Description

Technical Field

[0001] This utility model relates to the technical field of building electrical construction, and more specifically, to a variable angle electrical junction box. Background Technology

[0002] In the production practice of building electrical construction, PVC round junction boxes are key components for connecting and branching pipeline systems. The rationality of their interface design directly affects construction efficiency, material costs, and the long-term operational safety of the lines. Currently, the commonly used traditional PVC junction boxes adopt a fixed socket structure, and the interface angle is strictly limited to a right angle or a small amount of preset fixed curvature, lacking the necessary flexibility.

[0003] This rigid design leads to multiple problems in actual engineering: when pipelines need to change their route due to space constraints such as building beams, columns, or irregularly shaped walls, the fixed socket cannot accommodate the non-standard access angles required by the conduit, forcing construction workers to cut the pipeline on-site or drill secondary holes in the junction box to find a connection path. Such emergency operations not only significantly extend working hours and increase labor costs but also result in wasteful consumption of conduit materials. More seriously, the insulation layer of the conductors is easily damaged during conduit cutting or modification, leading to exposed conductors or decreased insulation performance, creating potential safety hazards such as short circuits, leakage, and even electrical fires. Furthermore, in complex conduit layout scenarios such as power distribution nodes and densely populated equipment areas, fixed interfaces struggle to coordinate the efficient convergence of multi-directional pipelines. Workers are forced to add extra elbows, reducers, or multi-stage transition boxes to achieve pipeline connections, resulting in cumbersome construction procedures, cramped installation space, and reduced system reliability and aesthetics. These structural defects in existing junction boxes have become a significant bottleneck restricting construction quality and safety. Utility Model Content

[0004] The purpose of this invention is to overcome the difficulty of dynamically matching the interface angle of existing PVC junction boxes to the on-site installation requirements, and to provide a variable angle electrical junction box that can effectively improve the flexibility of the junction box interface and improve the installation efficiency of construction personnel.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A variable-angle electrical junction box is provided, including a box body, a first wiring hole communicating with a cavity of the box body is provided on the side wall of the box body, and a movable member, a mounting hole is provided on the side wall of the box body and located on the side opposite to the first wiring hole, the movable member is slidably connected to the box body, and a second wiring hole is provided on the movable member, one end of the mounting hole communicating with the cavity of the box body, and the other end communicating with the second wiring hole.

[0007] In the operation of the above scheme, the junction box has a rotatable movable part installed in the fixed mounting hole on its side wall, and a second wiring hole is opened on the movable part to realize flexible adjustment of the pipe interface angle. When it is necessary to change the connection direction of the pipe entering and leaving the box, the construction personnel can slide the movable part so that the axis of the second wiring hole on the movable part and the first wiring hole on the opposite side of the box wall forms the required angle. Thus, the connection of pipes at different angles can be completed conveniently and accurately without cutting the conduit or additional fittings, which significantly improves the installation efficiency of the construction personnel.

[0008] Furthermore, the box body is cylindrical, and the movable part is attached to the wall of the box body and covers the mounting hole; the movable part adopts a plate-like structure to achieve a rotatable connection with the box body. While the movable part and the mounting hole form a sliding connection, the movable part can also seal the mounting hole to prevent foreign objects from entering the box body through the mounting hole.

[0009] Furthermore, the box body is provided with a limiting part, which is connected to the movable part. The limiting part is used to restrict the movement of the movable part along the radial direction of the box body. The limiting part is used to radially limit the movable part to prevent it from moving radially after being installed into the mounting hole, so that the movable part leaves the inner wall of the box body and avoids gaps that could allow foreign objects to enter.

[0010] Furthermore, the limiting part includes a first protrusion and a baffle. The first protrusion is located at the bottom or top of the mounting hole and is fixedly connected to the inner wall of the box. The baffle is fixedly connected to the side of the first protrusion away from the mounting hole. The bottom or top surface of the movable part is in contact with the first protrusion. The movable part is located between the baffle and the wall of the box. The first protrusion is located at the bottom of the box and plays a role in supporting the movable part to prevent it from moving downward due to gravity. The first protrusion is located at the top of the box and plays a role in blocking to prevent the movable part from moving upward due to external force. The baffle blocks the movable part on the other side of the inner wall of the box, thereby achieving radial limiting of the entire movable part.

