Description

Technical Field

[0001] This utility model relates to the field of monitor bracket technology, and in particular to an adjustable angle sheet metal monitor bracket. Background Technology

[0002] With the rapid development and advancement of electronic technology, traditional CRT monitors have been replaced by flat-panel displays, which are characterized by their thinness, light weight, and small footprint. These are used in electronic products such as flat-panel TVs. Flat-panel monitors are typically mounted on walls or placed on desks using appropriate stands. Using a monitor stand can raise the monitor off the desk, freeing up more space underneath, which is especially important for users with limited desk space or those who need to keep their desks tidy. Stands also allow monitors to be suspended from walls or the edge of desks, further saving space and optimizing the work environment. Monitor stands allow users to adjust the height, tilt angle, and rotation of the monitor according to their personal preferences and work needs, thus providing the best viewing experience.

[0003] An adjustable-angle flat panel display stand disclosed in Chinese patent document CN220506448U includes a first mounting bracket, a first connecting bracket, and a first elastic element. The first connecting bracket is used to connect to the flat panel display. A first locking rod is provided on the first mounting bracket. One end of the first connecting bracket is hinged to the first mounting bracket, and the other end of the first connecting bracket is provided with a row of first grooves that cooperate with the first locking rod. Under the action of the first elastic element, the first locking rod is elastically pressed against the first groove. As the first connecting bracket rotates, the row of first grooves can sequentially cooperate with the first locking rod. This utility model can realize the angle adjustment of the flat panel display. It has a simple and stable structure, is convenient and quick to operate, has high safety, stability and reliability, and reduces costs. It can better meet people's usage needs and expand the application and promotion of the product. However, the adjustable angle of this adjustable-angle flat panel display stand is limited and it is not suitable for large-scale angle adjustments.

[0004] Existing adjustable-angle sheet metal brackets for monitors rely on friction for fixation, which is not durable or strong enough. Over time, friction can lead to material wear or loosening of threads, resulting in failure. Furthermore, the limited angle makes them less applicable.

[0005] To address the shortcomings of the existing technology, providing an adjustable-angle sheet metal bracket for the monitor is a problem worthy of further research. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of existing adjustable angle sheet metal brackets for monitors, which rely on friction for fixation, resulting in insufficient durability and strength. These brackets are prone to failure due to material wear or loosening of threads over time, and their limited angle leads to slightly lower applicability. This utility model provides an adjustable angle sheet metal bracket for monitors, which achieves the technical effect of avoiding loosening and failure due to long-term friction by using serrated meshing.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] An adjustable angle sheet metal bracket for a monitor includes a fixed bracket and an adjustable bracket rotatably connected to the fixed bracket. An angle adjustment mechanism is provided between the fixed bracket and the adjustable bracket. The angle adjustment mechanism includes a limiting plate disposed on the fixed bracket and an angle adjustment disc disposed on the adjustable bracket.

[0009] Both the fixed bracket and the adjusting bracket are U-shaped. The fixed bracket has circular grooves at both ends. The angle adjusting disc is located at both ends of the adjusting bracket. A flanged ring is fixedly connected to the outer side of the center of the angle adjusting disc. The inner diameter of the circular groove matches the inner diameter of the flanged ring. The flanged ring is fitted inside the circular groove. The fixed bracket and the adjusting bracket are rotatably connected through the cooperation of the circular groove and the flanged ring.

[0010] The limiting plates are disposed on both sides of the fixed bracket. The limiting plates are inclined inward and the top of the limiting plates are arc-shaped. The arc surface of the top of the limiting plates is provided with serrated protrusions. The outer side of the angle adjustment disc is fixedly connected to the serrated protrusions. The limiting plates and the angle adjustment disc are engaged by the serrated protrusions. The serrated engagement locking method is more stable than the friction locking method, which can avoid the situation where the friction locking loosens and fails due to long-term use, thereby improving the locking durability of the angle adjustment.

[0011] The outer side of the limiting plate is fixedly connected with a screw, and the two sides of the fixing bracket are fixedly connected with fixing plates. The middle of the fixing plate is provided with a slot, through which the screw passes. A wing nut is threaded onto the screw. The angle can be adjusted and locked by rotating the wing nut. The operation is convenient and the structure is simple.

