Description

Technical Field

[0001] The invention relates to the technical field of wire stripping tools, and in particular to a novel multifunctional insulated wire stripping pliers and a wire stripping method. Background Art

[0002] In actual work, the company's power grid construction personnel and line maintenance personnel responded that the old-fashioned pliers are time-consuming and labor-intensive and easily damage the wires, which will significantly affect work efficiency and increase the risk of line failures. Although another type of rotary-cut wire strippers on the market has reduced the damage rate of wires, they still have problems such as low efficiency and long stripping time. At the same time, both types of wire strippers can only achieve rotary cutting, and cannot quickly and effectively cut straight.

[0003] A Chinese patent application numbered CN201410543222.8 discloses a cable stripper, including a fixed seat and a sliding seat that are integrally arranged, wherein a fixed clamp head and a sliding clamp head are respectively arranged on the fixed seat and the sliding seat, and a space for clamping the cable is formed between the fixed clamp head and the sliding clamp head, and the sliding seat is also provided with an elastic tie rod connected to the sliding clamp head at one end, and the other end is arranged in the fixed seat, and the fixed seat is also provided with a cutter, a push rod with a scale, and a feed knob that are connected in sequence. For this wire stripping method, since the wire stripper can only perform rotary cutting, if the wire cutting length is too long, the staff needs to rotate the wire stripper continuously to operate it. After the cutting is completed, the wire sheath may be entangled on the wire, and the staff needs to slowly remove the wire sheath, which is cumbersome to operate and has low work efficiency.

[0004] The Chinese patent application number CN201510314654.6 discloses a labor-saving stripping device for stripping the insulation layer of wires, which adopts a two-stage lever structure, and is provided with a wire positioning groove and a stripping knife at the stripping operation end. The lever for fixing the knife adopts a separate hinge and an adjustment bolt adjustment device to adjust the optimal blade working distance in time according to the insulated wires of different cross-sections, so that a smaller force and working stroke are applied to the handle. However, since the force is applied by the handle during the cutting process, the staff cannot accurately control the force, which often damages the cables inside, posing a high safety hazard.

DETAILED DESCRIPTION

[0038] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0039] Example 1

[0040] In the prior art, rotary-cutting cable strippers can only perform rotary cutting. If the wire cutting length is too long, the worker needs to rotate the stripper continuously to operate. After the cutting is completed, the wire sheath may be entangled on the wire, and the worker needs to slowly remove the wire sheath, which is cumbersome and inefficient. In addition, wire strippers that can perform horizontal and vertical cutting need to use the handle to apply force during the cutting process. The worker cannot accurately control the force, which often damages the cable inside, posing a high safety hazard.

[0041] In view of the above problems, the present invention provides a novel multifunctional insulated wire stripper, which can simultaneously perform circumferential cutting and transverse cutting to achieve rapid stripping, and further utilizes a first adjustment mechanism to control the cutting depth of the down-cut blade 4.

[0042] like Figure 1 and Figure 2 As shown, including:

[0043] The clamping member includes a fixed seat 1 and a sliding seat 2, the fixed seat 1 and the sliding seat 2 are arranged opposite to each other, a clamping space 13 is formed between the fixed seat 1 and the sliding seat 2, and the size of the clamping space 13 is adjusted by the elastic component 3 when the sliding seat 2 approaches or moves away from the fixed seat 1.

[0044] When a force is applied to the sliding seat 2 in a direction away from the fixed seat 1, the elastic component 3 will provide a reverse force to the sliding seat 2. When the applied force is greater than the reaction force of the elastic component 3, the sliding seat 2 will slowly move away from the fixed seat 1, thereby increasing the clamping space 13 to facilitate the insertion of the insulated wire. After the force is removed, the force of the elastic component 3 causes the sliding seat 2 to reset to clamp the insulated wire. In addition, the elastic component 3 also plays a positioning role, allowing the sliding seat 2 to slide on a fixed track to ensure that the positions of the fixed seat 1 and the sliding seat 2 correspond.

