[0036] Example 1

[0037] like Figure 1-6 As shown, a power switching box proposed by the present invention includes a box body 1, a connecting component 2, a cooling fan 4, a supporting component 5 and a limiting component 6;

[0038] The support assembly 5 is installed at the inner bottom of the box body 1, and the limit assembly 6 is installed at the inner top of the box body 1, and the support assembly 5 and the limit assembly 6 are arranged opposite to each other;

[0039] The connecting component 2 is installed between the supporting component 5 and the limiting component 6 to fix the power switch 3 in the installed state and move it to the inner side of the box 1;

[0040] The cooling fans 4 are installed on both sides of the interior of the box 1 and face the outside of the box 1. Shutters are provided on both sides of the box 1 and on both sides of the power switch 3. There are at least two cooling fans 4, which are respectively installed at the shutters of the box 1 to discharge the heat generated by the power switch 3 when in use.

[0041] In this embodiment, the power switch 3 is slidably installed on the connecting component 2, and the connecting component 2 is fixed to it. At the same time, the connecting component 2 is moved to the inner side of the box body 1, and the top end of the connecting component 2 is placed below the limit component 6, so that the bottom end of the limit component 6 moves upward, the distance between the support component 5 and the limit component 6 is increased, and the bottom end of the connecting component 2 is moved toward the inner side of the support component 5, so that the connecting component 2 is placed on the inner side of the support component 5. The support component 5 and the limit component 6 cooperate to fix the connecting component 2 on the inner side of the box body 1, so that the installation of the power switch 3 is more convenient and quick.

[0042] Example 2

[0043] like Figure 6 As shown, the power switching box proposed by the present invention, compared with the first embodiment, in this embodiment, the connection component 2 includes a connection plate 21 and a connection block 24;

[0044] The connecting plate 21 is placed inside the supporting assembly 5 and the limiting assembly 6. Through holes are provided on both sides of the bottom of the end surface of the connecting plate 21. One end of the supporting assembly 5 is inserted into the inner side of the through hole to adjust the position of the connecting plate 21 when in use, thereby preventing the connecting plate 21 from falling off.

[0045] The connecting block 24 is installed on the end face of the connecting plate 21. It should be noted that the connection between the connecting block 24 and the connecting plate 21 is not limited to direct connection, and can be connected by bolt fixing. There are slide grooves at the upper and lower ends inside for sliding the power switch 3 on the inner side of the connecting block 24 when in use and for limiting the position of the power switch 3 in the upper, lower and left directions. The size of the slide groove is used in conjunction with the size of the mounting plate of the power switch 3.

[0046] In an optional embodiment, a stopper 23 and a screw 22 are further included;

[0047] The stopper 23 is mounted inside the slot of the connecting block 24 and contacts the power switch 3. Both ends of the stopper 23 are located inside the slot of the connecting block 24. Therefore, the stopper 23 can be slid synchronously with the power switch 3 inside the slot of the connecting block 24 to block the lateral movement of the power switch 3.

[0048] The screw 22 is installed on the end surface of the stopper 23 and one end is inserted into the stopper 23 and the connecting plate 21 for fixing the stopper 23 to the inner side of the slide groove of the connecting block 24 in the use state, so that the stopper 23 has resistance to block the power switch 3.

[0049] Example 3

[0050] like Figure 5 and Figure 3 As shown, the power switching box proposed by the present invention, compared with the first embodiment, in this embodiment, the support assembly 5 includes a support block 51;

[0051] The support block 51 is mounted on the inner wall of the box 1 , and one end of the support block 51 has a step with both ends blocked, and the step and the box 1 support form a groove for placing the bottom end of the connecting component 2 in use.

[0052] In an optional embodiment, it further includes a locking rod 52, a spring A53 and a connecting cap 54;

[0053] The connecting cap 54 is mounted on the side of the supporting block 51;

[0054] The locking rod 52 is arranged on the inner side of the connecting cap 54, and one end passes through the connecting cap 54, and the other end passes through the support block 51 and is connected to the connecting component 2; the other end of the locking rod 52 has an upward inclined surface. When the connecting component 2 is installed to the inner side of the support block 51, the locking rod 52 is moved toward the connecting cap 54 through the inclined surface, and the locking rod 52 compresses the spring A53. When there is a gap between the through hole of the connecting component 2 and the bottom edge of the end of the locking rod 52, the spring A53 rebounds and inserts the other end of the locking rod 52 into the inner side of the through hole of the connecting component 2 to fix the connecting component 2.

[0055] The spring A53 is sleeved on the outside of one end of the locking rod 52 and its two ends are respectively connected to the connecting cap 54 and the locking rod 52 for moving the other end of the locking rod 52 to the inside of the support block 51 and limiting the connecting assembly 2 when in use.

[0056] Example 4

[0057] like Figure 3-4 As shown, the power switching box proposed by the present invention, compared with the first embodiment, in this embodiment, the limiting assembly 6 includes a limiting block 61, a spring B62 and a telescopic sleeve 63;

[0058] The telescopic sleeve 63 is installed at the inner top end of the box body 1 , and its telescopic distance is greater than the height of the limit block 61 .

[0059] The limit block 61 is mounted at the bottom end of the telescopic sleeve 63 and is L-shaped. The limit block 61 can only move up and down due to the limitation of the telescopic sleeve 63. When the limit block 61 is connected to the connecting component 2, the connecting component 2 is limited to move forward and backward according to the shape of the limit block 63.

[0060] The spring B62 is arranged on the inner side of the telescopic sleeve 63 and its two ends are respectively connected to the inner top end of the telescopic sleeve 63 and the limit block 61 so that the limit block 61 is always in contact with the connecting component 2 and limits the position when in use.

[0061] In summary, when the present invention is in use, the power switch 3 is slidably installed on the inner side of the connecting block 24, the stopper 23 is synchronously installed on the inner side of the connecting block 24 and the stopper 23 is fixed to the connecting plate 21 by the screw 22, so that the stopper 23 blocks the opening of the connecting block 24, so that the power switch 3 is fixed to the inner side of the connecting block 24, and the connecting plate 21 is moved to the inner side of the box body 1, so that the top end of the connecting plate 21 is connected to the limit block 61, and the limit block 61 is moved upward to compress the spring B62, so that the distance between the limit block 61 and the support block 51 is greater than the length of the connecting plate 21, so that the bottom end of the connecting plate 21 is placed between the support block 51 and the box body 1 The inner side of the groove formed between the connecting plate 21 and the supporting block 51 allows the connecting plate 21 to be installed on the inner side of the box body 1. At the same time, when the connecting plate 21 moves toward the inner side of the supporting block 51, the connecting plate 21 contacts the inclined surface of the locking rod 52 and moves the locking rod 52 toward the connecting cap 54 through the inclined surface. The locking rod 52 compresses the spring A53, and when there is a gap between the through hole of the connecting component 2 and the bottom edge of the end of the locking rod 52, the spring A53 rebounds and inserts the other end of the locking rod 52 into the inner side of the through hole of the connecting component 2 to fix the connecting component 2, making the installation of the power switch 3 more convenient and quick. When in use, the cooling fan 4 is started to discharge the heat generated by the power switch 3 to the outside through the shutters of the box body 1.

[0062] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
