Description

Technical Field

[0001] This disclosure relates to the technical field of electrical control training and assessment, and more specifically, to an electrical control training device. Background Technology

[0002] Electrical control training and assessment devices are core equipment used in vocational education and skills training for practical training and competency assessment related to electrical control. They typically integrate general-purpose modules such as power supply, safety protection, and measurement display to meet various experimental operation needs, as well as specialized modules adapted to different specialized experiments such as motor control, PLC programming, and frequency converter speed regulation, providing trainees with a complete training scenario from basic wiring to complex system debugging. With the diversification of practical training content, devices corresponding to a single training project are no longer sufficient to meet the needs of multi-skill training. Existing devices often use multiple independent training platforms to carry different modules, or fix general-purpose and specialized modules within the same device, resulting in a module layout that cannot be flexibly adjusted according to training projects and wiring requirements.

[0003] The positions of general-purpose and special-purpose modules are relatively fixed. When training circuits require cross-module wiring, the mismatch between module spacing and wire length leads to problems such as short wires failing to connect effectively and long wires becoming tangled and messy, affecting the smoothness of training operations and circuit stability. Different training projects have different requirements for module combinations, and a fixed layout is difficult to adapt to diverse combination scenarios. Multiple additional training devices are needed to cover all teaching content, which not only increases teaching costs but also occupies a large amount of training space. Summary of the Invention

[0004] To address at least one of the technical problems in the prior art, embodiments of this disclosure provide an electrical control training device capable of adjusting the spacing between multiple electrical modules.

[0005] This disclosure provides an electrical control training device, comprising: a support cabinet; and a training box, wherein the training box has an opening on its side and has multiple accommodating spaces inside, the training box comprising: a pair of limiting plates disposed on the front side of each of the accommodating spaces, the pair of limiting plates including a first limiting plate and a second limiting plate arranged parallel to the first limiting plate along the width direction of the training box at a distance from the first limiting plate; a limiting rail disposed on the rear side of each of the accommodating spaces opposite to the front side along the depth direction of the training box, the limiting rail being located between the first limiting plate and the second limiting plate and extending along the length direction of the training box; and at least one electrical module, the front side of each electrical module being slidably disposed between the first limiting plate and the second limiting plate, and the rear side of each electrical module being slidably engaged with the limiting rail to adjust the spacing between the multiple electrical modules.

[0006] According to some embodiments of this disclosure, a plurality of the aforementioned accommodating spaces are arranged in parallel at intervals along the width direction of the aforementioned training box and extend along the aforementioned depth direction. The aforementioned first limiting plate and the aforementioned second limiting plate each include: a mounting portion, which is mounted on the front side of the aforementioned accommodating space; and a limiting portion, which extends from one side of the aforementioned mounting portion perpendicularly to the plane where the aforementioned mounting portion is located toward the direction close to the aforementioned electrical module.

[0007] According to some embodiments of this disclosure, each of the above-mentioned electrical modules includes: a housing, with two outer extension plates extending vertically away from the housing from the front side and opposite sides along the width direction, the two outer extension plates slidingly engaging with the limiting portion of the first limiting plate and the limiting portion of the second limiting plate; and two limiting mechanisms respectively disposed between the mounting portion of the first limiting plate and the housing, and between the mounting portion of the second limiting plate and the housing, each of the limiting mechanisms being configured to have a locking state in contact with the mounting portion and an open state separated from the mounting portion.

[0008] According to some embodiments of this disclosure, a first groove is provided on the surface of the housing facing the mounting portion of the first limiting plate and the surface of the housing facing the mounting portion of the second limiting plate. A plurality of spaced limiting holes are provided on the side of the mounting portion facing the rear side of the accommodating space. Each limiting mechanism includes: a first slide rod, one end of which is connected to the extension plate, and the other end of which is connected to the side of the first groove facing the extension plate; a first sliding plate, one end of which is slidably disposed on the first slide rod; and a pressing rod, one end of which passes through the extension plate and is connected to one end of the first sliding plate, so as to push the first sliding plate along the depth direction under the action of an external force, causing the other end of the first sliding plate to separate from the limiting hole, forming the open state.

