Description

Technical Field

[0001] This invention relates to the field of cable stripping technology, and more specifically, to a cable sheath stripping device for power wiring. Background Technology

[0002] Cables are a general term for items such as electrical cables and wires. They have many uses, primarily for control installation, equipment connection, and power transmission, making them a common and indispensable part of daily life. All industrial production, transportation, construction projects, modern agriculture, scientific research, military equipment, space and ocean exploration, and even people's daily lives rely on cables. When laying and connecting wires during electrical construction, it is usually necessary to strip the insulation from one end of the wire to allow for conductive connection between wires or to the terminal block.

[0003] However, currently, when wiring during power construction, the outer sheath of cables is usually stripped manually using tools such as pliers or knives, exposing a section of the inner core at the cable end for subsequent connection. This method is not only inconvenient and laborious to operate, but also inefficient in stripping the cable sheath, which is not conducive to power construction. Furthermore, it is difficult to master and control, and it is easy to damage the inner core of the cable, wasting time and materials, and also easily injuring workers. The cable stripping effect is not good.

[0004] Therefore, it is necessary to provide a cable sheath stripping device for power wiring to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a cable sheath stripping device for power wiring to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cable sheath stripping device for power wiring includes a stripping sleeve and further includes:

[0008] A fixed sleeve is disposed on and rotatably connected to the peeling sleeve, used to drive the peeling sleeve to move along the cable or to restrict its lateral movement when the axis of the peeling sleeve rotates.

[0009] A limiting mechanism is provided inside the fixed sleeve, which is used to install the fixed sleeve on the cable to drive the stripping sleeve to move laterally in a stable manner or to restrict the lateral movement of the fixed sleeve when the stripping sleeve rotates.

[0010] At least one first stripping blade and a second stripping blade are provided and disposed inside the stripping sleeve. The first stripping blade is used to cut the cable along its direction, and the second stripping blade is used to perform rotational cutting along the axial direction of the cable.

[0011] An adjustment mechanism, at least one of which is provided inside the peeling sleeve, is used to simultaneously drive the first peeling knife and the second peeling knife to rise and fall, and the first peeling knife and the second peeling knife rise and fall in opposite directions.

[0012] As a further aspect of the present invention: the limiting mechanism includes a groove formed in the fixed sleeve, a limiting block is slidably connected to the inner wall of the groove, an elastic element is provided between the limiting block and the inner wall of the groove, a pressure rod is fixedly connected to the limiting block, the pressure rod movably passes through the outer wall of the fixed sleeve and a pressure plate is fixedly provided at its end.

[0013] As a further aspect of the present invention: the adjusting mechanism includes a transmission cavity opened inside the peeling sleeve, two lead screws are rotatably connected inside the transmission cavity, and sleeve rods are threadedly connected to the lead screws. The first peeling knife and the second peeling knife are respectively fixedly connected to the two sleeve rods. The transmission cavity is provided with a transmission assembly that enables the two lead screws to rotate simultaneously, and a limiting rod that movably penetrates the peeling sleeve is fixedly connected to the outer wall of the sleeve rod.

[0014] As a further aspect of the present invention: the transmission assembly includes a rotating rod rotatably connected to the transmission cavity, two worms with opposite directions of rotation fixedly connected to the rotating rod, worm wheels meshing with the two worms fixedly connected to the two lead screws respectively, and a rotating wheel fixedly connected to the end of the rotating rod.

[0015] As a further aspect of the present invention: an indicator head is fixedly connected to the limiting rod, and a vertical plate fixed to the peeling sleeve is provided on the side of the indicator head away from the limiting rod, and the vertical plate is provided with a scale on the side of the indicator head.

[0016] As a further aspect of the present invention: the inside of the fixed sleeve is provided with an annular groove, and a sliding plate is slidably connected in the annular groove, the sliding plate being fixedly connected to the peeling sleeve.

[0017] As a further aspect of the present invention: the outer wall of the peeling sleeve is fixedly connected with a plurality of handles, and the handles are provided with anti-slip sleeves.

