Description

Technical Field

[0001] This utility model relates to the field of cable cutting technology, specifically a cable cutter. Background Technology

[0002] Cables are an important component in fields such as power, communications, construction, and industrial manufacturing. Cables include wires, cables, and optical fibers. During the cable laying process, cables need to be cut according to the actual laying requirements. For some small-diameter cables, workers can use wire cutters or scissors to cut them. However, for some relatively large-diameter cables, due to their larger diameter and strength, scissors or wire cutters are not suitable, so special cutters are required for cutting.

[0003] For cable cutting, authorization announcement number CN221709310U proposes a cable cutting device, which includes a base plate assembly, two mounting assemblies, two clamping assemblies and two blade assemblies. The device uses a hydraulic cylinder to drive the two sets of blades to move relative to each other to cut the cable.

[0004] While the aforementioned device can cut cables, its power relies entirely on hydraulic energy provided by a hydraulic system. This means the device must be connected to a hydraulic system to operate properly. However, carrying a hydraulic system is extremely inconvenient in cable laying operations, increasing the complexity of equipment transportation and potentially being limited by the space and environmental conditions of the construction site. This strong dependence on a specific auxiliary system directly results in the device's poor applicability; it can only function in fixed construction sites equipped with hydraulic systems and cannot meet the needs of outdoor, mobile cable laying operations.

[0005] To address these issues, we propose a cable cutter. Utility Model Content

[0006] The purpose of this invention is to provide a cable cutter to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A cable cutter includes a hollow box and a connecting hinge. A shaped base box is located below the hollow box. The shaped base box and the hollow box are connected at one end by the connecting hinge. An upper strip-shaped sliding hole communicating with the interior of the hollow box is opened at the upper end, and a lower strip-shaped sliding hole communicating with the interior of the hollow box is opened at the lower end. An inner slider is slidably connected inside the hollow box. A rack is fixedly connected to the bottom of the inner slider, and the rack is slidably connected to the lower strip-shaped sliding hole. A first return spring is installed between the inner slider and the end face of the hollow box away from the connecting hinge. Cutting components that cooperate with each other are provided at the upper end of the hollow box and the upper end of the inner slider. A driving component that cooperates with the rack to drive the cutting components to perform cutting is provided on the shaped base box.

[0009] As a further embodiment of this utility model: the side of the irregularly shaped bottom box opposite to the hollow box is also provided with an avoidance groove for avoiding the rack.

[0010] As a further embodiment of this utility model: the cutting assembly includes a fixed plate, which is fixedly connected to the upper end of the hollow box away from the connecting hinge. A movable plate is fixedly connected to the upper end of the inner slider away from the connecting hinge. Both the fixed plate and the movable plate are provided with cutting blades, and the cutting blades are fixed with screws.

[0011] As a further embodiment of this utility model: the driving component includes a mounting cavity, which is located in the middle of the irregularly shaped base box near the hollow box. A rotating shaft is rotatably connected inside the mounting cavity, and a gear is fixedly connected to the rotating shaft. The gear meshes with a rack. A rotating component for driving the rotating shaft to rotate is provided inside the mounting cavity. A fixing component for fixing to the hollow box is provided at the end of the irregularly shaped base box away from the connecting hinge.

[0012] As a further embodiment of this utility model: the rotating assembly includes a worm gear, which is fixedly connected to one end of the rotating shaft. A worm is rotatably connected to one side of the mounting cavity, and the worm meshes with the worm gear. A rotating disk is fixedly connected to the connecting shaft head at the lower end of the worm, which protrudes from the irregularly shaped bottom box.

[0013] As a further embodiment of this utility model: the fixing component includes two locking frames, which are respectively fixedly connected to the two sides of the lower end face of the hollow box away from the connecting hinge. The irregular bottom box is provided with a fastening component that cooperates with the locking frame at the end away from the connecting hinge.

