Description

Technical Field

[0001] This utility model relates to the stripping of cable outer sheath and cable core insulation layer in the field of cables, and in particular to a portable cable stripping device. Background Technology

[0002] Cable wiring is an important construction procedure in the field of electrical equipment assembly in engineering. According to the electrical equipment construction procedure, before wiring, the outer sheath and the insulation layer of the cable core wires must be stripped. These are collectively referred to as cable sheaths below. After the cable sheaths are stripped, the exposed cable metal core wires are then wired.

[0003] In engineering practice, the removal of the outer sheath and insulation layers of cables is usually done using general-purpose tools such as diagonal pliers and electrician's knives. The specific procedure is to straighten the cable, hold the electrician's knife, and use the tip of the knife to cut along the cable's direction to separate the sheath from the internal core wires. Then, use pliers or an electrician's knife to cut the sheath along the cable's axial direction.

[0004] The above-mentioned technology has at least the following technical problems: In actual construction, the thickness of the cable sheath, the force with which the operator holds the knife, the sharpness of the knife tip, and the angle at which the sheath is stripped all contribute to the difficulty of completing the cable sheath removal work quickly and with high quality. Furthermore, due to the subjective and objective influences of the construction environment, the skill level of the personnel, and their physical condition, insufficient force may prevent the insulation from being stripped in one go; excessive force may damage the internal core wires. Improper operation may even cause the knife to slip off the cable sheath, resulting in injury to personnel or damage to other property.

[0005] To solve the above problems and improve cable stripping efficiency, there is an urgent need for a safe, reliable, and easy-to-operate cable stripping device. Summary of the Invention

[0006] To address the shortcomings of existing technologies and to achieve safe, reliable, simple, convenient, and efficient cable stripping before cable wiring, while minimizing the impact of the construction environment, personnel condition, and skill level on the process, and avoiding secondary injuries to personnel and cables, as well as repetitive work, this application provides a portable cable stripping device. This device features a blade locator with clamping and limiting functions at the front of the main body to fix and restrict the cable to be processed; a blade embedded in the main body for stripping the cable sheath; and a long handle with opening and closing semi-circular holes of different sizes near the blade at the lower part of the main body for cutting the insulation. This solves the technical problems associated with cable stripping.

[0007] The solution adopted by the embodiments of this application to solve the technical problem is: A portable cable stripping device includes a main body, a blade, a blade positioner, and a long handle; The cable stripping device has an embedded elongated groove structure to hold the blades for stripping the cable sheath. The blades reciprocate within the groove structure via a tool positioning button and lock at any travel position. A tool positioner is mounted at the front of the device to fix and restrict the cable to be stripped. The tool positioner includes a positioning rod knob, a movable positioning rod, and double clamping arms for limiting the movement. The tool positioner is held onto the cable by the double clamping arms, and the relative position and angle between the device and the cable can be adjusted via the positioning rod knob and the movable positioning rod. A long, openable handle is located on one side of the device, with semi-circular openings of different sizes. The handle and the blade interact to cut the stripped cable sheath.

[0008] To further address the technical problems addressed in the embodiments of this application, the tool positioner provided in this application connects the movable positioning rod to the main body of the cable stripping device via a positioning rod knob. The movable positioning rod and the double clamping arm limiter are integrated into one structure. The double clamping arm limiter is used to fix the cable to be processed, and by loosening the positioning rod knob on the tool positioner, the angle between the main body of the cable stripping device and the tool and the cable to be processed is adjusted along the axial direction of the positioning rod knob.

[0009] Furthermore, the feed positioning button is installed together with the cutter. By moving the feed positioning button, the tip of the cutter is inserted into the cable sheath, and the position of the cutter is locked by the feed positioning button. The cutter is a double-edged blade, that is, the bottom edge and the front edge of the cutter both have cutting edges.

