Description

Technical Field

[0001] The utility model belongs to the technical field of light boxes, in particular to an embedded invisible light box with changing pictures. Background Art

[0002] Advertising light boxes are commonly used in streets, subway stations, shopping malls and other places. They usually adopt embedded installation method, that is, a position for installing the advertising light box is reserved on the mounting plate or mounting frame where the advertising light box is installed. To facilitate the installation of the advertising light box, the reserved position will be larger than the external dimensions of the advertising light box. After the advertising light box is installed, a gap will be left between the four sides of the advertising light box and the reserved position.

[0003] The current embedded invisible light box with picture-changing function has no gap between the light box and the wall after being embedded, which makes it difficult to repair or replace parts of the light box.

[0004] For example, a prior art Chinese patent document (Application Publication No. CN206711541U) describes a recessed light box. The device allows the base plate, adjustment bracket, and embedded plate to be hoisted separately to the mounting area before adjustment, or it can be adjusted first and then hoisted and installed as a whole. Adjusting the light intensity and the position of the hollow hole using the adjustment bracket is simple and easy to operate. The lamp and hollow hole are accurately aligned, and the lamp housing is not easily damaged. However, this prior art has the following problem: after being embedded, there is no gap between the light box and the wall, making repair and part replacement difficult.

[0005] Therefore, in view of this situation, it is urgent to design and produce a kind of embedded picture-changing invisible light box to meet the needs of actual use. Utility Model Content

[0006] The purpose of the utility model is to provide an embedded invisible light box with changing pictures to solve the problems raised in the background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an embedded picture-changing invisible light box, comprising a mounting plate and an embedded picture-changing invisible light box body, a first motor for assisting the embedding of the invisible light box body being installed on the upper side of the mounting plate, an output end of the first motor being fixedly connected to a bidirectional threaded rod, a side edge of the bidirectional threaded rod being sleeved with a first limit block fixedly connected to the mounting plate, a side edge of the bidirectional threaded rod being screwed with a first sliding block slidably connected to the mounting plate, an upper side of the first sliding block being rotatably connected to a second connecting rod, a side edge of the second connecting rod being rotatably connected to a third connecting rod, an upper side of the third connecting rod being fixedly connected to a third sliding block slidably connected to the invisible light box body.

[0008] Preferably, a first connecting rod is fixedly connected to a side of the first sliding block, and a second sliding block slidably connected to the mounting plate is fixedly connected to a lower side of the first connecting rod.

[0009] Preferably, a telescopic sleeve fixedly connected to the mounting plate is fixedly connected to the lower side of the invisible light box body, and a protective cover for facilitating the replacement of the invisible light box body is clamped to the upper side of the invisible light box body.

[0010] Preferably, the side of the protective cover is threaded with fixing bolts for fixing the invisible light box body and the protective cover, and a hydraulic rod is installed on the lower side of the invisible light box body.

[0011] Preferably, the extended end of the hydraulic rod is fixedly connected to a support plate, and a fan is installed on the side of the invisible light box body.

[0012] Preferably, a detachable filter plate is installed on the side of the invisible light box body.

[0013] Preferably, the support plate is snap-connected to the invisible light box body.

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

[0015] The embedded picture-changing invisible light box starts a first motor to drive a bidirectional threaded rod to rotate, and the rotation of the bidirectional threaded rod drives the first sliding block to move. The movement of the first sliding block drives the angle of the second connecting rod to change, and drives the invisible light box body to move outward, so that the invisible light box body is away from the wall, which is convenient for repair and replacement of the invisible light box body. At the same time, the hydraulic rod is started to drive the support plate to move, and the support plate contacts the ground to support the invisible light box body.

[0016] The embedded picture-changing invisible light box blows external air into the invisible light box body through a fan, and exhausts hot air to the outside through a filter plate, thereby preventing the use of the invisible light box body from being affected by excessive temperature.
