Technical Field
[0001] This utility model relates to the field of luminous advertising font technology, specifically a waterproof luminous advertising font structure. Background Technology
[0002] Illuminated signs are illuminated signage made using LEDs as the light source, consisting of a letter shell, faceplate, and base plate. Illuminated signs offer rich colors and personalization, making the signage more user-friendly and playing an important promotional role for businesses, shops, and exhibitions. The production of illuminated advertising signs mainly includes design and layout, material cutting, welding and assembly, light source installation, and debugging. Commonly used materials include acrylic sheets, metal sheets (such as stainless steel and aluminum sheets), and LED modules. Tools include laser cutters and welding machines.
[0003] In existing illuminated advertising letter structures, the contact point between the light-transmitting panel and the side panel of the advertising letter is only connected by adhesive, resulting in a poor sealing effect. This allows rainwater to easily seep into the letter from the joint, which can easily damage the advertising letter. In addition, the wiring holes on the base plate of existing illuminated advertising letter lack sealing devices, allowing rainwater to flow into the letter along the wires and damage the internal circuitry. Utility Model Content
[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a waterproof luminous advertising font structure. Through the design of a sealing strip, a side adhesive groove, and a bottom adhesive groove, transparent sealant is injected into the side adhesive groove at the contact point between the light-transmitting panel and the side panel, sealing the light-transmitting panel to the sealing strip. The adhesive injected into the bottom adhesive groove of the sealing strip ensures a tight bond between the sealing strip and the inner side of the side panel, thereby preventing rainwater from seeping into the font through the gap between the light-transmitting panel and the side panel, thus avoiding damage to the font. This effectively solves the problems in the background technology.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof luminous advertising font structure, including a base plate, a side plate provided on one side of the base plate, a sealing strip provided on the inner side of the side plate, a bottom adhesive groove provided on the side of the sealing strip that contacts the side plate, a side adhesive groove provided on the other side of the sealing strip, a sealing threaded sleeve passing through an opening in the base plate, a threaded bend integrally formed at one end of the sealing threaded sleeve, and a limiting protrusion integrally formed inside the bottom adhesive groove.
[0006] Furthermore, a weld is provided at the contact position between the side plate and the bottom plate, and a light-transmitting panel is installed at the angle between the side plate and the sealing strip.
[0007] Furthermore, the side plate is welded to the bottom plate, the end contact position of the side plate is welded together, and the sealing strip is glued to the side plate.
[0008] Furthermore, the bottom adhesive tank is filled with sealant, and the side adhesive tank is filled with transparent sealant.
[0009] Furthermore, the sealing strip is connected to the light-transmitting panel through the transparent sealant in the side adhesive groove, and the sealing thread sleeve is bonded to the base plate.
[0010] Furthermore, a rain guide plate is fixedly welded to the side of the base plate away from the side plate, and the rain guide plate is inclined upward at a 60-degree angle to the base plate.
[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of a sealing strip, a side adhesive groove, and a bottom adhesive groove, allows the light-transmitting panel to be sealed and bonded to the sealing strip at the contact point between the light-transmitting panel and the side panel by injecting transparent sealant into the side adhesive groove. The adhesive injected into the bottom adhesive groove of the sealing strip can tightly bond the sealing strip to the inner side of the side panel, thereby preventing rainwater from seeping into the font from the gap between the light-transmitting panel and the side panel and avoiding damage to the font.
[0012] 2. This utility model uses a sealed wire-threading sleeve and a wire-threading bend. The sealed wire-threading sleeve is installed on the wire-threading hole of the base plate, and then the power cord passes through the wire-threading bend and enters the inside of the advertising font. When rainwater drips onto the power cord, the downward-facing wire-threading bend prevents the rainwater from flowing upward along the power cord and thus from flowing into the advertising font, avoiding damage to the circuit module.