[0009] According to some embodiments of this disclosure, the other end of the first sliding plate extends in a direction perpendicular to the plane where the first sliding plate is located toward the limiting hole to form a first protrusion, so as to engage with the limiting hole.

[0010] According to some embodiments of this disclosure, each of the aforementioned limiting mechanisms further includes: a first elastic member, one end of which abuts against one end of the first sliding plate, and the other end of which is connected to the side of the first groove facing the extension plate. The first elastic member is configured to compress in response to the pressing rod pushing the first sliding plate along the depth direction, and to reset and push the first sliding plate when the first protrusion is aligned with the limiting hole, such that the first protrusion is inserted into the limiting hole along the depth direction, forming the locking state.

[0011] According to some embodiments of this disclosure, each of the above-mentioned electrical modules further includes: a frame, which is retractably disposed within the housing, the frame being adapted to accommodate a functional module; and two sets of locking mechanisms, respectively disposed on opposite sides of the frame along the length direction, and having a disengaged state that allows the frame to slide relative to the housing along the depth direction, and a locked state that restricts the frame within the housing.

[0012] According to some embodiments of this disclosure, the housing is provided with toothed portions on two opposing sides along the length direction. Each set of the locking mechanism includes: a locking plate, the first side of which is rotatably mounted on the side of the frame facing the housing, and the second side of which is opposite to the first side along the depth direction engages with the toothed portion; and a second slide rod, which extends along the depth direction and one end of which is slidably connected to the side of the locking plate facing the frame. The second slide rod is configured to move along the depth direction under the action of an external force to move the second side of the locking plate away from the toothed portion, forming the disengaged state, or to move the second side of the locking plate closer to the toothed portion and engage with the toothed portion, forming the engaged state.

[0013] According to some embodiments of this disclosure, each set of the above-mentioned snap-fit ​​mechanisms further includes: at least one fixing plate, installed on the side of the frame facing the housing, the fixing plate having a through hole to allow the other end of the second slide rod to pass through; a second elastic member, sleeved on the outside of the second slide rod, one end of the second elastic member being connected to the fixing plate; and a push plate, installed on the second slide rod and connected to the other end of the second elastic member, so as to move along the depth direction towards the fixing plate under the drive of the second slide rod and compress the second elastic member.

[0014] According to some embodiments of this disclosure, the limiting track is provided with a plurality of second grooves arranged parallel to the length direction. Each electrical module further includes: a sliding frame that slides with the limiting track, wherein two surfaces facing each other in the width direction within the sliding frame extend in a direction perpendicular to the surface of the sliding frame and approach each other to form a baffle; at least one third slide rod, one end of which is connected to the baffle and the other end of which is connected to the side of the sliding frame facing the limiting track; a second sliding plate that is slidably disposed on the third slide rod, and the surface of the second sliding plate facing the limiting track has a second protrusion that engages with the second groove; and at least one third elastic member that is sleeved on the outside of the third slide rod, one end of which is connected to the side of the sliding frame facing the limiting track and the other end of which abuts against the second sliding plate to prevent the second sliding plate from sliding along the depth direction on the third slide rod when the second protrusion engages with the second groove.

[0015] According to the electrical control training device of this disclosure, the front side of the electrical module is slidably disposed between a pair of limiting plates fixed to the front side of the accommodating space, thereby constraining the electrical module in the width direction of the training box. By slidingly engaging the rear side of the electrical module with a limiting track fixed to the rear side of the accommodating space along the length direction of the training box, the sliding of the electrical module is restricted to the length direction of the training box. This ensures the straightness and stability of the sliding trajectory of the electrical module, allowing trainees to flexibly adjust the spacing between multiple electrical modules along the length direction to adapt to the module layout and wire length requirements of different training circuits.

[0079] Figure 1 This is a perspective view of an electrical control training device according to an illustrative embodiment of the present disclosure. Figure 2 This is a partial cross-sectional perspective view of a training box according to an illustrative embodiment of the present disclosure. Figure 3 This is a perspective view of a training box according to an illustrative embodiment of the present disclosure.

