The specific embodiment
Be to reach technological means and the effect that predetermined utility model purpose is taked for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, to the specific embodiment of the present utility model, structure, feature and effect thereof, be described in detail as follows.
Figure 1 shows that the assembling schematic diagram of LGP fixation kit of the present utility model and a liquid crystal module.Fig. 2 is the enlarged diagram of Fig. 1 centre circle II.As shown in Figures 1 and 2, LGP fixation kit of the present utility model comprises some fixtures 10.In the present embodiment, the quantity of fixture 10 is 4, and it is located at respectively four corners of LGP 20.Understandable, the quantity of fixture 10 is not limited to this, and it can be adjusted according to shape and the design requirement of LGP 20.
Figure 3 shows that the schematic perspective view of fixture 10 among Fig. 1.As shown in Figure 3, described fixture 10 comprises the first holder 12 and the second holder 14 that is embedded in the first holder 12.
The first holder 12 is made the first supporting rod 123 and the second supporting rod 125 that it comprises base 121 and is located at 121 two adjacent edges of base by non-elastic materials such as Merlon (PC), ABS resins.The certain distance in interval between the opposite end of the first supporting rod 123 and the second supporting rod 125, and the first supporting rod 123 is perpendicular to the second supporting rod 125.Particularly, the first supporting rod 123 is extended upward by a vertical edge of base 121 upper surface perpendicular to base 121, and the second supporting rod 125 is by a horizontal sides of base 121 extending upward perpendicular to the upper surface of base 121.
The second holder 14 has flexible material by silica gel, rubber etc. and makes.The second holder 14 comprises pedestal 141 and is located at the first elastic 143 and second elastic 145 of 141 two adjacent edges of pedestal.Pedestal 141 is embedded in the set rectangular recess in base 121 corners.The opposite end of the first elastic 143 and the second elastic 145 links together, and the first elastic 143 is perpendicular to the second elastic 145.Particularly, the first elastic 143 is extended upward by a vertical edge of pedestal 141 upper surface perpendicular to pedestal 141, and links to each other with the first supporting rod 123 of the first holder 12.The second elastic 145 is extended upward by a horizontal sides of pedestal 141 upper surface perpendicular to pedestal 141, and links to each other with the second supporting rod 125 of the first holder 12.The first supporting rod 123, the second supporting rod 125, the first elastic 143, the second elastic 145 all have one day to the surface of LGP 20, and the surface towards LGP 20 of the first elastic 143 and the second elastic 145 protrudes from respectively the surface towards LGP 20 of the first supporting rod 123 and second supporting rod 125 of the first holder 12.The outstanding distance of the first elastic 143 and the second elastic 145 needs to design according to the expansion distance of LGP 20 at correspondence direction.
As shown in Figure 1, when LGP fixation kit of the present utility model and liquid crystal module fitted together, fixture 10 was positioned at four corners of LGP 20.Particularly, when LGP fixation kit and liquid crystal module fit together, the first elastic 143 and second elastic 145 of the second holder 14 contact with LGP 20, the certain distance in interval between the first supporting rod 123 of the first holder 12 and the second supporting rod 125 and the LGP 20.After LGP 20 is heated, the moisture absorption expands, it is large that the size of LGP 20 becomes, the first elastic 143 and the second elastic 145 are subjected to the extruding of LGP 20 and are out of shape, when the size of LGP 20 expand into to a certain degree, the first supporting rod 123 will contact with LGP 20 with the second supporting rod 125 and utilize its rigidity restriction LGP 20 to continue the extruding injury of expanding LED being caused, thereby effectively protect LED.
In the utility model, the LGP fixation kit has been realized two kinds of effects, the one: the assembling original state positions LGP 20, prevents in transportation, the handling process damage and failure to LGP 20 and LED, guarantees optical effect; The 2nd: spacing to LGP 20 in LGP 20 expansion processes, avoided the harmful effect that LGP 20 expands LED is produced in varying environment (comprising high temperature, high humidity environment), guarantee reliability, security in its use procedure.
Need to prove, in the present embodiment, the first holder 12 is made by non-elastic material, the second holder 14 is made by elastomeric material, be appreciated that ground, the first holder 12 and the second holder 14 all can be made by elastomeric material, only need to guarantee that first holder 12 have certain rigidity, and the elasticity of the second holder 14 gets final product greater than the elasticity of the first holder 12.
In the present embodiment, the second holder 14 comprises respectively the first elastic 143 and the second elastic 145 that links to each other with the second supporting rod 125 with the first supporting rod 123, understandable, the second holder 14 also can include only the first elastic 143 and the second elastic 145 one of them, when the second holder 14 includes only an elastic, this elastic specifically be located at which direction need to according to when design needs distortion buffering direction determine.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet be not to limit the utility model, any those skilled in the art, within not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solutions of the utility model content, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
