Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for electrical pipeline installation, specifically an electrical pipeline fastening device. Background Technology

[0002] Existing electrical conduit fastening devices have several shortcomings in practical applications: Firstly, most devices are designed with fixed lengths, making it difficult to adapt to the different installation needs of single or multiple parallel conduits. Their poor versatility necessitates the customization of specialized devices for different scenarios, increasing usage costs. Furthermore, the stability of the fastening structure is insufficient, often relying on single-point fixing, which is prone to loosening under conduit vibration or its own weight, affecting the fastening effect. Additionally, the devices are not easily disassembled, occupying significant space during storage and hindering transportation and management. Furthermore, misalignment of components during installation can easily lead to fastening failure. Moreover, existing clamps are mostly fixed in model, limiting adaptability and preventing flexible adjustment to accommodate conduits of different diameters. Adding or removing clamps is inconvenient, and the lack of cushioning protection can damage the conduits. These problems significantly restrict the convenience and reliability of electrical conduit installation. Therefore, there is an urgent need to improve the electrical conduit fastening device to solve these issues. Utility Model Content

[0003] The purpose of this invention is to provide an electrical wiring fastening device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an electrical conduit fastening device, comprising a frame, an end cap movably mounted at the end of the frame, an expansion bolt movably mounted on the end cap in the vertical direction, and a sliding groove provided at the center of the frame; the electrical conduit fastening device includes a combination mechanism and a clamping mechanism, the combination mechanism including the frame and the end cap, the two ends of the frame being provided with locking blocks, and the inner side of the end cap being provided with a locking groove for cooperating with the locking blocks; the design of the expansion bolt ensures the stability of the device.

[0005] Preferably, the other end of the frame can be combined with the splicing seat. The two sides of the splicing seat are respectively provided with the slots of the matching blocks. An expansion bolt is movably installed in the center of the splicing seat, so that when there are too many parallel lines in the same direction, the overall length of the device can be extended by adding a frame.

[0006] Preferably, the clamping mechanism includes a frame, the inner side of which is provided with a sliding groove, and the upper edge of which is provided with two sets of baffles. The cross-section of the frame is "convex".

[0007] Preferably, a rectangular limiting block is movably installed in the slide groove. The length of the limiting block is the same as the width of the slide groove, and its width is less than the distance between the baffles. By rotating the limiting block, it is locked under the baffle. At the same time, when locked, the limiting block is prevented from rotating synchronously by the limiting of the baffle.

[0008] Preferably, a clamping bolt is fixedly installed on the upper end of the limiting block, and a nut is movably installed on the clamping bolt through the thread, and the clamping bolt passes through a clamp.

[0009] Preferably, a spring is fixedly installed between the lower end of the clamp and the upper end of the limiting block, and two sets of connecting rods are provided on both sides of the clamp, with a limiting plate at the end of the connecting rod.

[0010] Preferably, the connecting rod is movably installed inside the clamp two. The inner sides of the clamp one and clamp two are provided with semi-circular slots, and rubber pads are provided inside the slots. The clamp two is provided with a recycling groove with the same diameter as the limiting plate. A spring two is fixedly installed between the inner side of the limiting plate and the bottom of the recycling groove. Under normal conditions, the clamp one and clamp two are in complete contact, and the spring two is in its natural state.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This electrical conduit fastening device, through the cooperation of the locking blocks at both ends of the frame with end slot 1 and splicing seat slot 2, allows for flexible adjustment of the number of frames to modify the overall length, adapting to the fixing needs of single or multiple parallel conduits and solving the problem of poor versatility of fixed length devices. The snap-fit ​​connection allows for quick assembly and disassembly without additional tools, greatly simplifying the construction process and improving efficiency. Expansion bolts are provided at both the ends and splicing seats to achieve multi-point fixing, significantly enhancing the stability of the device compared to single-point fixing and effectively preventing loosening due to vibration or the weight of the conduit itself. The disassembled components can be stacked and stored, reducing storage space and facilitating transportation and management. At the same time, the matching shape of the locking blocks and slots has an anti-misalignment function, ensuring that misalignment will not occur during installation, further guaranteeing the fixing effect.

