Description

Technical Field

[0001] This utility model relates to the field of dust collector filter cartridges, and more specifically, to a bottom anti-detachment structure for dust collector filter cartridges. Background Technology

[0002] As a core component of dust collectors, dust filter cartridges are typically made of high-strength fiber materials, possessing high filtration accuracy and air permeability. During the filtration process, when dust-laden gas passes through the filter cartridge, dust particles are intercepted by the surface of the cartridge, while clean gas is discharged through the cartridge. However, during use, most dust filter cartridges are prone to the filter screen falling off at the bottom after repeated cleaning, which can lead to a decrease in dust removal efficiency when the filter cartridge is used inside the dust collector.

[0003] The utility model with authorization announcement number CN 222266533 U relates to the field of dust collector filter cartridge technology, specifically a bottom anti-detachment device for a dust collector filter cartridge. The dust collector filter cartridge bottom anti-detachment device includes: a dust collector filter cartridge body, a fixing strap, and a top cover. The fixing strap is provided on the surface of the dust collector filter cartridge body, and the top cover is provided on the top of the dust collector filter cartridge body. The beneficial effect is that by pushing the push rod, the push rod can push the connected slider when it moves, thereby allowing the slider to slide on the surface of the anti-detachment cover. Simultaneously, the push rod can compress the first spring when it moves, and the slider can push the connecting rod connected to the surface when it moves, thereby allowing the connecting rod to push the locking rod when it moves, thus allowing the locking rod to move inside the anti-detachment cover, enabling the locking rod to separate from the dust collector filter cartridge body. Therefore, the bottom anti-detachment device for the dust collector filter cartridge can prevent the internal filter screen from falling off during use.

[0004] The aforementioned structure uses a combination of rods and springs to limit the cover plate, which is not only complex and difficult to assemble, install, and adjust, but also prone to interfering with the surface of the cover plate, making it difficult to quickly align during installation. It has poor adaptability and needs to be improved. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a bottom anti-detachment structure for a dust collector filter cartridge. By installing a cover plate at the bottom of the filter cartridge, the internal filter element can be filtered, facilitating disassembly and cleaning. Furthermore, a locking groove is set through a fixed plate, and a circular limit rod is installed in conjunction with a rotating adjustment head. During installation, it can be turned to avoid interference. After positioning and connection, it can be extended and retracted for alignment and locking. The structure is simple, highly stable, convenient to connect and use, and prevents detachment.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A dust collector filter cartridge bottom anti-detachment structure includes a filter cartridge, a threaded cylinder fixedly connected to the lower surface of the filter cartridge, a cover plate threadedly installed on the outer surface of the threaded cylinder, the cover plate being aligned and connected directly below the filter cartridge, a fixed plate fixedly connected to the lower end of the outer surface of the filter cartridge, a positioning notch provided on the surface of the fixed plate, a snap-fit ​​groove provided on the upper surface of the fixed plate, the snap-fit ​​groove being aligned with one end of the positioning notch, fixed blocks fixedly connected to both sides of the outer surface of the cover plate, a rotating head rotatably mounted inside the fixed blocks, an adjusting head fixedly connected to one end of the rotating head, a damping through hole provided inside the adjusting head, a damping rubber pad fixedly attached to the inner surface of the damping through hole, a circular limiting rod slidably connected inside the damping through hole, one end of the circular limiting rod being inserted into the inside of the positioning notch, and the circular limiting rod being combined and connected to both sides of the fixed plate.

[0008] Furthermore, a hexagonal head is fixedly connected to one end of the circular limiting rod, and the hexagonal head is located below the adjusting head.

[0009] Furthermore, a bending head is fixedly connected to one end of the circular limiting rod, and the bending head is snapped onto the upper surface of the fixed plate.

[0010] Furthermore, a snap-fit ​​connector is fixedly connected to one side surface of the bending head. The snap-fit ​​connector is elastically snapped into the inside of the snap-fit ​​groove. It is connected to the hexagonal head through a circular limiting rod. Combined with the snap-fit ​​connector of the bending head, it can limit the two ends to prevent it from falling off. It can also be pushed and adjusted for alignment and snap-fit, which is convenient for limiting support and is efficient and stable.

[0011] Furthermore, the positioning notches and snap-fit ​​grooves are distributed at equal circumferential angles on the surface of the fixed plate, and their positions correspond to each other.

[0012] Furthermore, there are two fixing blocks and two adjusting heads, which are symmetrically connected to the two sides of the cover plate.

