DETAILED DESCRIPTION

[0021] The technical solution of the utility model is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0022] Example 1: Figure 1A new compressor connecting rod shown in FIG. 1 includes a piston 4, a crankshaft end 1 and a connecting rod 7. The connecting rod 7 is located between the piston end 4 and the crankshaft end 1 and integrally connects the piston end 4 and the crankshaft end 1. A crankshaft connecting hole 2 is provided on the crankshaft end 1, and a piston connecting hole 5 is provided on the piston end 4; Figure 4 As shown, the crankshaft connecting hole 2 is connected to the crankshaft head 12, and the piston connecting hole 5 is connected to the piston 14. At the crankshaft end 1, a first groove body 3 is provided in the crankshaft connecting hole 2. The first groove body 3 is arranged in the vertical direction, that is, arranged along the axial direction of the crankshaft connecting hole 2. The crankshaft connecting hole 2 is adapted to the crankshaft head 12 in size. When the crankshaft connecting hole 2 is connected to the crankshaft head 12, an oil path will be formed between the first groove body 3 and the crankshaft head 12. It should be noted that the upper part of the first groove body 3 is located inside the crankshaft connecting hole 2 (such as Figure 2 As shown in the figure, an oil passage 8 is arranged inside the connecting rod 7, and the oil passage 8 connects the crankshaft connecting hole 2 and the piston connecting hole 5, and the two ends of the oil passage 8 are respectively located at the middle position of the inner wall of the crankshaft connecting hole 2 and the middle position of the inner wall of the piston connecting hole 5, and the upper part of the first groove body 3 is higher than the position of the oil passage 8, that is, the length of the first groove body 3 will be greater than half of the axial length of the crankshaft connecting hole 2; when the crankshaft head 12 and the connecting rod 7 rotate relative to each other, when the oil hole on the crankshaft head 12 is aligned with the oil passage 8, the oil inside the crankshaft head 12 will enter the oil passage 8, and when the oil hole on the crankshaft head 12 and the oil passage 8 are staggered, the oil inside the crankshaft head 12 will adhere to the inner wall of the crankshaft connecting hole 2, so that the oil seeps into the crankshaft connecting hole 2 and the contact surface of the crankshaft head 12, thereby improving the lubrication effect between the crankshaft head 12 and the crankshaft connecting hole 2 and reducing wear.

[0023] Due to the existence of the first groove body 3, when the crankshaft head 12 and the crankshaft connecting hole 2 rotate relative to each other, the first groove body 3 will rotate circumferentially relative to the outer surface of the crankshaft head 12, thereby collecting the oil on the outer surface of the crankshaft head 12 in the first groove body 3, and as the crankshaft connecting hole 2 and the crankshaft head 12 continue to rotate, the oil in the first groove body 3 will gradually increase and flow toward the two ends of the first groove body 3, thereby quickly increasing the oil area between the crankshaft connecting hole 2 and the crankshaft head 12, that is, the excess oil transported from the crankshaft head 12 will be collected in the first groove body 3, and since the lower end of the first groove body 3 extends to the end face of the crankshaft connecting hole 2, that is, the lower end of the first groove body 3 is in a through state, excess liquid will seep out from the lower end of the first groove body 3 and fall on the surface of the crankshaft 13, so that a stable thickness of oil film can be formed between the crankshaft head 12 and the crankshaft connecting hole 2. In addition, since the upper part of the first groove body 3 is located inside the crankshaft connecting hole 2, when the crankshaft connecting hole 2 and the crankshaft head 12 are connected, the upper part of the first groove body 3 is in a closed state. When the oil enters the first groove body 3, a certain vacuum degree can be generated inside the first groove body 3 to ensure that the oil can be stored in the first groove body 3. When the crankshaft 13 moves, an oil film can be quickly formed between the crankshaft head 12 and the crankshaft connecting hole 2, thereby greatly improving the performance of the compressor.

