Detailed Description
In order to make the technical problems, technical solutions and technical effects achieved by the present invention more clear, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings, and obviously, the described embodiments are only some embodiments, not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1 to 3, the present embodiment provides a seal ring 1, in which the seal ring 1 can seal a seal ring groove 100. This sealing washer 1 includes cyclic annular body 11 and sets up boss 2 on cyclic annular body 11 along radial protrusion, and boss 2 includes guiding part 21 and joint portion 22, and joint portion 22 contacts with the side of seal ring groove 100 in seal ring groove 100, and guiding part 21 sets up in one side of joint portion 22 along the axial, and guiding part 21 sets up the one side that is close to the bottom surface of seal ring groove 100 in joint portion 22 promptly, and the surface of guiding part 21 is the sphere, and the surface that joint portion 22 kept away from guiding part 21 is the plane.
The sealing ring groove 100 is effectively sealed through the annular body 11, the guide and clamping functions of the sealing ring 1 and the sealing ring groove 100 during assembly are realized through the boss 2 which is convexly arranged on the annular body 11, and meanwhile, the anti-falling function is also realized; specifically, the boss 2 has a guide portion 21 and a clamping portion 22, and the clamping portion 22 is in contact with the side surface of the sealing ring groove 100 in the sealing ring groove 100 and is used for clamping the sealing ring 1 with the sealing ring groove 100; the guide part 21 is arranged at one end of the clamping part 22 close to the bottom surface of the sealing ring groove 100, the surface of the guide part 21 is a spherical surface, when the sealing ring 1 enters the sealing ring groove 100, the guide part 21 firstly enters the sealing ring groove 100, and the spherical surface can play a role in guiding, so that the installation of the sealing ring 1 and the sealing ring groove 100 is easier; the surface that joint portion 22 kept away from guide part 21 sets up to the plane, and joint portion 22 seals in sealed annular groove 100 for planar one end and the inner wall butt of sealed annular groove 100 compare in the arc surface, make sealing washer 1 can play the anticreep effect on the direction that breaks away from sealed annular groove 100, make sealed more stable. In general, the sealing ring 1 can achieve guiding, sealing and anti-dropping effects with the sealing ring groove 100.
Specifically, the side surface of the clamping portion 22 is arranged as a cylindrical surface and is in interference fit with the seal ring groove 100. The side of interference fit's joint portion 22 and the side of sealed annular groove 100 between the contact, compare and adopt spherical arch to carry out the joint in other examples, the area of contact that cylindrical joint portion 22 enabled sealing washer 1 and sealed annular groove 100 side in this embodiment is bigger, so the joint is more firm, and then can prevent effectively to put under the assembly environment of inversion even immediately, sealing washer 1 breaks away from sealed annular groove 100, makes the joint of sealing washer 1 in sealed annular groove 100 more firm. Further, the surface of the snap-in portion 22 away from the guide portion 21 is perpendicular to the axis of the cylindrical surface, making manufacture simpler.
Preferably, the cross section of the annular body 11 is rectangular, and four corners of the rectangle are provided with round corners. The setting of fillet can make the compression ratio increase of the cyclic annular body 11 of sealing washer 1, and sealing washer 1 reaches best cooperation state with seal ring groove 100 to make sealing washer 1 have good sealed effect. Further, the height of the annular body 11 is greater than the depth of the sealing ring groove 100, so that the aspect ratio of the annular body 11 of the sealing ring 1 is improved, the compression ratio can be increased, and a better sealing effect is ensured. In other embodiments, the cross-section of the annular body 11 may also be circular, and is not limited herein.
In order to ensure the sealing effect, bosses 2 are arranged on the inner side of the annular body 11 and the outer side of the annular body 11, the bosses 2 on the inner side of the annular body 11 and the bosses 2 on the outer side of the annular body 11 are arranged in groups, and the bosses 2 on the inner side of the annular body 11 and the bosses 2 on the outer side of the annular body 11 are located on the same radial direction. During sealing, the boss 2 located inside the annular body 11 and the boss 2 located outside the annular body 11 are in interference fit with the side surface of the seal ring groove 100. When the boss 2 is arranged on the inner side and the outer side of the annular body 11, the clamping parts 22 of the boss 2 on the inner side and the outer side can be matched to realize the radial limiting of the sealing ring 1 in the sealing ring groove 100, namely, the annular body 11 and the sealing ring groove 100 are arranged just opposite to each other, so that the sealing with better effect is realized.
It is worth mentioning that: the bosses 2 arranged in groups can be arranged on the inner side of the annular body 11, and arranged on the outer side of the annular body 11; one ring body 11 may be arranged on the inner side, and two ring bodies 11 may be arranged on the outer side; two annular bodies 11 can be arranged on the inner side, and one annular body 11 is arranged on the outer side; or other different number of bosses 2 to effect sealing. The specific number of such sets of bosses 2 may be set by one skilled in the art depending on the particular sealing application. In this embodiment, the group of bosses 2 is provided with one ring-shaped body 11, and the outer side of the ring-shaped body 11 is provided with one ring-shaped body at a relative position, so that the structure is simpler, and the material is saved on the aspect of ensuring the sealing effect.
In order to ensure the sealing effect of the whole sealing ring 1, at least two groups of bosses 2 are arranged on the annular body 11. Preferably, at least two sets of bosss 2 set up along cyclic annular body 11 equidistant, make the joint more firm to reach better sealed effect.
It should be noted that the shape of the annular body 11 may be circular, rectangular or other special shapes according to the shape of the specific seal ring groove 100.
In this embodiment, still provide a sealing member, including three above-mentioned sealing washer 1, can be used for the sealed of the sealed annular groove 100 that the article font distributes among the automobile parts, three sealing washer 1 sets up along circumference interval, and connects through connecting portion 12 between two liang of sealing washers 1, and three sealing washer 1 is the article font through connecting portion 12 and sets up promptly for sealed the sealed annular groove 100 that the article font distributes among the automobile.
Specifically, each sealing ring 1 is provided with at least one set of boss 2 at one end far away from the connecting portion 12, and each set of boss 2 includes one boss 2 arranged inside the annular body 11 and one boss 2 arranged outside the annular body 11, so as to position the outside of the delta-shaped annular body 11 and ensure the sealing of the sealing ring groove 100 far away from the connecting portion 12.
Further specifically, in order to ensure the clamping effect at the connecting portions 12, a set of bosses 2 are arranged on one of the connecting portions 12, and the bosses 2 are arranged on the inner sides of at least two annular bodies 11 opposite to the connecting portions 12.
