Technical Field
[0001] This utility model belongs to the field of road and bridge construction technology, and in particular relates to a safety warning device for road and bridge construction. Background Technology
[0002] Safety warning devices for road and bridge construction refer to a series of warning devices and signs installed during road and bridge construction to ensure the safety of construction workers, pedestrians, and vehicles. These devices can remind people of the dangers in the construction area and prevent accidents. In summary, the existing technology has the following problems: Safety warning signs for road and bridge construction are a type of warning device. The surface of the safety warning sign has warning information, and it is placed in the construction area. Usually, the safety warning sign is installed on the warning sign bracket frame with bolts. Improper bolt installation can easily lead to instability, and the bolts require regular maintenance and inspection, increasing maintenance costs. The bolts are also susceptible to weather conditions; if the bolts rust and age in a humid environment, the safety warning sign may fall off. However, existing safety warning devices used in road and bridge construction lack components for more stable installation of the safety warning signs. Therefore, a new safety warning device for road and bridge construction is proposed to solve the above problems. Utility Model Content
[0003] To address the problems existing in the prior art, this utility model provides a safety warning device for road and bridge construction. This device offers the advantage of more stable installation of safety warning signs during road and bridge construction. It solves the problem that existing safety warning signs for road and bridge construction, which are essentially warning devices with warning information on their surface, are simply placed in the construction area. Typically, the signs are bolted to a support frame, which is prone to instability if the bolts are not installed correctly. Furthermore, the bolts require regular maintenance and inspection, increasing maintenance costs. They are also susceptible to weather conditions; if the bolts rust or age in humid environments, the safety warning signs may fall off. However, existing safety warning devices for road and bridge construction lack components for more stable installation of the signs.
[0004] This utility model is implemented as follows: a safety warning device for road and bridge construction includes a safety warning sign and a warning sign support frame. The inner cavity of the warning sign support frame is movably connected to the surface of the safety warning sign. Device shells are fixedly connected to both the left and right sides of the warning sign support frame. A top cover is movably connected to the top of the warning sign support frame. The surface of the top cover is in contact with the surface of the device shell. A locking device is provided in the inner cavity of the device shell.
[0005] As a preferred embodiment of this utility model, the positioning device includes two positioning levers. The opposite sides of the two positioning levers penetrate the device shell and extend to the outer side of the inner cavity of the device shell. The surface of the positioning levers is provided with square shifting holes. The opposite sides of the two positioning levers are fixedly connected with springs. By setting the positioning device, when the top cover moves to the top of the warning sign bracket frame, the positioning device has a limiting effect on the position of the top cover.
[0006] As a preferred embodiment of this utility model, the inner cavity of the device housing is fixedly connected to two movable folding rods that cooperate with the square shifting holes. The surface of the movable folding rods is movably connected to the inner cavity of the square shifting holes. The opposite sides of the two springs are fixedly connected to the surface of the movable folding rods. By setting the movable folding rods and the square shifting holes, when the locking folding rods move, they will drive the square shifting holes to move along the surface of the movable folding rods. The cooperation between the movable folding rods and the square shifting holes has a limiting effect on the movement position of the locking folding rods.
[0007] In a preferred embodiment of this invention, each of the two locking levers is fixedly connected to a pressing angled rod on its opposite side. A control pressing column, which works in conjunction with the pressing angled rod, is movably connected to the inner cavity of the device housing. The surface of the control pressing column contacts the surface of the pressing angled rod. The side of the control pressing column away from the warning sign bracket frame penetrates the device housing and extends to the outer side of the inner cavity of the device housing. By setting the pressing angled rod and the control pressing column, when the control pressing column moves, it can generate a pressing force on the pressing angled rod. The two pressing angled rods subjected to the pressing force will move simultaneously. When the pressing angled rods move, they can drive the locking levers to move.
[0008] In a preferred embodiment of this invention, an auxiliary housing is fixedly connected to the surface of the control extrusion column, and an auxiliary inner rod is movably connected to the inner cavity of the auxiliary housing. The surface of the auxiliary inner rod is fixedly connected to the inner cavity of the device housing. By setting the auxiliary housing and the auxiliary inner rod, when the control extrusion column moves, it will drive the auxiliary housing to move along the surface of the auxiliary inner rod. The combined use of the auxiliary housing and the auxiliary inner rod has a limiting effect on the movement position of the control extrusion column.
