Technical Field

[0001] The utility model relates to the technical field of teaching assistance, in particular to a multimedia device. Background Art

[0002] Multimedia is the combination of computer and video technology. In fact, it is two media: sound and image. Multimedia technology is not a simple combination of various information media. It is an information technology that combines information in the form of text, graphics, images, animation and sound, and performs comprehensive processing and control through computers. It can support the completion of a series of interactive operations. The development of multimedia technology has changed the field of computer use. With the improvement of education level, schools have gradually used multimedia teaching, which not only enables students to learn knowledge more vividly, but also facilitates teaching for teachers.

[0003] Among them, a multimedia device disclosed in application number CN202121780486.7 is also an increasingly mature technology. The demonstration board is set on the demonstration board clamp, and the demonstration board is fixedly connected to the demonstration board clamp. The demonstration support is set above the demonstration board clamp, and the demonstration support is rotatably connected to the demonstration board clamp. There are two movable sliders, which are respectively set on the demonstration support and the movable slide plate. Both movable sliders are fixedly connected to the demonstration support, and both movable sliders are slidably connected to the movable slide plate.

[0004] A multimedia advertising device disclosed in CN202020460200.6 is also an increasingly mature technology. Through the support seat, the first connecting seat, the second connecting seat, the water tank, the water pipe, the motor, the screw rod, the slider, the limit block, the limit rod and the cleaning roller, the water pipe connected to the water tank is used to spray water on the advertising box, and then the motor is used to drive the screw rod to rotate, and the screw rod drives the slider to move, so that the limit block connected to the cleaning roller slides on the outside of the limit rod, thereby moving the cleaning roller to clean the advertising box, reducing the labor of the staff to clean the advertising box and facilitating the operation of the staff.

[0005] Based on this, we agree with the advantages of the above products, but there are still the following defects:

[0006] The heights and angles of the two multimedia devices are fixed, which makes it inconvenient for people to adjust them to the best position, reducing the practicality of the projector and making it inconvenient to use. Moreover, if the multimedia is placed in the house, dust will fall for a long time, which will affect the normal use and life of the multimedia. Utility Model Content

[0007] The purpose of the utility model is to provide a multimedia device to solve the problems in the above background technology that the height and angle are inconvenient to adjust and the normal use and life of the multimedia are affected.

[0008] The embodiment of the utility model provides a multimedia device, including an angle adjustment component and a height adjustment component;

[0009] The angle adjustment assembly includes a frame, a projector is installed near the top of the frame, a rotating shaft is installed in the middle of both ends of the projector and a support shaft is fixedly connected at the outer end, the two support shafts are located in the rotating groove of the disk and are rotatably connected, and the disk runs through both ends of the frame;

[0010] The height adjustment component includes a sleeve, two pillars are slidably installed inside the sleeves, and a plurality of limit holes are opened on the corresponding sides of the two pillars. The sleeves are each provided with a positioning hole near the top, and a positioning pin is installed inside the positioning hole.

[0011] In this embodiment, when adjusting the angle, the user manually rotates the projector, and the support shafts 113 of the rotating shafts at both ends of the projector are rotated and connected along the rotating groove of the disc. When adjusting the height, the positioning pin is pulled out, the frame is slid to a suitable position, the limiting hole of the pillar is overlapped with the positioning hole of the sleeve, and the positioning pin is inserted into the overlapping positioning hole to fix the adjusted pillar.

[0012] In an implementation manner of the utility model, a sonicator is installed near the bottom of the frame, and both ends and the bottom of the sonicator are connected to connecting plates, and the connecting plates are connected to the inner side walls of the frame.

[0013] In this solution, the sound is provided by the sound wave device, so that the projector has an audio playback function, which improves the viewing experience, and the sound wave device is fixed to the inner wall of the frame through a connecting plate.

[0018] In one embodiment of the utility model, a symmetrical fixing block is installed on the top of the frame and a handle is installed in the middle. The bottoms of both ends of the handle are rotatably installed in the circular holes of the fixing block through circular axes. The width of the frame is narrower than that of the projector and the sonicator.

[0019] In this solution, the handle makes it easy for users to take the multimedia device, and the width of the frame is narrower than that of the projector and the sound wave device, which can improve the aesthetics of the multimedia device.

[0020] In one embodiment of the utility model, a bottom plate is fixedly installed at the bottom of the sleeve and a rubber pad is installed at the bottom, reinforcing ribs are installed on both sides of the sleeve, and the top of the support is fixedly connected to the bottom of the frame.

[0021] In this solution, the rubber pad can reduce vibration, protect the multimedia, increase safety and friction, and the reinforcing ribs increase stability for the sleeve.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] 1.
