Description

Technical Field

[0001] This utility model belongs to the field of transformer frame technology, specifically, it relates to a multifunctional transformer frame. Background Technology

[0002] An electronic transformer is an electrical energy conversion device. Depending on the type, electronic transformers can be divided into single-slot transformers, double-slot transformers, and multi-slot transformers. The main materials of a transformer include a frame, wire, insulating tape, and retaining tape. During manufacturing, the wire needs to be wound into coils on the frame.

[0003] However, different specifications of bobbins are required for transformers of different power ratings, resulting in poor versatility and increased production costs and inventory management difficulties. During operation, the inability to flexibly adjust the position of the winding roller makes transformer installation and debugging cumbersome, reducing work efficiency. Furthermore, the winding roller is highly susceptible to external impacts during installation or use, leading to significant stress on the connection between the winding roller and the mounting base, making it prone to damage.

[0004] To address the aforementioned issues, this application proposes a multifunctional transformer frame. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a multifunctional transformer frame to overcome the above-mentioned technical problems existing in the existing related technologies.

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

[0007] A multifunctional transformer frame includes a base, an adjustment structure on the top of the base, and a limit structure on the top of the base.

[0008] The adjustment structure includes an adjustment column fixedly connected to the top of the base. The outer wall of the adjustment column has a sliding groove. The base is slidably connected to a slider through the sliding groove. A locking post is fixedly connected to one outer wall of the slider. The outer wall of the locking post fits into the inner wall of the sliding groove. A return spring is fixedly connected to the outer wall of the slider near the locking post. A limit post is fixedly connected to the end of the return spring away from the locking post. The limit post is sleeved on the outside of the locking post. A compression spring is fixedly connected to the outer wall of the slider away from the locking post. A winding roller is fixedly connected to the side of the compression spring away from the slider.

[0009] Preferably, the limiting structure includes an installation groove on the outer wall of the adjusting column, and a limiting plate is inserted into the adjusting column through the installation groove. By setting the installation groove and the limiting plate, the sliding groove can be closed to prevent the slider from separating from the adjusting column during use.

[0010] Preferably, a telescopic sleeve is fixedly connected to the outer wall of the slider, and the end of the telescopic sleeve away from the slider is fixedly connected to the inner wall of the winding roller. By setting the telescopic sleeve, it is convenient to support and guide the compression spring, and avoid the compression spring from bending due to the weight of the winding roller during use.

[0011] Preferably, the outer wall of the adjusting column is provided with an expansion groove, which facilitates the separation of the adjusting column.

[0012] Preferably, a threaded column is fixedly connected to the top of the base, and an extrusion block is threadedly connected to the outer wall of the threaded column. By setting the threaded column and the extrusion block, it is convenient to expand the adjusting column.

[0013] Preferably, the bottom of the extrusion block is provided with an inclined angle, and the outer diameter of the bottom of the extrusion block matches the inner diameter of the adjusting column. By providing an inclined angle at the bottom of the extrusion block, a certain guiding effect is provided, making it easier and more accurate to insert the extrusion block component into the adjusting column.

[0014] In summary, the technical effects and advantages of this utility model are as follows: This multifunctional transformer frame, through the coordinated use of adjusting columns, slides, sliders, locking columns, limiting columns, return springs, compression springs, and winding rollers, facilitates the adjustment of the position of the winding rollers by the weight of the coils wound on them, achieving more precise inductance values ​​and coupling coefficients. It also meets the needs of transformers with different power ratings, improving operational convenience. Furthermore, when subjected to external impact, the compression springs can absorb and dissipate some energy through their elastic deformation, reducing the impact on other parts, protecting them from damage, and extending the overall service life of the equipment.

[0015] The use of mounting grooves, limiting plates, threaded columns, and expansion grooves facilitates the adjustment of the diameter of the adjusting column, thereby enabling fine-tuning of the distance between the adjusting column and the winding roller, and ultimately improving the stability between the slider and the winding roller.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-3 A multifunctional transformer frame includes a base 1, an adjustment structure 2 on the top of the base 1, and a limit structure 3 on the top of the base 1.

[0026] The adjustment structure 2 includes an adjustment column 201 fixedly connected to the top of the base 1. The outer diameter of the adjustment column 201 varies, increasing progressively from top to bottom. Four grooves 202 are provided on the outer wall of the adjustment column 201, arranged in a circular array. Four sliders 203 are slidably connected to the base 1 via the grooves 202, each corresponding to one of the four grooves 202. Two locking posts 204 are fixedly connected to one side of each of the four sliders 203. The outer walls of the eight locking posts 204 are respectively connected to the inner sides of the four grooves 202. The slide block 203 is fitted with a return spring 206 fixedly connected to the outer wall of the side of the slider 203 near the locking post 204. The number of return springs 206 is the same as the number of locking posts 204, and the eight return springs 206 are located inside the eight locking posts 204 respectively. The ends of the eight return springs 206 away from the eight locking posts 204 are fixedly connected to limit posts 205, and the ends of the eight limit posts 205 are in contact with the inner side wall of the adjusting post 201. The eight limit posts 205 are respectively set on the outside of the eight locking posts 204. The side of the slider 203 away from the locking post 204 is fixedly connected to a compression spring 207, and the side of the compression spring 207 away from the slider 203 is fixedly connected to a winding roller 208.

