Detailed Implementation Methods

[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0046] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0047] In this invention, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this invention and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0048] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0049] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0050] Please see Figure 1 and Figure 2The first embodiment of this utility model provides a power supply box 100, including a box body 1, and a power strip 2, a power supply device 3, and a power supply wire 4 disposed on the box body 1. The power strip 2 is provided with multiple output circuits 5, each output circuit 5 including a safety socket 51, a disconnect switch 52, and a leakage current protector 53 connected in sequence. The power supply wire 4 is electrically connected to the output circuit 5, the input end of the power supply device 3 is electrically connected to the power supply wire 4, and the output end is electrically connected to at least one output circuit 5.

[0051] Optionally, the disconnecting switch 52 can be a double-pole disconnector, a three-pole disconnector, or other types of switch, as long as it can control the opening and closing of the circuit and quickly cut off the power supply in an emergency.

[0052] As a feasible implementation method, the disconnect switch 52 is specifically a double-pole knife switch. The socket panel 2 integrates three output circuits 5. Each output circuit 5 consists of a safety socket 51, a double-pole knife switch, and a leakage current protector 53 connected in series. The three output circuits 5 are connected in parallel with each other and connected in series with the take-off wire 4.

[0053] Understandably, by setting up a separate socket, isolating switch 52, and leakage current protection device 53 for each output circuit 5, the independent switching and leakage current protection of the output circuit 5 can be achieved, which complies with the power industry's "one machine, one switch, one protection" operating standard, so as to significantly reduce the risk of electric shock and short circuit.

[0054] Specifically, the output circuits 5 are arranged in parallel with staggered positions.

[0055] It should be noted that the power supply device 3 is located on the left side of the socket panel 2, and multiple safety sockets 51 are arranged parallel to each other on the right side of the socket panel 2. The multiple safety sockets 51 are arranged at intervals along a straight line. Above each safety socket 51, there is a disconnect switch 52 and a residual current device 53 arranged in sequence. The safety sockets 51, disconnect switches 52 and residual current devices 53 are located on a straight line.

[0056] Understandably, the design of the multi-output circuit 5 can simultaneously power different devices, meet the multi-load requirements of the maintenance site, and optimize load management.

[0057] It should be understood that the staggered parallel layout of the multi-output circuits reduces electromagnetic interference between circuits and improves heat dissipation efficiency, avoiding overheating problems caused by dense arrangement; secondly, the staggered arrangement makes it easier for maintenance personnel to quickly identify and operate specific circuits, improving work efficiency.

[0058] Furthermore, part of the output circuit 5 is directly connected to the power take-up wire 4, and part is connected to the power take-up wire 4 through the power supply device 3.

[0059] It should be noted that when the power cord 4 is not connected to an external power source, the output circuit 5, which is electrically connected to the power supply device 3, can supply power to the power supply box 100 and / or the device plugged into the safety plug of the output circuit 5; when the power cord 4 is connected to an external power source, each output circuit 5 on the power strip panel 2 can supply power to the power supply box 100 and / or the device plugged into the corresponding safety socket 51.

[0060] In one implementation, the power supply unit 3 is an uninterruptible power supply (UPS). When the mains input is normal, the UPS regulates the mains voltage and supplies it to the load. At this time, the UPS acts as an AC voltage regulator and also charges its internal battery. When the mains power is interrupted, the UPS immediately switches from the battery's DC power to the load via an inverter, continuing to supply 220V AC power to maintain the load's normal operation and protecting the load's hardware and software from damage. UPS devices typically provide protection against both overvoltage and undervoltage.

[0061] Understandably, this design provides the power supply box 100 with dual power supply, both internal and external, enabling the power supply box 100 to seamlessly switch between mains power and internal power. Depending on the actual conditions at the maintenance site, the appropriate power supply line can be switched to supply power to the power supply box 100, ensuring that the power supply box 100 can operate normally even in the event of a power outage or absence of mains power, thus meeting the different application scenarios of power grid maintenance.

[0062] As an optional implementation, the power strip panel 2 is provided with a main switch 54 to control the start and stop of all output circuits 5. When the main switch 54 is closed, even if the isolating switch 52 and the leakage current protector 53 in the output circuit 5 are both closed, power cannot be supplied normally. When the main switch 54 is open, the output circuit 5 can work normally.

[0063] Furthermore, please combine Figure 2 and Figure 5 The housing 1 is also equipped with a cable reel 6, on which the wire 4 is wound.