[0045] In this embodiment, the fixing seat 1 is provided with a sliding groove 33 , and the elastic component 3 includes a connecting rod 31 slidably matched with the sliding groove 33 . The connecting rod 31 is sleeved with a third spring 32 located between the connecting rod 31 and the inner wall of the sliding groove 33 .

[0046] In this embodiment, external force is applied to drive the sliding seat 2 to move, and the connecting rod 31 extends out of the sliding groove 33. During the extension of the connecting rod 31, the third spring 32 is compressed to generate elastic force. At this time, the clamping space 13 becomes larger to facilitate the insertion of the insulated wire. After no external force is applied, the third spring 32 automatically resets to clamp and position the insulated wire.

[0047] In addition, the elastic component 3 can also be an elastic tie rod or an elastic band. In this embodiment, the elastic component 3 composed of a connecting rod 31 and a spring is selected to ensure the stability of the sliding seat 2 when it is pulled outward. The elastic tie rod and the elastic band are both soft to a certain extent and are prone to deflection when the sliding seat 2 is pulled.

[0048] A rotary cutting mechanism, which is located on one side of the fixing seat 1 and is used for performing circular cutting on the insulated wire;

[0049] The down-cutting mechanism includes a down-cutting blade 4 located on the other side of the fixing seat 1 and used for cross-cutting the insulated wire. The down-cutting blade 4 is connected to a first adjusting component 5 to control the transverse cutting depth of the down-cutting blade 4 .

[0050] Specifically, Figure 1 As shown, the rotary cutting mechanism is located at the front side of the fixing seat 1, and the down-cutting mechanism is located at the rear side of the fixing seat 1; the clamping space 13 is located between the rotary cutting mechanism and the down-cutting mechanism, and is used to place and position the insulated wire to be cut.

[0051] The working process of this embodiment is:

[0052] First, the insulated wire is clamped by the clamping space 13, and then the two ends of the stripping area are circumferentially cut by the rotary cutting mechanism to form an annular groove. After the annular groove is formed, the thickness of the insulating wire skin can be seen.

[0053] Finally, the position of the down-cutting blade 4 is adjusted by the depth of the annular groove, and the first adjusting component 5 is driven to accurately control the distance between the down-cutting blade 4 and the insulated wire and perform transverse cutting between the two annular grooves.

[0054] Since the down-cutting blade 4 is arranged at the rear side of the fixing seat 1, only the rear side of the insulated wire can be cut during transverse cutting, and the entire wire clamp is turned so that the down-cutting blade 4 is facing the front side of the insulated wire for transverse cutting. After the cutting is completed, the wire sheath of the insulated wire is directly divided into two halves, which is convenient for stripping.

[0055] Furthermore, a long handle 10 is provided at one end of the fixed seat 1, and a short handle 11 is provided at one end of the sliding seat 2; both the short handle 11 and the long handle 10 are covered with an anti-skid rubber sleeve 12. Specifically, the long handle 10 is fixedly installed at one end of the fixed seat 1, and the short handle 11 is fixedly installed at one end of the sliding seat 2, which is convenient for the staff to hold with both hands for operation. By setting the anti-skid rubber sleeve 12, the friction between the two hands and the short handle 11 and the long handle 10 is increased, so that the staff can firmly hold the long handle 10 and the short handle 11, ensuring the normal and safe conduct of the subsequent cutting work.

[0056] Furthermore, one of the side edges of the down-cut blade 4 is connected to the first adjustment component 5, and the other three side edges are provided with cutting edges. In this embodiment, the rear side edge of the down-cut blade 4 is connected to the first adjustment component 5, and the front side and left and right sides of the down-cut blade 4 are provided with cutting edges. During operation, when the down-cut blade 4 enters the annular groove to cut the insulated wire, since the down-cut blade 4 enters the annular groove to a certain depth, the cutting edges on the front and right sides of the down-cut blade 4 will cut the wire at the same time, so that the staff can complete the work quickly and smoothly. After that, the wire stripper turns, and the cutting edges on the left and front sides of the down-cut blade 4 will cut the insulated wire.

