Description

Technical Field

[0001] This utility model relates to the field of cable construction tools, and in particular to a cable cutting device that is easy to use. 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 inaccuracies in cutting depth and location, and the generally small blades used make the process difficult and risky.

[0003] Chinese patent document CN 108347017 A describes a cable stripping device, which is mainly for long-distance cutting and is large in size, making it inconvenient to carry. Chinese patent document CN 212412634 U describes an automated wiring device for power construction, which also has the above problems and its use is defective, requiring improvement.

Detailed Implementation

[0030] like Figure 1-4In this invention, a user-friendly cable cutting device includes a retainer 2 sleeved on the outside of a cable 1. The retainer 2 is abutted against the cable 1 by a locking pin 3. A support frame 4 is rotatably mounted on the retainer 2. An adjustment component 5 is mounted on the support frame 4. The adjustment component 5 includes a straight plate 505. A blade 6 for cutting the cable 1 is mounted at the bottom of the straight plate 505. The straight plate 505 can move radially along the retainer 2. The contact state between the blade 6 and the cable 1 can be changed by adjusting the position of the straight plate 505.

[0031] During power construction, cable 1 needs to be stripped as needed. A common method is cutting it using patent CN 104051987 A, but this cutting process is inaccurate and can damage the internal conductors of cable 1. The retainer 2 is fixed to the outside of cable 1 using locking pins 3. Since the cross-sectional roundness of cable 1 is generally good, the retainer 2 can be adjusted to be coaxial with the cut point of cable 1 by adjusting the position of the locking pins 3. Figure 5-7 Then, change the position of the straight plate 505 on the adjustment component 5, insert the blade 6 into the cable 1 to the designed position, and finally rotate the support frame 4 in the opposite direction. The blade 6 cuts the outer sheath of the cable 1 along the circumference to complete the overall stripping and removal.

[0032] like Figure 8-9 In the preferred embodiment, the retainer 2 includes a ring 204, which has a plurality of first threaded holes 201 along its circumference. The locking pin 3 passes through the first threaded holes 201. A step 202 is provided on one side of the ring 204. The support frame 4 includes a slip ring 401, which is sleeved on the step 202. The support frame 4 is connected to the retainer 2 through a first fixing ring 7.

[0033] In the initial state, tighten the first fixing ring 7 to firmly lock the support frame 4 against the step 202 of the ring 204. By synchronously adjusting the positions of the locking pins 3 at different positions, fix the retainer 2 on the ring 204. After the retainer 2 is installed in place, loosen the first fixing ring 7. The support frame 4 can then rotate around the circumference of the cable 1. The operation is convenient and the effect is good.

[0034] In the preferred embodiment, the locking pin 3 is provided with a round head 301 and a first gripping head 302 on both sides respectively. The round head 301 abuts against the outer wall of the cable 1. A marking plate 203 is also provided on one side of the first threaded hole 201. The marking plate 203 is provided with multiple scale lines 205.

[0035] The round head 301 abuts against the outside of the cable 1, and the installation process will not cause wear or damage to the outer sheath of the cable 1, ensuring the integrity of the outer sheath of the uncut part of the cable 1 and good safety. The marking plate 203 is used to check whether the installation length of the locking pins 3 at different positions is the same during operation, so as to facilitate the adjustment of the retainer 2 to keep it in a coaxial state with the cable 1.

[0036] In the preferred embodiment, the first fixing ring 7 and the step 202 are threadedly connected, the two sides of the slip ring 401 are attached to the step 202, and a retaining ring 10 is provided on the outer side of the first fixing ring 7.

[0037] By adjusting the position of the first fixing ring 7, the relative state between the slip ring 401 and the retainer 2 is changed. When not in use, tightening the first fixing ring 7 ensures that the whole structure does not shake, making it safe to use and easy to store. When needed, loosening the first fixing ring 7 allows the slip ring 401 to rotate along the cable 1 as needed, thereby driving the blade 6 to cut the outer sheath of the cable 1.

[0038] like Figure 10-12 In the preferred embodiment, the slip ring 401 is provided with an L-shaped plate 402, and the adjustment assembly 5 includes a base 501 and an adjustment pin 506. The adjustment pin 506 is rotatably mounted on the slip ring 401. A fixing sleeve 502 is provided in the middle of the base 501. The adjustment pin 506 and the fixing sleeve 502 are threadedly connected. A guide rod 503 is provided on the outside of the fixing sleeve 502.

[0039] L-shaped plate 402 provides adjustment space and range of movement for adjustment component 5. The height of base 501 is adjusted by adjusting pin 506, thereby changing the distance between the bottom of blade 6 and the outer sheath of cable 1. When installing retainer 2, base 501 needs to be adjusted to the highest position to avoid the risk of blade damage or breakage caused by collision with blade 6 when it is sleeved on cable 1. After fixing retainer 2, adjust blade 6 downwards until the outer sheath can be completely cut off.

[0040] In the preferred embodiment, the bottom of the base 501 is provided with a sliding groove 504, the straight plate 505 is inserted into the sliding groove 504, and the number of guide rods 503 is two.

[0041] The guide rod 503 ensures that the base 501 and the L-shaped plate 402 are in relatively accurate positions during the rotation of the adjusting pin 506, and that they only move in the axial direction without rotation. The straight plate 505 clamps the blade 6, and different blades 6 can be used as needed to adapt to different cutting scenarios.

[0042] In a preferred embodiment, a first through hole 403 is provided through the middle of the slip ring 401, and second through holes 404 are provided through both sides of the first through hole 403. The adjusting pin 506 and the guide rod 503 are respectively inserted into the first through hole 403 and the second through hole 404.

[0043] Easy to install and quick to adjust. The distance between the guide rod 503 and the adjusting pin 506 should be greater than the width of the minimum operating space for the operator wearing gloves.

[0044] In a preferred embodiment, a second gripping head 507 is provided on one side of the adjusting pin 506, and an annular groove 508 is provided on the side near the second gripping head 507. The adjusting pin 506 is connected to the slip ring 401 via a retaining spring 9, and the retaining spring 9 is fitted into the annular groove 508.

[0045] By setting the retaining ring 9, it is ensured that the adjusting pin 506 can only rotate circumferentially and will not have axial movement. The whole is firmly fixed and has high locking accuracy. The two sides of the retaining ring 9 are respectively attached to the inner side of the annular groove 508 and the bottom of the L-shaped plate 402, making installation and removal convenient.

[0046] In a preferred embodiment, the outer side of the slip ring 401 is detachably equipped with a pull ring assembly 8. By applying force to the pull ring assembly 8, it is easy to quickly pull the pull ring assembly 8, which carries the blade 6, to cut the outer sheath of the cable 1 circumferentially.

[0047] In a preferred embodiment, the slip ring 401 is provided with reinforcing plates 405 on both sides, and the reinforcing plates 405 are provided with second threaded holes 406. The pull ring assembly 8 includes a second fixing ring 801 and a connecting rod 802, and the connecting rod 802 is threadedly connected to the second threaded hole 406.

[0048] The reinforcing plate 405 ensures the structural stability of the L-shaped plate 402 and makes the overall rigidity stronger. At the same time, the position of the connecting rod 802 can be adjusted as needed, making it convenient for workers to apply force to the second fixing ring 801.

[0049] 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.
