In a preferred embodiment of the present invention, the stopper can extend out of the second circular hole through the resilience of the spring.

The utility model has the advantages that: the utility model discloses a components of a whole that can function independently piston ring, fall into main piston ring and vice piston ring with the piston ring, conveniently maintain the change when the piston ring is local to carry on spacingly to main piston ring and vice piston ring through stop gear, thereby effect when can reaching better sealing has avoided the situation that the piston ring appears leaking when sealed.

Drawings

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained without inventive work, wherein:

fig. 1 is a schematic structural view of a preferred embodiment of a split piston ring according to the present invention;

FIG. 2 is an enlarged view of portion A of FIG. 1;

fig. 3 is an assembly view of a split piston ring according to the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, an embodiment of the present invention includes:

a split piston ring, comprising: the combined piston ring comprises a main piston ring 1 and an auxiliary piston ring 2, wherein at least 2 limiting mechanisms 3 are arranged on the auxiliary piston ring 2, the main piston ring 1 and the auxiliary piston ring 2 are both of hollow ring structures, the section of the main piston ring 1 is of a concave structure, and the section of the auxiliary piston ring 2 is of a T-shaped structure.

The auxiliary piston ring 2 with the T-shaped section is inserted into the main piston ring 1 with the concave section.

The limiting mechanism 3 comprises: stopper 31, slide 32, spring 33, first round hole 34 and second round hole 35, set up the first round hole 34 and the second round hole 35 that are linked together on the vice piston ring 2, second round hole 35 sets up in one side of first round hole 34, the one end fixed connection of spring 33 is in the bottom surface of first round hole 34, the other end and the slide 32 fixed connection of spring 33, slide 32 slides in first round hole 34, stopper 31 is fixed to be set up on the surface of slide 32, set up on the main piston ring 1 and supply stopper 31 male spacing groove 4.