[0011] Furthermore, the limiting part also includes a guide groove, and a second protrusion is provided on the surface of the movable part that fits against the side wall of the box. The second protrusion is slidably connected to the guide groove. The second protrusion is a strip-shaped arc protrusion on both sides of the second wiring hole. When the movable part is installed into the mounting hole, the second protrusion is inserted into the guide groove. When the movable part rotates, it can play a guiding role and also limit the up and down movement of the movable part in the direction perpendicular to the bottom surface of the box.

[0012] Furthermore, the movable component is located inside the cavity of the box; at least one second wiring hole is provided on the movable component; the movable component adopts an internal setting, which can avoid damage to the movable component on the one hand, and on the other hand, when the movable component is set outside the box, the sliding of the movable component is easily affected by foreign objects, resulting in poor sliding; two or three second wiring holes can also be provided on the movable component to form a wiring structure of one inlet and two outlets or one inlet and three outlets, thereby improving the practicality of the junction box.

[0013] Furthermore, both the first and second wiring holes are surrounded by annular walls, and the outer surface of the annular walls is provided with reinforcing ribs; since the two wiring holes require wires to be threaded through, the annular walls provide protection for a small section of the cable that passes through and exits, thus achieving the effects of dustproofing and moisture-proofing.

[0014] Furthermore, on the cross-section perpendicular to the axis of the box, the central angle corresponding to the arc length of the mounting hole on the circular wall of the box is between 40° and 50°. After the cable is installed, the interior of the junction box usually needs to be connected to the external structure. In order to avoid interference between the moving parts inside the cavity and the external installation structure, it is usually best to set the rotation range of the moving parts to an angle of 45°.

[0015] Furthermore, it also includes an assembly plate, on which both the first wiring hole and the annular wall are located. The box body is also provided with an assembly opening, and the assembly plate and the assembly opening are detachably connected. The first wiring hole can also be made into a detachable structure. A portion of the side wall is cut out along a direction perpendicular to the bottom surface of the box body. This portion of the side wall is independently called the assembly plate, and the notch cut out of the side wall of the box body is called the assembly opening. The first wiring hole is on the assembly plate. The cut section of the assembly plate is provided with a protrusion, and the cut section of the side wall of the box body is provided with a groove. The protrusion and the groove cooperate to realize the detachable installation of the assembly plate and the assembly opening. This not only improves the modularity of the junction box and allows for replacement when the annular wall of the first wiring opening is damaged, but also facilitates the entry of moving parts into the cavity of the box body through the assembly opening, making it easier to install moving parts.

[0016] Furthermore, the top of the box is open, and several connecting lugs are provided on the inner and outer walls of the top of the box. The junction box needs to be connected to the outside. Threaded holes can be provided on the connecting lugs to realize the installation and positioning of the junction box cover.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. A first wiring hole is provided on the side wall of the junction box, and an installation hole is provided on the opposite side wall of the box. The movable part is rotatably connected to the box through the installation hole. A second wiring hole is provided on the movable part. The construction personnel can rotate the movable part to adapt to the required angle, so that the connection of pipelines at different angles can be completed conveniently and accurately without cutting the conduit or additional fittings, which significantly improves the installation efficiency of the construction personnel.

[0019] 2. Both the first wiring hole and the annular wall are located on the assembly plate. The box body is also provided with an assembly port. The assembly plate and the assembly port can be detachably connected, which not only improves the modularity of the junction box and facilitates replacement when the annular wall is damaged, but also facilitates the installation of moving parts.

[0027] Example 1

[0028] This embodiment is a first embodiment of a variable angle electrical junction box, such as... Figures 1 to 3 As shown, the device includes a housing 100, with a first wiring hole 110 on the side wall of the housing 100 communicating with the cavity of the housing 100. It also includes a movable member 200, with a mounting hole 120 on the side wall of the housing 100 located on the side opposite to the first wiring hole 110. The movable member 200 is slidably connected to the housing 100, and a second wiring hole 210 is provided on the movable member 200. One end of the mounting hole 120 communicates with the cavity of the housing 100, and the other end communicates with the second wiring hole 210.

[0029] Specifically, such as Figure 1 As shown, the box body 100 is a cylinder, and the movable part 200 is attached to the wall of the box body 100 and covers the mounting hole 120. The movable part 200 adopts a plate-like structure to achieve a rotatable connection with the box body 100. While the movable part 200 and the mounting hole 120 form a sliding connection, the movable part 200 can also seal the mounting hole 120 to prevent foreign objects from entering the box body 100 through the mounting hole 120.

