Description
Technical Field
The utility model relates to a sealing member technical field, more specifically the utility model relates to an oil cylinder sealing ring that says so.
Background
Most of existing sealing products are elastic annular structures which are integrally formed, the sealing products mainly fill gaps between pistons and hydraulic cylinder bodies, and the sealing between the hydraulic cylinders and the pistons is achieved by deformation caused by compression of the pistons and the cylinder bodies. Because the extrusion force that the sealing washer received is too big in the operation process, and is in the deformation state for a long time, leads to the sealing washer to be easy to be because of the too big wearing and tearing of frictional force and lose elasticity, influences sealed effect.
Therefore, it is an urgent need to solve the problem of the art to provide a cylinder seal ring, which improves the wear resistance and pressure resistance of the seal ring and maintains the elasticity thereof to prolong the service life of the seal ring.
SUMMERY OF THE UTILITY MODEL
The utility model discloses aim at solving one of the above-mentioned technical problem among the prior art to a certain extent at least, provide an oil cylinder sealing washer.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
an oil cylinder sealing ring, comprising: the inner side of the upper end face of the flexible sealing ring body is provided with a groove for embedding a check ring, and the lower end face of the flexible sealing ring body is provided with a ring groove for embedding a metal sealing ring.
Furthermore, the section of the retainer ring is rectangular, and the section of the metal sealing ring is trapezoidal.
Furthermore, the retainer ring is made of rubber.
According to the technical scheme, compared with the prior art, the utility model discloses an oil cylinder sealing ring, the upper end face and the lower end face are respectively embedded with a rubber retaining ring and a metal sealing ring, and the structure is arranged in an oil cylinder machine, so that the sealing property and the pressure resistance of the oil cylinder can be greatly enhanced;
by the aid of the reinforcing structure of the metal sealing ring, friction force of the sealing ring on the piston rod of the oil cylinder is reduced on the premise that the sealing effect of the sealing ring is not weakened, and the service life is prolonged;
and the installation or replacement of the oil cylinder is convenient for workers, the sealing effect of the oil cylinder is ensured, and the inside and the outside of the oil cylinder are well separated.

Fig. 2 is a sectional view of the flexible sealing ring body of the present invention.
Fig. 3 is a sectional view of the oil cylinder sealing ring of the present invention.
Wherein:
1-a flexible sealing ring body; 2-a retainer ring; 3-a metal seal ring; 11-a groove; 12-ring groove.
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 in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
The embodiment of the utility model discloses oil cylinder sealing ring, include: the inner side of the upper end face of the flexible sealing ring body 1 is provided with a groove 11 for embedding the check ring 2, and the lower end face of the flexible sealing ring body 1 is provided with a ring groove 12 for embedding the metal sealing ring 3; the section of the retainer ring 2 is rectangular, the section of the metal sealing ring 3 is trapezoidal, and the material of the retainer ring 2 is rubber.
The check ring is arranged on the end face close to the flexible sealing ring body, which bears the positive pressure of oil, and is embedded in the groove on the flexible sealing ring body, compared with the existing integrally-formed annular sealing ring, the check ring can block the gap between the piston rod and the hydraulic cylinder body on the premise of not weakening the sealing effect, and the integrally-formed sealing ring in the prior art has larger elastic coefficient, so that once the gap is blocked by deformation generated by lateral compression, the elastic pressure of the sealing ring on the piston rod is relatively larger at the moment, and the friction force generated on the piston rod is also larger; and the utility model discloses a paste tight piston rod, the annular provides the space of deformation buffering and motion buffering, and consequently, the radial elastic pressure that the sealing washer was applyed to the piston rod diminishes, and consequently the frictional force that produces between piston rod and the sealing member then diminishes, establishes but metal seal ring additional strengthening through further inlaying, improves leakproofness and crushing resistance.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other. The device disclosed by the embodiment corresponds to the method disclosed by the embodiment, so that the description is simple, and the relevant points can be referred to the method part for description.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
