Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to a cable armor stripping tool that prevents damage to the wire core. Background Technology

[0002] To ensure stable operation of cables, protective layers are installed, including an outer sheath, armor layer, and inner lining. These structures are designed to protect the cable and are not conductive themselves. Therefore, when connecting cables, the protective layers at the ends need to be removed to expose the internal conductors and achieve an effective electrical connection.

[0003] When stripping the protective layer from cable ends, the common on-site method is to cut and separate the outer sheath of the cable with a utility knife. Therefore, this method can only cut the outer sheath. For example, the Chinese utility model patent disclosed in publication number CN223680656U, "A Handheld Cable Stripper," uses two hinged semi-circular clamping blocks with stripping blades on each block. This allows the stripper to be held in the palm of one hand during stripping, and the two mounting cylinders can be positioned separately... While the outer sheath of a cable can be cut using fingers, this method can only cut radially. Furthermore, the cut outer sheath needs to be separated from the main structure of the cable's outer sheath, thus failing to achieve the desired function. Additionally, after the outer sheath is peeled off, some of the internal armor is made of metal, requiring a cutting saw to make an incision in the armor before using a screwdriver or other tools to pry it off from the main body of the cable armor. This makes the separation process cumbersome and inefficient. Utility Model Content

[0004] The purpose of this utility model is to provide a cable armor stripping tool that prevents damage to the wire core. It can adjust the length and direction of the stripping blade and can sequentially cut the outer sheath and saw the armor layer of the cable without the need to switch between multiple tools, thereby improving the cable stripping efficiency and effectively solving the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cable armor stripping tool for preventing damage to the core wires includes an upper base and a lower base. Two connecting rods are fixedly connected between the upper and lower bases, and a slider is provided between the two connecting rods. A lead screw is fixedly connected to the slider, and two sliding holes are formed inside the slider. The sliding holes are slidably connected to one of the connecting rods. A first fixed seat is fixedly connected to the front side of the slider. An adjusting sleeve is movably connected inside the first fixed seat, and a knife handle is movably connected inside the adjusting sleeve. A stripping knife is fixedly connected to the lower end of the knife handle, and a first dial is rotatably connected to the adjusting sleeve. A second fixed seat is fixedly connected to the front side of the lower base, and a saw handle is movably connected inside the second fixed seat. A saw blade is fixedly connected to the saw handle, and a second dial is rotatably connected to the lower end of the second fixed seat.

[0007] As a further preferred embodiment of this utility model, a movable handle is rotatably connected to the upper base. The movable handle has a threaded groove and is threadedly connected to the lead screw. When the movable handle is manually rotated, the threaded groove in the movable handle can rotate on the lead screw. Thus, the lead screw can push and pull the slider between the two connecting rods. A fixed handle is fixedly connected to the lower end of the lower base.

[0008] As a further preferred embodiment of this utility model, the lower base and the slider are respectively provided with V-shaped grooves on opposite sides, and clamping wheels are rotatably connected to both sides of the V-shaped grooves. The slider and the lower base can be clamped on the outside of the cable by several clamping wheels provided on opposite sides, and the entire device can be used to clamp and rotate on the outside of the cable.

[0009] As a further preferred embodiment of this utility model, the first fixing seat is provided with an installation groove, the inner side of the installation groove is provided with two annular adjustment grooves, and the top of the adjustment groove is provided with several limiting grooves.

[0010] As a further preferred embodiment of this utility model, a first radial channel is provided inside the adjusting sleeve. The transverse cross-section of the first radial channel is the same as the transverse cross-section of the knife handle. Several limiting blocks are fixedly connected to the outside of the adjusting sleeve. The adjusting sleeve is inserted into the mounting groove. A compression spring is inserted into the bottom of the adjusting sleeve and the adjusting groove. The limiting block is engaged in one of the limiting grooves. When the stripping knife and the slider are in a horizontal position, the slider and the lower base can clamp the outside of the cable and cut the outer protective sheath of the cable in a ring shape. Then, the cutting direction of the stripping knife can be adjusted by pressing down the adjusting sleeve with the knife handle and rotating the adjusting sleeve in the mounting groove, thereby cutting the part of the cable protective sheath after it is cut off, so as to facilitate the separation and removal of the excess protective sheath on the outside of the cable.

