[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a construction site safety warning device, comprising:

[0025] The system consists of a base 1, a warning sign 2, and a folding mechanism 3. The warning sign 2 is installed on top of the folding mechanism 3, and the folding mechanism 3 is installed inside the base 1 for quick storage of the warning sign 2.

[0026] The folding mechanism 3 includes a support frame 31, a support rod 32, an extension rod 33, a rotating component 34, and an unfolding component 35. Two support frames 31 are arranged in parallel inside the base 1, and their bottoms are rotatably connected to the base 1 through the rotating component 34. The base 1 is provided with two support frames 31. An extension rod 33 is rotatably installed on one side of the support frame 31, and a support rod 32 is rotatably installed on the other side. A warning sign 2 is installed on the surface of the two extension rods 33. The unfolding component 35 is arranged between the two support frames 31 and is used to drive the support frames 31 to move horizontally to adjust the spacing.

[0027] Specifically, the folding mechanism 3 facilitates the storage and display of the warning sign 2, making it easy to store the safety warning device. After storage, it occupies little space, compressing the three-dimensional structure in the unfolded state into a flat shape, which is convenient for transportation and carrying. Furthermore, reflective warning signs are provided on both sides of the warning sign 2.

[0028] In the unfolded state, the support rod 32, the extension rod 33 and the warning sign 2 form a stable triangle. When folded, the overall height is ≤0.5 meters, which is convenient for transportation and enables quick switching between multiple scenarios.

[0029] The unfolding component 35 includes a connecting seat 351, a cross combination rod 352, and a sliding member 300. The two ends of the top of the cross combination rod 352 are hinged with connecting seats 351, and the two connecting seats 351 are respectively fixed to the surfaces of the two support frames 31. The two ends of the bottom of the cross combination rod 352 are provided with sliding members 300, and the two sliding members 300 are respectively located on the surfaces of the two support frames 31.

[0030] Furthermore, the unfolding component 35 is located between two support frames 31, one of which remains stationary while the other moves. During the movement, the cross-combination rod 352 deforms. The sliding component 300 prevents the cross-combination rod 352 from failing to deform, thus allowing the two support frames 31 to move away from each other. This works in conjunction with the warning sign 2. When stored, the distance between the two support frames 31 decreases, allowing them to fit into the base 1 and reducing space occupation.

[0031] The sliding component 300 includes a slide block 301 and a guide rail 302. The slide blocks 301 are rotatably mounted on both ends of the bottom of the cross combination rod 352. The surface of the support frame 31 is provided with a guide rail 302 for sliding the slide block 301 and preventing it from falling off.

[0032] It is worth noting that when the cross combination rod 352 deforms, the slide 301 hinged to one end of the bottom of the cross combination rod 352 can slide in the inner groove of the guide rail 302, and the slide 301 will not disengage from the inner groove of the guide rail 302.

[0033] The rotating component 34 includes a rod 341 and a sleeve 342. One end of the rod 341 is welded to the inner wall of the base 1. The surface of the rod 341 is movably sleeved with the sleeve 342. The rod 341 is fixed to the bottom of one of the support frames 31, and the sleeve 342 is fixed to the bottom of the other support frame 31. The rod 341 is a high-strength metal rod.

[0034] One end of the rod 341 is welded to the inner wall of the base 1. The sleeve 342 is slidably installed on the surface of the rod 341. The sleeve 342 can slide on the surface of the rod 341. The rod 341 is fixed to the bottom of the support frame 31. The sleeve 342 is fixed to the bottom of another support frame 31 to facilitate the movement of the support frame 31. As shown in the figure, a rectangular groove is provided on one side of the base 1 for the support frame 31 to extend. The surface of the rod 341 can be plated with a hard chrome layer (thickness ≥ 0.05 mm) to further improve wear resistance and realize the rotation adjustment of the two support frames 31.

[0035] Both extension rods 33 have slots 4 on their surfaces. The warning sign 2 has a block 5 that matches the slot 4. The end of the extension rod 33 is slidably fitted with a first bolt 6 that is threaded to the inner hole of the block 5. The base 1 has a mounting hole 7 on one side that is threaded to the two first bolts 6.

