Specific Embodiments

[0021] To make the objectives, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0022] As Figures 1 to 5As shown in the figure, a teaching podium includes a support frame 101. A bottom plate 102 is fixed to the lower end of the support frame 101. A tabletop 103 is provided at the upper end of the support frame 101. Wheels for facilitating the movement of the podium are installed at the four corners of the lower end of the bottom plate 102. It also includes two sets of symmetrically arranged placement components for placing objects during a speech, which are provided on the back surface of the tabletop 103. The placement component includes a side plate 201. The side plate 201 is slidably connected to the back surface of the tabletop 103 through a sliding component. A baffle 202 for preventing the object from slipping after being placed on the side plate 201 is fixed to the side plate 201. A driving component for driving the contraction of the two side plates 201 is provided on the tabletop 103.

[0023] When the mobile podium is in operation, through the mutual cooperation of the driving component and the sliding component, the two side plates 201 can be flexibly extended outwards or retracted inwards. While facilitating the placement of more other objects on the mobile podium, it can reduce the occupied area on the tabletop 103 after use, further facilitating the movement and storage of the mobile podium.

[0024] The sliding component includes a strip-shaped plate 301 fixed to the back surface of the tabletop 103. Two fixing blocks 302 are fixed to the strip-shaped plate 301. Connecting blocks 303 are fixed to the upper ends of the two side plates 201. A plurality of guide rods 304 are slidably connected to the connecting blocks 303. The guide rods 304 are fixed between the two fixing blocks 302. The driving component includes a transmission plate 401 provided on one side of the tabletop 103. The side plate 201 is located between the transmission plate 401 and the tabletop 103. Two inclined slots 402 are formed in the transmission plate 401. Two transmission pins 403 are slidably connected to the two inclined slots 402. One ends of the two transmission pins 403 are respectively fixed to the back surfaces of the two side plates 201. A moving component for moving the transmission plate 401 and a guiding component for guiding during the moving process are provided on the back surface of the tabletop 103. Through the mutual cooperation of the moving component and the guiding component, the stressed transmission plate 401 moves along the back surface direction of the tabletop 103. During the movement of the transmission plate 401, through the interaction between the two inclined slots 402 and the two transmission pins 403 respectively, the two side plates 201 are driven to move under force. During the movement of the two side plates 201, through the sliding guiding action of the connecting blocks 303 and the plurality of guide rods 304, the two side plates 201 under force move away from or close to each other.

[0025] The moving component includes a fixing plate 501 fixed to the back surface of the tabletop 103. A threaded tube 502 is rotatably connected to the fixing plate 501. A threaded rod 503 is threadedly engaged with the threaded tube 502. One end of the threaded rod 503 is fixed with a connecting plate 504, and the connecting plate 504 is fixed to the transmission plate 401. When the threaded tube 502 is rotated, during the rotation of the threaded tube 502, through the meshing transmission between the threaded tube 502 and the threaded rod 503, the connecting plate 504 and the transmission plate 401 are driven to move. During the movement of the connecting plate 504, through the guiding component of the guiding assembly, the stressed transmission plate 401 moves along the back direction of the tabletop 103.

[0026] There are two sets of guiding assemblies, and the two sets of guiding assemblies are symmetrically arranged on both sides of the threaded tube 502. Through the two sets of symmetrically arranged guiding assemblies, the guiding stability is improved.

[0027] The guiding assembly includes a sleeve 601 fixed to the fixing plate 501. A sliding rod 602 is slidably connected to the sleeve 601. One end of the sliding rod 602 is fixed to the connecting plate 504. During the movement of the connecting plate 504, through the sliding guiding action of the two sets of sleeves 601 and the sliding rods 602, the stressed transmission plate 401 moves along the back direction of the tabletop 103.

[0028] When the mobile podium is in operation, through multiple sets of wheels at the lower end of the bottom plate 102, it is convenient to assist the podium to quickly move to different occasions for operation.

[0029] When it is necessary to assist in placing other components on the tabletop 103 of the podium for use, the threaded tube 502 is rotated. During the rotation of the threaded tube 502, through the meshing transmission between the threaded tube 502 and the threaded rod 503, the connecting plate 504 and the transmission plate 401 are driven to move. During the movement of the connecting plate 504, through the sliding guiding action of the two sets of sleeves 601 and the sliding rods 602, the stressed transmission plate 401 moves along the back direction of the tabletop 103. During the movement of the transmission plate 401, through the interaction between the two inclined slots 402 and the two transmission pins 403 respectively, the two side plates 201 are driven to move under force. During the movement of the two side plates 201, through the sliding guiding action of the connecting block 303 and the multiple guide rods 304, the two stressed side plates 201 move away from each other, and the two sets of side plates 201 are extended. Through the extension of the two side plates 201, the usable area on the tabletop 103 is increased, and it is further convenient to place more other objects on the mobile podium.

[0030] After the mobile podium is used, through transmission, the two side plates 201 are driven to lean against the back of the tabletop 103 for contraction. Through the contraction effect, the occupied area on the tabletop 103 is reduced, which further facilitates the movement and storage of the mobile podium.
