[0019] Embodiment one

[0020] Please refer to Figures 1-2 The utility model discloses a kind of fully-enclosed waterproof power adapter 1.A kind of fully-enclosed waterproof power adapter, including upper shell 1, the bottom end surface of upper shell 1 is equipped with rubber pad 3, the outer side surface of rubber pad 3 is equipped with lower shell 2, the top end surface of upper shell 1 is equipped with mounting hole 4, the inner wall of mounting hole 4 is equipped with fixed screw 5, the inner wall top end surface of lower shell 2 is equipped with mounting pipe 6, one side of mounting pipe 6 is provided with insulation pad 7, the top end surface of insulation pad 7 is equipped with protective shell 8, the inner wall of protective shell 8 is equipped with reinforcing assembly, reinforcing assembly includes fixed plate 9, first cavity 11 is provided between protective shell 8 and upper shell 1, the bottom end surface of fixed plate 9 and the inner wall bottom end surface of protective shell 8 are provided with second cavity 12.

[0021] The bottom end surface of upper shell 1 and the top end surface of lower shell 2 are in contact with each other, the outer side surface of rubber pad 3 and the top end surface of lower shell 2 are fixedly connected with each other, the outer side surface of rubber pad 3 and the bottom end surface of upper shell 1 are in movable contact with each other, mounting hole 4 is four rectangular arrays on the top end surface of upper shell 1, and one fixed screw 5 is arranged on the inner wall of each mounting hole 4.

[0022] The outer side surface of fixed screw 5 and the inner wall of mounting hole 4 are movably and rotatably connected with each other, one mounting pipe 6 is arranged on the outer side surface of each fixed screw 5, the inner wall of each mounting pipe 6 and the outer side surface of fixed screw 5 are movably and rotatably connected with each other, the bottom end surface of each mounting pipe 6 and the inner wall top end surface of lower shell 2 are fixedly connected with each other, there are four insulation pads 7, two insulation pads 7 form a group, two groups of insulation pads 7 are symmetrically arranged, and one protective shell 8 is fixedly arranged on the top end surface of each group of insulation pads 7.

[0023] Water first contacts the gap between the first and second shells that are in close contact with each other, and as the gap contacts the rubber pad 3 between the upper shell 1 and the lower shell 2, if the pressure of the water cannot pass through the gap between the upper shell 1 and the lower shell 2, the protection is completed, and if it passes through the gap, it will enter the inner wall of the upper shell 1 and the lower shell 2.

[0024] Example two

[0025] Based on the above example 1, please refer to Figures 3-4 The fixed plate 9 is installed on the inner wall of the protective shell 8, the top surface of the fixed plate 9 is provided with an adapter main body 10, and the two sides of the protective shell 8 are provided with an electricity inlet 13 and an electricity outlet 14.

[0026] The inner wall of each protective shell 8 is provided with a fixed plate 9, and the two fixed plates 9 are provided with an adapter main body 10, and the fixed plate 9 and the inner wall bottom surface and the inner wall top surface of the protective shell 8 form a second cavity 12.

[0027] The side surface of the electricity inlet 13 is fixedly connected with the side surface of the protective shell 8, the outer side surface of the electricity inlet 13 is movably connected with the inner wall of the upper shell 1 and the lower shell 2, the side surface of the electricity outlet 14 is fixedly connected with the side surface of the protective shell 8, and the outer side surface of the electricity outlet 14 is movably connected with the upper shell 1 and the lower shell 2.

[0028] The installation pipe 6 is fixedly connected with the lower shell 2, although the fixed screw 5 is tightly fitted between the upper shell 1 and the lower shell 2 through cooperation with the installation pipe 6, the inner wall is not damaged because the threads of the inner wall are not directly fixed by the fixed screw 5, if liquid is retained, it will not flow into the shell through the joint gap of the shell, and when it flows into the shell, because the first cavity 11 is arranged in the inner wall, the liquid will not directly contact the inner wall of the protective shell 8.

[0029] The working principle and use process of the utility model are as follows: when water passes through the upper shell 1 and the lower shell 2 of the full-closed waterproof power adapter, the water first contacts the gap between the first and second shells that are in close contact with each other, and as the gap contacts the rubber pad 3 between the upper shell 1 and the lower shell 2, if the pressure of the water cannot pass through the gap between the upper shell 1 and the lower shell 2, the protection is completed, and if it passes through the gap, it will enter the inner wall of the upper shell 1 and the lower shell 2.

[0030] At this time, the water enters the inner wall formed between the upper shell 1 and the lower shell 2, and the water will contact each other between the installation pipe 6 and the installation pipe 6. However, since the installation pipe 6 and the lower shell 2 are fixedly connected with each other, although the fixed screw 5 tightly fits the upper shell 1 and the lower shell 2 by cooperating with the installation pipe 6, the inner wall is not damaged since the threads of the inner wall are not directly fixed between the upper shell 1 and the lower shell 2 by the fixed screw 5. If the liquid remains, it will not flow into the shell through the joint gap of the shell. When flowing into the shell, since the inner wall is provided with the first cavity 11, the liquid will not directly contact the inner wall of the protective shell 8. The liquid will slowly accumulate. If the connection between the protective shell 8 penetrates due to the pressure of the liquid, the adapter main body 10 fixed by the inner wall fixed plate 9 will be installed in the middle of the protective shell 8, so as to isolate the adapter main body 10 and the protective shell 8, and the second cavity 12 is formed. At this time, the third waterproof measure is completed.
