Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Example 1: Figure 1-Figure 4 As shown, the utility model provides a multi-output power adapter, including a shell 1, the outer wall of the shell 1 is provided with four installation slots 2, the inner walls of the four installation slots 2 are provided with limit springs 4, the inner walls of the four installation slots 2 are movably embedded with limit plates 3, and one side of the outer wall of the limit plate 3 is fixedly connected to one side of the outer wall of the limit spring 4, the outer wall of the shell 1 is provided with two insertion slots 7, the top of the shell 1 is provided with a top cover 8, and the outer wall of the top cover 8 is movably inserted in the inner part of the insertion slot 7, and the top cover 8 is The outer wall is provided with four limit grooves 9, the outer wall of the top cover 8 is provided with four square grooves 10, the inner walls of the four square grooves 10 are provided with compression springs 11, and the outer wall side of the four compression springs 11 is fixedly installed with a limit rod 12, and the outer wall side of the outer wall of the outer shell 1 is provided with a fixing groove 17, the inner wall of the fixing groove 17 is provided with a mounting plate 18, and the inner wall of the mounting plate 18 is movably inserted with four fixing bolts 19, and the outer wall of the mounting plate 18 is connected to the inner wall of the fixing groove 17 by the fixing bolts 19.

[0024] The effect achieved by the entire embodiment 1 is that when the electronic components inside the power adapter are damaged, first, under the operation of the staff, the limit spring 4 is pressed to drive the limit plate 3 to move to both sides inside the installation groove 2, so that the limit plate 3 is taken out from the limit groove 9, so that it no longer plays a fixed limiting role on the top cover 8, and then under the operation of the staff, the compression spring 11 inside the square groove 10 is pressed to drive the limit rod 12 to move toward the middle inside the square groove 10, so that the limit rod 12 no longer plays a fixed limiting role on the shell 1, and then the top cover 8 is taken out from the insertion groove 7, and the damaged electronic components inside the power adapter are replaced or repaired, avoiding the replacement of the entire power adapter and reducing the cost consumption. When the output end of the power adapter is damaged, the staff rotates the fixing bolt 19 to disassemble it, so that the mounting plate 18 is taken out from the fixing groove 17, making it more convenient for the staff to detect and repair the output end of the power adapter, further improving the maintenance efficiency of the power adapter.

[0025] Example 2: Figure 2-Figure 4 As shown, a sealing ring 5 is provided on the top of the shell 1, a dust ring 6 is provided on the top of the shell 1, an input interface 13 is provided on one side of the outer wall of the shell 1, a mounting block 14 is fixedly installed on one side of the outer wall of the shell 1, a protective plate 15 is movably inserted on the inner surface wall of the mounting block 14, a return spring 16 is provided between the inner surface walls of the mounting block 14 and the protective plate 15, a plurality of output interfaces 20 are provided on one side of the outer wall of the mounting plate 18, and each output interface 20 is provided with a mounting block 14, a protective plate 15 and a return spring 16 at a corresponding position of the mounting plate 18.

[0026] The effect achieved by the entire embodiment 2 is that when the power adapter is not in use, the protective plate 15 can be rotated around the circular groove opened on the outer wall of the mounting block 14 under the action of the reset spring 16, so that the protruding part of the protective plate 15 is embedded in the input interface 13 and the output interface 20, thereby preventing external dust and impurities from entering the input interface 13 and the output interface 20, thereby protecting the interface and avoiding damage caused by dust and impurities. When the power adapter is in use, under the operation of the staff, the rotating protective plate 15 inserts the connector into the input interface 13 and the output interface 20, so that it is put into use. At the same time, under the action of the sealing ring 5 and the dustproof ring 6, external dust and impurities can be effectively prevented from entering the power adapter, thereby protecting the power adapter and extending its service life.

[0027] Working principle: During use, when the power adapter is needed to power the device, first, under the operation of the staff, the protective plate 15 is rotated to insert the connector into the input interface 13 and the corresponding output interface 20, so as to power the device. At the same time, under the action of the sealing ring 5 and the dustproof ring 6, external dust and impurities can be effectively prevented from entering the power adapter, thereby protecting the power adapter. When the power adapter is damaged during use, the connector is removed from the input interface 13 and the output interface 20. Then, under the operation of the staff, the limit spring 4 is pressed to drive the limit plate 3 to move to both sides inside the installation groove 2, so that the limit plate 3 is removed from the limit groove 9, so that it no longer plays a role in fixing the top cover 8. Then, under the operation of the staff, the compression spring 11 inside the square groove 10 is pressed to drive the limit rod 12 to move inside the square groove 10. The intermediate movement makes the limit rod 12 no longer play a role in fixing and limiting the shell 1, and then the top cover 8 is taken out from the insertion slot 7, and the damaged electronic components inside the power adapter are replaced or repaired. When it is found that the output interface 20 of the power adapter is damaged, the staff rotates the fixing bolts 19 to disassemble it, and takes out the mounting plate 18 from the fixing slot 17, so as to detect and repair or replace the output interface 20, thereby improving the maintenance efficiency of the power adapter. When the power adapter is not in use, the protective plate 15 can be rotated around the circular groove opened on the outer wall of the mounting block 14 under the action of the reset spring 16, so that the protruding part of the protective plate 15 is embedded in the input interface 13 and the output interface 20, thereby preventing external dust and impurities from entering the input interface 13 and the output interface 20, protecting the power adapter and extending its service life.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
