Abstract
The utility model discloses a dovetail groove capable of positioning an O-shaped ring through the conical surface. A dovetail groove (4) is arranged on the contact sealing surface of a connecting piece (1) and a base body (3); an O-shaped rubber ring (2) is installed in the dovetail groove (4); the angle of the dovetail is 24 degrees; and the opening and the depth of the groove are 0.5-0.8mm smaller than the diameter of the section of the O-shaped rubber ring (2). The utility model adopts the dovetail groove to position the O-shaped rubber ring and the O-shaped rubber ring can be accurately positioned through the conical surface of the dovetail groove and is fixed firmly, not easy to fall off, simple to assemble and reliable in sealing.
Description
Technical field
The utility model relates to seal form, is specifically related to the sectional shape of O shape circle groove and the location of sealing surface.
Background technique
At present, it is end face seal, piston or rod seal that the machinery industry generally adopts the form of O type circle sealing, its groove form is U-shaped, but at the big heavier component of assembling, especially adopt end face seal, when groove opening was downward, O type circle very easily moved and comes off, bring great difficulty to assembling work, influence the sealing effect of product.
Summary of the invention
The purpose of this utility model is: the dovetail groove of a kind of conical surface location O type circle is provided, this dovetail groove overcome groove opening when downward O type circle easily move defectives such as coming off, assemble difficulty, and sealing surface accurate positioning, assembling is simple, sealing is reliably.
Technical solution of the present utility model is: establish dovetail groove at the sealing surface that link contacts with matrix, O shape rubber ring is installed in the dovetail groove, the dovetail angle is 24 °, and the degree of depth of opening and groove is less than O type rubber ring diameter of section 0.5～0.8mm.
In the dovetail groove of the conical surface of the present utility model location O shape circle, the opening abate of dovetail groove is in order to avoid scratch O type circle.
In the dovetail groove of the conical surface of the present utility model location O shape circle, the contact seal face of link and matrix is 23 ° of conical surfaces.
The utility model adopts dovetail groove location O shape rubber ring, and conical surface accurate positioning is fixed, difficult drop-off, and assembling is simple, and sealing is reliable.
Description of drawings
Fig. 1 is the utility model assembly structure figure.
Fig. 2 is the dovetail groove schematic representation of Fig. 1.
Among the figure: 1 link, 2O shape rubber ring, 3 matrixes, 4 dovetail grooves
Embodiment
As shown in Figure 1, establish dovetail groove 4 at the sealing surface that link 1 contacts with matrix 3, O shape rubber ring 2 is installed in the dovetail groove 4, the dovetail angle is 24 °, and the degree of depth of opening and groove is less than O type rubber ring 2 diameter of sections 0.5～0.8mm.
In the dovetail groove of the conical surface of the present utility model location O shape circle, the opening abate of dovetail groove 4 is in order to avoid scratch O type circle.
In the dovetail groove of the conical surface of the present utility model location O shape circle, link 1 is 23 ° of conical surfaces with the contact seal face of matrix 3.
Process annular dovetail slot on 23 ° of conical surfaces of link, utilize the resiliently deformable of rubber, O shape rubber ring is inserted in the dovetail groove, Open Side Down even make seal groove, and O shape rubber ring also is difficult for moving coming off; 23 ° of conical surfaces by link and matrix sealing surface carry out accurate guide-localization, by hold down gag link and matrix are compressed, and make it to carry out reliable sealing.
Claims (4)
1. the dovetail groove of conical surface location O shape circle is characterized in that: establish dovetail groove (4) on link (1) and matrix (3) contact seal face, O shape rubber ring (2) is installed in the dovetail groove (4).
2. the dovetail groove of the conical surface according to claim 1 location O shape circle, it is characterized in that: dovetail groove (4) angle is 24 °, the degree of depth of opening and groove is less than O type rubber ring (2) diameter of section 0.5～0.8mm.
3. the dovetail groove of the conical surface according to claim 1 location O shape circle is characterized in that: the opening abate of dovetail groove (4).
4. the dovetail groove of the conical surface according to claim 1 location O shape circle, it is characterized in that: link (1) is 23 ° of conical surfaces with the contact seal face of matrix (3).
