Problems solved by technology

[0002] At present, signs are widely used in cities. Signs on urban roads are generally provided with support structures to prop up and fix signs. However, in tunnels, some tunnels are designed to be narrow 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, but they need The installation is cumbersome, the fixation is not reliable, and the use cost is high, so it is not suitable for promotion and use

Abstract

The invention discloses a safety tunnel sign plate device. The safety tunnel sign plate device comprises an upper base and a lower base, wherein a plate frame for supporting a sign plate is arranged at the bottom end of the lower base; two groups of fixing strips are arranged at the front surface end of the plate frame in up-and-down symmetry; a locking pin is arranged on the middle part of the upper end of the lower base; a sliding slot is formed in the locking pin; an accommodating groove is formed in the lower base at the lower end of the sliding slot; a straight rod inserting into the sliding slot and fixedly connected with the inner top wall of the sliding slot is arranged inside the accommodating groove; a positioning block is arranged on the straight rod; a first elastic component is wound on the straight rod at the lower end of the positioning block; locking grooves are symmetrically formed in the outer walls of the two sides of the upper end of the locking pin; a beveled part is arranged at the upper part of the locking pin. The safety tunnel sign plate device is simple in structure, relatively small in occupied area, convenient to detach and mount and firm in fixation, and is suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of LED street lamps, in particular to a safety 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 safety tunnel indicator device, which...
