Description

Technical Field

[0001] This utility model belongs to the field of pipeline-related technology, and in particular relates to a composite conduit that is easy to arrange and install. Background Technology

[0002] Conduit is a type of pipe material used to protect electrical wires and cables, widely used in construction, power, and telecommunications industries. It not only prevents wires from external physical damage but also provides a certain degree of fire resistance, moisture protection, and corrosion resistance. Wires and cables typically pass through conduits, which are usually exposed or buried inside walls or other locations. However, conventional conduits still have the following drawbacks in practical use: Traditional PVC and metal pipes are laid separately, requiring multiple installations. Furthermore, strong and weak current wires need to be shielded when they cross, which is very troublesome. There is a lack of an integrated solution that can lay multiple lines at once while ensuring safety and convenient management. In addition, conventional conduits are all single-pipe designs, requiring as many conduits as needed, which requires multiple layings, and the conduits cannot be combined. Secondly, conduits are divided into main conduits and branch conduits. Conventional solutions involve simple splicing, with the joints fixed by wrapping with tape, which is neither safe nor stable, and the installation is cumbersome and inconvenient. Secondly, when the conduit is too long, the difficulty of threading the wires increases significantly. This requires specialized threading tools, which increases costs, time, and difficulty. The conduit does not have the function of assisting in threading. Finally, once the conduit is buried in the wall, it becomes very difficult to accurately locate its position later, as there is a lack of corresponding auxiliary positioning functions. Utility Model Content

[0003] The purpose of this utility model is to provide a composite conduit that is easy to arrange and install. By setting up PVC conduits, partitions, elbows, branch pipes, nylon ropes, ear plates, and magnetic tags, it solves the problems that a single conduit cannot meet all cable wiring needs, that a large number of conduits required for laying multiple lines cannot be combined, that it is inconvenient to connect branch pipes when the conduit is branched, that there is a lack of auxiliary wire pulling function when the conduit is threaded through, and that it is difficult to accurately find the burial position of the conduit after it is buried inside the wall.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a composite conduit that is easy to arrange and install, including three PVC conduits, a branch pipe, and a magnetic tag. The three PVC conduits are arranged in an equilateral triangle when viewed from above, and are fixed to each other in pairs. Threaded joints are fixed through the upper middle part of the periphery of each PVC conduit. The ends of the threaded joints on two of the PVC conduits are threaded with elbows, and the end of the elbow away from the threaded joint is threaded with a branch pipe. Magnetic labels are equidistantly affixed to the outer periphery of all three PVC conduits. The PVC conduit comprises an inner PVC layer, a metal shielding layer, and an outer PVC layer distributed from the inside out. The inner PVC layer, the metal shielding layer, and the outer PVC layer are composite molded together, and the three PVC conduits are integrally molded.

[0005] Furthermore, the outer periphery of the two PVC conduits connected to the branch pipe is also fixed with conduit lugs distributed at equal intervals, while the PVC conduit not connected to the branch pipe is not fitted with conduit lugs.

[0006] Furthermore, two sets of symmetrically distributed limiting strips are fixed on the inner wall of the PVC conduit, and a partition is inserted between the two sets of limiting strips, forming two threading cavities in the PVC conduit on both sides of the partition.

[0007] Furthermore, two rows of symmetrically distributed ear plates are fixed on the inner wall of the PVC conduit, with two ear plates distributed vertically in each row. A nylon rope is sleeved between the two ear plates in the same vertical row, and the nylon ropes connected to the two rows of ear plates are distributed in two threading cavities.

[0008] Furthermore, the partition has three layers, with a metal layer in the middle and PVC layers on both sides of the metal layer.

[0009] Furthermore, a plug is threaded onto the remaining unconnected branch pipe of the threaded joint. The branch pipe has the same construction as the PVC conduit, but its inner diameter is smaller than that of the PVC conduit.

[0010] This utility model has the following beneficial effects: This invention solves the problems of single conduits not being able to meet all cable wiring needs and the inability to combine a large number of conduits required for various line laying by setting up PVC conduits and partitions. The PVC conduit is a composite molding of a PVC inner layer, a metal shielding layer, and a PVC outer layer. It can be used for both high-voltage and low-voltage wiring, as well as for network cables, fiber optic cables, HDMI cables, etc. The whole is formed by three PVC conduits: one can be used as a high-voltage conduit, one as a low-voltage conduit, and the third can be reserved for use in some special line wiring. By reserving one conduit, it is not necessary to add more conduits when the line is expanded. In addition, the PVC conduit is inserted with partitions to divide the inside of the PVC conduit into two chambers, which can be used to divide the line. Alternatively, the partitions can be omitted, so multiple lines can be accessed with only one conduit installation.

[0011] This utility model solves the problem of inconvenient connection of branch pipes when wiring is branched by setting up PVC conduits, elbows, and branch pipes. When branching is required during wiring and conduit installation, the elbow is connected to a threaded connector, the branch line is led out from the elbow, then passed into the branch pipe, and finally screwed into the elbow to complete the connection. The overall structure is simple, easy to operate, and the connection is stable. In addition, the PVC conduit can be directly inserted into the wall or wall using conduit earings without the need for pipe clamps, which facilitates the installation of conduits.

[0012] This invention solves the problem of lack of auxiliary wire-threading function when threading wires through conduits by setting up nylon ropes and ear plates. When it is necessary to thread the wire, simply insert the end of the cable into the PVC conduit, wrap it around the nylon rope, or simply tie it, and then pull the nylon rope out from the other end. The nylon rope rotates on the two ear plates, which can drive the cable through the PVC conduit without the need for external assistance.

