Description

Technical Field

[0001] The utility model relates to the field of engineering construction, and specifically refers to a construction warning sign for engineering construction. Background Art

[0002] A construction warning sign is a visual reminder tool and plays a very important role in engineering construction. By using construction warning signs, workers and pedestrians at the construction site can be effectively reminded and warned to pay attention to safety, preventing accidents. Therefore, the correct use and maintenance of construction warning signs are very important.

[0003] The Chinese utility model patent with the publication number CN219315544U discloses a municipal construction warning sign, including a base, a warning sign assembly installed on the upper surface of the base, and further including two shells. The two shells are respectively connected to the warning sign assembly. A pressing block is slidably installed inside the shell, and the upper end of the pressing block extends out of the upper wall of the shell. A cavity is provided inside the pressing block, a first spring is provided inside the cavity, the first spring is connected to a plug rod, a round hole with a diameter larger than the cross-sectional diameter of the plug rod is provided on the side wall of the shell, a connecting rod is connected to the lower surface of the pressing block, a traveling wheel is installed at the lower end of the connecting rod, a second spring is connected to the lower surface of the pressing block, and the end of the second spring away from the pressing block is connected to the bottom wall of the shell.

[0004] This prior art solves the problem that the existing municipal construction warning signs are inconvenient to move. There is no need for manual handling, and only need to drag the municipal construction warning sign to move. However, this prior art still has room for improvement:

[0005] 1. The construction warning signs designed by the existing technology cannot replace the warning content on them, which leads to the need to prepare multiple devices in case of different warning situations. On the one hand, this undoubtedly increases the cost of purchasing and managing these devices. At the same time, storing multiple warning signs also means a greater storage space requirement, further increasing the additional cost. On the other hand, at the construction site, the warning situation may change at any time. If the content on the warning sign cannot be updated in time, it may not accurately reflect the actual situation, thus increasing the safety hazards at the construction site.

[0006] 2. The construction warning signs designed by the existing technology lack the corresponding shock absorption function. Therefore, when being towed, there will be vibration friction with the ground, and these vibrations are transmitted to the transfer personnel through the equipment. After a long time, it may cause the transfer personnel's arms to become numb due to vibration, thereby increasing their physical burden.

[0007] In view of this, it is necessary to improve the above defects. Summary of the Utility Model

Detailed Description of the Specific Embodiment

[0024] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1 to 6 shown, the present utility model provides a construction warning sign for engineering construction. The warning sign includes a bottom plate 1, which serves as the base of the entire device and bears the supporting role. The front part of the top end of the bottom plate 1 is rotatably connected to a rotating frame 2. A receiving groove 3 is formed on the top surface of the rotating frame 2. A warning sign board 4 is slidably connected in the receiving groove 3, and the rotating frame 2 and the warning sign board 4 are connected by a buckle structure 5. There are multiple warning sign boards 4, and corresponding warning contents can be customized according to different engineering working conditions. Through the buckle structure 5, it can be quickly replaced. In this way, when different warning scenarios are required, there is no need to prepare multiple devices, which reduces costs and is also convenient to carry.

[0027] At the same time, the middle part of the rear end of the rotating frame 2 is rotatably connected to a support plate 6. A number of uniformly distributed convex ribs 7 are formed on the top end of the bottom plate 1. The support plate 6 abuts between the front and rear two convex ribs 7. Through the support of the convex ribs 7 on the support plate 6, the rotating frame 2 and its components can adjust the angle by adjusting the abutment with different convex ribs 7. There are a number of grooves 8 on the support plate 6, and the distances, shapes, sizes, etc. between the grooves 8 and the convex ribs 7 are all adapted. Therefore, when the rotating frame 2 is completely laid down, the convex ribs 7 can be inserted into the grooves 8 to save the area after folding.

