Description

Technical Field

[0001] This utility model belongs to the field of tool technology, specifically relating to a portable multifunctional optical cable stripping tool. Background Technology

[0002] As the core transmission medium of modern communication networks, the efficiency of fiber optic cable stripping directly affects the timeliness of communication repair and maintenance. With the expansion of fiber optic network coverage, fiber optic cable stripping tools, with their advantages of precise cutting and layered stripping, play a vital role in improving work efficiency and ensuring fiber core integrity, gradually becoming essential tools in the field of communication engineering. However, fiber optic cables are typically composed of multiple layers, including an outer sheath, protective layer, loose tube, and coating layer. The material properties of each layer differ significantly, placing higher demands on the adaptability of the stripping process. Traditional manual operations are insufficient to meet the requirements of high efficiency and low damage.

[0003] To optimize optical cable stripping technology, existing patents such as CN118778198A disclose an integrated stripping device. This solution uses an operating table with a feeding trough, splitting component, and slitting component. A transmission system drives a prismatic cutter head to perform helical cutting, and a rubbing roller assembly is configured to relieve stress on the protective sheath. Theoretically, this can achieve an automated stripping process. Specifically, after the optical cable is positioned, a servo motor drives a gear transmission system, which, in conjunction with an electric telescopic rod, adjusts the cutter stroke. Mechanical twisting reduces the adhesion of the adhesive layer, thereby improving the cutting machine's processing efficiency. However, in-depth analysis reveals significant limitations: First, its overall structure relies on a fixed operating table and multiple sets of electric actuators, making rapid deployment difficult during field repairs. Furthermore, continuous force is required to propel the optical cable during operation, placing high demands on the operator's physical strength, especially for female technicians operating independently. Second, although the device integrates multiple functional modules, it still requires specialized cutting tools to process different sheaths, resulting in a wide variety of tools that are bulky and do not meet the portability and mobility requirements for field operations.

[0004] It is evident that existing fiber optic cable stripping technologies suffer from both insufficient human-machine interaction efficiency and low tool integration. Especially in complex field conditions, traditional equipment cannot overcome the operational obstacles caused by labor dependence, nor is it easily portable. Therefore, to address the specific needs of fiber optic cable emergency repair scenarios, there is an urgent need to develop a portable stripping tool that combines lightweight structure, labor-saving operation mechanism, and multi-functional integration to overcome existing technological bottlenecks and enhance emergency communication support capabilities. Summary of the Invention

[0005] In response to the problems in related technologies, this utility model proposes a portable multifunctional optical cable stripping tool to solve the technical problems of traditional optical cable stripping tools being bulky and having low integration.

[0006] The technical solution of this utility model is achieved as follows: a portable multi-functional optical cable stripping tool, comprising:

[0007] The handle includes a scale tube that extends through the center and a fine-tuning lever that is helically sleeved with the scale tube. The upper part of the fine-tuning lever passes through the through-hole of the scale tube along its axial direction and is detachably connected to the cutter head. The lower part of the fine-tuning lever is provided with a drive unit that is connected to the cutter head for driving the cutter head to rotate around its central axis. The cutter head moves along the axial direction of the scale tube with the fine-tuning lever.

[0008] The bracket includes a base end and a cantilever end; the base end is detachably connected to the scale tube body; the cantilever end extends freely from the base end to above the cutter head;

[0009] A guide wheel assembly is mounted on the cantilever end of a bracket; the guide wheel assembly includes a pulley and an adjustment part for driving the pulley to move up and down; the pulley corresponds to the cutter head and is used to guide the stripping and passing of the optical cable.

[0010] This invention is portable and easy to operate. The drive unit rotates the cutter head, and the guide wheel assembly guides the movement, enabling precise stripping without continuous force. At the same time, it integrates multiple functional cutters into one unit, and the cutter head can be detached and replaced with corresponding special cutting cutters to process different optical cable sheaths, achieving a balance between portability and multifunctionality.

