Description

Technical Field

[0001] This invention relates to the field of electrical box technology, specifically to a building intelligent electrical box. Background Technology

[0002] Currently, electrical boxes are widely used in building power distribution systems to centrally install electrical components such as circuit breakers and meters. Existing electrical boxes typically achieve natural ventilation and heat dissipation by opening ventilation holes on the side walls of the box and installing dustproof nets. Some products will be equipped with cooling fans to enhance air circulation. Most of the components inside the box are directly fixed to the mounting back plate with bolts.

[0003] However, most existing electrical box ventilation holes are fixed structures, which cannot adjust the opening degree according to the temperature changes inside the box. This makes it difficult to achieve both heat dissipation efficiency and dust prevention. Moreover, the heat dissipation airflow path is mostly single, which can easily form heat dissipation dead zones inside the box, resulting in local overheating. In addition, electrical components are fixed to the inside of the electrical box with bolts. When inspecting and disassembling, it is necessary to reach into the electrical box and loosen the screws one by one, which results in low maintenance efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a building intelligent electrical box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a building intelligent electrical box, including an electrical box body, a set of ventilation mechanisms at both the left and right ends of the electrical box body, and a heat dissipation mechanism at the rear end of the electrical box body;

[0006] The components of the ventilation mechanism are all the same. The ventilation mechanism on the left includes a side opening, an opening and closing mechanism, a limiting frame and a filter mechanism. The left side of the electrical box is provided with a side opening. The left end of the side opening is provided with a set of opening and closing mechanisms. The right end of the opening and closing mechanism is provided with a set of limiting frames. The inner end of the limiting frame is connected to a set of filter mechanisms.

[0007] By adopting the above technical solution, the electrical enclosure can achieve side ventilation by using the ventilation mechanisms at both ends, and achieve overall heat dissipation in conjunction with the heat dissipation mechanism at the rear. The ventilation mechanism can realize the opening and closing control of the ventilation openings and airflow filtration. The overall ventilation and heat dissipation layout is reasonable, providing multiple ventilation and heat dissipation protections for the electrical enclosure.

[0008] Preferably, the opening and closing mechanism includes an inner frame, a linkage mechanism, and an opening and closing panel. An inner frame is provided on the left side of the side opening. A guide frame is provided on the right side of both the front and rear sides of the inner frame. A linkage mechanism is provided on the left side of each guide frame. At least two opening and closing panels are provided between the two sets of linkage mechanisms.

[0009] By adopting the above technical solution, the opening and closing mechanism can realize the linkage opening and closing of multiple sets of opening and closing panels by relying on the inner frame and linkage mechanism, control the opening and closing of the side opening, and use the guide frame as a motion limit guide to ensure the stability of the opening and closing of the panels and accurately control the ventilation effect.

[0010] Preferably, the components of the front and rear sets of linkage mechanisms are identical. The front linkage mechanism includes a hydraulic push rod, linkage arm one, linkage arm two, linkage arm three, linkage arm four, and a pressure plate. A set of hydraulic push rods is provided at the front top of the side opening. The pushing end of the hydraulic push rod is connected to a set of linkage arm one. Linkage arm one is located at the front top of the inner frame. At least two sets of linkage arm two are sequentially hinged to the bottom end of linkage arm one. A set of linkage arm three is hinged to the middle end of linkage arm one. At least two sets of linkage arm four are sequentially hinged to the bottom end of linkage arm three. A set of pressure plates is connected to the rear hinge points of linkage arm three and linkage arm four.

[0011] By adopting the above technical solution, the hydraulic push rod can drive the linkage arm one, linkage arm two, linkage arm three and linkage arm four to move together, realize the extension and retraction of linkage arm two, linkage arm three and linkage arm four, and simultaneously realize the opening and closing of the opening and closing panel. The driving power is stable, multiple linkage arms move in coordination, and the structural linkage is strong.

[0012] Preferably, the filtration mechanism includes a filter panel, a filter screen, and a pressure groove. A set of filter screens is provided at the middle of the filter panel, and pressure grooves for corresponding pressing plates are provided at both the front and rear ends of the side of the filter panel near the linkage mechanism.

[0013] By adopting the above technical solution, the filter screen on the filter panel can filter the ventilation airflow and effectively filter impurities in the air. The clamping plate and the pressure groove are used to position the filter panel, ensuring the installation stability of the filter panel within the limiting frame, ensuring the stable positioning of the filter mechanism, and preventing displacement and falling during use.

