Description

The collapsible swab of circular tower shape

This utility model relate to a kind of clear up floor drain etc. down weepage holes stop up the burnisher swab of usefulness.

The floor drain in the toilet of bathing pool in public places, lavatory, enterprises and institutions and family's toilet floor drain and various ponds such as washing basin, sink very easily stops up, contaminated environment, be extensive use of simple and easy common tool-swab that the cleaning floor drain stops up at present, for a long time, the shape that swab is taken out body all is that a round mouth is bowl-shape, make with reclaimed rubber, go into a rod as taking out bar taking out on the external body base skewer.When taking out the floor drain that body aim to stop up, firmly press down and take out bar, make and take out the intracoelomic cavity compression and cause negative pressure, pull up swab then tamper is extracted out, reach the purpose of block clearing.But main there are following several big shortcomings: the one, owing to take out the shape of body such as bowl-shape, not only compressible space is limited, draft is less relatively, and broken invalid very easily, often with several times even be for 1-2 time broken invalid.Be not durable very much again so draft is relatively little.The 2nd, take out bar and take out between the skewer hole on the body and only depend on the elastoplasticity of reclaimed rubber to be fixed together, therefore when upwards pulling up swab, very easily come off.The 3rd, it is wooden smoking bar, not only smooth being difficult for firmly, and waste timber.Be a size regardless of floor drain size swab simultaneously, a kind of color, both impracticable, not attractive in appearance again.

Purpose of design of the present utility model is to take out the shape and structure of body by change, makes to take out body and become circular tower shape folding, takes out bar and is made of plastics, and takes out body and takes out and tightened fixingly between the bar by the spiral shell button, and can add different dyes and makes the swab of different colours and increase aesthetic feeling; Also can make the serial swab of different size to increase applicability according to different places floor drain bore difference.Obviously change above-mentioned shortcoming, thus reach draft big, durable, take out body and take out bar and link firmly, be convenient to firmly, save timber, beautiful and applicable purpose.

The technical solution of the utility model is illustrated with shown in Figure 1.Fig. 1 is for facing generalized section.The part of this swab is the same with common swab, by taking out body 1 and taking out bar 2 and form.One of technological improvement of the present utility model is to be changed into circular tower shape and be the foldable body wall 3 of taking out by bowl-type taking out body 1, folding level what do not limit (generally more than 3 layers below 7 layers for well), can make the cavity of taking out body 1 be compressed to minimum, it is maximum that negative pressure reaches, then draft big (test factually, its draft is more than 10 times of general swab); Two of technological improvement of the present utility model is to take out body 1 to add the sulfuration of an amount of former raw rubber and auxiliary material (as carbon black) by reclaimed rubber and form, and increases the toughness and the intensity of taking out body 1, and its folding is drawn.Experiment showed, that can reach more than 20 trainings of common swab the service life that increases the swab behind a small amount of former rubber; It is fixing that three of technological improvement of the present utility model is that the end that will take out bar 2 band spiral shell buttons and the tapped bar hole, top 4 of taking out body 1 are tightened, and avoids taking out when firmly smoking body 1 and take out bar 2 and come off; Four of its technological improvement is to be made by polyvinyl chloride blowing taking out bar 2, and is shaped to the ring shaped thread 5 of band convex-concave at an upper portion thereof, takes out frictional force between bar 2 and the hand with increase, is convenient to firmly.Simultaneously save timber again, can use (promptly after taking out body 1 damage, can purchase separately and take out body 1, the former bar 2 of taking out can continue to use) again repeatedly.

This utility model production technology is simple, circular tower shape is collapsible takes out body 1 and takes out all one-shot formings in process of production of bar 2, simultaneously, also can be according to floor drain bores such as bathing pool, lavatories big and washing basin, characteristics that sink floor drain bore is little, make and take out body bore difference, series of products that color is different, both suited measures to local conditions, economical with materials is attractive in appearance again, practical.