[0011] As a further improvement to the above solution, the fine-tuning lever is provided with a shaft portion that passes through the through-hole of the scale tube. A first thread is provided on the inner wall of the scale tube, and a second thread is provided on the shaft portion. The fine-tuning lever is engaged with the first thread of the scale tube via the second thread. The threaded engagement between the shaft portion of the fine-tuning lever and the scale tube converts rotational motion into linear motion with high transmission accuracy. The operator can precisely control the feed amount of the cutter head along the axial direction of the scale tube by rotating the fine-tuning lever, thereby achieving precise adjustment of the optical cable stripping depth. This meets the requirements of different optical cable structures and stripping conditions, effectively avoiding problems such as optical cable damage or incomplete stripping caused by excessive or insufficient feed, and improving the quality and reliability of optical cable stripping.

[0012] As a further improvement to the above solution, the upper end of the rod shaft is detachably connected to the cutter head, and its lower end is provided with a shank.

[0013] The rotating handle includes a rotating handle body with a hollow accommodating cavity, within which the drive unit is housed. The rod shaft portion has a through groove along its central axis, communicating with the accommodating cavity. The drive unit includes a motor, the output of which drives a transmission rod. The transmission rod passes through the through groove and is detachably connected to the cutter head. The upper end of the rod shaft portion is detachably connected to the cutter head, making cutter head replacement and installation more convenient. This allows for quick replacement of suitable cutter heads according to different optical cable types and stripping requirements, thereby achieving the integration and switching of multiple functions. Furthermore, the drive unit housed within the accommodating cavity of the rotating handle, driving the transmission rod via a motor to rotate the cutter head, achieves a tight integration of power transmission and the cutter head. This not only saves space but also provides a basis for diverse cutter head designs, facilitating the integration of more functions such as cutting, stripping, and grinding to meet complex operational needs.

[0014] As a further improvement to the above solution, the handle also includes a sleeve, which extends upward from the top of the handle body along the circumferential edge and is fitted onto the outer wall of the scale tube; the upper edge of the sleeve and the outer wall of the scale tube are both provided with scale markings.

[0015] As a further improvement to the above solution, the base end of the bracket is provided with a mounting groove, and the upper part of the scale tube body is connected to the mounting groove. It also includes a locking member, which penetrates the base end perpendicular to the mounting groove to lock the bracket onto the scale tube body. Through the connection between the mounting groove at the base end of the bracket and the scale tube body, and the locking function of the locking member, the bracket can be quickly installed or removed. This design allows the tool to be stably supported by the bracket when guided by guide wheels; and when used in the field or for portable operation, the bracket can be detached for direct use as a power tool, greatly improving the tool's versatility and flexibility.

[0016] As a further improvement to the above solution, the adjusting part includes a screw; the lower end of the screw is rotatably connected to a U-shaped frame along its axial direction, and the pulley is provided on the U-shaped frame; the middle end of the screw passes through the cantilever end and is threadedly engaged with the cantilever end; the upper end of the screw protrudes outside the cantilever end, and the protruding part is provided with a handle;

[0017] The cantilever end is also equipped with a limiting block near the side of the U-shaped frame. When the screw is rotated, the U-shaped frame is driven to move up and down, and the U-shaped frame slides against the limiting block. Through the threaded engagement between the screw and the cantilever end, rotating the handle allows the U-shaped frame to move up and down, thereby adjusting the position of the pulley. This adjustment method is simple to operate and can precisely control the distance between the pulley and the cutter head to accommodate optical cables of different diameters, ensuring smooth passage of the optical cable during stripping and improving stripping efficiency and quality.