[0014] Preferably, the heat dissipation mechanism includes a bottom box, a bottom groove, a back groove, a top box, and a pop-out mechanism. The bottom surface of the electrical enclosure is provided with a set of bottom boxes, the inner end of the bottom plate of the electrical enclosure is provided with a bottom groove, the inner end of the back plate of the electrical enclosure is provided with a set of back grooves, the top of the electrical enclosure is provided with a set of top boxes, and the rear end of the electrical enclosure is provided with a set of pop-out mechanisms.

[0015] By adopting the above technical solution, the heat dissipation mechanism relies on the bottom groove, back groove and top box to form a heat dissipation channel from bottom to top, forming a complete air flow path. When the air flows, it can quickly remove the heat of the electrical box and improve the heat dissipation efficiency.

[0016] Preferably, a second set of filter screens is provided in the middle of the bottom box, a set of fans is provided at the top of the second set of filter screens, and the top of the bottom box is connected to the bottom groove through a connecting opening.

[0017] By adopting the above technical solution, the bottom box continuously draws air through the fan and introduces external air into the bottom tank through the connecting opening, thereby enhancing air circulation. At the same time, the second filter screen can effectively purify the air, ensuring that the air entering the bottom tank is clean and protecting the electrical components.

[0018] Preferably, the back groove is provided with no less than two sets of main air pipes, the upper and lower ends of the main air pipes are respectively connected to the top box and the bottom groove, and the front end of the main air pipes is provided with no less than two sets of auxiliary air pipes, the front end of the auxiliary air pipes extending through into the ejection mechanism.

[0019] By adopting the above technical solution, the main air pipe in the back slot connects the top box and the bottom slot to form an air flow channel. When the air flows, it can carry away excess heat. The auxiliary air pipe guides the air to the electrical component area, improving the heat dissipation effect on the electrical components, avoiding hot spot accumulation, and the heat dissipation is highly targeted.

[0020] Preferably, the pop-out mechanism includes a fixed back plate, fixed rods, limiting members, springs, contact rings, mounting panels, slots, and limiting guide grooves. A set of fixed back plates is provided at the rear end of the electrical box. A set of fixed rods is provided at each of the four ends of the front of the fixed back plate. A set of limiting members is hinged to the front end of each fixed rod. A set of springs is provided on the outside of each fixed rod. The rear end of each spring is connected to the fixed back plate. A set of contact rings is connected to the front end of each spring. A set of mounting panels is provided at the front end of the fixed back plate. Slots corresponding to the fixed rods are provided at each of the four ends of the mounting panel. Limiting guide grooves corresponding to the limiting members are provided at both the upper and lower ends of each slot.

[0021] By adopting the above technical solution, the mounting panel cooperates with the fixing rod through the slot, and the limiting component slides in the limiting guide groove, which can realize the fixed limiting of the back plate and the mounting panel, facilitate the quick limiting and disassembly of the mounting panel, and use the spring to provide pop-out force to drive the mounting panel forward, which is beneficial for the staff to inspect and maintain the electrical components on the mounting panel, and the operation is convenient.

[0022] Preferably, the limiting member has an inverted "T" shaped structure and its height is greater than the diameter of the fixing rod, and both the upper and lower ends of the limiting member extend into the limiting guide groove.

[0023] By adopting the above technical solution, the upper and lower ends of the limiting component can be stably embedded in the limiting guide groove, thereby achieving reliable limiting and locking of the mounting panel and avoiding problems such as the mounting panel falling off or shifting. At the same time, it can provide a smooth guiding effect during the pop-out and installation of the mounting panel, greatly improving the stability of the pop-out mechanism and the reliability of the limiting.

[0024] Preferably, the main air pipe has a continuous "S" shaped structure in the back groove, and the front end of the auxiliary air pipe is flush with the fixed back plate.

