Description

Technical Field

[0001] The utility model relates to the technical field of signboards, in particular to a road traffic signboard. Background Art

[0002] Road traffic signs are signs printed with road traffic signs. They are usually made of aluminum alloy plates with text or symbols printed on the surface. They are used to manage traffic and indicate driving directions to ensure smooth roads and driving safety. Common road traffic signs can be divided into prohibition signs, instruction signs, road construction safety signs and speed limit signs.

[0003] Among them, road construction safety signs are generally welded into a frame with angle steel, and the signboard is fixed and installed on the top of the front side of the frame with rivets. In order to prevent the signboard from being caught by the wind, a support leg is usually set to tilt the signboard to improve stability. However, the length of the signboard support leg is fixed, so the tilt angle of the signboard is fixed. On ramps or uneven ground, the signboard is unstable and easy to fall over. In addition, the tilted signboard is not conducive to observation by vehicles in the distance. At night, the tilted signboard will cause the reflection of the signboard to not be fully observed by the driver, affecting road safety. Utility Model Content

[0029] Embodiment 1:

[0030] See also Figure 1-5 The utility model describes the above technical solution in detail through the following embodiments:

[0031] A road traffic sign, comprising:

[0032] The identification plate assembly 1 includes an identification plate 12 , a rotating frame 11 is provided on the back of the identification plate 12 , and the rotating frame 11 is rotatably installed between the mounting frames 15 through rotating bolts 13 , and the bottom end of the mounting frame 15 is connected to the supporting device 3 through the rotating device 2 .

[0033] The signboard 12 is made of aluminum alloy and is used for printing traffic signs. The rotating frame 11 and the signboard 12 can be fixedly connected by rivets or screws.

[0034] Fixed cross beams 16 are welded at the upper and lower ends of the mounting frame 15 , and the fixed cross beams 16 are used to support the mounting frame 15 .

[0035] The rotating bolt 13 is located at the upper middle part of the left and right sides of the rotating frame 11 . The rotating bolt 13 is welded to the rotating frame 11 . The head of the rotating bolt 13 passes through the mounting frame 15 and is threadedly connected with a knob 14 .

[0036] Since the knob 14 is threadedly connected to the rotating bolt 13, the knob 14 can be turned to move along the axis of the rotating bolt 13. Since the rotating bolt 13 is located in the upper middle part of the rotating frame 11, the center of the rotating frame 11 is located below the axis of the rotating bolt 13. When the knob 14 is loosened, the rotating frame 11 can be rotated by the rotating bolt 13, and the rotating frame 11 remains in a vertical state. When the knob 14 is tightened, the end face of the knob 14 abuts against the side of the mounting frame 15, which can limit the rotation of the rotating frame 11 and achieve the fixation of the rotating frame 11.

[0037] After loosening the knob 14 , an external force may be applied to the rotating frame 11 to drive the rotating frame 11 to rotate around the rotating bolt 13 , and the angle of the rotating frame 11 may be manually adjusted, thereby adjusting the angle of the identification plate 12 .

[0038] The rotating device 2 includes a rotating sleeve 21 , in which a guide column 25 is arranged. The guide column 25 is rotatably connected to the rotating sleeve 21 through a limiting assembly. The supporting device 3 is located at the bottom end of the guide column 25 .

[0039] The rotating sleeve 21 is welded and mounted on the center of the bottom end of the mounting frame 15. The rotating sleeve 21 is a hollow metal cylinder.

[0040] The limiting assembly includes a guide groove 23 , which is located in the middle of the rotating sleeve 21 . A limiting bolt 24 is slidably provided at the guide groove 23 . The limiting bolt 24 passes through the guide groove 23 and is threadedly connected to the guide column 25 .

[0041] The guide groove 23 is U-shaped, and the angle between the two vertical grooves of the guide groove 23 is 90°. The guide groove 23 is used to limit the moving track of the guide column 25. Due to the presence of the limit bolt 24, the guide column 25 can only move along the track of the guide groove 23.

[0042] A return spring 22 is disposed at the top of the guide column 25 , and the top of the return spring 22 contacts the inner top surface of the rotating sleeve 21 .

[0043] The bottom end of the return spring 22 abuts against the top end of the guide post 25 . Under the elastic force of the return spring 22 , the guide post 25 tends to separate from the rotating sleeve 21 , so that the limiting bolt 24 is located at the lowest point of the guide groove 23 .

[0044] Applying an upward force to the guide column 25 can drive the guide column 25 to move upward, thereby compressing the reset spring 22, and then driving the limit bolt 24 to move upward along the guide groove 23. When the limit bolt 24 moves to the transverse groove of the guide groove 23, the guide column 25 is rotated to drive the guide column 25 to rotate, thereby driving the limit bolt 24 to rotate along the guide groove 23. When the limit bolt 24 rotates 90°, the external force applied to the guide column 25 is removed. At this time, under the elastic force of the reset spring 22, the guide column 25 and the limit bolt 24 can move downward along the guide groove 23.

