Description

Technical Field

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

[0002] The filter element is the core component of a filtration device, acting like a "sieve" or "purifier" to intercept and remove impurities from fluids such as water, air, and oil.

[0003] Currently, filter elements are generally placed in filter cartridges. However, current filter cartridges lack a clamping structure, causing the bottom of the filter element to be unstable and prone to tilting or swaying. Furthermore, they cannot accommodate filter elements of the same height but different diameters, which presents certain limitations. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a filter element and a filter element holder for fixing the filter element, which can quickly clamp filter element bodies of different diameters, so as to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a filter element holder for fixing filter elements, including a lower pressure ring and a base installed inside the filter cylinder. The lower pressure ring and the base are arranged parallel to each other, one above the other. The inner wall of the base is provided with multiple connected sliding grooves that are evenly distributed in a ring structure. A slider is slidably installed in each of the sliding grooves. A clamping block is installed on the upper surface of each slider. The inner side of each clamping block is recessed to form a clamping groove. Multiple clamping grooves are combined to form a clamping cavity. A drive mechanism for driving the lower pressure ring to rise and fall is installed on the base.

[0006] As a preferred technical solution, the outer side of the clamping block is provided with a guide portion at an angle, and the inner side of the pressure ring protrudes to form a squeezing portion with an annular structure. The end face of the squeezing portion is set to abut against the guide portion.

[0007] As a preferred technical solution, the drive mechanism includes an adjusting sleeve, a lead screw, a bearing, a positioning rod, a gripping rod, and multiple connecting plates. The outer wall of the base has multiple positioning holes in a ring structure. One end of each positioning rod passes through the positioning hole and is fixedly connected to the lower pressure ring, while the other end extends through the outside of the filter cylinder to the outside. The bearing is embedded in the end face of the base away from the lower pressure ring. The filter cylinder has a through hole opposite the inner ring of the bearing. The adjusting sleeve is threaded onto the lead screw. One end of the lead screw passes through the through hole and is installed in the inner ring of the bearing, while the other end is fixedly connected to the gripping rod. A connecting plate is installed between the adjusting sleeve and the positioning rod.

[0008] As a preferred technical solution, a sealing sleeve is installed in each positioning hole, and the gap between the positioning hole and the positioning rod is sealed by the sealing sleeve.

[0009] As a preferred technical solution, both the groove and the slider have a "T" shaped cross-section.

[0010] As a preferred technical solution, a compression spring is installed between the slider and the slide groove.

[0011] A filter element, such as a filter element holder for fixing the filter element, includes a filter element body, one end of which is fitted with a clamping plate that extends through a lower pressure ring into a clamping cavity and is clamped and fixed by inwardly converging clamping blocks.

[0012] The beneficial effects of this utility model are: the utility model has a simple structure and the operating end of the drive mechanism is set on the outside, so that the clamping operation of filter elements of different diameters can be completed directly inside the filter cylinder. The operation process is simple. As the lower pressure ring descends, multiple clamping blocks can be squeezed at one time, so that the clamping blocks can come together and clamp the clamping plate at the same time to ensure the stability of the bottom of the filter element body and avoid tilting or swinging.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a filter element holder for fixing filter elements according to the present invention includes a lower pressure ring 3 and a base 1 installed inside the filter cylinder. The lower pressure ring 3 and the base 1 are arranged parallel to each other, one above the other. The inner wall of the base 1 is provided with multiple connected sliding grooves 16 that are evenly distributed in a ring structure. A slider 14 is slidably installed in each sliding groove 16. A clamping block 10 is installed on the upper surface of each slider 14. A clamping groove 15 is formed by recessing on the inner side of each clamping block 10. Multiple clamping grooves 15 are combined to form a clamping cavity. A drive mechanism for driving the lower pressure ring 3 to rise and fall is installed on the base 1.

[0023] In this embodiment, the outer side of the clamping block 10 is provided with a guide portion 11 at an angle, and the inner side of the pressure ring 3 protrudes to form a compression portion 13 with an annular structure. The end face of the compression portion 13 is provided to abut against the guide portion 11.

