Description

Technical Field

[0001] This utility model relates to the field of monitor stand technology, and more specifically, to an adjustable-angle monitor stand for teaching. Background Technology

[0002] In multimedia teaching scenarios, monitor stands are crucial for connecting teaching equipment with teachers and students. Their stability, angle adjustment flexibility, and spatial adaptability directly impact teaching efficiency. With the increasing popularity of interactive teaching and group presentations, teachers need to frequently adjust monitor angles to accommodate the viewing needs of students in different positions. Simultaneously, sufficient space must be reserved on the desktop for lesson plans, chalk, teaching aids, and other items. Traditional monitor stands for teaching are gradually revealing numerous significant drawbacks and failing to meet the diverse needs of modern teaching.

[0003] First, the conflict between stability and angle adjustment is prominent. Traditional monitor stands mostly use a fixed support structure with a limited range of angle adjustment, allowing only small tilt adjustments, which cannot meet the needs of teachers to present to students in different areas. Some stands that can achieve large-angle adjustments have a fixed support area, causing the monitor's center of gravity to shift after adjustment, making them prone to wobbling or even tipping over, especially when placing large monitors, where the stability problem is more serious. To improve stability, some stands use an enlarged base design, but an excessively large base takes up a lot of desktop space, leaving no place to put lesson plans and teaching aids, which in turn affects the convenience of teaching operations, creating a dilemma of "stability versus space".

[0004] Secondly, they lack spatial adaptability and are inconvenient to store. Traditional stands often have an integrated support structure that remains fixed regardless of use, occupying significant desk space even when not in use. This is especially problematic in multimedia classrooms where temporary activities or desk cleanup are needed, as the fixed structure becomes an obstacle. Some foldable stands are cumbersome to fold, requiring the disassembly of multiple parts, and still have many protruding structures after folding, making them difficult to move and store. In demanding teaching environments, teachers often lack the time to manage stand storage, resulting in cluttered desks and negatively impacting the cleanliness of the teaching environment and teaching efficiency.

[0005] Therefore, an adjustable-angle monitor stand for teaching is proposed to address the above problems. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] To address the problems existing in the prior art, the purpose of this utility model is to provide an adjustable-angle teaching monitor stand. The monitor stand in this solution has two forms: the support plate can be reliably attached to save space, and after unfolding, it is positioned and stabilized by the limiting rod assembly; the angle adjustment assembly enables flexible adjustment in both horizontal and vertical directions. It has the advantages of dual-state support, convenient adjustment, and strong spatial adaptability, making it suitable for various teaching scenarios and improving teaching display efficiency.

[0008] 2. Technical Solution

[0009] To solve the above problems, the present invention adopts the following technical solution.

[0010] An adjustable-angle monitor stand for teaching includes a base, an angle adjustment component fixedly connected to the upper end of the base, a display mounting plate mounted on the top of the angle adjustment component, support plates on both sides of the base, a pair of support plates arranged symmetrically, a limit rod assembly on the top of the support plate, and a limit block fixedly connected to the top of the base, the limit block having a pair of limit holes matching the limit rod assembly.

[0011] Furthermore, the limiting rod assembly includes a front rod and a rear rod. The front rod is fixedly connected to the support plate, and a screw is fixedly connected to one end of the rear rod. The front rod has a screw hole that matches the screw.

[0012] Furthermore, a pair of the limiting rod assemblies respectively pass through a pair of the limiting holes, and the pair of limiting rod assemblies are arranged in an alternating manner.

[0013] Furthermore, a first magnet is installed at both ends of the base, and a second magnet matching the first magnet is installed at the end of the support plate near the first magnet.

[0014] Furthermore, the angle adjustment assembly includes a vertical rotating seat fixedly installed on the upper end of the base, a vertically arranged support rod rotatably installed on the upper end of the vertical rotating seat, a horizontally arranged rotating seat fixedly installed on the upper end of the support rod, and a display screen mounting plate rotatably installed on the front end of the horizontal rotating seat.

[0015] Furthermore, anti-slip pads are installed at the bottom ends of both the base and the pair of support plates.

[0016] 3. Beneficial Effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] (1) This device solves the problem by using a dual-state support of "adsorption and convergence - limit and unfold": When the support plate is brought together, the first magnet and the second magnet are attracted and fixed, and the anti-slip pad ensures stability when used at a small angle; before large angle adjustment, the support plate is unfolded and positioned by the limit rod assembly through the limit block. The staggered limit rods form a stable lateral support to counteract the center of gravity offset force. At the same time, the anti-slip pad enhances the friction of the desktop. Whether the angle is small or large, the display can be kept stable without shaking, which can adapt to different teaching and display needs.

