Description

Technical Field

[0001] The invention relates to the technical field of wire stripping tools, and in particular to a quick wire stripping device. Background Art

[0002] In the daily work of power construction, wire stripping is the most basic and frequent work. The speed and quality of wire stripping directly affect the progress of the entire construction. The existing wire stripping method is generally that workers use wire strippers to strip the insulation layer of the wire to expose the copper core wrapped in the insulation layer. The disadvantage of this method is that the wire stripper can only strip the insulation layer of the end of the wire and the insulation skin is not neat after stripping. At the same time, it is also impossible to strip the insulation layer at any part of the wire. Even if it can be done, its construction efficiency is extremely low, and there are certain safety hazards when stripping the insulation layer of the live wire. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a quick wire stripping device, which solves the problem that the wire strippers in the prior art can only strip the insulation layer of the end of the wire but cannot strip the insulation layer at any part of the wire.

[0004] According to an embodiment of the present invention, a quick wire stripping device includes: a mounting barrel, which is in the shape of a cylindrical barrel, a wire stripping hole is coaxially arranged in the mounting barrel, and a first channel for connecting the outside world with the wire stripping hole is arranged on the side wall of the mounting barrel; a mounting ring, the surface of the mounting barrel is recessed to form a first mounting groove surrounding it, the mounting ring is rotatably arranged in the first mounting groove, and a second channel for connecting the outside world with the first channel is arranged on the side wall of the mounting ring, and the first channel and the second channel are used for inserting the wire into the wire stripping hole; a cutting knife, a rotating groove surrounding the bottom of the first mounting groove is opened, and the rotating groove is connected to the wire stripping hole, and a side of the mounting ring close to the mounting barrel is recessed to form a second groove, and a mounting component for installing the cutting knife is arranged in the second groove, and the cutting knife passes through the rotating groove and is inserted into the wire stripping hole; and a clamping component, the top and bottom of the wire stripping hole are symmetrically provided with first grooves, and the clamping component is installed in each first groove, and the two clamping components are used to clamp the wire in the wire stripping hole.

[0005] The technical principle of the present invention is as follows: when using the wire stripping device to strip the insulating layer on the wire to expose the copper core, first adjust the clamping assembly so that it does not block the wire from being inserted into the wire stripping hole from the first channel of the mounting barrel, and by observing and fine-tuning the position of the mounting barrel, when the wire moves to the center of the wire stripping hole (that is, the axis of the wire coincides with the axis of the wire stripping hole), control the clamping assemblies at the top and bottom of the wire stripping hole to clamp the wire, and then adjust the position of the cutting knife (that is, the distance from the tip of the cutting knife to the axis of the wire stripping hole) by controlling the mounting assembly, so that the tip of the cutting knife passes through the insulating layer and contacts the copper core, and then rotate the mounting ring in the rotating groove for one circle to cut off the insulating layer, and then repeat the above operation to cut the insulating layer on the other side of the wire, and finally push the mounting barrel along the direction of the axis of the wire to move toward another cut position of the wire, and then rotate the mounting ring to adjust the position of the cutting knife to scratch the insulating layer again, so that the cutting knife cuts the insulating layer into four pieces, and the insulating layer falls off the copper core, thus achieving the stripping of the insulating layer.

