[0040] A mounting groove 23 is provided in the middle of the rear end inner wall of the protective shell 1, and a mounting plate 17 is fixedly connected to the middle of the rear end outer wall of the switching power supply body 16. A No. 2 slide groove 18 is respectively provided on the upper and lower parts of both sides of the front end outer wall of the mounting plate 17. The top surface and the bottom surface of the adjacent side of the No. 2 slide groove 18 are respectively fixedly connected with a telescopic rod 19, and the telescopic ends of the telescopic rod 19 are respectively fixedly connected with a connecting block 20.

[0042] The second return springs 22 are respectively mounted on the outside of the telescopic rod 19;

[0043] The second return spring 22 applies a load to the connecting block 20 , thereby facilitating a tight connection between the fixing pin 21 and the fixing hole 24 , thereby preventing the mounting plate 17 from being separated from the mounting slot 23 .

[0044] The bottom and top surfaces of the mounting groove 23 are each provided with a fixing hole 24. The side of the fixing pin 21 away from the center of the mounting plate 17 passes through the mounting plate 17 and is connected to the fixing hole 24.

[0045] By using the mounting plate 17 in conjunction with the mounting groove 23 , the switching power supply body 16 can be conveniently mounted inside the protective housing 1 .

[0046] The No. 1 return springs 14 are respectively sleeved on the outside of the positioning pins 11, and the mounting plate 17 is connected to the mounting groove 23 by snapping;

[0047] The load is applied to the limiting ring 10 by the No. 1 return spring 14 , thereby tightly connecting the positioning pin 11 with the positioning hole 8 .

[0048] The side of the positioning pin 11 away from the center of the protective shell 1 sequentially passes through the No. 1 slide groove 9 to the outside of the protective shell 1 and is fixedly connected to the limit block 12.

[0049] The staff uses the pull ring 13 to facilitate the movement of the positioning pin 11 so that the limiting ring 10 compresses the No. 1 return spring 14, thereby disengaging the positioning pin 11 from the positioning hole 8, allowing the sealing plate 5 to slide inside the limiting groove 4.

[0050] The positioning pins 11 on one side close to the center of the protective shell 1 sequentially pass through the No. 1 slide groove 9 to the interior of the limiting groove 4 and are connected with the positioning hole 8 by snapping;

[0051] The positioning pin 11 cooperates with the positioning hole 8 to facilitate fixing the position of the sealing plate 5 inside the limiting groove 4.

[0052] A buckle groove 6 is provided at the upper end of the front outer wall of the sealing plate 5, and a wiring groove 15 is provided at the middle of the inner bottom surface of the protective shell 1;

[0053] The buckle groove 6 facilitates the staff to pull the sealing plate 5 , and the wiring groove 15 facilitates the staff to pass the wires connected to the switching power supply body 16 through the protective shell 1 .

[0056] Working principle: When using this autonomous controllable high-reliability switching power supply, first, the mounting plate 17 is clamped together with the switching power supply body 16 to the inside of the mounting groove 23. Secondly, the No. 2 return spring 22 is used to apply a load to the connecting block 20, so that the fixing pin 21 is conveniently clamped to the inside of the fixing hole 24, thereby preventing the mounting plate 17 from disengaging from the mounting groove 23. Thirdly, the pull ring 13 is used to facilitate the movement of the positioning pin 11, so that the limiting ring 10 compresses the No. 1 return spring 14, so that the positioning pin 11 is disengaged from the positioning hole 8, so that the sealing plate 5 can slide inside the limiting groove 4. Then, after the lower end of the sealing plate 5 is in contact with the bottom surface of the protective shell 1, finally, the No. 1 return spring 14 is used to apply a load to the limiting ring 10, so that the positioning pin 11 is clamped to the inside of the positioning hole 8, thereby fixing the sealing plate 5 to the inside of the limiting groove 4.
