Description

Technical Field

[0001] This utility model relates to the field of low-voltage fast networking technology, and in particular to an expandable low-voltage fast networking device with a multi-load access cabinet. Background Technology

[0002] The mobile power supply vehicle is equipped with a power distribution network that combines primary, secondary, and tertiary power distribution cabinets, providing an efficient and reliable solution for emergency power supply on site. Each primary power distribution cabinet can connect multiple cabinets in parallel, supporting the connection of three secondary power distribution cabinets and nine tertiary power distribution cabinets to form a flexible power distribution system. This design is particularly suitable for emergency situations such as natural disasters and accident sites, enabling rapid restoration of power supply. To ensure the normal operation of rescue equipment and lighting facilities, the equipped digital current and voltage display meters make power monitoring more intuitive, improving the overall system's safety and stability.

[0003] In rainy weather and on muddy roads, typical multi-load access cabinets are prone to water seepage due to a lack of effective protective measures in their design. This can lead to dampness and leakage of the equipment, and in severe cases, even electric shock. Muddy ground also makes the multi-load access cabinets prone to tipping over, further reducing the efficiency and safety of power grid construction. This not only affects the stability of power supply but also poses a threat to the safety of on-site personnel, failing to meet actual needs. Utility Model Content

[0004] This utility model discloses an expandable low-voltage fast networking device with a multi-load access cabinet. It aims to solve the problem that in general multi-load access cabinets, due to a lack of effective protective measures in rainy weather and muddy roads, rainwater may seep into the cabinet, leading to dampness and leakage, and in severe cases, even electric shock. Muddy ground also makes the multi-load access cabinet prone to tipping over, further reducing the efficiency and safety of power grid construction. This not only affects the stability of power supply but also poses a threat to the safety of on-site personnel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An expandable low-voltage rapid networking device with a multi-load access cabinet includes a multi-load access cabinet. Two fixed rods are fixedly connected to one side of the multi-load access cabinet. A second telescopic rod is slidably connected to the top of each fixed rod. A first telescopic rod is slidably connected to the top of the second telescopic rod. A handle is rotatably connected to the top of one of the first telescopic rods. A mounting shell is fixedly connected to the top of the other first telescopic rod. A connecting groove is provided on one side of the mounting shell, and an insertion rod is slidably connected to the other side of the mounting shell. A limiting block is fixedly connected to one end of the insertion rod. The other end is fitted with a clamping spring. One end of the handle is fixedly connected to a connector near the connecting groove. A connecting rod is slidably connected inside the first telescopic rod. A locking block is fixedly connected to the bottom end of the connecting rod. An installation cylinder is fixedly connected to one side of the multi-load access cabinet inside the fixed rod. The installation cylinder has a slot inside, which allows the locking block to be inserted into the slot without contacting the installation cylinder. A slot is provided at the top of the installation cylinder. A stabilizing nail is fixedly connected to the bottom of the installation cylinder. A stop block is slidably connected to the top of the installation cylinder. A limiting spring is provided on one side of the stop block.

[0007] In a preferred embodiment, the width and length of the slot are greater than the width and length of the card block, and the card block is rotated 90 degrees to insert into the top of the mounting cylinder from the slot, so that the mounting cylinder is connected to the connecting rod.

[0008] A rotating frame is rotatably connected to one side of the multi-load access cabinet near the bottom. Wheels are rotatably connected to both ends of the rotating frame, and buffer springs are provided on both sides of the top of the rotating frame.

[0009] The other side of the multi-load access cabinet is equipped with multiple input connectors.

[0010] Multiple relays are installed on one side of the multi-load access cabinet, above the input connector.

[0011] Multiple plug-in boards are provided on the other side of the multi-load access cabinet.

[0012] On the other side of the multi-load access cabinet, above the plug-in board, are multiple output connectors.

[0013] As can be seen from the above, the expandable low-voltage fast networking device multi-load access cabinet provided by this utility model has the following technical effects.

