Description

Technical Field

[0001] The utility model belongs to the technical field of wire twisters, and particularly relates to a wire twister. Background Art

[0002] When manufacturing electrical appliances and electrical components such as household appliances, lamps, electric toys, motor windings, heating wire groups, and transformer coils, wiring is required between electrical parts. Usually, two or more stripped wire ends or conductors need to be twisted together for wiring.

[0003] During the wiring process, the operation of twisting multiple wire ends together is always completed by manual twisting. There has been no efficient and fast automatic or semi-automatic tool to replace manual wire twisting. This manual wire twisting operation causes great harm to the operator's fingers, has low efficiency, and unstable quality: if the wires are not tightly twisted together, it is easy to cause poor electrical connection.

[0004] Therefore, people have developed wire twisters, which have the advantages of high working efficiency, reduced labor intensity, and stable quality of the twisted wire ends. Patent Publication No. CN217522348U discloses a wire twister, which includes a housing and a driving mechanism, an elastic mechanism, a centrifugal body, a first slider, a second slider, a first clamp, and a second clamp located inside the housing. The first clamp has a plurality of first jaws, and the second clamp has a plurality of second jaws. The plurality of first jaws and the plurality of second jaws are oppositely arranged and cross each other, so as to form a wire twisting space between the plurality of first jaws and the plurality of second jaws. After the first jaw and the second jaw cross each other, the first jaw crosses over the second jaw and is fixed to the first slider, and after the second jaw and the first jaw cross each other, the second jaw crosses over the first jaw and is fixed to the second slider. The centrifugal body is provided with a chute in the radial direction. The first slider and the second slider are both located in the chute and can move radially along the chute. The elastic mechanism is located in the chute and connects the first slider and / or the second slider. The driving mechanism is used to drive the centrifugal body to rotate and drive the first clamp and the second clamp to move relatively. The centrifugal force generated by the slider directly acts on the first clamp and the second clamp, so that the centrifugal force is not lost and a multiple clamping force is generated, which can twist some relatively hard loose wires (such as thin iron wires, copper wires, etc.), overcoming the defect that it is difficult for the existing wire twisters to twist hard loose wires tightly.

[0005] The elastic mechanism of the wire twister includes a first spring and a second spring. The first spring is connected to the first slider and is located between the first slider and the first baffle. The second spring is connected to the second slider and is located between the second slider and the second baffle. Under the action of the elastic force, the first slider and the second slider move closer to each other, while the first clamp and the second clamp move away from each other. A wire twisting space is formed between the first clamping jaw provided on the first clamp and the second clamping jaw provided on the second clamp, and the wire can move in the wire twisting space. After the wire twister is started, the centrifugal body rotates. Under the action of the centrifugal force, the first slider and the second slider move away from each other, while the first clamp and the second clamp move closer to each other, and the first clamping jaw and the second clamping jaw also move closer to each other to clamp the wire located in the wire twisting space.

[0006] For the wire twister of this solution, the first spring is located between the first slider and the first baffle, and the second spring is located between the second slider and the second baffle. In the initial state, the spring reset can separate the two clamps, ensuring that in the initial state, the wire twister has a wire twisting space where wire can be released. When the wire is placed in the wire twisting space, the clamps close and clamp while twisting the wire. It can achieve a good wire twisting effect for soft wires that do not require a large clamping force. However, this solution relies on the action of the centrifugal force during wire twisting to compress the spring and overcome the elastic force, so that the clamps tighten and hold. As a result, the clamping force of this wire twister depends on the centrifugal force, and it also has to overcome the elastic force of the spring when clamping. Therefore, this wire twister will slip when twisting thick and hard wires, and it is difficult to achieve a good wire twisting effect for thick and hard wires. Utility Model Content

[0052] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0053] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element and integrated with it, or there may be an intermediate element at the same time. The terms "installation", "one end", "the other end" and similar expressions used in this article are only for the purpose of illustration.

[0054] Unless otherwise defined, all technical and scientific terms used in this article have the same meaning as commonly understood by those skilled in the technical field to which this technology belongs. The terms used in the description of this article are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The term "and / or" used in this article includes any and all combinations of one or more of the related listed items.

