Description

Technical Field

[0001] The invention relates to the field of electric tools, and in particular to a live working insulated wire stripping tool and a use method thereof. Background Art

[0002] When installing or repairing power cables, electricians need to strip the insulation layer on the outside of the cable to make connections. Traditional stripping tools include electrician's knives, hook knives, and wallpaper knives. However, since the cables are usually suspended in the air and their insulation layer is thick and hard, electricians often need to apply greater force when operating, which can easily cause injuries and damage the internal structure of the cable. Therefore, the process of stripping the cable outer sheath using these stripping tools poses a safety hazard.

[0003] The stripping tools currently used require complicated operations to strip wires of different types.

[0004] The outer skin of the wire is rough and slippery. Currently, most people use hands to hold it to prevent it from rotating, which is not only ineffective but also inefficient. Summary of the invention

[0005] In order to solve the deficiencies in the prior art, the present invention provides a live working insulated wire stripping tool and a method of using the tool.

[0006] The present invention adopts the following technical solution:

[0007] A live working insulated wire stripping tool, comprising: an active part, a driven part, a transmission ratchet disc, a driven ratchet disc, a stripping part and an anti-loosening fixing piece;

[0008] A notch is provided on the driven ratchet disc; a pair of driving ratchet discs are arranged on the lower side of the driven ratchet disc in mirror image on the left and right sides;

[0009] The ratchet teeth of the driving ratchet disc and the driven ratchet disc are in contact;

[0010] The peeling part is arranged in the driven ratchet disc, and one end of the peeling part away from the peeling knife is rotatably connected to the inner wall of the driven ratchet disc;

[0011] The anti-loosening fixing piece presses against one end of the stripping knife close to the stripping portion, and the stripping knife always touches the outer wall of the cable that needs to be stripped.

[0012] According to the live working insulated wire stripping tool, the insulated wire stripping tool further comprises: a center calibration guide;

[0013] The center calibration guide part comprises: a driving unit, a center calibration platform, and a center calibration rotating member;

[0014] An inclination movement support rod is arranged on the center calibration table, and a pair of inclination surfaces that cooperate with the inclination movement support rod are provided. A spring member is sleeved outside the first rotation bar of the center calibration rotating member, and a restraint bar is arranged at one end of the first rotation bar close to the inclination movement support rod;

[0015] The driving unit controls the movement of the center calibration table and the inclination movement support rod. After the pair of inclination surfaces on the inclination movement support rod touch the corresponding restraint bars, under the action of the force, they resist the force generated by the elastic deformation of the spring member, so that the restraint bars move along the inclination surfaces, and then the second rotation bar of the center calibration rotating member rotates inward, and then the wire is clamped at the center.

[0016] According to the live working insulating wire stripping tool described above, a pair of inclination movement support rods are arranged in mirror symmetry on the front and rear sides of the center calibration table, and center calibration rotating members are arranged at the corresponding positions of the inclination movement support rods.

The first support member and the second support member are connected in a detachable manner through fixing members such as pins;

[0020] The movable support member is arranged at the tail of the first support member. The tails of the second support member and the movable support member are rotatably installed on the inner wall of the driven ratchet disc. The pin passes through the pin hole on the second support member, and the tail of the pin jacks up the movable support member to move upward, so that the lower side of the tail end of the second support member and the upper side of the tail end of the movable support member are inserted into the movable connection ports on the upper and lower sides of the driven ratchet disc, thereby realizing the movable connection.

[0024] The driven part includes: a first driven part and a second driven part. The first driven part can adopt a bevel gear, and the second driven part can adopt a cylindrical gear; the motor drives the first driven part to rotate through a coupling. Since the first driven part and the second driven part are coaxial, the second driven part can be driven to rotate simultaneously, and the driving ratchet disc is driven to rotate through the second driven part.

[0025] According to the live working insulated wire stripping tool described above, an auxiliary rotating wheel corresponding to the outer shape of the wire is provided at the tail of the second rotating bar of the central calibration rotating part.

[0028] S2. Operate the central calibration guiding part to move synchronously towards the center and clamp the wire;

[0029] S3. Operate the active part to make the driven ratchet disc rotate. A pair of driving ratchet discs drive the driven ratchet disc to rotate on the left and right sides, so that the stripping knife cuts the outer skin of the wire;

[0030] S4. After the stripping knife completely cuts open the outer skin of the wire, under the action of the displacement restriction of the wire by the auxiliary rotating wheel, hold the handle and pull the stripping tool along the axial direction of the wire to strip the outer skin of the wire;

[0093] Please refer to Figures 1 - 15 :

[0094] The present invention provides an insulating wire stripping tool for live working, including: an active part, a driven part, a transmission ratchet disc 2, a driven ratchet disc 3, a stripping part 4 and an anti-loosening fixing part 5.

