[0021] The following will disclose multiple embodiments of the present invention with drawings. For the purpose of clear description, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present invention. In other words, in some embodiments of the present invention, these practical details are not necessary. In addition, in order to simplify the drawings, some conventional structures and components will be depicted in a simple schematic manner in the drawings.

[0022] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0023] In addition, in the present utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present utility model. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0024] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0025] like Figures 1 to 4 As shown, an electric box of the utility model comprises: a box body 1, a plastic support 2, a support rail 3 and a stud 4. A support 11 is provided on each side of the box body 1, and a mounting hole 12 is provided on each side of the support 11; elastic hooks 21 that can be buckled in the mounting hole 12 of the support 11 are provided on each side of the plastic support 2, and both ends of the support rail 3 are respectively connected to the plastic support on the support 11; and studs 4, the upper end of the stud 4 is connected to the plastic support 2, and the lower end of the stud 4 is connected to the support rail 3. Compared with the prior art, the utility model is provided with a mounting hole 12 on each side of the support 11, and correspondingly, elastic hooks 21 that can be buckled in the mounting hole 12 of the support 11 are provided on each side of the plastic support 2. When installing or removing, the plastic support 2 can be installed on the mounting hole 12 of the support 11 or removed from the mounting hole 12 by hand, and the plastic support 2 can be injection molded at one time, which has the advantages of convenient installation and removal and high production efficiency.

[0026] Furthermore, the support member 11 is provided with a recessed chamber 13 for accommodating the plastic support 2. The recessed chamber 13 can not only be used to accommodate the plastic support 2, but also can limit the plastic support 2 from moving backwards, and can cooperate with the elastic hook 21 to be buckled in the mounting hole 12 of the support member 11, so that the support member 11 can limit the plastic support 2 from moving forwards and backwards, up and down, and left and right.

[0027] In addition, the plastic support 2 is provided with a groove 22, and a metal reinforcement 23 is embedded in the groove 22. The metal reinforcement 23 is L-shaped. One end of the metal reinforcement 23 is embedded in the groove 22, and the other end is against the outside of the groove 22. The L-shaped metal reinforcement 23 is convenient for the metal reinforcement 23 to be positioned by the other end of the metal reinforcement 23 when it is inserted into the groove 22. When the other end of the metal reinforcement 23 is against the outside of the groove 22, it means that the metal reinforcement 23 is inserted into place. Two positioning holes 231 are provided at one end of the metal reinforcement 23, and two positioning blocks 221 that can be buckled on the positioning holes 231 are provided on the lower side of the groove 22. When the metal reinforcement 23 is inserted into the groove 22 and is in place, the positioning blocks 221 on the lower side of the groove 22 are just buckled on the positioning holes 231, and the metal reinforcement 23 will not fall off from the groove 22. The installation of the metal reinforcement 23 is simple and convenient, and it can also enhance the strength of the plastic support 2.

[0028] Furthermore, the support rail 3 is provided with a threaded hole 31, and the lower end of the stud 4 is screwed with the threaded hole 31 of the support rail 3. The plastic support 2 is also provided with a positioning clip 24 that can position the stud 4, and the positioning clip 24 is U-shaped. The plastic support 2 is provided with a first recess 25 that can accommodate the stud 4, and the metal reinforcement 23 is also provided with a second recess 232. When installing the stud 4, it is only necessary to press the stud 4 into the first recess 25, the second recess 232 and the positioning clip 24. The opening size of the first recess 25 is larger than the opening size of the second recess 232. The head of the stud 4 abuts against the metal reinforcement 23. The opening size of the second recess 232 is smaller than the diameter of the head of the stud 4 and larger than the diameter of the column of the stud 4, so that the stud 4 can be suspended on the second recess 232 and will not move downward. The positioning clip 24 clamps the middle part of the stud 4 to limit the left and right and front and back movement of the stud 4. Rotating the stud 4 can drive the support rail 3 to rise and fall.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
