Description

Technical Field

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

[0002] Cables are the carriers of electrical power and a crucial component of power supply systems. Cables are typically rope-like structures made of several or more strands of conductors twisted together, with each strand insulated from the others and often twisted around a central core. The entire cable is covered with 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, the inconvenience of installation and disassembly, inaccurate cutting depth and position, the generally small blades, the difficulty of operation, and the inherent risks involved.

Detailed Implementation

[0031] like Figure 1-3In this invention, a cable quick cutting device includes two semi-ring clamps 1 arranged opposite each other. The two sides of the two semi-ring clamps 1 are connected by adjusting rods 2 and fixing rods 3 respectively. Multiple positioning rods 4 are passed through the semi-ring clamps 1. The ends of the positioning rods 4 abut against the outside of the cable 8. Adjusting nails 5 are also rotatably provided on the semi-ring clamps 1. The bottom of the adjusting nails 5 is connected to a cutting head 7 through a support seat 6. The cutting head 7 is used to cut the outer sheath of the cable 8.

[0032] When cutting thicker outer skins, in order to improve cutting efficiency, such as... Figure 4 In the process, two sets of cutting heads 7 can be set to form a relative structure. At the same time, a layer-by-layer cutting method can be adopted. After each layer is cut, the position of the support seat 6 is adjusted towards the center of the cable 8, so that the cutting head 7 can penetrate deeper into the outer sheath. This ensures the cutting effect while avoiding damage to the cutting head 7 and extending the service life.

[0033] Since different cables 8 have different specifications and diameters, the cable 8 can be easily fixed by setting two semi-ring clamps 1. At the same time, positioning rods 4 are used for quick positioning. Multiple positioning rods 4 at different positions maintain the same installation length, which ensures that the two semi-ring clamps 1 and the cable 8 remain coaxial, thus ensuring the cutting effect of the cutter head 7. The rotating adjustment pin 5 can change the position of the support base 6 relative to the cable 8, thereby changing the position of the cutter head 7. It is convenient to use and the cutting is fast.

[0034] like Figure 8-9 The middle section describes the initial installation process of this device. By adjusting the angle of the upper semi-ring clamp 1 and operating the adjusting rod 2, sufficient distance is maintained between the two semi-ring clamps 1 to form an opening. After directly positioning it to the cutting position, the upper semi-ring clamp 1 is realigned with the lower semi-ring clamp 1 and then locked. This avoids the relatively troublesome situation when the cutting point is far from the end face of the cable 8, as the fully enclosed structure makes it impossible to adjust the angle of the semi-ring stirring 1. Figure 5-7 In the middle part, during the process of cutting cable 8, the initial insertion depth of the cutter head 7 relative to cable 8 is adjusted. Then, the entire device is rotated, and the cutter head 7 will cut the outer sheath around the axis of cable 8. After cutting to the designed depth, the outer sheath can be completely removed, thereby exposing the conductor of the cable core, which is convenient for subsequent installation and construction.

[0035] like Figure 10-13 In the preferred embodiment, the semi-annular clamp 1 includes an arc plate 101, with ear plates 102 on both sides of the arc plate 101. The ear plates 102 on both sides are respectively provided with a first threaded hole 103 and a through groove 107. A third through hole 108 is also provided in the through groove 107. The adjusting rod 2 is threadedly connected to the first threaded hole 103 on the upper side, and the fixing rod 3 is hinged to the through groove 107 on the lower side.

[0036] The ear plate 102 ensures that the adjusting rod 2 and the fixing rod 3 are fully fixed and have a good locking effect. It also allows for adjustment of the position and angle of any half-ring clamp 1 as needed, ensuring ease of use.

[0037] In a preferred embodiment, the adjusting rod 2 includes a threaded portion 201, and optical shaft portions 202 are respectively provided on both sides of the threaded portion 201. A fourth through hole 203 is provided through the optical shaft portion 202. A positioning plate 204 is also provided on the lower optical shaft portion 202. The positioning plate 204 abuts against the top of the lower ear plate 102. The lower optical shaft portion 202 is connected to the ear plate 102 by a locking pin 205.

[0038] The lower optical shaft portion 202 of the adjusting rod 2 passes through the first threaded hole 103, and locks the ear plate 102 through the cooperation of the locking pin 205 and the positioning plate 204. At this time, the adjusting rod 2 can rotate on the lower half-ring clamping plate 1, while the upper half-ring clamping plate 1 can move relative to each other under the constraint of the fixing rod 3 when the adjusting rod 2 is rotated, thereby changing the clamping space and satisfying the change of the outer diameter of the cable 8 within a certain range.

[0039] In a preferred embodiment, the upper optical axis portion 202 is connected to a locking cap 206 via a locking pin 205, and the threaded portion 201 and the first threaded hole 103 located on the upper side have the same thread direction.

[0040] The addition of a locking cap 206 improves the ease of operation for staff, ensures stability and speed when rotating the adjusting rod 2, and prevents slippage.

