It is vertically installed in spring, support bar lower end is fixedly connected with base.
Used as preferred technical scheme, buffer unit is fixedly installed on the bottom surface of light guide plate mounting groove by equal base,
A plastic hoop part in buffer unit is inserted in corresponding deep-slotted chip breaker respectively, and the outer ring face that plastic hoop is located in deep-slotted chip breaker is equal
Internal face with deep-slotted chip breaker offsets.
Used as preferred technical scheme, LED modules are fixedly installed in the lower end of light guide plate mounting groove, and LED modules are by one
LED above and PLC circuit plate composition, the irradiation end of LED is towards the lower surface of light guide plate.
Used as preferred technical scheme, support bar and base are made by metal material.
The beneficial effects of the utility model are：The utility model simple structure, it is easy to use, by being arranged in deep-slotted chip breaker
Buffer unit can the damage that is caused to light guide plate of effective damping vibration, increased the service life of light guide plate, and by leading
The plastic layer of tabula rasa both sides can effectively avoid light guide plate side light leak, and increased light guide plate goes out bright intensity.
Brief description of the drawings
In order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is buffer unit structure schematic diagram of the present utility model.
Specific embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine by any way.
This specification（Including any accessory claim, summary and accompanying drawing）Disclosed in any feature, except non-specifically is chatted
State, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature
It is an example in a series of equivalent or similar characteristics.
As depicted in figs. 1 and 2, a kind of backlight module of LCDs of the present utility model, including light guide plate 3, installation
Plate 13 and LED modules, the upper end of the installing plate 13 are provided with a light guide plate mounting groove 1, and light guide plate 3 is arranged at the light guide plate mounting groove
In 1, a plastic layer 2 is fixedly mounted on the left and right sides of light guide plate 3, more than one deep-slotted chip breaker 6 is equipped with plastic layer 2, led
Tabula rasa mounting groove 1 is located at the deep-slotted chip breaker 6 on plastic layer 2 and is equipped with a buffer unit 4, and buffer unit 4 is by plastic hoop 14, spring
9th, base 12 and support bar 11 are constituted；
Spring 9 is fixedly installed in the inner ring of plastic hoop 14, and the lower end of spring 9 is fixedly connected with described base 12,
Support bar 11 is vertically installed in spring 9, and the lower end of support bar 11 is fixedly connected with base 12.
Buffer unit 4 is fixedly installed on the bottom surface of light guide plate mounting groove 1 by equal base 12, the modeling in buffer unit 4
The material part of ring 14 is inserted in corresponding deep-slotted chip breaker 6 respectively, and plastic hoop 14 is located at outer ring face in deep-slotted chip breaker 6 and deep-slotted chip breaker
6 internal face offsets.
Wherein, LED modules are fixedly installed in the lower end of light guide plate mounting groove 1, and LED modules are by the He of more than one LED 7
