Description

Technical Field

[0001] This utility model belongs to the field of special tools for cable protection, and specifically relates to a cable tightening tool for pipe fittings. Background Technology

[0002] In daily operations, especially in the cable duct laying industry, PVC pipes and flexible hoses are often used to protect cables. However, during actual construction, material shortages or special circumstances frequently arise, requiring the splicing and connection of different types of pipe fittings. Existing pipe fitting connections typically use standard fixing clips or straight connectors, but these standard fittings are often incompatible when using different types of pipe fittings, thus requiring manual binding and tightening with wire on-site. While this method can meet temporary needs to some extent, it presents many inconveniences in practice.

[0003] Existing pipe binding methods primarily rely on manual binding, which presents several major problems: First, the wire is prone to slipping during manual binding, leading to insecure binding and affecting the sealing and stability of the pipes. Second, due to the lack of effective fastening tools, the wire often breaks during the tightening process due to excessive localized stress, increasing the difficulty and time cost of the operation. Finally, manual binding is inefficient, time-consuming, and labor-intensive, especially in large-scale construction projects, severely impacting the overall work progress and quality. These problems not only reduce the safety and reliability of the operation but also increase additional labor costs and material waste. Therefore, developing a specialized tool that can effectively solve these problems is particularly urgent. Utility Model Content

[0004] The purpose of this utility model is to provide a pipe tightening tool to overcome the deficiency of the existing technology in the lack of a special tool for pipe binding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A pipe tightening tool, comprising: The positioning sleeve has a fastening rod inside and a fixing head at the bottom, with a first opening on the fixing head for securing the iron wire. The handle is connected to the top of the fastening rod via a fastener; A fixing plate is set inside the positioning sleeve and fixedly connected to the bottom end of the fastening rod. The positioning sleeve has a limiting groove on its wall for vertically limiting the fixing plate. Both ends of the fixing plate extend out of the positioning sleeve, and each extended end has a second opening for fixing the end of the wire.

[0006] Two limiting grooves are symmetrically arranged on both sides of the positioning sleeve, and the two ends of the fixing plate are respectively accommodated in the corresponding limiting grooves.

[0007] The fixing head is welded to the bottom of the positioning sleeve, and the first opening is a U-shaped groove structure.

[0008] The fastener is a nut, and the handle is welded to the nut. The length of the handle is 14-20cm.

[0009] The fixing plate includes a plate body and fixing parts at both ends of the plate body. The second opening is provided on the fixing parts, and the length of the plate body is 5-8cm.

[0010] The height of the positioning sleeve is 7-10cm, and the height of the fixing head is 5-8cm.

[0011] The ratio of the height of the fixing head to the height of the positioning sleeve is 1:1.2-1.6.

[0012] The length of the fixing plate is greater than the outer diameter of the positioning sleeve.

[0013] The second opening is either a circular through hole or a U-shaped opening.

[0014] The positioning sleeve is a round or square tube structure, and the distance from the uppermost end of the handle to the top of the positioning sleeve is 0.6-1.2cm.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: This utility model provides a pipe tensioning tool that, through a structured design of a positioning sleeve, a fastening rod, a fixing head, a handle, and a fixing plate, constructs a specialized tool for pipe binding, effectively overcoming the deficiency of existing technologies that lack such specialized tools. The positioning sleeve has a fixing head at its bottom, with a first opening on the fixing head that can lock and limit the wire. Simultaneously, both ends of the fixing plate extend beyond the positioning sleeve, with a second opening at its extended end that can fix the end of the wire. The combination of these two components prevents the wire from slipping during binding, solving the problem of loosening and affecting sealing and stability in existing manual binding methods due to ineffective wire fixation. The handle is connected to the top of the fastening rod via a fixing component. The bottom of the fastening rod is fixedly connected to the fixing plate inside the positioning sleeve. The limiting groove opened in the wall of the positioning sleeve can vertically limit the fixing plate. When the operator applies force through the handle, the fastening rod and the fixing plate can move vertically along the limiting groove to achieve uniform fastening of the wire. This avoids the problem of wire breakage caused by excessive local force during manual fastening. At the same time, it replaces the inefficient operation of manual binding, improves work efficiency, and effectively makes up for the shortcomings of existing technology in the lack of special tools for pipeline binding.

[0018] In cable duct laying operations, PVC pipes and flexible hoses are often used to protect cables. However, due to material shortages or special circumstances, different types of pipe fittings need to be spliced ​​together during actual construction. Existing standard fixing clips and straight connectors are difficult to adapt, so manual binding with wire is the only option on site.

[0019] However, traditional methods have many problems: the wire is easy to slip, resulting in loose binding and affecting sealing and stability; the wire is prone to breakage due to excessive local stress during tightening, increasing the difficulty and time cost of the operation; and it is inefficient, time-consuming and labor-intensive, which seriously affects the progress and quality of large-scale construction, as well as reducing safety, increasing labor costs and material waste. Therefore, it is urgent to develop special tools.

