Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter media technology, and more specifically, to a filter media that is easy to assemble and disassemble. Background Technology
[0002] In fields such as water treatment, air purification, and industrial liquid filtration, filters are widely used as key equipment in various purification systems. Their core component, filter media, needs to be replaced regularly to ensure filtration efficiency and system performance. Currently, when maintenance personnel replace filter media, they often need to go through complicated disassembly steps to remove the filter media from the filter. This operation is not only time-consuming and labor-intensive, but may also cause damage to the filtration system or leakage of pollutants due to improper operation, affecting work efficiency and environmental safety. Traditional filter media installation methods mostly use bolt fixing or snap-fit connection, which requires operators to use special tools for multi-step disassembly and assembly. This is especially inconvenient in confined spaces or emergency situations, and it is difficult to meet the requirements of modern industry for rapid maintenance and efficient operation.
[0003] In continuous production and automated factory environments, the time window for equipment maintenance is extremely limited, and every downtime can lead to significant economic losses. Therefore, the maintenance efficiency of filtration equipment directly affects the overall operating status of the production line. Existing filter media fixing structures mostly adopt traditional mechanical locking methods, which are cumbersome to disassemble and assemble and lack standardization. This not only increases the workload of technicians but also prolongs equipment downtime. Utility Model Content

A quick-assembly mechanism is provided inside the shell. The quick-assembly mechanism includes insertion rods, a filter media body, a fixing sleeve, a snap-fit rod, a slot, a slider, a locking block, a push block, and a limiting mechanism. Multiple sets of insertion rods are fixed inside the shell. The filter media body is inserted into multiple sets of insertion rods. The fixing sleeve is fixed to the top surface of the top rod. The snap-fit rod is fixed to the top of multiple sets of insertion rods. Multiple sets of sliders slide on the outer wall of the fixing sleeve. The locking block is fixed to the bottom end of multiple sets of sliders. The push block is fixed to the top end of multiple sets of sliders. The limiting mechanism includes a limiting sleeve, a connecting sleeve, a sliding rod, a rotating sleeve, a limiting block, a limiting hole, and an unlocking hole. The limiting sleeve slides on the outer wall of the fixing sleeve. The connecting sleeve is fixed to the bottom end of the limiting sleeve. Multiple sets of sliding rods are fixed to the bottom surface of the connecting sleeve. The rotating sleeve rotates on the outer wall of the fixing sleeve. The limiting block is fixed to the bottom end of multiple sets of sliding rods. Multiple sets of limiting holes are distributed on the top surface of the rotating sleeve. The unlocking hole is located at one end of the multiple sets of limiting holes.
[0008] The present invention is further configured such that an inner screen is fixedly provided inside the outer shell, and the filter media is disposed between the inner screen and the outer shell and is inserted into multiple sets of rods. This structure forms a double-layer filtration system. The inner screen provides stable support for the filter media, preventing deformation and collapse, while ensuring uniform distribution of the filter medium, thereby improving filtration efficiency and service life.
[0009] The present invention is further configured such that the outer wall of the fixed sleeve is provided with a sliding groove, and the sliding groove is provided in multiple sets and is slidably connected to multiple sets of push blocks respectively. The design of multiple sets of sliding grooves makes the movement trajectory of the push blocks precise and controllable, ensuring that the movement of the push blocks is smooth and stable, achieving uniform force, and improving the stability and reliability of the locking mechanism.
[0010] The present invention is further configured such that the outer walls of the multiple sets of push blocks are all set as inclined surfaces, and the top of the limiting sleeve is provided with rounded corners.

The rounded corner design reduces frictional resistance, avoids jamming, and improves operational safety, preventing scratches to the operator.
[0011] The present invention is further provided in that a push spring is provided between the inner wall of the multiple sets of push blocks and the slide groove. The push spring provides a continuous and stable elastic restoring force for the locking block, ensuring that it can automatically return to the initial position after unlocking, simplifying the operation process, while enhancing the locking stability and preventing accidental loosening due to vibration.
[0012] The present invention is further configured such that a guide plate is fixedly provided on the inner wall of the limiting sleeve, and a guide groove is provided on the outer wall of the fixed sleeve. Multiple sets of the guide plate and the guide groove are provided and slidably connected. This guiding system ensures that the limiting sleeve moves smoothly along the preset track, prevents rotation or deviation, enhances structural stability, reduces operating resistance, and improves disassembly and assembly efficiency.
[0013] The present invention is further configured such that a sliding hole is provided in the snap-fit rod, a top block is slidably provided in the sliding hole, and a compression spring is connected between the bottom surface of the top block and the bottom surface of the sliding hole. This elastic structure provides buffer protection and self-spring function for the snap-fit rod, reduces installation impact force, extends component life, and can automatically pop out and separate after unlocking, speeding up disassembly.