[0010] Furthermore, each clamping arm of the double clamping arm limiter has several stops, and rolling bearings are installed between the stops. There is an elastic connection between the two clamping arms of the double clamping arm limiter to ensure that the opening and closing of the double clamping arm limiter allows the bearings to come into contact with the cable to be processed. When the main body of the cable stripping device moves along the cable to be processed, the bearings rotate under the action of the stops, making the main body of the cable stripping device move more smoothly and effortlessly.

[0011] Furthermore, a long handle is located on one side of the main body of the cable stripping device and opens and closes. The long handle has semi-circular openings of different sizes, which cooperate with the bottom blade of the cutter to cut the connection between the stripped cable sheath and the main body of the cable to be processed, thus completing one stripping process.

[0012] Positive effects: Because the main body of this cable stripping device is equipped with a cutter positioner, the device can be easily fixed together with the cable to be treated by the double clamping arms on the cutter positioner. Furthermore, the installation and disassembly of the double clamping arm structure device are simple and convenient. Because this tool positioner is equipped with a positioning rod knob and a movable positioning rod, the angle adjustment range between the main body of the processing device and the tool and the cable to be processed is large, making operation convenient and flexible; The blade of this cable stripping device is equipped with a locking function for the infeed positioning button, which ensures that the blade remains in the same infeed position and cutting depth during the cable stripping process. The double clamping arms of this cable stripping device are equipped with several rolling bearings, which fix and limit the relative position of the cable and the cutter, ensuring that the cutter can move in a straight line along the cable to be cut. During the cutting motion, there will be no slippage or deviation with the cable, thus effectively ensuring that the depth of the cable sheath cut is consistent throughout the entire stroke. The rolling bearings can keep the cutting process of the device smooth and easy.

[0013] In addition, by using this device, construction workers do not need to consciously control the direction and cutting depth of the blade through wrist and arm muscles, thus avoiding the risk of the blade slipping off the cable sheath and injuring people or damaging the cable, reducing the difficulty of operation and improving construction efficiency.

[0014] It is suitable for use as a portable cable stripping device. Attached Figure Description

Detailed Implementation

[0018] 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. Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] according to Figure 1-4 As shown, a portable cable stripping device includes a cable stripping device body 1, a blade 4, a blade positioner 5, and a long handle 6. The main body 1 of the cable stripping device is embedded with a long groove structure 3, which is used to hold the cutter 4 for stripping the cable sheath. The cutter 4 moves back and forth in the long groove structure 3 through the cutter positioning button 2 and is locked at any stroke position. The front of the main body 1 of the cable stripping treatment device is equipped with a cutter positioner 5, which is used to fix and restrict the cable 12 to be treated. The cutter positioner 5 includes a positioning rod knob 7, a movable positioning rod 8, and a double clamping arm limiter 9. The cutter positioner 5 is clamped on the cable 12 to be treated by the double clamping arm limiter 9, and the relative position and angle between the main body 1 of the cable stripping treatment device and the cable 12 to be treated are adjusted by the positioning rod knob 7 and the movable positioning rod 8. The main body 1 of the cable stripping device has an opening and closing long handle 6 on one side for cutting the stripped cable sheath.

[0020] Specifically, in this embodiment, the cable stripping device uses a cutter positioner 5 with an openable side and a cable clamping and positioning device at the front of the main body 1. Simply clamp the cable to be stripped in the cutter positioner 5 at the front of the device, adjust the cutter positioning button 2 of the clamping device to align the blade tip of the cable stripping device with the surface of the cable sheath, and adjust the cutting angle. Then, adjust the cutting positioning button 2 to insert the cutter 4 into the cable sheath to a suitable depth and lock the cutting position. Finally, straighten the cable 12 to be stripped and manually slide the stripping point along the cable direction. The main body 1 of the cable stripping device and the tip of the blade 4 easily peel off the cable sheath. After peeling to the designated position, the main body 1 of the cable stripping device is separated from the cable. Then, the long handle 6 with the blade on one side of the cable stripping device 1 is opened, a semi-circular hole of appropriate size is selected, and appropriate force is applied to hold the stripped position. The main body 1 of the cable stripping device is rotated to completely separate the cable from the stripped insulation. Using this cable stripping device, the outer insulation sheath and the outer sheath of the core wire can be removed conveniently and quickly, ensuring the quality of stripping, reducing the labor intensity of construction workers, and ensuring construction safety.

