On a end face.
The idler wheel is rotated synchronously with elastic-friction wheel, described there are installation gap between elastic-friction wheel and idler wheel
Install and an annular electric heating sheets be equipped in gap, the electric heating sheets be clamped in an axial direction idler wheel and elastic-friction wheel it
Between, the conducting wire being connect with electric heating sheets is equipped in the shaft.
After more than structure, the guide roller of backlight kludge of the utility model a kind of have compared with prior art with
Lower advantage：First, shaft is for diaphragm when can reduce the diaphragm that shaft attaches on backlight module by elastic-friction wheel
Impact force, therefore be not easy to leave impression on diaphragm, secondly, by electric heating sheets can elastic-friction wheel be heated after along diameter
It resets, is achieved in for the adjustable of elastic-friction wheel outer diameter after expansion or cooling.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
The utility model provides a kind of guide roller of backlight kludge, it includes shaft 1, in the shaft 1 in an axial direction according to
Sequence is equipped with multiple idler wheels 2, it is characterised in that：An elastic-friction wheel 3, elastic-friction wheel 3 are equipped between two idler wheels 2 of arbitrary neighborhood
Central through hole is equipped with, the elastic-friction wheel 3 is sheathed on by central through hole outside shaft 1, and elastic-friction wheel 3 and shaft 1
Between be circumferentially rotatably assorted, the outer diameter of the elastic-friction wheel 3 is more than the outer diameter of idler wheel 2, when 3 lateral wall of elastic-friction wheel
Stress area bullet when partly or entirely by radial compression power on 3 lateral wall of elastic-friction wheel
The vertical range for being located at arbitrary point position to 1 axis of shaft in stress area on the lateral wall of frottage wheel 3 is less than or equal to
The 1/2 of 2 outer diameter of idler wheel.
The elastic-friction wheel 3 is the loop configuration of rubber material.
The elastic-friction wheel 3 includes the ring skeleton 3.1 of hard, and the outer diameter of ring skeleton 3.1 is less than the outer of idler wheel 2
Diameter, ring skeleton 3.1 are equipped with central through hole, and the ring skeleton 3.1 is rotatably assorted by central through hole and shaft 1, described
The elastic layer 3.2 of an annular is circumferentially coated on the lateral wall of ring skeleton 3.1, the outer diameter of elastic layer 3.2 is more than idler wheel 2
Outer diameter.
The elastic layer 3.2 extends radially to annular close to the position of 3.1 end face of ring skeleton along ring skeleton 3.1
