Description

Technical Field

[0001] This utility model relates to the field of cartridge filter technology, specifically a stable installation structure for a cartridge filter protective mesh. Background Technology

[0002] A cartridge filter mainly consists of a connecting pipe, a cartridge body, a filter basket, a flange, a flange cover, and fasteners. The working principle of a cartridge filter is relatively simple: when fluid passes through the cartridge body, solid impurities are blocked by the filter basket and remain inside the cartridge, while clean fluid continues to flow through the filter basket. As usage time increases, impurities gradually accumulate in the filter basket, requiring regular cleaning or replacement to maintain filtration efficiency.

[0003] Chinese patent publication number CN220736796U discloses a buckle for a cylindrical filter protective mesh, relating to the field of filter protective mesh buckle connection technology. The buckle includes a filter barrel, with a connecting plate fixedly connected to one end. A fixing plate is provided on one side of the connecting plate, and an inner protective mesh is connected to one end of the fixing plate. A connecting block is fixedly connected to the inner wall of the inner protective mesh. An outer protective mesh is fixedly connected to the other side of the fixing plate away from the inner protective mesh, and a support ring is connected to the inner wall of the outer protective mesh. A buckle mechanism is provided at one end of the fixing plate, and a fixing block is provided at one end of the buckle mechanism. A locking block is fixedly connected to the surface of the fixing plate.

[0004] However, the following drawbacks still exist: When using the above-mentioned cartridge filter device, there is a potential problem with the design of the locking position: the locking rod is in the form of a round rod, and the locking groove in which it is located has a certain space gap. This gap in the design allows the locking rod to move unnecessarily in the locking groove. Once the locking rod is displaced, it may cause the protective net to shift or deform. This situation will not only affect the normal filtration effect of the filter, but may also lead to a decrease in the stability of the entire equipment.

[0005] Therefore, a stable installation structure for a cylindrical filter protective mesh is proposed. Utility Model Content

Detailed Implementation

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

[0026] Example 1:

[0027] Based on the existing problem that displacement of the locking rod causes the protective netting to shift or deform, please refer to... Figures 1-4 This utility model provides a technical solution: a stable installation structure for a cylindrical filter protective net, including a filter body 1, a protective net frame 2 sleeved on the outside of the filter body 1, a positioning groove on the top surface of the protective net frame 2, a fixing mechanism 3 above the protective net frame 2, and a connecting mechanism 4 below the protective net frame 2.

[0028] The fixing mechanism 3 includes an engaging part and a fixing part;

[0029] The connecting mechanism 4 includes a connecting part and a positioning part.

[0030] The engaging part includes a retaining ring 31, which is fixedly sleeved on the outer side of the filter body 1. A sliding block 32 is fixedly provided on the outer side of the retaining ring 31, and three sliding blocks 32 are evenly arranged.

[0031] The top surface of the protective net frame 2 is fixedly provided with a connecting compartment 33. The connecting compartment 33 has a connecting groove inside, and three connecting grooves are evenly arranged. A locking groove is provided on the other side of the connecting groove. The connecting groove and the adjacent locking groove are interconnected. The sliding block 32 is slidably connected with the inner wall of the connecting groove and the inner wall of the locking groove. Sealing grooves are provided on the front and rear sides of the connecting compartment 33.

[0032] The fixing part includes a connecting ring 34, which is located inside the connecting chamber 33. A lifting frame 35 is fixedly installed on the side of the connecting chamber 33. Three lifting frames 35 are evenly arranged. The lifting frames 35 are located inside the adjacent connecting grooves and are slidably connected to the inner wall of the adjacent connecting grooves.

[0033] A positioning block 36 is provided below the lifting frame 35. The positioning block 36 is fixedly installed inside the adjacent connecting groove. The lower end of the lifting frame 35 passes through the positioning block 36 and is slidably connected to the inner wall of the positioning block 36. A first spring 37 is sleeved on the outer side of the lower end of the lifting frame 35. The two ends of the first spring 37 are fixedly connected to the lifting frame 35 and the positioning block 36 respectively.

