All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0028] This embodiment provides a technical solution:

[0029] Please refer to Figures 1 - 5 As shown, a compact low-voltage power distribution cabinet with a heat dissipation channel includes a cabinet body 1. An installation cavity 10 is opened on the front end face of the cabinet body 1. Vertical cavities 11 are opened on both the left and right sides of the installation cavity 10. A plurality of connection grooves 110 are opened at the position between the installation cavity 10 and the vertical cavities 11. A transverse cavity 12 communicating with the vertical cavities 11 is opened above the installation cavity 10; an exhaust cavity 13 is opened below the installation cavity 10. A plurality of strip-shaped grooves 130 communicating with the installation cavity 10 are opened at the top of the exhaust cavity 13. Heat dissipation grooves 131 penetrating the cabinet body 1 are opened on both side walls of the exhaust cavity 13; A hollow connection bin 14 is fixed to the top of the cabinet body 1. The connection bin 14 communicates with the transverse cavity 12. Guide rods 140 are fixed to both side walls of the connection bin 14. Limit blocks 141 are fixed to the ends of the guide rods 140. Springs 142 for pressing against sliders 143 are sleeved on the guide rods 140; Sliders 143 are slidably mounted on the guide rods 140. A limit rod 145 is fixed to the top of the slider 143. A limit head 146 is fixed to the top end of the limit rod 145; A top plate 15 is provided above the connection bin 14. Connecting plates 151 are fixed to both side walls of the top plate 15. Through holes 1510 are opened in the connecting plates 151. A limit groove 1511 is opened on one side of the through hole 1510, and the limit rod 145 passes through the limit groove 1511; Two side plates 16 are fixed to the bottom of the top plate 15. The side plates 16 are inserted into the opening of the connection bin 14. A plurality of fixing frames 17 are fixed at the position between the two side plates 16. A dust filter screen 171 is fixed in the opening of the fixing frame 17; A heat dissipation fan 18 is also installed on the top of the top plate 15.

[0030] In this embodiment, a plurality of slots 160 are opened on two opposite end faces of the two side plates 16. Insertion strips 170 are fixed to both side walls of the fixing frame 17, and the insertion strips 170 are in plug-in fit with the slots 160. Through the cooperation of the insertion strips 170 and the slots 160, it is convenient to disassemble and assemble the fixing frame 17 and facilitate the cleaning of the dust filter screen 171.

[0031] In this embodiment, the cross-sectional shape of the fixing frame 17 is in the shape of a square frame, and the fixing frame 17 is tightly adhered to the dust filter screen 171. The square frame design facilitates the installation and fixation of the dust filter screen 171 to the fixing frame 17, and the tightly adhered method has the advantage of firm installation.

[0032] In this embodiment, a dial rod 144 is fixed to the bottom of the slider 143. The dial rod 144 is fixedly connected to the slider 143 by bolts. By means of the dial rod 144, it is convenient to move the slider 143, convenient to adjust the position of the limit head 146, and thus convenient to disassemble and assemble the top plate 15.

[0033] In this embodiment, the diameter of the limiting head 146 is larger than the diameter of the limiting rod 145, and the diameter of the through hole 1510 is larger than the diameter of the limiting head 146. The limiting rod 145 can pass through the limiting groove 1511, and under the restriction of the limiting head 146, the limiting rod 145 cannot be separated from the limiting groove 1511, thereby facilitating the limiting and fixing of the top plate 15.

[0034] In this embodiment, the cross-sectional shape of the connection groove 110 is rectangular, and the plurality of connection grooves 110 are linearly and evenly spaced in the vertical direction. The plurality of rectangular connection grooves 110 facilitates evenly and comprehensively blowing wind into the installation cavity 10, thereby improving the heat dissipation effect and heat dissipation efficiency.

[0035] In this embodiment, the cross-section of the connection compartment 14 is in a square shape, and the connection compartment 14 is fixedly connected to the top of the cabinet 1 by bolts. The square shape is convenient for installing structures such as the side panels 16, and the bolt fixing method ensures the installation stability of the connection compartment 14.

[0036] In this embodiment, the front end of the cabinet 1 is hinged with a cabinet door 19 that can be opened and closed, and the cabinet door 19 is hinged to the cabinet 1 through a hinge. The cabinet door 19 is convenient for closing the inner cavity of the cabinet 1, thereby protecting the components in the installation cavity 10.

[0037] It should be added that the cross-sectional shape of the guide rod 140 in this embodiment is rectangular. This design is conducive to the sliding of the slider 143 along the guide rod 140 and can also prevent the slider 143 from rotating, thereby ensuring the stability of the limit rod 145 and the limit head 146.

[0038] When in use, the user first turns on the power of the heat dissipation fan 18, and the heat dissipation fan 18 starts to work. The airflow passes through the heat dissipation fan 18 and enters between the two side panels 16. At the same time, the airflow passes through multiple dust filters 171, and the dust filters 171 intercept and filter dust and other impurities in the airflow. Then, the filtered airflow passes through the horizontal cavity 12 and enters the vertical cavity 11 on both sides, and is blown into the installation cavity 10 through multiple connecting grooves 110. Under the blowing of the airflow, the components in the installation cavity 10 can be cooled, and the airflow simultaneously enters the exhaust cavity 13 through the strip groove 130 with heat, and is discharged to the outside through multiple heat dissipation grooves 131.

[0039] When it is necessary to take out the dust filter net 171 for cleaning, the user first pushes the lever 144 from both sides towards the middle. The lever 144 drives the slider 143 to slide along the guide rod 140, and the spring 142 is compressed by the slider 143. At this time, the slider 143 drives the limit rod 145 and the limit head 146 to move. The limit rod 145 moves from the limit groove 1511 into the through hole 1510. At this time, the limit head 146 moves to the upper part of the through hole 1510. Next, the user lifts the top plate 15 upwards. The top plate 15 drives the side plate 16 to disengage from the connection bin 14. Finally, the user pushes the fixing frame 17, and the fixing frame 17 can be removed, and then the dust filter net 171 can be cleaned.
