Description

Technical Field

[0001] This utility model relates to the field of filter equipment technology, specifically to a quick-install filter element. Background Technology

[0002] A filter is an indispensable device in a pipeline for transporting media. After the media to be processed passes through the filter, it is filtered by the filter element inside the filter to block the impurities it carries. The filter element is the core component of the filter. In order to ensure the normal flow of the media and effective filtration, the filter element needs to be disassembled and cleaned regularly.

[0003] Chinese patent application CN218011457U discloses a quick-release device for an oil filter element, including a quick-release base. A filter element is mounted on one side of the quick-release base. A connection hole is formed on the side wall of the quick-release base near the filter element. The end of the filter element near the quick-release base is connected through the connection hole. Connection grooves are formed on the inner walls of both ends of the connection hole near the filter element. Limiting blocks are fixedly connected to the outer walls of the filter element that match the positions of the two connection grooves. Limiting grooves are also formed on the inner walls of the connection hole near the two ends of the connection grooves. During use, a locking spring, in conjunction with the locking block, compresses the limiting blocks, thereby limiting the installation of the filter element. Disassembly is performed by simply rotating the filter element clockwise, improving the efficiency of oil filter element replacement, facilitating filter element replacement and cleaning, and enhancing the filtration effect of the oil filter.

[0004] The aforementioned technology achieves filter element installation by adding a limiting block to the side of the filter element, along with a quick-release base containing a connecting groove, limiting groove, locking block, and locking spring. While this enables quick installation and removal, gaps remain between the filter element and the quick-release base after installation, potentially leading to media leakage. Furthermore, when both the upper and lower ends of the filter element need to be fixed via connecting flanges, although the filter element can rotate between the two flanges, the fixed connecting flanges restrict its movement, preventing removal. In such cases, one connecting flange needs to be disassembled, which presents certain limitations and is not convenient. Therefore, this technology proposes a quick-install filter element. Utility Model Content

[0005] The purpose of this invention is to provide a quick-install filter element to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-install filter element, comprising an upper flange, a filter element body, and a lower flange. The upper flange is located above the lower flange. A stepped seat is fixed to the middle of the lower end of the upper flange. An upper limit ring is threadedly connected to the upper side of the filter element body, and a lower limit ring is threadedly connected to the lower side of the filter element body. The upper part of the filter element body is inserted into the stepped seat, and the upper limit ring contacts the side of the stepped seat. A hollow seat is fixed to the middle of the upper end of the lower flange. A connecting seat is movably connected within the hollow seat. The lower part of the filter element body is inserted into the connecting seat, and the lower limit ring engages with the connecting seat. A fixing ring is fitted and fixed to the side of the connecting seat. A telescopic rod is fixed to the lower end of the fixing ring. The telescopic rod is inserted into the hollow seat, and a spring is fixed to the bottom of the telescopic rod. The spring is fixed within the hollow seat.

[0007] As a further preferred embodiment of this technical solution, a first sealing ring is bonded and fixed inside the stepped seat, and the first sealing ring is in contact with the upper part of the filter element body.

[0008] As a further preferred embodiment of this technical solution, the inner walls of the upper limit ring and the lower limit ring are machined with internal threads, and the upper and lower parts of the side of the filter element body are machined with external threads.

[0009] As a further preferred embodiment of this technical solution, the connecting seat has four sets of slots arranged in a ring shape and at equal intervals inside. The lower end of the lower limit ring is fixed with four sets of blocks, which are engaged in the slots. A third sealing ring is bonded and fixed inside the connecting seat on the lower side of the slots, and the third sealing ring is fitted onto the lower side of the filter element body.

[0010] As a further preferred embodiment of this technical solution, a second sealing ring is bonded and fixed to the inner wall of the hollow seat, and the second sealing ring is fitted onto the side of the connecting seat.

[0011] As a further preferred embodiment of this technical solution, the telescopic rod and the spring are provided in four sets, and the four sets of telescopic rods and springs are respectively arranged at the lower end of the fixing ring. The hollow seat is provided with four sets of mounting grooves in a ring shape, and the bottom of the spring is fixed in the mounting groove.

[0012] As a further preferred embodiment of this technical solution, both the upper flange and the lower flange have a covering edge on their end face edges, and a rubber gasket is provided on the inner wall of the covering edge.

[0013] This utility model provides a quick-install filter element, which has the following beneficial effects:

[0014] (1) This utility model uses an upper flange and a lower flange to facilitate the stable installation of the filter element body inside the filter. The first sealing ring can seal the gap between the filter element body and the upper flange. The second sealing ring can seal the gap between the connecting seat and the hollow seat. The third sealing ring can seal the gap between the filter element body and the connecting seat, thereby ensuring that the filter element body avoids media leakage during use.

[0015] (2) This utility model can compress the connecting seat by using the fixing ring, telescopic rod and spring on the side of the connecting seat to make it enter the hollow seat, thereby changing the distance between the connecting seat and the stepped seat. After compressing the connecting seat, the lower part of the filter element body can be inserted into the connecting seat. At the same time, due to the locking block set on the lower limit ring, it can remind personnel to avoid the incorrect situation of the filter element body being installed upside down. Insert the lower part of the filter element body into the connecting seat, the locking block enters into the locking groove, and the lower part of the filter element body squeezes the third sealing ring to achieve a seal. When the lower limit ring pushes the fixing ring to contact the hollow seat, the spring is squeezed and then the filter element body is released. At this time, under the action of the spring, the filter element body is pushed upward, and the upper part of the filter element body enters into the stepped seat and squeezes the first sealing ring until the upper limit ring contacts the stepped seat, completing the installation. When disassembling, push the filter element body downward and squeeze the spring until the upper part of the filter element body can be moved out of the stepped seat. Then the filter element body can be pulled out from the connecting seat, which is convenient to operate.