[0055] Please refer to Figures 1 to 8, an embodiment of the present utility model provides a wire twister, which includes a first slider 100, a second slider 200, a first clamp 300, a second clamp 400, a centrifugal body 500, an elastic mechanism 600 and a driving mechanism 700.

[0056] Among them, both the first clamp 300 and the second clamp 400 have clamping arms. The first clamp 300 is connected to the first slider 100, the second clamp 400 is connected to the second slider 200. The centrifugal body 500 is provided with a chute 510 in the radial direction. Both the first slider 100 and the second slider 200 are located in the chute 510 and can move radially along the chute 510.

[0057] The elastic mechanism 600 is located between the first slider 100 and the second slider 200, causing the first slider 100 and the second slider 200 to move away from each other, and the clamping arms of the first clamp 300 and the second clamp 400 to move closer to each other; when the elastic mechanism 600 is externally squeezed, the first slider 100 and the second slider 200 move closer to each other, and the clamping arms of the first clamp 300 and the second clamp 400 move away from each other, forming a wire twisting space 900 between the clamping arms of the first clamp 300 and the second clamp 400.

[0058] The driving mechanism 700 drives the centrifugal body 500 to rotate to twist the wire clamped by the clamping arms.

[0059] It can be understood that for the wire twister provided by the embodiment of the present utility model, by arranging the relatively sliding first slider 100 and second slider 200 in the chute 510 of the centrifugal body 500 and arranging the elastic mechanism 600 between the first slider 100 and the second slider 200, the first slider 100 and the second slider 200 move away from each other under the action of elastic force, and at the same time, the clamping arms of the first clamp 300 and the second clamp 400 can move closer to each other; when the elastic mechanism 600 is externally squeezed, the first slider 100 and the second slider 200 move closer to each other, and the clamping arms of the first clamp 300 and the second clamp 400 move away from each other, forming a wire twisting space 900. The wire to be twisted can be placed in the wire twisting space 900. After removing the external force, under the reset action of the elastic mechanism 600, the clamping arms can clamp the wire; the centrifugal body 500 rotates to twist the wire, so that the wire twisting process no longer needs to rely on centrifugal force to overcome the elastic force of the elastic mechanism 600 to clamp the wire to be twisted. The elastic force generated by the elastic mechanism 600 can directly act on the clamping arms of the first clamp 300 and the second clamp 400, and it is not easy to slip when twisting thick and hard wire materials, and good wire twisting of thick and hard wire materials can be achieved.

[0060] Of course, the first clamp 300 can be provided with a plurality of first clamping jaws 310, and the first clamp 300 is arranged on the first slider 100.

[0061] The second clamp 400 may be provided with a plurality of second jaws 410, and the second clamp 400 is arranged on the second slider 200.

[0062] A plurality of first jaws 310 and a plurality of second jaws 410 are arranged opposite to each other and cross each other to form a wire twisting space 900. For example, three first jaws 310 may be provided, and two second jaws 410 may be provided. Each jaw may be arc-shaped or V-shaped, and each second jaw 410 is inserted at a position between each adjacent first jaw 310. This can further prevent the wire from coming out during the wire twisting process.

[0063] Specifically, in some embodiments of the present invention, the elastic mechanism 600 may be a spring. The first end of the spring abuts against the first slider 100, and the second end of the spring abuts against the second slider 200. Setting the elastic mechanism 600 as a spring can make the structure of the wire twister simpler and also facilitate installation and disassembly.

[0064] In addition, in order to facilitate opening the wire twisting space 900 and easily inserting the wire into the wire twisting space 900, in some embodiments of the present invention, the wire twister further includes a push rod 800. The push rod 800 is connected to the first slider 100 or the second slider 200. When an external force presses the push rod, the elastic mechanism 600 is extruded by the external force, and the first slider 100 and the second slider 200 can be pushed to approach each other. At this time, the first jaws 310 and the second jaws 410 move away from each other, and the wire twisting space 900 becomes larger, and the wire can be more easily inserted into the wire twisting space 900; after releasing the push rod 800, under the elastic force of the spring, the first slider 100 and the second slider 200 move away from each other, the first jaws 310 and the second jaws 410 move closer to each other, and the wire twisting space 900 becomes smaller to clamp the wire located in the wire twisting space 900.

