Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, and in particular to a device for conveniently adjusting the tension of electric wires. Background Technology

[0002] Wire tension refers to the force acting on a wire that causes it to stretch. During the installation, laying, and use of wires, tension has many significances and impacts. Appropriate tension ensures that the wire maintains a certain degree of tightness, preventing it from becoming entangled or rubbing against other objects due to slackness, or from drooping too low and causing safety hazards. Accurate measurement, monitoring, and control of wire tension play a crucial role in ensuring the safe and reliable operation of the power system and the quality and performance of various wire-related projects and products.

[0003] A search revealed Chinese Patent Publication No. CN211239249U, which discloses a device for adjusting wire tension. Addressing the problem that existing support frames only use insulators for support and lack suitable adjustment devices for wire tension, thus failing to meet usage requirements, the following solution is proposed: It includes a mounting plate, with an insulator and an adjustment plate fixedly connected to its top. The same wire is connected to both the insulator and the adjustment plate. Two guide wheels are symmetrically rotatably mounted on the adjustment plate, and an adjustment wheel is slidably mounted on one side of the adjustment plate, positioned between the two guide wheels. The wire is connected to the two guide wheels and the adjustment wheel via a transmission connection. A groove is formed on the top of the mounting plate, within which a cylinder is rotatably mounted. A screw is threaded onto the cylinder, and the screw is adapted to the adjustment wheel. This invention not only supports the wire but also facilitates easy adjustment of wire tension, meeting usage requirements. However, it cannot effectively adjust the tension of wires of different specifications. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a device for conveniently adjusting the tension of wires, aiming to improve the problem that the existing technology cannot effectively adjust the tension of wires of different specifications.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a device for conveniently adjusting wire tension, comprising a body, a motor mounted on the outside of the body, a rotating shaft fixedly connected to the output end of the motor, a metal gear one fixedly connected to the outside of the rotating shaft, longitudinal racks provided on both the front and rear sides of the metal gear one, the metal gear one meshing with the longitudinal racks, a metal gear two fixedly connected to the left end of the rotating shaft, transverse racks provided on both the upper and lower outer sides of the metal gear two, the metal gear two meshing with the transverse racks, adjusting columns fixedly connected to the outer sides of both the longitudinal and transverse racks, and a clamping mechanism installed inside the body for clamping and fixing the wire.

[0006] Through the above technical solution: the motor acts as the power source, driving the shaft to rotate after startup. When the shaft rotates, the metal gear one fixed on its outer side rotates synchronously. Since the metal gear one meshes with the longitudinal racks on the front and rear sides, during the rotation of the gear, it drives the longitudinal racks to make longitudinal linear motion. At the same time, the metal gear two at the left end of the shaft also rotates. The metal gear two meshes with the transverse racks at the upper and lower ends, thereby driving the transverse racks to make transverse linear motion. Adjusting columns are fixedly connected to the outer sides of both the longitudinal and transverse racks. The adjusting columns will also change their positions accordingly. Ultimately, the operation of the motor drives the adjusting columns to move in different directions to meet the corresponding adjustment requirements, thus realizing the tension adjustment of wires of different specifications and sizes.

[0007] As a further description of the above technical solution:

[0008] The clamping mechanism includes a loading box, which is installed inside the machine body. A knob is provided on the top of the loading box, a connecting rod is fixedly connected to the bottom of the knob, a rotating rod is fixedly connected to the bottom of the connecting rod, a clamping ring one is provided on the outer side of the rotating rod, a limit block is fixedly connected to the rear side of the clamping ring one, and a clamping ring two is fixedly connected to the upper middle part of the front side of the outer wall of the loading box.

[0009] The above technical solution involves rotating a knob, which in turn rotates a connecting rod. This rotation causes the outer clamping ring 1 to move. Since there is a limit block on the rear side of clamping ring 1, it restricts the trajectory. Clamping ring 2, which is fixedly connected to the upper middle part of the front side of the outer wall of the loading box, cooperates with clamping ring 1 to effectively clamp the wire, protect the connected parts, and adjust the tension.

