DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1 Figure 2As shown, a filter for an automobile engine that is easy to replace includes a filter housing 1, an oil inlet 2 is provided at the edge position of the upper end of the filter housing 1, an oil outlet 3 is provided at the middle position of the upper end of the filter housing 1, a docking thread 4 is provided in the oil outlet 3, a connecting bayonet 5 is provided at the lower end of the filter housing 1, a positioning mechanism 6 is connected to the connecting bayonet 5, a screwing mechanism 7 is connected in the docking slot 602, the filter housing 1 can be connected to the automobile engine through the docking thread 4, and the screwing mechanism 7 can be installed on both sides of the filter housing 1 through the positioning mechanism 6, the screwing mechanism 7 can facilitate the user to screw the filter housing 1, so that the car owner can replace the filter conveniently and quickly.

[0020] like Figure 3 As shown, the positioning mechanism 6 includes a positioning ring 601 connected to the connecting bayonet 5, an anti-slip pad 605 is arranged in the positioning ring 601, docking slots 602 are opened on both sides of the positioning ring 601, docking screw holes 603 are opened on both sides of the positioning ring 601 above the docking slots 602, and limiting screws 604 are arranged in the docking screw holes 603. The positioning ring 601 is connected to the filter housing 1 through the connecting bayonet 5, the limiting screws 604 are connected to the positioning ring 601 through the docking screw holes 603, and the limiting screws 604 pass through the screw rod 701 through the limiting through hole 702. The screw rod 701 is limited on both sides of the positioning ring 601 by the limiting screws 604, and the mechanism frame 704 is installed on both sides of the positioning ring 601 through the docking slots 602.

[0021] Specifically, the positioning ring 601 is connected to the filter housing 1, and the mechanism frame 704 is installed on both sides of the positioning ring 601, which facilitates the positioning ring 601 to install the screwing mechanism 7 on both sides of the filter housing 1. At the same time, the limit screw 604 can be tightened in the docking screw hole 603 after passing through the limit through hole 702, thereby limiting the screwing rod 701 on both sides of the filter housing 1.

[0022] like Figure 4 As shown, the screwing mechanism 7 includes a mechanism frame 704 fixedly installed in the docking slot 602, a movable shaft 703 is movably installed in the mechanism frame 704, a screwing rod 701 is connected to the movable shaft 703, a limited through hole 702 is provided on the screwing rod 701, movable holes 705 are provided on both sides of the mechanism frame 704, the movable shaft 703 is movably installed in the mechanism frame 704 through the movable holes 705, a connecting hole 706 is provided at the edge of one end of the screwing rod 701, the screwing rod 701 is connected to the movable shaft 703 through the connecting hole 706, the screwing rod 701 is movably installed in the mechanism frame 704 through the movable shaft 703, and the screwing rod 701 is installed on both sides of the positioning ring 601 through the mechanism frame 704.

[0023] Specifically, after loosening the limit screw 604, the screw rod 701 can be unfolded. After unfolding the screw rod 701, the end of the screw rod 701 can be pressed, so that the screw rod 701 drives the filter housing 1 to rotate. After the filter housing 1 rotates, it can be tightened or loosened. Using the screw rod 701 to rotate the filter housing 1 can increase the torque, so that the car owner can replace the filter conveniently and quickly.

[0024] It should be noted that the utility model is a filter for automobile engines that is easy to replace. In actual use, the limit screw 604 is first loosened. Since movable holes 705 are provided on both sides of the mechanism frame 704, the movable shaft 703 is movably installed in the mechanism frame 704 through the movable holes 705. A connecting hole 706 is provided at the edge of one end of the screw rod 701. The screw rod 701 is connected to the movable shaft 703 through the connecting hole 706. Therefore, after the limit screw 604 is loosened, the screw rod 701 can be rotated along the movable shaft 703, so that the screw rod 701 is unfolded. After the screw rod 701 is unfolded, its end can be pressed. After pressing the end of the screw rod 701, it will drive the filter housing 1 to rotate, so that the filter housing 1 can be twisted with the help of the screw rod 701 to remove the old filter. After the old filter is removed, the new filter can be connected to the engine. After the new filter is connected to the engine, the screw rods 701 on both sides of the filter housing 1 can be rotated to install the new filter. After the new filter is installed, the screw rods 701 can be fixed to both sides of the filter housing 1 by the limit screws 604.