[0006] Compared with the prior art, the present invention has the following beneficial effects: the device is provided with a rotatable mounting ring on the mounting cylinder, and a cutting knife is provided on the mounting ring through the mounting assembly. When the mounting ring is rotated, the cutting knife cuts the insulating layer on the wire, and then the device is used to cut the insulating layer on another part of the wire, and finally the cutting knife is used to scratch the insulating layer so that the insulating layer falls off the wire. The device can strip the wire at any position of the wire, so as to expose the copper core of the wire at the position where the wire needs to be connected to the outside world. At the same time, the device directly contacts the base of the human body and is made of insulating material. It can open and strip the wire at the required position of the live insulated wire, which is convenient for quick connection of the wire. At the same time, the device is simple to operate and convenient for workers to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0015] like Figure 1 as well as Figure 2As shown, an embodiment of the present invention proposes a quick wire stripping device, including: a mounting barrel 1, which is in the shape of a cylindrical barrel, a wire stripping hole 2 is coaxially arranged in the mounting barrel 1, and a first channel 3 is arranged on the side wall of the mounting barrel 1 to connect the outside with the wire stripping hole 2; a mounting ring 5, the surface of the mounting barrel 1 is recessed to form a first mounting groove 4 surrounding it, the mounting ring 5 is rotatably arranged in the first mounting groove 4, and a second channel 6 is arranged on the side wall of the mounting ring 5 to connect the outside with the first channel 3, and the first channel 3 and the second channel 6 are used for inserting the wire 7 into the wire stripping hole 2; a cutting knife 10, the bottom of the first mounting groove 4 A rotating groove 11 is provided around the bottom thereof, the rotating groove 11 is communicated with the wire stripping hole 2, the side of the mounting ring 5 close to the mounting cylinder 1 is recessed to form a second groove 9, a mounting assembly for mounting a cutting knife 10 is provided in the second groove 9, the cutting knife 10 is inserted into the wire stripping hole 2 through the rotating groove 11; and a clamping assembly, the top and bottom of the wire stripping hole 2 are symmetrically provided with first grooves 8, each first groove 8 is installed with the clamping assembly, the two clamping assemblies are used to clamp the wire 7 in the wire stripping hole 2, the mounting cylinder 1, the mounting ring 5, the mounting assembly and the clamping assembly are all made of insulating material. When using the wire stripping device to strip the insulating layer 701 on the wire 7 to expose the copper core 702, first adjust the clamping assembly so that it does not block the wire 7 from being inserted into the wire stripping hole 2 from the first channel 3 of the mounting barrel 1. By observing and fine-tuning the position of the mounting barrel 1, when the wire 7 moves to the center of the wire stripping hole 2 (i.e., the axis of the wire 7 coincides with the axis of the wire stripping hole 2), control the clamping assemblies at the top and bottom of the wire stripping hole 2 to clamp the wire 7. Then, adjust the position of the cutting knife 10 (i.e., the distance from the tip of the cutting knife 10 to the axis of the wire stripping hole 2) by controlling the mounting assembly to make the cutting knife 10 The tip of the cutting knife 10 passes through the insulating layer 701 and contacts the copper core 702, then the mounting ring 5 is rotated in the rotating groove 11 for one rotation to cut off the insulating layer 701, and then the above operation is repeated to cut the insulating layer 701 on the other side of the wire 7, and finally the mounting cylinder 1 is pushed along the axis of the wire 7 toward another cut position of the wire 7, and the mounting ring 5 is rotated again to adjust the position of the cutting knife and cut the insulating layer 701 again, so that the cutting knife 10 cuts the insulating layer 701 into four pieces, and the insulating layer 701 falls off the copper core 702, thus realizing the stripping of the insulating layer 701.

[0016] The device is provided with a rotatable mounting ring 5 on the mounting tube 1, and a cutting knife 10 is provided on the mounting ring 5 through a mounting assembly. When the mounting ring 5 is rotated, the cutting knife 10 cuts the insulating layer 701 on the wire 7, and then the device is used to cut the insulating layer 701 on another part of the wire 7, and finally the cutting knife 10 scratches the insulating layer 701 so that the insulating layer 701 falls off the wire 7. The device can strip the wire 7 at any position of the wire 7, so as to expose the copper core 702 of the wire 7 at the position where the wire 7 needs to be connected to the outside world. At the same time, the device directly contacts the base of the human body with insulating materials, and can open and strip the wire at the required position of the live insulated wire 7, so as to facilitate quick connection of the wire 7. At the same time, the device is simple to operate and convenient for workers to use.

