It can not only improve the teaching effectiveness of teachers, but also improve students' enthusiasm for learning. At the same time, it also provides a convenient and comfortable classroom facility for teaching, which has a significant impact on the quality and efficiency of education and teaching. Therefore, the importance of the setting of the podium to education and teaching cannot be underestimated. Nowadays, with the development of science and technology, more and more classroom podiums have been replaced with more functional podiums to make teaching more convenient.

[0003] In the prior art, the multimedia devices of most classroom desks are fixedly installed under the cover. When the multimedia devices need to be used, the cover needs to be opened manually. However, because the multimedia devices are not level with the desktop, there will be a height difference when the teacher uses them. The teacher needs to bend over to operate the multimedia devices, which has a certain impact on teaching. At the same time, the teacher also needs to manually open the cover to use it, which is extremely inconvenient. In this regard, we propose a multifunctional classroom desk to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0020] Embodiment 1:

[0021] like Figure 1-Figure 3 As shown, the multifunctional classroom desk comprises a desk body 100, a switch assembly 101 is provided at the front end of the desk body 100, a slide rail 102 is fixedly mounted at the upper ends of the front and rear walls of the desk body 100, a cover plate 103 is symmetrically slidably provided at the upper ends of the slide rail 102, and a lifting mechanism is provided inside the desk body 100;

[0022] The lifting mechanism includes a motor 104, a screw 105, a sliding frame 106 and a fixed plate 107. The motor 104 is fixedly installed at the lower end of the table body 100, and the motor 104 is electrically connected to the switch assembly 101. The rotating shaft of the motor 104 is fixedly connected to the screw 105, and the screw 105 is threadedly connected to the sliding frame 106. The fixed plate 107 is fixedly arranged inside the table body 100, and the sliding frame 106 slides through the fixed plate 107. The upper end of the sliding frame 106 is fixedly installed with a mounting groove 108, and the front and rear walls of the mounting groove 108 are symmetrically hinged with connecting rods 109. The inner sides of the front and rear walls of the cover plate 103 are provided with sliding grooves 110, and the ends of the connecting rods 109 are slidably hinged in the sliding grooves 110. A supporting mechanism is provided at the upper end of the mounting groove 108.

[0023] The table body 100 is used to install various parts and components, while protecting the internal structure and extending the service life. The switch assembly 101 can facilitate the teacher to turn on the motor 104. The slide rail 102 can make the cover plate 103 slide. The cover plate 103 is used for the teacher to place the teaching aids needed for the lecture, and can also protect the multimedia device 201 from damage when not in use. The motor 104 is used to drive the screw rod 105 to rotate. The rotation of the screw rod 105 can drive the sliding frame 106 to move up and down. The movement of the sliding frame 106 can drive the installation slot 108 to move up and down. The fixing plate 107 is used to limit the sliding frame 106 from deflection when moving. The installation slot 108 is used to install the multimedia device 201. The connecting rod 109 is used to connect the installation slot 108 and the cover plate 103. The slide slot 110 is used to limit the sliding of the connecting rod 109.

[0024] During use, the teacher turns on the motor 104 through the switch assembly 101, driving the screw 105 to rotate, thereby moving the sliding frame 106 upward, driving the installation slot 108 to move upward. At this time, the installation slot 108 drives the connecting rod 109 to move. Under the limiting action of the sliding slot 110, the connecting rod 109 pushes the cover 103 to move relative to both sides while moving. When the installation slot 108 is horizontal with the upper end of the cover 103, the motor 104 stops rotating. At this time, the cover 103 is opened, and the multimedia device 201 is at the same level as the upper end of the cover 103, which is convenient for the teacher to use.

[0025] In this embodiment, by setting up a lifting mechanism, the multimedia device 201 and the cover 103 are in the same horizontal plane, and there is no height difference when in use. The teacher does not need to bend over to use it, which improves the teaching quality to a certain extent. At the same time, there is no need to manually open the cover 103, which brings certain convenience to the use of the device.

[0026] Embodiment 2:

[0027] Based on the first embodiment, the multifunctional classroom desk is further described. Figure 1-Figure 3 As shown, the supporting mechanism includes a rack 200, a multimedia device 201 and a supporting frame 202. The left and right walls of the mounting groove 108 are fixedly equipped with racks 200. The rack 200 is an oblique rack 200, which is used to fix the position of the supporting frame 202. The front part of the mounting groove 108 is rotatably equipped with a rotating rod 203, and the rotating rod 203 can rotate the multimedia device 201. The multimedia device 201 is fixedly sleeved on the outer side of the rotating rod 203. The multimedia device 201 is a prior art and will not be described here. It is used for teaching. The rear end of the multimedia device 201 is rotatably equipped with a supporting frame 202 that cooperates with the rack 200. The supporting frame 202 is used to fix the lifting angle of the multimedia device 201.

[0028] A plurality of placement boxes 300 are slidably disposed on the left and right parts of the table body 100. The placement boxes 300 are used to place teaching aids or books and homework used for teaching.

[0029] The upper ends of the left and right walls of the installation groove 108 are both chamfered, and the chamfering can make the sliding of the cover plate 103 and the rising of the installation groove 108 smoother.

[0030] A handle 301 is fixedly mounted on the front end of each placement box 300, and the handle 301 is convenient for the teacher to pull out the placement box 300.

[0031] When in use, the teacher lifts the multimedia device 201 to a certain angle so that the support frame 202 is locked in the rack 200, so that the support frame 202 and the multimedia device 201 form a triangle, and the angle of the multimedia device 201 can be fixed. When it needs to be folded, the teacher only needs to pull the support frame 202 out of the rack 200 to make the multimedia device 201 horizontal, thereby achieving the purpose of quick storage.

[0032] In this embodiment, by providing a supporting mechanism, the teacher can adjust the angle at will when using the multimedia device 201, and can quickly store it without delaying the teaching time, and the structure is simple, which greatly improves the practicality of the device.

[0033] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