[0010] As a further description of the above technical solution:

[0011] A warning sign is provided on the left side of the outer wall of the machine body, and a screw is threaded onto the outer side of the warning sign.

[0012] The above technical solution involves installing a warning sign on the machine body and securing it with screws.

[0013] As a further description of the above technical solution:

[0014] Support legs are fixedly connected to the four corners of the bottom of the machine body, and foot pads are fixedly connected to the bottom of the support legs.

[0015] The above technical solution involves installing support legs at the bottom of the machine body to support the entire structure.

[0016] As a further description of the above technical solution:

[0018] The above technical solution involves installing a storage box on the machine body and a cover on the storage box.

[0019] As a further description of the above technical solution:

[0021] The above technical solution involves mounting a block on the machine body, with a hook fixedly connected to the mounting block.

[0022] As a further description of the above technical solution:

[0023] A connecting block is fixedly connected to the top of the machine body, and a fixing rod is fixedly connected to the outside of the connecting block.

[0024] The above technical solution involves installing a connecting block on the machine body and a fixing rod on the connecting block.

[0025] As a further description of the above technical solution:

[0026] A support pole is provided at the top of the machine body, and a light bulb is installed at the top of the support pole.

[0027] The above technical solution involves installing a support pole on the machine body and a light bulb on the support pole.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, after the motor starts, the drive shaft and the first metal gear rotate synchronously. The gear meshes with the longitudinal rack, and the shaft also drives the second metal gear to rotate, meshing with the transverse rack and causing it to move laterally.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a device for conveniently adjusting the tension of a wire, comprising a body 1, a motor 3 mounted on the outer side of the body 1, a rotating shaft 4 fixedly connected to the output end of the motor 3, the kinetic energy of the motor 3 driving the rotating shaft 4 to rotate, a metal gear 5 fixedly connected to the outer side of the rotating shaft 4, thus driving the metal gear 5 to move, longitudinal racks 6 are provided on both the front and rear sides of the metal gear 5, the metal gear 5 meshing with the longitudinal racks 6, a metal gear 7 fixedly connected to the left end of the rotating shaft 4, thus also driving the metal gear 7 to rotate, the outer side of the metal gear 7... Both the upper and lower ends are provided with transverse racks 8, and metal gears 7 are meshed with the transverse racks 8. Adjustment columns 9 are fixedly connected to the outer sides of the longitudinal racks 6 and the transverse racks 8. A clamping mechanism 2 is installed inside the body 1. The clamping mechanism 2 is used to clamp and fix the wire. A warning sign 10 is provided on the left side of the outer wall of the body 1. The outer side of the warning sign 10 is threaded with screws 11. The warning sign 10 is fixed by the screws 11 to serve as a warning. Support legs 12 are fixedly connected to the four corners of the bottom of the body 1. Foot pads 13 are fixedly connected to the bottom of the support legs 12 to support the whole body.

[0040] Specifically, motor 3, as the power source, drives shaft 4 to rotate after startup. The rotation of shaft 4 drives the metal gear 5 fixed on its outer side to rotate synchronously. Metal gear 5 meshes with the longitudinal racks 6 on the front and rear sides. Therefore, during the rotation of the gear, the longitudinal racks 6 can perform longitudinal linear motion. At the same time, the metal gear 7 at the left end of shaft 4 also rotates. This gear meshes with the transverse racks 8 at the upper and lower ends, thereby causing the transverse racks 8 to perform transverse linear motion. Adjusting columns 9 are fixedly connected to the outer sides of both the longitudinal racks 6 and the transverse racks 8. The position of the adjusting columns 9 changes accordingly. Through the operation of motor 3, the adjustment columns 9 are driven to move in different directions to meet the needs of tension adjustment for wires of different specifications and sizes.

