Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe fitting connection technology, and more specifically, to a variable angle elbow. Background Technology
[0002] With the accelerating pace of urbanization, the industry's demand for high-quality electrical conduits and accessories is growing daily. In building wiring and automated equipment wiring systems, proper conduit connections and minimizing cable damage are crucial for construction efficiency and safety; the practicality of conduit accessories is also a key factor in enhancing market competitiveness. Currently, the conduit elbow designs in the market are relatively traditional, mostly using fixed angle designs. These types of elbows cannot achieve a range of turns, and when encountering complex locations requiring flexible turns during conduit installation, their on-site adjustment capabilities are insufficient, making it impossible to adjust the angle according to the site layout.
[0003] Patent CN115296233A discloses a stable and adjustable bending angle for electrical conduits. It includes a conduit adjustment mechanism comprising a fixed pipe and an adjusting pipe, which are movably connected by a bending assembly. A flexible tube is installed inside both the fixed and adjusting pipes, with both ends fixed to the ends of the fixed and adjusting pipes respectively. Correction mechanisms are located above and below the fixed pipe. As the angle between the adjusting and fixed pipes changes, the electrical wire bends, and the bending is limited by the adjusting and fixed pipes, improving the stability of the bend and facilitating subsequent wiring. However, in this design, if the angle between the fixed and adjusting pipes is too large, the electrical wire is easily squeezed at the bend of the flexible tube, causing damage and creating a safety hazard, thus limiting the maximum bending radius of the electrical wire. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of existing technologies where cables may be squeezed by the bend when the bending angle is too large. This invention provides a variable angle bend that can reduce interference between the cable and the bend, reduce the risk of cable breakage, and increase the maximum bending radius of the cable.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A variable angle elbow is provided, comprising a first body and a second body for passing cables through. The first body and the second body are in communication and rotatably connected. A groove is provided on the side of the outer wall of the first body, and a baffle is slidably installed in the groove. A cable routing cut is provided at the bottom of the groove for passing cables through. The cable routing cut is in communication with the outlet of the first body. The depth of the cable routing cut in the direction of movement of the baffle is less than the length of the baffle in the direction of movement of the baffle.
[0007] This utility model's variable angle elbow assumes the cable passes sequentially through a first body and a second body. The entrance to the first body is the opening of the first body away from the second body, and the exit of the first body is the opening of the first body towards the second body. The entrance to the second body is the opening of the second body towards the first body, and the exit of the second body is the opening of the second body away from the first body. During cable installation, the first and second bodies are rotated relative to each other according to the working environment and usage requirements, adjusting the angle between them so that the plane of rotation is parallel to the cable. After the angle between the first and second bodies meets the requirements, the two cables to be connected are... The conduits are installed at the inlet of the first main body and the outlet of the second main body, respectively. The conduits are fixed by methods such as conduit clamps, so that the cable passes through the first and second main bodies in sequence, realizing the cable turning. After the angle between the first and second main bodies is adjusted, if the cable cannot pass directly through the outlet of the first main body without interfering with the outlet edge or baffle of the first main body before passing through the first and second main bodies, the baffle can be slid in the groove to adjust the position of the baffle. This allows the cable to pass through the cable routing cut while the baffle acts as a shield, preventing the cable from contacting the outlet edge of the first main body and increasing the risk of cable breakage, thereby expanding the maximum bending radius of the cable.
[0008] Furthermore, the wiring cut is U-shaped, and the width of the wiring cut gradually decreases from the exit edge of the first body to the bottom of the wiring cut. The U-shaped wiring cut reduces the amount of material that needs to be cut without changing the maximum bending radius of the cable, thus reducing material waste.
[0009] Furthermore, the inner wall of the second main body is provided with a limiting groove, and the baffle is provided with limiting ribs that can contact the two end side walls of the limiting groove in the direction of movement of the baffle, and the limiting ribs move in the limiting groove. The baffle plate contacts the side wall of the chute near the outlet of the first main body. During the rotation of the second main body relative to the first main body, the limiting groove and the limiting rib move relative to each other. After the second main body rotates a certain angle relative to the first main body, the side wall of the limiting groove contacts the limiting rib. The limiting groove pushes the baffle plate to slide in the chute through the limiting rib, exposing the cable routing cut-out portion, allowing the cable to pass through the cable routing cut-out. When the baffle plate contacts the other side wall of the chute, the relative rotation angle between the first and second main bodies reaches its maximum value. When it is necessary to reduce the rotation angle between the first and second main bodies, the second main body rotates in the opposite direction. When the second main body rotates a certain angle relative to the first main body, the other side wall of the limiting groove contacts the limiting rib, pushing the baffle plate to move in the opposite direction until the relative position of the first and second main bodies returns to the initial state. By utilizing the interaction between the limiting groove and the baffle plate, the position of the baffle plate can be automatically adjusted while adjusting the included angle between the first and second main bodies, so that there is always a gap between the cable and the outlet edge of the first main body or the baffle plate.
