Technical Field
[0001] This utility model relates to the field of filter element installation technology, and more specifically, to a quick-release filter element installation structure. Background Technology
[0002] Car manufacturing workshops generate significant amounts of dust, fumes, and other pollutants during production. To ensure air quality and worker health, highly efficient air purification equipment is essential. As a core component of air purification equipment, the ease of replacement of the filter directly impacts maintenance efficiency and operating costs.
[0003] Existing filter element installation structures typically involve the engagement of a snap-fit connector on the filter element with a slot on the filter itself, enabling quick installation and removal. Filter elements used in automotive production workshops require consistent filtration performance and regular replacement. However, frequent installation and removal can cause wear and tear on the snap-fit and slot connections, leading to loosening and affecting the stability of the filter element installation. Therefore, an installation structure that maintains the filter element's stable position under repeated installation and removal is crucial. To address this, we propose a quick-release filter element installation structure. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a quick-release filter element installation structure to solve the technical problem that the contact parts of the buckle and the slot will gradually wear due to frequent installation and disassembly operations, resulting in loosening of the connection and affecting the stability of filter element installation.
[0005] To solve the above technical problems, this utility model provides the following technical solution: a quick-release filter element installation structure, including a filter element body and an installation plate, wherein a connecting ring is fixedly provided on the top of the filter element body, and the inner side of the connecting ring is fitted and connected to the outer side of the bottom of the installation plate, and a locking member that is inserted into the connecting ring is fixedly provided on the bottom of the installation plate;
[0006] An annular groove is provided on the outer wall of the connecting ring, and a guide ring is movably installed inside the annular groove.
[0007] The locking component has an outwardly protruding locking block installed inside, and the top of the locking block is in contact with the top side of the annular slot.
[0008] The annular surface of the guide ring is configured as a downwardly inclined pushing slope, and the lower side of the locking block is configured as an upwardly inclined guiding slope, with the guiding slope fitting against the top side of the guide ring.
[0009] This invention enables the installation of the filter element body and the mounting plate through the combination of the connecting ring and the mounting plate. The locking block, supported by the locking component, can automatically retract under the pressure of the connecting ring. With the limiting of the guide ring, the side end of the locking block can be locked into the inner side of the annular groove, thus fixing the installation position of the filter element body. When the connecting ring continues to move upward, it can press the locking block into the position where it engages with the guide ring. By pulling it down, the locking block can drive the guide ring to move upward synchronously, thereby separating the locking block from the annular groove. This structure allows for quick assembly and disassembly, reduces wear, and improves the stability of repeated installation.
[0010] Preferably, the top of the guide ring is provided with a number of positioning teeth at equal intervals, and the guide slope of the locking block is provided with a number of positioning grooves that engage with the positioning teeth.
[0011] Preferably, the locking component includes a housing, a fixing plate is fitted inside the housing, and a plurality of springs are fixedly provided on the other side of the fixing plate. A connecting plate that is engaged with the locking block is fixedly connected between the plurality of springs.
[0012] Preferably, the outer shell is provided with a threaded hole in the middle of the side wall of the fixing plate, and the threaded hole is internally threaded with an adjusting bolt whose side end abuts against the side of the fixing plate.
[0013] Preferably, the top of the locking block is provided with an upwardly inclined extrusion surface, and the angle of inclination of the extrusion surface is the same as the angle of inclination of the pushing slope.
[0014] Preferably, the top of the positioning tooth is V-shaped, and the bottom opening size of the positioning groove is larger than the top size of the positioning tooth.
[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] 1. This utility model enables the installation of the filter element body and the mounting plate through the combination of the connecting ring and the mounting plate. The locking block, supported by the locking component, can automatically retract under the pressure of the connecting ring. With the limiting of the guide ring, the side end of the locking block can be locked into the inner side of the annular groove, thereby fixing the installation position of the filter element body. When the connecting ring continues to move upward, it can press the locking block to the position where it engages with the guide ring. By pulling it down, the locking block can drive the guide ring to move upward synchronously, thereby separating the locking block from the annular groove. This structure can achieve quick disassembly and assembly, reduce wear, and improve the stability of repeated installation.
[0017] 2. This utility model also uses the cooperation of positioning groove and positioning teeth to fix the installation position of the filter element body, further improving the stability of the installation position of the filter element body and the mounting plate. At the same time, such a structure does not require positioning installation, saving the positioning steps in the installation process and speeding up the installation.
[0018] 3. In this utility model, the spring can adjust its expansion and contraction strength by adjusting the bolt and the fixing plate. This allows for manual adjustment when elastic fatigue occurs during repeated expansion and contraction, eliminating the need for disassembly and replacement. It maintains good elastic support, enhances the stability of the locking block support, prevents loosening, and improves the durability of the structure. Attached Figure Description

[0026] like Figures 1 to 6 As shown, this utility model relates to a quick-release filter element installation structure, which includes a filter element body 1 and an installation plate 2. A connecting ring 3 is fixedly provided on the top of the filter element body 1, and the inner side of the connecting ring 3 is in close contact with the outer side of the bottom of the installation plate 2. A locking member 5 that is inserted into the connecting ring 3 is fixedly provided on the bottom of the installation plate 2. The filter element body 1 can be fixedly installed on the bottom of the installation plate 2 by the combination of the connecting ring 3 and the locking member 5, so as to achieve the assembly effect.
