[0004] In existing technologies, junction boxes are usually exposed on the outside of the wall, which is not aesthetically pleasing. At the same time, junction boxes are inconvenient to disassemble and install during installation and wiring. To address this, we propose a concealed quick-access side junction box. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a hidden quick side junction box that can be hidden inside the wall and integrated with the surrounding environment. It can facilitate disassembly and installation during wiring and can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a concealed quick-access side junction box, comprising a pre-embedded box, a box assembly, an internal sealing assembly, and an external sealing assembly;

[0007] Embedded box: Four bolt fixing holes are opened at the four corners of the upper end. The upper end of the embedded box is equipped with a box body assembly and an external sealing assembly. The upper end of the box body assembly is equipped with an internal sealing assembly.

[0008] The enclosure assembly includes an inner enclosure mounting slot, a junction box inner enclosure, limiting strips, limiting grooves, permanent magnet one, and permanent magnet two. The inner enclosure mounting slot is provided on the inner side of the pre-embedded enclosure. Two limiting strips are fixedly connected to the middle of the upper and lower ends of the outer side of the junction box inner enclosure. Two limiting grooves are provided at the middle of the front and rear ends of the inner side of the inner enclosure mounting slot. The junction box inner enclosure is slidably connected to the inner side of the inner enclosure mounting slot. The limiting strips are slidably connected to the inner side of the limiting grooves. Four permanent magnet two are embedded in the four corners of the lower end of the junction box inner enclosure. Four permanent magnet one are embedded in the four corners of the inner side of the inner enclosure mounting slot.

[0009] The embedded box is installed on the wall through bolt fixing holes. The upper part integrates the box assembly and the external sealing assembly. The internal sealing assembly is installed on the top of the box assembly, forming a layered sealing system. The modular design simplifies the installation process. The embedded box provides a stable base. Multiple components work together to achieve double protection inside and outside. The box assembly slides with the junction box inner box through the inner box mounting groove. The limit strip moves along the limit groove. Permanent magnet one and permanent magnet two magnetically fix the position of the inner box. The limit structure prevents displacement. The magnetic attraction enables quick disassembly and assembly, improving the convenience of maintenance.

[0010] Furthermore, the enclosure assembly also includes wiring mounting holes, a rubber blocking plate, and external wiring mounting holes. Multiple external wiring mounting holes are correspondingly formed at the left and right ends of the inner side of the inner enclosure mounting slot, and multiple wiring mounting holes are correspondingly formed at the left and right ends of the inner side of the junction box inner enclosure. The wiring mounting holes correspond in position to the external wiring mounting holes, and the rubber blocking plate is slidably connected to the wiring mounting holes and the external wiring mounting holes. The wiring mounting holes and the external wiring mounting holes are aligned to form a wire passage. The rubber blocking plate slides to seal unused holes. The rubber blocking plate is waterproof and dustproof, and the double-row holes adapt to multiple cable layouts, offering high flexibility.

[0011] Furthermore, the internal sealing assembly includes a sealing plate, a mounting box, a gear, a sliding strip, a rack, a telescopic rod, a spring, a rotating handle, and a circular mounting groove. The mounting box is fixedly connected to the lower end of the sealing plate. Two sliding strips are slidably connected to the inner side of the mounting box. One end of each sliding strip passes through the mounting box, and a rack is fixedly connected to the inner side of each sliding strip. A telescopic rod is fixedly connected to the other end of each sliding strip. A spring is sleeved on the outer side of the telescopic rod, and the other end of the spring is fixedly connected to the mounting box. A gear is rotatably connected to the center of the inner side of the mounting box, and the gear meshes with the rack. A circular mounting groove is formed at the upper end of the sealing plate, and a rotating handle is rotatably connected to the inner side of the circular mounting groove. The rotating handle meshes with the gear. Rotating the rotating handle drives the gear to move the rack, causing the sliding strip to extend outward. The spring and telescopic rod buffer and reset, and the spring latch engages in the spring latch groove for locking. The gear and rack transmission are precise, and the automatic locking of the spring latch enhances sealing performance, making operation effortless.

[0012] Furthermore, the internal sealing assembly also includes a spring and a spring groove. A spring is fixedly connected to the outer side of the sliding bar. The outer side of the spring is triangular. Two spring grooves are formed in the middle of the upper left and right ends of the inner side of the junction box.
