It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The present invention provides a pre-embedded box for refrigerator dome lights. Referring to FIGS. The method of removing material can also be formed by a method similar to deep drawing. Obviously, the latter is beneficial to save material. The geometry of the installation cavity 110 can be selected according to the specific structure of the LED lamp board 200. FIG. 1 only shows In one example structure, the LED light board 200 is a rectangular plate structure, and correspondingly, the installation cavity 110 is a rectangular cavity. In this embodiment, the LED lamp board 200 may use a PCB board as a base material for installing the LED lamp bead 210 .

Specifically, the installation cavity 110 is provided with a first buckle 120, a second buckle 130 and a plurality of support parts 140, and the plurality of support parts 140 are arranged at intervals along the circumference of the installation cavity 110, for example, the installation cavity 110 is Taking a rectangular cavity as an example, the support parts 140 are located on the two sides corresponding to the long sides of the installation cavity 110, and two support parts 140 are arranged on each side. Of course, any other suitable number of support parts 140 can also be provided. The position of the support part 140 is changed; the first buckle 120 is arranged opposite to the second buckle 130, and at least one of them is an elastic buckle, so that the LED lamp board 200 is conveniently snapped into the first buckle 120 and the second buckle. Between the buckles 130 , the LED light board 200 stops against the support portion 140 and engages with the first buckle 120 and the second buckle 130 respectively, so as to realize installation and fixation. Also taking the installation cavity 110 as a rectangular cavity as an example, for the implementation structure with two buckles, in order to ensure the fixing effect on the LED lamp panel 200, the first buckle 120 is close to one end of the installation cavity 110 in its length direction, The second buckle 130 is close to the other end of the installation cavity 110 in its length direction.

During specific assembly, one end of the LED light board 200 can be inserted into the engaging position of one of the buckles, and then the other buckle (such as an elastic buckle) is properly pulled outward to increase the receiving capacity of the LED light board 200. After placing the LED light board 200 in place, release the other buckle to complete the assembly. In this embodiment, the LED lamp board 200 is supported by the support part 140, which can ensure that the LED lamp board 200 is placed flat, and can be firmly fixed under the engagement of the two buckles, and the LED lamp board 200 and the installation cavity 110 A certain space is kept between the bottom surfaces to provide avoidance space for the components of the LED light board 200, which is beneficial to protect the LED light board 200 from being damaged during the assembly process. Therefore, by improving the internal structure of the refrigerator dome light pre-embedded box 100, a small number of buckles are used to hold the LED light board 200, and the LED light board 200 is supported by the support part 140, so that the LED light board 200 is firmly fixed and easy to disassemble. Increased production efficiency.

In specific applications, the support portion 140 has various structural forms, for example, the support portion 140 is a boss formed on the bottom surface of the installation cavity 110 , or the support portion 140 is a rib formed on the bottom surface of the installation cavity 110 .
