Description

A concealed junction box for building electrical systems Technical Field

[0001] This utility model belongs to the field of building electrical technology, and in particular relates to a concealed junction box for building electrical applications. Background Technology

[0002] Concealed junction boxes, also known as hidden junction boxes, are building electrical components used to hide electrical wires and improve the aesthetics and safety of a space. They are usually embedded in the wall during building construction or decoration. The installation of concealed junction boxes usually requires the use of an electric drill and grooving tools to cut a suitable groove in the wall, then placing the concealed junction box in the groove, and finally filling and fixing it with cement mortar.

[0003] Currently, most concealed junction boxes are fixed using cement mortar. After installation, these boxes are prone to loosening and damage due to frequent plugging and unplugging, requiring replacement. Removing and installing concealed junction boxes is cumbersome, often requiring damage to the wall surface. Therefore, a concealed junction box for building electrical systems is needed. This type of box can be fixed using a fixed structure, avoiding the need for users to re-fill and fix the boxes with cement mortar when replacing them, thus improving the efficiency of concealed junction box replacement. Summary of the Invention

[0004] The purpose of this utility model is to provide a concealed junction box for building electrical systems, which can be fixed by a fixing structure, avoiding the need for users to re-fill and fix the concealed junction box with cement mortar when replacing it, thereby improving the replacement efficiency of the concealed junction box and solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A concealed junction box for building electrical systems includes a pre-assembled box fitted onto the surface of the junction box. Grooves are provided on both sides of the inner cavity of the pre-assembled box. A locking block is fixedly connected to the front and back of the inner cavity of each groove. Fixing frames are provided through both sides of the inner cavity of the junction box. A sliding groove is provided on one side of each of the two fixing frames opposite to each other. Two symmetrical sliders are slidably connected to the inner cavity of the sliding groove. A locking block is fixedly connected to one side of each pair of sliders opposite to each other. A sliding rod is fixedly connected to the inner cavity of the sliding groove. The sliding rod passes through the slider and is slidably connected to it. A spring is fitted onto the surface of the sliding rod. Two symmetrical openings are provided on the opposite sides of each of the two fixing frames. A lever is fixedly connected to the side of the slider away from the locking block. The lever passes through the opening to the outside of the sliding groove.

[0006] Preferably, the front and back of the junction box are provided with positioning grooves, and the front and back of the pre-assembled box cavity are fixedly connected with positioning strips, and the positioning grooves are adapted to the positioning strips.

[0007] Preferably, two symmetrical connecting strips are fixedly connected to both sides of the pre-packaged box, and the connecting strips are rectangular strips.

[0008] Preferably, both the junction box and the pre-assembly box have multiple detachable baffles on their surfaces, and the corners of both the junction box and the pre-assembly box are rounded.

[0009] Preferably, the second locking block is triangular, and the two ends of the spring are fixedly connected to two symmetrical sliders respectively.

[0010] Preferably, the opening is a rectangular groove, and anti-slip textures are provided on the opposite sides of the two levers.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model fixes the pre-installed box in the groove of the wall, then places the junction box in the inner cavity of the pre-installed box, presses the junction box, and causes the second locking block to move in opposite directions under the pressure of the first locking block, causing the spring to contract. When the junction box is fully inserted into the inner cavity of the pre-installed box, the spring will expand, so that the second locking block reaches below the first locking block. This achieves the purpose of fixing the hidden junction box through the fixing structure, avoiding the need for users to re-fill the gap with cement mortar when replacing the hidden junction box, thus improving the efficiency of replacing the hidden junction box.

[0013] 2. By using the positioning groove and positioning strip in combination, this utility model can distinguish the left and right and front and back positions of the wire box when placing it in the inner cavity of the pre-assembled box by aligning the positioning groove and positioning strip. This avoids the user having difficulty distinguishing the left and right and front and back positions of the wire box and improves the efficiency of wire box installation.

[0023] Figures 1-4 show a concealed electrical junction box for buildings according to an embodiment of the present invention. It includes a pre-installed box 2 fitted onto the surface of a junction box 1. Grooves 3 are formed on both sides of the inner cavity of the pre-installed box 2. Locking blocks 4 are fixedly connected to the front and back of the inner cavity of the grooves 3. Fixing brackets 5 are provided through both sides of the inner cavity of the junction box 1. Sliding grooves 6 are formed on opposite sides of the two fixing brackets 5. Two symmetrical sliders 7 are slidably connected to the inner cavity of the sliding grooves 6. Locking blocks 8 are fixedly connected to opposite sides of the two pairs of sliders 7.

[0024] Working Principle: When using this utility model, the user places the pre-installed box 2 in the groove of the wall, fills and fixes the pre-installed box 2 with cement mortar, then places the junction box 1 in the inner cavity of the pre-installed box 2, and presses the junction box 1, causing the first locking block 4 to squeeze the second locking block 8. This causes the two symmetrical second locking blocks 8 to move in opposite directions under pressure. At this time, the second locking block 8 will drive the two symmetrical sliders 7 to squeeze the spring 10, causing the spring 10 to contract under pressure. When the junction box 1 is fully inserted into the inner cavity of the pre-installed box 2, the spring 10 will expand, causing the two symmetrical sliders 7 to move away from each other. This causes the two symmetrical sliders 7 to drive the two symmetrical second locking blocks 8 to move away from each other, so that the second locking block 8 will reach the bottom of the first locking block 4. At this time, the first locking block 4 will limit the second locking block 8, thus limiting the junction box 1 in the inner cavity of the pre-installed box 2. This avoids the need for the user to re-fill and fix the groove with cement mortar when replacing the concealed junction box, thus improving the efficiency of replacing the concealed junction box.

[0025] In summary, this concealed electrical junction box for buildings, by fixing the pre-installed box 2 in the wall groove, and then placing the junction box 1 inside the pre-installed box 2, pressing the junction box 1 causes the locking block 2 8 to move in opposite directions under the pressure of the locking block 1 4, causing the spring 10 to contract. When the junction box 1 is fully inside the pre-installed box 2, the spring 10 will expand, allowing the locking block 2 8 to reach below the locking block 1 4. This achieves the purpose of fixing the concealed junction box through a fixing structure, avoiding the need for users to re-fill and fix it with cement mortar when replacing the concealed junction box, thus improving the efficiency of concealed junction box replacement.