[0027] An annular groove 301 is provided on the outer wall of the connecting ring 3. A guide ring 4 is movably installed inside the annular groove 301. A locking block 6 protruding outward is elastically installed inside the locking component 5. The top of the locking block 6 is in contact with the top side of the annular groove 301. The annular surface of the guide ring 4 is set as a downwardly inclined pushing slope 401. The lower side of the locking block 6 is set as an upwardly inclined guiding slope 601. The guiding slope 601 is in contact with the top side of the guide ring 4. The design of the annular groove 301 makes it easy to insert the side end of the locking block 6, thereby achieving the effect of limiting connection. The design of the guiding slope 601 makes it easy for the connecting ring 3 to automatically shift when it moves upward due to compression. The design of the pushing slope 401 makes it easy to squeeze the locking block 6 to shift after the guide ring 4 moves into place when it comes into contact with the locking block 6, which facilitates separation operation.
[0028] In the embodiments of this utility model, a plurality of positioning teeth 402 are equidistantly arranged on the top of the guide ring 4, and a plurality of positioning grooves 602 that engage with the positioning teeth 402 are opened upward on the guide inclined surface 601 of the locking block 6. The engagement of the positioning grooves 602 and the positioning teeth 402 can fix the installation position of the connecting ring 3. This structure does not require pre-positioning of the installation position of the connecting ring 3, making operation convenient.
[0029] In an embodiment of this utility model, the locking component 5 includes a housing 501, a fixing plate 502 is fitted inside the housing 501, and a plurality of springs 503 are fixedly provided on the other side of the fixing plate 502. A connecting plate 504 that is combined with the locking block 6 is fixedly connected between the plurality of springs 503. The locking block 6 can be easily moved by the cooperation of the fixing plate 502, the springs 503 and the connecting plate 504, so as to achieve the effect of automatic displacement and reset.
[0030] In an embodiment of this utility model, a threaded hole 505 is provided in the middle of the side wall of the outer shell 501 that is attached to the fixing plate 502. An adjusting bolt 7 with its side end abutting against the side of the fixing plate 502 is connected to the threaded hole 505. The position of the fixing plate 502 can be easily adjusted by the cooperation of the threaded hole 505 and the adjusting bolt 7, so that the spring 503 can be compressed and contracted. This can improve the elastic support effect of the spring 503, reduce the problem of elastic fatigue caused by repeated expansion and contraction, which leads to a decrease in the support effect, and improve durability.
[0031] In an embodiment of this utility model, the top of the locking block 6 is provided with an upwardly inclined pressing surface 603, and the angle of inclination of the pressing surface 603 is the same as the angle of inclination of the pushing inclined surface 401; the design of the pressing surface 603 can further improve the fit with the pushing inclined surface 401, making it easier to push the guide ring 4 upward to complete the separation operation.
[0032] In the embodiments of this utility model, the top end of the positioning tooth 402 is V-shaped, and the bottom opening size of the positioning groove 602 is larger than the top end size of the positioning tooth 402; such a fit facilitates snap-fit connection and makes quick docking operation convenient.
[0033] Working Principle: This embodiment provides a quick-release filter element installation structure. During installation, firstly, the connecting ring 3 at the top of the filter element body 1 is aligned with the outer wall extending from the bottom of the mounting plate 2. Then, by pressing upwards, the connecting ring 3 is moved upwards along the bottom of the mounting plate 2, causing it to squeeze the protruding locking block 6 into the locking member 5. When the side end of the locking block 6 reaches the position of the annular locking groove 301, it can automatically pop out, thereby achieving the insertion effect. This completes the installation operation of the filter element body 1. At the same time, during the insertion process, the positioning teeth 402 can be engaged into the interior of the positioning groove 602, which can further position the filter element body 1 and maintain its positional stability. When removing the filter element body 1, the connecting ring 3 can be... The continuous upward movement causes the locking block 6 to be compressed and contracted by the guide ring 4, which moves the side end of the locking block 6 to the position of the pushing inclined surface 401. Then, by pulling down, the locking block 6 drives the guide ring 4 to move upward synchronously. When the top of the guide ring 4 moves to the top position of the annular groove 301, the side end of the locking block 6 can be squeezed and shifted under pressure, allowing it to move from the position of the guide ring 4 to the outer surface of the connecting ring 3. Then, by pulling down the filter body 1, the locking block 6 slides out from the outside of the connecting ring 3, achieving the effect of releasing the limit. This structure allows for quick assembly and disassembly, and at the same time, this structure can reduce wear during repeated assembly and disassembly, maintaining good limit stability.

Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
