Description

Technical Field

[0001] The present invention relates to the technical field of LED display screens, and particularly to a display screen installation structure based on an LED display panel. Background Art

[0002] An LED display screen is an active controllable electroluminescent device with LEDs as the basic light-emitting elements. Through the system's control processing unit, it can display information such as text, graphics, and images. The LED display screen adopts low-voltage scanning drive and has the advantages of low power consumption, low cost, high brightness, large viewing angle, long visible distance, waterproof, and a variety of specifications and varieties, which can meet the requirements of various different application scenarios. It has a very broad development prospect and is recognized as the most growth-potential and fastest-growing LED application market.

[0003] Existing indoor and outdoor large LED display screens, such as the Chinese utility model patent with the patent number ZL201420685738.1 discloses an LED display screen box body and an LED display screen, and its LED display screen includes an LED display screen box body and a display module installed on the LED display screen box body. Another example is the Chinese utility model patent with the patent number ZL201921475480.1, which discloses a display screen box body, an LED display screen, and an LED display screen assembly structure, and its LED display screen includes an LED module, a power supply box, and a display screen box body.

[0004] As described above, since existing LED display screens are all assembled from multiple display units, and the display units need to use the box body as a carrier, in order to meet the requirements of the box body for structural strength, its heavy and thick disadvantage is inevitable. Therefore, existing LED display screens have the following defects: 1. Because they are heavy and thick, they are inconvenient during transportation, handling, installation, and maintenance; 2. The smallest assembly unit is the box body, and the size of the entire display screen can only be adjusted according to the number of box bodies. Since each box body contains several modules, the size adjustment of the display screen is not flexible enough; and the size of the box body is generally unified in the industry and is difficult to change; 3. The cost is higher, whether it is the production cost, transportation cost, or installation and maintenance cost, all increase due to its heavy and thick characteristics; 4. The appearance is bulky and the aesthetics is poor.

[0005] Therefore, in order to solve the above defects, an LED display panel is envisioned, and the entire display screen is directly formed by assembling the LED display panels. For this purpose, a set of installation structure to replace the box body is needed to ensure the surface flatness and structural stability of the display screen. Summary of the Invention

[0031] The present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0032] The LED display panel mentioned in the present invention is a thin plate structure provided with a display component, and the present invention mainly introduces the installation structure for assembling multiple LED display panels or similar plate structures into an entire LED display screen.

[0033] Such as Figure 1 As shown, a display screen installation structure based on an LED display panel includes a longitudinal assembly component for realizing the longitudinal assembly of multiple LED display panels 1, a horizontal assembly component for realizing the horizontal assembly of the LED display panel 1, and an installation component for realizing the installation and fixation of the entire display screen. Since the LED display panel 1 is generally designed as a cuboid structure with a wide horizontal and narrow vertical shape, the number of LED display panels assembled longitudinally is relatively large. Therefore, the overall assembly concept of the present invention is to first assemble multiple longitudinally arranged LED display panels to form an LED display panel group, and then horizontally assemble two or more groups of LED display panels to simplify the assembly structure and improve the assembly efficiency. In addition, through a clever design, the present invention combines the above-mentioned horizontal assembly component and installation component into a splicing and installation component, that is, a set of components is used to simultaneously realize the horizontal splicing of two groups of LED display panels and the installation and fixation of the entire display screen to the square steel.

[0034] Such as Figure 2As shown in the figure, the longitudinal assembly component includes a longitudinal reference member 21, and locks and positioning posts 23 provided on the LED display panel 1. Among them, the longitudinal reference member 21 is an integrally formed profile with high structural strength and flatness. Multiple LED display panels 1 are successively and closely installed on the plane of the longitudinal reference member 21, ensuring the flatness of the surface of the longitudinally assembled LED display panels. Moreover, the longitudinal reference member 21 is arranged at the back of the LED display panel 1 near the left and right sides, that is, a group of LED display panels are longitudinally assembled by two longitudinal reference members 21 on the left and right. At the same time, it is arranged on the left and right sides of the LED display panel 1, so that it is not only used for the longitudinal assembly component, but also for the splicing and installation component, to reduce the number of parts, simplify the installation process, and reduce costs at the same time.

