Description

Technical Field

[0001] This utility model relates to the field of fixing devices, and in particular to a wall-mounting device for a large display. Background Technology

[0002] Large-format monitors are increasingly used in modern offices, commercial displays, and home entertainment settings. To save space, enhance the user experience, and meet specific display needs, wall mounting has become a common installation method. However, existing wall-mounted mounting systems for large monitors have several inconveniences. During installation, the large size and weight of the monitor make it difficult for operators to accurately position and install it onto the mounting device. Traditional mounting methods require rotating the monitor to a vertical position and lifting it to a certain height so that the insertion part on the back of the monitor aligns with the positioning part on the wall. The mounting device is positioned between the back of the monitor and the wall, making observation difficult, and installation failure could damage the monitor. Therefore, existing mounting systems need to be optimized. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a wall-mounted device for large displays, which solves the problem that placing the mounting device on the back wall of the display is not conducive to observation and affects installation.

[0004] According to an embodiment of this utility model, a wall-mounted device for a large display includes a support base, a rotating positioning block, and a limiting component. The support base is fixedly mounted on the wall, and a mounting hole is provided on the top of the support base. The downward-facing side of the rotating positioning block is rotatably connected to the mounting hole, and a positioning groove is provided on the upward-facing side of the rotating positioning block. A positioning element adapted to the positioning groove is provided on the bottom of the display. The rotating positioning block can rotate between a vertical state and a state tilted away from the wall. The rotating positioning block can extend and retract in a direction perpendicular to its own rotation axis. The limiting component is respectively provided on the rear wall of the display and the wall and is located above the support column, so that the display remains in a vertical state.

[0005] The technical principle of this utility model is as follows: during installation, the bottom positioning part of the non-vertical display is first aligned with the positioning groove of the rotating positioning block. When the display is rotated to the vertical position, the rotating positioning block retracts, causing the bottom of the display to contact the top surface of the support base. The limiting component makes the display stable and stationary after it is rotated to the vertical position.

[0006] As a preferred embodiment, the limiting component includes a connecting block, a rotating block, a torsion spring, and a limiting block. The connecting block is fixedly mounted on the rear wall of the display. An upper right-angled triangular block is provided on the bottom surface of the connecting block away from the display, with the vertical surface of the upper right-angled triangular block facing the display. One side of the rotating block is rotatably connected to the wall. The rotating block rotates between a horizontal state and a downward tilt. The torsion spring is used to keep the rotating block in a horizontal state. A lower right-angled triangular block is provided on the top surface of the rotating block away from the wall, with the vertical surface of the lower right-angled triangular block facing the wall. The position of the lower right-angled triangular block corresponds to the movement path of the upper right-angled triangular block. The limiting block is fixedly connected to the wall. When the display is in a vertical state, the limiting block is located at the gap between the connecting block and the wall and its size is adapted to the gap.

[0007] As a preferred embodiment, the rotary positioning block is provided with a sliding groove and a sliding part. The downward side of the sliding groove is rotatably connected to the bottom of the mounting hole, and the upward side of the sliding part is provided with a positioning groove. The sliding groove and the sliding part are slidably engaged, and the sliding direction of the sliding part is perpendicular to the rotation axis of the rotary positioning block. Several springs are arranged in parallel inside the sliding groove. One end of the spring is fixedly connected to the bottom of the sliding groove, and the other end of the spring is fixedly connected to the end face of the sliding part.

[0008] As a preferred arrangement, the limiting components are symmetrically arranged on the left and right sides of the display and located at the top and center.

[0009] As a preferred feature, the top surface of the support base is provided with a rubber layer.

[0010] As a preference, the maximum rotation angle of the rotating positioning block is less than forty-five degrees.

[0011] As a preferred arrangement, the support bases are respectively located on both sides of the bottom of the display, with a gap between the two support bases.

[0012] As a preferred option, a triangular support structure is provided between the top surface of the support base and the wall.

[0013] Compared to existing technologies, this invention offers the following advantages: When the monitor is tilted, more people can lift it from the left and right sides; when the monitor is close to the wall, the field of vision is better; and the positioning grooves of the bottom positioning component and the rotating positioning block are more precisely matched. Workers only need to rotate the monitor to a vertical position, and the limiting component will then limit the monitor's position. This reduces the difficulty of operation, allowing even non-professionals to easily complete the initial installation. The rotating positioning block has a telescopic structure; when the monitor is vertical, gravity causes the rotating positioning block to retract, and the bottom of the monitor contacts the support base, increasing the stability of the monitor after installation. The support base is horizontally fixed to the wall, providing solid support for the monitor. Attached Figure Description

