Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] refer to Figure 1-4 The structure shown is a quick-assembly and disassembly LED light box, including an aluminum alloy frame 101, with a chrome-plated carbon steel panel 102 inside the aluminum alloy frame 101; an aluminum alloy hanging plate 103 is provided on the front end of the chrome-plated carbon steel panel 102; a hook hole 104 is provided inside the aluminum alloy hanging plate 103, and the hook hole 104 is integrally formed with the aluminum alloy hanging plate 103, and the hook hole 104 passes through the aluminum alloy hanging plate 103 and the chrome-plated carbon steel panel 102 from front to back; a galvanized steel back plate is provided at the rear end of the aluminum alloy frame 101. 201; A hanging nail 203 is fixedly installed on the front end of the galvanized steel back plate 201, and the hanging nail 203 is hooked to the hook hole 104; LED light strip 105 is installed between the aluminum alloy hanging plates 103; a rubber anti-slip pad 108 is installed at the rear end of the LED light strip 105; a magnetic strip 109 is installed on the rear end of the rubber anti-slip pad 108, and the magnetic strip 109 is magnetically connected to the chrome-plated carbon steel panel 102; an acrylic light box 301 is installed at the front of the aluminum alloy frame 101; a magnetic inner frame 304 is installed at the rear end of the acrylic light box 301.

[0017] First, assemble the main frame: weld the aluminum alloy frame 101 to the chrome-plated carbon steel panel 102 into one piece, and then weld the aluminum alloy hanging plate 103 to the front end of the chrome-plated carbon steel panel 102 to form the main frame of the light box. Install internal light-emitting components: embed the magnet strip 109 into the rubber anti-slip pad 108 and fix it to the rear end face of the LED light strip 105. Then, through the magnetic attraction between the magnet strip 109 and the chrome-plated carbon steel panel 102, fix the LED light strip 105 between the aluminum alloy hanging plate 103. At the same time, the rubber anti-slip pad 108 and the chrome-plated carbon steel panel 102 are attached to increase the friction. Install the power control components: Fix the transformer control power supply 106 to the front end of the aluminum alloy mounting plate 103 with bolts, and then electrically connect the transformer control power supply 106 to the LED light strip 105 to complete the internal circuit construction. Fixing the main body of the light box to the wall: First, use expansion screws 202 to thread through the galvanized steel back plate 201 and connect it to the wall to fix the galvanized steel back plate 201 to the wall; then align the hook holes 104 of the aluminum alloy frame 101 and the chrome-plated carbon steel panel 102 with the hanging nails 203, and use the hooks to suspend the main frame on the galvanized steel back plate 201. Installing the acrylic lightbox components: The rear end of the acrylic lightbox 301 is fixed with an aluminum alloy outer frame 303, a magnetic inner frame 304, and a Fresnel lens 306, while the front end is fixed with a light-transmitting letter 302. During installation, insert the aluminum alloy frame 101 along the splicing groove 305, and at the same time, make the magnetic inner frame 304 magnetically attract the chrome-plated carbon steel panel 102 to complete the assembly of the entire lightbox.

[0018] The disassembly process is the reverse: First, hold the acrylic light box 301 and pull it outwards to separate the magnetic inner frame 304 from the chrome-plated carbon steel panel 102. Then, pull the aluminum alloy frame 101 out of the splicing groove 305 and remove the acrylic light box 301. Next, separate the hook hole 104 of the main frame from the hanging nail 203 and remove the main frame. If the LED light strip 105 needs to be repaired, the magnet strip 109 can be removed directly from the front end of the chrome-plated carbon steel panel 102 by magnetic separation. When repairing the transformer control power supply 106, simply remove the fixing bolts.

[0019] Efficient assembly and disassembly process: By replacing some bolts with magnetic, hook, and insertion connection methods, assembly does not require tightening bolts one by one, and most parts can be separated without tools during disassembly, greatly shortening assembly and disassembly time; Highly convenient to maintain: Internal components such as LED light strip 105 and transformer control power supply 106 can be quickly removed by magnetic attraction or simple disassembly of bolts, making it easy to inspect and replace; The structure is stable and reliable: the welded main frame ensures the overall strength, the expansion screws 202 ensure that the light box does not shake, and the magnetic and insertion connection restricts the relative displacement of the components, taking into account both convenience and stability.

[0020] To address the problems of traditional light boxes, such as unstable internal components, poor light source stability, uneven light distribution leading to poor display effects, and loose connections, this paper refers to... Figure 2-4 The structure shown; Furthermore, the rubber anti-slip pad 108 is fixedly connected to the LED light strip 105; the magnetic strip 109 is embedded in the rubber anti-slip pad 108 and fixedly connected to the rear end face of the LED light strip 105; the rear end of the galvanized steel back plate 201 is provided with an expansion screw 202, and the expansion screw 202 passes through the galvanized steel back plate 201 and is connected to the wall; the magnetic inner frame 304 is fixedly connected to the acrylic light box 301.

