Description

Technical Field

[0001] The utility model relates to the technical field of guardrail plates, in particular to a guardrail plate with a hollow structure. Background Art

[0002] The main function of the guardrail plate is to enhance road safety and reduce the possibility of vehicles deviating from the road or having accidents. The guardrail plate is used in various scenarios, including but not limited to the edges of roads, highway dividers, entrances of bridges and tunnels, construction sites, airports, and parking lots, etc. Therefore, the guardrail plate plays an important role in road and traffic infrastructure, helping to maintain road safety and traffic order.

[0003] However, when installing the existing guardrail plates, most of them are assembled and connected by screws. Especially when the guardrail plates are applied to construction sites, the guardrail plates often need to be assembled or disassembled, which affects the installation and disassembly efficiency of the guardrail plates. In addition, after the guardrail plates are installed, since the models of the guardrail plates are fixed, it is difficult to adjust their heights according to the needs of different construction sites, resulting in certain limitations in the use of the device. To sum up, the existing guardrail plates also have the following problems:

[0004] 1. The guardrail plates are assembled and connected by screws, and the installation efficiency is average; 2. It is difficult to adjust the height of the guardrail plates according to the needs of different construction sites, resulting in certain limitations in their use. Content of the Utility Model

Two support plates are installed at the front and rear upper parts of the support base respectively, a first guardrail plate is installed in the middle of the upper end of the support base, an adjusting device is installed at the upper end of the first guardrail plate, two reflective strips are installed at the left and right parts of the front end of the first guardrail plate respectively, and a warning device is installed at the upper part of the front end of the first guardrail plate.

[0008] Preferably, the adjusting device includes a second guardrail plate. A set of screw holes are provided in the left and right front parts of the second guardrail plate. Two mounting screws are installed in the left and right front parts of the first guardrail plate. An adjusting groove is provided at the upper end of the first guardrail plate. The second guardrail plate is installed on the upper end of the first guardrail plate through the mounting screws. By adjusting the protruding distance of the second guardrail plate on the first guardrail plate, after the second guardrail plate is adjusted to the appropriate height, the mounting screws can be screwed in for fixation, so that the height of the guardrail plate can be adjusted according to needs, improving the practicability of the device. Moreover, through the design of the reflective strip on the first guardrail plate, it is avoided that pedestrians are prone to rub against the guardrail plate at night, thereby improving the warning effect of the device.

[0009] Preferably, the warning device includes a mounting base and a mounting frame. Fixed grooves are provided in the left and upper right parts of the upper end of the mounting base. A warning sign is installed at the front end of the mounting frame. The mounting frame is installed on the upper end of the mounting base through the fixed grooves. The mounting base is installed on the upper front part of the first guardrail plate. The warning sign is installed on the mounting base through the mounting frame, which can not only further remind people that construction is in progress ahead, but also the mounting frame is clamped on the mounting base, which is convenient for replacing the warning sign.

[0010] Preferably, an installation groove is provided in the middle of the upper end of the support base. A number of anti-slip strips are installed at the lower end of the support base. The first guardrail plate is quickly installed on the support base through the installation groove, and then the first guardrail plate is limited and fixed by the support plate, further improving the stability of the first guardrail plate after installation. Moreover, the installation is carried out by a clamping method without the need to be fixed by screws, thereby improving the installation and disassembly efficiency of the first guardrail plate.

[0011] Preferably, the mounting screws correspond to the screw holes in the front and rear positions.

[0012] Preferably, a number of the anti-slip strips are equidistantly distributed at the lower end of the support base from left to right.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The first guardrail plate is quickly installed on the support base through the installation groove, and then the first guardrail plate is limited and fixed by the support plate, further improving the stability of the first guardrail plate after installation. Moreover, the installation is carried out by a clamping method without the need to be fixed by screws, thereby improving the installation and disassembly efficiency of the first guardrail plate.

[0015] 2. By loosening the mounting screws on the adjustment device, the protruding distance of the second guardrail plate on the first guardrail plate can be adjusted at this time. After the second guardrail plate is adjusted to the appropriate height, then screw in the mounting screws for fixation, so that the height of the guardrail plate can be adjusted according to needs, improving the practicability of the device. Moreover, through the design of the reflective strips on the first guardrail plate, it is avoided that pedestrians are prone to scrape against the guardrail plate at night, thereby improving the warning effect of the device. And each component of the device can be disassembled, which is convenient for carrying the device. At the same time, both the first guardrail plate and the second guardrail plate are hollow inside, reducing the weight of the guardrail plate to facilitate the installation or carrying of the device.

[0016] 3. The warning sign on the warning device is installed on the mounting seat through the mounting frame, which can not only further remind people that construction is in progress ahead, but also the mounting frame is clamped on the mounting seat, which is convenient for replacing the warning sign.