[0020] Based on the above background, this utility model proposes a pipe fitting tightening tool. Through the coordinated arrangement of a positioning sleeve, a fastening rod, a fixing head, a handle, and a fixing plate, a specialized tool for pipe fitting binding is formed, overcoming the shortcomings of existing technologies that lack specialized tools. The first opening of the fixing head can hold the wire, and the second opening at the protruding end of the fixing plate can fix the end of the wire. The two work together to restrict wire slippage, solving the problem of easy loosening during manual binding. The handle is connected to the top of the fastening rod, and the bottom of the fastening rod is fixed to the fixing plate. The limiting groove on the wall of the positioning sleeve vertically limits the fixing plate. Operating the handle can drive the fastening rod and the fixing plate to move vertically along the limiting groove, achieving uniform tightening of the wire and avoiding localized stress that could cause wire breakage. Simultaneously, it replaces manual operation, improving efficiency and effectively compensating for the lack of specialized tools.

[0025] Reference Figure 1 The image shows a specific embodiment of the pipe tightening tool provided by this utility model, comprising: The positioning sleeve 1 has a fastening rod 4 inside and a fixing head 2 at the bottom. The fixing head 2 has a first opening 5 for locking the iron wire. The handle 3 is connected to the top of the fastening rod 4 via a fixing member; The fixing plate 7 is set inside the positioning sleeve 1 and fixedly connected to the bottom end of the fastening rod 4. The positioning sleeve 1 has a limiting groove on its wall for vertically limiting the fixing plate 7. Both ends of the fixing plate 7 extend out of the positioning sleeve 1, and each extended end has a second opening 6 for fixing the end of the wire.

[0026] In this specific embodiment, the positioning sleeve 1 provides a basic installation and support frame for the entire tool. It houses the fastening rod 4, allowing the fastening rod 4 to move in a preset direction within the space defined by the positioning sleeve 1, thus preventing the fastening rod 4 from shifting during operation. The bottom of the positioning sleeve 1 is provided with a fixing head 2, on which a first opening 5 for securing the wire is formed. This first opening 5 can radially limit the wire, preventing the wire from sliding laterally during the binding process, thereby solving the problem of the wire easily sliding and causing the binding to be insecure when manually binding in the prior art.

[0027] The handle 3 is connected to the top of the fastening rod 4 through a fastener. This structural design makes it easy for the operator to apply external force. The operating force can be stably transmitted to the fastening rod 4 through the handle 3, avoiding uneven force application caused by the operator directly contacting the fastening rod 4. At the same time, it reduces the difficulty of operation and solves the problem that manual fastening is laborious and the binding effect is easily affected by improper force application in the existing technology.

[0028] The fixing plate 7 is set inside the positioning sleeve 1 and fixedly connected to the bottom end of the fastening rod 4, so that the movement of the fastening rod 4 can synchronously drive the fixing plate 7 to move. The positioning sleeve 1 has a limiting groove on its wall for vertically limiting the fixing plate 7. The limiting groove can limit the fixing plate 7 to move only in the vertical direction, preventing the fixing plate 7 from shifting laterally during the movement and ensuring the stability of the force direction during the wire fastening process. The two ends of the fixing plate 7 extend out of the positioning sleeve 1, and each extended end has a second opening 6 for fixing the end of the wire. The extended design can be adapted to the fixing position of the end of the wire. The second opening 6 can effectively fix the end of the wire. It cooperates with the first opening 5 on the fixing head 2 to achieve multi-point fixing of the two ends and the middle position of the wire, further enhancing the stability of the wire fixing and preventing the wire from breaking due to excessive local force during the fastening process. At the same time, the mechanical structure replaces manual binding, improving binding efficiency and solving the problems of low efficiency and easy breakage of wire in the existing technology.

[0029] In another specific embodiment of this utility model, there are two limiting grooves symmetrically arranged on both sides of the positioning sleeve 1. The two ends of the fixing plate 7 are respectively accommodated in the corresponding limiting grooves. The symmetrically arranged limiting grooves can make the fixing plate 7 more evenly stressed during vertical movement, avoid the fixing plate 7 tilting due to unilateral stress, and further ensure the stress stability when the wire is tightened. At the same time, the structure at both ends can effectively limit the lateral displacement of the fixing plate 7, ensuring that it only moves along the preset vertical trajectory.

