Description

Technical Field

[0001] The invention relates to the technical field of teaching tools, in particular to a movable lecture platform for English ideological and political education. Background Art

[0002] The English Ideological and Political Special Movable Lecture Platform is specially designed for classrooms, integrating convenient mobility and stable presentations. The bottom integrates load-bearing wheels and one-button lock, allowing for easy movement in the classroom and instant stability. The built-in lifting and shock absorption system allows for precise height control, shock absorption and stability during movement, improving classroom interaction and professionalism, and achieving significant teaching results.

[0003] The patent application with application number CN201811189105.0 discloses a movable podium for ideological and political use. The height can be adjusted according to the needs of the speaker, and the angle can be rotated to facilitate communication with the audience. The folding desk combination on the podium can adjust the height to facilitate the speaker to place speech manuscripts and other materials. The podium can be folded to facilitate storage after the speech. The movable stairs facilitate the speaker and the audience to go up and down, making the interaction between the speaker and the audience smoother during ideological and political speeches.

[0036] There are two groups of linkage mechanisms 625, and the two groups of linkage mechanisms 625 are symmetrically arranged in the gap between the two groups of inertial sliding mechanisms 62 with the center line of the shock-absorbing platform 2 as the symmetry axis. The sliding sleeve four 6251 is slidingly connected to the outer wall of the rotating sleeve 622 of the inertial sliding mechanism 62 located at the top of the inner wall of the podium shell 1, and the hinge rod eight 6254 is fixedly connected to the outer wall of the rotating sleeve 622 of the inertial sliding mechanism 62 located at the bottom of the relay slide 7.

[0037] The working principle of this embodiment is as follows: when the movable podium for English ideological and political education is put into use, the speaker stands on the surface of the shock-absorbing platform 2, and the cylinder 5 drives the platform shell 1 to rise and fall to adjust the height of the shock-absorbing platform 2. When the podium needs to be moved, the universal wheel 4 at the bottom of the supporting base 3 is unlocked, and the podium is pushed to move the podium to a suitable position and then the universal wheel 4 is locked. When the podium is pushed, the shock-absorbing platform 2 is damped by the shock-absorbing mechanism 61, and at the same time, the inertial sliding mechanism 62 allows the speaker to resist the inertia generated by the shock-absorbing platform 2. The speaker stands on the shock-absorbing platform 2, and the support mechanism 613 drives the rotating sleeve 622 to rotate on the outer wall of the fixed rod 621. At the same time, the articulated rod 7 6252 and the articulated rod 8 6254 of the linkage mechanism 625 slide on the inner wall of the limiting sleeve 2 6253. When the speaker pushes the platform, the speaker generates inertia on the shock-absorbing platform 2, causing the shock-absorbing platform 2 to slide on the inner wall of the relay slide plate 7. The shock-absorbing platform 2 is driven by the support mechanism 613 to make the clamping mechanism 62 The sliding sleeve 3 6241 and the clamping block 6242 of 4 slide on the outer wall of the screw 628, and at the same time, the clamping block 6242 compresses the spring 4 6244 to make the sliding rod 6243 slide on the inner wall of the sliding sleeve 3 6241. At the same time, the spring 4 6244 squeezes the clamping block 6242 and the threaded clamping connection of the outer wall of the screw 628. The spring 5 626 squeezes the sliding sleeve 3 6241 to make the screw 628 rotate, so that the sliding sleeve 3 6241 drives the shock absorbing platform 2 to reset through the supporting mechanism 613. Similarly, when the shock absorbing platform 2 receives the inertia in the square direction, the relay The slide plate 7 slides on the inner wall of the podium shell 1, and at the same time drives the fixed rod 621 and the rotating sleeve 622 of the inertial sliding mechanism 62 located at the bottom of the relay slide plate 7 to move. Through the movement of the rotating sleeve 622, the sliding sleeve 4 6251 of the linkage mechanism 625 drives the clamping mechanism 624 of the inertial sliding mechanism 62 located at the top of the inner wall of the podium shell 1 to slide on the outer wall of the screw 628, and slowly resets through the clamping connection, so that when the podium is moved with people, the inertia brought by the push of the podium to prevent the speaker from causing the speaker's center of gravity to be unstable.

[0042] The working principle of this embodiment is as follows: when the speaker stands on the surface of the shock absorbing platform 2, the shock absorbing platform 2 drives the sliding plate 611 to descend, so that the hinged rod 5 6145 and the hinged rod 6 6147 compress the spring 3 6148 to slide on the inner wall of the sliding sleeve 2 6146.

The fixed block 6144 is supported so that the hinged rod five 6145 and the hinged rod six 6147 support the sliding plate 611 to prevent the podium from vibrating when moving and causing the speaker's center of gravity to be unstable. When the podium moves, inertia drives the shock-absorbing platform 2 to slide on the surface of the sliding plate 611, so that the shock-absorbing platform 2 drives the support rod 6131 to slide in the sliding groove 1 612, driving the relay slide 7 and the clamping mechanism 624 of the inertial sliding mechanism 62 arranged at the bottom of the relay slide 7 to slide on the outer wall of the screw 628, so that the inertial sliding mechanism 62 is started to eliminate the inertia generated by the shock-absorbing platform 2.