[0014] As a further embodiment of this utility model: the fastening assembly includes a mounting groove, which is located on both sides of the end of the irregularly shaped base box. An L-shaped rod is slidably connected in the mounting groove. An inclined locking block that cooperates with the locking frame is fixedly connected to the upper end of the L-shaped rod. A second return spring is installed between the L-shaped rod and the vertical end face inside the mounting groove.

[0015] As a further improvement of this utility model, a pressing handle is fixedly connected to the end of the L-shaped rod away from the inclined locking block.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In the cutting process, this utility model uses a rotating disk to reduce speed and increase torque through a worm gear and worm wheel, and then transmits power to a gear. The gear then drives the rack and inner slider to move, which in turn drives the moving plate to move towards the fixed plate. The cutting blade then cuts the cable. After the worm gear and worm wheel reduce speed and increase torque, only rotating the rotating disk is needed to obtain a large thrust to move the moving plate and cut the cable. Therefore, it avoids the limitation of existing technologies that require a hydraulic system to work.

[0018] 2. This utility model can fix or separate the irregularly shaped bottom box through the set fastening component, so that after the cable is cut, the irregularly shaped bottom box can be opened to separate the rack and gear. After separation, the inner slider can be quickly reset under the action of the first reset spring, so that there is no need to rotate the rotating disk when resetting the inner slider, which greatly improves the convenience of operation.

[0025] 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.

[0026] Please see Figures 1-5 In this embodiment of the utility model, a cable cutter includes a hollow box 1 and a connecting hinge 9. A shaped bottom box 2 is provided below the hollow box 1. The shaped bottom box 2 and the hollow box 1 are connected together by a connecting hinge 9 at one end. The connecting hinge 9 allows the hollow box 1 and the shaped bottom box 2 to rotate relative to each other.

[0027] The upper end of the hollow box 1 has an upper strip-shaped sliding hole 7 communicating with the interior of the hollow box 1, and the lower end of the hollow box 1 has a lower strip-shaped sliding hole 12 communicating with the interior of the hollow box 1. An inner slider 14 is slidably connected inside the hollow box 1, and a rack 13 is fixedly connected to the bottom of the inner slider 14. The rack 13 is slidably connected to the lower strip-shaped sliding hole 12. A first return spring 11 is installed between the inner slider 14 and the end face of the hollow box 1 away from the connecting hinge 9. The side of the irregularly shaped bottom box 2 opposite to the hollow box 1 also has a avoidance groove 20 for avoiding the rack 13. During operation, the inner slider 14 can slide inside the hollow box 1 under the action of the driving component. When the inner slider 14 slides, it will drive the cutting component to work, realizing the cutting of the cable. At the same time, the first return spring 11 is used to quickly reset the inner slider 14 after the cable cutting is completed. During the cutting process, it is in a compressed state, storing elastic potential energy. After the gear 18 separates from the rack 13, it is released, driving the inner slider 14 and the moving plate 8 to return to the initial position, preparing for the next cable cutting.

[0028] The upper end of the hollow box 1 and the upper end of the inner slider 14 are provided with mutually cooperating cutting components. The cutting components include a fixed plate 6, which is fixedly connected to the end of the upper surface of the hollow box 1 away from the connecting hinge 9. A movable plate 8 is fixedly connected to the end of the upper surface of the inner slider 14 away from the connecting hinge 9. Both the fixed plate 6 and the movable plate 8 are provided with cutting blades 10, which are fixed with screws. During cutting, the drive component will drive the movable plate 8 to move towards the fixed plate 6. When the movable plate 8 moves towards the fixed plate 6, the two cutting blades 10 will come together and eventually close, thus cutting the cable. At the same time, the cutting blades 10 are fixed with screws, which makes it convenient to replace the cutting blades 10 after they wear out.