[0018] As a further improvement to the above solution, the screw is provided with a first locking platform and a second locking platform at intervals from bottom to top, and the U-shaped bracket is installed between the first locking platform and the second locking platform;

[0019] Alternatively, the screw may have a first clamping platform and a second clamping platform spaced apart from bottom to top, with the U-shaped frame positioned between the first and second clamping platforms. An elastic unit is also provided between the upper end face of the U-shaped frame and the lower end face of the second clamping platform. By providing an elastic unit between the U-shaped frame and the screw, a stable elastic preload can be provided to the pulley, effectively avoiding impact, ensuring the contact stability between the pulley and the optical cable, and improving the reliability of the stripping process.

[0020] As a further improvement to the above solution, the cutter head includes a cutter holder and a cutter head body; the cutter holder is provided with external threads, and the fine-tuning rod handle is provided with corresponding external threads, and the two are connected to each other.

[0021] Alternatively, the tool holder may be provided with a prism, and the fine-tuning rod handle may be provided with a corresponding groove, the two of which cooperate with each other and are fixedly connected by fastening screws.

[0022] As a further improvement to the above solution, at least one button is provided on the side wall of the handle. The button is used to control the start and stop of the drive unit, and to control the speed up or slow down of the rotation of the output shaft of the drive unit. A USB charging port and a charging indicator light are also provided at the bottom of the handle.

[0023] As a further improvement to the above solution, the cutting head includes an optical cable outer sheath stripping cutting head, a protective layer stripping cutting head, a loose tube stripping cutting head, a coating layer stripping cutting head, or a screwdriver head. By changing the cutting head, operators can quickly switch the stripping function according to actual needs. Different cutting heads are designed for specific sheath layers, which can effectively avoid the problems of incomplete stripping or damage to the optical cable caused by the single cutting head design of traditional tools.

[0024] Beneficial effects:

[0025] (1) High portability and easy field deployment: It abandons the complex structure of traditional optical cable stripping devices that rely on fixed operating tables and multiple sets of electric actuators, and the overall design is more compact and lightweight. Its handle, bracket and guide wheel assembly are cleverly combined, which makes it easy for operators to carry to the field repair site. There is no need to carry heavy equipment, and the work can be carried out quickly, which greatly improves the timeliness and efficiency of optical cable field repair and meets the emergency needs in different environments.

[0026] (2) Effortless operation and reduced physical requirements: Through the fine-tuning feed of the fine-tuning lever, the drive unit drives the blade head to rotate, and the guide wheel assembly guides the movement, the operator can achieve precise peeling without continuous force, which significantly reduces the dependence on the operator's physical strength and broadens the scope of application for operators.

[0027] (3) High integration and wide applicability: It integrates multiple functional cutting tools into one, and the cutting head can be detached and replaced with corresponding special cutting tools to process different optical cable sheaths, realizing the unity of portability and multifunctionality, which meets the requirements of field operations for portable and mobile tools.

[0051] 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 a part of the embodiments of the present utility model, and not all of them. 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.

[0052] Example 1

[0053] like Figures 1-6 As shown, this embodiment provides a portable multi-functional optical cable stripping tool, including a handle 1, a bracket 2, and a guide wheel assembly 3.

[0054] Specifically, the handle 1 includes a scale tube 11 that extends through the center, and a fine-tuning lever 12 that is helically connected to the scale tube 11; the upper part of the fine-tuning lever 12 passes through the through-hole of the scale tube 11 along its axial direction and is detachably connected to the cutter head 13; specifically, the cutter head 13 includes a cutter holder 131 and a cutter head body 132; the cutter holder 131 is provided with external threads, and the fine-tuning lever 12 is provided with corresponding external threads, and the two are connected to each other.