[0025] By adopting the above technical solution, the "S"-shaped main air pipe effectively extends the flow path and residence time of the heat dissipation airflow in the back groove, effectively improving the overall heat dissipation effect of the electrical enclosure. In addition, the front end of the auxiliary air pipe is flush with the fixed back plate, which can avoid the auxiliary air pipe from interfering with the pop-up and installation of the mounting panel. While ensuring accurate airflow delivery, it does not affect the normal operation of the pop-up mechanism, thus taking into account both heat dissipation efficiency and structural compatibility.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. This invention utilizes ventilation mechanisms located at both ends of the electrical enclosure. These mechanisms include side openings, opening and closing mechanisms, limiting frames, and filtering mechanisms. The opening and closing mechanisms employ hydraulic push rods to drive linked arms one, two, three, and four in coordinated motion, causing the opening and closing panel to move smoothly within the inner frame. This achieves precise control over the opening and closing degree of the side openings. Compared to the simple fixed ventilation openings or single baffle structures in existing technologies, the linked opening and closing design of the ventilation mechanism not only intelligently adjusts the ventilation volume according to the internal temperature but also securely presses the filtering panel within the limiting frame through the cooperation of the pressing plate and the pressing groove. This solves the problems of loose and easily displaced traditional filter installations, ensuring the long-term stability and reliability of the filtering mechanism.

[0028] 2. This invention constructs a complete three-dimensional air duct consisting of a bottom box, a bottom groove, a back groove, and a top box by using a heat dissipation mechanism located at the rear of the electrical enclosure. The fan purifies the external air through a second filter and sends it into the bottom groove. The air flows in the main air pipe with a continuous "S"-shaped structure and fully absorbs heat before finally being discharged from the front opening of the top box. Compared with the existing technology that only opens heat dissipation holes on the surface of the enclosure, the three-dimensional airflow duct constructed by the heat dissipation mechanism extends the airflow path and improves the heat exchange efficiency. At the same time, the auxiliary air pipe can accurately guide the cold air to the rear of the mounting panel to blow air onto the electrical component area, achieving targeted cooling of the core heat-generating components and effectively preventing the accumulation of local hot spots.

[0029] 3. This invention utilizes a pop-out mechanism located at the rear end of the electrical enclosure. A fixed rod with a limiting element is mounted on the fixed rear plate, along with a spring and a contact ring fitted around the outside of the fixed rod. When the mounting panel mates with the fixed rod via a slot, the inverted "T"-shaped limiting element is embedded in the limiting guide groove for reliable locking. When the panel is pressed, the limiting element disengages from the limiting guide groove, and the spring automatically pushes the mounting panel forward via the contact ring. Compared to the traditional method of installing electrical components at the inner rear end of the electrical enclosure, this pop-out mechanism achieves rapid disassembly and assembly, significantly simplifying the maintenance process and greatly improving the convenience of maintenance operations.

[0043] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0044] Please see Figures 1-2 This invention provides a building intelligent electrical box, including an electrical box body 1. A ventilation mechanism 2 is provided at both the left and right ends of the electrical box body 1, and a heat dissipation mechanism 3 is provided at the rear end of the electrical box body 1. The components of the ventilation mechanisms 2 are all identical. The left-end ventilation mechanism 2 includes a side opening 21, an opening and closing mechanism 22, a limiting frame 23, and a filtering mechanism 24. A side opening 21 is provided on the left side of the electrical box body 1, and an opening and closing mechanism 22 is provided at the left end of each side opening 21. The opening and closing degree of the opening and closing mechanism 22 can control the size of the side opening 21, facilitating the adjustment of the ventilation and heat dissipation effect of the electrical box body 1. A limiting frame 23 is provided at the right end of the opening and closing mechanism 22, and a filtering mechanism 24 is connected to the inner end of the limiting frame 23. The filtering mechanism 24 can filter the flowing air, ensuring the normal operation of the electrical components inside the electrical box body 1.

[0045] Specifically, the electrical enclosure 1 can achieve side ventilation by using the ventilation mechanisms 2 at both ends, and achieve overall heat dissipation in conjunction with the heat dissipation mechanism 3 at the rear. The ventilation mechanism 2 can realize the opening and closing control of the ventilation opening and airflow filtration. The overall ventilation and heat dissipation layout is reasonable, providing multiple ventilation and heat dissipation protections for the electrical enclosure 1.

