Description

Technical Field

[0001] This utility model relates to a wall-mounting bracket mechanism for displays, and more particularly to a wall mounting mechanism and its wall panel assembly for splicing multiple electronic displays together horizontally to achieve a large-screen display. Background Technology

[0002] Television or computer monitors are typically wall-mounted in places like restaurants and shopping malls to provide viewers with dynamically changing information. In recent years, with the widespread use of large-screen LCD displays in public areas such as restaurants, shopping malls, and airports, there has been a pressing need for wall-mounted devices that can connect multiple displays together and fix them to walls.

[0003] The wall panel assembly includes a wall-mounting mechanism fixed to the wall, a mounting rod connected to the wall-mounting mechanism, and multiple brackets for connecting multiple monitors. Each bracket is mounted on the mounting rod, allowing multiple monitors to be mounted on a single rod to achieve a large-screen effect. The brackets can tilt relative to the mounting rod, allowing the monitors to adjust their tilt relative to the wall for better viewing.

[0004] However, the wall mounting mechanisms currently on the market only serve to fix the wall to the wall and support the mounting rod. This results in a complex horizontal adjustment function structure and installation process for the wall panel components. Furthermore, the front and rear adjustment structures are prone to angle changes when adjusting the tilt, making it difficult to adjust to the required angle. Utility Model Content

[0005] Therefore, it is necessary to provide a wall mounting mechanism and its wall panel assembly that can install two or more electronic displays on a wall in the horizontal direction and can adjust the height, front and back, and tilt angle of the electronic displays within a certain range.

[0006] One embodiment of this utility model provides a wall panel assembly for fixing a mounting bracket for an electronic display to a wall, characterized in that it comprises:

[0007] The wall panel section secures the entire wall panel assembly to the wall;

[0008] A height adjustment unit is movably mounted on the wall panel and is capable of moving up and down along the length of the wall panel.

[0009] The front-to-back adjustment part is movably installed on the side of the height adjustment part away from the wall panel part, and can move back and forth along the width direction of the wall panel part.

[0010] This utility model also provides a wall mounting mechanism having the above-mentioned wall panel assembly, which is used to mount multiple electronic displays on a wall. The wall mounting mechanism is characterized in that it includes:

[0011] At least two wall panel assemblies are used for fixed installation on the wall;

[0012] At least one guide bar, which is engaged within at least two of the said wall panel assemblies; and

[0013] Multiple mounting brackets, detachably mounted on the side of at least one of the guide bars away from the wall panel assembly, are used for connection and fixation to the multiple electronic displays.

[0014] The mounting bracket is secured to one side of the guide strip, and the wall panel assembly is attached to the side of the guide strip opposite to the mounting bracket.

[0015] The wall panel assembly includes:

[0016] The wall panel section secures the entire wall panel assembly to the wall;

[0017] A height adjustment unit is movably mounted on the wall panel and is capable of moving up and down along the length of the wall panel.

[0018] The front-to-back adjustment part is movably installed on the side of the height adjustment part away from the wall panel part, and can move back and forth along the width direction of the wall panel part.

[0019] Compared to existing technologies, the wall-mounting mechanism provided by this invention can horizontally connect and fix multiple displays to a wall, and can be adjusted horizontally and backward within a certain range. The height and backward adjustment functions of the wall-mounting mechanism are integrated into the wall panel assembly; the mounting bracket of the wall-mounting mechanism also has a tilt angle adjustment function. The height and backward adjustment structure of the wall panel assembly of the wall-mounting mechanism of this invention is less prone to displacement, and the manufacturing process is simple and cost-effective; in addition, the mounting bracket of the wall-mounting mechanism can prevent the tilt adjustment structure from easily changing during angle adjustment, making the tilt adjustment more precise.

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] Furthermore, the terms "first" and "second" are used only to distinguish components and should not be construed as indicating or implying relative importance or the number of technical features.

