[0030] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] The present invention will be further described in detail below through specific implementation examples in conjunction with the accompanying drawings.

[0032] The utility model embodiment provides a wire bending tool, see Figure 1The cross-sectional structure diagram of a wire bending tool when no wire bending is performed is shown, and the wire bending tool comprises: a mounting plate, a rotating component 2, a rotating handle 3 and a lever handle 4; wherein, the mounting plate is mounted with a first position limiting component 1; the rotating component 2 is rotationally connected to the mounting plate, and one end of the rotating component 2 is used to drive the cable to be wound around the first position limiting component 1; the rotating handle 3 is rotationally connected to the mounting plate, and is transmission-connected to the rotating component 2, and is used to drive the rotating component 2 to rotate; the lever handle 4 is mounted on the mounting plate, and is used to provide a lever point.

[0033] When the wire bending tool provided by the utility model is used, the rotating component, the rotating handle and the lever handle are all installed on the mounting plate, and the whole constitutes the wire bending tool. Figure 1 As shown, place the cable (for example, the cable core) between the rotating component and the first stopper, and hold the rotating handle and the lever handle tightly at the same time. The rotating handle drives the rotating component to rotate, and the lever handle provides a lever point, see FIG. Figure 2 The cross-sectional structure diagram of a wire bending tool shown in the figure is when completing wire bending. Specifically, the rotating component pushes the cable to wrap around the first limit member to complete the bending of the cable. In the process of pressing and turning the handle, the lever point provided by the lever handle is used to reduce the effort in using the wire bending tool, ensure the wire bending efficiency, and reduce the burden on personnel when using the wire bending tool to bend the wire.

[0034] In the embodiment of the utility model, the rotating end of the rotating component 2 has a cylindrical structure, the rotating end of the rotating handle 3 has a cylindrical structure, and the side surface of the cylindrical structure of the rotating component 2 is connected to the side surface of the cylindrical structure of the rotating handle 3 by a transmission belt. Specifically, the side surface of the cylindrical structure of the rotating end of the rotating component 2 is connected to the side surface of the cylindrical structure of the rotating end of the rotating handle 3 by a transmission belt. When the rotating handle 3 is operated, the transmission belt drives the rotating component 2 to rotate, and the rotating component 2 pushes the cable to wrap around the first limit member 1 to complete the bending of the cable. The rotating component 2 and the rotating handle 3 are connected by the transmission belt, which ensures smooth transmission between the two and ensures transmission efficiency, so that the rotation of the rotating handle 3 can drive the rotating component 2 to rotate.

[0035] In the embodiment of the utility model, in addition to the above structure, the rotating component 2 can also adopt other structures. For example, the rotating end of the rotating component 2 is provided with a gear structure, and the rotating end of the rotating handle 3 is provided with a gear structure meshing with the rotating end of the rotating component 2; for details, see Figure 3A schematic diagram of the second-layer structure of a wire bending tool is shown, wherein a hole is provided at the center of the rotating end of the rotating handle 3 and the rotating part 2 for fixing the installation shaft (not shown in the figure) to be rotatably connected to the mounting plate, and at the same time, a gear structure is provided on the edge of the rotating end of the rotating handle 3 and the rotating part 2, and the gear structures therebetween are meshed with each other, and the transmission connection between the rotating handle 3 and the rotating part 2 is ensured by gear meshing, thereby ensuring high efficiency and stability during transmission, and a pair of mounting holes is provided at the end of the rotating part 2 that contacts the cable for installing the wire bending member 7.

