as shown in fig. 11, the fixing frame 41 drives the second connecting rod 65 to move up and down during the movement, then the second connecting rod 65 drags the first closing plate 63 to move up and down along the rail strip 62 through the connecting plate 64, when the cabinet 2 is in the moving mode, it can be understood that the cabinet 2 is in the non-working state at this time, the internal electrical appliance of the cabinet 2 is no longer used at this time, and no heat is generated, the falling first closing plate 63 blocks the channel of the first heat dissipation hole 61, so as to prevent the entry of dust and insects, and avoid pollution and damage to the electrical appliance, furthermore, the connecting plate 64 moves to shift the position of the proximity sensor 67 during the movement, the proximity sensor 67 sends a signal of disconnecting the circuit to the control circuit, so as to play a role of safety, only when the cabinet 2 is in the fixed state and the first heat dissipation hole 61 is opened, at this time, the connecting plate 64 drives the proximity sensor 67 to reset, and the circuit is conducted again, so as to play a safety role of safety electricity utilization; as shown in fig. 7, a first extending plate 82 is arranged on the cabinet door 81, a second extending plate 83 is correspondingly arranged on the cabinet body 2, the opposite curved surfaces of the first extending plate 82 and the second extending plate 83 are synchronous, a rubber tube 84 is arranged inside the second extending plate 83, the rubber tube 84 is filled with air, and the rubber tube 84 is pressed when the first extending plate 82 and the second extending plate 83 contact with each other, so that the rubber tube 84 collides to better block the gap between the two, and a good sealing effect is achieved; as shown in fig. 8-9, when the cabinet door 81 is closed, the cabinet door first contacts the rubber block 97, then the force is transmitted to the second sliding rod 95, then the second sliding rod 95 causes the third connecting rod 92 to deflect through the fourth connecting rod 96, due to the reset action of the second torsion spring 93, the rubber block 97 can have a reaction force, so that the closing force of the cabinet door 81 is delayed, the cabinet door 81 is prevented from impacting the cabinet body 2, the third connecting rod 92 pushes the third sliding rod 98 to move through the fifth connecting rod 99 when deflecting, so that the third sliding rod 98 moves towards the inside of the limiting sleeve 993, until the second fixture block 991 pops out of the clamping limiting sleeve 993, at this moment, the cabinet door 81 is in limiting fit with the cabinet body 2, under the limiting of the second torsion spring 93, the third sliding rod 98 has a tendency to shrink towards the inside of the cabinet body 2, so that the cabinet door 81 is pulled to be closer to the cabinet body 2, the sealing performance between the cabinet door 81 and the cabinet body 2 is further improved, the waterproof performance of the switch cabinet door 81 is improved, when the limiting of the limit of the switch is released, the key rotates the lock body 994, the second lock body 991 is pushed into the limiting sleeve 98, and the third sliding rod 993, so that the third sliding rod 993 is only need to push the limiting sleeve 98; when heat dissipation is performed, as shown in fig. 10, the active fan 73 is turned on, air enters from the second heat dissipation hole 71, and is guided into the inside of the cabinet body 2 through the ventilation pipe 72, and then hot air is guided out from the first heat dissipation hole 61, because the density of cold air is greater than that of hot air, the cold air is located below the hot air, the second heat dissipation hole 71 is located at the bottom end of the first heat dissipation hole 61, so that the distribution characteristic of the cold air and the hot air is better utilized to guide the cold air into the inside of the cabinet body 2, and then the hot air carrying heat is discharged through the first heat dissipation hole 61, so as to improve the heat dissipation effect of the switch cabinet, in addition, the ventilation pipe 72 is provided with a relatively high length, only when the height of external water flow is higher than the ventilation pipe 72, soaking can be caused, and the waterproof performance of the switch cabinet is improved.
