Abstract
The utility model relates to a hydraulic pressure skeleton dust ring, including metal framework, the dust ring that is connected with metal framework, being equipped with lip and oil groove on the dust ring, metal framework establishes the type into L including the first portion and the second portion that are connected, first portion, and the second portion is established to the barb form. The utility model discloses hydraulic pressure skeleton dust ring novel structure, sealed effectual, in use also is difficult for droing, distortion.
Description
Technical field
This utility model relates to sealing member, is specifically related to a kind of hydraulic pressure framework dustproof loop.
Background technology
Cylinders of Construction Machinery, long-term work and severe operating mode, therefore outside oil cylinder, arrange a dust ring prevent the impurity in the external world, dust, moisture etc. from entering sealing system thus destroy oil cylinder and ultimately result in oil cylinder and reveal, the problem that present framework dustproof loop shows is that lip enclasping force is inadequate, structural strength is inadequate, thus easily occurs that lip is extruded during causing using and ultimately result in product failure.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency overcoming prior art to be, it is provided that a kind of novel structure, good sealing effect, is in use not easy to come off, the hydraulic pressure framework dustproof loop of torsional deformation.
For solving above technical problem, a kind of technical scheme that this utility model is taked is:
A kind of hydraulic pressure framework dustproof loop, the dust ring being connected with metallic framework including metallic framework, dust ring is provided with lip and oil groove, and metallic framework includes first and second be connected, and first is set to
L
Type, second is set to barb-like.
Preferably, lip position is a mellow and full acute angle.
Preferably, oil groove is arranged to
V
Font, oil groove opening is less than
90
Degree.
Preferably, metallic framework forms an entirety with dust ring by the way of injection.
Preferably, metallic framework plugs with dust ring.
Preferably, the material of dust ring is polyurethane.
Due to the employing of above technical scheme, this utility model compared with prior art has the advantage that
Installation that the metallic framework of hydraulic pressure framework dustproof loop of the present utility model is dust ring provides rigidity, it is ensured that together with dust ring is closely installed at skeleton, is in use not easy to come off, torsional deformation, and additionally dust ring part contains oil groove, and the angle of oil groove is less than
90
Degree, main lip is that thickening type lip ensures that structure has the strongest anti-extrusion performance.

Effectively dust ring and metallic framework are combined, it is to avoid dust ring loosely comes off because of bonding with metallic framework.
In the present embodiment, lip
3
Position is a mellow and full acute angle, is so more beneficial for the raising of lip intensity, improves sealing property.
In the present embodiment, oil groove
4
It is arranged to
V
Font, oil groove
4
Opening is less than
90
Degree so that oil groove intensity becomes the highest, and lip root extension is more abundant, thus improves lip intensity.
In the present embodiment, metallic framework
1
With dust ring
2
Connected mode can by injection by the way of form an entirety, it is also possible to be set to metallic framework
1
With dust ring
2
Plug.
In the present embodiment, dust ring
2
Material be polyurethane.
This utility model hydraulic pressure framework dustproof loop novel structure, good sealing effect, be in use not easy to come off, torsional deformation.
Above this utility model is described in detail, all equivalence changes made according to this utility model spirit or modification, all should contain within protection domain of the present utility model。
