Abstract
The utility model relates to a sewer dredger which is suitable for families, hotels and guesthouses. The sewer dredger is composed of a corrugated pipe-shaped overlying cylinder, a pushing-pulling rod arranged at the sealing end of the overlying cylinder, a fixing ring arranged at the opening end of the overlying cylinder and a sealing ring. One end of the overlying cylinder is sealed, and the other end is opened. The utility model has the advantages of large operation pressure, good sealing, no splash, convenient use, etc.
Description
The utility model relates to a kind of sewer dredging device, is applicable to indoor water down such as family, hotel, hotel, dredges when urinal stops up and use.
The dynamic formula of existing Dredge device for sewer, the gentle cartridge type of leather cup formula etc., dynamical type dredging device are that helical spring is inserted water leak twist down, and its weak point is easily to spill foul in big valency height of body and the operation, is not suitable for indoor particularly family and uses; Leather cup formula dredging device is made up of pull bar and the leather cup that is installed in pull bar one end, and its weak point is, and is poorly sealed with following water leak during operation because leather cup is yielding, and it is little and outwards dabble easily to dredge pressure, not only required great effort but also effect bad; Inflator formula dredging device also exists bottom lock not tight, outwards dabbles and the flimsy problem of vent plug.
The purpose of this utility model is to provide a kind of mediation pressure big, with following water leak good seal performance, does not dabble, dredges effective and cheap dredging device.Technical solution of the present utility model is: main component is that the bellow-shaped that one one end seals an end opening laminates tube, and pull bar is installed at the blind end center that laminates tube, and its openend installs and fixes ring, and the sealing ring with following water leak sealing usefulness is installed on the retainer ring.
When using, the utility model compresses as long as retainer ring and sealing ring placed on the leak, then retainer ring strictly seals by sealing ring and following water leak edge, laminates tube by the pull bar compression again, pressure can be imposed on down water, the obstruction propelling is loosening, thus the mediation sewer pipe.
Advantage of the present utility model is, owing to adopt bellow-shaped to laminate tube as the compressed-air power part, volume is big, and operation amplitude is big, and the pressure that imposes on sewer pipe is big, dredge effectively, and general obstruction once just can be dredged; The utility model is that depended on pressure pushes obstruction downwards, and because of laminating the opening employing retainer ring and the sealing ring of tube, the elasticity of compression is moderate during operation, and is both indeformable, and it is good again to seal, air tight, do not dabble, sanitation and hygiene, and simple in structure, and cost is low, easy to use, be fit to very much indoor particularly family and use.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in detail.5 is that the utility model is used for the main component that compressed air produces pressure and laminates tube among the figure, and it is a upper end closed, and the working of plastics of the similar bellows structure of lower ending opening forms through blow molding.One end of pull bar 2 is fixed on the blind end that laminates tube 5, and its other end is installed and pushed handle 1.At the openend that laminates tube 5 retainer ring 6 that prevents its distortion is installed, the sealing ring 7 with following water leak edge sealing usefulness is installed on retainer ring 6.Present embodiment also is sleeved on the outside that laminates tube 5 to cylindrical outer casing 4, and one port is fixedlyed connected with retainer ring 6, and pull bar 2 stretches out outside the housing from the another port of shell 4, and this port of housing is to stay centre bore through reducing, is slidingly matched with pull bar.Shell 4 can be protected and laminate tube and be not damaged, and increases the appearance effect of dredging device.Limited block 3 is installed on pull bar 2 in addition, the last end in contact of limited block 3 and shell 4 when pull bar 2 is positioned at the lower position, promptly it limits the operation lower position by shell 4 upper end centre bores, damages by pressure laminating tube because of overexerting when preventing to operate.Retainer ring 6 of the present utility model and shell 4 usefulness metal material or plastics manufacturing, present embodiment is to be formed by injection molding with plastics.Sealing ring 7 usefulness rubber or foam plastic are made, and present embodiment is that foam plastic is made.In the present embodiment, bonded structure is adopted in the connection that laminates between tube, retainer ring, sealing ring, the shell, bonding with waterproof strong adhesive or chloroform, for bonding more firm, I shape is as shown in the figure made in the cross section of retainer ring 6, and the mouth limit that laminates tube and shell is inserted in the crack of I shape and used resin glue bonding, make this dredging device have compact conformation, attractive in appearance, light, characteristics such as durable.