[0021] Specifically, in this embodiment, the cable stripping device includes a main body 1 equipped with a detachable blade. The front of the main body 1 has a blade locator 5 with a clamping and limiting function. The main body 1 has a groove-shaped structure for inserting an electrician's blade. The blade can slide forward and backward in the groove-shaped structure and can be locked at any position by the blade positioning button 2. The lower part of the main body 1 near the blade edge is provided with a long handle 6 with semi-circular holes of different sizes that can be opened and closed for cutting the insulation.

[0022] Specifically in this embodiment, the cutter 4 is installed in the elongated groove structure 3 on the main body 1 of the cable stripping device. The front end of the elongated groove structure 3 is open, which makes it easy for the cutter tip of appropriate length to slide out of the groove structure and strip the cable sheath. The tail end of the cutter 4 is equipped with a cutter positioning button 2, which makes it easy to control the cutting of the cutter 4 and lock the cutting length of the cutter 4 to ensure that the cutting depth of the cable sheath is appropriate.

[0023] The infeed positioning button 2 is installed together with the cutter 4. By moving the infeed positioning button 2, the tip of the cutter 4 can be inserted into the cable sheath, and the position of the cutter 4 can be locked by the infeed positioning button 2. The cutter 4 is a double-edged blade, that is, the bottom edge and the front edge of the cutter 4 have cutting edges, which makes it easy for the tip to insert into the cable sheath and for the bottom cutting edge to cut the cable sheath.

[0024] The tool positioner 5 connects the movable positioning rod 8 to the main body 1 of the cable stripping device via the positioning rod knob 7. The movable positioning rod 8 and the double clamping arm limiter 9 are an integral structure. The double clamping arm limiter 9 is used to fix the cable 12 to be processed. By loosening the positioning rod knob 7 on the tool positioner 5, the angle between the main body 1 of the cable stripping device and the tool 4 and the cable 12 to be processed can be adjusted along the axis of the positioning rod knob 7, so as to facilitate the cutting of the tool 4 and the stripping process.

[0025] Each clamping arm of the double clamping arm limiter 9 has several stops 10, and a rolling bearing 11 is installed between the stops 10. The two clamping arms of the double clamping arm limiter 9 are elastically connected to ensure that the double clamping arm limiter 9 can open and close effectively, so that the bearing 11 and the cable 12 to be treated come into contact, thereby effectively fixing the cable 12 to be treated. When the main body 1 of the cable stripping device moves along the cable 12 to be treated, the bearing 11 rotates under the action of the stops 10, making the main body 1 of the cable stripping device move more smoothly and effortlessly, thereby quickly and effectively stripping the insulation of the cable 12 to be treated.

[0026] Specifically, a number of rolling bearings 11 are mounted on the double clamp arm limit 9, and the bearings 11 are isolated from each other by the stop 10.

[0027] A long handle 6 is located on one side of the main body 1 of the cable stripping device and can be opened and closed. The long handle 6 has semi-circular openings of different sizes, which can cooperate with the bottom blade of the blade 4 to cut the connection between the stripped cable sheath and the main body of the cable 12 to be processed, thus completing one stripping process. In this embodiment, the long groove-shaped structure 3 on the main body 1 of the cable stripping device has a long opening near the blade, and the long handle 6 that can be opened and closed is provided on the outside of the opening.

