[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, an animal oil filter fixing device comprises a mounting member 1 and a rotating member 2, both of which are annular plate structures, a mounting groove 3 is provided on the upper surface of the mounting member 1, and the lower end of the rotating member 2 is rotatably connected to a connecting member 4 that is slidably engaged with the mounting groove 3, the connecting member 4 is an annular plate structure, the connecting member 4 and the mounting groove 3 are connected through a first connecting component, the bottom of the rotating member 2 is also fixedly connected to a fixed inner plate 17, the fixed inner plate 17 is located on the inner side of the connecting member 4, a receiving groove 18 is formed between the fixed inner plate 17 and the connecting member 4, an extrusion ring 12 is slidably installed in the receiving groove 18, the extrusion ring 12 and the receiving groove 18 are connected through a second connecting component, a limiting groove 9 is provided on the inner wall of the mounting groove 3, a limiting block 11 that is slidably engaged with the limiting groove 9 is provided in the limiting groove 9, the limiting block 11 is an arc-shaped plate structure, the upper side of the inner arc surface of the limiting block 11 is set as an inclined surface, and the limiting block 11 is installed at the bottom of the connecting member 4 through a third connecting component.

[0021] The first connecting assembly includes guide blocks 8 , three guide blocks 8 are fixedly connected to the outer wall of the connecting member 4 , and a guide groove 7 slidably engaged with the guide blocks 8 is formed on the inner wall of the mounting groove 3 .

[0022] The sliding engagement between the guide block 8 and the guide groove 7 can limit the rotation of the connecting member 4 so that the connecting member 4 can only move up and down in the installation groove 3 .

[0023] Among them, an internal thread is opened on the inner wall of the extrusion ring 12, and an external thread is opened on the outer wall of the fixed inner plate 17. The extrusion ring 12 and the fixed inner plate 17 are connected by threaded cooperation. The outer wall of the extrusion ring 12 is fixedly connected to three movable blocks 15, and the inner wall of the connecting piece 4 is opened with a movable groove 16 that slides in fit with the movable block 15.

[0024] The sliding fit between the movable block 15 and the movable groove 16 can limit the rotation of the extrusion ring 12 so that the extrusion ring 12 can only move up and down in the receiving groove 18, and the extrusion ring 12 is connected to the fixed inner plate 17 by the threaded fit between the internal thread and the external thread.

[0025] The upper end of the limiting block 11 is provided with two slide grooves 13 , in which a slider 14 is slidably installed, and the slider 14 is fixedly connected to the bottom of the connecting member 4 .

[0028] The limit block 11 can be reset by the reset spring 10 .

[0029] The horizontal plane where the bottom of the guide block 8 is located is below the horizontal plane where the bottom of the connecting member 4 is located.

[0030] Such an arrangement can ensure that when the guide block 8 contacts the bottom of the installation groove 3 , there is still a gap between the lower end of the connecting member 4 and the bottom of the installation groove 3 , and the gap can be used for the movement of the limit block 11 .

[0031] The bottom of the mounting member 1 is fixedly connected with a fixing plate 5 , which is an annular plate. A plurality of fixing holes 6 are formed on the side wall of the fixing plate 5 , and the plurality of fixing holes 6 are arranged in an annular array.

[0032] The fixing plate 5 can be mounted on the inner wall of the filter by the cooperation of the external fixing bolts and the fixing holes 6 .

[0033] The utility model provides an animal oil filter fixing device, and the specific working principle is as follows:

[0034] When in use, place a filter screen whose size is larger than the aperture of the mounting groove 3 on the mounting groove 3, align the guide block 8 on the connecting piece 4 with the guide groove 7 on the inner wall of the mounting groove 3 and insert it, so as to press the filter screen into the mounting groove 3, and the filter screen will cover the bottom and the inner wall of the mounting groove 3. Since the horizontal plane where the bottom of the guide block 8 is located is below the horizontal plane where the bottom of the connecting piece 4 is located, at this time, the three guide blocks 8 are just pressed on the upper end of the filter screen, and there is still a gap between the lower end of the connecting piece 4 and the bottom of the mounting groove 3, and the gap can be used for the movement of the limit block 11; specifically, rotate the rotating member 2, the rotating member 2 will drive the fixed inner plate 17 to rotate, and the connecting piece 4 is restricted by the guide block 8 and cannot rotate, and the extrusion ring 12 is restricted by the slider 14 and cannot rotate, and the extrusion ring 12 is connected to the fixed inner plate 17 by threaded cooperation. When the fixed inner plate 17 rotates, the extrusion ring 12 will Move up and down in the storage groove 18, control the extrusion ring 12 to move downward, so that the bottom of the extrusion ring 12 presses the inclined surface inside the limit block 11, so that the limit block 11 is inserted into the limit groove 9, thereby fixing the connecting member 4 and the mounting member 1 together. At the same time, in the process of the three limit blocks 11 being inserted into the limit groove 9, the side of the filter screen will be squeezed into the limit groove 9, thereby pulling the filter screen, so that the installed filter screen is in a stretched state, and then continue to move the extrusion ring 12 downward, so that the bottom of the extrusion ring 12 reaches the bottom of the mounting groove 3, thereby pressing the filter screen in the stretched state, and further improving the firmness of the filter screen after installation. When disassembly is required, only the rotating member 2 needs to be rotated in the opposite direction to restore the extrusion ring 12 to its initial position, and the reset spring 10 inside the limit groove 9 will squeeze the limit block 11 out of the limit groove 9, and then pull out the connecting member 4 to complete the disassembly work.

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
