That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0017] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0018] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0019] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0020] like Figures 1 to 3 As shown, a support device for an electrical box according to the present invention includes two connecting frames 1, a guide rail 2, and screws 3. The two connecting frames 1 are respectively provided on both sides of the electrical box. The guide rail 2 is connected to the connecting frames 1 on both sides of the electrical box by screws 3. The connecting frame 1 is provided with a window 11. The left and right sides of the guide rail 2 are provided with insertion parts 21 that can be inserted into the window 11 and can slide relative to the window. The insertion part 21 is provided with a connecting part 22. One end of the screw is connected to the connecting frame 1, and the other end is screwed to the connecting part 22. Compared with the prior art, this utility model has a window 11 provided in the connecting frame 1, and the left and right sides of the guide rail 2 are provided with insertion parts 21 that can be inserted into the window 11 and slide relative to the window 11. The insertion parts 21 are provided with connecting parts 22. One end of the screw 3 is connected to the connecting frame 1, and the other end is screwed to the connecting part 22. During installation, it is only necessary to first insert the insertion parts 21 on the left and right sides of the guide rail 2 into the window 11 of the connecting frame 1, and then connect one end of the screw 3 to the connecting frame 1 and screw the other end to the connecting parts 22 on the left and right sides of the guide rail 2 to complete the installation. It has the advantages of fewer specific parts, simple structure, convenient installation and high production efficiency.

[0021] Specifically, the window 11 of the connecting frame 1 has inwardly bent first folded edges 12 on both sides, and correspondingly, the insertion parts 21 on the left and right sides of the guide rail 2 have upwardly bent second folded edges 23 that are directly opposite the first folded edges 12. The cross-section of the insertion parts 21 is U-shaped. When the first folded edges 12 and the second folded edges 23 come into contact with each other, they are in surface-to-surface contact, making the insertion parts 21 of the guide rail 2 slide more smoothly and steadily within the window 11.

[0022] Furthermore, the connecting part 22 is a sleeve extending upward from the bottom of the guide rail 2, and the sleeve is provided with an internal thread that is screwed into the screw 3.

[0023] More specifically, the connecting frame 1 includes a first support plate 13, a second support plate 14, and a third support plate 15 arranged laterally, and a longitudinal plate 16 arranged longitudinally to connect the first support plate 13, the second support plate 14, and the third support plate 15 into a whole. The second support plate 14 is provided with a first through hole 141, the third support plate 15 is provided with a second through hole 151, and the screw 3 consists of a head and a threaded part. During installation, simply insert the left and right insertion parts 21 of the guide rail 2 into the windows 11 of the connecting bracket 1, with the second support plate 14 supporting the insertion parts 21. Then, insert the threaded part of the screw 3 into the first through hole 141 of the second support plate 14, with the second support plate 14 supporting the head of the screw 3. Next, insert the threaded part of the screw 3 into the connecting part 22 of the guide rail, engaging with the internal thread of the connecting part 22, and then insert it into the second through hole 151 of the third support plate 15 to complete the installation of the electrical box support device. The threaded part inserted into the first through hole 141 of the second support plate 14 and the second through hole 151 of the third support plate 15 effectively positions the screw 3. When it is necessary to adjust the longitudinal height of the guide rail 2, simply rotate the screw 3. Since the threaded part of the screw 3 is engaged with the connecting part 22 of the guide rail 2, the rotation of the screw 3 will drive the guide rail 2 to move up and down longitudinally, thereby adjusting the longitudinal height of the guide rail 2.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
