Description

Technical Field

[0001] This utility model relates to the field of wire processing equipment technology, and in particular to a rotary connector for multi-strand parallel metal wires. Background Technology

[0002] Wires and cables are wire products composed of at least one conductor used to transmit electrical (magnetic) energy, information, and realize electromagnetic energy conversion. In the manufacturing or use of cables, there is an unavoidable phenomenon: the metal conductors used in cables are not infinitely long, so the length of the cable is also fixed. In addition, when using actual cables (especially multi-strand metal wires), they need to be connected to other multi-strand metal wires (as referred to as "two wires" in the following text). That is, after the metal conductor in the former multi-strand metal wire is used up, it must be connected to the metal conductor in the latter multi-strand metal wire (usually by welding) to meet the processing and use requirements.

[0003] Conventional wiring processes are basically manual welding operations, which have some problems. When welding multi-strand parallel wires, clamps are needed to clamp and fix the metal parallel wires. However, it is inconvenient to adjust the tension of the parallel wires and the length of the connection position of the two sets of parallel wires during the clamping process, so it is difficult to guarantee the wiring effect of the metal parallel wires.

[0004] Therefore, it is necessary to invent a rotary connector with multi-strand parallel metal wire to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a rotary connector with multi-strand parallel metal wire to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotating connector for multi-strand parallel metal wires, comprising a fixed frame, with movable plates inserted into both ends of the fixed frame, and a support shaft rotatably mounted on one end of each of the two movable plates via bearings, with a guide wheel fixedly mounted on one end of each of the two support shafts, and the two guide wheels being located on the same horizontal line, with two symmetrically distributed grooves formed in the middle of the outer side walls of each of the two guide wheels, with clamping blocks provided inside each of the two grooves, and a strip-shaped positioning groove penetrating through the middle of each of the two clamping blocks, with positioning rods fixedly mounted inside each of the two grooves, and the two positioning rods respectively located inside the two positioning grooves, and pressure blocks fixedly mounted on the outer side walls of each of the two clamping blocks;

[0007] Both movable plates are fixedly provided with racks on their sides that are close to each other. The fixed frame is provided with gears that can be rotated through bearings, and the gears are located between the two racks.

[0008] Preferably, a worm gear is fixedly provided at the bottom end of the gear, and the worm gear is located below the fixed frame. A worm is rotatably provided on the lower surface of the fixed frame, and the worm meshes with the worm gear.

[0009] Preferably, one end of the outer wall of the support shaft is provided with a plurality of protruding teeth, and the plurality of protruding teeth are all of an inclined structure. One end of the outer wall of the movable plate is provided with a movable seat rotatably via a pin, and a torsion spring is provided between the movable seat and the movable plate. The outer wall of the movable seat is fixedly provided with a clamping plate of an inclined structure, and the clamping plate is adapted to the protruding teeth. A lever is fixedly provided on the outer side of the clamping plate.

[0010] Preferably, a rubber block is fixedly provided on the inner side of the clamping block, and a plurality of anti-slip grooves are provided on one side of the rubber block.

[0011] Preferably, both sides of the fixed frame are provided with a strip-shaped sliding groove, and the outer sides of the two movable plates are each provided with two support sliding rods that are adapted to the sliding groove.

[0012] Preferably, a support is fixedly provided at the bottom end of the fixing frame.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model, by setting up a movable plate, a support shaft, and guide wheels, has two sets of each, and the distance between the two sets of movable plates can be adjusted. When connecting multiple strands of parallel metal wires, the multiple strands of parallel metal wires are guided by the two guide wheels respectively. The multiple strands of parallel metal wires overlap between the two sets of guide wheels. The connection of the multiple strands of parallel metal wires is completed by welding the overlapping part of the parallel metal wires. During this process, the tension of the parallel metal wires can be adjusted by rotating the guide wheels, and the overlap range between the multiple strands of parallel metal wires can be adjusted by adjusting the distance between the two movable plates, thereby ensuring the stability of the connected multiple strands of parallel metal wires.

[0015] 2. This utility model, by setting a guide wheel, a groove, and clamping blocks, allows the metal parallel wire to be wound around the outside of the guide wheel when guided by the guide wheel. The metal parallel wire is then pressed between the two clamping blocks, causing the two clamping blocks to flip into the groove. At this time, the two clamping blocks can clamp and fix the metal parallel wire. After the metal parallel wire is connected, pressing the pressure block on the outside of the clamping block causes the clamping block to flip outward, which can quickly release the limitation of the metal parallel wire. This allows the device to quickly clamp and release the metal parallel wire, thereby improving the connection efficiency of the metal parallel wire. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] This utility model provides, for example Figures 1-5 The rotating connector for multi-strand metal wires shown includes a fixed frame 1, with movable plates 2 inserted into both ends of the fixed frame 1. One end of each movable plate 2 is rotatably provided with a support shaft 3 via a bearing. One end of each support shaft 3 is fixed with a guide wheel 4, and the two guide wheels 4 are located on the same horizontal line. It should be noted that the guide wheel 4 adopts the existing structure in the prior art, and its outer side is provided with a groove for guiding the multi-strand metal wires.

[0024] Two symmetrically distributed grooves 5 are opened in the middle of the outer side wall of each of the two guide wheels 4. Each groove 5 is equipped with a clamping block 6. Each clamping block 6 has a strip-shaped positioning groove 7 penetrating through its middle. Each groove 5 is fixed with a positioning rod 8, and the two positioning rods 8 are respectively located inside the two positioning grooves 7. Each clamping block 6 is fixed with a pressure block 9. Each clamping block 6 is fixed with a rubber block 18, and one side of the rubber block 18 is provided with multiple anti-slip grooves. The rubber block 18 can deform to a certain extent when it is squeezed. During the flipping process of the two clamping blocks 6, the rubber block 18 and the metal wire are squeezed against each other. During this process, the rubber block 18 deforms to a certain extent to avoid the metal wire being squeezed and damaged.

