Description

Technical Field

[0001] This utility model relates to the field of compressor connecting rod technology, and in particular to a compressor connecting rod with a self-lubricating coating. Background Technology

[0002] The connecting rod is a key component of the compressor. Its main function is to transfer the thrust of the refrigerant vapor acting on the piston to the crankshaft, and to convert the rotational motion of the crankshaft into the reciprocating motion of the piston, thereby doing work on the refrigerant vapor. The connecting rod consists of a rod body, a big end, and a small end. The big end is connected to the crankshaft, and the small end is connected to the piston.

[0003] The prior art utility model patent with publication number CN212615865U discloses a compressor connecting rod, which has oil passages connected to an oil storage mechanism at the big end, rod part and small end of the connecting rod, and ball grooves at the big end and small end of the connecting rod, each ball groove being connected to the oil passage. Lubricating oil can be applied to each ball through the oil passage, thereby lubricating the big end and small end of the connecting rod.

[0004] However, its lubrication operation is relatively troublesome. During use, lubricating oil needs to be added to the inside of the connecting rod regularly, and the compressor needs to be disassembled frequently, which increases the manpower, material and time costs of maintenance. It can also easily lead to problems such as the compressor becoming loose. The addition of lubrication channels and ball bearings can also affect the entire connecting rod, which can easily cause abnormal noise and bending. Therefore, we need to upgrade and modify the existing technology to overcome the existing problems and shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide a compressor connecting rod with a self-lubricating coating to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Design a compressor connecting rod with a self-lubricating coating, including a device body. The device body includes a connecting rod, a lower retainer, a lubrication component, and a hollow component. The connecting rod has side reinforcing ribs and main reinforcing ribs on its sides and surface, respectively. The lower retainer is fixed to the top of the connecting rod, and a connecting rod small end is fixed to the bottom of the connecting rod. An upper retainer is fixed to the upper end of the lower retainer. Limiting grooves are provided on the inner sides of the lower and upper retainers, and the lubrication component is disposed in the limiting grooves. The hollow component is disposed inside the connecting rod.

[0008] The lubrication assembly includes an inner ring body installed in a limiting groove, with a graphite layer disposed on the inner side of the inner ring body, and through holes corresponding to the lower ends of the inner ring body and the graphite layer.

[0009] Preferably, the hollow component includes a hollow groove formed inside the connecting rod, and a right locking block and a left locking block are provided in the hollow groove.

[0010] Preferably, the right and left card blocks are provided in several groups, and the right and left card blocks are staggered on both sides of the hollow groove, and through holes are opened on the right and left card blocks respectively.

[0011] Preferably, the lower card seat has an upper opening at its center, the top of the hollow groove corresponds to the upper opening and the through hole, the small end of the connecting rod is provided with a wear-resistant ring, and the small end of the connecting rod and the wear-resistant ring have a lower opening at their center, the lower opening corresponding to the bottom of the hollow groove.

[0012] Preferably, sealing edges are provided on both sides of the inner ring body, and the sealing edges are attached to the outside of the limiting groove.

[0013] Preferably, the lower card holder and the upper card holder are provided with corresponding connecting holes on both sides and the bottom of the connecting holes are provided with embedded grooves. A connecting bolt is screwed into the connecting hole and the end of the connecting bolt is located in the embedded groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model features a device with a lower mounting base, an upper mounting base, a limiting groove, a connecting hole, a connecting bolt, an inner ring body, a sealing edge, a graphite layer, and a through hole. The inner ring body is positioned and installed using the limiting groove, ensuring that the sealing edges on both sides are tightly fitted to the outside of the limiting groove. The two sets of mounting bases are fixed using the connecting hole and the connecting bolt, thereby enabling self-lubrication of one end of the connecting rod. This reduces friction between the connecting rod and other components, eliminates the need for manual lubrication, and allows the inner ring body to be independently disassembled and replaced. This significantly reduces the manpower, material resources, and time costs of maintenance, and improves the practicality of the device.