[0010] Furthermore, the bottom of the first main body is provided with a circular groove, and the bottom of the inner wall of the second main body is provided with a circular buckle that mates with the circular groove. The axes of the circular groove and the circular buckle coincide, and the circular buckle is engaged in the circular groove and rotatably connected to it. During installation, the circular buckle is inserted into the circular groove. Since the circular buckle and the circular groove are circular structures with coincident axes, the circular buckle can rotate around the center in the circular groove, allowing the second main body to rotate relative to the first main body, thereby adjusting the angle between the second main body and the first main body.
[0011] Furthermore, the first main body includes a first connecting part and a first socket part, and the second main body includes a second connecting part and a second socket part, with the first connecting part and the second connecting part rotatably connected. When installing the cable, the second connecting part is installed on the first connecting part, the angle between the second connecting part and the first connecting part is adjusted, and the conduit is installed on the first socket part and the second socket part, allowing the cable to pass through the first socket part, the first connecting part, the second connecting part, and the second socket part, thus completing the cable installation.
[0012] Furthermore, both the first connecting portion and the second connecting portion are cylindrical structures with openings on their sides. The axes of the first connecting portion and the second connecting portion coincide, and their axes are perpendicular to the axes of the first socket portion and the second socket portion. The cylindrical structure of the first connecting portion and the second connecting portion increases the maximum angle of relative rotation between them, thus expanding the range of cable bending angles.
[0013] Furthermore, the second main body includes an upper cover and a lower cover, the lower cover being detachably installed at the bottom of the upper cover, and the bottom surface of the upper cover fitting against the top surface of the lower cover. Installation is completed by installing the upper cover on top of the lower cover and then rotating both the upper and lower covers to the first main body; if either the upper or lower cover is damaged, it can be replaced individually without replacing the entire second main body.
[0014] Furthermore, the bottom of the upper cover is provided with a first fastening part, and the top of the lower cover is provided with a second fastening part that cooperates with the first fastening part. The first fastening part and the second fastening part are engaged. The upper cover and the lower cover are spliced together by the mutual engagement of the first fastening part and the second fastening part, which is simple in structure and convenient in operation.
[0015] Furthermore, the first fastening part includes a first locking block and a second locking groove, and the second fastening part includes a second locking block that cooperates with the second locking groove and a first locking groove that cooperates with the first locking block. The first locking block is distributed on both sides of the axis of the second main body, and the second locking block is distributed on both sides of the axis of the second main body. The first locking block is disposed on the bottom surface of the upper cover and has a first limiting surface opposite to the bottom surface of the upper cover. The second locking block is disposed on the top surface of the lower cover and has a second limiting surface opposite to the top surface of the lower cover. The first locking block engages with the first locking groove, and the second locking block engages with the second locking groove. When installing the second main body, align the bottom surface of the upper cover with the top surface of the lower cover, insert the first locking block into the first locking groove, and the first limiting surface restricts the upper and lower covers from moving away from each other. Insert the second locking block into the second locking groove, and the second limiting surface restricts the upper and lower covers from moving away from each other. The bottom surface of the upper cover and the top surface of the lower cover are in contact, restricting the upper and lower covers from approaching each other. The second main body has a first locking block and a second locking block on both sides of the axis, which restricts the relative sliding of the upper and lower covers, thereby achieving the fixation between the upper and lower covers. The first limiting surface and the second limiting surface face opposite directions, which makes the connection between the upper and lower covers more stable.
