Description

Technical Field

[0001] This utility model is a hazard warning device for civil engineering safety, belonging to the field of civil engineering. Background Technology

[0002] Civil engineering construction sites are complex environments, involving multiple risk factors such as working at heights, heavy machinery, and temporary structures. Any negligence can lead to safety accidents. Warning lights, which emit warning light at night, are often installed in dangerous areas of construction sites to alert workers. The lower end of the hollow column in the warning light is threaded, and after passing through a through hole in the positioning seat, two clamping nuts on the hollow column restrict the relative position of the column and the positioning seat. The positioning seat is then bolted to a support. Because the support for installing warning lights on construction sites cannot be kept dry, the bolts restricting the positioning seat may become corroded and unable to be disassembled properly, or the clamping nuts may become impossible to tighten, affecting the later recycling and reuse of the warning light. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hazard warning device for civil engineering safety to solve the problems mentioned in the background technology. This utility model facilitates the complete recycling and reuse of the alarm light.

[0004] To achieve the above objectives, this utility model provides a hazard warning device for civil engineering safety, comprising:

[0005] The alarm light has an opening at its lower end;

[0006] A hollow column is inserted into the lower part of the alarm light at its upper end, and its relative position to the alarm light remains unchanged. The outer surface of the lower end of the hollow column is machined with external threads.

[0007] U-shaped plate, fitted onto the lower end of the hollow column;

[0008] Two clamping nuts are provided, both of which are threadedly connected to the lower end of the hollow column, and the U-shaped plate is disposed between the two clamping nuts;

[0009] The base plate is connected to the U-shaped plate via a connector, and two fixing holes are provided on the vertical part of the base plate.

[0010] Furthermore, the connector includes a first connecting ear, and both ends of the U-shaped plate are equipped with the first connecting ear. Two second connecting ears that mate with the first connecting ears are installed on the upper surface of the horizontal part of the base plate. The first connecting ear is connected to the second connecting ear by a fastener formed by a screw and a limiting nut.

[0011] Furthermore, a connecting plate is provided at the upper part of one end of the U-shaped plate near the bottom plate. An intermediate plate is installed at both ends of the connecting plate. The intermediate plate is inserted between the first connecting ear and the second connecting ear. One end of the screw passes through the second connecting ear, the intermediate plate and the first connecting ear and is threaded with a limit nut. A Z-shaped rod is installed in the middle of the connecting plate. A clamping plate is installed at the end of the Z-shaped rod away from the connecting plate. The clamping plate is slidably installed in the U-shaped plate. A semi-circular groove is machined on the side of the clamping plate facing the hollow column. The semi-circular groove and the space in the U-shaped plate away from the bottom plate form a circular channel for storing the hollow column.

[0012] Furthermore, a rectangular groove penetrating the first connecting ear is provided on one side, and a portion of the screw shank is located within the rectangular groove.

[0013] Furthermore, the first connecting ear and the U-shaped plate are integrally formed, and the second connecting ear and the base plate are integrally formed.

[0014] Furthermore, a pressure ring is provided on the upper side of the U-shaped plate, the pressure ring is sleeved on the hollow column, and a clamping nut is provided on the upper side of the pressure ring.

[0015] Furthermore, a rubber ring is provided between the pressure ring and the U-shaped plate, and the rubber ring is sleeved on the hollow column.

[0016] Furthermore, a sleeve is installed at the bottom of the alarm light, and the upper end of the hollow column is threaded into the sleeve.

[0017] The beneficial effects of this utility model are:

[0018] 1. The first connecting ear and the second connecting ear are connected by the structure formed by the screw and the limiting nut to complete the assembly of the U-shaped plate and the base plate. At this time, the U-shaped plate and the base plate together form a positioning seat to limit the relative position of the hollow column and the carrier. When the screw fixing the base plate cannot be disassembled normally due to rust, the U-shaped plate and the base plate can be separated. When the screw and the limiting nut cannot be separated, the screw can be cut off by using the space of the rectangular groove, which facilitates the complete recycling and reuse of the alarm light in the later stage.

[0019] 2. After the hollow column passes through the U-shaped plate, the semi-circular groove on the clamp plate contacts the surface of the hollow column, so that the clamp plate and the U-shaped plate cooperate with each other, improving the stability of the assembly of the U-shaped plate and the hollow column. The intermediate plate is installed between the first connecting ear and the second connecting ear, and the position of the clamp plate is restricted by the fasteners formed by screws and limit nuts. There is no need to increase the number of fasteners to restrict the position of the clamp plate, thus reducing the number of fasteners used. Attached Figure Description