[0036] In the embodiment of the utility model, the mounting plate includes: a first mounting plate 5 and a second mounting plate 6; the first mounting plate 5 is fixedly connected to the second mounting plate 6, the rotating component 2 and the rotating handle 3 are both rotatably connected between the first mounting plate 5 and the second mounting plate 6, and the second mounting plate 6 has a rotating groove for the rotating component 2 to pass through; for details, see Figure 4 A schematic diagram of the first layer structure of a wire bending tool is shown, wherein the first mounting plate 5 is a rectangular structure, and four through holes are respectively provided at the four corners for connecting other components of the wire bending tool, and two through holes and three mounting holes are provided at the center of the first mounting plate 5. Of the two through holes, the through hole on the upper side is used to connect the rotating handle 3, and the through hole on the lower side is used to connect the rotating component 2. The three mounting holes are arranged in a triangle for connecting the lever handle 4;

[0037] See Figure 5 The third-layer structural schematic diagram of a wire bending tool shown is specifically a structural diagram of a second mounting plate 6, wherein the second mounting plate 6 has an arc-shaped rotating groove for the rotating part 2 to pass through, and a pair of parallel mounting holes are provided on the second mounting plate 6 at the end of the arc-shaped rotating groove for installing the second limit member 8, and a through hole is provided at the upper right, upper left and lower left of the second mounting plate 6 respectively for connecting to the first mounting plate 5, and two through holes are also provided in the middle part of the second mounting plate 6, which correspond to the rotating part 2 and the rotating handle 3 respectively, and a pair of parallel mounting holes are provided on the right side of the through hole for connecting the rotating part 2 for installing the first limit member 1.

[0038] In the embodiment of the utility model, the lever handle 4 is fixedly connected between the first mounting plate 5 and the second mounting plate 6; Figure 3 As shown, the lever handle 4 can be mounted to the first mounting plate 5 by means of screws. The fixedly connected lever handle 4 makes it easier for the user to use levers.

[0039] In the embodiment of the utility model, the first limit member 1 is installed on the second mounting plate 6, see Figure 6 As shown in the fourth structural diagram of a wire bending tool, the first limit member 1 can be installed to a pair of mounting holes in the middle part of the second mounting plate 6 by screws.

[0040] In the embodiment of the utility model, a bending member 7 is provided on the end of the rotating member 2 that contacts the cable. Figure 6 As shown, the bending wire member 7 can be mounted to the mounting hole of the rotating component 2 by means of screws.

[0041] In the embodiment of the utility model, a second stopper 8 is also included. The second stopper 8 is fixedly mounted on the second mounting plate 6 and is located at the end of the rotation groove of the second mounting plate 6. The second stopper 8 has a groove structure adapted to the bending member 7. The bending member drives the cable to move to the groove of the second stopper 8 and stop, so as to avoid excessive bending of the cable. Figure 6 As shown, the second limiting member 8 can be installed to the mounting hole next to the end of the rotation groove of the second mounting plate 6 by means of screws, and the groove of the second limiting member 8 faces one side of the arc-shaped rotation groove of the second mounting plate 6.

[0042] In the embodiment of the utility model, Figure 6 As shown, the bending member 7 is a semi-cylindrical structure, and the first limiting member 1 is a cylindrical structure. The arrangement of the cylindrical structure and the semi-cylindrical structure helps to form an S-shaped bending line with an arc during the final bending, ensuring the beauty of the bending line.

[0043] In the embodiment of the utility model, a pressure-proof frame 9 with a side opening is further provided between the first mounting plate 5 and the second mounting plate 6. The opening of the pressure-proof frame 9 is used for the handle end of the rotating handle 3 and the handle end of the lever handle 4 to pass through, and can ensure that the handle end of the rotating handle 3 moves. Figure 3 As shown, the anti-pressure frame 9 has an open structure, which ensures that the rotating handle 3 and the lever handle 4 extend outside the mounting plate and can ensure that the rotating handle 3 rotates within a certain range, thereby preventing the mounting plate from squeezing the handle and the rotating component 2. At the same time, through holes are provided at the lower right, upper right and upper left of the anti-pressure frame 9 for connecting between the first mounting plate 5 and the second mounting plate 6.

