Description

Technical Field

[0001] The utility model relates to the technical field of wire stripping tools, in particular to a cable stripper. Background Art

[0002] Wire strippers, wire stripping knives and other tools are commonly used wire stripping tools when performing cable and wire wiring operations or electrical construction. However, for high-voltage cables with larger diameters and thicker insulating rubber, there are no suitable wire stripping knives or tools during wiring construction. Currently, scissors, electrician knives and other tools are mostly used to strip and cut the insulating rubber. The resulting problem is that the wire stripping speed is slow, resulting in low work efficiency.

[0003] Secondly, when conventional knives are used to strip wires, workers may easily damage the lower layer of cable insulation rubber if they are not careful. These scratches will become potential weaknesses in the insulation protection, leading to high-voltage breakdown accidents. Utility Model Content

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0039] The specific embodiment of the utility model provides a cable stripper, combined with the attached Figure 1 As shown, it mainly includes a mounting frame 1, a reverse blade set 2 and an adjustment component 5, wherein:

[0040] The mounting frame 1 is the main frame structure for mounting the reverse blade set 2 and the adjustment assembly 5;

[0041] The number of the reverse blade knife groups 2 is at least two and they are all arranged at one end of the mounting frame 1. The at least two reverse blade knife groups 2 can break at least two notches in the outer rubber of the cable, so that the outer rubber of the cable after breaking can be more easily torn off. A wire passing space 3 is formed between the at least two reverse blade knife groups 2. The wire passing space 3 is used to pass the cable. The cable to be stripped is passed from the inlet end of the wire passing space 3 and the surface rubber is broken by the reverse blade knife group 2. Then the metal cable core extends from the outlet end of the wire passing space 3. The reverse blade knife group 2 is provided with a blade 4. The blade 4 is the main blade body structure for breaking the outer rubber of the cable. The blade of the blade 4 faces the direction away from the wire passing space 3, that is, the blade is outward. Such an arrangement can make the end close to the metal core of the cable an uncut end to prevent the metal blade from damaging the metal core of the cable. In actual operation, the tip of the blade 4 extends between the outer rubber of the cable and the metal core of the cable. By pushing this cable stripper, the blade 4 can be gradually extended, thereby breaking the outer rubber of the cable.

[0042] One end of the adjustment component 5 is connected to the mounting frame 1, and the other end is connected to the reverse blade group 2. The adjustment component 5 can adjust the distance between at least two reverse blade groups 2, thereby indirectly adjusting the size of the wire passing space 3 to adapt to the use of cables of different sizes for stripping. In actual use, this cable stripper only needs to align the position of the blade 4 and push it to complete the process of breaking the outer rubber of the cable.

[0043] In one embodiment of the present application, a clamping portion 6 is provided at one end of the reverse-edge knife group 2 facing the wire passing space 3. The clamping portion 6 can be close to the metal core of the cable during the wire breaking process, thereby protecting the metal core of the cable. Specifically, a skin support head 7 is provided on the end of the clamping portion 6 close to the wire feeding direction. The thickness of the skin support head 7 gradually increases from the end facing the wire feeding direction to the end away from the wire feeding direction. The thickness of the skin support head 7 at the end facing the wire feeding direction is smaller, so that it can be more easily inserted between the outer rubber of the cable and the metal core of the cable. The skin support head 7 with increasing thickness can push the broken outer rubber of the cable when the blade 4 breaks the outer rubber of the cable, pushing the outer rubber of the cable outward. The blade 4 gradually moves away from the clamping portion 6 in the direction from the end close to the skin support head 7 to the end away from the skin support head 7. Figure 3 , 4 As shown in FIGS. 5 and 10 , the cutting edge of the blade 4 is designed to be inclined, with one end of the tip extending between the outer rubber of the cable and the metal core of the cable. During the continuous pushing process, the inclined cutting edge can break the thicker outer rubber of the cable.

[0044] In one embodiment of the present application, the reverse blade knife set 2 includes a knife seat 8, a blade 4, a knife pressing member 9 and a guide member 10. Figure 4 - Attachment Fig.10 As shown, a mounting groove 11 is provided on one side of the knife seat 8, the blade 4 is provided in the mounting groove 11, the abutting portion 6 is provided on the knife seat 8, and the abutting portion 6 is a sheet-shaped structure. Such a sheet-shaped abutting portion 6 can also play a guiding role, preventing the cable from moving out of the space between the reverse blade knife group 2 during the pushing process, thereby limiting the moving direction of the cable and ensuring that the cable can be normally stripped. The knife pressing member 9 is connected to the knife seat 8 and fixes the blade 4 on the knife seat 8, and the blade 4 is limited in the mounting groove 11. The guide member 10 is provided on the other side of the knife seat 8, and the outer side of the guide member 10 The wall surface is in a conical arc shape from the end close to the support head 7 to the end away from the support head 7. The conical arc shape is in the direction of the tip of the cone from the end close to the support head 7 to the direction of the bottom of the cone at the end away from the support head 7. In this way, the arc-shaped guide member 10 can guide the outer rubber of the cable to one side after the blade 4 breaks the outer rubber of the cable, so as to avoid the outer rubber of the cable being clamped by the blade 4. The gradual separation of the outer rubber of the cable can make it easier for the blade 4 to continue to break the outer rubber of the cable. A connecting portion 12 is provided on the knife pressing member 9, and the connecting portion 12 is used to connect with the adjustment component 5.

