Description

Technical Field

[0001] This utility model relates to the field of multimedia display device structure technology, and in particular to a multi-faceted display device for teaching multimedia presentation. Background Technology

[0002] Multimedia display devices are devices that integrate multiple media information display functions. They are touch screen displays with multimedia information processing capabilities, capable of comprehensively processing various media information such as text, graphics, images, sound, animation, and video to achieve rich display effects. In public places such as shopping malls, museums, and libraries, multimedia display devices are used for information dissemination, exhibitions, and other purposes. In summary, multimedia display devices, with their rich functions, high-definition image quality, and wide range of application scenarios, are playing an increasingly important role in modern society.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, a multi-faceted display device for teaching multimedia presentations includes a support frame 1. A lifting mechanism 2 is fixedly installed on the upper end of the support frame 1. A first multimedia display screen 3, a second multimedia display screen 4, and a third multimedia display screen 5 are movably installed between the lifting mechanisms 2. A base plate 6 is fixedly installed at the lower end of the front and rear surfaces of the support frame 1. There are four base plates 6. A triangular plate 7 is fixedly connected between the base plate 6 and the support frame 1. A universal caster 8 is fixedly installed on the lower surface of the base plate 6 away from the support frame 1. The second multimedia display screen 4 is located in front of the first multimedia display screen 3, and the third multimedia display screen 5 is located behind the first multimedia display screen 3. The triangular plate 7 makes the support frame 1 more stable. The multi-faceted display device can be pushed by the universal caster 8. The lifting mechanism 2 can automatically drive the second multimedia display screen 4 to rise and the third multimedia display screen 5 to fall, and control the unfolding and folding of the first multimedia display screen 3, the second multimedia display screen 4, and the third multimedia display screen 5. This allows the multi-faceted display device to display more teaching information and pictures without frequently switching the multimedia display screens, which is beneficial to the teacher's teaching.

[0021] In this embodiment, the lifting mechanism 2 includes an I-beam frame 201, a first screw 202, a second screw 203, a first motor 204, a second motor 205, a first right-angle frame sleeve 206, a second right-angle frame sleeve 207, a first limiting slide rod 208, and a second limiting slide rod 209.

[0022] In this embodiment, the I-beam frame 201 is fixedly installed on the side of the No. 1 multimedia display screen 3, and the lower end of the I-beam frame 201 is fixedly connected to the upper end of the support frame 1.

[0023] In this embodiment, both ends of screw 202 and screw 203 are inserted into the limiting through holes at both ends of the I-beam frame 201.

[0024] In this embodiment, motor 204 is fixedly installed on the upper surface of I-beam frame 201, motor 205 is fixedly installed on the lower surface of I-beam frame 201, the rotating shaft of motor 204 is fixedly connected to the upper end of screw 202, and the rotating shaft of motor 205 is fixedly connected to the lower end of screw 203.

[0025] In this embodiment, a first right-angle frame sleeve 206 is fitted onto the outside of a first screw 202, and a first limiting slide rod 208 is fixedly installed on the side of a third multimedia display screen 5. The first right-angle frame sleeve 206 is fixedly connected to the two upper corners of the third multimedia display screen 5. The lower end of the first limiting slide rod 208 passes through the limiting groove at the lower end of the I-beam frame 201. When the third multimedia display screen 5 is to be lowered, a first motor 204 drives the first screw 202 to rotate, causing the first right-angle frame sleeve 206 to rise and fall along the first screw 202. The first limiting slide rod 208 slides in the limiting groove at the lower end of the I-beam frame 201, and the height of the third multimedia display screen 5 decreases accordingly. The first limiting slide rod 208 makes the raising and lowering of the third multimedia display screen 5 more stable.

[0026] In this embodiment, the second right-angle frame sleeve 207 is fitted onto the outside of the second screw 203, and the second limiting slide rod 209 is fixedly installed on the side of the second multimedia display screen 4. The second right-angle frame sleeve 207 is fixedly connected to the two lower corners of the second multimedia display screen 4. The upper end of the second limiting slide rod 209 passes through the limiting groove at the upper end of the I-beam frame 201. When the second multimedia display screen 4 rises, the second motor 205 drives the second screw 203 to rotate, and the second right-angle frame sleeve 207 moves up and down outside the second screw 203. The upper end of the second limiting slide rod 209 slides in the limiting groove at the upper end of the I-beam frame 201, and the second multimedia display screen 4 rises accordingly. The second limiting slide rod 209 makes the rise and fall of the second multimedia display screen 4 more stable.