[0024] like Figures 1 to 3 As shown, a second groove body 6 is provided in the piston connection hole 5. Similarly, the second groove body 6 is arranged in the vertical direction, that is, the second groove body 6 is arranged axially along the piston connection hole 5, and the two ends of the second groove body 6 penetrate the two ends of the piston connection hole 5. When the oil passage 8 on the connecting rod 7 is aligned with the oil hole in the piston 14, the oil is transported from the crankshaft end 1 to the piston of the piston end 4 through the oil passage 8. When the oil passage 8 on the connecting rod 7 and the oil hole in the piston 14 are staggered, the oil will adhere to the contact surface between the piston connection hole 5 and the piston 14, thereby improving the lubrication effect between the piston 14 and the piston connection hole 5 and reducing wear. The second groove body 6 can also collect the oil on the contact surface between the piston 14 and the piston connection hole 5, and the oil moves toward the two ends of the second groove body 6, quickly diffuses and increases the lubricating oil liquid level between the piston 14 and the piston connection hole 5, and the excess oil can also seep out from both sides of the second groove body 6 and flow to other structures inside the compressor, thereby improving the performance of the compressor.

[0025] like Figure 4As shown, the crankshaft end 1 is sleeved on the outside of the crankshaft head 12, and the lower surface of the crankshaft end 1 is separated from the crankshaft 13; the piston end 4 is sleeved on the connecting column inside the piston 14, and the lower surface of the piston end 4 is in contact with the base inside the piston 14, so that the installation stability of the connecting rod 7 can be guaranteed. At the position of the crankshaft end 1, there is no friction and wear between the lower surface of the crankshaft end 1 and the crankshaft 13. An expansion groove 9 is provided on the lower surface of the crankshaft end 1, and the expansion groove 9 is flush with or connected to the lower end of the first slot body 3. On the one hand, the expansion groove 9 can reduce the contact area between the crankshaft connecting hole 2 and the crankshaft head 12, reduce the rotational friction and wear between the two, and on the other hand, it can quickly guide the excess oil inside the first slot body 3 to the surface of the crankshaft 13.

[0026] It should also be noted that in this solution, the first slot body 3 and the second slot body 6 are arranged staggered with the position of the oil passage 8. Specifically, the first slot body 3 located inside the crankshaft connecting hole 2 is staggered with the oil passage 8. When the oil hole on the crankshaft head 12 is aligned with the oil passage 8, the oil inside the crankshaft head 12 will only be transported to the inside of the oil passage, and when the oil hole on the crankshaft head 12 is staggered with the oil passage 8, the oil hole on the crankshaft head 12 will contact the inner surface of the crankshaft connecting hole 2, so that part of the oil will adhere to the inner surface of the crankshaft connecting hole 2 or the first slot body 3, so as to avoid the first slot body 3 affecting the oil delivery efficiency of the connecting rod 7. If the positions of the first slot body 3 and the oil passage 8 are arranged correspondingly, when the oil hole on the crankshaft head 12 delivers oil to the oil passage 8, part of the oil will be delivered to the first slot body 3 and seep to the outside, reducing the oil delivery efficiency. Therefore, it is necessary to stagger the first slot body 3 and the oil passage 8. Similarly, the second tank body 6 also needs to be staggered with the oil passage 8 . The principle is consistent with the design concept of the first tank body 3 , which will not be elaborated here.

[0027] A reinforcement part 11 is provided at the connection between the connecting rod 7 and the crankshaft end 1, and at the connection between the connecting rod 7 and the piston end 4. The reinforcement part 11 is a thickened structure, which is equivalent to a rib-like structure, and increases the effective connection area between the connecting rod 7 and the outer surface of the crankshaft end 1, and the outer surface of the piston end 4, thereby enhancing the connection strength. Similarly, in order to improve the strength and quality between the connecting rod 7, the crankshaft end 1, and the piston end 4, the connecting rod 7, the crankshaft end 1, and the piston end 4 are also blackened during the actual production process.

