The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0022] The utility model discloses a novel bottom shell of an automobile oil pump, which is mainly used in the bottom shell of a traditional automobile oil pump. When used, it is necessary to align the screws one by one with the multiple screw holes on the bottom shell, and then tighten the screws respectively to fix the bottom shell on the engine. The alignment action needs to be repeated, the tightening of the screws is cumbersome, and the installation efficiency is low.

[0023] Reference Figure 1 、 Figure 2 and Figure 3 A novel bottom shell of an automobile oil pump includes a bottom shell body 1, screws 11 and a mounting fixture 5, and also includes:

[0024] Pressing mechanism: The pressing mechanism is located on the bottom shell body 1;

[0025] The top outer wall of the mounting fixture 5 is provided with connecting sleeves 6 distributed at equal distances, the top outer wall of the connecting sleeve 6 is provided with guide holes, the top outer wall of the mounting fixture 5 is provided with embedding holes 13 distributed at equal distances, the top outer wall of the bottom shell body 1 is provided with first screw holes 3 distributed at equal distances, the top outer wall of the bottom shell body 1 is provided with a gasket 2, the top outer wall of the gasket 2 is provided with second screw holes 4 distributed at equal distances, and the connecting sleeves 6 correspond to the positions of the first screw holes 3 and the second screw holes 4 respectively.

[0026] During the specific working process, the connecting sleeve 6 on the mounting jig 5 corresponds to the first screw hole 3 on the bottom shell body 1 and the second screw hole 4 on the washer 2 respectively. The mounting jig 5 is moved out under the pressure of the pressing mechanism, and the screw 11 is placed upside down in the guide hole of the connecting sleeve 6. Then, the mounting jig 5 is moved upward. At the same time, the pressing mechanism limits the mounting jig 5. The screw 11 is tightened to the first screw hole 3 and the second screw hole 4 through the embedded hole 13 at the bottom of the mounting jig 5 to stabilize the installation of the bottom shell body 1 and the engine.

[0027] Among them, the diameter of the guide hole is smaller than the diameter of the first screw hole 3, and the guide hole is set to a wide-upper-narrow-down structure. In this way, the screw 11 can be placed in the connecting sleeve 6 for limitation, and the diameter of the embedded hole 13 only needs to be able to pass the installation tool. The guide hole with a wide-upper-narrow-down structure can better accommodate the screw 11 without hindrance. While limiting the screw 11, the screw 11 can also be better installed from the bottom, and the use effect is good.

[0028] Among them, the screw 11 is located inside the connecting sleeve 6, and the screw 11 is respectively adapted to the first screw hole 3 and the second screw hole 4. In this way, the screw 11 is tightened to the first screw hole 3 and the second screw hole 4 at the bottom of the mounting fixture 5 through the mounting tool, thereby fixing the bottom shell body 1 and the washer 2 to the engine stably.

[0029] It should be noted that the bottom shell body 1 is made of plastic. During actual use, the screws 11 of the bottom shell body 1 should be tightened using appropriate installation tools (such as a torque wrench or electric wrench, etc.) in the order and torque specified in the maintenance manual or the manufacturer. When tightening the screws 11, the principle of tightening diagonally from both sides to the middle should be followed to ensure that the bottom shell body 1 is evenly stressed.

The connecting groove 17 is connected to the second limiting groove 18. Two connecting rods 15 are fixedly connected to the outer wall of one side of the pressing block 12, one end of the connecting rod 15 is fixedly connected to the limiting ring 16, and a return spring 19 is provided on the circumferential outer wall of the connecting rod 15. The return spring 19 is located between the pressing block 12 and the first limiting groove 14.

[0033] Specifically, by pressing the pressing block 12 and squeezing the return spring 19, the connecting rod 15 moves inward, and the limiting ring 16 moves into the second limiting groove 18, so that the pressing block 12 is limited in the first limiting groove 14, and the installation jig 5 can be moved downward. After the installation jig 5 places the screw 11, it moves to the top of the pressing block 12, the return spring 19 is reset, and the limiting ring 16 is limited in the second limiting groove 18, so that the pressing block 12 moves out of the first limiting groove 14, and then the installation jig 5 is fixed and limited on both sides.

[0034] Among them, the pressing block 12 is adapted to the first limiting groove 14, the groove depth of the first limiting groove 14 is consistent with that of the second limiting groove 18, the limiting ring 16 is located in the second limiting groove 18, and the connecting rod 15 is located in the connecting groove 17. In this way, when the pressing block 12 is pressed, the pressing block 12 can be limited in the first limiting groove 14. At the same time, the limiting ring 16 moves in the second limiting groove 18, the same distance as the pressing block 12 moves, and moves inward or outward to contact the limit.

[0037] Specifically, the engine oil inside the bottom shell body 1 is discharged through the oil drain port 7 and flows downward into the oil pan. The control valve 8 is used to close and open the oil drain port 7 to control the oil discharge condition of the oil drain port 7.

[0038] Working principle: When in use, press the pressing block 12 on both sides, the pressing block 12 is limited in the first limiting groove 14, squeezing the return spring 19, moving the mounting fixture 5 out, and then turning the screw 11 upside down into the guide hole of the connecting sleeve 6, and then moving the mounting fixture 5 upward. When moving to the top of the pressing block 12, the return spring 19 is reset, and the pressing block 12 is moved out in the first limiting groove 14 to limit the mounting fixture 5. Then, at the bottom of the mounting fixture 5, the screw 11 is tightened to the first screw hole 3 and the second screw hole 4 through the embedded hole 13, and then the bottom shell body 1 is fixed to the engine by the screw 11 and the washer 2. Between the bottom shell body 1 and the washer 2, the rubber pad 9 is limited in the fixing groove 10, adding an extra layer of fixation between the bottom shell body 1 and the washer 2. The control valve 8 is used to close and open the oil drain port 7. The engine oil inside the bottom shell body 1 can be discharged through the oil drain port 7.