[0038] The specific embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0039] like Figure 1 As shown, a wall mounting mechanism 100 according to an embodiment of the present invention can mount multiple displays together to achieve a multi-screen splicing effect. The wall mounting mechanism 100 includes at least two wall panel assemblies 10, at least one elongated guide strip 20, and multiple mounting brackets 30. The wall panel assembly 10 is fixed to the wall surface, the guide strip 20 is detachably mounted on the side of the wall panel assembly 10 away from the wall surface, and the multiple mounting brackets 30 are detachably spaced on the guide strip 20.

[0040] The wall mounting mechanism 100 of this utility model can be applied to dual-screen, triple-screen, quad-screen, or five-screen displays. In the case of a dual-screen display, there are two wall panel assemblies 10 and four mounting brackets 30. That is, four mounting brackets 30 are engaged on one side of the guide bar 20, and two wall panel assemblies 10 are attached to the opposite side. In the case of a triple-screen display, there are two wall panel assemblies 10 and six mounting brackets 30. That is, six mounting brackets 30 are engaged on one side of the guide bar 20, and two wall panel assemblies 10 are attached to the opposite side. In the case of a quad-screen display, there are three wall panel assemblies 10 and eight mounting brackets 30. That is, eight mounting brackets 30 are engaged on one side of the guide bar 20, and three wall panel assemblies 10 are attached to the opposite side. Whether there are four, six, or eight mounting brackets 30, they are arranged in pairs, parallel to each other, with an appropriate distance between them. The wall panel assemblies 10 are also spaced appropriately apart.

[0041] Figure 2 yes Figure 1 An enlarged schematic diagram of part A of the wall-mounted mechanism 100 shown. (See diagram below.) Figure 2 As shown, gaps 22 for hanging the wall panel assembly 10 are formed between the back of the guide strip 20 and the upper and lower ends of the protrusion 201, respectively.

[0042] Please refer to the following: Figure 3In this embodiment, the case of splicing and installing four displays is used as an example. The total length of the wall mounting mechanism 100 suitable for four screens is approximately 3968mm. It can be adjusted vertically by 50mm and horizontally by 24.3mm by the wall panel assembly 10. The tilt angle can be adjusted from 0° to 20° by the mounting bracket 30, and it can be locked at 0° and 10° by the angle fixing screw, with a maximum limit angle of 20°. The cross-sectional dimensions of the guide strip 20 along the width direction are approximately 150mm × 20mm. The dimensions of the mounting bracket 30 are approximately 426mm long × 47mm wide, and the maximum spacing between the mounting holes on it is 400mm. A protrusion 201 is formed on the back side of the guide strip 20 (the side connected to the wall panel assembly 10) along its length direction. The length of the protrusion 201 is the same as the overall length of the guide strip 20, and the width of the protrusion 201 is approximately 90mm.

[0043] Please refer to the following: Figure 4 and Figure 5 In this embodiment, the three wall panel assemblies 10 are fixed to the wall and have height adjustment and front-back adjustment functions. Specifically, each wall panel assembly 10 includes a wall panel portion 11 that mates with the wall, a height adjustment portion 13, a front-back adjustment portion 15, and a mounting portion 17. The wall panel portion 11 is fixedly installed on the wall surface. The height adjustment portion 13 is movably installed on the wall panel portion 11 and can move up and down along the length of the wall panel portion 11 to adjust the height. The front-back adjustment portion 15 is movably installed on the side of the height adjustment portion 13 away from the wall panel portion 11 and can move back and forth along the width of the wall panel portion 11 to adjust the front-back distance from the wall surface. The mounting portion 17 is fixedly installed on the side of the front-back adjustment portion 15 away from the height adjustment portion 13 and is used to connect to the guide strip 20.

[0044] The wall panel 11 is U-shaped and includes a base plate 111 and two side plates 113 perpendicularly connected to the two long sides of the base plate 111. The base plate 111 and the two side plates 113 cooperate to form a receiving space 115 for accommodating the height adjustment part 13. Fixing holes 112 are formed at both the upper and lower ends of the base plate 111 for fixing the entire wall panel assembly 10 to the wall. Sliding grooves 117 are provided on the side plates 113. In this embodiment, the upper fixing hole 112 is gourd-shaped, and the lower fixing hole 112 is circular. With this design, after the entire wall panel assembly 10 is fixed to the wall, it will not move upwards due to external forces.

