Technical Field

[0001] The invention relates to the technical field of lecture platforms, in particular to a lecture platform with adjustable height for ideological and political education. Background Art

[0002] However, when giving ideological and political education speeches, due to the large content and long duration of the speeches, standing for a long time poses a huge challenge to the speaker's physical strength. When giving ideological and political education speeches, reports or speeches, fixed tables are used, and the tables are large and inconvenient to move. They require multiple staff members to lift them before they can be moved, which is time-consuming and laborious for the staff and takes up a lot of manpower and material resources. In addition, after a long period of operation, the equipment may contain impurities such as chalk dust, and manual cleaning is required frequently, resulting in low cleaning efficiency. Therefore, a new design was made to address this situation. Summary of the invention

One side of the bottom of the inner wall of the square shell is fixedly connected with a limiting mechanism, and a limiting mechanism is installed on the inner side of the square shell. The limiting mechanism is used to limit the descending range of the connecting base to prevent the electric push rod from malfunctioning and causing the connecting base to descend rapidly inside the square shell, thereby playing the role of braking the descent of the components, reducing the impact force generated by the descent, and reducing the wear between components, thereby extending the service life of the components.

[0012] The present invention provides a height-adjustable podium for ideological and political education, which has the following beneficial effects: 1. The height-adjustable podium for ideological and political education is designed with a composite mechanism. The flip mechanism is arranged on the inside of the composite frame. The teaching materials can be placed on the top of the flip mechanism to carry the teaching materials. The internal components of the flip mechanism are rotated to drive the surface impurities and dust to be processed, thereby reducing manual cleaning by personnel and improving cleaning efficiency. At the same time, the electric push rod is used to control the connecting base to slide on the inside of the square shell to achieve the function of controlling the lifting and lowering of the components, thereby meeting different work needs and providing the user with a range of application. The mobile frame is used to drive the equipment to move, thereby facilitating subsequent transportation and reducing the difficulty of movement. A limiting mechanism is installed on the inside of the square shell to limit the descending range of the connecting base through the limiting mechanism to prevent the electric push rod from malfunctioning and causing the connecting base to descend rapidly on the inside of the square shell, thereby playing the role of braking the descent of the components, reducing the impact force generated by the descent, reducing the wear between components, and thus extending the service life of the components.

[0013] 2. The height-adjustable podium for ideological and political education is designed with a flipping mechanism. The load-bearing plate supports the flipping bracket and carries the teaching materials when they are placed. The motor controls the rotation of the roller, which drives the rotating belt to rotate, so as to adjust the surface of the rotating belt. The impurities on the surface of the moving parts are removed by changing the surface, which saves manual labor in cleaning surface impurities and reduces the need for cleaning in later use. At the same time, the rotating belt rubs against the processing mechanism when it rotates to one side of the processing mechanism, which facilitates the cleaning of debris and dust on the surface of the rotating belt.

[0014] 3. The height-adjustable podium for ideological and political education is designed with a limiting mechanism, and the connecting base slides inside the square shell. When the electric push rod fails, the connecting base slides to squeeze the sliding rod, causing the sliding rod to compress the spring bar, thereby achieving the effect of shock absorption and buffering, and blocking the downward trend of components to avoid collision of components due to excessive sliding speed, which causes serious wear between components. Therefore, the impact is reduced by braking the downward trend of the components, thereby extending the service life of the components. The external block slides with the sliding rod, and the sliding space of the external block is limited by the strip slide groove to prevent excessive sliding, which affects the performance of the components. By limiting the sliding space, a certain protective effect is played on the elastic structure of the spring bar.

[0015] 4. The height-adjustable podium for ideological and political education is designed with a processing mechanism. When the rotating belt rotates toward the processing shell, it rubs against the scraping mechanism to achieve the cleaning effect of the components and reduce the dust and particles on the surface of the components, so as to keep the surface of the components clean. Secondly, the dust is guided by the guide block to avoid dust leakage during the scraping process, thereby affecting the cleaning efficiency. The inner side of the annular frame is connected to the pneumatic mechanism, which absorbs and cleans the dust inside the processing shell. Excessive accumulation on the surface affects the later storage effect. The sliding block slides on the surface of the connecting rod to push the friction block to one side of the annular frame, thereby pushing the dust and debris close to the pneumatic mechanism to ensure that the equipment cleans the dust and pushes the dust to move, which is convenient for the pneumatic mechanism to absorb dust, reduce dust mass, and keep the inside of the equipment clean. Secondly, when some impurities such as paper scraps or components are damaged, the cover plate is pulled for easy cleaning and maintenance.

[0016] 5. The height-adjustable podium for ideological and political education is designed with a pneumatic mechanism. By inserting the pneumatic mechanism into the inner side of the ring frame, it is convenient for disassembly and installation. The wind is generated by the fan and enters from one side of the conical tube to absorb and clean the dust. The dust enters the collection shell through the wind and is temporarily stored through the collection shell. It is convenient for subsequent cleaning through disassembly. Mesh holes are opened on the surface of the conical tube to facilitate dust circulation. Secondly, the rotating mechanism is driven by wind to rotate, and the inner wall of the conical tube is rubbed by the rotating mechanism to clean the inner wall of the pipe, thereby avoiding dust accumulation after long-term operation, thereby affecting the subsequent ventilation effect.

Secondly, a limiting mechanism 19 is provided in the square shell 16, and the limiting mechanism 19 is used to prevent the lifting and lowering of the equipment.

During daily use, the rotating belt 125 may accumulate chalk dust, paper scraps or dust, so it needs to be manually wiped and cleaned by personnel. The motor 124 is used to rotate and change the surface, thereby reducing manual participation, improving cleaning effect and reducing personnel input. Secondly, during the rotation of the rotating belt 125, it contacts the processing mechanism 2, and the rotating belt 125 is rubbed by the scraping mechanism 27 to achieve the effect of cleaning dust and debris, thereby maintaining the continuous surface cleaning of the equipment and keeping the equipment clean. Dust and debris enter the processing shell 21 and play a temporary storage role. The composite equipment is used many times, resulting in faster accumulation of chalk dust, etc., so as to avoid excessive storage inside the processing shell 21, which affects the subsequent cleaning effect. Therefore, by inserting the pneumatic mechanism 3, the fan 31 inside the pneumatic mechanism 3 generates wind force to absorb and clean the dust inside the processing shell 21, so as to facilitate subsequent dumping processing, thereby keeping the inside of the equipment clean and ensuring the continuous normal operation of the equipment.
