Abstract
A kind of piston rod dustproof construction, it includes：Piston rod；It is fixed on connection hanger of the piston rod to one end；And dust shroud, dust shroud includes one and the vertically disposed circular substrate of piston rod, the extension for the tubular that the periphery of substrate is extended vertically and formed towards the side away from connection hanger, protuberance forms protrusion upwards at the middle part of substrate, through hole is offered at the center of protrusion, the connecting portion for the tubular that the hole wall edge of through hole is extended vertically and formed towards connection hanger side, the inwall of connecting portion mutually weld with piston rod.Its piston rod dustproof construction, mutually welded with piston rod by the connecting portion of tubular, and strengthen the structural strength of dust shroud by protrusion.Therefore piston rod dustproof construction intensity of the present utility model is higher, is not easy to loosen in use, service life is greatly improved.
Description
Technical field
It the utility model is related to vehicle shock absorber field, and in particular to a kind of piston rod dustproof construction.
Background technology
In vehicle shock absorber field, when producing vehicle shock absorber, dust shroud and piston rod dust shroud and piston rod
Between general mutually weld.Its shortcoming is that its weld strength is relatively low, during the use of shock absorber, easily causes to loosen, and then
Shock absorber is caused to damage.
The content of the invention
To solve the above problems, the utility model is directed to providing a kind of piston rod dustproof construction, make its structural strength it is high,
Service life is longer.
A kind of piston rod dustproof construction provided by the utility model, it includes：Piston rod；Piston rod is fixed on to one end
Connection hanger；And dust shroud, dust shroud include one and the vertically disposed circular substrate of piston rod, the periphery of substrate is towards remote
The extension for the tubular for extending vertically and being formed from the side of connection hanger, protuberance forms protrusion upwards at the middle part of substrate, grand
Through hole is offered at the center in the portion of rising, the hole wall edge direction of through hole connects the company for the tubular that hanger side extends vertically and formed
Socket part, the inwall of connecting portion mutually weld with piston rod.
Preferably, connecting portion mutually welds with being connected opposite one end of both hangers.
Preferably, piston rod dustproof construction of the present utility model, in addition to the dust proof tube being coaxially disposed with piston rod, prevent
Mutually welded with the outer wall in extension axial one end of the direction connection hanger of dirt cup.
Preferably, connecting hole is offered on one end end face of the remote connection hanger of piston rod.
Piston rod dustproof construction of the present utility model, it is mutually welded by the connecting portion of tubular with piston rod, and by grand
The structural strength of the portion of rising enhancing dust shroud.Therefore piston rod dustproof construction intensity of the present utility model is higher, is using process
In be not easy to loosen, service life is greatly improved.

Embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with accompanying drawing.In the utility model
Description in, it is necessary to explanation, term " " center ", " on ", " under ", "left", "right", " vertical ", " level ", " interior ", " outer "
Orientation or position relationship Deng instruction are based on orientation shown in the drawings or position relationship, are for only for ease of and describe this practicality newly
Type and simplifying describes, rather than instruction or implies that signified device or element must have specific orientation, with specific orientation
Construction and operation, therefore it is not intended that to limitation of the present utility model.In addition, term " first ", " second ", " the 3rd " are only used
In description purpose, and it is not intended that instruction or hint face ground importance.
, it is necessary to which explanation, unless otherwise clearly defined and limited, term " are pacified in description of the present utility model
Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integratedly
Connection；Can be mechanical connection or electrical connection；Can be joined directly together, can also be indirectly connected by intermediary,
It can be the connection of two element internals.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
Concrete meaning of the language in the utility model.
Please refer to Fig. 1, Fig. 2.
Piston rod dustproof construction of the present utility model, including：Connect hanger 1, dust shroud 2 and piston rod 3.Wherein, even
Connect axial one end that hanger 1 is fixed on piston rod 3.Dust shroud 2 includes one and the vertically disposed circular substrate 21 of piston rod 2.
The extension 22 for the tubular that the periphery of substrate 21 is extended vertically and formed towards the side away from connection hanger 1.The middle part of substrate 21
Protuberance forms protrusion 23 upwards.Through hole 24 is offered at the center of protrusion 23.Hung towards connection at the hole wall edge of through hole 24
The connecting portion 25 for the tubular that ear side extends vertically and formed.The inwall of connecting portion 25 welds with the phase of piston rod 3.Connecting portion 25 with
Mutually weld opposite one end of connection both hangers 1.
Piston rod dustproof construction of the present utility model, it is welded by the connecting portion 25 of tubular with the phase of piston rod 3, and is passed through
Protrusion strengthens the structural strength of dust shroud.Therefore piston rod dustproof construction intensity of the present utility model is higher, is using
It is not easy to loosen in journey, service life is greatly improved.
In some other embodiments, it is preferable that piston rod dustproof construction also includes one be coaxially disposed with piston rod 3
Dust proof tube 4.Mutually welded with the outer wall in extension 25 axial one end of the direction connection hanger 1 of dust proof tube 4.So, can be right
Piston rod plays more preferable dustproof effect.
In some other embodiments, it is preferable that offered on one end end face of the remote connection hanger 1 of piston rod 3
Connecting hole 30.So, the connection with piston (not shown) can be facilitated.
The non-detailed portion of other in the utility model belongs to prior art, therefore will not be repeated here.
Finally it should be noted that：Various embodiments above is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, either to which part or whole
Technical characteristic carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
The scope of each embodiment technical scheme of type.