[0013] This invention solves the problem of accurately locating the installation position of conduits after they are buried inside walls by setting magnetic tags. When PVC conduits are buried inside walls, construction workers can use a special detector to quickly locate the conduit's direction and position on the wall surface, avoiding accidental damage during drilling.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Please see Figure 1-7 As shown, this utility model is a composite conduit that is easy to arrange and install, including three PVC conduits 1, branch pipes 2, and magnetic tags 3. The three PVC conduits 1 are arranged in an equilateral triangle when viewed from above, and are fixed to each other in pairs. Threaded joints 101 are fixed through the upper middle part of the periphery of each PVC conduit 1. The ends of the threaded joints 101 on two of the PVC conduits 1 are threaded with elbows 102, and the end of the elbow 102 away from the threaded joint 101 is threaded with a branch pipe 2. A plug 1011 is threaded on the remaining threaded joint 101 that is not connected to the branch pipe 2. The structure of the branch pipe 2 is the same as that of the PVC conduit 1, but the inner diameter of the branch pipe 2 is smaller than that of the PVC conduit 1. The three PVC conduits 1 are arranged in a triangle, which appears as a triangle when viewed from above. They are fixed in pairs for greater stability. When a branch line needs to be led out, an elbow 102 (or a tee or other connector) is connected to the threaded connector 101. The branch line is then led out from the elbow 102 and then into the branch pipe 2. Finally, it is screwed into the elbow 102 to complete the connection. The overall structure is simple, easy to operate, and the connection is stable. It is not necessary to connect a plug 1011 to the threaded connector 101 of the branch pipe 2 to seal it and prevent external impurities from entering. Magnetic tags 3 are equidistantly affixed to the outer periphery of the three PVC conduits 1; when they are buried inside the wall, construction workers can use a special detector to quickly locate the direction and position of the conduits on the wall surface to avoid accidental damage when drilling. The PVC conduit 1 includes an inner PVC layer 106, a metal shielding layer 105, and an outer PVC layer 107 distributed from the inside out. The inner PVC layer 106, the metal shielding layer 105, and the outer PVC layer 107 are composite molded together, and the three PVC conduits 1 are integrally molded. Because each PVC conduit 1 has a metal shielding layer 105 inside, it is suitable for wiring of various high-voltage and low-voltage systems. There is no need to distinguish between different types of conduits, and it can be used directly. Moreover, the overall structure is more stable.

[0019] Two PVC conduits 1 connected to branch pipe 2 are also fixed with conduit lugs 103 distributed at equal intervals on their outer periphery. The PVC conduit 1 not connected to branch pipe 2 is not fitted with conduit lugs 103. The conduit lug 103 can be directly driven into the wall with a wall nail without the need for a pipe clamp. The PVC conduit 1, which is reserved for future use, does not need to be installed with the conduit lug 103.

[0020] Two sets of symmetrically distributed limiting strips 104 are fixed on the inner wall of the PVC conduit 1. A partition 5 is inserted between the two sets of limiting strips 104, and two wire-passing cavities are formed in the PVC conduit 1 on both sides of the partition 5. A partition 5 is inserted between the two sets of limiting strips 104. The partition 5 divides the PVC conduit 1 into two threading chambers, which can be used for threading wires separately.

[0021] Two rows of symmetrically distributed ear plates 108 are fixed on the inner wall of the PVC conduit 1, and there are two ear plates 108 in each row, one above the other. A nylon rope 4 is sleeved between the two ear plates 108 in the same vertical row, and the nylon rope 4 connected to the two rows of ear plates 108 is distributed in the two wire-passing cavities. Nylon ropes 4 are inserted into the two ear plates 108 in the same vertical column. When it is necessary to thread the cable, the cable end is inserted into the PVC conduit 1 and simply wrapped around the nylon rope 4 or tied. Then, the nylon rope 4 is pulled out from the other end. The nylon rope 4 rotates on the two ear plates 108, which can drive the cable through the PVC conduit 1 without the need for external force.

[0022] The partition 5 has three layers: the middle layer is a metal layer, and both sides of the metal layer are PVC layers.

[0023] A metal layer is set in the middle of the partition 5 for shielding purposes, so that the two wiring cavities in the same PVC conduit 1 do not interfere with each other.

[0024] The specific working principle of this utility model is as follows: First, three PVC conduits 1 are arranged in a triangular shape, forming a triangle when viewed from above, and are fixed in pairs. Each PVC conduit 1 is provided with a metal shielding layer 105, which makes it suitable for various high-voltage and low-voltage wiring. When wiring, the conduit is inserted into the corresponding PVC conduit 1. A partition 5 can be inserted between the limiting strips 104 in the two sets of PVC conduits 1. The partition 5 divides the PVC conduit 1 into two wiring cavities (a metal layer is provided in the middle of the partition 5 for shielding, so that the cables in the two wiring cavities do not interfere with each other). The cable can be categorized and threaded. Each PVC conduit 1 has a nylon rope 4 installed in its threading cavity. When threading the cable, insert the cable end into the PVC conduit 1 and simply wrap it around the nylon rope 4. Then, pull the nylon rope 4 out from the other end to move the cable from the first end of the PVC conduit 1 to the last end. When a branch line needs to be led out, connect the elbow 102 to the threaded connector 101, then thread the branch line out from the elbow 102, then thread it into the branch pipe 2, and finally screw it into the elbow 102 to complete the connection. Finally, the conduit lug 103 can be directly nailed into the wall with a wall nail.

[0025] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
