Description

Technical Field

[0001] This utility model relates to the field of pipeline filter technology, specifically a dual-cylinder filter for hydraulic lubrication equipment. Background Technology

[0002] Hydraulic lubrication systems are widely used in various mechanical equipment, such as industrial equipment, construction machinery, ships, aerospace and other high-precision equipment. During operation, these systems need to ensure the cleanliness of the hydraulic oil to avoid impurities causing wear or failure of system components. Therefore, hydraulic lubrication systems are usually equipped with filtration devices to remove solid particles, metal shavings, dust and other contaminants from the oil, ensuring the long-term stable operation of the hydraulic system.

[0003] Existing technologies disclose several utility model patents in the field of pipeline filter processing. Among them, utility model patent application number CN 206560713 U discloses a design including two L-shaped bases, a two-position six-way valve body, two filter cartridges, and filter elements inside the filter cartridges. A reversing shaft runs from top to bottom through the center of the two-position six-way valve body. Around the reversing shaft are a first L-shaped ball and a second L-shaped ball, positioned one above the other and oriented in the same direction. The first and second L-shaped balls rotate with the rotation of the reversing shaft, and the first L-shaped ball communicates with either filter cartridge. A connecting cylinder is located below the filter cartridge. One end of the connecting cylinder is connected to the second L-shaped ball, and the other end has a connecting retainer ring. The connecting retainer ring is threadedly connected to the filter cartridge, and a sealing ring is provided at the connection between the connecting retainer ring and the filter cartridge. The cylinder cover is threadedly connected to the filter cartridge. This utility model has the advantages of easy disassembly, convenient replacement and maintenance, time and labor saving, easy reversing, ensuring sealing, and preventing oil leakage from left to right.

[0004] However, the above method still has the following drawbacks in actual use: although it can achieve the function of easy disassembly, frequent disassembly and installation can easily lead to wear of the threads, thereby affecting the sealing and stability of the filter cartridge and connecting ring after connection. Moreover, the threaded connection is prone to leakage after long-term use, which reduces the applicability of the dual-cylinder filter. Utility Model Content

[0005] The purpose of this invention is to provide a dual-cylinder filter for hydraulic lubrication equipment to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dual-cylinder filter for hydraulic lubrication equipment, comprising a base, a valve body fixedly connected to the top of the base, two branch pipes fixedly connected to the outer surface of the valve body, a connecting ring fixedly connected to the top of the branch pipes, a filter cylinder snapped into the connecting ring, a collar snapped into the filter cylinder, a snap-fit ​​structure connected below the collar, the snap-fit ​​structure connected to the connecting ring, a sliding groove provided inside the filter cylinder, a connecting structure connected above the collar, the connecting structure connected to the filter cylinder, the snap-fit ​​structure comprising a rotating ring, a retaining ring, a column and a mounting block, a retaining plate fixedly connected below the rotating ring, a sealing ring fixedly connected below the retaining ring, a bolt provided inside the mounting block, and the mounting block threadedly connected to the retaining plate by the bolt.

[0007] As a further preferred embodiment of this technical solution, the front of the base is provided with a connecting tube, and the collar is engaged in the sliding groove.

[0008] As a further preferred embodiment of this technical solution, the retaining ring is fixedly connected to the outer surface of the filter cylinder, the sealing ring is snapped into the connecting ring, and the rotating ring is rotatably connected to the lower part of the collar.

[0009] As a further preferred embodiment of this technical solution, the column is fixedly connected above the connecting ring, the clamping plate is clamped inside the column, and the clamping ring overlaps above the connecting ring.

[0010] As a further preferred embodiment of this technical solution, the column is snapped into the retaining ring, the retaining plate overlaps with the retaining ring, and the mounting block is fixedly connected to the outer surface of the retaining ring.

[0011] As a further preferred embodiment of this technical solution, the connecting structure includes a connecting rod, the bottom end of which is fixedly connected to the top of the collar, and an auxiliary plate is fixedly connected to the top end of the connecting rod.

[0012] As a further preferred embodiment of this technical solution, the auxiliary plate overlaps the filter cylinder, and the auxiliary plate is provided with bolt two, which connects the auxiliary plate to the filter cylinder by bolt two.

[0013] This utility model provides a dual-cylinder filter for hydraulic lubrication equipment, which has the following beneficial effects:

[0014] (1) This utility model sets up a connecting ring, a snap-fit ​​structure and a sleeve ring, and snaps the filter cylinder into the connecting ring through the snap-fit ​​ring and the sealing ring. When the filter cylinder is fully attached to the connecting ring, it drives the rotating ring to rotate. The rotating ring will rotate on its own inside the sleeve ring. After the snap-fit ​​plate rotates with the rotating ring, it will snap into the column. Then the rotating ring is threadedly connected to the mounting block through bolt one. The double-cylinder filter enables the filter cylinder and the connecting ring to be quickly assembled through the cooperation between the column, the snap-fit ​​plate and the bolt one. The connection between the connecting ring and the filter cylinder is not threaded, which avoids the leakage caused by the threads being damaged due to long-term disassembly of the connecting ring and the filter cylinder. It also ensures the applicability and stability of the double-cylinder filter.

