Detailed Implementation
[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0020] This application discloses a waterproof structure for a digital display charger, referring to... Figure 1 , Figure 2 and Figure 3 The charger includes a main body, which comprises a housing 1 and an operation panel 2 and a wiring panel 21 disposed inside the housing 1. An operation port 11 is provided on one side of the housing 1 corresponding to the operation panel 2, and a wiring port 12 is provided on one side of the housing 1 corresponding to the wiring panel 21. A first baffle 3 for opening / closing the operation port 11 and a second baffle 4 for opening / closing the wiring port 12 are installed on the outer wall of the housing 1. A first notch is provided on one side of the second baffle 4, and a second notch is provided on the inner wall of one side of the wiring port 12. The first and second notches together form a wire hole 5 with a size adapted to the wire.
[0021] In this embodiment, the operation panel 2 is equipped with a display screen and buttons, and the wiring panel 21 is equipped with connectors. The side walls of the housing 1 corresponding to the operation panel 2 and the wiring panel 21 are made of transparent material. The operator can open the second baffle 4 to pass the wire through the wiring port 12 and connect it to the connector; the operator can open the first baffle 3 to press the button to operate. By closing the operation port 11 with the first baffle 3 and the wiring port 12 with the second baffle 4, and by ensuring that the wire hole 5 is compatible with the wire, water can be prevented from entering the housing 1 during charging, thus improving the safety of the charger.
[0022] Furthermore, the first baffle 3 is rotatably disposed at the operating port 11, with the pivot of the first baffle 3 located at the bottom of the operating port 11, and the movable end of the first baffle 3 movably abutting against the inner top wall of the operating port 11; the second baffle 4 is rotatably disposed at the wiring port 12, with the pivot of the second baffle 4 located at the bottom of the wiring port 12, and the movable end of the second baffle 4 movably abutting against the inner bottom wall of the wiring port 12, and the first notch is disposed at the movable end of the second baffle 4; both the pivot of the first baffle 3 and the second baffle 4 are fitted with torsion springs 6 for driving their movable ends to rotate to the top of the corresponding operating port 11 / wiring port 12.
[0023] In this embodiment, the pivot of the first baffle 3 / second baffle 4 and the torsion spring 6 are both located inside the housing 1. When the operator pushes the first baffle 3 / second baffle 4 into the housing 1, the corresponding operation port 11 / connection port 12 can be opened. After the operation is completed, the operator can withdraw his hand, and the first baffle 3 / second baffle 4 can rotate on its own under the action of the torsion spring 6 and close the corresponding operation port 11 / connection port 12.
[0024] To improve the waterproofing effect of the first baffle 3 and the second baffle 4, waterproof gaskets 7 are provided on the inner walls of the operating port 11, the wiring port 12, the first notch, and the second notch. The waterproof gaskets 7 are made of rubber.
[0025] To facilitate the handling of the charger body by staff, two carrying handles 8 are rotatably installed on the outer wall of the casing 1.
[0026] Furthermore, the movable ends of both carrying frames 8 are welded with multiple support blocks 81 for supporting the housing 1 when rotated to the bottom of the housing 1, and the carrying frames 8 are equipped with limiting members 9 for restricting their own rotation relative to the housing 1 when the support blocks 81 support the housing 1.
[0027] When the charger body is transported to the work site, the worker can rotate the carrying frame 8 and ground the support block 81 to support the housing 1. Then, the rotation of the carrying frame 8 needs to be restricted by the limiting component 9. By supporting the housing 1 with the support block 81, the housing 1 can be suspended in the air, avoiding water accumulation at the work site from contaminating the housing 1.
[0028] Reference Figure 4 The limiting component 9 includes a limiting post 91, which is slidably mounted on the carrying frame 8 in a direction parallel to the rotation axis of the carrying frame 8. A pull rod is coaxially welded to one end of the limiting post 91, and the end of the pull rod away from the limiting post 91 moves through the carrying frame 8 and is fixedly connected to a handle. A spring 92 is sleeved on the pull rod, and the two ends of the spring 92 abut against the limiting post 91 and the carrying frame 8 respectively. A limiting groove 13 is provided on the outer wall of the housing 1 below the carrying frame 8 for the limiting post 91 to be inserted.
[0029] As the support block 81 rotates to the bottom of the housing 1, the limiting post 91 can move and align with the limiting groove 13. Under the elastic force of the spring 92, one end of the limiting post 91 is inserted into the limiting groove 13, thereby achieving the purpose of limiting the rotation of the handle 8.
[0030] Furthermore, the bottom of the housing 1 has multiple heat dissipation holes 14, and a breathable moisture-proof pad 10 is provided inside the housing 1 at the heat dissipation holes 14. The moisture-proof pad 10 can be made of sponge.
[0031] The implementation principle of the waterproof structure of the digital display charger in this embodiment is as follows: The operator opens the second baffle 4 to pass the wire through the connection port 12 and connect it to the connector; the operator opens the first baffle 3 to press the button for operation. By closing the operation port 11 with the first baffle 3 and the connection port 12 with the second baffle 4, and by ensuring the wire hole 5 is compatible with the wire, water can be prevented from entering the housing 1 during charging, thus improving the safety of the charger.
