Description

Technical Field

[0001] This application relates to the field of electrical box technology, and in particular to an electrical box that is easy to maintain later. Background Technology

[0002] An electrical box is a device that assembles switching equipment, testing instruments, and auxiliary equipment in a closed or semi-closed metal enclosure according to electrical wiring requirements, allowing staff to quickly perform data testing and control closure of multiple circuits.

[0003] One type of electrical box includes an outer casing and a mounting plate. The mounting plate is fixed inside the electrical box. Workers fix the switching equipment, testing instruments and auxiliary equipment on the mounting plate and organize and fix the wires connecting the various devices.

[0004] However, existing electrical boxes have complex internal wiring and dense equipment, leaving insufficient space for staff to perform maintenance on the inside of the box. Utility Model Content

[0005] To address the issue of insufficient space inside the electrical box for subsequent maintenance, this application provides an electrical box that facilitates later maintenance.

[0006] This application provides an electrical box that facilitates later maintenance, and adopts the following technical solution:

[0007] An electrical box that facilitates later maintenance includes:

[0008] The electrical box body is fixedly installed on the ground. Multiple sets of wire holes are spaced apart on the electrical box body. Multiple sets of mounting brackets are horizontally fixed on the electrical box body.

[0009] Side panels are rotatably mounted on the periphery of the electrical box body via hinges, and two sets of side panels are symmetrically arranged along the center line of the electrical box body in the height direction.

[0010] The fixing component is fixedly installed on the side panel near the main body of the electrical box, and the fixing component fixes the side panel and the main body of the electrical box in a fixed connection.

[0011] The protective door has one end connected to the side panel away from the main body of the electrical box via a hinge.

[0012] By adopting the above technical solution, the main body of the electrical box provides installation space for the side panels. The mounting bracket facilitates the installation of switches, testing instruments, and auxiliary equipment inside the electrical box. The wiring holes facilitate the connection of various devices inside the electrical box to external circuits. The side panels are rotatably connected to the main body of the electrical box via hinges, and the protective door is also rotatably connected to the side panels via hinges, allowing staff to open the electrical box for preliminary inspection of the equipment's operating status. The fixing components securely connect the side panels to the main body of the electrical box, enabling staff to control the opening and closing of the side panels. This facilitates opening the side panels during maintenance, thereby increasing the operating space inside the electrical box and improving maintenance efficiency.

[0013] Optional, fixed components include:

[0014] Mounting plate, which is vertically fixed on the main body of the electrical box. Mounting plate is provided with mounting holes, and multiple sets of mounting holes are arranged at intervals along the length of the mounting plate.

[0015] A rotating rod is fixedly mounted on the side plate, with the rotating rod corresponding to the mounting hole.

[0016] The fixed block is rotatably connected to the end of the rotating rod away from the side plate.

[0017] By adopting the above technical solution, when the staff controls the side plate to rotate to fit with the main body of the electrical box, the rotating rod can drive the fixing block to pass through the mounting hole and extend into the interior of the electrical box. The staff can rotate the fixing block so that the fixing block forms a certain angle with the mounting hole and cannot leave the mounting hole, thereby achieving the purpose of fixing the side plate to the main body of the electrical box.

[0018] Optionally, multiple sets of inclined beams are fixedly installed on the main body of the electrical box at an angle.

[0019] By adopting the above technical solution, the setting of the inclined beam can improve the connection strength between the main body of the electrical box and the mounting frame, and improve the installation stability of various equipment on the mounting frame.

[0020] Optionally, an electrostatic grounding rod may be fixedly installed on the main body of the electrical box.

[0021] By adopting the above technical solution, the installation of the electrostatic grounding rod can conduct static electricity on the main body of the electrical box to the ground, avoiding the accumulation of static electricity from interfering with or damaging the internal equipment of the electrical box, and also reducing the probability of static electricity adsorbing dust in the air onto the surface of the main body of the electrical box.

[0022] Optionally, a cooling fan is fixedly installed on the side panel.