[0064] Specifically, the box body 1 has a storage chamber 13 inside, and a rotatable opening and closing cover 11 is provided on the side of the box body 1. One side of the opening and closing cover 11 is fixedly installed on the box body 1, and the other side is detachably connected to the box body 1. The opening and closing cover 11 can close or expose the storage chamber 13, and the cable reel 6 is stored in the storage chamber 13.

[0065] In a specific embodiment, the length of the take-up wire 4 is 20 meters. The length of the take-up wire 4 can be adjusted according to actual needs. The reel 6 is fixed below the plug panel 2. One end of the take-up wire 4 is connected to the output circuit 5, and the other end is wound on the reel 6. The reel 6 can rotate around its central axis. The take-up wire 4 can be stored or released through the rotation of the reel 6.

[0066] It should be noted that when not in operation, the take-up cable 4 is stored and wound on the reel 6. When an external power supply is required, the take-up cable 4 is pulled out from the reel 6 to a corresponding length to connect to the external power supply. Specifically, the reel 6 is equipped with a locking structure. After the take-up cable 4 is pulled out to a preset length, the reel 6 stops rotating under the action of the locking structure, so that the pulled-out take-up cable 4 is fixed at the current length. Power maintenance personnel can pull out the take-up cable 4 to a corresponding length according to the actual working scenario, that is, the distance of the power supply on site, to adapt to power interfaces of different distances and meet different maintenance site requirements.

[0067] Understandably, this embodiment avoids cable tangling by orderly winding the take-up cable 4 onto the reel 6, thereby enabling quick take-up and take-up of the take-up cable 4, which is convenient for carrying in the field; after the take-up cable 4 is wound and stored, the exposed cable is reduced, reducing dragging wear and the risk of accidental tripping.

[0068] Further, please refer to Figure 3 , Figure 4 and Figure 10 The end of the power cord 4 away from the output circuit 5 is provided with an adapter 41, and the housing 1 houses multiple adapters 42 that mate with the adapter 41.

[0069] It should be noted that the box body 1 is provided with a cover 7, which is rotatably connected to the box body 1. The cover 7 is provided with a first storage groove 71 on the side near the plug panel 2. The first storage groove 71 contains an adapter 42, which is detachably installed in the first storage groove 71.

[0070] Specifically, the first storage slot 71 contains various types of adapters 42, such as triangular connectors, U-shaped plug connectors, and / or circuit breaker plug connectors.

[0071] Understandably, the adapter 42 and the power supply cable 4 are placed in the first storage slot 71 and the storage chamber 13 respectively, which can avoid the corresponding cables from getting mixed up or lost. By using a single power supply cable 4 with adapters 42 of various connector types, that is, by connecting the corresponding adapter 42 to the adapter interface 41, the power supply box 100 can be connected to distribution boxes or generators of different specifications, which increases the convenience of maintenance work and expands the application scenarios of the power supply box 100.

[0072] Furthermore, the adapter 41 is provided with a first snap-fit ​​structure 411, the adapter 42 is fitted with a sleeve 422, the sleeve 422 is provided with a second snap-fit ​​structure 421 that cooperates with the first snap-fit ​​structure 411, the sleeve 422 is rotatably connected to the adapter 42, and the sleeve 422 rotates relative to the adapter 42 to make the first snap-fit ​​structure 411 and the second snap-fit ​​structure 421 misaligned.

[0073] It should be noted that the first snap-fit ​​structure 411 is a protrusion spaced apart on the outer periphery of the adapter 41. The first snap-fit ​​structure 411 has an inclined surface at one end near the adapter 42 and a vertical surface at the other end. The second snap-fit ​​structure 421 is a protrusion spaced apart on the inner periphery of the sleeve 422. When the sleeve 422 is engaged with the adapter 41, the second snap-fit ​​structure 421 abuts against the outer periphery of the adapter 41.

[0074] Understandably, the sleeve 422 has a certain degree of elasticity. When the adapter 42 and the adapter interface 41 are locked, the second snap-fit ​​structure 421 moves along the inclined surface of the first snap-fit ​​structure 411 to the rear end of the first snap-fit ​​structure 411, thereby engaging the first snap-fit ​​structure 411 and the second snap-fit ​​structure 421, so that the adapter 42 and the adapter interface 41 are mechanically locked, preventing the adapter 42 and the adapter interface 41 from becoming loose due to dragging or vibration.

