Abstract
The utility model relates to a pipeline connecting piece structure which comprises a square pipeline joint flange and a circular pipeline joint flange deviating from the axis of the square pipeline joint flange. A connecting pipe is fixedly connected between the square pipeline joint flange and the circular pipeline joint flange. The connecting pipe comprises first connecting boards and second connecting boards, wherein the first connecting boards and the second connecting boards are mutually sealed and buckled and provided with opposite first side connecting walls formed in a necking mode from the sides of the square pipeline joint flange to the circular pipeline joint flange. The two sides of each first side connecting wall are respectively provided with an arc transitional portion formed in a necking mode from the circular pipeline joint flange to the corresponding corner of the square pipeline joint flange. The arc transitional portions located on the first connecting boards are connected with opposite second side connecting walls. The second side connecting walls and the arc transitional portions located on the second connecting boards are in butt joint and are sewn. According to the pipeline connecting piece structure, connection between a circular pipeline and a square pipeline can be achieved conveniently.
Description
Technical field
The utility model relates to pipe joint structure, relates in particular to a kind of for connecting the connecting-piece structure of circular pipe and square pipe.
Background technique
Pipeline of the prior art, in the laying of pipeline, only adopts a kind of pipeline of form conventionally, such as adopting the water pipe of circular pipe, the ventilation duct of employing square pipe etc.Yet in actual application, need sometimes circular pipe and square pipe to couple together, due to the pipeline property of there are differences of two kinds of forms, therefore implement comparatively difficulty.
Model utility content
The purpose of this utility model is to overcome the problem of above-mentioned prior art, and a kind of pipe joint structure is provided, and it can realize being connected between circular pipe and square pipe easily.
The purpose of this utility model is to be achieved through the following technical solutions:
Pipe joint structure, comprise square pipe flange and depart from the circular pipe flange of described square pipe flange axis, between described square pipe flange and described circular pipe flange, be connected with connecting tube, described connecting tube comprises the first connecting plate and the second connecting plate that mutual sealing fastens; Described the first connecting plate and described the second connecting plate have respectively the first relative side connecting wall forming to described circular pipe flange constriction from the limit of described square pipe flange; The both sides of described the first side connecting wall have respectively four arc-shaped transition portions that corner constriction forms to described square pipe flange from described circular pipe flange; The arc-shaped transition portion being positioned on described the first connecting plate is connected with respectively the second relative side connecting wall; Described the second side connecting wall docks stitching with the arc-shaped transition portion being positioned on described the second connecting plate.
Further, the opening area of described square pipe flange is greater than the area of described circular pipe flange.
Pipe joint structure described in the utility model, comprise square pipe flange and depart from the circular pipe flange of square pipe flange axis, between square pipe flange and circular pipe flange, be connected with connecting tube, connecting tube comprises the first connecting plate and the second connecting plate that mutual sealing fastens; The first connecting plate and the second connecting plate have respectively the first relative side connecting wall forming to circular pipe flange constriction from the limit of square pipe flange; The both sides of the first side connecting wall have respectively four arc-shaped transition portions that corner constriction forms to square pipe flange from circular pipe interface flange; The arc-shaped transition portion being positioned on the first connecting plate is connected with respectively the second relative side joint; The second side connecting wall docks stitching with the arc-shaped transition portion being positioned on the second connecting plate.By the pipe joint structure of this structure, realized easily being connected between circular pipe and square pipe.
