Abstract

The invention relates to the technical field of traffic prompt, and discloses a traffic signal lamp for a tunnel entrance. The traffic signal lamp for the tunnel entrance comprises a support base; a support cylinder is fixedly connected to the top of the support base; a rack is glidingly connected to the inside surface of the support cylinder; a support rod is rotatably connected to the side surface of the support cylinder; a driving wheel positioned in the support cylinder fixedly sleeves one end of the support rod; and the outer teeth of the driving wheel are in meshed connection with the outer teeth of the rack. According to the traffic signal lamp for the tunnel entrance in the invention, due to matched use of the support cylinder and a fixed block, the stability of the rack while moving is improved; the problem that prompt to vehicles is influenced due to back and forth shaking of a prompt lamp because of back and forth shaking of the rack in a moving process can be avoided; by utilization of the action of a rocker, the area of the support rod is increased; the driving wheel is conveniently operated, so that the rack is driven to move; simultaneously, the height prompt of theprompt lamp is also conveniently carried out; and the problem that the prompt lamp cannot be adjusted to a proper position is prevented.

Description

technical field [0001] The invention relates to the technical field of traffic prompts, in particular to a traffic signal light used at the entrance of a tunnel. Background technique [0002] Traffic signal lights are signal lights for directing traffic operations. They are generally composed of red lights, green lights, and yellow lights. Pedestrian crossing signal lights, direction indicator lights, lane signal lights, flashing warning lights, road and railway level crossing signal lights. [0003] Because the light inside the tunnel is too dim compared to the outside world, and the driving space inside the tunnel is smaller than the outside driving space, it is necessary to set up signal lights outside the tunnel to remind passing vehicles. Most of the existing traffic lights at the entrance of the tunnel cannot According to the environment around the tunnel, adjust the height of the signal light, causing the signal light to be too high or too low, which is not conducive...