[0011] As a further preferred embodiment of this utility model, the four outer corners of the knife handle are arc-shaped and the connecting line is annular and threadedly connected to the screw hole in the first dial wheel. Thus, when the first dial wheel is rotated, the first dial wheel rotates on the adjusting sleeve and causes the screw hole in the first dial wheel to rotate on the threads of the four outer corners of the knife handle, thereby controlling the vertical movement of the knife handle in the first radial channel, thereby realizing the storage and extension length adjustment of the peeling knife.

[0012] As a further preferred embodiment of this utility model, a second radial channel is provided in the second fixed base. The transverse cross-section of the second radial channel is the same as the transverse cross-section of the saw handle. The four outer corners of the saw handle are arc-shaped and the connecting line is annular and threadedly connected to the screw hole in the second dial. After the protective sheath of the cable is stripped, the stripping knife can be stored in the adjusting sleeve through the knife handle, and the saw blade can be moved out through the second dial and the saw handle. Thus, the lower base and the slider clamp the cable on the outside and make the saw blade abut against the outside of the cable armor to achieve the cutting process of the cable armor.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the first dial can adjust the length of the stripping blade, and pressing down and rotating the adjusting sleeve can switch the cutting direction, thus realizing both circumferential and radial cutting of the cable protective sheath, which facilitates the stripping of the sheath. The second dial, in conjunction with the saw handle, controls the extension and retraction of the saw blade, which can cut the metal armor circumferentially, thereby integrating the functions of outer sheath stripping and armor layer cutting. This eliminates the need for frequent tool changes, simplifies the operation process, makes the operation controllable, and effectively avoids damage to the wire core. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-5 As shown, this utility model provides a cable armor stripping tool for preventing damage to the core wire, including an upper base 1 and a lower base 2. Two connecting rods 3 are fixedly connected between the upper base 1 and the lower base 2. A slider 4 is provided between the two connecting rods 3. A lead screw 5 is fixedly connected to the slider 4. Two sliding holes 6 are opened in the slider 4. The sliding holes 6 are slidably connected to one of the connecting rods 3. A first fixed seat 8 is fixedly connected to the front side of the slider 4. An adjusting sleeve 9 is movably connected to the first fixed seat 8. A knife handle 10 is movably connected to the adjusting sleeve 9. A stripping knife 11 is fixedly connected to the lower end of the knife handle 10. A first dial wheel 12 is rotatably connected to the adjusting sleeve 9. A second fixed seat 13 is fixedly connected to the front side of the lower base 2. A saw handle 14 is movably connected to the second fixed seat 13. A saw blade 15 is fixedly connected to the saw handle 14. A second dial wheel 16 is rotatably connected to the lower end of the second fixed seat 13.

[0023] like Figure 1 As shown, a movable handle 17 is rotatably connected to the upper base 1. The movable handle 17 has a threaded groove and is threadedly connected to the lead screw 5. When the movable handle 17 is manually rotated, the threaded groove in the movable handle 17 can rotate on the lead screw 5. Thus, the lead screw 5 can push and pull the slider 4 between the two connecting rods 3. A fixed handle 18 is fixedly connected to the lower end of the lower base 2. V-shaped grooves 22 are respectively opened on the opposite side of the lower base 2 and the slider 4. Clamping wheels 7 are rotatably connected to both sides of the V-shaped grooves 22. The slider 4 and the lower base 2 can be clamped on the outside of the cable by several clamping wheels 7 set on the opposite side, so as to realize the function of clamping and rotating the entire device on the outside of the cable.

[0024] like Figures 2-4As shown, the first fixed base 8 has a mounting groove 19, and two annular adjustment grooves 20 are formed inside the mounting groove 19. Several limiting grooves 21 are formed at the top of the adjustment grooves 20. The adjustment sleeve 9 has a first radial channel 24, and the transverse cross-section of the first radial channel 24 is the same as the transverse cross-section of the knife handle 10. Several limiting blocks 23 are fixedly connected to the outside of the adjustment sleeve 9. The adjustment sleeve 9 is inserted into the mounting groove 19. A compression spring 25 is inserted into the bottom of the adjustment sleeve 9 and the adjustment groove 20. The limiting block 23 is engaged in one of the limiting grooves 21. When the stripper 11 and the slider 4 are in a horizontal position, the slider 4 and the lower base 2 can be clamped on the outside of the cable to protect the outside of the cable. The protective sheath is cut in a ring shape. Then, the cutting direction of the peeling knife 11 can be adjusted by pressing down the adjusting sleeve 9 with the knife handle 10 and causing the adjusting sleeve 9 to rotate in the mounting groove 19. This cuts the part of the cable protective sheath that has been separated, making it easier to separate and remove the excess protective sheath from the outside of the cable. The four outer corners of the knife handle 10 are arc-shaped and the connecting line is a ring and threadedly connected to the screw hole in the first dial wheel 12. When the first dial wheel 12 is rotated, the first dial wheel 12 rotates on the adjusting sleeve 9 and causes the screw hole in the first dial wheel 12 to rotate on the thread on the four outer corners of the knife handle 10, thereby controlling the vertical movement of the knife handle 10 in the first radial channel 24, thus realizing the adjustment of the storage and protrusion length of the peeling knife 11.

