Abstract
The utility model provides a seal ring which comprises a seal ring body and an embedded point arranged on the inner wall of the seal ring body and matched with a seal groove in embedded mode. The cross section of the seal ring body is of an H shape. The seal ring comprises the seal ring body and the embedded point, and the cross section of the seal ring body is of the H shape. Compared with a conventional O-shaped seal ring, the H-shaped seal ring has two seal faces, large seal area and more reliable seal performance. Therefore, the sealing effect of the seal ring is improved. As the embedded point of the seal ring is embedded in the seal groove, the seal ring can be fastened more stably with a sealed piece.
Description
Technical field
The utility model relates to the motor technical field of sealing technology, more particularly, relates to preferably seal ring of a kind of sealing effect.
Background technique
Current oil in engine road and the sealing means in water route, generally all adopt O-ring seals, because O-ring seals is with little by the area of contact of Sealing, resiliently deformable is little, in machine oil and the large sealing position of coolant pressure, the easy compressed distortion of O-ring seals, and then cause sealing effect poor, and traditional O-ring seals and by Sealing in conjunction with insecure, drop easily when mounted, affect installation efficiency.
Therefore, how to provide a kind of sealing effect better, and with by the combination of Sealing seal ring more firmly, be present those skilled in the art's problem demanding prompt solution.
The model utility content
In view of this, the utility model provides a kind of seal ring, with solve existing O-ring seals sealing effect poor and be combined unstable problem by Sealing.
In order to achieve the above object, the utility model provides following technological scheme:
A kind of seal ring comprises the seal ring body and is arranged on the described seal ring inner body wall, is used for the embedding point that cooperates with the seal groove setting-in; The shape of cross section of described seal ring body is the H type.
Preferably, in the above-mentioned seal ring, described embedding point is a plurality of, and is evenly distributed on the inwall of described seal ring body.
Preferably, in the above-mentioned seal ring, described embedding point is integrated the molding and forming structure with described seal ring body.
Preferably, in the above-mentioned seal ring, described embedding point is the taper type structure.
Preferably, in the above-mentioned seal ring, the end that described embedding point cross-section area is less has the fillet that radius is 0.5mm.
Preferably, in the above-mentioned seal ring, to the free end convergent, the angle between its end face and the bottom surface is 80 ° to described embedding point from its connecting end that links to each other with the inwall of described seal ring body, about angle between two sides be 60 °.
The seal ring that the utility model provides comprises seal ring body and embedding point, and the shape of cross section of seal ring body is the H type, with respect to traditional O-ring seals, have two sealing surfaces, the area of sealing is large, seals more reliably, has improved the sealing effect of seal ring, simultaneously the embedding point of the seal ring that provides of the utility model for and the seal groove setting-in so that its be connected by Sealing more firm.
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 the utility model 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.
The structural representation of the seal ring that Fig. 1 provides for the utility model embodiment;
Fig. 2 be among Fig. 1 A-A to sectional view;
Fig. 3 is the structure for amplifying schematic representation of B part among Fig. 1.
Among upper Fig. 1-3:
Embodiment
The utility model embodiment provides a kind of seal ring, solved existing O-ring seals sealing effect poor and be combined unstable problem by Sealing.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is a part of embodiment of the present utility model, rather than whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work belongs to the scope that the utility model is protected.
Please refer to Fig. 1, the utility model embodiment provides a kind of seal ring, comprises seal ring body 1, and it is as the agent structure of whole seal ring, and shape of cross section is the H type, and it has two faces that are sealed and matched;
With the embedding point 2 that is arranged on the seal ring body 1, it is used for and is cooperated by the seal groove setting-in on the Sealing.
The seal ring that the utility model embodiment provides improves existing seal ring, comprise seal ring body 1 and embedding point 2, and the shape of cross section of seal ring body 1 is the H type, with respect to traditional O-ring seals, have two sealing surfaces, the area of sealing is large, seal more reliable, improved the sealing effect of seal ring, be provided with embedding point 2 on the seal body 1 of the seal ring that the while present embodiment provides, embedding point 2 is used for and is cooperated by the seal groove setting-in of Sealing so that whole seal ring with by being connected of Sealing more firm.
For so that whole seal ring be connected more firmly by Sealing, firmly effect is better, above-mentioned embedding point 2 is a plurality of, and is evenly distributed on the inwall of seal ring body 1.
According to traditional technique, in the seal ring that the utility model embodiment provides, embedding point 2 and seal ring body 1 are integrated the molding and forming structure.
Particularly, the embedding point 2 on the above-mentioned seal ring can be the taper type structure.Preferably, above-mentioned embedding is put the less end of 2 cross-section areas and is had the fillet that radius is 0.5mm.Certainly concrete, oneself connecting end of linking to each other with the inwall of seal ring body 1 of above-mentioned embedding point 2 please refer to Fig. 2-3 to the free end convergent, and the end face of embedding point 2 and the angle between the bottom surface are 80 °, about two sides between angle be 60 °.Certain above-mentioned embedding point 2 can also be other shape and structure, is not limited to above-mentioned structure.
To the above-mentioned explanation of the disclosed embodiments, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be apparent concerning those skilled in the art, and General Principle as defined herein can in the situation that does not break away from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