[0045] The height adjustment unit 13 is movably installed between the two side plates 113, and a portion thereof is housed within the receiving space 115. The height adjustment unit 13 includes a fixed plate 131, a height adjustment plate 133, and a height adjustment screw 135.

[0046] The fixing plate 131 is fixed to the wall panel 11 and is located at the upper end of the wall panel 11 in a manner perpendicular to the bottom plate 111 of the wall panel 11, for mounting the height adjustment screw 135.

[0047] The height adjustment plate 133 is U-shaped and includes a back plate 1331 and two side plates 1333 perpendicularly connected to the two long sides of the back plate 1331. The side plates 1333 are arranged opposite to the side plates 113 of the wall panel portion 11, that is, the side plates 1333 of the height adjustment plate 133 are located between the two side plates 113 of the wall panel portion 11. Each side plate 1333 has a slider 1334 at its upper and lower ends. Each slider 1334 extends outward from the edge of the side plate 1333 in a direction perpendicular to the side plate 1333. The slider 1334 is inserted into the slide groove 117 and can move up and down along the slide groove 117 to realize the height adjustment function of the wall panel assembly 10. The size of the back plate 1331 is slightly smaller than the size of the bottom plate 111 of the wall panel portion 11, so its two side plates 1333 can be accommodated in the receiving space 115 formed by the wall panel portion 11. In addition, the back plate 1331 has openings 1339 extending longitudinally through it near its four corners. Furthermore, a push plate 1335 protrudes from the upper part of the height adjustment plate 133 towards the bottom plate 111 of the wall panel 11, and the push plate 1335 has a threaded hole 1337 formed on it.

[0048] The height adjusting screw 135 passes sequentially through the fixed plate 131 and the height adjusting plate 133. The external thread on the height adjusting screw 135 engages with the internal thread on the push plate 1335 to allow the height adjusting plate 133 to move closer to or separate from the fixed plate 131. To prevent the height adjusting screw 135 from being pushed upward from the fixed plate 131, a locking nut 1351 is provided below the fixed plate 131 to engage with the rod portion of the height adjusting screw 135. The locking nut 1351 prevents the height adjusting screw 135 from shifting relative to the fixed plate 131 and being pushed out. When operating the height adjusting part 13, the height adjusting screw 135 is rotated. At this time, the height adjusting screw 135 rotates relative to the fixed plate 131, simultaneously causing the height adjusting plate 133 to move up and down. During this process, the four sliders 1334 on both sides of the height adjustment plate 133 slide up and down in the slide groove 117 respectively, and the entire height adjustment plate 133 moves longitudinally relative to the wall panel 11 (moving along the length direction of the wall panel 11), pushing the plate 1335 to move up and down along the periphery of the height adjustment screw 135.

