Description

Technical Field

[0001] This utility model relates to the field of multimedia exhibition stand technology, specifically to an adjustable multimedia exhibition stand for 3D display. Background Technology

[0002] A multimedia display stand, also known as a document camera or video display stand, is a device that clearly displays materials, objects, slides, etc. By connecting to output devices such as projectors, televisions, and monitors, the items on the display stand can be presented to the audience in the form of images. It is widely used in teaching, conferences, business presentations, and other occasions. 3D multimedia display, on the other hand, is a display method that combines three-dimensional models with multimedia elements. By utilizing advanced technology, it brings a more intuitive, vivid, and immersive experience to the audience.

[0003] Currently, multimedia exhibition stands on the market come in a variety of models and styles, capable of adjusting the height, angle, and even number of display screens. Among these, to meet the demands of 3D multimedia displays, there exists a type of 3D multimedia exhibition stand that can use multiple displays to present the same object in 3D from multiple angles without a physical object. This achieves a direct and comprehensive display effect while saving on material costs, significantly improving the display effect for items with complex parts, such as mechanical equipment. However, this solution often requires fixing the number and position of the display screens in advance during assembly, making it difficult to adjust the positions of multiple screens simultaneously. This leads to inconvenience during use and reduces the versatility of the exhibition stand's working states and the overall display effect. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable multimedia exhibition stand for 3D display, which can simultaneously adjust the position of multiple display screens, thereby enhancing the diversity of the exhibition stand's working states and the display effect.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An adjustable multimedia display stand for 3D display is provided, including a frame, multiple mounting frames, a pair of turntables, and a synchronous flipping component. One side of the mounting frame is fixedly connected to a display screen. The frame includes a base, the top of which is attached to the bottom of the mounting frame. The multiple mounting frames are arranged in a circle on the top of the base. One mounting frame is fixedly installed on one side of the top of the base, and the other two mounting frames are fixedly installed on the tops of the two turntables respectively. The two turntables are symmetrically distributed on both sides of the top of the base. The turntables pass through the top wall of the base and are rotatably connected to it. The synchronous flipping component is installed on the base and is used to drive the turntables to rotate.

[0007] Furthermore, a bracket is fixedly connected to the other side of the mounting frame. One of the brackets has a support rod fixedly connected to its bottom, and the bottom of the support rod is fixedly connected to one side of the top of the base. The bottoms of the other two brackets have diagonal rods fixedly connected to their bottoms, and the bottoms of the diagonal rods are fixedly connected to the eccentric part of the top of the turntable.

[0008] Furthermore, the synchronous flipping assembly includes a hydraulic rod, a U-shaped rod, a pair of transmission mechanisms, and a pair of locking mechanisms. One end of the hydraulic rod is fixedly connected to the inner wall of the base, the telescopic end of the hydraulic rod is fixedly connected to one end of the U-shaped rod, and the bottom of the U-shaped rod is slidably connected to the bottom wall of the base. The transmission mechanism is mounted on the turntable and is used to convert the horizontal driving force of the hydraulic rod into a rotational driving force. The locking mechanism is mounted on the base and is used to lock the mounting frame.

[0009] Furthermore, the transmission mechanism includes a rotating shaft, gears, racks, and a sliding plate. The sliding plate is horizontally mounted on a U-shaped rod, and the other end of the sliding plate is fixedly connected to the rack. The rack and gear mesh with each other, the gears are coaxially connected to the outer periphery of the rotating shaft, the rotating shaft is rotatably connected to the bottom wall of the base, and the top of the rotating shaft is coaxially connected to the bottom of the turntable.

[0010] Furthermore, the transmission mechanism also includes a telescopic rod, a spring, and a limiting strip. The bottom of the limiting strip is fixedly connected to the bottom wall of the base, and the limiting strip is slidably connected to the bottom of the slide plate. One end of the slide plate passes through the side wall of the U-shaped rod and is slidably connected to it. One end of the telescopic rod is fixedly connected to the U-shaped rod, and the telescopic end of the telescopic rod is fixedly connected to the slide plate. The spring is sleeved around the telescopic rod, and both ends of the spring are fixedly connected to the U-shaped rod and the slide plate, respectively. When the slide plate abuts against the inner wall of one side of the limiting strip, the multiple displays form a triangular prism structure. When the slide plate abuts against the inner wall of the other side of the limiting strip, the multiple displays form a fan-shaped folded structure.