[0057] It can be seen from this that the cutting edge of the down-cut blade 4 is set according to the specific cutting operation conditions to improve the cutting efficiency of the operator.

[0058] Further, if Figure 2 and Figure 4 As shown, the first adjustment component 5 includes:

[0059] A driving block 51, wherein the driving block 51 is disposed on a side of the fixing base 1 close to the down-cutting blade 4, and a square groove 513 is formed in the driving block 51;

[0060] The first screw rod 52, one end of which is sleeved with a first spring 57 located in the square groove 513, and the other end of the first screw rod 52 is threadedly mounted with a first adjusting knob 53; since the first screw rod 52 slides in the square groove 513, the setting of the first spring 57 ensures the normal movement of the first screw rod 52 while preventing the first screw rod 52 from sliding out from the side close to the first adjusting knob 53.

[0061] The transmission member includes an integrally connected transmission shaft 55 and a square block 54. The transmission shaft 55 is fixedly connected to the first screw rod 52, and the square block 54 is slidably connected to the square slot 513. The end of the square block 54 located outside the square slot 513 is connected to a handle 56, and the handle 56 is connected to one side of the down-cutting blade 4. Specifically, the first screw rod 52 and the transmission shaft 55 are both cylindrical, and the connection between the two is more convenient. The square block 54 is integrally arranged with the transmission shaft 55 and cooperates with the square slot 513. On the one hand, the rotation of the first screw rod 52 is limited to a certain extent. On the other hand, the transmission shaft 55, the square block 54 and the handle 56 are transmitted through the first screw rod 52, thereby ensuring the normal and stable movement of the down-cutting blade 4.

[0062] In this embodiment, the first adjusting knob 53 is provided with a cavity, the inner wall of the cavity is provided with threads and is threadedly matched with the first screw rod 52; specifically, the working process of the first adjusting component 5 is as follows:

[0063] When the first adjusting knob 53 is turned, the first screw 52 is threadedly connected to the first adjusting knob 53. Since the first screw 52 is connected to the transmission shaft 55, the transmission shaft 55 is integrally connected to the square block 54, and the square block 54 is slidably connected to the square groove 513 to limit the rotation of the first screw 52, ​​the first screw 52 moves, driving the transmission shaft 55, the square block 54, the handle 56 and the down-cutting blade 4 to move toward the direction close to the insulated wire to extend into the annular groove. Since the first screw 52 slides in the square groove 513, the first spring 57 can ensure the compactness of the structure.

[0064] On the contrary, the first adjusting knob 53 is rotated in the reverse direction, and the first screw 52 is threadedly connected to the first adjusting knob 53. Since the first screw 52 is connected to the transmission shaft 55, the transmission shaft 55 is integrally connected to the square block 54 and is slidingly connected to the square groove 513, the rotation of the first screw 52 is restricted to a certain extent. At this time, the first screw 52 moves in the reverse direction, driving the transmission shaft 55, the square block 54, the handle 56 and the cutting blade 4 to move in a direction away from the insulated wire to move away from the annular groove.

[0065] Furthermore, the driving block 51 is provided with a viewing port 511 , and the driving block 51 is also provided with a scale 512 located directly below the viewing port 511 . The transmission shaft 55 is provided with a positioning mark 551 extending out of the viewing port 511 and matching with the scale 512 .

[0066] When adjusting, the first screw rod 52 is connected with the transmission shaft 55 and the square block 54. Therefore, when the first screw rod 52 moves, the transmission shaft 55 and the square block 54 move accordingly and drive the handle 56 and the down-cutting blade 4 to move synchronously, and also drive the positioning mark 551 on the transmission shaft 55 to move synchronously. In addition, the movement of the positioning mark 551 can be observed from the visual port 511, and then the moving distance of the blade is recorded through the scale 512, so that the cutting depth of the blade on the insulated wire can be accurately grasped to reduce the damage of the insulated wire.

