Stable sign board device

Abstract

The invention discloses a stable sign board device which comprises a base, a combining rod and a sign board part. The left side of the base is internally provided with an inner spiral pattern trough. The upper inner wall and the lower inner wall at the right side of the inner spiral pattern trough are symmetrically provided with sliding troughs. One side, which is far from the inner spiral pattern trough, of the sliding trough is provided with an oblique hole. Each sliding trough is internally provided with a guiding rod. The guiding rod is connected with a sliding block in a slidable matching manner. The sliding block slidably matches the sliding trough. A first tension spring surrounds the guiding rod at the right side of the sliding block. One side, which is next to the inner spiral pattern trough, of the sliding block penetrates through the inner spiral pattern trough. A first through hole vertically penetrates through the sliding block. The first through hole is internally provided with a first accommodating trough at the central part. A first pressing block is slidably arranged in the first accommodating trough. A block is slidably connected in the first through hole. The stable sign board device has advantages of simple structure, high convenience in mounting, high stability, effective electric shock preventing function and effective safety improvement.

Description

technical field [0001] The invention relates to the technical field of safety signage, in particular to a stable signboard device. Background technique [0002] Safety signs can be seen everywhere in daily life, and they are mainly used for safety guidance. The safety signs in the prior art are generally fixed on the wall by screws when they are installed, so that they are electrically connected to the power supply part in the wall. In order to realize the power supply work, the installation process is time-consuming and labor-intensive, and the efficiency is low. At the same time, since no protective structure is set between the safety sign and the power supply part in the wall, when the safety sign fails and needs to be repaired and maintained, it is extremely difficult. It is easy to touch the conductive parts in the power supply unit and cause electric shock accidents, which poses a great safety hazard. Contents of the invention [0003] The technical problem to be so...