[0023] By adopting the above technical solution, the cooling fan can dissipate heat from the device, reduce the probability of equipment failure or damage caused by excessive internal temperature of the electrical box, and extend the service life of the electrical box.

[0024] Optionally, the protective door is equipped with a transparent panel.

[0025] By adopting the above technical solution, the transparent panel allows staff to observe the operating status of the equipment inside the electrical box in real time.

[0026] Optionally, a friction pad is fixedly installed on the side of the fixing block near the side plate, and the friction pad is made of rubber.

[0027] By adopting the above technical solution, the friction pad can increase the friction between the fixing block and the side plate, thereby enhancing the fixing stability of the fixing component on the side plate.

[0028] Optionally, two sets of friction pads are symmetrically arranged along the center of the rotating rod axis.

[0029] By adopting the above technical solution, the two sets of friction pads are symmetrically distributed in the center, which increases the contact area between the friction pads and the side plate, so that the fixing block can more stably press the side plate when rotating.

[0030] Optionally, the hinge is a hinge.

[0031] By adopting the above technical solution, the hinge design allows the side panel to open and close flexibly while maintaining the installation stability of the side panel and the protective door.

[0032] In summary, this utility model embodiment provides an electrical box that facilitates later maintenance, including at least one of the following beneficial technical effects:

[0033] 1. The main body of the electrical box is designed with side panels providing installation space. The mounting brackets facilitate the installation of switches, testing instruments, and auxiliary equipment inside the box. The wiring holes allow for easy connection of various devices inside the box to external circuits. The side panels are rotatably connected to the main body of the box via hinges, as are the protective doors. This allows staff to open the box for preliminary inspection of the equipment's operating status. The fixing components securely connect the side panels to the main body, enabling staff to control the opening and closing of the side panels. This increases the operating space inside the box and improves maintenance efficiency.

[0034] 2. The installation of an electrostatic grounding rod can conduct static electricity from the main body of the electrical box to the ground, preventing static electricity accumulation from interfering with or damaging the internal equipment of the electrical box, and also reducing the probability of static electricity attracting dust from the air to the surface of the electrical box.

[0042] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0043] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 This application discloses an electrical box that facilitates later maintenance, including: an electrical box body 21, a side plate 22, a fixing component 1, and a protective door 23; the electrical box body 21 is fixedly installed on the ground, and multiple sets of wire holes 31 are spaced apart on the electrical box body 21. Multiple sets of mounting brackets 26 are horizontally fixed on the electrical box body 21. The side plate 22 is rotatably installed on the periphery of the electrical box body 21 through a hinge 30. Two sets of side plates 22 are symmetrically arranged along the center line of the height direction of the electrical box body 21. The fixing component 1 is fixedly installed on the side of the side plate 22 close to the electrical box body 21. The fixing component 1 fixes the side plate 22 and the electrical box body 21. One end of the protective door 23 is rotatably connected to the end of the side plate 22 away from the electrical box body 21 through the hinge 30.

