Description

Technical Field

[0001] This utility model relates to the field of magnetic ring technology, specifically a magnetic ring adjustment structure. 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 (Mn-Zn). Magnetic rings have different impedance characteristics at different frequencies. Generally, the impedance is very small at low frequencies, and the impedance of the magnetic ring increases sharply as the signal frequency increases.

[0003] An adjustable magnetic ring structure is disclosed in CN214336478U, comprising a fixed magnetic ring, which includes a first half-ring and a second half-ring. An extension magnetic ring is disposed at the bottom of the fixed magnetic ring. Several connecting devices are provided between the extension magnetic ring and the fixed magnetic ring. Each connecting device includes a hook and a slot. A first locking strip is disposed inside one end of the slot, and a second locking strip is disposed outside one end of the hook. This invention, through the connecting devices, can connect and fix the fixed magnetic ring and the extension magnetic ring, facilitating changes to the length of the magnetic ring.

[0004] In current magnetic ring adjustment structure designs, when it comes to adjusting the height of the magnetic ring, the commonly used connection methods include interlocking connections and threaded connections. However, the aforementioned technical solution combines these two connection methods. While this combination theoretically seems to combine the advantages of both methods, it actually complicates the connection process. Furthermore, due to the limitations of this combination method, the degree of connection between magnetic rings and the overall integrity are not ideal. Moreover, after the magnetic rings are assembled and adjusted to the required height, the existing design does not provide an effective reinforcement measure to ensure the stability of the assembled magnetic ring structure. This leads to the problem of the assembled magnetic ring structure being prone to redispersing, thus affecting the reliability and service life of the entire magnetic ring adjustment structure.

[0005] Therefore, those skilled in the art have provided a magnetic ring adjustment structure to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a magnetic ring adjustment structure to solve the problems mentioned in the background art, such as the complex connection process of existing magnetic ring adjustment structures and the lack of reinforcement measures after assembly.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A magnetic ring adjustment structure includes: a first magnetic ring, a wedge groove fixedly formed on the bottom surface of the first magnetic ring, a middle magnetic ring installed below the first magnetic ring, tenons integrally formed on both the upper and lower surfaces of the middle magnetic ring, a second magnetic ring installed below the middle magnetic ring, a slot formed on the upper surface of the second magnetic ring, a screw installed on the center line of the first magnetic ring, a collar sleeved on the surface of the screw, clamping rods rotatably connected to both sides of the collar, a torsion spring shaft between the clamping rods and the collar, and a nut threaded onto the surface of the screw.

[0009] As a further embodiment of this utility model: the clamping rod is rotatably connected to the collar via a torsion spring shaft, and the clamping rod is symmetrical about the center line of the collar.

[0010] As a further improvement of this utility model, the screw and the nut cooperate to form a threaded connection.

[0011] As a further embodiment of this utility model: the surface of the middle magnetic ring is engaged with the wedge grooves on the surfaces of the first and second magnetic rings through tenons, and the tenons and the middle magnetic ring are an integrated structure.

[0012] As a further improvement of this utility model, a metal mortise is fixedly provided on the surface of the tenon block.

[0013] As a further embodiment of this utility model: the inner wall of the wedge groove is fixedly provided with an opening, and a tenon is fixedly provided inside the opening. A magnet is fixedly provided on the surface of the tenon, and the surface of the metal mortise is interlocked with the tenon.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. During the adjustment of the magnetic rings, the height of the magnetic rings needs to be adjusted. Specifically, the first and second magnetic rings are placed at the top and bottom positions, respectively, while the middle magnetic ring has a different structure from the first and second magnetic rings. It is located between the two. To ensure the stability of the structure, the top and bottom ends of the middle magnetic ring are designed with protruding tenons. At the same time, the surfaces of the first and second magnetic rings are equipped with wedge-shaped grooves, i.e., wedge slots. By engaging the tenons on the middle magnetic ring with the wedge slots on the magnetic rings, the first, middle, and second magnetic rings can be effectively spliced. This splicing method not only allows the height of the magnetic rings to be adjusted, but also significantly improves the bonding strength between the magnetic rings through the tight fit between the tenons and the wedge slots, thereby enhancing the stability and durability of the entire structure.

[0016] 2. In the assembled magnetic ring structure, a set of screws are inserted, and collars are fitted on these screws. By utilizing the torsion spring shaft set between the clamping rod and the collar, the elastic rotation capability of the clamping rod is significantly improved. This design allows the clamping rod to be flexibly opened and closed according to the height change of the magnetic ring, ensuring the clamping accuracy. Through this mechanism, the upper and lower magnetic rings are tightly clamped together by the clamping rod, thereby stabilizing the entire assembled magnetic ring structure and effectively avoiding performance degradation caused by loosening.

[0023] 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.

