[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 , a filter cartridge structure, including a cylinder 1, a rubber sealing ring 14 is fixedly installed on the top of the cylinder 1, through the setting of the rubber sealing ring 14, after the sealing cover on the oil inlet of the diesel engine is tightened, the bottom of the sealing cover is abutted against the top of the rubber sealing ring 14 to ensure its sealing. The inner wall of the cylinder 1 is provided with two limiting grooves 2, and a sealing mechanism is provided between the two limiting grooves 2. The sealing mechanism includes a sliding block 3 slidably connected in the two limiting grooves 2, and a spring 4 is fixedly connected between the bottom of the two sliding blocks 3 and the inner bottom of the relative limiting grooves 2. A blocking block 5 is fixedly installed between the side walls of the two sliding blocks 3. The bottom of the filter cartridge 6 is abutted against the top of the blocking block 5. Through the setting of the mounting ring 9 and the blocking mechanism, when the filter cartridge 6 pops out, the oil inlet can be blocked to prevent foreign matter from entering the diesel engine through the oil inlet.

[0023] A mounting ring 9 is fixedly mounted on the inner wall of the cylinder 1, and two connecting grooves 13 are provided on the top of the mounting ring 9. A filter cartridge 6 is placed in the cylinder 1, and the bottom of the filter cartridge 6 abuts against the top of the blocking mechanism. A plurality of filter screens 7 are provided on the filter cartridge 6. Two connecting mechanisms are provided on the side wall of the filter cartridge 6, and both connecting mechanisms extend into the opposite connecting grooves 13 and abut against the inner bottoms thereof. The connecting mechanism comprises a connecting block 8 fixedly mounted on the side wall of the filter cartridge 6, and the connecting block 8 extends into the opposite connecting grooves 13 and abuts against the inner bottoms thereof. A connecting hole 11 is provided through the connecting block 8.

[0024] A fixing mechanism is provided in each of the two connecting grooves 13. Both fixing mechanisms penetrate the relative connecting mechanism and are slidably connected thereto. The fixing mechanism includes a threaded hole 12 opened on the bottom of the connecting groove 13. A locking bolt 10 is threadedly connected to the threaded hole 12. The locking bolt 10 penetrates the relative connecting hole 11 and is slidably connected thereto. Through the setting of the locking bolt 10, the filter cartridge 6 placed in the cylinder body 1 can be limited and fixed. Through the setting of the connecting mechanism, the fixing mechanism and the sealing mechanism, when the filter cartridge 6 needs to be taken out from the oil inlet of the diesel engine, the filter cartridge 6 can be automatically ejected, making it convenient for the operator to take out the filter cartridge 6.

[0025] The functional principle of the utility model can be explained through the following operation modes:

[0026] The cylinder 1 in the utility model is installed in the oil inlet of the diesel engine. The bottom of the sealing cover on the oil inlet is tightly against the top of the rubber sealing ring 14. When the filter cartridge 6 needs to be replaced, first, the operator unscrews the sealing cover on the oil inlet, and then the operator uses a screwdriver to remove the two locking bolts 10. At this time, the two locking bolts 10 are separated from the obstruction of the connecting block 8. At this time, the sliding block 3 drives the blocking block 5 to move upward under the action of the elastic force of the spring 4. The blocking block 5 squeezes the filter cartridge 6 and drives the connecting block 8 to move upward, so that the filter cartridge 6 slides out of the cylinder 1. At this time, the blocking block 5 slides out of the cylinder 1. Insert it into the mounting ring 9 to seal it, and then the operator takes out the filter cartridge 6 and replaces it. At this time, the blocking block 5 blocks the oil inlet. The operator inserts the replaced filter cartridge 6 into the mounting ring 9, and the bottom of the filter cartridge 6 squeezes the blocking block 5 to slide downward. After the two connecting blocks 8 on the filter cartridge 6 are respectively inserted into the corresponding connecting grooves 13, the operator passes the locking bolt 10 through the connecting hole 11 and inserts it into the threaded hole 12, and tightens the locking bolt 10 with a screwdriver. At this time, the filter cartridge 6 is fixed, and then the sealing cover is tightened on the oil inlet, and the bottom of the sealing cover is tightly against the top of the rubber sealing ring 14.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
