Description

Technical Field

[0001] This utility model relates to the field of magnetic ring inductor production equipment, and in particular to a novel pulley hook for use in the winding of magnetic ring inductors. Background Technology

[0002] A magnetic ring inductor consists of a toroidal magnetic core and enameled wire wound around its outer surface. The surface of the enameled wire is covered with an insulating layer. In the traditional manufacturing process, manual winding is usually used. However, with the rapid development of electronic technology, especially the rapid progress in the fields of new energy and intelligent technology, the performance requirements for magnetic ring inductors are also constantly increasing. Therefore, the traditional manual production method is gradually being replaced by automated production. In automated production, especially when producing high-power products with multi-strand wire, flat wire, multi-layer insulated wire, and multi-ring stacked wire, the use of a hook device to assist in winding can significantly improve the efficiency of the winding process.

[0003] Currently, most crochet hooks are made of ordinary plastic, which is relatively weak. During the production process, the high-speed contact and friction with the enameled wire generates high temperatures and a high coefficient of friction, resulting in significant wear and tear on the plastic body and a short service life. In addition, these crochet hooks often need to be replaced as a whole after they are discarded. Due to their limited recycling value, a large amount of waste plastic is often generated, which may not only waste resources but also be detrimental to environmental protection.

[0004] Therefore, those skilled in the art have provided a novel pulley hook for use in the winding of magnetic ring inductors to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel pulley hook for winding magnetic ring inductors. This novel pulley hook can extend service life, reduce friction between the hook and the enameled wire, and allow for pulley replacement according to actual needs.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A novel pulley hook for use in the winding of magnetic ring inductors includes a magnetic ring mechanism, a hook body and a pulley body. The hook body has a main body mechanism near its upper end and a connecting mechanism at its lower end.

[0008] The magnetic ring mechanism includes an annular magnetic block and enameled wire. The main body mechanism includes a connecting optical axis and a circular fixing block. The end of the connecting optical axis away from the circular fixing block is provided with a hexagonal slot. The end of the connecting optical axis near the circular fixing block is fixedly provided with a threaded head. The end of the circular fixing block near the connecting optical axis is provided with a threaded groove. The connecting mechanism includes a hexagonal connecting part. The lower end of the hexagonal connecting part is provided with a connecting groove.

[0009] Furthermore, the enameled wire is wound around the outer surface of the annular magnet, and one end of the enameled wire passes around the groove of the pulley body.

[0010] Furthermore, the connecting optical axis is rotatably sleeved on the hook body near the upper end, and the circular fixing block is fixedly sleeved on the side of the hook body near the upper end away from the connecting optical axis.

[0011] Furthermore, the threaded head is threaded in the threaded groove, and the pulley body is rotatably sleeved on the outer surface of the connecting optical shaft.

[0012] Furthermore, the upper end of the hexagonal connector is fixedly connected to the lower end of the hook body, and the interior of the connecting groove is provided with connecting threads.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model proposes a novel pulley hook for use in the winding of magnetic ring inductors. The novel pulley hook has a main body mechanism, in which a connecting optical shaft and a circular fixing block are provided. The connecting optical shaft is made of high-strength material and is detachable from the connecting optical shaft and the circular fixing block through a threaded head. This allows for easy replacement of the pulley body. On the one hand, different shapes and materials of pulley bodies can be replaced according to different application conditions, which greatly improves the applicability of the hook. On the other hand, after the end of its service life, a new pulley body can be replaced simply by disassembly, avoiding the need to replace the entire hook, thereby increasing the cost-effectiveness of customers.

[0015] 2. This utility model proposes a novel pulley hook for winding magnetic ring inductors. This novel pulley hook includes a pulley body that slides along the optical axis when subjected to tension. This reduces the friction and wear between the enameled wire and the pulley body, thus protecting the outer insulating varnish of the enameled wire and effectively ensuring its insulation performance. Furthermore, it saves manpower in manual operation and reduces equipment tension in automated machinery, enabling faster production, saving time and electricity, and increasing cost-effectiveness for customers.

[0016] 3. This utility model proposes a novel pulley hook for winding magnetic ring inductors. The novel pulley hook has a hook body made of high-strength metal. The surface is polished, chamfered, and chrome-plated, which can ensure that the insulation layer will not be damaged when in contact with enameled wire. In addition, using metal instead of plastic can extend the life of the hook and avoid the waste of a large amount of plastic resources, which is beneficial to environmental protection.

[0024] 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.

[0025] Reference Figure 1 , Figure 2 The present invention provides an embodiment of a novel pulley hook for winding magnetic ring inductors, comprising a magnetic ring mechanism 1, a hook body 2 and a pulley body 4, wherein a main body mechanism 3 is provided near the upper end of the hook body 2 and a connecting mechanism 5 is provided at the lower end of the hook body 2.