[0080] An electrical control training device is provided according to an embodiment of this disclosure, such as... Figure 1 , Figure 2 and Figure 3 As shown, the electrical control training device includes a support cabinet 1 and a training box 2. The training box 2 has an opening on its side and multiple accommodating spaces inside. The training box 2 includes a pair of limiting plates, limiting rails 23, and at least one electrical module 24. A pair of limiting plates are located on the front side of each accommodating space. The pair of limiting plates includes a first limiting plate 21 and a rail along the width direction of the training box 2 (e.g., along the first limiting plate 21). Figure 2 The second limiting plates 22 are arranged parallel to each other at intervals in the Z direction shown in the diagram. Limiting rails 23 are provided in each accommodating space along the depth direction of the front side of the training box 2 (e.g., in the Z direction). Figure 2 On the opposite rear side (as shown in the Y direction), the limiting track 23 is located between the first limiting plate 21 and the second limiting plate 22, and along the length direction of the training box 2 (as shown in the Y direction). Figure 2 (Extended in the X direction shown). The front side of each electrical module 24 is slidably disposed between the first limiting plate 21 and the second limiting plate 22, and the rear side of each electrical module 24 is slidably engaged with the limiting track 23 to adjust the spacing between the plurality of electrical modules 24.

[0081] In some illustrative embodiments, the cross-section of the training box 2 is trapezoidal, and the front end face of the training box 2 is inclined to facilitate operation by trainees.

[0082] In some illustrative embodiments, the two ends of the first limiting plate 21 and the second limiting plate 22, which are opposite each other along the length direction, are fixedly connected to the front side of the training box 2.

[0083] In some illustrative embodiments, each electrical module 24 includes a dedicated module adapted for different specialized experiments such as motor control, PLC programming, and frequency converter speed regulation.

[0084] In some illustrative embodiments, multiple general-purpose modules 30 can be arranged below the electrical module 24 in the training box 2. As an example, the general-purpose module 30 includes an AC power supply module, a DC voltage regulator module, a safety protection module, and a signal acquisition module. Each general-purpose module 30 is equipped with an independent power switch and a working status indicator light, and the output parameter labels are clearly marked on the surface of the general-purpose module 30.

[0085] Specifically, external wiring is required between the dedicated module and the general module 30. This connection mode, which requires all external wiring, allows trainees to fully participate in the entire process from module mounting to circuit construction. Trainees need to independently determine the wiring logic between the dedicated module and the general module 30, select the appropriate wire specifications, and complete the terminal connections. Compared to traditional devices with pre-installed circuits, this better simulates the real-world wiring scenarios of industrial field equipment.

[0086] In some illustrative embodiments, a plurality of first heat dissipation holes 200 are arranged at intervals along the length of each accommodating space on the rear side to facilitate heat dissipation of the electrical module 24.

[0087] In this implementation, the electrical module 24 is slidably positioned between a pair of limiting plates fixed to the front of the accommodating space, thus constraining the electrical module 24 in the width direction of the training box 2. By sliding the rear of the electrical module 24 into a limiting track 23 fixed to the rear of the accommodating space along the length direction of the training box 2, the sliding of the electrical module 24 is restricted to the length direction of the training box 2. This ensures the straightness and stability of the sliding trajectory of the electrical module 24, allowing trainees to flexibly adjust the relative positions of each electrical module 24 within the accommodating space along the length direction. The spacing between multiple electrical modules 24 can be adjusted according to the wire length, avoiding the problem of short wires being unable to connect, thereby adapting to the module layout and wire length requirements of different training circuits.

[0088] According to embodiments of this disclosure, such as Figure 1 , Figure 2 and Figure 3 As shown, multiple accommodating spaces are arranged parallel to each other at intervals along the width direction of the training box 2 and extend along the depth direction. The first limiting plate 21 and the second limiting plate 22 both include a mounting part 210 and a limiting part 211. The mounting part 210 is mounted on the front side of the accommodating space. The limiting part 211 extends from one side of the mounting part 210 perpendicularly to the plane where the mounting part 210 is located towards the electrical module 24.

[0089] In some illustrative embodiments, multiple accommodating spaces are arranged in parallel at intervals along the width direction and extend along the depth direction, each accommodating space being constructed as a generally elongated groove.

