Description

Technical Field

[0001] This utility model relates to the technical field of cable stripping tools, specifically a cable stripping knife with a protective structure. Background Technology

[0002] Wires and cables are wire products whose core function is to transmit electrical (magnetic) energy, information, or to convert electromagnetic energy. In a broad sense, all conductors can be called cables; in a narrow sense, cables specifically refer to insulated cables composed of one or more insulated cores and their sheathing, protective layers, etc.

[0003] After the cables are manufactured, in order to ensure that the cables meet the quality standards, it is often necessary to take a section of the cable for random inspection, cut it open and strip the insulation to understand the condition of the internal wire core.

[0004] In existing technologies, to avoid wasting cables, only a certain length of cable is often cut for stripping. For the cut cable, workers often use a utility knife or blade to strip the insulation on a workbench. If improper or unstable manual operation occurs when using a utility knife or blade, the direction of the utility knife or blade on the cable may deviate. After the direction of the utility knife or blade deviates, it may scratch the workbench and require secondary stripping of the cable. On the other hand, it may also scratch the worker's hand, increasing the probability of workplace injury.

[0005] Therefore, in order to better perform cable stripping, we designed a cable stripper with a protective structure. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cable stripper with a protective structure, comprising a protective frame and a stripper body, wherein the stripper body includes a limiting plate and a stripping blade; the protective frame has a cable placement groove inside, and adjustment grooves are provided on both sides of the inner wall of the cable placement groove, wherein a limiting plate is movably connected in the adjustment groove, and an installation groove is provided on the inner top wall of the cable placement groove, wherein limiting slots are provided at equal intervals on the left and right sides of the inner wall of the installation groove; the limiting plate is inserted into the limiting slot, and a locking screw for fastening the limiting plate is threadedly connected to the top center of the protective frame.

[0008] As a further embodiment of this utility model: the peeling blade is fixed at the bottom center of the limiting plate, the peeling blade is placed in the wire placement groove, and the multiple limiting slots on the left and right sides of the inner wall of the mounting groove are grouped in pairs, and the two sides of the limiting plate are respectively placed in two limiting slots belonging to the same group on the inner wall of the mounting groove.

[0009] As a further embodiment of this utility model: the top of the limiting plate is provided with a positioning groove, the bottom of the locking screw is placed in the mounting groove and a positioning block is fixed thereon, the size of the positioning block is adapted to the size of the positioning groove, and the positioning block is threadedly connected in the positioning groove.

[0010] As a further embodiment of this utility model: a limiting rod is fixed at each of the four corners on one side of the limiting plate, and the end of the limiting rod away from the limiting plate moves through the limiting hole opened inside the protective frame. An adjusting screw is threadedly connected to the middle of the left and right sides of the protective frame, and one end of the adjusting screw is threaded through the adjusting groove and rotatedly connected to the limiting plate.

[0011] As a further embodiment of this utility model: the bottom of the limiting plate and the bottom of the protective frame are on the same horizontal line.

[0012] As a further embodiment of this utility model, the blade at the bottom of the peeling blade is designed to be inclined.

[0013] As a further embodiment of this utility model: grooves are provided at the bottom of both sides of the protective frame, and rotating rollers are rotatably connected at equal distances in the grooves. The bottom of the rotating rollers and the bottom of the limiting plate are located on the same horizontal line.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] I. In this application, through the designed protective frame, stripper body, locking screw, and limiting plate, the cable to be stripped can be effectively placed in the cable tray on the workbench. The operator only needs to slide the protective frame to drive the stripper body to open and strip the cable. This method allows the opening and stripping operation of the cable to be completed quickly, with higher efficiency and simpler operation. It also makes the stripped opening straight, which is convenient for subsequent stripping. Since the stripper body is located inside the protective frame, it can effectively avoid contact with the operator's hands, thereby avoiding scratches to the operator and improving safety. It also prevents the blade from contacting the workbench and scratching the workbench.

[0016] Second, in this application, by designing multiple limiting slots and adjusting screws, the height of the stripper body within the protective frame can be adjusted, and the distance between the two limiting plates can be adjusted, so that the stripper can strip cables of different diameters, making it more versatile and able to meet the needs of enterprises when producing cables of different diameters.

[0017] Third, in this application, by unlocking the locking screw, the peeling knife body can be easily removed from the protective frame, thereby achieving the purpose of maintaining or replacing the peeling knife body and facilitating subsequent continuous use. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] Please see Figure 1-7In this embodiment, a cable stripper with a protective structure includes a protective frame 1 and a stripper body 2. The stripper body 2 includes a limiting plate 201 and a stripping blade 202. The protective frame 1 has a cable placement groove 3 inside, and adjustment grooves 4 are provided on both sides of the inner wall of the cable placement groove 3. A limiting plate 5 is movably connected in the adjustment groove 4. The bottom of the limiting plate 5 is at the same horizontal line as the bottom of the protective frame 1. The limiting plate 5 can move in the adjustment groove 4. When stripping the cable, the bottom of the protective frame 1 and the bottom of the limiting plate 5 are simultaneously attached to the workbench to ensure stability. An installation groove 6 is provided on the inner top wall of the cable placement groove 3. Limiting slots 7 are provided at equal distances on the left and right sides of the inner wall of the installation groove 6. The limiting plate 201 is inserted into the limiting slot 7. A locking screw 8 for fastening the limiting plate 201 is threadedly connected to the center of the top of the protective frame 1.