[0024] In this embodiment, the driving mechanism includes an adjusting sleeve 18, a lead screw 6, a bearing 8, a positioning rod 4, a gripping rod 7, and multiple connecting plates 5. The outer wall of the base 1 has multiple positioning holes in a ring structure. One end of each positioning rod 4 passes through the positioning hole and is fixedly connected to the lower pressure ring 3, while the other end extends through the outside of the filter cylinder to the outside. The bearing 8 is embedded in the end face of the base 1 away from the lower pressure ring 3. The filter cylinder has a through hole opposite the inner ring of the bearing 8. The adjusting sleeve 18 is threaded to the lead screw 6. One end of the lead screw 6 passes through the through hole and is installed in the inner ring of the bearing 8, while the other end is fixedly connected to the gripping rod 7. A connecting plate 5 is installed between the adjusting sleeve 18 and the positioning rod 4.

[0025] In this embodiment, a sealing sleeve 9 is installed in each positioning hole, and the gap between the positioning hole and the positioning rod 4 is sealed by the sealing sleeve 9. The base is bonded and fixed in the filter cylinder, and the outer ring of the base is sealed with the inner wall of the filter cylinder. The positioning hole is sealed by the sealing sleeve to prevent the internal liquid from leaking out from the bottom of the filter cylinder.

[0026] In this embodiment, both the groove 16 and the slider 14 have a "T" shaped cross-section.

[0027] In this embodiment, a compression spring 17 is installed between the slider 14 and the slide groove 16.

[0028] A filter element includes a filter element body 2, one end of which is fitted with a clamping plate 12. The clamping plate 12 extends through a lower pressure ring 3 into a clamping cavity and is clamped and fixed by an inwardly converging clamping block 10.

[0029] Initial state:

[0030] The clamping plate 12 at the bottom of the filter element body 2 is located inside the base 1 and is situated in the clamping cavity formed by multiple clamping blocks 10. The clamping blocks 10 are in an outward separation state under the action of the compression spring 17. At this time, the diameter of the clamping cavity is relatively large, providing space to accommodate clamping plates 12 of different diameters. The lower pressure ring 3 is connected to the adjusting sleeve 18 through the positioning rod 4 and the connecting plate 5 and is in a higher position. Its squeezing part 13 does not contact the flow guiding part 11 of the clamping block 10.

[0031] When clamping is required, the operator can directly rotate the handle 7 outside the filter cylinder to drive the lead screw 6 to rotate. This is the only input for the entire operation, which is simple and direct. It does not move axially on its own, but drives the adjusting sleeve 18, which is threaded to it, to move downward along the axial direction of the lead screw 6.

[0032] The adjusting sleeve 18 drives the positioning rod 4 to slide in the positioning hole through the connecting plate 5, so that the lower pressure ring 3 moves downward smoothly as a whole. All complex actions are automatically completed inside the equipment. The operator can control it by rotating it externally. When the lower pressure ring 3 moves downward, its inner annular extrusion part 13 slides along the inclined guide part 11 on the outside of the clamping block 10, generating a radial force towards the center. This force pushes all the clamping blocks 10 to slide synchronously towards the center along the slide groove 16.

[0033] As the clamping block 10 moves inward, the diameter of the clamping cavity formed by its inner clamping groove 15 decreases, thereby gripping and fixing the clamping plate 12 at the bottom of the filter element body 2; the T-shaped structure of the sliding groove 16 and the slider 14 effectively prevents the clamping block 10 from coming out when subjected to force.

[0034] After clamping, the bottom of the filter element body 2 is firmly clamped, preventing it from tilting or swinging inside the filter cylinder. The self-locking thread of the lead screw 6 prevents the mechanism from loosening on its own under vibration.

[0035] By rotating the handle 7 to control the downward stroke of the pressure ring 3, the radial movement distance of the clamping block 10 can be precisely adjusted, thereby changing the final diameter of the clamping cavity. This design enables the structure to adapt to and reliably clamp clamping plates 12 and filter element bodies 2 of different diameters.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