[0090] In some illustrative embodiments, the limiting portion 211 bends or extends from one side of the mounting portion 210 perpendicular to the plane where the mounting portion 210 is located toward the electrical module 24, presenting a flange with a cross-section that is approximately L-shaped.

[0091] In this embodiment, by extending the limiting part 211 vertically from the mounting part 210 toward the electrical module 24, a guide plane or contact surface parallel to and adjacent to the side of the front frame of the electrical module 24 is formed. This allows the electrical module 24 to slide along its length direction, with the two opposite sides of the front side of the electrical module 24 in the width direction maintaining sliding contact with the limiting part 211 of the first limiting plate 21 and the limiting part of the second limiting plate 22, respectively. This restricts the degree of freedom of the electrical module 24 in the width direction, ensuring that the sliding process of the electrical module 24 is smooth and without shaking. At the same time, together with the limiting track 23 on the rear side, it forms a sliding support for the front and rear sides of the electrical module 24, achieving motion stability when the spacing of the electrical module 24 is adjusted.

[0092] According to embodiments of this disclosure, each electrical module 24 includes a housing 241 and two limiting mechanisms. Extending plates 2410 are formed on the front side of the housing 241 and on opposite sides along its width, extending vertically away from the housing 241. The two extending plates 2410 are slidably engaged with the limiting portion 211 of the first limiting plate 21 and the limiting portion of the second limiting plate 22, respectively. The two limiting mechanisms are respectively disposed between the mounting portion 210 of the first limiting plate 21 and the housing 241, and between the mounting portion of the second limiting plate 22 and the housing 241. Each limiting mechanism is configured to have a locked state in contact with the mounting portion 210 and an open state separated from the mounting portion 210.

[0093] In this implementation, the use of two limiting mechanisms effectively prevents the housing 241 from shifting due to accidental contact with a single limiting mechanism. The outer extension plates 2410 on the front side of the housing 241, facing each other along the width direction, maintain a sliding engagement with the limiting portions 211 of the first limiting plate 21 and the second limiting plate 22, respectively, thus constraining the electrical module 24's degree of freedom in the width direction. Each limiting mechanism is configured to have a locked state in contact with the mounting portion 210 and an open state separated from the mounting portion 210, thereby constraining the electrical module 24's degree of freedom in the depth direction when it slides to the target position. This restricts the sliding of the electrical module 24 to the length direction of the training box 2, ensuring the straightness and stability of the electrical module 24's sliding process.

[0094] Figure 4 This is a perspective view of an electrical module according to an illustrative embodiment of the present disclosure. Figure 5 yes Figure 4 Partial sectional perspective view in the CC direction. Figure 6 yes Figure 5 A magnified view of a portion of point A in the middle.

[0095] According to embodiments of this disclosure, such as Figure 4 , Figure 5 and Figure 6 As shown, the housing 241 has a first groove 2411 on both the surface of the mounting portion 210 facing the first limiting plate 21 and the surface of the mounting portion facing the second limiting plate 22. The mounting portion 210 has multiple spaced limiting holes 212 on its side facing the rear of the accommodating space. Each limiting mechanism includes a first sliding rod 242, a first sliding plate 243, and a pressing rod 244. One end of the first sliding rod 242 is connected to the extension plate 2410, and the other end is connected to the side of the first groove 2411 facing the extension plate 2410. One end of the first sliding plate 243 is slidably disposed on the first sliding rod 242. One end of the pressing rod 244 passes through the extension plate 2410 and connects to one end of the first sliding plate 243, so that under external force, it pushes the first sliding plate 243 along the depth direction, causing the other end of the first sliding plate 243 to separate from the limiting hole 212, forming an open state.

[0096] In this embodiment, one end of the first slide rod 242 is connected to the extension plate 2410, and the other end of the first slide rod 242 is connected to the side of the first groove 2411 facing the extension plate 2410, which can provide a guiding effect along the depth direction for the sliding of the first sliding plate 243. By fixing one end of the pressing rod 244 to the first sliding plate 243, an external force applied to the front end of the pressing rod 244 in the depth direction can directly drive the first sliding plate 243 to slide synchronously in the depth direction on the first slide rod 242. At this time, the other end of the first sliding plate 243 separates from the limiting hole 212, thereby releasing the interlock and forming an open state, allowing the housing 241 to slide along the length direction, realizing the switching and stable maintenance of the locked and open states of the electrical module 24.

