Abstract
The invention discloses an extensible hollow sealing ring which comprises a support, a rubber ring, a hollow loop, an extension protrusion and an extension groove. The support is arranged in the rubber ring, the hollow loop is arranged in the center of the rubber ring, the extension protrusion is arranged on the rubber ring, and the extension groove is further formed in the rubber ring. According to the mode, the extensible hollow sealing ring has the advantages of being high in reliability, compact in structure, good in sealing performance, extensible in height and depth of the sealing ring, good in sealing performance when used for sealing an annular pipeline, low in price, high in adaptation and wide in market prospect in the rubber sealing ring market.
Description
Technical field
The present invention relates to rubber product field, particularly relate to a kind of hollow seal ring of expanding.
Background technique
O-ring seals is the most a kind of seal ring of long use in daily life, is mainly used in static seal and reciprocating movement sealing.While being used for rotatablely moving sealing, only limit to low speed rotary seal.Existing seal ring general size is fixed, wider for some sealed widths, the product that thickness is larger, and traditional O-ring seals seems inapplicable.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of hollow seal ring of expanding, and by support and hollow rubber are set, reduces material weight, has improved sealability, and has had good shape retention energy; Use projection and groove by design, further improved the sealability of seal ring; Be provided with trapezoidal projection and dovetail groove, make seal ring there is better combination seal ability; Have that reliability is high, compact structure, good airproof performance, seal ring height thickness can expand, and for advantages such as looped pipeline good leak tightness, cheap, strong adaptabilities, has market prospects widely in rubber seal market simultaneously.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of hollow seal ring of expanding is provided, comprise: ring support, rubber ring, hollow annular distance, expansion projection and expansion groove, in described rubber ring, be provided with ring support, rubber ring central position is provided with hollow annular distance, described expansion projection is arranged on rubber ring, and rubber ring is also furnished with expansion groove.
In a preferred embodiment of the present invention, described expansion convex cross section is trapezoidal, and expansion projection is arranged on upper end and the outside of rubber ring circular cross-section.
In a preferred embodiment of the present invention, described expansion groove is dovetail shaped, and expansion groove is arranged on lower end and the inner side of rubber ring circular cross-section.
In a preferred embodiment of the present invention, described ring support is arranged around hollow annular distance.
In a preferred embodiment of the present invention, the described hollow seal ring of expanding is provided with multiplely, and the excircle that inner side is hollow expands seal ring and outside be hollow, and to expand the inner circumference diameter of seal ring identical.
The invention has the beneficial effects as follows: the hollow seal ring of expanding of the present invention, by support and hollow rubber are set, reduces material weight, has improved sealability, and has good shape retention energy; Use projection and groove by design, further improved the sealability of seal ring; Be provided with trapezoidal projection and dovetail groove, make seal ring there is better combination seal ability; Have that reliability is high, compact structure, good airproof performance, seal ring height thickness can expand, and for advantages such as looped pipeline good leak tightness, cheap, strong adaptabilities, has market prospects widely in rubber seal market simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the hollow structural representation of expanding seal ring one preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, ring support, 2, rubber ring, 3, hollow annular distance, 4, expansion projection, 5, expansion groove.
Embodiment
To the technological scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skills, not making all other embodiments that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of hollow seal ring of expanding, comprise: ring support 1, rubber ring 2, hollow annular distance 3, expansion projection 4 and expansion groove 5, in described rubber ring 2, be provided with ring support 1, rubber ring 2 central positions are provided with hollow annular distance 3, described expansion projection 4 is arranged on rubber ring 2, and rubber ring 2 is also furnished with expansion groove 4.
Sealing circle Longitudinal Extension process is as follows, choose the seal ring of two equal sizes, the swallow-tail form expansion groove 5 that the inverted trapezoidal expansion projection 4 of lower seal upper end is aimed at upper seal ring lower end, depresses seal ring, expansion projection 4 is entered in expansion groove 5, complete the connection of seal ring.
Sealing circle process extending transversely is as follows, choose the seal ring of two different sizes, the swallow-tail form expansion groove 5 that the inverted trapezoidal expansion projection 4 in small sealing ring outside is aimed at big sealing ring inner side, compresses seal ring, expansion projection 4 is entered in expansion groove 5, complete the connection of seal ring.
The hollow beneficial effect of expanding seal ring of the present invention is:
One, by support and hollow rubber are set, reduce material weight, improved sealability, and there is good shape retention energy;
Two, use projection and groove by design, further improved the sealability of seal ring;
Three, be provided with trapezoidal projection and dovetail groove, make seal ring there is better combination seal ability;
Four, have that reliability is high, compact structure, good airproof performance, seal ring height thickness can expand, and for advantages such as looped pipeline good leak tightness, cheap, strong adaptabilities, has market prospects widely in rubber seal market simultaneously.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