[0041] Reference Figure 1 , Figure 3 and Figure 5The clamping mechanism 2 includes a loading box 201, which is installed inside the machine body 1. A knob 202 is located on the top of the loading box 201, and a connecting rod 203 is fixedly connected to the bottom of the knob 202. Rotating the knob 202 causes the connecting rod 203 to rotate. A rotating rod 204 is fixedly connected to the bottom of the connecting rod 203, which in turn causes the rotating rod 204 to rotate. A clamping ring 205 is located on the outer side of the rotating rod 204, and a clamping ring 205 is fixedly connected to the rear side of the clamping ring 205. The limiting block 206 serves to limit the trajectory. A clamping ring 207 is fixedly connected to the upper middle part of the front side of the outer wall of the loading box 201. A storage box 14 is provided on the lower middle part of the right side of the outer wall of the machine body 1. A cover plate 15 is provided on the top wall of the storage box 14. A cover plate 15 is installed on the storage box 14 to place maintenance parts. A placement block 16 is fixedly connected to the middle right side of the outer wall of the machine body 1. A hook 17 is fixedly connected to the outside of the placement block 16, and some tools can be hung on the hook 17.

[0042] Specifically, rotating the knob 202 drives the connecting rod 203 to rotate, which in turn causes the rotating rod 204 to rotate. The rotation of the rotating rod 204 causes the outer clamping ring 205 to move accordingly. Since the clamping ring 205 has a limiting block 206 on its rear side, the limiting block 206 plays a role in limiting the trajectory. At the same time, the clamping ring 207 fixedly connected to the upper middle part of the front side of the outer wall of the loading box 201 cooperates with the clamping ring 205, so as to effectively clamp the wire and adjust the tension. On the lower middle part of the right side of the outer wall of the machine body 1, there is a storage box 14 with a cover plate 15 on its top wall. The cover plate 15 is installed on the storage box 14 for storing maintenance parts. In addition, the middle right side of the outer wall of the machine body 1 has a fixedly connected placement block 16. The outer side of the placement block 16 has a fixedly connected hook 17. The hook 17 can be used to hang tools. The model of the motor 3 is JZBOBO2.

[0043] Reference Figure 1 and Figure 2 A connecting block 18 is fixedly connected to the top of the body 1, and a fixing rod 19 is fixedly connected to the outside of the connecting block 18 to serve as a connection. A vertical pole 20 is provided at the top of the body 1, and a light bulb 21 is installed at the top of the vertical pole 20 to serve as an illumination.

[0044] Specifically, the top of the body 1 is provided with a connecting block 18, and a fixing rod 19 is fixedly provided on the outside of the connecting block 18 to realize the connection function. The top of the body 1 is provided with a pole 20, and a light bulb 21 is installed on the top of the pole 20 to provide lighting function.

[0045] Working principle: Motor 3 serves as the power source for the entire mechanical device. After its startup, it drives the rotating shaft 4 to rotate. During the rotation of the rotating shaft 4, the metal gear 5 fixed on its outer side rotates synchronously. The metal gear 5 is precisely meshed with the longitudinal racks 6 on the front and rear sides. Therefore, when the metal gear 5 rotates, it drives the longitudinal racks 6 to perform corresponding longitudinal linear motion. At the same time, the metal gear 7 on the left end of the rotating shaft 4 also rotates with the rotation of the rotating shaft 4. The metal gear 7 is also precisely meshed with the transverse racks 8 at the upper and lower ends. Therefore, during the rotation of the metal gear 7, it drives the transverse racks 8 to perform transverse linear motion. Adjusting columns 9 are fixedly connected to the outer sides of both the longitudinal racks 6 and the transverse racks 8. Therefore, when the racks perform linear motion, the adjusting columns 9 will also change their positions accordingly. The operation of motor 3 can drive the adjusting columns 9 to move in different directions, thereby meeting the needs of tension adjustment for wires of different specifications and sizes.

[0046] By rotating the knob 202, the rotation of the knob 202 will directly drive the connecting rod 203 to rotate accordingly. The rotation of the connecting rod 203 will cause the rotating rod 204 to rotate as well. The rotation of the rotating rod 204 will cause the outer clamping ring 205 to move along a specific trajectory. During the movement of the clamping ring 205, a limit block 206 is provided on its rear side. The function of this limit block 206 is to restrict the movement trajectory of the clamping ring 205 and ensure that it moves along the predetermined path. The loading box 201 is also equipped with a clamping ring 207. There is a close cooperation between the clamping ring 207 and the clamping ring 205 to effectively clamp the wire.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