[0075] Specifically, there is a height difference between the first snap-fit ​​structure 411 and the second snap-fit ​​structure 421. Therefore, when the first snap-fit ​​structure 411 and the second snap-fit ​​structure 421 are engaged, there will be obvious snap-fit ​​feedback, so that the user can know in time that the adapter 42 and the adapter interface 41 have been locked.

[0076] It should be further explained that the sleeve 422 is rotatably connected to the adapter 42. The sleeve 422 can rotate ±10° relative to the adapter 42. The rotation angle can be adapted according to actual needs. When the first locking structure 411 and the second locking structure 421 are engaged, the sleeve 422 is rotated until the second locking structure 421 is misaligned with the first locking structure 411, so that the first locking structure 411 and the second locking structure 421 are released from the locking state, thereby allowing the adapter 42 and the adapter interface 41 to be quickly disassembled.

[0077] Furthermore, please refer to the following: Figure 1 The safety socket 51 includes a two-hole socket and a three-hole socket, which can operate in different time slots.

[0078] Optionally, the safety socket 51 is a five-hole socket, which integrates a two-hole socket and a three-hole socket, allowing for the connection of devices with two-prong plugs or three-prong plugs, thus providing greater adaptability.

[0079] In a specific embodiment, the two-hole socket and the three-hole socket on the same safety socket 51 cannot be connected to external devices at the same time. That is, one safety socket 51 can only be connected to one device at a time. The two-hole socket and the three-hole socket of one safety socket 51 are used in a time-sharing manner, which can avoid the safety socket 51 from being overloaded due to multiple external devices being connected at the same time.

[0080] Furthermore, the safety socket 51 is provided with an openable cover 511 on the outside.

[0081] It should be noted that one side of the cover plate 511 is rotatably connected to the safety socket 51, so that the cover plate 511 can be opened or closed relative to the safety socket 51. When the safety socket 51 is not in operation, the cover plate 511 is closed on the safety socket 51, reducing the risk of accidental contact with live sockets through physical shielding. The cover plate 511 can also prevent rainwater and dust from entering the safety socket 51, extending the service life of the safety socket 51.

[0082] Please continue reading. Figure 1 The power strip panel 2 is also equipped with a display module 21, which is used to display power consumption, voltage and / or power.

[0083] It should be noted that the display module 21 includes a display screen and is electrically connected to the power supply line 4. When the power supply line 4 is connected to an external power source, the display module 21 is powered and starts to work, detecting the current voltage, power consumption and / or power of the power supply box 100, and displaying it on the display screen of the display module 21 in real time.

[0084] Understandably, the real-time display module 21 shows the power consumption parameters, allowing users to monitor the power consumption and operating status of the power supply box 100, optimize power distribution in a timely manner, and prevent overload or voltage abnormalities. Simultaneously, the real-time display of power consumption parameters facilitates user analysis of equipment energy consumption and adjustment of load management. This design enhances the intelligence of the power supply box 100, provides users with more information, facilitates monitoring and management of the charging process, and improves the safety and reliability of its use.

[0085] Furthermore, the power strip panel 2 is also equipped with a power switch 22 and a power indicator light 23. The power switch 22 is used to control the connection between the power supply device 3 and the power cord 4, and the power indicator light 23 is used to indicate the working status of the power supply device 3.

[0086] It should be noted that the power indicator light 23 includes a fault light and a working light. When the power supply device 3 is working normally, the working light is on; when the power supply device 3 is faulty or in a non-working state, the fault light is on. Specifically, the working light is green and the working light is red. The different colors of the lights allow the user to quickly understand the current operating status of the power supply device 3.

[0087] As a feasible implementation method, the power switch 22 is used to control the connection between the power supply device 3 and the power take-up wire 4. When the power take-up wire 4 is connected to an external power source, the power switch 22 needs to be turned on to electrically connect the power supply device 3 and the power take-up wire 4. At this time, the power take-up wire 4, the power supply device 3, and the output circuit 5 connected to the power supply device 3 are electrically connected in sequence, that is, the corresponding output circuit 5 is in a conducting state. At the same time, the power take-up wire 4 is also charging the power supply device 3 so that the power supply device 3 can still supply power to the output circuit 5 when it is not connected to the mains power, thus meeting the maintenance needs of the site without mains power.

