Description

Technical Field

[0001] This utility model belongs to the field of oil filter technology, specifically an oil filter that can be quickly installed and removed. Background Technology

[0002] Oil filters are components that filter oil. They use filter media such as filter paper and metal mesh to intercept impurities such as dust, metal particles, and carbon deposits in the oil, ensuring that the oil entering the engine, hydraulic system, and other equipment is clean. Different equipment uses different oil filters, but their function is the same: to protect the normal operation of the equipment and extend the service life of the equipment and the oil.

[0003] Currently, after prolonged use, many impurities remain in the filter holes on the oil filter body. These impurities clog the filter holes, affecting the filtration of oil. Not only does the filtration speed slow down, but the filtration effect is also poor. Therefore, manual cleaning by staff is required, which is time-consuming and labor-intensive. At the same time, the installation and disassembly of existing oil filters are cumbersome, increasing the workload of the staff. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides an oil filter element that can be quickly installed and removed. This solves the problem that after prolonged use, many impurities remain in the filter holes on the oil filter element body, which can clog the filter holes and affect the filtration of oil. This not only slows down the filtration speed but also reduces the filtration effect. Therefore, manual cleaning by staff is required, which is time-consuming and labor-intensive. At the same time, the installation and disassembly of existing oil filter elements are cumbersome, increasing the workload of the staff.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-installing and detachable oil filter element, comprising an oil pipe, a pipe head fixedly installed at the end of the oil pipe, an oil filter element body disposed inside the oil pipe, a threaded end of the oil filter element body, a plurality of filter holes formed on the oil filter element body, a scraper ring slidably installed inside the oil filter element body, the scraper ring being tightly fitted against the inner wall of the oil filter element body, an installation ring disposed inside the oil filter element body, a plurality of corresponding positioning grooves formed on the installation ring and the scraper ring, the scraper ring being installed at the bottom of the installation ring, a fixing bolt being installed in the positioning groove, a plurality of connecting rods being fixedly installed on the installation ring, and a handle being fixedly installed at the end of the connecting rod.

[0006] As a further embodiment of this utility model: a plurality of limiting grooves are provided on the tube head, and a reset spring is installed in the limiting groove.

[0007] As a further embodiment of this utility model: a limiting block is connected to the reset spring, the limiting block is slidably installed in the limiting groove, and a fixing ring is fixedly installed at the end of the oil filter element body.

[0008] As a further embodiment of this utility model: the fixing ring is provided with a plurality of slots, the slots corresponding to the limiting slots, and the limiting block is slidably engaged in the limiting slot.

[0009] As a further embodiment of this utility model: a protective cover is threaded onto the oil filter element body, and an injection port is provided on the protective cover.

[0010] As a further embodiment of this utility model: the handle is provided with anti-slip texture, filter paper is installed at the bottom of the fixing ring, the oil filter element body is installed inside the filter paper, and a gap is left between the filter paper and the oil pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This quick-install and removable oil filter element, with its protective cover, handle, mounting ring, and connecting rods, allows for easy cleaning of the filter holes. When cleaning is required, the operator first separates the oil filter element from the oil pipe, then rotates the protective cover until it separates from the filter element. Holding the handle and pulling it with the aid of the anti-slip texture, the operator moves several connecting rods. Since the connecting rods are fixed to the mounting ring, their movement causes the mounting ring to move as well. Simultaneously, because the scraper ring is fixed to the bottom of the mounting ring with bolts, its movement causes the scraper ring to move along the inner wall of the oil filter element. Because the scraper ring is close to the inner wall of the oil filter element, its movement cleans residual oil and impurities from the filter holes. Repeatedly pulling the handle continues until cleaning is complete, eliminating the need for manual cleaning of each filter hole, saving time and effort.

[0013] 2. This quick-installation and removable oil filter element features a protective cover, a retaining ring, a limiting block, and a slot. During operation, the operator pulls the protective cover. Since the protective cover is threaded onto the oil filter element body, which is fixedly mounted on the retaining ring, the protective cover moves the retaining ring. This movement of the retaining ring compresses the limiting block in the slot, causing it to move within the slot until it completely separates from the slot. For installation, simply align the elements and press down on the protective cover. This design solves the problem of cumbersome oil filter element installation and reduces workload.

