Description

Technical Field

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

[0002] In outdoor work scenarios such as building construction, road maintenance, and municipal engineering, construction signs serve as core safety warning facilities, playing a crucial role in guiding vehicles and pedestrians to avoid obstacles, demarcating work area boundaries, and alerting potential risks. Their effectiveness directly affects the work safety of construction workers and the traffic order of public transportation.

[0003] However, most existing signs are manufactured in one piece, which has a certain impact on storage, transportation, and on-site setup. This phenomenon has become a problem that needs to be solved by people in this field. Utility Model Content

[0004] The purpose of this invention is to provide a foldable construction sign for existing devices, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a foldable construction sign, including a base, a cap on the front side of the base, mounting grooves on the top of the base facing each other, a screw threaded to the middle of the mounting groove, a bracket fixed to the top of the screw, a sliding groove on the inner side of the bracket, three identical indicator plates arranged from top to bottom between the left and right opposing brackets, a rotating shaft rotatably installed between two of the indicator plates, several ventilation holes in the middle of the indicator plate, and connecting blocks arranged on the left and right opposite of the indicator plate.

[0006] This utility model further illustrates that the base is hollow, and the screw cap and the base are connected by threads.

[0007] This utility model further illustrates that the bracket forms a detachable structure through the screw and the mounting groove.

[0008] The present invention further explains that the indicator plate forms a sliding structure between the connecting block and the sliding groove.

[0009] The present invention further explains that the ventilation holes are provided at equal intervals around the center of the indicator plate and are arranged in a matrix.

[0010] This utility model further illustrates that the two rotating shafts are respectively installed at the top and bottom of the central indicator plate.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are: By setting up indicator panels, three sets of indicator panels are connected by rotating shafts. Two of the shafts are installed at the top and bottom of the middle indicator panel, allowing the three sets of indicator panels to be folded and folded along the shafts. The overall thickness after folding is only 1.2-1.5 times the thickness of a single indicator panel, significantly reducing the storage volume. This design makes the signs more suitable for the needs of frequent handling and temporary deployment in construction scenarios. A single person can complete the disassembly, assembly, and transportation, reducing labor costs. Several ventilation holes arranged in a matrix in the middle of the indicator panel can quickly guide airflow in outdoor windy environments, greatly reducing the lateral pressure of the wind on the sign and avoiding the problem of traditional solid signs tipping over or the support deforming due to excessive wind resistance. It is especially suitable for construction scenarios with strong winds, such as highways and open-air factory areas.

[0012] By setting up a bracket, which is threadedly connected to the mounting groove on the top of the base via a screw, a detachable structure is formed. During transportation or storage, the bracket can be separated from the base to prevent damage to the overall structure due to impacts. The base is hollow, and fine sand or liquid can be poured into it for counterweight. It is then sealed with a screw cap thread to achieve overall installation stability. Attached Figure Description

[0014] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0015] Example 1: A foldable construction sign, as shown in the figure, includes a base 1, a cap 2 on the front side of the base 1, mounting grooves 3 on the top of the base 1 facing each other, a screw 4 threadedly connected to the middle of the mounting groove 3, a bracket 5 fixed to the top of the screw 4, a sliding groove 6 on the inner side of the bracket 5, three identical indicator plates 7 arranged from top to bottom between the left and right opposing brackets 5, a rotating shaft 9 rotatably installed between two indicator plates 7, several ventilation holes 8 in the middle of the indicator plate 7, and connecting blocks 10 arranged on the left and right opposite sides of the indicator plate 7.

[0016] The indicator plate 7 forms a sliding structure with the connecting block 10 and the slide 6. When unfolded, the 10 on both sides of the 7 is slidably installed through the 6, ensuring the convenience of overall assembly and disassembly and the stability of unfolding after installation, and ensuring that the whole 7 is kept in the unfolded state for use.

[0017] The ventilation holes 8 are evenly spaced around the center of the indicator plate 7 and arranged in a matrix. This allows for rapid airflow guidance in windy outdoor environments, significantly reducing the lateral pressure of the wind on the indicator plate and avoiding the problem of traditional solid indicator plates tipping over or the support deforming due to excessive wind resistance.

[0018] Two pivots 9 are installed at the top and bottom of the central indicator plate 7 respectively, allowing the three indicator plates to be folded and folded along the pivots 9. After folding, the overall thickness is only 1.2-1.5 times the thickness of a single indicator plate, greatly reducing the storage volume.

[0019] Example 2: Unlike Embodiment 1, the base 1 is hollow, and the screw cap 2 is threadedly connected to the base 1. Fine sand or liquid can be poured into it for counterweight, and the screw cap 2 is then sealed by the threads to achieve overall installation stability.

[0020] The bracket 5 is detachable through the screw 4 and the mounting groove 3. During transportation or storage, the bracket 5 can be separated from the base 1 to avoid damage to the overall structure due to bumps.

[0021] Working principle: First, the bracket 5 is threadedly connected to the mounting groove 3 on the top of the base 1 via the screw 4, forming a detachable structure. During transportation or storage, the bracket 5 can be separated from the base 1 to avoid damage to the overall structure due to impact. The base 1 is hollow, and fine sand or liquid can be poured into it for counterweight. Then, it is sealed by the screw cap 2 to achieve the stability of the overall installation. Next, the three sets of indicator plates 7 are rotatably connected by pivots 9. Two pivots 9 are installed at the top and bottom of the middle indicator plate 7 respectively, allowing the three sets of indicator plates to be folded and retracted along the pivots 9. When unfolded, the 10 on both sides of 7 are slidably installed through 6, ensuring the convenience of overall assembly and disassembly and the stability of the unfolded state after installation, ensuring that the whole 7 is kept in the unfolded state for use. Several ventilation holes 8 arranged in a matrix in the middle of the indicator plate 7 can quickly guide airflow in outdoor windy conditions, greatly reducing the lateral pressure of the wind on the indicator plate and avoiding the problem of traditional solid indicator plates tipping over or the bracket deforming due to excessive wind resistance.