[0026] Specifically, the magnetic ring mechanism 1 is the magnetic ring structure to be wound. The hook body 2 is made of high-strength metal, with a polished and chamfered surface and chrome plating, which can effectively reduce damage to the insulation layer of the enameled wire 102. The pulley body 4 can be replaced with various materials. For larger products and thicker wire diameters, a steel bearing with an outer plastic wheel body can be used. For smaller products and thinner wire diameters, pure polyetheretherketone (PEEK) material is used. This material has excellent abrasion resistance and high temperature resistance, which can improve the service life. The pulley body 4 includes three models: V-shaped, U-shaped, and H-shaped. The V-shaped pulley is suitable for single strands, the U-shaped is suitable for multi-strands, and the H-shaped is suitable for flat lines. The main body mechanism 3 is the core structure of the hook, which can fix the position of the pulley body 4 and ensure that the pulley body 4 can rotate freely around the axis. The connecting mechanism 5 is used to connect the hook to other structures.

[0027] Reference Figure 1 The magnetic ring mechanism 1 includes an annular magnetic block 101 and an enameled wire 102. The enameled wire 102 is wound around the outer surface of the annular magnetic block 101, and one end of the enameled wire 102 passes around the groove of the pulley body 4.

[0028] Specifically, the annular magnetic block 101 is the magnetic core of the magnetic ring inductor, and the enameled wire 102 is wound on the outer surface of the annular magnetic block 101 in a certain arrangement. During the winding process, the hook body 2 is placed in the middle of the annular magnetic block 101, and one end of the enameled wire 102 passes around the pulley body 4 to facilitate the winding operation of the hook.

[0029] Reference Figure 2-4 The main body 3 includes a connecting optical axis 301 and a circular fixing block 304. The end of the connecting optical axis 301 away from the circular fixing block 304 is provided with a hexagonal slot 303. The end of the connecting optical axis 301 near the circular fixing block 304 is fixedly provided with a threaded head 302. The end of the circular fixing block 304 near the connecting optical axis 301 is provided with a threaded groove 305.

[0030] The connecting optical shaft 301 is rotatably sleeved on the hook body 2 near the upper end, the circular fixing block 304 is fixedly sleeved on the side of the hook body 2 near the upper end away from the connecting optical shaft 301, the threaded head 302 is threadedly sleeved in the threaded groove 305, and the pulley body 4 is rotatably sleeved on the outer surface of the connecting optical shaft 301.

[0031] Specifically, the connecting optical shaft 301 is a structure that fixes the pulley body 4, fixing the pulley body 4 onto the hook. The threaded head 302 and the threaded groove 305 are used to connect the optical shaft 301 and the circular fixing block 304. The detachability of both allows for easy replacement of the pulley body 4. The hexagonal slot 303 facilitates the installation and removal of the connecting optical shaft 301 using tools. The circular fixing block 304 can fix the connecting optical shaft 301. The connecting optical shaft 301 is fixed by thread, which is convenient for disassembly, but can be riveted, laser welded, etc., according to customer requirements to meet various sizes and different application environments.

[0032] Reference Figure 5 The connecting mechanism 5 includes a hexagonal connecting part 501. The lower end of the hexagonal connecting part 501 is provided with a connecting groove 502. The upper end of the hexagonal connecting part 501 is fixedly connected to the lower end of the hook body 2. The connecting groove 502 is provided with a connecting thread inside.

[0033] Specifically, the outer surface of the hexagonal connector 501 is hexagonal, which makes it easy to use a wrench to rotate the hexagonal connector 501 and connect it to other structures. The center point of the hook groove and the center of the connecting rod of the hexagonal connector 501 are on a straight line, which allows for more accurate and stable hooking of the enameled wire 102 during automated winding. The threads inside the connecting groove 502 can enable the hook to be quickly connected to other structures.

[0034] Working principle: When a suitable pulley body 4 needs to be installed, insert a hex screwdriver into the hexagonal slot 303 and rotate the screwdriver. Under the constraint of the hexagonal slot 303, the connecting optical shaft 301 can be kept rotating synchronously, and the threaded head 302 also rotates accordingly. Under the action of the thread on its outer surface, it can be disengaged from the threaded groove 305. Pull the connecting optical shaft 301 outward slightly, and then place the pulley body 4 in the U-shaped groove of the hook body 2, so that the connecting optical shaft 301 and the central axis of the pulley body 4 are on the same horizontal line. Push the connecting optical shaft 301 so that it passes through the pulley body 4, realign the threaded head 302 with the threaded groove 305, and then rotate the screwdriver in the opposite direction so that the threaded head 302 is re-threaded into the threaded groove 305, thus completing the fixing of the connecting optical shaft 301 and the pulley body 4.

[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.