[0044] In this embodiment, the electrical box body 21 is U-shaped, with the open end of the electrical box body 21 pointing horizontally towards the worker. Multiple sets of wiring holes 31 are provided at the end of the electrical box body 21 furthest from the open end to facilitate cable introduction and wiring connections between various devices. A static grounding rod 25 is fixedly installed at the end of the electrical box body 21 furthest from the open end. The worker can connect the static grounding rod 25 to the ground via a line, thereby effectively dissipating static electricity from the electrical box body 21, reducing the risks associated with static electricity on the surface of the electrical box body 21, and also reducing static electricity on the electrical box body 21. The adsorption of dust in the air improves the cleanliness of the electrical box body 21, reducing the frequency of maintenance and cleaning by staff. The electrostatic grounding rod 25 can be welded to the electrical box body 21 or integrally formed; no specific limitation is made in this embodiment. The mounting bracket 26 is rectangular and provides installation space for the equipment inside the electrical box. The side plates 22 are also rectangular, with two sets of side plates 22 rotatably mounted on both sides of the electrical box body 21 along its length. Each set of side plates 22 is rotatably connected to the electrical box body 21 via multiple sets of hinges 30. The hinge 30 is a hinge, and multiple hinges can improve the installation stability between the side plate 22 and the main body 21 of the electrical box, without affecting the rotation of the side plate 22 and the main body 21 of the electrical box. A cooling fan 27 is fixedly installed on the side plate 22. When the cooling fan 27 is turned on, it can blow air into the electrical box, effectively reducing the internal temperature of the electrical box and reducing the probability of abnormal operation or accelerated aging of the equipment installed in the electrical box due to high temperature. The protective door 23 is set in a cuboid shape. The operator can close the electrical box through the protective door 23, making the electrical box a sealed space and reducing the impact of the external environment on the equipment inside the electrical box. To mitigate the impact of the electrical box's internal structure, a transparent panel 28 is installed on the protective door 23. The transparent panel 28 is rectangular, allowing staff to observe the operating status of the equipment inside the electrical box without frequently opening the protective door 23. Staff can fix the electrical box body 21 and the side panel 22 by controlling the fixing component 1, preventing the side panel 22 and the electrical box body 21 from rotating. When maintenance is required inside the electrical box, staff can release the fixing component 1, allowing the side panel 22 to rotate and open, facilitating the inspection and maintenance of the equipment inside the electrical box.

[0045] In practical use, the operator fixes the switching equipment, testing instruments, and auxiliary equipment on the mounting frame 26. The operator then passes the cables through the wiring holes 31 and connects them to the various devices on the mounting frame 26 according to the electrical wiring requirements. The operator connects the static grounding rod 25 to the ground through a line. The operator fixes the side plate 22 to the main body 21 of the electrical box using the fixing component 1. The operator starts the cooling fan 27 to dissipate heat from the inside of the electrical box. The operator closes the protective door 23. When the electrical box needs to be maintained, the operator opens the protective door 23 and controls the fixing component 1 inside the electrical box to release the fixation between the side plate 22 and the main body 21. This allows the two sets of side plates 22 to rotate 90 degrees away from the main body 21, opening the front and sides of the main body 21 completely, facilitating a comprehensive inspection and maintenance of the equipment inside the electrical box.

[0046] Combination Figure 3 and Figure 4 In one specific embodiment, the fixing component 1 includes: a mounting plate 11, a rotating rod 12, and a fixing block 13; the mounting plate 11 is vertically fixed on the electrical box body 21, and the mounting plate 11 is provided with mounting holes 32, and multiple sets of mounting holes 32 are spaced apart along the length of the mounting plate 11; the rotating rod 12 is fixedly installed on the side plate 22, and the rotating rod 12 is correspondingly arranged with the mounting holes 32; the fixing block 13 is rotatably connected to the end of the rotating rod 12 away from the side plate 22.

