Description

Technical Field

[0001] This utility model relates to the field of filter element disassembly technology, specifically to an offline filter element replacement fixture. Background Technology

[0002] Oil filters are the core filtration components in a lubrication system. Their function is to intercept and remove impurities such as metal shavings, carbon deposits, gum, and external dust generated inside the equipment during the oil circulation process through internal filter paper or synthetic fiber media.

[0003] Some oil filters are installed at the bottom of the equipment. When these oil filters are disassembled, a certain amount of oil often remains at the connection between the interface and the filter housing. This residual oil can leak during disassembly. The leaked oil will flow everywhere and eventually scatter in various corners of the ground, causing oil stains all over the ground and polluting the surrounding environment.

[0004] For example, in the prior art, the authorized announcement number CN221664783U discloses an oil filter assembly, which includes a housing, a diversion filter element, a central tube, an upper end cover and a lower end cover, and also includes a main filter element, which is fixedly installed between the upper end cover and the lower end cover by an adhesive.

[0005] The aforementioned oil filter element is primarily installed and secured to equipment via a threaded interface designed on its housing. In actual operation, when the filter element needs to be removed from the equipment, the oil remaining at the interface will leak out due to the loss of a sealed environment. This leaked oil often drips directly onto the ground, causing pollution, affecting environmental hygiene, potentially posing safety hazards, or increasing cleaning workload. Summary of the Invention

[0006] The purpose of this invention is to provide an offline filter replacement fixture to solve the problems in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an offline filter element replacement fixture, including a filter element housing, a threaded interface on the filter element housing, an oil receiving cylinder sleeved on the filter element housing, a rubber pad fixedly installed at the upper end of the oil receiving cylinder, a disassembly mechanism installed inside the oil receiving cylinder, the disassembly mechanism including a sliding sleeve fixedly installed at the middle position of the bottom of the oil receiving cylinder, a drive rod slidably installed inside the sliding sleeve, a square plug fixedly installed at the upper end of the drive rod, a sleeve connected to the square plug, a handle connected to the lower end of the drive rod, and a limiting mechanism provided on the square plug.

[0008] Preferably, the bottom of the oil receiving cylinder is provided with an oil drain port, and the lower end of the drive rod is provided with a connection hole.

[0009] Preferably, the bottom of the sleeve has a square groove, and the square plug is embedded inside the sleeve through the square groove.

[0010] Preferably, the drive rod is slidably installed in the oil receiving cylinder body through a sliding sleeve, the handle is connected to the lower end of the drive rod through a connecting hole, the drive rod is connected to the bottom of the sleeve through a square plug, a positioning groove is provided at the upper end of the oil receiving cylinder body, and the rubber pad is installed at the upper end of the oil receiving cylinder body through the positioning groove.

[0011] Preferably, the limiting mechanism includes a movable slide groove formed on the square plug and a positioning slide groove formed on the drive rod. A return spring is provided in the movable slide groove, and a limiting post is slidably installed in the movable slide groove. A steel cable is fixedly connected between the limiting posts. A crossbar is slidably installed in the positioning slide groove, and a linkage rod is fixedly installed at the middle position of the crossbar, with the upper end of the linkage rod fixed at the middle position of the steel cable.

[0012] Preferably, a slot is provided on the sleeve at the upper end of the drive rod, and the limiting post is embedded in the sleeve through the slot.

[0013] Preferably, the crossbar is slidably mounted on the drive rod via a positioning groove.

[0014] Preferably, the limiting post is slidably mounted on the square plug via a movable groove, one end of the reset spring is connected to the limiting post, and the other end of the reset spring is connected to the movable groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. In this application, the user can hold the oil receiving cylinder with one hand and place it on the filter element housing, while using the other hand to push the drive rod upward. After the drive rod moves upward, it will drive the sleeve upward until the sleeve connects with the bottom of the filter element housing. After the sleeve connects to the bottom of the filter element housing, the handle can be rotated. When the handle is rotated, the drive rod will drive the sleeve to rotate, and the rotation of the sleeve will in turn drive the rotation of the filter element housing, thereby unscrewing the filter element off the equipment.

[0016] 2. In this application, when the filter element is unscrewed from the equipment, the oil receiving cylinder can catch leaked oil, preventing it from spilling onto the ground. Furthermore, the oil collected in the oil receiving cylinder can be discharged into a storage tank via an oil pipe, enabling the recycling of leaked oil. When the crossbar is pushed downwards, it drives the linkage rod to move downwards. During this downward movement, the linkage rod applies a downward pulling force to the steel cable, causing the limiting post to move into the movable slide groove and disengage from the slot on the sleeve. After the limiting post disengages from the sleeve slot, the sleeve can be removed from the square plug, facilitating the replacement of different sleeve models to accommodate different sizes of filter elements.

