Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable stripping, in particular to a sliding cable stripping knife. BACKGROUND

[0002] In the field of power and communication, cables are often used to transmit electrical signals and optical signals, including optical cables, electrical cables, and hybrid optical and electrical cables. Most cables are designed with a layered structure, with a protective sheath layer surrounding the cable core to provide protection against fire, moisture, and pressure. However, the sheath layer is usually made of PE or modified materials containing PE, and it needs to be stripped before use.

[0003] The sheath layer is made of PE or modified materials containing PE, which is essentially a thermoplastic resin. A sharp tool can cut the sheath layer, and then it can be stripped along the cut. In actual operation, users often use common electrician knives to strip the cable sheath. However, the depth of the cut and the force of the cut cannot be controlled when using an electrician knife, which often damages the cable core. Moreover, the electrician knife requires the user to coordinate the tool with both hands, which often leads to inaccurate positioning of the knife tip and causes the cut to deviate. This can easily cause injury to the user's fingers and back of the hand.

[0004] In order to avoid the above problems, a special cable stripping device is provided for the user. For example, a Chinese patent with the publication number CN111948769A and the invention name "Optical cable stripping device" discloses an optical cable stripping structure, which includes a circularly arranged stripping support, and two stripping knife assemblies and a wire pressing mechanism symmetrically arranged along the outer circumference of the stripping support. The wire pressing mechanism tightly presses the optical cable, and then the stripping knife assembly adjusts the position of the stripping knife relative to the cable diameter to achieve stripping of the sheath layer. This stripping device seems very practical, but users rarely use it. The main reason is that the process of using this device is too complex. The end of the cable needs to be introduced into the stripping support, then the wire pressing mechanism is used to tightly press and fix the cable, and finally the stripping knife assembly is adjusted to control the position of the knife. Moreover, this device has some defects when in use. Since the cable has been tightly pressed and fixed in front of the stripping knife of the stripping knife assembly by the wire pressing mechanism, it is difficult to adjust the stripping knife to insert into the sheath layer of the cable core in actual use. Moreover, since the wire pressing mechanism has tightly pressed and fixed the cable, it is also difficult to move the cable relative to the stripping knife assembly during stripping. Therefore, the existing cable stripping device cannot achieve convenient and fast stripping, and it is not suitable. SUMMARY

[0005] To this end, the technical problem to be solved by the present application is to overcome the inconvenience of the cable stripping device in the prior art, and to provide a sliding cable stripping knife, which can independently, quickly and safely complete the cable stripping operation, is convenient for the operator to use, improves the work efficiency, and avoids the risk of the operator being cut.

[0006] To solve the above technical problem, the present application provides a sliding cable stripping knife, comprising:

[0007] A support frame has a circular arc surface that is attached to the cable, and the circular arc surface can be attached to the outer circumferential surface of the cable in the axial extension direction. A sliding groove is provided on the circular arc surface and extends along the axial direction of the cable.

[0008] A stripping knife assembly includes a sliding block that slides in the sliding groove. The sliding block partially protrudes from the support frame. A connecting piece is provided on the sliding block, and a cable stripping knife protruding from the circular arc surface is provided on the connecting piece. The cable stripping knife is rotationally arranged on the connecting piece, and rotating the cable stripping knife can adjust the length of the cable stripping knife protruding from the circular arc surface.

[0009] In an embodiment of the present application, an out-knife groove is further provided on the support frame. The out-knife groove is provided on one end surface of the support frame, and the out-knife groove is in communication with the sliding groove. When the sliding block moves to the end of the sliding groove, the connecting piece passes through the out-knife groove, and the cable stripping knife extends from the end surface of the support frame.

[0010] In an embodiment of the present application, an out-knife groove is further provided on the support frame. The out-knife groove is provided on one end surface of the support frame, and the out-knife groove is in communication with the sliding groove. When the sliding block moves to the end of the sliding groove, the connecting piece passes through the out-knife groove, and the cable stripping knife extends from the end surface of the support frame.

[0011] In an embodiment of the present application, a fixing groove is further provided on the support frame. The fixing groove is provided on the corresponding two side surfaces of the support frame.

[0012] In an embodiment of the present application, a limiting portion is provided in the sliding groove, and the sliding block has a limiting protrusion that is clamped in the limiting portion.

[0013] In an embodiment of the present application, the sliding block further has a circular arc portion that cooperates with the circular arc surface.

[0014] In an embodiment of the present application, anti-slip lines are provided on the circular arc surface.

