A hydraulic extension rod 3 is sealed and movably sleeved, a support plate 4 is fixedly installed at the bottom of the hydraulic extension rod 3, one side of the four hydraulic cylinders 11 is connected with a hydraulic pipe 16, the opposite end of the hydraulic pipe 16 is connected with an output pipe 24, a first non-return valve 19 is movably installed inside the hydraulic pipe 16 near one end of the output pipe 24, the end of the output pipe 24 away from the hydraulic pipe 16 is connected with a hydraulic output pump 17, the input end of the hydraulic output pump 17 is connected with a hydraulic oil tank 18, the top of the hydraulic pipe 16 is connected with a return pipe 21, a third non-return valve 23 is movably installed inside the return pipe 21 near one end of the hydraulic pipe 16, an active solenoid valve 22 is movably installed inside the other end of the return pipe 21, a second non-return valve 20 is movably installed inside the output pipe 24, and four universal wheels 2 are movably installed at the bottom of the podium body 1.

[0021] The working principle of the above technical solution is as follows: when in use, the user first moves the device to a suitable use position through the universal wheel 2, and then starts the hydraulic output pump 17, the hydraulic output pump 17 extracts the hydraulic oil from the hydraulic oil tank 18 and guides it into the output pipe 24, at this time, the hydraulic oil enters the hydraulic pipe 16 through the diversion of the output pipe 24, the second one-way valve 20 and the first one-way valve 19 limit the flow direction of the hydraulic oil from the hydraulic output pump 17 to the hydraulic cylinder 11, the hydraulic pipe 16 guides the hydraulic oil into the hydraulic cylinder 11, and the hydraulic Under the action of hydraulic pressure, the cylinder 11 pushes out the hydraulic extension rod 3, so that the support plate 4 contacts the ground, so that the podium body 1 is lifted and the height is adjusted and then fixed in position. When it needs to be lowered, the active solenoid valve 22 is opened, and the hydraulic oil is discharged from the inside of the hydraulic cylinder 11 under the action of pressure and enters the hydraulic oil tank 18 through the hydraulic pipe 16 and the return pipe 21, so that the pressure in the hydraulic cylinder 11 is released, and then the hydraulic extension rod 3 is retracted to lower the height. This solution can conveniently adjust the height and adjust it evenly, which increases the convenience of use.

[0022] In another embodiment, Figure 1-Figure 3As shown, the reinforcing ribs 14 are linearly and evenly distributed on the inner side of the podium body 1 , the two support columns 15 are cross-distributed with the reinforcing ribs 14 , and the two ends of the support columns 15 are respectively fixedly mounted on the top and bottom of the inner cavity of the podium body 1 .

[0023] The reinforcing ribs 14 and the supporting columns 15 can increase the structural strength inside the platform body 1 and ensure that the platform body 1 does not lose its structural strength while being lightweight, thereby increasing the force and stabilizing the structure.

[0024] In another embodiment, Figure 1-Figure 3 As shown, four hydraulic cylinders 11 are fixedly passed through the lectern body 1 and extend to the bottom of the lectern body 1 .

[0025] The installation method of the hydraulic cylinder 11 cooperates with the fixing frame 12 to increase the strength of the hydraulic cylinder 11 and the bottom structure, stabilizes the use, and ensures good stress resistance of the overall structure.

[0026] In another embodiment, Figure 4 and Figure 5 As shown, the bottoms of the hydraulic output pump 17 and the hydraulic oil tank 18 are both fixedly mounted at the bottom of the inner cavity of the podium body 1 , and one end of the return pipe 21 away from the third one-way valve 23 is connected to the interior of the hydraulic oil tank 18 .

[0027] The return pipe 21 centrally returns the hydraulic pressure of the four hydraulic pipes 16 to the inside of the hydraulic oil tank 18, so as to facilitate stable flow guidance and form a hydraulic oil circuit, thereby achieving good overall use effect and facilitating coordinated operations.

[0028] In another embodiment, Figure 4 and Figure 5 As shown, the first one-way valve 19 is located on the opposite side of the return pipe 21 and the output pipe 24 , the second one-way valve 20 is located on the opposite side of the first one-way valve 19 and the hydraulic output pump 17 , and the third one-way valve 23 is located on the opposite side of the hydraulic pipe 16 and the active solenoid valve 22 .

[0029] The first one-way valve 19 and the second one-way valve 20 limit the flow direction of the hydraulic oil from the hydraulic output pump 17 to the output pipe 24 and the hydraulic pipe 16, and then to the hydraulic cylinder 11 through the hydraulic pipe 16. The third one-way valve 23 limits the direction from the hydraulic pipe 16 to the return pipe 21, and then to the hydraulic oil tank 18 through the return pipe 21, so as to form a reflux. The one-way valve setting makes it easy to avoid flow turbulence, stabilizes the flow direction of the hydraulic oil and increases stability.

[0030] In another embodiment, Figure 2 As shown, the four universal wheels 2 and the hydraulic extension rods 3 are all rectangular and evenly distributed at the bottom of the podium body 1.

[0031] By setting the universal wheel 2 and the hydraulic cylinder 11, the podium body 1 can be conveniently moved with the support of the universal wheel 2, and with the hydraulic extension of the hydraulic cylinder 11 and the hydraulic extension rod 3, it can be moved according to the required position, and can be extended to a fixed position after moving, which increases the convenience of use and is easy to move and fix. The multimedia podium can be moved according to the use requirements and is easy to move, which improves the problem of the traditional podium being difficult to fix or move, and has a good use effect.
