Abstract
The utility model discloses a kind of closure seal ring, be made up of sealing circle body, be respectively equipped with at least twice convex tendon on the upper/lower terminal face of sealing circle body, on the inside and outside wall of sealing circle body, interval is evenly provided with boss, the utility model have upper and lower end face be two seals convex tendon, more reliable and stable when compressing, not easily topple over, not easily deviate from, the feature of easy installation and removal.
Description
Technical field
The utility model belongs to closure sealed product technical field, especially relates to a kind of closure seal ring.
Background technique
Engine air throttle body sealing ring generally designs the structure that the upper and lower two ends of employing are single track sealed muscle, reach good sealing effect and need enough surface pressures, end face is that the throttle body seal ring of single track sealed muscle can produce large area of contact, thus the pressure distribution on sealing surface can be made uneven; And existing seal ring is very easily deviate from from solar term gate slot, be not easy to installing/dismounting simultaneously and change.
Summary of the invention
The purpose of this utility model be to improve prior art deficiency and provide a kind of upper and lower end face be two seals convex tendon, more reliable and stable when compressing, not easily topple over, not easily deviate from, the closure seal ring of easy installation and removal.
The purpose of this utility model is achieved in that a kind of closure seal ring, is made up of sealing circle body, is characterized in being respectively equipped with at least twice convex tendon on the upper/lower terminal face of sealing circle body.
In order to realize the purpose of this utility model further, can be that interval is evenly provided with boss on the inside and outside wall of sealing circle body.
In order to realize the purpose of this utility model further, can be outwards have a projection on sealing circle body.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model adopts and be respectively equipped with at least twice convex tendon on the upper/lower terminal face of sealing circle body, the contact of seal ring and end face is two circle sealing surfaces, not only sealing surface upward pressure is evenly distributed, if wherein one sealing surface produces defect or when breaking, another road sealed muscle can also continue realize sealing, compress time more reliable and stable, not easily topple over; On the inside and outside wall of sealing circle body, interval is evenly provided with boss, is used for ensureing that seal ring position in groove is placed in the middle, seal ring can also be made to be fixed in solar term gate slot simultaneously, prevent from; Sealing circle body outwards has a projection, can easily take out in groove in order to seal ring and put into.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the sectional view of Fig. 1.
Fig. 3 is another kind of structural representation of the present utility model.
Embodiment
A kind of closure seal ring, with reference to Fig. 1, Fig. 2, is by the injection molding sealing circle body 1 of rubber injection machine, and on the upper/lower terminal face of sealing circle body 1, injection moulding simultaneously has at least twice convex tendon 2, and the present embodiment adopts twice.
On the inside and outside wall of sealing circle body 1, interval is evenly provided with multiple boss 3, with reference to Fig. 3, is used for ensureing that sealing circle body 1 position in groove is placed in the middle, sealing circle body 1 can also be made to be fixed in solar term gate slot simultaneously, prevent from.
Can easily take out in groove to seal circle body 1 and put into, sealing circle body 1 outwards has a projection 4.
This sealing circle body 1 main sealing zone is engine air throttle body, and what rubber-moulding adopted is injector injection moulding.
