It can be the connection inside two elements.For the ordinary skill in the art, on being understood by concrete condition
State concrete meaning of the term in the invention.
Below with reference to embodiment come the present invention will be described in detail create.
A kind of transition connection sealing element connects including the inside U-shaped seal 10 of opening and with it as shown in Figures 1 to 4
The U-shaped seal of the outward opening connect；U-shaped seal includes the interconnecting piece of buffer part and elastic buffer portion two sides；Two is U-shaped
Seal chamber 11 is formed between seal；The U-shaped seal includes the buffer part 12 of arc, is equipped with interconnecting piece at buffer part both ends
13；The interconnecting piece is in corrugated plate shape structure.
It should be noted that above-mentioned seal chamber vacuumize process, forms vacuum cavity, it can be in two U-shaped seals
Between form splendid sealing effect, guarantee the sealing performance of sealing element of the present invention.
The connection surface is equipped with guard ring 3, which includes contour two seals lip 4, the shape between two sealing lips
At dashpot 5；Several connecting holes 6 are offered in buffering trench bottom.
Wherein, each connecting hole is uniformly arranged centered on sealing axis, is connected side by the connectors such as screw 9
Portion is fixed on driving device (shell), so that its double sealing lip is compressed driving end, it is ensured that the leakproofness of the side；And it will be another
The interconnecting piece of side is fixed in the mounting base of mangler shaft, is formed the double sealing lip of the side and mounting base end face and is sealed, sealing
Property is very good.
It should be noted that gasket can be arranged in the connectors such as screw and buffering trench bottom, to guarantee reliable sealing
Property, the convenience of installation fixed operation is not only realized, but also will not have any impact to leakproofness.In fact, the nut portions of screw
The inner wall for the sealing that branch closely compresses itself is achieved that leakproofness, and therefore, the leakproofness of screw connection is can to obtain
Arrive reliable guarantee.
The above-mentioned U-shaped structure in elastic buffer portion, opening is towards outside, when the offset of sealing structure on two sides part appearance position
When, elastic buffer portion, which can take advantage of a situation, generates a certain amount of deformation, with compensate structure on two sides part torsion, shake situations such as caused by shifting
Position, still ensures that the reliable of connection, leakproofness is not affected.It therefore, will not even if there is the vibration of reamer or shaking
Integrally-built stability is influenced, this sealing has servo-actuated performance, and leakproofness is splendid.
The connecting hole interlaced arrangement of above-mentioned elastic buffer portion two sides passes through screw from U-shaped elastic buffer portion opening inner side
Equal connectors pass through connecting hole and are connected and fixed with external corresponding structural member (reamer axle bed 7 or driving device shell 8).This hair
The bright sealing fixed form provided of creating is simple, the structure without structural member and driving device end to original reamer part
Part is transformed, and can easily be installed, small to structure destruction, is mounted and dismounted high-efficient.Also, this sealing can also be with
As temporary sealing, it can quickly be mounted on the position for needing to seal.
This sealing can also be used as temporary sealing, can quickly be mounted on the position for needing to seal.In U-shaped seal
It connects and is provided with guard ring at hole.When by connectors such as bolts by being originally seal-installed on structural member, during tightening bolt, shield
Circle can realize with structural member surface and seal that bolt is pressed tighter, and leakproofness is better, phase more poorly sealed than traditional junction
Than leakproofness is increased dramatically.
It should be pointed out that the driving end fixed structure and reamer end fixed structure in the attached drawing of the invention can be with
Be interpreted as the model abstract to one of corresponding construction in existing equipment (because specific equipment at this structure may have it is certain poor
Not, not necessarily completely consistent with attached drawing).Purpose is intended to the clear and complete offer side of the technical solution description to the invention
It helps, understands convenient for technical staff.In fact, if a corresponding side structure provides corresponding groove (mounting groove of sealing),
Which kind of which kind of do not had using contour structures to the implementation of the invention as specific driving end using contour structures, reamer one end
There is materially affect, the application is not necessarily to make its structure specific limit.
Above-mentioned elastic buffer portion and interconnecting piece outer wall surface are coated with corrosion-resistant finishes.Above-mentioned elastic buffer portion and company
Socket part inner wall surface is coated with resistance to oil coating.Its outer surface has excellent Corrosion Protection, and inner surface oil resistivity is good, usability
Can be reliable and stable, the service life is long, and use cost is low.Corrosion-resistant finishes generally uses epoxy resin composite material coating or phenolic aldehyde ceramics
Coating is filled, is highly suitable for corroding water environment, can effectively resist corrosion, it is not easily to fall off, sealing element has been effectively ensured
Resistance to corrosion.
In an optional example, skeleton can be set on the inside of elastic buffer portion, specifically, skeleton can be with
It is metallic framework, is also possible to press from both sides the enhancement layer that fabric is constituted, can effectively improve the intensity in elastic buffer portion, resilience
It is good, after stress deformation, can Fast Restoration, be not likely to produce permanent deformation, ensured to greatest extent sealing reliability,
And its effect is connected and fixed to structural member.
It should be pointed out that the dashpot in the invention between two sealing lips is not only to play and connecting hole pair
It answers, convenient for wearing connector, realizes the connection of sealing and the effect of fixation, in fact, the dashpot is also the deformation of sealing lip
Provide sufficient space.Because reamer part is at work, it is easy to happen vibration, even if in normal operation, reamer
Head also has certain twisting, at this point, the sealing that the invention provides can not only be made up by the deformation in elastic buffer portion,
Meanwhile the sealing lip of guard ring also has the variation of stress accordingly, due to being double sealing lip, plays the sealing function of twin-stage,
It is higher than single track sealing reliability, even if the loaded deformation of two seals lip is different, leakproofness is not at all also influenced, because close
Envelope lip two sides provide sufficient space for sealing lipping, and sealing lipping is unrestricted, and leakproofness is splendid.
Above-mentioned elastic buffer portion is an integral molding structure with interconnecting piece.Above-mentioned guard ring is an integral molding structure with interconnecting piece.
Structural stability is good, and intensity is high.
The invention is equipped with guard ring in sealing and the junction of structural member, can effectively guarantee to connect installation place sealing
Reliability is padded, fixed form is simple, and the structural member without structural member and driving device end to original reamer part carries out
Transformation, can easily be installed, small to structure destruction, be mounted and dismounted high-efficient.It should be pointed out that cross of the invention
Section is equivalent to the structure of back-to-back type, strengthens the structural strength of sealing element, though not inside sealing element add fabric or
Skeleton, bending part are also hardly damaged, and manufacturing process is simple, at low cost.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
Protection scope within.
