Description

Technical Field

[0001] This utility model relates to a portable electric cable binding tool, which belongs to the technical field of cable binding tools. Background Technology

[0002] In shipbuilding and industrial production, cable binding after installation is a critical process that directly affects the stability and safety of the lines. Currently, the industry commonly uses manual cable pliers for binding operations. Their structure is an integrated fixed structure of "plier head + manual handle": the plier head only has a simple cable guide groove, and the manual handle drives the plier head to tighten the cable through the lever principle. The entire process relies on manual repeated gripping and force, which is not only labor-intensive, but also takes more than 10 seconds for a single binding, affecting efficiency.

[0003] While some power tools (such as electric screwdrivers and electric wrenches) have been attempted to assist in tying in existing technologies, they suffer from significant structural defects: First, the output end of these tools uses a universal interface, which cannot be stably matched with cable tie pliers, making them prone to loosening and misalignment; second, the bodies are mostly "L-shaped" or "pistol-shaped," making them difficult to maneuver flexibly in confined spaces such as ship cabins and equipment gaps due to their bulky structure; third, they lack portable fixing structures, requiring frequent hand-holding or placement during operation, which increases the risk of slipping from heights and affecting safety; fourth, they cannot precisely adjust the tying torque, easily damaging cables due to excessive force or causing loosening due to insufficient force, and offering poor visibility in low-light cabins and equipment shadow areas, further reducing the quality of work.

[0004] Furthermore, existing hand tools and modified power tools have rudimentary protective structures, making them unsuitable for the humid and dusty environments commonly encountered in marine operations. They also lack a clear system for ensuring continued operation, hindering their ability to meet the demands of large-scale continuous operations. Therefore, there is an urgent need for an electric cable tying tool with optimized structure for adaptability, portability, and protection, and integrated with torque adjustment and lighting functions to address these issues.

[0005] (1) How to design a stable connection structure between the cable tie clamp head and the electric drive device to avoid loosening or misalignment during operation; (2) How to optimize the fuselage structure to adapt it to operation in confined spaces and improve its rotation flexibility; (3) How to add a portable fixing structure to achieve temporary storage and fall prevention of tools; (4) How to ensure stable power output, sufficient range, and adaptability to harsh working environments through internal structural configuration.

[0006] (5) How to achieve precise adjustment of binding torque to adapt to the fastening requirements of cables of different specifications; (6) How to solve the problem of operational visibility in low-light environments and improve operational accuracy; (7) How to optimize the switch operation logic to achieve convenient switching between forward, reverse and stop, and reduce misoperation. Utility Model Content

[0007] To address the problems existing in the prior art, this utility model provides a portable and efficient binding power tool through structural optimization, which is particularly suitable for fixing metal in confined spaces. It integrates torque adjustment, directional lighting, and anti-misoperation functions to further improve work adaptability and safety.

[0008] The technical solution adopted by this utility model is: a portable electric cable binding tool, which includes a cable tie clamp body, a power mechanism, a tightening mechanism and a cutting mechanism; The front end of the cable tie clamp body is provided with a fish-mouth shaped cable tie guide. The power mechanism includes a motor unit, a transmission unit, and an output unit installed inside the housing. The output unit is connected to the output shaft of the reducer. A first bevel gear is installed at the end of the output shaft of the reducer. The first bevel gear meshes with a second bevel gear, which drives the tightening gear shaft to rotate. In the tightening mechanism, the tightening gear is fixed on the tightening gear shaft, and a tightening component is provided on the outer periphery of the tightening gear. A cable tie slot is provided on the tightening component. In the cutting mechanism, the cutting platform is fixed on the main body of the cable tie clamp, and the cutter is fixed on the operating rod through the cutting rod. Lifting the operating rod causes the cutter to rotate, which acts on the cutting platform to cut the cable ties.

[0009] Furthermore, the depth of the cable tie guide and cable tie slot is 3-8 times the width of the cable tie.

[0010] Furthermore, a light is provided at the front end of the fuselage housing, and the light is turned on or off by a light switch.

[0011] Furthermore, a magnetic block for adsorption and fixation is provided at the tail of the housing.

[0012] Furthermore, a wrist strap is provided on the housing.