[0016] Furthermore, the upper cover and the lower cover are mirror images of each other. This mirror symmetry makes the forces interacting between the upper and lower covers more uniform and the connection between them more stable.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] The variable angle elbow of this utility model has the following characteristics: 1. After bending the elbow, the position of the baffle can be adjusted so that while the baffle blocks the cable, the cable can pass through the cable routing cut, preventing the cable from contacting the outlet edge of the first body and increasing the risk of cable damage, thereby expanding the maximum bending radius of the cable; 2. Utilizing the interaction between the limiting groove and the baffle, the position of the baffle can be automatically adjusted while adjusting the included angle between the first body and the second body, so that there is always a gap between the cable and the outlet edge of the first body or the baffle; 3. It is composed of the first body, baffle, upper cover and lower cover, which can be quickly disassembled and reassembled. When a component is damaged, it can be replaced without replacing the entire elbow. Attached Figure Description

[0030] Example 1
[0031] like Figures 1 to 5 The first embodiment of the variable angle elbow of this utility model is shown. A variable angle elbow is provided, including a first body 1 and a second body 2 for passing cables through. The first body 1 and the second body 2 are connected and rotatably connected. A groove 121 is provided on the side of the outer wall of the first body 1. A baffle 3 is slidably installed in the groove 121. A cable routing cut 1211 for passing cables through is provided at the bottom of the groove 121. The cable routing cut 1211 is connected to the outlet of the first body 1. The depth of the cable routing cut 1211 in the direction of movement of the baffle 3 is less than the length of the baffle 3 in the direction of movement of the baffle 3.
[0032] This utility model's variable angle elbow assumes the cable passes sequentially through a first body 1 and a second body 2. The entrance of the first body 1 is the opening of the first body 1 away from the second body 2, and the exit of the first body 1 is the opening of the first body 1 towards the second body 2. The entrance of the second body 2 is the opening of the second body 2 towards the first body 1, and the exit of the second body 2 is the opening of the second body 2 away from the first body 1. During cable installation, according to the working environment and usage requirements, the first body 1 and the second body 2 are rotated relative to each other, adjusting the angle between them. The plane of rotation of the first body 1 and the second body 2 is parallel to the cable. After the included angle between the first body 1 and the second body 2 meets the requirements, the two cables to be connected are... The conduits are installed at the inlet of the first body 1 and the outlet of the second body 2, respectively. The conduits are fixed by means of pipe rack clamps, so that the cable passes through the first body 1 and the second body 2 in sequence, realizing the cable turning. After the angle between the first body 1 and the second body 2 is adjusted, before the cable passes through the first body 1 and the second body 2, if the cable cannot pass directly through the outlet of the first body 1 without interfering with the outlet edge of the first body 1 or the baffle 3, the baffle 3 can be slid in the slide groove 121 to adjust the position of the baffle 3. While the baffle 3 plays the role of blocking the cable, the cable can pass through the cable routing cut 1211, preventing the cable from contacting the outlet edge of the first body 1 and increasing the risk of cable damage, thereby expanding the maximum bending radius of the cable.
[0033] like Figure 6 and Figure 7 As shown, the wiring cut 1211 is U-shaped, and the width of the wiring cut 1211 gradually decreases from the exit edge of the first body 1 to the bottom of the wiring cut 1211. The U-shaped wiring cut 1211 can reduce the amount of material that needs to be cut without changing the maximum bending radius of the cable, thus reducing material waste.
[0034] like Figure 1 and Figure 6 As shown, the inner wall of the second main body 2 is provided with a limiting groove 221, and the baffle 3 is provided with limiting ribs 31 that can contact the two end sidewalls of the limiting groove 221 in the direction of movement of the baffle 3. The limiting ribs 31 move in the limiting groove 221. The baffle 3 contacts the end sidewall of the slide 121 near the outlet of the first main body 1. During the rotation of the second main body 2 relative to the first main body 1, the limiting groove 221 and the limiting ribs 31 move relative to each other; Figure 2 As shown, after the second main body 2 rotates relative to the first main body 1 at a certain angle, one end of the sidewall of the limiting groove 221 contacts the limiting rib 31. The limiting groove 221 pushes the baffle 3 to slide in the sliding groove 121 through the limiting rib 31, so that the wiring cut 1211 is partially exposed, allowing the cable to pass through the wiring cut 1211; as Figure 3As shown, when the baffle 3 contacts the side wall of the other end of the slide groove 121, the relative rotation angle between the first body 1 and the second body 2 reaches its maximum value; as Figure 4 As shown, the second body 2 is rotated in the opposite direction. When the second body 2 rotates at a certain angle relative to the first body 1, the other side wall of the limiting groove 221 contacts the limiting rib 31, pushing the baffle 3 to move in the opposite direction until the relative position of the first body 1 and the second body 2 returns to the initial state. By utilizing the interaction between the limiting groove 221 and the baffle 3, the position of the baffle 3 can be automatically adjusted while adjusting the included angle between the first body 1 and the second body 2, so that there is always a gap between the cable and the outlet edge of the first body 1 or the baffle 3.
