Description
Technical field
The utility model relates to the cooperations on a kind of automobile, and in particular to a kind of shockproof plunger.
Background technique
General plunger is in cylindrical shape, is mounted in cylinder body and does back and forth movement, since automobile can meet with often under steam
By the state of the strenuous vibration of moment, therefore plunger will receive the moment stress of left and right sidewall in back and forth movement, and especially one
More long automobile of a little service lives, piston plunger activity can have minim gap, and plunger motion can have small swing, automobile
After by high vibration, the abrasion that these moment stress can be very stiff and demanding with the generation of plunger influences the service performance of plunger, very
To the damage for leading to component.
Summary of the invention
To solve the above problems, a kind of the purpose of this utility model is to provide structures earthquake prevention column that is reliable, having buffering
Plug.
To achieve the above object, the utility model provides following technical solution: a kind of shockproof plunger, including chock plug, plug
Bar and plug sleeve, described chock plug one end are equipped with the stopper rod, and the plug sleeve inner hole is equipped with helicla flute, the helicla flute
A damping spring is screwed in, the length of the damping spring is greater than the plug sleeve, and the plug sleeve can live by the damping spring
It is dynamic to be socketed on the stopper rod, it is equipped with limit stop ring in the stopper rod end, one end of the damping spring is connected to institute
In the limit stop ring stated, the rudimentary one end in the chock plug of the other end, the outer diameter phase of the outer diameter of the chock plug and the plug sleeve
Match, configure the first sealing ring and the second sealing ring on the chock plug, first sealing ring and second sealing ring it
Between Separation control between 3mm ~ 5mm.
Separation control between the upper surface of the plug sleeve and the chock plug is between the mm of 4mm ~ 6, the plug sleeve lower end
Separation control between face and the limit stop ring is between 2 mm ~ 4mm.
It is additionally provided with cock body in the end of the stopper rod, the outer diameter of the cock body and the outer diameter of the chock plug match.
This structure of the utility model, for running car when encountering strenuous vibration, the plug sleeve on stopper rod is in damping spring
Under the action of, the buffering of instantaneous delay can be obtained, to avoid plug sleeve outer wall that very stiff and demanding abrasion occurs, improve the stabilization of work
Property and reliability, and chock plug is set in the end of stopper rod, which works together with plug sleeve, raising reliability of structure, this
Sample just realizes the technical effect that structure is reliable, has buffering.
The utility model is further described with reference to the accompanying drawings and detailed description.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of specific embodiment of the present invention.
Specific embodiment
As shown in Figure 1, present embodiment discloses a kind of shockproof plunger, including chock plug 1, stopper rod 2 and plug sleeve 3, chock plug 1 one
End is equipped with stopper rod 2, and 3 inner hole of plug sleeve is equipped with helicla flute, and helicla flute screws in a damping spring 4, and the length of damping spring 4 is greater than plug sleeve
3, plug sleeve 3 is socketed on stopper rod 2 by the way that the damping spring 4 is movable, is equipped with limit stop ring 5, damping spring 4 in 2 end of stopper rod
One end be connected in limit stop ring 5, the rudimentary one end in chock plug 1 of the other end, the outer diameter phase of the outer diameter and plug sleeve 3 of chock plug 1
Match, the first sealing ring 6 and the second sealing ring 7 are configured on chock plug 1, the interval control between the first sealing ring 6 and the second sealing ring 7
System is between 3mm ~ 5mm.
Separation control between the upper surface and chock plug 1 of plug sleeve 3 is between the mm of 4mm ~ 6,3 lower end surface of plug sleeve and limiting block
Separation control between circle 5 is between 2 mm ~ 4mm.Such design can make the buffering up and down of plug sleeve 3 provide enough spaces,
Improve the quality of buffering.
It is additionally provided with cock body 8 in the end of stopper rod 2, the outer diameter of the outer diameter and chock plug 1 of cock body 8 matches.The chock plug 1 and plug sleeve
3 work together, and can further improve reliability of structure,
This structure of the utility model, for running car when encountering strenuous vibration, the plug sleeve 3 on stopper rod 2 is in damping bullet
Under the action of spring 4, the buffering of instantaneous delay can be obtained, to avoid 3 outer wall of plug sleeve that very stiff and demanding abrasion occurs, improve work
Stability and reliability, and chock plug 1 is arranged in the end of stopper rod 2, which works together with plug sleeve 3, and that improves structure can
By property, the technical effect that structure is reliable, has buffering is just realized in this way.
