[0026] like Figure 1-Figure 7 As shown, the installation and fixing structure of an electrical cabinet in the utility model is similar to the installation and fixing structure of an existing electrical cabinet, such as the installation structure of a building electrical cabinet disclosed in the patent with publication number CN217522413U. The main improvement of the utility model is that the user can install the cabinet body 1 on the wall more quickly, such as Figures 1 to 7 As shown, when the installation and fixing structure of the electrical cabinet in the utility model is used, first fix the mounting plate 2 on the wall to be installed, then lift the cabinet 1, and clamp the wall-hanging rod 3 on the top of the cabinet 1 on the L-shaped load-bearing rod 4 on the top of the mounting plate 2, so that the cabinet 1 is hung on the mounting plate 2, and the cabinet 1 and the mounting plate 2 can be quickly connected without alignment, and then the cabinet 1 is connected to the bottom of the mounting plate 2 through the self-locking component, and the installation of the cabinet 1 can be completed, and the installation operation is simpler and faster.

[0027] like Figure 1 - Figure 4 As shown, the wall-hanging rod 3 includes a connecting rod 5 and two fixing blocks 6. The connecting rod 5 is slidably connected to the inner wall of the L-shaped load-bearing rod 4. The two fixing blocks 6 are respectively fixedly connected to the two ends of the connecting rod 5. The ends of the two fixing blocks 5 away from the connecting rod 6 are respectively fixedly connected to the two ends of the top of the cabinet 1 close to the mounting plate 2. When connecting the wall-hanging rod 3 to the L-shaped load-bearing rod 4, the connecting rod 5 is inserted into the L-shaped load-bearing rod 4 from the upper opening of the L-shaped load-bearing rod 4. At this time, the end of the L-shaped load-bearing rod 4 facing the cabinet 1 is inserted into the gap between the cabinet 1 and the connecting rod 5, so that the cabinet 1 is hung on the L-shaped load-bearing rod 4 through the two fixing blocks 6 and the connecting rod 5, completing the preliminary installation connection between the cabinet 1 and the mounting plate 2.

[0028] like Figure 1 - Figure 7As shown, the self-locking assembly includes an L-shaped locking rod 7, a lock shell 8, a self-locking rod 9 and a plurality of self-locking springs 10, one end of the L-shaped locking rod 7 is fixedly connected to the bottom of the cabinet 1 on the side close to the mounting plate 2, the lock shell 8 is fixedly connected to the side of the mounting plate 2 close to the L-shaped locking rod 7, a locking groove 801 is provided on the side of the lock shell 8 close to the L-shaped locking rod 7, the outer wall of the self-locking rod 9 is slidably connected to the inner wall of the locking groove 801, both ends of the plurality of self-locking springs 10 are respectively fixedly connected to the locking groove 801 and the self-locking rod 9, an inclined surface is provided on the side of the self-locking rod 9 away from the mounting plate 2, and the inclined surface is slidably connected to the end of the L-shaped locking rod 7 away from the cabinet 1. After the cabinet 1 is hung on the L-shaped load-bearing rod 4 through the wall-hanging rod 3, the bottom of the cabinet 1 is pushed toward the mounting plate 2. At this time, the L-shaped locking rod 7 at the bottom of the cabinet 1 approaches the self-locking rod 9 and is squeezed by the inclined surface of the self-locking rod 9, thereby squeezing the self-locking rod 9 into the locking groove 801. As the L-shaped locking rod 7 continues to move toward the mounting plate 2, the top of the self-locking rod 9 separates from the L-shaped locking rod 7, and the self-locking spring 10 pushes the self-locking rod 9 from the locking groove 801 to the outside, and the self-locking rod 9 pops out of the locking groove 801 and is stuck on the inner side of the L-shaped locking rod 7, thereby locking the L-shaped locking rod 7 in a limited position, so that the L-shaped locking rod 7 is fixed between the self-locking rod 9 and the mounting plate 2, thereby automatically completing the installation and fixation of the bottom of the cabinet 1.

[0029] like Figure 3 - Figure 7 As shown, the opening of the L-shaped locking rod 7 faces downward, the lock shell 8 is located below the L-shaped locking rod 7, and the self-locking rod 9 is fixedly connected to a pull rod 11 on the side away from the L-shaped locking rod 7. The other end of the pull rod 11 passes through the lock shell 8 and is slidably connected to the lock shell 8. The pull rod 11 is located between a plurality of self-locking springs 10. When the cabinet 1 needs to be removed from the mounting plate 2, the self-locking rod 9 can be pulled downward through the pull rod 11 below the lock shell 8, and the self-locking rod 9 can be completely pulled into the lock groove 801. At this time, the self-locking rod 9 will no longer limit the L-shaped locking rod 7, and the cabinet 1 can be pulled outward to release the connection and fixation at the bottom of the cabinet 1. Then, the cabinet 1 is lifted upward to separate the wall-hanging rod 3 from the L-shaped load-bearing rod 4, and the cabinet 1 can be removed from the mounting plate 2.

[0030] like Figure 5 - Figure 7 As shown, one end of the pull rod 11 away from the lock housing 8 is fixedly connected with a cross bar 12. The cross bar 12 is fixed at the bottom of the pull rod 11, and when the pull rod 11 is pulled, the pull rod 11 can be pulled more conveniently through the cross bar 12.

[0031] like Figure 6 and Figure 7As shown, the locking groove 801 is provided with limiting grooves 802 on both sides. The two sides of the self-locking rod 9 away from the end of the L-shaped locking rod 7 are fixedly connected with limiting blocks 13, and the two limiting blocks 13 are respectively slidably connected with the two limiting grooves 802. When the self-locking rod 9 pops out from the locking groove 801 to the outside through the self-locking spring 10, the connection between the limiting blocks 13 on both sides and the limiting grooves 802 can prevent the self-locking rod 9 from popping out from the locking groove 801, ensuring that the self-locking rod 9 always slides up and down in the locking groove 801, further improving the stability of the self-locking structure.

[0032] like Figure 1 - Figure 7 As shown, a plurality of bolt holes 201 are formed through the side of the mounting plate 2 close to the cabinet 1, and the mounting plate 2 is fixedly connected to the wall by a plurality of bolts respectively passing through the plurality of bolt holes 201. A plurality of bolt holes 201 are formed through the mounting plate 2, and when the mounting plate 2 is fixed to the wall, the bolts can be passed through the bolt holes 201 to be fixed to the wall, which is more convenient to use.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
