Abstract
The utility model relates to a sealing ring for pressure cooker. The outside of the sealing ring is provided with a horizontal press-in surface(1), which heaves outwards and the inner side of which is provided with a trumpet type opening(2) which expands upwardly and downwardly. The utility model is characterized in that the inside of the press-in surface(1) is provided with a compressing cavity(3) which extends from the trumpet type opening(2) towards the press-in surface(1). The utility model can increase the elastic compressed amount of the sealing ring press-in surface which is arranged between the pressure cooker cover and the cooker body, thus reducing the rotary friction between the pressure cooker cover and the cooker body and making the pressure cooker cover easier to be opened and closed through revolving; besides, the deepened trumpet type opening can fully expand under the pressure in the cooker so as to increase the leak tightness between the pressure cooker cover and the cooker body.
Description
Technical field
The utility model belongs to a kind of sealing ring of pressure cooker.
Background technology
Usually the seal ring of pressure cooker outside be level to stitching surface (1), stitching surface is inboard to open the horn mouth (2) of shape for triangle linearly, during use horizontal stitching surface is clipped between pressure cooker cover and the pot body, the rotation pot cover fastens pot cover pot body, because the stitching surface of existing seal ring of pressure cooker is solid, so the elastic compression surplus is little, frictional force when having strengthened the rotation pot cover, make pressure cooker cover be difficult for the rotation folding, if strengthen the fit clearance of pot cover and pot body, can reduce the sealing of pressure cooker again.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of can reduce pressure cooker cover and the pot body between spin friction power, make pressure cooker cover be easier to rotate folding, can improve the seal ring of pressure cooker of sealing again.
The technical scheme that addresses the above problem is (referring to implementing illustration): the utility model seal ring of pressure cooker outside be provided with the level that outwards bloats to stitching surface (1), the stitching surface inboard is provided with open horn mouth (2) up and down, it is characterized in that: be provided with the compaction cavum (3) that extends from open horn mouth (2) in the described stitching surface (1) in stitching surface.
Owing to be provided with the compaction cavum (3) of hollow in the stitching surface of the present utility model, so can increase be clipped in pressure cooker cover and and the elastic compression amount of the sealing ring stitching surface of pot between the body, thereby reduce the spin friction power between pressure cooker cover and the pot body, make pressure cooker cover be easier to rotate folding, and when forming pressure in the pot, gases at high pressure in the compaction cavum can outwards apply expansionary force in stitching surface, horn mouth is fully opened, and improve the sealing between pressure cooker cover and the pot body.

Specific embodiments
The present embodiment sealing ring outside for the level that outwards bloats to stitching surface 1, the horn mouth that the inboard set horn mouth 2 of stitching surface inwardly magnifies for the camber bending, be provided with the compression chamber 3 that in stitching surface, extends from horn mouth in the stitching surface, the wall thickness of 3 li portion's vertical positions of compression chamber is greater than the wall thickness at lower wall on the compression chamber and arc horn mouth place, to improve the intensity and the fracture resistence force of sealing ring.
The horn mouth that arc magnifies is easier to fully open the sealing that improves pot cover pot body.
Claims (3)
1, seal ring of pressure cooker, the sealing ring outside be provided with the level that outwards bloats to stitching surface (1), the stitching surface inboard is provided with open horn mouth (2) up and down, it is characterized in that: be provided with the compaction cavum (3) that extends from open horn mouth (2) in the described stitching surface (1) in stitching surface.
2, seal ring of pressure cooker according to claim 1 is characterized in that: the horn mouth that the inboard set horn mouth (2) of described stitching surface inwardly magnifies for the camber bending.
3, seal ring of pressure cooker according to claim 2 is characterized in that: the wall thickness of described compression chamber (3) lining portion vertical position is greater than the wall thickness at lower wall on the compression chamber and arc horn mouth place.
