The lifting mechanism can drive the power box to rise and fall relative to the storage box via the cable. The distance sensor is mounted on the power box and is used to detect the distance between the power box and a reference surface located below the power box. During the descent of the power box relative to the storage box, when the distance sensor detects that the distance between the power box and the reference surface is less than or equal to a preset value, the lifting mechanism stops driving.

[0037] Please see Figure 1 and Figure 2 , Figure 1 This is a front view of the rope hoisting device 100 provided in this embodiment of the present invention during use; Figure 2 yes Figure 1 This is a front view of the rope hoisting device 100 when it is not in use. This embodiment of the invention provides a rope hoisting device 100, which includes a lifting mechanism 10, a storage box 20, and a power supply assembly 30. The lifting mechanism 10 is installed on the top side of a ceiling 200, and the storage box 20 is installed on the bottom side of the ceiling 200. The power supply assembly 30 includes a power box 31 and a cable 32. One end of the cable 32 is connected to the power box 31, and the other end of the cable 32 passes through the storage box 20 and is connected to the lifting mechanism 10. The lifting mechanism 10 can move the power box 31 up and down relative to the storage box 20 via the cable 32.
[0038] Specifically, the lifting mechanism 10 can be installed and fixed to the ceiling joists on the top side of the ceiling 200 using screws or other fasteners to conceal it and improve its appearance. The storage box 20 can be connected to the lifting mechanism 10 using iron rods or other connectors, allowing the storage box 20 to be suspended from the bottom side of the ceiling 200. The lifting mechanism 10 can be driven by electricity, hydraulic pressure, or pneumatic pressure to drive the cable 32 to raise and lower the power supply box 31. Please refer to [reference needed]. Figure 1 When the power supply box 31 is needed, the lifting mechanism 10 drives the power supply box 31 to a suitable position, so that student users can connect the experimental equipment to the power supply box 31 to complete the experiment. Please refer to... Figure 2 When the power box 31 is not in use, the lifting mechanism 10 drives the power box 31 to rise and be stored in the storage box 20, which can increase the neatness of the appearance. At the same time, the storage box 20 can support the power box 31 to prevent the power box 31 from swinging in the air and damaging the cable 32.
[0039] Please refer to the following in this embodiment: Figure 3 , Figure 3 yes Figure 2A three-dimensional structural diagram of the rope hoisting device 100 is provided. The rope hoisting device 100 also includes a distance sensor 33, which is mounted on the power supply box 31 and used to detect the distance between the power supply box 31 and the reference surface 300 located below the power supply box 31. During the descent of the power supply box 31 relative to the storage box 20, when the distance sensor 33 detects that the distance between the power supply box 31 and the reference surface 300 is less than or equal to a preset value, the lifting mechanism 10 stops operating.
[0040] Specifically, the reference surface 300 can serve as a desktop for student users to place experimental equipment. Understandably, considering the length of the experimental equipment's power cord and user operation, the distance between the power supply box 31 and the reference surface 300 cannot be too small or too large. For example, if the distance is too small, the power supply box 31 will be too low, occupying part of the experimental space and restricting user operation. Conversely, if the distance is too large, the power supply box 31 will be too high, potentially resulting in insufficient power cord length. Therefore, a suitable distance is required between the power supply box 31 and the reference surface 300. However, due to varying installation environments in different classrooms (e.g., inconsistent student desktop heights, different ceiling heights), extensive debugging is often required before deployment, leading to excessively high investment costs.
[0041] The rope hoisting device 100 provided in this embodiment of the utility model, by setting a distance sensor 33 on the power box 31, when the distance sensor 33 detects that the distance between the power box 31 and the reference surface 300 is less than or equal to a preset value during the descent of the power box 31, the lifting mechanism 10 stops driving, so that the power box 31 can be maintained at a suitable height for student users to conduct experiments. Moreover, the rope hoisting device 100 does not require complicated debugging before being put into use, reducing service costs.
[0042] In one embodiment of this implementation, please refer to Figure 3 and Figure 5 , Figure 5 yes Figure 4 The diagram shows a bottom view of the power supply assembly 30. The distance sensor 33 includes a signal transmitter 331 and a signal receiver 332. The signal transmitter 331 transmits a detection signal to the reference surface 300, and the signal receiver 332 receives the detection signal reflected back from the reference surface 300. This configuration allows the distance between the power supply box 31 and the reference surface 300 to be calculated using the transmission and reception times of the detection signal, facilitating real-time measurement of the height of the power supply box 31.
