[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0033] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0034] Please refer to Figures 1-8. This utility model is a fixing device and display back panel mounting assembly, including a fixing frame 1 and two hanging brackets 2 hanging on the fixing frame 1, and a mounting bracket 3 hinged to the hanging brackets 2 through a rotating shaft 21 and a shaft hole 31. A locking rod 4 is provided between the two hanging brackets 2 and the mounting bracket 3. The two locking rods 4 are connected to each other by a bidirectional screw 5. The lower end of each hanging bracket 2 is hinged to a locking plate 8 by a torsion spring. A swing rod 81 is integrally fixed to the locking plate 8. The two swing rods 81 are connected by a linkage plate 82.

[0035] Furthermore, two locking pins 41 are fixed on the locking rod 4, and the bracket 2 has a through-hole 23 that slides through the locking rod 4. The through-hole 23 also has a locking groove 231 that engages with the locking pins 41. The mounting bracket 3 has an adjustment groove 32 that slides through the locking rod 4. The adjustment groove 32 has a movable locking groove 321 that engages with the locking pins 41. In this embodiment, the locking groove 231 has one set for locking, and the movable locking groove 321 has several sets of locking after angle adjustment along the circumference of the shaft hole 31.

[0036] Furthermore, both ends of the bidirectional lead screw 5 are connected to bidirectional threaded sleeves 51 via threads. The locking rod 4 is also provided with a threaded section that mates with the bidirectional threaded sleeve 51 near the connection end with the bidirectional lead screw 5. The bidirectional lead screw 5 and the locking rod 4 are connected to each other via the threads of the bidirectional threaded sleeve 51. Through the connection formed between the locking rod 4 and the bidirectional lead screw 5 by the bidirectional threaded sleeve 51, the two mounting brackets 3 can be installed according to the width of the monitor back panel. Then, they are connected through the adjustable thread structure of the bidirectional threaded sleeve 51, so that this fixing device can be used for the installation of different models of monitor back panels.

[0037] Furthermore, a support plate 25 is fixed to one side of the bracket 2. A locking spring 6 is provided between the locking rod 4 and the support plate 25 on the same side, and a positioning sleeve 7 is connected to the end of the locking rod 4 near the support plate 25. A first pull rope 71 is connected to the positioning sleeve 7. The outer diameter of the first pull rope 71 is larger than that of the locking rod 4, so that it can abut against the outside of the support plate 25 under the action of the locking spring 6. This is used to ensure that the locking pin 41 and the locking groove 231 and the moving locking groove 321 are accurately inserted. The positioning sleeve 7 and the locking rod 4 are connected by a thread, which is convenient for assembly.

[0038] Furthermore, the two swing arms 81 are connected to the linkage plate 82 by bolts, and one end of the linkage plate 82 is connected to a second pull rope 83. In this embodiment, the linkage plate 82 has various lengths to adapt to different sizes of display back panels. The linkage plate 82 and the swing arms 81 have a screw-operated structure, which facilitates connection during installation.

[0039] Furthermore, the upper and lower ends of the fixing frame 1 are respectively formed with an upper hanging plate 11 and a lower hanging plate 12. The upper end of the hanging frame 2 is formed with a hook 22 to be attached to the upper hanging plate 11. The lower end of the hanging frame 2 is formed with a stop plate 24 and supports the upper end of the lower hanging plate 12. In this embodiment, the pivot 21 is also formed with a movable space that cooperates with the upper hanging plate 11, which facilitates the rotational cooperation of the lower half of the hanging frame 2 after the two are attached. The abutment between the stop plate 24 and the lower hanging plate 12 enhances the installation reliability of the display back panel in the vertical direction.

[0040] Furthermore, the bracket 2 and the locking plate 8 form a space to cooperate with the lower mounting plate 12. When the bracket is connected, the locking plate 8 forms a block at the rear end of the lower mounting plate 12, thereby preventing the monitor from being detached from the front and top, and achieving the purpose of locking after the bracket 2 is connected to the mounting bracket 1, so as to install the back panel of the monitor on the wall.