[0097] According to embodiments of this disclosure, such as Figure 6 As shown, the other end of the first sliding plate 243 extends along the plane perpendicular to the first sliding plate 243 toward the limiting hole 212 to form a first protrusion 2430, so as to cooperate with the limiting hole 212.

[0098] According to embodiments of this disclosure, each limiting mechanism further includes a first elastic member 245. One end of the first elastic member 245 abuts against one end of the first sliding plate 243, and the other end of the first elastic member 245 is connected to the side of the first groove 2411 facing the extension plate 2410. The first elastic member 245 is configured to compress in response to the pressing rod 244 pushing the first sliding plate 243 in the depth direction, and to reset by pushing the first sliding plate 243 when the first protrusion 2430 is aligned with the limiting hole 212, such that the first protrusion 2430 is inserted into the limiting hole 212 in the depth direction, forming a locking state.

[0099] Specifically, when the position of the electrical module 24 needs to be adjusted, the pressing rod 244 is pressed along the depth direction. The pressing rod 244 pushes the first sliding plate 243 along the depth direction, and the first sliding plate 243 moves backward along the depth direction, causing the first protrusion 2430 to disengage from the limiting hole 212 at the current position, forming an open state. At this time, the two outer plates 2410 of the front side of the electrical module 24, i.e., the housing 241, can slide and engage with the limiting part 211 of the first limiting plate 21 and the limiting part of the second limiting plate 22, respectively, and the rear side of the electrical module 24 can slide and engage with the limiting track 23.

[0100] After the electrical module 24 is moved to the target position, the pressing rod 244 is released. The first sliding plate 243 moves forward along the depth direction under the elastic force of the first elastic element 245. The first protrusion 2430 is aligned with the limiting hole 212 at the target position and is inserted into the limiting hole 212 along the depth direction to form a locking state, thereby realizing the precise adjustment of the position of the electrical module 24.

[0101] Figure 7 yes Figure 4 Partial sectional perspective view in the DD direction.

[0102] According to embodiments of this disclosure, such as Figure 7 As shown, each electrical module 24 also includes a frame 246 and two sets of latching mechanisms 247. The frame 246 is retractably disposed within the housing 241, and the frame 246 is adapted to accommodate the functional module 252. The two sets of latching mechanisms 247 are respectively disposed on opposite sides of the frame 246 along the length direction, and have a disengaged state that allows the frame 246 to slide relative to the housing 241 along the depth direction, and an engaged state that restricts the frame 246 within the housing 241.

[0103] In some illustrative embodiments, functional module 252 includes dedicated modules adapted to different specialized experiments such as motor control, PLC programming, and frequency converter speed regulation.

[0104] Specifically, the dedicated module is equipped with electrical connection sockets 2520. Multiple electrical connection sockets 2520 of the same specification are provided, but the front port shapes of different specifications of electrical connection sockets 2520 are different. Due to the shape differences of the electrical connection sockets 2520 on the dedicated module, adapter wires are selected to electrically connect the dedicated module to the general module 30. The irregular design of the different specifications of the electrical connection sockets 2520 can avoid incorrect connections, reduce the risk of circuit failures caused by specification confusion, and ensure the standardized connection of the training circuit.

[0105] In some illustrative embodiments, the frame 246 has gaps between its opposite sides along its length and the housing 241 to accommodate the snap-fit ​​mechanism 247.

[0106] In some illustrative embodiments, such as Figure 4and Figure 5 As shown, ventilation slots are provided on the opposite sides of the frame 246 along its width direction, and multiple second heat dissipation holes 2460 are provided on the opposite sides of the frame 246 along its width direction. Multiple third heat dissipation holes 2413 are provided on the opposite sides of the housing 241 along its width direction, at positions corresponding to the multiple second heat dissipation holes 2460, and the multiple second heat dissipation holes 2460 communicate with the multiple third heat dissipation holes 2413. The airflow channel formed by the multiple first heat dissipation holes 200, the multiple second heat dissipation holes 2460, and the multiple third heat dissipation holes 2413 allows for air circulation in each functional module 252, achieving better heat dissipation for each functional module 252.

