Abstract
The utility model belongs to a sealing piece, and in particular to a water seal for a washing machine, which overcomes the weaknesses of the prior water seal of the washing machine that the water seal is easy to deform when in assembling and is easy to lose effectiveness, and comprises an outer oil seal, wherein an inner oil seal is arranged inside the outer oil seal, the inner oil seal is reversely locked at the outer side of the outer oil seal, a seal auxiliary lip is arranged at the inner ring of the outer oil seal, one end of the outer ring is provided with a wave-resistant corrugation lip, the inner ring of the inner oil seal, i.e. one side of the inner oil seal facing towards a rotating shaft is provided with a seal main lip. By adopting the assembling-type structure, the installation strength of the oil seal is improved, the service life of the oil seal is prolonged, and the sealing effect is good.
Description
Technical field
The utility model belongs to a kind of seal, relates in particular to a kind of water seal that is used for washing machine.
Background technology
At present, the monomer seal is mostly adopted in the washing machine water seal, and its structure has only inner single support frame as shown in Figure 1 in this oil sealing, and intensity reduces, and causes the distortion of product during assembling easily, causes oil seal failure; In addition, the sealing lip lip of oil sealing can directly be subjected to the impact of washings, has destroyed the uniform potted line that the product lip forms, and causes internal lubrication fat to reveal easily, causes the oil sealing dry grinding to be lost efficacy.Therefore, when adopting the monomer seal as the washing machine water seal, be very easy to lose efficacy, service life is short, has influenced the serviceability of washing machine, has brought certain trouble for people's daily use.
Summary of the invention
Easy deformation when the purpose of this utility model is to overcome existing washing machine water seal assembling, and the defective that easily lost efficacy have proposed a kind of novel washing machine water seal, it has adopted fabricated structure, strengthen the installation strength of oil sealing, prolonged the service life of oil sealing, and good sealing effect.
The utility model is to adopt following technical scheme to realize: a kind of washing machine water seal, comprise outer oil seal, wherein, described outer oil seal inside is provided with an inner oil seal, the inner oil seal back-off is in the outer oil seal inboard, described outer oil seal inner ring is provided with the sealing pair lip, and corresponding outer ring one end is provided with wave resistance ripple lip, and the inner ring of inner oil seal promptly is provided with the main lip of sealing towards a side of rotating shaft.
In the utility model, the outer ring rubber of described outer oil seal and inner oil seal all has wave, and this wave makes oil sealing be convenient to install.
In this oil sealing, inner oil seal has played supporting role to outer oil seal, has strengthened the intensity of product, and is therefore not yielding when mounted.Main lip of sealing and sealing pair lip in this oil sealing is separately positioned on inner oil seal and the outer oil seal simultaneously, seals main lip and sealing pair lip and separately makes the servo-actuated of winner's lip better, improved the sealing effectiveness of water seal; The wave resistance ripple lip that is provided with on the outer oil seal has been blocked the impact of washings to lip, and therefore inner lubricating grease can not revealed because of the impact of washings, has played better sealing function.
The beneficial effects of the utility model are: fabricated structure is adopted in this laundry water seal, has strengthened the installation strength of water seal, and is not yielding when therefore installing; Improved the servo-actuated that seals main lip, blocked washings, made the sealing effectiveness of oil sealing better, and prolonged service life sealing the impact of main lip lip.
Description of drawings
Fig. 1 partly cuts open structural representation for existing washing machine water seal;
Fig. 2 partly cuts open structural representation for washing machine water seal in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 2, fabricated structure is adopted in this washing machine water seal, promptly is made up of outer oil seal 2 and inner oil seal 5, wherein inner oil seal 5 back-offs are in the inboard of outer oil seal 2, by the support of inner oil seal 5, improved the installation strength of outer oil seal 2, so this water seal is not yielding when installing.The inboard of outer oil seal 2 is provided with sealing pair lip 4, the corresponding outside one end is provided with wave resistance ripple lip 1, and this lip has been blocked the impact of washings to lip, and lubricating grease can not revealed because of the impact of washings, both guarantee the normal use of oil sealing, also improved its sealing effectiveness.The inboard of inner oil seal 5 promptly is provided with the main lip 4 of sealing towards a side of rotating shaft, by inside and outside oil sealing is set, main lip 4 and secondary lip 3 is separately positioned on inner oil seal 5 and the outer oil seal 2, makes the servo-actuated of winner's lip 4 better, has improved sealing.All have ripple on the outer ring rubber of inner oil seal 5 and outer oil seal 2, more help the installation of oil sealing.
Claims (2)
1. washing machine water seal, comprise outer oil seal, it is characterized in that: described outer oil seal inside is provided with an inner oil seal, the inner oil seal back-off is in the outer oil seal inboard, described outer oil seal inner ring is provided with the sealing pair lip, corresponding outer ring one end is provided with wave resistance ripple lip, and the inner ring of inner oil seal promptly is provided with the main lip of sealing towards a side of rotating shaft.
2. washing machine water seal according to claim 1 is characterized in that: the outer ring rubber of described outer oil seal and inner oil seal all has wave.