[0027] In use, the operator places the winding roller 208 with the coil assembly wound around it outside the adjusting column 201. The weight of the coil assembly on the winding roller 208 causes it to move towards the bottom of the adjusting column 201. Since the outer diameter of the adjusting column 201 increases progressively from top to bottom, as the winding roller 208 moves towards the bottom of the adjusting column 201 with the weight, the distance between the slider 203 and the winding roller 208 gradually decreases as the winding roller 208 moves downwards. At this time, the outer diameter of the groove 202... As the distance between the slider 203 and the winding roller 208 gradually decreases as the slider increases, the compression spring 207 is compressed. As the compression force of the compression spring 207 on the slider 203 gradually increases, the friction between the outer wall of the slider 203 and the outer wall of the adjusting column 201 increases synchronously. When the friction between the slider 203 and the adjusting column 201 is greater than the weight of the winding roller 208 itself, the winding roller 208 stops moving downward. Thus, the equipment can meet the needs of transformers with different power ratings based on the weight of the winding roller 208 and the winding assembly.

[0028] Reference Figure 2 and Figure 4 The limiting structure 3 includes an installation groove 301 on the outer wall of the adjusting column 201. The number of installation grooves 301 is the same as the number of locking columns 204. The adjusting column 201 is inserted with a limiting plate 302 through the installation groove 301. The number of limiting plates 302 is the same as the number of sliding grooves 202. After installation, the operator can insert the limiting plate 302 into the sliding groove 202 to prevent the winding roller 208 from separating from the adjusting column 201 during use.

[0029] Reference Figure 2 and Figure 3 The outer wall of the slider 203 is fixedly connected with a telescopic sleeve 209. The number of telescopic sleeves 209 is the same as the number of compression springs 207, and their positions correspond one-to-one. The telescopic sleeve 209 is a telescopic circular sleeve. During installation, it is sleeved on the outside of the compression spring 207. When the distance between the slider 203 and the winding roller 208 gradually decreases, the length between the two ends of the telescopic sleeve 209 will also gradually decrease. The end of the telescopic sleeve 209 away from the slider 203 is fixedly connected to the inner wall of the winding roller 208.

[0030] Reference Figure 1 The outer wall of the adjusting column 201 is provided with an expansion groove 210. There are four expansion grooves 210. The four expansion grooves 210 are also distributed in a circular array on the outer wall of the adjusting column 201, and the four expansion grooves 210 divide the adjusting column 201 into four modules.

[0031] Reference Figure 1 and Figure 2A threaded post 303 is fixedly connected to the top of the base 1. The bottom center of the threaded post 303 and the center of the adjusting post 201 are located on the same vertical axis. A pressing block 304 is threadedly connected to the outer wall of the threaded post 303. The pressing block 304 is located above the adjusting post 201. When the pressing block 304 is rotated, the pressing block 304 can enter the interior of the adjusting post 201 along the threaded post 303 and expand the adjusting post 201. The bottom of the pressing block 304 is provided with an inclined angle, and the outer diameter of the bottom of the pressing block 304 matches the inner diameter of the adjusting post 201.

[0032] Working principle: In use, the operator places the winding roller 208 with the coil group wound on it outside the adjusting column 201. At this time, the weight of the coil group on the winding roller 208 will drive the winding roller 208 to move towards the bottom of the adjusting column 201. Since the outer diameter of the adjusting column 201 increases step by step from top to bottom, as the winding roller 208 moves towards the bottom of the adjusting column 201 with the weight, the distance between the slider 203 and the winding roller 208 gradually decreases as the winding roller 208 moves downward. At this time, as the slide groove 202... As the outer diameter gradually increases, the distance between the slider 203 and the winding roller 208 gradually decreases, thus compressing the compression spring 207. As the compression force of the compression spring 207 on the slider 203 gradually increases, the friction between the outer wall of the slider 203 and the outer wall of the adjusting column 201 increases synchronously. When the friction between the slider 203 and the adjusting column 201 is greater than the weight of the winding roller 208 itself, the winding roller 208 stops moving downward. Thus, the equipment can meet the needs of transformers with different power ratings based on the weight of the winding roller 208 and the wire assembly.

[0033] In addition, during use or installation, if the winding roller 208 is affected by external impact, the compression spring 207 can absorb and dissipate some of the energy through its own elastic deformation. At the same time, the telescopic sleeve 209 retracts when the winding roller 208 is displaced by external impact, providing a certain displacement space for the compression spring 207, greatly reducing the impact of impact on other parts, protecting the parts from damage, and extending the overall service life of the equipment.

[0034] When the extrusion block 304 is rotated, the extrusion block 304 can enter the interior of the adjusting column 201 along the threaded column 303 and expand the adjusting column 201. After installation, the operator can insert the limiting plate 302 into the slide groove 202 to prevent the winding roller 208 from separating from the adjusting column 201 during use.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