[0107] In this implementation, the use of two sets of locking mechanisms 247 effectively prevents the housing 241 from shifting due to accidental contact of a single locking mechanism 247. The two sets of locking mechanisms 247 have an engaged state that confines the frame 246 within the housing 241, preventing the frame 246 from slipping out due to vibration or pulling during training. The two sets of locking mechanisms 247 also have a disengaged state that allows the frame 246 to slide relative to the housing 241 along the depth direction. In this state, the constraint between the frame 246 and the housing 241 in the depth direction is released, allowing the frame 246 to slide smoothly out or be pushed in along the depth direction. The engagement and disengagement states enable switching between engagement and disengagement of the frame 246 within the housing 241, facilitating the replacement and maintenance of the functional module 252, while ensuring the stability of the functional module 252 during training operations.

[0108] Figure 8 This is a partial perspective view of the locking plate and the second slide bar according to an illustrative embodiment of the present disclosure.

[0109] According to embodiments of this disclosure, the housing 241 has toothed portions 2412 on two opposing sides along its length, and each set of engaging mechanisms 247 includes an engaging plate 2471 and a second slide bar 2472. For example... Figure 7 and Figure 8 As shown, the first side of the engaging plate 2471 is rotatably mounted on the side of the frame 246 facing the housing 241, and the second side of the engaging plate 2471, which is opposite to the first side along the depth direction, engages with the toothed portion 2412. The second slide rod 2472 extends along the depth direction, and one end of the second slide rod 2472 is slidably connected to the side of the engaging plate 2471 facing the frame 246. The second slide rod 2472 is configured to move along the depth direction under the action of an external force, so as to drive the second side of the engaging plate 2471 away from the toothed portion 2412 to form a disengaged state, or to drive the second side of the engaging plate 2471 closer to the toothed portion 2412 and engage with the toothed portion 2412 to form an engaged state.

[0110] In some illustrative embodiments, the locking plate 2471 has a groove 2476 along the depth direction on the side facing the frame 246, and a limiting slider 2477 is slidably connected in the groove 2476. The limiting slider 2477 is hinged to one end of the second sliding rod 2472.

[0111] In some illustrative embodiments, the second side of the locking plate 2471 is provided with toothed protrusions that engage with the toothed portion 2412. When the second slide rod 2472 moves along the depth direction under the action of external force and drives the second side of the locking plate 2471 to approach the toothed portion 2412, it engages with the toothed portion 2412 to form a locking state, which can restrict the frame 246 within the housing 241 and ensure the stability of the functional module 252 within the housing 241.

[0112] In this implementation, the movement of the second slide rod 2472 along the depth direction is converted into the rotation of the engaging plate 2471 via the slide groove 2476 and the limiting slider 2477 slidably connected to the slide groove 2476. This efficiently converts the linear force on the second slide rod 2472 into the engagement and disengagement of the engaging plate 2471 and the toothed portion 2412, thereby achieving a quick and effortless switching between the engaging and disengaged states. The housing 241 has continuous toothed portions 2412 on two opposing sides along its length, providing multiple selectable engagement positions for the sliding stroke of the frame 246 within the housing 241. This allows trainees to adjust the extended length of the frame 246 according to the size of the functional module 252 or wiring requirements.

[0113] Figure 9 This is a partial perspective view of an electrical module according to an illustrative embodiment of the present disclosure, showing the frame, functional modules, and snap-fit ​​mechanism. Figure 10 yes Figure 9 A magnified view of a section at point B.

[0114] According to embodiments of this disclosure, such as Figure 9 and Figure 10 As shown, each set of locking mechanisms 247 further includes at least one fixing plate 2473, a second elastic element 2474, and a push plate 2475. At least one fixing plate 2473 is mounted on the side of the frame 246 facing the housing 241, and a through hole is provided on the fixing plate 2473 to allow the other end of the second slide rod 2472 to pass through. The second elastic element 2474 is sleeved on the outside of the second slide rod 2472, and one end of the second elastic element 2474 is connected to the fixing plate 2473. The push plate 2475 is mounted on the second slide rod 2472 and connected to the other end of the second elastic element 2474, so that it moves along the depth direction towards the fixing plate 2473 under the action of the second slide rod 2472, and compresses the second elastic element 2474.