[0049] The front-to-back adjustment section 15 is movably mounted on the side of the height adjustment plate 133 away from the wall panel portion 11 and can move along the width direction of the wall panel portion 11. The front-to-back adjustment section 15 includes a front-to-back adjustment plate 151, guide plates 153 protruding from approximately the four corners of the front-to-back adjustment plate 151 in a direction perpendicular to the front-to-back adjustment plate 151, an upper adjustment screw 155, and a lower adjustment screw 157. The four guide plates 153 of the front-to-back adjustment section 15 are movably inserted through the four openings 1339 of the height adjustment plate 133 and are movably connected to the height adjustment plate 133 via connectors 40. In this embodiment, the connectors 40 are preferably hollow rivets. The size of the front-to-back adjustment plate 151 is slightly smaller than the size of the back plate 1331 of the height adjustment plate 133, and it is assembled to the height adjustment plate 133 via the four guide plates 153. Specifically, each guide plate 153 has a guide groove 1531. The side plate 1333 of the height adjustment plate 133 is connected to the guide plate 153 via a connector 40. The side plate 1333 of the height adjustment plate 133 is sleeved on the outer rod of the connector 40 through a through hole, and the guide plate 153 is movably sleeved on the inner rod of the connector 40 through the guide groove 1531. The guide plate 153 can move back and forth relative to the connector 40 through the guide groove 1531. When the four guide plates 153 are pushed inward, the front and rear adjustment plate 151 moves back and forth relative to the rod of the connector 40. In addition, side plates 159 are connected to the left and right sides of the front and rear adjustment plate 151, and the side plates 159 cover the side plate 1333 of the height adjustment plate 133. Furthermore, the upper edge of the front and rear adjustment section 15 is provided with a peak-shaped protrusion 152, the top of which is recessed to form a roughly U-shaped limiting opening 1521. The upper adjustment screw 155 and the height adjustment screw 135 are perpendicular to each other and are spaced a certain distance apart. One end of the upper adjustment screw 155 is fixed to the height adjustment plate 133, and the other end passes through the height adjustment plate 133 and engages with the front and rear adjustment plate 151. Driven by the upper adjustment screw 155, the front and rear adjustment plate 151 moves toward the height adjustment plate 133, thereby allowing the front and rear adjustment plate 151 to move back and forth in the width direction of the wall panel section 11. The upper adjustment screw 155 includes a front and rear adjustment nut 1551 and a fixing screw 1553 that passes through the front and rear adjustment nut 1551. A limiting groove 1552 is formed on the front and rear adjusting nut 1551 along its circumference. A part of the front and rear adjusting nut 1551 is received in the limiting opening 1521, and the limiting groove 1552 is engaged in the side wall of the limiting opening 1521 to prevent the front and rear adjusting plate 151 from being displaced.One end of the fixing screw 1553 is vertically fixed to the back plate 1331 of the height adjustment plate 133 by welding, and protrudes from the back of the height adjustment plate 133 through the back plate 1331. The other end of the fixing screw 1553 is threadedly engaged with the front and rear adjusting nuts 1551. The front and rear adjusting nuts 1551 are threadedly engaged with the fixing screw 1553 welded to the height adjustment plate 133, and can rotate and move along the fixing screw 1553, thereby driving the front and rear adjusting plate 151 to move back and forth relative to the height adjustment plate 133. A threaded hole 1511 is formed in the middle of the lower part of the front and rear adjusting plate 151, and the lower adjusting screw 157 is installed on the front and rear adjusting plate 151 through the threaded hole 1511. The tail of the lower adjusting screw 157 can be moved to press against the height adjustment plate 133. When adjusting the front and rear position, the upper adjusting screw 155 and the lower adjusting screw 157 are adjusted simultaneously and in opposite directions. That is, the front and rear adjustment function of the wall panel assembly 10 is achieved by alternately rotating the front and rear adjusting nut 1551 and the lower adjusting screw 157, which drives the front and rear adjusting plate 151 to move back and forth.

[0050] The aforementioned hook portion 17 is further installed on the outer side of the front and rear adjustment plate 151. The hook portion 17 includes a generally square hook plate 171 and four connecting pieces 173 extending from the four corners of the hook plate 171 in a direction perpendicular to the hook plate 171. At the base of the two connecting pieces 173, a latching part 172 is provided, which latches onto the hanging arm 154 of the front and rear adjustment plate 151. The four connecting pieces 173 are respectively fixed to the side plate 159 of the front and rear adjustment plate 151 by fasteners such as screws. Two hook portions 175 are provided at the upper and lower ends of the hook plate 171 along the length of the wall panel portion 11. The two hook portions 175 are arranged vertically opposite each other and are formed by bending from the edge of the hook plate 171 in a direction away from the front and rear adjustment plate 151 and then protruding downwards. Two hooks 175 fold towards each other to hook into the gap 22 formed between the back of the guide strip 20 and the upper and lower ends of the protrusion 201, thereby fixing the wall panel assembly 10 to the back of the guide strip 20 (see...). Figure 2 ).

