Description

Technical Field

[0001] The utility model relates to the technical field of light boxes, in particular to a combined multi-layer rotating light box. Background Art

[0002] Lamps are a necessity for modern people's daily life. In addition to their main function of lighting, lamps can also create a special atmosphere in the living environment or match the decoration. Therefore, light boxes are widely used for lighting needs in homes or business places. In order to facilitate the manufacturing and transportation of light boxes, light boxes formed by sheet-type combinations are promoted on the market. The sheet-type light panels and lamp holders are manufactured and transported separately. For example, a sheet-type combination light box structure disclosed in patent authorization announcement No. CN202868395U includes: a light box device, including four light box panels, each of which has an embedding groove on both sides of the upper side of the light box panel; at least one lamp holder, both sides of which are connected to the corresponding light box panel; a lamp set, fixed to the lamp holder, the lamp set at least includes a lamp head seat and a lamp, the lamp is connected to the lamp head seat, the light box panels on the two corresponding sides are reversed and embedded with the light box panels on the two corresponding sides by the corresponding embedding grooves;

[0003] Although the above-mentioned sheet-type combined light box structure can achieve the purpose of being detachable and combined, when in use, due to the existence of the cross groove, after the decorative edge is assembled with the light box board through the cross groove, a protruding edge is formed on the outside of the light box, which brings a bad experience to the flatness of the appearance of the light box, and the protruding edge also brings great inconvenience to the use of the light box case;

[0004] Therefore, the utility model provides a combined multi-layer rotating light box which keeps the exterior of the light box neat. Utility Model Content

[0005] The purpose of the utility model is to provide a combined multi-layer rotating light box to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A combined multi-layer rotating light box, comprising a light box frame, eight aluminum opening and switching screen light strips assembled with the light box frame, and a PC board, wherein the light box frame comprises four aluminum card strips and eight plastic combined corners;

[0008] The plastic combination corner comprises a connector, two plug blocks arranged at right angles on the outside of the connector, and a butt plug arranged below the connector and connected to the connector in a T-shape. The eight plastic combination corners are respectively fixed by plugging and fixing with the sockets at both ends of the four aluminum card strips through the butt plugs.

[0009] The two ends of the PC board are respectively connected with the U-shaped card slots on the inner side of the aluminum opening and switching picture light strip, and the slots at the two ends of the aluminum opening and switching picture light strip are connected with the plug-in blocks to form a cube.

[0010] Furthermore, the aluminum card strip includes an inner support rod and an outer decorative strip, which are respectively isosceles right angles. The socket inside the inner support rod is trapezoidal corresponding to the docking plug. The outer decorative strip is clamped on the outside of the outer decorative strip. After the corresponding trapezoidal docking plug and socket are plugged in, the purpose of stable connection between the connector in the plastic combination corner and the inner support rod in the aluminum card strip is achieved.

[0011] Furthermore, an inner support plate is provided on the inner side of the outer decorative strip, which ensures that the outer decorative strip cooperates with the inner support rod to support the aluminum screen switching light strip and improves the deformation resistance stress of the outer decorative strip when protecting the inner support rod.

[0012] Furthermore, a limit plate for limiting the position of the aluminum screen switching light strip and a clamping plate for clamping and limiting the position of the external decorative strip are provided on the outer side of the lower connecting block of the connecting head. When the external decorative strip is clamped on the outer side of the inner supporting rod, since the external decorative strip is located at a right angle to the corner of the light box frame, the clamping plate at the lower part of the connecting head presses against the inner side of the external decorative strip, so that the external decorative strip is tightened and clamped on the outer side of the light box frame by the clamping plate.

[0013] Furthermore, the top and bottom surfaces of the light box frame are respectively provided with cover plates installed by screws, and the cover plates are used to cooperate with the PC board to protect the top and bottom surfaces of the light box frame to form a box body.

[0014] Furthermore, the outer side surface of the outer decorative strip is on the same plane as the outer side surface of the aluminum opening and switching screen light strip, so as to maintain the neatness of the entire exterior of the light box.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The combined multi-layer rotating light box is formed by assembling an aluminum opening and switching picture light bar and a PC board through an aluminum card strip on a light box frame in cooperation with a plastic combination corner. During assembly, two ends of the PC board are respectively inserted into U-shaped card slots on the bottom surfaces of the corresponding aluminum opening and switching picture light bar, and the slots at both ends of the aluminum opening and switching picture light bar are connected with the plug blocks on the connector in the plastic combination corner to form a cubic light box frame, while fixing the PC board on the light box frame, thereby achieving the purpose of quickly assembling the light box and keeping the outer surface of the light box neat.