[0015] In one embodiment of the present application, the stripping knife is rotationally connected to the connecting piece by a connecting shaft.

[0016] In one embodiment of the present application, an arc groove is formed on the connecting piece, the connecting shaft is concentrically arranged in the arc groove, and a fastener passing through the arc groove is arranged in the arc groove, the fastener being threadedly connected to the stripping knife.

[0017] In one embodiment of the present application, the blade of the stripping knife is inwardly bent.

[0018] The above technical solution of the present application has the following advantages over the prior art:

[0019] The sliding cable stripping knife comprises a support frame and a stripping knife assembly arranged on the support frame, the support frame has an arc surface capable of being attached to a cable. When the device is used, the cable is directly attached to the arc surface. As long as the support frame and the cable are gripped at the same time, extrusion force is applied to the outside of the support frame and the cable, the position of the cable can be quickly fixed, without the need to set a complex adjusting assembly and adopt a complex adjusting step. After the relative position of the support frame and the cable is fixed, the sliding block in the stripping knife assembly is only needed to be slid, and the stripping knife protruding from the arc surface can cut the sheath layer of the cable, directly realizing the stripping action of the sheath layer of the cable. The whole process saves the process of introducing the cable and clamping and fixing the cable, and can be completed in a short time of only a few seconds, which is convenient for operators to use, improves work efficiency, and avoids the risk of the operator being cut.

[0020] Moreover, the sliding cable stripping knife is arranged with a stripping knife rotationally connected to a connecting piece. The length of the stripping knife protruding from the arc surface can be adjusted according to the thickness of the sheath layer of the cable, so that the sheath layer can be cut and the cable core will not be damaged when the stripping knife cuts in.

DETAILED DESCRIPTION

[0027] The present application will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present application and implement it, but the embodiments are not as a limitation on the present application.

[0028] As described above, since the cable is a cylindrical structure, when stripping the cable, it is necessary to cut the circumference of the cable along the axial extension direction of the cable, and in the actual operation process, it is difficult to fix the position of the cable, so it is difficult to find a flat cutting surface; In order to solve this problem, it is easy to think of setting a clamping mechanism to clamp and fix the cable, and then setting a stripping knife mechanism to cut the cable sheath, but as the prior art stripping cable device described in the background, after setting the clamping mechanism, the stripping cable operation steps are very complex, which leads to low stripping cable efficiency and inconvenient use for the operator, and the technical difficulty that can be imagined is: setting the clamping mechanism to clamp and fix the cable, setting the stripping knife mechanism to cut the cable, that is, the relative position of the cable and the clamping mechanism is fixed, and the relative position of the cable and the stripping knife mechanism is sliding, which can meet the above-mentioned action requirement, obviously, the clamping mechanism and the stripping knife mechanism cannot be fixed on the same structure.

[0029] Based on the analysis of the above technical problems, referring to Figure 1 and Figure 2As shown, the present application discloses a sliding cable stripping knife, comprising: a support frame 1 and a stripping knife assembly 2 arranged on the support frame 1, wherein the support frame 1 has a circular arc surface that is in contact with the cable, and the circular arc surface can be in contact with the outer circumferential surface of the cable in the axial extension direction; when using the device, the cable is directly attached to the circular arc surface, as long as the support frame 1 and the cable are gripped at the same time, and the extrusion force is applied to the outside of the support frame 1 and the cable, the cable position can be quickly fixed, without the need to set up a complex adjusting assembly and use a complex adjusting step; a sliding groove 11 is arranged on the circular arc surface, the sliding groove 11 is arranged along the axial extension direction of the cable, the stripping knife assembly 2 comprises a sliding block 21 that can move in the sliding groove 11, a connecting piece 22 is arranged on the sliding block 21, and a cable stripping knife 23 protruding from the circular arc surface is arranged on the connecting piece 22; the sliding block 21 partially protrudes from the support frame 1 and serves as a force applying part of the sliding block 21; after the relative position of the support frame 1 and the cable is fixed, the sliding block 21 only needs to be moved along the sliding groove 11 by the force applying part, and the cable stripping knife 23 arranged on the sliding block 21 can cut open the sheath layer of the cable.

[0030] The sliding cable stripping knife of the present embodiment can directly realize the stripping action of the sheath layer of the cable, the whole process saves the process of introducing the cable and clamping and fixing the cable, and only a few seconds are needed to complete the operation, which is convenient for the operator to use and improves the work efficiency; the operator only needs to hold the support frame 1 and the cable with one hand and push the sliding block 21 with the other hand, the whole process of the cable stripping knife 23 moving inside the support frame 1 avoids the risk of the operator being cut by the cable stripping knife 23.