[0014] Firstly, to prevent the multi-load access cabinet from tipping over, pulling the plug rod compresses the clamping spring, separating the limiting block from the connector. Turning the handle causes the connector to slide out of the connecting slot, and the handle causes the connecting rod and the clamping block to rotate 90 degrees. Pressing the handle causes the connecting rod and the clamping block to slide downwards, allowing the clamping block to insert into the mounting cylinder from the slot, squeezing the abutment block and the limiting spring. After the clamping block enters the mounting cylinder, the elasticity of the limiting spring causes the abutment block and the clamping block to rotate, fixing the clamping block inside the mounting cylinder. Continuing to press the handle causes the mounting cylinder and the stabilizing pin to slide downwards, allowing the stabilizing pin to insert into the soil of the road surface, keeping the multi-load access cabinet stable and preventing it from tipping over under complex road conditions.

[0015] Secondly, during the movement of the multi-load access cabinet, due to complex road conditions, there may be potholes. The multi-load access cabinet will sway from side to side during movement. To prevent vibration from damaging the multi-load access cabinet, the multi-load access cabinet and the rotating frame rotate relative to each other when swaying from side to side. By compressing the buffer springs on both sides, the vibration of the multi-load access cabinet on potholes is reduced. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0025] The expandable low-voltage fast networking device multi-load access cabinet disclosed in this utility model is mainly used in general multi-load access cabinets. In rainy weather and muddy roads, due to the lack of effective protective measures in the design, rainwater may seep into the cabinet, causing the equipment to become damp and leak electricity. In severe cases, it may even cause electric shock accidents. Muddy ground makes the multi-load access cabinet easy to tip over, further reducing the efficiency and safety of power grid construction. This not only affects the stability of power supply, but also poses a threat to the safety of on-site personnel.

[0026] Reference Figure 1 — Figure 5An expandable low-voltage rapid networking device with multiple load access cabinet includes a multiple load access cabinet 1. Two fixed rods 7 are fixedly connected to one side of the multiple load access cabinet 1. A second telescopic rod 6 is slidably connected to the top of the fixed rods 7. A first telescopic rod 5 is slidably connected to the top of the second telescopic rod 6. A handle 4 is rotatably connected to the top of one of the first telescopic rods 5. A mounting shell 12 is fixedly connected to the top of the other first telescopic rod 5. A connecting groove 22 is provided on one side of the mounting shell 12. A plug rod 19 is slidably connected to the other side of the mounting shell 12. A limiting block 21 is fixedly connected to one end of the plug rod 19, and a locking device is sleeved on the other end of the plug rod 19. A spring 20 is attached to a connector 18 fixedly connected to one end of the handle 4 near the connecting groove 22. A connecting rod 11 is slidably connected inside a first telescopic rod 5. A locking block 10 is fixedly connected to the bottom end of the connecting rod 11. An installation cylinder 13 is fixedly connected to one side of the multi-load access cabinet 1 inside the fixing rod 7. The installation cylinder 13 has a slot inside, which allows the locking block 10 to be inserted into the slot without contacting the installation cylinder 13. A slot 14 is provided at the top of the installation cylinder 13. A stabilizing nail 17 is fixedly connected to the bottom of the installation cylinder 13. A stop block 23 is slidably connected to the top of the installation cylinder 13. A limiting spring 24 is provided on one side of the stop block 23.

[0027] In this embodiment, a power grid needs to be set up at the site of a power outage. The multi-load access cabinet 1 is the third level of the power grid and needs to be moved the furthest distance. Pulling handle 4 extends the second telescopic rod 6 and the first telescopic rod 5, facilitating the movement of the multi-load access cabinet 1 to the designated location. Upon arrival, the rescue site presents complex conditions, including muddy roads, especially in rainy weather where damp surfaces can easily cause leakage in the multi-load access cabinet 1. To prevent the multi-load access cabinet 1 from tipping over during the power grid setup, pulling the insertion rod 19 compresses the clamping spring 20, separating the limiting block 21 from the connector 18. Rotating handle 4 moves the connector 18 from the connection... The slot 22 slides out, and the handle 4 drives the connecting rod 11 and the locking block 10 to rotate 90 degrees. Pressing the handle 4 causes the connecting rod 11 and the locking block 10 to slide downward, so that the locking block 10 is inserted into the interior of the mounting cylinder 13 from the slot 14, squeezing the abutment block 23 and the limiting spring 24. After the locking block 10 enters the interior of the mounting cylinder 13, the elastic force of the limiting spring 24 causes the abutment block 23 and the locking block 10 to rotate, so that the locking block 10 is fixed inside the mounting cylinder 13. Continue to press the handle 4, causing the mounting cylinder 13 and the stabilizing nail 17 to slide downward, so that the stabilizing nail 17 is inserted into the soil of the road surface, so that the multi-load access cabinet 1 remains stable, which has the effect of preventing the multi-load access cabinet 1 from tipping over under complex road conditions.

