Description

Technical Field

[0001] The utility model relates to the technical field of cylinder maintenance, in particular to a quick installation tool for a cylinder piston ring. Background Art

[0002] The piston ring is a metal ring that is embedded in the piston groove. There are two types of piston rings: compression rings and oil rings. The compression ring can be used to seal the combustible mixture in the combustion chamber; the oil ring is used to scrape off the excess oil on the cylinder. Piston rings generally have a service life. If the piston ring is excessively worn or damaged, it will cause various engine failures and need to be replaced in time. Be extra careful when installing the piston ring. If it is not installed properly, it will also affect the engine performance.

[0003] The utility model patent with patent application publication number CN 219685432 U discloses a cylinder piston ring quick installation tool, including a guide ring, the outer wall of the guide ring is a closed cylindrical shape, the inner wall of the guide ring is provided with a cylindrical area and a conical surface, one side of the guide ring is provided with an opening, and the outer wall of the guide ring is provided with a tightening member for tightening the guide ring. The utility model discloses a cylinder piston ring quick installation tool, the guide ring has an opening, so that the inner diameter of the guide ring can be adjusted and fixed by the tightening member, so that the inner diameter of the guide ring can be maintained, the operation is convenient, and it is easy to adapt to pistons of various outer diameters, and it has good universality. The tightening member provided provides an anti-slip point, which has the technical effect of facilitating people to hold the guide ring.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that when using the device, it is first necessary to use a tightening piece to adjust the size of the guide ring so that the piston ring and the guide ring are fitted together, and then the tightening piece is fixed before the piston ring is installed. It is very troublesome to use. During actual installation, the fit between the inner wall of the guide ring and the outer side of the piston ring will generate a large friction force, causing the piston ring to fall slowly, wasting a lot of time and reducing the installation efficiency of the operator. In addition, the device is fixed by a tightening piece, which is easy to cause irreversible deformation of the guide ring under long-term use, thereby reducing the service life of the guide ring.

[0005] Therefore, it is necessary to invent a cylinder piston ring quick installation tool to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a cylinder piston ring quick installation tool. By setting an adjustment mechanism, the problem proposed in the above background technology that the device needs to use a tightening piece to adjust the size of the guide ring when in use, so that the piston ring and the guide ring are fitted together and then the tightening piece is fixed before the piston ring is installed is solved. It is very troublesome to use. During actual installation, due to the large friction force generated by the fit between the inner wall of the guide ring and the outer side of the piston ring, the piston ring falls slowly, which wastes a lot of time and reduces the installation efficiency of the operator.