[0012] The slot is elongated and its width is adapted to the diameter of the screw. The elongated slot can reserve space for misalignment.

[0013] The top serrations of the limiting plate have a chamfer on the outside.

[0014] The limiting plate is made of alloy spring steel. The thickness of the connection between the limiting plate and the fixed bracket is less than the thickness of the main body. The limiting plate automatically rotates inward under its own elastic force to release the locking state.

[0015] Both the fixed bracket and the adjustable bracket have several mounting holes in their middle sections. The fixed bracket is fixedly connected to the desktop or wall through the mounting holes, and the adjustable bracket is fixedly connected to the monitor through the mounting holes.

[0016] 1. The adjustable angle sheet metal bracket of this monitor uses a serrated locking mechanism, which is more stable than the friction locking mechanism. This avoids the problem of the friction locking mechanism loosening and failing after long-term use, thereby improving the locking durability of the angle adjustment.

[0017] 2. The monitor features an adjustable sheet metal bracket. The angle can be adjusted and locked by rotating the wing nut, making it easy to operate and simple in structure.

[0018] 3. The adjustable angle sheet metal bracket for the monitor has a circular groove and a flanged ring between the fixed bracket and the adjustable bracket, which allow the two to rotate and cooperate, so that the adjustable bracket can rotate within a certain angle to adjust the angle of the adjustable bracket and the monitor mounted on the adjustable bracket.

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0025] like Figures 1 to 4As shown, the adjustable angle sheet metal bracket for the monitor includes a fixed bracket 1 and an adjustable bracket 2 rotatably connected to the fixed bracket 1. An angle adjustment mechanism is provided between the fixed bracket 1 and the adjustable bracket 2. The angle adjustment mechanism includes a limiting plate 3 provided on the fixed bracket 1 and an angle adjustment disc 4 provided on the adjustable bracket 2.

[0026] like Figure 1 As shown, both the fixed bracket 1 and the adjusting bracket 2 are U-shaped. Circular grooves 5 are provided at both ends of the fixed bracket 1. Angle adjusting discs 4 are located at both ends of the adjusting bracket 2. Flanged rings 6 are fixedly connected to the outer side of the center of the angle adjusting disc 4. The inner diameter of the circular groove 5 matches the inner diameter of the flanged ring 6. The flanged ring 6 is fitted inside the circular groove 5. The fixed bracket 1 and the adjusting bracket 2 are rotatably connected through the cooperation of the circular groove 5 and the flanged ring 6. By setting the circular groove 5 and the flanged ring 6 between the fixed bracket 1 and the adjusting bracket 2, the two can rotate and cooperate, allowing the adjusting bracket 2 to rotate within a certain angle, thereby adjusting the angle of the adjusting bracket 2 and the monitor mounted on it.

[0027] like Figures 1 to 2 As shown, the limiting plate 3 is disposed on both sides of the fixed bracket 1. The limiting plate 3 is inclined inward, and the top of the limiting plate 3 is arc-shaped. A serrated protrusion is provided in the arc surface of the top of the limiting plate 3. A serrated protrusion is fixedly connected to the outer side of the angle adjusting disc 4. The limiting plate 3 and the angle adjusting disc 4 are engaged by the serrated protrusion. By setting the serrated limiting plate 3 on the fixed bracket 1 and the serrated flanged ring 6 on the adjusting bracket 2, when angle adjustment is required, the limiting plate 3 is inclined inward and engages with the serrated protrusion on the flanged ring 6. When the teeth are misaligned, the flanged ring 6 and even the adjusting bracket 2 are no longer restricted by the meshing of the saw teeth, and the angle can be adjusted. After the angle adjustment is completed, the saw teeth on the limiting plate 3 and the flanged ring 6 are restored to the meshing state. Then, the adjusting bracket 2 is locked in the meshing lock of the saw teeth, so that the adjusting bracket 2 and the display are fixed at the adjusted angle. The locking method of the saw teeth is more stable than the friction locking method, which can avoid the situation that the friction locking will loosen and fail due to long-term use, thereby improving the locking durability of the angle adjustment.

