[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides a warning net for road construction through improvement. Please refer to Figures 1-4 , including: a bottom plate 1, with support rods 2 inserted on the outer wall of the bottom plate 1. The support rods 2 are symmetrically arranged about the central axis position of the bottom plate 1. An external thread 3 is provided in a ring shape at the connection between the support rod 2 and the bottom plate 1, and the support rod 2 is threadedly connected to the bottom plate 1 through the external thread 3. A card slot 4 is opened on the outer wall of the upper end of the support rod 2. A circular support plate 5 is sleeved on the outer wall of the support rod 2. A jack 6 is opened on the outer wall of the support plate 5. The support plate 5 forms a detachable structure with the support rod 2 through the jack 6, and the support rod 2 is threadedly connected to the support plate 5 through the external thread 3 and the jack 6. One end of the support rod 2 is threadedly connected to the support plate 5 through the external thread 3 and the jack 6, and the rod diameter of the other end is smaller, facilitating the support plate 5 to be sleeved on the support rod 2 through the jack 6; a warning net body 7 is wound around the outer wall of the middle part of the support rod 2. A retaining net 8 made of plastic material is arranged in the middle of the warning net body 7. A connecting piece 9 is arranged at the connection of the retaining net 8, and the connecting piece 9 is snap-connected to the support rod 2 through the card slot 4. The retaining net 8 and the connecting piece 9 are evenly distributed at equal intervals along the outer wall of the warning net body 7. The connecting piece 9 is used to fix the warning net body 7 through the support rod 2 and the support plate 5, enabling it to be stably placed around the construction site; connection holes 10 are opened on the outer walls of both ends of the connecting piece 9. A through hole 11 is opened at the connection between the support rod 2 and the connection hole 10, and the warning net body 7 is threadedly connected to the support rod 2 through the connecting piece 9, the connection hole 10, and the through hole 11. The provided warning net body 7 can be conveniently connected to the combination of the support rod 2 and the support plate 5 through the connecting piece 9 and the card slot 4 on the support rod 2. After the support rod 2 and the support plate 5 are retracted, they form a cylindrical structure through nesting, facilitating the winding and arrangement of the warning net body 7. After retraction, it occupies less space, and after expansion, it has a larger surrounding range and is convenient to use.

[0022] Please refer to Figure 1 and Figure 4 , a warning net for road construction, including: warning marks 12 are coated on the outer wall of the middle part of the connecting piece 9. The warning marks 12 are evenly distributed at equal intervals along the outer wall of the connecting piece 9. A reflective strip 13 is adhered to the outer wall of the connecting piece 9 close to the warning marks 12, and the reflective strips 13 are symmetrically arranged about the central axis position of the warning marks 12. The provided warning marks 12 and reflective strips 13 are used to play a warning role, having an effect of persuading away approaching personnel under visible conditions, and through the reflective strips 13, they play a reminder role by reflecting light when vehicles approach at night.

[0023] Working principle: For this type of warning net used in road construction, first, the staff place the wound warning net beside the road construction site and unfold it in the set enclosure area. First, the staff open the warning net body 7 made of plastic from the wound state, pull the warning net body 7 off the outer wall of the support rod 2 or the support plate 5. The surface of the unfolded warning net body 7 is in an alternating state of the barrier net 8 and the connecting piece 9. Then, the staff remove the support plate 5 from the support rod 2. The rod diameter of the support rod 2 at the end far from the external thread 3 is slightly smaller, which is convenient for the removal and placement of the support plate 5 on the support rod 2. The removed support plate 5 is placed at the warning net node by the staff. Then, the staff pull out the support rod 2 from the bottom plate 1 and install it on the support plate 5 through the external thread 3 and the jack 6. Then, the staff insert the connecting piece 9 of the warning net body 7 into the slot 4 on the support rod 2 and use fasteners to fasten the connecting piece 9 through the connecting hole 10 and the through hole 11. Finally, the warning net body 7 is fixed by multiple points, so that the barrier net 8 can play a better warning and blocking effect, and the warning mark 12 coated on the connecting piece 9 and the reflective strip 13 adhered can both play a better effect of persuading people to leave. After the construction is completed, it is convenient to recycle and sort out the warning net body 7, the support plate 5 for stability and the support rod 2, which is beneficial for subsequent use.

[0024] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