[0065] Furthermore, in some embodiments of the present invention, the push rod 800 includes a first push rod 810 and a second push rod 820.

[0066] The first push rod 810 is connected to the first slider 100, and the second push rod 820 is connected to the second slider 200. This can enable the operator to press the first push rod 810 and the second push rod 820 to make the first slider 100 and the second slider 200 approach each other, so that it is more labor-saving, easier and more convenient to insert the wire into the wire twisting space 900, and it can be operated with one hand.

[0067] In some embodiments of the present invention, the wire twister further includes a housing 910. The driving mechanism 700, the centrifugal body 500, the first slider 100, the second slider 200 and the elastic mechanism 600 are all located inside the housing 910, and a part of the push rod 800 extends outside the housing 910, which can facilitate the operation of the push rod 800.

[0068] CombinedFigure 1 and Figure 2 In order to ensure the stability of the first slider 100 and the second slider 200 during the sliding movement of moving away from or approaching each other, so as to improve the service life of the wire twister, in some embodiments of the present invention, the wire twister further includes a first baffle 830 and a second baffle 840 fixed to the centrifugal body 500.

[0069] The first baffle 830 is located on the first side of the chute 510 and can limit the first slider 100 from sliding out of the chute 510.

[0070] The second baffle 840 is located on the second side of the chute 510 and can limit the second slider 200 from sliding out of the chute 510.

[0071] The first push rod 810 passes through the first baffle 830 and is connected to the first slider 100, and the second push rod 820 passes through the second baffle 840 and is connected to the second slider 200. That is to say, a first through hole can be provided on the first baffle 830, the first push rod 810 passes through the first through hole and is connected to the first slider 100, a second through hole is provided on the second baffle 840, and the second push rod 820 passes through the second through hole and is connected to the second slider 200.

[0072] Combined with Figure 5 and Figure 6 In order to prevent the elastic mechanism 600 from popping out, ensure the normal operation of the elastic mechanism 600 and improve the safety of the wire twister, in some embodiments of the present invention, the first slider 100 is provided with a first mounting hole 120, the second slider 200 is provided with a second mounting hole 220, the first mounting hole 120 and the second mounting hole 220 are arranged oppositely, and one end of the elastic mechanism 600 is located in the first mounting hole 120 and the other end is located in the second mounting hole 220.

[0073] Combined with Figure 5 and Figure 6 In some embodiments of the present invention, both the first clamp 300 and the second clamp 400 have mounting arms connected to the slider. The clamping arm of the first clamp 300 is the first clamping arm 330, the clamping arm of the second clamp 400 is the second clamping arm 430, the mounting arm of the first clamp 300 is the first mounting arm 320, and the mounting arm of the second clamp 400 is the second mounting arm 420. The first mounting arm 320 and the first clamping arm 330 are arranged at an angle. The angle can be 90 degrees, that is, the first mounting arm 320 and the first clamping arm 330 can be arranged perpendicular to each other. The first mounting arm 320 and the second mounting arm are fixed to the first slider 100 after being staggered. The first clamping arm 330 is provided with a plurality of first clamping jaws 310, and the first clamping arm 330 is provided with a first clamping surface 331.

[0074] The second mounting arm 420 and the second clamping arm 430 are arranged at an angle. The angle can be 90 degrees, that is, the second mounting arm 420 and the second clamping arm 430 can be arranged perpendicular to each other. The second mounting arm 420 is fixed to the second slider 200 after intersecting with the first mounting arm. The second clamping arm 430 is provided with a plurality of second jaws 410, and the second clamping arm 430 is provided with a second clamping surface 431.