[0088] Understandably, the power indicator light 23 and the display module 21 form a visual human-computer interaction interface, allowing users to understand the working status of the power supply box 100 in real time and perform corresponding operations on the power supply box 100 immediately, thereby improving the user experience and reducing misoperation.

[0089] Further, please refer to Figure 10 and Figure 11 The cover 7 is also provided with a second storage slot 72 on the side near the box 1. The second storage slot 72 contains a light 721, which is detachably installed in the second storage slot 72.

[0090] In the power supply box provided by this utility model embodiment, a lighting lamp 721 is stored inside the second storage slot 72. The lighting lamp 721 can be used to provide lighting in poor light conditions or various emergency situations, thereby improving the practicality and versatility of the power supply box.

[0091] Specifically, the end of the lighting lamp 721 is provided with a first light-emitting position 7211, and the outer circumferential surface of the lighting lamp 721 is provided with a second light-emitting position 7212. When the lighting lamp 721 is placed in the second storage slot 72, the second light-emitting position 7212 is exposed.

[0092] It should be noted that the first light-emitting position 7211 is located at the end of the lighting lamp 721 to enable power maintenance personnel to achieve handheld precision lighting, which is suitable for delicate power maintenance operations.

[0093] Furthermore, the second light-emitting position 7212 is set on the circumferential outer surface of the lighting lamp 721. When the lighting lamp 721 is stored in the second storage slot 72, the second light-emitting position 7212 is exposed to provide auxiliary lighting for the environment of the box 1 for power maintenance personnel, freeing up the hands of power maintenance personnel and thus improving the efficiency of power maintenance work.

[0094] In some embodiments, the cover 7 is further provided with a third storage slot 73 on the side near the box body, and a warning sign is stored inside the third storage slot 73. The warning sign is detachably disposed in the third storage slot 73. And / or, the cover 7 is further provided with a fourth storage slot 74 on the side near the box body, and an anemometer is stored inside the fourth storage slot 74. The anemometer is detachably disposed in the fourth storage slot 74.

[0095] In the power supply box 100 provided in this embodiment of the utility model, the warning sign is stored inside the third storage slot 73 and the anemometer is stored inside the fourth storage slot 74, which enables the power supply box 100 to have a corresponding anti-violation function. The warning sign and the anemometer are stored in a centralized manner, avoiding scattered storage that would affect the efficiency of power maintenance work.

[0096] Understandably, without an anemometer at the work site at height, it is impossible to accurately determine the wind force level; and without test fences, "Stop at High Voltage Danger" signs hanging on the fences, and without supervision, serious power accidents are likely to occur.

[0097] It should be noted that warning signs can be hung outwards by power maintenance personnel during operations to clearly mark the risks in the work area, prevent unauthorized personnel from accidentally entering or misoperating, and achieve a warning effect to reduce the probability of accidents; the anemometer can be used by power maintenance personnel at any time to measure the wind force level on site when working at heights, thereby judging the construction conditions.

[0098] In some embodiments, the interior of the receiving chamber 13 is further provided with an insulating glove, a stainless steel wire channel, an insulating pad, and / or a discharge rod.

[0099] In the power supply box 100 provided in this embodiment of the utility model, the storage chamber 13 is equipped with insulating gloves, stainless steel cable trays, insulating pads and / or discharge rods to enable the power supply box 100 to have corresponding anti-violation functions. The insulating gloves and insulating pads can form dual protection for personnel and the environment, while the discharge rods and cable trays improve the safety of power maintenance operations from the aspects of energy release and line management.

[0100] Specifically, by using insulated gloves, power maintenance personnel can avoid violations such as "operators not wearing insulated gloves or using cotton gloves instead"; by using stainless steel cable trays, they can avoid violations such as "power lines being repeatedly run over by trolleys or vehicles or repeatedly stepped on by operators without protective measures"; by using insulated mats, they can avoid violations such as "high-voltage test operators not standing on insulated mats"; and by using discharge rods, they can avoid violations such as "failure to discharge and ground when replacing test leads", "failure to disconnect the test power supply", and "ungrounded metal casing of test equipment".