[0013] Furthermore, the circular limiting rod is slidably installed inside the adjusting head and located on the side of the cover plate. With the circumferentially distributed positioning notches and the symmetrical adjusting heads on both sides, it can be aligned and snapped after threaded installation, which is conducive to accurate connection and prevents detachment, and is convenient and stable.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution uses a cover plate installed at the bottom of the filter cylinder to filter the internal filter element, which is convenient for disassembly and cleaning. The fixed plate is set with a snap-fit ​​groove, and a circular limit rod is installed with the rotating adjustment head. During installation, it can be turned to avoid interference. After positioning and connection, it can be extended and retracted for snap-fit ​​and limit. The structure is simple, stable, convenient for connection and use, and avoids falling off.

[0016] (2) The hexagonal head is connected by a circular limiting rod and a bending head is connected by a snap-fit ​​connector. Both ends can be limited to prevent them from falling off. The adjustment can be pushed to make them aligned and snap-fit, which is convenient for limiting support and is efficient and stable.

[0017] (3) By using the circumferentially distributed positioning notch, combined with the symmetrical adjustment heads on both sides, the threaded installation can be aligned and snapped together, which is conducive to accurate connection and prevents detachment, and is convenient and stable.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , Figure 4 and Figure 5A dust collector filter cartridge bottom anti-detachment structure includes a filter cartridge 1. A threaded cylinder 11 is fixedly connected to the lower surface of the filter cartridge 1. A cover plate 12 is threadedly installed on the outer surface of the threaded cylinder 11. The cover plate 12 is aligned and connected directly below the filter cartridge 1, allowing for convenient and efficient threaded installation and positioning. A fixing plate 13 is fixedly connected to the lower end of the outer surface of the filter cartridge 1. The surface of the fixing plate 13 has a positioning notch 14, and the upper surface of the fixing plate 13 has a snap-fit ​​groove 15, which is aligned with one end of the positioning notch 14. Fixing blocks 16 are fixedly connected to both sides of the outer surface of the cover plate 12. A rotating head 17 is rotatably installed inside the fixing block 16. An adjusting head 2 is fixedly connected to one end of the rotating head 17. By rotating the rotating head 17, the orientation of the adjusting head 2 can be manually changed, thereby rotating and adjusting the position with the circular limit rod 22 to avoid interference with the cover plate 12. This facilitates quick alignment and installation and fixation onto the threaded cylinder 11, making it convenient, efficient, and easy to avoid obstacles. The adjusting head 2 has a damping through hole 21 inside. A damping rubber pad is fixedly attached to the inner surface of the cover plate 13. A circular limiting rod 22 is slidably connected inside the damping through hole 21. One end of the circular limiting rod 22 is inserted into the positioning notch 14. The circular limiting rod 22 is connected to both sides of the fixed plate 13. When the cover plate 12 is threaded on, the adjusting head 2 is rotated 90 degrees in conjunction with the rotating head 17 to adjust the circular limiting rod 22 to the horizontal direction. Then the cover plate 12 is threaded on without interfering with the fixed plate 13. After positioning, the adjusting head can be turned around. In direction 2, vertically adjust the circular limiting rod 22 and point the bending head 24 outward. Then push the hexagonal head 23 to push the circular limiting rod 22 upward, so that it can be inserted into the positioning notch 14. Then rotate the circular limiting rod 22 and adjust the bending head 24 inward. The locking head 25 is engaged with the locking groove 15, which can lock and position each other to prevent loosening. In this way, the circular limiting rod 22 restricts the cover plate 12 to prevent rotation, thus preventing it from falling off. It is convenient, stable, and easy to adjust and use.

[0027] Please see Figure 2 and Figure 3 One end of the circular limiting rod 22 is fixedly connected to a hexagonal head 23, which is located below the adjusting head 2. The other end of the circular limiting rod 22 is fixedly connected to a bending head 24, which is snapped onto the upper surface of the fixed plate 13. A snap-fit ​​connector 25 is fixedly connected to one side surface of the bending head 24, which is elastically snapped into the inside of the snap-fit ​​groove 15. By connecting the hexagonal head to the circular limiting rod and the snap-fit ​​connector to the bending head, both ends can be limited to prevent them from falling off. The adjustment can also be pushed to perform alignment and snap-fit, which is convenient for limiting support and is efficient and stable.

[0028] Please see Figure 1 and Figure 2The positioning notch 14 and the snap-fit ​​groove 15 are distributed at equal circumferential angles on the surface of the fixed plate 13 and their positions correspond to each other. There are two fixed blocks 16 and two adjusting heads 2, which are symmetrically connected to the two sides of the cover plate 12. The circular limiting rod 22 is slidably installed inside the adjusting head 2 and is located on the side of the cover plate 12. Through the circumferentially distributed positioning notch, combined with the symmetrical adjusting heads on both sides, it can be aligned and snapped after threaded installation, which is conducive to accurate connection and prevents detachment, and is convenient and stable.

[0029] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
