Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric power tools, in particular to a bundled cable connecting rib breaking device. BACKGROUND

[0002] With the rapid development of communication and power industry, bundled cables are widely used in low-voltage overhead lines due to their compact structure and convenient laying. The bundled cable is composed of multiple parallel insulated cores and integrated by the outer connecting rib. When installing the wiring, the connecting rib between the cores must be broken to separate the cores.

[0003] At present, the industry generally uses a Swiss knife or other handheld cutters to break the connecting rib. However, the cutting process of the Swiss knife is controlled by the operator's hand feeling and experience. Since the hand force is difficult to maintain constant, uneven force is prone to occur. If the force is too light, the connecting rib may not be completely cut through, and repeated cutting is required. If the force is too heavy, the connecting rib may be cut too deep, resulting in direct cutting of the insulating layer or internal core of the cable below. In addition, when manually pushing the Swiss knife to cut, the hand is easily affected by changes in operating posture or slight shaking, making it difficult to ensure a straight cutting path, and the cutting path may deviate, resulting in uneven cutting surface and even damage to the cable insulating layer and internal core.

DETAILED DESCRIPTION

[0034] The specific embodiments of the present application are described in further detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.

[0035] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second" and the like are used to describe various information in the present application, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, the "first" information can also be referred to as "second" information, and similarly, the "second" information can also be referred to as "first" information without departing from the scope of the present application.

[0036] As Figures 1 to 5 shown, and with reference to the orientation shown in Figure 1 , a bundled cable connecting rib breaking device according to an embodiment of the present application comprises a shell 1, a guide rod 2, a support 3, a guide block 5 and a linear drive mechanism.

[0037] The shell 1 is integrally cast with PVC material, has high strength, high insulation performance, oil stain resistance, and is suitable for various low-voltage operating environments. The shell 1 comprises a receiving groove 11 and a fixed handle 14, the groove depth direction of the receiving groove 11 extends along the left and right, the receiving groove 11 has an opening towards the left or right side, and the receiving groove 11 is used to accommodate the bundled cable 9. The fixed handle 14 is located at the lower end of the side of the shell 1 away from the opening of the receiving groove 11, and the fixed handle 14 extends upward and downward, and the fixed handle 14 is used to provide a stable gripping fulcrum.

[0038] The inside of the shell 1 has two fixed holes 15, the two fixed holes 15 are opposite to each other, one end of the guide rod 2 is fixed in one of the fixed holes 15, and the other end of the guide rod 2 is fixed in the other fixed hole 15.

[0039] The support 3 is arranged in the shell 1, and the front end of the support 3 is fixedly installed with a blade 4, and the rear end of the support 3 is provided with a through hole, which is sleeved on the guide rod 2, so that the support 3 can move along the length direction of the guide rod 2 and rotate around the guide rod 2.

[0040] The guide block 5 is movably assembled in the shell 1, and the first elastic member 51 is connected between the guide block 5 and the support 3, and the first elastic member 51 is a spring.

[0041] An adjusting screw 6 is arranged on the guide block 5 in the up-down direction, when the adjusting screw 6 moves downward, the lower end of the adjusting screw 6 pushes the support 3 to rotate around the guide rod 2, so that the blade 4 moves downward and extends into the accommodating groove 11 to cut the connecting rib. By rotating the adjusting screw 6, the falling depth of the blade 4 can be accurately controlled, so that the cutting strength can be accurately controlled. The first elastic member 51 is used to apply an elastic force to the support 3, so that after the adjusting screw 6 moves upward and resets, the support 3 can reversely rotate around the guide rod 2 to drive the blade 4 to move upward and reset.

[0042] A linear driving mechanism is arranged on the shell 1, and the linear driving mechanism is used to drive the shell 1 to move forward and backward, so that the blade 4 cuts the connecting rib.

[0043] Specifically, the linear driving mechanism can be a manually driven gear and rack mechanism, a lead screw and nut mechanism, or an electrically driven lead screw and nut mechanism, a synchronous belt mechanism, or any mechanism that can realize the linear movement of the shell 1.