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1As shown in the figure, this utility model embodiment proposes a wall-mounted device for a large display, including a support base 7, a rotating positioning block 5, and a limiting component. The support base 7 is fixedly mounted on a wall 8 by expansion screws. The top of the support base 7 has a mounting hole 12. The downward-facing side of the rotating positioning block 5 is rotatably connected to the mounting hole 12. The bottom of the rotating positioning block 5 has a semi-circular structure, and the bottom edge of the mounting hole 12 has a semi-circular groove. The matching design of the semi-circular structure at the bottom of the rotating positioning block 5 and the semi-circular groove at the bottom edge of the mounting hole 12 achieves precise and stable positioning, prevents offset, reduces rotational resistance, and ensures flexible rotation. The upward-facing side of the rotating positioning block 5 has a positioning groove 6, and the opening end of the positioning groove 6 has an inlet angle. The bottom of the display 1 has a positioning component adapted to the positioning groove 6, which is fixed to the bottom of the display 1 by screws. The rotating positioning block 5 can rotate between a vertical position and a position tilted away from the wall 8. When the top of the rotating positioning block 5 is tilted away from the wall 8, the positioning groove 6 on the top faces outward, making it easy for the operator to align the positioning component at the bottom of the monitor 1 with the positioning groove 6. The rotating positioning block 5 can extend and retract in a direction perpendicular to its own rotation axis. When the rotating positioning block 5 is in a vertical position and the opening of the positioning groove 6 faces upward, it corresponds to the final installation state of the monitor 1. The limiting components are respectively set on the rear wall of the monitor 1 and the wall 8 and are located above the support column, so that the monitor 1 remains in a vertical position. After the positioning component at the top of the monitor 1 and the positioning groove 6 are engaged, the monitor 1 rotates to a vertical position, and the limiting components limit the monitor 1, so that the monitor 1 cannot rotate further.

[0021] like Figure 4As shown, as a preferred embodiment, the limiting assembly includes a connecting block 2, a rotating block 3, a torsion spring, and a limiting block 4. The connecting block 2 is fixedly mounted on the rear wall of the display 1. An upper right-angled triangular block 13 is provided on the bottom surface of the connecting block 2 away from the display 1, with its vertical surface facing the display 1. One side of the rotating block 3 is rotatably connected to the wall 8. The rotating block 3 rotates between a horizontal state and a downward tilt. The torsion spring is used to keep the rotating block 3 horizontal and is sleeved on the rotation axis of the rotating block 3. A lower right-angled triangular block 14 is provided on the top surface of the rotating block 3 away from the wall 8, with its vertical surface facing the wall 8. The position of the lower right-angled triangular block 14 corresponds to the movement path of the upper right-angled triangular block 13. The limiting block 4 is fixedly connected to the wall 8. When the display 1 is in a vertical state, the limiting block 4 is located at the gap between the connecting block 2 and the wall 8 and its size is adapted to the gap. When monitor 1 rotates to a vertical position, the inclined surface of the upper right-angled triangular block 13 on the rear wall of monitor 1 contacts the inclined surface of the lower right-angled triangular block 14, causing the rotating block 3 to rotate downwards. When monitor 1 rotates to a vertical position, the inclined surface of the upper right-angled triangular block 13 disengages from the inclined surface of the lower right-angled triangular block 14, making the vertical surfaces of the upper right-angled triangular block 13 and the lower right-angled triangular block 14 parallel and aligned. When the top of monitor 1 tilts away from the wall 8, the upper right-angled triangular blocks 13 and 14 prevent monitor 1 from rotating. When monitor 1 is in a normal vertical position, the limiting block 4 is engaged in the gap between the connecting block 2 and the wall 8, limiting the continued forward rotation of monitor 1 and keeping it stable. The inclined surfaces of the upper right-angled triangular block 13 and 14 are smooth surfaces. The rotating block 3 is connected to the limiting block 4 and a mounting plate on the wall 2.

[0022] like Figure 2 As shown, as a preferred embodiment, the rotating positioning block 5 is provided with a sliding groove 10 and a sliding part 9. The downward-facing side of the sliding groove 10 is rotatably connected to the bottom of the mounting hole 12, and the upward-facing side of the sliding part 9 is provided with a positioning groove 6. The sliding groove 10 and the sliding part 9 are slidably engaged, and the sliding direction of the sliding part 9 is perpendicular to the rotation axis of the rotating positioning block 5. Several springs 11 are arranged side by side inside the sliding groove 10. One end of the spring 11 is fixedly connected to the bottom of the sliding groove 10, and the other end of the spring 11 is fixedly connected to the end face of the sliding part 9. When the sliding groove 10 is a long strip structure, corresponding springs 11 are arranged side by side inside it according to the length of the sliding groove 10. If the length of the sliding groove 10 is short, only one spring 11 can be provided. When the display 1 rotates to a vertical position, the spring 11 contracts under the action of gravity, causing the bottom of the display 1 to contact the top surface of the support base 7, increasing the support area of ​​the bottom of the display 1 and making the display 1 more stable.

[0023] As a priority, the limiting components are symmetrically arranged on the left and right sides of the display 1 and located at the top and middle, so that the display 1 is evenly supported, effectively preventing it from shaking or shifting, and ensuring stable installation and safe use.

[0024] As a preferred feature, the top surface of the support base 7 is provided with a rubber layer. The rubber layer can both cushion the impact force when the display 1 is placed to prevent damage and increase the friction to prevent it from sliding, thus ensuring stability during use.

[0025] As a priority, the maximum rotation angle of the rotating positioning block 5 is less than 45 degrees. This maximum rotation angle of the rotating positioning block 5 is less than 45 degrees, which not only meets the reasonable angle adjustment requirements of the display 1, but also avoids damage from excessive force on the components, prevents collisions, ensures safe installation and use, and improves operational convenience and accuracy. The two side walls of the mounting hole 12 limit the rotation of the rotating positioning block 5.

[0026] like Figure 3 As shown, as a priority, the support bases 7 are respectively arranged on both sides of the bottom of the display 1, with a gap between the two support bases 7. This not only provides stable and balanced support for the display 1, but also leaves space for wiring layout, facilitating installation and maintenance while ensuring safety and stability during use.

[0027] As a priority, a triangular support structure is provided between the top surface of the support base 7 and the wall 8 to improve the stability of the support base 7.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