[0035] In this embodiment, as Figure 1 As shown, when the first body 1 and the second body 2 are parallel, the side wall of the limiting groove 221 near the inlet of the second body 2 contacts the limiting rib 31, and the side wall of the sliding groove 121 near the outlet of the first body 1 contacts the limiting rib 31; Figure 3 As shown, when the rotation angle between the first body 1 and the second body 2 reaches its maximum value, the side wall of the limiting groove 221 away from the inlet of the second body 2 contacts the limiting rib 31, and the side wall of the slide groove 121 away from the outlet of the first body 1 contacts the limiting rib 31. The maximum rotation angle between the first body 1 and the second body 2 is 52°. Figure 2 As shown, when the first body 1 and the second body 2 are parallel, the second body 2 is rotated until the side wall of the limiting groove 221 away from the entrance of the second body 2 begins to contact the limiting rib 31. At this point, the rotation angle between the first body 1 and the second body 2 is 28°. Figure 4 As shown, after the rotation angle between the first body 1 and the second body 2 reaches its maximum value, the second body 2 is rotated in the opposite direction. When the side wall of the limiting groove 221 near the entrance of the second body 2 begins to contact the limiting rib 31, the rotation angle between the first body 1 and the second body 2 is 24°.
[0036] The working principle of the variable angle elbow in this embodiment is as follows: Figure 1 As shown, when installing the cable, with the first body 1 and the second body 2 parallel as the initial state, the first body 1 and the second body 2 can be rotated relative to each other to adjust the angle between them, depending on the working environment and the needs of cable installation. During the rotation of the second body 2 relative to the first body 1, the limiting groove 221 and the limiting rib 31 move relative to each other, as shown in the diagram. Figure 2As shown, when the second body 2 rotates 28° relative to the first body 1, the side wall of the limiting groove 221 away from the entrance of the second body 2 begins to contact the limiting rib 31. The limiting groove 221 pushes the baffle 3 to slide in the slide groove 121 through the limiting rib 31, and part of the cable routing cut 1211 is exposed, allowing the cable to pass through the cable routing cut 1211 without interfering with the exit edge of the first body 1 or the baffle 3; Figure 3 As shown, when the limiting rib 31 of the baffle 3 contacts the side wall of the slide groove 121 away from the outlet of the first body 1, the relative rotation angle between the first body 1 and the second body 2 reaches its maximum value of 52°; Figure 4 As shown, when it is necessary to reduce the rotation angle between the first body 1 and the second body 2, the second body 2 is rotated in the opposite direction. The second body 2 rotates 28° in the opposite direction relative to the first body 1. That is, based on the initial state, when the rotation angle between the second body 2 and the first body 1 is 24°, the other end of the side wall of the limiting groove 221 contacts the limiting rib 31, pushing the baffle 3 to move in the opposite direction. When the limiting rib 31 contacts the side wall of the slide groove 121 near the outlet of the first body 1, the relative position of the first body 1 and the second body 2 is just restored to the initial state. After the angle between the first body 1 and the second body 2 is adjusted, the two conduits that need to be connected are installed on the inlet of the first body 1 and the outlet of the second body 2, respectively. The conduits are fixed by means of pipe rack clamping, so that the cable passes through the first body 1 and the second body 2 in sequence, realizing the cable turning.
[0037] Example 2
[0038] This embodiment is the second embodiment of the variable angle elbow of this utility model. This embodiment is similar to the first embodiment, except that, as Figure 5 and Figure 6 As shown, the bottom of the first main body 1 is provided with a circular slot 122, and the bottom of the inner wall of the second main body 2 is provided with a circular buckle 222 that mates with the circular slot 122. The axes of the circular slot 122 and the circular buckle 222 coincide, and the circular buckle 222 is engaged in the circular slot 122 and rotatably connected to it. During installation, the circular buckle 222 is inserted into the circular slot 122. Since the circular buckle 222 and the circular slot 122 are circular structures with their axes coincident, the circular buckle 222 can rotate around the center in the circular slot 122, allowing the second main body 2 to rotate relative to the first main body 1, thereby adjusting the angle between the second main body 2 and the first main body 1.
[0039] like Figures 5 to 7As shown, the first body 1 includes a first connecting part 12 and a first socket part 11, and the second body 2 includes a second connecting part 22 and a second socket part 21. The first connecting part 12 and the second connecting part 22 are rotatably connected. When installing the cable, the second connecting part 22 is installed on the first connecting part 12, the angle between the second connecting part 22 and the first connecting part 12 is adjusted, and the conduit is installed on the first socket part 11 and the second socket part 21, so that the cable passes through the first socket part 11, the first connecting part 12, the second connecting part 22 and the second socket part 21, thus completing the cable installation. In this embodiment, both the first socket part 11 and the second socket part 21 are sockets.