[0044] It should be noted that after the cutting strength is set by using the adjusting screw 6 and the connecting rib is broken at a single point, the shell 1 is driven to move forward and backward by using the linear driving mechanism, so that the blade 4 moves along the linear path at the preset cutting strength to break the connecting rib along the length direction of the cable. In this way, the cutting strength during the cutting process is constant, and the preset cutting strength is always maintained, so that the connecting rib is not broken due to too light strength, and the insulating layer or the internal wire core is not cut too deeply due to too heavy strength. In addition, the cutting path during the cutting process is forcibly constrained, so that the cutting path is strictly parallel to the length direction of the cable, the cutting surface is smooth, and the damage to the insulating layer and the internal wire core caused by the path deviation is avoided. In addition, the operator does not need rich experience and superb touch, only needs to simply rotate the adjusting screw 6 to set the cutting strength, and then starts the linear driving mechanism to complete the operation, and the blade 4 is always hidden in the shell 1 and is not exposed to the operation environment, so that the risk of the blade 4 hurting people is avoided, and the safety and reliability of the wiring operation are greatly improved.

[0045] In some embodiments of the present application, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 and Figure 9 , the linear driving mechanism is located below the accommodating groove 11, and the linear driving mechanism includes a movable handle 71 and a friction wheel 74.

[0046] The movable handle 71 is made of PVC material and has anti-skid lines on the outer surface, high insulation performance, high strength and anti-skid characteristics. The upper end of the movable handle 71 is provided with a driving gear 72, which is an incomplete gear. The driving gear 72 is rotatably installed in the shell 1 and is located at the rear side of the fixed handle 14 and spaced apart from the fixed handle 14. The operator can operate with one hand, hold the fixed handle 14 and the movable handle 71 with one hand, and pinch the movable handle 71 with fingers to move it towards the fixed handle 14. The operator can also operate with both hands, hold the fixed handle 14 with one hand and move the movable handle 71 with the other hand, so that the movable handle 71 drives the driving gear 72 to rotate.

[0047] The second elastic member 73 is connected between the movable handle 71 and the shell 1, and is a spring. The second elastic member 73 is used to apply an elastic force to the movable handle 71, so that the movable handle 71 has a swing tendency away from the fixed handle 14. After the operator releases the movable handle 71, the movable handle 71 can swing back to the original position.

[0048] The friction wheel 74 is rotatably installed in the shell 1 around the left and right extending axis, and the upper surface of the friction wheel 74 is used to abut the lower surface of the bundled cable 9. The outer surface of the friction wheel 74 is treated by sanding process to enhance the friction force, so as to ensure that the friction wheel 74 and the bundled cable 9 will not slip. The end of the friction wheel 74 close to the driving gear 72 is provided with a transmission wheel 75, the transmission wheel 75 is elastically installed with a one-way tooth 751, and the transmission wheel 75 is rotatably sleeved with a driven gear 76. The driven gear 76 has an inner tooth portion on the inner side, which is used to push the one-way tooth 751. The outer side of the driven gear 76 has an outer tooth portion, which is used to engage the driving gear 72.

[0049] Need to be explained, after setting the cutting force with the adjusting screw 6 and breaking the connecting rib at one point, the operator moves the movable handle 71, the movable handle 71 drives the driving gear 72 to rotate, the driving gear 72 drives the driven gear 76 to rotate through engagement, when the driven gear 76 rotates, the inner tooth portion pushes the one-way tooth 751, so as to transmit power to the transmission wheel 75, the transmission wheel 75 directly drives the friction wheel 74 to rotate, the upper surface of the friction wheel 74 abuts the lower surface of the bundled cable 9, and the friction force between the upper surface and the lower surface of the bundled cable 9 drives the device to move forward and backward. In addition, through the cooperation of the one-way tooth 751 and the driven gear 76, the one-way transmission effect is realized, that is, when the driving gear 72 rotates forward, it drives the friction wheel 74 to rotate, and when it reverses, it does not drive the friction wheel 74 to reverse. Even if the movable handle 71 is released during cutting, the friction wheel 74 will not retreat due to the reaction force of the cable, which ensures that the blade 4 always feeds along a straight line and avoids path deviation.