[0015] (2) By setting a connection structure and a sliding groove, the collar is snapped onto the outer surface of the filter cylinder through the sliding groove. When the collar is attached to the bottom of the sliding groove, the auxiliary plate will also overlap the top of the filter cylinder. Then the auxiliary plate is threadedly connected to the filter cylinder by bolt two, which can limit the position of the collar and the filter cylinder. It is convenient to repair or replace the components below the collar in the future, thus ensuring the flexibility of the dual-cylinder filter. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 1 and Figure 4As shown in this embodiment, a dual-cylinder filter for hydraulic lubrication equipment includes a base 1, a valve body 2 fixedly connected to the top of the base 1, two branch pipes 3 fixedly connected to the outer surface of the valve body 2, a connecting ring 4 fixedly connected to the top of the branch pipes 3, a filter cylinder 5 snapped into the connecting ring 4, a collar 8 snapped into the filter cylinder 5, a snap-fit ​​structure 6 connected below the collar 8, the snap-fit ​​structure 6 connected to the connecting ring 4, a sliding groove 9 opened inside the filter cylinder 5, a connecting structure 7 connected above the collar 8, the connecting structure 7 connected to the filter cylinder 5, the snap-fit ​​structure 6 includes a rotating ring 601, a retaining ring 602, a column 603 and a mounting block 606, a retaining plate 605 fixedly connected below the rotating ring 601, a sealing ring 604 fixedly connected below the retaining ring 602, a bolt 607 provided inside the mounting block 606, and the mounting block 606 threadedly connected to the retaining plate 605 by the bolt 607.

[0023] like Figure 1 and Figure 3 As shown, the front of the base 1 is provided with a connecting pipe 10, the collar 8 is snapped into the sliding groove 9, the retaining ring 602 is fixedly connected to the outer surface of the filter cylinder 5, the sealing ring 604 is snapped into the connecting ring 4, the rotating ring 601 is rotatably connected to the lower part of the collar 8, the column 603 is fixedly connected to the upper part of the connecting ring 4, the retaining plate 605 is snapped into the column 603, the retaining ring 602 overlaps the upper part of the connecting ring 4, the column 603 is snapped into the retaining ring 602, the retaining plate 605 overlaps with the retaining ring 602, and the mounting block 606 is fixedly connected to the outer surface of the collar 8.

[0024] By setting the sealing ring 604 and the retaining plate 605, when the filter cartridge 5 is engaged with the connecting ring 4, the retaining ring 602 overlaps above the connecting ring 4, and the sealing ring 604 will be engaged inside the connecting ring 4. Since the sealing ring 604 is wrapped around the surface of the filter cartridge 5, the sealing performance of the connecting ring 4 and the filter cartridge 5 after they are fixed is improved, avoiding leakage between the connecting ring 4 and the filter cartridge 5 during operation, and also playing a certain auxiliary role in fixing the connecting ring 4 and the filter cartridge 5.

[0025] like Figure 4 As shown, the connecting structure 7 includes a connecting rod 701. The bottom end of the connecting rod 701 is fixedly connected to the top of the collar 8. An auxiliary plate 702 is fixedly connected to the top of the connecting rod 701. The auxiliary plate 702 overlaps the top of the filter cylinder 5. A bolt 703 is provided inside the auxiliary plate 702. The auxiliary plate 702 is threadedly connected to the filter cylinder 5 through the bolt 703.

[0026] By setting the slide groove 9, the collar 8 is snapped onto the outer surface of the filter cylinder 5 through the slide groove 9. When the collar 8 is in contact with the bottom of the slide groove 9, the connecting rod 701 will also intersect with the slide groove 9, so that the slide groove 9 plays a certain guiding role in fixing the collar 8, avoiding the phenomenon of the collar 8 hitting the surface of the filter cylinder 5 when moving, and ensuring the accuracy of the position of the collar 8 after it is fixed.

[0027] This utility model provides a dual-cylinder filter for hydraulic lubrication equipment, and its working principle is as follows:

[0028] Before use, the double-cylinder filter can be secured to the outer surface of the filter cylinder 5 via the sliding groove 9. When the collar 8 is in contact with the bottom of the sliding groove 9, the auxiliary plate 702 will also overlap the top of the filter cylinder 5. Then, the auxiliary plate 702 is threadedly connected to the filter cylinder 5 via bolt 703. The filter cylinder 5 is then secured to the connecting ring 4 via the retaining ring 602 and the sealing ring 604. When the filter cylinder 5 and the connecting ring 4 are fully in contact, the rotating ring 601 will rotate. The rotating ring 601 will rotate within the collar 8. After the retaining plate 605 rotates with the rotating ring 601, it will be secured to the column 603. Then, the rotating ring 601 is threadedly connected to the mounting block 606 via bolt 607, so that the filter cylinder 5 and the connecting ring 4 can be fixed. It can then be connected to the lubrication equipment via the connecting pipe 10. The filter screens inside the two filter cylinders 5 will then perform filtration.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
