Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment filter technology, specifically a refrigeration equipment filter that can be quickly disassembled. Background Technology

[0002] During the operation of refrigeration equipment, the filter, as one of the core components, plays an important role in filtering impurities, moisture and other harmful substances in the refrigerant. Its performance directly affects the operating efficiency, service life and refrigeration effect of the refrigeration equipment. In order to ensure the continuous and stable operation of the filter, it is necessary to disassemble, maintain, clean or replace the filter element regularly. Therefore, the ease of disassembly and assembly of the filter has become a key consideration in the maintenance of refrigeration equipment.

[0003] Most mainstream refrigeration equipment filters on the market currently use flange connections. Specifically, multiple connection holes are evenly opened on the circumference of the flange edge corresponding to the filter body and the refrigeration system pipeline. During assembly, bolts are inserted into the connection holes of the flanges on both sides in sequence, and nuts are tightened to achieve a fixed seal between the two.

[0004] While this connection structure can meet the basic requirements of refrigeration systems for sealing performance and connection stability, in actual disassembly and maintenance, multiple bolts are required to fix the flange edge. During disassembly, tools are needed to loosen and remove all bolts one by one, and during installation, all bolts need to be aligned with the holes and tightened one by one. This not only involves cumbersome operation steps but also consumes a lot of time. Especially in scenarios where the installation space of some refrigeration equipment is narrow, the difficulty of bolt disassembly and assembly is further increased. This not only prolongs the downtime for equipment maintenance but may also lead to bolts not being installed properly due to limited operating space, thereby affecting the sealing performance of the flange connection, increasing the risk of refrigerant leakage, and creating hidden dangers for the normal operation of refrigeration equipment.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0006] The purpose of this invention is to provide a quick-disassembly filter for refrigeration equipment to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a quick-disassembly refrigeration equipment filter, including an internal threaded ring, a limiting plate, and a connecting plate. A spiral strip is fixedly installed on the side wall of the internal threaded ring, and a threaded tube is threadedly connected to the center of the inner wall of the internal threaded ring. Six abutments are engaged with the outer wall of the spiral strip, and the angle between the six abutments is 60 degrees. The limiting plate is rotatably installed on the side wall of the internal threaded ring. Six guide grooves are opened on the inner wall of the limiting plate near the internal threaded ring, and a abutment is slidably connected to the inner wall of each of the six guide grooves. A through hole is provided at the center of the inner wall of the limiting plate. The inner wall of the through hole is fixedly connected to the outer wall of the threaded pipe. Six positioning grooves are provided on the side of the connecting plate near the limiting plate. A locking block is fixedly installed on the inner wall of each of the six positioning grooves. An inclined groove is provided on the inner wall of each locking block. A sealing ring is fixedly installed at the center of the connecting plate. The sealing ring can abut against the end of the threaded pipe.

[0008] Furthermore, the inner wall of the guide groove is slidably connected to the outer wall of the rack, and the guide groove is used to guide the sliding of the rack. The inner wall of the through hole is fixedly connected to the outer wall of the threaded pipe, and the through hole is welded to the threaded pipe.

[0009] Furthermore, the locking block is fixedly installed on the inner wall of the positioning groove, the inclined groove on the locking block cooperates with the inclined block on the abutment block, the sealing ring is fixedly installed at the center of the connecting plate, and the sealing ring can abut against the end of the threaded pipe.

[0010] Furthermore, the abutment includes a rack that meshes with the auger, the inner wall of the rack has a groove, and an inclined block is fixedly installed on the side end of the rack, the inner wall of the inclined block abuts against the groove.

[0011] Furthermore, the positioning groove on the connecting plate corresponds to the abutment block, and the positioning groove is used to position the abutment block.

[0012] Compared with the prior art, the beneficial effects of this utility model are: Through the threaded connection between the internal threaded ring and the threaded pipe, and the meshing transmission between the spiral strip and the abutment rack, only one operation of rotating the internal threaded ring is needed to drive the six abutments, which are evenly distributed at 60 degrees, to slide synchronously along the guide groove of the limiting plate. When disassembling, rotating the internal threaded ring in the opposite direction can release the lock, and the connecting plate can be pulled out directly to complete the separation. No tools are needed to disassemble and install the bolts throughout the process, reducing the time spent on disassembly and assembly operations and effectively shortening the downtime of refrigeration equipment due to filter maintenance. The alignment design of the connecting plate positioning groove and the anti-block inclined block eliminates the need to repeatedly adjust the positional relationship between the bolts and the holes. The operation of rotating the internal thread ring does not require a large operating space. The synchronous movement of the anti-block also avoids the inconvenience of operating the bolts one by one in a narrow space. Even in scenarios where the installation space of refrigeration equipment is limited, the filter can be easily installed and removed. Attached Figure Description

[0015] 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.

