Abstract

The utility model describes a kind of water string, has tubular body (1), and on the inwall of body (1), coaxial line is interval with annular groove (2), and on the outer wall of this body (1), coaxial line is interval with ring tenon (3).Be inserted in during use in pipe, be then sleeved on pipeline corresponding to floor gap place, be namely stuck in obtain between floor and soil stack pipeline and seal, solidify, locate, make the combination between floor and soil stack pipeline more firm.This sleeve pipe: 1, adopt inner groove outer shroud tenon structure to improve sealability and its rotproofness is improved; 2, body axial length is not limited also can be multistage, therefore user can cut randomly according to use length, not only facilitates user but also make waterproofing effect more reliable; 3, to be conducive to stuffing sleeping steady for the recessing of internal surface of sleeve pipe institute; 4, with low cost, easy for installation, reliable performance.

Description

Water string

Technical field

The utility model belongs to draining equipment technical field, is specifically related to a kind of for preventing drainage pipe from installing the water string revealed.

Background technique

In construction, toilet plumbing standpipe needs passing through floors to cause floor gap, brings leakage hidden danger.Traditional leakage-preventing i.e. waterproof means arrange a water string on the Pipe installing that floor gap place is corresponding, and code requirement is rigid casing or plastic bushing.Wherein rigid casing cuts off by steel pipe the water stop ring sleeve pipe be welded, and the defect of this sleeve pipe is, because the wet environment of toilet has corrosivity to steel, therefore can cause perforating steel pipe, thus namely use loses waterproof ability soon.And plastic bushing is directly cut by plastic tube to form, centre is not implemented gap welding thus is not also formed effective water stop ring structure, therefore thisly moulds that sleeve pipe processed is more difficult waterproof guarantee.

Summary of the invention

The technical problems to be solved in the utility model is, for overcoming the defect that above-mentioned known technology exists, a kind of water string of improvement is provided, when this water string uses, complementarity closed means need not be added can reach and prevent drainage pipe from the object revealed being installed, settle at one go and realize the seamless floor of soil stack and pass through.

The technical solution of the utility model is, described water string, and see Fig. 1, have tubular body 1, its technical characterstic is, on the inwall of described body 1, coaxial line is interval with annular groove 2, and on the outer wall of this body 1, also coaxial line is interval with ring-shaped step and ring tenon 3.

When being used by the water string of the present utility model formed above, can the rubber bush that size is mated with its inwall be inserted in pipe, then this water string of cover rubber sleeve cylinder is sleeved on pipeline corresponding to floor gap place, is namely stuck between floor and soil stack pipeline.Due to the body 1 outer wall barrel mast of such as this water string above-mentioned having ring tenon 3, therefore make both to have obtained good sealing effect between floor and soil stack pipeline, again because the setting of ring tenon 3 adds the friction factor between floor and soil stack pipeline thus obtains good solidification effect.On the other hand, because body 1 inwall also as this water string above-mentioned has coaxial line annular groove 2, this just makes above-mentionedly to be inserted in rubber bush in pipe and to stretch and form groove tooth with vallecular cavity in the vallecular cavity of annular groove 2 under external force extruding and rub, not only make rubber bush be located, also make the combination between floor and soil stack pipeline more firm.

The beneficial effects of the utility model are:

1, adopting inner groove outer shroud tenon structure to improve sealability makes its rotproofness be improved;

2, body axial length is not limited also can be multistage, therefore user can cut randomly according to use length, not only facilitates user but also make waterproofing effect more reliable;

3, to be conducive to stuffing sleeping steady for the recessing of internal surface of sleeve pipe institute;

4, with low cost, easy for installation, reliable performance.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model water string specific embodiment, is denoted as in figure:

1-body,

2-annular groove,

3-ring tenon.

Embodiment

Embodiment 1, and see accompanying drawing 1, this embodiment of the utility model water string commercially available thickness of drawing materials is that the high-quality steel tube profile of 10mm is tailored into tubular body 1, diameter 60mm, long 70mm.On the inwall of this body 1, coaxial line interval turnery processing goes out annular groove 2, annular groove 2 dark 2mm, wide 6mm, annular groove 2 interval 15mm; On the outer wall of this body 1, coaxial line interval turnery processing goes out ring tenon 3, the high 2mm of ring tenon 3, wide 2mm, ring tenon 3 interval 10mm.

The water string of the present utility model formed thus is proved to be Be very effective through manufacturing experimently to try out, and reaches designing requirement completely.User on probation is generally reflected well, creates significant economic benefit and social benefit.

Claims (1)

1. a water string, has tubular body (1), it is characterized in that, on the inwall of described body (1), coaxial line is interval with annular groove (2), and on the outer wall of this body (1), coaxial line is interval with ring tenon (3).