Detailed Implementation

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a quick-installing and detachable oil filter element, including an oil pipe 1, a pipe head 2 fixedly installed at the end of the oil pipe 1, a plurality of limiting grooves 6 opened on the pipe head 2, a return spring 10 installed in the limiting groove 6, a limiting block 11 connected to the return spring 10, the limiting block 11 slidably installed in the limiting groove 6, and a fixing ring 3 fixedly installed at the end of the oil filter element body 8. Because of the installation of the return spring 10, when the fixing ring 3 squeezes the locking block during the installation of the oil filter element body 8, the limiting block 11 will move in the limiting groove 6, thereby compressing the return spring 10. When the fixing ring 3 moves to the appropriate position, the elastic force generated by the return spring 10 will drive the limiting block 11 to reset, thereby locking the limiting block 11 into the locking groove 12, solving the problem of complicated oil filter element installation and reducing the workload.

[0021] The fixed ring 3 has several slots 12, which correspond to the limiting slots 6. The limiting block 11 is slidably engaged in the limiting slots 6.

[0022] The oil pipe 1 is equipped with an oil filter element body 8. The oil filter element body 8 is connected to a protective cover 4 by a thread 9. The protective cover 4 has a filling port 5. Because the thread 9 is connected to the protective cover 4, the protective cover 4 can prevent external dust, impurities, etc. from entering the oil filter element, avoid the filter element from being contaminated, prevent oil leakage, and reduce operating costs.

[0023] The oil filter element body 8 has a thread 9 at its end and several filter holes 13 on it. A scraper ring 20 is slidably installed inside the oil filter element body 8, and the scraper ring 20 is in close contact with the inner wall of the oil filter element body 8. An installation ring 17 is provided inside the oil filter element body 8. Several corresponding positioning grooves 18 are provided on the installation ring 17 and the scraper ring 20. The scraper ring 20 is installed at the bottom of the installation ring 17. Fixing bolts 19 are installed in the positioning grooves 18. Several connecting rods 16 are fixedly installed on the installation ring 17. A handle 14 is fixedly installed at the end of the filter element. Because of the handle 14, pulling the handle 14 will move the mounting ring 17. The movement of the mounting ring 17 will move the scraper ring 20 along the inner wall of the oil filter element body 8. Since the scraper ring 20 is close to the inner wall of the oil filter element body 8, the scraper ring 20 will clean the residual oil stains on the inner wall of the oil filter element body 8 and the impurities in the filter holes 13 when it moves. Pull the handle 14 repeatedly until the cleaning is completed. There is no need for the staff to manually clean each filter hole 13, which saves time and effort.

[0024] The handle 14 has anti-slip texture 15, and the bottom of the fixing ring 3 is fitted with filter paper 7. The oil filter element body 8 is installed inside the filter paper 7. There is a gap between the filter paper 7 and the oil pipe 1. Because the filter paper 7 is installed, the oil filtered by the oil filter element body 8 can be filtered again through the filter paper 7, which can adsorb the finer impurities and ensure the purity of the oil.

[0025] The working principle of this utility model is as follows: During operation, the operator pulls the protective cover 4. Since the protective cover 4 is threaded 9 onto the oil filter element body 8, and the oil filter element body 8 is fixedly mounted on the fixing ring 3, the protective cover 4 will drive the fixing ring 3 to move. The movement of the fixing ring 3 will squeeze the limiting block 11 in the slot 12. The pressure generated by the squeezing will cause the limiting block 11 to move within the limiting groove 6 until the limiting block 11 is completely separated from the slot 12. After separating the oil filter element body 8 from the oil pipe 1, rotate the protective cover 4 until the protective cover 4 is separated from the oil filter element body 8. After grasping the handle 14, the anti-slip texture 15 will be used to assist the operation. Pull down the handle 14. The movement of the handle 14 will move several connecting rods 16 connected to it. Since the connecting rods 16 are fixedly installed on the mounting ring 17, the movement of the connecting rods 16 will cause the mounting ring 17 to move. At the same time, since the scraper ring 20 is installed at the bottom of the mounting ring 17 by the fixing bolt 19, the movement of the mounting ring 17 will cause the scraper ring 20 to move along the inner wall of the oil filter element body 8. Since the scraper ring 20 is close to the inner wall of the oil filter element body 8, the movement of the scraper ring 20 will clean the residual oil stains on the inner wall of the oil filter element body 8 and the impurities in the filter holes 13. Pull the handle 14 repeatedly until the cleaning is completed.
