Detailed implementation mode

[0024] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0025] Embodiment 1

[0026] This embodiment provides a diesel engine filter equipped with a quick replacement device. Referring to Figures 1-4 , this diesel engine filter includes a filter housing 1 and a filter seal cover 2 for sealing the filter housing 1. A connecting thread port 3 for connecting to the diesel engine fuel pipe is opened at the top of the filter seal cover 2. A sealing gasket 4 for connecting and sealing the filter housing 1 and the filter seal cover 2 is provided between the filter housing 1 and the filter seal cover 2. A quick replacement mechanism 5 is arranged inside the filter housing 1, and a quick installation mechanism 6 is arranged at the top of the quick replacement mechanism 5;

[0027] During use, the filter housing 1 and the filter sealing cover 2 are installed and fixed by bolts. The joint between the filter housing 1 and the filter sealing cover 2 is sealed by a gasket 4 provided between them. The connecting threaded port 3 provided at the top of the filter sealing cover 2 facilitates connection with the diesel engine, which is convenient to use. With the gasket 4 provided, it is convenient to disassemble and replace the internal components of the filter housing 1. The operation is simple and fast, and it is convenient to use. With the quick replacement mechanism 5 provided, it is convenient for installation and fixation, the operation is simple, and it is convenient to use.

[0028] Specifically, the quick replacement mechanism 5 includes a mounting frame 51 provided inside the filter housing 1. The mounting frame 51 is provided with a first filter element 52. Both sides of the bottom of the mounting frame 51 are fixedly connected with mounting blocks 53. An installation groove 54 adapted to the mounting blocks 53 is opened inside the filter housing 1. The mounting blocks 53 are inserted into the installation groove 54. A second filter element 55 is provided inside the mounting frame 51;

[0029] During use, by placing the mounting frame 51 inside the filter housing 1, the mounting blocks 53 provided at the bottom of the mounting frame 51 are inserted into the installation groove 54 opened inside the filter housing 1, so as to fix the mounting frame 51 inside the filter housing 1. The mounting frame is provided with a first filter element 52, and impurities in the diesel are filtered by the first filter element. The diesel is secondarily filtered by the provided second filter element 55. The pore diameters of the first filter element 52 and the second filter element 55 are different. By the way of inserting the mounting frame 51 and the filter housing 1, it is convenient for disassembly and replacement. The operation is simple and fast, and it is convenient to use.

[0030] Embodiment 2

[0031] Different from Embodiment 1, when filtering diesel, the single-layer filtering setting will result in poor filtering effect, and the double-layer setting has a good filtering effect but is not convenient for installation. For this reason, referring to Figures 1-4 , the quick installation mechanism 6 connected to the second filter element 55 includes a connecting block 61. Placement grooves 66 adapted to the connecting block 61 are opened on both sides of the top of the mounting frame 51. The connecting block 61 is snap-fitted into the placement grooves 66. A fixing rod 63 is slidably connected inside the groove opened on the connecting block 61. Fixing holes 67 adapted to the fixing rod 63 are opened on the side of the placement grooves 66. The fixing rod 63 is inserted into the fixing holes 67.

[0032] During use, the second filter element 55 can be placed inside the placement groove 66 opened at the top of the mounting frame 51 by snap-fitting the connection block 61 with the placement groove 66. Push the fixing rod 63 provided inside the connection block 61 to slide. The fixing rod 63 is adapted to the fixing hole 67 opened inside the placement groove 66. By inserting the fixing rod 63 into the fixing hole 67, the second filter element 55 can be fixed to the mounting frame 51, which is convenient for installation and disassembly, with simple and quick operation and convenient use.

[0033] Further, referring to Figure 4 、 Figure 5 , a sliding block 62 is arranged inside the slot of the connection block 61. The sliding block 62 is slidably connected to the connection block 61, and one end of the sliding block 62 arranged inside the connection block 61 is fixedly connected to the fixing rod 63. By manually pushing the sliding block 62 to move inside the connection block 61, the top of the sliding block 62 is slotted, which is convenient for personnel to operate, so as to facilitate the sliding block 62 to push the fixing rod 63 to move, and is convenient to use.

[0034] Furthermore, referring to Figure 5 , a limiting rod 64 is fixedly connected inside the slot of the connection block 61. The sliding block 62 is arranged outside the limiting rod 64, and the sliding block 62 is slidably connected to the limiting rod 64. The sliding block 62 is subjected to the thrust applied by the operator, so that the sliding block 62 slides outside the limiting rod 64 under force, and the stability of the sliding block 62 during sliding is improved through the limiting rod 64.

[0035] Among them, a spring 65 is arranged inside the connection block 61. The spring 65 is fixedly connected between the sliding block 62 and the slot of the connection block 61. The spring 65 arranged on the side is compressed during the sliding of the sliding block 62, which is convenient for the sliding block 62 to restore its original state and convenient to use.

[0036] The above is only the preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, makes equivalent replacement or change, and should be covered by the protection scope of the present application.