[0046] Please see Figures 3-6 The opening and closing mechanism 22 includes an inner frame 221, a linkage mechanism 222, and an opening and closing panel 223. An inner frame 221 is provided at the left end of the left side opening 21. A guide frame 2211 is provided at the right end of both the front and rear sides of the inner frame 221. A linkage mechanism 222 is provided at the left end of each guide frame 2211. At least two opening and closing panels 223 are provided between the two sets of linkage mechanisms 222. The opening and closing panels 223 can be opened to cover the side opening 21 or retracted to expose the side opening 21 by the extension and retraction of the linkage mechanism 222. Ventilation grooves are provided on the surface of the opening and closing panels 223 so that the electrical box 1 still has basic ventilation function when the opening and closing panels 223 completely cover the side opening 21.

[0047] Specifically, the opening and closing mechanism 22, relying on the inner frame 221 and the linkage mechanism 222, can realize the linkage opening and closing of multiple sets of opening and closing panels 223, control the opening and closing of the side opening 21, and use the guide frame 2211 as a motion limit guide to ensure the stability of the opening and closing of the opening and closing panels 223 and accurately control the ventilation effect.

[0048] Please see Figures 4-6The components of the two sets of linkage mechanisms 222 are identical. The front linkage mechanism 222 includes a hydraulic push rod 2221, linkage arm one 2222, linkage arm two 2223, linkage arm three 2224, linkage arm four 2225, and a pressure plate 2226. A set of hydraulic push rods 2221 is located at the front top of the side opening 21. The pushing end of the hydraulic push rod 2221 is connected to a set of linkage arms one 2222. Linkage arm one 2222 is located at the front top of the inner frame 221. Linkage arm one 2222 has a zigzag structure, and the zigzag position is hinged to the inner top of the inner frame 221. When the hydraulic push rod 2221 pushes out, linkage arm one 2222 can rotate around the zigzag position. The opposite faces of the two sets of linkage arms one 2222 are respectively connected to the front and rear ends of a set of opening and closing panels 223, which can drive the opening and closing panels 223 to rotate synchronously. The bottom end of linkage arm one 2222 is sequentially hinged to no less than two sets of linkage arms two 2223. A set of linkage arms 2224 is hinged to the middle end of boom 1 2222. At least two sets of linkage arms 2225 are sequentially hinged to the bottom end of linkage arms 3 2224. Linkage arms 2223 and linkage arms 4 2225 are staggered and hinged to each other at the middle. The front and rear ends of the opening and closing panel 223 are connected to linkage arms 2223 or linkage arms 4 2225 located on the inner side. When boom 1 2222 rotates, it can drive linkage arms 2223 to rotate. The linkage arm 2224 drives the linkage arm 2225 to rotate, thereby enabling the retraction or extension of the linkage arm 2223 and the linkage arm 2225, thus controlling the opening and closing of the panel 223. The rear hinge points of the linkage arm 2224 and the linkage arm 2225 are connected to a set of pressure plates 2226. The end of the pressure plate 2226 extends to the front end of the filter mechanism 24 through the guide frame 2211, which can press the filter panel 241.

[0049] Specifically, the hydraulic push rod 2221 can drive the linkage arm 1 2222, linkage arm 2223, linkage arm 3 2224 and linkage arm 4 2225 to link together, realize the extension and retraction of linkage arm 2 2223, linkage arm 3 2224 and linkage arm 4 2225, and simultaneously realize the opening and closing of the opening and closing panel 223. The driving power is stable, multiple linkage arms move in coordination, and the structure has strong linkage.

[0050] Please see Figure 2 and Figure 7The filter mechanism 24 includes a filter panel 241, a filter screen 242, and a pressure groove 243. The top of the filter panel 241 can be inserted into the top of the limiting frame 23, and the bottom is connected to the bottom of the limiting frame 23 by a buckle to achieve a preliminary connection. The middle of the filter panel 241 is provided with a filter screen 242 for filtering air. The front and rear ends of the side of the filter panel 241 near the linkage mechanism 222 are provided with pressure grooves 243 corresponding to the pressing plates 2226. The ends of the pressing plates 2226 can extend into the pressure grooves 243 and move along the pressure grooves 243 to press the filter panel 241. The top of the pressure groove 243 is provided with a deepening groove. When the opening and closing mechanism 22 is fully retracted, the pressing plates 2226 all move into the deepening groove. At this time, the pressing effect on the filter panel 241 is poor. The bottom of the filter panel 241 can be pried out to disassemble and replace the filter panel 241.