[0051] Please refer to Figure 6 for an explanation of the principles of the height adjustment and front-back adjustment functions of the wall panel assembly 10 of this utility model. Figure 6(a) is a schematic diagram showing the state of the height adjustment plate of the wall panel assembly 10 when it moves in the vertical direction. Figure 6(b) is a schematic diagram showing the state of the front-back adjustment plate of the wall panel assembly 10 when it moves in the front-back direction. As shown in Figure 6(a), during height adjustment, the height adjustment plate 133, the front-back adjustment part 15 inserted on the height adjustment plate 133, and the hooking part 17 fixed to the two side plates 1333 of the front-back adjustment part 15 move up and down as a whole relative to the bottom plate 111 of the wall panel part 11. During this process, the push plate 1335 of the height adjustment plate 133 can move up and down along the wall of the height adjustment screw 135 to a position near the end of the height adjustment screw 135, and the four sliders 1334 of the height adjustment plate 133 can move along the slide groove 117 to the lowest end of the slide groove 117 respectively; the height adjustment plate 133 is always housed in the concave receiving space formed by the wall plate portion 11, and the two side plates 159 of the front and rear adjustment plate 151 cover a part of the side plate 1333 of the height adjustment plate 133 and move up and down along the edge of the side plate 113 of the wall plate portion 11. As shown in Figure 6(b), when making front and rear adjustments, the front and rear adjustment nuts 1551 and the lower adjustment screw 157 are rotated alternately to drive the front and rear adjustment plate 151 to move back and forth. During this process, the fixing screw 1553 of the upper adjusting screw 155 remains stationary because it is welded to the back plate 1331; the front and rear adjusting nuts 1551 drive the front and rear adjusting plates 151 to move towards the height adjusting plate 133 until they contact the back plate 1331 of the height adjusting plate 133. During this process, the four guide plates 153 of the front and rear adjusting part 15 move back and forth within the opening 1339, and the guide grooves 1531 of each guide plate 153 slide back and forth on the rod of the connector 40; the hook part 17 fixed on the outside of the front and rear adjusting part 15 moves back and forth together with the front and rear adjusting part 15.

[0052] like Figure 7 As shown, Figure 7 The diagram illustrates the fitting relationship between the limiting groove 1552 of the front and rear adjusting nut 1551 and the limiting opening 1521 of the front and rear adjusting plate 151. From... Figure 7 It can be seen that if the front and rear adjusting nut 1551 is not provided with the limiting groove 1552, the front and rear adjusting plate 151 will not move back and forth with the front and rear adjusting nut 1551. That is, the setting of the limiting groove 1552 can prevent the front and rear adjusting structure of the wall panel assembly 10 from changing angle, making the front and rear adjustment more convenient and precise.

[0053] Figure 8 This is an exploded view showing the assembly method of the guide strip 20 of the wall mounting mechanism 100. Please refer to the diagram as well. Figure 1The guide strip 20 is made of aluminum profile, with one side connected to the mounting bracket 30 and the other side connected to the wall panel assembly 10 via the hook part 17. Typically, the guide strip 20 is composed of one or more aluminum profile sections. When composed of multiple sections, adjacent aluminum profiles are connected to each other by two connecting strips 21 inserted into grooves on their surfaces, and the connection points are reinforced by a first connecting plate 23 and a second connecting plate 25 located on the front and rear sides respectively. Specifically, the first connecting plate 23 has multiple screw holes 231 and multiple through holes 233, and the second connecting plate 25 has multiple through holes 251. The two connecting strips 21 have multiple fixing holes 211 corresponding to the positions of the first connecting plate 23 and the second connecting plate 25, allowing the first connecting plate 23 and the second connecting plate 25 to be fixed to opposite sides of the guide strip 20 using multiple short screws a and multiple long screws b.