[0043] In one embodiment of this implementation, the detection signal includes at least one of light, ultrasound, and electromagnetic waves. Specifically, the light can be a beam of light such as infrared or laser. The electromagnetic wave can be a radio wave. This configuration can improve the accuracy of real-time measurements.
[0044] In one embodiment of this implementation, please refer to Figure 4 , Figure 4 yes Figure 3 A cross-sectional view of the storage box 20 and the power supply assembly 30 is shown. The storage box 20 has a receiving groove 201 on its bottom side, and the lifting mechanism 10 can drive the power supply box 31 to rise and be stored in the receiving groove 201. This arrangement allows the power supply box 31 to be stored inside the storage box 20, enabling the storage box 20 to support the power supply box 31 and prevent it from swinging in the air and damaging the cable 32.
[0045] In this embodiment, the opening of the receiving slot 201 is oriented so that the power supply box 31 can rise from below into the receiving slot 201. A wire hole 202 is provided at the center of the top wall of the receiving slot 201, through which the cable 32 can pass to connect to the lifting mechanism 10.
[0046] In one embodiment of this implementation, please refer to Figure 4 The storage box 20 has multiple light sources 22 arranged in a circular array around the receiving slot 201. It is understood that the multiple light sources arranged in a circular array around the receiving slot 201 can have a large illumination area and relatively uniform light distribution. Specifically, the light from the light sources 22 is generally directed downwards and tilted outwards relative to the cable 32 to increase the illumination range.
[0047] In one embodiment of this implementation, please refer to Figure 4 The walls of the receiving tank 201 are provided with a cushioning material 21. Specifically, the cushioning material 21 can be a deformable material such as foam, sound-absorbing cotton, or rubber to absorb vibration through deformation. It can be understood that the cushioning material 21 can come into contact with the power supply box 31 and cushion the power supply box 31, preventing the power supply box 31 from having a hard collision with the storage box 20 when it rises, which can effectively reduce noise.
[0048] For further details, please refer to the following: Figure 3 and Figure 9 , Figure 9 yes Figure 3A partial structural diagram of the lifting assembly is provided. The lifting mechanism 10 includes a drive motor 11, a take-up reel 12, and a current sensor (not shown). The drive motor 11 is connected to the take-up reel 12, and the current sensor is used to detect the current value of the drive motor 11. The end of the cable 32 away from the power supply box 31 is wound around the take-up reel 12. The drive motor 11 can drive the take-up reel 12 to rotate, thereby lifting the power supply box 31 into the receiving slot 201 via the cable 32, and causing the power supply box 31 to abut against the cushioning material 21. During the lifting process of the power supply box 31, when the current value detected by the current sensor is greater than or equal to a preset value, the drive motor 11 stops driving.
[0049] It is understandable that as the take-up reel 12 is taking in the cable, as the cable 32 is gradually tightened, the load on the drive motor 11 will gradually increase, and the current value of the drive motor 11 will increase accordingly when the load increases.
[0050] By providing a buffer material 21 on the wall of the receiving groove 201, the buffer material 21 can cushion the power box 31 to reduce noise. At the same time, a current sensor is provided to detect the current value of the drive motor 11. During the rising process of the power box 31, the power box 31 can come into contact with the buffer material 21, and the cable 32 will not be pulled to its maximum tension all at once. The load on the drive motor 11 will increase at a gradual rate, and the current value of the drive motor 11 will also rise slowly. The drive motor 11 can stop driving in time according to the current value detected by the current sensor, so that the power box 31 can be stored in the receiving groove 201 and the cable 32 can be prevented from being torn.
[0051] In one embodiment of this implementation, please refer to Figure 3 and Figure 9 The lifting mechanism 10 includes an encoder 13, which is mounted on the output shaft of the drive motor 11 and is used to detect the angle of rotation of the output shaft.
[0052] In one embodiment of this implementation, please refer to Figure 9 The current sensor is installed on the power supply line of the drive motor 11. With this configuration, the current sensor can obtain the current value of the drive motor 11 in real time, so that the drive motor 11 can receive feedback in time and stop driving.
