[0027] The utility model provides a low-voltage drawable switch cabinet. When the switch cabinet is opened to install and overhaul internal electronic components, a fixing button on one side of a placement box is stuck in a fixing structure during the opening process, so that the drawer-type placement box can be fixed and cannot be moved, so that the drawer will not move when installing and overhauling internal components, thereby avoiding interference of the placement box with installation and overhaul.

[0028] Figure 1-Figure 5The figure shows the overall structure of a low voltage draw-out switch cabinet of the utility model. Figure 1-Figure 5 In this embodiment, a low-voltage withdrawable switch cabinet has a main body including a main cabinet component and a fixing component.

[0029] The main cabinet assembly includes a switch cabinet body 1, a baffle 2 is provided on the front side of the switch cabinet body 1, a handle 3 is provided on the front side of the baffle 2, a placement box 4 is provided on the rear side of the baffle 2, slide rails 16 are provided on both sides of the placement box 4, fixing bolts 17 are provided on the inner side of the slide rail 16 and fixedly connected to the placement box 4, a fixed rail 18 is provided on the inner wall of the switch cabinet body 1, the slide rail 16 is provided in the fixed rail 18, a control panel 13 is provided on the front side of the baffle 2, a wire outlet hole 14 is provided on the rear side of the placement box 4, and a heat sink 15 is provided on the right side of the switch cabinet body 1.

[0030] The fixing assembly includes a fixing button 5 arranged on the outside of the placement box 4, a mounting plate 6 is arranged on the inside of the switch cabinet body 1, a slide groove is opened on the inside of the mounting plate 6, the fixing button 5 is placed in the slide groove, a hinge 7 is arranged in the mounting plate 6, a fixing ring 8 is arranged on the outside of the hinge 7, a guide plate 9 is arranged on the rear side of the fixing ring 8, a fixing groove 10 is formed between the fixing ring 8 and the mounting plate 6 bracket, a connecting rod 11 is arranged on the outside of the end of the guide plate 9, an empty groove 12 is opened on the outside of the switch cabinet body 1, and the connecting rod 11 passes through the empty groove 12 and extends out of the outside of the switch cabinet body 1. Specifically, in the present embodiment, when the switch cabinet is opened to install and repair the internal electronic components, the placement box 4 is pulled out, and the fixing button 5 on one side of the placement box 4 moves in the slide groove on the mounting plate 6 inside the switch cabinet body 1. When the fixing button 5 touches the guide plate 9, the guide plate 9 continues to move upward under the pressure, so that the fixing ring 8 on one side of the guide plate 9 rotates to an opening angle through the hinge 7 until the fixing button 5 moves to the fixing groove 10 formed between the fixing ring 8 and the mounting plate 6, and the fixing ring 8 falls, so that the fixing button 5 is restricted in the fixing groove 10 and cannot move. At the same time, the placement box 4 is fixed. When it is necessary to retract the placement box 4, the connecting rod 11 extending from the empty groove 12 on one side of the guide plate 9 is pushed upward, and the fixing ring 8 is opened upward to cancel the restriction on the fixing button 5, so that the placement box 4 can be retracted, so that the drawer will not move when installing and repairing the internal components, thereby avoiding the movement of the placement box 4 from interfering with the installation and repair.

[0031] Combination Figure 1-Figure 5 , a low-voltage withdrawable switch cabinet of this embodiment, the specific use process is as follows: when using the switch cabinet body 1, the electronic device is placed in the placement box 4 inside the baffle 2, and the connecting wires of the electronic device are connected through the outlet hole 14 opened on the rear side of the placement box 4. Slide rails 16 are arranged on both sides of the placement box 4, and the slide rails 16 are installed on the inner side of the fixed rail 18. When the handle 3 on the front side of the baffle 2 is pulled, the placement box 4 will be pulled out along the fixed rail 18, and the heat sink 15 on the right side of the switch cabinet body 1 dissipates heat for the internal electronic devices.

[0032] In this embodiment, when the placement box 4 is fixed, the fixing effect of the fixing ring 8 on the fixing button 5 may decrease after long-term use. For this reason, please refer to Figure 1-Figure 5 In this embodiment, a support block 20 is provided inside the mounting plate 6, a spring 21 is provided below the support block 20, a connecting plate 19 is provided above the guide plate 9, the other end of the spring 21 is fixedly connected to the connecting plate 19, and the spring 21 is compressed when the guide plate 9 is lifted. In this embodiment, in order to better limit the placement box 4, when fixing, as the fixing button 5 continuously squeezes the guide plate 9 to open the fixing ring 8 at one end thereof, the connecting plate 19 on the upper side of the guide plate 9 is simultaneously lifted to squeeze the spring 21 connected to the support block 20 on the upper side, so that the spring 21 is compressed. After the fixing button 5 enters the fixing groove 10, the spring 21 rebounds to make the guide plate 9 and the fixing ring 8 at one end thereof fall to limit the fixing button 5, further improving the fixing effect of the fixing ring 8 on the placement box 4.

[0033] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
