Abstract
A double dust prevention lip sclerotization oil seal for a barrel washing machine comprises a rubber body and a metal ring skeleton embedded into the rubber body, wherein the blade tail of the rubber body is provided with a main dust prevention lip, and the bottom of the rubber body is sequentially provided with a first sealing lip and a second sealing lip; the blade tail is also provided with an auxiliary dust prevention lip; and the auxiliary dust prevention lip and the main dust prevention lip are arranged at intervals along the axial direction of the oil seal on the blade tail. The utility model solves the problems that dust and other sundries are easy to enter a sealing area, and the sealing reliability is reduced because the prior washing machine has a single dust prevention structure.
Description
Technical field
The utility model relates to a kind of household electrical appliance potted component, relates in particular to the two dust excluder lips outside framework oil seals of a kind of roller washing machine.
Background technology
Outside framework oil seal is the key position of machinery, and the quality of outside framework oil seal quality and performance is directly connected to sealing, security and the reliability of machine.
In domestic electric appliance, often can use some outside framework oil seals, as the normal outside framework oil seal (also can be described as rotary shaft lip seal) that uses between the inner core rotating shaft of tumbling-box washing machine and the bearing support block, this outside framework oil seal shape ringwise, as shown in Figure 1, mainly by rubber body 1, quoit skeleton 2 and turn 3 are formed, be provided with the leaf tail on the sealing surface of rubber body 1 from top to bottom successively, waist and bottom, on the leaf tail of rubber body 1, be provided with main dust excluder lips 4, main dust excluder lips 4 fits tightly with rotating shaft, in order to prevent the extraneous dust and the intrusion sealing area of foreign material, and on the leaf tail, also be provided with turn 3, this turn 3 is against on the rotating shaft main dust excluder lips 4, urgent power radially is provided, makes its end face seal; Be provided with first sealing lip 5 and second sealing lip 6 in the bottom of rubber body 1, leak in order to prevent other liquid mediums such as washing powder water.
Above-mentioned outside framework oil seal is provided with two sealing lips (first sealing lip 5 and second sealing lip 6) in the bottom of rubber body 1, effectively solved the problem that other liquid mediums such as washing powder water leak, but only being provided with a main dust excluder lips 4 at the leaf afterbody of rubber body 1 cooperates with the inner core rotating shaft, after long-time cooperation running, main dust excluder lips wearing and tearing occur and can't play the dustproof effect, thereby dust and other foreign material enter sealing area in the bearing support block hole, thereby reduced the reliability of sealing, after long-term the use, damage easily other part in the device for washing machine, to the dismounting aspect of electric equipment also having caused inconvenience.
Therefore, the utility model provides a kind of roller washing machine with two dust excluder lips outside framework oil seals, to remedy deficiency of the prior art from improving the prior art angle.
Summary of the invention
The utility model provides a kind of roller washing machine two dust excluder lips outside framework oil seals, its purpose mainly is to solve existing use in washing machine outside framework oil seal to adopt single dust excluder lips structure, makes dust and other foreign material enter the problem of sealing area, reduction sealing reliability easily.
For achieving the above object, the technical solution adopted in the utility model is: the two dust excluder lips outside framework oil seals of a kind of roller washing machine, comprise rubber body and be embedded in the interior quoit skeleton of rubber body, the leaf tail of rubber body is provided with main dust excluder lips, the bottom of rubber body is provided with first sealing lip and second sealing lip, also be provided with auxiliary dust excluder lips on the described leaf tail, this auxiliary dust excluder lips and main dust excluder lips are provided with at leaf tail upper edge oil sealing axially spaced-apart.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described auxiliary dust excluder lips is disposed on the top of main dust excluder lips vertically, and when assembling was used, the inclined-plane of auxiliary dust excluder lips and rotating shaft fitted tightly.Described " top " refers to the top as shown in Fig. 2, Fig. 4.
Because the technique scheme utilization, the utility model compared with prior art advantage is:
1, because the utility model axially sets gradually two dust excluder lips at the leaf tail upper edge of rubber body oil sealing---auxiliary dust excluder lips and main dust excluder lips, wherein, auxiliary dust excluder lips is axially disposed within the top of main dust excluder lips along oil sealing, in use, outside auxiliary dust excluder lips is blocked in dust in the bearing support block hole or other foreign material earlier, to reduce the load of main dust excluder lips, so just effectively avoided in the bearing support block hole dust or other foreign material to enter sealing area, dustproof effect has been played the effect of dual fail-safe, remedied and had only single main dust excluder lips to cooperate in the prior art with rotating shaft, after long-time running, main dust excluder lips wearing and tearing occur and can't play the deficiency of dustproof effect.
2, because the utility model axially sets gradually two dust excluder lips at the leaf tail upper edge of rubber body oil sealing---auxiliary dust excluder lips and main dust excluder lips, make the sealing reliability of this outside framework oil seal improve greatly, prolonged its service life, simultaneously also prolonged the service life of other pieces of equipment, the feasible also corresponding minimizing of frequency of changing potted component and equipment part.The household electrical appliance such as roller washing machine that the utility model is particularly useful for is multi-functional, apparatus is complete.