[0101] It should be noted that insulating gloves provide an insulating barrier, preventing direct contact between power maintenance personnel and live parts, thus preventing electric shock accidents and ensuring hand dexterity and reliable protection under complex power maintenance conditions; stainless steel cable trays are fixedly installed on the ground, with cables running through the internal channels, avoiding the risk of short circuits or open circuits caused by cable entanglement, wear, or accidental pulling, extending the service life of the power supply box by 100%; insulating mats are laid in the power maintenance work area to block the conductive circuit between the human body and the ground, reducing the risk of secondary electric shock caused by step voltage or leakage; discharge rods can meet the requirement of first discharging with resistance and then short-circuiting to ground, reducing the risk of power maintenance personnel approaching live parts.

[0102] In this embodiment, the interior of the receiving chamber 13 is equipped with an insulating glove, a stainless steel wire trough, an insulating pad, and a discharge rod. The insulating glove, discharge rod, and insulating pad are all rated at 10kV and are mainly used for testing and experimentation of high-voltage electrical equipment at the 10kV voltage level. The insulating pad has a size of 100cm × 60cm.

[0103] In this embodiment, the insulating gloves, stainless steel cable trays, insulating pads and discharge rods are stored together in the storage chamber 13, which can ensure that they can be quickly retrieved in case of emergencies and shorten the preparation time for power maintenance operations.

[0104] Further reading Figures 6 to 8 The enclosure 1 is also equipped with a bracket assembly 12. The power supply device 3 and the power strip panel 2 are both installed on the bracket assembly 12. The bracket assembly 12 separates the power supply device and the power strip panel storage chamber 13. The bracket assembly 12 separates the modules of the power supply box 100, optimizes the internal structural layout of the power supply box 100, and improves the structural stability and the flexibility and convenience of use of the power supply box 100.

[0105] In some embodiments, the support assembly 12 includes a transverse support 121, a longitudinal support 122, and a partition plate 123. The hardness of the transverse support 121 and the longitudinal support 122 is greater than that of the partition plate 123. The transverse support 121 and the partition plate 123 are respectively connected and fixed to the longitudinal support 122 at an angle. The transverse support 121 and the longitudinal support 122 are fixedly installed on the inner wall of the housing 1. The transverse support 121 is disposed on the side near the cover 7 and is used to place the power supply device 3. The partition plate 123 is located between the transverse support 121 and the bottom wall of the storage chamber 13 and is used to separate the power supply device 3 from the storage chamber 13.

[0106] In the power supply box 100 provided in this embodiment of the utility model, the horizontal support 121, the vertical support 122 and the partition plate 123 constitute the support assembly 12. The horizontal support 121 and the vertical support 122 cooperate to form the core load-bearing frame of the box 1. Its high rigidity can stably support the weight of the power supply device 3 and prevent the box 1 from deforming and affecting the service life of the power supply box 100. The partition plate 123 is located between the horizontal support 121 and the bottom wall of the storage chamber 13. Its main function is to separate the power supply device 3 from the storage chamber 13. Therefore, the partition plate 123 can be made of a material with low hardness, thereby reducing the manufacturing cost of the partition plate 123 and thus saving the assembly cost of the power supply box 100.

[0107] It should be noted that the partition 123 separates the power supply device 3 from the storage chamber 13, which on the one hand realizes the vertical layering design of the box 1, makes reasonable use of the limited internal space of the box 1, and improves the utilization rate of the internal space.

[0108] On the other hand, the spacer 123, as a physical barrier, can reduce electromagnetic interference to the power supply device 3 and prevent electrical maintenance tools such as discharge rods or cables from accidentally contacting the power supply device 3, thereby reducing the risk of short circuits or accidental contact with the power supply device 3.

[0109] Understandably, in this embodiment, the power supply device 3 is placed on the horizontal support 121, and the horizontal support 121 is positioned opposite to the side near the cover 7. Therefore, the power supply box 100 can be opened by rotating the cover between the box 1 and the cover 7, and the power supply device 3 can be operated directly without disassembling other parts, thereby improving the efficiency of power maintenance work.

[0110] Combination Figure 9 and Figure 10 In some embodiments, the side of the housing 1 away from the cover 7 is defined as the placement surface 14, and a plurality of support feet 141 are arranged in an array on the placement surface 14.

[0111] In the power supply box 100 provided in this embodiment of the utility model, multiple support feet 141 are arranged in an array on the side of the box 1 away from the cover 7. The support feet 141 can distribute the weight of the box 1 to avoid uneven local force, which may cause the power supply box 100 to tilt or shake during use, protect the circuit components inside the box 1, and improve the placement stability of the power supply box 100 on complex road surfaces.

