Abstract
The utility model discloses a seal ring with a rotating positioning function. The seal ring with the rotating positioning function comprises a seal ring body (1) which is in a circular ring structure. An installing through hole (2) is arranged in the seal ring body (1). An anti-skidding thread (3) is arranged on the inner wall of the seal ring (1) which is close to the installing through hole (2). The anti-skidding thread (3) is composed of a plurality of concave grooves (31) which are evenly distributed on the inner wall of the installing through hole (2). According to the anti-skidding thread composed of the plurality of the concave grooves which are evenly distributed on the inner wall of the installing through hole (2), the seal ring with the rotating positioning function is capable of preventing the seal ring body from rotating when the seal ring with the rotating positioning function is stressed, and has the advantages of being capable of sealing reliably, not easy to rotate, long in service life, simple in structure and low in cost.
Description
Technical field
The utility model relates to a kind of seal ring with the rotating position function.
Background technique
Seal ring is again O-ring seals, generally is used for the sealing configuration between the metalwork.But, the seal ring of prior art, without the rotating position function, therefore easily rotating causes seal ring to be worn, and finally causes seal ring to lose efficacy.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of seal reliable, be difficult for rotation, long service life, the seal ring with the rotating position function simple in structure, with low cost.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of seal ring with the rotating position function, comprise the seal ring body that is circular ring, described seal ring body is provided with the installation through hole, described seal ring body is provided with anti-slip veins by the inwall that through hole is installed, and described anti-slip veins is comprised of a plurality of grooves on the inwall that is uniformly distributed in described installation through hole.
As further improvement in the technical proposal:
Described a plurality of groove is arranged along the axial direction of described installation through hole respectively.
Described seal ring body is provided with the sealed extruded ring that tilts to stretch out to the axis that through hole is installed by the end that through hole is installed.
The utlity model has following advantage:
The utility model comprises the seal ring body that is circular ring, the seal ring body is provided with the installation through hole, the seal ring body is provided with anti-slip veins by the inwall that through hole is installed, anti-slip veins is comprised of a plurality of grooves on the inwall that is uniformly distributed in described installation through hole, the utility model can prevent that by the anti-slip veins that a plurality of grooves on the inwall that is uniformly distributed in described installation through hole consist of the seal ring body from rotating when stressed, have advantages of that sealing is reliable, be difficult for rotation, long service life, simple in structure, with low cost.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model embodiment's perspective view.
Fig. 2 is the utility model embodiment's plan structure schematic diagram.
Fig. 3 is the utility model embodiment's side-looking structural representation.
Marginal data: 1, seal ring body; 2, through hole is installed; 3, anti-slip veins; 31, groove; 4, sealed extruded ring.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention are made more explicit defining.
Such as Fig. 1, Fig. 2 and shown in Figure 3, the present embodiment comprises the seal ring body 1 that is circular ring with the seal ring of rotating position function, seal ring body 1 is provided with installs through hole 2, seal ring body 1 is provided with anti-slip veins 3 by the inwall that through hole 2 is installed, and anti-slip veins 3 is comprised of a plurality of grooves 31 that are uniformly distributed on the inwall that through hole 2 is installed.
In the present embodiment, along the axial direction layout that through hole 2 is installed, the frictional force that forms during rotation is larger respectively for a plurality of grooves 31, and rotating position is with better function.
In the present embodiment, seal ring body 1 is provided with the sealed extruded ring 4 that tilts to stretch out to the axis that through hole 2 is installed by the end that through hole 2 is installed, and sealed extruded ring 4 can further be adjacent to metalwork, and sealing effect is better.
The above only is preferred implementation of the present utility model, and protection domain of the present utility model is not limited in above-mentioned mode of execution, and every technological scheme that belongs to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, some improvements and modifications of under the prerequisite that does not break away from principle of the present utility model, carrying out, these improvements and modifications also should be considered as protection domain of the present utility model.