[0051] Specifically, the filter screen 242 on the filter panel 241 can filter the airflow and effectively filter impurities in the air. It is positioned by the cooperation of the clamping plate 2226 and the pressure groove 243 to ensure the installation stability of the filter panel 241 within the limiting frame 23, and to ensure the stable positioning of the filter mechanism 24, so as to avoid displacement and falling during use.

[0052] Please see Figure 8 The heat dissipation mechanism 3 includes a bottom box 31, a bottom groove 32, a back groove 33, a top box 34, and a pop-out mechanism 35. A set of bottom boxes 31 are installed on the bottom surface of the electrical box 1. A bottom groove 32 is opened at the inner end of the bottom plate of the electrical box 1. A set of back grooves 33 is opened at the inner end of the back plate of the electrical box 1. A set of top boxes 34 are installed on the top of the electrical box 1. The front end of the top box 34 is designed with an open structure. When air flows from the bottom groove 32 and the back groove 33 into the top box 34, it can be discharged from the front opening of the top box 34, realizing the blowing effect on the top surface of the electrical box 1, improving the air flow path, and enhancing the heat dissipation effect of the electrical box 1. A set of pop-out mechanisms 35 is provided at the rear end of the electrical box 1 to facilitate the maintenance of electrical components by the staff.

[0053] Specifically, the heat dissipation mechanism 3 forms a heat dissipation channel from bottom to top by relying on the bottom groove 32, the back groove 33 and the top box 34, forming a complete air flow path. When the air flows, it can quickly remove the heat from the electrical box 1 and improve the heat dissipation efficiency.

[0054] Please see Figure 8 A set of air filter screens 311 is installed in the middle of the bottom box 31. A set of air-drawing fans 312 is provided at the top of the filter screens 311. The top of the bottom box 31 is connected to the bottom groove 32 through the connecting opening 313. The fans 312 can draw in air and discharge it into the bottom groove 32 after being filtered by the filter screens 311, so as to guide the air and facilitate the heat dissipation of the electrical box 1.

[0055] Specifically, the bottom box 31 continuously draws air through the fan 312 and introduces external air into the bottom tank 32 through the connecting opening 313 to enhance air flow. At the same time, the filter screen 311 can effectively purify the air, ensuring that the air entering the bottom tank 32 is clean and protecting the electrical components.

[0056] Please see Figures 8-9 The back slot 33 is equipped with at least two sets of main air pipes 331. The main air pipes 331 have a continuous "S"-shaped structure in the back slot 33, which can extend the air flow path and residence time, so as to remove more heat. The upper and lower ends of the main air pipes 331 are connected to the top box 34 and the bottom slot 32 respectively, which can guide the air in the bottom slot 32 to the top box 34. The front end of the main air pipes 331 is equipped with at least two sets of auxiliary air pipes 332. The front end of the auxiliary air pipes 332 extends through into the pop-up mechanism 35 and is flush with the fixed back plate 351. This can avoid the auxiliary air pipes 332 interfering with the pop-up and installation of the mounting panel 356. While ensuring accurate airflow delivery, it does not affect the normal operation of the pop-up mechanism 35, thus taking into account both heat dissipation efficiency and structural compatibility.

[0057] Specifically, the main air pipe 331 in the back slot 33 connects the top box 34 and the bottom slot 32 to form an air flow channel. When the air flows, it can carry away excess heat. The auxiliary air pipe 332 guides the air to the electrical component area, improving the heat dissipation effect on the electrical components, avoiding hot spot accumulation, and the heat dissipation is highly targeted.

