The technical solution adopted in the utility model is:
The hinge structure of folding heating device, it is characterized in that: described hinge structure comprises two articulated joints on two heater frameworks that are separately fixed at folding heating device, and the hinged cover hinged with described two articulated joints simultaneously, two articulated joints are about the vertical center line symmetric arrangement of hinged cover;
Each articulated joint comprises that one vertically is fixed on the fixed plate on the heater framework, and the gear shaft, the passing spool that vertically are arranged in these fixed plate top and bottom respectively, described gear shaft and passing spool coaxial arrangement and all make the tubular structure that is beneficial to wiring, one gear is fixedly arranged on the gear shaft, and the gear in two articulated joints is meshing with each other to guarantee stability of rotation;
Described hinged cover is spliced by fore shell, back cover, fore shell and back cover respectively are shaped on two half-cylindrical concave surfaces that vertically stretch, the half-cylindrical concave surface of fore shell and the half-cylindrical concave surface of back cover are in opposite directions and to arranging, the splicing back forms two hinging holes of vertically arranging, gear shaft, the passing spool of an articulated joint is installed respectively in each hinging hole; The middle part of two hinging holes is connected by cable-through hole and is beneficial to wiring.
Described fore shell and back cover are fastenedly connected mutually by screw.
Described fixed plate is fixed in the draw-in groove of heater framework.
Be shaped on the semi-cylindrical recesses that along continuous straight runs stretches on described fore shell and the back cover respectively, the semi-cylindrical recesses of two levels to arranging, forms described cable-through hole in opposite directions after the splicing.
In the described hinge structure, the central point line of two gear shafts and the symmetrical center line angle of one of them heater framework are α, the central point line of two gear shafts and the symmetrical center line angle of another heater framework are β, and the numerical value of angle α equates all the time with angle β.
Working principle of the present utility model is: two articulated joints are separately fixed on two heater frameworks, and hinged cover is simultaneously hinged with two articulated joints, makes two heater frameworks link together; When rotating, because the gear of two gear shafts meshes together the rotation (angle of the central point line of two gear shafts and the symmetrical center line of one of them heater framework, all the time equal the angle of the symmetrical center line of the central point line of two gear shafts and another heater framework), therefore can guarantee the stationarity of rotating; And power line penetrates from a passing spool wherein, afterwards through a hinging hole, cable-through hole enter another hinging hole (wire structures similar " several " font), pass from another passing spool again, can be unaffected when framework rotates and continued power, and it is inner that electric wire all is positioned at hinged cover, beautiful shape.
The beneficial effects of the utility model are: described hinge structure meshes by gear, guarantee the stationarity of rotation, and utilize passing spool and the cable-through hole of tubulose dexterously, make power line can Hide All in hinged cover and do not expose, beautiful shape, simultaneously by two gear engagements, make power line not be subjected to the influence that framework rotates, can excessively do not stretched and influenced electric property, guarantee the proper functioning of heating device, simple in structure, easy to use, cost is also cheaper, has market prospects preferably.

Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in the figure, the hinge structure of folding heating device, comprise two articulated joints on two heater frameworks 1 that are separately fixed at folding heating device, and simultaneously hinged with described two articulated joints hinged cover 3, two articulated joints are about the vertical center line symmetric arrangement of hinged cover, hinged cover with two articulated joints link together, thereby make two heater frameworks connect together and can relatively rotate.Usually, being provided with at least two hinge structures between two heater frameworks is beneficial to rotate and keeps stable.
Above-mentioned each articulated joint comprises that a fixed plate 2-4(fixed plate that vertically is fixed on the heater framework embeds in the draw-in groove of heater framework), and the gear shaft 2-3(conventional structure that vertically is arranged in these fixed plate top and bottom respectively), passing spool 2-2(gear shaft, passing spool and fixed plate can be one-body molded), described gear shaft and passing spool coaxial arrangement and all make the tubular structure that is beneficial to wiring and (be proof strength, gear shaft also can be made solid shaft), one gear 2-1 is fixedly arranged on the gear shaft, and the gear in two articulated joints is meshing with each other to guarantee stability of rotation.Owing to the rotation angle between two heater frameworks is limited, therefore described gear can be the gear along the whole circumferential arrangement of gear shaft, also can be the gear along half circumference of gear shaft, specifically determines as required.
Described hinged cover is spliced by fore shell 3-1, back cover 3-2, and fore shell and back cover are fastenedly connected (in fore shell and the back cover, one of them is shaped on screw, and another is shaped on the through hole that screw passes through) mutually by two screws.Fore shell and back cover respectively are shaped on two half-cylindrical concave surface 3-3 that vertically stretch, the half-cylindrical concave surface of fore shell and the half-cylindrical concave surface of back cover are in opposite directions and to arranging, the splicing back forms two hinging holes of vertically arranging, gear shaft, the passing spool of an articulated joint is installed respectively in each hinging hole.The semi-cylindrical recesses that is shaped on the along continuous straight runs stretching, extension on described fore shell and the back cover respectively (also can be other shape, as long as can be communicated with described hinging hole), the two ends of the semi-cylindrical recesses of substantially horizontal are connecting the half-cylindrical concave surface (structure of back cover is similar) of two vertical directions stretching, extensions of fore shell respectively on the fore shell, the semi-cylindrical recesses of two levels is in opposite directions and to arranging, splicing back forms a cable-through hole and is beneficial to wiring, power line 5 by this cable-through hole from a passing spool through another passing spool.
As shown in Figure 7, in the described hinge structure, the angle of the central point line L1 of two gear shafts and the symmetrical center line L2 of one of them heater framework is α, the angle of the central point line of two gear shafts and the symmetrical center line L3 of another heater framework is β, the numerical value of angle α equates all the time with angle β in rotation process, thereby guarantees the stability of rotation.
In fact, because described passing spool and the vertical coaxial arrangement of gear shaft, both effects and a hinging shaft are similar, can be so that heater framework flexible, smooth rotation centered by the hinging hole of hinged cover influence installation work simultaneously, and monnolithic case is attractive in appearance.
Also has the containment vessel 4 of protection power line among the figure.
