DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following is combined with the attached Figures 1-5This application is described in further detail.

[0022] The present application embodiment discloses a 1U embedded switching power supply. Figures 1-5 A 1U embedded switching power supply comprises a chassis 1 and an embedded switching power supply body 2. The outer walls on both sides of the front of the chassis 1 are fixedly connected with fixed side panels 3. The outer walls of the two fixed side panels 3 are equipped with locking mechanisms for fixing the embedded switching power supply body 2. The outer walls on both sides of the front of the embedded switching power supply body 2 are fixedly connected with mounting plates 4. The back outer walls of the two mounting plates 4 are fixedly connected with buckles 5. The outer walls of the two fixed side panels 3 are provided with slots 14. The buckles 5 are adapted to be plugged into the slots 14.

[0023] The locking mechanism includes a plurality of connecting columns 7 fixedly connected to the outer walls on both sides of the chassis 1, a sliding rod 8 is fixedly connected to one end of the connecting column 7 away from the chassis 1, a movable plate 10 is slidably connected to the outer wall of each two adjacent sliding rods 8, a clamping block 11 is fixedly connected to the outer wall of the movable plate 10 facing the side of the chassis 1, a clamping slot 6 is provided on the outer wall of the buckle 5, and the clamping block 11 is adapted to be clamped in the clamping slot 6.

[0024] The locking mechanism also includes two connecting blocks 9 fixedly connected to the back outer wall of the fixed side plate 3. The end of the slide rod 8 away from the connecting column 7 is fixedly connected to the connecting block 9. The outer wall of the slide rod 8 located between the movable plate 10 and the connecting block 9 is sleeved with a spring 12.

[0025] A pull plate 13 is fixedly connected to the outer wall of the middle section of one side of the movable plate 10 away from the clamping block 11 , and the pull plate 13 is designed to be “L” shaped.

[0026] The end of the connecting column 7 away from the chassis 1 is in the same horizontal plane as the outer wall of the side of the buckle 5 away from the chassis 1. When the movable plate 10 slides on the outer wall of the slide rod 8, it is limited by the end of the connecting column 7. When the movable plate 10 is in contact with the end of the connecting column 7, the movable plate 10 is also in contact with the buckle 5, preventing the movable plate 10 from obstructing the insertion of the buckle 5 from the slot 14.

[0027] The ends of the buckle 5 and the block 11 are both designed to be inclined surfaces. The inclined surface of the end of the buckle 5 is arranged toward the movable plate 10 , and the inclined surface of the end of the block 11 is arranged toward the fixed side plate 3 .

[0028] The implementation principle of an embedded switching power supply in a 1U form in an embodiment of this application is as follows: When it is necessary to install the embedded switching power supply body 2, insert the embedded switching power supply body 2 into the chassis 1, and make the mounting plate 4 fit with the fixed side plate 3. At this time, the embedded switching power supply body 2 will completely enter the chassis 1. During this process, the locking mechanism will be automatically triggered to lock the position of the buckle 5 on the mounting plate 4, thus fixing the embedded switching power supply body 2. Specifically: When the mounting plate 4 moves and is inserted with the embedded switching power supply body 2 and fits with the fixed side plate 3, the buckle 5 on the mounting plate 4 is inserted into the slot 14 on the fixed side plate 3. And when the buckle 5 passes through the card slot 6, the end of it will squeeze the block 11. Through the inclined surface of the block 11 facing the end of the fixed side plate 3, the block 11 can be easily extruded outwards. The block 11 will push the movable plate 10 to slide outwards on the outer walls of the two sliding rods 8. The movable plate 10 will cooperate with the connecting block 9 to squeeze the spring 12, causing the spring 12 to deform and accumulate elastic force. When the mounting plate 4 fits with the fixed side plate 3, the buckle 5 completely passes through the card slot 6, and its position is fixed and cannot move forward any further. In this way, the card slot 6 on the outer wall of the buckle 5 will be aligned with the block 11, and the outer wall of the buckle 5 will no longer squeeze the block 11. The block 11 will no longer push the movable plate 10, and the movable plate 10 will reset under the elastic force of the two springs 12. Then the movable plate 10 drives the block 11 to be engaged with the card slot 6 to lock the buckle 5. At this time, the buckle 5 cannot be pulled outwards through the slot 14, so that the embedded switching power supply body 2 is firmly fixed in the chassis 1 to complete the installation;

[0029] When subsequent disassembly and maintenance are required, the operator can manually pull the pull plate 13 outwards. The pull plate 13 drives the movable plate 10 to slide outwards on the outer wall of the sliding rod 8. Then the sliding rod 8 pulls the block 11 to disengage from the card slot 6, unlocking the buckle 5. The buckle 5 can be pulled out through the slot 14, and thus the embedded switching power supply body 2 can be easily disassembled from the chassis 1. Compared with the prior art, there is no need to use screws for fixation, and the disassembly and assembly are quick and simple.
