[0002] Road safety features include signal lights, traffic signs, road markings, guardrails, barriers, lighting, sight guidance signs, and anti-glare devices. These features play a vital role in ensuring driving safety and mitigating potential accidents. A well-designed safety system should provide multiple functions, including traffic management, safety protection, traffic guidance, isolation, and glare prevention. Road construction signs, also known as construction signs, construction signs, or movable signs, are a type of road safety device. They are used as protective warnings at road construction sites, during maintenance work, municipal construction, and during construction. They can be placed wherever needed to direct traffic flow, prevent accidental collisions, and minimize losses.

[0003] The main support frame and the auxiliary support frame of the existing road construction sign are usually welded and cannot be folded. This takes up a large space when carried or stored, which is inconvenient. Therefore, it is urgently needed to change. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a foldable road construction sign, comprising a main support frame 1, a sub-support frame 2 rotatably connected to the main support frame 1 through a rotating shaft 4, a positioning plate 3 fixedly connected to the top of the main support frame 1, a mounting groove 301 is opened inside the positioning plate 3, a warning sign 13 is arranged in the mounting groove 301, and the warning sign 13 is detachably installed inside the mounting groove 301, so that the warning sign 13 can be disassembled and replaced, thereby replacing it with a warning sign 13 with different content; a positioning sleeve 5 is fixedly connected to the main support frame 1, and the inner wall of the positioning sleeve 5 is opened with circumferentially distributed arc-shaped card grooves 501, the end of the rotating shaft 4 is fixedly connected to a connecting block 6, and the end of the connecting block 6 is provided with a clamping piece.

[0024] The main support frame 1 and the auxiliary support frame 2 can rotate relative to each other to achieve folding, and the angle of the auxiliary support frame 2 can be locked by cooperating with the arc-shaped slot 501 of the positioning sleeve 5 to prevent the auxiliary support frame 2 from rotating in a natural state; this can reduce the occupied area of ​​the entire product and facilitate carrying or storage.

[0025] Specifically, the clamping part includes a positioning pin 8 inserted in the connecting block 6, an arc-shaped clamping block 7 fixed to the end of the positioning pin 8, and a spring 9 fixed between the arc-shaped clamping block 7 and the connecting block 6. When the angle of the auxiliary support frame 2 is locked, the end of the arc-shaped clamping block 7 is clamped in the arc-shaped clamping groove 501.

[0026] During the process of rotating the auxiliary support frame 2, the connecting block 6 at the end of the rotating shaft 4 can also drive the arc-shaped clamping block 7 to rotate. When the arc-shaped clamping block 7 corresponds to the position of the arc-shaped clamping groove 501, the spring 9 releases the elastic force and pushes the arc-shaped clamping block 7 to be clamped in the arc-shaped clamping groove 501, thereby locking the auxiliary support frame 2.

[0027] In this embodiment, the positioning pin 8 is in the shape of a rectangular rod, which ensures that the arc-shaped block 7 can move linearly; the spring 9 is sleeved on the positioning pin 8, which ensures that the spring 9 can fully release the elastic force to push the arc-shaped block 7 to move linearly.

[0028] In addition, the positioning sleeve 5 is an annular structure, and the arc-shaped clamping groove 501 is provided on the annular groove inside the positioning sleeve 5 .

[0029] Support blocks 10 are fixedly connected to both sides of the positioning plate 3 , and a blocking bar 11 is rotatably connected to the support block 10 , and a pull block 12 is fixedly connected to the end of the blocking bar 11 .

[0030] When the blocking bar 11 rotates to the front side of the warning sign 13 , the warning sign 13 is limited to prevent the warning sign 13 from being separated from the installation slot 301 .

[0031] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
