The advantage is that the design of the ventilation openings 3 facilitates air circulation inside the distribution cabinet body 1, and the multiple ventilation openings 3 further improve the air circulation inside the distribution cabinet body 1.

[0032] Specifically, the filter 6 and the mounting bracket 4 are plug-in connected. The guide block 7 has a "T"-shaped cross-section. The filter 6 is located outside the vent 3 and is compatible with the vent 3. The advantage is that, through the cooperation of the guide block 7 and the guide groove 5, the filter 6 can be quickly installed by inserting the guide block 7 into the guide groove 5 during use. The design of the filter 6 prevents dust from accumulating inside the distribution cabinet body 1, thus avoiding affecting the normal operation of the electrical components in the inner shell 12 and extending the service life of the electrical components in the inner shell 12.

[0033] Specifically, fan 9 is adapted to vent 3, and guide plate 10 and guide plate 2 11 divide mounting bracket 4 and other components. Guide plate 10 is adapted to groove 13. The advantage is that, through the cooperation of fan 9 and vent 3, air enters inner shell 12 through vent 3, guide plate 10 and groove 13, which facilitates air circulation inside inner shell 12 and heats the electrical components of inner shell 12.

[0034] Example 2: Figures 2-7 As shown, this is an improvement on the previous embodiment.

[0035] Specifically, the cross-section of the second air guide plate 11 is funnel-shaped, and multiple identical heat dissipation fins 14 are provided, with the multiple heat dissipation fins 14 distributed at equal intervals.

The design of multiple heat dissipation fins 14 further improves the overall heat dissipation performance.

[0036] Specifically, the sealing ring 16 is a rubber sealing gasket, and the soft magnet 18 and the soft magnet 20 are magnetically connected. The advantage is that, because the rubber sealing gasket has high sealing performance, when the cabinet door 2 is closed, the soft magnet 18 and the soft magnet 20 attract each other, making the connection between the cabinet door 2 and the power distribution cabinet body 1 tighter, and the overall sealing performance is high.

[0037] Specifically, the locking assembly 21 includes a slot 2101, a movable groove 2102, a sliding block 2103, a spring 2105, a limiting block 2106, a pull rod 2107, an insert block 2108, and a limiting groove 2109. The outer surface of the distribution cabinet body 1 is provided with a slot 2101 and a movable groove 2102. The inner surface of the movable groove 2102 is provided with a sliding block 2103. The outer surface of the sliding block 2103 is fixedly installed with a spring 2105. The end of the sliding block 2103 away from the spring 2105 is fixedly installed with a limiting block 2106. The outer surface of the sliding block 2103 is fixedly installed with a pull rod 2107. The side of the cabinet door 2 closest to the distribution cabinet body 1 is fixedly installed with an insert block 2108. The outer surface of the insert block 2108 is provided with a limiting groove 2109. The cross-section of the limiting block 2106 is trapezoidal. The limiting block 2106 is adapted to the limiting groove 2109. The advantages are that when the operator rotates the cabinet door 2, the insert 2108 is inserted into the slot 2101. When the insert 2108 contacts the limit block 2106, the limit block 2106 moves upward, and the spring 2105 is compressed and contracts. When the insert 2108 is completely submerged in the slot 2101, the spring 2105 rebounds, pushing the limit block 2106 into the limit groove 2109, which can quickly lock the cabinet door 2. When it is necessary to open the cabinet door 2, simply pull the lever 2107 to move the limit block 2106 upward, and then pull the insert 2108 out of the slot 2101, which can quickly open the cabinet door 2. Through the design of the locking component 21, after long-term use, the door lock 22 is prevented from being damaged. The aging of the connecting shaft between the cabinet door 2 and the power distribution cabinet body 1 can cause the cabinet door 2 to loosen when closed, affecting the normal use of the whole. It has high practicality.

[0038] Working principle: During installation, the guide block 7 and guide groove 5 cooperate. During use, the operator inserts the guide block 7 into the guide groove 5, enabling quick installation of the filter screen 6. The design of the filter screen 6 prevents dust accumulation inside the distribution cabinet body 1, thus avoiding impact on the normal operation of the electrical components in the inner shell 12 and extending their lifespan. During use, the operator first connects the external power supply. When it is necessary to close the cabinet door 2, the operator rotates the cabinet door 2 while inserting the guide block 7. Insert 2108 into slot 2101. When insert 2108 contacts limit block 2106, limit block 2106 moves upward, and spring 2105 is compressed and contracts. When insert 2108 is fully submerged in slot 2101, spring 2105 rebounds, pushing limit block 2106 into limit groove 2109, thus quickly locking cabinet door 2. To open cabinet door 2, simply pull lever 2107 to move limit block 2106 upward, and then insert 2108 into slot 2109. Pulling out the slot 2101 allows for quick opening of the cabinet door 2. The locking component 21 prevents damage to the door lock 22 after prolonged use. Aging of the connecting shaft between the cabinet door 2 and the main body 1 can cause the cabinet door 2 to loosen when closed, affecting normal operation. The rubber sealing gasket provides high sealing performance; when the cabinet door 2 is closed, the soft magnet 18 and soft magnet 20 attract each other, making the connection between the cabinet door 2 and the main body 1 tighter and improving overall sealing performance. Through the cooperation of the fan 9 and the vent 3, air enters the inner shell 12 through the vent 3, the guide plate 10, and the groove 13, facilitating airflow within the inner shell 12 and providing heat dissipation for the electrical components. Simultaneously, air contacts the heat dissipation fins 14 through the vent 3 and the guide plate 11, allowing for rapid cooling and high heat dissipation performance. The design of multiple heat dissipation fins 14 further enhances the overall heat dissipation performance.
