Description
Technical field
The present invention relates to a kind of positioning devices for light guide plate.
Background technique
With the continuous development of technology, consumer is higher to the requirement for surveying light LED liquid crystal television, and " ultra-narrow " (frame is super
It is narrow), " ultra-thin " (thickness ultrathin) become the new development trend of straight-down negative LED liquid crystal television.Light guide plate is electric as light LED liquid crystal is surveyed
Depending on the core optical component in machine, the specific gravity accounted in television set complete machine is increasing.As shown in Figure 1, being led in conventional television
Tabula rasa is positioned by left and right positioning column 1 and upper and lower positioning column 2, wherein positioning column 2 can be symmetrical when light guide plate is heated up and down
Ground expands up and down, and left and right positioning column 1 can the symmetrically left and right expansion when light guide plate is heated.But it is this by positioning up and down
The structure of column can not control the expansion of light guide plate to having any different property, be easy that light guide plate is made to weigh LED wounded in expansion process
The elements such as lamp cause unnecessary loss, shorten the service life of television set, increase the operation and maintenance cost of consumer；Separately
Outside, positioning column is pressurized in light guide plate expanded by heating, but cannot spring back or spring back in time that the time is long, is unfavorable for consumer's
It uses.
Summary of the invention
Present invention seek to address that the above problem, provides a kind of positioning device for light guide plate, positioning device is effective
The expansion direction for guiding light guide plate is LED light source to be protected well, so that the brightness of LED light is more steady far from LED light bar direction
Risk fixed, that LED is subject to crushing caused by reducing because of light guide plate expansion；When light guide plate is shunk, block is in recoil of spring, first
Frame and second support intersecting angle reduce and by block top under the action of light guide plate, set back, and block return is reused,
Reduce the cost of maintenance block and more shift block, effect is obvious；Entire positioning device structure is simple, practical；It is used
Technical solution it is as follows:
A kind of positioning device for light guide plate, including block, first support, second support and spring, the block are set
It is placed on backboard, and is located at light guide plate side；The first support and second support intersect in X-type, and first support and the
Two brackets are hinged in intersection；One end in the same direction of the first support and second support is movably connected on block, and
Block two sides are symmetrically distributed in light guide plate；The other end of the first support is bent to form the first fixed part, and described first is solid
Determine portion and is plugged in the first positioning hole being arranged on backboard；The second support is identical as the structure of first support, second support
Second fixed part is plugged in the second location hole on backboard, is formed with boss at the first positioning hole and second location hole,
The spring one end is fixed in first support, and the other end is fixed in second support, and spring and block are distributed in first
The two sides of frame and second support hinge joint.
Based on the above technical solution, the block is silicagel pad.
Based on the above technical solution, the first positioning hole and second location hole in the same plane, and with
The hinge joint of first support and second support is that midpoint is symmetrical.
Based on the above technical solution, the first support and second support are elastic support.
The invention has the benefit that first support and second support are located at bullet when block is expanded by light guide plate and squeezed
The intersecting angle of spring side expands, spring elongation, block it is mobile to the boss at location hole until spring reach limit of stretch or
When block is stopped by boss, block stops movement, and light guide plate continues to expand to the orientation of not obstacle at this time, such case
Under, it is separate LED light bar direction that positioning device, which effectively guides the expansion direction of light guide plate, LED light source is protected well, so that
The brightness of LED light is more stable, the risk that LED is subject to crushing caused by reducing because of light guide plate expansion；When light guide plate is shunk, block
Reduced in recoil of spring, first support and second support intersecting angle and by block top to light guide plate under the action of, set back,
Block return is reused, and the cost of maintenance block and more shift block is reduced, and effect is obvious；Entire positioning device structure letter
It is single, it is practical.
Detailed description of the invention
Fig. 1: the structural schematic diagram of existing way in background technique；
Fig. 2: structural schematic diagram of the invention.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples:
As shown in Fig. 2, a kind of positioning device for light guide plate of the present embodiment, including block 1, first support 2, second
Bracket 3 and spring 4, the block 1 are set on backboard 100, and are located at 200 side of light guide plate；The first support 2 and second
Bracket 3 intersects in X-type, and first support 2 and second support 3 are hinged in intersection；The first support 2 and second support
3 one end in the same direction is movably connected on block 1, and is symmetrically distributed in 1 two sides of block with light guide plate 200；Described first
The other end of frame 2 is bent to form the first fixed part 21, and first fixed part 21 is plugged in the first positioning being arranged on backboard 100
Hole；The second support 3 is identical as the structure of first support 2, and the second fixed part 31 of second support 3 is plugged on backboard 100
Second location hole in, boss 101 is each formed at the first positioning hole and second location hole, described 4 one end of spring is affixed
In in first support 2, the other end is fixed in second support 3, and spring 4 and block 1 are distributed in first support 2 and second support
The two sides of 3 hinge joints.
Preferably, it in order to not damage light guide plate in use, while preferably setting back, the block 1 is silicon
Rubber mat.
Preferably, the first positioning hole and second location hole in the same plane, and with first support 2 and second
The hinge joint of frame 3 is that midpoint is symmetrical.
Further, in order to be not easily broken when being pressurized while convenient for rebound, mitigate maintenance cost, 2 He of first support
Second support 3 is elastic support.
Certain positions of light guide plate are arranged in positioning device according to actual needs, when block is expanded by light guide plate and is squeezed,
The intersecting angle that first support and second support are located at spring side expands, and spring elongation, block is moved to the boss at location hole
It moves until block stops movement, and light guide plate is at this time to no obstacle when spring arrival limit of stretch or block are stopped by boss
Orientation continue to expand, in this case, the effective expansion direction for guiding light guide plate is far from LED light bar direction, well
LED light source is protected, so that the brightness of LED light is more stable, the risk that LED is subject to crushing caused by reducing because of light guide plate expansion；?
When light guide plate is shunk, block is reduced in recoil of spring, first support and second support intersecting angle and by block top to light guide plate
Under the action of, it sets back, block return is reused, and the cost of maintenance block and more shift block is reduced, and effect is obvious.
The present invention is described by way of example above, but the present invention is not limited to above-mentioned specific embodiment, all to be based on
Any changes or modifications that the present invention is done are fallen within the scope of the claimed invention.
