Description

Technical Field

[0001] The utility model relates to a wall-mounted mounting mechanism for a display, and more particularly to a spliced screen bracket for a flat-panel display and similar devices. Background Art

[0002] Liquid crystal displays (LCDs), also known as flat panel displays, are typically mounted on the walls of places like restaurants and shopping malls to provide viewers with dynamically changing, updatable information. In recent years, with the widespread use of large-screen LCDs in public areas like restaurants, shopping malls, and airports, there has been an urgent need for wall mounts that can connect single or multiple displays and secure them to the wall.

[0003] Flat-panel monitors are popular with users primarily due to their relatively thin thickness, light weight, and large size. Currently, wall-mount brackets for flat-panel monitors are also becoming larger as flat-panel monitors become larger. Furthermore, to save space, retractable or foldable brackets that slide in and out of the wall have become available. However, existing wall-mount monitor brackets are primarily manually extended or retracted relative to the wall, making them inconvenient and less user-friendly due to their increasing size and weight. Furthermore, if the center bracket of a video wall, such as a 3x3 or 4x4 video wall, breaks and requires repair, unless it uses a pop-up bracket or the latch on the pop-up bracket fails and becomes stuck, repairs must be performed starting from the outside and working back to the center. These brackets are known as front-of-the-wall maintenance brackets. Utility Model Content

[0004] Based on this, it is necessary to provide a splicing screen bracket whose wall panel components can automatically pop out from a folded state relative to the wall.

[0005] The splicing screen bracket involved in one embodiment of the present utility model is characterized in that it includes:

[0006] Wall panel components, used for fixing to the wall;

[0007] A display mounting assembly, which is used to fix the display screen;

[0008] a connecting component foldably disposed between the wall panel component and the display hanging assembly, so that the display hanging assembly moves toward the direction approaching the wall panel component or moves away from the wall panel component;

[0009] a locking component, mounted on the display hanging assembly or the wall panel component, for locking the display hanging assembly on the wall panel component; and

[0010] A locking portion is mounted on the wall panel component or the display hanging assembly at a position corresponding to the locking component and is connected to the locking component in a snap-on manner.

[0011] When the locking component and the locking portion are engaged with each other, the display hanging assembly is in a locked state relative to the wall panel component;

[0012] When the locking component is unlocked from the locking portion, the display hanging assembly automatically pops out in a direction away from the wall panel component.

[0013] Furthermore, the locking component includes a rotatable bolt.

[0014] When the locking member is pressed, the door bolt rotates relative to the locking portion to be locked in the locking portion and enter a locked state;

[0015] When the locking component is pressed again, the door bolt rotates relative to the locking portion to disengage from the locking portion and enter an unlocked state.

[0016] Furthermore, two elastic columns are further provided on both sides of the locking portion on the wall panel component.

[0017] The elastic column includes a bolt, a sleeve sleeved on a portion of the outer circumference of the bolt, and an elastic member sleeved on the bolt.

[0018] When the door bolt is locked in the locking portion, the elastic members of the two elastic columns are compressed toward the wall panel component, thereby accumulating elastic potential energy.

[0019] Furthermore, the locking component further includes:

[0020] a cam mechanism fixed to the display mounting assembly;

[0021] abutting columns for abutting the wall panel components; and

[0022] An elastic member, one end of which abuts against the display hanging assembly and the other end is fixed in the abutting column.

[0023] The door bolt is installed at the end of the abutting column.

[0024] Furthermore, the cam mechanism includes an inner cam,

[0025] The peripheral wall of the inner cam has a plurality of wave crests and wave troughs arranged at intervals.

[0026] Sliding columns protruding in different directions are arranged at intervals on the outer peripheral wall of the abutting column.

[0027] The sliding column slides between adjacent wave crests and wave troughs, thereby driving the abutting column to rotate relative to the cam mechanism.

[0028] The elastic member provides a torsional force for rotating the abutting column and counteracts the reverse force from the wall panel component.

[0029] Furthermore, the connecting component includes a first hinge shaft, a second hinge shaft, and a first connecting rod portion and a second connecting rod portion that are arranged to cross each other.