[0025] A rack 10 is fixedly provided on the side of the two movable plates 2 that are close to each other. A gear 11 is rotatably provided inside the fixed frame 1 through a bearing, and the gear 11 is located between the two racks 10. The gear 11 and the rack 10 cooperate to ensure that the two movable plates 2 move synchronously in opposite directions.

[0026] A worm gear 12 is fixedly provided at the bottom end of the gear 11, and the worm gear 12 is located below the fixed frame 1. A worm 13 is rotatably provided on the lower surface of the fixed frame 1, and the worm 13 meshes with the worm gear 12. The worm 13 and the worm gear 12 cooperate to realize the transmission of the gear 11 while locking its position, so as to lock the position between the two movable plates 2. It should be noted that a handwheel is provided at one end of the worm 13 to facilitate its rotation.

[0027] The outer side wall of the support shaft 3 is surrounded by multiple protruding teeth 14, and all the protruding teeth 14 are inclined. The outer side wall of the movable plate 2 is rotatably provided with a movable seat 15 through a pin, and a torsion spring is provided between the movable seat 15 and the movable plate 2. The outer side wall of the movable seat 15 is fixed with an inclined clamping plate 16, and the clamping plate 16 is adapted to the protruding teeth 14. A lever 17 is fixed on the outer side of the clamping plate 16. The lever 17 is used to facilitate the user to adjust the position of the clamping plate 16 to separate it from the protruding teeth 14, thereby facilitating the release of the guide wheel 4.

[0028] Both sides of the fixed frame 1 are provided with strip-shaped sliding grooves 19. Two support sliding rods 20 that are adapted to the sliding grooves 19 are fixed on the outer side of the two movable plates 2. The support sliding rods 20 cooperate with the sliding grooves 19 to ensure the stability of the sliding of the movable plates 2.

[0029] A support 21 is fixedly provided at the bottom of the fixed frame 1. The support 21 is used to support the device. Mounting holes can be opened on the support 21 as needed to install and fix the device.

[0030] Working principle of this utility model:

[0031] In use, this device divides multiple strands of metal wire into two groups, and guides each group of wires through one guide wheel 4 and then wraps them around the outside of the other guide wheel 4. The ends of the wires are then inserted between two clamping blocks 6, and the wires are pressed against the blocks 6, causing the blocks 6 to rotate around the positioning rod 8. At this point, the positioning rod 8 slides to one end of the positioning groove 7, and the two clamping blocks 6 are completely rotated into the groove 5. The two clamping blocks 6 then clamp and fix the metal wires using the rubber blocks 18 on their inner sides. The positioning rod 8 then presses against one end of the positioning groove 7. The parallel wires apply a reaction force to the clamping block 6, preventing the clamping block 6 from rotating. The two sets of parallel metal wires are then fixed to the outside of the two guide wheels 4. Then, the worm 13 is rotated, causing the worm 13 to drive the worm wheel 12 to rotate. The worm wheel 12 drives the gear 11 to rotate, and the gear 11 simultaneously drives the two racks 10 to move. The two racks 10 simultaneously drive the two movable plates 2 to move, causing the two movable plates 2 to move in opposite directions. The two movable plates 2 respectively drive the two guide wheels 4 to move, thereby adjusting the distance between the two guide wheels 4 and thus adjusting the overlapping position between the two sets of parallel metal wires.

[0032] After the position of the guide wheel 4 is adjusted, the two support shafts 3 are rotated respectively, so that the two support shafts 3 drive the two guide wheels 4 to rotate respectively. The two guide wheels 4 pull the two sets of metal parallel wires until the two sets of metal parallel wires are in a taut state, so as to facilitate subsequent welding and wiring operations. During the rotation of the support shaft 3, the support shaft 3 drives the convex tooth 14 to rotate. During the rotation of the convex tooth 14, its inclined surface presses against the clamping plate 16, so that the clamping plate 16 drives the movable seat 15 to rotate. When the support shaft 3 rotates to the position, the movable seat 15 is reset under the action of the torsion spring, and drives the clamping plate 16 to rotate so as to clamp the convex tooth 14, so as to achieve the limiting and fixing of the guide wheel 4.

[0033] After the metal wire is wired, the lever 17 is turned to rotate the clamping plate 16 and the movable seat 15, so that the clamping plate 16 is separated from the tooth 14. At this time, the limit on the support shaft 3 is released, the limit on the guide wheel 4 is released, and the tension of the metal wire is released. Then, the pressure block 9 is pressed to move the clamping block 6. The two clamping blocks 6 first move closer to each other, so that the positioning rod 8 slides in the positioning groove 7. At this time, the clamping block 6 can rotate and then pull the metal wire outward, so that the metal wire drives the clamping block 6 to flip outward. At this time, the limit between the metal wire and the guide wheel 4 is released, and the wired metal wire can be removed.

[0034] It should be noted that this embodiment only provides the relevant structure for the connection position of the metal parallel wires. The fixing clamp structure for the unconnected end of the metal parallel wires can adopt the relevant structure in the prior art, and there is no limitation here. This embodiment can not only realize the clamping and fixing of two metal parallel wires during the connection process, but also realize the clamping and fixing of multiple metal parallel wires during the connection process.

[0035] 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.
