The bottom surface of the chassis 2-1 of the horizontal winding lifting mechanism 2 is fixedly connected with the sliding block adapted to the internal slide of the hanging rail 1 at the front and rear positions, so that the mechanism can slide left and right on the upper surface of the hanging rail 1.

[0019] The specific structure of the horizontal type winding and lifting mechanism 2 is as follows: the upper surface of the chassis 2-1 is fixed with a sleeve ring 2-2, and the upper end surface of the sleeve ring 2-2 is fixedly connected with a support disc 2-5. The top surface of the support disc 2-5 is fixedly connected with a driving motor 2-4 at the central position, and a through hole is formed in the top surface of the support disc 2-5 for the output shaft of the driving motor 2-4 to penetrate through, and a bearing adapted to the output shaft is arranged inside the through hole. The output shaft of the driving motor 2-4 is connected with an upper support frame 2-6 through a shaft coupling, and a plurality of guide rollers 2-7 are fixedly connected around the bottom surface of the upper support frame 2-6, and the bottom ends of the guide rollers 2-7 are fixedly connected with a lower support frame 2-8. A plurality of winding cables 2-3 are wound between the outer side surface of the guide rollers 2-7 and the inner cavity side wall of the sleeve ring 2-2, one end of the winding cable 2-3 is fixedly connected with the inner cavity side wall of the sleeve ring 2-2, and the other end penetrates downward through the lower support frame 2-8.

The bottom surface of the power terminal 4 is provided with plugs, jacks and lighting equipment for laboratory use.

[0020] During the class, the teacher sends a command through the central control console, and all power terminals are lowered to the predetermined height simultaneously. Specifically, the driving motor 2-4 receives the command and rotates forward, releasing the winding cable 2-3 wound on the guide roller 2-7.

The teacher sets the output voltage through the central control console to the required value, such as 5V DC. The students directly use the powered power terminal 4 for experiments without manual adjustment. After the experiment, the teacher controls all power terminals to automatically rise to the ceiling position for storage. At this time, the driving motor 2-4 reverses, winding the winding cable 2-3 horizontally back onto the guide roller 2-7, thereby lifting the power terminal 4 to the ceiling for storage, and the desktop space is completely released.

[0021] In this embodiment, the multifunctional laboratory lifting power supply system is also composed of a central control console, multiple suspended student power terminals, and a communication bus connecting them. The functions of the central control console are the same as in Example 1, and the teacher can set the output parameters of each power terminal uniformly or individually through the built-in control software, and control its lifting, with the display screen displaying the terminal status in real time.

However, in this embodiment, the distance between the outer surface of the upper support frame 2-6 and the lower support frame 2-8 and the inner cavity side wall of the sleeve ring 2-2 is adjusted to 0.6 cm, and the distance between the two guide frames 2-10 and the layout of the release ring 2-9 are optimized, making the winding and release of the winding cable 2-3 more stable. The structure and function of the sleeve 3 are the same as in Example 1, and the internal partition divides the space, with the left side for the pulling cable 5 to pass through to connect the power terminal 4, and the right side for the power line to pass through. The power terminal 4 at the bottom is also provided with a plug, a socket, and lighting equipment.

[0022] Before class, the teacher presets the descent height and output voltage of the power terminal 4 through the central control console. During class, the descent command is issued by one key, the drive motor 2-4 is driven to rotate forward, the winding cable 2-3 is gradually released, and the power terminal 4 is lowered under the action of gravity through the pulling cable 5 to drive the sleeve 3. When reaching the preset height, the power terminal 4 automatically stops descending. At this time, the power module adjusts the output voltage to the required value according to the central control console command. Students can directly use the power terminal 4 for experiments. After the experiment is completed, the teacher again operates one key to drive the motor 2-4 to reverse, the winding cable 2-3 is wound back to the guide roller 2-7, and the power terminal 4 is raised to the ceiling for storage, releasing the desktop space.

[0023] In this embodiment, the multifunctional laboratory lifting power supply system is composed of a central control console, a plurality of suspended student power terminals, and a communication bus. The central control console has the functions of setting the output parameters of the power terminal and controlling the lifting, and the display screen displays the state in real time. The functions of the modules of the suspended student power terminal remain unchanged, and the horizontal winding and lifting mechanism is installed on the hanging rail 1 of the laboratory ceiling. The installation of the hanging rail 1 and the connection mode of the horizontal winding and lifting mechanism 2 to the hanging rail 1 remain unchanged, and the chassis 2-1 slides left and right through the sliding block. In the horizontal winding and lifting mechanism 2, the rollers on the guide frame 2-10 and the release ring 2-9 are improved. The number of rollers between the mutually close sides of the guide frame 2-10 is increased, and the layout of the rollers on the release ring 2-9 is more reasonable, so that the friction of the winding cable 2-3 when passing through the rollers is more uniform, reducing the wear of the cable. At the same time, the distance between the outer surface of the upper support frame 2-6 and the lower support frame 2-8 and the inner cavity side wall of the sleeve ring 2-2 is adjusted to 0.55 cm, further optimizing the winding and release process of the winding cable 2-3.

During class, the descent command is issued, the drive motor 2-4 is driven to rotate forward, the winding cable 2-3 is released, and the power terminal 4 is lowered. During the descent process, the improved roller structure makes the winding cable 2-3 run more smoothly.

After the experiment is completed, the teacher issues the lifting command, the drive motor 2-4 is driven to reverse, the winding cable 2-3 is wound back to the guide roller 2-7, the power terminal 4 is raised to the ceiling, the desktop space is released, and the whole process is realized through the central control console for convenient remote management.
