[0033] In order to further understand the content of the utility model, the utility model will be described in detail in combination with the drawings.

[0034] Combination Figures 1-4 A single-standing low-frequency transformer includes an installation area 1. A connecting seat 2 is provided at the top of the installation area 1. A receiving plate 3 is slidably connected through the top of the connecting seat 2. A low-frequency transformer 18 is fixedly connected to the top of the receiving plate 3. An installation groove 8 is provided at the top of the installation area 1. A column 11 is fixedly connected to the middle of the installation area 1, located in the middle of the installation groove 8. A limiting member 10 is fixedly connected to the top of the column 11. The inclined surface at the top of the limiting member 10 pushes the limiting post 14 to both sides, allowing the installation seat 9 to be smoothly inserted. The flat surface at the bottom of the limiting member 10 prevents the limiting post 14 from moving. The mounting base 9 is limited in position. The bottom end of the column 11 is slidably connected to a sliding member 13. When disassembling, the limiting post 14 drives the sliding member 13 to move. The bottom of the connecting base 2 is fixedly connected to the mounting base 9, and the mounting base 9 is set in the middle of the mounting groove 8. The mounting base 9 is inserted into the mounting groove 8. The bottom sides of the inner wall of the mounting base 9 are slidably connected to the limiting post 14. The middle of the mounting base 9 is provided with a spring 15, and one end of the spring 15 is fixedly connected to the outer wall of the limiting post 14. The spring 15 pops out the limiting post 14 to limit the position. The top of the receiving plate 3 is provided with a noise reduction component.

[0035] Combination Figure 1 The noise reduction component includes a shielding shell 5, which is fixedly connected to the top of the receiving plate 3. A sound-absorbing cotton 19 is slidably connected through the middle of the shielding shell 5. The sound-absorbing cotton 19 can absorb sound and reduce sound reflection, thereby reducing the noise generated by the vibration of the low-frequency transformer during operation. Different sound-absorbing cotton 19 can be placed in the shielding shell 5 to adapt to the noise emitted by different low-voltage frequency converters 18.

[0036] Combination Figures 1-5 The outer wall of the shielding shell 5 is fixedly connected with evenly distributed heat sinks 4, which dissipate the heat generated by the low-voltage frequency converter 18 during operation. A ring 12 is fixedly connected to the top of the sliding member 13, and the radius of the ring 12 is smaller than the bottom radius of the limiting member 10. The ring 12 facilitates the pushing of the limiting post 14. A guide block 16 is fixedly connected to the bottom of the limiting post 14, and the guide block 16 cooperates with the ring 12. The guide block 16 facilitates the pushing of the limiting post 14 and makes disassembly convenient. The connecting seat 2 has evenly distributed shock-absorbing resistors running through its middle. The damping 17 is fixedly connected to the bottom of the receiving plate 3 at its top. The damping 17 absorbs the vibration of the low frequency transformer 18 during operation, thereby reducing noise. The bottom of the connecting seat 2 is fixedly connected with evenly distributed positioning columns 7, which penetrate through and slide through the top of the installation area 1. The positioning columns 7 prevent the vibration of the low frequency transformer 18 from causing the connecting seat 2 to rotate. The bottom right side of the shielding shell 5 is connected to a wire conduit 6, through which wires are placed into the shielding shell 5 and connected to the low frequency transformer 18.

[0037] Working principle: The mounting base 9 under the connecting base 2 is inserted into the pre-cut mounting slot 8 in the mounting area 1. At this time, the inclined surface at the top of the limiting member 10 pushes the limiting post 14 to both sides, so that the mounting base 9 can be inserted smoothly. The flat surface at the bottom of the limiting member 10 cannot move the limiting post 14, so that the mounting base 9 can be limited and the installation of the low frequency transformer 18 is completed. When the low frequency transformer 18 is working, the low frequency transformer 18 will vibrate, thereby generating noise. The sound-absorbing cotton 19 that runs through and is fixedly connected in the middle of the shielding shell 5 will reduce the noise. The sound-absorbing cotton 19 can absorb sound and reduce sound reflection, thereby reducing the noise generated when the low frequency transformer 18 is working.