[0040] Both the first connecting part 12 and the second connecting part 22 are cylindrical structures with openings on their sides. The axes of the first connecting part 12 and the second connecting part 22 coincide, and the axes of the first connecting part 12 and the second connecting part 22 are perpendicular to the axes of the first socket part 11 and the second socket part 21. The cylindrical structure of the first connecting part 12 and the second connecting part 22 can increase the maximum angle of relative rotation between the first connecting part 12 and the second connecting part 22, thereby expanding the range of bending angles of the cable.
[0041] Example 3
[0042] This embodiment is the third embodiment of the variable angle elbow of this utility model. This embodiment is similar to embodiment two, except that, as Figure 5 , Figure 6 and Figure 8 As shown, the second main body 2 includes an upper cover 23 and a lower cover 24. The lower cover 24 is detachably installed at the bottom of the upper cover 23, and the bottom surface of the upper cover 23 is in contact with the top surface of the lower cover 24. The installation is completed by installing the upper cover 23 on top of the lower cover 24 and then rotating the upper cover 23 and the lower cover 24 to the first main body 1 respectively. If the upper cover 23 or the lower cover 24 is damaged, it can be replaced individually without replacing the entire second main body 2.
[0043] like Figure 6 As shown, the bottom of the upper cover 23 is provided with a first fastening part 231, and the top of the lower cover 24 is provided with a second fastening part 241 that cooperates with the first fastening part 231. The first fastening part 231 and the second fastening part 241 are engaged. The upper cover 23 and the lower cover 24 are spliced together by the mutual engagement of the first fastening part 231 and the second fastening part 241. The structure is simple and the operation is convenient.
[0044] The first fastening part 231 includes a first locking block and a second locking groove. The second fastening part 241 includes a second locking block that cooperates with the second locking groove and a first locking groove that cooperates with the first locking block. The first locking blocks are distributed on both sides of the axis of the second main body 2. The second locking blocks are distributed on both sides of the axis of the second main body 2. The first locking block is set on the bottom surface of the upper cover 23. The first locking block is provided with a first limiting surface opposite to the bottom surface of the upper cover 23. The second locking block is set on the top surface of the lower cover 24. The second locking block is provided with a second limiting surface opposite to the top surface of the lower cover 24. The first locking block engages with the first locking groove, and the second locking block engages with the second locking groove. When installing the second main body 2, the bottom surface of the upper cover 23 is aligned with the top surface of the lower cover 24. The first locking block is inserted into the first locking groove, and the first limiting surface restricts the upper cover 23 and the lower cover 24 from moving away from each other. The second locking block is inserted into the second locking groove, and the second limiting surface restricts the upper cover 23 and the lower cover 24 from moving away from each other. The bottom surface of the upper cover 23 is in contact with the top surface of the lower cover 24, restricting the upper cover 23 and the lower cover 24 from moving closer to each other. The second main body 2 has a first locking block and a second locking block on both sides of its axis, which restricts the relative sliding of the upper cover 23 and the lower cover 24, thereby achieving the fixation between the upper cover 23 and the lower cover 24. The first limiting surface and the second limiting surface face opposite directions, which makes the connection between the upper cover 23 and the lower cover 24 more stable. In this embodiment, the first locking block, the first locking groove, the second locking block, and the second locking groove are all provided on the second socket 21.
[0045] The upper cover 23 and the lower cover 24 are mirror images of each other. The mirror images of the upper cover 23 and the lower cover 24 make the forces interacting between the upper cover 23 and the lower cover 24 more uniform and make the connection between the upper cover 23 and the lower cover 24 more stable.
[0046] The working principle of the variable angle elbow in this embodiment is as follows: During installation, align the bottom surface of the upper cover 23 with the top surface of the lower cover 24, insert the first clip into the first slot, insert the second clip into the second slot, and fit the bottom surface of the upper cover 23 with the top surface of the lower cover 24 to complete the installation of the second body 2. Align the second connecting part 22 of the second body 2 with the first connecting part 12 of the first body 1, and insert the circular buckle 222 of the second connecting part 22 of the second body 2 into the circular slot 122 of the first body 1 to complete the installation.
[0047] 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.
[0048] 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.