[0017] like Figure 3 As shown, the mounting assembly includes: a screw rod 12, a sliding seat 13 and a second spring 14, the sliding seat 13 is slidably arranged in the second groove 9, the second spring 14 is arranged between the sliding seat 13 and the side wall of the second groove 9 facing away from the mounting cylinder 1, one end of the connecting rod 15 is arranged on the side of the sliding seat 13 close to the mounting cylinder 1, the other end of the connecting rod 15 passes through the rotating groove 11 and is inserted into the wire stripping hole 2, the cutting knife 10 is arranged on the end of the connecting rod 15 inserted into the wire stripping hole 2, the screw rod 12 is vertically inserted into the second groove 9 from the outside of the mounting ring 5 and is tightly attached to the sliding seat 13, the screw rod 12 is used to push the sliding seat 13 to move in the vertical direction in the second groove 9, and a scale indicating the vertical distance from the tip of the cutting knife 10 to the axis center of the wire stripping hole 2 is arranged on the screw rod 12. When the scale on the screw rod 12 is aligned with the surface of the mounting ring 5, the scale indicates the vertical distance from the cutting knife 10 to the axis center of the wire stripping hole 2. According to the relevant national requirements, the cross-sectional area of ​​the copper core 702 is 1 square millimeter (mm 2 ), 1.5 square millimeters (mm 2 ), 2.5 square millimeters (mm 2 ), 4 square millimeters (mm 2 ), 6 square millimeters (mm 2 ), 10 square millimeters (mm 2 ), 16 square millimeters (mm 2 ), 25 square millimeters (mm 2 ), 35 square millimeters (mm 2 ), 50 square millimeters (mm 2 ), 70 square millimeters (mm 2 ), 95 square millimeters (mm 2 ), 120 square millimeters (mm 2 ), 150 square millimeters (mm 2 ), 185 square millimeters (mm 2), etc., the staff can pre-judge the cross-sectional area of ​​the copper core 702 in the conductor 7 and then calculate the radius of the copper core 702. The end of the installation tube 1 can be provided with a marking scale for measuring the cross-sectional area of ​​the copper core 702 of the conductor 7, that is, when the copper core 702 of the conductor 7 is aligned with the marking scale, the cross-sectional area of ​​the copper core 702 can be directly read, which is convenient for the workers to judge, and then adjust the position of the cutting knife 10 according to the scale on the screw rod 12, so that the tip of the cutting knife 10 can just contact the surface of the copper core 702 in the conductor 7. When adjusting the cutting knife 10, continue to twist the screw rod 12, and the screw rod 12 can push the sliding seat 13 to slide in the second groove 9, so as to adjust the cutting knife 10 close to the conductor 7. When the screw rod 12 is away from the sliding seat 13, the cutting knife 10 is pulled into the second groove 9 by the sliding seat 13 under the elastic force of the second spring 14.

[0018] like Figure 1 As shown, each of the clamping assemblies includes: a sliding column 16 and a first spring 18, one end of the sliding column 16 is vertically inserted into the first groove 8 from the outside of the mounting tube 1, the sliding column 16 is slidably connected with the mounting tube 1, a mounting block 17 is provided on the side wall of one end of the sliding column 16 located in the first groove 8, one end of the first spring 18 is fixed on the side wall of the mounting block 17 away from the stripping hole 2, and the other end of the first spring 18 is fixed on the side wall of the first groove 8 away from the stripping hole 2, and the sliding column 16 is inserted into the stripping hole 2 under the elastic force of the first spring 18, and a clamping block 19 is provided on the end of the sliding column 16 located in the stripping hole 2. The working principle of the clamping assembly is: when the wire 7 moves to the axis of the stripping hole 2, the two sliding columns 16 are released, and under the elastic force of the first spring 18 in the corresponding first groove 8, the two clamping blocks 19 clamp the wire 7, and at the same time, the other end of the wire 7 is straightened by hand to ensure that the axis of the wire 7 coincides with the axis of the stripping hole 2.

