Description

Technical Field

[0001] This utility model relates to the field of stripping tool technology, specifically a cable sheath stripping device. Background Technology

[0002] A cable is a device for transmitting electrical energy or signals. It is usually composed of several or several groups of conductors, consisting of one or more mutually insulated conductors and an outer insulating protective layer. It is a conductor that transmits electricity or information from one place to another. During the construction of electrical systems, the preparation of cable terminations is essential.

[0003] Currently, stripping the cable sheath is the first step in cable termination. The common method involves slowly cutting the cable sheath with a utility knife, the blade pointing towards the worker's legs and hands. This can easily cause injury if the knife slips. The stripped length must be slightly longer than the cable cavity, generally 30 to 70 cm or more. However, controlling the cutting force over long distances is difficult, resulting in inconsistent cutting depths. This can easily damage the main insulation of the cable's internal core wires, and the damage is difficult to detect, potentially leading to grounding or short circuits during later operation. Therefore, we propose a cable sheath stripping device to solve these problems. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a cable sheath stripping device, which solves the problems mentioned in the background section.

[0005] (II) Technical Solution To achieve the above objectives, this utility model specifically adopts the following technical solution: A cable sheath stripping device includes a ring. A first pulley mechanism is provided on the left side wall of the ring near both the top and bottom. A first rectangular frame is fixedly embedded in the middle of the left side wall of the ring between the upper and lower first pulley mechanisms. A first driving mechanism is provided on the left side wall of the first rectangular frame. A cutting mechanism is installed on the right side of the first driving mechanism. A second rectangular frame is fixedly installed on the right side wall of the ring at a position corresponding to the first rectangular frame. A second driving mechanism is fixedly installed on the right side wall of the second rectangular frame. A second pulley mechanism is installed on the left side of the second driving mechanism.

[0006] Furthermore, the first pulley mechanism includes a mounting frame and a pulley assembly. The mounting frame is fixedly embedded in the side wall of the ring, and the side of the mounting frame facing the center of the ring has an open structure. The pulley assembly is installed between the side walls of the mounting frame.

[0007] Furthermore, the second pulley mechanism has the same structure as the first pulley mechanism, and the upper and lower sides of the second pulley mechanism are movably fitted with the upper and lower inner walls of the second rectangular frame.

[0008] Furthermore, the first driving mechanism includes a threaded sleeve, a bolt rod, and a bearing assembly. The threaded sleeve is fixedly installed on the left side wall of the rectangular frame. The bolt rod is threaded inside the threaded sleeve. The right side of the bolt rod is fixedly installed in the bearing assembly. The right side of the bearing assembly is fixedly connected to the left side of the cutting mechanism.

[0009] Furthermore, the second drive mechanism has the same structure as the first drive mechanism.

[0010] Furthermore, the cutting mechanism includes a rectangular box, a blade, and locking bolts. The rectangular box is fixedly installed on the right side of the bearing assembly. The right side of the rectangular box has an open structure. The blade is movably inserted into the right side of the rectangular box. The front and rear side walls of the rectangular box are locked and fixed to the blade by locking bolts.

Example

[0016] like Figures 1-4 As shown in the figure, an embodiment of the present invention provides a cable sheath stripping device, including a ring 1. A first pulley mechanism 2 is provided on the left side wall of the ring 1 near the upper and lower positions. A first rectangular frame 3 is fixedly embedded in the middle of the left side wall of the ring 1 between the upper and lower first pulley mechanisms 2. A first driving mechanism 4 is provided on the left side wall of the first rectangular frame 3. A cutting mechanism 5 is installed on the right side of the first driving mechanism 4. A second rectangular frame 6 is fixedly installed on the right side wall of the ring 1 at a position corresponding to the first rectangular frame 3. A second driving mechanism 7 is fixedly installed on the right side wall of the second rectangular frame 6. A second pulley mechanism 8 is installed on the left side of the second driving mechanism 7.

[0017] like Figure 2 As shown, in some embodiments, the first pulley mechanism 2 includes a mounting frame 201 and a pulley assembly 202. The mounting frame 201 is fixedly embedded in the side wall of the ring 1, and the side of the mounting frame 201 facing the center of the ring 1 has an open structure. The pulley assembly 202 is installed between the side walls of the mounting frame 201.

[0018] In this embodiment, the mounting bracket 201 is used to mount the pulley assembly 202 on the side wall of the ring 1, so that the pulley assembly 202 limits the outer surface of the cable. The outer surface of the mounting bracket 201 is a rectangular structure.