[0055] In this embodiment, the cutting head 13 includes an optical cable outer sheath stripping cutting head 13a, a protective layer stripping cutting head 13b, a loose tube 1222 stripping cutting head 13, a coating layer stripping cutting head 13d, or a screwdriver head 13e. The optical cable outer sheath stripping cutting head 13a and the screwdriver head 13e are powered by the drive unit 14 to rotate, thereby improving the efficiency of stripping or screwing. The protective layer stripping cutting head 13b, the loose tube 1222 stripping cutting head 13, and the coating layer stripping cutting head 13d do not require power from the drive unit 14 to rotate; their cutting head bodies 132 have sharp blades and can directly slide to strip the corresponding optical cable sheath. In this embodiment, by changing the cutting head 13, the operator can quickly switch stripping functions according to actual needs. Different cutting heads 13 are designed for specific sheath layers, effectively avoiding the problems of incomplete stripping or damage to the optical cable caused by the design of a single cutting head 13 in traditional tools. The lower part of the fine-tuning lever 12 is provided with a drive unit 14 that is connected to the cutter head 13 for driving the cutter head 13 to rotate around its central axis; the cutter head 13 moves axially along the scale tube 11 with the fine-tuning lever 12.

[0056] In this embodiment, the fine-tuning lever 12 has a lever shaft portion 121, which passes through the through-hole of the scale tube 11. A first thread 111 is provided on the inner wall of the scale tube 11, and a second thread 1211 is provided on the lever shaft portion 121. The fine-tuning lever 12 is engaged with the first thread 111 of the scale tube 11 via the second thread 1211. The threaded engagement between the lever shaft portion 121 and the scale tube 11 allows for the conversion of rotational motion into linear motion with high transmission accuracy. The operator can precisely control the feed amount of the cutter head 13 along the axial direction of the scale tube 11 by rotating the fine-tuning lever 12, thereby achieving precise adjustment of the optical cable stripping depth. This meets the requirements of different optical cable structures and stripping conditions, effectively avoiding problems such as optical cable damage or incomplete stripping due to excessive or insufficient feed, and improving the quality and reliability of optical cable stripping.

[0057] In this embodiment, the upper end of the rod shaft portion 121 is detachably connected to the cutter head 13, and its lower end is provided with a rotating handle portion 122. The rotating handle portion 122 includes a rotating handle body 1221, which has a hollow accommodating cavity Q1. The driving unit 14 is disposed within the accommodating cavity Q1. The rod shaft portion 121 has a through groove C1 along its central axis, and the through groove C1 communicates with the accommodating cavity Q1. The driving unit 14 includes a motor, and the output end of the motor drives a transmission rod 15. The transmission rod 15 passes through the through groove C1 and is detachably connected to the cutter head 13. The detachable connection between the upper end of the rod shaft portion 121 and the cutter head 13 makes the replacement and installation of the cutter head 13 more convenient, allowing for quick replacement of the appropriate cutter head 13 according to different optical cable types and stripping requirements, thereby realizing the integration and switching of multiple functions. In addition, a drive unit 14 is installed in the cavity Q1 of the rotating handle 122. The drive rod 15 is driven by a motor to rotate the cutter head 13, realizing the close integration of power transmission and cutter head 13. This not only saves space, but also provides a basis for the diversified design of the cutter head 13, making it easy to integrate more functions, such as cutting, peeling, and grinding, to meet the needs of complex operations.

[0058] In this embodiment, the handle portion 122 further includes a sleeve 1222, which extends upward from the top of the handle body 1221 along its circumferential edge and is fitted onto the outer wall of the scale tube 11. Scale markings are provided at the upper edge of the sleeve 1222 and on the outer wall of the scale tube 11. In this embodiment, at least one button 4 is provided on the side wall of the handle 1. The button 4 is used to control the start and stop of the drive unit 14, and to control the speed of rotation of the output shaft of the drive unit 14. A USB charging port 5 and a charging indicator light 6 are also provided at the bottom of the handle 1.

[0059] The bracket 2 is C-shaped, including a base end 21 and a cantilever end 22. The base end 21 is detachably connected to the scale tube 11. The cantilever end 22 extends freely from the base end 21 to above the blade head 13. In this embodiment, the base end 21 of the bracket 2 is provided with a mounting groove 211, and the upper part of the scale tube 11 is connected to the mounting groove 211. It also includes a locking member 212, which penetrates the base end 21 in a direction perpendicular to the mounting groove 211 to lock the bracket 2 onto the scale tube 11. Through the connection between the mounting groove 211 of the base end 21 and the scale tube 11, and the locking function of the locking member 212, the bracket 2 can be quickly installed or removed. This design allows the tool to be stably supported by the bracket 2 when guided by a guide wheel; and when used in the field or for portable operation, the bracket 2 can be detached and used directly as a power tool, greatly improving the tool's versatility and flexibility.