[0054] Please refer to Figure 9, where (a) shows... Figure 8 The diagram shows a front view of the guide strips 20 assembled together. Figure 9(b) shows... Figure 8 The diagram shows the back of the guide strip 20 after assembly. In this embodiment, as shown in Figure 9(a), the first connecting plate 23 is a roughly rectangular plate with its center line along its short axis located at the joint of the two aluminum profiles. Three screw holes 231 are respectively opened on both sides of the center line in the vertical direction. Four through holes 233 arranged in a square are further opened on the outer side of each vertical row of screw holes 231. As shown in Figure 9(b), the second connecting plate 25 is a roughly square plate with three through holes 251 near its left and right sides. During installation, four short screws a are first passed through the four through holes 233 and secured in the fixing holes 211 on the connecting strip 21, thereby fixing the first connecting plate 23 to one side of the guide strip 20. Then, four long screws are passed through the through holes 251, the back of the guide strip 20, and the fixing holes 211 on the connecting strip 21 from the back of the guide strip 20, and finally screwed into the multiple screw holes 231 on the first connecting plate 23. Thus, the second connecting plate 25 is fixed to the back of the guide strip 20, and its position roughly corresponds to the middle part of the long axis of the first connecting plate 23 on the front of the guide strip 20. Of course, the shape of the first connecting plate 23 and the second connecting plate 25 is not limited to rectangle or square.

[0055] When assembling the wall panel assembly 10, firstly, the rod of the upper adjusting screw 155 is welded to the back plate of the height adjusting plate 133. Then, the limiting groove 1552 of the front and rear adjusting nuts 1551 is inserted into the limiting opening 1521 at the upper end of the front and rear adjusting plates 151. Next, the lower adjusting screw 157 is screwed into the back plate of the front and rear adjusting plates 151. Secondly, the four guide pieces 153 of the front and rear adjusting plates 151 are respectively inserted into the four openings 1339 of the height adjusting plate 133. Then, the four sliders 1334 on the left and right sides of the height adjusting plate 133 are pushed into the sliding grooves 117 along the edge of the wall panel part 11. Thirdly, the fixing plate 131 is fixed to the upper end of the wall panel part 11. Then, the height adjusting screw 135 is passed through the pushing piece 1335 of the fixing plate 131 and the height adjusting plate 133 in sequence, and the two are fastened together to complete the assembly of the wall panel assembly 10.

[0056] Please see Figure 10 , Figure 10 (a) is a three-dimensional view of the overall structure of the mounting bracket 30. Figure 10 (b) is a schematic diagram when the inclination of the connecting rod of the mounting bracket 30 relative to the main body of the hanging strip is 0 degrees. Figure 10 (c) is a schematic diagram when the inclination of the connecting rod of the mounting bracket 30 relative to the main body of the hanging strip is 10 degrees. Figure 10 (d) is a schematic diagram when the inclination of the connecting rod of the mounting bracket 30 relative to the main body of the hanging strip is 20 degrees.

[0057] like Figure 10 As shown in (a), the mounting bracket 30 includes a hanging strip body 31, a connecting rod 32 that is tiltable relative to the hanging strip body 31, a fixing frame 33 that is movably connected to the lower end of the connecting rod 32, an anti-theft lock plate 34 installed at the lower end of the fixing frame 33, a relatively thick mounting screw 35, a relatively thin angle fixing screw 36, and a padlock 37. The mounting bracket 30 can be angled between 0 and 20 degrees. At the 0-degree and 10-degree positions, the angle between the hanging strip body 31 and the fixing frame 33 can be fixed by the angle fixing screw 36, with 20 degrees being the maximum limit position.

[0058] The main body 31 of the hanging strip is groove-shaped for fixing the LCD display, and has a narrow, roughly rectangular base plate 311 and two side walls 313 perpendicularly connected to opposite sides of the base plate 311. The base plate 311 is used for fixed connection with the electronic display. A narrow, elongated moving groove 312 is provided on the upper part of each side wall 313. A first angle fixing hole 315 and a fourth angle fixing hole 314 are respectively provided on the outer side of the moving groove 312 and on the side wall 313 at the position corresponding to the connection between the connecting rod 32 and the fixing frame 33. A through hole (not shown) is also provided at the lower end of the side wall 313 corresponding to the anti-theft lock plate 34.

