Abstract
The utility model relates to a dual-purpose seal ring of a shaft hole for the internal sealing of hydraulic cylinder and the external sealing of a projection shaft, particularly to a dual-purpose seal ring of a Y-shaped concave bottom shaft hole, which comprises a circular ring, and the cross section of the circular ring is Y-shaped. The dual-purpose seal ring is characterized in that the bottom part of the cross section is a groove, and an inner and an outer circular edgings are formed on the two edges of the groove. As the bottom part of the circular ring is a groove and the inner and the outer circular edgings are formed on the two edges of the groove, the shrinkage, the elasticity, the sealing performance and the universality of the bottom plane of the seal ring are all improved; and during the production, after the characters of model, trademark and specification are stored in the groove, the sealing performance of the seal ring is not influenced, and the appearance becomes more attractive.
Description
Technical field
The utility model is a kind of dual-purpose seal ring of axis hole that is used for interior sealing of oil hydraulic cylinder and projecting shaft external sealed.The dual-purpose seal ring of particularly a kind of Y type concave bottom axis hole.
Background technique
The dual-purpose seal ring of axis hole has two kinds of use, and the hole time spent is used for the sealing in the high-voltage oil cylinder, and the piston shaft that the axle time spent is used for being stretched out in the high-voltage oil cylinder seals.The dual-purpose seal ring of existing axis hole as shown in Figure 1, the sealing circle comprises an annular ring 1, the section configuration of annular ring 1 is the Y type, the cross section after described section refers to annular ring disconnected, the bottom of Y type is plane 2.The dual-purpose seal ring of existing axis hole, the both sides shrinkage is less inside and outside the seal ring when work, has increased the degree of wear of seal ring, has reduced the seal degree to high-voltage oil cylinder or piston shaft.Aborning, also the writing of model, trade mark and specification will be protruded on plane 2, this sealability to seal ring can only be harmful and none profit.
Summary of the invention
The purpose of this utility model is in order to overcome the defective of the existing dual-purpose ring wear degree of axis hole high sealing degree difference, to invent the dual-purpose seal ring of a kind of Y type concave bottom axis hole.
The purpose of this utility model realizes as follows: the dual-purpose seal ring of described Y type concave bottom axis hole, comprise an annular ring, the section of annular ring is the Y type, it is characterized in that: the bottom of section is a groove, and the both sides of groove constitute two inside and outside annular edge strips.
Good effect of the present utility model is as follows: because the bottom of annular ring is a circle groove, the both sides of groove constitute two inside and outside annular edge strips, so increased the shrink grading of seal ring bottom plane, make spring rate better, and sealability is higher, and versatility is stronger; Aborning, the font of model, trade mark and specification is deposited in the groove, the sealability that this does not influence seal ring at all also makes outward appearance more beautiful.
Description of drawings
Fig. 1 is the existing dual-purpose ring structure figure of axis hole;
Fig. 2 is the utility model structural drawing.
Among the figure: 1, annular ring; 2, plane;
3, groove; 4 annular edge strips.
Embodiment
As shown in Figure 2, the dual-purpose seal ring of described Y type concave bottom axis hole comprises an annular ring 1, and the section of annular ring 1 is the Y type, it is characterized in that: the bottom of section is a groove 3, and the both sides of groove 3 constitute two inside and outside annular edge strips 4.
Because the bottom of annular ring is a circle groove, the both sides of groove constitute two inside and outside annular edge strips, so increased the shrink grading of seal ring bottom plane, make spring rate better, and sealability is higher, and versatility is stronger; Aborning, the font of model, trade mark and specification is deposited in the groove, the sealability that this does not influence seal ring at all also makes outward appearance more beautiful.
