Description

Technical Field

[0001] This utility model relates to the field of filter housing technology, specifically a detachable filter housing. Background Technology

[0002] Filters are key components in electronic devices used to remove noise, interference, or other unwanted frequency components from signals. A filter typically consists of internal circuitry and a housing. The housing not only protects the internal circuitry from external environmental influences but also provides electromagnetic shielding to prevent external electromagnetic interference from affecting the filter's performance.

[0003] Traditional filters are mostly designed as a single unit, requiring the entire device to be disassembled for replacement and cleaning. This is not only time-consuming and labor-intensive, but also significantly increases maintenance difficulty and time costs in confined spaces or high-frequency applications. Furthermore, the installation and removal of traditional filters typically require specialized tools and involve cumbersome procedures, further increasing operational difficulty and risk.

[0004] Therefore, this utility model provides a detachable filter housing. Utility Model Content

[0011] Preferably, a support plate is slidably provided in the docking groove, and a return spring is fixedly connected between the support plate and the inner wall of the docking groove. The number of return springs is multiple, and the multiple return springs are evenly distributed in the docking groove.

[0012] Beneficial effects

[0013] This invention provides a detachable filter housing. Compared with the prior art, it has the following advantages:

[0014] Beneficial effects:

[0015] (1) The detachable filter housing, through the design of the ring plate and the limiting plate, allows the filter to be quickly disassembled and replaced, reducing maintenance time and cost.

[0025] 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.

[0026] Example 1:

[0027] Please see Figure 1-5 A detachable filter housing includes a housing 1 and a cover plate 5, which are fixedly connected by bolts. A filter 2 is movably disposed inside the housing 1. An annular plate 3 is rotatably fitted on one side of the outer surface of the filter 2. Limiting plates 31 are symmetrically fixedly connected to both sides of the annular plate 3. Two first grooves 11 are symmetrically opened at the end of the housing 1 for the limiting plates 31 to engage. A second groove 12 is opened on one side of the first groove 11 for the limiting plates 31 to rotate and adjust. A mounting box 4 is fixedly connected to the outer surface of the housing 1 at the positions corresponding to the first groove 11 and the second groove 12. A limiting component is slidably disposed in the inner cavity of the mounting box 4.

[0028] Specifically, the limiting component includes a bracket 41 fixedly connected to the outside of the mounting box 4, a slide rod 42 slidably disposed inside the bracket 41, an insert plate 43 fixedly connected to one end of the slide rod 42, a spring 44 fixedly connected between the insert plate 43 and the bracket 41, and the spring 44 sleeved on the outside of the slide rod 42; a slot 32 is opened on the outside of the limiting plate 31, and the insert plate 43 is inserted into the slot 32; the end of the insert plate 43 is provided with a beveled surface, and a push plate 33 is fixedly connected to the surface of the limiting plate 31.

[0029] Furthermore, the housing 1 and cover plate 5 serve as the external protective layer of the entire device, with the filter 2 located inside the housing 1. The first groove 11 is used to engage the limiting plate 31, and the second groove 12 allows the limiting plate 31 to rotate and adjust. By inserting the filter 2 into the housing 1, the limiting plate 31 engages with the first groove 11 of the housing 1. The limiting plate 31 is rotated by the push plate 33. Both the limiting plate 31 and the insert plate 43 have rounded corners on both sides to allow for smooth outward sliding of the insert plate 43 during movement, reducing friction and jamming, and improving operational convenience and system reliability. Simultaneously, the slide rod 42 moves outward, and the spring 44 is in a stretched state. As the limiting plate 31 moves, when the insert plate 43 is aligned with the slot 32, the spring 44's elasticity causes the insert plate 43 to insert into the slot 32 of the limiting plate 31, ensuring the limiting plate 31 remains fixed, thereby achieving the installation of the filter 2. The end of the insert plate 43 is provided with a beveled surface to facilitate its smooth sliding when the limiting plate 31 enters, and to avoid jamming or damage.

[0030] When filter 2 needs to be replaced, pull the slide bar 42 outward to move the insert plate 43 out of the slot 32, releasing the lock on the limiting plate 31. Then, manually push the push plate 33 to move the limiting plate 31 out of the first groove 11. After that, remove filter 2, replace it, and reinstall it to ensure the system operates normally.

[0031] Example 2:

[0032] Please see Figure 2 , Figure 3 and Figure 6 This embodiment provides a technical solution based on embodiment one: a docking plate 21 is fixedly connected to the side of the filter 2 away from the annular plate 3, a docking groove 13 is opened at the bottom of the inner wall of the housing 1, the docking plate 21 is inserted into the docking groove 13, and a sealing gasket is provided between the contact surfaces of the docking plate 21 and the docking groove 13.

[0033] Specifically, a support plate 14 is slidably provided in the docking groove 13, and a return spring 15 is fixedly connected between the support plate 14 and the inner wall of the docking groove 13. There are multiple return springs 15, which are evenly distributed in the docking groove 13.

[0034] Furthermore, the mating plate 21 is inserted into the mating groove 13 at the bottom of the inner wall of the housing 1 to ensure the filter 2 is securely installed. A sealing gasket is placed between the contact surfaces of the mating plate 21 and the mating groove 13 to enhance the sealing performance. The mating plate 21 first contacts the support plate 14. During the installation of the filter 2, the return spring 15 is always in a compressed state. When the filter 2 is disassembled and replaced, the elastic force of the return spring 15 quickly ejects the mating plate 21 and the filter 2 from the housing 1, thereby increasing the disassembly speed of the filter 2 and further improving the disassembly efficiency of the filter 2.

[0035] Working Principle: During device use, the filter 2 is inserted into the housing 1, causing the docking plate 21 to be inserted into the docking groove 13. The docking plate 21 first contacts the support plate 14, at which point the return spring 15 is compressed, and the sealing gasket ensures a sealing effect. During this process, the limiting plate 31 is engaged in the first groove 11 of the housing 1. The limiting plate 31 is rotated by the push plate 33. Since the end of the insertion plate 43 is provided with a beveled surface, when the limiting plate 31 contacts the insertion plate 43, the slide rod 42 moves outward synchronously with the movement of the limiting plate 31, and the spring 44 is in a stretched state until the insertion plate 43 is aligned with the slot 32. Under the elastic action of the spring 44, the insertion plate 43 is inserted into the slot 32 of the limiting plate 31, ensuring that the limiting plate 31 is fixed in place, thereby realizing the installation of the filter 2. Finally, the cover plate 5 is installed on the housing 1 by bolts.