[0035] As Figure 3 shown in the figure, the longitudinal reference member 21 specifically includes a splicing portion 211 and a connecting portion 212. The splicing portion 211 is mainly a flat plate horizontally attached to the back of the LED display panel 1, and is used to closely hold the square steel. The square steel is also a reference member, that is, the installation stability and the flatness of the display screen surface are ensured through the cooperation of two reference surfaces. If the side end of the LED display panel has an inclined surface structure with a wider front and a narrower rear, then only the front part of the laterally adjacent LED display panels abuts against each other. Therefore, a part of the splicing portion 211 needs to extend outside the LED display panel. That is, through the mutual abutment of the splicing portions 211 of two adjacent longitudinal reference members 21, the abutment effect on the back side between the laterally adjacent LED display panels is realized, so as to ensure that there is abutment between the laterally assembled LED display panels both in the front and in the back, that is, to ensure the flatness after assembly. Moreover, in order to make the abutment relationship between the splicing portions 211 of two longitudinal reference members 21 more stable, the end of the splicing portion 211 has a section of abutment strip 2111 that is vertically bent inward, which is used to increase the abutment area. At the same time, the inclined surface structure at the side end of the LED display panel 1 also provides space for the abutment strip 2111 to prevent the abutment strip 2111 from bending outward, thus ensuring the flatness of the side of the splicing portion 211 facing away from the LED display panel, so as to facilitate the installation and fixation in cooperation with the square steel 5.

[0036] The connecting portion 212 mainly includes a locking groove 2121 and a tensioning groove 2122 which are arranged back to back and both penetrate up and down. The two share a groove bottom plate 2123, and both have a limiting structure with a narrow opening and a wide inner cavity. Among them, the locking groove 2121 faces the LED display panel 1 and is used to cooperate with the lock and the positioning post 23 to realize the installation connection between the LED display panel and the longitudinal reference member 21. Specifically, a positioning post 23 and two locks are provided at the left and right ends of the back of each LED display panel. The positioning post 23 is located in the middle, and the two locks are respectively arranged on both sides of the positioning post 23. Correspondingly, positioning holes for cooperating with the positioning post 23 are provided on the groove bottom plate 2123, and the distance between adjacent positioning holes is equal to the longitudinal width of the LED display panel 1 to ensure the installation accuracy and improve the installation efficiency at the same time.

[0037] As Figure 4 shown, the lock includes a lock core 221, a lock core sleeve 222, a fixing block 223, and a thrust screw 224. Holes are provided on both the front and back sides of the plate body of the LED display panel. The lock core 221 is inserted through the hole on the back side until the end just inserts into the hole on the front side. Lock blocks 2211 are provided on both opposite ends of one end of the lock core 221, and the distance between the opposite ends of the two lock blocks 2211 is greater than the width of the opening of the locking groove 2121, that is, when the lock core 221 rotates until the two lock blocks 2211 are in the width direction of the locking groove 2121, the two lock blocks 2211 are limited in the locking groove 2121; when rotated until the two lock blocks 2211 are in the length direction of the locking groove 2121, the lock blocks 2211 and the lock core 221 can be withdrawn from the locking groove.