[0053] In one embodiment of this implementation, please refer to Figure 4The cushioning material 21 includes a first part 211 and a second part 212. The first part 211 abuts against the top surface of the power supply box 31, and the second part 212 abuts against the side surface of the power supply box 31. Specifically, the first part 211 and the second part 212 are both distributed in a ring shape within the groove wall. The first part 211 is located on the top wall of the groove wall, and the second part 212 is located on the side wall of the groove wall, relatively close to the opening of the receiving groove 201. This arrangement can adequately cushion the power supply box 31 and further reduce noise.
[0054] In one embodiment of this implementation, please refer to Figure 2 and Figure 4 The rope hoisting device 100 includes a conduit 40, and the lifting mechanism 10 includes a mounting box 14. A take-up reel 12 is installed inside the mounting box 14, which is used to fix the cable to the top side of the ceiling 200. One end of the conduit 40 is connected to the take-up box 20, and the other end is connected to the mounting box 14. The cable 32 is threaded through the conduit 40. Specifically, the drive motor 11 is also installed inside the mounting box 14. The conduit 40 is connected to the wire hole 202 and can be connected and fixed to the take-up box 20 and the mounting box 14 by means of threaded connection or other methods. By setting up the mounting box 14 and the conduit 40, the cable 32 can be reduced from being exposed to the outside, reducing the risk of damage to the cable 32. At the same time, the conduit 40 can provide a fixed support point for the take-up box 20, allowing the take-up box 20 to be suspended on the bottom side of the ceiling 200.
[0055] In one embodiment of this implementation, please refer to Figure 2 , Figure 6 , Figure 7 and Figure 8 , Figure 6 yes Figure 4 A three-dimensional structural diagram of the power supply component 30; Figure 7 yes Figure 4 An exploded view of the power supply component 30; Figure 8 yes Figure 7 The diagram shows the structure of the power supply assembly 30 within the mounting chamber 3111. The power supply box 31 includes a box body 311 and multiple power modules 312. The box body 311 has a mounting chamber 3111 and multiple first mounting holes 3112 communicating with the mounting chamber 3111. The multiple power modules 312 are detachably mounted in the first mounting holes 3112. Specifically, the power modules 312 can be detachably mounted in the first mounting holes 3112 using methods such as snap-fitting or threaded connections. This design reduces the difficulty of assembling and disassembling the power modules 312, facilitating installation and replacement as needed.
[0056] In this embodiment, please refer to Figure 2 , Figure 6 and Figure 7 The power module 312 is provided with a buckle 31211. The power module 312 can extend into the mounting chamber 3111 from the first mounting hole 3112, so that the buckle 31211 is fastened to the box body 311, and the power module 312 is relatively fixed to the box body 311.
[0057] Specifically, the power module 312 can be a low-voltage DC module, a high-voltage AC module, or other similar modules. A receiving slot 201 is located on the bottom side of the housing 311. By providing a latch 31211 on the power module 312, when the power module 312 extends into the mounting chamber 3111 through the first mounting hole 3112, the latch 31211 can engage with the housing 311, thereby fixing the power module 312 relatively to the housing 311. The installation process eliminates the need for screws or other connectors, effectively reducing the installation difficulty of the power box 31 and improving installation efficiency.
[0058] In one embodiment of this implementation, please refer to Figure 7 The power module 312 includes a mounting plate 3121 and multiple sockets 3122. The sockets 3122 are mounted on the mounting plate 3121, and a latch 31211 is disposed on the mounting plate 3121. There is a gap between the mounting plate 3121 and the inner wall of the first mounting hole 3112. It is understood that by creating a gap between the mounting plate 3121 and the inner wall of the first mounting hole 3112, students or workers can easily insert their hands or tools such as screwdrivers into the gap and push and squeeze the latch 31211 to disengage it from the housing 311, and then remove the power module 312 from the housing 311. This design makes disassembling the power module 312 easier, allowing students to replace different types of power modules 312 according to different experimental needs.
[0059] In one embodiment of this implementation, please refer to Figure 7 and Figure 8 An annular protrusion 31121 is formed on the inner wall of the first mounting hole 3112, and the annular protrusion 31121 abuts against the bottom surface of the mounting plate 3121. With this configuration, the annular protrusion 31121 can better support the mounting plate 3121, making the connection between the power module 312 and the housing 311 more stable, and the housing 311 can better withstand the force when the socket 3122 is used to insert the wire.