[0016] This invention features a connecting rod, side reinforcing ribs, main reinforcing ribs, a hollow component, a hollow groove, a right locking block, a left locking block, and a through hole. The hollow groove makes the interior of the connecting rod hollow, and the right and left locking blocks reinforce the interior of the hollow groove, thereby significantly reducing the weight of the connecting rod. Despite the action of multiple locking blocks, it maintains sufficient strength and rigidity, which is beneficial for heat dissipation. Especially under high-load working conditions, it improves the service life of the connecting rod.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 As shown in Figure 4, this embodiment provides a compressor connecting rod with a self-lubricating coating, including a device body 1. The device body 1 includes a connecting rod 2, a lower retainer 3, a lubrication component 5, and a hollow component 6. The connecting rod 2 has side reinforcing ribs 21 and main reinforcing ribs 22 on its two sides and surface, respectively. The lower retainer 3 is fixed to the top of the connecting rod 2, and the connecting rod small end 4 is fixed to the bottom of the connecting rod 2. The upper retainer 31 is fixed to the upper end of the lower retainer 3. The lower retainer 3 and the upper retainer 31 are respectively provided with limiting grooves 33 on their inner sides. The lubrication component 5 is disposed in the limiting grooves 33, and the hollow component 6 is disposed inside the connecting rod 2.

[0026] In this embodiment, the lubrication assembly 5 includes an inner ring body 51 installed in the limiting groove 33. A graphite layer 53 is provided on the inner side of the inner ring body 51. A through hole 54 is provided at the lower end of the inner ring body 51 and the graphite layer 53 respectively. Sealing edges 52 are provided on both sides of the inner ring body 51 and are attached to the outer side of the limiting groove 33. Connecting holes 32 are provided on both sides of the lower card seat 3 and the upper card seat 31 respectively, and an embedded groove 321 is provided at the bottom of the connecting hole 32. A connecting bolt 7 is screwed into the connecting hole 32 and the end of the connecting bolt 7 is located in the embedded groove 321. Within 21, the inner ring body 51 is limited and installed by the limiting groove 33, so that the sealing edges 52 on both sides are sealed and fitted to the outside of the limiting groove 33. The two sets of card seats are fixed by the connecting hole 32 and the connecting bolt 7. The graphite layer 53 is attached to the external equipment, thereby realizing the self-lubricating operation of one end of the connecting rod, reducing the friction between the connecting rod and other parts, eliminating the need for manual addition of lubricating oil, and the inner ring body 51 can be disassembled and replaced independently, greatly reducing the manpower, material and time costs of maintenance, and improving the practicality of the device.

[0027] In this embodiment, the hollow component 6 includes a hollow groove 61 formed inside the connecting rod 2. A right locking block 62 and a left locking block 63 are provided within the hollow groove 61. Several sets of right locking blocks 62 and left locking blocks 63 are provided. The right locking blocks 62 and left locking blocks 63 are staggered on both sides of the hollow groove 61, and through holes 64 are respectively provided on the right locking blocks 62 and left locking blocks 63. An upper opening 34 is provided at the center of the lower locking seat 3. The top of the hollow groove 61 corresponds to the upper opening 34 and the through hole 54. A wear-resistant ring 41 is provided inside the small end 4 of the connecting rod, and a lower opening 42 is provided at the center of the small end 4 of the connecting rod and the wear-resistant ring 41. 42 corresponds to the bottom of the hollow groove 61. The hollow groove 61 makes the interior of the connecting rod 2 hollow. The right locking block 62 and the left locking block 63 reinforce the interior of the hollow groove 61 to prevent bending or breakage. The upper and lower structures are connected to the hollow groove 61 through the upper opening 34 and the lower opening 42, which significantly reduces the weight of the connecting rod. This is very helpful in reducing the overall weight of the compressor. Under the action of multiple sets of locking blocks, it can still maintain sufficient strength and rigidity, which is conducive to heat dissipation, especially under high load conditions, thus improving the service life of the connecting rod.

[0028] The working principle and process of this utility model are as follows: In use, the inner ring body 51 can be installed in the limiting groove 33 between the lower card seat 3 and the upper card seat 31, so that the sealing edges 52 on both sides are sealed and fitted to the outside of the limiting groove 33. The two sets of card seats can be fixed by connecting holes 32 and connecting bolts 7. The graphite layer 53 is connected to the piston shaft, which can achieve effective self-lubrication operation, reduce the friction between the connecting rod and other parts, and eliminate the need for manual addition of lubricating oil. When the graphite layer 53 or the inner ring body 51 is damaged, it can be disassembled and replaced independently. Through the cooperation of the hollow groove 61 and the card blocks, the weight of the connecting rod can be significantly reduced. Under the action of multiple sets of card blocks, it can still maintain sufficient strength and hardness and facilitate heat dissipation.