[0050] In the prior art, when the operator is working with a hand-held utility knife at a high altitude, the operator needs to manually push the utility knife to cut the connecting rib laterally in front of the operator relative to the operator. If the pushing amplitude is too small, the cutting distance is short and needs to be broken multiple times. If the pushing amplitude is too large, it is easy to cause the operator's center of gravity to be unstable and even fall from a high altitude and other operation hazards. The bundled cable connecting rib breaking device in the embodiment of the application converts the palm pressure into a cutting force through gear transmission and the design of the one-way tooth 751, replaces the lateral force cutting mode, can realize breaking of connecting ribs of any length, avoids multiple cutting, greatly shortens the working time, improves the working efficiency, can effectively maintain the stability of the operator's center of gravity, reduces the possibility of dangerous operation, and improves the safety of wiring operation.

[0051] In some embodiments of the application, as shown in Figure 2 、 Figure 5 and Figure 7 , the bottom of the support piece 3 is provided with a guide block 31, the guide block 31 is arranged close to the blade 4, the guide block 31 gradually decreases from the upper end to the lower end, the width of the lower end of the guide block 31 is equal to the width of the connecting rib, and the guide block 31 is used to extend into the adjacent two cables and abut against the connecting rib. When the adjusting screw 6 moves downward to push the support piece 3 to rotate around the guide rod 2, the lower end of the guide block 31 is first inserted between the adjacent two cables. Since the width of the guide block 31 is just matched with the width of the connecting rib, the guide block 31 can naturally slide into and be clamped above the connecting rib, automatically centering with the connecting rib, and at the same time driving the support piece 3 and the blade 4 to move left and right. The cutting position of the blade 4 when falling is limited to be above the connecting rib, so that the operator does not need to accurately judge the position of the connecting rib by naked eyes, the human error of the starting point is eliminated, and it is ensured that each cutting starts from the most correct position and is along the most straight path, so that the cutting quality is highly consistent.

[0052] In some embodiments of the application, as shown in Figure 2 、 Figure 3 and Figure 5 , the left and right sides of the support piece 3 are symmetrically provided with a positioning rotating wheel 8, the positioning rotating wheel 8 is located between the guide block 31 and the through hole, and the lower end of the positioning rotating wheel 8 is used to abut against the cables on both sides of the connecting rib.

[0053] The positioning rotating wheel 8 is located above the accommodating groove 11 and is pressed tightly against the upper surface of the cable through the cutting force and the gravity of the support piece 3 conducted by the adjusting screw 6, so as to form a stable pressing force. The pressing force forces the cable to be pressed towards the friction wheel 74 below, so as to ensure that the upper surface of the friction wheel 74 is tightly combined with the lower surface of the cable, and avoids the friction failure caused by the gap.

[0054] In addition, the guide block 31 and the two positioning rollers 8 form a stable support structure through three-point cooperation, which ensures that the blade 4 always acts vertically on the connecting rib and the cutting depth is uniform. The positioning roller 8 can roll along the surface of the cable, which not only reduces the friction damage to the cable insulation layer but also reduces the overall moving resistance, making the cutting feeding more stable and labor-saving.

[0055] As shown in some embodiments of the present application, Figures 5 to 7 The support 3 is provided with an axle hole 34, and the hole length direction of the axle hole 34 extends upward and downward. The inner bottom surface of the axle hole 34 is placed with a rotating shaft 81 extending left and right, one positioning roller 8 is installed at the left end of the rotating shaft 81, and the other positioning roller 8 is installed at the right end of the rotating shaft 81. A spring 82 is arranged between the support 3 and the rotating shaft 81, the lower surface of the spring 82 is attached to the upper surface of the rotating shaft 81, which is used to apply an elastic force to the rotating shaft 81 to press the rotating shaft 81 tightly downward, so as to stabilize the positioning of the rotating shaft 81 and ensure that the lower end of the positioning roller 8 presses the cable on both sides of the connecting rib. The spring 82 is made of metal and has a smooth surface, which reduces the friction coefficient and improves the smoothness of the rotation of the positioning roller 8, and at the same time has the ability of elastic deformation, which can adapt to cables of different diameters.

[0056] As shown in some embodiments of the present application, Figure 1 and Figure 2 The upper surface of the shell 1 is provided with an observation port 13, the observation port 13 is communicated with the accommodating groove 11, the observation port 13 extends left and right, and at least part of the observation port 13 is opposite to the positioning roller 8 upward and downward. The observation port 13 provides a top-down view, and the operator can directly observe the placement state of the bundled cable 9 in the accommodating groove 11, and roughly judge the position of the support 3 in the left-right direction through the observation port 13, so as to adjust the position of the support 3 and the blade 4 in the left-right direction, so that the blade 4 can be moved to any connecting rib.

