Description
Technical Field
[0001] This utility model relates to the field of building electrical installation technology, specifically to an electrical box for pre-embedding during wall construction or concrete pouring. Background Technology
[0002] In building electrical construction, embedded junction boxes, also known as concealed boxes, are core components used to accommodate wire joints, install switches, and socket panels. Their performance directly affects construction efficiency and later use stability. Existing embedded junction boxes have the following core pain points: Traditional junction boxes are rigid, one-piece structures with a fixed depth of 50mm or 70mm. However, modern building walls vary greatly in thickness, such as lightweight partition walls being only 80-100mm thick and floors with underfloor heating being 120-150mm thick. This results in junction boxes either protruding from the wall surface and unable to install panels, or being recessed too deeply and difficult to wire. Traditional junction boxes only have one inlet hole on the side or bottom, requiring all conduits to be squeezed into the same interface. The width direction can accommodate a maximum of two Φ20mm conduits, making it difficult to thread wires when the conduit diameter increases or the wiring becomes complex. The junction box interface is only compatible with a single conduit specification (such as Φ20mm). When connecting Φ25mm conduits or corrugated pipes, additional adapters are required, increasing the inventory of accessories and construction complexity.
[0003] Therefore, there is an urgent need for a pre-embedded junction box that is adjustable in depth, has a large capacity for incoming and outgoing lines, and has strong interface compatibility to meet the needs of complex wiring scenarios. Utility Model Content
[0004] This utility model provides an adjustable depth multi-directional universal pre-embedded junction box, specifically a universal pre-embedded junction box that can adapt to wall thickness, support parallel arrangement of multiple lines, and is compatible with mainstream conduit specifications.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An adjustable depth multi-directional universal pre-embedded junction box includes a main body and an adjustment ring. The main body consists of a recessed box, at least one pipe, and a fixing ring. The fixing ring is located at the open end of the recessed box. The adjustment ring is threadedly connected to the fixing ring. By rotating the adjustment ring, the depth of its extension from the fixing ring can be adjusted, thereby compensating for errors in the pre-embedded depth.
[0007] Furthermore, the junction box is also provided with at least one connector, the axis of which is in the same direction as the axis of the tube in the junction box. This design allows multiple wires to be introduced from the same direction, resulting in neater wiring.
[0008] Furthermore, the connector is equipped with a detachable adapter plug for changing the inlet diameter of the connector to adapt to different specifications of conduits, thereby enhancing its versatility.
[0009] Preferably, the junction box, tube, and fixing ring are integral structures formed by one-time injection molding, ensuring structural strength and sealing performance.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] This invention uses a threaded height adjustment ring to easily adjust the effective depth of the junction box, ensuring that the electrical panel can be installed flush with the final wall surface, thus solving the problem of depth error during construction.
[0012] By setting additional connectors and adapter plugs in the same direction, it supports multiple cabling routes in the same direction and conduits of different diameters, meeting the needs of complex construction environments and offering strong versatility.
[0013] The main body of the box is made of one piece, which makes it sturdy and well-sealed, effectively preventing cement slurry from seeping in and improving its service life and reliability. Attached Figure Description
[0014] Figure 1 This is a schematic diagram of the structure of this utility model.
[0015] In the diagram: 1. Junction box; 2. Tube; 3. Fixing ring; 4. Height adjustment ring; 5. Connector; 6. Adapter plug. Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Example 1
[0018] like Figure 1 As shown, an adjustable depth multi-directional universal pre-embedded junction box includes a main body and an adjustment ring 4. The main body consists of a recessed box 1, at least one pipe 2, and a fixing ring 3. The fixing ring 3 is located at the open end of the recessed box 1. The adjustment ring 4 is threadedly connected to the fixing ring 3. By rotating the adjustment ring 4, its depth extending out of the fixing ring 3 can be adjusted, thereby compensating for errors in the pre-embedded depth.
[0019] The junction box 1 is also provided with at least one connector 5, the axis of which is in the same direction as the axis of the conduit 2 of the junction box 1. This design allows multiple wires to be introduced from the same direction, making the wiring more organized.
[0020] The connector 5 is equipped with a detachable adapter plug 6, which is used to change the inlet diameter of the connector 5 to adapt to different specifications of conduits and enhance versatility.
[0021] The junction box 1, tube 2, and fixing ring 3 are integral structures formed by one-time injection molding, ensuring structural strength and sealing.
[0022] Working principle:
[0023] During the pre-embedded construction, the junction box is placed in the template. According to the site conditions, the height adjustment ring 4 is initially rotated to a suitable position. After the pouring is completed, during the wall plastering stage, the worker can finally rotate the height adjustment ring 4 precisely so that its end face is aligned with the future wall surface. When installing the socket, the fixing screws of the socket panel pass through the height adjustment ring 4 and press it firmly onto the wall surface. The installation is firm and flat. When multiple lines need to enter and exit in the same direction, the reserved connector 5 can be used, and the use of the conversion plug 6 can be selected according to the specifications of the conduit.
[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