[0014] This utility model is further configured such that each of the multiple sets of sliding rods is provided with a tension spring on its outer side, the top of each of the multiple sets of tension springs is fixedly connected to the bottom surface of the connecting sleeve and the bottom end is connected to a connecting ring, the bottom surface of each of the multiple sets of connecting rings is connected to an arc-shaped block, the top surface of the rotating sleeve is provided with an annular groove, and the multiple sets of arc-shaped blocks slide in the annular groove. This combined structure constitutes a high-efficiency transmission system. The tension spring provides stable tension to keep the limiting device in a pre-tightened state, and the arc-shaped blocks slide in the annular groove to reduce rotational resistance, making the operation easier and smoother, while ensuring the coordinated movement and reliable locking of the overall structure.

[0029] Please see Figures 1-5 A filter media that is easy to assemble and disassemble includes a housing 1 and a top cover 2. A quick-assembly mechanism is provided inside the housing 1. The quick-assembly mechanism includes insertion rods 3, filter media bodies 4, fixing sleeves 5, snap-fit rods 6, slots 7, sliders 8, locking blocks 9, push blocks 10, and a limiting mechanism. Multiple sets of insertion rods 3 are fixed inside the housing 1. The filter media bodies 4 are inserted into multiple sets of insertion rods 3. The fixing sleeve 5 is fixed to the top surface of the top rod. The snap-fit rods 6 are fixed to the top ends of the multiple sets of insertion rods 3. Multiple sets of sliders 8 slide on the outer wall of the fixing sleeve 5. The locking blocks 9 are fixed to the bottom ends of the multiple sets of sliders 8. The push blocks 10 are fixed to... The top of the multiple sets of sliders 8 has a limiting mechanism including a limiting sleeve 11, a connecting sleeve 12, a sliding rod 13, a rotating sleeve 14, a limiting block 15, a limiting hole 16, and an unlocking hole 17. The limiting sleeve 11 slides on the outer wall of the fixed sleeve 5, the connecting sleeve 12 is fixed to the bottom end of the limiting sleeve 11, the sliding rod 13 is provided in multiple sets and fixed to the bottom surface of the connecting sleeve 12, the rotating sleeve 14 rotates on the outer wall of the fixed sleeve 5, the limiting block 15 is fixed to the bottom end of the multiple sets of sliding rods 13, the limiting hole 16 is provided in multiple sets and distributed on the top surface of the rotating sleeve 14, and the unlocking hole 17 is provided at one end of the multiple sets of limiting holes 16.
[0030] An inner screen 18 is fixedly installed inside the outer shell 1. The filter media 4 is placed between the inner screen 18 and the outer shell 1 and is inserted into multiple sets of insert rods 3. The inner screen 18 provides structural support for the filter media 4 to prevent the filter media 4 from deforming under working pressure. At the same time, the insert rods 3 ensure that the filter media 4 is accurately positioned, ensuring uniform distribution of the filter medium and improving filtration efficiency.
[0031] The outer wall of the fixed sleeve 5 is provided with a sliding groove 19. Multiple sets of sliding grooves 19 are provided and are slidably connected to multiple sets of push blocks 10 respectively. The multiple sets of sliding grooves 19 form a preset track, constrain the movement direction of the push block 10, ensure that the push block 10 moves smoothly along the fixed track, realize multi-point synchronous engagement, and improve the stability of the locking mechanism.
[0032] The outer walls of multiple push blocks 10 are all set as inclined surfaces, and the top of the limiting sleeve 11 is provided with rounded corners. The inclined surface design of the push block 10 enables the radial force to be converted into the lateral movement of the push block 10 when the limiting sleeve 11 is pressed down, while the rounded corners of the limiting sleeve 11 reduce contact friction, making the sliding smoother and reducing wear.
[0033] Push springs 20 are provided between the inner walls of multiple push blocks 10 and the slide grooves 19. The push springs 20 store energy in the compressed state. When the limit sleeve 11 is released from the constraint, the push springs 20 release energy to push the push blocks 10 back to their original positions, automatically completing the unlocking action, simplifying the operation process and enhancing the reliability of the system.
[0034] The inner wall of the limiting sleeve 11 is fixedly provided with a guide plate 21, and the outer wall of the fixed sleeve 5 is provided with a guide groove 22. Multiple sets of guide plates 21 and guide grooves 22 are provided and slidably connected. The guide plate 21 slides in the guide groove 22 to prevent the limiting sleeve 11 from rotating or deviating during the movement, ensuring that the limiting sleeve 11 moves strictly along the axial direction and improving the accuracy and stability of the overall mechanism.
[0035] The snap-fit rod 6 has a sliding hole 23, and a top block 24 is slidably disposed in the sliding hole 23. A compression spring 25 is connected between the bottom surface of the top block 24 and the bottom surface of the sliding hole 23. During installation, the top block 24 is compressed into the sliding hole 23 and compresses the compression spring 25. During unlocking, the compression spring 25 releases energy to push the top block 24, thereby pushing the snap-fit rod 6 to separate from the fixed sleeve 5, realizing the function of quick and automatic pop-out.