[0095] Please refer to Figure 7 :

[0096] The driven ratchet wheel 3 is provided with a notch 49; a pair of driving ratchet wheels 2 are arranged in a left-right mirror image on the lower side of the driven ratchet wheel 3. When the notch 49 on the driven ratchet wheel 3 rotates to any one of the pair of driving ratchet wheels 2, this driving ratchet wheel 2 can no longer drive the driven ratchet wheel 3 to rotate, while the ratchets between the other driving ratchet wheel 2 and the driven ratchet wheel 3 are in contact to ensure the uninterrupted transmission, thereby ensuring that the driving ratchet wheel 2 continuously drives the rotation of the driven ratchet wheel 3.

[0097] Please refer to Figures 7 - 10 :

[0098] Power is transmitted from the driving part to the driven part to drive a pair of driving ratchet wheels 2 to rotate.

[0099] The driving part includes: a motor 44;

[0100] The driven part includes: a first driven part 45 and a second driven part 46. The first driven part 45 can adopt a bevel gear, and the second driven part 46 can adopt a cylindrical gear; the motor 44 drives the first driven part 45 to rotate through a coupling 47. Since the first driven part 45 and the second driven part 46 are coaxial, the second driven part 46 can be driven to rotate simultaneously. The driving ratchet wheel 2 is driven to rotate through the second driven part 46, and the power is transmitted through the contact between the ratchets of the driven ratchet wheel 3 and the driving ratchet wheel 2; the rotation of the driving ratchet wheel 2 causes the rotation of the driven ratchet wheel 3. Through this power transmission mechanism, the driving part drives the driven ratchet wheel 3 to rotate.

[0101] Please refer to Figures 1 - 8 :

[0102] The peeling part 4 is arranged inside the driven ratchet wheel 3. One end of the peeling part 4 away from the peeling knife 54 is rotatably connected to the inner wall of the driven ratchet wheel 3; the anti-loosening fixing part 5 abuts against one end of the peeling part 4 close to the peeling knife 54 to prevent it from loosening, ensuring that the peeling knife 54 always touches the outer wall of the cable to be peeled.

[0103] Please refer to Figure 13 And Figure 14 :

[0104] The peeling part 4 includes: a peeling knife support mechanism 27, a peeling knife receiving cavity 31, and a peeling knife 54. The peeling knife support mechanism 27 includes: a first support member 28, a second support member 29, and a movable support member 30; corresponding peeling knife receiving cavities 31 are provided on the first support member 28 and the second support member 29, and the peeling knife 54 is installed in the peeling knife receiving cavity 31. The first support member 28 and the second support member 29 are connected in a detachable manner through fixing members such as pins. A protective platform 50 is provided at the head of the peeling knife receiving cavity 31; the protective platform 50 is used to reduce the wear of the peeling knife 54 and enhance the structural toughness and reliability of the installation location of the peeling knife 54.

[0105] The movable support member 30 is provided at the tail of the first support member 28. The tails of the second support member 29 and the movable support member 30 are rotatably installed on the inner wall of the driven ratchet disc 3. The pin passes through the pin hole 32 on the second support member 29, and the tail of the pin jacks up the movable support member 30 to move upward. Then, the lower side of the tail end of the second support member 29 and the upper side of the tail end of the movable support member 30 are inserted into the movable connection port 34 on the upper and lower sides of the driven ratchet disc 3 through the movable connecting rod 33, so as to achieve the purpose of movable connection. And an elastic torsion member is arranged at the movable connection to return the peeling knife support mechanism 27 after the peeling operation is performed.

[0106] Please refer to Figure 12 :

[0107] A first stop post 52 is also arranged on the driven ratchet disc 3. The first stop post 52 is arranged near the movable connection between the peeling knife support mechanism 27 and the driven ratchet disc 3 to prevent the peeling knife support mechanism 27 from rotating too much. The connection method between the second support member 29 and the movable support member 30 is beneficial to the disassembly and assembly between the peeling knife support mechanism 27 and the driven ratchet disc 3.

[0108] Please refer to Figures 1 - 8 :

[0109] The anti-loosening fixing member 5 is a high-elastic metal plate. One end of the anti-loosening fixing member 5 is rotatably connected to the recessed groove 25 of the driven ratchet disc 3.

[0110] Please refer to Figure 11 Or Figure 12 :

[0111] Two stop holes 26 are formed on a pair of side walls of the driven ratchet disc 3. The other end of the anti-loosening fixing member 5 is in the stop holes 26 and can move in the stop holes 26.

[0112] Please refer to Figure 11 :

[0113] A second stop post 53 is arranged near the connection between the anti-loosening fixing member 5 and the recessed groove 25 to prevent the anti-loosening fixing member 5 from displacing and rotating. The outer protruding surface of the anti-loosening fixing member 5 abuts against the peeling knife support mechanism 27 to prevent it from moving, and the peeling knife 54 on the peeling knife support mechanism 27 always touches the outer wall of the cable to be peeled.

