When it reaches a certain angle, the rotating block 173 rotates relative to the rotating column 172 through the rotating bolt. The connecting plate 174 rotates relative to the rotating block 173. The inner extension arm 18 fixed on the connecting plate 174 rotates with the connecting plate 174. The inner extension arm 18 drives the outer extension arm 11 installed on it to rotate to the preset position.

[0043] After the angle change is completed, the inner extension arm 18 and the outer extension arm 11 slide relative to each other. After sliding to the preset position, they are fixed by the fixing pin 13. The sliding connecting block 143 slides relative to the outer extension arm 11. After sliding to the preset position, it is fixed by the fixing pin 13.

[0044] At this time, place the clamping components 14 on both sides on the highway guardrail, and try to make the contact block 141 fit against the highway guardrail. Rotate the turntable 16 to drive the contact bolt 15 to rotate, so that the front end of the contact bolt 15 contacts the highway guardrail and is fixed firmly. At this time, the frame 4 on the device and the clamping mechanism 1 on both sides form a horizontal triangle, so that the warning sign 5 is fixed on the highway guardrail.

[0045] Since the connecting plate 174 can rotate relative to the rotating block 173, the warning sign 5 may flip over in the vertical direction. Since the support leg 2 and the frame 4 are engaged by the crossbar 3, the frame 4 and the support leg 2 are rigid as a whole. The horizontal triangle at the top of the frame 4, the frame 4 and the support leg 2, and the high-speed ground are engaged. Several ventilation holes 6 are provided on the warning sign 5 to reduce the impact of wind and ensure that the warning sign 5 does not flip over in the vertical direction.

[0046] The design of connecting plate 174 and rotating block 173 allows the two clamping components 14 to adapt to the angle of the warning sign 5 when the device is installed on the guardrail at a high-speed curve. This ensures that the clamping mechanism 1 can firmly clamp the warning sign 5 onto the high-speed guardrail, reducing the occurrence of the warning sign 5 not being firmly clamped due to the bending of the guardrail.

[0047] The sliding connection of the universal joint 17, the inner extension arm 18 and the outer extension arm 11 allows the device to be folded and stored when not in use, which facilitates the disassembly, assembly and transportation of the warning sign 5 and is more in line with the actual use scenarios of the warning sign 5.