[0011] Furthermore, the locking mechanism includes a limiting rod, a plug rod, and a plug block. The plug block is fixedly connected to the bottom of one side of the mounting frame. The top of the plug rod is inserted into the inner wall of the plug block. A pair of grooves are provided on the top of the U-shaped rod.

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0032] Reference Figures 1 to 8 The adjustable multimedia display stand for 3D display includes a frame 1, multiple mounting frames 2, a pair of turntables 23, and a synchronous flipping component 3. One side of the mounting frame 2 is fixedly connected to the display screen 24. The frame 1 includes a base 10, the top of the base 10 and the bottom of the mounting frame 2 are attached to each other. Multiple mounting frames 2 are arranged in a circle on the top of the base 10. One mounting frame 2 is fixedly installed on one side of the top of the base 10, and the other two mounting frames 2 are fixedly installed on the top of the two turntables 23 respectively. The two turntables 23 are symmetrically distributed on both sides of the top of the base 10. The turntables 23 pass through the top wall of the base 10 and are rotatably connected to it. The synchronous flipping component 3 is installed on the base 10 and is used to drive the turntables 23 to rotate.

[0033] The display screens 24 are fixedly connected to the mounting frames 2 with bolts, thereby arranging multiple display screens 24 in a circular pattern on the top of the base 10. The mounting frames 2 fit together to form a triangular prism structure, allowing for 3D display through the display screens 24, showcasing the model from 360 degrees. Subsequently, the synchronous flipping component 3 drives the two turntables 23 to rotate, simultaneously flipping the two mounting frames 2 on top of the turntables 23 180 degrees in the opposite direction. This causes the multiple display screens 24 to form a fan-shaped folded structure, which can semi-enclose visitors within the fan shape and extend the length of the display screens 24, thereby enhancing the display effect. It also has the ability to switch between multiple display states, expanding the applicability of the booth.

[0034] like Figures 3 to 6 As shown, a bracket 20 is fixedly connected to the other side of the mounting frame 2. One of the brackets 20 has a support rod 21 fixedly connected to its bottom. The bottom of the support rod 21 is fixedly connected to one side of the top of the base 10. The bottoms of the other two brackets 20 have diagonal rods 22 fixedly connected to their bottoms. The bottoms of the diagonal rods 22 are fixedly connected to the eccentric part of the top of the turntable 23.

[0035] The mounting frame 2 at the top of the base 10 is supported by the bracket 20 and the support rod 21, so that it is fixedly installed on the top of the base 10. The mounting frame 2 at the top of the turntable 23 is supported by the bracket 20 and the diagonal rod 22, and the bottom of the diagonal rod 22 is fixedly connected to the eccentric part of the top of the turntable 23. This allows the mounting frame 2 to not only follow the rotation direction of the turntable 23, but also to keep multiple mounting frames 2 in close contact, thereby eliminating visual gaps and improving the display effect.

[0036] like Figures 5 to 8 As shown, the synchronous flipping assembly 3 includes a hydraulic rod 30, a U-shaped rod 31, a pair of transmission mechanisms 4, and a pair of locking mechanisms 5. One end of the hydraulic rod 30 is fixedly connected to the inner wall of the base 10, and the telescopic end of the hydraulic rod 30 is fixedly connected to one end of the U-shaped rod 31. The bottom of the U-shaped rod 31 is slidably connected to the bottom wall of the base 10. The transmission mechanism 4 is mounted on the turntable 23 and is used to convert the horizontal driving force of the hydraulic rod 30 into a rotational driving force. The locking mechanism 5 is mounted on the base 10 and is used to lock the mounting frame 2.

[0037] The transmission mechanism 4 includes a rotating shaft 40, a gear 41, a rack 42, and a slide plate 43. The slide plate 43 is horizontally movable and mounted on the U-shaped rod 31. The other end of the slide plate 43 is fixedly connected to the rack 42. The rack 42 and the gear 41 mesh with each other. The gear 41 is coaxially connected to the outer periphery of the rotating shaft 40. The rotating shaft 40 is rotatably connected to the bottom wall of the base 10. The top of the rotating shaft 40 is coaxially connected to the bottom of the turntable 23.

