Bidirectional combined magnetic ring

Abstract

This utility model relates to the field of magnetic ring bodies, specifically a bidirectional combined magnetic ring, including a connecting ring with placement rings on both sides. Compared to the prior art, this patent uses a tension spring to move a movable rod outward from the connecting ring. A positioning rod and a positioning hole facilitate quick assembly of the placement ring with the connecting ring, resetting the movable rod. Then, a rotating ring drives a slider to rotate counterclockwise within a rotating groove, causing the rounded corner of one end of the movable rod to contact the side of the fixing block. This compresses the movable rod, stretching the tension spring. When one end of the movable rod aligns with the guide hole, the reaction force of the tension spring causes the movable rod to insert into the guide hole, thus completing the combined fixation of the two magnetic ring bodies. Furthermore, pulling the connecting rod outward from the connecting ring allows the movable rod to quickly separate from the guide hole, and pulling the placement ring outward from the connecting ring facilitates easy disassembly of the two magnetic ring bodies for maintenance.

Description

Technical Field

[0001] This utility model relates to the field of magnetic ring bodies, specifically a bidirectional composite magnetic ring. Background Technology

[0002] A magnetic ring is a ring-shaped magnetic conductor. Magnetic rings are commonly used anti-interference components in electronic circuits, and they have a good suppression effect on high-frequency noise. They are generally made of ferrite materials. Magnetic rings have different impedance characteristics at different frequencies. Magnetic rings are usually divided into positive magnetic rings and negative magnetic rings, and two magnetic rings are connected to an external plastic fastener to form a bidirectional combined magnetic ring.

[0003] However, existing bidirectional composite magnetic rings typically use a snap-fit ​​connection between the magnetic ring and the external plastic fastener. When the magnetic ring is pressed into the fastener's claw, the claw elastically opens outward under radial force, allowing the magnetic ring to pass over the claw's protrusion. The claw then springs back and locks the magnetic ring in place. However, the right-angle design at the base of the claw easily leads to stress concentration, causing cracks to develop under repeated assembly or vibration, and making breakage more likely. Due to the lack of a mechanism for convenient installation, fixation, and disassembly of the magnetic ring, although the magnetic ring is easy to install, it is inconvenient for workers to disassemble it during maintenance. Utility Model Content

[0004] The present invention aims to provide a bidirectional combined magnetic ring, which is mainly used to solve the technical problem that the existing technology lacks a mechanism for convenient installation, fixing and disassembly of the magnetic ring, which makes it convenient for workers to disassemble the magnetic ring during maintenance work, even though the magnetic ring is easy to install.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A bidirectional composite magnetic ring includes a connecting ring, with placement rings on both sides of the connecting ring. A placement groove is formed on one side of each placement ring, and the magnetic ring body is placed inside the placement groove. It also includes a positioning component, a snap-fit ​​component, a rotating mechanism, an elastic snap-fit ​​mechanism, and a fixing component. The positioning component is located on one side of the placement ring, and the snap-fit ​​components are located on both sides of the connecting ring. The positioning component and the snap-fit ​​components are interlocked. The rotating mechanism has two parts, both of which are rotatably located on the outside of the connecting ring. Two elastic snap-fit ​​mechanisms are provided, each located on the outside of one of the two rotating mechanisms. The elastic snap-fit ​​mechanisms are movably inserted through one side of the rotating mechanism, with one end of the elastic snap-fit ​​mechanism contacting one side of the placement ring. One end of the elastic snap-fit ​​mechanism has a rounded corner. The fixing component is located on the outside of the connecting ring and is interlocked with the elastic snap-fit ​​mechanism.