[0016] Please see Figures 1-6This utility model provides a technical solution: a quick-disassembly refrigeration equipment filter, including an internal threaded ring 1, a limiting disc 2, and a connecting disc 3. A spiral strip 11 is fixedly installed on the side wall of the internal threaded ring 1. A threaded tube 5 is threadedly connected to the center of the inner wall of the internal threaded ring 1. The threaded connection between the internal threaded ring 1 and the threaded tube 5 serves as the power input end. Six abutment blocks 4 are meshed and connected to the outer wall of the spiral strip 11. The meshing transmission between the spiral strip 11 and the abutment blocks 4 serves as the power transmission end. The angle between the six abutment blocks 4 is 60 degrees. The six abutment blocks 4 are evenly distributed at 60 degrees and move synchronously without individual adjustment. The limiting disc 2 is rotatably installed on the side wall of the internal threaded ring 1. Six guide grooves 21 are opened on the inner wall of the limiting disc 2 near the internal threaded ring 1. The guide grooves 21 of the limiting disc 2 serve as the motion constraint ends for the abutment blocks 4. The three components work together to convert the rotational motion into synchronous radial sliding of the six abutment blocks 4, replacing the linear operation of tightening and loosening bolts one by one in the traditional method. The operation requires no disassembly of multiple bolts; locking and unlocking can be completed simply by rotating the internal threaded ring 1. It requires minimal operating space and is suitable for environments with dense piping and limited space for refrigeration equipment. Each of the six guide grooves 21 has a corresponding sliding connection to a stop block 4. A through hole 22 is located at the center of the inner wall of the limiting plate 2, and the inner wall of the through hole 22 is fixedly connected to the outer wall of the threaded pipe 5. Six positioning grooves 31 are located on the side of the connecting plate 3 near the limiting plate 2. During installation, the alignment design of the positioning grooves 31 and the stop blocks 4 replaces the traditional bolt holes for precise alignment, significantly reducing operational difficulty and shortening maintenance time. Each of the six positioning grooves 31 has a fixedly installed locking block 32. The combination design of the positioning grooves 31 and locking blocks 32 allows for quick docking with the stop blocks 4. An inclined groove 33 is located on the inner wall of the locking block 32. A sealing ring 34 is fixedly installed at the center of the connecting plate 3, and the sealing ring 34 can abut against the end of the threaded pipe 5.

[0017] Please see Figures 1-6 This utility model provides a technical solution: a quick-disassembly refrigeration equipment filter, including a stop block 4 including a rack 41 that meshes with a spiral strip 11. The inner wall of the rack 41 is provided with a sliding groove 42. An inclined block 43 is fixedly installed on the side end of the rack 41. The inclined block 43 abuts against the inclined groove 33 of the locking block 32, converting the radial sliding of the stop block 4 into the axial tension of the connecting plate 3, realizing the direction conversion of the force, and providing a key transmission structure for the quick locking of the connecting plate 3 and the limiting plate 2. The inner wall of the inclined block 43 abuts against the inclined groove 33.

[0018] Please see Figures 1-6This utility model provides a technical solution: a quick-disassembly refrigeration equipment filter, including a guide groove 21 whose inner wall is slidably connected to the outer wall of a rack 41, and the guide groove 21 is used to guide the sliding of the rack 41. The guiding function of the guide groove 21 can prevent the abutment 4 from deviating or tilting during radial sliding, ensuring the synchronicity and consistency of the movement of the six abutment 4, while reducing the lateral force at the meshing point of the rack 41 and the spiral strip 11, reducing the wear of the meshing tooth surface, and extending the service life of the abutment 4 and the spiral strip 11.

[0019] Please see Figures 1-6 This utility model provides a technical solution: a quick-disassembly refrigeration equipment filter, including a positioning groove 31 on the connecting plate 3 corresponding to the abutment block 4. The positioning groove 31 is used to position the abutment block 4. The positioning groove 31 wraps around the abutment block 4, which can limit the radial displacement of the connecting plate 3, avoid the connecting plate 3 from shifting due to vibration during the operation of the refrigeration equipment, and ensure connection stability. The locking block 32 is fixedly installed on the inner wall of the positioning groove 31. The inclined groove 33 on the locking block 32 cooperates with the inclined block 43 on the abutment block 4. The cooperation angle of the inclined groove 33 and the inclined block 43 is the same, ensuring that the radial sliding of the abutment block 4 can be efficiently converted into the axial tension of the connecting plate 3.

[0020] Please see Figures 1-6 This utility model provides a technical solution: a quick-disassembly refrigeration equipment filter, including a sealing ring 34 fixedly installed at the center of the connecting plate 3, the sealing ring 34 and the threaded pipe 5 abutting seal cooperation, the axial tension of the connecting plate 3 forms a compression seal, the sealing effect is enhanced as the tension increases, and the sealing ring 34 can abut against the end of the threaded pipe 5.

[0021] Working principle: During installation, first align the positioning groove 31 of the connecting disc 3 on the filter with the inclined block 43 of the abutment 4 and insert it, so that the inclined block 43 is initially embedded in the inclined groove 33 of the locking block 32. At this time, the sealing ring 34 in the center of the connecting disc 3 contacts the end of the threaded pipe 5. Rotate the inner threaded ring 1, and its threaded connection with the threaded pipe 5 drives the spiral strip 11 on the side wall to rotate synchronously. The spiral strip 11 meshes with the rack 41 of the abutment 4, driving the six abutments 4 distributed at 60 degrees to move away from the center along the guide groove 21 of the limiting disc 2. When the inclined block 43 slides along the inclined groove 33, the inclined force pulls the connecting plate 3 towards the limiting plate 2, so that the sealing ring 34 and the threaded pipe 5 are tightly abutted. Continue to rotate the inner threaded ring 1 until it is locked with the threaded pipe 5 to complete the installation. When disassembling, rotate the inner threaded ring 1 in the opposite direction. The spiral strip 11 drives the abutment 4 to slide along the guide groove 21 towards the center. The inclined block 43 exits from the inclined groove 33, the locking between the connecting plate 3 and the limiting plate 2 is released, and the connecting plate 3 can be directly pulled out. The whole process does not require disassembling the bolts.

[0022] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