[0059] The connecting rod 32 is also groove-shaped, with a roughly elliptical opening on its base plate 321 and through holes (not shown) on its two opposite side plates 323. The upper end of the connecting rod 32 is fixed to the side wall 313 of the hanging strip body 31 by mounting screws 35. Specifically, the two ends of the mounting screws 35 pass through the through holes of the two side plates 323 of the connecting rod 32 and the moving grooves 312 on the side wall 313 of the hanging strip body 31, and the movement of the upper end of the connecting rod 32 relative to the hanging strip body 31 is achieved by friction members located on the inner side of the side wall 313 and nuts (not shown) on the outer side. A second angle fixing hole 324 (see figure) is further provided on the side plate 323 of the connecting rod 32 to cooperate with the fourth angle fixing hole 314. Figure 10 (d) The lower end of the connecting rod 32 is movably connected to the upper end of the fixed frame 33 via two connectors 40.

[0060] The fixing frame 33 is an irregularly shaped sheet with a perforated base plate 331 and two side walls 332 extending vertically from both sides of the base plate 331. The upper and lower ends of the two side walls 332 are respectively provided with flaps 333 and 334 (see reference). Figure 10 The upper wing 333 and the lower wing 334 of the fixing frame 33 form an engaging notch 335 between each side wall 332 (see...). Figure 10 (b) The guide bar 20 is housed within the engaging recess 335. In other words, the entire mounting bracket 30 is secured to the guide bar 20 via the engaging recess 335. The upper wing 333 of the fixing bracket 33 partially abuts against the two side plates 323 of the connecting rod 32, and is rotatably connected to each other via the connector 40. The left and right wing 333 at the upper end of the fixing bracket 33 are also provided with third angle fixing holes 336 (see reference) that cooperate with the first angle fixing hole 315. Figure 10(c) Additionally, the two upper left and right flaps 333 are irregularly shaped, with their lower ends forming a roughly V-shaped hook portion 3331 between them and the side wall 332. The hook portion 3331 is used to lock onto the back of the guide strip 20 to prevent the fixing bracket 33 from falling off. Furthermore, the lower flap 334 abuts against the inner surface of the side wall 313 of the hanging strip body 31, and is rotatably connected to the side wall 313 by two other connectors 40 of the same structure. The lower flap 334 is also provided with a connecting plate 337 that is vertically connected to it. A relatively long screw 338 passes through the connecting plate 337 and abuts against the back of the guide strip 20 to prevent the fixing bracket 33 from falling off the guide strip 20. The anti-theft lock plate 34 is also provided on one side of the lower flap 334. The anti-theft lock plate 34 is rotatably connected to the outer surface of the side wall 332 by another connector 40. Both the corner of the side wall 332 and the lower end of the anti-theft lock plate 34 have through holes (not shown) for the annular portion of the padlock 37 to pass through. The upper side of the anti-theft lock plate 34 is vertically engaged with the lower side of the guide strip 20 through a limiting opening. The padlock 37 can prevent criminals from removing the mounting bracket 30 from the guide strip 20 and thus stealing the LCD display.

[0061] Please see Figure 10 (b) ~ Figure 10 (d), such as Figure 10 As shown in (b), when the LCD is fixed on the mounting bracket 30, and the tilt angle of the LCD is 0 degrees, with both the connecting rod 32 and the fixing bracket 33 housed in the groove of the hanging strip body 31, one of the first angle fixing holes 315 and the third angle fixing hole 336 of the side wall 313 coincide. At this time, the position of the connecting rod 32 relative to the hanging strip body 31 can be maintained by inserting the aforementioned angle fixing screw 36 into the first angle fixing hole 315 and the third angle fixing hole 336. Figure 10 As shown in (c), when the LCD screen tilts downwards by 10 degrees, the connecting rod 32 and the fixing bracket 33 form a certain bending angle, which is approximately 140 degrees. The two ends of the mounting screw 35 move slightly downwards within the moving groove 312. At this time, the connecting rod 32 can be fixed at this angle relative to the hanging strip body 31 by passing the aforementioned angle fixing screw 36 through the fourth angle fixing hole 314 and the second angle fixing hole 324 located beside the moving groove 312. Figure 10 As shown in (d), when the LCD screen tilts downwards by 20 degrees, the bending angle between the connecting rod 32 and the fixing bracket 33 decreases to approximately 90 degrees. At this time, due to the downward pulling force of the electronic display, both ends of the mounting screw 35 move to the bottom of the moving slot 312 and can no longer move, and the connecting rod 32 and the fixing bracket 33 are maintained at this bending angle.