[0013] Furthermore, when the cable tie is tightened, the operating lever is lowered; there is a gap between the cutter and the cutter platform for the cable tie to pass through.

[0014] Furthermore, the tool also features a torque adjustment knob for adjusting torque.

[0015] Furthermore, the cable tie guide opening is provided with anti-slip teeth.

[0016] Compared with existing technologies, this utility model has the following advantages: Based on a cable tie clamp body, the tool features a fish-mouth shaped cable tie guide at the front end, combined with internal anti-slip teeth. The guide and slot design, with a depth 3-8 times the width of the cable tie, accurately guides the cable tie feed and prevents it from shifting or falling off during the binding process. It is particularly suitable for metal fixing operations in confined spaces, effectively solving the problem of inconvenient operation of traditional tools in narrow areas. The power mechanism achieves electric drive for cable tie tightening, and with an adjustable torque adjustment knob, the tightening force can be precisely controlled according to different binding needs, avoiding over-tightening that could damage cables or loosening the binding, thus improving operational adaptability. The cutting mechanism controls the interaction between the cutter and the cutting platform via an operating lever. Lowering the lever ensures the cable ties pass through smoothly when tightening, while raising the lever enables rapid cutting of the cable ties, making operation convenient and efficient. Meanwhile, the integrated lighting at the front of the machine housing (controlled by an independent lighting switch) provides directional illumination in dim environments, and the magnetic block at the rear facilitates temporary attachment and fixation of the tool. The wrist strap design enhances portability and safety, effectively preventing accidental drops. The overall structure is compact and feature-rich, significantly improving the efficiency and safety of cable binding operations in confined spaces and meeting the needs of diverse work scenarios.

[0028] This patent integrates existing electric drive devices (such as brushless motors) with cable tie pliers heads. By optimizing the overall tool structure, connection method, portable components, protective design, and functional control components, a practical electric cable binding tool is formed. The specific solution is as follows: A portable electric cable binding tool includes a cable tie clamp body 1, a power mechanism, a tightening mechanism, and a cutting mechanism; the front end of the cable tie clamp body 1 is provided with a fish mouth-shaped cable tie guide 2; the cable tie guide 2 is provided with anti-slip teeth.

[0029] The power mechanism includes a motor unit 12, a transmission unit 11 and an output unit 10 installed in the housing 5. The output unit 10 is connected to the output shaft 14 of the reducer. The end of the output shaft 14 of the reducer is provided with a first bevel gear 17. The first bevel gear 17 meshes with a second bevel gear 18, which drives the tightening gear shaft 23 to rotate. In the tightening mechanism, the tightening gear 19 is fixed on the tightening gear shaft 23, and the tightening member 6 is provided on the outer periphery of the tightening gear 19. The cable tie slot 5 is provided on the tightening member 6. The depth of the cable tie guide 2 and the cable tie slot 5 is 3-8 times the width of the cable tie.

[0030] In the cutting mechanism, the cutting platform 4 is fixed to the cable tie clamp body 1, and the cutter 3 is fixed to the operating lever 7 via the cutting rod 24. Lifting the operating lever 7 causes the cutter 3 to rotate, which in turn acts on the cutting platform 4 to cut the cable tie. When the cable tie is tightened, the operating lever 7 is lowered; there is a gap between the cutter 3 and the cutting platform 4 for the cable tie to pass through.

[0031] A light 20 is provided at the front end of the housing 15, and the light 20 is controlled to be turned on or off by a light switch 22. A magnetic block 9 for magnetic attachment is provided at the rear end of the housing 15. A wrist strap 13 is provided on the housing 15. The tool is also provided with a torque adjustment knob 21 for adjusting torque.

[0032] The electric cable tying tool is composed of various parts connected by mechanical links. The components work together to achieve efficient cable tying. The following is a detailed description of each component: (1) Clamping head assembly The clamp head assembly integrates a cable tie guide 2 with anti-slip teeth on the inner side to enhance the guiding stability of the cable tie and prevent slippage; a tightening gear 19 (connected to the electric drive assembly to provide power transmission for tightening the cable tie) and a cutter 3, controlled by an operating lever 7 to achieve the cable tie cutting action. After assembly, the tightening gear 19 and the tightening component 6 are secondary tightened with bolts to form a high-strength, vibration-resistant connection structure, ensuring a stable connection between the clamp head and the drive assembly during the binding operation and preventing loosening from affecting the binding accuracy.