[0028] Reference Figure 1 , Figure 3 and Figure 4In a preferred embodiment, the width and length of the slot 14 are greater than the width and length of the locking block 10. The locking block 10 is rotated 90 degrees and inserted from the slot 14 into the top of the mounting cylinder 13, so that the mounting cylinder 13 is connected to the connecting rod 11.

[0029] A rotating frame 8 is rotatably connected to one side of the multi-load access cabinet 1 near the bottom. Wheels 15 are rotatably connected to both ends of the rotating frame 8, and buffer springs 16 are respectively provided on the top two sides of the rotating frame 8.

[0030] Multiple input connectors 2 are provided on the other side of the multi-load access cabinet 1.

[0031] Multiple relays 3 are installed on one side of the multi-load access cabinet 1, above the input connector 2.

[0032] Multiple plug-in boards 9 are installed on the other side of the multi-load access cabinet 1.

[0033] On the other side of the multi-load access cabinet 1, above the plug-in plate 9, there are multiple output connectors.

[0034] In this embodiment, during the movement of the multi-load access cabinet 1, due to complex road conditions, there may be potholes on the road surface. When the multi-load access cabinet 1 is moved, it will sway left and right. To prevent the multi-load access cabinet 1 from being damaged by vibration, the multi-load access cabinet 1 and the rotating frame 8 rotate relative to each other when swaying left and right. By squeezing the buffer springs 16 on both sides, the vibration of the multi-load access cabinet 1 on the pothole road surface is reduced. The relay 3 is used to control the on and off of the circuit, the input connector 2 is used for input circuit, the plug board 9 is used to connect electrical appliances, and the output connector is used to connect the output circuit.

[0035] Working Principle: During use, a power grid needs to be established at the site of a power outage. The multi-load access cabinet 1 is the third level of the power grid and needs to be moved the longest distance. Pulling handle 4 extends the second telescopic rod 6 and the first telescopic rod 5, facilitating the movement of the multi-load access cabinet 1 to the designated location. Upon arrival, the rescue site may present complex conditions, including muddy roads, especially in rainy weather, where damp surfaces can easily cause leakage in the multi-load access cabinet 1. To prevent the multi-load access cabinet 1 from tipping over during the power grid setup, pulling the insertion rod 19 compresses the clamping spring 20, separating the limiting block 21 from the connector 18. Rotating handle 4 causes the connector 18 to slide out of the connecting slot 22. Handle 4 rotates the connecting rod 11 and the locking block 10 ninety degrees. Pressing handle 4 causes the connecting rod 11 and the locking block 10 to slide downwards, allowing the locking block 10 to insert from the slot 14 into the mounting cylinder 13, compressing the abutment block 23 and the limiting spring 24. After entering the interior of the mounting cylinder 13, the elastic force of the limiting spring 24 causes the stop block 23 and the locking block 10 to rotate, fixing the locking block 10 inside the mounting cylinder 13. Continuing to press the handle 4 causes the mounting cylinder 13 and the stabilizing pin 17 to slide downwards, allowing the stabilizing pin 17 to insert into the soil of the road surface, thus stabilizing the multi-load access cabinet 1 and preventing it from tipping over in complex road conditions. During the movement of the multi-load access cabinet 1, due to complex road conditions, potholes may appear, causing the multi-load access cabinet 1 to sway left and right. To prevent damage to the multi-load access cabinet 1 from vibration, the multi-load access cabinet 1 and the rotating frame 8 rotate relative to each other when swaying left and right, compressing the buffer springs 16 on both sides, thus reducing the vibration of the multi-load access cabinet 1 on pothole surfaces. The relay 3 is used to control the on / off state of the circuit, the input connector 2 is used for the input circuit, the plug-in board 9 is used to connect electrical appliances, and the output connector is used to connect the output circuit.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
