Description

Technical Field

[0001] The utility model relates to the technical field of construction warning signs, and more specifically, to a municipal road construction warning sign. Background Art

[0002] Municipal road construction often occupies part of the road space, resulting in changes in traffic flow and restricted traffic conditions. In this case, if there are no clear warning signs, pedestrians and vehicles may mistakenly enter the construction area, causing safety accidents, resulting in casualties and property losses. With the acceleration of urbanization, the construction and maintenance of municipal roads are becoming more and more frequent. During road construction, in order to ensure the safety of construction workers and passing pedestrians and vehicles, setting up construction warning signs has become an indispensable measure. Existing road construction warning signs usually consist of an aluminum plate and a support frame, with reflective fonts pasted on the outer surfaces of both sides of the aluminum plate to remind passing vehicles and pedestrians. However, most of the support frames and aluminum plates of this type of warning signs are fixedly installed, resulting in the warning signs occupying a large space during transportation, which reduces the utilization rate of transportation space to a certain extent, thereby increasing the transportation cost of the warning signs. In order to solve the shortcomings of the existing technology, we propose a municipal road construction warning sign. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a municipal road construction warning sign to solve the problem that the warning sign occupies a large space during transportation, which reduces the utilization rate of the transportation space to a certain extent, thereby increasing the transportation cost of the warning sign.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a municipal road construction warning sign, comprising a sign body and a light-emitting board, a support frame assembly is arranged on the lower side of the sign body, a light-emitting assembly is arranged in the inner cavity of the sign body, and transparent blocks are fixedly installed on the left and right outer surfaces of the sign body;

[0005] The support frame assembly includes a motor, a threaded screw is fixedly installed on the outer surface of the output end of the motor, the outer wall of the threaded screw is threadedly connected to an H-shaped slider, the inner walls on both sides of the H-shaped slider are rotatably connected to two support plates, one side of the two support plates is rotatably connected to two base plates, and limiting columns are arranged on both sides of the H-shaped slider.

[0006] The motor is fixedly mounted on the upper inner wall of the card body, the H-shaped slider slides on the side inner cavity surface of the card body, and the limit column is rotatably connected to the lower inner wall of the card body.

[0007] Wherein, the light-emitting component includes a T-shaped rod, a trapezoidal block is fixedly installed on the outer surface of the upper end of the T-shaped rod, two wedge blocks are slidably connected to the outer surfaces of the left and right sides of the trapezoidal block, and the inclined surfaces of the two wedge blocks are provided with sliding grooves, two electrode blocks are arranged on the outer surface of one side of the wedge block, two conductor blocks are arranged on one side of the two wedge blocks, and one side surface of the two conductor blocks is electrically connected to a light-emitting bulb, a fixed block is welded on the lower outer surface of the two wedge blocks, and a spring is fixedly installed on the inner wall of one side of the fixed block, the cross bar of the T-shaped rod is rotatably connected between the two support plates, and the vertical bar of the T-shaped rod slides in the middle of the inner wall of the card body, the two conductor blocks are fixedly installed on the two side surfaces of the inner cavity of the card body, the two wedge blocks slide at the bottom of the inner cavity of the card body, the fixed block is slidably connected to the lower inner wall of the card body, and the outer surface of one end of the spring is fixedly installed on the inner surface.

[0008] When the two support plates are fully unfolded, the two bottom plates form an obtuse angle of a certain angle on the same vertical plane, and when the two support plates move upward, the outer surfaces of the two support plates slide on the outer walls of the limiting columns.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model provides a support frame assembly including a motor. The motor is started to drive the threaded screw to rotate. The threaded screw rotates to drive the H-shaped slider to slide on the inner wall of one side of the sign body, driving the two support plates to move upward. Through the limit column, the two support plates rotate on the inner side of the H-shaped slider to approach each other, thereby driving the two bottom plates to rotate close to the support plates. By using the above structure, the motor is started to drive the two H-shaped sliders to slide on the inner wall of one side of the sign body, so that the extension, opening, contraction and merging of the support plates are realized, reducing the occupied space of the warning sign, thereby improving the utilization rate of the transportation space and reducing the transportation cost.

[0012] The utility model provides a light-emitting assembly, including a T-rod. When the starting motor extends out of the support plate, the T-rod moves downward to drive the trapezoidal block to slide between the two wedge-shaped blocks, so that the positive and negative electrode blocks on one side of the wedge-shaped block fit with the positive and negative wedge-shaped blocks on one side of the conductor block. At this time, the light-emitting bulb works to emit light, and then the light passes through the transparent block from the inside of the sign body. By utilizing the above structure, the starting motor drives the wedge-shaped block to approach the conductor block, so that the light-emitting bulb is powered on and works, and the generated light is diverged through the transparent block, so that the warning sign is convenient to use at night, and the practicality of the warning sign is greatly improved.

[0024] By starting the motor 21 to drive the threaded screw 22 to rotate, the rotation of the threaded screw 22 drives the H-shaped slider 23 to slide on the inner wall of one side of the sign body 1, driving the two support plates 24 to move upward, passing through the limiting column 26, so that the two support plates 24 rotate on the inner side of the H-shaped slider 23 and approach each other, thereby driving the two bottom plates 25 to rotate close to the support plates 24.

[0025] The light-emitting assembly 3 comprises a T-shaped rod 31, a trapezoidal block 32 is fixedly mounted on the outer surface of the upper end of the T-shaped rod 31, two wedge-shaped blocks 33 are slidably connected to the outer surfaces of the left and right sides of the trapezoidal block 32, two electrode blocks 35 are arranged on the outer surface of one side of the wedge-shaped block 33, a slide groove 34 is provided on the inclined surface of the two wedge-shaped blocks 33, two conductor blocks 36 are arranged on one side of the two wedge-shaped blocks 33, and a light-emitting bulb 37 is electrically connected to the surface of one side of the two conductor blocks 36, a fixing block 38 is welded on the outer surface of the lower side of the two wedge-shaped blocks 33, and a spring 39 is fixedly mounted on the inner wall of one side of the fixing block 38, the cross bar of the T-shaped rod 31 is rotatably connected between the two support plates 24, the vertical bar of the T-shaped rod 31 slides in the middle of the inner wall of the card body 1, the two conductor blocks 36 are fixedly mounted on the two side surfaces of the inner cavity of the card body 1, the two wedge-shaped blocks 33 slide at the bottom of the inner cavity of the card body 1, the fixing block 38 is slidably connected to the lower inner wall of the card body 1, and the outer surface of one end of the spring 39 is fixedly mounted on the inner surface;
