Abstract
Description
Technical Field
[0001] This utility model relates to a circular electrical junction box structure, belonging to the field of building construction technology. Background Technology
[0002] During building construction, junction boxes are one of the electrical accessories. Because the wires used in decoration run through conduits, junction boxes are used as transitions at the joints of the wires (such as when the wire is long or the conduit needs to turn a corner). The conduit is connected to the junction box, and the wires inside the conduit are connected in the junction box, which serves to protect and connect the wires. This is what a junction box is.
[0003] Junction boxes are typically fixed inside the wall, connecting the wires inside. Externally, a panel socket is fixedly installed. The panel socket and its pins have a fixed orientation and cannot be rotated, resulting in poor spatial adaptability, easily bent and damaged wires, increased risk of poor contact, insufficient ease of use, and limited aesthetics. In narrow walls or corners, plugs may be impossible to insert due to their fixed orientation, or the wires may be excessively bent after insertion. Incorrect plug orientation may result in incomplete insertion, reducing the contact area between the plug and socket metal contacts, causing overheating, sparking, or unstable power supply. Elderly people or those with mobility issues may need to twist their wrists to insert or remove plugs, leading to a poor experience. Fixed-directional plugs can also cause uncoordinated wiring, affecting the tidiness of the space.
[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
[0005] This utility model addresses the shortcomings of the prior art by providing a circular electrical junction box structure that allows the panel socket to rotate at a certain angle as needed, thereby solving problems such as poor spatial adaptability, easy bending and damage of wires, increased risk of poor contact, insufficient ease of use, and limited aesthetics.
[0006] To solve the above technical problems, the present invention adopts the following technical solution:
[0007] A circular electrical junction box structure includes a cylindrical junction box base with a cylindrical mounting cavity inside the junction box base. The mounting cavity has an open end, and a panel socket rotatably connected to the junction box base is installed inside the open end. The panel socket has a circular structure, and a junction box cover threadedly connected to the junction box base is installed outside the open end. The junction box cover presses the panel socket into the outer end of the junction box base.
[0008] The inner wall of the junction box is provided with a plurality of circumferentially distributed stiffeners. The stiffeners have mounting holes on the side near the opening of the mounting cavity. Compression springs are installed inside the mounting holes and abut against the inner side of the panel socket.
[0009] Furthermore, the bottom periphery of the mounting cavity is provided with multiple circumferentially distributed wire-passing holes, through which the wires enter the mounting cavity.
[0010] Furthermore, the stiffener is a right-angled triangular structure, and the stiffener and the junction box base are integrally formed, with a total of three stiffeners.
[0011] Furthermore, the mounting hole has a circular structure.
[0012] Furthermore, the panel socket has a stepped portion around its perimeter, and the stepped portion has a hemispherical protrusion.
[0013] Furthermore, the junction box cover is composed of an inner screw cylinder and an outer annular cover plate. The screw cylinder and the cover plate are integrally formed, and the diameter of the cover plate is larger than the diameter of the screw cylinder.
[0014] Furthermore, the screw barrel is threadedly connected to the outer end of the junction box seat.
[0015] Furthermore, a circular hole for installing the stepped part of the panel socket is provided at the center of the cover plate, and a groove for engaging with the protrusion is provided on the inner side of the cover plate.
[0016] Furthermore, the panel socket has at least two socket modules inside, which are connected to the wires in the junction box.
[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:
[0018] In this utility model, the outer cover of the junction box presses the circular panel socket into the outer end of the junction box base. The panel socket is connected to the wires inside the junction box base. The panel socket can rotate at a certain angle between the junction box base and the outer cover of the junction box. When rotating, the panel socket is first pressed to disengage the protrusion from the groove, so that the panel socket can be rotated and adjusted at a certain angle. After the angle is adjusted, the protrusion re-engages with the groove under the action of the compression spring.
[0019] The panel socket can be rotated to adjust the plug insertion direction, avoiding problems such as being unable to use it due to insufficient space, easy bending and damage of wires, increased risk of poor contact, insufficient ease of use, and limited aesthetics.

[0028] like Figure 1-5 As shown, this utility model provides a circular electrical junction box structure, including a cylindrical junction box base 1, a cylindrical mounting cavity 11 inside the junction box base 1, an open end in which a panel socket 3 is rotatably connected to the junction box base 1, the panel socket 3 is circular, and a junction box cover 4 threadedly connected to the junction box base 1 is installed outside the open end, the junction box cover 4 presses the panel socket 3 into the outer end of the junction box base 1.
[0029] The bottom periphery of the mounting cavity 11 is provided with a plurality of circumferentially distributed wire holes 12, through which the wires enter the mounting cavity 11.
[0030] The inner wall of the junction box base 1 is provided with a plurality of ribs 13 distributed in a circle. The ribs 13 are right-angled triangular structures and are integrally formed with the junction box base 1. The number of ribs 13 is preferably three.
[0031] The stiffener 13 has a mounting hole 14 on one side near the opening of the mounting cavity 11. The mounting hole 14 is circular and a compression spring 2 is installed inside the mounting hole 14. The compression spring 2 abuts against the inside of the panel socket 3.
[0032] The panel socket 3 has a stepped portion around its periphery, and a hemispherical protrusion 31 is provided on the stepped portion.
[0033] The junction box outer cover 4 is composed of an inner screw cylinder 42 and an outer annular cover plate 41. The screw cylinder 42 and the cover plate 41 are integrally formed, and the diameter of the cover plate 41 is larger than the diameter of the screw cylinder 42.
[0034] The screw 42 is threadedly connected to the outer end of the junction box seat 1.
[0035] The cover plate 41 has a circular hole at its center for mounting the stepped portion of the panel socket 3, and the inner side of the cover plate 41 has a groove 43 that engages with the protrusion 31. Pressing the panel socket 3 can disengage the protrusion 31 from the groove 43, allowing the panel socket 3 to be rotated and adjusted at a certain angle. After the angle is adjusted, the protrusion 31 re-engages with the groove 43 under the action of the compression spring 2.

During rotation, the panel socket 3 is first pressed down, causing the protrusion 31 to disengage from the groove 43, thus allowing the panel socket 3 to rotate and adjust at a certain angle. After the angle is adjusted, the protrusion 31 re-engages with the groove 43 under the action of the compression spring 2.
[0039] The panel socket 3 can be rotated to adjust the plug insertion direction, avoiding problems such as inability to use due to insufficient space, easy bending and damage of wires, increased risk of poor contact, insufficient ease of use, and limited aesthetics.