[0012] 2. This electrical conduit fastening device features a clamping mechanism that uses a sliding groove and a rectangular limiting block for locking. The limiting block rotates and locks under the baffle, preventing synchronous rotation during locking and ensuring stability. The clamping bolts and nuts on the limiting block, combined with the elasticity of spring one, allow for flexible adjustment of the clamp's height to accommodate different pipe diameters. Clamp one and clamp two are connected by a connecting rod, a limiting disc, and spring two. The elasticity of spring two ensures a tight fit between the two, while the inner rubber pad cushions pressure and prevents damage to the conduit. Furthermore, the sliding groove design allows for easy addition or removal of clamp components based on the number of conduits, significantly improving the device's versatility and practicality.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] Based on existing technology, most existing devices are designed with a fixed length, making it difficult to adapt to the different installation requirements of single or multiple parallel pipelines. Their poor versatility necessitates the customization of specialized devices for different scenarios, increasing usage costs. Furthermore, the stability of the fixing structure is insufficient, often employing single-point fixing, which is prone to loosening under pipeline vibration or its own weight, affecting the fixing effect. Additionally, the device is not easily disassembled, occupying a large space during storage, making transportation and management inconvenient. Moreover, during installation, component misalignment can easily lead to fixing failure. Therefore, this device incorporates a combination mechanism; please refer to [link / reference]. Figures 1-2 This utility model provides a technical solution: an electrical conduit fastening device, including a frame 1, an end head 2 movably installed at the end of the frame 1, an expansion bolt 3 movably installed in the vertical direction at the end head 2, and a sliding groove 4 provided at the center of the frame 1; the electrical conduit fastening device includes a combination mechanism and a clamping mechanism, the combination mechanism includes a frame 1 and an end head 2, both ends of the frame 1 are provided with locking blocks 202, and the inner side of the end head 2 is provided with a locking groove 201 that matches the locking blocks 202.

[0017] The other end of the frame 1 can be combined with the splicing base 203. The two sides of the splicing base 203 are respectively provided with the slots 204 of the matching block 202. An expansion bolt 3 is movably installed in the center of the splicing base 203.

[0018] Based on the number and length of the pipelines, the frame 1, end caps 2, and splicing base 203 are assembled using a combination mechanism, and expansion bolts 3 are used to fit with the pre-drilled installation holes in the wall to fix the entire device. The number of frames can be quickly increased or decreased according to the number of electrical pipelines to be fixed. For a single pipeline, a single frame is used to work with both end caps; for multiple parallel pipelines, multiple frames are connected in series through splicing bases to extend the overall length, achieving flexible length adaptation. The locking blocks 202 at both ends of the frame 1 can be precisely embedded into the locking groove 201 on the inner side of the end cap 2, or the locking groove 204 on both sides of the splicing base 203. Example

[0019] Based on Embodiment 1, existing clamps are mostly of fixed models, with limited adaptability and inflexible adjustment to accommodate pipelines of different diameters. Adding or removing clamps is inconvenient, and the lack of buffer protection can damage the pipeline. These problems significantly restrict the convenience and reliability of electrical wiring installation. Therefore, this device is equipped with a clamping mechanism to solve the above problems. Please refer to [link to relevant documentation]. Figures 1-5 This utility model provides a technical solution: an electrical pipeline fastening device, the clamping mechanism includes a frame 1, the inner side of the frame 1 is provided with a sliding groove 4, and the upper edge of the frame 1 is provided with two sets of baffles 302.

[0020] A rectangular limiting block 301 is movably installed inside the slide 4. The length of the limiting block 301 is the same as the width of the slide 4, and its width is less than the distance between the baffles 302.

[0021] A clamping bolt 303 is fixedly installed on the upper end of the limit block 301. A nut 304 is movably installed on the clamping bolt 303 through the thread. The clamping bolt 303 passes through the clamp 307.

[0022] A spring 305 is fixedly installed between the lower end of clamp 307 and the upper end of limit block 301. Two sets of connecting rods 310 are provided on both sides of clamp 307, and a limit plate 311 is provided at the end of the connecting rod 310.

[0023] The connecting rod 310 is movably installed inside the clamp 308. The inner sides of the clamp 307 and the clamp 308 are provided with semi-circular slots, and the inner sides of the clamps are provided with rubber pads 306. The clamp 308 is provided with a recycling groove 309 with the same diameter as the limiting plate 311. A spring 312 is fixedly installed between the inner side of the limiting plate 311 and the bottom of the recycling groove 309.

[0024] During installation, after placing the limiting block 301 into the slide groove, rotate it 90°. Its width, smaller than the baffle spacing, allows it to lock under the baffle 302, preventing it from rotating synchronously with the nut 304 during tightening and ensuring stability. The clamping bolt 303 on the limiting block 301 passes through the clamp 307. When the nut 304 is tightened, the spring 305 is compressed, causing the clamp 307 to move downwards; when the nut is loosened, the spring returns to its original position, causing the clamp to move upwards. This elastic adjustment allows for adaptation to pipes of different diameters. The height requirement of the line (loosen the nut when the pipe diameter is large, tighten it when the pipe diameter is small). Under normal conditions, spring 2 312 is in its natural state, and clamp 1 and clamp 2 are closed to form a circular channel (the inner semi-circular groove fits). When the pipeline is inserted, clamp 2 is squeezed and spring 2 is compressed. The elastic force adaptively clamps pipelines of different diameters (the larger the pipe diameter, the greater the compression of spring 2). At the same time, the rubber pad 306 on the inner side of the clamp directly contacts the pipeline, which can buffer the clamping force and prevent the pipeline surface from being scratched.
