Fig. 3 is the structural representation of the another kind of heating bar of the utility model;
Wherein: 10, cylindrical shell; 20, heat conduction support; 21, container cavity; 22, inserting groove; 23, defining flange; 30, shell fragment; 31, plug-in mounting end; 40, heater; 50, spring.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
As Fig. 1, shown in 2, for the heating bar of a kind of curler of the present utility model, it comprises the cylindrical shell 10 of the hollow of being made up of aluminium or steel, two heat conduction supports 20, heater 40 and two shell fragments 30, wherein, heat conduction support 20 can adopt heat conductivility better, the metal material that intensity is higher is made, two heat conduction supports 20 are all arranged in the inner chamber of cylindrical shell 10, it is axial consistent with cylindrical shell 10 axially, the inner surface laminating of the outer surface of heat conduction support 20 and cylindrical shell 10, the two can carry out heat transmission smoothly to make it, concrete is, the inner chamber axial cross section of cylindrical shell 10 is circular, its outer surface that the cross section of heat conduction support 20 intercepts be shaped as a circular arc line, the circular equal diameters that the diameter of this circular arc line becomes with cylindrical shell 10 inner chamber axial cross sections, it is the whole inner surface that is fitted in cylindrical shell 10 of outer surface of heat conduction support 20, thereby increase contact area, improve the efficiency of hot transmission.On heat conduction support 20, offer one along its container cavity 21 that axially (being the axial of cylindrical shell 10) extends, two above-mentioned heaters 40 lay respectively in the container cavity 21 of two heat conduction supports 20.
Two shell fragments 30 are arranged on respectively between the same side of two heat conduction supports 20, its the two for two heat conduction supports 20 are pushed up to pressure laterally, make two heat conduction supports 20 there is the trend of moving towards away from each other, make heat conduction support 20 can with good the contacting of the inner surface of cylindrical shell 10, to eliminate the gap between heat conduction support 20 and cylindrical shell 10 inner surfaces, concrete is, the both sides of shell fragment 30 are respectively arranged with a plug-in mounting end 31, the both sides of heat conduction support 20 are respectively arranged with an inserting groove 22, two plug-in mounting ends 31 of shell fragment 30 both sides are inserted into respectively in the inserting groove 22 of two heat conduction support 20 the same sides, so, two shell fragments 30 apply elastic stress to the side of two heat conduction supports 20 respectively, make the gapless laminating of inner surface of outer surface and the cylindrical shell 10 of heat conduction support 20.In addition, in order to guarantee that heating bar normally works, be also provided with a defining flange 23 in the outside of inserting groove 22, this defining flange 23 departs from from inserting groove 22 for preventing plug-in mounting end 31.
In such scheme, owing to adopting two shell fragments 30 to be arranged between two heat conduction supports 20, heat conduction support 20 is applied to outside thrust, make the inner surface of heat conduction support 20 outer surfaces and cylindrical shell 10 seamless applying, improved the heat transference efficiency between heater 40 and cylindrical shell 10.
