Description

Technical Field

[0001] This utility model relates to a fabric light box, belonging to the field of display lighting equipment. Background Technology

[0002] A lightbox is a special type of lightbox advertising display device, typically used in indoor or outdoor commercial display areas such as shopping malls, cinemas, and hotel lobbies. It generally adopts an ultra-thin design and a frame structure, using LED light strips or spotlights fixed within the frame structure as the light source. A soft film is applied to the outer layer of the frame. Compared with traditional lightboxes, it consumes less power, effectively reducing energy consumption and maintenance costs.

[0003] Existing light boxes typically feature a one-piece structure or a two-part frame structure, generally using a bottom LED strip as the light source. These light boxes suffer from several problems: firstly, their structure is relatively bulky, making them difficult to move during use; secondly, due to the use of LED strips or single LED point light sources, the lighting effect is poor, and the lighting on the flexible film displaying the content is extremely uneven, resulting in a subpar display effect.

[0004] To solve the above technical problems, it is necessary to develop a portable lightbox with better lighting effects. Utility Model Content

[0005] The purpose of this invention is to provide a lightbox to solve the above-mentioned technical problems.

[0006] The technical solution to achieve the purpose of this utility model is:

[0007] A lightbox includes a bracket, an LED light-emitting panel, a power supply, and an advertising board. The bracket includes mutually perpendicular rectangular frames, the LED light-emitting panel is fixed on the rectangular frame, and the advertising board covers the surface of the rectangular frame. The rectangular frame is formed by splicing profiles and integrated detachable fixing buckles, and the detachable fixing buckles are connected to the profiles by spring-loaded limit keys.

[0008] The light box of this application uses a profile frame and an integrated detachable fixing buckle for connection. Compared with the existing profile and movable buckle combination on the market, it has better stability during disassembly and is lighter in overall weight, making it more adaptable to occasions with high requirements for mobility and service life.

[0009] Further or optionally, the profile has a cross-section that is a rectangle with arc-shaped extensions on both sides, the arc-shaped extensions being higher than the rectangle's edge, and the profile also has reinforcing ribs parallel to the plane of the rectangular frame.

[0010] The profile of this application has an irregular cross-section and is equipped with reinforcing ribs, which reduces the possibility of wobbling during the engagement with the detachable buckle and improves its structural stability. The reinforcing ribs can enhance the overall strength of the frame and extend its service life.

[0011] Further or optionally, to expand the display area, the rectangular frame has an interconnected upper frame and a lower frame, with a transverse support rod between the upper and lower frames; the upper and lower frames are connected by detachable fixing buckles, and a fixing key is provided at the connection between the upper and lower frames to fit against the inner profile surface of the rectangular frame; the fixing key has a positioning screw hole on the side close to the rectangular frame, and a first support rod limiting groove is provided on the side of the fixing key that contacts the transverse support rod; the transverse support rod has positioning posts at both ends, and each positioning post has a positioning groove, which cooperates with the first support rod limiting groove, and the first support rod limiting groove has an arc-shaped support that fits against the positioning groove.

[0012] In certain situations, in order to meet the needs of larger-format display, the rectangular frame is divided into at least two groups connected in parallel. The junction of the two groups of rectangular frames is connected by a three-way movable buckle. A transverse connecting buckle is provided on the longitudinal profile between the two adjacent groups of rectangular frames. The surface of the transverse connecting buckle that is in contact with the longitudinal profile has a positioning screw hole. A second support rod limiting groove is also provided at the contact position between the transverse connecting buckle and the transverse support rod.

[0013] Further or alternatively, in order to enhance the flexibility of the detachable fixing buckle and make it fit the aluminum alloy section better, the detachable fixing buckle is an integral structure, with one end inserted into the profile fitting the shape of the inner surface of the profile. The detachable buckle has at least two ports, with at least one end having a spring-loaded limit key. The spring-loaded limit key and the detachable fixing buckle are connected by an integral plate spring.

[0014] Further or alternatively, in order to make the light box more stable during use, an LED light-emitting panel fixing foot is also provided. One end of the light-emitting panel fixing foot is rotatably fixed to one side of the rectangular frame, and the other end is in contact with the LED light-emitting panel. The LED light-emitting panel fixing foot is elastic, and a flat pressure foot is provided at the contact position with the LED light-emitting panel. The flat pressure foot is in contact with the LED light-emitting panel.

[0015] When the fabric light box needs to be placed on the ground, a base can be set on one side of it, and the entire fabric light box can be placed on the base, with the base in contact with the ground. This can prevent the fabric light box from contacting the ground and causing pollution to the display area, and can also effectively prevent the fabric light box from tipping over by increasing the weight of the base and the contact area between the base and the ground.

[0016] Further or alternatively, in order to reduce the power supply limitations of the light box, the power supply of the LED light panel can be switched between AC power mode and battery mode.

[0017] Further or alternatively, in order to facilitate the replacement of the display content and enhance the stability of the display board, the advertising board is a two-sided design with a zipper between the two sides, and the zipper closing surface is arranged along the side of the rectangular frame.

[0018] Further or alternatively, in order to reduce the weight of the light box, the bracket is made of ultra-light aluminum profile.

[0019] Further or optionally, in order to effectively improve the strength of the aluminum profile, the profile section of the rectangular frame has a horizontal central portion set close to the center of the frame and sidewalls parallel to the rectangular frame surface. The horizontal central portion has a first semi-circular shape and a second semi-circular shape on both sides that are higher than the horizontal central portion. The first semi-circular shape and the second semi-circular shape have a vertical transition surface with the horizontal central portion. The sidewalls are provided with reinforcing ribs that are parallel to the first semi-circular shape and the second semi-circular shape.

[0020] To improve the connection stability between the aluminum profile and the detachable buckle, the reinforcing ribs are arranged in three layers. The first left reinforcing rib and the second left reinforcing rib, which are close to the first semi-circle, are arranged parallel to the outside of the first semi-circle. The first right reinforcing rib, which is close to the outside of the second semi-circle, is arranged parallel to the outside of the second semi-circle. The second right reinforcing rib is arranged inside the second semi-circle and has a gap between it and the second semi-circle.

[0021] By adopting the above technical solution, this utility model has the following beneficial effects:

[0022] (1) The light box of this utility model is connected by a profile frame and an integrated detachable fixing buckle. Compared with the existing profile plus movable buckle combination on the market, it has better stability during disassembly and is lighter overall. It is more adaptable to occasions with high requirements for mobility and service life.

[0023] (2) The profile of the light box of this utility model has an irregular cross section and is equipped with reinforcing ribs, which reduces the possibility of shaking during the process of engaging with the detachable buckle and makes its structure more stable; the setting of reinforcing ribs can improve the overall strength of the frame and extend the service life of the frame.

[0024] (3) In order to expand the structural extensibility, this utility model is designed with a fixing key and a transverse connecting buckle structure. The connection structure has good stability and is more flexible in situations where expansion is required.

[0025] (4) The buckle structure of this utility model adopts an integrated plate spring design for the spring-loaded positioning key, which does not have any parts that are easy to fall off, resulting in a longer service life, a shorter parts processing flow, and a greater cost advantage.