[0031] Moreover, the cable stripping knife is not fixedly arranged on the connecting piece 22, but is rotatably arranged on the connecting piece 22; rotating the cable stripping knife 23 can adjust the length of the cable stripping knife 23 protruding from the circular arc surface; in actual use, the length of the cable stripping knife 23 protruding from the circular arc surface can be adjusted according to the thickness of the sheath layer of the cable, so that the sheath layer can be cut open and the cable core will not be damaged when the cable stripping knife 23 cuts into the cable.

[0032] In the actual operation process, when stripping the cable, it is necessary to cut a long slit along the axial extension direction of the cable, therefore, in the present embodiment, the circular arc surface has a certain length along the axial extension direction of the cable, so that a long enough slit can be cut; moreover, in order to facilitate the operator to use and carry, the overall length of the support frame 1 should not be too long, and preferably, the length of the support frame 1 is 40-100 cm, which is best for one person to complete the clamping action and the cutting action;

[0033] Specifically, in the embodiment, the support frame 1 is arranged in a rectangular structure, the support frame 1 is arranged in a hexahedral structure, the support frame 1 comprises not only the arc surface capable of being attached to the cable but also the top surface corresponding to the arc surface, the two corresponding end surfaces arranged between the arc surface and the top surface, and the two corresponding side surfaces.

[0034] In the embodiment, on one hand, the support frame 1 and the cable need to be held at the same time, that is, the support frame 1 needs to be provided with a grabbing part for convenient grabbing, and on the other hand, in order to facilitate the pushing of the sliding block 21, the sliding block 21 needs to partially protrude from the support frame 1, that is, a through hole capable of leading out the sliding block 21 also needs to be arranged on the support frame 1, and therefore, when the positions of the grabbing part and the through hole are arranged, the use situation and the operation habit need to be combined to make a reasonable layout.

[0035] In the operation process, generally, the user holds the cable with one hand, places the cable in the palm, buckles the arc surface of the support frame 1 above the cable, and places the thumb and the four fingers on the two sides of the support frame 1, and therefore, the best position of the grabbing part should be on the two corresponding side surfaces of the support frame 1, as shown in Figure 2 In the embodiment, the fixing groove 12 is further arranged on the support frame 1, the fixing groove 12 is arranged on the two corresponding side surfaces of the support frame 1, and when the support frame 1 and the cable are held, the thumb and the remaining four fingers are respectively inserted into the two fixing grooves 12.

[0036] In the embodiment, the fixing groove 12 has the advantages that not only the grabbing is convenient, but also the fixing groove 12 can be directly clamped and fixed by using a bolt and a clamping assembly, and the stripping knife can be arranged on a fixed production line to be suitable for more application scenarios; in other embodiments, if only the grabbing is convenient, the grabbing part can also be arranged in a finger-imitating profile structure.

[0037] Specifically, the support frame 1 has four side surfaces in the axial extension direction of the cable, one side surface is used as the arc surface attached to the cable, the two side surfaces on the two sides of the arc surface are provided with the grabbing part, and therefore, only the top surface corresponding to the arc surface has space for the partial protrusion of the sliding block 21, as shown in Figure 1 In the embodiment, the rod outlet groove 13 is further arranged on the support frame 1, the rod outlet groove 13 is arranged on the top surface of the support frame 1 corresponding to the arc surface, the rod outlet groove 13 is in communication with the sliding groove 11, the extension direction of the rod outlet groove 13 is the same as that of the sliding groove 11, and the sliding block 21 has the handle 211 partially protruding from the rod outlet groove 13.

[0038] Specifically, the width of the out-bar slot 13 is slightly larger than the width of the grip bar 211, the grip bar 211 slides in the out-bar slot 13, and the sliding direction of the grip bar 211 is limited by the out-bar slot 13; the length of the grip bar 211 is about 10 cm, which facilitates the user to hold the grip bar 211 and apply enough force to push the sliding block 21.

[0039] Specifically, in this embodiment, the sliding block 21 needs to be able to slide in the sliding slot 11, and the sliding block 21 also needs to be prevented from being detached from the sliding slot 11, therefore, a limiting portion is arranged in the sliding slot 11 along the extension direction of the sliding slot 11, as shown in Figure 4 The sliding block 21 has a limiting protrusion 212 that is clamped in the limiting portion, through the cooperation of the limiting portion and the limiting protrusion 212, the movement of the sliding block 21 in the sliding slot 11 is not affected, and the sliding block 21 is also prevented from being detached from the sliding slot 11, at the same time, the tilting direction of the sliding block 21 is also limited, so that when the grip bar 211 on the top surface of the sliding block 21 applies a pushing force, the sliding block 21 moves horizontally along the sliding slot 11, rather than tilting in the sliding slot 11.

