Description

Technical Field

[0001] This utility model belongs to the technical field of collaborative learning equipment, and in particular relates to a rotatable multi-angle collaborative learning display screen bracket. Background Technology

[0002] With the rapid development of information-based teaching and remote collaborative work, multi-screen display technology has been widely used in education, meetings, and collaborative work scenarios. Especially in collaborative learning environments, two or more learners often need to simultaneously view and operate adjacent displays to achieve information sharing, real-time interaction, and synchronized thinking. However, most of the display stands commonly found on the market are single-screen fixed types or simple structures that only support limited angle adjustment, making it difficult to meet the actual needs of multiple people, multiple viewing angles, and dynamic interaction.

[0003] Traditional stands typically offer only a single degree of freedom, either tilt or swivel. Furthermore, if multiple displays are to be used side-by-side, separate stands are often required, resulting in significant space consumption, messy wiring, and a lack of coordination between screens, hindering flexible configurations for unified or differentiated viewing angles. In addition, while some adjustable stands offer some flexibility, their complex structure, heavy weight, and cumbersome adjustments, coupled with a lack of effective cable management mechanisms, can easily lead to cable strain, loose connections, or even device damage during frequent adjustments. More importantly, existing products generally lack optimization for the specific application scenario of collaborative learning, failing to comprehensively consider the independence of viewing angles and ease of interaction when two or more users are using the device simultaneously.

[0004] To address this issue, we provide a rotatable, multi-angle collaborative learning display stand. Utility Model Content

[0005] The purpose of this invention is to provide a rotatable, multi-angle collaborative learning display stand. By setting an independent double-branch support structure with multiple degrees of rotational freedom, it solves the problems of insufficient adjustment freedom of existing display stands in collaborative learning scenarios and difficulty in independently adapting multiple screen viewing angles.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a rotatable, multi-angle collaborative learning display screen bracket, comprising a bracket body for mounting and adjusting multiple collaborative learning displays; the bracket body includes a vertical rod, the top of which is fitted with a kit via fastening bolts, and an inner support arm rotatably mounted on symmetrically welded lugs on the periphery of the kit via shafts, the inner support arm being rotatably connected to an outer support arm via an adapter, and a back plate being mounted on the outer support arm via a reversing head, the back plate being fixed to the back of the display screen housing; the inner and outer support arms rotate in the same plane, and the reversing head consists of two perpendicularly intersecting bushings, one bushing being rotatably connected to the outer support arm via a shaft, and the other bushing being rotatably connected to the central lug of the back plate via a shaft.

[0007] The present invention is further configured such that a base plate is fixed to the lower part of the vertical rod, and a support plate is fixed to the bottom of the base plate by screws, the base plate and the support plate forming a clamping space, and a screw hole for locking the external screw is opened in the middle position of the support plate.

[0008] The present invention is further configured such that a cable harness sleeve is embedded at the tail of the base plate, and the cable harness connected to the display screen is centrally stored inside the cable harness sleeve.

[0009] The present invention is further configured such that the kit has an open structure, and its opening is fixed by fastening bolts.

[0010] The present invention is further configured such that both the inner and outer support arms are hollow structures, and the middle part of the vertical rod is also hollowed out.

[0011] The present invention is further configured such that the bracket body is adapted to be installed on the back of a pair of displays, and the two branches of the bracket body are independently adjustable.

[0012] The present invention is further configured such that the back plate has a butterfly-shaped structure, and each of the protruding structures of the back plate has positioning holes for bolt installation.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1

[0023] Please see Figure 1-5 This utility model is a rotatable multi-angle collaborative learning display screen bracket, including a bracket body 1 for installing and adjusting multiple collaborative learning displays; the bracket body 1 includes a vertical rod 13, the top of the vertical rod 13 is mounted with a kit 14 by fastening bolts, the kit 14 has symmetrically welded ear seats on its periphery, and an inner support arm 15 is rotatably mounted on it by a shaft; the inner support arm 15 is rotatably connected to an outer support arm 17 by an adapter 16, and the outer support arm 17 is mounted with a back plate 19 by a reversing head 18, the back plate 19 being fixed to the back of the display screen housing; the inner support arm 15 and the outer support arm 17 rotate in the same plane, the reversing head 18 is composed of two vertically intersecting bushings, one bushing is rotatably connected to the outer support arm 17 by a shaft, and the other bushing is rotatably connected to the middle ear seat of the back plate 19 by a shaft.

