[0001] This utility model relates to the field of low-voltage switchgear, specifically a complete set of low-voltage switchgear. Background Technology
[0002] A complete set of low-voltage switchgear is a highly integrated, factory-manufactured power control center customized for low-voltage power systems. It safely, reliably, and flexibly distributes and protects the low-voltage power output from the transformer to end-use equipment such as motors, lighting, air conditioners, and sockets. It is an indispensable basic hardware facility in modern power systems, and its performance and quality are directly related to the safe, stable, and efficient operation of the entire power distribution system. Its core value lies in providing safe, standardized, easy-to-manage, and scalable power distribution and protection solutions.
[0003] In the operation of existing low-voltage switchgear, control switches are installed inside to control the equipment. However, due to the large number of control switches, there are many internal wires, resulting in messy wiring and causing inconvenience during routine maintenance and inspection. Therefore, the inventor urgently needs to design a device that can neatly manage the cables to improve the cleanliness of the cabinet. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a complete set of low-voltage switchgear to solve the technical problem of mess inside the cabinet.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a complete set of low-voltage switchgear, including a cabinet, an installation plate is provided inside the cabinet, a plurality of through holes are provided on the surface of the installation plate, a locking mechanism is fixedly provided on one side of each through hole of the installation plate, the locking mechanism includes an installation block, two moving blocks are provided in the groove of the installation block, a plurality of wire-locking grooves are provided on one side of the moving block, and an insect repellent box is provided on the inner bottom plate of the cabinet.
[0006] By adopting the above technical solution, a systematic cable management framework is constructed by setting up mounting plates, through holes, locking mechanisms, and insect repellent boxes inside the cabinet. This effectively solves the maintenance difficulties caused by messy wires in traditional equipment. The design of the mounting blocks and moving blocks of the locking mechanism, combined with the layout of the cable trays, ensures that the wires can be directly guided to fixed positions after passing through the through holes, achieving uniformity of the wire path and reducing the risk of messy cable routing. This significantly improves the tidiness inside the cabinet, allowing maintenance personnel to quickly identify and locate cables during daily inspections without the need for additional cleaning of messy wires, thus reducing the probability of operational errors.
[0007] Furthermore, a limiting rod is fixedly installed above the movable block, and one end of the limiting rod is provided with a slot. The two limiting rods are fixed in position using rubber rings.
[0008] By adopting the above technical solution, the rubber ring is fixed in position, which enhances the stability of the clamping mechanism. The application of the rubber ring provides flexible clamping force, which can not only adapt to wires of different diameters, but also effectively absorb the vibration energy during equipment operation, preventing the wires from loosening or slipping. This significantly improves the reliability in long-term operation, and maintenance personnel do not need to frequently adjust the fixing device, reducing the workload of maintenance.
[0009] Furthermore, a rotating block is coaxially rotatable above the mounting block, and the surface of the rotating block is provided with two sliding grooves, which limit the position of the limiting rod.
[0010] By adopting the above technical solution, the rotating block and the sliding mechanism rotate coaxially with the mounting block, making the position control of the limit rod more precise. The sliding groove of the rotating block guides the movement of the limit rod, ensuring a smooth transition to the locked state during rotation operation, avoiding jamming problems during manual operation. This significantly improves the user-friendliness of the locking mechanism. When arranging cables, maintenance personnel can quickly rotate the rotating block to open and close the moving block, achieving the release or fixation of the wire in seconds, reducing downtime.
[0011] Furthermore, the insect repellent box has an interior drawer for storing insect repellent packets.

[0013] Furthermore, a cover plate is provided on the top of the insect repellent box, and the surface of the cover plate is provided with several through holes.
[0014] By adopting the above technical solution, the through holes are evenly distributed, allowing air circulation without affecting the insect-repellent effect. This solves the problem of excessive evaporation or blockage in traditional open-hole designs, which significantly optimizes the insect-repellent efficiency. The through holes in the cover plate can adjust the evaporation rate of the insect repellent, ensuring its even distribution in the cabinet and improving the protective coverage.
[0015] Furthermore, a support frame is provided below the cabinet, which is used to change the height of the cabinet.
[0016] By adopting the above technical solution and adding a support structure, the height is adjustable, which solves the equipment stability problem caused by uneven or damp ground. The support allows the operator to adjust the cabinet height according to the site conditions, ensuring a safe distance between the equipment and the ground. This significantly enhances the moisture and dust prevention capabilities, effectively isolates moisture at the bottom, and reduces the risk of electrical short circuits.
[0017] Furthermore, a first door is hinged to one side of the cabinet, and the surface of the first door is provided with several displays and control buttons, and the surface of the first door is provided with a first handle. A second door is hinged to the other side of the cabinet, and the surface of the second door is provided with a second handle.
[0018] By adopting the above technical solution, the dual-door design separates the operation and maintenance functions, solving the problem of misoperation or maintenance conflicts. The first door integrates a display and control buttons, which facilitates real-time monitoring of parameters and debugging. The second door is dedicated to the maintenance passage, avoiding interference from the front door. This significantly improves operational safety, and maintenance personnel can directly access internal components through the second door, reducing the risk of accidentally touching control buttons.
