Description
Technical field
Hydraulic cylinder sealing technical field is the utility model is related to, specifically a kind of hydraulic cylinder fixes dress with framework dustproof loop
Put.
Background technology
Hydraulic cylinder is hydraulic energy is changed into mechanical energy to do straight reciprocating motion through commonly used in hydraulic system（Or swing
Motion）Hydraulic actuator.One of the main element of dust ring as hydraulic cylinder sealing device, playing prevents outside hydraulic cylinder
The effect that enters inside hydraulic cylinder of the dirt such as dust, sand-lime, rainwater and frost.Dust ring is generally fixed to hydraulic cylinder guide sleeve
Fixed on internal groove either using metal collar or using external metallization baffle plate.
As shown in Figure 1 to Figure 3, framework dustproof loop is fixed frequently with monoblock type baffle plate in the prior art.Baffle plate is
Thin slice ring-type, monoblock type, it is some to be uniformly distributed hole on baffle plate, by screw-driving, baffle plate right side plan with it is flat on the left of guide sleeve
Face is bonded, and dust ring is fixed in hydraulic cylinder guide sleeve groove.Which baffle plate is is integrally machined, to machining accuracy
It is required that high, cost is higher, while baffle plate easy-to-rust.The region formed between dust ring, baffle plate and piston rod outer surface is easy
Cause dust to save bit by bit, influence dust ring service life.
Therefore, the problem of existing framework dustproof loop technique for fixing is present be：
Baffle plate is overall cyclic formula, and machining accuracy is higher, and cost is high, and volume is big, uses easy-to-rust after a period of time；Anti-
The annular region formed between konisphere, baffle plate and piston rod outer surface（A-quadrant）Inside easily cause dust to save bit by bit, the powder in this region
Dirt can not remove；Lengthening over time, the density of the dirt in the region can be increasing, has a strong impact on that dust ring lip is prevented
Dirt effect, influence dust ring service life.
The content of the invention
In order to solve the above technical problems, the utility model provides a kind of hydraulic cylinder framework dustproof loop fixing device.
The utility model is achieved through the following technical solutions：A kind of hydraulic cylinder framework dustproof loop fixing device, including lead
To set；Groove is provided with the inside of the guide sleeve end face；Dust ring is installed in guide sleeve groove；It is characterized in that：The guiding
Set end face is provided with multiple uniform screw holes, and screw is provided with guide sleeve screw hole；Plain washer is installed on the screw；Institute
Plain washer edge is stated to be pressed on the outside of dust ring.
It is further：The plain washer is anti-skid washer.
An arc notch is provided with the plain washer edge.
Compared with prior art, the beneficial effects of the utility model are：
（1）It is simple in construction：Standard component screw and standard component plain washer are only needed, cost is low, small volume；
（2）Easy installation and removal：Threaded connection is fixed, easy to disassemble and replacing；
（3）Contact area is small, reduces sand and dust accumulation：Carried out by the way of plain washer is uniform it is spacing, outside dust ring lip
Side is naked to be exposed on the outside, and dust gets a promotion without the space accumulated, dust-proof effect；
（4）It is easily installed, it is only necessary to which pincers processing drilling eliminates the trouble of high accuracy machining manufacture, only needs standard component spiral shell
Nail and plain washer can be achieved with, easily manufactured, and cost significantly reduces, while easy to disassemble and replacing.

Embodiment
It is specific embodiment of the utility model below, the utility model is described further in conjunction with accompanying drawing.
Embodiment one
As shown in Figures 4 to 6, a kind of hydraulic cylinder framework dustproof loop fixing device, the end face of guide sleeve 1 inner side are provided with step
The groove of shape.Dust ring 2 is installed in the groove of guide sleeve 1.The end face of guide sleeve 1 is provided with multiple uniform screw holes, the spiral shell of guide sleeve 1
Screw 3 is installed in nail；Plain washer 4 is installed on screw 3；The edge of plain washer 4 is pressed in the outside of dust ring 2, ensures dust ring 2
Can not be along piston rod direction play.The outer end of dust ring 2 is in open, reduces dust accretions.Plain washer 4 is also alternatively into it
His shape thin slice is spacing to carry out.
Embodiment two
As shown in fig. 7, the difference of the utility model embodiment two and embodiment one is：Plain washer 4 uses anti-skid washer, spiral shell
After nail 3 is tightened, plain washer 4 is not susceptible to rotate.An arc notch is provided with the edge of plain washer 4, so, when the arc of plain washer 4
When v notch v is relative with dust ring 2, dust ring 2 can be changed in the case where screw 3 and plain washer 4 are not removed, be easy to anti-
The maintenance of konisphere 2.