[0038] An annular locking platform 2212 is provided on the middle side surface of the lock core 221. On the locking platform 2212, a locking inclined surface 2213 is provided on one side facing the lock block 2211. There are two identical locking inclined surfaces 2213. The lower part of one locking inclined surface is connected to the upper part of the other locking inclined surface, and limiting platforms 2214 are provided at both connection points. Correspondingly, two push screws 224 are fastened to the back side through a fixing block 223 on the inner side surface of the LED display panel. The two push screws 224 are respectively located on the opposite sides of the lock core 221. At the same time, part of the screw heads of the two push screws 224 needs to protrude beyond the edge of the opening on the back side to cooperate with the locking inclined surface 2213. Of course, the fixing block 223 also has a through hole for the lock core 221 to pass through. When the lock core rotates, due to the pushing action between the locking inclined surface 2213 and the push screw 224, the lock core 221 will gradually move forward to the front side of the LED display panel, so that the two lock blocks 2211 gradually press the part of the opening of the lock groove 2121, realizing the locking connection between the LED display panel 1 and the longitudinal reference member 21. And, on the side surfaces of the two limiting platforms 2214, in-place prompt protrusions 2215 are provided, and in-place prompt grooves 2232 are provided on the inner side wall of the through hole of the fixing block 223. On the one hand, it is used to position the locking position of the lock core to avoid loosening; on the other hand, when the operator cannot see the inside of the lock, by sensing the vibration or sound when the in-place prompt protrusion 2215 is caught in the in-place prompt groove 2232, the operator can master the situation of the lock core rotating in place.

[0039] A lock core sleeve 222 is sleeved on the part of the lock core 221 inside the LED display panel 1, that is, the lock core sleeve 222 is located between the end of the locking platform 2212 facing away from the locking inclined surface 2213 and the front side surface of the plate body to limit the distance that the lock core 221 moves forward to the front side of the LED display panel 1. Finally, internal hexagonal holes are provided at both the front and rear ends of the lock core 221 for front maintenance and rear maintenance respectively. Correspondingly, holes for the hexagonal wrench to extend into need to be opened on the display surface of the LED display panel and on the groove bottom plate 2123.

[0040] Such as Figure 2As shown, the splicing and installation component includes a horizontal reference member 31, a stud 32, a tension block 33, a tension nut 34, and a positioning nut 35. Generally, this display screen can be installed on the vertically fixed square steel 5 to utilize the properties of high structural strength and good surface flatness of the square steel structure as the reference member. It mainly realizes the installation and fixation of the display screen by the splicing part 211 of the horizontal reference member 31 and the two longitudinal reference members 21, which tightly hold the two opposite side surfaces of the square steel 5. Moreover, due to the high surface flatness of the side surface of the square steel 5, when the splicing parts 211 of the two longitudinal reference members 21 are simultaneously in close contact with the side surface of the square steel 5, it ensures that the two splicing parts 211 are in the same plane, that is, the adjacent two groups of LED display panels are in the same plane, which also guarantees the flatness of the surface of the horizontally assembled LED display panels. Among them, the horizontal reference member 31 can be made of a steel plate with higher strength and a straight surface, and it will not deform under the action of the holding pressure between it and the square steel 5; while the splicing part 211 of the longitudinal reference member 21 has a part that directly adheres to the back side of the LED display panel 1, so the holding pressure between the square steel 5 and it will be transferred to the LED display panel, and thus the splicing part 211 will not be deformed either.

[0041] It should also be noted that the horizontal reference member 31 and the two longitudinal reference members 21 only hold the front and back side surfaces of the square steel 5, and the distance between the connecting parts 212 of the two longitudinal reference members 21 is greater than the left-right width of the square steel 5 to leave an adjustment space. Because when there are three or more groups of horizontally assembled LED display panels, the number of square steels required is two or more, and there will be a certain error in the distance between the square steels during installation. If the above adjustment space is not left, the display screen will not be successfully installed in the case of an error in the distance between the square steels. At the same time, the levelness of the display screen is guaranteed by the horizontal ground or the lower horizontal support structure, that is, the above adjustment space will not cause the display screen to tilt.