[0019] (2) This device achieves efficient space utilization through an adjustable structure: when in normal use and the angle does not need to be adjusted significantly, the support plate is close to the base, the overall space occupied is small, and the table can be used to place teaching materials and teaching aids; when adjusting to a large angle, the support plate is unfolded to obtain stable support, and it can be quickly closed and reset after use; if the table needs to be thoroughly cleaned, the rear rod of the limit rod assembly can be unscrewed to further reduce space occupation.

[0020] (3) The device is a fully mechanical structure that enables tool-free and rapid operation: When adjusting the angle, the display can be rotated and positioned by pushing it horizontally through the vertical rotating seat, and the display can be suspended by the damping shaft of the horizontal rotating seat by bending it vertically, without any tools; the expansion and retraction of the support plate only requires overcoming the magnetic attraction force, and the length adjustment and disassembly of the limit rod assembly can be completed by manually turning the screw. The operation process is simple and intuitive, and teachers can make adjustments in real time during the teaching process without interrupting the teaching rhythm, thereby improving teaching efficiency and interactive experience.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Example:

[0032] Please see Figures 1-5 An adjustable-angle monitor stand for teaching includes a base 1, an angle adjustment component fixedly connected to the upper end of the base 1, a display mounting plate 4 installed on the top of the angle adjustment component, support plates 2 on both sides of the base 1, a pair of support plates 2 arranged symmetrically, a limit rod assembly 6 provided on the top of the support plate 2, and a limit block 5 fixedly connected to the top of the base 1, with a pair of limit holes on the limit block 5 that match the limit rod assembly 6.

[0033] In this solution, a pair of support plates 2 are normally attached to both ends of the base 1. The monitor can be mounted on the top of the bracket 3 via the display mounting plate 4. The connection method between the display mounting plate 4 and the monitor is existing technology and will not be elaborated here. One end of the pair of support plates 2 extends to the front of the display mounting plate 4. When the monitor is mounted on the display mounting plate 4, the pair of support plates 2, together with the base 1, can provide stable support for the monitor, ensuring that the monitor will not tip over. Moreover, the pair of support plates 2 are concentrated on the lower side of the monitor and will not occupy a large amount of desktop space.

[0034] When teaching, it is necessary to adjust different angles to display content. However, adjusting the screen angle will cause the center of gravity to shift, which will reduce the overall stability of the stand. Therefore, the support plate 2 can be adjusted to extend outward to increase the support area and ensure stability after the angle is adjusted.

[0035] Please see Figure 3-4 The limiting rod assembly 6 includes a front rod 601 and a rear rod 602. The front rod 601 is fixedly connected to the support plate 2. One end of the rear rod 602 is fixedly connected to a screw 603. The front rod 601 has a screw hole that matches the screw 603. A pair of limiting rod assemblies 6 pass through a pair of limiting holes, and the pair of limiting rod assemblies 6 are arranged in an alternating manner.

[0036] In summary, the monitor stand in this solution has two modes. When used at a normal angle, the user can bring the pair of support plates 2 together on both sides of the base 1 to save desktop space and place some teaching materials. When the screen needs to be adjusted at an angle, and the adjustment range is large enough to cause instability, the user can pull the pair of support plates 2 apart to obtain a larger support area to ensure stability. When the screen is not in use, the pair of rear rods 602 extend to the outside of the pair of support plates 2, which will also occupy some desktop space and may cause inconvenience to the user. When the pair of support plates 2 can be pulled apart, the rear rods 602 can be rotated to drive the screws 603 to rotate in the screw holes of the front rods 601, thereby removing the rear rods 602 from the front rods 601 and saving the desktop space occupied by the rear rods 602.

[0037] The base 1 has a first magnet 8 installed at both ends, and the support plate 2 has a second magnet 7 that matches the first magnet 8 installed at the end near the first magnet 8.

[0038] In this design, the second magnet 7 and the first magnet 8 that are close to it are attracted to each other by opposite polarities. Therefore, when a pair of support plates 2 abut against the two sides of the base 1, the second magnet 7 and the first magnet 8 that are in contact with each other will attract each other, thereby attracting the pair of support plates 2 to the two sides of the base 1, improving the stability of the pair of support plates 2 when they abut against the two ends of the base 1, so that they will not easily move relative to the base 1.

[0039] The angle adjustment assembly includes a vertical rotating seat 9 fixedly installed on the upper end of the base 1, a vertically arranged support rod 3 rotatably installed on the upper end of the vertical rotating seat 9, a horizontally arranged rotating seat 10 fixedly installed on the upper end of the support rod 3, and a display screen mounting plate 4 rotatably installed on the front end of the horizontal rotating seat 10.

