Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes.Obviously, described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, the every other implementation that those skilled in the art are obtained under the premise of creative work is not made
Example, belongs to the scope of protection of the invention.
Refering to Fig. 1 to Fig. 5, in an embodiment of LED display of the present invention, LED display is including LED box 10 and extremely
Few one group of support component 20.
LED box 10 includes display surface 101 and the back side 102 relative with display surface 101.The display surface 101 is provided with LED
Lamp, shown for realizing, at least one is provided with along the direction of top 103 to bottom 104 of LED box 10 on the back side 102
The direction that first guide rail 11, the i.e. length direction of the first guide rail 11 point to bottom 104 with the top 103 of LED box 10 is consistent.Its
In, the first sliding block 12 that can be slided along the first guide rail 11 is installed on first guide rail 11.
Support component 20 includes base 21 and telescopic support bar 22, and support bar 22 for example can be fluid pressure type support
Bar.Base 21 is a strip support, and one end of base 21 is arranged on the bottom 104 of LED box 10, and is located at LED box
10 back side 102.One end of support bar 22 is rotatably connected by the first rotary shaft 221 with base 21, the other end of support bar 22
It is rotatably connected by the second rotary shaft 222 with the first sliding block 12.
Wherein, as shown in figure 3, being provided with two relative projections 211 on the other end of the base 21 away from LED box 10,
Through hole is offered on two projections 211, through hole is also equipped with one end of support bar 22 and is inserted between two projections 211,
The through hole that first rotary shaft 221 is inserted on two projections 211 and support bar 22, so that support bar 22 and base 21 are rotatable
Connection.It is understood that two projections 211 are fixed on base 21, can be integrally formed with base 21, therefore support bar 22
Position on base 21 is changeless.In addition, as shown in Fig. 2 that relative two are also equipped with the first sliding block 12 is convex
Block 121, through hole is offered on two projections 121, through hole is also equipped with the other end of support bar 22 and is plugged and two projections
Between 121, so as to the through hole on the other end of the second rotary shaft 222 two projections 121 of insertion and support bar 22, so that branch
Strut 22 is rotatably connected with the first sliding block 12.
Wherein, the first sliding block 12 is fixed by the first fixture 122 and the phase of the first guide rail 11.First fixture 122 is for example
It can be bolt, screwed hole can be opened up on the first sliding block 12, then bolt is torqued into screwed hole, when bolt is tightened
The first sliding block 12 can be caused to be fixed on the first guide rail 11 without arbitrarily sliding.Alternatively, in order to improve the first sliding block 12
Fastness, multiple fixing holes 111, slip of multiple fixing holes 111 along the first sliding block 12 can be set on the first guide rail 11
Direction is arranged in order, the first fixture 122 optionally can coordinate with one of fixing hole 111 with by the first sliding block 12 and
The phase of first guide rail 11 is fixed, and specifically, the first fixture 122 penetrates the screwed hole and the first guide rail 11 of the first sliding block 12 successively
On fixing hole 111, tightening the first fixture 122 can mutually fix the first sliding block 12 with the first guide rail 11, side simple to operate
Just.
The LED display of the present embodiment, base 21, support bar 22 and LED box 10 form triangular shape, so as to utilize base
21 and support bar 22 can support LED box 10.Wherein, support can be driven when the first sliding block 12 slides along the first guide rail 11
Bar 22 is flexible, and support bar 22 elongates or shortens the angle of inclination that will change between LED box 10 and ground, and the first sliding block 12 is got over
Up the inclined degree of slip LED box 10 is bigger, i.e., the angle of inclination between ground is smaller, so as to realize LED display
Angle of inclination regulation.Wherein, when the first sliding block 12 slides into desired position, can be incited somebody to action by the first fixture 122
First sliding block 12 is fixed, and avoids the first sliding block 12 from gliding.
In addition, in order to be more convenient the angle of inclination of adjustment LED box 10, angle can be set on each side of fixing hole 111
Scale knows 112, to show when the first sliding block 12 slides into the position of some fixing hole 111 between LED box 10 and ground
Angle of inclination, angle mark 112 are, for example, specific angle, and such as corresponding angle identifies multiple fixing holes 111 from the bottom up
112 are followed successively by 90 °, 85 °, 80 °, 75 °, 70 °, wait by that analogy.
With continued reference to Fig. 1, in the embodiment of the present invention, the quantity of the first guide rail 11 and support component 20 is two.Wherein exist
In a kind of possible embodiment, two guide rails 11 are separately positioned on the side frame of left and right two 105,106 of LED box 10,
One support component 20 is corresponding to be engaged with first guide rail 11 to support LED box 10, the i.e. left and right two in LED box 10
Side is provided with support component 20 to support LED box 10 jointly.
Further, LED display also includes power control box 30.Power control box 30 is used to provide power supply, with driving
LED box 10 is shown.Power control box 30 is fixed on the back side 102 of LED box 10 by the second fixture 31.For example, the