[0006] The working principle and beneficial effects of this utility model: 1. Working Principle: The two placement rings are easily combined with the connecting ring through the insertion of the positioning and snap-fit ​​components. A rotating mechanism allows the elastic snap-fit ​​mechanism to rotate, causing the rounded corner at one end of the elastic snap-fit ​​mechanism to contact the side of the fixing component. At this point, the elastic snap-fit ​​mechanism is compressed and stretched outwards from the connecting ring. When the elastic snap-fit ​​mechanism rotates to align with the fixing component, its reaction force causes it to insert into the fixing component, thus conveniently fixing the two placement rings to both sides of the connecting ring. Furthermore, pulling the elastic snap-fit ​​mechanism outwards from the connecting ring again separates it from the fixing component, and pulling the two placement rings to both sides of the connecting ring allows for quick disassembly of the placement rings, facilitating maintenance of the magnetic ring body inside the placement rings.

[0007] 2. Beneficial effects: (1) The moving rod can be moved to the outside of the connecting ring by the tension spring, and the positioning rod and positioning hole facilitate the quick splicing of the placement ring with the connecting ring and the reset of the moving rod. Then, the rotating ring drives the slider to rotate counterclockwise in the rotating groove, so that the rounded corner of one end of the moving rod contacts the side of the fixed block, so that the moving rod is squeezed and the tension spring is stretched. When one end of the moving rod is aligned with the guide hole, the moving rod is inserted into the guide hole due to the reaction force of the tension spring, thus completing the combination and fixation of the two magnetic ring bodies. In addition, by pulling the connecting rod to the outside of the connecting ring, the moving rod is quickly separated from the guide hole. Then, the placement ring is pulled to the outside of the connecting ring, so that the two magnetic ring bodies can be disassembled conveniently for maintenance.

[0008] Preferably, the positioning element includes positioning holes, and a plurality of positioning holes are provided. The plurality of positioning holes are opened on one side of the placement ring and are arranged in a circular array at equal intervals, so that the two placement rings can be respectively fitted onto the snap-fit ​​parts on both sides of the connecting ring through the plurality of positioning holes.

[0009] Preferably, the snap-fit ​​component includes positioning rods, and several positioning rods are provided. One end of each positioning rod is fixedly connected to one side of the connecting ring, and the positioning rods are arranged in a circular array at equal intervals. The positioning holes on one side of the two placement rings are aligned with the positioning rods on both sides of the connecting ring, so that the two placement rings drive the positioning holes to fit on the outside of the positioning rods, which facilitates the quick splicing of the two placement rings with the connecting ring.

[0010] Preferably, the rotating mechanism includes a slider, a connecting plate, a moving hole, and a limiting hole. Two rotating grooves are formed on one side of the connecting ring, extending through both sides of the connecting ring. Two sliders are provided, each slidably connected to one of the two rotating grooves. The two sliders are arranged symmetrically in a circular array. Connecting plates are fixedly connected to both sides of each slider. A moving hole is formed through the outer side of each connecting plate, and a limiting hole communicating with the moving hole is formed on the outer side of the connecting plate. The outer sides of the two sliders are fixedly connected to the same rotating ring near the outer side of the connecting ring, and the inner wall of the rotating ring is rotatably connected to the outer wall of the connecting ring. The slider's rotation within the rotating grooves facilitates the movement of the slider in changing the position of the elastic locking mechanism, thus facilitating the subsequent insertion of the elastic locking mechanism into the fixing component.

[0011] Preferably, the elastic snap-fit ​​mechanism includes a moving rod, a limiting block, a support plate, and a tension spring. Two moving rods are provided, each sliding through one of the two moving holes. A limiting block is fixedly connected to the outer side of one end of each moving rod, and one end of the moving rod has a rounded corner. One side of the limiting block contacts one side of the placement ring. A support plate is fixedly connected to the other end of the moving rod. A tension spring is sleeved on the outer wall of the moving rod. One end of the tension spring is fixedly connected to the inner side of the support plate, and the other end is fixedly connected to the outer side of the connecting plate. The same connecting rod is fixedly connected to the outer side of adjacent support plates. The two magnetic ring bodies are placed inside the two placement slots, and then the connecting rod is pulled outwards towards the connecting ring, causing the connecting rod to move the support plate. This, in turn, causes the support plate to move the moving rod, simultaneously stretching the tension spring. Consequently, one end of the moving rod and the limiting block move into the moving hole and the limiting hole, respectively, facilitating the subsequent splicing of the placement ring and the connecting ring.