[0019] like Figure 4 As shown, each of the clamping blocks 19 is in an arc shape, and a clamping pad 20 is provided on one side of each of the clamping blocks 19 close to the axis of the stripping hole 2. Arranging the clamping block 19 in an arc shape can increase the contact area between the clamping block 19 and the wire 7, so that the effect of clamping the wire 7 is better.

[0020] Each of the pressing pads 20 is made of rubber material. The advantage of arranging the pressing pad 20 on the pressing block 19 and using the pressing pad 20 made of rubber material is that the pressing block 19 can ensure that the pressing pad 20 is compacted. At the same time, when the cutting knife 10 is used to cut the insulating layer 701 of the wire 7 in the horizontal direction, the wire 7 can be straightened by hand to improve the cutting effect.

[0021] like Figure 5As shown, the bottom of the first mounting groove 4 is recessed to form a plurality of second mounting grooves 21, and a guide assembly is arranged in each second mounting groove 21. Each of the guide assemblies is a ball 22, and each ball 22 is rollingly arranged in the corresponding second mounting groove 21, and one side of each ball 22 extends into the first mounting groove 4, and the mounting ring 5 is in close contact with the ball 22. The advantage of arranging the guide assembly at the bottom of the first mounting groove 4 is that the friction between the mounting ring 5 and the mounting cylinder 1 can be reduced, making it more labor-saving when rotating the mounting ring 5.

[0022] like Figure 1 as well as Figure 2 As shown, it also includes a stop ring 23, the surface of the mounting tube 1 is recessed to form a step, the bottom of the step is located on the same horizontal plane as the bottom of the first mounting groove 4, the bottom of the step is recessed to form at least one third groove 24, the stop ring 23 is sleeved on the step, the stop ring 23 is tightly attached to the mounting ring 5, and each of the third grooves 24 is provided with a clamping assembly for clamping the stop ring 23 on the step. Since the cutting blade 10 is easy to wear after long-term use, the cutting blade 10 needs to be replaced regularly, that is, the mounting ring 5 needs to be removed from the mounting tube 1, and the steps of removing the mounting ring 5 are as follows: first, control the clamping assembly to release the stop ring 23, then remove the stop ring 23 in the direction away from the mounting tube 1, and finally pull the mounting ring 5 out in the direction away from the mounting tube 1.

[0023] like Figure 6 As shown, each of the clamping components includes: a stop pin 26 and a push rod 28, a third spring 25 is arranged in the third groove 24, the stop pin 26 is slidably arranged in the third groove 24, a stop hole corresponding to the stop pin 26 is provided on the stop ring 23, the stop pin 26 is inserted into the corresponding stop hole under the elastic force of the third spring 25, a slide groove 27 is provided on the side wall of the installation tube 1 to connect the outside with the third groove 24, one end of the push rod 28 passes through the slide groove 27 from the outside and is inserted into the third groove 24 and is fixedly connected with the stop pin 26, and the push rod 28 is used to push the stop pin 26 out of the stop hole. The working principle of the clamping component is: when the stop pin 26 is inserted into the stop hole, the stop pin 26 blocks the stop ring 23 from being separated from the installation tube 1, and when the stop ring 23 needs to be removed, it is only necessary to push the push rod 28 to push the stop pin 26 out of the stop hole.

[0024] like Figure 1 As shown, it also includes: a base 29, the top of the base 29 is recessed to form a receiving groove 30, the receiving groove 30 is provided with an internal thread, the limiting ring 23 is provided with an external thread 31, the limiting ring 23 is inserted into the receiving groove 30, the limiting ring 23 is threadedly connected to the receiving groove 30, and the push rod 28 does not contact the bottom of the receiving groove 30.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