[0018] Compared with the prior art, the advantages of this invention are:

[0019] 1. In this solution, when the first stripping blade moves downward through the adjustment mechanism, the second stripping blade moves upward. Then, the stripping sleeve and the fixing sleeve move away from the end of the cable, which will drive the first stripping blade to move along the cable. The first stripping blade will then cut the cable from the end, opening the cable sheath without damaging the inner core. This allows for the horizontal opening of the cable sheath, making the operation simple and convenient.

[0020] 2. This solution uses an adjusting mechanism to move the first stripping blade upwards away from the cable sheath, while the second stripping blade moves downwards, causing it to rotate axially and cut. At this point, the outer sheath at the cable end is peeled off, exposing the inner core. This avoids the current need for manual stripping using pliers, knives, and other tools based on feel. This device is simple and convenient to use, saving time and effort, significantly improving the efficiency of stripping the cable sheath. It is also easy to master and control the stripping process, greatly reducing the risk of damage to the inner core caused by manual operation. This saves time and materials, improves construction results, and significantly enhances the safety of workers during the stripping operation.

[0021] 3. When the sleeve rod moves up and down in this solution, it will simultaneously drive the limit rod to move up and down. The limit rod can restrict the rotation of the sleeve rod, and on the other hand, the limit rod will drive the indicator head to move. The indicator head will point to the scale on the vertical plate, so you can know the specific distance the limit rod moves up and down. This makes the cutting of the cable sheath more precise and the effect is better. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1:

[0033] Please see Figure 1-2 , Figure 4 and Figure 5-7 A cable sheath stripping device for power wiring includes a stripping sleeve 1, and further includes: a fixed sleeve 2, disposed on and rotatably connected to the stripping sleeve 1, for driving the stripping sleeve 1 to move along the cable or restricting its lateral movement when the stripping sleeve 1 rotates along its axis; a limiting mechanism 3, disposed inside the fixed sleeve 2, for mounting the fixed sleeve 2 on the cable, for driving the stripping sleeve 1 to move laterally stably or restricting the lateral movement of the fixed sleeve 2 when the stripping sleeve 1 rotates; a first stripping blade 4 and a second stripping blade 5, at least one of which is disposed inside the stripping sleeve 1, the first stripping blade 4 for cutting along the cable's direction, and the second stripping blade 5 for rotating and cutting along the cable's axial direction; and an adjusting mechanism 6, at least one of which is disposed inside the stripping sleeve 1, for simultaneously driving the first stripping blade 4 and the second stripping blade 5 to rise and fall in opposite directions.

[0034] In use, first align the fixing sleeve 2 with the end of the cable, then insert the cable end into the fixing sleeve 2. The cable is held in place by the limiting mechanism 3 within the fixing sleeve 2, allowing the fixing sleeve 2 and the stripping sleeve 1 to move stably along the cable. Before the cable is below the first stripping blade 4, the adjusting mechanism 6 moves the first stripping blade 4 downward while the second stripping blade 5 moves upward. The first stripping blade 4 gradually moves downward until the designated position. Then, move the stripping sleeve 1 and the fixing sleeve 2 away from the end of the cable, which will move the first stripping blade 4 along the cable. The first stripping blade 4 will then start cutting from the end of the cable, cutting open the cable sheath without damaging the inner core. Alternatively, when the cable is below the first stripping blade 4, the first stripping blade 4 can be lowered to cut and then cut the required distance. At this point, the transverse outer sheath of the cable can be cut open.

[0035] After the cable is cut to the designated position, the adjusting mechanism 6 moves the first stripping blade 4 upwards away from the cable sheath, while the second stripping blade 5 moves downwards to contact the cable sheath and cuts it. As it descends to the designated position, the limiting mechanism 3 applies pressure to the cable, causing the stripping sleeve 1 to rotate axially around the fixed sleeve 2 and the cable. This rotation drives the second stripping blade 5 to rotate axially, cutting the cable sheath. At this point, the cable sheath at the end is peeled off, exposing the inner core. This completes the cable sheath stripping operation. This method avoids the current need for manual stripping using pliers, knives, and other tools based on feel. The stripping operation is simple and convenient, saving time and effort, significantly improving the efficiency of cable sheath stripping. It is also easy to master and control the stripping process, greatly reducing the risk of damage to the inner core caused by manual operation. This saves time and materials, improves construction results, and significantly enhances the safety of workers during stripping operations, meeting usage requirements.