[0019] Furthermore, the cabinet is equipped with a mounting rack inside, and a number of control switches are provided on one side of the mounting rack.
[0020] By adopting the above technical solution, a core control unit for the equipment was constructed. Multiple control switches were fixed in the mounting bracket, and electrical components were centrally managed. This solved the problem of low control efficiency caused by the dispersed switches in traditional equipment. This significantly improved the response speed, and the operator could quickly execute commands through the centralized switch, reducing the time for troubleshooting.
[0021] In summary, the present invention has the following main advantages:
[0022] 1. This utility model achieves rapid positioning and fixing of wires through the linkage design of the rotating block and the moving block of the locking mechanism. During operation, simply rotating the rotating block will simultaneously drive the two moving blocks to close, accurately pressing the wire into the middle of the wire locking groove. The wire management is completed in a single step, reducing the cumbersome process of traditional screw fixing or cable tie binding. At the same time, the locking groove of the limiting rod, together with the rubber ring, forms a flexible constraint, effectively absorbing the high-frequency vibration during equipment operation, avoiding long-term stress on the wires that may cause insulation wear or loosening of connection points, and significantly reducing the risk of circuit breakage.
[0023] 2. This utility model provides controllable insect protection through the drawer design of the insect repellent box combined with the through-hole design of the cover plate.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0032] In this embodiment:
[0033] A complete set of low-voltage switchgear, such as Figure 1-6As shown, the device includes a cabinet 1, inside which is a mounting plate 5. The surface of the mounting plate 5 has several through holes. A locking mechanism 6 is fixedly installed on one side of each through hole. The locking mechanism 6 includes a mounting block 601, with two movable blocks 602 positioned in the groove of the mounting block 601. Several cable management slots 605 are provided on one side of each movable block 602. An insect repellent box 7 is installed on the inner bottom plate of the cabinet 1. The mounting plate, through holes, locking mechanism, and insect repellent box inside the cabinet create a systematic cable management framework, effectively solving the maintenance difficulties caused by messy wires in traditional equipment. The design of the mounting blocks and movable blocks in the locking mechanism, combined with the layout of the cable management slots, ensures efficient cable management. After passing through the through-holes, the cables can be directly guided to fixed positions, achieving a unified cable path and reducing the risk of tangled cabling. This significantly improves the tidiness inside the cabinet, allowing maintenance personnel to quickly identify and locate cables during routine inspections without the need for additional cable management, thus reducing the probability of operational errors. Meanwhile, the insect repellent box integrated into the cabinet base actively prevents flying insects or pests from damaging internal cables, extending equipment lifespan. This structure also enhances the modularity of the equipment, facilitating standardized operations during production or on-site assembly and reducing manufacturing costs. Furthermore, the overall design fully considers ventilation and heat dissipation, avoiding overheating issues in areas with dense wiring and improving equipment safety.
[0034] See Figure 5 , Figure 6 A limiting rod 603 is fixedly installed above the moving block 602. One end of the limiting rod 603 is provided with a slot 604. The two limiting rods 603 are fixed in position using rubber rings. The rubber rings enhance the stability of the locking mechanism. The application of rubber rings provides flexible clamping force, which can adapt to wires of different diameters and effectively absorb the vibration energy of the equipment during operation, preventing the wires from loosening or slipping. This significantly improves the reliability in long-term operation. Maintenance personnel do not need to frequently adjust the fixing device, reducing maintenance workload. At the same time, the simplicity of the slot design allows for one-handed operation of the limiting rod locking action, simplifying the cable management process, avoiding the use of traditional screw fixing tools, and improving operational efficiency. In addition, this design automatically buffers stress when the wire is compressed, reducing potential damage to the insulation layer and ensuring electrical safety. Meanwhile, the replaceable nature of the rubber rings facilitates timely replacement when they age, extending the service life of equipment components and reducing overall maintenance costs.
[0035] See Figure 5 , Figure 6A rotating block 606 is coaxially rotatable above the mounting block 601. The surface of the rotating block 606 has two sliding grooves 607, which limit the position of the limiting rod 603. The rotating block and sliding groove mechanism rotate coaxially with the mounting block, making the position control of the limiting rod more precise. The sliding grooves of the rotating block guide the movement of the limiting rod, ensuring a smooth transition to the locked state during rotation, avoiding jamming problems caused by manual operation. This significantly improves the user-friendliness of the locking mechanism. Maintenance personnel can quickly rotate the rotating block to open and close the moving block when managing cables, achieving second-level release or fixation of the wires, reducing downtime. Simultaneously, the physical limitation of the sliding grooves provides visual feedback for wire fixation, allowing operators to intuitively judge the locking status and prevent loose clamping or excessive compression of the wires. This design also enhances the durability of the equipment; the sliding groove structure reduces wear and extends the life of mechanical parts. Furthermore, the low torque characteristics of the rotational action reduce the physical burden during operation, making it suitable for confined spaces or high-density cabinet scenarios, improving overall work efficiency and safety.