[0033] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0034] Please see Figures 1-3This utility model provides a technical solution: a hazard warning device for civil engineering safety, including an alarm light 1. The lower end of the alarm light 1 is open, and a sleeve 11 is installed at the bottom of the alarm light 1, so that the upper end of the hollow column 2 is threadedly connected to the sleeve 11. At this time, the upper end of the hollow column 2 is inserted into the lower part of the alarm light 1 and maintains a constant relative position with the alarm light 1. The outer surface of the lower end of the hollow column 2 is machined with external threads. A U-shaped plate 5 is sleeved on the lower end of the hollow column 2. Two clamping nuts 4 are provided, and both clamping nuts 4 are threadedly connected to the lower end of the hollow column 2. The U-shaped plate 5 is placed between the two clamping nuts 4. A pressure ring 41 is provided on the upper side of the U-shaped plate 5. The pressure ring 41 is sleeved on the hollow column 2. A clamping nut 4 is provided on the upper side of the pressure ring 41. A rubber ring 42 is provided between the pressure ring 41 and the U-shaped plate 5. The rubber ring 42 is sleeved on the hollow column 2. The design of the pressure ring 41 and the rubber ring 42 improves the reliability of the clamping nut 4 in restricting the relative position of the U-shaped plate 5 and the hollow column 2.

[0035] See Figures 1-4 Two fixing holes 31 are provided on the vertical part of the base plate 3. First connecting ears 51 are installed at both ends of the U-shaped plate 5. The first connecting ears 51 and the U-shaped plate 5 are integrally formed. Two second connecting ears 32 are installed on the upper surface of the horizontal part of the base plate 3, which mate with the first connecting ears 51. The second connecting ears 32 are integrally formed with the base plate 3. The first connecting ears 51 are connected to the second connecting ears 32 by fasteners formed by screws 6 and limiting nuts 61. A rectangular groove 52 is provided on one side of the first connecting ear 51, penetrating the first connecting ear 51. A portion of the screw 6 is located within the rectangular groove 52. Through the cooperation of the screw 6 and the limiting nut 61, the first connecting ears 51 and the second connecting ears 32 can be securely connected, thus completing the assembly of the U-shaped plate 5 and the base plate 3. After assembly, the U-shaped plate 5 and the base plate 3 together form a positioning seat, which can stably limit the relative position between the hollow column 2 and the mounting carrier. If the screws securing the base plate 3 rust due to the damp environment at the construction site, preventing the base plate 3 from separating properly from the carrier, simply remove the screws 6 and the limiting nut 61 connecting the U-shaped plate 5 and the base plate 3 to separate the U-shaped plate 5 from the base plate 3, thus separating the alarm light 1 from the base plate 3. Even if the screws 6 and the limiting nut 61 connecting the first connecting ear 51 and the second connecting ear 32 are also rusted and stuck, preventing separation, the first connecting ear 51 has a rectangular groove 52. Part of the screw 6 is located within the rectangular groove 52, allowing the screw 6 to be directly cut off using the operating space provided by the rectangular groove 52, thus smoothly separating the U-shaped plate 5 from the base plate 3. This design provides multiple safeguards for the recycling of the alarm light 1, ensuring that even if some connecting parts rust and fail, the alarm light 1 can still be completely recycled and reused through simple operation, reducing equipment wear and cost waste.

[0036] See Figures 1-4A connecting plate 7 is provided at the upper part of one end of the U-shaped plate 5 near the bottom plate 3. Intermediate plates 71 are installed at both ends of the connecting plate 7. The intermediate plates 71 are inserted between the first connecting ear 51 and the second connecting ear 32. One end of a screw 6 passes through the second connecting ear 32, the intermediate plate 71, and the first connecting ear 51, and is threaded with a limit nut 61. A Z-shaped rod 72 is installed in the middle of the connecting plate 7. A clamping plate 73 is installed at the end of the Z-shaped rod 72 away from the connecting plate 7. The clamping plate 73 is slidably installed inside the U-shaped plate 5. A semi-circular groove 74 is machined on one side of the hollow column 2. The semi-circular groove 74 and the space inside the U-shaped plate 5 away from the bottom plate 3 form a circular channel for storing the hollow column 2. After the hollow column 2 is passed through the U-shaped plate 5, the clamping plate 73 is pushed so that the semi-circular groove 74 on its surface fits tightly against the outer wall of the hollow column 2. At this time, the clamping plate 73 and the inner wall of the U-shaped plate 5 form a mutually cooperating ring structure. By increasing the contact area, the stability of the connection between the U-shaped plate 5 and the hollow column 2 is improved, and the hollow column 2 is effectively prevented from shaking inside the U-shaped plate 5.

[0037] The intermediate plate 71 is inserted between the first connecting ear 51 and the second connecting ear 32. When the screw 6 passes through the second connecting ear 32, the intermediate plate 71, and the first connecting ear 51 and is tightened with the limiting nut 61, not only is the U-shaped plate 5 fixed to the base plate 3, but the intermediate plate 71 is also simultaneously limited. The intermediate plate 71, through the connecting plate 7 and the Z-shaped rod 72, drives the clamping plate 73 to maintain a tight grip on the hollow column 2. This design, using the same set of screws 6 and limiting nuts 61, simultaneously completes the connection between the U-shaped plate 5 and the base plate 3 and the position limitation of the clamping plate 73, eliminating the need for additional fasteners to fix the clamping plate 73, thereby reducing the number of fasteners used and simplifying the assembly process.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
