[0002] A DC power filter is a device used to minimize the pulsation or fluctuation components in a DC power supply. This filter is usually used in electronic equipment or power systems to ensure the stability and reliability of the DC power supply. DC power supplies usually contain some AC components or fluctuations, which may come from the design of the power supply itself or the influence of the external environment. The main function of a DC power filter is to eliminate or reduce the AC components in the DC power supply, which may be caused by fluctuations introduced by the rectification process or other reasons. Common DC power filters include capacitor filters and inductor filters.

[0003] When installing traditional filter housings, they are often assembled with small parts such as bolts and nuts. Bolts and nuts provide strong fixing force to ensure that the various parts of the filter housing can be tightly connected together, making the entire filter structure stable and not prone to loosening or deformation. The assembly of small parts can help ensure the sealing of the filter housing. By properly installing bolts, nuts and washers, external impurities and dust can be effectively prevented from entering the filter, protecting the internal components of the filter from the influence of the external environment.

[0004] However, although the traditional filter housing installation method can achieve the effect of firmly fixing the housing, it does not take into account the problem that fixing with small parts such as bolts and nuts requires the use of professional installation tools during installation, which is more troublesome. In addition, the threaded and bolted fixing method is prone to rust at the connection parts after long-term use, making it inconvenient to disassemble later. Utility Model Content

[0007] Furthermore, the positioning assembly includes a positioning column, the lower surface of the positioning column is fixedly connected to the upper surface of the base plate, and the side wall of the positioning column is slidably connected to the inside of the shell.

[0008] Furthermore, a fixing ring is fixedly connected to the side wall of the rotating column, and an extension plate is fixedly connected to the side wall of the fixing ring.

[0009] Furthermore, a latch is slidably connected inside the extension plate, and a side wall of the latch is slidably connected inside the side plate.

[0010] Furthermore, the side wall of the latch is fixedly connected to a limit plate, and a spring is sleeved on the side wall of the latch.

[0011] Furthermore, one end of the spring is fixedly connected to the upper surface of the limiting plate, and the other end of the spring is fixedly connected to the lower surface of the extension plate.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 2 - Figure 4The utility model provides an embodiment: a DC power filter that is easy to install, including a bottom plate 1, a shell 2 is arranged on the top of the bottom plate 1, a positioning assembly is arranged on the upper surface of the bottom plate 1, a clamping ring 4 is fixedly connected inside the shell 2, a side plate 5 is fixedly connected to the side wall of the shell 2, a limiting groove 6 is provided inside the clamping ring 4, a connecting ring 7 is fixedly connected inside the side plate 5, a limiting block 8 is fixedly connected to the side wall of the connecting ring 7, the side wall of the limiting block 8 is slidably connected inside the limiting groove 6, a fixing seat 9 is fixedly connected inside the connecting ring 7, and the fixing seat 9 is inside A slide plate 10 is fixedly connected, a block 11 is slidably connected inside the slide plate 10, and the side wall of the block 11 is slidably connected inside the clamping ring 4. A rotating plate 12 is rotatably connected inside the fixed seat 9, a groove 13 is opened inside the rotating plate 12, and the side wall of the block 11 is slidably connected inside the groove 13. A rotating column 14 is rotatably connected inside the side plate 5, and the lower surface of the rotating column 14 is fixedly connected to the upper surface of the rotating plate 12. The positioning assembly includes a positioning column 3, the lower surface of the positioning column 3 is fixedly connected to the upper surface of the base plate 1, and the side wall of the positioning column 3 is slidably connected inside the shell 2.

[0024] During the installation and fixing process of the filter housing, when the housing 2 is connected to the bottom plate 1, the positioning column 3 will be inserted into the inside of the housing 2 to play a preliminary positioning role. After the housing 2 is initially connected to the bottom plate 1, the connecting ring 7 will be inserted into the inside of the clamping ring 4. After the connecting ring 7 is inserted into the clamping ring 4, the limiting block 8 will smoothly slide into the inside of the limiting groove 6, thereby further limiting the relative movement between the housing 2 and the bottom plate 1. Finally, the rotating column 14 is rotated to drive the rotating plate 12 to rotate. Under the restriction of the groove 13, the rotation of the rotating plate 12 will cause the clamping block 11 to slide inside the slide plate 10. As the rotating plate 12 continues to rotate, one side of the clamping block 11 will gradually slide into the inside of the clamping ring 4, thereby fixing the bottom plate 1 and the housing 2 again.

[0025] Reference Figure 1 - Figure 3 The side wall of the rotating column 14 is fixedly connected with a fixing ring 15, and the side wall of the fixing ring 15 is fixedly connected with an extension plate 16. The side wall of the rotating column 14 is fixedly connected with a fixing ring 15, and the side wall of the fixing ring 15 is fixedly connected with an extension plate 16. A latch 17 is slidably connected inside the extension plate 16, and the side wall of the latch 17 is slidably connected inside the side plate 5. The side wall of the latch 17 is fixedly connected with a limiting plate 18, and the side wall of the latch 17 is sleeved with a spring 19, one end of the spring 19 is fixedly connected to the upper surface of the limiting plate 18, and the other end of the spring 19 is fixedly connected to the lower surface of the extension plate 16, and a pull ring 20 is fixedly connected to the upper surface of the latch 17.

[0026] During the installation and fixing process of the filter housing, the pin 17 is pulled out from the inside of the side plate 5 through the pull ring 20. In this step, the movement of the pin 17 will squeeze the spring 19, causing it to shrink under pressure, so that the rotating column 14 loses its original restriction and can rotate freely. At this time, the filter housing 2 is placed in an appropriate position and the rotating column 14 is rotated to complete the installation work. When the filter housing is installed, the pull ring 20 is released. At this time, the spring 19 loses its previous pressure and begins to reset, pushing the pin 17 to reinsert into the inside of the side plate 5. The insertion of the pin 17 not only fixes the rotating column 14, but also ensures the stability of the filter housing during use.

[0027] Working principle: When installing and fixing the filter housing, the housing 2 is connected to the base plate 1, and the positioning column 3 on the upper surface of the base plate 1 is inserted into the interior of the housing 2 for positioning. At this time, the connecting ring 7 is just inserted into the interior of the clamping ring 4, and the limit block 8 slides into the interior of the limit groove 6. At this time, the latch 17 is pulled out from the interior of the side plate 5 through the pull ring 20, so that the spring 19 is squeezed and contracted. At this time, the rotating plate 12 is driven to rotate by rotating the rotating column 14. Under the restriction of the groove 13, the rotation of the rotating plate 12 will cause the block 11 to slide inside the slide plate 10, and one side of the block 11 will slide into the interior of the clamping ring 4, and the base plate 1 and the housing 2 are fixed again. After the installation is completed, the pull ring 20 is loosened by the ground. At this time, the spring 19 loses pressure and resets, thereby pushing the latch 17 to move, inserting it into the interior of the side plate 5 to fix the rotating column 14, thereby ensuring the stability of the housing connection during use.
