Description

Technical Field

[0001] This utility model relates to the field of junction box technology, and in particular to a stackable, height-increasing 86-type junction box. Background Technology

[0002] The 86-type junction box is a standard specification for junction boxes, with a width and height of 86 millimeters. This is an industry standard in electrical installation. The 86-type junction box is commonly used for wiring installations in households, such as installing switches and sockets. The depth of the 86-type junction box typically includes 5cm / 6cm / 7cm. During the installation of electrical wiring in a house, a groove is cut into the wall to install the junction box. Usually, the opening of the junction box is almost flush with the groove. After the wall surface is painted, the switch or socket cover is installed, and it appears to be almost flush with the wall. However, with modern interior design, wood veneer panels, sound insulation, or impact-resistant soft padding are often installed on the walls. These materials have a certain thickness, causing the height of the junction box opening relative to the surface of these decorative panels to increase significantly compared to the original height of the junction box opening relative to the actual wall surface. This makes it impossible to directly install the switch or socket panel into the junction box, or if forced, the switch or socket panel will not fit within the opening of these decorative panels, resulting in an unsightly appearance. To address this, existing technology discloses a retractable and easy-to-install 86-type base box (patent publication number CN205141575U). This technical solution discloses a base box and a telescopic box, with slides and grooves respectively provided on the base box and the telescopic box, allowing the telescopic box to extend and retract within the base box. The telescopic box can be pulled out and adjusted according to the distance between the panel and the base box, facilitating panel installation on the telescopic box. However, this existing technology has a relatively complex structure and high production costs. Furthermore, its extension beyond the limit cannot meet the requirements for further height differences, thus exhibiting certain limitations. Therefore, there is still room for further improvement in existing base box height-increasing technologies. Utility Model Content

[0003] In view of this, this utility model proposes a stackable height-adjustable 86-type junction box. By designing compatible stackable height-adjustable components, the required number of height-adjustable components can be stacked as needed to adjust to a suitable height, thereby breaking the upper limit of height adjustment and making it more conducive to meeting the needs of various decoration and construction.

[0004] The technical solution disclosed in this utility model is a stackable height-adjustable 86-type wiring box, including a box body and stackable height-adjustable components. The upper port edge of the box body is provided with a first snap-fit ​​end. The stackable height-adjustable component includes a hollow frame. The lower port of the hollow frame is provided with a flange for tightly fitting into the upper port of the box body. The outer wall of the flange and the lower port of the hollow frame form a step. A second snap-fit ​​end is provided on the step. The upper port edge of the stackable height-adjustable component is provided with a third snap-fit ​​end with the same structure as the first snap-fit ​​end. When the stackable height-adjustable components are stacked on the box body, the second snap-fit ​​end and the first snap-fit ​​end are tightly fitted together. When multiple stackable height-adjustable components are stacked, the second snap-fit ​​end of the previous stackable height-adjustable component and the third snap-fit ​​end of the next stackable height-adjustable component are tightly fitted together, and the flange of the previous stackable height-adjustable component is tightly fitted into the upper port of the next stackable height-adjustable component.

[0005] Furthermore, the first snap-fit ​​end is provided with at least two snap-fit ​​slots on the inner side of the port edge opposite the upper port of the bottom box body, and the second snap-fit ​​end is provided with snap-fit ​​protrusions on the outer side of the port edge opposite the lower port of the hollow frame body, which are respectively snap-fit ​​protrusions that engage with the snap-fit ​​slots.

[0006] Furthermore, the slot is a U-shaped slot, with the U-shaped slot having an opening facing the inner side and upper end of the bottom box body. A first snap-fit ​​protrusion is provided on the opposite wall of the U-shaped slot near the upper opening. The snap-fit ​​protrusion is a U-shaped protrusion, and a second snap-fit ​​protrusion is provided on the opposite sides of the U-shaped protrusion. The first and second snap-fit ​​protrusions are curved protrusions. The U-shaped protrusion is inserted into the U-shaped slot, and the second snap-fit ​​protrusion and the first snap-fit ​​protrusion achieve snap-fit ​​limiting.

[0007] Furthermore, on the two opposite sides of the upper port of the bottom box body, one side is provided with a first splicing end and the other side is provided with a second splicing end. The first splicing end and the second splicing end are used for splicing between multiple bottom box bodies.

[0008] Furthermore, the first splicing end is provided with a cylinder at each of the outer ends of the upper port edge of the bottom box body, and one side of the cylinder is integrally connected to the outer wall of the bottom box body. The edge of the bottom box body is provided with an insertion interface corresponding to the upper end of the cylinder. The second splicing end is provided with an outward-facing C-shaped groove snap-fit ​​part at each of the outer ends of the upper port edge of the bottom box body opposite to the first splicing end.

[0009] Furthermore, each side wall of the bottom box body is provided with two knockout holes, and a knockout hole is provided in the center of the bottom wall of the bottom box body.

[0010] Furthermore, the inner sidewalls of the bottom box body are provided with a mounting and fixing position perpendicular to the bottom wall at the middle position of the two opposing inner sidewalls, and the inner frame wall of the hollow frame is provided with a docking hole that is connected to the mounting and fixing position.

[0011] This application proposes a stackable, height-adjustable 86-type junction box. Its advantage lies in the fact that, through the design of compatible stackable extension components, the number of extension components can be increased as needed. This accommodates different height differences between the finished wall surface and the wall caused by various wall surface decoration designs. The depth of the junction box is increased by stacking extension components, and then the button panel or socket panel is snapped onto the top stacked extension component. Compared to existing telescopic junction box designs, whose height is limited by the maximum stretching distance, this solution allows for the arbitrary stacking of the required number of extension components to meet various usage needs, thus breaking the upper limit of junction box height and better meeting the requirements of various decoration and construction methods.
