Description

Technical Field

[0001] This utility model belongs to the field of gas compressor connecting rod technology, specifically relating to a quick-assembly and disassembly gas compressor connecting rod connection mechanism. Background Technology

[0002] A gas compressor is a power device that converts mechanical energy into gas pressure energy. It is often used in pneumatic tools to provide gas power. The connecting rod of a gas compressor is a key component that connects the piston and the crankshaft. It is responsible for converting the rotational motion of the crankshaft into the reciprocating motion of the piston, thereby driving the gas compression process.

[0003] The utility model patent with publication number CN220748791U in the prior art proposes a refrigerator compressor connecting rod. The device uses fastening bolts to fix the first half ring and the second half ring by screwing the fastening bolts into the inside of the first connecting post and the second connecting post. When the second half ring is worn, it only needs to be replaced, and the entire connecting rod will not be scrapped.

[0004] However, in actual use, the bolts and nuts are simply connected by threads, resulting in an unstable connection structure. When the bolts loosen or the threads strip, the nuts can easily detach from the connecting rod bolts. Therefore, we need to upgrade and modify the existing technology. Utility Model Content

[0005] The purpose of this invention is to provide a quick-release gas compressor connecting rod connection mechanism to solve the problems mentioned in the background art.

[0006] To solve the above problems, the following technical solutions are provided:

[0007] A quick-assembly and disassembly gas compressor connecting rod connection mechanism is designed, including a device body.

A piston pin is provided inside the piston ring. A lower connecting rod bearing is provided at one end of the upper connecting rod bearing. The upper and lower connecting rod bearings are provided with a first insertion hole and a second insertion hole. A first bolt is inserted into the first insertion hole and a second bolt is inserted into the second insertion hole. A nut is screwed onto the first and second bolts, and a pin hole and an oil injection hole are provided inside the first and second bolts. A threaded pin is inserted into the pin hole, and a nut is screwed onto the threaded pin. A groove is provided in the oil injection hole.

[0010] Furthermore, both bolt one and bolt two are fitted with washers, and the washers are movably connected to bolt one and bolt two.

[0011] Furthermore, an anti-slip groove is provided on the outer wall of the first nut, and an anti-slip strip is fixedly provided on the outer wall of the second nut.

[0012] Furthermore, the threaded pin is a split snap-fit ​​design, with a clamping plate fixedly mounted on the threaded pin. Anti-slip pads are fixedly mounted on the inner wall of the clamping plate, and the anti-slip pads are in close contact with the outer wall of the nut.

[0013] Furthermore, a sealing plug is provided inside the card slot, and the sealing plug is sealed and engaged with the card slot.

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

[0025] 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.

[0026] like Figure 1 As shown in Figure 5, this embodiment provides a quick-release gas compressor connecting rod connection mechanism, including a device body 1. The device body 1 contains a connecting rod 2. The front end of the connecting rod 2 is connected to a piston ring 3, and the rear end of the connecting rod 2 is connected to a connecting rod upper bearing 6. A piston pin 5 is provided in the piston ring 3. A connecting rod lower bearing 7 is provided at one end of the connecting rod upper bearing 6. The connecting rod upper bearing 6 and the connecting rod lower bearing 7 are provided with a first insertion hole 9 and a second insertion hole 10. A first bolt 11 is inserted into the first insertion hole 9, and a second bolt 12 is inserted into the second insertion hole 10. A first nut 14 is screwed onto the first bolt 11 and the second bolt 12. A pin hole 16 and an oil injection hole 22 are provided in the first bolt 11 and the second bolt 12. A threaded pin 17 is inserted into the pin hole 16, and a second nut 20 is screwed onto the threaded pin 17. A groove 23 is provided in the oil injection hole 22.

[0027] Preferably, the piston ring 3 is provided with an anti-wear sleeve 4, and a piston pin 5 is movably installed in the anti-wear sleeve 4. The anti-wear sleeve 4 is fixedly connected to the piston ring 3. By providing the anti-wear sleeve 4, the piston ring 3 can be protected, and wear between the piston pin 5 and the piston ring 3 can be avoided, thus affecting the subsequent use of the device. The upper bearing 6 and the lower bearing 7 of the connecting rod are provided with sealing rings 8, which are movably engaged with the upper bearing 6 and the lower bearing 7 of the connecting rod. By providing the sealing rings 8, the device can be sealed and protected, ensuring the safety of the device during use.

[0028] Preferably, both bolt 11 and bolt 12 are fitted with washers 13, which are movably connected to bolt 11 and bolt 12. By setting washers 13, wear on the surface of the lower bearing 7 of the connecting rod is avoided during the pre-tightening process of nut 14, thus extending the service life of the device. Anti-slip grooves 15 are provided on the outer wall of nut 14, and anti-slip strips 21 are fixedly provided on the outer wall of nut 20. By setting anti-slip grooves 15 and anti-slip strips 21, the user is prevented from slipping or having difficulty turning nut 14 and nut 20, thus providing convenience for the user.

[0029] Preferably, the threaded pin 17 is a split snap-fit ​​design, with a clamping plate 18 fixedly mounted on it. Anti-slip pads 19 are fixedly mounted on the inner wall of the clamping plate 18, and these pads 19 are in close contact with the outer wall of the nut 14. This allows the user to easily disassemble and reassemble the threaded pin 17, improving the flexibility of the device. The clamping plate 18 limits and fixes the nut 14, while the anti-slip pads 19 prevent slippage during use. A sealing plug 24 is provided in the slot 23, sealingly engaging with it. This sealing plug 24 protects the oil filling hole 22, reducing oil leakage and preventing dust accumulation that could affect subsequent use of the device.

[0030] The working principle and process of this utility model are as follows: In use, the piston ring 3 of connecting rod 2 is connected to the piston pin 5 via the anti-wear sleeve 4. Connecting rod 2 is then installed on the crank pin of the air compressor crankshaft via the upper connecting rod bearing 6 and the lower connecting rod bearing 7. Bolt 11 and bolt 12 are then inserted into the insertion holes 9 and 10 respectively, and nut 14 is screwed onto bolts 11 and 12, thus connecting connecting rod 2. This facilitates quick disassembly of the device later. When the bolts need to be prevented from loosening during use, the user inserts threaded pins 17 through the pin holes 16 into bolts 11 and 12 respectively. (Threaded pins 17 are of a split structure, with two sets symmetrically arranged; the threaded pins 17 can be separated and movably engaged) until the anti-slip pad 19 of the clamping plate 18 is engaged with bolts 11 and 12. The outer wall can be tightly fitted to limit and fix the bolts of the device, increasing the stability of the bolts, ensuring the safety of the bolts during use, and preventing the bolts from loosening and falling off during use. When the bolts of the device oxidize and rust after long-term use, the user can pull them out of the slot 23 through the sealing plug 24, and pour lubricating oil into the oil injection hole 22. The lubricating oil enters the thread groove of the bolt through the oil injection hole 22, thereby lubricating the bolt. It can deliver the lubricating oil to the thread contact surface, reduce the friction coefficient between the bolt and nut, reduce wear and extend service life, and facilitate the user to disassemble and fix the device later.