[0025] like Figure 5 As shown, a second radial channel 26 is provided in the second fixed base 13. The transverse cross section of the second radial channel 26 is the same as the transverse cross section of the saw handle 14. The four outer corners of the saw handle 14 are arc-shaped and the connecting line is a ring and is threadedly connected to the screw hole in the second dial wheel 16. After the protective sheath of the cable is stripped, the stripping knife 11 can be stored in the adjusting sleeve 9 through the knife handle 10, and the saw blade 15 can be moved out through the second dial wheel 16 and the saw handle 14. Thus, the lower base 2 and the slider 4 clamp the cable on the outside and make the saw blade 15 abut against the outside of the cable armor to cut the cable armor.

[0026] It should be noted that this utility model is a cable armor stripping tool to prevent damage to the cable core. In use, first insert the lower base 2, slider 4, and the channel between the two lower bases 2 through one end of the cable to the position where stripping is required. Then, hold the movable handle 17 and the fixed handle 18 with both hands respectively. Then, rotate the movable handle 17, causing the screw groove inside the movable handle 17 to rotate on the screw 5. The screw 5 then pushes the slider 4 to slide along the connecting rod 3. Using the V-shaped groove 22 on the opposite side of the lower base 2 and slider 4, and the internal clamping wheel 7, the cable is securely clamped between them, allowing one end of the stripping blade 11 to insert into the outer sheath of the cable and abut against the outer side of the internal metal armor. Then, holding the movable handle 17 and the fixed handle 18 with both hands respectively, and using the clamping wheels 7 as fulcrums, the entire device rotates in a circle around the outside of the cable. Simultaneously, the stripping blade 11... 1. The outer sheath of the cable is cut and separated in a ring. Then, the movable handle 17 is rotated in the opposite direction, so that the movable handle 17 moves the slider 4 upward through the saw handle 14, and the stripping knife 11 is disengaged from the outer sheath of the cable. Then, the knife handle 10 is pressed down to drive the adjusting sleeve 9 to compress the compression spring 25. The limiting block 23 is disengaged from the original limiting groove 21. After the adjusting sleeve 9 is rotated to a suitable angle, it is released, and the limiting block 23 is locked into the corresponding limiting groove 21. Then, the movable handle 17 is rotated again, so that the screw groove in the movable handle 17 rotates in the screw rod 5. Then, the screw rod 5 pushes the slider 4 to slide along the connecting rod 3, so that the stripping knife 11 is adjusted and inserted into one end of the separated protective sheath. The entire tool is moved radially along the outer side of the separated protective sheath through the movable handle 17 and the fixed handle 18, so that the separated protective sheath is radially cut open, and the protective sheath can be peeled off.

[0027] When cutting the armor layer, rotate the first dial 12 in the opposite direction to retract the peeling knife 11 into the adjusting sleeve 9 to avoid interfering with subsequent operations. Then, rotate the second dial 16, whose screw hole engages with the outer thread of the saw handle 14, allowing the saw handle 14 to move within the second radial channel 26 of the second fixed seat 13. Subsequently, adjust the position of the slider 4 as described above, so that the slider 4 and the lower base 2 are again clamped on the outside of the cable by the clamping wheel 7 on the opposite side, and the cutting end of the saw blade 15 abuts against the outside of the metal armor. Rotate the tool to move circumferentially around the cable. During the rotation, the second dial 16 can be finely adjusted according to the change in cutting depth to control the saw handle 14 to drive the saw blade 15 to continuously abut against the outside of the metal armor with a certain pressure, so that the saw blade 15 can cut the armor layer smoothly without the need for additional tools.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
