[0023] In order to more clearly understand the above-mentioned objects, features, and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0024] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0025] Embodiment 1, as Figures 1-4 shown, the present invention provides a moisture-proof structure for the connection terminal interface inside an electrical appliance, including an interface moisture-proof mechanism 1, and a dehumidification and protection mechanism 2 is fixedly connected to the top of the interface moisture-proof mechanism 1;

[0026] The interface moisture-proof mechanism 1 includes a protection plate 101. On one side of the outer wall of the protection plate 101, two brackets 102 are fixedly connected. Sliding slot holes 103 are opened on the outer surfaces of the two brackets 102. A connecting shaft 104 is movably inserted between the inner surfaces of the two sliding slot holes 103. A moisture-proof cover 105 is fixedly sleeved on the outer surface of the connecting shaft 104. On one side of the outer wall of the moisture-proof cover 105, a pull rod 106 is fixedly connected. A sealing washer 107 is fixedly sleeved on the outer surface of the moisture-proof cover 105. On one side of the outer wall of the protection plate 101, an annular sealing baffle 108 is fixedly connected. A waterproof bolt 109 is movably inserted into the inner surface of the annular sealing baffle 108. An interface terminal protective shell 110 is fixedly sleeved on the outer surface of the waterproof bolt 109. A terminal connection port 111 is fixedly installed on the inner surface of the interface terminal protective shell 110. A connecting rod 112 is fixedly connected to the top of the interface terminal protective shell 110. Four holes 113 are opened on one side of the outer wall of the protection plate 101. Fixed bolts 114 are movably inserted into the inner surfaces of the four holes 113. Connecting sleeves 115 are threadedly connected to the outer surfaces of the four fixed bolts 114.

[0027] The effect achieved by the entire Embodiment 1 is that under the action of the moisture-proof mechanism 1, by fixedly connecting two brackets 102 to one side of the outer wall of the protection plate 101, sliding groove holes 103 are opened on the outer surfaces of the two brackets 102, and a connecting shaft 104 is movably inserted between the inner surfaces of the two sliding groove holes 103. At the same time, a moisture-proof cover 105 is fixedly sleeved on the outer surface of the connecting shaft 104. A pull rod 106 is fixedly connected to one side of the outer wall of the moisture-proof cover 105, and a sealing gasket 107 is fixedly sleeved on the outer surface of the moisture-proof cover 105. An annular sealing baffle 108 is fixedly connected to one side of the outer wall of the protection plate 101. In this way, by pressing the moisture-proof cover 105, the connecting shaft 104 moves along the sliding groove hole 103, and at the same time, the sealing gasket 107 is pressed against the inner surface of the annular sealing baffle 108 to achieve moisture-proof sealing in the case of no terminal insertion. A waterproof bolt 109 is movably inserted into the inner surface of the annular sealing baffle 108. An interface terminal protective shell 110 is fixedly sleeved on the outer surface of the waterproof bolt 109, and a terminal connection port 111 is fixedly installed on the inner surface of the interface terminal protective shell 110. After the terminal is inserted into the interface, the waterproof bolt 109 rebounds and is in close contact with the connecting wire, achieving a sealing effect on the interface, which can effectively prevent moisture, water, etc. from entering the electrical appliance, reducing the risk of short-circuit damage to the circuit and improving the service life of the device.

[0028] Embodiment 2 is as Figures 2-4 shown. The dehumidification and protection mechanism 2 includes a housing 201. Two groups of ventilation holes 202 are opened on the outer surface of the housing 201. A support frame 203 is fixedly sleeved on the outer surface of the housing 201. The top of the connecting rod 112 is fixedly connected to the top of the inner wall of the housing 201. The outer surfaces of the four connecting sleeves 115 are all fixedly connected to the inner surface of the housing 201.

[0029] The effect achieved by the entire Embodiment 2 is that under the combined action of the dehumidification and protection mechanism 2 and the moisture-proof mechanism 1, by fixedly connecting the outer surfaces of the four connecting sleeves 115 to the inner surface of the housing 201, the protection plate 101 and the housing 201 are connected and fixed by using fixing bolts 114. On the contrary, as long as the four fixing bolts 114 are unscrewed, the protection plate 101 can be quickly disassembled to maintain and inspect the internal circuit system. In this way, the convenience and efficiency of maintaining the equipment internally are improved.

[0030] Working principle: During use, two brackets 102 are fixedly connected to one side of the outer wall of the protective plate 101. Slide groove holes 103 are opened on the outer surfaces of the two brackets 102. The connecting shaft 104 is movably inserted between the inner surfaces of the two slide groove holes 103. At the same time, a moisture-proof cover 105 is fixedly sleeved on the outer surface of the connecting shaft 104. A pull rod 106 is fixedly connected to one side of the outer wall of the moisture-proof cover 105. And a sealing gasket 107 is fixedly sleeved on the outer surface of the moisture-proof cover 105. A circular sealing baffle 108 is fixedly connected to one side of the outer wall of the protective plate 101. In this way, by pressing the moisture-proof cover 105, the connecting shaft 104 moves along the slide groove hole 103. At the same time, the sealing gasket 107 is pressed against the inner surface of the circular sealing baffle 108 to achieve moisture-proof sealing in the case of no terminal insertion. A waterproof bolt 109 is movably inserted into the inner surface of the circular sealing baffle 108. An interface terminal protective shell 110 is fixedly sleeved on the outer surface of the waterproof bolt 109. A terminal connection port 111 is fixedly installed on the inner surface of the interface terminal protective shell 110. After the terminal is inserted into the interface, the waterproof bolt 109 rebounds and makes close contact with the connecting wire to achieve the sealing effect at the interface, which can effectively prevent moisture, water, etc. from entering the electrical appliance, reduce the risk of circuit short-circuit damage, and improve the service life of the device. At the same time, under the combined action of the dehumidification and protection mechanism 2 and the moisture-proof mechanism 1, by fixedly connecting the outer surfaces of the four connecting sleeves 115 to the inner surface of the housing 201, the protective plate 101 and the housing 201 are connected and fixed by using the fixing bolts 114. On the contrary, just unscrew the four fixing bolts 114 to quickly remove the protective plate 101 to maintain and check the internal circuit system. In this way, the convenience and efficiency of maintaining the interior of the device are improved.

[0031] The above is only a preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms.