[0044] In the embodiment of the utility model, the wire bending tool provided has fewer components, lower processing difficulty, lower construction cost, and lower overall cost of the wire bending tool. The wire bending tool is easy to operate during use. Only by pressing the handle, a person can use the wire bending tool to complete the bending of the cable core. Generally, the wire bending tool is used to bend the cable core. It can be formed by pressing once without the assistance of other tools. The cable core after bending can be directly connected to the terminal block without manual correction.

[0045] The working principle or use method of the embodiment of the utility model is further explained below with reference to a specific example:

[0046] In this example, the first mounting plate 5 and the second mounting plate 6 of the provided wire bending tool are connected through a through hole, and a rotating handle 3, a rotating part 2 and an anti-pressure frame are rotatably connected between the first mounting plate 5 and the second mounting plate 6 through the through holes, and a lever handle 4 is installed by screws, and a first limit member 1 and a second limit member 8 are installed on the second mounting plate 6 by screws, and a wire bending member 7 is installed on the rotating part 2.

[0047] In this example, three personnel respectively bent four cable cores without using the bending tool provided in this example, and recorded the time consumed by each person for bending different cable cores, thereby obtaining the following Table 1. Table 1 Time consumed by the personnel for bending the cable core without using the bending tool provided in this example

[0048]

[0049] As shown in Table 1, the average time taken by person 1 to bend the wires four times was 28 seconds, the average time taken by person 2 to bend the wires four times was 47 seconds, the average time taken by person 3 to bend the wires four times was 55 seconds, the average time taken by the three persons to bend the wires for the first cable core was 46 seconds, the average time taken by the three persons to bend the wires for the second cable core was 43 seconds, the average time taken by the three persons to bend the wires for the third cable core was 42 seconds, the average time taken by the three persons to bend the wires for the fourth cable core was 42 seconds, and the overall average time taken by the three persons to bend the four cable cores was 43 seconds. It can be concluded that the average time taken by the persons to bend the wires without using bending tools is longer, and the wiring efficiency is lower.

[0050] In this example, see Figure 7 In the prior art shown, a schematic diagram of bending a wire when a wire bending tool is not used is shown. When a person manually bends the wire and connects it to a terminal block, the final result of the bending is messy and non-standard, and it is difficult to meet the bending requirements.

[0051] In this example, the same three people used the bending tool provided in this example to bend the cable core respectively. The time consumed by each person in bending the cable core was recorded and compared with the average time consumed in Table 1, and the following Table 2 was obtained.

[0052] Table 2 Comparison of the time spent by personnel after using the wire bending tools provided in this example

[0053] personnel Time before using the tool / second Time after using the tool / seconds Time saved / seconds Person 1 28 13 15 Person 2 47 14 33 Person 3 55 21 34 Average time 43 16 27

[0054] As shown in Table 2, the average time consumed by person 1 before using the wire bending tool was 28 seconds, and the time consumed after using the wire bending tool was 13 seconds, and the wire bending time was reduced by 15 seconds; the average time consumed by person 2 before using the wire bending tool was 47 seconds, and the time consumed after using the wire bending tool was 14 seconds, and the wire bending time was reduced by 33 seconds; the average time consumed by person 3 before using the wire bending tool was 55 seconds, and the time consumed after using the wire bending tool was 21 seconds, and the wire bending time was reduced by 34 seconds; the average time consumed by the three persons as a whole before using the wire bending tool was 43 seconds, and the overall time consumed after using the wire bending tool was 16 seconds, and the wire bending time was reduced by 27 seconds; This proves that the use of the wire bending tool provided in this example greatly reduces the wire bending time and improves the wiring efficiency.

[0055] In this example, see Figure 8 In the prior art shown, a schematic diagram of bending wires using a bending tool is provided, wherein when personnel use the bending tool provided in this example to bend wires and connect them to the terminal block, they can bend the cable core well, and the bending results are standard and beautiful, and can easily meet the bending requirements.
