Description

Technical Field

[0001] This utility model relates to the field of display light box technology, specifically a display light box locking structure. Background Technology

[0002] A display lightbox is a device that uses a light source to illuminate internal patterns or text. It is usually made of transparent or semi-transparent materials. The main feature of a display lightbox is that it is equipped with an internal light source. Through the transparent or semi-transparent surface of the lightbox, the advertising patterns or text can glow at night or in low-light environments, thereby attracting attention and improving the advertising effect.

[0003] For example, Chinese utility model patent CN219435508U provides a locking structure for a conveniently replaceable advertising lightbox curtain. The lightbox includes a main body with two symmetrically arranged mounting components inside. Each mounting component includes a first threaded rod for adjustment and a T-shaped mounting piece for locking. A mounting plate is locked onto one side of each mounting component, and two hooks are symmetrically installed on the side of the mounting plate near the main body. These hooks overlap with the T-shaped mounting piece. This utility model features a fastening component, allowing for tightening or loosening of the curtain body by rotating a second handle, facilitating curtain replacement. Silicone gaskets are used to press the curtain, preventing displacement and wear. The adjustable mounting components further enhance convenience and speed in fixing the mounting plate, and also facilitate removal of the mounting plate in case of malfunction.

[0004] Currently, most platform display light boxes on the market are opened by rotating the lid upwards. To improve the stability of the connection between the light box body and the lid, a locking structure is installed at the bottom of the box. However, existing locking structures mostly use car side panel locks to fix the box body and the lid. Since car side panel locks are generally large, they are difficult to use for platform display light boxes with a thinner profile. On the other hand, smaller car side panel locks are inconvenient to use and operate, which has significant limitations and affects the effectiveness of the locking structure. Utility Model Content

[0005] The purpose of this utility model is to provide a locking structure for display light boxes to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a display lightbox locking structure, comprising a platform display lightbox body, a locking assembly, and a reinforcing assembly; the platform display lightbox body includes a box body, a box door, and box feet; the box door is rotatably connected to the box body via a hinge and is fixedly connected to the box body via the locking assembly; two box feet are symmetrically fixed to the bottom surface of the box body; the locking assembly includes a fixing block, a fixing plate, a locking groove, and a locking block; a plurality of fixing blocks are linearly arrayed and fixed to the bottom surface of the box body; the fixing plate is fixed to the bottom surface of the box door; a locking groove is provided on the side of the fixing block near the fixing plate; a plurality of locking blocks are linearly arrayed and fixed to the side of the fixing plate near the fixing block and are engaged with the locking groove via the reinforcing assembly.

[0007] Preferably, both the fixing block and the locking block are L-shaped structures, and the dimensions of the fixing block and the locking block on the side closer to the fixing plate are smaller than the dimensions of the fixing block and the locking block on the side farther from the fixing plate.

[0008] Preferably, the locking groove has a semi-arc structure, and the diameter of the locking groove is adapted to the diameter of the locking block.

[0009] Preferably, the reinforcement component includes a rotating plate, a reinforcement groove, and a connecting plate; the rotating plate is rotatably mounted on the fixed blocks via a rotating shaft; the rotating plate has a reinforcement groove; and the connecting plate is fixedly connected to several fixed blocks.

[0010] Preferably, the reinforcing groove includes an abutting part, a receiving part, a reinforcing part, and a limiting part; the abutting part has an arc-shaped structure and contacts the locking block.

[0011] Preferably, the opening size of the receiving portion is larger than the diameter size of the locking block.

[0012] Preferably, the reinforcing part has an arc-shaped structure, the center of the reinforcing part and the center of the locking groove are on the same straight line, and the diameter of the reinforcing part is adapted to the diameter of the locking block.

[0013] Preferably, the limiting part is a planar structure, and the bottom end of the limiting part is lower than the center of the reinforcing part.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, by setting a locking component, allows the door to be rotated via a reinforcing component, causing the door to rotate with the box body via a hinge. This causes the locking block to move within the locking groove until it moves out of the groove, at which point the locking between the door and the box body is released. Then, the advertising screen inside the box can be replaced. After replacement, pressing down on the door causes it to rotate in the opposite direction with the box body via a hinge, allowing the locking block to contact the inner wall of the locking groove via the reinforcing component. Compared to existing technologies, this utility model has a simple and reasonable structure, ingenious design, and achieves locking between the door and the box body through gravity. It is applicable to platform display lightboxes of different thicknesses and sizes, exhibiting strong adaptability and good performance.

[0016] 2. By setting up a reinforcing component, when the door rotates with the body via the hinge, the locking block will press against the limiting part, causing the rotating plate to drive the connecting plate to rotate with the fixed block via the rotating shaft until the locking block contacts the inner wall of the locking groove. At this time, the locking block contacts the receiving part, and under the action of gravity, the rotating plate will drive the connecting plate to rotate in the opposite direction with the fixed block via the rotating shaft until the reinforcing part contacts the locking block. At this time, the connecting plate and the rotating plate rotate back to their original positions. Since the bottom of the limiting part is lower than the center of the reinforcing part, the locking block can be fixed in the reinforcing part, making the door and the body lock more stably.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example: Figures 1-5 As shown, this utility model provides a technical solution for a locking structure of a display lightbox, including a platform display lightbox body 1, a locking assembly 2, and a reinforcing assembly 3; the platform display lightbox body 1 includes a box body 101, a box door 102, and box feet 103; the box door 102 is rotatably connected to the box body 101 via a hinge and is fixedly connected to the box body 101 via the locking assembly 2; two box feet 103 are symmetrically fixedly connected to the bottom surface of the box body 101; the locking assembly 2 includes a fixing block 201, a fixing plate 202, a locking groove 203, and a locking block 204; five fixing blocks 201 are fixedly connected to the bottom surface of the box body 101 in a linear array; the fixing plate 204... 2.