[0028] like Figures 1 to 4As shown, screws 7 are fixedly connected to the outer sides of the limiting plate 3, and fixing plates 8 are fixedly connected to both sides of the fixing bracket 1. A slot 9 is opened in the middle of the fixing plate 8, through which the screws 7 pass. A wing nut 10 is threaded onto the screw 7. By setting the screws 7 with wing nuts 10 on the outer side of the limiting plate 3, when it is necessary to lock the angle of the adjusting bracket 2, the wing nut 10 is rotated. The screws 7 move outward under the threaded action of the wing nut 10, and at the same time, the limiting plate 3 is pulled to rotate inward and outward to cooperate with the serrations on the angle adjusting disc 4, thereby locking the adjusting bracket 2. Angle locking: When the angle of the adjusting bracket 2 needs to be adjusted, the wing nut 10 is rotated in the opposite direction so that the screw 7 no longer pulls the limiting plate 3 outward. Under the action of its own elasticity, the limiting plate 3 tilts inward and is offset from the angle adjusting disc 4. The angle adjusting disc 4 is no longer locked, and the angle can be adjusted. The angle adjustment and locking can be achieved by rotating the wing nut 10. The operation is convenient and the structure is simple. Moreover, the angle adjustment mechanism can be set on only one side as needed, avoiding the situation that both angle adjusting discs 4 need to be locked when adjusting the angle.

[0029] Furthermore, the screw 7 is fixedly connected to the limiting plate 3 by riveting or welding, so that when the wing nut 10 is threadedly connected to the screw 7, the upper limiting plate 3 can be pulled to adjust the tilt angle during the process of pulling the screw 7.

[0030] like Figures 3 to 4 As shown, the slot 9 is elongated, and the width of the slot 9 is adapted to the diameter of the screw 7. By setting the slot 9 to be elongated, it can reserve space for the misalignment of the screw 7 and the wing nut 10 caused by the tilting and rotation of the limiting plate 3. Example 2

[0031] The top serrations of the limiting plate 3 are chamfered. By setting the chamfer on the outside of the serrations of the limiting plate 3, when the limiting plate 3 is pulled outward and engages with the serrated protrusions on the angle adjustment disc 4, the chamfered slope can play a guiding role, making the engagement of the limiting plate 3 and the angle adjustment disc 4 smoother and more convenient. Example 3

[0032] like Figures 1 to 2 As shown, the limiting plate 3 is made of alloy spring steel. The thickness of the connection between the limiting plate 3 and the fixed bracket 1 is less than the thickness of the main body. By using the limiting plate 3 made of alloy spring steel, it has sufficient elasticity and can automatically rotate inward under its own elastic force when the screw 7 releases the outward pulling force on the limiting plate 3, thereby disengaging from the angle adjustment disc 4 and releasing the locking state.

[0033] Reducing the thickness of the connection between the limiting plate 3 and the fixed bracket 1 reduces the resistance to the rotation of the limiting plate 3, making the adjustment of the locking state of the device easier and more convenient.

[0034] like Figure 1 As shown, both the fixed bracket 1 and the adjustable bracket 2 have several mounting holes 11 in the middle. The fixed bracket 1 is fixedly connected to the desktop or wall through the mounting holes 11, and the adjustable bracket 2 is fixedly connected to the monitor through the mounting holes 11.

[0035] The working principle of this utility model is as follows:

[0036] S1. Connect the bolts to the mounting holes 11 on the fixed bracket 1, and install the bracket on the wall or table.

[0037] S2. Connect the bolts to the mounting holes 11 on the adjustment bracket 2 and install the monitor on the adjustment bracket 2.

[0038] S3. When it is necessary to lock the angle of the adjusting bracket 2, rotate the wing nut 10. The screw 7 moves outward under the action of the thread engagement of the wing nut 10, and at the same time pulls the limiting plate 3 to rotate inward and outward and engage with the serrations on the angle adjusting disc 4, thereby locking the angle of the adjusting bracket 2.

[0039] S4. When the angle of the adjusting bracket 2 needs to be adjusted, the wing nut 10 is rotated in the opposite direction so that the screw 7 no longer pulls the limiting plate 3 outward. Under the action of its own elasticity, the limiting plate 3 tilts inward and is offset from the angle adjusting disc 4. The angle adjusting disc 4 is no longer locked, so the angle can be adjusted. The angle can be adjusted and locked by rotating the wing nut 10. The operation is convenient and the structure is simple.