[0028] Example 2: Figure 1 A new compressor connecting rod shown in FIG. 1 includes a piston 4, a crankshaft end 1 and a connecting rod 7. The connecting rod 7 is located between the piston end 4 and the crankshaft end 1 and integrally connects the piston end 4 and the crankshaft end 1. A crankshaft connecting hole 2 is provided on the crankshaft end 1, and a piston connecting hole 5 is provided on the piston end 4; Figure 4As shown, the crankshaft connecting hole 2 is connected to the crankshaft head 12, and the piston connecting hole 5 is connected to the piston 14. At the crankshaft end 1, a first groove body 3 is provided in the crankshaft connecting hole 2. The first groove body 3 is arranged in the vertical direction, that is, arranged along the axial direction of the crankshaft connecting hole 2. The crankshaft connecting hole 2 is adapted to the crankshaft head 12 in size. When the crankshaft connecting hole 2 is connected to the crankshaft head 12, an oil path will be formed between the first groove body 3 and the crankshaft head 12. It should be noted that the upper part of the first groove body 3 is located inside the crankshaft connecting hole 2 (such as Figure 2 As shown in the figure, an oil passage 8 is arranged inside the connecting rod 7, and the oil passage 8 connects the crankshaft connecting hole 2 and the piston connecting hole 5, and the two ends of the oil passage 8 are respectively located at the middle position of the inner wall of the crankshaft connecting hole 2 and the middle position of the inner wall of the piston connecting hole 5, and the upper part of the first groove body 3 is higher than the position of the oil passage 8, that is, the length of the first groove body 3 will be greater than half of the axial length of the crankshaft connecting hole 2; when the crankshaft head 12 and the connecting rod 7 rotate relative to each other, when the oil hole on the crankshaft head 12 is aligned with the oil passage 8, the oil inside the crankshaft head 12 will enter the oil passage 8, and when the oil hole on the crankshaft head 12 and the oil passage 8 are staggered, the oil inside the crankshaft head 12 will adhere to the inner wall of the crankshaft connecting hole 2, so that the oil seeps into the crankshaft connecting hole 2 and the contact surface of the crankshaft head 12, thereby improving the lubrication effect between the crankshaft head 12 and the crankshaft connecting hole 2 and reducing wear.

[0029] Due to the existence of the first groove body 3, when the crankshaft head 12 and the crankshaft connecting hole 2 rotate relative to each other, the first groove body 3 will rotate circumferentially relative to the outer surface of the crankshaft head 12, thereby collecting the oil on the outer surface of the crankshaft head 12 in the first groove body 3, and as the crankshaft connecting hole 2 and the crankshaft head 12 continue to rotate, the oil in the first groove body 3 will gradually increase and flow toward the two ends of the first groove body 3, thereby quickly increasing the oil area between the crankshaft connecting hole 2 and the crankshaft head 12, that is, the excess oil transported from the crankshaft head 12 will be collected in the first groove body 3, and since the lower end of the first groove body 3 extends to the end face of the crankshaft connecting hole 2, that is, the lower end of the first groove body 3 is in a through state, excess liquid will seep out from the lower end of the first groove body 3 and fall on the surface of the crankshaft 13, so that a stable thickness of oil film can be formed between the crankshaft head 12 and the crankshaft connecting hole 2. In addition, since the upper part of the first groove body 3 is located inside the crankshaft connecting hole 2, when the crankshaft connecting hole 2 and the crankshaft head 12 are connected, the upper part of the first groove body 3 is in a closed state. When the oil enters the first groove body 3, a certain vacuum degree can be generated inside the first groove body 3 to ensure that the oil can be stored in the first groove body 3. When the crankshaft 13 moves, an oil film can be quickly formed between the crankshaft head 12 and the crankshaft connecting hole 2, thereby greatly improving the performance of the compressor.

[0030] like Figures 1 to 3As shown, a second groove body 6 is provided in the piston connection hole 5. Similarly, the second groove body 6 is arranged in the vertical direction, that is, the second groove body 6 is arranged axially along the piston connection hole 5, and the two ends of the second groove body 6 penetrate the two ends of the piston connection hole 5. When the oil passage 8 on the connecting rod 7 is aligned with the oil hole in the piston 14, the oil is transported from the crankshaft end 1 to the piston of the piston end 4 through the oil passage 8. When the oil passage 8 on the connecting rod 7 and the oil hole in the piston 14 are staggered, the oil will adhere to the contact surface between the piston connection hole 5 and the piston 14, thereby improving the lubrication effect between the piston 14 and the piston connection hole 5 and reducing wear. The second groove body 6 can also collect the oil on the contact surface between the piston 14 and the piston connection hole 5, and the oil moves toward the two ends of the second groove body 6, quickly diffuses and increases the lubricating oil liquid level between the piston 14 and the piston connection hole 5, and the excess oil can also seep out from both sides of the second groove body 6 and flow to other structures inside the compressor, thereby improving the performance of the compressor.