[0030] The fixing head 2 is welded to the bottom of the positioning sleeve 1. This welding connection enhances the connection strength between the fixing head 2 and the positioning sleeve 1, preventing the fixing head 2 from falling off or loosening during tool use and ensuring the overall reliability of the tool structure. The first opening 5 is a U-shaped slot structure. The U-shaped slot opening design facilitates the quick insertion of the wire, while the side wall of the slot effectively limits the wire, preventing it from coming out of the first opening 5 during binding, thus solving the problem of easy wire displacement during manual binding in the prior art. The height of the fixing head 2 is 5-8cm, and in this specific embodiment, a height of 6.3cm is used. This height setting allows the fixing head 2 to adapt to pipe fittings of different diameters, ensuring that the wire fits snugly against the outer wall of the pipe fitting after being inserted, improving the binding seal.

[0031] The fixing component is a nut, and the handle 3 is welded to the nut. Welding ensures the firmness of the connection between the handle 3 and the nut, prevents relative rotation between the handle 3 and the nut during operation, and ensures stable transmission of operating force. The length of the handle 3 is 14-20cm, and 14cm is used in this specific embodiment. This length is ergonomic, making it easy for the operator to grip and apply rotational force, reducing operator fatigue, and avoiding the problem of limited operating space due to an excessively long handle 3 or insufficient force due to an excessively short handle 3. The distance from the top of the handle 3 to the top of the positioning sleeve 1 is 0.6-1.2cm, and 0.9cm is used in this specific embodiment. This distance avoids interference between the handle 3 and the top of the positioning sleeve 1 during operation, ensures the flexibility of the handle 3 rotation, and ensures that the fastening rod 4 has sufficient vertical movement space.

[0032] The fixing plate 7 includes a plate body and fixing parts at both ends of the plate body. The second opening 6 is disposed on the fixing part. The fixing part allows the second opening 6 to maintain a reasonable distance from the positioning sleeve 1, facilitating the installation and fixing of the wire end. At the same time, the plate body structure can ensure the overall rigidity of the fixing plate 7 and prevent bending deformation under stress. The length of the plate body is 5-8cm, and 6cm is used in this specific embodiment. The length of the fixing plate 7 is greater than the outer diameter of the positioning sleeve 1. This length setting ensures that both ends of the fixing plate 7 can smoothly extend out of the positioning sleeve 1, so that the second opening 6 can be positioned to facilitate fixing the wire end. At the same time, the design of being greater than the outer diameter of the positioning sleeve 1 can prevent the wire from interfering with the positioning sleeve 1 during fixing, ensuring the stability of the wire fixing. The second opening 6 is a circular through hole or a U-shaped opening. The two opening forms can be flexibly selected according to the diameter of the wire. The circular through hole can form a tighter wrapping and limiting of the wire, while the U-shaped opening facilitates quick loading and unloading of the wire, improving the convenience of operation.

[0033] The positioning sleeve 1 has a round or square tube structure. The two structural forms can be selected according to the actual use scenario and processing requirements. The round tube structure facilitates the smooth sliding of the fastening rod 4 inside, while the square tube structure can better restrict the circumferential rotation of the fastening rod 4 and improve the overall structural stability of the tool. The height of the positioning sleeve 1 is 7-10cm. In this specific embodiment, a height of 8cm is used. This height setting allows the positioning sleeve 1 to accommodate a fastening rod 4 of sufficient length, ensuring that the fastening rod 4 has sufficient vertical movement stroke to meet the wire fastening requirements of different tightness.

[0034] A fastening rod 4 is installed inside the positioning sleeve 1. One end of the fastening rod 4 is connected to the handle 3 via a nut, and the other end is connected to the fixing plate 7. This connection structure forms a transmission chain from the handle 3 to the nut, then to the fastening rod 4, and finally to the fixing plate 7. This ensures that when the operator turns the handle 3, the fastening rod 4 can move synchronously through the nut, thereby driving the fixing plate 7 to move. In use, the middle of the wire is inserted into the first opening 5 and placed below the pipe to be fixed. The wire is wound around the pipe several times to form a wire loop. The two ends of the wire are then fixed in the second opening 6. Then, the handle 3 is turned, and the nut lifts the fastening rod 4 upward. Since the two ends of the fixing plate 7 are accommodated in the limiting groove, the limiting groove forms a circumferential limit on the fixing plate 7, so that the fastening rod 4 will not rotate circumferentially with the handle 3, but can only move vertically upward, thereby driving the fixing plate 7 to move upward. The fixing plate 7 pulls the two ends of the wire upward to tighten, thereby achieving the tightening and binding of the pipe.

[0035] The pipe tensioning tool of this specific embodiment can effectively tighten and secure pipe fittings. By limiting the wire through the first opening 5 and the second opening 6 and ensuring stable transmission through the drive chain, it prevents the wire from breaking due to excessive local stress during the tightening process. It also replaces the traditional manual binding method, effectively improving work efficiency. The tool is simple to operate, requiring no complicated steps, reducing the labor intensity of operators, and achieving safety and labor-saving results. Practical use has proven that the tool is practical and efficient, effectively solving the practical problems of pipe fitting binding in daily production.