[0062] See below. Figure 1 and Figure 2 The operating steps for suspending multiple electronic displays onto a wall using the wall mounting mechanism 100 are described in detail. First, the mounting bracket 17 is removed from the wall panel assembly 10, and then the upper and lower ends of the base plate 111 of the wall panel assembly 10 are mounted to the wall by passing studs or the like through the fixing holes 112 on the wall panel portion 11. Next, one or two guide strips 20 of appropriate length are prepared according to the size and number of LCD screens. Then, the mounting brackets 17 of at least two wall panel assemblies 10 are respectively secured to the back of the aluminum profile of the guide strip 20, and the folded parts of the mounting brackets 17 are hooked into the gaps 22. Next, the mounting part 17 and the guide strip 20 are installed onto the wall panel assembly 10. Specifically, the latching part 172 of the mounting part 17 is first latched onto the hanging arm 154 of the front and rear adjustment plate 151. Then, the four connecting pieces 173 of the mounting part 17 are inserted into the inner sides of the side plates 159 on the left and right sides of the front and rear adjustment plate 151, and then fixed to the side plates 159 with screws. Next, multiple mounting brackets (also called hanging strip assemblies) 30 are installed onto the back of the electronic display, and then the electronic display with the mounting brackets 30 is installed onto the guide strip 20. Specifically, multiple mounting brackets 30 are fixed into the screw holes of the back cover of the electronic display using fasteners such as screws. Then, the engaging notches 335 of the fixing brackets 33 of the multiple mounting brackets 30 are respectively engaged and fixed to the front of the guide strip 20. Then, multiple screws 338 are respectively passed through the connecting plate 337 of the fixing bracket 33 and made to abut against the back of the guide strip 20. Finally, the annular part of the padlock 37 is passed through the through hole of the anti-theft lock plate 34 and the side wall 332 and locked into the lock hole, thus completing the hanging of the electronic display on the wall.

[0063] When using the wall mounting mechanism 100, to adjust the front-to-back distance of the wall panel assembly 10, alternately rotate the front-to-back adjusting nut 1551 and the lower adjusting screw 157 to move the front-to-back adjusting plate 151 back and forth. To adjust the vertical height of the wall panel assembly 10, rotate the height adjusting screw 135 to move the height adjusting plate 133 up and down, causing the sliders 1334 on both sides of the height adjusting plate 133 to move downward within the grooves 117 of the wall panel portion 11. Additionally, the mounting bracket 30 can be angled between 0 and 20 degrees. To adjust the tilt angle of the electronic display, pull the hanging strip body 31 of the mounting bracket 30, causing the mounting screw 35 at its upper end to slide downward within the moving groove 312 of the side wall 313 of the hanging strip body 31 to the specified position, thereby tilting the hanging strip body 31 relative to the fixing frame 33 to the required angle. The mounting bracket 30 can fix the angle between the hanging strip body 31 and the fixing frame 33 by means of the angle fixing screw 36 at the 0-degree and 10-degree positions, with 20 degrees being the maximum limit position.

[0064] In summary, the wall-mounting mechanism of this utility model can horizontally connect and fix multiple displays to a wall, and can be adjusted horizontally and backward within a certain range. The height and backward adjustment functions of the wall-mounting mechanism are integrated into the wall panel assembly; the mounting bracket of the wall-mounting mechanism also has a tilt angle adjustment function. The height and backward adjustment structure of the wall panel assembly of the wall-mounting mechanism of this utility model are less prone to displacement, and the manufacturing process is simple and cost-effective; in addition, the mounting bracket of the wall-mounting mechanism can prevent the tilt adjustment structure from easily changing during angle adjustment, making the tilt adjustment more precise.