[0058] Please see Figures 10-12The pop-out mechanism 35 includes a fixed rear plate 351, fixed rods 352, limiting members 353, springs 354, contact rings 355, mounting panel 356, slots 357, and limiting guide grooves 358. A set of fixed rear plates 351 is located at the rear end of the electrical housing 1. A set of fixed rods 352 is located at each of the four ends of the front of the fixed rear plate 351. A set of limiting members 353 is hinged to the front end of each fixed rod 352. The limiting members 353 have an inverted "T" shape and a height greater than the diameter of the fixed rods 352. Both the upper and lower ends of the limiting members 353 can extend into the limiting guide grooves 358, ensuring that the upper and lower ends of the limiting members 353 are stably embedded in the limiting guide grooves 358, achieving reliable limiting and locking of the mounting panel 356, preventing the mounting panel 356 from falling off or shifting. It also provides smooth guidance during the pop-out and installation of the mounting panel 356, significantly improving the stability of the pop-out mechanism 35's operation and the reliability of the limiting action. A set of springs 354 is sleeved on the outside of the rod 352. The rear end of the springs 354 is connected to the fixed back plate 351. A set of contact rings 355 is connected to the front end of the springs 354. A set of mounting panels 356 is provided at the front end of the fixed back plate 351. All electrical components are installed on the front end of the mounting panels 356. The upper and lower sides of the electrical housing 1 are provided with slide rails. The mounting panels 356 can slide back and forth along the slide rails. The four ends of the mounting panels 356 are provided with slots 357 corresponding to the fixed rod 352. The fixed back plate 351 can move backward to squeeze the contact rings 355 and the springs 354, and put the front end of the fixed rod 352 and the limiting member 353 into the slots 357. The upper and lower ends of the slots 357 are provided with limiting guide grooves 358 corresponding to the limiting member 353. The limiting guide grooves 358 are pentagonal in shape, and the end away from the fixed rod 352 is concave, which can lock the limiting member 353, thereby achieving the connection effect between the mounting panels 356 and the fixed back plate 351.

[0059] Specifically, the mounting panel 356 cooperates with the fixing rod 352 through the slot 357, and the limiting member 353 slides in the limiting guide groove 358, which can realize the fixed limiting of the back plate 351 and the mounting panel 356, which facilitates the quick limiting and disassembly of the mounting panel 356. In addition, the spring 354 provides a popping force, which can drive the mounting panel 356 to move forward, which is beneficial for the staff to inspect and maintain the electrical components on the mounting panel 356, and the operation is convenient.

[0060] This invention provides a building intelligent electrical box. Through ventilation mechanisms 2 located at both ends of the electrical box 1, the ventilation mechanism 2 includes components such as a side opening 21, an opening and closing mechanism 22, a limiting frame 23, and a filtering mechanism 24. The opening and closing mechanism 22 utilizes a hydraulic push rod 2221 to drive the coordinated movement of four linkage arms 2222, 2223, 2224, and 2225, causing the opening and closing panel 223 to move smoothly within the inner frame 221. This achieves precise control over the opening and closing degree of the side opening 21, compared to the simple fixed ventilation openings or single baffle structures in existing technologies. The linkage opening and closing design of this application can not only intelligently adjust the ventilation volume according to the internal temperature, but also firmly press the filter panel 241 into the limiting frame 23 through the cooperation of the pressing plate 2226 and the pressing groove 243. This solves the problem of loose installation and easy displacement of traditional filter screens, ensuring the stability and reliability of the filter mechanism 24 in long-term use. Through the heat dissipation mechanism 3 set at the rear of the electrical box 1, a complete three-dimensional air duct composed of bottom box 31, bottom groove 32, back groove 33 and top box 34 is constructed. The fan 312 sends the outside air into the bottom groove 32 after being purified by the second filter screen 311. The air continuously "S" The air flows through the main air duct 331 of the three-dimensional structure, fully absorbing heat, and finally exits from the front opening of the top box 34. Compared with the existing technology that only opens heat dissipation holes on the surface of the box, the three-dimensional airflow duct constructed in this application extends the airflow path and improves the heat exchange efficiency. At the same time, the auxiliary air duct 332 can precisely guide the cold air to the rear end of the mounting panel 356 to blow air onto the electrical component area, realizing targeted cooling of the core heat-generating components and effectively preventing the accumulation of local hot spots. Through the pop-out mechanism 35 set in the rear end of the electrical box 1, a fixing device with a limiting member 353 is set on the fixed rear plate 351. The rod 352, along with the spring 354 and contact ring 355 sleeved on the outside of the fixed rod 352, allow the mounting panel 356 to mate with the fixed rod 352 via the slot 357. The inverted "T"-shaped limiting member 353 is embedded in the limiting guide groove 358 for reliable locking. When the panel is pressed, the limiting member 353 disengages from the limiting guide groove 358, and the spring 354 automatically pushes the mounting panel 356 forward via the contact ring 355. Compared to the traditional electrical box method of installing electrical components at the inner rear end, the pop-out mechanism 35 achieves rapid disassembly and assembly, significantly simplifying the maintenance process and greatly improving the convenience of maintenance operations.
