In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a piston that has piston ring stop gear, includes the piston head, the piston head includes top, head and skirt portion, just gas ring groove and oil ring groove have been seted up to head exterior wall, the piston is still including:
the piston ring comprises a piston gas ring and a piston oil ring, the outer surface wall of the piston gas ring and the outer surface wall of the piston oil ring are both provided with insertion holes, and the piston gas ring and the piston oil ring are respectively sleeved on the inner surfaces of the gas ring groove and the oil ring groove.
As a further description of the above technical solution:
the piston gas ring and the piston oil ring are both provided with openings.
As a further description of the above technical solution:
and a piston pin hole is formed at the vertical end of the skirt part.
As a further description of the above technical solution:
the convex blocks are distributed annularly.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
the utility model discloses in, fixed mounting has the protruding piece in the recess of installation piston gas ring and piston oil ring, when installation piston gas ring and piston oil ring, cup joints piston gas ring and piston oil ring in the recess to with the jack correspondence protruding piece on piston gas ring and the piston oil ring, the block is connected, has effectively prevented the unexpected rotation of piston ring, has improved the result of use of piston.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides a piston that has piston ring stop gear, includes piston head 1, and piston head 1 includes top 101, head 102 and skirt portion 103, and head 102 outward appearance wall has seted up gas ring groove 2 and oil ring groove 4, and the piston still includes:
protruding piece 3 and piston ring, protruding piece 3 fixed mounting are at the outer table wall of gas ring groove 2 and oil ring groove 4, and the piston ring includes piston gas ring 6 and piston oil ring 9, and jack 7 has all been seted up to piston gas ring 6 and the outer table wall of piston oil ring 9 for be connected with protruding piece 3 block, and piston gas ring 6 cup joints respectively at gas ring groove 2 and oil ring groove 4 internal surface with piston oil ring 9.
Specifically, as shown in fig. 3, the piston gas ring 6 and the piston oil ring 9 are both provided with openings 8, so that the piston ring is prevented from clamping the cylinder wall or breaking when expanding due to high temperature.
Specifically, as shown in fig. 1, a piston pin hole 5 is formed at the vertical end of the skirt portion 103 to realize connection with a connecting rod.
Specifically, as shown in fig. 1, the protruding blocks 3 are annularly arranged and are not in the same direction as the piston pin hole 5, thereby improving the sealing performance of the piston.
The working principle is as follows: during the use, at the recess internal fixation who installs piston gas ring 6 and piston oil ring 9 and installed protruding piece 3, when installation piston gas ring 6 and piston oil ring 9, cup joint piston gas ring 6 and piston oil ring 9 in the recess to with the jack 7 correspondence protruding piece 3 on piston gas ring 6 and the piston oil ring 9, the block is connected, has effectively prevented the unexpected rotation of piston ring, has improved the result of use of piston.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