[0031] Please see Figure 1 , Figure 3 , Figure 5 and Figure 7 Furthermore, the peeling blade 202 is fixed at the bottom center of the limiting plate 201. The peeling blade 202 is placed in the wire groove 3. The blade edge at the bottom of the peeling blade 202 is designed to be inclined. The multiple limiting grooves 7 on the left and right sides of the inner wall of the mounting groove 6 are in pairs, and the two sides of the limiting plate 201 are respectively placed in the two limiting grooves 7 belonging to the same group on the inner wall of the mounting groove 6.

[0032] Specifically, the bottom of the stripping blade 202 is an inclined blade, which makes it easy to open and strip the cable. The limiting plate 201 is inserted into the limiting slot 7, which can be used to limit and guide the limiting plate 201 to ensure the position accuracy of the stripping blade 202.

[0033] Please see Figure 1 , Figure 2 and Figure 5 Furthermore, the top of the limiting plate 201 is provided with a positioning groove 10, the bottom of the locking screw 8 is placed in the mounting groove 6 and a positioning block 801 is fixed thereon. The size of the positioning block 801 is adapted to the size of the positioning groove 10, and the positioning block 801 is threadedly connected in the positioning groove 10.

[0034] Specifically, the top of the limiting plate 201 has a positioning groove 10, and the bottom of the locking screw 8 has a positioning block 801. On the one hand, the connection between the positioning block 801 and the positioning groove 10 can be used to press the limiting plate 201 into the limiting groove 7. On the other hand, the verticality of the locking screw 8 can be used to fix the position of the limiting plate 201, so as to prevent the limiting plate 201 from shifting in the limiting groove 7.

[0035] Please see Figure 1 , Figure 4 and Figure 5Furthermore, limit rods 501 are fixed at the four corners of one side of the limit plate 5. The end of the limit rod 501 away from the limit plate 5 is movably inserted into the limit hole opened inside the protective frame 1. Adjusting screws 9 are threadedly connected to the middle of the left and right sides of the protective frame 1. One end of the adjusting screw 9 is threaded through the adjusting groove 4 and is rotatably connected to the limit plate 5.

[0036] Specifically, by turning the adjusting screw 9, the staff can move the limiting plate 5, thereby adjusting the distance between the two limiting plates 5, which is convenient for limiting cables of different diameters. When the limiting plate 5 moves, it can also be limited by the limiting rod 501 to ensure that the limiting plate 5 moves horizontally.

[0037] Example 2:

[0038] Please see Figure 8 In this embodiment, grooves 11 are provided at the bottom of both sides of the protective frame 1. Rotating rollers 12 are rotatably connected at equal distances in the grooves 11. The bottom of the rotating rollers 12 and the bottom of the limiting plate 5 are on the same horizontal line.

[0039] Specifically, for different work platforms, if sliding friction is not suitable for opening and peeling, a rotating roller 12 can be installed at the bottom of the protective frame 1. That is, when in use, the bottom of the protective frame 1 can be rotated by the rotating roller 12 and move on the worktable in the form of rolling friction, so that the staff can choose different solutions for different work platforms.

[0040] When using the cable, the worker places a section of cable that has been cut off on the workbench, and then attaches the protective frame 1 to the cable. The top of the cable is in contact with the bottom edge of the stripping blade 202, and the two sides of the cable are respectively attached to the two limiting plates 5. The two limiting plates 5 limit the two sides of the cable, so that the cable inside the protective frame 1 is in a straight state. Finally, the worker only needs to press down the beginning of the cable with one hand and press down the protective frame 1 with the other hand, and slide the protective frame 1 on the workbench. When the protective frame 1 slides, it drives the stripping blade 202 to open on the cable until the protective frame 1 slides out from the end of the cable, thus completing the opening and stripping of the cable.

[0041] When stripping cables of different diameters, the operator only needs to loosen the locking screw 8 and remove the positioning block 801 at the bottom of the locking screw 8 from the positioning groove 10. Then, the stripper body 2 is pulled out from the limiting slot 7, and the stripper body 2 is inserted into the limiting slot 7 at different heights using the limiting plate 201. After insertion, the locking screw 8 is tightened again, so that the positioning block 801 at the bottom of the locking screw 8 enters the positioning groove 10, applying a fastening force to the limiting plate 201, thereby ensuring the stability of the stripper body 2 during operation. In other words, when the limiting plate 201 is placed in the limiting slot 7 at a higher position, it can limit cables with larger diameters; when the limiting plate 201 is placed in the limiting slot 7 at a lower position, it can limit cables with smaller diameters.

[0042] Then, turn the two adjusting screws 9 respectively. The rotation of the adjusting screws 9 will drive the limiting plate 5 to move, so that the two limiting plates 5 can move closer to each other or further apart. When the two limiting plates 5 are closer to each other, they can limit the cables with smaller diameters. When the two limiting plates 5 are further apart, they can limit the cables with larger diameters. Finally, by adjusting the height of the stripper body 2 and the diameter distance between the two limiting plates 5, the opening stripping operation of cables of different diameters can be realized.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