[0019] like Figure 2 As shown, in some embodiments, the second pulley mechanism 8 has the same structure as the first pulley mechanism 2, and the upper and lower sides of the second pulley mechanism 8 are movably fitted with the upper and lower inner walls of the second rectangular frame 6.

[0020] In this embodiment, the second pulley mechanism 8 can limit the right side of the cable, and the second pulley mechanism 8 can move left and right along the upper and lower side walls of the second rectangular frame 6, making the left and right movement of the second pulley mechanism 8 more stable.

[0021] like Figure 2 and Figure 3As shown, in some embodiments, the first drive mechanism 4 includes a threaded sleeve 401, a bolt rod 402, and a bearing assembly 403. The threaded sleeve 401 is fixedly installed on the left side wall of the rectangular frame. The bolt rod 402 is threaded on the threaded sleeve 401. The right side of the bolt rod 402 is fixedly installed in the bearing assembly 403. The right side of the bearing assembly 403 is fixedly connected to the left side of the cutting mechanism 5.

[0022] In this embodiment, the bolt rod 402 moves left and right spirally within the threaded sleeve 401, causing the bolt rod 402 to drive the cutting mechanism 5 to move left and right via the bearing assembly 403. The bearing assembly 403 satisfies the rotation requirements of the bolt rod 402.

[0023] like Figure 1 and Figure 2 As shown, in some embodiments, the second drive mechanism 7 has the same structure as the first drive mechanism 4.

[0024] In this embodiment, the second drive mechanism 7 can drive the second pulley mechanism 8 to move along the second rectangular frame 6.

[0025] like Figure 4 As shown, in some embodiments, the cutting mechanism 5 includes a rectangular box 501, a blade 502, and a locking bolt 503. The rectangular box 501 is fixedly installed on the right side of the bearing assembly 403. The right side of the rectangular box 501 is an open structure. The blade 502 is movably inserted into the right side of the rectangular box 501. The front and rear side walls of the rectangular box 501 are locked and fixed to the blade 502 by the locking bolt 503.

[0026] In this embodiment, the blade 502 is inserted into the rectangular box 501, and then the front and rear side walls of the rectangular box 501 are locked and fixed to the front and rear side surfaces of the blade 502 by the front and rear locking bolts 503, so that the blade 502 is installed stably and securely, and it is convenient to disassemble and replace the blade 502.

[0027] like Figure 3 As shown, in some embodiments, the upper and lower sides of the rectangular box 501 are movably fitted with the upper and lower inner walls of the first rectangular frame 3, and the front and rear sides of the rectangular box 501 are perpendicular and flush with the sides of the front and rear locking bolts 503.

[0028] In this embodiment, the upper and lower sides of the rectangular box 501 move left and right along the upper and lower inner walls of the first rectangular frame 3, so that the blade 502 in the rectangular box 501 moves left and right in a stable manner.

[0029] In use, the cable end is inserted into the ring 1. The mounting bracket 201 of the first pulley mechanism 2, which is symmetrically arranged vertically, is used to install the pulley assembly 202 on the side wall of the ring 1, so that the pulley assembly 202 limits the outer surface of the cable. The second drive mechanism 7 drives the second pulley mechanism 8 to move to the left, so that the second pulley mechanism 8 limits the right side of the cable, forming a three-point positioning. Then, according to the cable sheath, the bolt rod 402 in the first drive mechanism 4 moves left and right spirally within the threaded sleeve 401, so that the bolt rod 402 passes through the bearing assembly 40 3 drives the rectangular box 501 in the cutting mechanism 5 to move to the right, and the rectangular box 501 drives the blade 502 to move to the right, so that the blade 502 cuts into the cable sheath. Through the first pulley mechanism 2 and the second pulley mechanism 8, the ring 1 moves back and forth along the outer surface of the cable, so that the blade 502 peels off the cable sheath. This makes it less likely to scratch the operators during the peeling process of the outer sheath when making the cable head, and can control the cutting depth when peeling off the sheath. It is not easy to damage the cable core. At the same time, it can meet the peeling of cable sheaths of various specifications and has strong practicality.

[0030] In summary, this cable sheath stripping device makes it less likely to scratch workers during the outer sheath stripping process when making cable heads, and it can control the cutting depth when stripping the sheath, so as not to damage the cable core. At the same time, it can meet the requirements of stripping the sheath of various cable specifications, and has strong practicality.