[0024] Please see Figures 1-5This utility model provides a magnetic ring adjustment structure, including: a first magnetic ring 1, a wedge groove 7 fixedly opened on the bottom surface of the first magnetic ring 1, a middle magnetic ring 2 installed below the first magnetic ring 1, tenons 8 integrally provided on both the upper and lower surfaces of the middle magnetic ring 2, a second magnetic ring 3 provided below the middle magnetic ring 2, a slot opened on the upper surface of the second magnetic ring 3, the surface of the middle magnetic ring 2 cooperates with the wedge groove 7 on the surface of the first magnetic ring 1 and the second magnetic ring 3 through the tenons 8, and the tenons 8 and the middle magnetic ring 2 are an integral structure, a metal mortise 9 is fixedly provided on the surface of the tenons 8, an opening 14 is fixedly opened on the inner wall of the wedge groove 7, and a tenon 10 is fixedly provided inside the opening 14, a magnet 11 is fixedly provided on the surface of the tenon 10, and the surface of the metal mortise 9 is interlocked with the tenon 10 in the middle;

[0025] Specifically, the first magnetic ring 1 and the second magnetic ring 3 are located at the top and bottom, and the middle magnetic ring 2 is located in the middle. During the splicing and assembly, the tenons 8 on the upper and lower surfaces of the middle magnetic ring 2 and the wedge grooves 7 on the magnetic ring cooperate with each other, so that the first magnetic ring 1 and the second magnetic ring 3 are spliced ​​on the top and bottom of the middle magnetic ring 2. The tenons 8 and the wedge grooves 7 fit together, improving the splicing degree between the magnetic rings. After the tenons 8 are embedded in the wedge grooves 7, the metal mortise 9 on the surface of the tenons 8 will be embedded in the opening 14 inside the wedge grooves 7. The tenon 10 and the upper surface of the metal mortise 9 fit together. The magnet 11 on the surface of the tenon 10 and the metal mortise 9 attract each other. The magnetic attraction structure improves the connection between the middle magnetic ring 2 and the first magnetic ring 1 and the second magnetic ring 3.

[0026] A screw 6 is installed on the center line of the first magnetic ring 1. A collar 4 is fitted on the surface of the screw 6, and clamping rods 5 are rotatably connected to both sides of the collar 4. A torsion spring shaft 12 is provided between the clamping rods 5 and the collar 4. A nut 13 is threaded on the surface of the screw 6. The clamping rods 5 are rotatably connected to the collar 4 through the torsion spring shaft 12. The clamping rods 5 are symmetrical about the center line of the collar 4. The screw 6 and the nut 13 are threaded together to form a threaded connection.

[0027] Specifically, the screw 6 passes vertically through the middle of the first magnetic ring 1, the middle magnetic ring 2, and the second magnetic ring 3, and a collar 4 is fitted on it. The collar 4 and the clamping rod 5 are designed with a rotating structure, so that the clamping rod 5 can cooperate with the torsion spring shaft 12 to work together. The opening and closing angle of the clamping rod 5 can be adjusted according to the assembly height of the magnetic ring to adapt to different assembly requirements. Through the clamping action of the clamping rod 5, the assembled magnetic ring can be reinforced, thereby significantly improving the stability of the magnetic ring. After the clamping rod 5 clamps the magnetic ring, the nut 13 and the screw 6 are connected by threads to form a firm connection, pressing the collar 4. In order to ensure that the collar 4 will not move off the screw 6, after the clamping rod 5 clamps the magnetic ring, the nut 13 is used to press the collar 4 to ensure that it is fixed on the screw 6.

[0028] The working principle of this utility model is as follows:

[0029] When using this invention, firstly, the first magnetic ring 1, the middle magnetic ring 2, and the second magnetic ring 3 are stacked sequentially. The tenon 8 on the surface of the middle magnetic ring 2 engages with the wedge grooves 7 of the first and second magnetic rings 1 and 3, ensuring a tight connection between the magnetic rings. As the tenon 8 is inserted into the wedge groove 7, the metal tenon 9 correspondingly enters the opening 14 and engages with the surface of the tenon 10. At this time, the magnet 11 on the surface of the tenon 10 attracts the metal tenon 9, further enhancing the connection stability between the magnetic rings. Next, the screw 6 is vertically passed through the center of each magnetic ring, and a collar 4 is fitted onto the screw 6. 4. The clamping rods 5 on both sides can rotate flexibly under the action of the torsion spring shaft 12. The opening and closing angle of the clamping rods 5 can be adjusted according to the height of the stacked magnetic rings so that they can tightly clamp the magnetic rings and enhance the overall stability. Finally, by rotating the nut 13, a threaded connection is formed between it and the screw 6. The nut 13 presses down on the collar 4 to ensure that the collar 4 and the clamping rods 5 are firmly fixed on the screw 6, thereby completing the assembly of the entire magnetic ring adjustment structure. In use, this magnetic ring adjustment structure is not only easy to assemble, but also significantly improves the stability and reliability of the magnetic ring through the dual action of the magnetic attraction structure and the clamping structure.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
