Description

Technical Field

[0001] This utility model relates to the field of light box technology, specifically to an energy-saving light box that is easy to maintain. Background Technology

[0002] A lightbox is an illuminated installation typically used to display images, text, and visual content. It mainly consists of a frame and transparent lightbox material, with embedded bulbs or LEDs to emit bright light. Lightboxes are widely used in commercial spaces such as shops, hotels, and billboards, attracting attention and enhancing advertising effectiveness at night or in low-light environments.

[0003] Patent CN210378314U discloses a flip-type energy-saving light box that is easy to maintain. It includes a light box body and a lamp tube installed inside the light box body. The light box body includes a housing and a connecting frame. The lamp tube is installed on the inner surface of the housing. The inner walls around the housing body are provided with snap-fit ​​plates. The snap-fit ​​plates are recessed inward to form arc-shaped grooves. This device can disassemble the integrated light box into two parts: the housing and the connecting frame. When there is a problem inside the light box, it can be repaired simply by separating them. It is convenient to operate and easy to maintain.

[0004] However, while this device can open one side of the box by opening the connecting frame, the wear of the arc-shaped clamp at the connection between the box and the connecting frame increases with the number of times the connecting frame is flipped. Over time, this leads to a decrease in the stability between the box and the connecting frame, thus affecting the subsequent flipping of the connecting frame and the maintenance of the light box. Therefore, an energy-saving light box that is easy to maintain is proposed to solve the problem that existing light boxes are difficult to maintain conveniently for internal lighting fixtures.

[0025] Furthermore, the fixed column 3 and the connecting seat 6 have the same diameter, the limiting plate 8 is penetrated by the fixed column 3 and can slide up and down and rotate, and the output shaft of the motor 20 is connected to the connecting seat 6.

[0026] Furthermore, the transparent light box panel 10 is located between the two connecting posts 9, and the limiting groove 12 and the recess 13 have the same shape and size, with the included angle between the limiting groove 12 and the recess 13 being ninety degrees.

[0027] Furthermore, the protective mechanism 7 includes a mounting groove 701 opened on the top of the connecting seat 6, an internal spline 702 is fixedly connected to the inner cavity of the mounting groove 701, and an external spline 703 is provided in the inner cavity of the internal spline 702.

[0028] Furthermore, a support column 704 is fixedly connected to the top of the external spline 703, and a protective canopy 705 is fixedly connected to the top of the support column 704. When the limiting plate 8 is rotated to display content by the motor 20, connecting seat 6 and other structures, the support column 704 can rotate with the connecting seat 6 in conjunction with the internal spline 702 and external spline 703 of the mounting groove 701. The protective canopy 705 can provide rotational shielding and protection for the limiting plate 8, transparent light box panel 10 and other structures, improving the functionality of this energy-saving light box. At the same time, the protective canopy 705 can be removed from the top of the limiting plate 8 in conjunction with the internal spline 702 and external spline 703, further improving the convenience of disassembly and maintenance of this energy-saving light box.

[0029] Furthermore, the display component includes a slot 14 opened on the top of the top limiting plate 8, a placement plate 15 slidably disposed in the inner cavity of the slot 14, the placement plate 15 is made of transparent material, a placement groove 16 is opened on the outside of the placement plate 15, and a second slot 17 is opened through one end of the placement plate 15.