[0036] In this embodiment, preferably, please refer to [reference needed]. Figure 1 and Figure 5The limiting mechanism 3 includes a groove 31 formed within the fixed sleeve 2. A limiting block 32 is slidably connected to the inner wall of the groove 31. An elastic element 33 is provided between the limiting block 32 and the inner wall of the groove 31. A pressure rod 34 is fixedly connected to the limiting block 32. The pressure rod 34 movably passes through the outer wall of the fixed sleeve 2, and a pressure plate 35 is fixedly provided at its end. When the cable end is inserted into the fixed sleeve 2, the cable gradually squeezes the limiting block 32 within the fixed sleeve 2, causing it to move towards the groove 31 and compress the elastic element 33. The limiting block 32 slides along the cable and also exerts a clamping force on the cable, allowing the fixed sleeve 2 and the stripping sleeve 1 to move stably along the cable. Subsequently, the pressure plate 35 can be pressed down, which will exert pressure on the pressure rod 34 and the limiting block 32, and the limiting block 32 will exert pressure on the cable. At this time, the fixed sleeve 2 and the stripping sleeve 1 will not move horizontally along the cable, allowing the stripping sleeve 1 to rotate axially around the fixed sleeve 2 and the cable.

[0037] In this embodiment, preferably, please refer to [reference needed]. Figure 2 , Figure 4 and Figure 6 The adjusting mechanism 6 includes a transmission cavity 61 opened inside the peeling sleeve 1. Two lead screws 62 are rotatably connected inside the transmission cavity 61. Sleeve rods 63 are threadedly connected to the lead screws 62. The first peeling knife 4 and the second peeling knife 5 are respectively fixedly connected to the two sleeve rods 63. The transmission cavity 61 is provided with a transmission assembly 64 that makes the two lead screws 62 rotate simultaneously. A limiting rod 65 that moves through the peeling sleeve 1 is fixedly connected to the outer wall of the sleeve rod 63. The transmission assembly 64 includes a rotating rod 641 rotatably connected inside the transmission cavity 61. Two worm gears 642 with opposite directions of rotation are fixedly connected to the rotating rod 641. Worm wheels 643 that mesh with the two worm gears 642 are fixedly connected to the two lead screws 62 respectively. A rotating wheel 644 is fixedly connected to the end of the rotating rod 641. The rotating wheel 644 drives the rotating rod 641 to rotate, which in turn drives the two worm gears 642 to rotate. The worm gears 642 then drive the worm wheel 643 and the lead screw 62 to rotate, but the two lead screws 62 rotate in opposite directions. When the lead screw 62 above the first stripper 4 drives the threaded sleeve 63 to move down / up, it drives the first stripper 4 to move down / up. Similarly, the lead screw 62 above the second stripper 5 drives the threaded sleeve 63 to move up / down, which in turn drives the second stripper 5 to move up / down. When the first stripper 4 moves down, it performs a horizontal translational cut on the cable. When the second stripper 5 moves down, the rotation of the stripping sleeve 1 drives the second stripper 5 to perform an axial rotational cut on the cable, thus completing the cable stripping operation.

[0038] In this embodiment, preferably, please refer to [reference needed]. Figure 1-2 and Figure 4The fixed sleeve 2 has an annular groove inside, and a sliding plate 10 is slidably connected inside the annular groove. The sliding plate 10 is fixedly connected to the peeling sleeve 1. When the peeling sleeve 1 is rotated around the fixed sleeve 2, the peeling sleeve 1 will drive the sliding plate 10 to rotate along the annular groove, which can make the peeling sleeve 1 rotate more stably and smoothly. Multiple handles 11 are fixedly connected to the outer wall of the peeling sleeve 1. The handles 11 are equipped with anti-slip sleeves. The peeling sleeve 1 can be rotated by holding the handles 11, which facilitates manual force application and improves the rotation effect of the peeling sleeve 1.