[0115] In some illustrative embodiments, each set of latching mechanisms 247 includes at least one fixing plate 2473. As an example, two fixing plates 2473 are provided at intervals along the depth direction on the side of the frame 246 facing the housing 241. Both fixing plates 2473 are provided with through holes to allow the other end of the second slide bar 2472 to pass through.

[0116] Specifically, when it is necessary to adjust the position of the frame 246 containing the functional module 252 within the housing 241, the second slide bar 2472 is moved rearward along the depth direction. Driven by the second slide bar 2472, the push plate 2475 moves towards the fixed plate 2473 along the depth direction and compresses the second elastic member 2474. At the same time, one end of the second slide bar 2472 slides rearward along the depth direction within the slide groove 2476 through the limiting slider 2477. The first side of the locking plate 2471 rotates, and at this time, the second side of the locking plate 2471 moves away from the toothed part 2412, forming a disengaged state, which allows the position of the frame 246 within the housing 241 to be adjusted. After the adjustment is completed, the second slide bar 2472 is released. The push plate 2475 moves away from the fixed plate 2473 along the depth direction under the drive of the second slide bar 2472, so that the second elastic element 2474 is reset. At the same time, one end of the second slide bar 2472 slides forward along the depth direction in the slide groove 2476 through the limiting slider 2477. The first side of the locking plate 2471 rotates. At this time, the second side of the locking plate 2471 approaches the toothed part 2412 and engages with the toothed part 2412 to form a locking state, which restricts the frame 246 in the housing 241.

[0117] In this implementation, the linear force on the second slide bar 2472 is efficiently converted into the engagement and disengagement of the engagement plate 2471 and the toothed part 2412, thereby achieving a quick and effortless switch between the engagement and disengagement states. No special tools are required, and trainees can quickly adjust the position of the frame 246 within the housing 241 or replace functional modules, improving the switching efficiency of training projects.

[0118] According to an embodiment of the present disclosure, a dustproof plate 28 is provided between two adjacent electrical modules 24. The dustproof plate 28 is constructed in a corrugated shape, and the two sides of the dustproof plate 28 are respectively connected to the outer wall of the housing 241 of the two adjacent electrical modules 24.

[0119] Specifically, each accommodating space is provided with two guide rods 29 on its front side. The two guide rods 29 are arranged parallel to each other at intervals along the width direction of the accommodating space, and both guide rods 29 extend along the length direction. The two guide rods 29 pass through the opposite sides of the dustproof plate 28 along the width direction, and each guide rod 29 passes between the limiting part 211 and the first sliding plate 243 of each electrical module 24. The two guide rods 29 not only provide guidance for the sliding of the dustproof plate 28 along the length direction, but also maintain the stability of the dustproof plate 28 during the sliding process.

[0120] In this implementation, as the electrical module 24 slides along its length, the dustproof plate 28 extends and retracts synchronously with the positions of the two adjacent electrical modules 24, always keeping the accommodating space closed and effectively preventing dust from entering the accommodating space.

[0121] Figure 13 This is a perspective view of a connecting frame and an operation screen according to an illustrative embodiment of the present disclosure.

[0122] According to embodiments of this disclosure, such as Figure 1 and Figure 13 As shown, a roughly U-shaped connecting frame 27 is fixedly connected to the outside of the training box 2. A connecting ring 261 is fitted onto the connecting frame 27, and the operation screen 26 is fixedly connected to the connecting frame 27 via the connecting ring 261. A rubber pad can be placed between the connecting ring 261 and the connecting frame 27. Rotating the connecting ring 261 will adjust the height of the operation screen 26 along the U-shaped connecting frame 27. The damping effect of the rubber pad can stably fix the operation screen 26 at any height, thus meeting the practical needs of trainees.

[0123] Figure 11 yes Figure 4 Cross-sectional view in the DD direction, Figure 12 This is a partial perspective view of an electrical module according to an illustrative embodiment of the present disclosure, showing a sliding frame, a third sliding rod, a second sliding plate, and a third elastic member.