[0034] Furthermore, in this embodiment, the filter body 1 is placed inside the protective mesh frame 2. When the filter body 1 moves downward, it drives the sliding block 32 to move downward. During the movement of the sliding block 32, it squeezes the lifting frame 35, causing the lifting frame 35 to move downward and the first spring 37 to contract. When the lower end of the lifting frame 35 contacts the upper end of the positioning block 36, the sliding block 32 is located at the junction of the connecting groove and the locking groove. Then, the filter body 1 is rotated, and the filter body 1 drives the fixing ring 31 and the sliding block 32 to rotate, causing the sliding block 32 to slide from the connecting groove into the locking groove. Then, the first spring 37 reaches the lifting frame 35 and returns to its original position. The lifting frame 35 moves to the junction of the connecting groove and the locking groove, restricting the sliding block 32 in the locking groove, causing the sliding block 32 to lock, thus completing the connection between the filter body 1 and the protective mesh frame 2.

[0035] Furthermore, in this embodiment, when the sliding block 32 slides into the locking groove and is restricted by the lifting frame 35, a stable mechanical lock is formed, ensuring a tight connection between the filter body 1 and the protective mesh frame 2, preventing the filter body from accidentally falling off or loosening during use. The addition of the first spring 37 not only provides the lifting frame 35 with reset power, but also plays a buffering role to a certain extent, reducing the damage to the equipment that may be caused by improper operation or external impact.

[0036] Example 2:

[0037] Please see Figures 1-4 Furthermore, based on Embodiment 1, the following is obtained: the connecting part includes a connecting frame 41, the connecting frame 41 is fixedly connected to the lower end of the connecting ring 34, two connecting frames 41 are provided at the front and rear, and the other end of the connecting frame 41 passes through the sealing groove and extends to the outside of the connecting chamber 33.

[0038] Sealing plates 42 are fixedly installed on the upper and lower surfaces of the connecting frame 41. The upper sealing plate 42 passes through the connecting chamber 33 and is slidably connected to the connecting chamber 33. The lower sealing plate 42 passes through the connecting chamber 33 and extends into the positioning groove. A limiting frame 43 is fixedly installed on the outer side of the protective net frame 2. The upper end of the limiting frame 43 passes through the connecting frame 41 and is slidably connected to the connecting frame 41. A second spring 44 is sleeved on the outer side of the upper end of the limiting frame 43. The two ends of the second spring 44 are fixedly connected to the connecting frame 41 and the limiting frame 43, respectively.

[0039] The positioning part includes a positioning ring 45, which is fixedly sleeved on the outer side of the filter body 1. A positioning seat 46 is fixedly installed on the bottom surface of the protective mesh frame 2, and the positioning ring 45 is slidably connected to the inner wall of the positioning seat 46.

[0040] Furthermore, in this embodiment, when disassembling the filter body 1 and the protective mesh frame 2, it is only necessary to press the connecting frame 41. The connecting frame 41 drives the connecting ring 34 and the lifting frame 35 to move downward, so that the junction of the connecting groove and the locking groove is exposed. Then the filter body 1 can be rotated and the filter body 1 can be taken out.

[0041] Furthermore, in this embodiment, the connection and disassembly process mainly relies on the sliding of the sliding block 32 between the connecting groove and the engaging groove, as well as the up and down movement of the lifting frame 35, so that the user can complete the installation and disassembly without using complicated tools or additional steps.

[0042] In use, the sliding block 32 on the fixed ring 31 is aligned with the connecting groove on the connecting chamber 33. Then, the filter body 1 is placed into the protective mesh frame 2. When the filter body 1 moves downward, it drives the sliding block 32 to move downward. During the movement of the sliding block 32, it squeezes the lifting frame 35, causing the lifting frame 35 to move downward and the first spring 37 to contract. When the lower end of the lifting frame 35 contacts the upper end of the positioning block 36, the filter body 1 moves to the lowest point. The positioning ring 45 at the lower end of the filter body 1 contacts the bottom end of the inner wall of the positioning seat 46. At this time, the sliding block 32 is located at the junction of the connecting groove and the engaging groove. Then, the filter body 1 is rotated. The main body 1 drives the fixed ring 31 and the sliding block 32 to rotate, causing the sliding block 32 to slide from the connecting groove into the locking groove. Then, the first spring 37 reaches the lifting frame 35 and returns to its original position. The lifting frame 35 moves to the junction of the connecting groove and the locking groove, restricting the sliding block 32 in the locking groove and locking it, thus completing the connection between the filter body 1 and the protective mesh frame 2. When disassembling the filter body 1 and the protective mesh frame 2, simply press the connecting frame 41. The connecting frame 41 drives the connecting ring 34 and the lifting frame 35 to move downward, exposing the junction of the connecting groove and the locking groove. Then, the filter body 1 can be rotated and removed.
