Description

Technical Field

[0001] This utility model relates to the field of filter element technology, and specifically to a filter element installation structure. Background Technology

[0002] The filter element is the heart of the filter, as its name suggests. The filter element, and the core principle of the filter, is to purify raw materials and facilitate their reuse. Filter elements are commonly used in oil filtration, water filtration, and air filtration. They remove small amounts of impurities from the filter medium, protecting the equipment and ensuring air cleanliness. When fluid passes through a filter element with a certain precision, impurities are blocked, while clean fluid flows out.

[0003] Currently, existing filter cartridges are mostly fixed to the filter by screwing them on. However, the frequent screwing of the filter cartridges makes the threads very prone to wear, which greatly reduces the service life of the device and results in poor performance. Therefore, it is necessary to design a filter cartridge installation structure to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a filter element installation structure. By setting a fixing ring, multiple sets of positioning posts and rubber heads are provided on the inner side of the fixing ring. With the cooperation of the transmission mechanism, after the filter element is inserted between the mounting plate and the fixing ring, the multiple sets of positioning posts can drive the rubber heads to move inward synchronously, so that the multiple sets of rubber heads can evenly press against the side of the filter element, thereby quickly and effectively clamping and positioning the filter element, so as to realize the rapid installation of the filter element. The operation is simple and convenient, and the effect is good, thus solving the above-mentioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter element mounting structure, comprising: The mounting plate has a fixing ring on its top side, and a filter element is connected through the fixing ring and the mounting plate. A cover is provided on the top of the filter element near the fixing ring. The fixed ring has an annular cavity inside, and a support ring is rotatably installed inside the annular cavity. The four ends of the inner side of the fixed ring are all connected to positioning posts. A transmission mechanism is provided between the end of the positioning post extending into the annular cavity and the annular cavity, and a rubber head is provided at the other end of the positioning post. Clamping mechanisms are provided on both sides of the fixing ring, and a snap-fit ​​assembly is provided between the fixing ring and the cover.

[0006] Preferably, the transmission mechanism includes a toothed ring disposed on the top side of the support ring, and the four ends of the inner side of the annular cavity are rotatably connected to threaded rods facing the positioning post through bearings. One end of the threaded rod is screwed into the positioning post through a thread, and the other end of the threaded rod is fixed with a gear that meshes with the toothed ring. A guide assembly is provided between the positioning post and the fixed ring, and one end of the threaded rod extends out of the fixed ring and is provided with a fixing handle.

[0007] Preferably, the guide assembly includes a guide post fixedly connected to the bottom side of the positioning post near one end of the threaded rod, and a guide groove matching the guide post is provided on the inner side of the annular cavity.

[0008] Preferably, the outer side of the support ring is provided with a plurality of limiting posts, and the inner wall of the annular cavity is provided with a limiting groove that matches the limiting posts.

[0009] Preferably, the clamping mechanism includes fixed frames symmetrically arranged on both sides of the fixed ring. An L-shaped clamping plate is slidably connected to one end of the fixed frame near the fixed ring, and a spring is fixedly connected between the other end of the fixed frame and the L-shaped clamping plate. The top of the L-shaped clamping plate can abut against the side of the cover.

[0010] Preferably, a connecting rod is fixed inside the fixed frame, and the spring and L-shaped card plate are slidably sleeved on the outside of the connecting rod.

