Description
Technical field
The utility model relates to technical field of sealing technology, particularly relates to sealing gasket.
Background technique
Sealing gasket comprises the sealant layer of matrix and matrix side, and matrix has screw; In prior art, the sealer at screw place is the same with the sealant layer thickness at other positions, and does not arrange seal ring at screw place, and such sealing gasket in use often from screw seepage, has the shortcoming of sealing effect difference.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, provides the sealing gasket of a kind of screw place good sealing effect---sealing screw sealing gasket.
The technical solution of the utility model is achieved in that sealing screw sealing gasket, comprise the sealant layer of matrix and matrix side, matrix there is screw, it is characterized in that: described side, screw place is also bonded with silica gel ring, and the diameter of bore of described silica gel ring is less than the external diameter will installing screw.
Say further, the bevelled extension of described silica gel ring periphery tool, extension is bonded on matrix, and the length of extension is 5-8 millimeters.
Say further, there is above-mentioned silica gel ring upper and lower two sides at described screw place.
The beneficial effects of the utility model are: such sealing gasket has the tight advantage of sealing, has particularly stopped the disadvantage of screw place seepage; Described silica gel ring periphery has extension, and the length of extension is 5-8 millimeters, has the advantage preventing silica gel ring from coming off; There is above-mentioned silica gel ring upper and lower two sides at described screw place, have the better advantage of sealing effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cross-sectional view at screw place.
Wherein, 1, matrix 2, sealant layer 3, screw 4, silica gel ring 5, extension.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, sealing screw sealing gasket, comprises the sealant layer 2 of matrix 1 and matrix side, matrix has screw 3, it is characterized in that: described side, screw place is also bonded with silica gel ring 4, and the diameter of bore of described silica gel ring is less than the external diameter will installing screw.Like this, after screw passes, could interference fit be formed, there is advantage of the present utility model.
Say further, the bevelled extension 5 of described silica gel ring periphery tool, extension is bonded on matrix, and the length of extension is 5-8 millimeters, and such silica gel ring and matrix combine closely, prevent coming off of silica gel ring.
Say further, there is above-mentioned silica gel ring upper and lower two sides at described screw place.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed in the scope of the claims of the present utility model.