[0124] According to embodiments of this disclosure, such as Figure 11 and Figure 12As shown, the limiting track 23 is provided with a plurality of second grooves 231 arranged parallel to each other along the length direction. Each electrical module 24 also includes a sliding frame 248, at least one third sliding rod 249, a second sliding plate 250, and at least one third elastic element 251. The sliding frame 248 is slidably engaged with the limiting track 23. Two surfaces facing each other along the width direction inside the sliding frame 248 extend in a direction perpendicular to the surface of the sliding frame 248 and approach each other to form a baffle 2480. One end of the third sliding rod 249 is connected to the baffle 2480, and the other end of the third sliding rod 249 is connected to the side of the sliding frame 248 facing the limiting track 23. The second sliding plate 250 is slidably disposed on the third sliding rod 249, and the surface of the second sliding plate 250 facing the limiting track 23 has a second protrusion 2500 to engage with the second grooves 231. The third elastic member 251 is sleeved on the outside of the third slide rod 249, and one end of the third elastic member 251 is connected to the side of the sliding frame 248 facing the limiting track 23. The other end of the third elastic member 251 abuts against the second sliding plate 250 so as to prevent the second sliding plate 250 from sliding along the depth direction on the third slide rod 249 when the second protrusion 2500 and the second groove 231 are in concave-convex cooperation.

[0125] In some illustrative embodiments, the cross-section of the limiting track 23 is approximately T-shaped, and the limiting track 23 extends into the sliding frame 248 on both opposite sides along the width direction, and slides in cooperation with the sliding frame 248 disposed on the rear side of the housing 241 (the side facing the limiting track 23).

[0126] After the electrical module 24 slides to the target position, the second protrusion 2500 engages with the second groove 231. At this time, under the elastic force of the third elastic member 251, the second sliding plate 250 ensures that the second protrusion 2500 is always located in the second groove 231, thereby ensuring the stability of the electrical module 24.

[0127] Referring to the above structure, during use, select the required functional module 252 according to the training content, insert the frame 246 on the outside of the functional module 252 into the housing 241, and under the action of the second elastic member 2474, push the locking plate 2471 to engage with the toothed part 2412 to achieve a stable connection between the frame 246 and the housing 241. When it is necessary to adjust the spacing between adjacent electrical modules 24 to adapt to the wire length, press the pressing rod 244 along the depth direction. The pressing rod 244 drives the first sliding plate 243 to move backward, so that the first protrusion 2430 disengages from the limiting hole 212, and the housing 241 can be pushed to slide along the limiting track 23. After reaching the target position, release the pressing rod 244, and the first protrusion 2430 is inserted into the corresponding limiting hole 212 under the elastic force of the first elastic member 245, thereby achieving precise position adjustment.

[0128] During the sliding process, the second protrusion 2500, with a V-shaped cross-section, slides out of the second groove 231 along the inner wall of the second groove 231. When it moves to the next position of the second groove 231, the third elastic member 251 pushes the second protrusion 2500 back into the second groove 231, cooperating with the two limiting mechanisms to achieve dual positioning of the housing 241 of the electrical module 24. At the same time, the dustproof plate 28 extends and retracts synchronously with the positions of the two adjacent electrical modules 24, always maintaining the closure of the accommodating space.

[0129] During wiring, according to the different shapes of the electrical connection sockets 2520 of the dedicated modules, select the appropriate wires to connect with the general module 30. The irregular design of the electrical connection sockets 2520 of different specifications can avoid incorrect connection and ensure the connection of the training circuit is standardized. According to the height or operating habits of the trainees, rotating the connecting ring 261 can drive the operating screen 26 to adjust its height along the U-shaped connecting frame 27. The damping effect of the rubber pad can make the operating screen 26 stably fixed at any height, thus meeting the practical needs of the trainees.

[0130] During disassembly, press the second slide bar 2472 backward along the depth direction. The second slide bar 2472 drives the push plate 2475 to move backward. Then, through the cooperation of the limiting slider 2477 and the slide groove 2476, the locking plate 2471 is disengaged from the toothed part 2412. At this time, the frame 246 and the internal special module can be taken out, thus reserving space for the installation of the next set of modules.
