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

[0002] Highway signs have functions such as indicating routes and marking geographic locations, and are often fixed on poles. Existing highway signs are fixed to poles by means of a semicircular clamp that is tightened against the outer wall of the pole. However, this method can only fix the sign to the pole horizontally or vertically, that is, the semicircular clamp cannot be used for both horizontal and vertical fixation of the sign, which reduces the applicability of the fastening device.

[0003] After the clamping ring is put on the outer wall of the benchmark, the two ends of the clamping ring are fixed to the back of the sign by bolts to fix the sign relative to the benchmark. Since the semicircular clamping ring only has a single fastening function and the bolt connection on the sign is pre-set, the protruding length of the sign relative to one side of the benchmark cannot be adjusted after the sign is fixed, and the position of the sign cannot be adaptively adjusted according to actual environmental conditions.

[0004] To solve the above problems, we propose a highway sign fastening device. Utility Model Content
