Description

Technical Field

[0001] The utility model relates to the technical field of lecture tables, in particular to a lifting lecture table. Background Art

[0002] A lecture table, also known as a report table or podium, is a table designed for speakers, reporters or teachers to give speeches, reports or lectures in formal occasions. Its design usually takes into account the needs of the speaker, such as placing items such as manuscripts, laptops, water cups, and providing a comfortable writing or operating space. The style and size of the lecture table may vary depending on different occasions and uses. For example, some lecture tables may be equipped with built-in microphones and power sockets so that speakers can use electronic devices more conveniently. In addition, the height and tilt angle of the lecture table will also take into account the speaker's comfort to reduce fatigue from standing for long periods of time. In formal occasions, the presence of the lecture table not only provides a stable platform for the speaker, but also helps the audience concentrate and better understand and receive the content of the speech. In addition, the lecture table is also an important connection point between the speaker and the audience, which helps to build trust and communication between the speaker and the audience.

[0003] In the structural composition of a lecture table, the desktop is generally arranged above a bracket, and the bracket is a liftable bracket. The existing liftable bracket is generally composed of a sleeve and an insert. The insert is inserted into the sleeve, and a hole is drilled on the sleeve to install a screw. After the insert is lifted and lowered into place, the screw is used to clamp the inner insert. This single-point fixation has the disadvantage of being easily loosened. Therefore, the utility model proposes a liftable lecture table to solve the problems existing in the prior art. Summary of the invention

[0004] In view of the above problems, the utility model proposes a liftable lecture table. When the liftable lecture table needs to be fixed, it only needs to tighten the bolts so that the fixing plates are pressed inwardly toward the outer columns, and the oblique slope feet on both sides clamp the outer columns, thereby fixing the inner columns. The two-point clamping on both sides achieves the purpose of fastening and fixing.

[0005] To achieve the purpose of the utility model, the utility model is implemented by the following technical solutions: a lifting lecture table, including outer columns and inner columns, the outer columns and inner columns are each provided with two groups, the two groups of outer columns are respectively provided on both sides of the top of the mobile frame, the two groups of inner columns are respectively inserted into the inside of the two groups of outer columns, and the tops of the two groups of inner columns are provided with a podium table, and the inner sides and the lower parts of the front ends of the two groups of inner columns are provided with back panels and trays in sequence;

[0006] A front groove is provided at the front end of the outer column, and a connecting rod is provided above the front end of the front groove. A fixing plate is installed below the front end of the inner column by bolts. The fixing plate is located at the front end of the front groove, and slope feet are obliquely provided on both sides of the fixing plate, and the slope feet are used to clamp the outer column.

[0007] A further improvement is that a mounting hole is provided below the front end of the inner column, and a nut is provided inside the mounting hole, and the nut is matched with the bolt.

[0008] A further improvement is that the mobile frame comprises a base and universal wheels, the universal wheels are arranged at the four corners of the bottom of the base, and a braking device is provided on the universal wheels.

[0009] A further improvement is that a first bracket is provided below the front ends of the two groups of inner columns, and the tray is fixedly mounted to the first bracket by screws.

[0010] A further improvement is that side panels are provided on both sides of the back panel, and the back panel is fixed to the inner column by screws cooperating with the side panels.

[0011] A further improvement is that a second bracket is provided on the top of the two groups of inner columns, and the second bracket is arranged at an angle, and the podium table top is fixed to the second bracket by screws.

[0012] A further improvement is that a book stop bar is provided at the front end of the podium desktop, and the book stop bar is L-shaped, and the book stop bar is fixed to the podium desktop by screws.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model forms a bracket for lifting the podium desktop through an outer column and an inner column. The fixing plate installed on the inner column by bolts passes through the front slot and is located at the outer end of the outer column. When fixing is needed, it is only necessary to tighten the bolts so that the fixing plate is pressed inwardly toward the outer column, and the oblique slope feet on both sides clamp the outer column, thereby fixing the inner column. The two-point clamping on both sides achieves the purpose of fastening and fixing.

[0015] 2. The utility model can place books and other speech materials through the inclined podium table and the limit of the book stop strip. The shielded placement space formed by the backboard and the tray can be used to place materials or other equipment. The universal wheels facilitate overall movement and braking. The overall function is more comprehensive and suitable for the needs of speeches. BRIEF DESCRIPTION OF THE DRAWINGS
