The utility model content
The technical problems to be solved in the utility model provides a kind of more convenient manual swan neck system that uses.
For solving the problems of the technologies described above, the manual swan neck system of the utility model comprises first fast pulley, second fast pulley, movable wheel and handle, first fast pulley is fixed on the base, second fast pulley is fixed on the described base, handle can be along center, the upper surface rotation of second fast pulley, and movable wheel is fixed on the described handle.
Preferably, the angle of a bevel protractor to show that pipe is bent is set on the base.
As the preferred version of such scheme, the zero graduation line of bevel protractor is arranged on the line of first fast pulley and the second fast pulley opposite face.
Preferably, on first fast pulley, second fast pulley and the movable wheel circular arc indent is set all, the circular arc indent on second fast pulley and the movable wheel matches and forms the cavity that can hold pipe.
Preferably, be respectively provided to few two circular arc indents on first fast pulley, second fast pulley and the movable wheel.
As the preferred version of such scheme, on first fast pulley, second fast pulley and the movable wheel two circular arc indents are set.
As the preferred version of such scheme, two circular arc indents are made as different sizes, to be suitable for the pipe of different tube diameters.
Preferably, first fast pulley, second fast pulley and movable wheel detachably are fixed on the described base, and second fast pulley, movable wheel are detachably connected on the described handle simultaneously.
After adopting such structure, structure is more compact, the bend pipe angle can directly directly be read by the bevel protractor on the base, the circular arc indent of double or many rows' different size can be the bending that is applicable to the pipe of different tube diameters, reduced the number of times of changing fast pulley and movable wheel, used more convenient.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, the manual swan neck system of the utility model comprises that first fast pulley 1, second fast pulley 2, movable wheel 3 and handle 4, the first fast pulleys 1 and second fast pulley 2 all are fixed on the base 6, and the two is at a distance of certain distance.One end of handle 4 links to each other with the center, upper surface of second fast pulley 2, and can be around this center rotation.The upper surface of movable wheel 3 is fixed on the handle 4, and the centre distance of movable wheel 3 and second fast pulley 2 is changeless.
In order to read the bend pipe angle behind the bend pipe easily, on base 6, a bevel protractor can be set, the zero graduation line of bevel protractor is arranged on the line of first fast pulley 1 and second fast pulley, 2 relative wheel rims.In use, pipe is passed between second fast pulley 2 and movable wheel 3, and not in the side of first fast pulley 1 near bevel protractor zero line 51.At this moment, pipe is just in time on the zero line of bevel protractor.As shown in Figure 1, turning handle 4 along clockwise direction, can read the angle that pipe is bent according to the reading of the sensing of the section of being bent pipe.
In order to reduce the problem of caliber distortion in the tube bending process, the circular arc indent 7 on circular arc indent 7, the second fast pulleys 2 that indent all is set on first fast pulley 1, second fast pulley 2 and the movable wheel 3 and movable wheel 3 matches and forms the cavity that can hold pipe.The radius of the circular arc indent 7 of the radius of pipe and second fast pulley 2, movable wheel 3 adapts.
As shown in Figure 1, on first fast pulley 1, second fast pulley 2 and movable wheel 3, at least two circular arc indents 7 are set all.A plurality of circular arc indents 7 on each fast pulley or the movable wheel 3 are set to different sizes.When the pipe of crooked different tube diameters, need not replacing activity wheel 3 and first, second fast pulley 1,2, use more conveniently, reduced the activity duration, improved operating efficiency.
In the factor of considering fast pulley and movable wheel 3 actual sizes and bending strength, the circular arc indent 7 of two different sizes is set on fast pulley and movable wheel 3 preferably.
In order to guarantee that the utility model can be suitable for the pipe of caliber in the 10-16mm scope, first fast pulley 1, second fast pulley 2 and movable wheel 3 detachably are fixed on the base 6, and second fast pulley 2, movable wheel 3 are detachably connected on the described handle 4 simultaneously.
The manual swan neck system of the utility model is fixed on two fast pulleys on the base 6 by two bearing pins, and second fast pulley 2 and activity wheel 3 links to each other by handle 4.During bend pipe, pipeline is passed between second fast pulley 2 and movable wheel 3, pipeline one head rest is on first fast pulley 1, move handle 4, make pipeline make circular motion, at pipe bending during to required angle around second fast pulley 2, stop to move handle 4, thereby reach the purpose of bend pipe.
Fast pulley, movable wheel 3 can be processed respectively together or the pipeline of the corresponding different tube diameters of twice, and it is right to organize flexibly during use, to adapt to the different tube diameters requirement.
Use this manual swan neck system can crooked Φ 10～Φ 16mm pipeline, can accomplish that with using with dress, flexible, this instrument is in light weight, it be slight to lighten one's labor, and has improved operating efficiency.
Above-mentioned design example only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substantial equivalence means that it may occur to persons skilled in the art that are all in the utility model claim scope.