[0029] The irregularly shaped base box 2 is provided with a driving component that works with the rack 13 to drive the cutting assembly for cutting. The driving component includes a mounting cavity 17, which is located in the middle of the irregularly shaped base box 2 near the hollow box 1. A rotating shaft 16 is rotatably connected inside the mounting cavity 17, and a gear 18 is fixedly connected to the rotating shaft 16. The gear 18 meshes with the rack 13. The mounting cavity 17 is provided with a rotating component for driving the rotating shaft 16 to rotate. During operation, the rotating component drives the rotating shaft 16 to rotate, which in turn drives the gear 18 to rotate. The rotation of the gear 18 drives the rack 13, thereby causing the inner slider 14 to slide inside the hollow box 1. After the inner slider 14 moves, it can drive the moving plate 8 and the cutting blade 10 to move accordingly.

[0030] The rotating assembly includes a worm gear 19, which is fixedly connected to one end of the rotating shaft 16. A worm 15 is rotatably connected to one side of the mounting cavity 17, and the worm 15 meshes with the worm gear 19. A rotating disk 3 is fixedly connected to the lower end of the worm 15, which protrudes from the irregularly shaped base box 2. When the rotating shaft 16 is driven to rotate, rotating the rotating disk 3 causes the worm 15 to rotate. The rotation of the worm 15 drives the worm gear 19 to rotate, and the rotation of the worm gear 19 drives the rotating shaft 16 to rotate. After the worm 15 and worm gear 19 reduce speed and increase torque, a large driving force can be obtained by rotating the rotating disk 3 alone, thereby meeting the requirements for cutting cables.

[0031] The irregularly shaped bottom box 2 has a fixing component at the end away from the connecting hinge 9 for fixing to the hollow box 1; the fixing component includes two locking frames 4, which are respectively fixedly connected to both sides of the lower end face of the hollow box 1 away from the connecting hinge 9; the irregularly shaped bottom box 2 has a fastening component that cooperates with the locking frames 4 at the end away from the connecting hinge 9; the fastening component includes a mounting groove 21, which is opened on both sides of the end of the irregularly shaped bottom box 2, and an L-shaped rod 5 is slidably connected in each mounting groove 21. The upper end is fixedly connected with a sloping locking block 22 that cooperates with the locking frame 4. A second return spring 23 is installed between the L-shaped rod 5 and the vertical end face inside the mounting groove 21. A pressing handle is fixedly connected to the end of the L-shaped rod 5 away from the sloping locking block 22. When it is necessary to separate the gear 18 from the rack 13, the sloping locking block 22 is moved towards the middle of the irregular bottom box 2 by pressing the two pressing handles. After moving, the sloping locking block 22 will disengage from the locking frame 4. Then, the irregular bottom box 2 and the hollow box 1 are rotated relative to each other, thereby realizing the separation of the gear 18 from the rack 13.

[0032] The working principle of this utility model is as follows: In use, the cable to be cut is placed between the two cutting blades 10. Then, the rotating disk 3 is rotated. The rotation of the rotating disk 3 drives the worm gear 15, which in turn drives the worm wheel 19. The worm wheel 19 drives the rotating shaft 16, which in turn drives the gear 18. The gear 18 meshes with the rack 13, thereby driving the inner slider 14 to slide towards the fixed plate 6 inside the hollow box 1. The movement of the inner slider 14 causes the moving plate 8 to move. When the moving plate 8 moves towards the fixed plate 6, the two cutting blades 10 will approach each other and eventually close, thus cutting the cable. After cutting, pressing the two pressing handles moves the inclined locking block 22 towards the center of the irregular bottom box 2. After moving, the inclined locking block 22 will disengage from the locking frame 4. Then, the irregular bottom box 2 and the hollow box 1 will rotate relative to each other, which can separate the gear 18 from the rack 13. After the gear 18 and the rack 13 are separated, the inner slider 14 loses its restriction and can be reset under the action of the first reset spring 11. Then, the irregular bottom box 2 is closed and the inclined locking block 22 is locked into the locking frame 4. After the irregular bottom box 2 is closed, the gear 18 re-engages with the rack 13, and then the next cable cutting can be performed.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Although this specification describes embodiments, not every embodiment contains only one technical solution. This method of description is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
