Embodiment 1

[0027] see Figure 1-5 , according to an embodiment of the present invention, an oil filter for disassembling and installing oil leakage prevention includes a housing 1, a sealing groove 2 at the top of the housing 1, a sealing ring 28 is arranged in the sealing groove 2, and the One side of the sealing groove 2 is provided with a metal splint 3, and several dirty oil inlets 4 are arranged between the sealing groove 2 and the metal splint 3, and a clean oil outlet 5 is provided in the middle of the metal splint 3, and the clean oil outlet 5 A central pipe 6 is provided inside, and a filter paper 7 is provided on the outside of the central pipe 6, a check valve 9 is provided at the bottom of the filter paper 7, a mounting part 8 is provided at the bottom of the housing 1, and a symmetrical design is arranged inside the mounting part 8. There is a cavity 10, a worm wheel 11 is arranged in the cavity 10, the middle part of the worm wheel 11 is connected with the cavity 10 through...

Embodiment 2

[0030] see image 3 and Figure 4 , for the clean oil outlet 5, both ends of the clean oil outlet 5 are provided with internal threads 27. As for the central pipe 6 , several filter element through holes 20 are provided on the central pipe 6 . For the mounting part 8 , a connecting pipe 21 is provided in the middle of the mounting part 8 , and an external thread 26 is provided on the outside of one end of the connecting pipe 21 , and the connecting pipe 21 is matched with the clear oil outlet 5 .

[0031] Through the above scheme of the present invention, the beneficial effect is that internal threads are provided at both ends of the clean oil outlet 5, and a connecting pipe 21 is provided in the middle of the mounting part 8, and an external thread is provided on the outside of the connecting pipe 21, thereby facilitating installation. The effect of the oil filter and the mounting part 8 is convenient for dismounting.

Embodiment 3

[0033] see Figure 5 , for the cavity 10 , a baffle 22 is provided in the cavity 10 , and the baffle 22 is located on one side of the worm wheel 11 . For the cavity 10 , a fixed ring 23 is provided in the cavity 10 , and the end of the worm 15 away from the male gear 16 penetrates through the fixed ring 23 and extends into the fixed ring 23 . As for the rotating shaft 18 , the rotating shaft 18 is covered with a fixed sleeve 24 , and the fixed sleeve 24 is connected to the inner wall of the cavity 10 through a connecting rod 25 .

[0034] Through the above solution of the present invention, the beneficial effect is that by providing the baffle plate 22 in the cavity 10 , oil leakage from the cavity 10 is avoided. By providing the fixing ring 23 and the fixing sleeve 24 , the worm screw 15 and the rotating shaft 18 can be used as position-limiting supports.

[0035]In summary, with the help of the above-mentioned technical solution of the present invention, the working princi...

Abstract

The invention discloses an oil filter capable of preventing oil leakage during dismounting and mounting. The oil filter capable of preventing oil leakage during dismounting and mounting comprises a shell, a seal groove is formed in the inner top of the shell, a seal ring is arranged in the seal groove, a metal clamping plate is arranged on one side of the seal groove, multiple dirty oil inlets areformed between the seal groove and the metal clamping plate, a clean oil outlet is formed in the middle of the metal clamping plate, a center pipe is arranged in the clean oil outlet, filter paper isarranged on the outer side of the centre pipe, a check valve is arranged on the bottom of the filer paper, a mounting part is arranged on the bottom of the shell, cavities are symmetrically formed inthe mounting part, worm gears are arranged in the cavities, the centers of the worm gears are connected with the cavities through center shafts, one sides of the worm gears are provided with connecting blocks, the ends, away from the worm gears, of the connecting blocks are provided with oil blocking plates, worms are arranged on one sides of the worm gears in an engaged manner, and one ends of the worms are provided with second convex gears in a penetrating manner. The oil filter has the beneficial effects that oil leakage of the oil filter is blocked, and the oil leakage during dismountingof the oil filter can be avoided.

Description

technical field [0001] The invention relates to a filter, in particular to an engine oil filter which can be disassembled and installed to prevent oil leakage. Background technique [0002] Oil filter, also known as oil grid. It is used to remove impurities such as dust, metal particles, carbon deposits and soot particles in the oil to protect the engine. Oil filters are divided into full-flow and split-flow. The full-flow filter is connected in series between the oil pump and the main oil passage, so it can filter all the lubricating oil entering the main oil passage. The shunt cleaner is connected in parallel with the main oil passage, and only filters part of the lubricating oil sent by the oil pump. [0003] When the engine is running, the oil filtered out of impurities needs to be transported to the oil passage to lubricate the parts. The oil filter is one of the important parts of the engine lubrication system, which is used to remove dust, metal particles, carbon...
