Description

Technical Field

[0001] This utility model relates to the field of light box technology, specifically to a light box that is easy to assemble and disassemble. Background Technology

[0002] A lightbox is a display device used in exhibitions. Generally, the outside of a lightbox is covered with an advertising display cloth, and a light source is installed inside.

[0003] Currently, light boxes are widely used in shopping malls, subways, and exhibition venues. Existing light boxes are assembled from profiles. Traditional light box assembly structures are fixed, mostly using screws or welding. During installation, tools are needed to assemble each piece, and during disassembly, screws need to be repeatedly tightened and loosened, which is time-consuming and laborious. Especially when it is necessary to frequently change the image or repair internal components, the operation efficiency is low. Utility Model Content

[0004] The main purpose of this utility model is to provide a light box that is easy to assemble and disassemble, in order to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a light box that is easy to assemble and disassemble, including a mounting frame, a support plate on the mounting frame, a light box mounted on the support plate, connecting shafts at both ends of the support plate, and limiting structures at both ends of the connecting shafts.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the limiting structure includes a support, a hinge is provided on the top side of the support, an arc-shaped limiting block is installed on the hinge, and a limiting groove is provided at the limiting end of the arc-shaped limiting block; the support is provided with an installation cavity, a sliding groove is provided at the top of the installation cavity, a slider is provided in the sliding groove, and a locking block is provided at one end of the slider.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: a mounting groove is provided on one side of the mounting cavity, and a spring is provided in the mounting groove; a connecting arm is provided at the bottom of the slider, and one side of the connecting arm is fixedly connected to the spring.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: a top rod is provided on the other side of the connecting arm, and a pressure block is provided at one end of the top rod.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: both the limiting slot and the card block are trapezoidal structures.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: a fixing groove is provided on one side of the slide, and the size of the fixing groove is adapted to the limiting end size of the arc-shaped limiting block.

[0011] The beneficial effects of this utility model are as follows: By setting a limiting structure, the arc-shaped limiting block is rotated by a hinge, so that the limiting groove on the arc-shaped limiting block is engaged with the locking block at one end of the slider, thereby forming a mechanical lock. By pressing the top rod with the pressure block, the locking block and the limiting groove can be released. This makes it easy to disassemble and assemble the entire light box without the need for tools, thus improving the efficiency of disassembly and assembly. Attached Figure Description

[0013] Figure 2 This is a schematic diagram of the limiting structure of this utility model. Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0015] See attached diagram. Figures 1 to 2 The light box in this embodiment is easy to assemble and disassemble, including a mounting frame 1, a support plate 10 on the mounting frame 1, a light box 2 mounted on the support plate 10, and connecting shafts 11 at both ends of the support plate 10, with limiting structures at both ends of the connecting shafts 11.

[0016] Furthermore, the limiting structure includes a support 3, a hinge 4 on one side of the top of the support 3, an arc-shaped limiting block 5 installed on the hinge 4, and a limiting groove 50 at the limiting end of the arc-shaped limiting block 5; the support 3 has an installation cavity 30, a sliding groove 31 at the top of the installation cavity 30, a slider 6 in the sliding groove 31, and a locking block 60 at one end of the slider 6.

[0017] Furthermore, a mounting groove 32 is provided on one side of the mounting cavity 30, and a spring member 7 is provided in the mounting groove 32; a connecting arm 31 is provided at the bottom of the slider 6, and one side of the connecting arm 31 is fixedly connected to the spring member 7.

[0018] Furthermore, a push rod 8 is provided on the other side of the connecting arm 31, and a pressure block 80 is provided at one end of the push rod 8.

[0019] Preferably, both the limiting slot 50 and the card block 60 are trapezoidal structures.

[0020] Preferably, a fixing groove 33 is provided on one side of the slide groove 31, and the size of the fixing groove 33 is adapted to the size of the limiting end of the arc-shaped limiting block 5.

[0021] The working principle of this embodiment is as follows: When the light box 1 is in an unassembled state, the spring 7 is in an extended state, and the locking block 60 at the head of the slider 6 is located above the fixing groove 33. During assembly, the hinge 4 in the limiting structure rotates to drive the arc-shaped limiting block 5 to move. The limiting end of the arc-shaped limiting block 5 first contacts the head of the locking block 60. As the limiting end of the arc-shaped limiting block 5 moves down continuously, the locking block 60 is squeezed, causing the slider 6 to slide to the right in the slide groove 31, and at the same time, it causes the connecting arm 31 to move to the right to squeeze the spring. When the spring 7 is compressed, and the limiting groove 50 of the arc-shaped limiting block 5 engages with the locking block 60, and the limiting end of the arc-shaped limiting block 5 engages with the fixing groove 33, the spring 7 returns to its original state, thus forming a mechanical lock. At this time, the connecting shaft 11 can be fixed and limited. By pressing the top rod 8 with the pressure block 80, the locking block 60 and the limiting groove 50 can be unlocked, thereby releasing the lock of the connecting shaft 11. This facilitates the overall disassembly and assembly of the light box 1 without the need for tools, improving the efficiency of disassembly and assembly.

[0022] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
