Description
Technical field
The utility model belongs to hydraulic circuit sealing element field, and in particular to hydraulic jack seal structural part.
Background technique
Hydraulic jack is that the functions such as support, traction are realized using hydraulic circuit, in use the property of hydraulic circuit
It can will directly affect the service performance of hydraulic jack.
In sealed hydraulic jack oil circuit, since single layer sealing ring is easy oil leak in use.Main cause exists
Reversion is easy to produce when the O-ring of sealing ring is in assembly；Lead to O-ring seal failure, generates oil leak.In the prior art in order to
The sealing performance for improving top cap mainly uses double-layer seal, there is the double-sealing device using oil cylinder, uses double sealing can be with
The problem of alleviating oil leak, but process, assemble relative complex, cost is also relatively higher.
Utility model content
The utility model provides hydraulic jack seal structural part, can effectively realize the sealing to hydraulic jack, and
It can be permanently effective.
In order to achieve the above technical purposes, the technical solution that the application takes is hydraulic jack seal structural part, including
The top cap of pedestal, the housing being mounted on the base and hermetically sealed case；Top cap includes the end cap and sleeve of integral type；Sleeve is set
In an end face of end cap, the anchor ring of sleeve is equipped with an annular groove；Seal structural part is equipped in annular groove；Seal structural part includes
Section is in the sealing ring of the recess portion formed between two neighboring protrusion and two protrusions；Sealing ring is realized to sleeve and outer inner room
Sealing.
As the improved technical solution of the application, protrusion is semicircular structure.
As the improved technical solution of the application, the size of recess portion is not more than 0.5mm.
As the improved technical solution of the application, the cell wall outer diameter that annular groove is bordered by end cover side is greater than the slot away from end cover side
The outer diameter of wall.
Beneficial effect
The application there are two protrusion, is equivalent to form double-layer seal, be stayed between double-layer seal using the section tool of sealing ring
There is recess portion, the sealing ring of double-layer seal avoids oil leak caused by generating reversion when installation top cap and cutting badly, and processes, assembly
Fairly simple, cost is also relatively low.And in summer high temperature environment lower seal expanded by heating, recess portion can overcome the disadvantages that two protrusions
The volume of expanded by heating avoids because of oil leak caused by sealing ring expansion.
To sum up, the technical solution of the application can facilitate the installation of top cap, avoid cutting bad generation oil leak because of section；It can mention again
High sealing effect；It can change the Inversion Problem generated when O-ring assembly simultaneously.
It should be appreciated that as long as aforementioned concepts and all combinations additionally conceived described in greater detail below are at this
It can be viewed as a part of the utility model theme of the disclosure in the case that the design of sample is not conflicting.
The foregoing and other side of the utility model introduction can be more fully appreciated from the following description in conjunction with attached drawing
Face, embodiment and feature.The features and/or benefits of other additional aspects such as illustrative embodiments of the utility model
To be obvious in the following description, or will be learnt in the practice by the specific embodiment instructed according to the utility model.
Detailed description of the invention
Attached drawing is not intended to drawn to scale.In the accompanying drawings, identical or nearly identical group each of is shown in each figure
It can be indicated by the same numeral at part.For clarity, in each figure, not each component part is labeled.
Now, by by example and be described in reference to the drawings the utility model various aspects embodiment, in which:
The decomposition texture schematic diagram of Fig. 1 the application hydraulic jack seal structural part；
The structural schematic diagram of Fig. 2 the application top cap installation；
The structural schematic diagram of Fig. 3 the application sealing ring；
In figure: 1, pedestal；2, housing；3, end cap；4, sealing ring；41, the first protrusion；42, the second protrusion；43, recess portion；5,
Annular groove deviates from end cover side cell wall；6, annular groove.
Specific embodiment
In order to know more about the technology contents of the utility model, spy lifts specific embodiment and institute's accompanying drawings is cooperated to be described as follows.
It is described with reference to the various aspects of the utility model in the disclosure, shown in the drawings of the implementation of many explanations
Example.It is not intended to cover all aspects of the utility model for embodiment of the disclosure.It should be appreciated that a variety of structures presented hereinbefore
Think and embodiment, and those of describe in more detail below design and embodiment can in many ways in any one
Implement, this is because conception and embodiment disclosed in the utility model are not limited to any embodiment.In addition, this is practical
Novel disclosed some aspects can be used alone, or with it is disclosed by the utility model it is otherwise it is any it is appropriately combined come
It uses.
As shown in Figure 1, hydraulic jack seal structural part, including pedestal 1, the housing being installed on pedestal 12, Yi Jimi
Seal the top cap of housing；Top cap includes the end cap 3 and sleeve of integral type；Sleeve is set to the one side of end cap 3, and the anchor ring of sleeve is equipped with
One annular groove 6；Seal structural part is equipped in annular groove 6；As Figure 2-3, seal structural part includes section in two neighboring convex
The sealing ring 4 of the recess portion 43 formed between portion and two protrusions (the first protrusion 41 and the second protrusion 42)；Sealing ring 4 is realized to set
Sealing ring 4 can also be referred to as Type B circle by the sealing of cylinder and outer inner room.Two protrusions and recess portion are to sleeve and outer inner room shape
At sealing, the sealing surface that top cap is pulled with jacket friction is compensated for, and summer high temperature environment lower seal expanded by heating, two pass are close
There are recessed gaps between cover, make up the volume of expansion, are not likely to produce oil leak and avoid generating reversion when installation top cap and cut
Oil leak caused by bad, and process, assemble fairly simple, cost is also relatively low.
For better seal, protrusion is semicircular structure, and the size of recess portion is not more than 0.5mm.Make between recess portion and protrusion
Sealing ring is obtained in the expansion space expanded by heating Shi Nengyou, avoids oil leak.
In order to avoid generating friction iron filings with outer inner room when seal structural part installation, the application carries out into one technical solution
Step is improved.
The cell wall outer diameter that annular groove 6 is bordered by end cover side is greater than the outer diameter that annular groove deviates from end cover side cell wall 5, to guarantee to rotate
Iron filings will not be generated when installation.
Although the utility model has been disclosed with preferred embodiment as above, so it is not intended to limit the utility model.This reality
It is without departing from the spirit and scope of the utility model, each when that can make with novel those of ordinary skill in the art
Kind changes and retouches.Therefore, the protection scope of the utility model is subject to view those as defined in claim.
