Abstract

The utility model discloses a water-leakage prevention device of a barrel washing machine, which comprises a tripod, a rotating shaft and an obturating ring, wherein a through hole used for installing the rotating shaft is arranged in the middle position of the tripod; the tripod used for supporting an internal barrel of the barrel washing machine is sleeved on the rotating shaft through the through hole; the obturating ring is arranged at the joint part between the tripod and the rotating shaft; a first convex rib is arranged at the periphery of the through hole of the tripod; and a second convex rib which is adapted with the first convex rib is arranged on the circumference of the obturating ring. The utility model can prevent water in the internal barrel from leaking from the rotating shaft and prolong the service life of the washing machine.

Description

The roller washing machine leakage-proof apparatus

Technical field

The utility model relates to a kind of roller washing machine parts, specifically a kind of roller washing machine leakage-proof apparatus that prevents that bucket leaks in the roller washing machine.

Background technology

Roller washing machine is owing to little to the infringement of washings of water saving characteristics have obtained extensive use.Roller washing machine is in washing and dehydration, and in the bucket, interior bucket was connected with motor by rotating shaft in washings was placed on, and by the rotation at a high speed of bucket in the driven by motor, thereby realizes washing and dehydration.Because the existence of washing weight and interior bucket own wt, installation reliability for bucket in guaranteeing, adopt tripod that interior bucket is fixed in the rotating shaft in the existing washing machine, during work, driven by motor tripod and the rotation of interior bucket one superhigh speed, tripod internally bucket plays fixing and supporting role, and bucket can steadily rotate in making.

The tripod that uses is seen Fig. 1 at present, and tripod 1 is made up of three supporting legs of central region and outwards stretching, extension, and three supporting legs evenly distribute along circumferentially being 120 degree, and the cross sectional shape of three supporting legs is rectangle.In the centre of tripod central region, be provided with the through hole that is used for installing machine shaft.The mounting groove shape of the shape of tripod and washing machine inner tub bottom is suitable, and the front of tripod and the mounting groove of washing machine inner tub are combined closely.Be generally the saving cost, also for alleviating the tripod deadweight, adding man-hour simultaneously, be provided with groove along three supporting leg directions; Be to guarantee the intensity of tripod, be provided with one group of reinforcement, so both saved material, reduced cost, guaranteed the intensity that tripod is enough simultaneously again at the another side of tripod.Washing machine for the water in the bucket in preventing permeates away from rotating shaft, is provided with sealing ring 3 at

tripod

1 and 2 of rotating shafts in the running, and sealing ring 3 separates washing machine inner tub and outside, and the water in making in the bucket can't permeate away from rotating shaft.Existing ring structure is seen Fig. 2.

Match with the rotating shaft shortcoming of structure of existing this sealing ring, tripod is: sealing ring can't seal when rotating shaft runs up fully, causes low amounts of water from the rotating shaft seepage, and roller washing machine is produced harmful effect.

Summary of the invention

For the water in the bucket in preventing permeates away from rotating shaft, the purpose of this utility model provides a kind of roller washing machine leakage-proof apparatus, and the water in this leakage-proof apparatus can be stopped in the bucket leaks out from rotating shaft, has prolonged the service life of washing machine.

The purpose of this utility model is achieved through the following technical solutions:

A kind of roller washing machine leakage-proof apparatus comprises tripod, rotating shaft and sealing ring, is provided with the through hole that is used for installing rotating shaft in the centre position of tripod; Being used for the tripod of back-up roller washing machine inner tub is sleeved in the rotating shaft by through hole, and sealing ring is arranged on the junction of tripod and rotating shaft, it is characterized in that: be provided with first fin around the through hole of tripod; On the circumference of sealing ring, be provided with second fin suitable with first fin.

In the utility model, the diameter of second fin on the sealing ring should be slightly larger than the diameter of first fin; The height of second fin is identical with the height of first fin, or the height of second fin is slightly larger than the height of first fin.After being installed in the rotating shaft like this, second fin cooperates tightly with first fin, makes water be difficult to enter sealing ring and rotating shaft institute contact position, spills from here thereby reduce water.

Compared with prior art, the utility model improves the washing machine hermetically-sealed construction, increases a circle first fin on the tripod sealing ring, simultaneously also corresponding increase by one circle second fin on the sealing ring of side within it.In washing machine when running,, first fin and second fin on the sealing ring in the tripod rotation process on it are discharged water outside, make water be difficult to enter sealing ring and rotating shaft institute contact position, thereby minimizing water spill from here.

The specific embodiment

A kind of roller washing machine leakage-proof apparatus described in the utility model comprises tripod 11, rotating shaft 12 and sealing ring 13, is provided with the through hole 111 that is used for installing rotating shaft 12 in the centre position of tripod 11; Being used for the tripod 11 of back-up roller washing machine inner tub is sleeved in the rotating shaft 12 by through hole 111, and sealing ring 13 is arranged on the junction of tripod 11 and rotating shaft 12, is provided with first fin 112 around the through hole 111 of tripod 11; On the circumference of sealing ring 13, be provided with and the second suitable fin 132 of first fin 112.

The diameter of second fin 132 on the sealing ring 13 should be slightly larger than the diameter of first fin 112; The height of second fin 132 is slightly larger than the height of first fin 112.After being installed in the rotating shaft 12 like this, second fin 132 cooperates tightly with first fin 112, and the water in making in the bucket is difficult to enter sealing

ring

13 and 12 contact positions of rotating shaft, spills from here thereby reduce water.

The water that the utility model has been stopped in the interior bucket leaks out from rotating shaft, has prolonged the service life of washing machine.