[0036] It is worth noting that the first bolt 6 slides at the end of the extension rod 33 and passes through the slot 4, allowing it to be bolted into the inner hole of the clip 5. The clip 5 is inserted into the slot 4, and the first bolt 6 is threaded into the inner hole of the clip 5 to fix the warning sign 2 to the ends of the two extension rods 33, while simultaneously limiting the distance between the two support frames 31. Furthermore, the base 1 has mounting holes 7 on one side that are threaded to the two first bolts 6. When the warning sign 2 is separated from the extension rod 33, the two first bolts 6 are freed up, allowing the warning sign 2 to be placed on the base 1. The base 1 has two mounting holes 7 on one side that are threaded to the two first bolts 6 respectively. When the warning sign 2 is placed on the base 1, the first bolt 6 passes through the clip 5 and is threaded into the mounting holes 7, thus fixing the warning sign 2 to the base 1 and completing the storage.

[0037] A support platform 9 is slidably installed on the bottom of the base 1 via a rectangular frame 8. A second bolt 10 is slidably installed inside the support platform 9. Both support rods 32 have slots 11 that are threadedly connected to the second bolt 10. The surface of the base 1 is provided with positioning holes 12 that are threadedly installed to the second bolt 10.

[0038] Specifically, the support platform 9 slides within the rectangular frame 8, which is fixed to the bottom of the base 1. The purpose of extending the support platform 9 is to correspond to the movable support frame 31. The lower end of the movable support rod 32 is located within the support platform 9, and a second bolt 10 is slidably installed within the support platform 9. This second thread is threaded into the slot 11 inside the support rod 32 to fix the support rod 32. Meanwhile, the bottom of the support rod 32 located within the base 1 abuts against the contact block at the bottom of the inner wall of the base 1. At the same time, the surface of the base 1 is provided with a positioning hole 12 for threaded installation of the second bolt 10. The purpose is to thread the second bolt 10 into the positioning hole 12 on the surface of the base 1 to prevent the support platform 9 from moving after the warning device is installed and stored.

[0039] An anti-disengagement bolt 13 is slidably installed inside the support frame 31 for threaded installation with the hole on the surface of the extension rod 33, thereby limiting the position of the extension rod 33;

[0040] The anti-loosening bolts 13 on the surface of the rotating support frame 31 are threaded into the holes on the surface of the extension rod 33 to fix the extension rod 33.

[0041] The bolts and bolt holes involved in this application are all galvanized and coated with an anti-stick coating to extend their service life. The bolts can be used even if there is a small amount of debris on their surface.

[0042] This device rotates the two support frames 31 out of the base 1, pulling one support frame 31 away from the other. At this time, the cross-shaped combination rod 352 deforms, causing the slide block 301 to slide within the groove. Adjusting the distance between the two support frames 31 ensures that the two locking blocks 5 at the bottom of the warning sign 2 can be inserted into the two locking slots 4 respectively. Rotating the two extension rods 33 out allows the two locking blocks 5 to be inserted into the two locking slots 4 respectively. The first bolt 6 passes through the end of the extension rod 33 and is threaded into the mounting hole 7 in the locking block 5, thus fixing the warning sign 2 to the ends of the two extension rods 33. Furthermore, rotating the anti-loosening bolt 13 on the surface of the support frame 31 and threading it into the hole on the surface of the extension rod 33 fixes the extension rod 33. Then, rotating the support rod 32 out, one support rod 32... One end abuts against the base 1, and the other support rod 32 is located at the support platform 9. The support rod 32 is fixed by the second bolt 10 in the support platform 9 and the threaded installation of the second bolt 10 in the slot 11 of the support rod 32. The support rod 32, the support frame 31 and the base 1 form a triangle to realize the installation and use of the warning sign 2. When storing, both the extension rod 33 and the support rod 32 are stored in the support frame 31, and the support frame 31 is rotated and folded into the base 1. When the warning sign 2 is separated from the extension rod 33, the two first bolts 6 are freed up, and the warning sign 2 is covered on the base 1. The base 1 has two mounting holes 7 on one side, which are threaded to the two first bolts 6 respectively. When the warning sign 2 is covered on the base 1, the first bolts 6 pass through the locking block 5 and are threaded to the mounting holes 7, so that the warning sign 2 is fixed on the base 1 and the storage is completed.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
