Embodiment 1

[0038] A teaching podium with a hidden projector, refer to Figure 1-Figure 8 , including a podium 1, a guide rod 2, a first slide rod 3, a first support rod 4, a placement frame 5, a projector 6, a lifting component 7 and a rotating component 8, and the lower parts of the front and rear sides of the inner wall of the podium 1 are symmetrically welded With the guide bar 2, the teacher can place some teaching tools on the top of the podium 1, the inside of the guide bar 2 is slidably provided with the first slide bar 3, and the tops of the front and back two first slide bars 3 on the same side are provided with the first slide bar 3. A support rod 4, the top of the first support rod 4 is rotatably provided with a placement frame 5, and a projector 6 is placed on the top of the placement frame 5. When the projector 6 is started, the teacher can use the projector 6 to carry out auxiliary teaching. The lower part is provided with a lifting assembly 7, and the inner upper part of t...

Embodiment 2

[0043] On the basis of embodiment 1, refer to image 3 , Figure 9 and Figure 10 , also includes a clamping assembly 9, the clamping assembly 9 includes a connecting block 901, a clamping block 902 and a first spring 903, the upper parts of the left and right sides of the placement frame 5 are slidingly provided with connecting blocks 901, and the inner sides of the connecting blocks 901 are The front and back are symmetrically welded with clamping blocks 902 , the inner sides of the clamping blocks 902 are in contact with the projector 6 and can clamp the projector 6 , and the first springs 903 are arranged between the outer sides of the clamping blocks 902 and the placement frame 5 .

[0044] Initially, the first spring 903 is in a compressed state, and the clamping block 902 can clamp the projector 6 to prevent the projector 6 from slipping when rotating. When people need to repair the projector 6, they can directly put the projector 6 Take it out, so that the projector ...

Abstract

The invention relates to a teaching platform, in particular to a teaching platform with a hidden projector. According to the teaching platform with the hidden projector, the angle of the projector can be adjusted. The teaching platform with the hidden projector comprises a platform body, guide rods, first sliding rods, first supporting rods and the like, the guide rods are arranged on the lower portions of the front side and the rear side of the inner wall of the platform body in a bilateral symmetry mode, the platform body is used for containing some teaching aids, and the first sliding rods are arranged on the inner sides of the guide rods in a sliding mode; a first supporting rod is arranged between the tops of the two first sliding rods on the same side in the longitudinal direction. The groove drum can be driven to rotate positively and negatively by rotating the turntable positively and negatively, so that the placement frame and the projector can be driven to move up and down to achieve the purpose of adjusting the height of the projector, and then the placement frame and the projector can be driven to rotate through the cooperation of the straight gear and the tooth block to achieve the purpose of adjusting the angle of the projector.

Description

technical field [0001] The invention relates to a teaching platform, in particular to a teaching platform with a hidden projector. Background technique [0002] At present, some teachers use projectors to assist teaching when conducting teaching guidance, but the existing projectors are generally installed on the top of the wall, which is inconvenient for people to maintain. [0003] Patent application CN109043822B, with a publication date of 20210209, discloses a teaching platform for hiding a projector, including legs and a table top. There are projection holes and screen holes communicating with the inner cavity of the shell respectively; when the elliptical plate rotates to the longest vertical direction, the projection plate will rotate upwards around the hinge, and the groove of the upper cover will be opened at this time , when the elliptical board is rotated to the longest horizontal direction, the projection board will close the groove of the upper cover at this ti...