[0012] Preferably, the fixing component includes a fixing block and a guide hole. Two sets of fixing blocks are provided, with one end of each set of fixing blocks fixedly connected to both sides of the connecting ring. Each set of fixing blocks has two blocks, and the two fixing blocks are arranged symmetrically in a circular array. The same guide hole is opened on both sides of the fixing block. The rounded corner of one end of the moving rod contacts one side of the fixing block and continuously rotates the rotating ring, causing the moving rod to be compressed and driving the tension spring to stretch. When one end of the moving rod is aligned with the guide hole, due to the reaction force of the tension spring, the moving rod is driven to insert into the guide hole, thereby fixing the two placement rings to both sides of the connecting ring, thus completing the combined fixing of the two magnetic ring bodies.

[0013] Preferably, the inner wall of the guide hole is adapted to one end of the elastic locking mechanism; the inner wall of the guide hole is adapted to one end of the moving rod. Attached Figure Description

Detailed Implementation

[0016] 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.

[0017] like Figures 1-5 As shown, the device includes a connecting ring 1, with placement rings 2 on both sides of the connecting ring 1. A placement groove 3 is provided on one side of the placement ring 2, and a magnetic ring body 4 is placed inside the placement groove 3. It also includes a positioning component, a snap-fit ​​component, a rotating mechanism, an elastic snap-fit ​​mechanism, and a fixing component. The positioning component is located on one side of the placement ring 2, and the snap-fit ​​component is located on both sides of the connecting ring 1. The positioning component and the snap-fit ​​component are connected by insertion. The positioning component includes a positioning hole 5, and there are several positioning holes 5. The several positioning holes 5 are located on one side of the placement ring 2 and are arranged in a circular array at equal intervals. The snap-fit ​​component includes a positioning rod 6, and there are several positioning rods 6. One end of the several positioning rods 6 is fixedly connected to one side of the connecting ring 1 and is arranged in a circular array at equal intervals. The two magnetic ring bodies 4 are placed inside the two placement grooves 3 respectively. Then, the positioning holes 5 on one side of the two placement rings 2 are aligned with the positioning rods 6 on both sides of the connecting ring 1, so that the two placement rings 2 drive the positioning holes 5 to fit on the outside of the positioning rods 6, which makes it convenient for the two placement rings 2 to be quickly spliced ​​with the connecting ring 1. The rotating mechanism consists of two parts, both of which are rotatable and located on the outside of the connecting ring 1. Two elastic locking mechanisms are provided, each located on the outside of one of the rotating parts. Each elastic locking mechanism movably passes through one side of the rotating mechanism, with one end contacting the side of the placement ring 2. One end of each elastic locking mechanism has a rounded corner. A fixing member is located on the outside of the connecting ring 1, and the fixing member is inserted into the elastic locking mechanism. The rotating mechanism includes a slider 8, a connecting plate 9, a moving hole 10, and a limiting hole 11. Two rotating grooves 7 are formed on one side of the connecting ring 1, extending through both sides of the connecting ring 1. Two sliders 8 are provided, each slidingly connected within one of the two rotating grooves 7. The unit comprises two sliders 8 arranged symmetrically in a circular array. Connecting plates 9 are fixedly connected to both sides of each slider 8. A moving hole 10 is formed through the outer side of each connecting plate 9, and a limiting hole 11 communicating with the moving hole 10 is also formed on the outer side of each connecting plate 9. A common rotating ring 17 is fixedly connected to the outer side of each slider 8 near the outer side of the connecting ring 1. The inner wall of the rotating ring 17 is rotatably connected to the outer wall of the connecting ring 1. The elastic locking mechanism includes a moving rod 12, a limiting block 13, a support plate 14, and a tension spring 15. Two moving rods 12 are provided, each sliding through one of the two moving holes 10. A limiting block 13 is fixedly connected to the outer side of one end of each moving rod 12, and one end of the moving rod 12 is rounded. One side of the limiting block 13 contacts one side of the placement ring 2. The other end of the moving rod 12 is fixedly connected to a support plate 14. A tension spring 15 is sleeved on the outer wall of the moving rod 12. One end of the tension spring 15 is fixedly connected to the inner side of the support plate 14, and the other end is fixedly connected to the outer side of the connecting plate 9. The outer sides of adjacent support plates 14 are fixedly connected to the same connecting rod 16. The fixing component includes a fixing block 18 and a guide hole 19. There are two sets of fixing blocks 18. One end of each set of fixing blocks 18 is fixedly connected to both sides of the connecting ring 1. There are two fixing blocks 18 in each set. The two fixing blocks 18 are arranged symmetrically in a ring array. The same guide hole 19 is opened on both sides of the fixing block 18. The inner wall of the guide hole 19 is adapted to one end of the elastic snap-fit ​​mechanism. Rotating the rotating ring 17 counterclockwise causes the rotating ring 17 to drive the slider 8. The rotating groove 7 rotates inside, causing the rounded corner of one end of the moving rod 12 to contact one side of the fixed block 18. The rotating ring 17 continues to rotate, causing the moving rod 12 to be compressed and the tension spring 15 to be stretched. When one end of the moving rod 12 is aligned with the guide hole 19, the reaction force of the tension spring 15 causes the moving rod 12 to be inserted into the guide hole 19, thereby completing the combination and fixation of the two magnetic ring bodies 4. In addition, by pulling the connecting rod 16 outward of the connecting ring 1, the moving rod 12 is quickly separated from the guide hole 19. Then, the placement ring 2 is pulled outward of the connecting ring 1, causing the placement ring 2 to drive the positioning hole 5 to separate from the positioning rod 6 on one side of the connecting ring 1. This allows for convenient disassembly of the two magnetic ring bodies 4 and facilitates maintenance.

