[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figure 1-6 The present invention includes a cabinet body 1, and an installation plate 2 that fits the back panel is provided inside the cabinet body 1. Each of the four corners of the installation plate 2 has an opening 3. L-shaped positioning rods 4 are fixedly installed on the top and bottom of both sides of the cabinet body 1. The vertical parts of the four positioning rods 4 are fixedly connected to the back panel of the inner wall of the cabinet body 1, and the vertical parts of the four positioning rods 4 are respectively inserted through the four openings 3 on the installation plate 2. Handle assemblies 9 are fixedly installed at the middle height of both sides of the front of the installation plate 2.

[0021] like Figure 4 and Figure 5 As shown, the handle assembly 9 includes a fixing block 91, two connecting plates 92, and a handle 93. The fixing block 91 is fixedly installed on the front of the mounting plate 2. The fixing block 91 is stepped, and grooves 94 are provided on both stepped surfaces of the fixing block 91. Fixing shafts are fixedly installed in the two grooves 94 of the fixing block 91. The top ends of the two connecting plates 92 are respectively located in the two grooves 94 and rotatably sleeved on the corresponding fixing shafts. The two ends of the handle 93 are rotatably connected between the bottom ends of the two connecting plates 92. The two handle assemblies 9 facilitate the movement of the mounting plate 2. When the two handle assemblies 9 are not in use, the two connecting plates 92 will be in a vertical state under the action of gravity, thus avoiding the handle assembly 9 from obstructing the maintenance of electrical components on the mounting plate 2.

[0022] like Figure 4 and Figure 5 As shown, the handle 93 includes two plates, which are located on both sides of the two connecting plates 92. A fixing rod is fixedly installed between the two ends of the two plates. The bottom ends of the two connecting plates 92 are rotatably sleeved on the fixing rods between the two ends of the two plates. Thus, when the handle 93 in the handle assembly 9 is pulled, the two ends of the handle 93 can rotate around the bottom ends of the two connecting plates 92, thereby pulling the two connecting plates 92 so that their top ends are rotated around the fixing axis in the corresponding groove 94. Then, by continuing to pull the handle 93, the mounting plate 2 can be pulled to the opening of the cabinet 1.

[0023] like Figure 1 and Figure 2As shown, slots 5 are provided at both ends of the bottom of the mounting plate 2. Two fixing plates 7 are fixedly installed at the bottom of the cabinet 1. The two fixing plates 7 are located in the two slots 5 at the bottom of the mounting plate 2, and the two fixing plates 7 can support the bottom of the mounting plate 2.

[0024] like Figure 2 and Figure 3 As shown, the bottom of each of the two notches 5 is provided with a semi-circular groove, and a rotatable ball bearing 6 is provided in each of the two semi-circular grooves. The top of each of the two fixed plates 7 is provided with a sliding groove 8. The part of the two balls bearing 6 that extends out of the semi-circular groove is slidably installed in the sliding groove 8 on the top of the two fixed plates 7, which allows the balls bearing 6 to slide in the sliding groove 8 on the fixed plate 7, which can not only support the mounting plate 2, but also make the mounting plate 2 easier to move.

[0025] like Figure 1 and Figure 2 As shown, the side wall of the mounting plate 2 does not contact the side wall of the cabinet 1, which avoids a large friction between the two.
