[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-3As shown in the figure, there is a drawer 1 of a low-voltage switchgear cabinet. An external wiring port 9 is provided on the rear side wall of the drawer 1, and a locking member 11 is provided at the front end of the bottom of the drawer 1. It also includes a shelf plate 6. The shelf plate 6 is in a "Ji" shape. The shelf plate 6 is arranged on the upper surface of the bottom of the drawer 1 and is detachably connected to the bottom of the drawer 1. The height of the shelf plate 6 is lower than the height of the side wall of the drawer 1. A through hole 4 is opened at the position of the bottom plate of the drawer 1 corresponding to the shelf plate 6. A plurality of mounting holes 5 are opened on the bottom, side wall, top and side wall of the drawer 1 and the shelf plate 6; a plurality of through holes 3 are opened at the protruding position of the bottom of the shelf plate 6. Threaded holes are opened on the upper surface of the bottom of the drawer 1 corresponding to the positions of the through holes 3. The shelf plate 6 is fixed to the drawer 1 by screwing a screw 7 through the through hole 3 and into the threaded hole; a reinforcing rib 10 is horizontally arranged on the bottom surface of the drawer 1; the shelf plate 6 can be inserted upside down into the through hole 4; the edges of the upper surface and the side wall of the shelf plate 6 are designed with rounded corners 8.

[0021] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, which are as follows:

[0022] It should be understood that the sizes and heights of the components 2 in the drawer 1 of the low-voltage switchgear cabinet are different. To meet the installation of some relatively tall components 2, the height of the drawer 1 needs to be higher than the height of the components 2. However, most of the heights of the components 2 are much lower than the height of the drawer 1. The installation of the components 2 needs to rely on the mounting holes 5 at the bottom of the drawer 1. Therefore, the space utilization rate in the middle and upper parts of the drawer 1 is very low. Based on this feature, the present invention has made structural improvements, and the specific implementation methods are as follows:

[0023] According to the attached drawings of the specification Figure 1-3 It can be seen that the shelf plate 6 in the present invention is installed on the upper surface of the bottom of the drawer 1. The specific installation position is not limited, but it needs to be reasonably allocated according to the installation positions of other components 2 in the drawer 1. As Figure 1 shown, if the shelf plate 6 is installed at the position of the central line, then the relatively tall components 2 in the drawer 1 can be installed on both sides of the bottom of the drawer 1, and the relatively low components 2 can be installed on the top of the shelf plate 6. This allocation method can be understood and reasonably applied by those skilled in the art. In the present invention, since the shelf plate 6 is in a "Ji" shape, components 2 can be installed not only on the top of the shelf plate 6 but also on the side walls of the shelf plate 6. Of course, it is inevitable to open mounting holes 5 on the top and side walls of the shelf plate 6. According to the need for the components 2 to be installed by means of the mounting holes 5 and compared with the original drawer 1, there is an additional installation area on the two side walls of the shelf plate 6, or an additional installation position on the two side walls of the shelf plate 6. Without changing the volume of the cabinet body and without affecting the normal use of the drawer 1, more components 2 can be installed, improving the space utilization rate inside the drawer 1 and inside the cabinet body.

[0024] Among them, a plurality of through holes 3 are opened at the protruding position of the bottom of the shelf 6, and threaded holes are opened on the upper surface of the bottom of the drawer 1 corresponding to the positions of the through holes 3. The shelf 6 and the drawer 1 are fixed by screws 7 passing through the through holes 3 and screwing them together with the threaded holes. Fixing by means of screws 7 is relatively simple and convenient. Of course, it is not limited to the detachable fixation by means of screws 7, and it can also be installed by the existing detachable clamping method.

[0025] Among them, the bottom surface of the drawer 1 is horizontally provided with reinforcing ribs 10 to increase the strength of the bottom of the drawer 1. The shelf 6 can be inserted into the through opening 4 upside down. This method is used in conjunction with the lower drawer 1. If some equipment is too high, even higher than the height of the drawer 1, this method can be easily solved, such as Figure 3 As shown, the applicability is greatly improved.

[0026] In addition, the edges of the upper surface of the shelf plate 6 and the side wall are designed with rounded corners 8 to prevent people from being scratched when installing or removing the component 2.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