[0114] Please refer to Figures 3 - 10 :

[0115] This application further includes: a central calibration guiding portion;

[0116] The central calibration guiding part includes: a driving unit, a central calibration table 6, and a central calibration rotating part 7; an inclination moving support rod 8 is arranged on the central calibration table 6, and a pair of inclination surfaces 9 that cooperate with the inclination moving support rod 8 are arranged. A spring member 21 is sleeved outside the first rotating bar 20 of the central calibration rotating part 7, and a restraint bar 22 is arranged at one end of the first rotating bar 20 close to the inclination moving support rod 8; the driving unit controls the movement of the central calibration table 6 and the inclination moving support rod 8. After a pair of inclination surfaces 9 on the inclination moving support rod 8 touch the corresponding restraint bar 22, under the action of the acting force, it resists the acting force generated by the elastic deformation of the spring member 21, so that the restraint bar 22 moves along the inclination surface 9. During this movement, under the guidance of the inclination surface 9, the restraint bar 22 drives the central calibration rotating part 7 to rotate under the acting force at a certain angle, so that the second rotating bar 23 of the central calibration rotating part 7 rotates inward, and then the wire is clamped at the center.

[0117] After peeling, the driving column 43 of the pulse driver 42 moves back. Under the influence of the restoring force of the spring member 21, the central calibration rotating part 7 rotates in reverse, so that the second rotating bar 23 of the central calibration rotating part 7 rotates outward and no longer clamps the wire.

[0118] Please refer to Figure 7 :

[0119] A pair of inclination moving support rods 8 are arranged in mirror image on the front and rear sides of the central calibration table 6, and the central calibration rotating part 7 is arranged at the corresponding position of the inclination moving support rod 8, ensuring that a pair of central calibration guiding parts are provided on both the left and right sides of the driven ratchet disc 3, so as to ensure that the wire can be clamped at the center on both the front and rear sides.

[0120] Please refer to Figure 9 :

[0121] A dynamometer 41 is arranged at the central position of the central calibration table 6. The driving unit includes: a pulse driver 42, and the driving column 43 of the pulse driver 42 is at the central position of the dynamometer 41; the dynamometer 41 is electrically connected to the pulse driver 42. A threshold is determined in advance. When the magnitude of the acting force is smaller than the threshold, the driving column 43 of the pulse driver 42 moves outward and tightly abuts against the central calibration table 6. When the magnitude of the acting force shown by the dynamometer 41 reaches the threshold, the pulse driver 42 stops working, realizing the clamping of wires of various models at the center by the restraint bar 22.

[0122] At the tail of the second rotating bar 23 of the central calibration rotating part 7, an auxiliary rotating wheel 48 corresponding to the shape of the wire is provided. The auxiliary rotating wheel 48 plays a role in restricting the displacement of the wire, facilitating the operation of horizontally moving the wire stripping tool of the present application to strip the wire. Through the synchronous movement of the two pairs of auxiliary rotating wheels 48 towards the center, the wire is clamped to achieve the clamping operation at the center. In addition, rotating supports are provided at both ends of the first rotating bar 20 of the central calibration rotating part 7, and the rotating supports are fixedly connected to the inside of the machine body housing 37.

[0123] The design of the central calibration guiding part can not only clamp the wire to prevent the wire from rotating during wire stripping, but also the pulse driver and the dynamometer cooperate with each other to strip wires of different model sizes.

[0124] The present application further includes: a machine body housing 37 and a grip 38;

[0125] Please refer to Figure 4 :

[0126] A boss 39 is circumferentially provided on the driven ratchet disc 3, and a notch 40 cooperating with the boss 39 is provided on the machine body housing 37, thereby restricting the displacement of the driven ratchet disc 3.

[0127] The present application also provides a method for using an insulating wire stripping tool for live working:

[0128] S1. Insert the wire through the notch 49 of the driven ratchet disc 3;

[0129] S2. Operate the central calibration guiding part to move synchronously towards the center to clamp the wire;

[0130] S3. Operate the active part to make the driven ratchet disc 3 rotate. A pair of driving ratchet discs 2 drive the driven ratchet disc 3 to rotate on the left and right sides, so that the stripping knife 54 cuts the outer skin of the wire;

[0131] S4. After the stripping knife 54 completely cuts open the outer skin of the wire, under the action of the displacement restriction of the wire by the auxiliary rotating wheel 48, hold the grip 38 and pull the wire stripping tool along the axial direction of the wire to strip the outer skin of the wire;

[0132] S5. Withdraw the wire from the notch 49.

[0133] The structure and method of the present application are simple, the operation is also simple and efficient. It can not only achieve circumferential wire stripping, but also achieve axial wire stripping;

[0134] The present application designs a central calibration guiding part, which can not only clamp the wire to prevent the wire from rotating during wire stripping, but also the pulse driver and the dynamometer cooperate with each other to strip wires of different model sizes.

[0135] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the specific implementation manners of the present invention or make equivalent replacements, and any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered within the protection scope of the claims of the present invention.