[0011] Preferably, the snap-fit ​​assembly includes snap pins disposed at four ends on the top side of the fixing ring, and each of the four ends of the cover is provided with snap holes that match the snap pins.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: By setting a fixing ring, the inner side of the fixing ring is equipped with multiple sets of positioning posts and rubber heads. With the cooperation of the transmission mechanism, after the filter element is inserted between the mounting plate and the fixing ring, the multiple sets of positioning posts can drive the rubber heads to move inward synchronously, so that the multiple sets of rubber heads can evenly press against the side of the filter element, thereby quickly and effectively clamping and positioning the filter element, so as to realize the rapid installation of the filter element. The operation is simple and convenient, and the effect is good. Furthermore, by symmetrically setting a clamping mechanism consisting of a fixing frame, a spring, and an L-shaped clamping plate on both sides of the fixing ring, when the cover is attached to the top side of the fixing ring, the two sets of L-shaped clamping plates can be reset and clamped to the top side of the cover, thereby further limiting and reinforcing the filter element, thus greatly ensuring the stability of the filter element during installation. By setting a locking post and locking hole between the fixing ring and the cover to form a locking assembly, the connection strength between the cover and the fixing ring can be greatly enhanced, thereby greatly improving the stability of the filter element positioning and installation.

The four ends of the inner side of the fixed ring 2 are all connected to the positioning pins 6. A transmission mechanism is provided between the end of the positioning pin 6 extending into the annular cavity 5 and the annular cavity 5, and a rubber head 7 is provided at the other end of the positioning pin 6. The transmission mechanism includes a toothed ring 9 disposed on the top side of the support ring 8. The four ends of the inner side of the annular cavity 5 are rotatably connected to the positioning post 6 via bearings. One end of the threaded rod 10 is screwed into the positioning post 6 via threads, and the other end of the threaded rod 10 is fixed with a gear 11 that meshes with the toothed ring 9. A guide assembly is provided between the positioning post 6 and the fixed ring 2. One end of one of the threaded rods 10 extends out of the fixed ring 2 and is provided with a fixing handle 12.

[0018] In use, the filter element 3 can be inserted between the mounting plate 1 and the fixing ring 2, and the cover 4 can be placed against the fixing ring 2. Then, the fixing handle 12 can be turned to drive the threaded rod 10 to rotate. The threaded rod 10 can drive the gear ring 9 to move through the gear 11, so that the gear ring 9 drives the support ring 8 to rotate in the annular cavity 5. Then, the support ring 8 can drive multiple sets of gears 11 to rotate synchronously through the gear ring 9, so that the gears 11 drive the corresponding threaded rod 10 to rotate. Then, the threaded rod 10 can drive the positioning post 6 to move. With the cooperation of the guide component, the positioning post 6 can drive the rubber head 7 to extend in a straight line towards the filter element 3, so that multiple sets of rubber heads 7 are evenly pressed against the side of the filter element 3, thereby effectively clamping and positioning the filter element 3 to achieve quick installation of the filter element 3.

[0019] The guiding assembly includes a guide post 13 fixedly connected to the bottom side of the positioning post 6 near one end of the threaded rod 10, and a guide groove 14 matching the guide post 13 is provided on the inner side of the annular cavity 5.

[0023] A connecting rod 20 is fixed inside the fixed frame 17, and the spring 19 and the L-shaped clamping plate 18 are slidably sleeved on the outside of the connecting rod 20. Based on this, the connecting rod 20 can limit the position of the spring 19 and the L-shaped clamping plate 18, thereby greatly ensuring their stability during movement.

[0024] In use, the two L-shaped clamping plates 18 can be pulled outward in advance, so that the L-shaped clamping plates 18 slide within the fixed frame 17 and squeeze the spring 19, thereby opening the two L-shaped clamping plates 18. Then, the filter element 3 can be inserted between the fixed ring 2 and the mounting plate 1. After releasing the L-shaped clamping plates 18, the two L-shaped clamping plates 18 can be reset and locked onto the top side of the cover 4 under the rebound of the spring 19, thereby further limiting and reinforcing the filter element 3, thus greatly ensuring the stability of the filter element 3 during installation.

[0025] The snap-fit ​​assembly includes snap posts 21 at the four ends of the top side of the fixing ring 2, and snap holes 22 at the four ends of the cover 4 that match the snap posts 21.

[0026] By aligning and inserting the clip 21 into the clip hole 22, the connection strength between the cover 4 and the fixing ring 2 can be greatly enhanced, thereby greatly improving the stability of the filter element 3 in positioning and installation.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
