Description

Technical Field

[0001] This utility model relates to the field of building electrical pipeline construction technology, specifically a prefabricated low-voltage electrical conduit. Background Technology

[0002] Electrical wires and cables are essential components in building electrical construction. According to national electrical design and construction standards, they must be encased in protective conduits during installation or burial. Before installation, these conduits must be laid, with wires pre-installed inside for threading the wires. The ends of the conduits must be ground to prevent damage to the wires during threading. To ensure smooth threading, junction boxes must be installed at bends and branch points. During construction, the wires are bundled with wire before being pulled into and threaded through the conduits, and then connected to the distribution box and various terminal electrical equipment. All of this work must be completed on-site, involving numerous steps, being time-consuming and labor-intensive, and requiring a high level of professional expertise.

[0003] In recent years, the country has vigorously promoted prefabricated buildings, requiring that as many components and parts as possible in buildings be designed and prefabricated in factories, and that only assembly and connection are required on the construction site. The traditional method of separate pipelines and separate construction of electrical systems is no longer suitable for the requirements of prefabricated buildings. Therefore, a prefabricated low-voltage electrical conduit is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a prefabricated low-voltage electrical conduit to address the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a prefabricated low-voltage electrical conduit, including a first wire protection tube and a second wire protection tube, wherein the first wire protection tube and the second wire protection tube are provided with an assembly mechanism.

[0006] The assembly mechanism includes: a fixed plate and locking blocks. The fixed plate is fixedly sleeved on the outer wall of the first wire protection tube. Four sliding holes are equally spaced around the right side of the fixed plate. A slider is slidably connected to the inner wall of each sliding hole. A limit plate is fixedly connected to the right side of each slider. There are four locking blocks, which are equally spaced around the outer wall of the second wire protection tube and engage with the limit plate. A sliding rod is fixedly connected to the left side of each slider. A rotating disk is rotatably connected to the left side of the fixed plate. Four sliding holes are equally spaced around the left side of the rotating disk. A spring is fixedly connected to the left side of the rotating disk. A pull block is fixedly connected to the left end of the spring. An insertion rod is fixedly connected to the right side of the pull block. The right end of the insertion rod passes through the rotating disk and is inserted into the fixed plate. The insertion rod is slidably connected to the rotating disk.

[0007] Preferably, the limiting plate is arc-shaped, and the inner arc surface of the limiting plate has a slot, in which the card block is engaged.

[0008] Preferably, the second sliding hole is arc-shaped, and the outer wall of the sliding rod is slidably connected to the second sliding hole.

[0009] Preferably, the left side of the fixing plate has a plurality of slots at equal intervals around its circumference, and the right end of the insertion rod is inserted into the corresponding slot.

[0010] Preferably, two positioning rods are fixedly connected to the left side of the second wire protection tube, and two positioning slots are opened on the right side of the first wire protection tube, with the positioning rods inserted into the positioning slots.

[0011] Preferably, a sealing gasket is provided between the first wire protection tube and the second wire protection tube.

[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0013] 1. This prefabricated low-voltage electrical conduit allows the second electrical conduit to be aligned with the first electrical conduit. By rotating the rotating disc, a sliding rod slides within a second sliding hole, causing the sliding rod to move a slider within a first sliding hole. The slider then moves a limiting plate, causing the slot on the limiting plate to engage with the locking block, thus enabling rapid assembly of the first and second electrical conduits. Simultaneously, under the action of a spring, the insertion rod is inserted into the slot, achieving the limiting and fixing of the fixing disc and the rotating disc. This ensures a firm connection between the two electrical conduits. Compared to traditional complex connection methods on construction sites, this significantly saves construction time and labor costs, and improves construction efficiency.

[0014] 2. This type of prefabricated low-voltage electrical conduit allows for precise insertion of the positioning rod into the positioning slot during assembly, quickly determining the relative positions of the two electrical conduits. This avoids misalignment during installation, ensures assembly accuracy, reduces rework caused by positional deviations, and further improves construction efficiency. The sealing gasket effectively prevents dust, moisture, and other impurities from entering the conduit, preventing wire corrosion and extending wire lifespan. It also ensures the normal operation of the low-voltage system, improving the safety and stability of the entire electrical system. Attached Figure Description

