Abstract
This utility model is the dustproof construction of a kind of steel pipe size reducing machine hydraulic jack, dustproof construction is the key factor that can oil cylinder normally work, this dustproof construction includes two parts: interior dust cover and outer dust ring, interior dust cover is by a ring-type upper lip, there is individual annular transitional zone below upper lip, below annular transitional zone, have individual tapering transition band, below tapering transition band, have ring-type lower lip, outer dust ring has annulus upper holder, has annular ring below annulus upper holder.It solving prior art only to seal with sealing ring, easily by the problem of dust impurity effect sealing, it directly changes the path of impurity dust by it from cylinder body is discharged in other places.
Description
Technical field
This utility model relates to the dustproof construction of a kind of steel pipe size reducing machine hydraulic jack, is that one prevents dust from entering oil cylinder
Internal dust guard.
Background technology
Dirt-proof boot traditional in prior art all encloses etc. dust-proof by sealing shroud, lattice, and it is right that impurity is piled up in the trench
Extrude outside groove, it could even be possible to sealing ring, lattice are enclosed and extrude in groove, scratch inwall, affect sealing, miscellaneous
Matter also keeps certain moisture to increase the probability of exterior channels one corrosion, and impurity makes hydraulic oil retrogradation in penetrating into cylinder body simultaneously
Block valve body, cause oil cylinder frequently to unpick and wash normally to use oil cylinder seriously can be made to scrap.
Summary of the invention
This utility model discloses the dustproof construction of a kind of steel pipe size reducing machine hydraulic jack, in order to solve in prior art
Impurity dust enters inside oil cylinder, scratches inwall, the problem affecting sealing.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions.
The dustproof construction of a kind of steel pipe size reducing machine hydraulic jack, including interior dust cover 7 and 8 two portions of outer dust ring
Point, described interior dust cover top has a ring-type upper lip 1 to have an annular transitional zone 2 along its lower inside, has one below intermediate zone
Ring conical banda 3, has a ring-type lower lip 4 below ring conical banda, outer dust ring has annulus upper holder 5, is ring under annulus upper holder
6 are enclosed under shape.
The dustproof construction of a kind of steel pipe size reducing machine hydraulic jack as above, is arranged on oil cylinder inner wall by upper lip 1
In groove 9, conical surface set 10 within it blocks.
The dustproof construction of a kind of steel pipe size reducing machine hydraulic jack as above, is arranged on top on piston 11 by lower lip
In groove 12, outer dust cover 8 its top again compresses.
The dustproof construction of a kind of steel pipe size reducing machine hydraulic jack as above, interior dust cover 7 uses corrosion-and high-temp-resistant
High performance silica gel.
The dustproof construction of a kind of steel pipe size reducing machine hydraulic jack as above, being presented a theatrical performance as the last item on a programme by outer dust ring 8 annulus 5 is arranged on
Piston 11 top.
The dustproof construction of a kind of steel pipe size reducing machine hydraulic jack as above, outer dust ring 8 uses round steel to make.
The dustproof construction of a kind of steel pipe size reducing machine hydraulic jack as above, blocks dust drops in piston up-down
Time the gap that produce internal with oil cylinder in.
In sum owing to have employed technique scheme, solve impurity dust in prior art and enter inside oil cylinder, scrape
Flower inwall, affect the problem of sealing, it directly by impurity dust gear outside from other places discharge cylinder body, ensure that simultaneously
Internal sealing, substantially increases the service life of oil cylinder.
Accompanying drawing explanation
Dust cover sectional view in the dustproof construction of Fig. 1 present invention a kind of steel pipe size reducing machine hydraulic jack.
The outer dust ring sectional view of the dustproof construction of Fig. 2 present invention a kind of steel pipe size reducing machine hydraulic jack.

Detailed description of the invention
With embodiment, the present invention is described further below in conjunction with the accompanying drawings.
Fig. 1 is the dustproof construction of the present invention a kind of steel pipe size reducing machine hydraulic jack, refers to Fig. 1 one steel pipe size reducing machine liquid
Dust cover sectional view in the dustproof construction of compressing cylinder, including: a ring-type upper lip 1, annular transitional zone 2, ring conical banda 3,
Ring-type lower lip 4.
The ring-type upper lip 1 of the present invention shown in Fig. 1 is arranged on the top of interior dust cover 7, and the lower section of ring-type upper lip is
Annular transitional zone 2, the lower section of annular transitional zone is ring conical banda 3, is ring-type lower lip 4 below ring conical banda.
The outer dust ring sectional view of the dustproof construction of a kind of steel pipe size reducing machine hydraulic jack shown in Fig. 3, outer dust ring 8 is provided with
Annulus upper holder 5, is annular ring 6 under annulus upper holder.
Fig. 3 is the dustproof construction installation diagram of the present invention a kind of steel pipe size reducing machine hydraulic jack, the upper lip of interior dust cover in Fig. 3
Mouth is arranged in the groove 9 of oil cylinder inner wall, and taper sheath 10 is blocked.
In shown in Fig. 3, the ring-type lower lip 4 of dust cover is arranged in the groove 12 on piston 11 top, and outer dust ring 8 is by it
Compress.
In shown in Fig. 1, dust cover uses High performance silica gel to have higher mechanical strength and tearing strength, excellent vibration damping
Shock-absorbing capacity, high temperature resistant, oil resistant are wear-resisting, abrasion resistance is strong.
Outer dust cover shown in Fig. 3 is arranged on top land and compresses the ring-type lower lip that interior dust ring is transferred.
The length of outer dust cover annular ring shown in Fig. 2 is more than the distance of piston up-down.
Outer dust cover shown in Fig. 2 is made up of round steel.
Can produce certain gap with oil cylinder inner wall when piston moves up and down shown in Fig. 3, the ring-type upper lip of dust cover is installed
In oil cylinder inner wall groove, ring-type lower lip is arranged on top land, and dust is directly vacated from centre along dust cover when falling
Part falls, and main file dust falls in oil cylinder thoroughly.