[0042] Specifically, the tensioning block 33 can be fixed to one end of the stud 32 in advance by means of drilling a threaded hole or the like. The tensioning block 33 slides in from the side opening of the tensioning groove 2122. At the same time, the stud 32 connected to the tensioning block 33 slides along the notch of the tensioning groove 2122 until the required installation position is reached. Then, the positioning nut 35 is screwed onto the stud 32 until it is fastened to the notch of the tensioning groove 2122 to fix the position of the tensioning block 33. And the tensioning block 33 has a width adapted to the tensioning groove 2122, that is, it will not rotate on its own within the tensioning groove 2122, and the positioning nut 35 can be screwed tightly smoothly. Of course, in order to improve the fastening stability, a gasket is provided between the positioning nut 35 and the longitudinal reference member 21. When the studs 32 are installed and fixed on both of the butted longitudinal reference members 21 and abutted against the square steel 5, the transverse reference member 31 is sleeved onto the two studs 32 simultaneously through the holes opened therein. Finally, the tensioning nut 34 is screwed onto the stud 32 until it is fastened to the surface of the transverse reference member 31. Similarly, a gasket is also provided between the tensioning nut 34 and the transverse reference member 31. And since the force at the tensioning groove 2122 is greater than that at the locking groove 2121, in order to ensure the structural strength at the tensioning groove 2122, both sides of the notch of the tensioning groove 2122 have a section of structure that is vertically bent inward to increase the thickness of the tensioning groove 2122 in the force direction. And the tensioning nut 34 can specifically adopt a wing nut to facilitate the installation and maintenance personnel to tighten it directly by hand. Of course, the number of splicing and installation components used needs to be adjusted according to the height of the display screen to ensure the installation stability.

[0043] Thus, all the LED display panels 1 are locked and integrated with the longitudinal reference members 21, and the longitudinal reference members 21 and the transverse reference members 31 are clamped to the square steel 5, so that all the LED display panels 1 are supported by the square steel 5 with reliable strength, and the stability of the entire display screen is guaranteed.

[0044] It should be noted that since the tensioning block 33 can slide freely along the tensioning groove 2122, as long as there is no interference with other components, the entire splicing and installation assembly can freely select the installation position on the longitudinal reference member 21 according to the actual situation, thereby improving the installation flexibility and applicability.

[0045] It should also be noted that since the locking groove 2121 and the tensioning groove 2122 are arranged in opposite directions, the force of the tensioning block 33 on the tensioning groove 2122 and the force of the locking block 2211 on the locking groove 2121 act in opposite directions on the same straight line, so that the force on the longitudinal reference member 21 is more balanced and the deformation of the longitudinal reference member is avoided.

[0046] In addition, after the box body is removed, the power control box needs to be installed outside the LED display panel, and the tensioning groove 2122 of the longitudinal reference member 21 also provides an installation position for the power control box. That is, both ends of the power control box 4 are respectively installed and connected to the longitudinal reference members 21 at both ends of the LED display panel 1. This also enables the power control box 4 not to be directly in close contact with the LED display panel 1, and there is a heat dissipation gap between the two to prevent the LED display panel 1 from being affected by the heat generated by the power control box 4. Among them, as Figure 5 and 6 shown, both ends of the power control box 4 are provided with integrally formed mounting parts. The mounting parts include a connecting plate 41 fixed to the side end of the power control box 4 by screws, two fastening plates 42 respectively arranged on both sides of the connecting plate 41, and a hand-held plate 43 arranged at the upper end of the connecting plate 41. The fastening plates 42 are formed by cutting longitudinal grooves on the connecting plate 41 and then bending them by 90°. The hand-held plate 43 is formed by directly bending the upper part of the connecting plate 41 by 90°. A hole is opened on the fastening plate 42, and a fastening nut 44 is arranged in the tensioning groove 2122 of the longitudinal reference member 21. The fastening bolt 45 passes through the hole on the fastening plate 42 and is threadedly connected and fastened to the fastening nut 44, thereby realizing the installation and fixation of the power control box 4.

