[0034] As mentioned in the background technology, commercially available engineering blasting warning signs cannot be adjusted in length and cannot be disassembled, making them inconvenient to store and carry.

[0035] To solve this technical problem, this utility model provides a warning device that is used for warning and reminder in blasting projects.

[0036] For details, please refer to Figure 1 - Figure 5 The warning device specifically includes:

[0037] The support base 1 has a fixed vertical plate 2 vertically connected to its upper end. A warning piece 3 is provided at the front end of the fixed vertical plate 2. A fixed slide block 4 is vertically slidably connected to the inner side of the fixed vertical plate 2. The warning piece 3 and the fixed slide block 4 are detachably connected by Velcro.

[0038] The support base 1 has a slot 5, and a reinforcing plate 6 is fixedly connected to the bottom inner side of the slot 5. The lower end of the fixed vertical plate 2 is inserted into the slot 5. The lower end of the fixed vertical plate 2 has a connecting groove 7, and the connecting groove 7 is inserted into the reinforcing plate 6.

[0039] The fixed vertical plate 2 has a sliding groove 10 inside. The fixed slide 4 is vertically slidably connected to the fixed vertical plate 2 through the sliding groove 10. An extension vertical plate 8 is provided at the rear end of the fixed vertical plate 2. The top of the fixed vertical plate 2 and the top of the extension vertical plate 8 are rotatably connected through a connector 9. The inner side of the extension vertical plate 8 also has a sliding groove 10. The fixed slide 4 on the inner side of the fixed vertical plate 2 can slide to the inner side of the extension vertical plate 8 through the sliding groove 10.

[0040] The warning device provided by this utility model, through the structural design of the supporting base 1, the fixed vertical plate 2, the warning component 3, and the fixed slide 4, allows the device to be disassembled for transportation and is easy to assemble. It can also be adaptively adjusted according to the horizontal length, vertical length, and number of warning components 3, so that the device can be set at any position with different widths and heights, effectively improving the applicability of the device. Moreover, the overall structure of the device is simple and easy to manufacture, and it is convenient and quick to operate.

[0041] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0042] Example 1:

[0043] Please refer to Figure 1 - Figure 5 A warning device comprising:

[0044] The support base 1 has a fixed vertical plate 2 vertically connected to its upper end. A warning element 3 is provided at the front end of the fixed vertical plate 2. A fixed slide 4 is vertically slidably connected to the inner side of the fixed vertical plate 2. The warning element 3 and the fixed slide 4 are detachably connected by Velcro. Both ends of the fixed slide 4 are provided with anti-slip pads, so that the fixed slide 4 is limited by the anti-slip pads after each slide.

[0045] The support base 1 has a slot 5, and a reinforcing plate 6 is fixedly connected to the bottom inner side of the slot 5. The lower end of the fixed vertical plate 2 is inserted into the slot 5. The lower end of the fixed vertical plate 2 has a connecting groove 7, and the connecting groove 7 is inserted into the reinforcing plate 6.

[0046] The fixed vertical plate 2 has a sliding groove 10 inside. The fixed slide 4 is vertically slidably connected to the fixed vertical plate 2 through the sliding groove 10. An extension vertical plate 8 is provided at the rear end of the fixed vertical plate 2. The top of the fixed vertical plate 2 and the top of the extension vertical plate 8 are rotatably connected through a connector 9. The inner side of the extension vertical plate 8 also has a sliding groove 10. The fixed slide 4 on the inner side of the fixed vertical plate 2 can slide to the inner side of the extension vertical plate 8 through the sliding groove 10.

[0047] It can be seen that, during use, after placing the support base 1 in a suitable position, a suitable number of fixed vertical plates 2 are inserted into the upper end of the support base 1, and a suitable number of fixed slides 4 are placed inside the fixed vertical plates 2 as needed. After fixing the warning piece 3 to the fixed slides 4 with Velcro, the installation of the device is completed. In order to raise the height of the warning piece 3, the extension vertical plate 8 at the rear end of the fixed vertical plate 2 can be flipped upward through the connector 9, so that the extension vertical plate 8 is flipped 180°, so that the extension vertical plate 8 is perpendicular to the fixed vertical plate 2. This allows the fixed slides 4 to slide into the groove 10 opened in the extension vertical plate 8 through the groove 10 opened in the fixed vertical plate 2, thereby raising the height of the fixed slides 4 and thus raising the height of the warning piece 3.

[0048] Furthermore, in order to fix the extension vertical plate 8 after it is flipped, a limiting protrusion 11 is fixedly connected to the top of the fixed vertical plate 2, and a limiting groove 12 is opened on the top of the extension vertical plate 8. The extension vertical plate 8 is connected to the limiting protrusion 11 of the fixed vertical plate 2 through the limiting groove 12. In order to improve the stability of the connection between the fixed vertical plate 2 and the extension vertical plate 8, both the limiting protrusion 11 and the limiting groove 15 are U-shaped. Rotating pins 13 are fixedly connected to the top of both sides of the fixed vertical plate 2, and limiting pins 14 are fixedly connected to the bottom of both sides of the extension vertical plate 8. One end of the extension vertical plate 8 is rotatably connected to the rotating pin 13, and the other end of the connector 9 is opened with a limiting groove 15. The limiting pin 14 is located inside the limiting groove 15, and both ends of the limiting pin 14 and the limiting groove 15 are fastened together.

