Description

Technical Field

[0001] This utility model relates to the field of teaching equipment technology, specifically a wall-mounted multimedia all-in-one machine for teaching. Background Technology

[0002] Wall-mounted multimedia all-in-one machines for teaching are high-tech devices that integrate multiple teaching functions, primarily used in modern multimedia classrooms and conference rooms. They are typically wall-mounted and integrate functions such as a computer, projector, and electronic whiteboard, greatly enhancing the convenience and interactivity of teaching and meetings.

[0003] Patent CN210600950U discloses a wall-mounted multimedia all-in-one machine for teaching, which includes a mounting plate, a sliding cover, a body shell, a hanging rod, and a fixing block. A fixing plate is welded to one side wall of the mounting plate, and a fixing groove is opened at the bottom of the fixing plate, and a magnetic plate is fixedly glued thereto. The magnetic plate is magnetically connected to a magnetic block. A support frame is bolted to the side wall of the mounting plate away from the fixing plate. This device ensures the ease of operation of the multimedia all-in-one machine before and after use through the mutual cooperation between the adjustable sliding cover, the body shell, and the mounting plate.

[0004] However, this device uses a sliding cover to open or cover the casing for use. In real-world teaching multimedia devices, dust and impurities easily accumulate on the screen surface due to static electricity. The sliding cover in this all-in-one machine only covers the casing and does not have a cleaning mechanism. If a lot of dust accumulates on the surface for a long time, it will not only affect teaching but also affect the heat dissipation of the device. Therefore, a wall-mounted multimedia all-in-one machine for teaching is proposed to solve the problem that existing multimedia devices cannot clean the surface dust and thus affect teaching.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Please refer to Figure 1-4 A wall-mounted multimedia all-in-one machine for teaching includes a mounting frame 1. One end of the mounting frame 1 is fixedly connected to a base plate 2. The top of the base plate 2 is equipped with a multimedia machine body 3. One end of the mounting frame 1 is equipped with a protective cover 4. One end of the mounting frame 1 has an adjustment groove 5. An adjustment block 6 is slidably arranged in the inner cavity of the adjustment groove 5. A lead screw 7 is rotatably arranged in the inner cavity of the adjustment groove 5. A servo motor 8 is arranged in the top of the mounting frame 1. A dust removal frame 9 is fixedly connected to the bottom of the inner cavity of the protective cover 4. A dust removal scraper 10 is arranged in the inner ring of the dust removal frame 9. The dust removal scraper 10 is hollow inside and has a dust suction hole 11 through the inner ring. A connecting pipe 12 is arranged in the top of the dust removal frame 9. A miniature dust suction pump 13 and a dust collection box 14 are arranged in the top inner wall of the protective cover 4.

[0025] Furthermore, the adjusting block 6 is fixedly connected to the protective cover 4, the lead screw 7 passes through the adjusting block 6 and the two are threadedly connected, and the output shaft of the servo motor 8 is fixedly connected to the lead screw 7.

[0026] Furthermore, during the process of the protective cover 4 moving down to cover the multimedia unit 3, the dust removal scraper 10 and the multimedia unit 3 are in interference fit contact, and the dust removal scraper 10 is set between the upper and lower sets of dust suction holes 11.

[0027] Furthermore, the connecting pipe 12 is interconnected with the inner cavity of the dust removal frame 9, and the miniature dust pump 13 is interconnected with the connecting pipe 12 and the dust collection box 14.

[0028] Furthermore, a groove 15 is provided at one end of the protective cover 4, a writing board 16 is provided in the inner cavity of the groove 15, and two movable plates 17 are symmetrically arranged in the inner cavity of the groove 15, with a second writing board 18 provided at one end of the movable plate 17.

[0029] Furthermore, limiting grooves 19 are provided at the top and bottom of the groove 15. Limiting sliders 20 are slidably connected to the inner cavity of the limiting grooves 19. The limiting sliders 20 are fixedly connected to the moving plate 17. Through the limiting sliders 20 in the limiting grooves 19 in the groove 15, the symmetrically arranged moving plate 17 can be moved out from the groove 15 to both sides, so that writing can be done on the writing board 16 or the second writing board 18 using a writing pen, thereby improving the functionality and practicality of this wall-mounted teaching multimedia all-in-one machine.

[0031] Working Principle: When using this wall-mounted multimedia all-in-one teaching machine, after installing the mounting bracket 1 on the wall at the desired location using bolts and other connecting parts, the servo motor 8 drives the lead screw 7 to rotate. This, in conjunction with the adjusting block 6 in the adjusting slot 5, causes the protective cover 4 to move upwards, exposing the multimedia machine body 3 for teaching. Conversely, the protective cover 4 moves downwards, covering the multimedia machine body 3, thus providing protection. Simultaneously, during the up-and-down movement of the protective cover 4, the dust scraper 10 on the dust removal rack 9 scrapes off dust from the surface of the multimedia machine body 3, and the micro vacuum pump 13 is activated. The connecting pipe 12 creates a negative pressure inside the dust removal rack 9, which in turn draws the dust scraped off by the dust removal scraper 10 into the dust collection box 14 through the dust suction hole 11, thus achieving the purpose of cleaning the dust on the multimedia surface and solving the problem that existing multimedia devices are difficult to clean surface dust, which affects teaching. Through the limiting slider 20 in the limiting groove 19 in the groove 15, the symmetrically arranged movable plate 17 can be moved out from the groove 15 to both sides, so that writing can be done on the writing board 16 or the second writing board 18 using a writing pen, thereby improving the functionality and practicality of this wall-mounted teaching multimedia all-in-one machine.