[0021] The magnetic strip 109 is magnetically connected to the chrome-plated carbon steel panel 102. Combined with the friction between the rubber anti-slip pad 108 and the chrome-plated carbon steel panel 102, this effectively limits the displacement of the LED light strip 105 within the lightbox, ensuring stable installation. The expansion screw 202 passes through the galvanized steel back plate 201 and is threaded to the wall, firmly fixing the galvanized steel back plate 201 and the entire lightbox body to the wall, preventing overall shaking or detachment. The magnetic inner frame 304 is fixedly connected to the acrylic lightbox 301, allowing the magnetic inner frame 304 to move synchronously with the acrylic lightbox 301, providing structural support for the magnetic splicing of the acrylic lightbox 301 and the chrome-plated carbon steel panel 102.

[0022] Furthermore, the front end face of the LED light strip 105 is provided with an LED bead 107, and the LED light strip 105 and the LED bead 107 are electrically connected.

[0023] The LED light strip 105 is electrically connected to the LED beads 107, which can stably transmit electrical energy to the LED beads 107, enabling the LED beads 107 to continuously emit light and provide a light source for the interior of the light box. The multiple LED beads 107 are evenly distributed on the front end of the LED light strip 105, which can ensure that the light box emits light evenly and avoid insufficient local brightness from affecting the display effect. At the same time, the LED beads 107 have the characteristics of low energy consumption and long life, which can reduce the long-term use cost of the light box.

[0024] Furthermore, a transformer control power supply 106 is provided at the front end of the aluminum alloy mounting plate 103, and the transformer control power supply 106 is fixedly connected to the aluminum alloy mounting plate 103 by bolts, and the transformer control power supply 106 is electrically connected to the LED light strip 105.

[0025] Specifically, by passing bolts through the screw holes of the transformer control power supply 106 and the aluminum alloy mounting plate 103 and tightening them, the transformer control power supply 106 can be firmly fixed to the front end of the aluminum alloy mounting plate 103, preventing it from falling off due to vibration during the use of the light box. The transformer control power supply 106 is electrically connected to the LED light strip 105 through wires, which can convert the external power supply voltage into the working voltage adapted to the LED light strip 105, ensuring the stable operation of the LED light strip 105 and the LED beads 107, avoiding damage to components due to unstable voltage, and improving the reliability of the device's lighting use.

[0026] Furthermore, an aluminum alloy outer frame 303 is provided on the outside of the magnetic inner frame 304, and the aluminum alloy outer frame 303 is fixedly connected to the rear end face of the acrylic light box 301; a splicing groove 305 is provided between the magnetic inner frame 304 and the aluminum alloy outer frame 303, and the aluminum alloy frame 101 is inserted into the splicing groove 305 for internal connection; the magnetic inner frame 304 is magnetically connected to the chrome-plated carbon steel panel 102.

[0027] The aluminum alloy frame 101 is inserted into the splicing groove 305 along its depth direction. The outer wall of the aluminum alloy frame 101 fits against the inner wall of the splicing groove 305, which can limit the relative displacement of the acrylic light box 301 and the aluminum alloy frame 101 in the horizontal direction. At the same time, the magnetic inner frame 304 and the chrome-plated carbon steel panel 102 are magnetically attracted to each other, which can pull the acrylic light box 301 towards the chrome-plated carbon steel panel 102, further fixing the relative position of the two. This not only ensures the stability of the connection, but also allows the acrylic light box 301 to be quickly disassembled from the main structure by separating the magnetic attraction and pulling out the aluminum alloy frame 101, thus improving the efficiency of disassembly and assembly.

[0028] Furthermore, the aluminum alloy frame 101 is welded to the chrome-plated carbon steel panel 102; the aluminum alloy hanging plate 103 is welded to the chrome-plated carbon steel panel 102.

[0029] The aluminum alloy frame 101 and the chrome-plated carbon steel panel 102 are welded together to form a fusion layer at their contact points, making them an integral structure and enhancing the lightbox frame's resistance to deformation. The welded connection between the aluminum alloy mounting plate 103 and the chrome-plated carbon steel panel 102 ensures that the aluminum alloy mounting plate 103 can stably support the weight of components such as the transformer control power supply 106 and the LED light strip 105, preventing components from falling off due to loose connections and extending the overall service life of the lightbox.

[0030] Furthermore, a Fresnel lens 306 is provided on the inner side of the magnetic inner frame 304, and the Fresnel lens 306 is fixedly installed on the rear end face of the acrylic light box 301; a light-transmitting letter 302 is provided on the front end face of the acrylic light box 301, and the light-transmitting letter 302 is fixedly connected to the acrylic light box 301.

[0031] The light emitted by the LED beads 107 is uniformly diffused after being refracted by the Fresnel lens 306 and fixed to the rear end of the acrylic light box 301 by the Fresnel lens 306, thus avoiding local over-brightness or shadows caused by concentrated light. The light-transmitting lettering 302 is fixedly connected to the acrylic light box 301. The light processed by the Fresnel lens 306 can pass through the light-transmitting lettering 302 evenly, making the lettering clear and bright, significantly improving the advertising display effect of the light box.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