[0045] The supporting device 3 includes a main leg 31 , a moving component is provided at the bottom end of the main leg 31 , and the moving component is used to move the device. The middle part of the main leg 31 is connected to an adjustment component through an auxiliary leg 35 , and the adjustment component is used to adjust the inclination angle of the main leg 31 .

[0046] The top of the main leg 31 is welded to the bottom of the guide column 25, and the axes of the guide column 25 and the main leg 31 coincide. The auxiliary leg 35 is welded and installed in the middle of the main leg 31, and the main leg 31 and the auxiliary leg 35 are perpendicular.

[0047] The adjustment assembly includes an adjustment sleeve 36 , which is welded and installed at the rear end of the auxiliary leg 35 , and an adjustment rod 37 is arranged inside the adjustment sleeve 36 .

[0048] There is an angle of 15° between the axis of the adjusting sleeve 36 and the axis of the auxiliary leg 35. When the adjusting sleeve 36 is kept in a vertical state, there is an angle of 75° between the auxiliary leg 35 and the vertical direction, so that there is an angle of 15° between the axis of the main leg 31 and the vertical direction, and then there is an angle of 15° between the mounting frame 15 and the vertical direction, and the center of gravity of the mounting frame 15 is located between the adjusting sleeve 36 and the main leg 31.

[0049] The moving assembly includes a connecting plate 32, which is welded and installed at the bottom end of the main support leg 31. Two universal wheels 33 are fixed side by side by bolts under the connecting plate 32, and each universal wheel 33 is rotatably connected to a brake 34 through a pin shaft.

[0050] When the auxiliary legs 35 are stored under the fixed beam 16, the main legs 31 are in a vertical state. At this time, the sign assembly 1 is in a vertical state. The universal wheels 33 are located on the left and right sides of the fixed beam 16, which can provide support for the sign assembly 1 and facilitate the movement of the device.

[0051] When the auxiliary legs 35 are opened, the identification plate assembly 1 is tilted toward the adjustment sleeve 36. At this time, the brake 34 is turned downward, and the brake 34 abuts against the roller of the universal wheel 33 to limit the rotation of the roller of the universal wheel 33, thereby fixing the device.

[0052] The adjusting rod 37 includes a screw rod 371 , which is threadedly connected to the adjusting sleeve 36 , a positioning cone 372 is welded to the bottom end of the screw rod 371 , and a limiting ring 373 is clamped to the top of the screw rod 371 .

[0053] The positioning cone 372 is used to contact the ground and provide a fulcrum. Rotating the limit ring 373 can drive the screw 371 to rotate. Since the screw 371 is threadedly connected to the adjustment sleeve 36, the screw 371 can be driven to move along the axis of the adjustment sleeve 36, thereby adjusting the height of the adjustment sleeve 36. The change in the height of the adjustment sleeve 36 can change the angle between the auxiliary support leg 35 and the vertical direction, thereby changing the angle between the main support leg 31 and the vertical direction, and then changing the angle between the mounting frame 15 and the vertical direction.

[0054] When using the device in this embodiment, the operator pushes the mounting frame 15 and uses the universal wheels 33 to push the device to a suitable position.

[0055] Hold the auxiliary support leg 35 and the main support leg 31 and push upward to drive the guide column 25 and the limiting bolt 24 to slide upward along the guide groove 23 until the limiting bolt 24 slides to the transverse groove of the guide groove 23.

[0056] The auxiliary leg 35 is rotated, thereby driving the guide column 25 and the limiting bolt 24 to rotate along the guide groove 23. When the limiting bolt 24 rotates 90°, the external force applied to the auxiliary leg 35 and the main leg 31 is removed. At this time, under the elastic force of the return spring 22, the guide column 25 and the limiting bolt 24 can move downward along the guide groove 23, completing the deployment of the auxiliary leg 35.

[0057] The limiting ring 373 is rotated to drive the screw rod 371 to move along the axis direction of the adjusting sleeve 36, thereby adjusting the angle between the mounting frame 15 and the vertical direction to ensure that the center of gravity of the mounting frame 15 is located between the main leg 31 and the adjusting rod 37.

[0058] The brake 34 is rotated downward so that the brake 34 and the roller of the universal wheel 33 are counteracted to limit the rotation of the roller of the universal wheel 33.

[0059] The knob 14 is loosened, and under the action of gravity, the rotating frame 11 and the identification plate 12 rotate downward to a vertical state, and an external force is applied to the rotating frame 11 to fine-tune the angle of the rotating frame 11 .

[0060] After the rotating frame 11 is rotated to a suitable angle, the knob 14 is tightened to fix the angle of the rotating frame 11 .

[0061] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