[0047] Moreover, since a plug-in panel for connecting the power control box 4 needs to be provided on the back of the LED display panel, if the power control box 4 slides along the back of the LED display panel to the installation position, it will interfere with the plug-in panel. Therefore, it can only be directly attached at the correct position, that is, the fastening nut 44 cannot be connected to the fastening bolt 45 in advance, but the fastening nut 44 needs to be separately moved into place in the tensioning groove 2122 and then connected to the fastening bolt 45 passing through the fastening plate 42. For this reason, it is necessary to ensure the position stability of the fastening nut 44 after it is moved into place in the tensioning groove 2122. Therefore, a spring piece 441 is arranged on its side. The spring piece 441 bends towards the bottom of the tensioning groove, and a clamping groove 442 is also arranged on the groove bottom plate 2123 for clamping the end of the spring piece 441, so that the spring piece 441 always remains in a taut state to always press the fastening nut 44 against the notch of the tensioning groove 2122 to prevent it from sliding randomly along the tensioning groove. Of course, we can adjust the position of the fastening nut 44 manually according to the actual situation to adjust the installation position of the power control box 4 on the longitudinal reference member 21, so as to ensure the flexibility and applicability of the installation. And, in order to prevent the fastening nut 44 from rotating when the fastening bolt 45 rotates, a boss 443 is arranged on the fastening nut 44 to be clamped into the notch of the tensioning groove 2122 to realize the limit of the fastening nut 44. At the same time, the above spring piece structure also ensures that the boss 443 of the fastening nut 44 is always clamped into the notch of the tensioning groove. In addition, the hand-held plate 43 is mainly used to provide a force application position for the installation and maintenance personnel when moving the power control box.

[0048] In summary, the installation principle of this installation structure is as follows:

[0049] First, longitudinally assemble multiple LED display panels. First, place multiple LED display panels face down, align and lay them on a horizontal plane in sequence, and ensure that the locking blocks 2211 on the lock cores 221 of each LED display panel face the longitudinal splicing direction. Then align the positioning holes on the longitudinal reference member 21 with the positioning posts 23 on the back of the LED display panel to closely attach the longitudinal reference member 21 to the back of the LED display panel. Then use an Allen wrench to pass through the hole on the inner groove bottom plate 2123 of the longitudinal reference member and insert it into the Allen hole at the end of the lock core 221, and rotate the lock core so that the locking block 2211 of the lock core presses the longitudinal reference member 21 against the LED display panel. Complete the locking work of all locks in sequence, and install longitudinal reference members 21 at both ends of the LED display panel. Finally, install the power control box 4 on the back of a group of LED display panels, and plug the cables on each plug-in panel into the power control box. Thus, the assembly of a group of LED display panels is completed. Usually, the above assembly process also needs to be completed before leaving the factory to avoid being affected by the environment at the display installation site, and at the same time minimize the installation procedures at the installation site and improve the installation efficiency at the site.

[0050] Secondly, at the display installation site, horizontally assemble multiple groups of LED display panels and install them on the square steel 5 of the display installation bracket at the same time, and proceed in the installation order from bottom to top. First, slide the required number of tension blocks 33 together with the studs 32 into the tension slots 2122 on the longitudinal reference member 21 at the horizontal splicing position until the installation position, and then screw the positioning nuts 35 onto the studs 32 to fix the positions of the tension blocks 33 and the studs 32. When all the required studs are installed and fixed, lift the two groups of LED display panels to be assembled and make their longitudinal reference members simultaneously abut against the front side of the square steel 5. Then slip the horizontal reference member 31 onto the left and right studs 32 and tighten the tension nuts 34 on the studs 32. Install the horizontal reference member 31 on each group of studs in sequence, and the horizontal assembly of the two groups of LED display panels is completed until all groups of LED display panels are installed on the square steel 5, thus completing the installation of the entire display.
