Detailed Implementation

[0026] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] See attached document Figure 1 - Appendix Figure 6This utility model provides a fixing device for a power supply, including a chassis body 1. A power supply fixing base 2 is fixedly installed inside the chassis body 1. Two through slots 3 are formed at the bottom of the power supply fixing base 2. A snap-on switch 4 is inserted into one side of the power supply fixing base 2. A limit ring 5 is fixedly installed outside the snap-on switch 4. A hollow rod 6 is fixedly installed at one end of the snap-on switch 4. A fixing rod 7 is inserted inside one end of the hollow rod 6. A spring 8 is sleeved on the outside of the hollow rod 6. A connecting sleeve 9 is fixedly sleeved on the outside of the hollow rod 6. Fixing units are provided on both sides of the connecting sleeve 9. Each fixing unit includes a rotating shaft 10. A connecting plate 11 is fixedly inserted into the outside of the rotating shaft 10. A rotating shaft 12 is fixedly inserted into one end of the connecting plate 11. A connecting block 13 is sleeved on the outside of the rotating shaft 12. A clamping plate 14 is fixedly installed on one side of the connecting block 13. A limiting strip 15 is fixedly installed on one side of the clamping plate 14. A power supply cover 16 is provided between the two clamping plates 14. Limiting grooves 17 are opened on both sides of the power supply cover 16. Multiple buckles 18 are fixedly installed at the bottom of the power supply cover 16. A power supply bottom cover 19 is provided at the bottom of the power supply cover 16. Multiple buckle grooves 20 are opened on the outside of the power supply bottom cover 19.

[0028] In this embodiment, in order to facilitate the disassembly of the power supply casing, pressing the latch switch 4 causes the latch switch 4 to move into the power supply mounting base 2. When the latch switch 4 moves, it drives the hollow rod 6 to move along the fixing rod 7 and causes the spring 8 to contract. At the same time, when the hollow rod 6 moves, it drives the connecting sleeve 9 to move. The movement of the connecting sleeve 9, through the cooperation of the two rotating shafts 10, the connecting plate 11, and the rotating shaft 12, causes the two connecting blocks 13 to move to the sides. The movement of the connecting blocks 13 drives the clamping plate 14 to move. The movement of the clamping plate 14 causes the limiting strip 15 to be pulled out from the limiting groove 17, thereby releasing the fixation of the power supply top cover 16, making it easier to remove the power supply top cover 16 and the power supply bottom cover 19, thus facilitating the removal of the power supply.

[0029] To achieve the automatic reset of the pressure switch 4, the device employs the following technical solution: the pressure switch 4 penetrates one side wall of the power supply mounting base 2 and is slidably connected to it; the hollow rod 6 is sleeved outside the fixed rod 7 and is slidably connected to it; one end of the fixed rod 7 is fixedly connected to one side wall of the power supply mounting base 2; one end of the spring 8 is sleeved outside the hollow rod 6 and is fixedly connected to it; the other end of the spring 8 is fixedly connected to one side wall of the power supply mounting base 2. When the pressure switch 4 is pressed, it moves into the power supply mounting base 2. As the pressure switch 4 moves, it drives the hollow rod 6 to move along the fixed rod 7 and causes the spring 8 to contract. When the pressure switch 4 is released, the elastic force of the spring 8 causes the hollow rod 6 to reset, thereby resetting the pressure switch 4. At the same time, the limit ring 5 prevents the pressure switch 4 from overextending.

[0030] To achieve synchronous movement of the two clamping plates 14, the device employs the following technical solution: the top of the rotating shaft 10 passes through the connecting sleeve 9 and is connected to the connecting sleeve 9 via a bearing; the bottom of the rotating shaft 2 12 passes through the connecting block 2 13 and is connected to the connecting block 2 13 via a bearing; the connecting block 2 13 is located at the bottom of the inner cavity of the power supply mounting base 2 and is slidably connected to the bottom of the inner cavity of the power supply mounting base 2; the clamping plate 14 has a through groove 3 and is slidably connected to the through groove 3; the limiting strip 15 extends into the limiting groove 17 and is slidably connected to the limiting groove 17; and the clamping plate 14 is secured. One end of buckle 18 extends into the buckle groove 20 and engages with it. The movement of connecting sleeve 9 is achieved by the cooperation of two rotating shafts 10, connecting plate 11, and rotating shaft 12 on both sides, which causes the two connecting blocks 13 on both sides to move to the sides. The movement of connecting block 13 drives the clamping plate 14 to move, and the movement of clamping plate 14 drives the limit strip 15 to move, thereby achieving the purpose of controlling whether the limit strip 15 is inserted into the limit groove 17, thus facilitating the control of whether the power supply cover 16 of the chassis is in a restricted state, and facilitating the control of whether the power supply cover 16 of the chassis can be disassembled.

[0031] The usage process of this utility model is as follows: When using this utility model, if it is necessary to disassemble the power supply chassis, press the latch switch 4. The latch switch 4 moves into the power supply chassis mounting base 2. When the latch switch 4 moves, it drives the hollow rod 6 to move along the fixing rod 7 and causes the spring 8 to contract. At the same time, when the hollow rod 6 moves, it drives the connecting sleeve 9 to move. The movement of the connecting sleeve 9, through the cooperation of the two rotating shafts 10, connecting plate 11, and rotating shaft 12, causes the two connecting blocks 13 on both sides to move to the sides. The movement of the connecting blocks 13 drives the clamping plate 14 to move. The movement of the clamping plate 14 leads to... The movable limit strip 15 is pulled out from inside the limit groove 17, thereby releasing the fixation on the power supply top cover 16, making it easier to remove the power supply top cover 16 and the power supply bottom cover 19, thus facilitating the removal of the power supply. Similarly, the above operation is performed simultaneously during installation. Then, the power supply top cover 16 is placed between the two limit strips 15, and then the snap switch 4 is released. The retracted spring 8 causes the hollow rod 6 to return to its original position, thereby causing the limit strip 15 to automatically insert into the limit groove 17, thus quickly fixing the power supply top cover 16, achieving the purpose of quickly installing the power supply.