[0057] As shown in some embodiments of the present application, Figures 1 to 3 The guide block 5 is provided with a threaded hole, the adjusting screw 6 has a threaded part, the threaded part is screwed with the threaded hole, the upper end of the adjusting screw 6 penetrates out of the shell 1, and the upper end of the adjusting screw 6 is provided with a knob 61, which is convenient for the operator to rotate the knob 61 with fingers, so as to accurately control the advance and retreat of the adjusting screw 6.

[0058] As shown in some embodiments of the present application, Figure 4 and Figure 5 The shell 1 is provided with a sliding groove 12 extending in the groove length direction left and right, and the front and back sides of the upper end of the guide block 5 are symmetrically provided with limiting ears 52, which are movably assembled in the sliding groove 12, so as to provide accurate movement guide for the guide block 5 and ensure that the guide block 5 can only move strictly in the left-right direction.

[0059] The left and right sides of the lower end of the guide block 5 are symmetrically provided with protruding portions 53, and a groove is formed between the two protruding portions 53, and the support member 3 is at least partially inserted into the groove, so that when the operator moves the guide block 5 left and right by rotating the knob 61 or adjusting the screw rod 6, the support member 3 and the blade 4 move left and right synchronously with the guide block 5, thereby adjusting the position of the blade 4 in the left-right direction, so that the blade 4 can be moved to any connecting rib.

[0060] As shown in Figure 3 and Figure 7 The bundle cable connecting rib breaking device further comprises a fixing block 41 and a fastener 42. The support member 3 is provided with a fixing groove 33, and the groove bottom of the fixing groove 33 is provided with a blade groove 32. The front end of the blade groove 32 has a notch, and the blade 4 is installed in the blade groove 32 and partially extends out of the notch.

[0061] The fixing block 41 is installed in the fixing groove 33 and abuts against the blade 4. The fastener 42 is a screw, which passes through the perforation on the fixing block 41 and is screwed with the threaded hole on the support member 3. The fastener 42 fixedly connects the fixing block 41 and the support member 3, so that the fixing block 41 presses the blade 4 tightly.

[0062] When replacing the blade 4, only the fastener 42 needs to be loosened, the fixing block 41 is removed, and the old blade 4 can be taken out. After replacing the new blade 4, the fixing block 41 is pressed tightly, and the fastener 42 is installed.

[0063] As shown in Figure 5 The first elastic member 51 is provided with two, which are symmetrically distributed on the left and right sides of the support member 3. The two first elastic members 51 can simultaneously and equally release elastic force, and jointly act on the support member 3 to make it reset stably and accurately.

[0064] In summary, the bundle cable connecting rib breaking device provided by the embodiment of the present application uses the adjusting screw 6 to set the cutting force, breaks the connecting rib at a single point, and then uses the linear driving mechanism to drive the shell 1 to move forward and backward, so that the blade 4 moves along a straight line at the preset cutting force and breaks the connecting rib along the length direction of the cable. In this way, the cutting force during the cutting process is constant, and the preset cutting force is always maintained. The connecting rib will not be cut through due to insufficient force, and the insulating layer or the internal wire core will not be cut too deeply due to excessive force. The cutting path during the cutting process is also forcedly constrained, the cutting path is strictly parallel to the length direction of the cable, the cutting surface is smooth, and the damage to the insulating layer and the internal wire core caused by path deviation is avoided. In addition, the operator does not need rich experience and superb touch. The operator only needs to rotate the adjusting screw 6 to set the cutting force and then start the linear driving mechanism to complete the work. The blade 4 is always hidden inside the shell 1 and is not exposed to the working environment, so the risk of injury caused by the blade 4 is avoided, and the safety and reliability of the wiring work are greatly improved.

[0065] The above only describes the preferred embodiments of the present application. It should be noted that those skilled in the art can make several improvements and replacements without departing from the technical principles of the present application. These improvements and replacements should also be considered within the protection scope of the present application.