[0030] One end of the first link portion is slidably mounted on the display hanging assembly via the first hinge shaft, and the other end of the first link portion is rotatably mounted on the wall panel component;

[0031] One end of the second link portion is slidably mounted on the wall panel component via the second hinge shaft, and the other end of the second link portion is rotatably mounted on the display hanging assembly.

[0032] Furthermore, the side wall of the wall panel component is provided with a guide groove, and the side wall of the display hanging assembly is provided with a guide groove,

[0033] The one end of the first link portion is slidably mounted in the guide groove of the display mounting assembly via the first hinge shaft.

[0034] The one end of the second link portion is slidably mounted in the guide groove of the wall panel component through the second hinge shaft.

[0035] The first link portion and the second link portion move toward a direction of overlapping or separating with each other under the guidance of the respective guide grooves.

[0036] Furthermore, the connecting component further comprises an elastic member, one end of the elastic member is fixed to the second hinge shaft, and the other end of the elastic member is fixed to the lower half of the fixing rod of the wall panel component.

[0037] When the first connecting rod portion and the second connecting rod portion are separated, the elastic member is in a naturally contracted state;

[0038] When the first link portion and the second link portion overlap, the elastic member is in a stretched state;

[0039] The second connecting rod portion slides up and down in the guide groove due to the action of the elastic member.

[0040] Furthermore, the splicing screen bracket also includes a fine-tuning mechanism.

[0041] The fine-tuning mechanism is arranged at the four corners of the display hanging assembly, and can fine-tune the distance of the display hanging assembly in the front-back, horizontal and left-right directions.

[0042] Furthermore, each of the fine-tuning mechanisms includes a front-to-back adjustment portion, a horizontal adjustment portion, and a left-to-right adjustment portion.

[0043] The front-rear adjustment portion includes a cube-shaped first frame, a stepped fixing plate connected to one side of the first frame, and a front-rear adjustment nut fixed on the fixing plate;

[0044] The horizontal adjustment portion includes a second cube-shaped frame, a stepped connecting plate connected to one side of the second frame, a horizontal adjustment nut protruding upward from the second frame, and a connecting shaft;

[0045] The left and right adjustment part includes a long screw and a left and right adjustment nut sleeved on the long screw;

[0046] The first frame is sleeved in the second frame, and the fixing plate is arranged on the inner side of the connecting plate in parallel and at a certain distance;

[0047] The screw portion of the front and rear adjustment nut passes through the connecting plate and the fixing plate at the same time.

[0048] The front-to-back adjustment nut drives the fixing plate to move forward and backward relative to the connecting plate, thereby making the fixing plate move closer to or farther away from the connecting plate to adjust the distance between the two;

[0049] One end of the long screw is passed through and fixed to the other end of the fixing plate opposite to the position of the front and rear adjustment nut.

[0050] The screw portion of the horizontal adjustment nut passes through the connecting shaft and is screwed together with the connecting shaft. The screw portion is pulled up and down by rotating the horizontal adjustment nut, thereby achieving horizontal distance adjustment of the display hanging assembly.

[0051] The connecting shaft is pushed to move left and right in the moving groove of the display hanging assembly by rotating the left and right adjusting nuts, thereby achieving the distance adjustment of the display hanging assembly in the left and right directions.

[0052] Compared with the existing technology, the display hanging bracket in the splicing screen bracket provided by the present invention can perform fine-tuning of the horizontal, front-back and left-right positions within a certain range, and concentrates the left-right fine-tuning, front-back fine-tuning and horizontal fine-tuning functions on the left and right sides of the display hanging bracket, making the functions more complete and the structure more reasonable; in addition, the present invention adopts a new rebound lock structure. When the display needs to be maintained, the display hanging bracket can be automatically popped out by pressing both sides, which makes the operation simpler and smoother, and thus makes the installation and maintenance of the display more convenient.

DETAILED DESCRIPTION

[0064] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0065] In addition, the terms “first” and “second” are only used to distinguish components and cannot be understood as indicating or implying relative importance or indicating the number of technical features.

[0066] The specific implementation methods of the present application will be described in further detail below with reference to the accompanying drawings.

[0067] The splicing screen bracket 100 of the present invention is used to mount multiple flat-panel displays on a wall and can be adjusted horizontally, front-to-back, and left-to-right within a certain range. Furthermore, during maintenance, the splicing screen bracket 100 can be unlocked by pressing it, automatically popping out from the wall, and locked to the wall panel by pressing it again.

