Description

Technical Field

[0001] This utility model relates to the field of lectern technology, and in particular to an electric lectern. Background Technology

[0002] The classroom is the main place for learning, and the podium is the most frequently used teaching tool for teachers. A good podium can bring a lot of convenience to students and teachers and can also improve teaching efficiency.

[0003] Traditional teaching platforms currently have certain shortcomings, such as:

[0004] 1. Fixed height and poor adaptability: It cannot adapt to the needs of teachers of different heights, and long-term bending over to teach can easily cause lumbar spine diseases;

[0005] 2. Severe dust pollution: The lectern in the classroom is usually placed in front of the blackboard. When wiping the chalk writing, chalk dust will spread, resulting in excessive dust in the air and the lectern table being covered with dust, which can easily cause teachers to develop pneumoconiosis.

[0006] Therefore, in order to solve the aforementioned problems, we propose an electric lectern. Utility Model Content

[0007] The purpose of this utility model is to address the deficiencies in the existing technology by proposing an electric lectern.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An electric lectern includes a movable base, a box fixedly installed on the top of the movable base, the top of the box having an open structure, a lifting frame slidably installed on the upper side of the inner side of the box, a table fixedly installed on the top of the lifting frame, and baffles fixedly installed on the front and left and right sides of the top of the table.

[0010] A door is movably installed on the rear side of the box, a fixed frame is fixedly installed on the bottom of the inner side of the box, an electric push rod is fixedly installed on the top of the fixed frame, and the output end of the electric push rod is fixedly connected to the bottom of the table.

[0011] A mounting bracket is fixedly installed on one side of the box, and a blackboard eraser assembly is hung inside the mounting bracket. A vacuum cleaner is fixedly installed at the bottom inside the mounting bracket, and a telescopic hose is fixedly connected to one side of the vacuum cleaner. One end of the telescopic hose passes through the box and communicates with the blackboard eraser assembly.

[0012] Furthermore, a keyboard bracket is slidably installed on the rear side of the bottom of the tabletop, and multiple cable routing holes are provided inside the tabletop.

[0013] Furthermore, the blackboard eraser assembly includes a housing, a brush core is fixedly installed on one side of the housing, and several dust suction holes are opened on both the side of the housing and the inside of the brush core.

[0014] Furthermore, a handle and a control switch are fixedly installed on the other side of the housing, and the control switch is electrically connected to the vacuum cleaner.

[0015] Furthermore, a speaker is fixedly installed on one side inside the mounting bracket, and a microphone is fixedly installed on the top of the tabletop, with the microphone electrically connected to the speaker.

[0016] Furthermore, a sound-permeable opening is provided on the lower front side of the enclosure, the sound-permeable opening corresponds to the speaker, and a dustproof mesh is fixedly installed inside the sound-permeable opening.

[0017] Furthermore, multiple hooks are fixedly installed on the right side of the box.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] The push rod of this invention drives the tabletop to rise and fall, thus adapting the tabletop to the teacher's height and preventing lumbar spine problems caused by prolonged bending over while teaching. Furthermore, the blackboard eraser assembly of this invention, when used with a vacuum cleaner, can absorb the dust from erasing chalk, effectively preventing dust dispersion and reducing the probability of teachers developing occupational lung diseases. The microphone and speaker setup also reduces the risk of vocal cord damage, effectively protecting teachers' health. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0028] Reference Figure 1-5 An electric lectern includes a movable base 1, a housing 2 fixedly mounted on the top of the movable base 1, the top of the housing 2 being an open structure, a lifting frame 3 slidably mounted on the upper inner side of the housing 2, a tabletop 4 fixedly mounted on the top of the lifting frame 3, and baffles fixedly mounted on the front and left and right sides of the top of the tabletop 4; a door movably mounted on the rear side of the housing 2, a fixing frame 10 fixedly mounted on the bottom inner side of the housing 2, an electric push rod 11 fixedly mounted on the top of the fixing frame 10, and the output end of the electric push rod 11 fixedly connected to the bottom of the tabletop 4;

[0029] The movable base 1 allows for flexible movement of the lectern. The bottom of the movable base 1 is equipped with casters, which have locking mechanisms to lock the casters and secure the movable base 1.

[0030] Teachers can place teaching materials and other items on top of the tabletop 4. A controller can be installed on the tabletop 4, which is electrically connected to the electric push rod 11. The teacher can use the controller to control the electric push rod 11 to raise and lower the tabletop 4, thus adapting the tabletop to the teacher's height. A baffle installed on the outside of the tabletop 4 can prevent objects from falling off the tabletop 4.

[0031] A mounting bracket 6 is fixedly installed on one side of the housing 2. A blackboard eraser assembly is hung inside the mounting bracket 6. A vacuum cleaner 12 is fixedly installed at the bottom inside the mounting bracket 10. A telescopic hose 8 is fixedly connected to one side of the vacuum cleaner 12. One end of the telescopic hose 8 passes through the housing 2 and is connected to the blackboard eraser assembly.

[0032] Teachers or students can use the blackboard eraser assembly to wipe and clean the chalk writing on the blackboard. The dust generated during wiping can be absorbed by the vacuum cleaner 12 and the telescopic hose 8, which greatly reduces the dispersion of chalk dust, effectively protects the health of teachers or students, and significantly reduces the probability of teachers suffering from occupational lung diseases.

[0033] A keyboard bracket 5 is slidably installed on the rear side of the bottom of the tabletop 4. Multiple cable management holes are provided inside the tabletop 4. The keyboard bracket 5 is existing technology and is used to place the keyboard. The top of the fixing frame 10 inside the housing 2 can hold the computer case. The top of the tabletop 4 can hold the monitor. The transmission cable between the computer case and the monitor can be passed through the cable management holes to avoid messy wiring.

[0034] The blackboard eraser assembly includes a housing 7, with a brush core 16 fixedly mounted on one side of the housing 7. Both the side of the housing 7 and the interior of the brush core 16 have several suction holes 17. A handle 18 and a control switch 19 are fixedly mounted on the other side of the housing 7, and the control switch 19 is electrically connected to the vacuum cleaner 12.

[0035] Teachers or students can lift the housing 7 using handle 18 and turn on the vacuum cleaner 12 using control switch 19. They can then use the brush 16 to wipe the blackboard. The chalk dust produced during wiping enters the housing 7 through the suction port 17 and then flows into the dust collector 12 through the telescopic hose 8. The vacuum cleaner 12 is existing technology and can be selected according to actual needs.

[0036] A speaker 13 is fixedly installed on one side inside the mounting bracket 10, and a microphone 9 is fixedly installed on the top of the table 4. The microphone 9 is electrically connected to the speaker 13. A sound transmission port 15 is provided on the lower front side of the cabinet 2, which corresponds to the speaker 13. A dustproof mesh is fixedly installed inside the sound transmission port 15.

[0037] Teachers can use microphone 9 and speaker 13 to amplify the volume when lecturing, avoiding excessive use of their voices and potential damage to their vocal cords. Microphone 9 can also be a Bluetooth microphone, which can be worn on the teacher's face to improve flexibility.

[0038] Multiple hooks 14 are fixedly installed on the right side of the box 2, which can be used to hang items such as handbags.