[0036] See Figure 1 , Figure 2 The insect repellent box 7 has an internal drawer 701 for storing insect repellent packets. This solves the problem of traditional insect repellent devices being difficult to replace and maintain. The drawer is specifically designed for storing insect repellent packets and can be easily pulled out to replace or refill the repellent material without disassembling the cabinet or interrupting equipment operation. This significantly improves maintenance convenience, allowing on-site personnel to regularly check and replace the insect repellent packets to ensure the continuous effectiveness of insect repellency and reduce the risk of short circuits caused by flying insect intrusion. At the same time, the drawer's structure physically isolates the insect repellent packets from electrical components, preventing chemicals from directly contacting wires and reducing the possibility of corrosion or insulation damage. In addition, this design facilitates the management of insect repellent resources, such as selecting camphor or environmentally friendly insect repellents according to different environments. Furthermore, the independent space of the drawer reduces the spread of odors within the cabinet, maintains the cleanliness of the air inside the equipment, and improves the quality of the operating environment.
[0037] See Figure 1 , Figure 2 The insect repellent box 7 is equipped with a cover plate 702 on its top. The surface of the cover plate 702 has several through holes that are evenly distributed, allowing air circulation without affecting the insect repellent effect. This solves the problem of excessive evaporation or clogging in traditional open-hole designs, which significantly optimizes the insect repellent efficiency. The through holes in the cover plate can adjust the evaporation rate of the insect repellent, ensuring that it is evenly distributed in the cabinet and improving the protective coverage. At the same time, the through-hole structure can also prevent external dust or foreign objects from entering the insect repellent box, keeping the inside clean and reducing the frequency of maintenance. In addition, the protective design of the cover plate extends the service life of the insect repellent pack, preventing moisture or physical damage. The through holes also serve as a heat dissipation aid, improving the thermal management at the bottom of the cabinet, preventing equipment failure due to temperature accumulation, and improving overall reliability.
[0038] See Figure 1 , Figure 2 , Figure 3 , Figure 4 A bracket 8 is installed below the cabinet 1. The bracket 8 is used to change the height of the cabinet 1. The addition of the bracket structure provides height adjustment function, which solves the equipment stability problem caused by uneven ground or moisture. The bracket allows the operator to adjust the height of the cabinet according to the site conditions, ensuring a safe distance between the equipment and the ground. This significantly enhances the moisture and dust prevention capabilities, effectively isolates moisture at the bottom, and reduces the risk of electrical short circuits. At the same time, the height adjustment capability facilitates quick positioning of the equipment during installation or relocation, improving site adaptability. In addition, the bracket design also optimizes the center of gravity distribution of the cabinet, reducing the impact of vibration during operation. It simplifies the foundation preparation work, eliminates the need for additional ground piles, and reduces deployment costs and maintenance complexity.
[0039] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The cabinet 1 has a first door 4 hinged to one side, with several displays 401 and control buttons 402 on its surface, and a first handle 403 on its surface. The cabinet 1 also has a second door 9 hinged to the other side, with a second handle 901 on its surface. This dual-door design separates operation and maintenance functions, solving the problem of misoperation or maintenance conflicts. The first door integrates displays and control buttons, facilitating real-time parameter monitoring and debugging. The second door is dedicated to the maintenance passage, avoiding interference from the front door, which significantly improves operational safety. Maintenance personnel can directly access internal components through the second door, reducing the risk of accidental button presses. At the same time, the dual-door structure optimizes space utilization, and the integration of displays and control buttons provides an intuitive human-machine interface, shortening the training cycle. In addition, the hinged installation ensures smooth door opening and closing, and the ergonomic handle design enhances operational comfort and efficiency.
[0040] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The cabinet 1 contains a mounting rack 2, and several control switches 3 are mounted on one side of the mounting rack 2, forming the core control unit of the equipment. The mounting rack fixes multiple control switches, centralizing the management of electrical components and solving the problem of low control efficiency caused by scattered switches in traditional equipment. This significantly improves the response speed, and operators can quickly execute commands through the centralized switches, reducing troubleshooting time. At the same time, the mounting rack structure provides stable support for the switches, reducing vibration interference. In addition, this design facilitates expansion and upgrades, and the reasonable layout of the control switches optimizes the internal space, ensures ventilation and heat dissipation, and improves overall performance.
[0041] The implementation principle of this embodiment is as follows: When organizing cables, the second door 9 is opened, the wire of the control switch 3 is passed through the through hole of the mounting plate 5, and then through the internal gap of the locking mechanism 6. The rotating block 606 is rotated, the position of the limit rod 603 is changed, and the two moving blocks 602 are closed. The wire is placed in the middle of the wire clamping groove 605 for fixation. A rubber ring is used to clamp the limit rod 603 in the groove 604 to fix the position of the limit rod 603 and prevent the wire from loosening. An insect-proof bag is placed inside the drawer 701. The air in the insect-proof bag is released through the through hole of the cover plate 702 to prevent the internal cables from being bitten by flying insects. The bracket 8 increases the height of the cabinet 1 and plays a role in moisture prevention.