[0068] Specifically, please see Figures 1 to 3The splicing screen bracket 100 includes a wall panel component 10, a display hanging component 20, a connecting component 30, a locking component 40 and a hanging bar component 50.

[0069] The wall panel component 10 is a rectangular or square frame that is fixed to a wall surface such as a wall surface by fasteners such as screws. The wall panel component 10 includes a reinforcing plate 11 and two fixing rods 12 extending in the vertical direction. The reinforcing plate 11 extends in the horizontal direction and is vertically connected to the middle position of each of the two fixing rods 12. Figure 1 As shown, two elastic columns 13 are spaced apart on the front side (facing the flat panel display) of the reinforcement plate 11. Each elastic column 13 includes a bolt, a sleeve 131 sleeved on a portion of the outer periphery of the bolt, an elastic member (a coil spring in this embodiment) 133 sleeved on the screw portion of the bolt, an inner nut 135 abutting against the reinforcement plate 11, and an outer nut 137 fixed to the outer surface of the reinforcement plate 11. When the sleeve 131 is pressed toward one end of the display hanging assembly 20, the sleeve 131 pushes the elastic member 133 toward the reinforcement plate 11, thereby compressing the elastic member 133 to accumulate elastic potential energy. Figure 2 As shown, a locking portion 15 is further provided between the two elastic columns 13 on the reinforcing plate 11 to cooperate with the locking component 40. The locking portion 15 includes two L-shaped locking pieces 151 and a bottom plate 153. The two L-shaped locking pieces 151 are respectively bent and extended from the opposite sides of the bottom plate 153. Figure 8 As can be seen, two L-shaped locking pieces 151 are spaced apart and arranged opposite each other, forming a receiving space 150. An opening (not shown) is formed between the free ends of the two locking pieces 151 (i.e., between the sides of the two locking pieces 151 away from the bottom plate 153). A circular through-hole 156 is formed in the center of the bottom plate 153.

[0070] The display mounting assembly 20 is a rectangular or square frame that is slightly larger than the wall panel component 10 and is used to fix and support a flat-panel display. The display mounting assembly 20 includes two upper and lower hanging beams 21, a fixed beam 23 located in the middle of the two hanging beams 21 and parallel to the two hanging beams 21, support rods 25 perpendicularly connected to the opposite ends of the fixed beams 23, and fine-tuning mechanisms 27 located at the four corners of the display mounting assembly 20. The two hanging beams 21 are rail-shaped rods with openings facing in opposite directions, the fixed beam 23 and the support rods 25 are slender, lightweight plates, and the four fine-tuning mechanisms 27 are located at the upper and lower ends of each support rod 25. The fine-tuning mechanisms 27 are located at the upper and lower ends of the left and right connecting components 30 and are used to fine-tune the display mounting assembly 20 in the front-back, horizontal, and left-right directions.

[0071] Two connecting members 30 are connected between the wall panel 10 and the display mount assembly 20, respectively, to facilitate the retraction and extension of the display mount assembly 20 toward and away from the wall panel 10. Each connecting member 30 is X-shaped and includes a first link portion 31 and a second link portion 32 arranged crosswise. The upper end of the first link portion 31 is slidably mounted within a guide slot 253 in the side wall 251 of the support rod 25 of the display mount assembly 20 via a first hinge axis 33. The lower end of the first link portion 31 is rotatably mounted to the lower end of the fixed rod 12 of the wall panel 10. The upper end of the second link portion 32 is slidably mounted within a guide slot 123 in the side wall 121 of the fixed rod 12 of the wall panel 10 via a second hinge axis 34. The lower end of the second link portion 32 is rotatably mounted to the lower end of the support rod 25 of the display mount assembly 20 and is located above the fine-tuning mechanism 27. One end of an elastic member 35 is hooked onto the middle portion of the second hinge shaft 34, and the other end of the elastic member 35 is fixed to the tab 122 of the fixing rod 12 of the wall panel component 10. The display mounting assembly 20 and the wall panel component 10 are arranged parallel to each other in the front-to-back direction facing the user. When the upper ends of the first connecting rod 31 and the second connecting rod 32 slide along the guide grooves 253 and 123 to the upper ends of the fixing rod 12 and the support rod 25, respectively, the two connecting members 30 are contracted and overlapped, and the display mounting assembly 20 is retracted relative to the wall panel component 10. At this time, the elastic members 35 on both sides of the wall panel component 10 are stretched, thereby accumulating elastic potential energy. On the contrary, due to the elastic restoring force of the elastic member 35, the upper ends of the first connecting rod portion 31 and the second connecting rod portion 32 slide to the lower ends of the guide groove 123 and the guide groove 253 respectively, so that the two connecting parts 30 are pulled apart and then in an expanded state; at this time, the elastic members 35 on both sides of the wall panel component 10 are elastically reset, and the display hanging assembly 20 is in an expanded state pulled forward relative to the wall panel component 10.