[0112] It should be noted that since most power maintenance work is located outdoors, the ground environment is relatively harsh. By raising the bottom of the box 1, the support feet 141 can avoid direct contact with the ground, which can reduce the possibility of water seepage or dust accumulation to a certain extent, making it suitable for humid or dusty environments. On the other hand, it can prevent the bottom surface of the box 1 from being directly worn or scratched, thus extending the service life of the power box 100.

[0113] In this embodiment, there are four support feet 141, which are respectively set at the four corners of the placement surface 14. It can be understood that the number of support feet 141 can be adjusted according to actual needs. The setting of the number of support feet 141 only needs to ensure that the power box 100 can be placed stably and that the power box 100 will not be affected by the setting of support feet 141. The above description is only one embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions and improvements made within the principles of this utility model should be included within the protection scope of this utility model.

[0114] In addition, the array arrangement of the support feet 141 can also enhance the rigidity of the enclosure 1 structure, thereby ensuring the uniformity and stability of the power supply box 100, making the power supply box 100 easier to move and use between different maintenance sites, and expanding its application range.

[0115] In some embodiments, the side of the housing 1 with the opening and closing cover 11 is defined as the first outer side 15, and the side of the housing 1 away from the first outer side 15 is defined as the second outer side 16; wherein, the second outer side 16 is provided with casters 161, and the side of the placement surface 14 near the first outer side 15 is also provided with a telescopic rod 151.

[0116] The power box 100 provided in this embodiment of the utility model is equipped with casters 161 and telescopic rods 151, which can better realize the transfer of the power box 100 between construction sites and increase the passability of the power box 100 on complex road surfaces.

[0117] It should be noted that the casters 161 allow the power box 100 to maneuver more flexibly in confined spaces or on complex terrains, avoiding the need to frequently lift or drag the power box 100 and reducing the difficulty of handling; the telescopic rod 151 has an adjustable height to accommodate different user heights, providing a comfortable grip and reducing back fatigue when pushing; when the telescopic rod 151 is in the retracted state, it does not occupy additional external space, maintaining the clean appearance of the power box 100.

[0118] It is understood that in this embodiment, the cooperation between the caster wheel 161 and the telescopic rod 151 can meet the needs of emergency maintenance scenarios and is suitable for cross-regional operations of heavy equipment, thereby significantly saving labor costs.

[0119] Please see Figure 6 As a feasible implementation method, a grounding pin 17 is provided on the outer surface of the enclosure 1. Understandably, the grounding pin 17 and the metal bracket work together to form a low-impedance grounding path, and leakage is constructed through physical grounding to ensure the long-term reliability of the power supply box 100, which is suitable for power, chemical and other strong grounding scenarios.

[0120] As a specific implementation, the grounding nail 17 is located on the second outer side 16, that is, the grounding nail 17 and the caster wheel 161 are located on the same surface. This design makes the grounding nail 17 closer to the ground.

[0121] As another implementation, the grounding pin 17 is detachably connected to the housing 1. This design facilitates the disassembly and storage of the grounding pin 17 during transportation, and also makes it convenient to replace and maintain the grounding pin 17.

[0122] Specifically, the grounding nail 17 includes a body and a ground wire connected to the body, and the ground wire is installed on the second outer side 16 by a wing nut.

[0123] Specifically, the ground wire passes through the main enclosure 1 and the bracket assembly 12 to ensure a complete grounding connection.

[0124] In some embodiments, a folding handle 162 is provided on the first outer side 15 and the second outer side 16 respectively, and the folding handle 162 on the first outer side 15 avoids the opening and closing cover 11.

[0125] In the power box 100 provided in this embodiment of the utility model, folding handles 162 are provided on the first outer side 15 and the second outer side 16, so that users can lift or move the power box 100 from different directions, support two people to work together to move the heavy power box 100, and improve the convenience of users to move it.

[0126] It should be noted that the folding handle 162 on the first outer side 15 is positioned to avoid the opening and closing cover 11. This ensures that the opening and closing cover 11 will not be interfered with by the folding handle 162 when the storage chamber 13 is closed or exposed, so as to avoid mutual interference between the use of the folding handle 162 and the opening and closing cover 11 and ensure the functional integrity of the power supply box 100.

[0127] In this embodiment, when the folding handle 162 is in a fully folded state, it will not occupy too much space on the first outer side 15 and the second outer side 16, so as to make reasonable use of the space on the outer side of the box 1.

[0128] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
