Basic components and accessory in the national economy main industries such as national defence, chemical industry, petroleum, coal, communications and transportation and machine-building,
Occupy considerable status in the national economic development.Sealing element can be divided into axis sealing by effect, hole seals, dust-proof close
Envelope, guide ring, fixing seal, rotary sealing；By by material can be divided into nitrile rubber, ethylene propylene diene rubber, fluorubber, silica gel,
Fluorine silicone rubber, nylon, polyurethane, engineering plastics etc..Wherein, Wellendichtring when in use, between motor shaft and sealing ring
Contact is face contact, since a degree of vibration can occur at runtime for motor shaft, between will existing between axis and sealing ring
Gap, sealing effect is bad, and if be changed to a basic structure, the vibration of axis can be seriously worn sealing ring, and sealing element uses the longevity
Life will be greatly reduced.
Utility model content
In view of the foregoing deficiencies of prior art, the purpose of this utility model is to provide a kind of axis plastic seals
Part for solving in the prior art due to the vibration of axis so that sealing effect is bad, and can wear sealing ring, reduce and use the longevity
The problem of life.
In order to achieve the above objects and other related objects, the utility model provides a kind of axis plastic seal, including upper
Fixed plastics part, sealing ring and lower fixed plastics part, on the axis of fixed plastic part, sealing ring and lower fixed plastics part
Axis hole is offered, is connected with fixed ring on the outside of the sealing ring, fixed sealing element and lower fixing seal are and institute
Fixed ring connection is stated, spacing collar is embedded on the inner sidewall of the sealing ring axis hole, is connected in the spacing collar by spring
Sealing ring is uniformly provided with groove on the inner sidewall of the sealing ring axis hole, rocker piece, the floating is equipped in the groove
The end of block is connect by spring with recess sidewall.
Preferably, it is equipped with internal screw thread on the outside of the coupling part of fixed plastic part and lower fixed plastics part, it is described
The inside of fixed ring is equipped with external screw thread, and fixed plastic part and lower fixed plastics part are threadedly coupled with the fixed ring.
Preferably, the quantity of the rocker piece is 4.
Preferably, fixed plastic part, sealing ring are identical with the pore size of the axis hole of lower fixed plastics part.
Compared with prior art, the utility model has the beneficial effects that by being equipped with elasticity in the axis hole of sealing ring even
The sealing ring and rocker piece connect, is all point contact between axis and sealing ring and rocker piece, improves sealing effect, and produce in axis
When raw vibration, can effectively buffer shaft to the pressure of sealing ring, reduce the abrasion to sealing ring, improve service life.
Detailed description of the invention
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing.
Fig. 1 is a kind of structural schematic diagram of axis plastic seal provided by the utility model；
Fig. 2 is the connection schematic diagram of the spacing collar and sealing ring in the utility model；
Fig. 3 is the connection schematic diagram of the rocker piece and sealing ring in the utility model；
Fig. 4 is a kind of scheme of installation of axis plastic seal provided by the utility model；
Wherein, appended drawing reference is described as follows: upper fixed plastics part 1, sealing ring 2, lower fixed plastics part 3, axis hole 4,
Fixed ring 5, spacing collar 6, sealing ring 7, rocker piece 8, internal screw thread 9, external screw thread 10.
Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book easily understands other advantages and effect of the utility model.
Please refer to Fig. 1-4.It should be clear that this specification structure depicted in this specification institute accompanying drawings, ratio, size etc., only to match
The revealed content of specification is closed, so that those skilled in the art understands and reads, being not intended to limit the utility model can
The qualifications of implementation, therefore do not have technical essential meaning, the tune of the modification of any structure, the change of proportionate relationship or size
It is whole, in the case where not influencing the effect of the utility model can be generated and the purpose that can reach, it should all still fall in the utility model institute
The technology contents of announcement obtain in the range of capable of covering.Meanwhile in this specification it is cited as "upper", "lower", "left", "right",
The term of " centre " and " one " etc. is merely convenient to being illustrated for narration, rather than to limit the enforceable range of the utility model,
Its relativeness is altered or modified, under the content of no substantial changes in technology, when being also considered as the enforceable scope of the utility model.
Refering to fig. 1-4, the utility model provides a kind of axis plastic seal, including upper fixed plastics part 1, sealing ring 2
With lower fixed plastics part 3, axis hole 4 is offered on the axis of upper fixed plastics part 1, sealing ring 2 and lower fixed plastics part 3, and
