Description

Technical Field

[0001] The utility model belongs to the technical field of lighting lamps, and particularly relates to an assembled tunnel lighting lamp. Background Art

[0002] Tunnel lights are special lamps used for tunnel lighting to solve the "black hole effect" or "white hole effect" caused by sudden changes in brightness when vehicles enter or exit tunnels. Tunnels are special sections of high-grade highways. When vehicles enter, pass through and exit tunnels, a series of visual problems will occur. In order to adapt to the changes in vision, additional electro-optical lighting is required.

[0003] Most of the existing tunnel lighting lamps are installed by hoisting. When installing the lighting lamp, it is necessary to install the lamp holder, and then use multiple screws to fasten the light strip on the lamp holder through the installation screws, and finally install the lampshade, which causes inconvenience in installation. Therefore, we propose an assembled tunnel lighting lamp to solve the above problems. Utility Model Content

[0004] The utility model aims to provide an assembled tunnel lighting lamp, which is easy to install, thereby improving the installation convenience, so as to solve the above-mentioned background technical problems.

[0006] Preferably, guide blocks are fixedly connected to both sides of the lamp holder surface, and the inner surface of the lamp tube is provided with a guide groove adapted to slide with the guide blocks, and the bottom end surface of the guide groove passes through the bottom of the lamp tube.

[0007] Preferably, there are multiple slide grooves, and the multiple slide grooves are arc-shaped.

[0008] Preferably, a mounting block is fixedly connected to the surface of the lamp tube in an annular shape, and a threaded mounting hole is provided inside the mounting block.

[0009] Preferably, the threaded rotating rod passes through the lamp holder and is located on the inner surface of the bearing seat, and the bearing seat is embedded and fixed inside the axis of the lamp holder.

[0010] The beneficial effects of the utility model are:

[0011] 1. When the utility model needs to be installed, it is only necessary to push the lamp holder into the inner surface of the lamp tube, and the lamp holder slides on the inner surface of the lamp tube. When it slides to the appropriate position, the threaded rotating rod is turned clockwise by hand, and the threaded rotating rod drives the turntable to rotate. The rotation of the turntable drives the slide groove to produce displacement deviation, thereby driving the slide post to slide on the inner surface of the slide groove. The sliding of the slide post drives the block to slide on the inner surface of the guide seat, so that the block is inserted into the corresponding slot. After the insertion is completed, the surface of the threaded rotating rod is tightened by tightening the nut, so as to prevent the threaded rotating rod from rotating by itself. Finally, the lampshade is installed by screws. By setting the above structure, convenient installation is achieved and the purpose of improving installation convenience is achieved;

[0012] 2. The utility model provides a guide block to slide on the inner surface of the guide groove to guide and limit the lamp holder when it slides up and down, thereby avoiding sliding deviation of the lamp holder;

[0013] 3. The utility model can facilitate the installation of the lamp tube by providing the threaded mounting hole provided by the mounting block, so that the lamp tube can be better connected with the external connection object;

[0014] 4. The utility model sets a threaded rotating rod that passes through the lamp holder and is located on the inner surface of the bearing seat, and the bearing seat is embedded and fixed inside the axis of the lamp holder, so as to avoid the bearing seat protruding from the bottom end surface of the lamp holder and affecting the close contact between the fastening nut and the lamp holder.
