[0025] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example:

[0027] See also Figure 1-Figure 4 , a highway construction safety warning device, comprising:

[0028] Alert box 1; and

[0029] Two groups of slogan board closing mechanisms 2, the two groups of slogan board closing mechanisms 2 are respectively arranged at the top and bottom of the warning frame 1, the slogan board closing mechanism 2 includes a control box 201, a connecting plate 202, three transmission tooth plates 204, three transmission gears 205, a transmission threaded rod 206 and three sealing blocks 208, the control box 201 is fixedly connected to the outer surface of one side of the warning frame 1, the transmission threaded rod 206 penetrates the inner wall of one side of the control box 201, and the transmission threaded rod 206 is threadedly connected to the control box 201, the connecting plate 202 is rotatably connected to one end of the transmission threaded rod 206, the three transmission tooth plates 204 are all fixedly connected to the bottom of the connecting plate 202, the three transmission gears 205 are all rotatably connected between the inner walls on both sides of the control box 201, and each transmission gear 205 is meshed with the corresponding transmission tooth plate 204, the three sealing blocks 208 are all rotatably connected to the outer surface of one side of the control box 201, and the three sealing blocks 208 are respectively fixedly connected to the three transmission gears 205.

[0030] In a specific embodiment of the present invention, a square plate printed with a warning slogan is placed in the embedded groove on the front side of the warning frame 1, and six sealing blocks 208 will seal the square plate in the embedded groove of the warning frame 1. By controlling the two transmission threaded rods 206 to rotate, each transmission threaded rod 206 moves in a direction away from the corresponding control box 201, and each transmission threaded rod 206 drives the corresponding connecting plate 202 to move, so that the three transmission tooth plates 204 on each connecting plate 202 drive the corresponding three transmission gears 205 to rotate, so that the six sealing blocks 208 on the two sets of slogan board sealing mechanisms 2 By rotating, the six sealing blocks 208 will not block the embedded groove of the warning frame 1, so that the warning slogan board inside the embedded groove of the warning frame 1 can be taken out, and then a new warning slogan board can be put in. By controlling the two transmission threaded rods 206 to rotate in the opposite direction, the six sealing blocks 208 are finally driven to seal the warning slogan board in the embedded groove of the warning frame 1 again, so as to realize the rapid replacement of the slogan board. Compared with the traditional road construction warning board that needs to be completely scrapped when damaged, when the warning slogan board designed by the device is damaged, only the damaged part needs to be replaced, without scrapping the entire warning frame 1 or other related components. This greatly reduces the cost of maintenance and replacement and reduces unnecessary waste.

[0031] Specifically, the slogan board closing mechanism 2 further includes two limit rods 203 . The two limit rods 203 are fixedly connected between the inner walls on both sides of the control box 201 , and the connecting plate 202 is slidably sleeved on the two limit rods 203 .

[0032] In this embodiment, the two limiting rods 203 enable the two connecting plates 202 to maintain stable movement, ensuring that the three transmission gear plates 204 and the three transmission gears 205 maintain stable meshing respectively.

[0033] Specifically, each limiting rod 203 is made of stainless steel.

[0034] In this embodiment, the limiting rod 203 is made of stainless steel, which is more durable, has a smooth surface and low friction.

[0035] Specifically, the slogan board closing mechanism 2 further includes a butterfly handle 207 , and the butterfly handle 207 is fixedly connected to one end of the transmission threaded rod 206 .

[0036] In this embodiment, the butterfly handle 207 facilitates the operator to rotate the transmission threaded rod 206 .

[0037] Specifically, the butterfly handle 207 is made of bakelite.

[0038] In this embodiment, the butterfly handle 207 is made of bakelite. The bakelite handle is resistant to acid and alkali and aging, so it can be installed on outdoor machinery and withstand the baptism of wind and rain without fading, deformation or brittleness.

[0039] Specifically, a support frame 3 is fixedly connected to the rear outer surface of the warning frame 1 .

[0040] In this embodiment, the support frame 3 is used to support the warning frame 1 .

[0041] Working principle: by rotating the two butterfly handles 207, the two transmission threaded rods 206 are controlled to rotate, so that each transmission threaded rod 206 moves in a direction away from the corresponding control box 201, and each transmission threaded rod 206 drives the corresponding connecting plate 202 to move, so that the three transmission tooth plates 204 on each connecting plate 202 drive the corresponding three transmission gears 205 to rotate, so that the six sealing blocks 208 on the two groups of slogan board closing mechanisms 2 rotate, so that the six sealing blocks 208 will not block the embedded groove of the warning frame 1, so that the warning slogan board inside the embedded groove of the warning frame 1 can be taken out, and then a new warning slogan board can be put in, and by controlling the two transmission threaded rods 206 to rotate in the opposite direction, the six sealing blocks 208 are finally driven to re-seal the warning slogan board in the embedded groove of the warning frame 1, so as to realize the rapid replacement of the slogan board. Compared with the traditional road construction warning board that needs to be completely scrapped when damaged, the warning slogan board designed by the device only needs to replace the damaged part when it is damaged, without scrapping the entire warning frame 1 or other related components. This greatly reduces the cost of maintenance and replacement and reduces unnecessary waste.

[0042] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be included in the protection scope of the utility model.