[0072] See below Figure 4 , the specific structure and function of the fine-tuning structure 27 of the splicing screen bracket 100 of the present invention are further described. Figure 4As shown, a fine-adjustment structure 27 is fixed to each of the upper and lower ends of the support rods 25 on either side of the display mounting assembly 20. Each fine-adjustment mechanism 27 includes a fore-aft adjustment section, a horizontal adjustment section, and a left-right adjustment section. The fore-aft adjustment section comprises a cube-shaped first frame 2710, a stepped fixing plate 2711 connected to one side of the first frame 2710, and a fore-aft adjustment nut 2713 fixed thereto. The horizontal adjustment section comprises a cube-shaped second frame 2730, a stepped connecting plate 2731 connected to one side of the second frame 2730, a horizontal adjustment nut 2733 protruding upward from the upper plate of the second frame 2730, and a screw portion (not shown) connected to the horizontal adjustment nut 2733. The left-right adjustment section comprises a long screw 2750 and a left-right adjustment nut 2751 mounted thereon. The first frame 2710 is slightly smaller than the second frame 2730 and fits within it. The front (user-facing) and rear panels of the first and second frames 2710 and 2730 are each provided with longitudinally extending through-holes 28. The through-holes 28 on the front and rear panels of the first frame 2710 and the second frame 2730 are of identical size and correspondingly positioned. A fixing plate 2711 is positioned parallel to and spaced a certain distance from the inner side of the connecting plate 2731. The screws of the front and rear adjustment nuts 2713 pass through both the connecting plate 2731 and the fixing plate 2711. The lower plate of the second frame 2730 is secured to the upper end of the support rod 25 using screws or other means. One end of a long screw 2750 is inserted through and fixed to the fixing plate 2711, opposite the end of the front and rear adjustment nuts 2713. The horizontal adjustment unit further includes a connecting shaft 2735, the screw of which passes through the connecting shaft 2735 and screws into a threaded hole in the connecting shaft 2735 (not shown). The upper side of the display mount assembly 20 features a rail-shaped crossbar 21, one end of which passes through the second frame 2730. The front and rear sidewalls of the rail groove of the crossbar 21 are provided with movable slots 210 for receiving the front and rear ends of a connecting shaft 2735. After passing through the movable slots 210, the ends of the connecting shaft 2735 are further received in through-holes 28 formed in the front and rear side panels of the first and second frames 2710 and 2730. These through-holes 28 allow the ends of the connecting shaft 2735 to move vertically, allowing for fine-tuning of the vertical position of the display mount assembly 20.

[0073] When using the four fine-tuning structures 27 to adjust the front-to-back position of the display mount assembly 20, rotating the knob portion of the front-to-back adjustment nut 2713 causes the screw portion of the nut to move the fixing plate 2711 back and forth relative to the connecting plate 2731. This allows the fixing plate 2711 to move closer to or further away from the connecting plate 2731 to adjust the distance between them, thereby achieving fine-tuning of the overall front-to-back position of the display mount assembly 20. It should also be noted that to maintain consistent flatness at all four corners, the four fine-tuning structures 27 must be adjusted back and forth by the same amount.

[0074] To adjust the horizontal position of the display mount assembly 20 using the four fine-tuning structures 27, the two upper horizontal adjustment nuts 2733 on the left and right sides are rotated, and by pulling the screws up and down, the connecting shafts 2735 are moved up and down within their corresponding through holes 28 to achieve horizontal adjustment of the display mount assembly 20. To adjust the horizontal position, the two lower horizontal adjustment nuts 2733 are loosened first, and then the two upper horizontal adjustment nuts 2733 are rotated. After the display mount assembly 20 reaches balance and moves into position, the two lower horizontal adjustment nuts 2733 are tightened again.