[0067] Furthermore, the fixed seat 1 and the sliding seat 2 cooperate to form a receiving groove 6 located on the side of the clamping space 13 close to the rotary cutting mechanism. The rotary cutting mechanism includes a rotary cutting blade 7 arranged in the receiving groove 6 and used for circumferential cutting of the insulated wire. The rotary cutting blade 7 is connected to a second adjustment component 9 to control the circumferential cutting depth of the rotary cutting blade 7.

[0068] In this embodiment, the formation of the accommodating groove 6 ensures the safe placement of the rotary cutting blade 7. When the rotary cutting blade 7 is not in use, the rotary cutting blade 7 is located in the accommodating groove to avoid safety hazards caused by accidental injury.

[0069] Further, if Figure 5 and Figure 1 As shown, the rotary cutting blade 7 is an arc-shaped blade and is arranged obliquely in the receiving groove 6.

[0070] Specifically, the rotary cutting blade 7 is in a certain arc shape so that the blade can rotate in an annular direction with stable force. When performing annular cutting, the rotary cutting blade 7 is against the insulated wire. When the wire stripper rotates as a whole, the rotary cutting blade 7 is driven to cut in an annular direction on the insulated wire. The rotary cutting blade 7 is arranged at an angle to ensure that the force on the rotary cutting blade 7 is stable.

[0071] Further, if Figure 1 and Figure 3 As shown, a driving groove 8 is provided on the fixed seat 1, and the second adjustment component 9 includes a second screw 91 arranged in the driving groove 8, one end of the second screw 91 is threadedly connected with a second adjustment knob 93, the second screw 91 is sleeved with a second spring 92 located in the driving groove 8, and the other end of the second screw 91 is connected to a square cutter head 94, and the square cutter head 94 is connected to the rotary cutting blade 7.

[0072] Similar to the first adjusting assembly 5 , the second adjusting assembly 9 controls the movement of the rotary cutting blade 7 through the threaded cooperation of the second screw 91 and the second adjusting knob 93 .

[0073] Specifically, the second adjusting knob 93 is turned, and the second screw 91 is threadedly connected to the second adjusting knob 93. Since the second screw 91 is connected to the square cutter head 94, and the driving groove 8 is a square groove, the square cutter head 94 is slidably connected to the driving groove 8 to restrict the rotation of the second screw 91 to a certain extent. At this time, the second screw 91 moves, driving the square cutter head 94 and the rotary cutting blade 7 to move toward the direction close to the insulated wire and obliquely abut against the insulated wire, thereby adjusting the depth of the circular cutting of the rotary cutting blade 7. Since the second screw 91 slides in the driving groove 8, the second spring 92 can ensure the compactness of the structure, thereby preventing the second screw 91 from moving at will.

[0074] Rotate the second adjusting knob 93 in the reverse direction, the second screw 91 is threadedly connected to the second adjusting knob 93. Since the second screw 91 is connected to the square cutter head 94, the driving groove 8 is a square groove, the square cutter head 94 is slidingly connected to the driving groove 8 to limit the rotation of the second screw 91 to a certain extent. At this time, the second screw 91 moves in the reverse direction, driving the square cutter head 94 and the rotary cutting blade 7 to move away from the insulated wire to stop the rotary cutting work.

[0075] Example 2

[0076] The present invention also provides another embodiment, a novel wire stripping method, comprising the following steps:

[0077] S1, determine the stripping distance of the insulated wire, hold the fixed seat 1 and the sliding seat 2 with both hands to open the clamping space 13, and then let the insulated wire be clamped into the clamping space 13. When a force is applied to the sliding seat 2 in a direction away from the fixed seat 1, the third spring 32 will provide a reverse force to the sliding seat 2. When the applied force is greater than the reaction force of the elastic component 3, the sliding seat 2 will slowly move away from the fixed seat 1, so that the clamping space 13 becomes larger to facilitate the insertion of the insulated wire. After the force is cancelled, the force of the elastic component 3 causes the sliding seat 2 to reset to clamp the insulated wire.

