They cannot be directly stored, which makes it inconvenient to transport the fences, thereby reducing the practicality of the road fences.

[0005] In order to achieve the above utility model purpose, the technical solution adopted by the utility model is:

[0006] A lifting fence for road construction comprises a base, a top cover is arranged above the base, mounting grooves are arranged on the sides of the base and the top cover close to each other, a plurality of evenly distributed scissor-type connecting rods are arranged between the base and the top cover, and a driving assembly is arranged at the bottom of one of the scissor-type connecting rods.

[0007] Furthermore, a plurality of evenly distributed connecting chains are provided between every two adjacent scissor-type connecting rods.

[0008] Furthermore, the connecting rods at the bottom and the right end of the top of the scissor-type connecting rod are respectively hinged to the mounting groove, and the connecting rods at the bottom and the left end of the top of the scissor-type connecting rod are respectively slidably connected to the mounting groove.

[0009] Furthermore, the driving assembly includes a motor fixedly installed in the base, a lead screw is fixedly connected to the output shaft of the motor, a connecting block is hinged on the lead screw, and the connecting block is hinged to the connecting rod on the left side of the bottom of the scissor-type connecting rod.

[0010] Furthermore, a snap-fit ​​movable portion is provided on the base, and a snap-fit ​​fixed portion is provided on the top cover, and the snap-fit ​​movable portion and the snap-fit ​​fixed portion can be snapped together.

[0011] Furthermore, a groove is provided at the bottom of the base, and a bracket is hinged in the groove.

[0012] The beneficial effects of the utility model are:

[0013] The utility model discloses a lifting fence for road construction, which is convenient for adjusting the height of the fence through the arranged driving components and scissor-type connecting rods. The fence is convenient for storage and transportation when not in use, and has good practicality. BRIEF DESCRIPTION OF THE DRAWINGS