[0038] The transmission mechanism 4 also includes a telescopic rod 44, a spring 45, and a limiting strip 46. The bottom of the limiting strip 46 is fixedly connected to the bottom wall of the base 10, and the limiting strip 46 is slidably connected to the bottom of the slide plate 43. One end of the slide plate 43 passes through the side wall of the U-shaped rod 31 and is slidably connected to it. One end of the telescopic rod 44 is fixedly connected to the U-shaped rod 31, and the telescopic end of the telescopic rod 44 is fixedly connected to the slide plate 43. The spring 45 is sleeved around the telescopic rod 44, and both ends of the spring 45 are fixedly connected to the U-shaped rod 31 and the slide plate 43, respectively. When the slide plate 43 abuts against the inner wall of one side of the limiting strip 46, the multiple displays 24 form a triangular prism structure. When the slide plate 43 abuts against the inner wall of the other side of the limiting strip 46, the multiple displays 24 form a fan-shaped folded structure.

[0039] The hydraulic rod 30 is activated, its telescopic end extends, pushing the U-shaped rod 31 to slide horizontally. At this time, the spring 45 rebounds from the compressed state, the telescopic rod 44 extends and keeps the deformation direction of the spring 45 unchanged, so that the slide plate 43 remains stationary, with one end sliding inside the U-shaped rod 31, and the locking mechanism 5 unlocks. Subsequently, the U-shaped rod 31 continues to move, and its inner wall presses against the slide plate 43, causing the slide plate 43 to slide horizontally along the limit strip 46 inside the base 10. The slide plate 43 drives the rack 42 to move, and through the meshing transmission between the rack 42 and the gear 41, the horizontal thrust of the hydraulic rod 30 is converted into rotational force around the rotating shaft 40, thereby causing the turntable 23 to drive the mounting frame 2 to rotate. The two transmission mechanisms 4 are symmetrically arranged on both sides of the U-shaped rod 31, so that the two turntables 23 rotate in opposite directions, thereby enabling the two displays 24 on the top to rotate 180 degrees relative to each other, so that the multiple displays 24 are adjusted from a triangular prism structure to a fan-shaped folded structure. Similarly, when the telescopic end of the hydraulic rod 30 moves in the opposite direction, it can drive the mounting frame 2 to reset. After the slide plate 43 moves to abut against the inner wall of the limit strip 46, it can also lock the mounting frame 2 as the U-shaped rod 31 continues to slide.

[0040] like Figures 3 to 8 As shown, the locking mechanism 5 includes a limiting rod 50, a plug rod 51, and a plug block 52. The plug block 52 is fixedly connected to the bottom of one side of the mounting frame 2. The top of the plug rod 51 is inserted into the inner wall of the plug block 52. A pair of grooves 310 are provided on the top of the U-shaped rod 31. The inner wall of one side of the groove 310 is a sloping structure. The bottom of the plug block 52 passes through the top wall of the base 10 and abuts against the inner wall of the groove 310. The limiting rod 50 is fixedly connected to the inner wall of the base 10. The limiting rod 50 passes through the plug rod 51 and is slidably connected to it.

[0041] When multiple displays 24 have a triangular prism structure, the top of the limiting rod 50 is inserted into the insert block 52, and the bottom passes through the top wall of the base 10 and abuts against the top of the U-shaped rod 31, thereby locking the free end of the mounting frame 2 and preventing it from moving, thus ensuring the stability of the triangular prism structure. When the U-shaped rod 31 moves, the insert rod 51 slides into the groove 310 under the action of gravity, and its top disengages from the insert block 52, thereby unlocking the mounting frame 2 and allowing the display direction to be adjusted. The limiting rod 50 passes through the insert rod 51 to prevent the insert rod 51 from slipping out.

[0042] like Figures 1 to 4 As shown, it also includes a base 13 and a motor 14. The top of the base 13 is rotatably connected to the base 10, the top of the motor 14 is fixedly connected to the top wall of the base 13, and the output shaft of the motor 14 passes through the top wall of the base 13 and is coaxially connected to the base 10.

[0043] The platform 1 also includes a support column 11 and a canopy 12. The bottom of the support column 11 is coaxially connected to the top of the base 10, the top of the support column 11 is coaxially connected to the bottom of the canopy 12, and the bottom of the canopy 12 is in close contact with the top of the mounting frame 2.

[0044] The canopy 12 is supported by the support column 11 and is located above and in contact with the mounting frame 2, serving to cover the open space at the top and provide protection. When the multiple displays 24 are triangular prism structures, the motor 14 is powered on and its output shaft drives the base 10 to rotate on the platform 13, which enables the multiple displays 24 to rotate slowly. Combined with 3D display technology, the structural composition and component positions can be displayed in a comprehensive and intuitive manner without the need for visitors to move around, further improving the display effect.

[0045] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