[0075] When using the four fine-tuning structures 27 to adjust the position of the display hanging assembly 20 in the left and right directions, rotate the four left and right adjustment nuts 2751 on the left and right sides to push the connecting shaft 2735 to move left and right in the moving groove 210 of the hanging beam 21, thereby achieving fine-tuning of the left and right position of the display hanging assembly 20.

[0076] See Figures 5 to 8 The locking component 40 is fixed at a roughly middle position of the fixed beam 23 and is used in conjunction with the reinforcing plate 11 of the wall panel component 10 so that the display hanging assembly 20 can automatically pop out relative to the wall panel component 10.

[0077] The locking component 40 includes a chassis 41, a cam mechanism 42, an elastic member 43, a support column 44, and a bolt 45. The chassis 41 is a disc structure, and a plurality of fixed cylinders 410 are arranged at intervals along the circumference thereof. The chassis 41 is fixedly mounted on the fixed beam 23.

[0078] The cam mechanism 42 includes an inner cam 423 and a stopper 421 that cooperate with each other. The inner cam 423 is sleeved and mounted within the stopper 421. The circumferential wall of the inner cam 423 is spaced apart with a plurality of sawtooth-shaped peaks 4231, with a plurality of troughs 4233 correspondingly formed between the peaks 4231. The stopper 421 has a hollow portion 4210.

[0079] One end of the elastic member 43 passes through the inner cam 423 and abuts against the fixed beam 23. Specifically, one end of the elastic member 43 is received within the hollow portion 4210 of the retaining cylinder 421. The other end of the elastic member 43 is received and secured within the hollow cavity of the abutting post 44. The elastic member 43 provides a torsional force that rotates the abutting post 44 and counteracts the opposing force from the wall panel 10.

[0080] The push-up column 44 is vertically extended in a direction away from the chassis 41 relative to the plane where the chassis 41 is located. Four sliding columns 441 protruding in different directions are arranged at intervals on the outer peripheral wall of the push-up column 44 at one end close to the chassis 41. The push-up column 44 is accommodated in the space formed by the multiple peaks 4231 of the inner cam 423. In the initial state, its sliding column 441 is engaged in the trough 4233 between the multiple peaks 4231. An abutment joint 46 is fixed to the end of the push-up column 44 away from the chassis 41, and the abutment joint 46 abuts the reinforcement plate 11 of the wall panel component 10. The abutment joint 46 is composed of an integrally formed semicircular sphere and a hexagonal nut. The hexagonal nut and the threaded column 440 formed on the end face of the push-up column 44 are screwed together to form the abutment joint 46.

[0081] The bolt 45 is sleeved on the outer periphery of the threaded column 440 and sandwiched between the end surface of the abutting head 46 and the abutting column 44, and can play a role similar to a gasket, and is used to stop and position the lock component 40 in the locking part 15. The bolt 45 can rotate relative to the locking part 15 to achieve unlocking and locking states. In addition, please refer to Figure 2 and Figure 3 When the display mounting assembly 20 is extended relative to the wall panel 10, the bolt 45 extends in a direction perpendicular to the length of the fixed beam 23 and the reinforcing plate 11. This allows the bolt 45 to be easily received in the receiving space 150 through the opening of the locking portion 15.

[0082] Furthermore, two fixing posts (not shown) are provided on the fixed beam 23, on either side of the inner cam 423. During installation, these fixing posts are screwed or snapped into the fixed barrel portion 410 of the chassis 41 through a threaded or interference fit. Furthermore, the fixed barrel portions 410 on the chassis 41, located above and below the retaining barrel portion 421, are designed to engage screws or other devices to secure the chassis 41 to the fixed beam 23 of the display mount assembly 20.

