Technical Field

[0001] This utility model belongs to the field of highway maintenance and construction technology, specifically relating to a construction warning sign. Background Technology

[0002] During road construction and highway maintenance, warning signs are erected at appropriate locations to alert pedestrians and vehicles to safety. These signs are typically single-layered and single-sided, positioned in a designated direction to warn oncoming pedestrians and vehicles. However, road construction and maintenance areas often include corners and bends. Adding separate warning signs at these locations is inconvenient and ineffective, increasing operational steps, reducing the range of movement for pedestrians and vehicles, and ultimately impacting the effectiveness of the warning system.

[0019] Please see Figures 1-4The present invention provides the following technical solution: including a main warning plate 1 and a support 2, the main warning plate 1 is fixed on the top of the support 2, a secondary warning plate 3 is provided directly above the main warning plate 1, and adjustment and positioning components 4 are provided on both sides of the secondary warning plate 3. The adjustment and positioning components 4 include a fixing block 41, a top frame 42, a bottom block 43 and a connecting rod 44. The bottom block 43 is fixed to the bottom of the top frame 42, and the connecting rod 44 is inserted into the fixing block 41 and connected to the bottom block 43 from below. The fixing block 41 is fixed to the side of the main warning plate 1, and the secondary warning plate 3 is screwed between the two top frames 42.

[0020] In this implementation plan: the main warning plate 1 is connected to the top of the support 2, and the top of the support 2 is fixedly connected to the fixing seat 21. The main warning plate 1 is fixedly connected to the front of the fixing seat 21, so that the main warning plate 1 is stably fixed to the top of the support 2. The support 2 stands on the ground of the construction area to position the main warning plate 1 in the construction area.

[0021] The secondary warning plate 3 is positioned directly above the main warning plate 1. An adjustment and positioning assembly 4 is installed on each side of the secondary warning plate 3, connecting the two assemblies 4 from both sides of the main warning plate 1. Each adjustment and positioning assembly 4 consists of a fixing block 41, a top frame 42, a bottom block 43, and a connecting rod 44. The bottom block 43 is fixedly connected to the bottom of the top frame 42. The top of the fixing block 41 has a connecting hole 411, into which the connecting rod 44 is inserted. The top end of the connecting rod 44 extends above the fixing block 41 and is fixedly connected to the bottom of the bottom block 43, stably connecting the fixing block 41, top frame 42, bottom block 43, and connecting rod 44. The fixing block 41 is fixedly connected to the corresponding side of the main warning plate 1, thus stably connecting the adjustment and positioning assembly 4 to the main warning plate 1. The top frame 42 is snapped onto the corresponding side of the secondary warning plate 3. Two vertically distributed fixing bolts 46 are screwed onto the top frame 42, and the fixing bolts 46 are screwed into the interior of the secondary warning plate 3. The fixing bolts 46 are screwed onto the top frame 42 and the secondary warning plate 3, stably connecting and positioning the secondary warning plate 3 directly above the main warning plate 1. A threaded hole 412 is provided on the side of the fixing block 41, and a fastening screw 45 is screwed into the threaded hole 412. The fastening screw 45 abuts against the outer wall of the connecting rod 44, and the connecting rod 44 is fixed inside the corresponding fixing block 41 by the fastening screw 45, which serves to reinforce the secondary warning plate 3. The connecting rod 44 can move upward inside the corresponding connecting hole 411, allowing the connecting rod 44 to disengage from the corresponding fixing block 41, so that the secondary warning plate 3 can be removed from above the main warning plate 1. The connecting rod 44 can be reset back into the connecting hole 411 on the corresponding fixing block 41. By screwing the fastening screw 45 into the threaded hole 412 on the fixing block 41, the fastening screw 45 can press against the connecting rod 44 to fix the secondary warning plate 3 above the main warning plate 1, so as to facilitate the installation and fixing of the secondary warning plate 3.

[0022] Two symmetrically fixed adjustment and positioning components 4 on both sides of the main warning plate 1 position the secondary warning plate 3 directly above the main warning plate 1. The secondary warning plate 3 is fixed between the two top frames 42 above the main warning plate 1 using screws. The main warning plate 1 is positioned in the construction area by the support 2. The secondary warning plate 3 is positioned above the main warning plate 1 and moves downwards towards it, allowing two connecting rods 44 to be inserted into the connecting holes 411 on the two fixing blocks 41. Fastening screws 45 are then screwed into the two fixing blocks 41 in sequence, with the fastening screws 45 pressing against the connecting rods 44 from the side inside the fixing blocks 41, thus firmly fixing the secondary warning plate 3 above the main warning plate 1. Rotating the fastening screws 45 outwards separates them from the connecting rods 44, allowing the secondary warning plate 3 to move upwards and disengage the connecting rods 44 from the corresponding fixing blocks 41, thus separating the secondary warning plate 3 from the main warning plate 1. This simple operation facilitates the installation, fixing, and removal of the secondary warning plate 3 above the main warning plate 1. After the two connecting rods 44 detach from the two fixing blocks 41, one of the connecting rods 44 can be reset back into the corresponding fixing block 41. This allows the secondary warning plate 3 to rotate above the main warning plate 1. The operator can freely adjust the reset connecting rod 44 to adjust the rotation direction of the secondary warning plate 3 above the main warning plate 1, as well as its position and orientation, effectively positioning it at corners and bends in the construction area. The main warning plate 1 and the adjustable-orientation secondary warning plate 3 form a double-layer warning structure, facilitating convenient and effective expansion of the warning range at corners and bends, enabling multi-directional warning operations, minimizing the movement range of people and vehicles, and improving the construction warning effect. The top of the fixing block 41 is flush with the top of the main warning plate 1 to ensure that the secondary warning plate 3, top frame 42, and bottom block 43 can rotate smoothly above the main warning plate 1. The secondary warning board 3 faces the opposite direction to the main warning board 1, so that after the secondary warning board 3 rotates above the main warning board 1, it can effectively carry out warning operations at the corners and bends of the construction area.

[0023] The working principle and usage process of this utility model are as follows: The main warning plate 1 and the secondary warning plate 3 are positioned in the construction area by the support 2. The fastening screw 45 is rotated outward to separate from the connecting rod 44. The secondary warning plate 3 is moved upward to allow the connecting rod 44 to detach from the corresponding fixing block 41. The secondary warning plate 3 is then separated from the main warning plate 1. After the two connecting rods 44 detach from the two fixing blocks 41, one of the connecting rods 44 is reset back into the corresponding fixing block 41. Then, the secondary warning plate 3 is operated to rotate above the main warning plate 1. The operator can freely adjust the reset connecting rod 44 to adjust the rotation direction of the secondary warning plate 3 above the main warning plate 1, adjust the position and orientation of the secondary warning plate 3, and adjust the secondary warning plate 3 to the corners and bends in the construction area. The main warning plate 1 and the secondary warning plate 3 with its orientation adjusted above form a double-layer warning structure to complete multi-directional warning operations.
