A tunnel signage device

Abstract

The invention discloses a tunnel direction board device comprising an upper base body and a lower base body. A board rack used for supporting the direction board is arranged on the bottom end of the lower base body, two sets of fixed strips are symmetrically arranged on the front surface of the board rack in the vertical direction, a lock pin is arranged on the central part of the upper end of the lower base body, a slip groove is arranged in the lower end of the lock pin, a placing groove is arranged in the lower base body under the slip groove, a straight rod which penetrates the slip groove and is fixedly connected with the inner upper wall of the slip groove is arranged in the placing groove, the straight rod is provided with a locating piece, the part of the straight rod under the locating piece is wound by a first elastic component, locking grooves are symmetrically arranged in outer walls at two sides of the upper end of the lock pin, and the upper part of the lock pin is provided with a beveling part. The tunnel direction board device is simple in structure, small in occupied area and convenient to dismount and assemble, and can be fixed firmly, and is suitable for promotion and application.

Description

technical field [0001] The invention relates to the technical field of LED street lamps, in particular to a tunnel indicator device. Background technique [0002] At present, signs are widely used in cities. Signs on urban roads are generally provided with support structures to support and fix signs. However, in tunnels, some tunnels are designed to be narrow in order to ensure safe passage, which cannot meet the requirements of the setting. Therefore, fixing the signs in the tunnel without a support structure is an important guarantee for the safe passage of vehicles in the tunnel. In the prior art, there are many sign devices that do not need support. The installation is relatively cumbersome, the fixation is relatively unreliable, and the use cost is relatively high, so it is not suitable for popularization and use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tunnel indicator device, which can solve the...
