Description

A podium for thinking political affairs education

Technical Field

The invention relates to the technical field of podium, in particular to a podium for thinking administration education.

Background

The podium originally refers to a platform of ancient romans, where the officers, politicians, advocates and other lecturers speak to the aggregated roman people for criminal judgment. The first lecture station was a temple formed by the saints of a speaker, and was established in the ancient Roman square in the Roman republic of China, in an outdoor venue located near the ancient Roman square, as early as the 4 th century before the convention. The lecture table now refers broadly to the table used by the speaker. Are typically made of wood or metal. The height is typically between 1.1m and 1.3 m. The traditional podium is simple in function.

Ideological and political education is a social or social group which applies purposeful, planned and organized influences on members of the society or social groups by using certain ideological concepts, political views and moral specifications, so that the members form social practice activities meeting the ideological and political requirements of a certain society, and are texts for lifelong learning in Chinese literature. At present, a lecture table is adopted to perform lectures no matter the lectures, reports or lectures of ideological and political education are performed in class or the lectures, reports or lectures of ideological and political education are performed in extracurricular or public places, and the lecture table can help the lecturers to store manuscript materials and the like.

However, the overall height and shape of most of the existing lectures for thinking administration education are fixed and cannot be adjusted and used as required, so that the lectures are inconvenient to use and cannot meet more use requirements, and meanwhile, most of the lectures for thinking administration education do not have a structure which is stable and can provide seats for the lecturer when being used, so that the lecturer can not sit conveniently and the lectures have poor practicability when the lectures are used for a long time or are tired.

the supporting platform 2, the height of the platform can be increased to reach the height of a normal platform, the overall height of the platform is smaller than the height of the normal platform when the platform is not used, when the telescopic platform 26 extends out, the universal wheels 1 can be separated from the ground to enable the bottom of the telescopic platform 26 to support the platform, the platform is ensured to be stably placed in the use process, and the platform which is originally smaller than the normal height can be deformed to reach the height and appearance of the normal platform by the motor 28 after being electrified, therefore, the podium can be contracted when not used and the occupied space can be reduced, when the height of the podium needs to be adjusted, the cross bar 59 can be moved leftwards through the clamping connection of the clamping block 64 and the clamping groove 63, so that the clamping block arranged on the outer surface of the connecting rod 29 can be clamped with the clamping groove 63 on the right side in the cross bar 59, the position of the cross bar 59 can be changed, the connection between the connecting rod 29 and the cross bar 59 is not influenced, and the outer surface of the cross bar 59 falling on the left side of the support platform 2 can be held by a hand through the U-shaped frame 60 to move leftwards, so that the cross bar 59 can drive the bevel gear II 42 to move leftwards to be disengaged from the bevel gear I41, but the straight gear 68 in the bevel gear II 42 is still engaged with the teeth 67, and the motor 28 can be started to enable only the bevel gear III 43 to rotate, so that the telescopic platform 26 can be lifted to adjust the height of the podium, thereby the podium can meet more use requirements, meanwhile, when the lecture time is long or the lecturer is somewhat accumulated, the door panel 55 connected with the front surface of the support platform 2 through the hinge can be opened, then the seat plate 5 accommodated in the accommodating groove 3 arranged on the front surface of the support platform 2 is rotated out of the accommodating groove 3 through the first rotating rod 8 by the handle 13, and when the seat plate 5 is rotated out of the accommodating groove 3, the support plate 10 is rotated to the position vertical to the seat plate 5 through the second rotating rod 22 and the position of the support plate 10 is fixed through the fastening bolt 12, then the support plate 18 is slid to move to be attached to the ground through the sliding plate 25 in the sliding groove 23 arranged in the support plate 10 through the first adjusting bolt 17, and when the support plate 18 is attached to the ground, the first adjusting bolt 17 is screwed to be connected with the threaded hole 24 arranged in the sliding plate 25, therefore, the supporting pad 18 is firmly connected with the supporting plate 10 through the sliding plate 25, so that the lecturer can sit on the cushion 9 fixedly connected with the top end of the seat plate 5 to perform the lecture, and the lecture table has stronger practicability.
