DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0014] As Figure 1 and 2 shown, the road construction safety guardrail is an improvement on the existing guardrail and is also made of stainless steel material as a whole. The road construction safety guardrail includes a guardrail body 1, 1 crossbar 2, and 4 vertical rods 3. Among them, the guardrail body 1 is in an n shape, the crossbar 2 is connected to the lower parts on both sides of the guardrail body 1, and the vertical rods 3 are connected between the upper side of the crossbar 2 and the lower side in the middle of the n-shaped guardrail body 1. An inverted V-shaped support foot 6 is provided at the bottom of the guardrail body 1, and the guardrail body 1, the crossbar 2, the vertical rods 3, and the support foot 6 are all made of stainless steel pipes, and the connection method between them is welding. These structures are similar to those of the existing road guardrail and will not be elaborated here.

[0015] The improvements of this product are as follows: It further includes a warning board 4, which is also made of stainless steel plate. The front of the warning board 4 is a warning area, and different warning messages can be displayed in the warning area by means of engraving, pasting colored tapes, handwriting, etc. The warning messages are, for example, road construction, no littering, no crossing, etc. At the back of the warning board 4, there is a C-shaped snap ring 41 with an opening facing backward, and the C-shaped snap ring 41 can be snap-fitted onto the vertical rod 3. Preferably, there are two C-shaped snap rings 41, and the two C-shaped snap rings 41 are respectively connected to the two vertical rods 3. The C-shaped snap ring 41 is provided with an elastic layer 42 on the surface that is in close contact with the vertical rod 3, and the elastic layer is made of rubber material. The surfaces of the guardrail body 1 and the cross bar 2 are provided with a reflective layer 7, and the reflective layer 7 can be selected from existing reflective films, reflective stickers, etc.

[0016] In order to further improve the stability of the installation of this product, therefore, a weighted base 5 is provided at the bottom of the support foot 6. The weighted base 5 is cylindrical, and the weighted base 5 is a solid stainless steel block. At the bottom of the weighted base 5, there is a rubber anti-slip layer 51, which is pasted on the bottom surface of the weighted base 5. On the bottom surface of the rubber anti-slip layer 51, there are anti-slip protrusions 52, which are semi-circular. At the top of the weighted base 5, there is a threaded post 53, and the outer wall of the threaded post 53 is provided with external threads. At the bottom of the support foot 6, there is a threaded hole, and the inner wall of the threaded hole is provided with internal threads, and the threaded hole is threadedly connected to the threaded post 53.

[0017] In addition, in order to facilitate the connection of adjacent road construction safety guardrails, a 7-shaped plug-in 11 is provided on the right side of the guardrail body 1, and a vertical socket 12 is provided on the left side of the guardrail body 1. The vertical socket 12 can cooperate with the 7-shaped plug-in 11, and the positions of the 7-shaped plug-in 11 and the vertical socket 12 can be interchanged.

[0018] During use, the warning message "Pay attention to safety during road construction" is pasted in the warning area in front of the warning board 4 with a red tape. The warning board 4 is aligned with the vertical rod 3, and the warning board 4 is moved up and down to the required height, and the C-shaped snap ring 41 at the back of the warning board 4 is snap-fitted onto the vertical rod 3, and the C-shaped snap ring 41 presses the elastic layer 42 onto the vertical rod 3. Take four weighted bases 5, and paste a rubber anti-slip layer 51 on the bottom surface of each weighted base 5. There is a support foot at the bottom of the left and right ends of each road construction safety guardrail, and there is a threaded hole at the front and back bottom ends of each support foot. Install a weighted base 5 in each threaded hole, that is, rotate the threaded post 53 of the weighted base 5 clockwise and screw it into the threaded hole. The weighted base 5 increases the weight of the support foot, lowers the center of gravity of the road construction safety guardrail, makes the installation more stable, is not easily blown down, and is convenient for disassembly and assembly, and is flexible to use; moreover, the anti-slip protrusions 52 of the rubber anti-slip layer 51 can play a role in anti-slip and wear reduction. Adjacent road construction safety guardrails are plugged and matched through the 7-shaped plug-in 11 and the socket 12.

[0019] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