[0025] Please see Figure 1-5One embodiment of this utility model is: a prefabricated low-voltage electrical conduit, including a first electrical conduit 1 and a second electrical conduit 2, with electrical wires installed inside the first and second electrical conduits 1 and 2, and an assembly mechanism 3 installed on the first and second electrical conduits 1 and 2; the assembly mechanism 3 includes: a fixing plate 31 and locking blocks 35, the fixing plate 31 being fixedly sleeved on the outer wall of the first electrical conduit 1, and four equally spaced sliding holes 32 being circumferentially formed on the right side of the fixing plate 31, each sliding hole 32 having a slider 33 slidably connected to its inner wall, and each slider 33 having a limit plate 34 fixedly connected to its right side, and four locking blocks 35. Block 35 is circumferentially fixedly connected to the outer wall of the second wire protection pipe 2 at equal intervals. Block 35 is engaged with the limiting plate 34. The limiting plate 34 is arc-shaped, and a slot is opened on the inner arc surface of the limiting plate 34. Block 35 is engaged in the slot, and the slot limits the block 35, thereby fixing the block 35 on the limiting plate 34 and realizing the limiting and fixing of the second wire protection pipe 2. Each slider 33 has a sliding rod 36 fixedly connected to its left side. The left side of the fixed plate 31 is rotatably connected to the rotating plate 37. The left side of the rotating plate 37 has four sliding holes 38 at equal intervals. The sliding holes 38 are arc-shaped. The outer wall of the sliding rod 36 is slidably connected to the sliding holes 38. A spring 39 is fixedly connected to the left side of the turntable 37. A pull block 310 is fixedly connected to the left end of the spring 39. A plug rod 311 is fixedly connected to the right side of the pull block 310. The right end of the plug rod 311 passes through the turntable 37 and is inserted into the fixed plate 31. The plug rod 311 is slidably connected to the turntable 37. Several slots 312 are evenly spaced around the left side of the fixed plate 31. The right end of the plug rod 311 is inserted into the corresponding slot 312, which enhances the connection stability between the fixed plate 31 and the turntable 37, thereby ensuring that the two wire protection pipes are firmly connected and not easily loosened or detached during use. This ensures the reliability of the low-voltage wiring system and protects the second wire. Pipe 2 is aligned with the first wire protection pipe 1. By rotating the rotating disk 37, the sliding rod 36 slides in the second sliding hole 38, causing the sliding rod 36 to drive the slider 33 to slide in the first sliding hole 32. The slider 33 drives the limiting plate 34 to move, so that the slot on the limiting plate 34 engages with the locking block 35, realizing the rapid assembly of the first wire protection pipe 1 and the second wire protection pipe 2. At the same time, under the elastic force of the spring 39, the insertion rod 311 is inserted into the slot 312, realizing the limiting and fixing of the fixing disk 31 and the rotating disk 37, thereby ensuring that the two wire protection pipes are firmly connected. Compared with the traditional complex connection method on the construction site, it greatly saves construction time and labor costs and improves construction efficiency.

[0026] Working principle: Align the second wire protection tube 2 with the first wire protection tube 1. By rotating the rotating disk 37, the sliding rod 36 slides in the second sliding hole 38, causing the sliding rod 36 to drive the slider 33 to slide in the first sliding hole 32. The slider 33 drives the limiting plate 34 to move, so that the slot on the limiting plate 34 engages with the locking block 35, realizing the rapid assembly of the first wire protection tube 1 and the second wire protection tube 2. At the same time, under the elastic force of the spring 39, the insertion rod 311 is inserted into the slot 312, realizing the limiting and fixing of the fixed disk 31 and the rotating disk 37, thereby ensuring that the two wire protection tubes are firmly connected. Conversely, by pulling the pull block 310 to stretch the spring 39, the insertion rod 311 is moved and disengaged from the slot 312, thereby releasing the fixing of the rotating disk 37, allowing the rotating disk 37 to rotate.

[0027] Please see Figure 1-5 Based on the above embodiments, in another embodiment of this utility model, two positioning rods 4 are fixedly connected to the left side of the second wire protection tube 2, and two positioning grooves are opened on the right side of the first wire protection tube 1. The positioning rods 4 are inserted into the positioning grooves. During assembly, the positioning rods 4 are accurately inserted into the positioning grooves, which can quickly determine the relative positions of the two wire protection tubes, avoid misalignment during installation, ensure the accuracy of assembly, reduce rework caused by position deviation, and further improve construction efficiency. A sealing gasket 5 is provided between the first wire protection tube 1 and the second wire protection tube 2. The sealing gasket 5 can effectively prevent dust, moisture and other impurities from entering the inside of the wire protection tube, avoid the wire from being corroded, extend the service life of the wire, and also ensure the normal operation of the weak current system, improving the safety and stability of the entire electrical system.