[0078] At this time, the fixed seat 1 and the sliding seat 2 are respectively located on both sides of the insulated wire, and the fixed seat and the sliding seat are driven to rotate circumferentially around the insulated wire. At this time, the rotary cutting blade 7 is against the insulated wire, driving the rotary cutting blade 7 to cut circumferentially on the insulated wire, and the second adjusting knob 93 is turned. The second screw 91 is threadedly connected to the second adjusting knob 93. Since the second screw 91 is connected to the square cutter head 94, the driving groove 8 is a square groove, and the square cutter head 94 is slidably connected to the driving groove 8 to limit the rotation of the second screw 91 to a certain extent. At this time, the second screw 91 moves, driving the square cutter head 94 and the rotary cutting blade 7 to move in the direction close to the insulated wire and obliquely against the insulated wire, thereby adjusting the depth of the circular cutting of the rotary cutting blade 7.

[0079] Afterwards, the rotary cutting blade 7 abuts against the insulated wire, and the wire stripping pliers rotate as a whole, driving the rotary cutting blade 7 to cut the insulated wire in an annular direction. After the rotary cutting blade 7 completes the cutting, annular grooves are formed at both ends of the stripping area on the insulated wire; at this time, the thickness of the wire sheath is exposed.

[0080] S2, then readjust the position of the insulated wire entering the clamping space, drive the first adjustment component 5 to adjust the down-cutting mechanism and make the down-cutting blade 4 extend into the annular groove, drive the first adjustment component 5 to adjust the down-cutting blade 4, so that the down-cutting blade 4 moves in the direction close to the insulated wire: it can be adjusted according to the depth of the annular groove:

[0081] The first adjusting knob 53 is turned, and the first screw rod 52 is threadedly connected to the first adjusting knob 53. Since the first screw rod 52 is connected to the transmission shaft 55, the transmission shaft 55 is integrally connected to the square block 54 and is slidably connected to the square groove 513, the rotation of the first screw rod 52 is limited to a certain extent. At this time, the first screw rod 52 moves, driving the transmission shaft 55, the square block 54, the handle 56 and the down-cutting blade 4 to move toward the direction close to the insulated wire to extend into the annular groove. After that, the staff member holds the long handle 10 and the short handle 11 with both hands and pulls along the length direction of the insulated wire. The down-cutting blade 4 cuts a long cut on one side of the insulated wire, and stops pulling when it cuts to the position of another annular groove.

[0082] Since the down-cutting blade 4 is arranged at the rear side of the fixing seat 1, only the rear side of the insulated wire can be cut during transverse cutting, and the entire wire clamp is turned so that the down-cutting blade 4 is facing the front side of the insulated wire for transverse cutting. After the cutting is completed, the wire sheath of the insulated wire is directly divided into two halves, which is convenient for stripping.

[0083] S3, the wire sheath is split into two halves, the wire sheath is peeled off, and then the remaining protective thin layer is cleaned with a knife.

[0084] Example 3

[0085] Finally, the present invention also conducts the following experiment, selecting two common wire strippers on the market, the model of the ordinary pliers wire stripper is BX-30, and the model of the rotary cutting wire stripper is BXQ-Z-40B; the two wire strippers and the wire stripper of the present invention are tested for the degree of wire damage and the length of wire stripping, and the test results are shown in Table 1;

[0086] Table 1 Performance comparison of three different types

[0087]

[0088] From the above, it can be seen that the wire stripper in this embodiment can better avoid cable damage, while shortening the wire stripping time, is more convenient in operation, and has great application prospects.

[0089] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention.
