See also Figures 1 to 9 The present invention provides a business administration teaching information display device, which can be used to improve the problems of poor flexibility and inconvenient adjustment of traditional display equipment and meet the needs of various teaching scenarios.

[0021] Specifically, the business administration teaching information display device disclosed in the present invention includes a base 100 , a first connecting rod 120 , a second connecting rod 130 , an elastic rod 150 , a connecting block 200 and a supporting cross bar 300 .

[0022] The base 100 has a disc-shaped structure, with an annular mounting groove 101 provided on the periphery, and at least three sets of connecting shafts 102 are symmetrically arranged in the center of the groove for connecting the support rod 110. The base 100 is made of aluminum alloy, which is lightweight and highly stable. The support rod 110 is unidirectionally connected to the connecting shaft 102 through an articulated seat 103 and an articulated rod 104, and a multi-directional roller 111 is installed at the end of the support rod 110 for easy movement and positioning. For example, the multi-directional roller 111 can be a φ80mm polyurethane wheel with a brake function.

[0023] Specifically, the connecting shaft 102 is rotatably connected to a hinge seat 103, and the other end of the hinge seat 103 is rotatably connected to a hinge rod 104. One end of the support rod 110 is unidirectionally rotatably connected to the hinge rod 104. The angle of the support rod 110 can be independently adjusted (0°-90°) to adapt to different ground environments.

[0024] Furthermore, the first connecting rod 120 is vertically fixed to the center of the base 100, and a scale mark is set on the surface for reference of height adjustment. The second connecting rod 130 is slidably connected to the first connecting rod 120 through a slide rail, can be raised and lowered in the vertical direction, and is fixed in position by a locking structure such as a bolt or a buckle. A long strip notch 140 is symmetrically provided at the top of the second connecting rod 130 for accommodating the undeployed support cross bar 300.

[0025] Furthermore, one end of the elastic rod 150 is hinged to the top of the second connecting rod 130, and the other end is connected to the bracket 160 through a universal joint, so that the tilt angle of the bracket 160 can be adaptively adjusted. The connecting block 200 is hinged to the end of the bracket 160, and is provided with a first connecting groove 201, a second connecting groove 202 and a third connecting groove 203, wherein the second and third connecting grooves 203 are symmetrically arranged and have a built-in rotating shaft 204. A first connecting surface 210 and a second connecting surface 220 are provided on the connecting block 200, and the two planes are vertically distributed to adapt to the single / dual screen deployment mode.

[0026] Specifically, one end of the support crossbar 300 is fixed on the rotating shaft 204, and can rotate horizontally (0°-180°) around the rotating shaft 204, and is locked in a horizontal state by a limiting structure. For example, the limiting structure can be a ratchet lock.

[0027] A T-shaped slot 310 is provided below the support crossbar 300, and a plurality of clamping blocks 320 are slidably connected in the slot. The clamping blocks 320 are equipped with spring clips and magnetic sheets for fixing the curtain 400 or a light electronic screen. In addition, a magnetic strip is provided in the slot to absorb the clamping blocks 320.

[0028] Specifically, in actual use, the device includes at least a single-screen mode, a dual-screen mode, and a horizontal screen mode.

[0029] The single-screen mode refers to unfolding a single supporting crossbar 300, with the connecting block 200 attached to the first connecting surface 210, and the other crossbar received in the slot 140, which is suitable for conventional projection or writing.

[0030] The double screen mode refers to unfolding the double supporting cross bars 300, and the connecting block 200 is attached to the first connecting surface 210. At the same time, each supporting cross bar 300 can be connected with a curtain 400 or a light electronic screen.

[0031] The horizontal screen mode refers to unfolding the double supporting cross bars 300, the connecting block 200 is attached to the second connecting surface 220, and the two cross bars are horizontally symmetrically distributed. At this time, the screen 400 is horizontally connected to the two supporting cross bars 300, which can be suitable for comparative analysis or simultaneous display of multiple contents.

[0032] Furthermore, in order to improve the use effect of the device in actual use, an anti-skid pad can be added to the bottom of the base 100, and the support rod 110 forms a triangular support structure after being unfolded. At the same time, a damper is built into the elastic rod 150 to prevent the bracket 160 from shaking due to external force.

[0033] Furthermore, the clamping block 320 can be equipped with a touch screen or a wireless projection module to support screen projection interaction of student terminals. And the bracket 160 has a reserved USB / HDMI interface to achieve quick connection of peripherals.

[0034] The present invention also provides a method for using any of the above-mentioned business administration teaching information display devices.

[0035] Specifically, it includes at least the following steps.

[0036] Step 1: Adjust the angles between adjacent support rods 110 to adapt to the display environment.

[0037] By unfolding the support rod 110 to the target angle (recommended 60°-75°), the position is locked by the hinge rod 104. The multi-directional roller 111 is pushed to move the device to the target area, and the anti-skid pad of the base 100 contacts the ground.

[0038] Step 2: Adjust the relative positions of the first connecting rod 120 and the second connecting rod 130 and lock them.

[0039] Slide the second connecting rod 130 to a desired height (adjusted according to the size of the screen 400 or the height of the teacher), and tighten the locking structure.

[0040] Step 3: Select and unfold one or two supporting cross bars 300 according to the environment.

[0041] Specifically, when the single screen mode is adopted, the single support cross bar 300 can be pulled outward to a horizontal position, and the limit structure is automatically locked. The connecting block 200 is attached to the first connecting surface 210, and the other cross bar is stored in the notch 140. When the dual screen mode is adopted, the two support cross bars 300 can be deployed at the same time, and the connecting block 200 is attached to the second connecting surface 220. The clamping block 320 is slid through the slide groove 310 to ensure that the curtain 400 is flat.

[0042] Step 4: Based on the actual use status, adjust the position of the connection block 200 and clamp the curtain 400 on the connection block 200 .

[0043] Specifically, the two sides of the curtain 400 are embedded in the spring clips of the clamping block 320, and the magnetic sheet is adsorbed on the magnetic strip of the slide slot 310 to fix the position. An external electronic device can also be fixed to the bracket 160, and the power supply and signal source are connected through the interface.

[0044] The method may further include step 5: dynamically adjusting the position, which includes rotating the elastic rod 150 to adjust the angle of the bracket 160 to adapt the projection light or the student's viewing angle, and sliding the clamping block 320 to adjust the tension of the screen 400 in real time to prevent wrinkles.

[0045] In summary, the present invention discloses a business administration teaching information display device and a method of use. Through the single / dual screen mode quick switching function, it can flexibly adapt to various scenarios such as classroom teaching, group discussion, case analysis, etc., and meet multi-dimensional teaching needs such as lectures, comparisons, and interactions; thanks to the triangular support structure and the damping elastic rod 150 design, even if a large screen 400 or an electronic display screen is installed, it can still maintain high stability and avoid shaking or tilting problems; its modular magnetic clamping block 320 and slide rail locking structure can further simplify the operation process and realize "one-click" convenient operations such as height adjustment and screen 400 fixing; at the same time, the device takes into account both scalability and compatibility, and can be seamlessly coordinated with traditional projection screens 400 and physical display boards, and can also be integrated with smart devices such as touch screens and wireless projection screens, and an Internet of Things interface is reserved to support subsequent function upgrades (such as remote control and data synchronization), fully adapting to the development trend of educational technology.

[0046] Therefore, it can effectively improve the problems of poor flexibility and inconvenient adjustment of traditional display equipment and meet the needs of various teaching scenarios.