[0041] In a preferred embodiment, the fixing rod 3 includes a first rod body 301, with a fifth through hole 302 extending through the lower side of the first rod body 301. The insertion rod 305 passes through the fifth through hole 302 and the third through hole 108. The first rod body 301 is fixed by a wing nut 303, a connecting ring 304, and an ear plate 102. The wing nut 303 and the connecting ring 304 are threadedly connected to the first rod body 301, respectively.

[0042] The lower part of the fixing rod 3 is hinged to the lower half-ring clamp 1 via the insertion rod 305, which allows for easy locking or unlocking of the upper half-ring clamp 1. After the device is installed on the cable 8, the fixing rod 3 needs to be fixed to the upper half-ring clamp 1. Then, the adjusting rod 2 is rotated to adjust the distance between the two half-ring clamps 1 to the outer diameter of the cable 8. Finally, the positioning rods 4 at different positions are rotated to complete the overall locking.

[0043] In a preferred embodiment, the wing nut 303 and the connecting ring 304 abut against the upper and lower sides of the ear plate 102, respectively, and the outer side of the connecting ring 304 is provided with a plurality of friction grooves 306 along the circumferential direction.

[0044] The wing nut 303 and the connecting ring 304 abut against the two sides of the ear plate 102 respectively, thus ensuring stable operation when the adjusting rod 2 fails. This serves as a foolproof safety design with good performance. The outer diameter of the connecting ring 304 is not less than the width of the ear plate 102.

[0045] In a preferred embodiment, the arc plate 101 has second threaded holes 104 through both sides. The positioning rod 4 includes a second rod body 401. The two sides of the second rod body 401 are respectively provided with a rotating head 402 and a ball bearing 403. The ball bearing 403 and the second rod body 401 are connected by a ball joint. The second rod body 401 passes through the second threaded holes 104. The ball bearing 403 abuts against the outer wall of the cable 8. The arc plate 101 is also provided with a vertical plate 109. The vertical plate 109 has multiple scale lines 110 on the side near the positioning rod 4.

[0046] By checking the position of the rotating head 402 of the positioning rod 4 at different positions and corresponding to the scale line 110 on the corresponding vertical plate 109, when all are adjusted to the same scale line 110, the whole is locked. Then, the cutter head 7 is inserted into the outer sheath of the cable 8, and a pushing force is applied from the side of the vertical plate 109 relative to the scale line 110. At this time, the whole device will cut the outer sheath of the cable 8 with the cutter head 7. The layer-by-layer cutting method can be adopted according to the needs of use, so as to ensure the cutting effect, improve the cutting stability, and reduce the wear of the cutter head 7.

[0047] When the side of the upright plate 109 is rotated, the ball bearing 403 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.

[0048] In a preferred embodiment, the top of the arc plate 101 is provided with a first through hole 105, and the two sides of the first through hole 105 are provided with second through holes 106. The adjusting pin 5 is rotatably inserted into the first through hole 105. The support base 6 includes a base plate 601, the top of the base plate 601 is provided with a threaded sleeve 602, and the two sides of the threaded sleeve 602 are provided with guide rods 603. The adjusting pin 5 and the threaded sleeve 602 are threadedly connected, and the guide rods 603 are inserted into the second through holes 106.

[0049] By rotating the adjusting pin 5, the threaded sleeve 602 will move in the opposite direction along the axis due to the limiting position of the guide rod 603. This allows the cutter head 7 to move closer to or further away from the outer sheath of the cable 8, following the position of the support seat 6, making operation convenient.

[0050] In a preferred embodiment, the adjusting pin 5 includes a knob 501, with an annular groove 502 on one side of the knob 501. The adjusting pin 5 is connected to the arc plate 101 via a retaining spring 9, and the retaining spring 9 is fitted inside the annular groove 502.

[0051] The retaining ring 9 can reliably ensure that the adjusting pin 5 works in the first through hole 105, preventing it from coming off. At the same time, the length of the annular groove 502 and the thickness of the arc plate 101 and the thickness of the retaining ring 9 are matched, resulting in a good overall locking effect. The adjusting pin 5 rotates smoothly and flexibly, avoiding the problem of jamming.

[0052] In a preferred embodiment, the top of the cutter head 7 is provided with an adapter plate 11, which is inserted into the base plate 601. The outer side of the cutter head 7 is also provided with a detachable protective cover 10, which includes a cover plate 1002. A slot 1001 is provided on one side of the cover plate 1002, and the base plate 601 is engaged with the slot 1001. The inner side of the cover plate 1002 abuts against the bottom of the cutter head 7.

[0053] After cutting is completed, the cutter head 7 needs to be protected to prevent damage from bumps and collisions, and also to prevent injury to the operator. It adopts a snap-fit ​​design, which is easy to install and remove. Different cutter heads 7 can also be replaced according to the needs of use. The cutter head 7 is fixed on the adapter plate 11, which improves overall safety and makes it more flexible to use. The bottom of the base plate 601 is provided with a slot corresponding to the adapter plate 11.

[0054] 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.
