Embodiment
The erecting device of a kind of LED display of the utility model embodiment, its structure is as shown in Figure 1, comprising: bearing 1, mounting bracket 2 and pedestal 3.Wherein, said pedestal 3 is used for being fixedly connected with wall 6 supporters such as grade; The erecting device of the said LED display of one cover has three bearings 1; One end of said mounting bracket 2 is used for being rotatably connected through the screen body 5 of a said bearing 1 with LED display, and the other end is used for being rotatably connected with said pedestal 3 through two said bearings 1.Certainly, if the intensity of supporter is enough, pedestal 3 also can omit, and two bearings 1 of mounting bracket 2 one ends directly are fixedly connected through modes such as swell fixtures with supporter, also can reach essentially identical technique effect.
The concrete structure of said bearing 1 is as shown in Figure 2, comprising: bearing substrate 10 and bearing cantilever 12.Said bearing substrate 10 is used for wall 6 supporters such as grade or shields body 5 being fixedly connected; Thereby in this embodiment; Bearing substrate 10 is provided with two screw holes 101, is used for being connected through modes such as swell fixtures with wall 6, perhaps is used for being connected through bolt or screw with screen body 5.
In the optimized technical scheme, the both sides of the edge vertical extent of said bearing substrate 10 forms strengthens side plate 11, and the reinforcement side plate 11 of bearing substrate 10 and its both sides forms the structure of similar channel-section steel, can improve the bulk strength of bearing 1.Said bearing cantilever 12 and said bearing substrate 10 vertical settings are used for being rotatably connected with said mounting bracket 2, thereby are provided with pin shaft hole 121 on it.
As shown in Figure 2, because pivot hole 121 places are stressed bigger, and pivot hole 121 places can be because relatively rotate and rubbed, so in the optimized technical scheme, pivot hole 121 places are provided with thickening circle 122, and the part is strengthened.
Like Fig. 2 and shown in Figure 1, in the optimized technical scheme, a side of said bearing cantilever 12 also is provided with stiffening plate 13, and said stiffening plate 13 is " U " shape, and this kind mode makes the bulk strength of bearing 1 higher.
As shown in Figure 3, mounting bracket 2 adopts the square tube steel to be welded basically.Because triangular structure is the most stable, mechanical property is best, the mounting bracket 2 in this embodiment, and its main body is triangular in shape, and it has triangular structure in other words.It has triangular structure of right angle in particular in this embodiment; This triangular structure of right angle comprises: hypotenuse pole 22, long right angle side pole 23 and short right angle side pole 24; Thereby also having had three tie points, three tie points are corresponding respectively with three angles of right-angled triangle.
Wherein, an end of said long right angle side pole 23 is provided with pivot pin 21, and said pivot pin 21 is used for cooperating with the pivot hole 121 of bearing 1, makes mounting bracket 2 and bearing 1 be rotatably connected.
The other end of long right angle side pole 23 then is provided with pin shaft hole 26, and is as shown in Figure 4, and said pin shaft hole 26 is used for being rotatably connected through bearing pin 4 and another bearing 1.
Need to prove that an end and the bearing 1 of long for ease right angle side pole 23 are rotatably connected, and do not influence motion between the two, short right angle side pole 24 is not connected with long right angle side pole 23 ends, but has stayed certain distance.In like manner, pivot pin 21 is set for ease and does not influence pivot pin 21 performance functions, hypotenuse pole 22 is not connected with the other end end of long right angle side pole 23 yet.For an end of hypotenuse pole 22 can be rotatably connected through bearing 1 and wall 6, also be provided with extension rod 25.One end of extension rod 25 is fixedly connected (the general mode of welding that adopts is fixedly connected) with the end of hypotenuse pole 22 and short right angle side pole 24, the other end then is provided with pin shaft hole 27, and said pin shaft hole 27 is used for being rotatably connected through bearing pin 4 and bearing 1; And extension rod 25 laterally arranges with long right angle side pole 23.
Said pedestal 3 is as shown in Figure 5, is the channel steel shape structure, has body 30, and offers a plurality of long strips hole 301 on the body 30, is used for being fixedly connected with wall 6 supporters such as grade.
When LED display screen body 5 is installed, according to the situation of screen body 5 dorsal parts, four bearings 1 are passed through the dorsal part of screw at screen body 5 earlier.As shown in Figure 6 then, two pedestals 3 are fixed on the body of wall 6 through swell fixture, and keep between distance and the screen body 5 dorsal part bearings 1 between two pedestals 3 about distance equate.Then four mounting brackets 2 are respectively passed through two bearings 1, be mounted to respectively on two pedestals 3, and the perpendicular distance between the pivot pin 21 equates with the perpendicular distance of shielding between the body 5 dorsal part bearings 1 on the maintenance mounting bracket 2.To shield the bearing 1 of body 5 through its dorsal part then and hang on the corresponding pivot pin 21 and get final product, install afterwards as shown in Figure 7.
Like Fig. 8 and shown in Figure 9, screen body 5 is actually through two groups of parallel-crank mechanisms and is connected with body of wall 6, and Fig. 8 is its normality, and Fig. 9 to be it open the state when safeguarding.The erecting device 1 of a kind of LED display of employing the utility model technological scheme is installed the screen body 5 of LED display; Not only easy for installation; And need safeguard the time, only need just can be opened into state as shown in Figure 9 screen body 5 gently toward extrapolating; With the sizable distance of body of wall 6 distances, thereby maintenance, repair are very much convenient.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