[0030] Specifically, the box body 100 is provided with a limiting part 300, which is connected to the movable part 200. The limiting part 300 is used to restrict the movement of the movable part 200 in the radial direction of the box body 100. The limiting part 300 is used to radially limit the movable part 200 to prevent it from moving radially after being installed into the mounting hole 120, so that the movable part 200 leaves the inner wall of the box body 100 and avoids gaps that could allow foreign objects to enter.

[0031] Specifically, the limiting part 300 also includes a first protrusion 310 and a baffle 320. The first protrusion 310 is located at the bottom or top of the mounting hole 120 and is fixedly connected to the inner wall of the box body 100. The baffle 320 is fixedly connected to the side of the first protrusion 310 away from the mounting hole 120. The bottom or top surface of the movable part 200 is in contact with the first protrusion 310. The movable part 200 is located between the baffle 320 and the wall of the box body 100. The first protrusion 310 is located at the bottom of the box body 100 and plays a role in supporting the movable part 200 to prevent the movable part 200 from moving downward due to gravity. The first protrusion 310 is located at the top of the box body 100 and plays a role in blocking to prevent the movable part 200 from moving upward due to external force. The baffle 320 blocks the movable part 200 on the other side of the inner wall of the box body 100, thereby achieving radial limiting of the entire movable part 200.

[0032] The aforementioned limiting part 300 is specifically configured such that the movable part 200 is located inside the cavity of the box body 100. Alternatively, the movable part 200 can also be located outside the cavity of the box body 100 and slidably connected to it. In this case, the limiting part 300 is specifically configured as follows: the first protrusion 310 is fixedly connected to the outer wall of the box body 100 and located at the bottom or top of the mounting hole 120; the first baffle 320 is located on the first protrusion 310; during installation, the two sides of the movable part 200 are respectively in contact with the first protrusion 310 and the outer wall of the box body 100; the bottom surface is in contact with the first protrusion 310 located at the bottom of the mounting hole 120; and the top surface is in contact with the first protrusion 310 located at the top of the mounting hole 120.

[0033] like Figure 2 As shown, if the first protrusion 310 and the baffle 320 are provided at both the bottom and top of the mounting hole 120, it will be inconvenient to install the movable part 200. Therefore, the structure of the first protrusion 310 and the baffle 320 is only provided at the bottom of the mounting hole 120.

[0034] Specifically, the limiting part 300 also includes a guide groove 330, such as Figure 3 As shown, a second protrusion 220 is provided on the surface of the movable part 200 that is in contact with the side wall of the box body 100. The second protrusion 220 is slidably connected to the guide groove 330. The second protrusion 220 is a strip-shaped arc protrusion on both sides of the second wiring hole 210. When the movable part 200 is installed into the mounting hole 120, the second protrusion 220 is inserted into the guide groove 330. When the movable part 200 rotates, it can play a guiding role and also limit the up and down movement of the movable part 200 in the direction perpendicular to the bottom surface of the box body 100.

[0035] The working principle of a variable-angle electrical junction box in this embodiment is as follows:

[0036] During installation, the worker first presses the movable part 200 into the mounting hole 120, allowing it to enter the cavity of the box 100. The position is then adjusted so that the movable part 200 aligns with the first protrusion 310 and the baffle 320 to form radial limits. After installation, the wire is introduced through the first wiring hole 110 and then led out through the second wiring hole 210. When it is necessary to change the direction of the wire exiting the second wiring hole 210, the worker can rotate the movable part 200. Under the action of the guide groove 330 and the second protrusion 220, the axis of the second wiring hole 210 on the movable part 200 and the axis of the first wiring hole 110 on the opposite side of the box 100 wall are adaptively adjusted to the required angle.

[0037] The beneficial effects of this embodiment are: by rotating the movable part 200 to adjust the orientation of the second wiring hole 210, the construction personnel can conveniently and accurately complete the connection of pipelines at different angles without cutting conduits or additional fittings, which significantly improves the installation efficiency of the construction personnel.

[0038] Example 2

[0039] This embodiment is a second embodiment of a variable angle electrical junction box, such as... Figure 1 and 3 As shown, the difference from Embodiment 1 is as follows:

[0040] Specifically, both the first wiring hole 110 and the second wiring hole 210 are surrounded by annular walls 400, and the outer surface of the annular walls 400 is provided with reinforcing ribs. Since the two wiring holes require wires to be threaded through, the annular walls 400 provide protection for a small section of the cable that is threaded through and out, thus preventing dust and moisture and improving the safety of the circuit.