[0041] This utility model also provides a display back panel mounting assembly, including the fixing device described above.

[0042] It is understood that this utility model can simultaneously control the locking pins of the two locking rods to lock or disengage from the moving locking groove by operating the first pull rope on one side, simplifying the angle adjustment operation and ensuring a stable lock. At the same time, two rotating locking plates linked by the linkage plate and the second pull rope are set at the lower end of the bracket. Only one side needs to pull the second pull rope arranged on the side to disengage the two locking plates at the same time, which is convenient for the staff to operate when moving the monitor from both sides.

[0043] A specific application of this embodiment is as follows: The hanging bracket 2 in the factory state is hinged to the shaft hole 31 on the mounting bracket 3 through the rotating shaft 21. The locking rod 4 near the positioning sleeve 7 passes through the corresponding hanging bracket 2 and mounting bracket 3, and the locking pin 41 and the moving locking groove 321 are locked under the action of the locking spring 6. The locking rod 4 at the other end and the bidirectional lead screw 5 connecting the two locking rods 4 are not connected. The locking plate 8 and the swing rod 81 are connected to the lower end of the hanging bracket 2 through the torsion spring. A snap-in space of the lower hanging plate 12 is formed between the locking plate 8 and the hanging bracket 2. The linkage plate 82 between the two swing rods 81 is not connected. The purpose of the unconnected part is to adapt to the installation position on the back panel of different sized monitors.

[0044] Installation of locking rod 4, bidirectional lead screw 5 and linkage plate 82: Fixing bracket 1 is fixed to the wall with expansion screws. The two mounting brackets 3 are connected to the monitor back panel by threads. At this time, the positions of the two mounting brackets 3 are fixed. Then, the uninstalled locking rod 4 is passed through the adjustment groove 32 and the movable hole 23 to ensure that the locking pin 41 and the movable locking groove 321 on the two locking rods 4 are in the insertion state. Then, the bidirectional lead screw 5 is placed between the two locking rods 4. The two locking rods 4 are connected by rotating the bidirectional threaded sleeve 51 and the screw between it and the locking rod 4. Select the corresponding model of linkage plate 82 and then connect it to the two swing rods 81 by threads.

[0045] Installation of the wall bracket 2, mounting bracket 3, and monitor and mounting frame 1: Two workers lift the monitor, wall bracket 2, and mounting frame 3 from both sides. One worker pulls the second pull rope 83, causing the swing arm 81 and locking plate 8 to rotate. The worker keeps the monitor tilted and first connects the hook 22 to the upper mounting plate 11. Then, along the gap between the hook 22 and the upper mounting plate 11, the monitor is rotated inward so that the abutment plate 24 is supported on the lower mounting plate 12. At this time, the second pull rope 83 is released, and the locking plate 8 and swing arm 81 are rotated and reset under the action of the torsion spring. The locking plate 8 is located at the rear end of the lower mounting plate 12, thereby preventing the monitor from detaching from the front and top.

[0046] Angle adjustment: The positioning sleeve 7 is pulled outward by the first pull rope 71. The positioning sleeve 7 drives the two locking rods 4 to move axially through the double-acting screw 5 and the double-acting threaded sleeve 51. The locking pin 41 is completely disengaged from the moving locking groove 321 and the locking groove 231. The locking spring 6 is compressed. The mounting bracket 3 rotates on the bracket 2 through the shaft hole 31 to adjust the angle. After adjusting to the appropriate position, the first pull rope 71 is released. Under the action of the locking spring 6, the locking pin 41 is inserted into the moving locking groove 321 and the locking groove 231 at the corresponding position to form a lock.

[0047] Removing the monitor back panel: Pull the linkage plate 82 with the second pull rope 83 to rotate the locking plate 8 from the rear end of the lower hanging plate 12 to the lower end. First, pry the lower end of the monitor forward so that the locking plate 8 is completely in front of the fixing bracket 1. Then, lift the monitor up to remove the monitor back panel, the hanging bracket 2, and the mounting bracket 3 from the fixing bracket 1.
