Description

Technical Field

[0001] The utility model relates to the technical field of road construction warning equipment, in particular to a road construction safety early warning device. Background Art

[0002] The road construction safety warning device is a type of traffic warning sign. It is placed at a suitable location in front of the construction site to inform passers-by that construction is ahead and they should slow down or take a detour to reduce the occurrence of safety accidents.

[0003] Most existing road construction safety warning methods use on-site brackets to support flashing warning lights for warning, so as to provide good warning work on foggy days and at night. However, the construction site environment is complex and there are many people. Construction workers may accidentally collide with the brackets during construction, causing the warning lights to fall over. After the warning lights fall over, they directly hit the ground, which can easily cause damage to the warning lights, making it inconvenient for users to use. Therefore, we propose a road construction safety warning device. Utility Model Content

[0004] One of the technical problems to be solved by this application is that the existing method generally uses a bracket to support the warning light for warning, but the construction site environment is complex and there are many people. Construction workers may accidentally collide with the bracket during construction, causing the warning light to fall over. After the warning light falls over, it directly collides with the ground, which can easily cause damage to the warning light, making it inconvenient for users to use.

[0005] To solve the above technical problems, the present invention provides a road construction safety warning device, comprising a connecting base, a plurality of equally spaced legs being rotatably connected to the circumference of the connecting base, a warning light being installed above the connecting base, and further comprising:

[0006] A linkage rod vertically passes through the center of the connecting seat and is slidably connected to the connecting seat, the warning light is installed on the top of the linkage rod, and a section of the linkage rod above the connecting seat is sleeved with a cylindrical protective tube, the bottom end of the protective tube is fixed to the upper surface of the connecting seat;

[0007] A support plate, the support plate is fixedly connected to the bottom end of the linkage rod, and a plurality of rotating rods corresponding to the legs are rotatably connected to the circumference of the support plate, and one end of the rotating rod away from the support plate is rotatably connected to the corresponding leg;

[0008] A tension spring is arranged below the rotating rod, one end of the tension spring is fixed to the supporting leg, and the other end of the tension spring is fixed to the supporting plate.

[0009] Preferably, the support leg includes a sliding tube with one end rotatably connected to the connecting seat, and the end of the sliding tube away from the connecting seat is slidably connected to a sliding rod, and a limit bolt threadedly connected to the side wall of the sliding tube is provided at the connection between the sliding tube and the sliding rod.

[0010] Preferably, the inner cavity depth of the casing is greater than the height of the warning light, a tubular buffer pad is embedded in the inner cavity of the casing, the outer wall of the buffer pad is fixed to the inner wall of the casing, and the inner diameter of the buffer pad is equal to the diameter of the warning light.

[0011] Preferably, when the legs are in an extended state, the bottom height of the warning light is higher than the top height of the protective tube; when the legs are in a retracted state, the bottom of the warning light fits into the upper surface of the connecting seat.

[0012] Preferably, an external thread is provided on the outer surface of the linkage rod, a screw ring is sleeved on the middle section of the linkage rod, and the screw ring is screwed to the linkage rod via the external thread.

[0013] Preferably, two ear plates are fixedly connected to the outer wall of one side of the protective tube, and a protective cover made of magnetic material is provided above the protective tube. The side of the protective cover close to the ear plate extends outward to form a joint, and the joint is embedded between the two ear plates. Connecting shafts are fixedly connected on both sides of the joint, and the end of the connecting shaft away from the joint is rotatably connected to the ear plate, and the protective cover is magnetically connected to the top of the protective tube.

[0014] Preferably, a torsion spring is sleeved on the middle section of the connecting shaft, one end of the torsion spring is fixedly connected to the joint, and the other end of the torsion spring is fixedly connected to the inner wall of the ear plate.

