Description

Technical Field

[0001] This utility model relates to the field of highway construction technology, specifically to a temporary installation structure for highway signs. Background Technology

[0002] In highway construction, maintenance, and special event handling, the installation of temporary signs is crucial, providing timely and accurate warnings and guidance information to passing vehicles and pedestrians. Common temporary signs often use a cross-shaped base with a steel pipe stand. While simple to manufacture, this structure is prone to tilting or falling due to its high center of gravity and the impact of airflow or wind generated by vehicles, significantly reducing its warning effect. To prevent the signs from tilting or falling, counterweights (such as sandbags, stones, or concrete blocks) are placed on the base after installation to increase stability. However, transporting these counterweights to the installation site is time-consuming and laborious, and cleaning them after use is equally troublesome. Furthermore, carelessly discarding counterweights can damage the surrounding environment. Even with counterweights, temporary signs may still sway or tilt slightly due to instability in strong winds or the strong airflow generated by high-speed vehicles, failing to fundamentally solve the problem. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model discloses a temporary installation structure for highway signs. The technical solution adopted includes a support plate and a corrugated guardrail. The support plate is cross-shaped. A movable plate is slidably installed in the groove at the bottom of the support plate. The bottom of the movable plate is fixedly connected to the middle of the top of the support rod. Inserts are fixedly installed on the sides of both the support plate and the movable plate. Signs are inserted into two of the inserts. Locking mechanisms for fixing the signs are installed on both inserts. L-shaped fixing plates are fixedly installed on the sides of both ends of the support plate and both ends of the support rod. The fixing plates cooperate with the edges of the corrugated guardrail. A lead screw is rotatably mounted on the top of the groove on the support plate. The lead screw is threadedly connected to the threaded hole at the top of the movable plate. A rotating seat is rotatably mounted on the top of the support plate. The shaft at the bottom of the rotating seat passes through the through hole at the top of the support plate and is fixedly connected to the top of the lead screw. A push rod is inserted into the through hole at the upper end of the rotating seat. The diameter of both ends of the push rod is larger than the diameter of the through hole on the rotating seat.

[0004] As a preferred technical solution of this utility model, the locking mechanism includes a bolt, a fixing nut and a pressure plate. The fixing nut is fixedly installed on the side of the insert. A through hole corresponding to the fixing nut is opened on the side of the insert. One end of the bolt passes through the screw hole on the fixing nut and is rotatably connected to the side of the pressure plate. The pressure plate is arc-shaped and cooperates with the sign.

[0005] As a preferred embodiment of this utility model, one end of the bolt is in the shape of a triangular ring.

[0006] As a preferred embodiment of this utility model, a foam board is fixedly installed on the inner side of the fixing plate, and the foam board cooperates with the corrugated guardrail.

[0007] As a preferred embodiment of this utility model, the side of the fixing plate is fixedly connected to the side of the fixing cylinder, and the side of the fixing cylinder is fixedly connected to the sides of both ends of the support rod or the sides of both lateral ends of the support plate.

[0008] As a preferred technical solution of this utility model, the flat plate at the top of the sign is a fiberglass board with a reflective paint coating on its surface.

[0009] The beneficial effects of this utility model are as follows: 1. This utility model uses a push rod to drive the rotating seat and the lead screw to rotate, causing the lead screw to drive the moving plate to move upward, so that the support plate and the fixed plate on the moving plate are clamped onto the corrugated guardrail, thus fixing the support plate and the moving plate. The locking mechanism presses and fixes the signboard into the insert, so that the signboard can remain stable during use and will not tilt or fall over under the action of airflow and wind generated by vehicle movement. Moreover, the signboard can be directly fixed to the corrugated guardrail without additional counterweight, which is convenient to install and has high stability. It can fundamentally solve the problem of unstable signboards during temporary highway maintenance and construction, which affects the warning function of the signboards.

[0010] 2. The bolt drives the pressure plate to move, pressing the column part at the bottom of the sign into the insert to keep it stable. The outer end of the bolt is triangular and ring-shaped to increase the gripping area and make it easier for people to operate.

[0011] 3. Foam board can provide protection for the corrugated guardrail, preventing paint peeling when the guardrail comes into contact with the fixing plate. Fixing cylinder can increase the fixing area between the fixing plate and the support plate and support rod, improving the strength of the fixing plate. The flat sign display area made of fiberglass material is lighter and has a lower center of gravity than traditional iron signs, and has the advantages of easy installation, handling and good stability.