[0045] The knife seat 8 is made of a metal material with low hardness, or a non-metal material with good toughness, so that the abutting portion 6 has a certain elasticity to adapt to the diameter of the wire to be stripped.

[0046] In a specific embodiment of the present application, a limiting member 13 for limiting the blade 4 is provided in the mounting groove 11 of the blade 4. The limiting member 13 can be a convex block structure, and a hole of the same shape is provided on the blade 4. In this way, after the blade 4 is set in the mounting groove 11, the blade pressing member 9 can be cooperated to limit the shaking of the blade 4.

[0047] The tightening portion 6 of the present application is arc-shaped along the circumference of the wire space 3, as shown in the attached Figure 7 As shown in , the arc-shaped structure of the abutting portion 6 adapts to the outer wall of the cable, so that the abutting portions 6 on at least two reverse-edge knife groups 2 limit the moving direction of the cable, further ensuring that the cable can be stripped normally.

[0048] The number of the reverse blade groups 2 in the present application can be 2, 3, 4, 5, 6, 7, 8, etc., and the reverse blade groups 2 can be arranged in a centrally symmetrical manner.

[0049] In some embodiments, the combination Figure 1 , 3, 11, and 13, wherein the adjustment component 5 includes a movable push button 14, a telescopic rod 15, a connecting rod 16 and an articulated rod group 17, wherein the movable push button 14 is movably arranged on the mounting frame 1 along the cable threading direction; one end of the telescopic rod 15 is connected to the movable push button 14, and the other end is hinged to one end of the connecting rod 16, and the other end of the connecting rod 16 is hinged to the middle part of the articulated rod group 17; one end of the articulated rod group 17 is hinged to the mounting frame 1, and the other end is hinged to the reverse blade group 2, and the connecting part 12 can be an articulated rod arranged on the knife pressing member 9, which is used to be hinged to one end of the articulated rod group 17, so that when the movable push button 14 is adjusted, the telescopic rod 15 can be driven to move, and indirectly drive the connecting rod 16 to move, and the connecting rod 16 then drives the articulated rod group 17 to move, and finally realizes the adjustment of the reverse blade group 2.

[0050] Specifically, this articulated rod group 17 includes at least two articulated rods arranged parallel to each other, and the connecting rod 16 is hinged to one of the articulated rods. When there are two articulated rods, the two articulated rods arranged parallel to each other, the inner wall of the mounting frame 1 and the reverse blade knife group 2 form a parallelogram, so that the reverse blade knife group 2 is parallel to the inner wall of the mounting frame 1, so that the direction of the blade of the reverse blade knife group 2 remains unchanged during the adjustment process.

[0051] In some embodiments, the movable push button 14 is a sleeve structure with an internal thread, and anti-slip grooves are arranged on the outer wall. The mounting frame 1 has an external thread 18. The movable push button 14 is threadedly connected to the mounting frame 1. The movable push button 14 can be moved in a linear direction by screwing the movable push button 14. The mounting frame 1 is provided with a sliding groove 19 along the cable threading direction. The telescopic rod 15 can be slidably arranged in the sliding groove 19. A protrusion can also be arranged on the telescopic rod 15, and a long strip-shaped groove is arranged in the length direction of the sliding groove 19. The protrusion and the groove are used to limit the telescopic rod 15 to slide only along the length direction of the sliding groove 19. A limiting groove 20 is arranged on the telescopic rod 15, and the movable push button 14 is located in the limiting groove 20. This limiting groove 20 is a U-shaped groove. In this way, when the movable push button 14 rotates relative to the mounting frame 1, it can still be ensured that the movable push button 14 is in the limiting groove 20, thereby driving the telescopic rod 15 to move.

[0052] A scale is provided on the outer wall of the sliding groove 19 close to the second ring frame 22 to assist the worker in adjusting the stripping size of the cable stripper.

[0053] In some embodiments, the mounting frame 1 includes a first ring frame 21, a second ring frame 22, and a connecting foot 23. The first ring frame 21 and the second ring frame 22 are both annular cylindrical structures. The diameter of the first ring frame 21 is larger than the diameter of the second ring frame 22. One end of the connecting foot 23 is connected to the first ring frame 21, and the other end is connected to the second ring frame 22. A connecting shaft 24 is provided on the inner wall of the first ring frame 21. The articulated rod group 17 is hinged to the connecting shaft 24, and the moving push button 14 is provided on the second ring frame 22. The number of the connecting shafts 24 is the same as the number of the articulated rods of each group of articulated rod groups 17 and they are connected one by one. The layout direction of each group of connecting shafts 24 is along the moving direction of the cable.

[0054] The number of connecting pins 23 is the same as the number of reverse blade groups 2 and is arranged correspondingly, which can ensure that the connection between the first ring frame 21 and the second ring frame 22 is more stable, and that there are through holes 25 between adjacent connecting pins 23. The through holes 25 can allow the broken outer rubber of the cable to pass through.