[0041] Specifically, on the cross-section perpendicular to the axis of the box 100, the central angle corresponding to the arc length of the circular wall surface of the mounting hole 120 is between 40° and 50°. After the cables are installed in the junction box, the interior of the box 100 usually needs to form an installation connection with the external structure. In order to avoid interference between the movable part 200 inside the cavity and the external installation structure, it is usually best to set the rotation range of the movable part 200 to an angle of 45°.

[0042] like Figure 1 As shown, when the movable part 200 slides at a certain angle, the annular wall 400 around the second wiring hole 210 will contact the side wall of the mounting hole 120, blocking the movable plate from continuing to rotate. At the beginning of the design, the designer can design the size of the second wiring hole 210 to adjust the rotation angle. The size of the second wiring hole 210 can correspondingly change the circumferential arc length distance between the annular wall 400 and the inner wall of the mounting hole 120, thereby correspondingly changing the rotation angle.

[0043] Specifically, the movable component 200 is located inside the cavity of the box 100; at least one second wiring hole 210 is provided on the movable component 200; the movable component 200 adopts an internal setting, which can avoid damage to the movable component 200 on the one hand, and on the other hand, when the movable component 200 is set outside the box 100, the sliding of the movable component 200 is easily affected by foreign objects, resulting in poor sliding; two or three second wiring holes 210 can also be provided on the movable component 200 to form a wiring structure of one inlet and two outlets or one inlet and three outlets, thereby improving the practicality of the junction box.

[0044] The working principle of a variable-angle electrical junction box in this embodiment is as follows:

[0045] When the movable part 200 rotates clockwise or counterclockwise around the box 100 and reaches its limit position, the annular wall 400 abuts against the inner wall of the mounting hole 120, preventing the movable part 200 from continuing to rotate. During installation, workers can simultaneously introduce various signal lines or wires with different functions through the first wiring hole 110, and then sort and organize the signal lines of different functions or types and thread them into the second wiring holes 210 at different positions on the movable part 200.

[0046] The beneficial effects of this embodiment are: by setting multiple second wiring holes 210 and annular wall 400, the safety of the wiring in the junction box and the practicality of the junction box are effectively improved.

[0047] Example 3

[0048] This embodiment is a third embodiment of a variable-angle electrical junction box, such as... Figure 2 and 4 As shown, the difference from Example 2 is as follows:

[0049] Specifically, it also includes an assembly plate 500, on which the first wiring hole 110 and the annular wall 400 are both located. The box body 100 is also provided with an assembly opening 130. The assembly plate 500 and the assembly opening 130 are detachably connected. The first wiring hole 110 can also be made into a detachable structure. A portion of the side wall is cut out along a direction perpendicular to the bottom surface of the box body 100; this portion of the side wall is independently called the assembly plate 500, and the notch cut out of the side wall of the box body 100 is called the assembly opening. 130, the first wiring hole 110 is on the assembly plate 500. The cut section of the assembly plate 500 is provided with a protrusion, and the cut section of the side wall of the box body 100 is provided with a groove. The protrusion and the groove cooperate to realize the detachable installation of the assembly plate 500 and the assembly hole 130. This not only improves the modularity of the junction box and allows for replacement when the annular wall 400 of the first wiring hole is damaged, but also facilitates the movement of the movable part 200 into the cavity of the box body 100 from the assembly hole 130, making it easier to install the movable part 200.

[0050] like Figure 4 As shown, the bottom surface of the assembly plate 500 away from the connecting ear 140 is a bottom cut section. Several protrusions are provided on this cut section, and several grooves are provided on the bottom section of the assembly port 130. The protrusions are inserted into the grooves to form a detachable connection.

[0051] Specifically, the top of the box 100 is open, and several connecting ears 140 are provided on the inner and outer walls of the top of the box 100. The junction box needs to be connected to the outside. Threaded holes can be provided on the connecting ears 140 to realize the installation and positioning of the junction box cover.

[0052] The working principle of a variable-angle electrical junction box in this embodiment is as follows:

[0053] During installation, the worker first removes the assembly plate 500, then inserts the movable part 200 through the assembly port 130, so that the annular wall 400 protrudes from the mounting hole 120. The movable part 200 is inserted between the baffle 320 and the side wall of the box 100 and fits against the first protrusion 310. Then, along the axis of the cylindrical box 100, the assembly plate 500 is inserted into the assembly port 130 from top to bottom and fixed, and then the wiring operation can be carried out.

[0054] The beneficial effects of this embodiment are: the first wiring port is set on the assembly plate 500, and the assembly plate 500 is detachably connected to the box body 100, which improves the overall modularity of the junction box and facilitates the installation of the movable part 200.

[0055] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
