Description
Technical field
The utility model relates to bushing technical field more particularly to a kind of bushings being conveniently replaceable.
Background technique
Bushing is the auxiliary equipment for outside mechanical part, the effects of to reach sealing, abrasion protection, has referred to liner effect
Ring set.In valve application field, bushing, generally using anticorrosive materials such as polytetrafluoroethylene (PTFE) or graphite, is used within valve deck
In sealing function.In moving component, the abrasion of part is caused because of long-term friction, when axis and the gap wear in hole to one
Determine to have to renewal part when degree, therefore designer's selection hardness when design is lower, the preferable material of wearability
Material is axle sleeve or bushing, can reduce the abrasion of axis and seat in this way, when axle sleeve or liner wear are replaced to a certain extent, this
Sample can save the cost because of replacement axis or seat, and in general, bushing and seat are matched with axis using gap using interference fit
Close because no matter how or not can avoid abrasion, the service life can only be extended.
Existing bushing needs to be dismantled by cutting machine, iron hammer, spanner mostly in disassembly, dismantles laborious expense in this way
When, now need a kind of bushing being conveniently replaceable.
Utility model content
One proposed purpose of the utility model is to solve the shortcomings that being not easy to replacement existing in the prior art
The bushing that kind is conveniently replaceable.
To achieve the goals above, the utility model adopts the technical scheme that
Including liner body, the liner body is formed by interior main body, outer body combination, to extension at the top of the interior main body
Stretch and be inverted to form first annular groove, the interior main body bottom is fixed with first annular boss, the outer bottom part body to
Interior extension is simultaneously inverted to form second annular groove, and the outer body top is fixed with the second annular convex platform, the outer main body top
Second annular convex platform in portion is inserted into matched first annular groove, and the first annular boss of the interior main body bottom is inserted
Entering in matched second annular groove, the second annular groove bottom, which is fixedly mounted, to have elastic component, and described second
It is provided with the identical threaded hole of size being connected with interior main body portion at the top of annular convex platform, passes through spiral shell between the interior main body and outer main body
Nail is cooperatively connected with threaded hole.
Preferably, the elastic element is spring.
Preferably, it is provided with several groups oil groove in the interior main body inner wall surface, be provided on the liner body through main body
Through-hole, oil groove described in every group is connected with through-hole, and the number of the through-hole is two and is symmetricly set on liner body, described
The number of oil groove is at least two groups, interconnects between oil groove described in every group.
Preferably, the liner body outer surface is equipped with copper and tin silicon alloy layer.
The utility model proposes a kind of bushing being conveniently replaceable, beneficial effect is: in being connected by setting screw
Main body and outer main body, screw can be directly unloaded when dismantling bushing to separate outer main body with interior main body；Pass through setting
In second annular groove, interior main body outer main body can be released under the action of the spring after screw disassembling；Pass through setting
The oil groove being connected with through-hole, can the oiling into oil groove by through-hole, slow down the abrasion of bushing；By the way that liner body appearance is arranged
The copper and tin silicon alloy layer in face, can make entire bushing more resistant to corrosion.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of bushing being conveniently replaceable general illustration；
Fig. 2 be the utility model proposes a kind of bushing being conveniently replaceable top view.
In figure: liner body 1, interior main body 2, outer main body 3, first annular groove 4, the 5, second annular of first annular boss are recessed
Slot 6, the second annular convex platform 7, elastic element 8, threaded hole 9, screw 10, oil groove 11, through-hole 12.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, a kind of bushing being conveniently replaceable, including liner body 1 are designed, liner body 1 is by interior main body 2, outer
Main body 3 is composed, and is extended outwardly at the top of interior main body 2 and is inverted to form first annular groove 4,2 bottom of interior main body is fixed with
First annular boss 5, outer 3 bottom of main body extend internally and are inverted to form second annular groove 6, be fixed at the top of outer main body 3
Second annular convex platform 7 of the second annular convex platform 8, outer 4 top of main body is inserted into matched first annular groove 4, interior master
The first annular boss 5 of 2 bottom of body is inserted into matched second annular groove 6, the fixed peace in 6 bottom of second annular groove
Equipped with elastic element 8, elastic element 8 is spring, and it is identical that 7 top of the second annular convex platform with interior main body 2 is provided with connected size
Threaded hole 9, be cooperatively connected between interior main body 2 and outer main body 3 by screw 10 and threaded hole 9.
It is provided with several groups oil groove 11 in 2 inner wall surface of interior main body, the through-hole 12 through main body is provided on liner body 1, often
Group oil groove 11 is connected with through-hole 12, and the number of through-hole 12 is two and is symmetricly set on liner body 1,11 number of oil groove
