[0002] The lightbox design blends into its surroundings during the day thanks to its unique lighting effect, while at night it immediately stands out due to the illumination, thus attracting people's attention.

[0003] Currently, Chinese patent publication No. CN221769683U, published on September 27, 2024, discloses an illuminated display system comprising several rectangular units. These units consist of profiles forming each edge of the rectangular units and corner connectors forming each corner of the rectangular units, and further include a triple-locking mechanism. One end face of the corner connector has a cylindrical connecting section perpendicular to that end face. The two other end faces of the corner connector, adjacent to the end face with the cylindrical connecting section, each have a square corner slot. The triple-locking mechanism engages in the corresponding square corner slot. A profile recess is formed in the center of the profile, the shape of which corresponds to the outer contours of the triple-locking mechanism and the cylindrical connecting section.

[0004] In this illuminated display system, the cylindrical connecting section and two triple-locking fasteners are used to join the profiles in each of the three orientations of the corner connector. However, the profiles and the cylindrical connecting section must be fastened with screws that pass through limit holes and through-holes. This makes assembling and disassembling the entire display system cumbersome and hinders quick assembly and disassembly. CONTENTS OF THE PRESENT USE SAMPLE

[0005] The present utility model aims to provide a light box with a triple locking mechanism, which enables quick assembly and disassembly of the light box.

[0006] The above objective of the present utility model is achieved by the following technical solution: a light box with a triple snap lock, comprising: horizontal profiles positioned at the top and bottom ends, vertical profiles positioned on the perimeter sides, corner connectors positioned at the corners, triple snap locks attached to the corner connectors, and several light strips, wherein the corner connectors have three triple snap locks, each located at three connection positions, and wherein each corner connector has an embedding groove into which the end section of the triple snap lock can be embedded, and wherein each horizontal and vertical profile has a penetration hole into which the locking head of the triple snap lock can be embedded.and wherein a first operating hole connected to the embedding groove is provided on the side edge of the corner connector, from which an eccentric wheel of the triple locking mechanism can be led out.

[0007] The present utility model is further designed such that the vertical profile comprises a first profile on the top and a second profile on the bottom, wherein a triple locking mechanism is also arranged between the first profile and the second profile, the two ends of which are each embedded in the penetration hole on the top and bottom, wherein a second operating hole connected to the penetration hole is provided at the upper end of the second profile, from which the eccentric wheel of the triple locking mechanism can be led out.

[0008] The present utility model is further designed in such a way that a first installation groove for installing the light strips is provided on the inside of the horizontal profile and the vertical profile.

[0009] The present utility model is further designed such that the horizontal and vertical profiles enclose a stone column with a rectangular cross-section, wherein a second installation groove is provided on the inside of the horizontal profile, which is inclined relative to the horizontal profile in order to attach the light strips, and wherein a horizontal fitting section is further provided on the inside of the horizontal profile, which abuts the outer wall of the stone column, and wherein two third installation grooves are provided on the inside of the vertical profile, which are inclined relative to the vertical profile in order to attach the light strips, and wherein a vertical fitting section is further provided on the inside of the vertical profile, which abuts the outer wall of the stone column, and wherein a first rectangular surface is provided on a side of the vertical fitting section facing away from the vertical profile.

[0010] The present utility model is further designed such that a corner fitting head is arranged on the corner connector, wherein a threaded hole is provided in the corner connector, and wherein a through hole corresponding to the threaded hole is provided on the corner fitting head, and wherein a connecting bolt is arranged on the corner fitting head, which is passed through the through hole and screwed inside the threaded hole, and wherein a first clamping hole is provided in the horizontal fitting section, and wherein a first clamping head is arranged on the corner fitting head which is embedded in the first clamping hole, and wherein a second clamping hole is provided in the vertical fitting section, and wherein a second clamping head is arranged on the corner fitting head which is embedded in the second clamping hole, and wherein a second rectangular surface is provided on the corner fitting head.

[0011] In summary, the present utility model has the following advantages: 1. During assembly of the light box, the end sections of the triple locking mechanism are inserted into the recess of the corner connector. The three triple locking mechanisms on the corner connector then correspond to two horizontal profiles and one vertical profile. Next, the locking heads of the triple locking mechanisms are inserted into the penetration holes of the horizontal and vertical profiles. Then, the eccentric wheel of the triple locking mechanism is turned through the first operating hole. The corner connector can then be quickly connected to the two horizontal profiles and the one vertical profile using the three triple locking mechanisms. When disassembling the light box, only the eccentric wheel in the first operating hole needs to be loosened to unlock the triple locking mechanism, allowing the horizontal and vertical profiles to be removed.This ultimately facilitates the quick assembly and disassembly of the light box using the triple locking mechanism. 2. By using vertical profiles consisting of a first profile and a second profile, the vertical profiles can be connected to each other. Simultaneously, the use of a triple locking mechanism and a second access hole allows for quick assembly and disassembly between the first and second profiles, further facilitating the rapid assembly and disassembly of the light box using the triple locking mechanism. 3. By using the first installation groove located on the inside of the horizontal and vertical profiles to install the light strips, the lighting inside the light box is facilitated. 4. If the light box needs to enclose a stone column, lateral illumination is required. A second installation groove, angled relative to the horizontal profile, is now provided on the inside of the horizontal profile to accommodate the light strips. Two third installation grooves, also angled relative to the vertical profile, are provided on the inside of the vertical profile to accommodate the light strips. This configuration allows for lateral illumination of the light box on the stone column. When installing the vertical and horizontal profiles on the stone column, the horizontal profile rests on the outer wall of the column over the horizontal fitting section, while the vertical profile fits onto the edge of the column over the first right-angled surface of the vertical fitting section. This ultimately ensures stable support for both the horizontal and vertical profiles on the stone column. 5. Simultaneously, a corner fitting head arranged on the corner connector is used. The corner fitting head fits the edge of the stone column by means of the second right-angled surface, thus enabling stable support of the corner connector on the stone column. The corner fitting head uses a first clamping head that is embedded in the first clamping hole of the horizontal fitting section, and a second clamping head that is embedded in the second clamping hole of the vertical fitting section, thus enabling stable installation of the corner fitting head between the vertical and the horizontal profiles.
