DETAILED DESCRIPTION

[0019] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as: above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as: first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0020] Embodiment: An embedded electrical switch cabinet, such as Figure 1-Figure 5 As shown, it includes a fixed frame 1, an electrical switch cabinet body 2, a connecting frame 3, an exhaust fan 4 and a filter 5. A convex portion 10 is provided at the bottom of the fixed frame 1, and a plurality of air inlet holes 11 are opened at the front of the fixed frame 1. Air enters the fixed frame 1 from the air inlet holes 11. The electrical switch cabinet body 2 is arranged in the fixed frame 1. A slide groove 21 is opened at the lower part of the electrical switch cabinet body 2. The convex portions 10 slide in the slide groove 21. A card groove 22 and a plurality of through holes 23 are opened on both sides of the upper part of the electrical switch cabinet body 2. Air enters the electrical switch cabinet body 2 from the fixed frame 1 through the through holes 23. A connecting frame 3 is installed on the upper part of the fixed frame 1. The lower end of the connecting frame 3 is connected to the electrical switch cabinet body 2. An exhaust fan 4 is installed in the connecting frame 3, and a filter 5 is installed at the front of the connecting frame 3.

[0021] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, it also includes a limiting mechanism, which includes a limiting block 61, a compression spring 62, an extrusion frame 63 and a return spring 64. The left and right sides of the inner wall of the fixed frame 1 are slidably connected to the limiting blocks 61. The limiting blocks 61 are all located in the card slot 22. The upper side and the front side of the limiting block 61 are both inclined. Please refer to Figure 5 A compression spring 62 is fixedly connected between the limit block 61 and the fixed frame 1, an extrusion frame 63 is slidably connected to the upper part of the fixed frame 1, two return springs 64 are fixedly connected between the extrusion frame 63 and the fixed frame 1, and an inclined portion 65 is provided at the lower part of the extrusion frame 63. The extrusion frame 63 will squeeze the limit block 61 when it moves downward.

[0022] When the electrical switch cabinet body 2 is installed in the fixed frame 1, the exhaust fan 4 is controlled, and air can enter the electrical switch cabinet body 2 from the air inlet 11 and the through hole 23, and the air can then absorb the heat generated by the electrical components inside the electrical switch cabinet body 2, thereby cooling the electrical switch cabinet body 2, and then through the action of the exhaust fan 4, the air enters the connecting frame 3 from the inside of the switch cabinet body, and then is discharged from the connecting frame 3, thereby continuously circulating the air in the electrical switch cabinet body 2, and can continuously dissipate heat and cool the electrical switch cabinet body 2, thereby preventing the electrical switch cabinet body 2 from overheating and causing a malfunction. The filter 5 at the front of the connecting frame 3 can block external dust, preventing dust from entering the electrical switch cabinet body 2 and affecting its normal operation.

[0023] When the electrical switch cabinet body 2 is to be disassembled and repaired, the extrusion frame 63 is first pushed downward to compress the reset spring 64. The extrusion frame 63 moves downward to squeeze the limit block 61. Since the upper sides of the limit blocks 61 are all inclined, the extrusion frame 63 moves downward to make the two limit blocks 61 slide in the direction away from each other, the compression spring 62 is compressed, and the limit blocks 61 will all be separated from the card slot 22. At this time, the limit block 61 no longer limits the electrical switch cabinet body 2. Then, the electrical switch cabinet body 2 is manually pulled, and the electrical switch cabinet body 2 slides forward along the protrusion 10, thereby pulling the electrical switch cabinet body 2 out of the fixed frame 1, so that the electrical switch cabinet can be quickly loaded and unloaded, which is convenient for the staff to repair the electrical switch cabinet. Then, the extrusion frame 63 is released, the reset spring 64 is restored, and the extrusion frame 63 moves upward to return to its original position. At this time, the inclined portion 65 of the extrusion frame 63 no longer squeezes the limit block 61, and the compression spring 62 is restored, thereby making the two limit blocks 61 move to their original positions in the direction of approaching each other.

[0024] The electrical switch cabinet body 2 can be pulled out of the fixing frame 1 for maintenance. When the electrical switch cabinet body 2 is repaired, the slide groove 21 on the lower side of the electrical switch cabinet body 2 is aligned with the protrusion 10 on the fixing frame 1, and then the electrical switch cabinet body 2 is pushed so that the electrical switch cabinet body 2 slides backward along the protrusion 10 to return to its original position. The electrical switch cabinet body 2 slides backward and squeezes the limit block 61. Since the front sides of the limit blocks 61 are all inclined, the two limit blocks 61 move in the direction away from each other. At this time, the compression spring 62 is compressed. When the electrical switch cabinet body 2 continues to slide backward, the limit block 61 will meet the adjacent slot 22. At this time, the electrical switch cabinet body 2 no longer squeezes the limit block 61, and the compression spring 62 is restored. At this time, the two limit blocks 61 move in the direction close to each other, and the limit block 61 will then be stuck in the slot 22, thereby fixing the electrical switch cabinet body 2 in the fixing frame 1.

[0025] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the utility model concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