[0016] (2) The upper flange and the lower flange of this utility model are provided with a covering edge on the end face edge. A rubber gasket is provided on the inner wall of the covering edge. When the quick-install filter element is connected to the pipeline, the pipeline flange can be inserted into the covering edge. Because the inner wall of the covering edge is provided with a rubber gasket, the connection between the upper flange and the lower flange and the pipeline flange is more tight, thereby enhancing the anti-leakage effect at the connection.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1-4 As shown in this embodiment, a quick-install filter element includes an upper flange 1, a filter element body 4, and a lower flange 7. The upper flange 1 is located above the lower flange 7. A stepped seat 2 is fixed to the lower middle of the upper flange 1. An upper limit ring 3 is threadedly connected to the upper side of the filter element body 4, and a lower limit ring 5 is threadedly connected to the lower side of the filter element body 4. The upper part of the filter element body 4 is inserted into the stepped seat 2, and the upper limit ring 3 is in contact with the side of the stepped seat 2. A hollow seat 8 is fixed to the upper middle of the lower flange 7. A connecting seat 10 is movably connected inside the hollow seat 8. The lower part of the filter element body 4 is inserted into the connecting seat 10, and the lower limit ring 5 is engaged with the connecting seat 10. A fixing ring 6 is fitted and fixed to the side of the connecting seat 10. A telescopic rod 9 is fixed to the lower end of the fixing ring 6. The telescopic rod 9 is inserted into the hollow seat 8, and a spring 14 is fixed to the bottom of the telescopic rod 9. The spring 14 is fixed inside the hollow seat 8.

[0024] like Figure 2 and Figure 4 As shown, a first sealing ring 11 is bonded and fixed inside the stepped seat 2. The first sealing ring 11 is in contact with the upper part of the filter element body 4. The gap between the stepped seat 2 and the filter element body 4 can be sealed by the first sealing ring 11. The inner walls of the upper limit ring 3 and the lower limit ring 5 are machined with internal threads. The upper and lower sides of the filter element body 4 are machined with external threads to facilitate the disassembly and assembly of the upper limit ring 3 and the lower limit ring 5 with the filter element body 4.

[0025] like Figure 1 , Figure 2 as well as Figure 4As shown, the connecting seat 10 has four sets of slots arranged in a ring shape at equal intervals inside. The lower limit ring 5 has four sets of locking blocks 12 fixed at its lower end. The locking blocks 12 are engaged in the slots. The locking blocks 12 and the slots can limit the filter element body 4 to prevent rotation. At the same time, it can remind personnel to avoid the filter element body 4 being held upside down during installation. A third sealing ring 15 is glued and fixed inside the connecting seat 10 on the lower side of the slots. The third sealing ring 15 is fitted on the lower side of the filter element body 4. The third sealing ring 15 can seal the gap between the connecting seat 10 and the filter element body 4. A second sealing ring 13 is glued and fixed to the inner wall of the hollow seat 8. The second sealing ring 13 is fitted on the side of the connecting seat 10. The second sealing ring 13 can seal the gap between the connecting seat 10 and the hollow seat 8, thereby reducing leakage.

[0026] like Figure 1 and Figure 2 As shown, there are four sets of telescopic rods 9 and springs 14. The four sets of telescopic rods 9 and springs 14 are respectively set at the lower end of the fixing ring 6. The hollow seat 8 has four sets of mounting slots 16 in a ring shape. The bottom of the spring 14 is fixed in the mounting slot 16. The mounting slot 16 facilitates the installation of the spring 14 and the telescopic rod 9.

[0027] like Figure 1 , Figure 2 as well as Figure 3 As shown, both the upper flange 1 and the lower flange 7 have a covering edge 17 on their end face edges. A rubber gasket 18 is provided on the inner wall of the covering edge 17. When the quick-connect filter element is connected to the pipeline, the pipeline flange can be inserted into the covering edge 17. Because the rubber gasket 18 is provided on the inner wall of the covering edge 17, the connection between the upper flange 1 and the lower flange 7 and the pipeline flange is tighter, thereby enhancing the anti-leakage effect at the connection.

[0028] This utility model provides a quick-install filter element. The specific working principle is as follows: During normal use, the upper limit ring 3 is threaded to the upper part of the filter element body 4, and the lower limit ring 5 is connected to the lower part of the filter element body 4. The upper flange 1 and lower flange 7 are fixed in the designated positions using external bolts. Then, the connecting seat 10 is pressed downwards by the fixing ring 6. The fixing ring 6 drives the telescopic rod 9 downwards and compresses the spring 14, causing the connecting seat 10 to enter the hollow seat 8. The lower part of the filter element body 4 is then inserted into the connecting seat 10, allowing the locking block 12 to enter the slot until the lower limit ring 5 contacts the connecting seat 10. Then, the fixing ring 6 is released. At this time, under the action of the spring 14, the connecting seat 10 is pushed downwards, causing the connecting seat 10 to drive the filter element body 4 upwards. The upper part of the filter element body 4 is inserted into the stepped seat 2, completing the installation. For disassembly, simply push the fixing seat downwards again. This facilitates operation. Simultaneously, three sets of sealing rings can seal the gaps between components, reducing media leakage during filtration.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
