Abstract
The utility model discloses a pipeline extending unit which comprises a shell and rubber pipes. The shell is a step pipeline, the rubber pipes include the inner rubber pipe and the outer rubber pipe, the inner rubber pipe is arranged in the shell, one section of the outer rubber pipe is arranged in a large-aperture section of the step pipeline of the shell, the inner rubber pipe and the outer rubber pipe in the shell slidingly match with each other, another section of the outer rubber pipe is a corrugated pipe and is provided with an outer rubber pipe limiting flange at the end, and a limiting rod is arranged between the outer rubber pipe limiting flange and a shell limiting flange on the shell. The inner rubber pipe and the outer rubber pipe in the shell slidingly match with each other and are extensibly regulated, the outer rubber pipe outside the shell is the corrugated pipe and also extensibly regulated, and accordingly linear extension amount of the extending unit is increased greatly, the extending unit can be regulated only by adjusting the limiting rod, and the pipeline extending unit is simple to operate and flexible to extend.
Description
Technical field
The utility model relates to the pipe technology field, especially relates to a kind of pipeline extension device.
Background technique
Pipeline extension device is during pipeline connects because the coupling that the dimensional changes that causes of expanding with heat and contract with cold is recompensed avoids pipeline because of the distortion fracture of expanding with heat and contract with cold, and protects pipeline.
What existing pipeline extension device was commonly used has two kinds, and a kind of is the rubber tubing expansion bend, flexibly flexible, but the flexible compensation amount is little; Another kind is the metallic conduit expansion bend, and the flexible compensation amount is large, but flexible complicated operation.Existing pipeline extension device is difficult to realize simultaneously that the linear extendible amount is large and flexibly flexible.
The model utility content
Technical problem to be solved in the utility model provides a kind of pipeline extension device, to reach large, the flexible flexibly purpose of extending amount.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of pipeline extension device, comprise housing and sebific duct, described housing is the step pipeline, described sebific duct comprises interior sebific duct and outer sebific duct, interior sebific duct is located in the housing, one section of outer sebific duct is provided with in housing step pipeline heavy caliber section, interior sebific duct and outer sebific duct in the housing are slidingly matched, another section of outer sebific duct is provided with the spacing flange of outer sebific duct for bellows and in the end, is provided with position-limited lever between the spacing flange of housing on the spacing flange of described outer sebific duct and the housing.
The spacing flange of described housing is provided with retainer ring, is provided with seal rubber pad between the spacing flange of retainer ring and housing.
Be evenly equipped with three projections on the excircle of the spacing flange of described housing and the spacing flange of outer sebific duct, position-limited lever is located between corresponding projection.
The utility model compared with prior art, have the following advantages: interior sebific duct and outer sebific duct in the housing are slidingly matched, can carry out telescopic adjustment, one section outer outer sebific duct of housing is bellows, also can carry out telescopic adjustment, significantly improve the linear extendible amount of expansion bend, only need adjust position-limited lever during adjusting and get final product, simple to operate, flexibly flexible.
Description of drawings
The below makes brief description to the expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure:

Embodiment
The below contrasts accompanying drawing, by the description to embodiment, embodiment of the present utility model is described in further detail.
As shown in Figure 1, a kind of pipeline extension device comprises housing 2 and sebific duct, and housing 2 is the step pipeline of metal, is provided with housing adpting flange 1 at step pipeline small-caliber end, is provided with the spacing flange 3 of housing at step pipeline heavy caliber end; Sebific duct comprises interior sebific duct and outer sebific duct 7, and interior sebific duct is located in the housing 2, and interior sebific duct flange 9 and the housing adpting flange 1 of interior sebific duct outer end fit; 7 one sections of outer sebific ducts are provided with in housing step pipeline heavy caliber section, interior sebific duct and outer sebific duct in the housing are slidingly matched, outer sebific duct 7 another sections are provided with the spacing flange 5 of outer sebific duct for bellows and in the end, the corrugated pipe segment of outer sebific duct 7 is located at housing 2 outsides, and the outer sebific duct flange 8 of outer sebific duct 7 outer ends and the spacing flange 5 of outer sebific duct fit.Be provided with position-limited lever 6 between the spacing flange 3 of housing on the spacing flange 5 of outer sebific duct and the housing 2, easy to adjust.
Preferably, be provided with retainer ring 4 at the spacing flange 3 of housing, be provided with seal rubber pad between the spacing flange 3 of retainer ring 4 and housing, the seal rubber pad internal diameter guarantees sealing effect greater than the outer tube diameter of outer sebific duct 7.
Preferably, be evenly equipped with three projections on the excircle of the spacing flange 3 of housing and the spacing flange 5 of outer sebific duct, position-limited lever 6 is located between projection corresponding on the spacing flange of housing and the spacing flange of outer sebific duct, and is simple in structure, saves material, lightweight, easy for installation.
In model utility, the outer sebific duct of the sebific duct in the housing and housing all can carry out telescopic adjustment, has significantly improved the linear extendible amount of expansion bend, applied range.During adjusting, only need the length of the nut adjustment position-limited lever of rotary stopper boom end to get final product, simple to operate, flexibly flexible.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that design of the present utility model and technological scheme carry out; or without improving design of the present utility model and technological scheme are directly applied to other occasion, all within protection domain of the present utility model.