[0009] As a preferred embodiment of this utility model, two sliding blocks are fixedly connected to both the left and right sides of the top cover, and two sliding frames that cooperate with the sliding blocks are fixedly connected to both the left and right sides of the warning sign bracket frame. The surface of the sliding block is movably connected to the inner cavity of the sliding frame. The side of the sliding block near the locking lever passes through the sliding frame and extends to the outer side of the inner cavity of the sliding frame. By setting the sliding blocks and sliding frames, when the top cover moves, it will drive the sliding blocks to move along the inner cavity of the sliding frame. The cooperation of the sliding blocks and sliding frames has a limiting effect on the movement position of the top cover.
[0010] As a preferred embodiment of this utility model, the surface of the sliding block is provided with a locking groove for use with the locking lever. The surface of the locking lever contacts the inner cavity of the locking groove. By setting the locking groove, when the top cover moves to the top of the warning sign bracket frame, the control squeezing column is released, and the restoring force generated by the spring returning to its shape will drive the locking lever to be locked into the inner cavity of the locking groove. The cooperation between the locking lever and the locking groove has a limiting effect on the position of the top cover.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model solves the problem of existing road and bridge construction safety warning signs, which are a type of warning device, with warning content on their surface, and are placed in the construction area. These signs are typically bolted to a warning sign bracket frame. Improper bolt installation can easily lead to instability, and the bolts require regular maintenance and inspection, increasing maintenance costs. Furthermore, the bolts are susceptible to weather conditions; if they rust or age in humid environments, the safety warning sign may fall off. However, existing road and bridge construction safety warning devices lack components for more stable installation of the signs.
[0013] 2. This utility model, by setting a locking device, can drive the two locking folding rods to move closer to each other when the squeezing slant rod moves. When the locking folding rod moves, it will drive the square moving hole to move along the surface of the moving folding rod. At the same time, the squeezing force generated when the locking folding rod moves will cause the spring to undergo elastic deformation. The restoring force generated by the spring returning to its shape will drive the locking folding rod to be locked into the inner cavity of the locking groove. The locking device has a limiting effect on the position of the top cover. Attached Figure Description

The surface of the locking levers 501 is provided with square shifting holes 502. The opposite sides of the two locking levers 501 are fixedly connected with springs 503.
[0023] The above solution is adopted: by setting the locking device 5, when the top cover 4 moves to the top of the warning sign bracket frame 2, the locking device 5 has a limiting effect on the position of the top cover 4.
[0024] refer to Figure 4 The inner cavity of the device housing 3 is fixedly connected to two movable folding rods 6 that cooperate with the square shifting hole 502. The surface of the movable folding rod 6 is movably connected to the inner cavity of the square shifting hole 502. The opposite sides of the two springs 503 are fixedly connected to the surface of the movable folding rod 6.
[0025] The above solution is adopted: by setting the movable folding rod 6 and the square shifting hole 502, when the locking folding rod 501 moves, it will drive the square shifting hole 502 to move along the surface of the movable folding rod 6. The cooperation of the movable folding rod 6 and the square shifting hole 502 has a limiting effect on the movement position of the locking folding rod 501.
[0026] refer to Figure 4Two clamping levers 501 are fixedly connected to the opposite side of each other with a squeezing angled rod 7. The inner cavity of the device housing 3 is movably connected with a control squeezing column 8 that works with the squeezing angled rod 7. The surface of the control squeezing column 8 is in contact with the surface of the squeezing angled rod 7. The side of the control squeezing column 8 away from the warning sign bracket frame 2 passes through the device housing 3 and extends to the outside of the inner cavity of the device housing 3.
[0027] The above scheme is adopted: by setting the extrusion bar 7 and the control extrusion column 8, when the control extrusion column 8 moves, it can generate extrusion force on the extrusion bar 7. The two extrusion bars 7 subjected to the extrusion force will move simultaneously. When the extrusion bar 7 moves, it can drive the locking lever 501 to move.