[0047] In this embodiment, the mounting plate 11 is rectangular, and four sets of mounting plates 11 are fixedly installed along the four edges of the electrical box body 21 in the width direction. The mounting plate 11 and the electrical box body 21 can be welded or integrally formed; no specific limitation is made in this embodiment. The mounting hole 32 is an oblong hole. Multiple sets of inclined beams 24 are obliquely fixed on the electrical box body 21. The inclined beams 24 are X-shaped and are interlocked and fixed to the electrical box body 21, thus fixing the electrical box body 21 and the mounting frame 26 together. The X-shaped structure of the inclined beams 24 enhances the support stability of the mounting frame 26 and extends the service life of the electrical box. Service life; the rotating rod 12 is cylindrical. When the operator controls the side plate 22 to rotate to a position where it fits against the electrical box body 21, the rotating rod 12 extends precisely to the center of the mounting hole 32. Each set of mounting holes 32 corresponds to a set of rotating rods 12. The fixing block 13 is cuboid. The rotating rod 12 is rotatably connected to the center of the fixing block 13. The width of the fixing block 13 is smaller than the width of the mounting hole 32, and the length of the fixing block 13 is smaller than the length of the mounting hole 32. There is friction between the fixing block 13 and the rotating rod 12. Only when the operator applies pressure to the fixing block 13 can the fixing block 13 rotate around the rotating rod 12. When rotated, the initial state of the fixed block 13 is horizontal. When the operator controls the rotating rod 12 to extend to the center position of the mounting hole 32, the fixed block 13 just passes through the mounting hole 32 and extends into the electrical box. A friction pad 29 is fixedly installed on the side of the fixed block 13 near the side plate 22. The friction pad 29 is made of rubber and is arranged in a trapezoidal shape. One end of the long side of the friction pad 29 extends from the fixed block 13 into the mounting hole 32, while the other end of the short side does not extend from the fixed block 13 into the mounting hole 32. Two sets of friction pads 29 are symmetrically arranged along the axis of the rotating rod 12. When the operator rotates the fixed block 12... When block 13 is in operation, the rotation of fixed block 13 causes friction pad 29 to rotate synchronously. The inclined edge of friction pad 29 abuts against the inner wall of mounting hole 32, causing friction pad 29 to deform and gradually embed into the gap between fixed block 13 and mounting plate 11. After elastic deformation, friction pad 29 needs to return to its original shape, thus generating a reverse force on fixed block 13, further enhancing the friction between fixed block 13 and mounting plate 11. Fixed block 13 drives friction pad 29 from a horizontal state to a vertical state, making fixed block 13 unable to detach from mounting hole 32, thereby achieving the purpose of fixing side plate 22 to electrical box body 21.

[0048] In practical use, after the operator rotates the side plate 22 to a position where it fits against the main body 21 of the electrical box, the rotating rod 12 drives the fixing block 13 to extend through the mounting hole 32 into the interior of the electrical box. The operator controls the fixing block 13 to rotate from a horizontal state to a vertical state. The rotation of the fixing block 13 causes the friction pad 29 to embed into the gap between the mounting plate 11 and the fixing block 13, so that the fixing block 13 and the mounting plate 11 fit tightly together, thereby fixing the side plate 22 and the main body 21 of the electrical box. When the operator needs to maintain the interior of the electrical box, the operator controls the fixing block 13 to continue rotating and turn it to a horizontal state. The operator rotates the side plate 22 in a direction away from the main body 21 of the electrical box. The rotation of the side plate 22 causes the rotating rod 12 and the fixing block 13 to disengage from the mounting hole 32, thereby releasing the component from the fixation between the side plate 22 and the main body 21 of the electrical box.

[0049] The implementation principle of this application is as follows: Workers fix the switching equipment, testing instruments, and auxiliary equipment onto the mounting frame 26. Workers then pass the cables sequentially through the wiring holes 31 and connect them to the various devices on the mounting frame 26 according to electrical wiring requirements. Workers connect the static grounding rod 25 to the ground via a line. Workers control the side plate 22 to rotate until it is flush with the main body 21 of the electrical box. The rotation of the side plate 22 causes the rotating rod 12 and the fixing block 13 to pass through the mounting holes 32 and extend into the electrical box. Workers rotate the fixing block 13, causing it to change from a horizontal to a vertical position. The rotation of the fixing block 13 causes the friction pad 29 to embed into the mounting box. The gap between the mounting plate 11 and the fixing block 13 allows the fixing block 13 to fit tightly against the mounting plate 11, thereby fixing the side plate 22 and the electrical box body 21. When the staff needs to maintain the inside of the electrical box, the staff controls the fixing block 13 to continue rotating to a horizontal position, and the staff drives the side plate 22 to rotate away from the electrical box body 21. The rotation of the side plate 22 causes the rotating rod 12 and the fixing block 13 to disengage from the mounting hole 32, thereby releasing the fixed connection between the side plate 22 and the electrical box body 21. The front end and both sides of the electrical box body 21 are fully opened, which facilitates the staff to conduct a comprehensive inspection and maintenance operation on the equipment inside the electrical box.

[0050] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
