It is plugged together with double card groove bayonet, and double-legged positioning pin can be rotated 360 ° around its handle axis to tense rope.
LED Light-Bar basal plate heated occurs local micro-strain and causes to be not fixed firmly or rigidly consolidate in order to prevent
Determine mode damaged substrate, it is preferred to use high temperature resistant elastic rope, rope still has elasticity under the high temperature conditions.
The quantity of single deck tape-recorder groove bayonet is unlimited in above-mentioned one group of rope positioning group, is preferably provided with two single deck tape-recorder groove bayonets.
Light-Bar location and installation can be arranged convex on backboard using limit hole is arranged on Light-Bar on backboard
Packet, limit hole and convex closure correspond, and are used to Light-Bar location and installation on backboard；It can also use and be set on backboard
Light-Bar limiting slot is set, the location and installation for Light-Bar.
Rope positioning group quantity on one piece of backboard is unlimited, can be determined, i.e., can be set on backboard according to backboard size
Set multiple groups rope positioning group.
The utility model has the advantages that compared with prior art, direct-light type LED backlight Light-Bar fixed form tool disclosed by the invention
It has the advantage that 1, LED Light-Bar is fixed by rope, single foot positioning pin and double-legged positioning pin, it is simple to operation；2, subtract
Few LED Light-Bar fixed operation manpower and working hour；3, elastic rope is fixed, after LED Light-Bar basal plate heated by
It is flexible in rope, it can prevent from being not fixed firmly or rigidly fix mode caused by the micro-strain of substrate part and damage base
Plate.
