[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The schematic embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0018] like Figure 1-3 As shown: the utility model includes a lecture table assembly, a sliding table top assembly and a lifting sand table assembly. The sliding table top assembly is arranged at the upper end of the lecture table assembly, and the lifting sand table assembly is arranged inside the lecture table assembly.

[0019] Furthermore, the lecture table assembly includes a lecture table 1 and a lifting bracket plate 2, the lifting bracket plate 2 is fixedly arranged in the middle section of the lecture table 1, the lifting sandbox assembly is installed on the lifting bracket plate 2, the upper end of the lecture table 1 is open, and the sliding table top assembly is arranged at the upper end opening of the lecture table 1.

[0020] Furthermore, the sliding table board assembly includes a sliding table board 3, a sliding rail 4, a sliding screw 5, a slider 6, and a slider nut seat 7. The sliding table board 3 consists of two pieces. Two sliders 6 are arranged at the lower end of one side of the two sliding table boards 3. A slider nut seat 7 is fixedly arranged at the lower end of each slider 6. The sliding rail 4 is arranged at the upper end of the inner side of the lecture table 1. The two sliding table boards 3 are slidingly connected to the sliding rail 4 through the slider 6. The sliding screw 5 is threadedly connected to the slider nut seat 7. A slider driving motor is arranged at one end of the sliding screw 5. One end of the sliding screw 5 is fixedly connected to the rotating shaft of the slider driving motor. The slider driving motor is fixedly connected to the lecture table 1.

[0021] Specifically, the lifting sandbox assembly includes a sandbox 8, a lifting screw 9, a rotating shaft 10, a nut worm wheel 11, a worm 12, and a worm motor 13. A through hole is provided in the middle of the lifting bracket plate 2. The nut worm wheel 11 is rotatably connected to the through hole position of the lifting bracket plate 2 through the rotating shaft 10. The sandbox 8 is located in the middle of the lecture table 1. The upper end of the lifting screw 9 is fixedly connected to the middle of the lower end of the sandbox 8. The lower section of the lifting screw 9 is threadedly connected to the middle of the rotating shaft 10. The outer circle of the nut worm wheel 11 is threadedly engaged with the worm 12. The worm 12 is fixedly connected to the rotating shaft of the worm motor 13, and the worm motor 13 is fixedly connected to the lecture table 1.

[0022] The working principle of the utility model is as follows:

[0023] When the utility model is used, when the psychology lecturer does not need the sandbox, the sandbox 8 is located inside the lecture table 1, and the two sliding table boards 3 are combined, and the whole is like a conventional lecture table. When the sandbox is needed, the slider driving motor drives the sliding screw 5 to rotate, and the sliding screw 5 is threadedly connected to the slider nut seat 7. Therefore, when the sliding screw 5 rotates, it will drive the slider nut seat 7 to move, thereby driving the slider 6 to slide on the slide rail 4 through the slider nut seat 7, thereby driving the sliding table board 3 to slide through the slider 6, and the two sliding table boards 3 are unfolded to both sides, exposing the upper end opening of the middle part of the lecture table 1, until the width of the sandbox 8 is exposed. At this time, the worm motor The motor 13 drives the worm 12 to rotate, and the worm 12 drives the nut and worm wheel 11 to rotate. The nut and worm wheel 11 and the lifting bracket plate 2 rotate through the rotating shaft 10. Since the nut and worm wheel 11 are threadedly connected with the lifting screw 9, the lifting screw 9 moves up and down, driving the sand table 8 to rise until the sand table 8 is flush with the sliding table board 3, so that the psychology lecturer can use the sand table placed on the sand table 8 to give lectures. When the sand table needs to be retracted to restore the conventional lecture table, contrary to the above working principle, the worm motor 13 reverses to drive the sand table 8 to descend, and the slider drives the motor to reverse, driving the two sliding table boards 3 to merge, covering the upper end of the lecture table 1 to form a conventional lecture table.

[0024] The above shows and describes the basic principle and main features of the utility model and the advantages of the invention. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
