Abstract
The invention discloses an expansion type sealing ring, which comprises a sealing ring body, external threads, sealing lines, internal threads and a through hole, wherein the external threads are formed on the outer side of the sealing ring body; the sealing lines are formed at the two ends of the external threads; the sealing ring body is coaxially provided with the through hole in which the internal threads are formed. The expansion type sealing ring has the advantages of high reliability, compact structure, convenience in use and manufacturing, high sealing performance, high adaptability, long service life, high elasticity, low cost and the like, and meanwhile, has broad market prospect in the rubber sealing ring market.
Description
Technical field
The present invention relates to seal ring field, particularly relate to a kind of inflatable seal circle.
Background technique
Seal ring is a kind of part the most frequently used in Air-liquid pipeline, for ensureing the tightness between pipe joint, avoid pipe leakage, existing seal ring is generally rubber or metal manufacture, the selection of sealing ring material and structural form to its sealability and working life important in inhibiting, existing seal ring is generally small-sized packing ring, and the life-span is shorter and only can seal waiting thick pipeline enclosure.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of inflatable seal circle, realize the locking of knife rest by pneumatic mode and unclamp, the accurate tool changing of knife rest is realized by actuating motor and synchronous pulley, have that unfailing performance is high, registration, compact structure, transposition speed is fast, noise is little, the advantage such as cheap, simultaneously miniature numerical control lathe application and universal on have market prospects widely.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of inflatable seal circle, comprise: seal ring body, outside thread, sealing line, internal thread and through hole, described seal ring body arranged outside has outside thread, described outside thread two ends are provided with sealing line, seal ring body is coaxially arranged through hole, is furnished with internal thread in described through hole.
In a preferred embodiment of the present invention, described through hole is front end is taper, and rear end is cylindrical.
In a preferred embodiment of the present invention, described sealing line is annular groove, and described sealing line is provided with many, becomes equidistant placement between sealing line.
In a preferred embodiment of the present invention, described internal thread is arranged in cylindrical hole and conical through-hole place.
In a preferred embodiment of the present invention, described seal ring body is provided with stiffener rings in cylindrical hole part.
The invention has the beneficial effects as follows: inflatable seal circle of the present invention arranges taper by front end and arranges screw thread in inner side, ensure the expansibility of seal ring, improve sealing effect, by seal ring arranged outside screw thread and seal groove, ensure the multiple mounting modes of seal ring and mode seal ring leaks; Have that reliability is high, compact structure, easy to use, good airproof performance, strong adaptability, life-span length, good springiness, easily manufactured, the advantage such as cheap, 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 used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of inflatable seal circle one of the present invention preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, seal ring body, and 2, outside thread, 3, sealing line, 4, internal thread, 5, through hole.
Embodiment
Be clearly and completely described to the technological scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained 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 inflatable seal circle, comprise: seal ring body 1, outside thread 2, sealing line 3, internal thread 4 and through hole 5, described seal ring body 1 arranged outside has outside thread 2, described outside thread 2 two ends are provided with sealing line 3, seal ring body 1 is coaxially arranged through hole 5, is furnished with internal thread 4 in described through hole 5.
The through hole 5 of inflatable seal circle is made up of taper and cylindrical two-part, seal ring front end is taper, rear end is cylindrical, sealing line 3 is provided with inside cylindrical hole 5, be provided with screw thread at cylindrical and cone-shaped section inside through hole 5, ensure that the connection of seal ring and pipeline ensures the sealing effect of seal ring simultaneously.
The arranged outside of inflatable seal circle has annular groove shape to seal line 3, and sealing line 3 is provided with many and becomes equidistant placement, ensures the formation sealing that seal ring can be good.
Seal the multiple stiffener rings having metal ring to make in described seal ring body, improve seal ring intensity.
The beneficial effect of inflatable seal circle of the present invention is:
One, taper be set by front end and screw thread is set in inner side, ensureing the expansibility of seal ring, improving sealing effect;
Two, by seal ring arranged outside screw thread and seal groove, the multiple mounting modes of seal ring is ensured and mode seal ring leaks;
Three, have that reliability is high, compact structure, easy to use, good airproof performance, strong adaptability, life-span length, good springiness, easily manufactured, the advantage such as cheap, has market prospects widely in rubber seal market simultaneously.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; 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.