[0075] The first clamping arm 330 and the second clamping arm 430 are arranged opposite to each other. That is to say, the first clamping surface 331 and the second clamping surface 431 can be arranged parallel to each other. When the first slider 100 and the second slider 200 move away from each other, the first clamping arm 330 and the second clamping arm 430 move closer to each other, and the first clamping surface 331 and the second clamping surface 431 also move closer to each other, so that the first jaw 310 arranged on the first clamping surface 331 and the second jaw 410 arranged on the second clamping surface 431 move closer to each other and clamp the wire. Designing the first clamp 300 to have the first mounting arm 320 and the first clamping arm 330 arranged at an angle, and designing the second clamp 400 to have the second mounting arm 420 and the second clamping arm 430 arranged at an angle can simplify the structures of the first clamp 300 and the second clamp 400, facilitate their installation and maintenance, reduce the manufacturing and use costs, and at the same time greatly increase the strength of the clamp, so that the clamp is not easily deformed and broken during the process of clamping and twisting the wire, and the wire twister has a longer service life.

[0076] Combined Figure 7 , in order to make the product design more compact and make full use of the internal space of the product, in some embodiments of the present invention, a vertical avoidance groove 432 is provided on the second clamping arm 430, and a second avoidance groove 421 is provided on the second mounting arm 420. The vertical avoidance groove 432 and the second avoidance groove 421 communicate with each other. The first mounting arm 320 passes through the vertical avoidance groove 432 and is fixed to the first slider 100. The second avoidance groove 421 can avoid the first slider 100, making full use of the internal space of the product and making the product design more compact and delicate.

[0077] Combined Figure 5 and Figure 6 , in some embodiments of the present invention, the first mounting arm 320 and the second mounting arm 420 are respectively fixed to the first slider 100 and the second slider 200 after intersecting from the sides of each other. Arranging the clamps in a side-by-side cross manner greatly increases the strength of the clamps, so that the clamps are not easily deformed and broken during the process of clamping and twisting the wire, and the wire twister has a longer service life.

[0078] The first clamping arm 330 of the first clamp 300 is offset toward the side close to the second clamp 400 relative to the first mounting arm 320. The second clamping arm 430 of the second clamp 400 is offset toward the side close to the first clamp 300 relative to the second mounting arm 420. It is ensured that when the mounting arms are in a structure where they cross each other laterally, it will not affect the relative arrangement of the first clamping arm 330 and the second clamping arm 430, so that the first jaw 310 and the second jaw 410 can still have a good effect of clamping and twisting wires.

[0079] Combined with Figure 8 , in some embodiments of the present utility model, a first groove 511 and a second groove 512 are provided at the chute 510 of the centrifugal body 500.

[0080] Both the first slider 100 and the second slider 200 are provided with a first protrusion 110 and a second protrusion 210.

[0081] The first protrusion 110 is matched with the first groove 511, and the second protrusion 210 is matched with the second groove 512. When the first slider 100 and the second slider 200 slide, the first groove 511 and the second groove 512 can restrict the movement of the first slider 100 and the second slider 200 in the radial direction, thereby ensuring the stability of the sliding movement of the first slider 100 and the second slider 200, making the wire twisting device clamp the wire located in the wire twisting space 900 more tightly, further preventing the wire from coming out during the wire twisting process, and achieving the purpose and effect of improving the wire twisting efficiency and wire twisting quality.

[0082] Combined with Figure 1 and Figure 2 , in some embodiments of the present utility model, the wire twisting device further includes a housing 910, and the driving mechanism 700, the centrifugal body 500, the first slider 100, the second slider 200 and the elastic mechanism 600 are all located in the housing. The driving mechanism 700 includes a driving member 710 and a driving rod 720.

[0083] The centrifugal body 500 is rotatably arranged at the first end of the housing 910, the driving member 710 is fixed at the second end of the housing 910, and the driving member 710 drives the centrifugal body 500 to rotate through the driving rod 720.

[0084] Rotatably arranging the centrifugal body 500 at the first end of the housing 910 and fixing the driving member 710 at the second end of the housing 910 can make the structure of the housing 910 of the wire twisting device be a long column type, which is convenient for the operator to hold and carry the wire twisting device.