[0024] The rotatable multi-angle collaborative learning display stand provided in this embodiment aims to achieve flexible, independent, and stable multi-angle adjustment capabilities for multiple displays in collaborative learning scenarios. Its overall structure uses the vertical rod 13 as the central support backbone, and through modular connections and multi-stage rotation mechanisms, it constructs a support system that combines rigid support with degrees of freedom adjustment. The open-type kit 14 at the top of the vertical rod 13 is positioned and locked in the height direction by fastening bolts, and also serves as the mounting base for the upper adjustment mechanism. The ear seats symmetrically arranged on both sides of the kit 14 and the inner support arm 15 form a first-level rotary joint through shafts, allowing the inner support arm 15 to swing in the horizontal plane. The inner support arm 15 then forms a second-level coplanar rotary joint with the outer support arm 17 through the adapter 16, thereby achieving angular extension in the length direction of the support arm. The end of the outer support arm 17 is connected to the back plate 19 through the reversing head 18. The reversing head 18 adopts a double-shaft sleeve structure with mutually perpendicular intersecting shafts, which are hinged to the ear seats in the middle of the outer support arm 17 and the back plate 19, respectively. This introduces the rotational freedom of the third dimension, so that the display screen can not only adjust the orientation in the horizontal plane, but also achieve fine adjustment of the pitch angle and even the tilt posture.

[0025] Specifically, both the inner support arm 15 and the outer support arm 17 are hollow structures, and the middle part of the vertical rod 13 is also hollowed out, which not only reduces the overall weight but also provides space for internal wiring. The bracket body 1 is adapted to be installed on the back of a pair of displays. The two branches of the bracket body 1 are independently adjustable, which can adjust the spatial posture of the displays they support to meet the different needs of multiple people for viewing angle, distance, and orientation when using them together. The back plate 19 has a butterfly-shaped structure, and each of the protruding structures of the back plate 19 has positioning holes for bolt installation, which not only enhances the structural strength but also adapts to display shells of different sizes or models through the positioning holes on multiple protruding parts, thus improving versatility.

[0026] Furthermore, a base plate 11 is fixed to the lower part of the vertical rod 13, and a support plate 12 is fixed to the bottom of the base plate 11 by screws. The base plate 11 and the support plate 12 form a clamping space. A screw hole for locking the external screw is opened in the middle of the support plate 12. A cable bundle sleeve 11a is embedded in the tail of the base plate 11. The cable bundles connected to the display screen are centrally passed through the cable bundle sleeve 11a, which effectively stores and protects the power and signal cables of the display screen, avoids tangling and interference, and improves the neatness and safety of use. The kit 14 has an open structure, and its opening is fixed by fastening bolts.

[0027] The operation process of this embodiment is as follows: First, the entire bracket needs to be fixed to the edge of the desktop or a designated support surface through the clamping space between the base plate 11 and the support plate 12: place the support plate 12 under the desktop and the base plate 11 on top, and tighten it upwards using the external screw passing through the central screw hole of the support plate 12, so that the base plate 11 and the support plate 12 clamp the desktop, completing the stable installation of the bracket body 1; then, the two collaborative learning displays are reliably connected to the positioning holes on the butterfly-shaped back plates 19 on both sides of the bracket through the reserved mounting holes on their backs, using bolts to ensure that the displays are firmly attached to the back plates 19; then, according to the user's height To meet the needs of sitting posture and collaboration, the left and right support arm systems are adjusted independently: First, loosen the fastening bolts at the top of the kit 14 so that the height or initial orientation of the kit 14 can be finely adjusted at the top of the vertical rod 13. Then, operate the adapter 16 between the inner support arm 15 and the outer support arm 17 and the reversing head 18 in sequence so that the inner support arm 15 swings in the horizontal plane to adjust the left and right azimuth angle of the display screen. The outer support arm 17 extends or retracts in the same plane in coordination with the inner support arm 15 to change the distance between the display screen and the user. The reversing head 18, with its vertically intersecting double-axis sleeve structure, allows the back plate 19 to drive the display screen to achieve multi-dimensional posture adjustment of up and down tilt and side tilt. During the adjustment process, all cables (including power cables, video signal cables, etc.) can be led out from the back of the display screen and threaded into the cable bundle 11a located at the tail of the base plate 11. The cables are then routed upwards along the hollow cavity of the vertical rod 13 to maintain a neat appearance and prevent pulling. Ultimately, two or more learners can conduct efficient and comfortable collaborative learning or interactive operations at their optimal viewing distance and angle.