[0018] As described above, the specific implementation of this utility model is as follows: Two magnetic ring bodies 4 are placed inside the two placement slots 3 respectively. Then, the connecting rod 16 is pulled outwards towards the connecting ring 1, causing the connecting rod 16 to move the support plate 14. This, in turn, causes the support plate 14 to move the moving rod 12, simultaneously stretching the tension spring 15. One end of the moving rod 12 and the limiting block 13 then move into the moving hole 10 and the limiting hole 11 respectively. Next, the positioning holes 5 on one side of the two placement rings 2 are aligned with the positioning rods 6 on both sides of the connecting ring 1, so that the two placement rings 2, with their positioning holes 5, are fitted onto the outside of the positioning rods 6, facilitating quick splicing of the two placement rings 2 with the connecting ring 1. Then, the connecting rod 16 is released, causing the moving rod 12 to reset. This causes the moving rod 12 to bring one side of the limiting block 13 into contact with one side of the placement ring 2, thereby limiting the position of the placement ring 2. Then, the movement is reversed... The rotating ring 17 is rotated, causing the slider 8 to rotate inside the rotating groove 7. This causes the rounded corner of one end of the moving rod 12 to contact one side of the fixed block 18. As the rotating ring 17 continues to rotate, the moving rod 12 is compressed, which in turn stretches the tension spring 15. When one end of the moving rod 12 is aligned with the guide hole 19, the reaction force of the tension spring 15 causes the moving rod 12 to insert into the guide hole 19. This fixes the two placement rings 2 on both sides of the connecting ring 1, thus completing the combination and fixation of the two magnetic ring bodies 4. In addition, by pulling the connecting rod 16 outward from the connecting ring 1, the moving rod 12 is quickly separated from the guide hole 19. Then, by pulling the placement ring 2 outward from the connecting ring 1, the placement ring 2 causes the positioning hole 5 to separate from the positioning rod 6 on one side of the connecting ring 1. This allows for convenient disassembly of the two magnetic ring bodies 4 and facilitates maintenance.
