[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figure 1-3 This embodiment provides a warning barrier for construction sites, including a telescopic frame 1. One end of the telescopic frame 1 is connected to a first support base 2, and the other end is connected to a second support base 4. Both the first support base 2 and the second support base 4 are rotatably connected to the telescopic frame 1. When the first support base 2 and the second support base 4 are simultaneously pressed towards the telescopic frame 1, the telescopic frame 1 will fold together as a whole. A locking block 21 is symmetrically installed on the top and bottom of one side of the first support base 2. A U-shaped locking groove is opened on the outer side of each locking block 21. An automatic reel is installed on the other side of the first support base 2. 3. During use, the construction site warning barrier is supported by the first support base 2 and the second support base 3, and the telescopic frame 1 is installed between the first support base 2 and the second support base 4. When in use, the first support base 2 and the second support base 4 can be pulled to the sides to open the warning barrier, so the installation is very convenient. In addition, when folding it up, the first support base 2 and the second support base 4 only need to be pressed towards the telescopic frame 1 to fold the telescopic frame 1 together, thus completing the overall folding of the warning barrier. This makes it convenient and quick to store, and the space occupied after storage is small, making it easy to handle and transport.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a warning reflective cloth 31 is wound inside the automatic winding drum 3 and extends out from one side outlet of the automatic winding drum 3. A pull rod 32 is fixedly connected to one end of the warning reflective cloth 31 extending out of the automatic winding drum 3. When the warning reflective cloth 31 is pulled outward, it can extend outward. When released, the warning reflective cloth 31 automatically retracts into the automatic winding drum 3. Therefore, the warning reflective cloth 31 will automatically wind up inside the automatic winding drum 3 without external force, making it convenient to store.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, limit plates 41 are symmetrically installed on the top and bottom of both sides of the second support base 4. A cloth winding roller 42 is connected between the inner sides of the two limit plates 41 on the same side of the second support base 4. The length of the cloth winding roller 42 is the same as the width of the warning reflective cloth 31. One end of the warning reflective cloth 31 passes around the outside of the second support base 4 and passes through the inner side of the limit plates 41 on both sides of the second support base 4 in sequence, and is attached to the cloth winding roller 42. Because the warning reflective cloth 31 passes around the inner side of the limit plates 41, the warning reflective cloth 31 is more regular after it is unfolded.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the size of the pull rod 32 matches the size of the U-shaped groove on the locking block 21. After one end of the warning reflective cloth 31 is pulled into the inner side of the two locking blocks 21, the pull rod 32 is locked into the U-shaped groove on the locking block 21, thereby fixing the warning reflective cloth 31 in place and preventing it from being retracted. At the same time, if you want to remove the warning reflective cloth 31, you only need to remove the pull rod 32 from the U-shaped groove on the locking block 21.

[0027] Working principle: During use, the warning barrier at the construction site is supported by the first support base 2 and the second support base 3. Pulling the first support base 2 and the second support base 4 to both sides will open the warning barrier. At this time, one end of the warning reflective cloth 31 is pulled out from the automatic reel 3, passes around the inside of the two pairs of limiting plates 41 on the second support base 4, and then the pull rod 32 is inserted into the U-shaped groove of the locking block 21 on the first support base 2, thereby fixing the warning reflective cloth 31 in place. To remove the warning reflective cloth 31, simply remove the pull rod 32 from the U-shaped groove on the locking block 21, and then slowly release the warning reflective cloth 31 so that it automatically retracts into the automatic reel 3. At this time, pressing the first support base 2 and the second support base 4 towards the telescopic frame 1 will fold the telescopic frame 1 together, completing the overall folding of the warning barrier. This makes it convenient and quick to store, and the space occupied after storage is small, making it easy to handle and transport.

[0028] All technical features in this embodiment can be freely combined according to actual needs.

[0029] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
