Detailed Embodiment

[0018] The following combines the drawings and embodiments to describe the utility model in detail.

[0019] A heat-dissipating distribution box convenient for maintenance, as Figures 1-4As shown in the figure, it includes a box body 1 and a box door 2 that are rotatably connected to each other. A bracket 3 and an air outlet fan 4 are arranged inside the box body 1. An installation rack 5, a filter net 6, and several air inlet fans 7 are fixedly arranged on the box door 2. The air outlet fan 4 and the air inlet fans 7 arranged on the box door 2 and the box body 1 are used to form the flow of air. In this state, the equipment arranged in the weak current box can obtain sufficient heat dissipation to avoid the situation of overheating of the equipment. A lid 8 is rotatably arranged on the box door 2. A fixing part that can be fixed on the box body 1 is arranged on the lid 8. The setting of the lid 8 is used to form the connection of the circuit between the air outlet fan 4 and the air inlet fans 7. The user needs to close the box door 2 and only when the lid 8 is covered in its designated position can the air outlet fan 4 and the air inlet fans 7 be powered on and operate. Wires 9 are arranged on both the air inlet fans 7 and the air outlet fan 4 and respectively penetrate through the lid 8 and the box body 1. Connecting parts 10 are arranged on both the lid 8 and the box body 1. The connection and separation of the circuit between the lid 8 and the box body 1 are formed by the connecting parts 10 to conduct electricity. A plurality of ventilation holes 11 are opened on the box door 2. The setting of the ventilation holes 11 is used to form the flow of air. A power supply 12 is arranged inside the box body 1. The connecting part 10 includes an insulating shell 13 and a conductive plate 14. A pressing piece 15 that abuts against the wire 9 is arranged on the conductive plate 14. A contact point 16 is arranged on the conductive plate 14. The two connecting parts 10 are electrically connected through the contact point 16. The air inlet fans 7 and the air outlet fan 4 are connected through the wire 9 and operate under the condition of being powered on. The circuit from the power supply 12 to the air inlet fans 7 and the air outlet fan 4 passes through the box body 1 and the box door 2 and is guided to the conductive plate 14 in the connecting part 10. When the box door 2 is closed on the box body 1 and the user buckles the lid 8 on the box door 2 so that the two connecting parts 10 are in mutual abutment, the contact points 16 on the two connecting parts 10 correspondingly abut against each other, and the current flows through the contact point 16 to realize the driving of the air inlet fans 7 and the air outlet fan 4. When the box door 2 is opened, the lid 8 moves with the box door 2, and the disconnection of the contact points 16 between the two connecting parts 10 can be realized.

[0020] The fixing part is set as a magnet 17. A magnetic attracting sheet 18 is adhesively connected to the box body 1 in the area close to the lid 8. The lid 8 is fixed on the box body 1 through the mutual attraction between the magnet 17 and the magnetic attracting sheet 18. The setting of the magnet 17 and the magnetic attracting sheet 18 is used to fix the position of the lid 8 when the user returns the lid 8 after the box door 2 is closed. An abutting piece 19 that can abut against the lid 8 is arranged on one side of the box door 2 close to the box body 1. The abutting piece 19 forms the position limitation of the lid 8 on the box door 2. An elastic piece 20 is fixedly arranged on the box door 2. The elastic piece 20 abuts against the lid 8. The setting of the elastic piece 20 is used to enable the lid 8 to automatically pop open when the user controls the opening of the box door 2, so as to timely disconnect the contact of the contact points 16 between the two connecting parts 10, and make the air inlet fans 7 and the air outlet fan 4 still in the power-off state when the user closes the door, and form a reconfirmation of the fixation of the box door 2 through the buckling of the lid 8.

[0021] An air outlet passage 21 is formed between the bracket 3 and the box body 1. The air outlet passage 21 is arranged at the top of the box body 1 and can form an air flow effect on a deeper position of the box body 1.

[0022] Working principle: When the box door 2 is closed, the fixing member forms the position fixation of the lid 8 through the magnetic attraction effect between the magnet 17 and the magnet-attracting sheet 18 provided thereon, and thereby makes the contact points 16 between the connecting member 10 on the lid 8 and the connecting member 10 on the box body 1 keep the connection state, so that the intake fan 7 and the exhaust fan 4 keep running. When the user opens the box door 2, the lid 8 on the box door 2 moves along with the box door 2 driven by the abutting piece 19 and is pushed by the elastic piece 20, and extends out of the box door 2 through the rotational connection with the box door 2. At this time, the contact points 16 between the two connecting members 10 are disconnected, and the intake fan 7 and the exhaust fan 4 are not powered and stop running. Then the user can install and operate the equipment inside the box body 1. After the user closes the box door 2, the lid 8 needs to be manually reset. When the lid 8 is reset, the magnet 17 and the magnet-attracting sheet 18 attract each other, driving the lid 8 to fit towards the box body 1. During this process, the contact points 16 on the two connecting members 10 resume the state of abutting against each other, so that the circuit from the power supply 12 to the intake fan 7 and the exhaust fan 4 is restored, and the intake fan 7 and the exhaust fan 4 resume running.