[0060] The guide wheel assembly 3 is mounted on the cantilever end 22 of the bracket 2; the guide wheel assembly 3 includes a pulley 31 and an adjustment part 32 for driving the pulley 31 to move up and down; the pulley 31 corresponds to the cutter head 13 and is used to guide the stripping and passing of the optical cable.

[0061] In this embodiment, the adjusting part 32 includes a screw 321; the lower end of the screw 321 is rotatably connected to a U-shaped frame 322 along its axial direction, and the pulley 31 is provided on the U-shaped frame 322; the middle end of the screw 321 passes through the cantilever end 22 and is threadedly engaged with the cantilever end 22; the upper end of the screw 321 protrudes outside the cantilever end 22, and the exposed part is provided with a handle 323, which can be a quincunx handle 323.

[0062] The cantilever end 22 is also provided with a limiting block 221 on the side near the U-shaped frame 322. When the screw 321 is rotated, the U-shaped frame 322 is driven to move up and down, and the U-shaped frame 322 slides against the limiting block 221. Through the threaded engagement between the screw 321 and the cantilever end 22, the U-shaped frame 322 can be moved up and down by rotating the handle 323, thereby adjusting the position of the pulley 31. This adjustment method is simple to operate and can precisely control the distance between the pulley 31 and the cutter head 13 to accommodate optical cables of different diameters, ensuring smooth passage of the optical cable during the stripping process and improving stripping efficiency and quality.

[0063] The screw 321 is provided with a first locking platform 324 and a second locking platform 325 spaced apart from bottom to top. The U-shaped frame 322 is located between the first locking platform 324 and the second locking platform 325, and an elastic unit 326 is provided between the upper end face of the U-shaped frame 322 and the lower end face of the second locking platform 325. Specifically, the elastic unit 326 can be a compression spring.

[0064] By setting an elastic unit 326 between the U-shaped frame 322 and the screw 321, a stable elastic preload can be provided to the pulley 31, effectively avoiding impact, ensuring the contact stability between the pulley 31 and the optical cable, and improving the reliability of the stripping process.

[0065] With the above-described solution of this utility model, when stripping the optical cable:

[0066] First, attach the corresponding fiber optic cable sheath stripping head 13 (such as fiber optic cable outer sheath stripping head 13a). By rotating the fine-tuning lever 12, feed the head 13 to the appropriate scale. This multi-functional fiber optic cable stripping tool integrates multiple functional blades into one unit. The head 13 can be detached and replaced with corresponding dedicated cutting blades to process different fiber optic cable sheaths, achieving a balance between portability and multi-functionality, meeting the requirements of portable and mobile tools for field operations.

[0067] Then, the optical cable is passed between the pulley 31 and the cutter head 13. The distance between the pulley 31 and the optical cable is adjusted by rotating the screw 321. With the drive unit 14 driving the cutter head 13 to rotate and the guide wheel assembly 3 guiding the passage, the operator can achieve precise stripping without continuous force, which significantly reduces the dependence on the operator's physical strength and broadens the scope of application for operators.

[0068] The portable multifunctional optical cable stripping tool provided in this embodiment is easy to operate. The drive unit 14 drives the cutter head 13 to rotate, and the guide wheel assembly 3 guides the movement, so precise stripping can be achieved without continuous force. At the same time, multiple functional cutters are integrated into one unit, and the cutter head 13 can be detached and replaced with corresponding special cutting cutters to process different optical cable sheaths, thus achieving a balance between portability and multifunctionality.
