Problems solved by technology

[0003]In order to solve the problem that the existing three-sided billboard does not have the light source and lighting function, the present invention provides a through-hole waterproof and dust-release three-sided billboard Ejector, the main body of the upper ejector rod of the three-sided billboard is hollow, and its exterior is made of engineering nylon, and a thick-walled metal tube is embedded inside to increase the strength of the upper ejector rod. Inside the metal tube, there is a three-sided billboard with light source and lighting functions. The conductive slip ring is equipped with a waterproof and dust-proof groove at the lower end. The waterproof and dust-releasing groove can effectively discharge water and prevent dust, and at the same time prolong the service life of the three-sided billboard and reduce the maintenance rate of the three-sided billboard.

Embodiment Construction

[0011] In the figure, a cylindrical thick-walled metal tube 2 is embedded in the top rod of the through-hole waterproof and dustproof billboard, and a conductive slip ring 4 is fitted inside the thick-walled metal tube 2. The upper part of the stator of the ring 4 is connected to the fixed end wire assembly 6 upwards, and the rotor is connected to the rotor end wire assembly 5 downwards, and the fixed end wire assembly 6 and the rotor end wire assembly 5 extend up and down along the inside of the metal tube 2, A nylon main body 1 is provided on the outside of the thick-walled metal through-tube 2, and a fixed slideway 7 is provided on the periphery of the nylon main body 1, and a waterproof and dustproof groove 3 with a concave groove is provided at the bottom of the nylon main body 1. When in use, the upper ejector rod is installed in the upper spring box 8, and a hollow pipe is provided inside the upper spring box 8 to facilitate the extension of the fixed-end wire assembly...

Abstract

The invention relates to an upper ejector rod of a through hole type waterproof and dustproof three-face-turned advertising board. A barrel-shaped thick-wall metal through pipe is embedded in the upper ejector rod of the through hole type waterproof and dustproof three-face-turned advertising board, a conductive sliding ring is arranged in the thick-wall metal through pipe in a matching mode, the upper portion of the stator of the conductive sliding ring is upwards communicated with a fixed end guide wire assembly, a rotor is downwards communicated with a rotor end guide wire assembly, the fixed end guide wire assembly and the rotor end guide wire assembly extend up and down along the interior of the metal through pipe, a nylon body is arranged outside the metal through hole, a fixed sliding rail is arranged on the periphery of the nylon body, and a waterproof and dustproof tank with concave grooves is formed in the lower portion of the nylon body. The interior of the upper ejector rod of the three-face-turned advertising board is hollow, the thick-wall metal pipe is embedded in the upper ejector rod, and strength is high. Due to the fact that the conductive sliding ring is arranged in the thick-wall metal through pipe, the wire winding problem due to the fact that a light source and lighting equipment are connected into the three-face-turned advertising board is solved, water and dust can be effectively prevented, meanwhile, the service life of the three-face-turned advertising board is prolonged, and the maintenance rate of the three-face-turned advertising board is reduced.

Description

technical field [0001] The invention relates to an upper ejector rod of a three-sided billboard, in particular to a through-hole waterproof and dustproof upper ejector rod for a three-sided billboard. Background technique [0002] With the development of society and the advancement of science and technology, in view of the fact that three-sided billboards have been accepted by people, especially the scarce advertising space resources are very expensive, print advertisements have been eliminated in scarce advertising spaces, and three-sided billboards are becoming more and more popular. In view of the wide application of the three-sided flip, the traditional three-sided billboard needs to be updated and brightened. Today, the LED three-sided flip billboard is quietly rising, and the current three-sided flip-up ejector is no longer available. To meet the needs of the new type of three-sided flip lighting. Contents of the invention [0003] In order to solve the problem that...