[0060] In one embodiment of this implementation, please refer to Figure 7 and Figure 8The annular protrusion 31121 has a notch 31122, and the inner wall of the mounting chamber 3111 has a correspondingly protruding fastening plate 31111. The buckle 31211 extends into the mounting chamber 3111 through the notch 31122 and engages with the fastening plate 31111. By creating the notch 31122 on the annular protrusion 31121 to allow the buckle 31211 to extend into the mounting chamber 3111, and by providing the correspondingly protruding fastening plate 31111 on the inner wall of the mounting chamber 3111, the buckle 31211 can engage with the fastening plate 31111 to achieve installation. On the other hand, the buckle 31211 has a larger length so that it can be disengaged from the fastening plate 31111 under the action of external force, further reducing the difficulty of disassembly.
[0061] In one embodiment of this implementation, please refer to Figure 7 and Figure 8 There are multiple clips 31211, notches 31122, and fastening plates 31111. Multiple clips 31211 extend into the mounting cavity 3111 from the corresponding notches 31122 and engage with the corresponding fastening plates 31111. This arrangement ensures a high connection strength between the power module 312 and the housing 311.
[0062] In this embodiment, each power module 312's mounting plate 3121 is provided with four buckles 31211, the annular protrusion 31121 has four notches 31122 at corresponding positions, and the mounting chamber 3111 has four fastening plates 31111 at corresponding positions. The four buckles 31211 extend into the mounting chamber 3111 from the corresponding notches 31122 and are fastened to the corresponding fastening plates 31111.
[0063] In one embodiment of this implementation, please refer to Figure 1 , Figure 6 and Figure 7 The power module 312 is mounted on the periphery of the housing 311, and the distance sensor 33 is mounted on the bottom side of the housing 311. Both the power module 312 and the distance sensor 33 are electrically connected to the cable 32. Specifically, the first mounting hole 3112 is formed on the periphery of the housing 311. This arrangement makes full use of the space in the housing 311 to install the power module 312 and the distance sensor 33, facilitates the distance sensor 33 in obtaining the distance between the housing 311 and the reference surface 300, and allows student users to connect the power module 312 to the experimental equipment.
[0064] In one embodiment of this implementation, please refer to Figure 2 , Figure 6 and Figure 7The casing 311 has multiple first mounting holes 3112 communicating with the mounting chamber 3111 on its periphery. Multiple power modules 312 are respectively installed in the corresponding first mounting holes 3112 and extend into the mounting chamber 3111. In this embodiment, the casing 311 has four first mounting holes 3112, and four power modules 312 are installed in their respective first mounting holes 3112. This arrangement allows the power modules 312 to be installed from the periphery of the casing 311, making installation and power connection convenient.
[0065] In one embodiment of this implementation, please refer to Figure 5 and Figure 7 The bottom side of the housing 311 has a second mounting hole 3113 communicating with the mounting chamber 3111. The distance sensor 33 is mounted in the mounting chamber 3111, and at least partially located within the second mounting hole 3113. Specifically, the distance sensor 33 is fixed in the mounting chamber 3111 by screws. There are two second mounting holes 3113; the transmitting end of the signal transmitter 331 is located in one of the second mounting holes 3113, and the receiving end of the signal receiver 332 is located in the other second mounting hole 3113. With this configuration, the distance sensor 33 is mostly located within the mounting chamber 3111, making it less susceptible to damage, and it can communicate with the outside world through the second mounting hole 3113 for distance detection.
[0066] In one embodiment of this implementation, please refer to Figure 9 The take-up reel 12 has an annular groove 121, the width of which is the same as the diameter of the cable 32. The cable 32 is wound around the annular groove 121. This arrangement ensures a relatively stable correspondence between the rotation angle of the output shaft and the take-up length of the cable 32, guaranteeing that the length of the cable unwound is consistent each time the rotation angle of the output shaft remains unchanged, thus reducing errors.
[0067] Please see Figure 1 This invention also provides a teaching system, which includes a multi-functional demonstration stand (not shown) and a rope hoisting device 100 of this invention. Multiple rope hoisting devices 100 are provided, and their lifting mechanisms 10 are electrically connected to the multi-functional demonstration stand. The multi-functional demonstration stand sends control signals to the lifting mechanisms 10, which then drive the power supply box 31 to rise and fall according to the control signals. Specifically, the multi-functional demonstration stand is connected to the drive motors 11 in the multiple lifting mechanisms 10, allowing control of the drive motors 11 to release or retract the cable. By incorporating the rope hoisting device 100 of this invention into the teaching system, the power supply box 31 can be maintained at a suitable height for student experiments. Furthermore, the teaching system requires no complex debugging before use, reducing service costs.
