Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of shadowless lamp LED backlight as shown in Figs 1-4, including shadowless lamp shell 1, described
Several first attachment bases 2, the middle part of first attachment base 2 are symmetrically fixedly installed in the left and right sidewall of shadowless lamp shell 1
It is rotatably equipped with strut 4 by the first connecting shaft 3, the end of the strut 4 is set to the inside of spring supporting set 5, the bullet
The inside of spring support sleeve 5 is provided with compressed spring 14, and the upper end of the compressed spring 14 is fixedly connected with metal plate 15, the bullet
Spring support sleeve 5 is rotatablely installed in the second attachment base 9 by two second connecting shafts 17 being symmetrically fixedly mounted on lateral wall
Portion, the second attachment base 9 are fixedly installed in the side wall of 10 shell of LED backlight, the ipsilateral spring branch of 10 shell of LED backlight
Kelly 7 is fixedly installed between support set 5, the kelly 7 is clamped with deck 6, and the deck 6 is fixedly installed in shadowless lamp shell 1
Bottom, the bottom and side wall of 10 case inside of LED backlight is respectively arranged with LED light emitting diode 13 and light guide plate
11。
Specifically, the strut 4 is slidably connected by rod set 8 and spring supporting set 5, the rod set 8 is fixedly installed in bullet
The end of spring support sleeve 5, and one end that strut 4 is contacted with metal plate 15 is socketed with frosted rubber sleeve 16, guarantees that strut 4 can edge
The radial direction of spring supporting set 5 slide, thus vertically extruding metal plate 15, thus compressed spring 14, by the end of strut 4
It is arranged to the inside of spring supporting set 5, and provides frictional force by frosted rubber sleeve 16, strut 4 and metal plate 15 is avoided to send out
Raw opposite sliding.
Specifically, the deck 6 is the unit of plastic that top offers card slot 12, it is equipped on the inner sidewall of the card slot 12
Silica gel pad 18, the cushion effect provided by silica gel pad 18 guarantee the stability that kelly 7 is clamped in card slot 12, thus fixed
The firmly position of spring supporting set 5 guarantees the stability that 10 shell of LED backlight is installed inside shadowless lamp shell 1.
Specifically, the light guide plate 11 is acryl plates, and the 10 equal adhesion of shell front and rear inner side walls of LED backlight is led
Tabula rasa 11 reflects light source by the high reflectivity of light guide plate 11 and the not characteristic of extinction, guarantee, guarantees LED backlight
The intensity for the light source that source 10 discharges.
Specifically, first attachment base 2 is welded in the top of 1 lateral wall of shadowless lamp shell, the strut 4 passes through end
Two first connecting shafts 3 rotational installation being symmetrically fixedly installed with guarantees that strut 4 turns to the in the middle part of the first attachment base 2
