EMBODIMENT

[0024] Referring to Figures 1-4 In the case where other parts are same with embodiment 1, the difference between this embodiment and embodiment 1 is:

[0025] The bottom base 3 is provided with a matched maintenance plate 9 corresponding to the mounting cavity and the mounting groove on the side away from the shell 1, the bottom base 3 is connected with the maintenance plate 9 through bolts, the bottom base 3 is provided with a matched threaded groove on the side corresponding to the mounting groove, the bottom base 3 and the maintenance plate 9 are jointly installed with a tail plug 10 through the threaded groove, the top spring 8 abuts against the end of the tail plug 10 away from the locking plate 7, the tail plug 10 is provided with a slot for inserting a screwdriver on the end outside the bottom base 2, the tail plug 10 and the bottom base 3 are jointly provided with a positioning groove 12 outside, the maintenance plate 9 is arranged, so that the mounting cavity and the mounting groove and the like can be conveniently processed and the maintenance of the internal parts is convenient, that is, when the top spring 8, the locking plate 7 and the ratchet wheel 6 need to be replaced or maintained, the maintenance plate 9 can be directly removed through the bolts, so that the scheme has better maintenance convenience when used, and the tail plug 10 is arranged, which not only can adjust the pressure of the top spring 8, but also can further improve the convenience of replacing the top spring 8, and the positioning groove 12 is arranged, so that the position of the tail plug 10 can be determined when the tail plug 10 is loosened, so that the tail plug 10 is not loosened in time.

[0026] The maintenance plate 3 is provided with a matched limiting groove on the side corresponding to the locking plate 7, the locking plate 7 is provided with a matched limiting protrusion 11 on the side corresponding to the limiting groove, the outer ring surface of the bottom base 3 is polygonal, each side is provided with an anti-skid line, the cross section of the linkage block 5 is hexagonal, the outer ring surface of the linkage block 5 is provided with an anti-skid line, and the limiting groove and the limiting protrusion 11 can limit the locking plate 7 and improve the stability.

[0027] Principle and advantages: in the use process of the utility model, the filter main body 2 is installed inside the shell 1, that is, the oil of the external automobile enters the inside of the shell 1 and is returned to the automobile after being filtered by the filter main body 2, so that the oil filtering effect is realized, and when the filter is installed or disassembled by personnel, the bottom base 3 and the shell 1 are connected through threads, that is, the personnel only need to rotate the bottom base 3 to combine or separate the two, the bottom base 3 is counterclockwise in the scheme, and clockwise for disassembly, so that the installation or disassembly is more convenient.

[0028] Thus, when the ratchet wheel 6 rotates counterclockwise, the inclined surface of the ratchet wheel 6 is in contact with the inclined surface of the locking plate 7, at this time, when the ratchet wheel 6 rotates, it pushes the locking plate 7 to shrink into the mounting groove, but because the mounting groove is provided with the top spring 8, the locking plate 7 cannot directly shrink into the mounting groove, that is, at this time, when the ratchet wheel 6 rotates, it pushes the base 3 to rotate synchronously under the driving of the locking plate 7, that is, the base 3 is gradually connected with the shell 1 at this time, and in this process, the resistance between the base 3 and the shell 1 gradually increases, and the gradually increasing resistance makes the locking plate 7 gradually pressed into the mounting groove by the ratchet wheel 6, until the base 3 and the shell 1 reach the preset connection tightness, at this time, the resistance is greater than the elastic force of the top spring 8, that is, when the ratchet wheel 6 is rotated by the wrench outside, the rotation of the ratchet wheel 6 can only push the locking plate 7 to shrink into the mounting groove, and it cannot drive the base 3 to continue to rotate, that is, the effect of torque limiting is realized, so as to prevent the non-professional personnel from replacing it, and the phenomenon that the threads between the base 3 and the shell 1 are damaged due to over-tightening.

[0029] Further, in the above process, when the base 3 needs to be disassembled, the linkage block 5 is directly rotated clockwise, at this time, the plane of the ratchet wheel 6 is in contact with the plane of the locking plate 7, that is, at this time, the ratchet wheel 3 is in a fixed connection state between the locking plate 7 and the base 3, so that the ratchet wheel 3 can directly drive the base 3 to rotate when the ratchet wheel 3 rotates, which facilitates the disassembly of the base 3 by personnel; Therefore, when the present scheme is used, through the cooperation of the top spring 8, the locking plate 7 and the ratchet wheel 6, the rotation torque of the base 3 can be restricted when the base 3 is installed, so as to prevent the base 3 and the shell 1 from being over-tightened due to excessive torque, that is, the phenomenon that the threads between the two are damaged is avoided, and the convenience of disassembling the base 3 by personnel is not affected.

[0030] It should be further pointed out that the installation of the maintenance plate 9 makes the installation cavity and the installation groove convenient to process and the internal parts convenient to maintain, that is, when the top spring 8, the locking plate 7 and the ratchet wheel 6 need to be replaced or maintained, the maintenance plate 9 can be directly removed by bolts, which makes the present scheme have good maintenance convenience when used, and the setting of the tail plug 10 not only can adjust the pressure of the top spring 8, but also can further improve the convenience of replacing the top spring 8, and the setting of the positioning groove 12 makes the position of the tail plug 10 determined by the positioning groove 12 when the tail plug 10 is rotated, so as to avoid the tail plug 10 from loosening without timely knowing the position limiting groove and the position limiting protrusion 11, which can limit the locking plate 7 and improve the stability.

[0031] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