[0033] (2) Electric drive component package The electric drive assembly consists of a motor unit 12 (300W brushless motor) and a transmission unit 11 (including a planetary gear reducer with a reduction ratio of 1:5). The brushless motor features high efficiency, low noise, and long lifespan. The planetary gear reducer is coaxially fixed to the motor via a flange, ensuring coaxiality of power transmission. The reducer output shaft 14 drives the first bevel gear 17 to rotate, and the first bevel gear 17 meshes with the second bevel gear 18. The second bevel gear 18 drives the tightening gear shaft 23 to rotate, which in turn drives the tightening gear 19 and the external tightening component 6 to rotate, achieving the rotational tightening of the cable tie. A stable power transmission path is established. The motor output power is reduced and amplified before driving the tightening gear to rotate, achieving automatic and precise tightening of the cable tie and meeting the tightening requirements of the cable tie under different working conditions. At the same time, the transmission device has a built-in torque sensing module that is linked with the torque adjustment component of the machine body to provide real-time feedback and control of the output torque.

[0034] (3) Fuselage The casing features a streamlined, linear design (280mm in length, 55mm in diameter), primarily constructed from ABS engineering plastic (4mm thick), combining lightweight design with structural strength. The inner side of the casing is reinforced with 20mm-spaced annular ribs to enhance its resistance to deformation and withstand impacts during tying operations. A clamp mounting cavity at the front allows for quick assembly and disassembly; a drive assembly cavity (lined with shock-absorbing cotton) in the middle absorbs motor vibrations, reducing grip discomfort; and a power assembly mounting slot at the rear (compatible with a removable lithium battery) ensures secure installation of the power supply components, optimizing the overall structural layout and user experience.

[0035] A torque adjustment knob 21 is located on the outer side of the middle part of the housing. It is connected to the torque sensing module of the electric drive component through an internal gear meshing structure, and can adjust the torque from 5 to 30 N. Graded adjustment within the range of m (each grade interval 5N) During adjustment, the scale markings next to the knob clearly display the current torque value, adapting to the binding needs of cables of different diameters and preventing damage to the cable insulation layer due to excessive torque or loosening due to insufficient torque.

[0036] The front end of the housing is embedded with a high-brightness LED lamp 20 near the pliers head assembly. The illumination range covers the working area of ​​the pliers head (diameter ≥ 15cm), and the lighting intensity can meet the working needs of low-light environments below 5 lux. The side of the middle of the housing is equipped with a lighting switch 22, which is a push-button structure. Pressing it once turns on the lighting and pressing it again turns it off. It is easy to operate and ensures the visibility of the work when the light is insufficient.

[0037] A switch button 16 is located in the grip area of ​​the housing and adopts a three-stage sliding structure: pushing it forward activates the forward rotation mode, driving the tightening gear 19 to rotate forward to tighten the cable ties; pushing it backward activates the reverse rotation mode, driving the tightening gear 19 to rotate in the opposite direction to loosen the cable ties or cancel erroneous operations; the middle position is the stop mode, cutting off the power output. The switch surface is textured with anti-slip material to increase grip friction, prevent slippage when operating with wet hands, and improve operational safety.

[0038] (4) Portable adapter components Includes a magnetic block 9 and a wristband 13. The magnetic block 9 allows the device to be temporarily attached to a metal work surface, making it easy to retrieve and store in situations where the operating space is limited. The wristband 13 is ergonomically designed to fit different wrist sizes. Wearing it during operation can prevent the device from falling accidentally, improving the safety and portability of working at heights and in confined spaces, and expanding the adaptability of the device to various application scenarios.

[0039] (5) Power supply components Employing a removable lithium battery, it features fast charging and long battery life, providing a stable DC power supply for the electric drive components, lighting, and control circuits. The battery and the power component mounting slot in the housing are fitted with a foolproof structure, allowing for easy installation and removal, supporting hot-swap, ensuring power supply during continuous operation, solving the operational constraints of traditional cable power supply, and improving the mobility and operational flexibility of the device.

