Description

Technical Field

[0001] This utility model relates to the field of cable tool technology, and in particular to a device for stable cutting of cable sheaths. Background Technology

[0002] Cables are the carriers of electrical power and a crucial component of power supply systems. Cables are typically rope-like structures composed of several or groups of conductors twisted together, with each group of conductors insulated from the others, often twisted around a central core, and covered by a highly insulating outer layer. During electrical installations, because cable lengths are often not optimal, they need to be cut and stripped to expose the internal cable cores (conductors) before subsequent connections and installations. However, manual operation presents challenges due to the complexity of the cutting equipment, inconvenient installation and disassembly, inaccurate cutting depth and position, unstable cutting process, and inherent construction risks.

Detailed Implementation

[0031] like Figure 1-3 In the present invention, a device for stable cutting of cable sheath includes two fixed plates 2 arranged opposite to each other. The two sides of the two fixed plates 2 are connected by locking components 3 respectively. The two fixed plates 2 are connected by locking components 3 to form a clamping opening. The cable 1 is inserted into the clamping opening. Positioning components 4 are telescopically provided on both sides of the fixed plates 2. Two rollers 5 are symmetrically provided at the bottom of the positioning components 4. An adjustment frame 6 is provided in the middle of the two positioning components 4. A cutting head 7 for cutting the cable 1 is provided at the bottom of the adjustment frame 6.

[0032] Since different cables 8 have different specifications and diameters, the cables 8 can be easily fixed by setting two fixing plates 2. At the same time, the positioning component 4 can be used for quick positioning. Multiple rollers 5 at different positions maintain the same installation length, which can ensure that the two fixing plates 2 and the cables 8 are coaxial, thus ensuring the cutting effect of the cutter head 7. Changing the position of the adjusting frame 6 changes the position of the cutter head 7, which is convenient to use and allows for fast cutting.

[0033] like Figure 4-7 In this solution, which is a flowchart of the cutting process, after the fixing plate 2 is installed on the cable 8, the adjusting frame 6 changes position accordingly, so that the cutting head 7 is inserted into the outer sheath of the cable 8. Then, the two fixing plates 2 are rotated as a whole to complete the cutting. After the cutting is completed, the cut outer sheath is removed, which is convenient to use.

[0034] like Figure 8 In the preferred embodiment, the fixing plate 2 includes two ear plates 202 arranged opposite to each other. The inner side of the ear plate 202 is provided with an arc plate 201. The two opposite arc plates 201 are connected by a C-shaped plate 203. The adjustment frame 6 is arranged inside the C-shaped plate 203. The two ear plates 202 are connected by a locking component 3. The positioning component 4 is arranged on the arc plate 201.

[0035] The C-shaped plate 203 serves as a clearance area. When the device is not in use, the cutter head 7 can be completely retracted into the C-shaped plate 203 to avoid collisions and damage to the cutter head 7, making the whole device safer. At the same time, the two ear plates 202 can be quickly aligned and connected through the locking component 3. This device has good versatility and high interchangeability, and the overall manufacturing is more convenient and the operating cost is lower.

[0036] like Figure 9-10 In the preferred embodiment of 12-13, a through groove 204 is provided through the ear plate 202, and a first through hole 205 is provided through the through groove 204. The locking assembly 3 includes a straight rod 301, and a fourth through hole 305 is provided at the bottom of the straight rod 301. The insert rod 304 passes through the first through hole 205 and the fourth through hole 305. A wing nut 302 and a locking ring 303 are threadedly connected to the top of the straight rod 301.

[0037] Adjust the relative positions of the wing nut 302 and the locking ring 303, rotate the straight rod 301 around the axis of the insertion rod 304, align it with the through groove 204, and after it is engaged, adjust the positions of the wing nut 302 and the locking ring 303 again, and lock and fix the ear plate 202 from the upper and lower sides respectively. The outer side of the locking ring 303 is also provided with multiple friction grooves along the circumference to ensure stability during rotation. The outer diameter of the locking ring 303 is not less than the width of the ear plate 202.

[0038] like Figure 11 In the preferred embodiment, the C-shaped plate 203 has a first threaded hole 206 through the middle, the adjustment frame 6 includes a support rod 601 and a base 603, the support rod 601 passes through the first threaded hole 206, the lower side of the support rod 601 is rotatably mounted on the base 603, and the cutter head 7 is mounted at the bottom of the base 603.

[0039] By rotating the support rod 601, the height of the base 603 can be changed, thereby changing the position of the cutter head 7 relative to the cable 8. When the support rod 601 rotates, it will not cause the base 603 to rotate, thus avoiding changes in the cutting angle of the cutter head 7. The cutter head 7 is directly facing the cross-section of the cable 8, making the overall cutting smoother.