[0028] Then, walking wheels 9 are arranged on both sides of the front part below the bottom plate 1. The walking wheels 9 and the bottom plate 1 are connected to each other through a shock absorption structure 10. Threaded cylinders 11 are fixedly connected to both sides of the rear part of the bottom end of the bottom plate 1. A threaded rod 12 is threadedly connected in the threaded cylinder 11. The bottom end of the threaded rod 12 is fixedly connected to a bottom foot 13. During use, by rotating the threaded rod 12 and the bottom foot 13, its length can be adjusted relative to the threaded cylinder 11, so as to achieve fine adjustment in height to meet the requirements of different scenarios. Finally, a handle 14 is fixedly connected to the middle part of the rear end of the bottom plate 1. During use, by pulling the handle 14, the rear part of the device can be lifted, so that the two front walking wheels 9 are on the ground, which is convenient for transportation.

[0029] In order to further explain the specific working principle of the present utility model, the above-mentioned buckle structure 5 includes cavities two 15 opened at the top ends on both sides of the warning sign board 4. A fixing rod 16 is fixedly connected inside the cavities two 15. A movable block 17 is slidably connected to the fixing rod 16. A pressing rod 18 and a bolt 19 are respectively fixedly connected to the top end and the bottom end of the movable block 17. Both the bolt 19 and the pressing rod 18 pass through the cavities two 15 and extend to the outside of the warning sign board 4. The orientations of the bolts 19 on both sides are opposite. Slots 20 for cooperating with the bolts 19 are opened on the rotating frame 2. Spring two 21 is fixedly connected to the adjacent sides of the bolts 19 on both sides. Spring two 21 is fixedly connected to the side wall of the cavities two 15.

[0030] During use, the fixing of the warning sign board 4 and the rotating frame 2 is realized by inserting the bolt 19 into the inside of the slot 20. When it is necessary to cancel the fixing, the user only needs to pinch the pressing rod 18, which can drive the movable block 17 to slide on the fixing rod 16, and then drive the bolt 19 to squeeze the spring two 21 and disengage from the slot 20. When it completely disengages from the slot 20 and retracts into the inside of the cavities two 15, the rotating frame 2 and the warning sign board 4 are released from the limit. At this time, the user can replace them.

[0031] In order to further explain the specific working principle of the present utility model, the above-mentioned shock absorption structure 10 includes a buffer seat 22 fixedly connected to the bottom end of the bottom plate 1. A cavity one 23 with a downward through opening is opened inside the buffer seat 22. A buffer block 24 is arranged inside the cavity one 23. Sliders 25 are fixedly connected to the front and rear ends of the buffer block 24. A sliding column 26 is slidably connected inside the slider 25. The sliding column 26 is fixedly connected to the front and rear walls of the cavity one 23. A wheel frame 27 is fixedly connected to the bottom end of the buffer block 24. The wheel frame 27 is rotatably connected to the traveling wheel 9. Dampers 28 are fixedly connected to the front and rear parts of the top end of the buffer block 24. The top ends of the dampers 28 are fixedly connected to the top wall of the cavity one 23. A spring one 29 is sleeved outside the damper 28. The top end and the bottom end of the spring one 29 are respectively fixedly connected to the top wall of the cavity one 23 and the top end of the buffer block 24.

[0032] Thus, when the device collides during the transfer process, it will impact the traveling wheel 9, causing it to change its position in the horizontal direction. At this time, the impact force will be transmitted to the buffer block 24 through the traveling wheel 9, causing the slider 25 to slide on the sliding column 26, driving its movement and causing the spring one 29 and the damper 28 to contract at the same time. At the same time, the contraction of the spring one 29 and the damper 28 will generate a deformation force, and this part of the deformation force will offset and absorb a certain degree of the above-mentioned impact force. This process repeats, and finally a dynamic balance can be achieved to realize the effect of shock absorption and buffering.

[0033] The above description is about the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design, without creative efforts, structural manners and embodiments similar to the technical solution without departing from the gist of the creation of the present utility model, they shall fall within the protection scope of the present utility model.
