Specific embodiments

[0021] 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 of 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.

[0022] Please refer to Figures 1-4 , the present utility model provides a safety warning device for construction projects, including a first support rod 1 and a second support rod 2. The bottom end of the first support rod 1 is fixedly connected with an installation assembly, and the top end of the second support rod 2 is fixedly installed with an installation shell 3 for pasting warning slogans. The installation assembly includes an installation plate 17 fixedly installed at the bottom end of the first support rod 1. Installation holes 18 are opened at the four corners of the top of the installation plate 17. The safety warning device in this embodiment is installed and fixed through the installation assembly. During installation, the user can install and fix the installation plate 17 at the installation position by passing a fixing structure such as an anchor rod through the installation holes 18, thereby installing and fixing the overall use position of the device.

[0023] Preferably, a hinge assembly is provided between the top end of the first support rod 1 and the bottom end of the second support rod 2. The first support rod 1 and the second support rod 2 are movably connected through the hinge assembly. The hinge assembly includes a fixed groove 5 opened at the top of the first support rod 1. An inner cavity of the fixed groove 5 is fixedly installed with a hinge shaft 6. The bottom end of the second support rod 2 is fixedly installed with a hinge seat 7. A hinge hole 8 is opened on the surface of the hinge seat 7. The inner wall of the hinge hole 8 is rotationally connected with the surface of the hinge shaft 6. A limiting plate 9 is fixedly installed on one side of the first support rod 1 and corresponding to the fixed groove 5. One side of the hinge seat 7 is attached to the surface of the limiting plate 9.

[0024] In this embodiment, the first support rod 1 and the second support rod 2 are installed in a movable connection manner. In this way, when it is necessary to replace the warning slogan in the installation shell 3, the second support rod 2 can be rotated to lower the height of the installation shell 3, so as to facilitate the user to replace the warning slogan in the installation shell 3. Through the setting of the limit plate 9, the use angle of the second support rod 2 can be limited, so that it is in the coaxial position with the first support rod 1 during use.

[0025] Among them, a positioning component for positioning the second support rod 2 is further installed on the front surface of the first support rod 1. The positioning component includes a positioning tube 10 fixedly installed on the front surface of the first support rod 1. A positioning rod 11 is threadedly connected to the front surface of the positioning tube 10. One end of the positioning rod 11 sequentially penetrates through the positioning tube 10 and the first support rod 1 and extends to the inner cavity of the fixing groove 5 to fit with the surface of the hinge seat 7.

[0026] Through the setting of the positioning component, after the warning slogan in the installation shell 3 is replaced, the user can reversely rotate the second support rod 2 to make the second support rod 2 in the coaxial position with the first support rod 1. Then the user can tighten the positioning rod 11 to lock and fix the use position of the second support rod 2.

[0027] It is worth noting that a cover plate 4 is detachably installed at the bottom of the installation shell 3. The cover plate 4 includes an installation frame 12. A transparent acrylic plate 13 is fixedly installed in the inner cavity of the installation frame 12. A through groove 14 adapted to the installation frame 12 is opened at the bottom of the installation shell 3. The surface of the installation frame 12 is slidably connected to the inner wall of the through groove 14. A locking component is arranged at the bottom of the cover plate 4. The cover plate 4 is locked and fixed in the inner cavity of the installation shell 3 through the locking component. The locking component includes a locking plate 15 fixedly installed at the bottom of the installation frame 12. A locking rod 16 is threadedly connected to the bottom of the locking plate 15. The top end of the locking rod 16 penetrates through the locking plate 15 and extends above the locking plate 15 to be threadedly connected to the bottom of the installation shell 3.

[0028] Through the setting of the cover plate 4, after the warning slogan is pasted in the inner cavity of the installation shell 3, the user can insert the cover plate 4 into the inner cavity of the installation shell 3 through the through groove 14 to play a protective role for the warning slogan. Through the setting of the locking component, after the cover plate 4 is installed in the inner cavity of the installation shell 3, the user can tighten the locking rod 16 to lock and fix the cover plate 4 in the inner cavity of the installation shell 3. In this embodiment, the main body of the cover plate 4 is composed of a transparent acrylic plate 13, which can play a protective role for the warning slogan and at the same time facilitate pedestrians to see the warning content.

[0029] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
