Abstract
The present invention is a kind of vacuum adsorption type rubber seal, including cricoid sealing ring ontology, which is characterized in that the sealing ring ontology includes upper ring surface, lower anchor ring, and the upper ring surface, lower anchor ring are equipped with the groove of annular.The depth of the groove is the 1/4~1/3 of the thickness of the sealing ring ontology.The equal rounded corner of corner angle of the sealing ring ontology.Beneficial effects of the present invention are as follows：New technical solution enables sealing performance more perfect, and appointing under the influence of age hardening by sealing ring can so keep good sealing performance to have effect outstanding.
Description
Technical field
The present invention relates to rubber products, and in particular to a kind of vacuum adsorption type rubber seal.
Background technology
Existing rubber seal has the following disadvantages, and sealing ring is easy to happen aging after being used for a long time, close after aging
Seal hardness increases and elasticity weakens.In addition the deformation of sealing ring also causes sealing ring locally to generate gas chamber, leads to sealing performance
Decline or even failure, it is therefore desirable to provide a kind of stronger sealing ring of sealing performance to solve above-mentioned technical problem.
Invention content
The present invention provides a kind of vacuum adsorption type rubber seal, design and develop the purpose of the present apparatus, it is proposed that a kind of
New technical solution enables sealing performance more perfect, and appointing under the influence of age hardening by sealing ring can so keep
Good sealing performance has effect outstanding.
Present invention employs following technical solutions：A kind of vacuum adsorption type rubber seal, including cricoid sealing ring sheet
Body 1, which is characterized in that the sealing ring ontology 1 includes upper ring surface 2, lower anchor ring 3, and the upper ring surface 2, lower anchor ring 3 are equipped with ring
The groove 4 of shape.
The depth of the groove 4 is the 1/4~1/3 of the thickness of the sealing ring ontology 1.
The equal rounded corner of corner angle of the sealing ring ontology 1.
Beneficial effects of the present invention are as follows：During this sealing ring carries out use, the upper ring surface 2, lower anchor ring 3 are made
It is squeezed by external force for compressive plane, to which 4 crimp of the groove causes the gas of trench interiors to be released, due to rubber
The effect of screen resilience, it is in form trend to force groove so that vacuum state is presented in groove, since the effect of atmospheric pressure makes this
Sealing ring ontology 1 tightly adsorbs and sealing station, fitted closely with workpiece, achieve the purpose that it is sufficiently sealed.New technical solution
Enable sealing performance more perfect, good sealing performance can so be kept by appointing under the influence of age hardening by sealing ring
With effect outstanding.
Description of the drawings
Fig. 1 is the schematic diagram of the vacuum adsorption type rubber seal of the present invention.
Fig. 2 is the schematic cross-section of the vacuum adsorption type rubber seal in Fig. 1.
Specific implementation mode
Below in conjunction with attached drawing, the invention will be further described with specific embodiment.
In Fig. 1,2：Sealing ring ontology 1, upper ring surface 2, lower anchor ring 3, groove 4.
A kind of vacuum adsorption type rubber seal, including cricoid sealing ring ontology 1, the sealing ring ontology 1 include upper
Anchor ring 2, lower anchor ring 3, the upper ring surface 2, lower anchor ring 3 are equipped with the groove 4 of annular.
The depth of the groove 4 is the 1/4~1/3 of the thickness of the sealing ring ontology 1.
The equal rounded corner of corner angle of the sealing ring ontology 1.
During this sealing ring carries out use, the upper ring surface 2, lower anchor ring 3 are squeezed as compressive plane by external force,
To which 4 crimp of the groove causes the gas of trench interiors to be released, due to the effect of the screen resilience of rubber, groove is forced
In forming trend so that vacuum state is presented in groove, due to the effect of atmospheric pressure make this sealing ring ontology 1 tightly adsorb and
Sealing station, fitted closely with workpiece, achieve the purpose that it is sufficiently sealed.