[0028] refer to Figure 4 An auxiliary housing 9 is fixedly connected to the surface of the control extrusion column 8, and an auxiliary inner rod 10 is movably connected to the inner cavity of the auxiliary housing 9.

[0029] The above scheme is adopted: by setting the auxiliary housing 9 and the auxiliary inner rod 10, when the control extrusion column 8 moves, it will drive the auxiliary housing 9 to move along the surface of the auxiliary inner rod 10. The cooperation of the auxiliary housing 9 and the auxiliary inner rod 10 has a limiting effect on the movement position of the control extrusion column 8.
[0030] refer to Figure 2 Two sliding blocks 11 are fixedly connected to the left and right sides of the top cover 4. Two sliding frames 12 that cooperate with the sliding blocks 11 are fixedly connected to the left and right sides of the warning sign bracket frame 2. The surface of the sliding block 11 is movably connected to the inner cavity of the sliding frame 12. The side of the sliding block 11 near the locking lever 501 passes through the sliding frame 12 and extends to the outside of the inner cavity of the sliding frame 12.

The cooperation of the sliding block 11 and the sliding frame 12 has a limiting effect on the movement position of the top cover 4.
[0032] refer to Figure 3 The surface of the sliding block 11 is provided with a positioning groove 13 that works in conjunction with the positioning lever 501, and the surface of the positioning lever 501 contacts the inner cavity of the positioning groove 13.
[0033] The above solution is adopted: by setting the locking groove 13, when the top cover 4 moves to the top of the warning sign bracket frame 2, the control squeezing column 8 is released, and the restoring force generated by the spring 503 returning to its shape will drive the locking lever 501 to be locked into the inner cavity of the locking groove 13. The cooperation between the locking lever 501 and the locking groove 13 has a limiting effect on the position of the top cover 4.
[0034] The working principle of this utility model:
[0035] When using the safety warning device for road and bridge construction, if a more stable installation of the safety warning sign 1 is required, the user first places the safety warning sign 1 into the inner cavity of the warning sign bracket frame 2, and then pushes the control compression column 8 backward. When the control compression column 8 moves, it will cause the auxiliary housing 9 to move along the surface of the auxiliary inner rod 10. When the control compression column 8 moves, it can cause the two compression diagonal rods 7 to move closer to each other. When the compression diagonal rods 7 move, it can cause the two locking bending rods 501 to move closer to each other. When the locking bending rods 501 move, it will cause the square moving hole 502 to move along the surface of the moving bending rod 6. At the same time, the compression force generated when the locking bending rods 501 move will... The spring 503 undergoes elastic deformation. When the locking lever 501 is fully moved into the inner cavity of the device housing 3, the top cover 4 moves forward. When the top cover 4 moves, it will drive the sliding block 11 to move along the inner cavity of the sliding frame 12. When the top cover 4 moves to the top of the warning sign bracket frame 2, the control compression column 8 is released. The restoring force generated by the spring 503 returning to its shape will drive the locking lever 501 to be locked into the inner cavity of the locking groove 13. The cooperation between the locking lever 501 and the locking groove 13 has a limiting effect on the position of the sliding block 11 and the top cover 4. The setting of the top cover 4 has a limiting effect on the position of the safety warning sign 1. At this time, the safety warning device used in road and bridge construction completes a more stable installation of the safety warning sign 1.
[0036] In summary, this safety warning device for road and bridge construction, through the coordinated use of the locking device 5, locking lever 501, square shifting hole 502, spring 503, and locking groove 13, solves the problem that existing safety warning signs for road and bridge construction, which are a type of warning device with warning content on their surface, are simply placed in the construction area. Typically, safety warning signs are bolted to the warning sign bracket frame, but improper bolt installation can easily lead to instability. Furthermore, the bolts require regular maintenance and inspection, increasing maintenance costs. The bolts are also susceptible to weather conditions; if they rust or age in humid environments, the safety warning sign may fall off. However, existing safety warning devices for road and bridge construction lack components for more stable installation of the safety warning signs.
