[0020] The bottom outer surface of the support plate 4 is fixedly connected to two rotating seats, the outer surfaces of the two rotating seats are rotatably connected to rotating rods 9, the other ends of the two rotating rods 9 are rotatably connected to connecting blocks 10, the other ends of the two connecting blocks 10 are fixedly connected to second movable cylinders 11, the top outer surface of the bottom plate 2 is fixedly connected to two side plates, the outer surfaces of the two side plates are fixedly connected to second fixed cylinders 12, the two second movable cylinders 11 are movably inserted into the inside of the two second fixed cylinders 12, and a second spring 14 is fixedly connected between the two second fixed cylinders 12 and the two connecting blocks 10. Specifically, the angle between the two rotating rods 9 changes, so that the connecting block 10 pushes the second movable cylinder 11 so that the second movable cylinder 11 slides inside the second fixed cylinder 12, causing the second spring 14 to deform, and the vibration force is buffered in different directions by the second spring 14.

[0021] The first piston 8 is fixedly connected to the outer surface of the bottom of the first movable cylinder 5, and the first piston 8 is slidably connected to the inside of the first fixed cylinder 6. The second piston 13 is fixedly connected to the outer surface of the second movable cylinder 11 located inside the second fixed cylinder 12, and the second piston 13 is slidably connected to the inside of the second fixed cylinder 12. Specifically, the friction force between the first piston 8 and the first fixed cylinder 6 generates damping to absorb the vibration of the first spring 7 to avoid the first spring 7 from vibrating continuously, and the friction force between the second piston 13 and the second fixed cylinder 12 generates damping to absorb the vibration of the second spring 14 to avoid the second spring 14 from vibrating continuously.

[0022] In the specific implementation process, when the oil pump vibrates during operation, the vibration is transmitted to the base 3 and then to the support plate 4. After the support plate 4 vibrates, the first movable cylinder 5 slides in the first fixed cylinder 6 and the first spring 7 is deformed. The vibration force is absorbed and buffered by the first spring 7. The friction force between the first piston 8 and the first fixed cylinder 6 generates damping to absorb the vibration of the first spring 7 to avoid the first spring 7 from vibrating continuously. The angle between the two rotating rods 9 changes, so that the connecting block 10 pushes the second movable cylinder 11 to slide inside the second fixed cylinder 12, so that the second spring 14 is deformed. The vibration force is buffered in different directions by the second spring 14. The second movable cylinder 11 drives the second piston 13 to move. The friction force between the second piston 13 and the second fixed cylinder 12 generates damping to absorb the vibration of the second spring 14 to avoid the second spring 14 from vibrating continuously, thereby effectively buffering the oil pump housing and effectively avoiding the occurrence of aggravated housing vibration caused by the buffer structure of the oil pump housing.

[0023] Embodiment 2: Please refer to Figure 1-Figure 6 The present invention provides a technical solution: the inner surfaces of the first fixed cylinder 6 and the second fixed cylinder 12 are fixedly connected with a pressure pipe 16, the top outer surface of the bottom plate 2 is fixedly connected with a gathering box 17, the other end of the pressure pipe 16 is fixedly connected with the inside of the gathering box 17, a cooling pipe 15 is wound around the outer surface of the oil pump housing body 1, the outer surface of the gathering box 17 is fixedly connected with a delivery pipe 19, the outer surface of the cooling pipe 15 is fixedly connected with a connecting pipe 18, and the delivery pipe 19 is connected to the connecting pipe 18.

[0024] In this embodiment, a first exhaust hole is opened on the outer surface of the first fixed cylinder 6 on one side facing the first movable cylinder 5. Specifically, by setting the first exhaust hole, when the first piston 8 moves toward the first movable cylinder 5 in the second fixed cylinder 12, the air pressure is discharged from the first exhaust hole.

[0025] In this embodiment, a second exhaust hole is opened on the outer surface of the second fixed cylinder 12 on one side facing the second movable cylinder 11. Specifically, by providing the second exhaust hole, when the second piston 13 moves toward the second movable cylinder 11 in the second fixed cylinder 12, air pressure is discharged from the second exhaust hole.

