Abstract
A waterproof dustproof ring comprises a body, wherein a main lip and a notch are arranged on the body, and vice-lips are arranged on groove walls of the notch. After installation of the waterproof dustproof ring, the vice-lip and a contact portion of an installation part have certain magnitude of interference so that the vice-lip and the installation part can be attached to each other closely and good waterproof and dustproof functions are achieved.
Description
Technical field
The utility model relates to Sealing, particularly a kind of dust ring that possesses water-proof function.
Background technique
Therefore engineering machinery oil cylinder, long-term work are provided with a dust ring and prevent that entering systems such as extraneous impurity, grieshoch, moisture from destroying oil cylinder and sealing system in abominable operating mode outside oil cylinder; Existing dust ring is only paid attention to the water proof and dust proof of dust ring and piston rod surface of contact; And ignored the effect of product outer ring water proof and dust proof, and existing dust ring does not have special water proof and dust proof lip design with the junction that groove is installed, and waterproofing effect is relatively poor; There is moisture to get into oil cylinder unavoidably from groove is installed; Special in the bigger environment of humidity, existing dust ring water-proof performance is poor, can not prevent effectively that extraneous moisture from getting into oil cylinder or sealing system.
The model utility content
In order to address the above problem, the utility model provides a kind of water proof and dust proof circle, comprises body, and body is provided with main lip and notch, and the cell wall of notch is provided with secondary lip.
One side channel wall of said notch is provided with secondary lip.
All be provided with secondary lip on the both sides cell wall of said notch.
Said secondary lip also can be in the outside of dust ring.
The lip of said secondary lip is thin at the bottom of than lip.
After the water proof and dust proof circle installation of the utility model, there are certain magnitude of interference in the secondary lip in the notch and the contacting part of assembling set, make secondary lip and assembling set in the notch fit tightly good water proof and dust proof effect.
Description of drawings
Fig. 1 is the utility model water proof and dust proof coil structures schematic representation.
Fig. 2 is another structural representation of the utility model water proof and dust proof circle.
Fig. 3 is the scheme of installation of the utility model water proof and dust proof circle.
Embodiment
Below in conjunction with accompanying drawing the utility model is described.
Embodiment 1
See also Fig. 1, the utility model water proof and dust proof circle comprises the main lip 2 of body 1, and body 1 is provided with notch 3, and a side of notch 3 and the outside of water proof and dust proof circle are provided with secondary lip 31.
See also Fig. 2, the utility model water proof and dust proof circle comprises the main lip 2 of body 1, and body 1 is provided with notch 3, and the both sides of notch 3 are provided with secondary lip 31.
During installation, the notch on the body 13 is pressed into the joint 41 that groove 4 is installed, because there are certain magnitude of interference in secondary lip 31 and 41 of joints; Therefore, secondary lip 31 fits tightly with joint 41, and the utility model is provided with main lip 2 body 1 master; Prevent that dust and moisture from getting into from piston rod; Secondary lip 3 also is set in notch 3, thereby prevents that dust and moisture from getting into from groove 4 is installed, the water proof and dust proof effect is splendid.
The above-mentioned disclosed specific embodiment that is merely the utility model, but the utility model is not limited thereto, any those skilled in the art can think variation, all should drop in the protection domain.
Claims (5)
