Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a double-layer shell vacuum-formed light box. Background Technology

[0002] Advertising light boxes are generally made of materials such as vacuum forming, acrylic, and inkjet cloth, and are advertising carriers with a box-type hollow structure. They are waterproof and luminous, and are mainly suitable for indoor and outdoor advertising.

[0025] The terms "first" and "second" in this utility model do not represent specific quantities or orders, but are merely used to distinguish names.

[0026] Combined with appendix Figure 1 and 2 This embodiment of a double-layer shell vacuum-formed light box includes a back shell 1, a connecting bracket 2, an inner cover 3, and a front cover 4. The back shell 1 is a cylindrical structure with an internal cavity, and its side near the inner cover 3 and the front cover 4 is open. An LED light-emitting module is installed inside the back shell 1 and emits light towards the inner cover 3 and the front cover 4. The connecting bracket 2 is connected to the back shell 1 and serves as an intermediate connector connecting the back shell 1 and the cover. The inner cover 3 and the front cover 4 are both connected to the connecting bracket 2. The front cover 4 covers the inner cover 3. The inner cover 3 is made of milky white acrylic material and plays a role in uniform light distribution, making the light uniform after illumination. The front cover 4 is made of transparent acrylic material and has a vacuum electroplated surface, exhibiting a mirror effect. The inner cover 3 and the front cover 4 are double-layer acrylic vacuum-formed.

[0027] This double-layer shell vacuum-formed light box uses the inner cover 3 to ensure uniform lighting after illumination. When the power is off, the mirror effect of the outer cover 4 allows the light box to be used as a mirror. Moreover, the double-layer shell design improves the sealing of the light box, effectively extending the lifespan of the internal LED light-emitting modules.

[0028] As a preferred embodiment of this utility model, the connecting bracket 2 includes a connecting frame 21, which abuts against the back shell 1 and connects the inner cover 3 and the front cover 4. The diameter of the connecting frame 21 is close to the diameter of the back shell 1, and the connecting frame 21 seals against the open side edge of the back shell 1. The connecting member 22 is used to fix the connecting frame 21 and the back shell 1 to maintain the sealing effect between the connecting frame 21 and the back shell 1.

[0029] As a preferred embodiment of this utility model, the connector 22 includes a first connecting part 221, which connects to the back shell 1; and a second connecting part 222, which connects to the connecting frame 21. Multiple second connecting parts 222 are evenly spaced along the circumference of the connecting frame 21. The first connecting part 221 and the second connecting part 222 are integrally formed. The first connecting part 221 and the back shell 1 are connected by screws 5. The first connecting part 221 is located on the inner circumference of the back shell 1. The screws 5 pass through the back shell 1 from the outside and connect to the first connecting part 221. The second connecting part 222 includes a straight part 2221 and a bent part 2222. The connecting frame 21 has a slot that mates with the straight part 2221. The straight part 2221 passes through the slot 211 on the connecting frame 21 along its axial direction. The bent part 2222 is formed by bending the end of the second connecting part 222 and abuts against the side of the connecting frame 21 facing away from the back shell 1.

[0030] As a preferred embodiment of this utility model, the inner cover 3 has an inner cover circular edge 31 on its edge. The inner peripheral wall of the inner cover circular edge 31 abuts against the straight part 2221. The outer side wall of the straight part 2221 is an arc shape that matches the inner peripheral wall of the inner cover circular edge 31. Multiple straight parts 2221 cooperate with the inner cover circular edge 31 to achieve the positioning of the inner cover 3.

[0031] As a preferred embodiment of this utility model, the edge of the cover 4 is provided with a cover round edge 41, and the edge of the connecting bracket 2 is provided with a bracket round edge 23 that cooperates with the cover round edge 41. The inner diameter of the bracket round edge 23 matches the outer diameter of the cover round edge 41, and the bracket round edge 23 and the cover round edge 41 cooperate to achieve the positioning of the cover 4.

[0032] As a preferred embodiment of this utility model, the inner cover 3 and the outer cover 4 are fixed to the connecting frame 21 by sealant.

[0033] As a preferred embodiment of this utility model, it also includes a wall connector 6 disposed on the back of the back housing 1. The back of the back housing 1 is provided with a groove 7 for accommodating the wall connector 6. The groove 7 is formed by the inward indentation of the back of the back housing 1. The groove 7 is not connected to the inner cavity of the back housing 1. The groove 7 is provided so that the back of the back housing 1 can still be tightly fitted to the wall when the wall connector 6 is installed, thereby realizing the concealed installation of the wall connector 6.

[0034] As a preferred embodiment of this utility model, the wall connector 6 includes two interlocking hanging corners, which are L-shaped structures with an included angle of less than 90°. One corner is fixed to the wall and the other is fixed in the groove 7. When in use, the two corners can be interlocked to connect the wall and the back shell 1, and the assembly and disassembly are relatively convenient.

[0035] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