[0015] The utility model has at least the following beneficial effects:

[0016] 1. When the outriggers are overturned by external forces, the bottom of the outriggers loses its limiting effect on the roadbed. The tension springs in the stretched state will pull the outriggers toward the center of the support plate under their own elastic force, causing multiple outriggers to close at the same time. During the closing process, the outriggers push the support plate downward, and the linkage rod is used to pull the warning light into the casing to protect it, so as to avoid the warning light from hard collision with the ground when the entire device falls, which may cause damage to the warning light.

[0017] 2. A protective cover is connected to the top of the casing through a torsion spring. When the warning light is retracted into the casing, the protective cover can rotate around the connecting shaft under the elastic force of the torsion spring and cover the top of the casing to seal the opening at the top of the casing, thereby preventing external debris from entering the casing and hitting the warning light, causing damage to the warning light, thereby greatly improving the protection performance of the casing.

The tension spring 11 is used to pull the supporting leg to reset by its own elastic force; and further includes:

[0033] The leg includes a sliding tube 2 rotatably connected to the connecting seat 1 at one end, and a sliding rod 3 is slidably connected to the end of the sliding tube 2 away from the connecting seat 1. A limit bolt 4 is threadedly connected to the side wall of the sliding tube 2 at the connection between the sliding tube 2 and the sliding rod 3. The user can slide the sliding rod 3 to adjust the length of the entire leg as needed. After the adjustment is completed, the limit bolt 4 is tightened to fix the sliding tube 2 and the sliding rod 3;

[0034] The inner cavity depth of the casing 7 is greater than the height of the warning light 6. A tubular structure buffer pad 8 is embedded in the inner cavity of the casing 7.

During the unfolding process of the support legs, the tension spring 11 is stretched, and at the same time, the rotating rod 10 is pulled around the connection between it and the support leg and rotates upward, pushing the support plate 9 up, thereby driving the linkage rod 5 fixed with the bottom end and the support plate 9 to slide upward, pushing the warning light 6 out of the casing 7. The user turns on the warning light 6 and can warn through the flashing light of the warning light 6.

[0038] Example 2

[0039] See also Figure 5-7 , the utility model provides a technical solution:

[0040] Different from Example 1, this solution provides another implementation of the road construction safety early warning device:

[0041] A road construction safety warning device includes a connecting base 1, a plurality of equidistantly distributed supporting legs rotatably connected to the connecting base 1, a warning light 6 is installed above the connecting base 1, and further includes:

[0042] A linkage rod 5 vertically passes through the center of the connecting seat 1 and is slidably connected to the connecting seat 1. A warning light 6 is installed at the top of the linkage rod 5. A cylindrical protective tube 7 is sleeved on the circumference of the linkage rod 5 located above the connecting seat 1. The bottom end of the protective tube 7 is fixed to the upper surface of the connecting seat 1. When the linkage rod 5 slides down and pulls the warning light 6 downward, the warning light 6 can be embedded in the protective tube 7, and the protective tube 7 is used to protect the warning light 6.

[0043] A support plate 9 is fixedly connected to the bottom end of the linkage rod 5. A plurality of rotating rods 10 corresponding to the legs are rotatably connected to the circumference of the support plate 9. The ends of the rotating rods 10 away from the support plate 9 are rotatably connected to the corresponding legs.

[0044] A tension spring 11 is provided below the rotating rod 10, one end of the tension spring 11 being fixed to the supporting leg, and the other end of the tension spring 11 being fixed to the support plate 9. The tension spring 11 is used to pull the supporting leg to reset by its own elastic force; and further includes:

[0045] Two ear plates 13 are fixedly connected to the outer wall of one side of the casing 7. A protective cover 14 made of magnetic material is provided on the top of the casing 7. The side of the protective cover 14 close to the ear plate 13 extends outward to form a joint 15. The joint 15 is embedded between the two ear plates 13. A connecting shaft 16 is fixedly connected to both sides of the joint 15. The end of the connecting shaft 16 away from the joint 15 is rotatably connected to the ear plate 13.
