[0022] A second mounting groove 14 is provided inside the mounting block 2 , and the second mounting groove 14 is located between the two first mounting grooves 5 . A slider 16 is slidably connected inside the second mounting groove 14 , and a card bead 17 is fixedly connected to an outer wall of one side of the slider 1 facing the inside of the fixing frame 1 .

[0023] The inner wall of the fixing frame 1 is provided with a plurality of adjustment grooves 13 , which are evenly distributed on the inner wall of the fixing frame 1 in a linear array, and the clamping beads 17 are adapted and clamped with the adjustment grooves 13 .

[0024] A pressing spring 15 is installed inside the second installation groove 14 . The pressing spring 15 is located between the slider 16 and the inner wall of the second installation groove 14 .

[0025] The disassembly and assembly mechanism also includes a plurality of avoidance grooves 9 opened inside the mounting block 2, and the plurality of avoidance grooves 9 are connected to the first mounting groove 5. The outer wall of the movable block 6 is fixedly connected with a connecting rod 10, and the connecting rod 10 is perpendicular to the clamping block 7, and the connecting rod 10 is slidably connected inside the avoidance groove 9.

[0026] The end of the connecting rod 10 away from the movable block 6 is fixedly connected to an extrusion rod 11, and the ends of multiple extrusion rods 11 away from the connecting rod 10 penetrate the mounting block 2, and the ends of every two adjacent extrusion rods 11 away from the connecting rod 10 are commonly fixedly connected to a connecting plate 12.

[0027] The implementation principle of a switching power supply that is easy to install in the embodiment of the present application is as follows: when in use, the fixing frame 1 is fixed inside the distribution box by welding. At this time, when installing the switching power supply body 3, it is only necessary to insert the mounting block 2 into the groove of the fixing frame 1. At this time, the disassembly mechanism is triggered, and the inner wall of the fixing frame 1 easily presses the clamping block 7 into the inside of the mounting block 2 through the inclined surfaces at the top of the two clamping blocks 7. At this time, the clamping block 7 squeezes the movable block 6 inwardly, and the movable block 6 slides inwardly in the inside of the slide groove 4 to squeeze the reset spring 8. The multiple reset springs 8 are deformed to generate elastic force. When the installation When the block 2 completely enters the interior of the fixing frame 1, the slide groove 4 corresponds to the block 7, and the inner wall of the fixing frame 1 no longer squeezes the block 7. At this time, the movable block 6 is reset under the elastic force of the reset spring 8, and the movable block 6 drives the block 7 to be clamped into the interior of the slide groove 4 to fix the switch power supply body 3. At this time, the switch power supply body 3 is clamped on the fixing frame 1, and when the installation block 2 is inside the fixing frame 1, the clamping bead 17 will be clamped with an adjustment groove 13 to limit the lateral position of the switch power supply body 3, which can prevent the switch power supply body 3 from sliding on the fixing frame 1;

[0028] When the switch power supply body 3 needs to be disassembled, only the two connecting plates 12 need to be pressed inwards, and the connecting plates 12 squeeze the multiple squeezing rods 11 inwards, so that the squeezing rods 11 drive the multiple connecting rods 10 to slide inwards inside the avoidance groove 9, and the movable block 6 slides into the first installation groove 5 under the drive of the avoidance groove 9, so as to drive the clamping block 7 to disengage from the sliding groove 4, and disassemble the switch power supply body 3. When the connecting plates 12 are released, the movable block 6 drives the clamping block 7 to reset again under the elastic force of the reset spring 8, so as to facilitate the next installation operation;

[0029] When it is necessary to adjust the spacing between multiple switch power supply bodies 3 in the fixing frame 1, the switch power supply bodies 3 are pushed hard to drive the mounting block 2 to slide inside the fixing frame 1, so that the clamping bead 17 is disengaged from the adjustment groove 13. During this process, the clamping bead 17 presses the slider 16 inward, so that the slider 16 slides into the second mounting groove 14 to squeeze the squeezing spring 15. The squeezing spring 15 deforms to generate elastic force. After the position is adjusted appropriately, the clamping bead 17 is re-engaged with an adjustment groove 13 under the elastic force of the squeezing spring 15, and the switch power supply bodies 3 are limited, thereby facilitating the position adjustment of multiple switch power supply bodies 3.