[0040] Specifically, when the above sliding cable stripping tool is actually used, there is still a problem, which is also mentioned in the prior cable stripping device in the background art, that is, at the initial position, if the cable stripping knife 23 is protrudingly arranged on the arc surface, in the actual use process, a very large force needs to be applied to make the cable stripping knife 23 radially inserted into the sheath layer of the cable, so that the arc surface is attached to the cable, which is difficult to use in the actual operation process.

[0041] In order to solve this problem, as shown in Figure 3 In this embodiment, an out-knife slot 14 is further arranged on the support frame 1, the out-knife slot 14 is arranged on one end surface of the support frame 1, the out-knife slot 14 is in communication with the sliding slot 11, when the sliding block 21 moves to the end of the sliding slot 11, the connecting piece 22 passes through the out-knife slot 14, and the cable stripping knife 23 extends out of the end surface of the support frame 1, so that in the actual operation process, the sliding block 21 is first slid to the end of the sliding slot 11, and the cable stripping knife 23 extends out of the out-knife slot 14, so that there is no protruding cable stripping knife 23 on the arc surface, the support frame 1 is buckled on the end of the cable, at this time, the cable stripping knife 23 is arranged on the side surface of the cable, and the sliding block 21 drives the cable stripping knife 23 to cut the sheath layer from the side surface of the cable cross section, so that the support frame 1 and the cable do not need to apply a very large force, and the side cutting method is easier to achieve than the direct insertion method.

[0042] Specifically, after adopting the above structure, the blade of the cable stripping knife 23 is inwardly bent, and the protruding side of the cable stripping knife 23 is a blunt surface, so that the user will not be scratched, and the use of the cable stripping knife of the embodiment is safer.

[0043] Referring to Figure 4 In the embodiment, the arc surface is completely fitted with the cable, and since the sliding block 21 also slides on the arc surface, the sliding block 21 is also provided with an arc part that is fitted with the cable, the arc part has the same radius of curvature as the arc surface, and the arc part is a part of the arc surface.

[0044] Specifically, the arc surface is fitted with the cable, and the relative position between the support frame 1 and the cable needs to be fixed by the friction between the arc surface and the cable, the arc part is fitted with the cable, and the arc surface needs to be able to slide relative to the cable, so in the embodiment, the arc surface is a friction surface, the arc surface is provided with anti-skid lines that increase the friction, the arc part is a smooth surface, and the friction between the arc part and the cable is minimized.

[0045] Referring to Figure 4 In the embodiment, in order to enable the cable stripping knife 23 to rotate relative to the connecting piece 22, the cable stripping knife 23 and the connecting piece 22 are rotationally connected through a connecting shaft 24, the connecting shaft 24 respectively penetrates the connecting piece 22 and the cable stripping knife 23, and adjusting the connecting shaft 24 can control the rotation of the cable stripping knife 23.

[0046] Specifically, after adjusting the angle of the cable stripping knife 23, the relative position between the cable stripping knife 23 and the connecting piece 22 needs to be fixed, in the embodiment, an arc slot 221 is formed in the connecting piece 22, the arc slot 221 is concentrically arranged with the connecting shaft 24, a fastener 25 that penetrates the arc slot 221 is arranged in the arc slot 221, the fastener 25 is threadedly connected to the cable stripping knife, when the cable stripping knife 23 is adjusted, the fastener 25 is loosened, so that the cable stripping knife 23 can rotate relative to the connecting piece 22, and after the position of the cable stripping knife is adjusted, the fastener 25 is tightened, so that the relative position between the cable stripping knife 23 and the connecting piece 22 is fixed.

[0047] Specifically, in the embodiment, in order to realize visual adjustment, a scale line is further arranged on the side surface of the arc slot 221, when the cable stripping knife 23 is adjusted, the length of the protruding arc surface of the cable stripping knife 23 can be determined according to the locking position of the fastener 25, so that the cable stripping knife 23 can be directly adjusted to a suitable position according to the thickness of the cable sheath, and accurate cutting of the sheath layer is ensured.

[0048] Obviously, the above embodiments are merely example for clearly illustrating, and are not limitation to the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments are not required to be enumerated, and the obvious changes or variations derived from the above are still within the protection scope of the present application.
