Description

Technical Field

[0001] This utility model relates to a temporary sign fixing frame for highways, belonging to the technical field of highway safety maintenance equipment. Background Technology

[0002] With the rapid development of expressways, traffic volume on expressways is gradually increasing, and the pressure on expressway maintenance and construction is also increasing. In accordance with the requirements of maintenance safety operation procedures, higher requirements are placed on the placement of safety signs and markers for expressway construction.

[0003] Currently, when setting up temporary signs and markers for safety and construction guidance during highway maintenance, sandbags or similar materials are mostly used to fix the sign mounting frames to the road surface. This method of fixing signs has the drawback of being unreliable, and the signs often tilt or fall over due to strong winds or airflow impacts, posing a safety hazard.

[0004] Therefore, there is an urgent need for a fast and convenient tool for setting up signs. Utility Model Content

[0005] To address the aforementioned shortcomings in existing technologies, this utility model provides a highway temporary sign fixing frame that is simple in structure, easy to install, and reliable in fixation.

[0006] This utility model is achieved through the following technical solution: a temporary highway sign fixing bracket, characterized in that it includes a column, a locking structure, and a sign fixing structure. The column includes an upper column and a lower column that are telescopically fitted together. An adjusting screw is provided between the top ends of the upper column and the lower column. The adjusting screw is threadedly connected to the top plate of the upper column. The lower end of the adjusting screw passes through the top plate of the lower column. Stops are fixed on the adjusting screw located at the upper and lower parts of the top plate of the lower column, respectively. An operating handle is provided at the top end of the adjusting screw. The locking structure includes... The sign includes an upper horizontal bar fixed to the outside of the upper column and a lower horizontal bar fixed to the outside of the lower column. The upper and lower horizontal bars are parallel. Each end of the upper horizontal bar is connected to a first V-shaped clamp with its opening facing downwards, and each end of the lower horizontal bar is connected to a second V-shaped clamp with its opening facing upwards. Both the first and second V-shaped clamps are located on the rear side of the column. The sign fixing structure includes two fixing sleeves, which are fixed to the outer walls of the upper and lower columns respectively, and both fixing sleeves are located on the front side of the column. Fastening screws are provided on the fixing sleeves.

[0007] In this invention, an adjusting screw can be rotated via an operating handle. Rotating the adjusting screw allows for the extension and retraction of the upper and lower posts, thereby adjusting the distance between the first and second V-shaped clamps. Two fixing sleeves are used to install the mounting rod of the sign. After the mounting rod of the sign is inserted into the fixing sleeves, it is fixed with fastening screws. In use, based on the height of the highway corrugated guardrail, after adjusting the distance between the first and second V-shaped clamps using the adjusting screw, the first and second V-shaped clamps are respectively clamped onto the upper and lower ends of the highway corrugated guardrail. Rotating the adjusting screw via the operating handle causes the upper and lower posts to retract, thus securing the first and second V-shaped clamps onto the highway corrugated guardrail. Finally, the mounting rod of the sign is inserted into the two fixing sleeves and fixed with fastening screws.

[0008] Furthermore, the inner wall of the fixing sleeve is fixed with 1-3 elastic clips. By setting elastic clips inside the fixing sleeve, it can be ensured that the mounting rod of the sign is reliably inserted into the fixing sleeve and fixed, and it can prevent the mounting rod of the sign from tilting when subjected to strong winds or airflow impacts.

[0009] Furthermore, the columns, upper crossbars, and lower crossbars are all made of aluminum alloy square tubing.

[0010] Furthermore, to ensure the reliability of the fixing bracket on the highway guardrail, the distance between the two first V-shaped clamps is greater than the distance between the two second V-shaped clamps.

[0011] The beneficial effects of this utility model are as follows: This utility model has a simple structure. Through its unique clamping structure, it can be quickly and securely installed on highway corrugated guardrails. No additional tools are required for assembly and disassembly, making both installation and removal simple and quick. The posts in this utility model have a telescopic adjustment function. By adjusting the screw, the telescopic relationship between the upper and lower posts can be easily adjusted, allowing the first and second V-shaped clamps to be easily engaged or disengaged from the highway corrugated guardrail. Simultaneously, the telescopic nature of the posts allows for adaptation to guardrails of different sizes, improving the adaptability of this utility model's installation. This utility model can be securely installed on highway corrugated guardrails, providing reliable fixation and effectively resisting the impact of strong winds and high-speed airflows, preventing it from easily falling off or tilting. The overall structure of this utility model is compact; the posts are small in size when folded, allowing for easy carrying and operation by a single person. This significantly improves the efficiency of sign placement in emergency warning and construction guidance scenarios, providing reliable support for safe highway operations.

