Thus, the number of the installation components 300 can be reasonably reduced on the basis of ensuring the stable and reliable installation of the display screen 500.
For example, each display unit 520 includes three display cases 510, and the display cases 510 have a length of 0.5 m and a height of 1.5 m. The display unit 520 is fixedly connected with two mounting bars 400, and the same mounting bar 400 is connected between two adjacent display boxes 510, i.e. the same mounting bar 400 is arranged at the butt joint of the two adjacent display boxes 510. For a display 500 having a length of 174 meters and a height of 29.5 meters, the weight of the mounting mechanism 200 is about 14 tons when the design mode is adopted, i.e., the weight of the mounting mechanism 200 for each flat meter display 500 is about 2.7 kg. For example, corresponding to the second mounting notch 421a and the second mounting hole 421b on the same second mounting portion 421, the fastener in the second mounting notch 421a fixes the display case 510 located below to the mounting bar 400, and the fastener in the second mounting hole 421b fixes the display case 510 located above to the mounting bar 400, thereby achieving fixing of two adjacent display cases 510 on the same display unit 520 to the same mounting bar 400. When the length of the mounting bar 400 is 3 meters, since the total length of the spliced six display units 520 is 3 meters, six display units 520 can be fixed on the same mounting bar 400, and therefore two mounting bars 400 with the length of 3 meters can fix six display units 520.
When each display unit 520 includes three display cases 510, the display unit 520 has a length of 3 meters and a height of 0.5 meter. The number of the mounting bars 400 is two in view of the fact that the mounting bars 400 are disposed at the butt joint of the adjacent two display cases 510, and two at the butt joint formed by the respective adjacent display cases 510. When each display unit 520 includes four display cases 510, there are three junctions formed by respective adjacent display cases 510, so the number of the mounting bars 400 may be three. However, for the butt joint of two adjacent display units 520, the butt joint is not provided with the mounting bars 400, so that on one hand, the number of the mounting bars 400 can be reduced, and the weight of the whole mounting mechanism 200 is reduced, and then the weight borne by the support frame 100 is reduced, namely, the load of the support frame 100 is reduced, the phenomena that the support frame 100 is inclined, rocked or damaged under the action of a larger load are avoided, and the mounting stability and the safety of the support frame 100 are improved. On the other hand, the material cost of the entire mounting mechanism 200 can be reduced while also suitably reducing the number of assembly and disassembly of the mounting bar 400, thereby improving the assembly and disassembly speed of the mounting mechanism 200. The assembly process of the display unit 520 is also reduced, thereby improving the assembly and disassembly speed of the display screen 500.
If the mounting mechanism 200 adopts a structure including both weft and warp, on the one hand, the weight of the mounting mechanism 200 increases, i.e., the weight of the mounting mechanism 200 corresponding to each square meter of the display screen 500 is about 15 kg or more, and for a display screen 500 having a length of 174 meters and a height of 29.5 meters, the weight of the mounting mechanism 200 may be 77 tons or more. This increases the consumption of steel by the mounting mechanism 200, and ultimately increases the material cost of the mounting mechanism 200. On the other hand, given the need to hoist the mounting mechanism 200 from the ground to a certain height to reach the support frame 100, a heavy weight mounting mechanism 200 would significantly increase the cost and difficulty of hoisting. Meanwhile, the installation mechanism 200 with larger weight can generate larger bearing capacity for the support frame 100, so that the load born by the support frame 100 is increased, and the support frame 100 is inclined, rocked or damaged under the action of the larger load, thereby affecting the stability and safety of the installation of the support frame 100. Particularly in the case of high winds, there is a risk of this support 100 collapsing completely. On the other hand, the thickness of the mounting mechanism 200 is larger, so that the display screen 500 protrudes by a larger length, which is about 0.5 meters, from the support frame 100 along the thickness direction of the display screen 500, and the protruding length can be understood as the distance between the display screen 500 and the support frame 100, and in view of the larger protruding length, the gravity of the display screen 500 generates a larger overturning moment on the support frame 100, which also affects the stability and reliability of the installation of the whole support frame 100. Meanwhile, a more obvious layering sense exists between the display screen 500 and the supporting frame 100, so that the overall consistency of the display device 10 is affected.
Whereas for the mounting mechanism 200 in the above embodiment, the mounting mechanism 200 includes only the mounting assembly 300 that is relatively independent and acts as a weft, thereby eliminating the presence of warp threads. Thus, the weight of the mounting mechanism 200 can be reduced, the steel consumption of the mounting mechanism 200 can be increased, and the material cost of the mounting mechanism 200 can be reduced. Secondly, the lifting difficulty and the lifting cost of the mounting mechanism 200 can be reduced, the load of the support frame 100 is reduced, and the stability and the safety of the mounting of the support frame 100 are improved. Thirdly, the width dimension of the first mounting plate 410 is smaller, and meanwhile, the first mounting notch 411a is arranged on the first mounting plate 410, so that the distance between the display screen 500 and the support frame 100 can be reduced, the protruding length of the display screen 500 relative to the support frame 100 is reduced, the gravity of the display screen 500 generates smaller overturning moment on the support frame 100, and the stability and reliability of the installation of the support frame 100 are improved. And also eliminates layering caused by the large protruding length, so that the display screen 500 and the support 100 have a visual impression of being integrated.
For the installation of the whole display device 10, the supporting frame 100 and the installation mechanism 200 can be synchronously performed, and in view of each installation bar 400 having a set length, the construction error of the supporting frame 100 can be adjusted by the set length of the installation bar 400, for example, the space between the two supporting rods 110 is reasonably adjusted to reduce the installation error, so that the length of the supporting frame 100 is prevented from being smaller than the length of the display screen 500, and the situation that the display screen 500 cannot be completely installed is avoided. The length of the supporting frame 100 can be prevented from being longer than that of the display screen 500, and the phenomenon that the display effect is affected due to overlarge gaps between two adjacent display units 520 can be avoided. After the support frame 100 and the mounting mechanism 200 are assembled, the display unit 520 may be hoisted to a position corresponding to the mounting bar 400 by a small winch, thereby fixing the display unit 520 on the mounting bar 400, and finally, the entire display screen 500 is mounted. Of course, a certain gap may be reserved between two adjacent display units 520, so as to offset the installation error of the support 100. When the entire display device 10 needs to be removed, the display screen 500 must first be removed. In view of the fixed set number of display units 520 on each mounting bar 400, the disassembling personnel can disassemble the display units 520 on each mounting bar 400 simultaneously in multiple ways, thereby improving the disassembling efficiency of the display screen 500.
