[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-4 This utility model provides a technical solution: a quick-release dustproof inverter housing structure, including a housing 1 and a dustproof net 2, and further including: a plurality of snap-fit components one, each snap-fit component one including a circular shell 3 fixedly installed on the housing 1 and a plurality of arc-shaped plates 5 rotatably installed on the circular shell 3, wherein a return spring 7 is installed between the arc-shaped plates 5 and the circular shell 3; and a plurality of snap-fit components two, each snap-fit component two including a plug rod 4 fixedly installed on the dustproof net 2 and a circular plate 6 fixedly installed on the plug rod 4, wherein the arc-shaped plates 5 cooperate with the circular plates 6 to realize the disassembly and installation of the dustproof net 2.
[0022] In use, this solution restricts the arc plate 5 to rotate inwards only. After the first and second buckle components are inserted, the rod 4 and the round plate 6 cannot be removed due to the restriction of the arc plate 5, meaning the dust net 2 cannot be removed, thus achieving the disassembly action. During disassembly, pushing the arc plate 5 inwards to rotate it allows the dust net 2 to be quickly disassembled through the cooperation of the first and second buckle components, facilitating cleaning and making it convenient to use.
[0023] Please see Figures 3-4 The buckle assembly also includes a ring 8 rotatably mounted on the circular shell 3, and the ring 8 is provided with a groove 9 for the arc plate 5 to rotate.
[0024] In use, this solution uses a rotating ring 8 to drive the groove 9 to rotate synchronously, thereby restricting the rotation of the arc plate 5.
[0025] Please see Figures 3-4 The first buckle assembly also includes a guide rod 12 fixedly installed at the center of the circular shell 3, and the guide rod 12 is slidably connected to the insertion rod 4.
[0026] When using this solution, guide rod 12 is installed to prevent the insertion rod 4 and dustproof net 2 from shaking.
[0027] Please see Figures 3-4 The second buckle assembly contains two circular plates 6, and the first buckle assembly contains two sets of corresponding arc-shaped plates 5, a return spring 7, and a circular ring 8.
[0028] Using this solution, setting up two sets will improve the fixation effect.
[0029] Please see Figures 3-4 The ring 8 has a groove 11, and a fixing rod 10 is installed between the two rings 8. The fixing rod 10 slides in the groove 11.
[0030] Please see Figures 1-2 An extrusion plate 13 is slidably mounted on the outer shell 1. The extrusion plate 13 is slidably connected to the circular shell 3. The outer dimensions of the extrusion plate 13 are the same as those of the dustproof net 2. A pressure spring 14 is installed between the extrusion plate 13 and the outer shell 1.
[0031] During use, this solution applies pressure to the dustproof net 2 by setting up the extrusion plate 13 and the pressure spring 14, so that the extrusion plate 13 and the dustproof net 2 are tightly attached to each other, thus preventing the problem of air carrying dust from entering through the gaps in the dustproof net 2.
[0032] In this invention, when a person skilled in the art uses the device, first rotate the ring 8 so that the arc plate 5 can only be recessed inward. During installation, insert the rod 4 into the inside of the circular shell 3, causing the circular plate 6 to move synchronously. During the movement, the circular plate 6 pushes the arc plate 5 to rotate inward, causing the return spring 7 to be compressed until the circular plate 6 passes through the arc plate 5. The arc plate 5 returns to its original position under the elastic force of the return spring 7. At this time, the dustproof net 2 slides outward under the action of the pressure spring 14 and the squeezing plate 13, causing the rod 4 and the first plate to move synchronously. Due to the restriction of the arc plate 5, the circular plate 6 cannot pass through, and at this time the circular plate 6 is in close contact with the arc plate 5, thus realizing the installation action. During disassembly, rotate the ring 8 so that the groove 9 rotates to the rotation trajectory of the arc plate 5. At this time, the arc plate 5 can rotate outward. At this time, pull the dustproof net 2 outward to remove the rod 4 and the circular plate 6 from the circular shell 3, thus realizing the disassembly action.
