Abstract
The utility model discloses a sealing device aims at providing the sealing device that sealing performance is good, and its technical scheme main points are, changeing epaxial axle sleeve and setting up the seal receptacle on the pump body including setting up, the seal receptacle opening part be equipped with the ring channel, the ring channel in be equipped with at least a set of seal assembly, seal assembly include the seal lip that two at least parallel configuration and tip all contradicted with the axle sleeve, through setting up the ring channel in the seal receptacle, easy to assemble and fixed seal assembly, and multiunit seal assembly sets up ability greatly increased sealing performance side by side, seal assembly include the seal lip that two at least parallel configuration and tip all contradicted with the axle sleeve to seal lip greatly increased that row set up sealing performance, and seal lip is because impurity or medium when becoming invalid, good sealing performance still can be guaranteed to all the other seal lips, has guaranteed stable sealing performance promptly.
Description
Technical field
This utility model is related to a kind of sealing device.
Background technology
Oil sealing is used to the mechanically-sealing apparatus of oil sealing, it by need in drive disk assembly lubricate part with exert oneself part every
From being unlikely to allow oil seepage.Traditional oil sealing is all single lip seal, when sealing lip lost efficacy, leads to whole oil seal failure,
Safety coefficient is low.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of sealing device of good seal performance.
Technical solution of the present utility model is to provide a kind of sealing device with following structure, including being arranged on
Axle sleeve in rotating shaft and be arranged on seal receptacle on the pump housing, is provided with cannelure at described seal receptacle opening, described annular
It is provided with least one set black box, described black box includes at least two laid out in parallel and is all conflicted with axle sleeve in end in groove
Sealing lip.
Preferably, described black box includes fixed seat, is provided with the appearance for fixing seal lip in described fixed seat
Put groove.
Preferably, it is provided with some and sealing lip conflict in described storage tank to be evenly spaced in sealing lip in fixed seat
Stator.
Preferably, described seal receptacle is connected with closure, and described closure inwall and black box are conflicted with will be close
Sealing assembly is fixed.
Preferably, it is provided with, between described black box, the locating piece being slidably connected in cannelure.
Preferably, described annular groove sidewall is provided with groove, is provided with the sealing conflicted with black box in described groove
Circle.
Preferably, described fixed seat is L-shaped.
After above structure, sealing device of the present utility model, compared with prior art, there is advantages below：Pass through
Cannelure is set in seal receptacle, conveniently installs and fixing seal assembly, and multigroup black box is set up in parallel and can greatly increase
Sealing property, described black box includes the sealing lip all conflicted at least two laid out in parallel and end with axle sleeve, sets side by side
The sealing lip put considerably increases sealing property, and a sealing lip is because, when impurity or medium inefficacy, remaining seals
Lip still can guarantee that good sealing property, that is, ensure that stable sealing property.
Brief description
Fig. 1 is the cross section structure diagram of sealing device of the present utility model.
Shown in figure：1st, rotating shaft；2nd, axle sleeve；3rd, seal receptacle；4th, cannelure；5th, sealing lip；6th, fixed seat；7th, stator；
8th, closure.
Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Refer to shown in Fig. 1, sealing device of the present utility model, including the axle sleeve 2 being arranged in rotating shaft 1 and be arranged on
Seal receptacle 3 on the pump housing, is provided with cannelure 4, is provided with least one set close in described cannelure 4 at described seal receptacle 3 opening
Sealing assembly, described black box includes the sealing lip 5 all conflicted at least two laid out in parallel and end with axle sleeve 2, by
Setting cannelure 4 in seal receptacle 3, conveniently installs and fixing seal assembly, and multigroup black box is set up in parallel and can greatly increase
Sealing property, described black box includes the sealing lip 5 all conflicted at least two laid out in parallel and end with axle sleeve 2, side by side
The sealing lip 5 of setting considerably increases sealing property, and sealing lip 5 due to impurity or medium lost efficacy when, remaining
Sealing lip 5 still can guarantee that good sealing property, that is, ensure that stable sealing property.
Described black box includes fixed seat 6, and described fixed seat 6 is L-shaped, conveniently setting stator 7 and sealing
Lip 5, is provided with the storage tank for fixing seal lip 5 in described fixed seat 6, by fixed seat 6, multiple sealing lips 5 are fixing,
And black box unification is put into by cannelure 4 by fixed seat 6, convenient installation is fixed, and keeps in repair when being easy to be out of order, described
It is provided with storage tank and some conflict with the stator 7 being evenly spaced in sealing lip 5 in fixed seat 6, by fixation with sealing lip 5
Piece 7 realizes multiple 5 points of laid out in parallel of sealing lip, simple and reliable for structure, and is easy to sealing lip 5 and changes, described black box it
Between be provided with the locating piece being slidably connected in cannelure 4, can be equipped with seal receptacle 3 it is ensured that closure 8 with black box
Fixing seal assembly can be stablized, described seal receptacle 3 is connected with closure 8, described closure 8 inwall is conflicted with black box
To fix black box, will realize one-time fixing individual black box by closure 8, convenient and swift, black box leads to
Cross the change that black box number is realized in locating piece cooperation, adapt to multiple environment, and change conveniently.
Described cannelure 4 side wall is provided with groove, is provided with the sealing ring conflicted with black box, passes through in described groove
Sealing ring ensures the cooperation between black box and seal receptacle 3, and black box is passed through further with the resilient engagement of sealing ring
Sealing property between reinforced sealed assembly and axle.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonging under this utility model thinking belong to protection domain of the present utility model.Should refer to
Go out, for those skilled in the art, some improvement under the premise of without departing from this utility model principle and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