[0019] The present invention will be further described below through non-limiting embodiments and in conjunction with the accompanying drawings:

[0020] As attached Figures 1-4As shown, a temporary highway sign fixing bracket includes a column, a clamping structure, and a sign fixing structure. The column comprises an upper column 1 and a lower column 4 that are telescopically fitted together. Both the upper column 1 and the lower column 4 are made of aluminum alloy square tubing. A top plate 1.1 and a top plate 4.1 are fixed to the top of the upper column 1. An adjusting screw 8 with external threads is provided between the top of the upper column 1 and the top of the lower column 4. A threaded hole is provided on the top plate 1.1 of the upper column, and the adjusting screw 8 is threadedly connected to the top plate 1.1 of the upper column. A through hole is provided on the top plate 4.1 of the lower column, and the lower end of the adjusting screw 8 passes through the top plate 4.1 of the lower column. Stops 8.1 are fixed to the upper and lower parts of the adjusting screw 8 on the top and bottom of the top plate of the lower column, respectively. An operating handle 7 is fixed to the top of the adjusting screw 8. The fastening structure includes an upper horizontal bar 2 fixed to the outside of the upper column 1 and a lower horizontal bar 6 fixed to the outside of the lower column 4. Both the upper horizontal bar 2 and the lower horizontal bar 6 are made of aluminum alloy square tubing, and the upper horizontal bar 2 and the lower horizontal bar 6 are parallel. The upper horizontal bar 2 can be fixed to the upper column 1 by welding a single horizontal bar, or it can be fixed to both sides of the upper column 1 by symmetrical welding two short horizontal bars. The lower horizontal bar 6 is welded to the lower end of the lower column 4. Each end of the upper horizontal bar 2 is connected to a first V-shaped clamp 3 with its opening facing downwards, and each end of the lower horizontal bar 6 is connected to a second V-shaped clamp 5 with its opening facing upwards. Both the first V-shaped clamp 3 and the second V-shaped clamp 6 are located on the rear side of the column. The first V-shaped clamp 3 and the second V-shaped clamp 6 can be made of angle aluminum. The sign fixing structure includes two fixing sleeves 9, which are respectively fixed to the outer walls of the upper column 1 and the lower column 4, and both fixing sleeves 9 are located on the front side of the columns. Fastening screws 10 are provided on the fixing sleeves 9. The fixing sleeves 9 are used to insert the mounting rod of the sign. The fixing sleeves 9 are made of aluminum alloy.

[0021] To ensure that the fixing bracket is reliably fixed on the guardrail, and to reduce the size of the fixing bracket for easy carrying, it is preferable that the distance between the two first V-shaped clamps 3 is greater than the distance between the two second V-shaped clamps 5.

[0022] This utility model is used to fix the corrugated guardrail of a highway. During installation, according to the size of the guardrail, the adjusting screw 8 is rotated by operating handle 7 to extend and retract the upper post 1 and the lower post 4, thereby adjusting the distance between the first V-shaped clamp 3 and the second V-shaped clamp 5 to match the height of the guardrail. After adjusting the distance between the first V-shaped clamp 3 and the second V-shaped clamp 5, the two first V-shaped clamps 3 on the upper crossbar 2 and the two second V-shaped clamps on the lower crossbar 6 are respectively clamped at the upper and lower ends of the highway corrugated guardrail. Then, the adjusting screw 8 is rotated by operating handle 7 to contract and tighten the upper post 1 and the lower post 4, thereby clamping the first V-shaped clamp 3 and the second V-shaped clamp 5 onto the highway corrugated guardrail. Finally, the mounting rod of the sign is inserted into the two fixing sleeves 9 and fixed with fastening screws 10.

[0023] As attached Figure 5 As shown, in order to ensure that the mounting rod of the sign is reliably inserted into the fixing sleeve and to prevent the mounting rod of the sign from tilting when subjected to strong winds or airflow, 1-3 elastic clips 11 can also be fixed on the inner wall of the fixing sleeve 9. The elastic clips 11 can be welded to the inner wall of the fixing sleeve 9.

[0024] This utility model has a simple structure and can be quickly and securely installed on highway corrugated guardrails. It can also quickly and conveniently deploy safety and construction signs. Installation and disassembly are simple and convenient, and a single person can easily complete the installation and disassembly work. No additional tools are required for installation and disassembly, making it highly practical.

[0025] The other parts in this embodiment are all existing technologies and will not be described in detail here.