[0036] Multiple sets of slide rods 13 are equipped with tension springs 26 on their outer sides. The top of each set of tension springs 26 is fixedly connected to the bottom surface of the connecting sleeve 12, and the bottom end is connected to a connecting ring 27. The bottom surface of each set of connecting rings 27 is connected to an arc-shaped block 28. The top surface of the rotating sleeve 14 is provided with an annular groove 29. The multiple sets of arc-shaped blocks 28 slide in the annular groove 29. When the rotating sleeve 14 rotates, it drives the arc-shaped blocks 28 to move through the annular groove 29. The arc-shaped blocks 28 pull the slide rods 13 through the connecting rings 27 and tension springs 26, realizing the conversion from rotational motion to linear motion. The tension springs 26 also provide buffering and reset functions.
[0037] In this embodiment, when the filter media 4 needs to be installed, the filter media 4 is inserted with multiple sets of insert rods 3 and placed between the outer shell 1 and the inner screen 18. Then, the top cover 2 is pressed against the top surface of the outer shell 1 and multiple sets of snap-fit rods 6 are inserted into the fixing sleeve 5. The limiting sleeve 11 is pushed against the outer wall of multiple sets of push blocks 10 and the multiple sets of tension springs 26 are stretched, so that the multiple sets of push blocks 10 slide along the slide groove 19 and squeeze the push spring 20. The multiple sets of push blocks 10 push the slider 8 so that the snap-fit block 9 is engaged in the slot 7. At this time, the multiple sets of limiting blocks 15 are in the unlocking hole 17. The rotating sleeve 14 is rotated clockwise so that the multiple sets of slide rods 13 slide into the limiting hole 16. The multiple sets of limiting blocks 15 are pressed against the outer wall of the rotating sleeve 14 to limit the limiting sleeve 11. The filter media 4 can be quickly installed and fixed by operating in sequence.
[0038] More specifically, when the filter body 4 needs to be disassembled, the rotating sleeve 14 is rotated counterclockwise so that multiple sets of limiting blocks 15 slide along the limiting hole 16 into the unlocking hole 17, thereby releasing the multiple sets of limiting blocks 15 from contact with the outer wall of the rotating sleeve 14. Multiple sets of tension springs 26 pull the connecting sleeve 12 and the limiting sleeve 11, and the multiple sets of limiting sleeves 11 release the contact with the multiple sets of push blocks 10. Multiple sets of push springs 20 reset and push the push blocks 10 to slide along the slide groove 19. Multiple sets of push blocks 10 pull the locking block 9 through the slider 8 to disengage it from the locking groove 7, thereby releasing the locking of the locking rod 6. Multiple sets of compression springs 25 reset and push the top block 24. The top block 24 pushes the fixing sleeve 5, thereby separating the locking rod 6 from the fixing sleeve 5, releasing the top cover 2 from fixing the filter body 4, and then the filter body 4 can be disassembled.
[0039] In summary, when using or operating the entire equipment: when it is necessary to install the filter media 4, insert the filter media 4 with the multiple sets of insert rods 3 and place it between the outer shell 1 and the inner screen 18. Then, abut the top cover 2 against the top surface of the outer shell 1 and insert the multiple sets of snap-fit rods 6 into the fixing sleeve 5. Push the limiting sleeve 11 against the outer wall of the multiple sets of push blocks 10 and stretch the multiple sets of tension springs 26, so that the multiple sets of push blocks 10 slide along the slide groove 19 and squeeze the push spring 20. The multiple sets of push blocks 10 push the slider 8 so that the snap-fit block 9 is engaged in the slot 7. At this time, the multiple sets of limiting blocks 15 are in the unlocking hole 17. Rotate the rotating sleeve 14 clockwise so that the multiple sets of slide rods 13 slide into the limiting hole 16. The multiple sets of limiting blocks 15 abut against the outer wall of the rotating sleeve 14 to limit the limiting sleeve 11. By operating in sequence, the filter media 4 can be quickly installed and fixed.
[0040] When the filter body 4 needs to be disassembled, the rotating sleeve 14 is rotated counterclockwise so that multiple sets of limiting blocks 15 slide along the limiting hole 16 into the unlocking hole 17, thereby releasing the multiple sets of limiting blocks 15 from contact with the outer wall of the rotating sleeve 14. Multiple sets of tension springs 26 pull the connecting sleeve 12 and the limiting sleeve 11, and the multiple sets of limiting sleeves 11 release the contact with the multiple sets of push blocks 10. Multiple sets of push springs 20 reset and push the push blocks 10 to slide along the slide groove 19. Multiple sets of push blocks 10 pull the locking block 9 through the slider 8 to disengage it from the locking groove 7, thereby releasing the locking of the locking rod 6. Multiple sets of compression springs 25 reset and push the top block 24. The top block 24 pushes the fixing sleeve 5, thereby separating the locking rod 6 from the fixing sleeve 5, releasing the top cover 2 from fixing the filter body 4, and then the filter body 4 can be disassembled.