[0083] See below Figures 5 to 7The functional principle of the locking component 40 of the present invention will be explained. When a user grasps the support rods 25 on both sides of the display mount assembly 20 and pushes toward the wall panel 10, the unfolded connecting component 30 is folded and gathered together, thereby allowing the abutment 46 of the locking component 40, which is fixed to the inner surface of the fixed beam 23 of the display mount assembly 20, along with the bolt 45, to enter the locking portion 15 located on the reinforcing plate 11 of the wall panel 10. As the user continues to push, the abutment 46 enters the through-hole 156 of the locking portion 15 and is ultimately held against the surface of the reinforcing plate 11. At this point, the abutting post 44 of the lock component 40, under the reverse force from the reinforcing plate 11, compresses the elastic member 33 while retracting into the hollow portion 4210 of the limiting cylinder 421. The sliding post 441 on the outer periphery of the abutting post 44 slides between adjacent crests 4231 of the inner cam 423, causing the abutting post 44 to twist relative to the inner cam 423, simultaneously driving the bolt 45 to a horizontal position within the receiving space 150 of the locking portion 15, parallel to the longitudinal direction of the reinforcing plate 11. At this point, the elastic member 43 is further compressed, and the elastic members 133 of the two elastic posts 13 on the reinforcing plate 11 are simultaneously compressed toward the reinforcing plate 11, thereby accumulating elastic potential energy. At this time, if the user lets go, the two ends of the door bolt 45 in the horizontal state will be engaged with the inner surface of the ends of the two L-shaped locking pieces 151 of the locking part 15, thereby fixing the display hanging assembly 20 in a locked state relative to the wall panel component 10.

[0084] The working principle of the cam mechanism 42 is further explained as follows. When the push column 44 of the lock component 40 is subjected to a reverse push force from the reinforcing plate 11, the sliding column 441 on the outer periphery of the push column 44 slides clockwise from the trough 4233 of the inner cam 423 along the inclined surface, passes over the trough 4233 and falls into the trough 4233 of the adjacent wall, thereby rotating the push column 44 90 degrees. At this time, the door bolt 45 changes from a vertical placement to a horizontal placement, thereby achieving the locking of the lock component 40 relative to the locking part 15. After that, the user can just let go. Press once and the door bolt rotates 90°, from open to closed, and the cycle continues.

[0085] When it is necessary to unlock the locking component 40 relative to the locking portion 15, the user presses the display hanging assembly 20 toward the wall panel component 10 again, so that the abutment 46 of the locking component 40 abuts the reinforcement plate 11 again, and the abutment column 44 is elastically reset in the counterclockwise direction under the action of the elastic member 43, and the door bolt 45 is converted from horizontal placement to vertical placement. After the user lets go, under the elastic force of the elastic member 43 of the locking component 40, the two elastic columns 13 of the wall panel component 10 and the elastic force of the two elastic members 35 of the connecting component 30, the display hanging assembly 20 automatically pops out in the direction away from the wall panel component 10 until the two second connecting rod portions 32 of the connecting component 30 slide and stop at the lower end of the guide groove 123 of the wall panel component 10.

[0086] Figure 8 The latch 40 and the locking portion 15 are shown mating with each other. The latch 40 is housed within the receiving space 150, with its ends abutting the inner surfaces of the two locking tabs 151. The abutting head 46 of the abutting post 44 is housed within a through-hole 156 in the bottom plate 153 of the locking portion 15, contacting the reinforcing plate 11 via the through-hole 156.

[0087] The hanging bar assembly 50 includes two hanging bars 51 , and the upper and lower ends of each hanging bar 51 are clamped and fixed to the upper and lower hanging bar beams 21 of the display hanging assembly 20 for hanging a flat panel display.

[0088] To sum up, the display hanging bracket in the splicing screen bracket provided by the present invention can perform fine-tuning of the horizontal, front-back and left-right positions within a certain range, and concentrates the left-right fine-tuning, front-back fine-tuning and horizontal fine-tuning functions on the left and right sides of the display hanging bracket, making the functions more complete and the structure more reasonable; in addition, the present invention adopts a new rebound lock structure. When the display needs to be maintained, the display hanging bracket can be automatically popped out by pressing both sides, which makes the operation simpler and smoother, and thus makes the installation and maintenance of the display more convenient.

[0089] In addition, as a variation of the present invention, the positions of the locking component 40 and the locking portion 15 can also be interchanged. That is, the locking component 40 can be arranged on the wall panel 10, and the locking portion 15 can be arranged on the display mounting assembly 20 at a position corresponding to the locking component 40, thereby achieving locking and unlocking of the display mounting assembly 20 relative to the wall panel 10.
