Description

Technical Field

[0001] This utility model relates to an electrical engineering device, and more particularly to a concealed junction box for electrical engineering. Background Technology

[0002] In electrical engineering, concealed junction boxes are common components used to hide wires and protect wire connections. Traditional junction boxes are usually fixed inside walls, requiring precise control of the wall groove dimensions during installation to ensure proper mounting. However, this method has several problems, such as the difficulty in precisely controlling the wall groove dimensions, leading to difficult or insecure installation, and a cumbersome and inefficient installation process. Furthermore, traditional junction boxes are not easily adjustable after installation; if the wall groove dimensions are no longer suitable, re-grooving is necessary, increasing construction costs and time. Therefore, developing an easy-to-install, adjustable, and secure concealed junction box for electrical engineering is of significant practical importance. Summary of the Invention

[0003] The purpose of this utility model is to provide a concealed junction box for electrical engineering.

[0004] To achieve the above objectives, this utility model is implemented according to the following technical solution:

[0005] This utility model includes an engineering junction box body. The engineering junction box body has inlet and outlet holes and threaded holes for connecting decorative panels on two opposite sides. Support components are provided on the other two opposite sides of the engineering junction box body. The support components are connected to the engineering junction box body through a drive mechanism.

[0006] Furthermore, the support component is a box mounting support plate, one side of which is rotatably connected to the bottom edge of the engineering junction box body, and the inner center of the box mounting support plate is connected to the engineering junction box body through the drive mechanism.

[0007] Specifically, the driving mechanism includes a support mechanism mounting through hole, a support mechanism driving screw, a driving screw mounting seat, a movable nut seat, and a support plate driving link. The support mechanism mounting through hole is located on the side wall of the engineering junction box body. There are two driving screw mounting seats, which are fixedly installed on the inner side of the engineering junction box body and located near the support mechanism mounting through hole. Both ends of the support mechanism driving screw are rotatably connected to the two driving screw mounting seats. The movable nut seat is fitted onto the middle section of the support mechanism driving screw and is threadedly engaged with the support mechanism driving screw. One side of the movable nut seat is rotatably connected to one end of the support plate driving link, and the other end of the support plate driving link passes through the support mechanism mounting through hole and is rotatably connected to the inner center of the box mounting support plate.

[0008] The beneficial effects of this utility model are:

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0014] like Figure 1 and 2As shown: This utility model includes an engineering junction box body 1. The engineering junction box body 1 has inlet / outlet holes and threaded holes for connecting decorative panels on two opposite sides. Support components are provided on the other two opposite sides of the engineering junction box body 1. The support components are connected to the engineering junction box body 1 via a drive mechanism. The support plate can be extended or retracted by rotating with the bottom edge of the engineering junction box body. The drive mechanism includes a support mechanism mounting through hole, a support mechanism drive screw, a drive screw mounting seat, a movable nut seat, and a support plate drive connecting rod. The rotation of the screw drives the movable nut seat to move up and down, thereby pushing the support plate drive connecting rod to achieve the extension or retraction of the support plate. This design allows the junction box to adapt to wall grooves of different sizes, improving installation flexibility and applicability.

[0015] Furthermore, the support component is a box mounting support plate 2, one side of which is rotatably connected to the bottom edge of the engineering junction box body 1, and the inner middle part of the box mounting support plate 2 is connected to the engineering junction box body 1 through the drive mechanism.

[0016] Specifically, the driving mechanism includes a support mechanism mounting through hole 3, a support mechanism driving screw 4, a driving screw mounting seat 5, a movable nut seat 6, and a support plate driving connecting rod 7. The support mechanism mounting through hole 3 is located on the side wall of the engineering junction box body 1. There are two driving screw mounting seats 5, which are fixedly installed on the inner side of the engineering junction box body 1 and located near the support mechanism mounting through hole 3. The two ends of the support mechanism driving screw 4 are rotatably connected to the two driving screw mounting seats 5. The movable nut seat 6 is fitted into the middle section of the support mechanism driving screw 4 and is threadedly engaged with the support mechanism driving screw 4. One side of the movable nut seat 6 is rotatably connected to one end of the support plate driving connecting rod 7. The other end of the support plate driving connecting rod 7 passes through the support mechanism mounting through hole 3 and is rotatably connected to the inner middle of the box mounting support plate 2. The drive screw mounting base is fixed to the inside of the junction box body. The two ends of the support mechanism drive screw are rotatably connected to the two drive screw mounting bases. The movable nut seat is threadedly engaged with the support mechanism drive screw. This structural design allows the rotation of the screw to be effectively converted into the extension and retraction of the support plate. Operation is simple; the extension and retraction of the support plate can be achieved simply by adjusting the support mechanism drive screw with a screwdriver, improving installation efficiency.

[0017] The working principle of this utility model is as follows:

[0018] When using this invention, an installation recess is chiseled out during electrical engineering construction on the wall. The device of this invention is then placed into the wiring position within the recess. To facilitate installation, the recess is often made relatively large, which can be difficult to control, especially on brick walls. With this invention, the support mechanism is adjusted using a screwdriver to drive the screw 4, thereby adjusting the movable nut seat 6 to move up and down. As the movable nut seat 6 moves up and down, it drives the support plate drive linkage 7 to push out or retract the upper side of the box mounting support plate 2. Because the edges of the box mounting support plate 2 are rotatably connected, an inverted triangular structure is formed, and its size is adjustable, allowing for secure installation in recesses of different sizes. Finally, cement is filled into the box mounting support plate 2 to further enhance its stability. One end of the support plate drive linkage is connected to the movable nut seat, and the other end passes through the support mechanism's mounting through hole and rotatably connects to the inner center of the box mounting support plate, forming an inverted triangular structure. This structural design allows the support plate to stably support the junction box body. With its compact structure, the junction box is flush with the wall after installation, which is aesthetically pleasing and saves space. At the same time, the junction box is securely installed, improving its stability and safety. During electrical engineering construction on the wall, the upper side of the box mounting support plate can be pushed out or retracted by adjusting the drive screw of the support mechanism to accommodate grooves of different sizes. Then, cement is filled into the box to further enhance its stability.

[0019] The junction box of this invention is easy to install, adjustable, and sturdy and stable, suitable for the concealed wiring needs of various electrical engineering projects, improving construction efficiency and extending the service life of the junction box.