[0040] In the preferred embodiment, the first threaded hole 206 is provided with second through holes 207 on both sides, the base 603 is provided with a sliding groove 604 on the top, the support rod 601 is located in the sliding groove 604 on the lower side, the base 603 is provided with a guide rod 606 on the top, the guide rod 606 passes through the second through hole 207, the support rod 601 is detachably inserted with a rotating rod 10 on the top, and the number of cutter heads 7 is two.

[0041] The length of the support rod 601 is greater than the length of the guide rod 606, which ensures convenient operation and sufficient rotation space after the rotating rod 10 is installed. At the same time, the guide rod 606 can prevent the position of the support rod 601 from changing during the rotation of the support rod 601. At this time, the guide rod 606 restricts the angle of the base 603, converting the circular motion into linear motion, resulting in high movement accuracy and good effect.

[0042] In a preferred embodiment, two third threaded holes 605 are symmetrically provided on the inner side of the slide groove 604, and a disc 602 is provided at the bottom of the support rod 601. The disc 602 abuts against the slide groove 604. The slide groove 604 has a T-shaped cross section. A screw 9 is provided in the third threaded hole 605, and the screw 9 is pressed on the top of the disc 602.

[0043] The outer diameter of the disc 602 is larger than the outer diameter of the support rod 601. The disc 602 and the support rod 601 are slidably installed in the slide groove 604. After being locked on both sides by the screws 9, they can only rotate in the middle of the base 603, and the rotation is smooth and stable.

[0044] In a preferred embodiment, an L-shaped plate 208 is provided on the upper side of the ear plate 202, a third through hole 209 is provided through the top of the L-shaped plate 208, a square hole 212 is provided through the ear plate 202, the positioning component 4 includes a square sleeve 401 and a threaded rod 402, a second threaded hole 403 is provided through the threaded rod 402, the square sleeve 401 and the threaded rod 402 are threadedly connected, the square sleeve 401 and the square hole 212 are slidably connected, and the square sleeve 401 can be rotatably inserted into the third through hole 209.

[0045] The L-shaped plate 208 serves as the mounting platform for the positioning component 4, ensuring convenient and stable movement of the positioning component 4. The design of the square sleeve 401 and square hole 212 ensures that the square sleeve 402 will not rotate around its own axis during the rotation of the threaded rod 402. Three sides of the square sleeve 401 abut against the square hole 212, which has a rectangular cross-section with a width equal to the side length of the square sleeve 401. By rotating the threaded rod 402, its position remains unchanged. At this time, the square sleeve 401 adjusts its height under traction, thereby changing the position of the roller 5.

[0046] In a preferred embodiment, a protruding plate 404 is provided on one side of the bottom of the threaded rod 402, and a shaft 405 is provided on both sides of the protruding plate 404. The roller 5 is sleeved on the shaft 405, and an annular groove 406 is provided on the top of the threaded rod 402. The retaining spring 8 is sleeved in the annular groove 406.

[0047] The length of the square hole 212 is not less than the sum of the lengths of the square sleeve 401 and the protruding plate 404, thus ensuring that the roller 5 can also pass through the square hole 212, completing the overall avoidance and ensuring strong adaptability to the outer diameter of the cable 8. The roller 5 is rotatably sleeved on the shaft 405. When the side of the L-shaped plate 208 is pushed to rotate, the roller 5 can rotate around the surface of the cable 8. Since the outer sheath of the cable 8 is generally made of rubber, the overall frictional resistance is reduced, resulting in good performance. The symmetrically arranged two rollers 5 also ensure that the rotation process is smooth and flexible, and there will be no problem of tilting to one side.

[0048] In the preferred embodiment, the top of the threaded rod 402 is connected to a push plate 408 via a cover plate 407, and the two sides of the snap ring 8 abut against the side wall of the annular groove 406 and the bottom surface of the L-shaped plate 208, respectively.

[0049] By setting the push plate 408, the threaded rod 402 can be rotated flexibly, thus ensuring convenient and stable operation.

[0050] In a preferred embodiment, the upper and lower sides of the L-shaped plate 208 are provided with diagonal bracing plates 211, and the inner side of the L-shaped plate 208 is provided with scale lines 210.

[0051] In order to precisely adjust the rollers 5 at different positions and ensure the coaxiality of the whole device and the cable 8, so as to ensure the accuracy of the outer sheath cutting during the process of the whole device cutting the outer sheath, the position of the square sleeve 401 at different positions can be directly viewed through the scale line 210. When there is a difference, fine adjustment can be made. The operation is simple and effective.

[0052] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