[0028] The working process of this embodiment: The steps are as follows: 1. Select the appropriate cable stripping device body 1 according to the outer diameter of the cable 12 to be processed; 2. Clamp the double clamping arm limiter 9 onto the cable to be processed 12, loosen the positioning rod knob 7, adjust the cable stripping device body 1 and the cable to be processed 12 to a suitable angle, and then lock the positioning rod knob 7 to put the double clamping arm limiter 9 in the locked position. 3. Slide the device to one end of the cable 12 to be processed, push the infeed positioning button 2, so that the tip of the cutter 4 slowly pierces the cable sheath and is inserted to the appropriate depth in the cable. Then rotate the infeed positioning button 2 to lock the infeed position of the cutter 4. 4. Move the main body 1 of the cable stripping device at a constant speed along the direction of the cable 12 to be processed. The bearing 11 on the double clamp arm limit 9 rolls along the cable at the clamped position, driving the cutter 4 to smoothly strip the cable sheath. 5. Once the cutter 4 and the double clamping arm limiter 9 have traveled through the appropriate length of cable sheath, the cable sheath can be peeled off. Then, the double clamping arm limiter 9 can be released and the cable can be removed, thus completing one stripping process.

[0029] 6. If the cable 12 to be treated is thick, several slits need to be made, and steps 2 to 5 can be repeated on the cable to be treated.

[0030] 7. After the insulation of the cable 12 to be processed is stripped, loosen the infeed positioning button 2, fully retract the cutter 4 into the long groove structure 3, and then tighten the infeed positioning button 2.

[0031] 8. Remove the tool positioner 5 from the cable 12 to be treated. Open the long handle 6 on one side, select a semi-circular hole with a suitable outer diameter for the cable 12 to be treated, install the cable 12 to be treated into the semi-circular hole, and adjust it to the connection point between the stripped and unstripped cable; 9. Close the long handle 6 and wed the cable 12 to be processed between the semi-circular hole of the long handle 6 and the lower blade of the cutter 4. Apply appropriate force to make the blade cut into the cable sheath to a suitable depth, and rotate the stripping device along the cable axis to separate the stripped cable sheath from the cable body, completing one cable sheath stripping process; 10. The method of stripping the insulation layer of the cable core wire by this processing device is the same as that of stripping the outer sheath of the cable.

[0032] Features of this embodiment: Because this cable stripping device is equipped with a cutter positioner 5, the device can be easily fixed together with the cable 12 to be processed by the double clamping arm limiter 9 on the cutter positioner 5. The installation and disassembly of the double clamping arm limiter 9 structure device is simple and convenient.

[0033] Because the tool positioner 5 is equipped with a positioning rod knob 7 and a movable positioning rod 8, the angle adjustment range between the main body 1 of the processing device and the tool 4 and the cable 12 to be processed is large, making the operation convenient and flexible.

[0034] Because the cutter 4 of this cable stripping device is equipped with a cutting position button 2 with a locking function, it can be ensured that the cutter 4 is always in the same cutting position and cutting depth during the process of stripping the cable.

[0035] Because the double clamping arm limiter 9 of this cable stripping device is equipped with several rolling bearings 11, the double clamping arm limiter 9 can fix and limit the relative position of the cable to be processed 12 and the cutter 4, ensuring that the cutter 4 can move in a straight line along the cable to be processed 12. During the cutting motion, it will not slip or deviate from the cable to be processed 12, thereby effectively ensuring that the depth of the cable sheath cut is consistent throughout the entire stroke. The rolling bearings 11 can keep the cutting process of the device smooth and even.

[0036] Because this cable stripping device has a long handle 6 with a semi-circular hole on one side that can be used with a blade 4 to cut off the stripped cable sheath, the cable stripping process can be easily completed using only this single tool.

[0037] In addition, by using this cable stripping device, construction workers do not need to consciously control the direction and cutting depth of the blade 4 through wrist and arm muscles, thus avoiding the risk of the blade 4 slipping off the cable sheath and injuring people or damaging the cable, reducing the difficulty of operation and improving construction efficiency.

[0038] Finally, it should be noted that: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