[0030] This utility model, by setting a locking component 2 and a reinforcing component 3 to rotate the box door 102, causes the box door 102 to rotate with the box body 101 via a hinge, causing the locking block 204 to move within the locking groove 203 until the locking block 204 moves out of the locking groove 203. At this point, the locking between the box door 102 and the box body 101 is released. Then, the advertising screen inside the box body 101 can be replaced. After the replacement is completed, the box door 102 is pressed down, causing the box door 102 to rotate in the opposite direction with the box body 101 via a hinge, so that the locking block 204 contacts the inner wall of the locking groove 203 via the reinforcing component 3. Compared with the prior art, this utility model has a simple and reasonable structure and ingenious design. It achieves the locking between the box door 102 and the box body 101 through gravity, and can be applied to the platform display light box body 1 of different thicknesses and sizes. It has strong adaptability and good performance.

[0031] In a preferred embodiment, the reinforcing component 3 includes a rotating plate 301, a reinforcing groove 302, and a connecting plate 303; the rotating plate 301 is rotatably mounted on the fixed block 201 via a rotating shaft; the rotating plate 301 has a reinforcing groove 302; the connecting plate 303 is fixedly connected to five fixed blocks 201; the reinforcing groove 302 includes an abutting part 3021, a receiving part 3022, a reinforcing part 3023, and a limiting part 3024; the abutting part 3021 has an arc-shaped structure and contacts the locking block 204; the receiving part 3022 has an arc-shaped structure and contacts the locking block 204; the receiving part 3023 has an arc-shaped structure and contacts the locking block 204; the receiving part 3022 has an arc-shaped structure and contacts the locking block 204; the receiving part 3022 has an arc-shaped structure and contacts the locking block 204; the receiving part 3022 has an arc-shaped structure and contacts the locking block 204; the receiving part 3022 has an arc-shaped structure and contacts the locking block 204; the receiving part 3022 has an arc-shaped structure and a locking part 302 ...24; the receiving part 3022 has an arc-shaped structure and contacts the locking block 2024; the receiving part 3022 has an arc-shaped structure and contacts The opening size of the receiving part 3022 is larger than the diameter of the locking block 204; the reinforcing part 3023 has an arc-shaped structure, the center of the reinforcing part 3023 is on the same straight line as the center of the locking groove 203, and the diameter of the reinforcing part 3023 is compatible with the diameter of the locking block 204; the limiting part 3024 has a planar structure, and the bottom of the limiting part 3024 is lower than the center of the reinforcing part 3023; when the locking block 204 contacts the receiving part 3022, the door 102 is in a vertical state and contacts the box body 101.

[0032] By setting up a reinforcing component 3, when the door 102 rotates with the body 101 via the hinge, the locking block 204 presses against the limiting part 3024, causing the rotating plate 301 to drive the connecting plate 303 to rotate with the fixed block 201 via the rotating shaft until the locking block 204 contacts the inner wall of the locking groove 203. At this time, the locking block 204 contacts the receiving part 3022, and under the action of gravity, the rotating plate 301 drives the connecting plate 303 to rotate in the opposite direction with the fixed block 201 via the rotating shaft until the reinforcing part 3023 contacts the locking block 204. At this time, the connecting plate 303 and the rotating plate 301 rotate to their original positions. Since the bottom end of the limiting part 3024 is lower than the center of the reinforcing part 3023, the locking block 204 can be fixed inside the reinforcing part 3023, making the door 102 and the body 101 locked more stably.

[0033] Working principle: During use, by moving the connecting plate 303, the rotating plate 301 rotates with the fixed block 201 via the rotating shaft, causing the receiving part 3022 to press against the locking block 204. Simultaneously, rotating the cabinet door 102 causes it to rotate with the cabinet body 101 via the hinge, moving the locking block 204 within the locking groove 203 and the reinforcing groove 302 until it moves out of the locking groove 203. Then, releasing the connecting plate 303 allows gravity to cause both the connecting plate 303 and the rotating plate 301 to rotate back to their original positions, thus releasing the lock between the cabinet door 102 and the cabinet body 101. The advertising screen inside the cabinet body 101 can then be replaced. After replacement, pressing down on the cabinet door 102 causes it to rotate with the fixed block 201 via the hinge. The housing 101 rotates in the opposite direction, causing the locking block 204 to press against the limiting part 3024. This causes the rotating plate 301 to drive the connecting plate 303 to rotate with the fixed block 201 via the rotating shaft until the locking block 204 contacts the inner wall of the locking groove 203. At this time, the locking block 204 contacts the receiving part 3022. Under the action of gravity, the rotating plate 301 will drive the connecting plate 303 to rotate in the opposite direction with the fixed block 201 via the rotating shaft until the reinforcing part 3023 contacts the locking block 204. At this time, the connecting plate 303 and the rotating plate 301 rotate back to their original positions. Since the bottom of the limiting part 3024 is lower than the center of the reinforcing part 3023, the locking block 204 can be fixed inside the reinforcing part 3023, making the locking of the door 102 and the housing 101 more stable.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