[0040] When working with the above technical solution, (a) Cable tie insertion Align the end of the cable tie to be tied with the cable tie guide 2 of the cable tie clamp body 1, so that the cable tie is accurately guided along the cable tie guide 2 onto the cutting platform 4, and further pushed into the cable tie slot 5 on the tightening member 6, ensuring that the cable tie is in a suitable tightening state in the slot, laying the foundation for subsequent binding operations.

[0041] (II) Power Starting and Transmission Depending on the ambient lighting conditions, if in a low-light environment (such as inside a cabin or in the shadow of equipment), press the lighting switch 22 to turn on the lighting lamp 20 to illuminate the area where the clamps are working; depending on the diameter of the cable to be bound, rotate the torque adjustment knob 21 to the corresponding torque setting (e.g., 15N for a 10mm diameter cable). (m), confirm the current setting through the scale markings.

[0042] Operate the switch button 16 on the housing 15: Push it forward to the forward rotation position. At this time, the removable lithium battery 8 is used as a power source to supply power to the motor unit 12. After the motor unit 12 starts, it drives the transmission unit 11 to operate. The transmission unit 11 transmits power to the reducer output shaft 14 through the output unit 10. At the same time, the torque sensing module monitors the output torque in real time and automatically maintains a stable output when the preset value is reached.

[0043] To pause operation, move switch button 16 to the middle stop position; to loosen the cable ties (if cable tie misalignment is detected), push switch button 16 backward to the reverse position, driving the tightening gear 19 to rotate in the opposite direction, loosening the cable ties for adjustment. Precise coordination of all components ensures efficient power transmission and operational controllability, providing stable support for cable tie tightening.

[0044] (iii) Tighten the cable ties The reducer output shaft 14 receives power and rotates, which in turn drives the tightening gear 19 to rotate synchronously. The tightening gear 19 is adapted and linked with the tightening component 6. The reducer output shaft 14 drives the first bevel gear 17 to rotate, and the first bevel gear 17 meshes with the second bevel gear 18. The second bevel gear 18 drives the tightening gear shaft 23 to rotate, which in turn drives the tightening gear 19 and the external tightening component 6 to rotate, thereby achieving the rotational tightening of the cable tie. Driven by the tightening gear 19, the tightening component 6 begins to rotate, continuously applying a tightening force to the cable tie in the cable tie slot 5, causing the cable tie to gradually tighten until it reaches a state that fits the bound object and meets the binding tightness requirements. During this process, the tightening action is ensured to be stable and precise.

[0045] (iv) Cable tie cutting Once the cable tie is tightened to the appropriate position, raising the operating lever 7 triggers the cutter 3, causing it to act on the cutting platform 4. The cutter 3 quickly and precisely cuts off the excess cable tie at the cable tie slot 5, completing the final cut of the cable tie. This concludes the entire cable tie binding operation. The precise matching of the upward stroke of the operating lever 7 with the cutting motion of the cutter 3 ensures effective cutting and avoids issues such as cable tie residue or incomplete cutting.

[0046] The pliers head assembly and the electric drive assembly feature a dual connection structure of "snap-fit ​​+ bolt". The straight-line body housing (280mm in length, 55mm in diameter) and streamlined design significantly improve operational flexibility in the confined spaces of a ship compared to existing L-shaped tools, allowing for 360° rotation. The combination of a wrist strap and magnetic block solves the problem of temporary tool storage: the wrist strap prevents slippage during operation, and the magnetic block allows the tool to be attached to the steel plate surface.

[0047] The coaxial mounting structure of the brushless motor and planetary gear reducer, combined with a lithium battery, improves efficiency compared to manual tools and is suitable for environments ranging from -20℃ to 60℃, including humid and dusty conditions. The modular design (clamping head and battery can be independently removed) facilitates maintenance and replacement, reducing maintenance costs. The torque adjustment function allows for precise control of binding force according to cable specifications, reducing operational defects caused by improper force and expanding applicability to various cable types. The combination of a lighting lamp and switch solves the problem of blind spots in low-light environments, significantly improving visibility in scenarios such as ship cabins and equipment shadow areas. A three-position switch allows for convenient switching between forward, reverse, and stop functions, reducing misoperation, especially when adjusting cable tie tightness; it allows for quick correction without disassembly, further improving work efficiency and safety.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
