Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of road construction, in particular to a road barrier for road construction. BACKGROUND

[0002] During road construction, a road barrier needs to be set up on the construction section. The road barrier is an obstacle that blocks road traffic and can be a barrier used as a fence during road repair.

[0003] However, if the road barrier is too light, it can be moved at will or its position can be offset by collision. If the road barrier is too heavy, it is not easy to carry and use, and the reflector plate is not easy to adjust. Other shielding objects need to be used to shield the reflector plate during the day, which makes the operation more troublesome.

[0004] The existing patent (publication number: CN2192808552U) is a road barrier for road construction, which relates to the technical field of road construction. The utility model discloses a base, the middle part of the base is fixed with a cylinder, two symmetrical through grooves are formed on one side of the base, two symmetrical first sliding grooves and second sliding grooves are formed on the circumferential side of the cylinder. The utility model drives the universal wheel to extend or retract into the through groove, which can drive the road barrier to move or fix. A solar panel is arranged on the upper end of the cylinder to make full use of renewable resources, which is more energy-saving and environmentally friendly. The annular column drives multiple reflector plates to slide under the solar panel. During the day, the multiple reflector plates are attached to the lower side of the solar panel, effectively reducing the strong reflection of the multiple reflector plates, which affects the route of the driver. At night, the multiple reflector plates form a conical cylinder structure to reflect the driver, reduce the risk of driving, effectively optimize and improve the use effect of the road barrier, and the operation is convenient.

[0005] However, the above technical solution still has some shortcomings. In the use process, the base and barrel outside the existing road barrier cannot be folded and contracted, so the volume of the road barrier cannot be reduced. The relatively large volume needs to occupy a large amount of space, so that a large space needs to be occupied during transportation and storage, which makes the transportation and storage process very inconvenient, affects the convenience of the road barrier in actual use, and wastes a lot of storage space.

[0038] By rotating the threaded rod 102, the threaded rod 102 drives the first slider 103 to slide, the first slider 103 drives the two groups of first rotating rods 104 to rotate, thereby pushing the two groups of baffles 106 to expand to both sides, and drives the second rotating rod 105 to rotate. In the process of the first slider 103 sliding upwards, the first slider 103 pushes the solar panel 303 through the pushing rod 304, so that the solar panel 303 drives the third slider 302 to slide upwards on the inner wall of the guide rail 301.

At this time, the rubber airbag 210 is pushed and expanded by the air. When the impact ends, the rubber airbag 210 is contracted under the action of its own elasticity, so that the air in the rubber airbag 210 returns to the sleeve 207, thereby pushing the piston 208 to reset. The piston 208 pushes the jacks 206 to reset through the connecting rods 209, so that the jacks 206 push the two groups of second sliders 203 to slide reversely on the outer wall of the guide rod 202 to reset. The second slider 203 resets the guard plate 205 through the supporting rod 204.

[0040] By pushing the push piece 406, the push piece 406 drives the push rod 405 to slide inside the base 401, and the push rod 405 slides in the process, the push pin 403 slides to the inside of the base 401, so that the push pin 403 slides out of the inside of the limiting groove 404 and compresses the reset spring 407, at this time, the support leg 402 can be pushed to slide on the inner wall of the base 401, so as to adjust the height and placement state of the whole roadblock, then release the push piece 406, so that the reset spring 407 pushes the push pin 403 to slide reversely and insert into the inside of another set of limiting grooves 404, and the push pin 403 pushes the push rod 405 to reset.
