Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Please refer to Fig. 1 and Fig. 2, the better embodiment of fixer for heat radiator of the present invention can be used for fixing a heating radiator 60.This fixer for heat radiator comprises that one is installed in the second locking part 30, four springs 40 and the four c-shaped fixing sheets 50 that the first locking part 20, that backboard 10, three on a circuit board is arranged in this heating radiator 60 is arranged in this heating radiator 60.
This heating radiator 60 comprises a foursquare base plate 61 and is vertical at some radiating fins 63 on this base plate 61.The contiguous four pin places, top of this base plate 61 are provided with respectively a perforation (not shown).This four perforation is with respect to the Central Symmetry setting of this base plate 61.
This backboard 10 is square.The contiguous wherein three drift angle places of the end face of this backboard 10 upwards are convexly equipped with respectively one first fixed leg 12, and contiguous another drift angle place upwards is convexly equipped with one second fixed leg 14.This 3 first fixed leg 12 and the Central Symmetry setting of this second fixed leg 14 with respect to this backboard 10.The top of each the first fixed leg 12 is to having a threaded hole 121.This second fixed leg 14 comprises the projection 141 that is connected in this backboard 10 and has an externally threaded double-screw bolt 143 by the top of this projection 141 is upwardly extending.This backboard 10 is installed on circuit board with a default angle take this second fixed leg 14 as mark.
Each first locking part 20 comprises a head 21, has externally threaded double-screw bolt 25 to a cylinder 23 of downward-extension and by the middle part of the bottom of this cylinder 23 to one of downward-extension by the middle part of the bottom surface of this head 21.Contiguous double-screw bolt 25 places, the bottom of this cylinder 23 are provided with a ring groove 231.Each first locking part 20 passes a perforation of subscribing of the base plate 61 of a spring 40 and this heating radiator 60.Three fixing sheets 50 are placed in respectively the ring groove 231 of these 3 first locking parts 20 by the below of the base plate 61 of this heating radiator 60, thereby this 3 first locking part 20 are arranged in three perforation of being scheduled to of this heating radiator 60.The head 21 of the first corresponding locking part 20 and the end face of the base plate 61 of this heating radiator 60 are supported respectively in the two ends of each spring 40.
This second locking part 30 comprises a head 31 and by the middle part of the bottom surface of this head 31 cylinder 33 to downward-extension.The middle part of the bottom surface of this cylinder 33 upwards is provided with a threaded hole 331.The bottom adjacent floor of this cylinder 33 is provided with a ring groove 333.This second locking part 30 passes another perforation of the base plate 61 of a spring 40 and this heating radiator 60.Fix sheet 50 with one and be placed in the ring groove 333 of this second locking part 30 by the below of the base plate 61 of this heating radiator 60, thereby this second locking part 30 is arranged in the predetermined perforations of this heating radiator 60.The head 31 of this second locking part 30 and the end face of the base plate 61 of this heating radiator 60 are supported respectively in the two ends of this spring 40.