[0031] like Figure 4 As shown, the crankshaft end 1 is sleeved on the outside of the crankshaft head 12, and the lower surface of the crankshaft end 1 is separated from the crankshaft 13; the piston end 4 is sleeved on the connecting column inside the piston 14, and the lower surface of the piston end 4 is in contact with the base inside the piston 14, so that the installation stability of the connecting rod 7 can be ensured. At the crankshaft end 1 position, there will be no friction and wear between the lower surface of the crankshaft end 1 and the crankshaft 13. An expansion groove 9 is provided on the lower surface of the crankshaft end 1, and the expansion groove 9 is flush with or connected to the lower end of the first slot body 3. On the one hand, the expansion groove 9 can reduce the contact area between the crankshaft connecting hole 2 and the crankshaft head 12, reducing the rotational friction and wear between the two, and on the other hand, it can quickly guide the excess oil inside the first slot body 3 to the surface of the crankshaft 13. At the piston end 4 position, the lower surface of the piston end 4 abuts against the inside of the piston 14, which will generate rotational friction. Therefore, an oil groove 10 is provided on the lower surface of the piston end 4, as shown in FIG. Figure 2 As shown, the oil groove 10 is arranged in an annular manner on the lower surface of the piston end 4, thereby reducing the contact area between the lower surface of the piston end 4 and the piston 14, and reducing rotational wear. In addition, the oil groove 10 on the lower surface of the piston end 4 is also connected to the second groove body 6, so that the oil inside the second groove body 6 can be guided into the oil groove 10, increasing the amount of oil between the lower surface of the piston end 4 and the piston 14, improving the lubrication effect between the two and reducing wear.

[0032] It should also be noted that in this solution, the first slot body 3 and the second slot body 6 are arranged staggered with the position of the oil passage 8. Specifically, the first slot body 3 located inside the crankshaft connecting hole 2 is staggered with the oil passage 8. When the oil hole on the crankshaft head 12 is aligned with the oil passage 8, the oil inside the crankshaft head 12 will only be transported to the inside of the oil passage, and when the oil hole on the crankshaft head 12 is staggered with the oil passage 8, the oil hole on the crankshaft head 12 will contact the inner surface of the crankshaft connecting hole 2, so that part of the oil will adhere to the inner surface of the crankshaft connecting hole 2 or the first slot body 3, so as to avoid the first slot body 3 affecting the oil delivery efficiency of the connecting rod 7. If the positions of the first slot body 3 and the oil passage 8 are arranged correspondingly, when the oil hole on the crankshaft head 12 delivers oil to the oil passage 8, part of the oil will be delivered to the first slot body 3 and seep to the outside, reducing the oil delivery efficiency. Therefore, it is necessary to stagger the first slot body 3 and the oil passage 8. Similarly, the second tank body 6 also needs to be staggered with the oil passage 8 . The principle is consistent with the design concept of the first tank body 3 , which will not be elaborated here.

[0033] A reinforcement part 11 is provided at the connection between the connecting rod 7 and the crankshaft end 1, and at the connection between the connecting rod 7 and the piston end 4. The reinforcement part 11 is a thickened structure, which is equivalent to a rib-like structure, and increases the effective connection area between the connecting rod 7 and the outer surface of the crankshaft end 1, and the outer surface of the piston end 4, thereby enhancing the connection strength. Similarly, in order to improve the strength and quality between the connecting rod 7, the crankshaft end 1, and the piston end 4, the connecting rod 7, the crankshaft end 1, and the piston end 4 are also blackened during the actual production process.