Detailed Implementation

[0019] Example 1

[0020] like Figures 1 to 6As shown, this utility model discloses a temporary installation structure for highway signs. The technical solution includes a support plate 1 and a corrugated guardrail 8. The support plate 1 is cross-shaped, and a movable plate 2 is slidably installed in the groove at the bottom of the support plate 1. The bottom of the movable plate 2 is fixedly connected to the middle of the top of the support rod 3. Insert cylinders 4 are fixedly installed on the sides of both the support plate 1 and the movable plate 2. Signs 5 are inserted into the two insert cylinders 4. Locking mechanisms 6 for fixing the signs 5 are installed on both insert cylinders 4. The flat plate at the top of the sign 5 is made of fiberglass board and coated with reflective paint. The locking mechanism 6 includes a bolt 61, a fixing nut 62, and a pressure plate 63. The fixing nut 62 is fixedly installed on the side of the insert cylinder 4. The side of the insert cylinder 4 has a locking mechanism for fixing the sign 5. The nut 62 has a corresponding through hole. One end of the bolt 61 passes through the screw hole on the fixing nut 62 and is rotatably connected to the side of the pressure plate 63. The outer end of the bolt 61 is triangular. The pressure plate 63 is arc-shaped and cooperates with the sign 5. The bolt 61 drives the pressure plate 63 to move, so that the pressure plate 63 presses the column part of the lower part of the sign 5 into the insert 4 to keep it stable. The triangular ring shape of the outer end of the bolt 61 increases the gripping area and facilitates operation. L-shaped fixing plates 7 are fixedly installed on the sides of both ends of the support plate 1 and both ends of the support rod 3. The fixing plates 7 cooperate with the edge of the corrugated guardrail 8. Foam board 12 is fixedly installed on the inner side of the fixing plate 7. The foam board 12 and the corrugated guardrail 8 are fixedly installed. In conjunction with this, the foam board 12 provides protection for the corrugated guardrail 8, preventing paint peeling when the corrugated guardrail 8 comes into contact with the fixing plate 7. The side of the fixing plate 7 is fixedly connected to the side of the fixing cylinder 13, and the side of the fixing cylinder 13 is fixedly connected to the sides of both ends of the support rod 3 or the sides of both lateral ends of the support plate 1. The fixing cylinder 13 increases the fixing area between the fixing plate 7 and the support plate 1 and the support rod 3, thereby improving the strength of the fixing plate 7. A lead screw 9 rotates on the top of the groove on the support plate 1, and the lead screw 9 is threadedly connected to the threaded hole on the top of the moving plate 2. A rotating seat 10 is rotatably installed on the top of the support plate 1. The shaft at the bottom of the rotating seat 10 passes through the through hole at the top of the support plate 1 and is fixedly connected to the top of the lead screw 9. The through hole at the upper end of the rotating seat 10... A push rod 11 is inserted inside. The diameter of both ends of the push rod 11 is larger than the diameter of the through hole on the rotating seat 10. The push rod 11 drives the rotating seat 10 and the lead screw 9 to rotate, causing the lead screw 9 to drive the moving plate 2 to move upward. This clamps the support plate 1 and the fixed plate 7 on the moving plate 2 onto the corrugated guardrail 8, thus fixing the support plate 1 and the moving plate 2. The locking mechanism 6 presses and fixes the sign 5 into the insert 4, ensuring that the sign 5 remains stable during use and will not tilt or fall over due to airflow and wind generated by vehicle movement. It is directly fixed to the corrugated guardrail without additional counterweight, making installation convenient and highly stable. This fundamentally solves the problem of unstable signs affecting the warning function during temporary highway maintenance and construction.The working principle of this utility model is as follows: The support plate 1 is placed next to the corrugated guardrail 8, and the fixing plate 7 on the support plate 1 is hung on the corrugated guardrail 8 beside the road. The push rod 11 is held and rotated. The rotation of the push rod 11 causes the rotating seat 10 to rotate as well. Because the shaft at the bottom of the rotating seat 10 passes through the through hole at the top of the support plate 1 and is fixedly connected to the top of the lead screw 9, the rotation of the rotating seat 10 will drive the lead screw 9 to rotate. The lead screw 9 is threadedly connected to the threaded hole at the top of the moving plate 2. When the lead screw 9 rotates, according to the principle of threaded transmission, the lead screw 9 will drive the moving plate 2 to move upward within the groove at the bottom of the support plate 1. As the moving plate 2 moves upward, the support rod 3 and the fixing plate 7 of the support rod 3, which are fixedly connected to the moving plate 2, will also move upward synchronously. When the fixing plate 7 on the support rod 3 moves to contact the edge of the corrugated guardrail 8, it continues to rotate. Push rod 11 causes fixing plate 7 to be tightly clamped onto corrugated guardrail 8, thereby stably fixing support plate 1 and moving plate 2 onto corrugated guardrail 8. Insert the post part of sign 5 into insert 4, hold the triangular ring-shaped end of bolt 61, and rotate bolt 61. Since bolt 61 is threadedly connected to fixing nut 62, bolt 61 will move along the threaded hole of fixing nut 62 during rotation, thereby driving pressure plate 63 closer to sign 5. Since pressure plate 63 is arc-shaped and matches sign 5, as bolt 61 rotates, pressure plate 63 will gradually press the post part of the lower part of sign 5 into insert 4, thereby stably fixing sign 5 onto corrugated guardrail 8. During use, even if it is subjected to airflow or wind impact generated by vehicle movement, the temporary sign can remain stable and will not tilt or fall over.

[0021] It is worth noting that in actual use, this utility model can be adapted to the installation and practical use of three-wave guardrails and double-wave guardrails because the support plate 1 and the moving plate 2 are connected by a screw rod 9 and the distance between the fixed plate 7 on the support plate 1 and the moving plate 2 is adjustable.

[0022] Components not described in detail in this article are existing technologies.

[0023] While the specific embodiments of this utility model have been described in detail above, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model. Modifications or variations that do not involve creative labor are still within the protection scope of this utility model.
