Technical Field
[0001] This utility model relates to the field of electro-optical sign technology, specifically a new type of convenient and detachable tunnel electro-optical sign. Background Technology
[0002] Electro-optical signs are typically lightbox structures, with internal light strips illuminating the front and back covers representing the signs. This method allows workers to find the information corresponding to the signs in dark tunnels.
[0003] In existing technologies, due to the lifespan of the light source, tunnel electro-optical signs stop illuminating after a certain number of years. Traditional maintenance methods involve replacing the entire tunnel electro-optical sign box or disassembling and reassembling the sign at height to replace the internal light strips. This process is time-consuming for workers and increases operating costs. Utility Model Content
[0004] The purpose of this utility model is to provide a new type of convenient and detachable tunnel electro-optical sign to solve the problem that the above-mentioned background technology requires workers to spend a long time to disassemble and install, which also increases the cost of use. By setting up a buckle component, the effect of quick replacement and disassembly can be effectively achieved.
[0005] To solve the above technical problems, this utility model provides the following technical solution: a novel convenient and detachable tunnel electro-optical sign, including a light box, the inner side of which is provided with several sets of buckle components, and the buckle components are used to restrict the lighting structure; the front of the left end of the light box is provided with a splicing component, and the splicing component is used to flexibly disassemble the front structure to assist in replacement.
[0006] The buckle assembly includes a fixing buckle, which is fixed to the inner wall of the light box. A torsion spring shaft is provided on the inner side of the end of the fixing buckle, and a flip buckle is movably provided on the front side of the torsion spring shaft.
[0007] The splicing assembly includes a fixing plate, and a flip bracket is movably provided on the front of the fixing plate. Two sets of splicing blocks are installed on the front of the flip bracket, and a lamp cover is spliced on the front of the flip bracket. Torsion spring plates are provided on the front of the upper and lower ends of the flip bracket, and the torsion spring plates are located on the front of the lamp cover.
[0008] Preferably, two sets of fixed brackets are installed on the left side of the light box, and two sets of magnetic blocks are embedded inside the right end of the light box.
[0009] Preferably, a connector is installed at the bottom inside the light box, and connecting wires are installed on both sides of the connector. A socket is installed at the left end of the connecting wires, and a plug is spliced on the top of the socket.
[0010] Preferably, a light strip is installed on the top of the plug, and the light strip is located inside the flip buckle and the fixing buckle, and the front of the flip buckle is provided with anti-slip texture.
[0011] Preferably, a fixing sleeve is installed on the right side of the fixing plate, and the fixing sleeve is located outside the fixing bracket. A bolt is installed between the fixing sleeve and the fixing bracket. A flipping shaft is provided in the middle of the flipping bracket and the fixing sleeve. Limiting blocks are installed on the front of the upper and lower ends of the flipping bracket, and the limiting blocks are located outside the torsion spring plate.
[0012] Preferably, a limiting plate is installed at the end of the torsion spring plate, and a torsion spring column is provided in the middle of the limiting plate. A push-pull insert plate is provided on the inner side of the upper torsion spring plate, and a slot is provided on the inner side of the lower torsion spring plate.
[0013] Preferably, the left end of the lamp cover has four sets of splicing grooves on the front, and the splicing grooves are located on the outside of the splicing block. The center of the lamp cover has a pattern, and the center of the right end of the lamp cover has a metal plate installed, which contacts the magnetic block.
[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0015] 1. This utility model uses a buckle assembly to provide an installation position for the front structure. The torsion spring shaft assists the flip buckle on the front for flipping adjustment. The torsion spring structure can apply a flipping force to keep the end of the flip buckle in contact with the inner wall of the light box. The fixed buckle and the flip buckle can clamp and restrict a part of the light strip. When disassembling, the light strip can be pulled out for replacement by controlling the flip buckle to open, which effectively shortens the replacement time and reduces costs.
[0016] 2. This utility model addresses the issue of inconsistent light cover structures in existing photoelectric signs, where the information on the light cover needs to be updated simultaneously when the lightbox position is changed, or disassembly and installation can be time-consuming when damaged. The installation of a fixing plate and a flip bracket assists in adjusting the angle of the front splicing component. The splicing block can then be combined with the splicing slot on the light cover. After assembly, the torsion spring plate is controlled to flip under the action of the internal torsion spring. After flipping, it will be in a horizontal position due to the obstruction of the limiting block. The flip bracket and torsion spring plate can restrict the light cover. During disassembly, controlling the torsion spring plate to flip vertically and then pushing the push-pull plate into the inner side of the slot allows for easy replacement of the light cover. The splicing component facilitates convenient disassembly and installation. Attached Figure Description
