Abstract
The utility model discloses a novel pneumatic sealing ring, which comprises a framework and a sealing ring, wherein three convex external rings are arranged on an external circumferential surface of the sealing ring; an upper groove is arranged between an upper external ring and a middle external ring; a lower groove is arranged between the middle external ring and a lower external ring. In the pneumatic sealing ring, the three convex external rings are arranged on the external circumferential surface of the sealing ring; during the use process, the three external rings are stressed and three sealing faces are formed; in this way, one sealing ring has the effect of three sealing rings; when one of the sealing faces is damaged, the two sealing faces still ensure the sealing effect, so the sealing effect is very good.
Description
Technical field:
The utility model relates to pneumatic auxiliary technical field, relates to a kind of novel pneumostop circle in particular.
Background technique:
The pneumostop circle, be important a kind of in the pneumatic auxiliary, it roughly is divided into two kinds of motive sealing and static seals, and required sealing is a static seal between similar cylinder cap and the cylinder barrel, the place that it is used for fixing, the sealing that is similar between piston rod and the cylinder barrel is called motive sealing, motive sealing is used in rotation, to-and-fro motion position, and the static seal ratio is easier to, and is less demanding, motive sealing is then because be reciprocal motion, friction, so very high requirement is arranged.
The existing pneumostop circle that is used for motive sealing, see accompanying drawing 1, constitute by skeleton A and seal ring B, on the outer peripheral surface of seal ring, be smooth, it is subjected to gas pressure when in use, be compressed the back and form a sealing surface, be used for sealing, and, generally all require to do very smoothly with its excircle surface of contact workpiece in order to obtain reasonable sealing effect, it is smooth more good more to can be described as, if rough meeting causes gas leakage, so will be very high for the requirement of workpiece, also just increased cost.But, facts have proved that though the pneumostop circle price of existing structure is not low, its sealing effect is really and is bad.
The model utility content:
The purpose of this utility model is at the deficiencies in the prior art part, and a kind of novel pneumatic seal ring is provided, and the outer shroud of three protrusions is arranged on its seal ring with outer side face, and technology is very simple when making, price is also inexpensive, and sealing effect is fine.
Technology solution of the present utility model is as follows:
The novel pneumatic seal ring comprises skeleton and seal ring, and the upper, middle and lower outer shroud of three protrusions is arranged on the described seal ring with outer side face, and described going up between outer shroud, the middle outer shroud has upper groove; Between outer shroud, the following outer shroud low groove is arranged in described.
Described novel pneumatic seal ring, described longitudinal cross-section of going up outer shroud, middle outer shroud, following outer shroud all is circular arc.
Described novel pneumatic seal ring, described upward outer shroud, middle outer shroud, following outer shroud are equidistantly arranged.
Described novel pneumatic seal ring, the bottom surface of described upper groove, low groove are two planes, and the outer peripheral surface of these two planes and described seal ring is on a circumferential surface.
Described novel pneumatic seal ring, described upward outer shroud, middle outer shroud, following outer shroud and described seal ring are one-body molded
The utility model beneficial effect is:
1) this novel pneumostop circle, it is by being provided with the outer shroud of three protrusions on the outer peripheral surface of seal ring, when in use, three outer shrouds can form three sealing surfaces when being squeezed, such seal ring just is equivalent to three seal rings and is using, under the situation of a sealing surface damage therein, also have two sealing surfaces guaranteeing sealing effect, so sealing effect is very good naturally.
2) Fig. 1 pneumostop circle external sealed face is to face directly, though highly close when extruding assembling the intermediate portion rubber body uphold nowhere, rubber body can be upheld when being provided with groove between these novel three outer shrouds of pneumostop circle and being squeezed, counterpart has tiny defect to remedy by rubber body, the requirement that cooperates workpiece is reduced greatly, and sealing effect is better.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the structural representation of existing pneumostop circle;
Fig. 2 is this novel structural representation;
Fig. 3 is this novel solid figure.
Embodiment:
The following stated is preferred embodiment of the present utility model only, is not that scope of the present utility model is limited.
Embodiment sees accompanying drawing 2,3; The novel pneumatic seal ring comprises skeleton 1 and seal ring 2, and the upper, middle and lower outer shroud 201,202,203 of three protrusions is arranged on described seal ring 2 outer peripheral surfaces, and described going up between outer shroud 201, the middle outer shroud 202 has upper groove 204; Between outer shroud 202, the following outer shroud 203 low groove 205 is arranged in described.
Described longitudinal cross-section of going up outer shroud 201, middle outer shroud 202, following outer shroud 203 all is circular arc.
Described upward outer shroud 201, middle outer shroud 202, following outer shroud 203 are equidistantly arranged.
The bottom surface of described upper groove 204, low groove 205 is two plane 204a, 205a, and the outer peripheral surface 206 of these two planes and described seal ring is on a circumferential surface.
Described upward outer shroud 201, middle outer shroud 202, following outer shroud 203 and described seal ring 2 are one-body molded.
