Description

Technical Field

[0001] This utility model relates to the field of warning sign technology, and in particular to a foldable warning sign. Background Technology

[0002] Warning signs are directional signs used to warn and are generally placed in prominent locations to serve as warnings and reminders. They are widely used, so warning signs often need to be moved. However, some warning signs on the market are fixed structures, meaning their position is fixed after installation, and they need to be disassembled during relocation, which is very inconvenient. Another type is the folding warning sign, which can be folded for easy transport. However, some folding warning signs include a frame for mounting the warning sign with foldable legs. When folding, only the legs can be folded, while the frame itself cannot, resulting in the folded frame still taking up a lot of space, making it inconvenient for storage and transport. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the prior art by providing a foldable warning sign.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0005] A foldable warning sign includes two posts arranged in parallel.

[0006] A support rod is rotatably mounted on the column to support the column.

[0007] Two connecting rods are provided, which are rotatably connected to each other, and the two connecting rods are also rotatably connected to the bottom of the two columns respectively;

[0008] The warning board is detachably and fixedly installed on the two columns.

[0009] Preferably, the support rod has a slot at one end near the column, and the column is locked in the slot when the warning sign is unfolded.

[0010] Preferably, two diagonal tie rods are connected between the two columns, and the two diagonal tie rods are arranged crosswise; each diagonal tie rod includes an upper connecting rod and a lower connecting rod, which are rotatably connected to each other, and the upper connecting rod and the lower connecting rod are rotatably connected to the two columns respectively.

[0011] Preferably, the length of the upper connecting rod is greater than the length of the lower connecting rod.

[0012] Preferably, the column, support rod, and connecting rod are all L-shaped structures.

[0013] Preferably, the lower ends of the column and the support rod are inclined structures.

[0014] Preferably, the warning board is made of a flexible material.

[0015] The beneficial effects of adopting the above technical solution are as follows:

[0016] 1. In this utility model, the connecting rod is rotatably positioned between two columns, and a support rod is rotatably mounted on the columns. During the installation of the warning sign, the two columns are simply stretched in opposite directions to unfold the two connecting rods, which then connect the two columns. The support rod rotates to the other side to support the columns, thus allowing the warning sign to be displayed. When folding, the two columns are moved closer together, folded via the two connecting rods, and finally the support rod is folded. After folding, the entire warning sign has a straight-line structure, which occupies less space and is convenient for transportation and carrying.

[0017] 2. In this utility model, the two diagonal braces can stabilize the columns. After the warning sign is unfolded, the two diagonal braces are arranged in a cross shape, making the two columns more stable. Attached Figure Description

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figures 1 to 3 As shown, a foldable warning sign includes a column 1, a support rod 2, a connecting rod 3, and a warning plate 4. The column 1 is arranged vertically, and there are two columns 1 arranged in parallel. One end of the support rod 2 is rotatably set at the middle or upper part of the column 1, and the support rod 2 is located on the rear side of the column 1. There are two connecting rods 3, and one end of each connecting rod 3 is rotatably connected to the bottom end of the two columns 1 respectively. The two connecting rods 3 are connected end to end and rotatably connected to each other. The connection point between the two connecting rods 3 is located at the middle of the two columns 1. A warning plate 4 is detachably fixed between the two columns 1. The warning plate 4 is printed with warning slogans or patterns to serve as a warning. In this embodiment, the warning plate 4 can be made of flexible materials, such as cloth, non-woven fabric, or plastic sheet, which is convenient for folding and also convenient for printing warning slogans or patterns on the warning plate 4.

[0027] In this invention, when setting up a warning sign, the two pillars 1 are pulled apart in opposite directions until the two connecting rods 3 are straightened and horizontal. Then, the support rod 2 is rotated at a certain angle to the rear of the pillar 1 so that the support rod 2 can support the pillar 1. After unfolding the warning sign, it is placed on the ground with the warning sign tilted to the rear. When folding the warning sign, the support rod 2 is rotated to one side of the pillar 1, and the two pillars 1 are brought together in a direction closer to each other. The two connecting rods 3 are folded from the connection point and rotate relative to each other. Since the warning plate 4 is made of flexible material, it can be folded. The warning sign can finally be folded into a straight structure, which is convenient for handling and transportation and can greatly reduce the area occupied.

[0028] In another embodiment, the warning board 4 is made of a rigid material, such as a wooden board, metal board or plastic board. During installation, the warning board 4 can be fixedly connected to the column 1 with bolts. When folding, the warning board 4 can be removed from the column 1 for replacement. Multiple warning boards 4 can be set, and different warning slogans can be printed on different warning boards 4. The corresponding warning board 4 can be replaced according to different scenarios.

[0029] Furthermore, the connecting rod 3 and the column 1 can be connected by bolts, the two connecting rods 3 can be connected by bolts, and the support rod 2 and the column 1 can also be connected by bolts. When the warning sign is unfolded or folded, the bolts are loosened to allow the connection to rotate freely. When the sign is displayed in the unfolded state, the bolts are tightened to prevent relative rotation and make the warning sign more stable.

[0030] Furthermore, such as Figure 4 As shown, a slot 5 is provided at one end of the support rod 2 near the column 1. When the warning sign is in the unfolded state, the column 1 is locked in the slot 5, which can limit the support rod 2 and prevent the warning sign from tipping over due to excessive rotation angle of the support rod 2, thus failing to play its warning role.

[0031] Furthermore, two diagonal braces 6 are connected between the two columns 1. The two diagonal braces 6 are arranged crosswise. One end of the diagonal brace 6 is rotatably connected to the top of one of the columns 1, and the other end is rotatably connected to the middle or lower part of the other column 1. The diagonal brace 6 and the column 1 can be connected by bolts, which can make the two columns 1 more stable.

[0032] Furthermore, the tie rod 6 includes an upper link 7 and a lower link 8, which are connected end to end and rotatably connected. The upper link 7 and the lower link 8 can be connected by bolts. The end of the upper link 7 away from the lower link 8 is rotatably connected to the top of the column 1, and the end of the lower link 8 away from the upper link 7 is rotatably connected to the middle or lower part of another column 1. In this embodiment, when the warning sign is unfolded or retracted, the upper connecting rod 7, the lower connecting rod 8, and the bolts connecting to the column 1 are loosened. When the warning sign is fully unfolded, the bolts are tightened to fix it. At this time, the upper connecting rod 7 and the lower connecting rod 8 are arranged in a straight line, which can connect the two columns 1 more stably. When the warning sign is retracted, after the bolts are loosened, the two columns 1 are brought closer to each other. The end of the upper connecting rod 7 and the lower connecting rod 8 is rotated, so that the upper connecting rod 7 and the lower connecting rod 8 are folded together. Finally, the warning sign is retracted into a straight line state.

[0033] Furthermore, the length of the upper link 7 is greater than the length of the lower link 8.

[0034] Furthermore, the column 1, support rod 2, and connecting rod 3 are all L-shaped structures, that is, the cross-section of the column 1, support rod 2, and connecting rod 3 perpendicular to their axial direction is L-shaped. The upper connecting rod 7 and lower connecting rod 8 are long strip structures. The column 1, support rod 2, connecting rod 3, upper connecting rod 7, and lower connecting rod 8 are made of metal materials, such as iron or aluminum alloy.

[0035] Furthermore, the lower ends of the column 1 and the support rod 2 are sloped structures. When the warning sign is in the display state, the warning sign is tilted. In order to make the warning sign more stable, the lower ends of the column 1 and the support rod 2 are set as sloped structures, which can increase the contact area with the ground and thus improve stability.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