[0019] 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.

[0020] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for an offline filter element replacement fixture, including a filter element housing 4, a threaded interface 3 on the filter element housing 4, an oil receiving cylinder 1 fitted on the filter element housing 4, a rubber pad 2 fixedly installed at the upper end of the oil receiving cylinder 1, a disassembly mechanism 5 installed inside the oil receiving cylinder 1, and a limiting mechanism 6 on the square plug 501. Through the cooperation of the disassembly mechanism 5 and the limiting mechanism 6, different types of filter elements can be disassembled conveniently and quickly, and leaked oil can be prevented from spilling on the ground.

[0021] Example 1: As Figure 2 and Figure 3 As shown, the disassembly mechanism 5 includes a sliding sleeve 502 fixedly installed at the middle position of the bottom of the oil receiving cylinder 1. A drive rod 505 is slidably installed inside the sliding sleeve 502. A square plug 501 is fixedly installed at the upper end of the drive rod 505. A sleeve 504 is connected to the square plug 501. A handle 506 is connected to the lower end of the drive rod 505. An oil drain port 503 is opened at the bottom of the oil receiving cylinder 1. A connection hole 507 is opened at the lower end of the drive rod 505. A square groove is opened at the bottom of the sleeve 504. The square plug 501 is embedded into the sleeve 504 through the square groove.

[0022] Specifically, the user can hold the oil receiving cylinder 1 with one hand and place it onto the filter element housing 4, while simultaneously pushing the drive rod 505 upwards with the other hand. As the drive rod 505 rises, it will also lift the sleeve 504 until the sleeve 504 is securely connected to the bottom of the filter element housing 4. After connection, the user can rotate the handle 506. This will cause the drive rod 505 to rotate the sleeve 504, which in turn will rotate the filter element housing 4, ultimately unscrewing the filter element from the equipment. During the unscrewing process, the oil receiving cylinder 1 will catch any leaked oil, preventing it from spilling onto the ground. Furthermore, the oil collected in the oil receiving cylinder 1 can be discharged into a storage tank via an oil pipe for easy recovery of leaked oil.

[0023] Example 2: Figure 2 and Figure 4 As shown, the limiting mechanism 6 includes a movable slide groove 602 on the square plug 501 and a positioning slide groove 607 on the drive rod 505. A return spring 604 is provided in the movable slide groove 602. A limiting post 601 is slidably installed in the movable slide groove 602. A steel cable 603 is fixedly connected between the limiting posts 601. A crossbar 606 is slidably installed in the positioning slide groove 607. A linkage rod 605 is fixedly installed in the middle of the crossbar 606, and the upper end of the linkage rod 605 is fixed in the middle of the steel cable 603. A slot is provided on the sleeve 504 at the upper end of the drive rod 505. The limiting post 601 is embedded in the sleeve 504 through the slot. The crossbar 606 is slidably installed on the drive rod 505 through the positioning slide groove 607.

[0024] Specifically, when the crossbar 606 is moved downwards, it will cause the linkage rod 605 to move downwards. During the downward movement of the linkage rod 605, the steel cable 603 will be pulled down, thereby causing the limiting post 601 to move into the movable slide groove 602 and disengage from the slot on the sleeve 504. Once the limiting post 601 disengages from the slot on the sleeve 504, the sleeve 504 can be removed from the square plug 501, facilitating the replacement of different models of sleeves 504 to meet the disassembly requirements of different sized filter elements.

[0025] Working Principle: First, connect the oil pipe on the storage tank to the oil drain port 503. Then, hold the oil receiving cylinder 1 with one hand and place it onto the filter element housing 4. With the other hand, push the drive rod 505 upwards. The drive rod 505 will then move the sleeve 504 upwards, connecting it to the bottom of the filter element housing 4. After the sleeve 504 is connected, rotate the handle 506. Rotating the handle 506 will cause the drive rod 505 to rotate, which in turn will rotate the filter element housing 4, thus unscrewing the filter element from the equipment. When the filter element is unscrewed, the oil receiving cylinder 1 will catch any leaked oil, preventing it from spilling onto the ground. The oil collected by the oil receiving cylinder 1 can be discharged into the storage tank through the oil pipe for oil recovery. When the horizontal bar 606 is pushed down, it will drive the linkage rod 605 to move downward. When the linkage rod 605 moves downward, it will pull down the steel cable 603, causing the limiting post 601 to move into the movable slide groove 602 and disengage from the slot on the sleeve 504. After the limiting post 601 disengages from the slot on the sleeve 504, the sleeve 504 can be removed from the square plug 501, making it convenient to replace different models of sleeves 504 so that different sizes of filter elements can be disassembled.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