[0026] In this embodiment, the interiors of the first fixed cylinder 6 and the second fixed cylinder 12 are fixedly connected with a balance pipe 23, and a first one-way valve is arranged inside the balance pipe 23. Specifically, the flow direction of the first one-way valve is from the outside of the balance pipe 23 to the inside of the balance pipe 23. When the piston moves upward, the external air pressure enters the first fixed cylinder 6 or the second fixed cylinder 12, so that the air pressure at the bottom of the piston is balanced. When the piston moves downward, the air pressure is prevented from being discharged from the balance pipe 23.

[0027] In this embodiment, a second one-way valve is installed inside the connecting pipe 18. Specifically, the flow direction of the second one-way valve is from the connecting pipe 18 to the cooling pipe 15. The second one-way valve is provided to prevent the backflow of coolant and air pressure.

[0028] In the specific implementation process, when the first piston 8 and the second piston 13 move inside the first fixed cylinder 6 and the second fixed cylinder 12 respectively, the pressure inside the first fixed cylinder 6 and the second fixed cylinder 12 increases, and the air pressure enters the gathering box 17 through the pressure pipe 16 and converges, and then the air pressure enters the connecting pipe 18 through the delivery pipe 19, and pressurizes the cooling pipe 15, so that the coolant in the cooling pipe 15 is in a cooling state, and heat exchange is performed between the coolant and the oil pump housing body 1, thereby increasing the heat dissipation effect thereof.

[0029] Embodiment 3: Please refer to Figure 1-Figure 6 The present invention provides a technical solution: the outer surfaces of the top of the bottom plate 2 are fixedly connected with vertical plates, the outer surfaces of the vertical plates are threaded with screw rods 20, the outer surface of the screw rods 20 is fixedly connected with knobs 22, and the side of the thread away from the knob 22 is rotatably connected with an abutment plate 21.

[0030] In this embodiment, a shock-absorbing pad is fixedly connected to the outer surface of the abutting plate 21 . Specifically, the shock-absorbing pad increases the shock-absorbing capacity between the abutting plate 21 and the base 3 .

[0031] During the specific implementation process, after the oil pump housing body 1 is connected to the support plate 4, the knob 22 is turned, the knob 22 drives the screw 20 to rotate, and the screw 20 drives the abutment plate 21 to move, so that the abutment plate 21 abuts against the surface of the base 3, thereby avoiding horizontal lateral vibration of the oil pump housing body 1.

[0032] Working principle: When the present invention is in use, when the oil pump vibrates during operation, the vibration is transmitted to the base 3 and then to the support plate 4. After the support plate 4 vibrates, the first movable cylinder 5 slides in the first fixed cylinder 6 and the first spring 7 is deformed. The vibration force is absorbed and buffered by the first spring 7. The friction force between the first piston 8 and the first fixed cylinder 6 generates damping to absorb the vibration of the first spring 7 to avoid the first spring 7 from vibrating continuously. The angle between the two rotating rods 9 changes, so that the connecting block 10 pushes the second movable cylinder 11 to slide inside the second fixed cylinder 12, so that the second spring 14 is deformed. The vibration force is buffered in different directions by the second spring 14. The second movable cylinder 11 drives the second piston 13 to move. The friction force between the second piston 13 and the second fixed cylinder 12 generates damping to absorb the vibration of the second spring 14 to avoid the second spring 14 from vibrating continuously, thereby effectively buffering the oil pump housing and effectively avoiding the occurrence of aggravated housing vibration caused by the buffer structure of the oil pump housing.

[0033] When the first piston 8 and the second piston 13 move inside the first fixed cylinder 6 and the second fixed cylinder 12 respectively, the pressure inside the first fixed cylinder 6 and the second fixed cylinder 12 increases, and the air pressure enters the convergence box 17 through the pressure pipe 16 and converges, and then the air pressure enters the connecting pipe 18 through the delivery pipe 19 and applies pressure to the cooling pipe 15, so that the coolant in the cooling pipe 15 is in a cooling state, and heat exchange is performed between the coolant and the oil pump housing body 1, thereby increasing the heat dissipation effect thereof.

[0034] After the oil pump housing body 1 is connected to the support plate 4, the knob 22 is turned, the knob 22 drives the screw 20 to rotate, and the screw 20 drives the abutment plate 21 to move, so that the abutment plate 21 abuts against the surface of the base 3, thereby preventing the oil pump housing body 1 from generating horizontal lateral vibration.

[0035] Although 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.