[0040] The support rod 3 can be adjusted horizontally on the vertical rotating seat 9, and the display screen mounting plate 4 can be adjusted vertically on the horizontal rotating seat 10.

[0041] The vertical rotating base 9 is fixedly installed on the upper end of the base 1. It is made of stainless steel and has a deep groove ball bearing embedded inside. The inner ring of the bearing is fixed to the lower end of the support rod 3, ensuring that the support rod can rotate smoothly around the vertical axis, realizing 360° horizontal angle adjustment of the monitor. A dust cover is provided on the outside of the bearing to prevent chalk dust and other teaching dust from entering and affecting the smoothness of rotation. The support rod 3 is an aluminum alloy round tube structure, which is lightweight and has a strong load-bearing capacity. Its upper end is welded and fixed to the horizontal rotating base 10. The horizontal rotating base 10 is made of stainless steel and uses a damping shaft to connect to the display mounting plate 4, which can support the monitor to be suspended at any vertical angle and avoid sudden angle changes during adjustment. The display mounting plate 4 is made of cold-rolled steel plate or aluminum alloy plate, with multiple sets of mounting holes on the surface to accommodate wall-mounting screw holes for monitors of different sizes. The edges of the plate are rounded to prevent hand injuries during installation.

[0042] Anti-slip pads are installed at the bottom of both the base 1 and the pair of support plates 2.

[0043] The anti-slip pads on the bottom of the base 1 and support plate 2 can effectively enhance the friction between the base 1 and support plate 2 and the desktop, thereby improving the stability of the monitor when it is placed.

[0044] Working principle:

[0045] Step 1, Initial Storage State: The monitor is fixed to the display mounting plate 4 with screws. At this time, a pair of support plates 2 are close to both sides of the base 1. The second magnet 7 at the end of the support plate and the first magnet 8 at both ends of the base attract each other, firmly adhering the support plate and preventing it from shaking. In the limiting rod assembly 6, the rear rod 602 is connected to the front rod 601 by screws 603, and the whole assembly is stored inside the support plate. The pair of limiting rod assemblies are not inserted into the limiting holes of the limiting block 5. The bracket occupies little desktop space. The anti-slip pads at the bottom of the base and support plate are close to the desktop, ensuring the stability of the monitor when it is stationary. Teaching materials such as lesson plans and chalk can be placed normally on the desktop.

[0046] The second step is the preparation for positioning: When adjusting the monitor angle, especially large-angle adjustments that may cause a shift in the center of gravity, the user holds the outer ends of the pair of support plates 2 with both hands and applies outward pulling force to overcome the attraction force of the first magnet 8 and the second magnet 7, thus unfolding the support plates to both sides. During the unfolding process, the limiting rod assembly 6 is pushed simultaneously, so that the entire assembly of the front rod 601 and the rear rod 602 passes through the corresponding limiting holes on the limiting block 5. At this time, the staggered limiting rod assembly forms a "lateral support," restricting the support plates from further unfolding or retracting inward. If it is necessary to further increase the support area, the total length of the rear rod 602 and the front rod 601 can be adjusted by rotating the rear rod 602. After adjustment, the screw 603 tightly engages with the screw hole of the front rod to fix the length, ensuring the stability of the unfolded state of the support plate and providing a solid foundation for angle adjustment.

[0047] The third step is multi-dimensional angle adjustment: After the support plate is positioned, the user can adjust the monitor angle according to the teaching display needs. For horizontal adjustment, push the monitor to rotate the support rod 3 around the bearing inside the vertical rotating seat 9 until the monitor is aligned with the target direction, such as students on the left or right side of the classroom. The smoothness of the bearing ensures a smooth adjustment process, allowing for 360° positioning in any direction. For vertical adjustment, simply turn the monitor; the display mounting plate 4 rotates around the damping axis of the horizontal rotating seat 10, adjusting the monitor's tilt angle, such as tilting forward to display notes or tilting backward to accommodate standing teaching. The damping force ensures the monitor can hover at any vertical angle without the need for an additional locking structure, making adjustment convenient and efficient, meeting the content display needs of different teaching scenarios.

[0048] Step 4, Post-Use Storage: After the lesson, first return the monitor angle to its initial position. If you need to keep the stand on the desktop, push the support plate 2 in the opposite direction to disengage the limiting rod assembly 6 from the limiting hole of the limiting block 5 until the second magnet 7 and the first magnet 8 re-attach, and the support plate returns to a state of close contact with the base. If the desktop needs to be completely cleaned, rotate the rear rod 602 to unscrew the screw 603 from the screw hole of the front rod 601, remove the rear rod, leaving only the front rod connected to the support plate, further saving desktop space, avoiding the rear rod occupying extra space, and facilitating the overall storage or movement of the stand.