[0039] Example 2:

[0040] Please see Figure 2-3 Based on Embodiment 1, an indicator head 7 is fixedly connected to the limiting rod 65. A vertical plate 8, fixed to the stripping sleeve 1, is located on the side of the indicator head 7 away from the limiting rod 65. A scale 9 is provided on the side of the vertical plate 8 opposite to the indicator head 7. When the lead screw 62 rotates, causing the sleeve 63 to move up and down, the sleeve 63 simultaneously causes the limiting rod 65 to move up and down. The limiting rod 65, on the one hand, restricts the rotation of the sleeve 63, ensuring its stable up and down movement; on the other hand, the movement of the limiting rod 65 causes the indicator head 7 to move, and the indicator head 7 will point to the scale 9 on the vertical plate 8. This allows the user to know the specific distance the limiting rod 65 has moved up and down, and thus the distance the sleeve 63 has moved, driving the first stripping blade 4 or the second stripping blade 5. This enables more precise cutting of the cable sheath and improves the overall performance.

[0041] Working principle: In use, first align the fixing sleeve 2 with the end of the cable, then insert the cable end into the fixing sleeve 2. The cable will gradually squeeze the limiting block 32 inside the fixing sleeve 2, causing it to move towards the slide groove 31 and compress the elastic element 33. The limiting block 32 will slide along the cable, and at the same time, the limiting block 32 will also have a clamping force on the cable. Before the cable is below the first stripping blade 4, shake the rotating wheel 644 to drive the rotating rod 641 to rotate. The rotating rod 641 will drive the two worm gears 642 to rotate, and the worm gears 642 will drive the worm wheel 643 and the lead screw 62 to rotate, but the two lead screws 62 rotate in opposite directions. At this time, the lead screw 62 above the first stripping blade 4 will drive the screw and its screw to rotate. The threaded sleeve 63 moves down, which in turn moves the first stripping blade 4 down. Meanwhile, the threaded rod 62 above the second stripping blade 5 moves the threaded sleeve 63 up, which in turn moves the second stripping blade 5 up. At this time, the first stripping blade 4 gradually moves down to the designated position. Then, the stripping sleeve 1 and the fixed sleeve 2 are moved away from the end of the cable, which will move the first stripping blade 4 along the cable. The first stripping blade 4 will then start cutting the cable from the end, cutting open the cable sheath without damaging the inner core. Alternatively, the first stripping blade 4 can be lowered and cut when the cable is below it, cutting the cable to the required distance. This will cut open the transverse outer sheath of the cable. After cutting to the designated position, reverse the rotating wheel 644. Through the above steps, it can be seen that the lead screw 62 above the first stripping blade 4 will drive the sleeve rod 63 upwards, causing the first stripping blade 4 to move upwards away from the cable sheath. Simultaneously, the lead screw 62 above the second stripping blade 5 will drive the sleeve rod 63 downwards, causing the second stripping blade 5 to move downwards. The second stripping blade 5 will gradually contact the cable sheath and cut it as it descends to the designated position. Then, press down on the pressure plate 35, which will apply pressure to the pressure rod 34 and the limiting block 32. The limiting block 32 will apply pressure to the cable. At this time, the fixing sleeve 2 and the stripping sleeve 1 will not move along the cable. Then, the stripping sleeve 1 will rotate axially around the fixing sleeve 2 and the cable, which will drive the second stripping knife 5 to rotate axially. The second stripping knife 5 will then cut the cable sheath axially. At this time, the sheath at the end of the cable will be peeled off, the cable sheath will fall off the cable and expose the inner core, thus completing the cable sheath peeling operation. After releasing the pressure plate 35, the fixing sleeve 2 and the stripping sleeve 1 can be removed from the cable.