[0049] It is known that when the height of the warning piece 3 needs to be raised, the extension vertical plate 8 drives the connecting piece 9 to rotate upward around the pivot pin 13 until the extension vertical plate 8 is perpendicular to the fixed vertical plate 2. At this time, the extension vertical plate 8 is moved downward, and the limiting protrusion 11 is inserted into the limiting groove 12. At the same time, the limiting pin 14 is dislodged from one end of the limiting buckle groove 15 and enters the other end of the limiting buckle groove 15 to complete the buckling. Thus, the vertical movement of the extension vertical plate 8 is limited by the cooperation of the connecting piece 9 and the limiting pin 14. The horizontal movement of the extension vertical plate 8 is limited by the cooperation of the limiting protrusion 11 and the limiting groove 12. Thus, the fixed effect of the extension vertical plate 8 after being rotated is achieved through multi-directional limiting.

[0050] Example 2:

[0051] The warning device provided in Embodiment 1 is further optimized. Specifically, to facilitate the movement of the support base 1, the support base 1 is hollow inside and contains counterweight filler. The counterweight filler can be any of sand, stone, or liquid. Before movement, the support base 1 is not filled with any counterweight filler, making it relatively lightweight. After the support base 1 is placed in a suitable position, counterweight filler is added, increasing its weight and preventing it from easily tipping over after the fixed vertical plate 2 is inserted.

[0052] Example 3:

[0053] The warning device provided in Example 1 has been further optimized, specifically, as follows: Figure 6 As shown:

[0054] When it is necessary to fix a warning piece 3 with a long vertical dimension, multiple fixing slides 4 can be set inside a single fixing vertical plate 2. The multiple fixing slides 4 can be inserted into the inside of the fixing vertical plate 2 through the top of the slide groove 10 opened in the fixing vertical plate 2. The number of fixing slides 4 can be adjusted according to the height of the warning piece 3 and the fixing effect. By setting multiple fixing slides 4 inside a single fixing vertical plate 2, the warning piece 3 with a long vertical dimension can be fixed more firmly. Alternatively, the extension vertical plate 8 can be unfolded, and some of the fixing slides 4 inside the fixing vertical plate 2 can be slid into the extension vertical plate 8, thereby fixing the warning piece 3 with an even longer vertical dimension.

[0055] Example 4:

[0056] The warning device provided in Example 1 has been further optimized, specifically, as follows: Figure 7 As shown:

[0057] When it is necessary to fix the warning piece 3 with a long horizontal dimension, two or more fixing vertical plates 2 can be used. Each fixing vertical plate 2 has a support base 1 inserted at its lower end for support. The two fixing vertical plates 2 at the ends are placed in the corresponding positions of the two ends of the warning piece 3, so that the two ends of the warning piece 3 can be fixed by the two fixing vertical plates 2 at the ends. The extra fixing vertical plates 2 can be used to assist in fixing the middle of the warning piece 3. By unfolding the extension vertical plate 8 and cooperating with the height position adjustment fixing slide 4, the height position of the warning piece 3 can be adjusted.

[0058] Example 5:

[0059] The warning device provided in Example 1 has been further optimized, specifically, as follows: Figure 8 As shown:

[0060] When it is necessary to fix a large number of warning pieces 3 with a long horizontal dimension, two or more fixing vertical plates 2 can be used. Each fixing vertical plate 2 has a support base 1 inserted at its lower end for support. The number of fixing slides 4 inside the two fixing vertical plates 2 at the ends should be the same as the number of warning pieces 3. The two fixing vertical plates 2 at the ends are placed in positions corresponding to the two ends of the warning pieces 3, so that the two ends of the warning pieces 3 can be fixed by the two fixing vertical plates 2 at the ends. The extra fixing vertical plates 2 can be used to fix the middle part of the warning pieces 3. By unfolding the extension vertical plate 8 and cooperating with adjusting the height of the fixing slides 4, the height of the warning pieces 3 can be adjusted.

[0061] Example 6:

[0062] The warning device provided in Example 1 has been further optimized, specifically, as follows: Figure 9 As shown:

[0063] When it is necessary to fix a warning piece 3 that is slightly longer in the horizontal dimension and longer in the vertical dimension, multiple fixing vertical plates 2 can be set on a single support base 1. Each fixing vertical plate 2 has at least two fixing slides 4 inside. The upper and lower ends of both sides of the warning piece 3 can be fixed by the two fixing slides 4 inside each fixing vertical plate 2. The middle position of both sides of the warning piece 3 can be fixed by increasing the number of fixing slides 4 inside each fixing vertical plate 2. Alternatively, by unfolding the extension vertical plate 8, some of the fixing slides 4 inside the fixing vertical plate 2 can be slid into the extension vertical plate 8, thereby fixing a warning piece 3 that is longer in the vertical dimension.

[0064] Example 7:

[0065] The warning device provided in Example 1 has been further optimized, specifically, as follows: Figure 10 As shown:

[0066] When it is necessary to fix the warning piece 3 which is longer in the horizontal dimension and slightly longer in the vertical dimension, two or more fixing vertical plates 2 can be used. Each fixing vertical plate 2 has a support base 1 inserted at its lower end for support. At least two fixing slides 4 are provided inside the two fixing vertical plates 2 at the ends. Thus, the upper and lower ends of both sides of the warning piece 3 can be fixed by the two fixing slides 4 inside each fixing vertical plate 2. The middle position of both sides of the warning piece 3 can be fixed by increasing the number of fixing slides 4 inside each fixing vertical plate 2. Alternatively, by unfolding the extension vertical plate 8, some of the fixing slides 4 inside the fixing vertical plate 2 can be slid into the extension vertical plate 8, thereby fixing the warning piece 3 which is longer in the vertical dimension.
