Description

Technical Field

[0001] This utility model relates to the field of construction safety technology, and in particular to a warning device for construction site problems. Background Technology

[0002] Nowadays, construction warning devices are used in various construction sites, through display boards, to remind workers to pay attention to the safety of the surrounding environment, prevent accidents, and protect the lives and health of construction workers.

[0003] Currently, the only method of fixing warning devices on construction sites is to use expansion bolts to ensure the stability of the device. By anchoring the warning sign to the ground with expansion bolts, the warning sign can be tightly connected to the ground and can withstand greater tension and wind force. It is not easy for it to shake, tip over or be easily moved. It is especially suitable for use in open construction sites with strong winds and in scenarios where warning signs need to be fixed for a long time.

[0004] While expansion bolts ensure the stability of the device, installation requires specialized tools such as electric drills, demanding a certain level of skill from the operator. Improper operation can lead to insecure installation of the ground nails or expansion bolts, affecting the fixing effect. During removal, if the expansion bolts are rusty or overtightened, they will be difficult to remove, and forced removal can further damage the ground. Furthermore, the remaining parts after removal require special treatment, increasing the cleanup workload after construction. At construction sites, we often see warning signs fixed with expansion bolts. From a material perspective, metal warning signs are hard and difficult to bend; forced folding can cause the material to break, damaging the warning patterns and text, rendering it meaningless. While plastic has some flexibility, its thickness is sufficient to ensure strength, preventing folding. Therefore, a construction site warning device is proposed to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a construction site problem warning device, which aims to improve the problem that the warning device screen cannot be cleared at any time and cannot be carried around in the prior art.

[0019] As a further description of the above technical solution:

[0020] The bottom of the warning sign has a groove, and the sliding plate is slidably connected inside the groove.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by pulling the pull rod outward, the restriction on the outer shell is removed, and the outer shell is slid to the end of the support rod, so that the connecting rod rotates on the support rod.

[0031] 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.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5This utility model provides an embodiment of a construction site problem warning device, including a warning sign 1. A support rod 11 is rotatably connected to the outer side of the warning sign 1, and a connecting rod 10 is also rotatably connected to the outer side of the warning sign 1. The tilt angle of the warning sign 1 can be adjusted by changing the included angle between the connecting rod 10 and the support rod 11, thereby adapting to different display needs. A housing 9 is slidably connected to the outer side of the support rod 11. The rotation angle of the connecting rod 10 is determined by changing the position of the housing 9. A baffle 16 is fixedly connected to the outer side of the housing 9. The other end of the connecting rod 10 is rotatably connected to the middle of the baffle 16. A buckle assembly is installed on the outer side of the housing 9, which can restrict the position of the housing 9, thereby stabilizing the included angle of the connecting rod 10. The buckle assembly includes a housing 12, which is fixedly connected to the outer side of the housing 9. A pull rod 21 is slidably connected to the middle of the housing 12. A spring 14 is sleeved on the outer side of the pull rod 21, and a retaining ring 15 is fixedly connected to the outer side of the pull rod 21. A slot 20 is formed on the outer side of the support rod 11. When placing the warning device, simply pull the lever 21 outward to disengage it from the slot 20. At this time, the outer casing 9 can slide freely on the support rod 11, allowing the connecting rod 10 to rotate. Once the connecting rod 10 has rotated to the desired angle, release the lever 21. Then, through the cooperation of the retaining ring 15 and the spring 14, the lever 21 can be re-engaged with the slot 20. This allows the warning device to be folded up for easy carrying.

[0033] A pull ring 13 is rotatably connected to the outer side of the pull rod 21, allowing for easy pulling of the pull rod 21. A retaining ring 15 is used to limit the position of the pull rod 21 and prevent it from detaching from the housing 12.

[0034] Reference Figure 1 , Figure 3 and Figure 4 A sliding plate 5 is slidably connected to the outer side of the warning sign 1. A spring 18 and a telescopic rod 19 are fixedly connected to the middle of the sliding plate 5. A scraper 17 is fixedly connected to the other end of the spring 18 and the telescopic rod 19. When the warning sign 1 is affected by dust, pulling the handle 6 causes the sliding plate 5 to slide in front of the warning sign 1. At this time, the spring 18 and the telescopic rod 19 push the scraper 17 toward the image of the warning sign 1, ensuring that the scraper 17 makes full contact with the image of the warning sign 1. As the sliding plate 5 moves, it ensures that the image of the warning sign 1 is cleaned, making it easier to display the warning content.

[0035] The bottom of the warning sign 1 has a groove 8, and the slide plate 5 is slidably connected inside the groove 8. By providing the groove 8, the groove 8 can restrict the horizontal movement of the slide plate 5.

[0036] Reference Figure 1 and Figure 3The warning sign 1 has a fixed obstruction block 2 at its top, a warning light 4 at its bottom, and a handle 3 at its top. The obstruction block 2 is used to shield the warning light 4 and the warning sign 1, providing protection. The warning light 4 illuminates the warning sign 1, providing illumination at night to alert staff and those nearby. The warning sign 1 is equipped with casters 7 at its bottom, allowing for easy transport and handling after folding.

[0037] Working principle: Place the warning device at the target location, then pull the handle 3 and pull the ring 13 outwards. At this time, the ring 13 drives the pull rod 21 to move outwards and disengage from the slot 20. The outer shell 9 can then slide freely on the outside of the support rod 11, causing the connecting rod 10 to rotate, thus unfolding and retracting the warning sign 1. When retracting, pull the rod 21 out and move the outer shell 9. At this time, the connecting rod 10 and the support rod 11 rotate relative to each other. When the connecting rod 10 is parallel to the support rod 11, release the pull rod 21. Then, under the action of the spring 14 and the retaining ring 15, the pull rod 21 re-engages with the slot 20, completing the folding and retraction of the warning device.

[0038] By pulling handle 6, the slide plate 5 slides inside the groove 8. Under the action of spring 18 and telescopic rod 19, scraper 17 adheres tightly to the image of warning sign 1. Then, in conjunction with the movement of slide plate 5, the image of warning sign 1 is cleared of dust, making the image of warning sign 1 clear. At night, warning light 4 illuminates the image of warning sign 1 to provide nighttime warning function.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
