Description

Technical Field

[0001] This application relates to the field of transformer technology, and in particular to a transformer potting auxiliary fixing structure. Background Technology

[0002] The transformer potting auxiliary fixing structure is a device that achieves stable fixing and size adaptation of the transformer through mechanical linkage. It is mainly used in the potting process to ensure the precise positioning of the transformer. Its advantages include ensuring potting quality, improving versatility and work efficiency, protecting equipment, and having a reliable structure. It is a key auxiliary tool for balancing accuracy, efficiency, and cost.

[0003] Transformer potting auxiliary fixing structure generally consists of basic support components, elastic clamping components, lead wire fixing components, etc. The transformer potting auxiliary fixing structure achieves precise positioning through basic support components, provides dynamic pressure compensation through clamping and limiting components, ensures stable electrical connection through lead wire fixing components, and works in conjunction with mold components to adapt to the potting process. It stabilizes the relative positions of core components such as transformer core, windings, and leads throughout the entire process of glue injection, flow, and curing, and offsets the stress caused by glue impact and curing shrinkage, ultimately ensuring the electrical performance and mechanical reliability of the product after potting.

[0004] Existing transformer potting auxiliary fixing structures cannot be adjusted for transformers of different sizes, resulting in poor versatility. They require separate fabrication of corresponding structures for different transformer specifications, increasing manufacturing costs and storage space, extending production preparation time, and exhibiting low fitting accuracy, which can easily lead to component misalignment, affecting the product's electrical performance and mechanical strength. Furthermore, they lack operational flexibility, requiring disassembly of the entire structure when changing specifications, increasing manual labor and the risk of operational errors. This makes it difficult to meet the flexible production needs of multi-variety, small-batch production, limiting production compatibility and switching efficiency. Therefore, a transformer potting auxiliary fixing structure is proposed to solve these problems. Utility Model Content

[0005] The purpose of this application is to provide a transformer potting auxiliary fixing structure, which aims to improve the problem of not being able to adjust transformers of different sizes.

[0006] The transformer potting auxiliary fixing structure provided in this application adopts the following technical solution: it includes a transformer, an auxiliary fixing mechanism is slidably connected to the bottom of the transformer, a connecting mechanism is slidably connected inside the auxiliary fixing mechanism, and an extension mechanism is slidably connected to the bottom of the auxiliary fixing mechanism. The extension mechanism includes a connecting block, the top of which is slidably connected to the bottom of the auxiliary fixing mechanism. A second sliding plate is fixedly connected to the top of the connecting block, and two limiting rods are fixedly connected to the top of the second sliding plate. A fixing block is rotatably connected to the outer side of the two limiting rods, and a limiting component is fixedly connected to the inside of the auxiliary fixing mechanism. Through the above technical solution: when the extension mechanism is working, it pushes the connecting block, which drives the sliding plate two to slide at the bottom of the auxiliary fixing mechanism, thereby causing the limiting rod to move. The fixing block on the outside of the limiting rod moves with it. Under the action of the limiting component, the fixing block rotates and disengages from its original position. After sliding to the appropriate position, the fixing block is engaged in the corresponding slot of the limiting component under the action of its own elastic element, thus completing the positioning. Through this adjustment, the auxiliary fixing mechanism can be adapted to transformers of different sizes, and the connecting mechanism cooperates to achieve a stable connection.

[0007] Preferably, the limiting component includes a limiting shell, the outer side of which is fixedly connected to the interior of the auxiliary fixing mechanism, and the interior of the limiting shell is provided with multiple limiting grooves; By adopting the above technical solution, in the limiting component, the limiting shell is fixed in the auxiliary fixing mechanism, and multiple limiting grooves inside it are used to cooperate with the fixing block. When the fixing block moves with the sliding, it disengages from the original limiting groove, slides to the corresponding position, and then snaps into the new limiting groove. The multiple grooves achieve fixing at different positions to meet the size adjustment requirements.

[0008] Preferably, the auxiliary fixing mechanism includes a left base plate, the top of which is slidably connected to the bottom of the transformer, two extension blocks are fixedly connected to one side of the left base plate, and a right base plate is slidably connected to one side of the left base plate. By adopting the above technical solution, in the auxiliary fixing mechanism, the left base plate supports the bottom of the transformer, the right base plate slides with the left base plate, and the distance between the right base plate and the left base plate is adjusted to accommodate transformers of different widths. The extension block enhances the structural stability of the left base plate, and the left and right base plates jointly support and assist in fixing the transformer.

[0009] Preferably, the connecting mechanism includes a sliding plate, the outer side of which is slidably connected to the inside of the left bottom plate, and a limiting block is fixedly connected to the outer side of the sliding plate. By adopting the above technical solution, in the connecting mechanism, the sliding plate slides inside the left base plate, driving the limiting block to move. By adjusting the position of the sliding plate, the limiting block is brought close to the transformer, and cooperates with the right base plate to clamp the transformer from both sides, thereby achieving a stable connection for transformers of different widths and enhancing the fixing effect.

[0010] Preferably, the transformer has a slot inside, and a spring is fixedly connected to the inner side of the sliding plate. By adopting the above technical solution, the transformer slot and the connecting mechanism work together. Spring 1 pushes sliding plate 1, causing the limiting block to be inserted into the slot. The elasticity of spring 1 ensures that the limiting block fits tightly against the inner wall of the slot, which not only realizes the quick connection between the transformer and the left base plate, but also compensates for minor size differences through elasticity, thereby enhancing the stability of the fixation.

[0011] Preferably, the outer side of the sliding plate is slidably connected to the inside of the slot, and the limiting block slides inside the slot; By adopting the above technical solution, the sliding plate slides in the slot, driving the limiting block to move synchronously in the slot. By adjusting the position through sliding, the limiting block and the slot are adapted to engage. Combined with the elastic force of the spring, the limiting block is tightly embedded in the slot, constraining the transformer from the inside and enhancing the connection stability with the auxiliary fixing mechanism.

[0012] Preferably, the outer side of the second sliding plate is slidably connected to the inside of the limiting shell, and the end of the second sliding plate away from the connecting block is fixedly connected to the inside of the right bottom plate; By adopting the above technical solution, the sliding plate 2 slides inside the limiting shell, driving the right bottom plate to move to adjust the distance between it and the left bottom plate. When sliding, the sliding plate 2 is subjected to force through the connecting block, and its end is fixed to the right bottom plate, so that the right bottom plate moves synchronously with the sliding plate 2. It is used in conjunction with the internal structure of the limiting shell to achieve positioning and adapt to transformers of different sizes.

[0013] Preferably, the outer side of the fixing block is slidably connected to the inside of the limiting shell, and a second spring is fixedly connected inside the fixing block; By adopting the above technical solution, the fixed block slides inside the limiting shell. When the second spring provides elastic force to make it move against the inner wall of the limiting shell, the fixed block is pressed away from the original limiting groove. After sliding to the new groove, the second spring pushes it to lock in, thereby positioning the second sliding plate and fixing the position of the right bottom plate to adapt to transformers of different sizes.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. In this utility model, by using a connecting block in conjunction with a sliding plate, a sliding plate in conjunction with a limiting rod, a limiting rod in conjunction with a fixing block, a fixing block in conjunction with a limiting shell, and a limiting shell in conjunction with a limiting groove, the distance between the left and right base plates can be adjusted to accommodate transformers of more sizes. With mechanical linkage and a multi-position locking mechanism, it can flexibly adjust and adapt to transformers of various sizes, reduce the cost of special tooling and meet diverse needs, and achieve quick operation without tools, reducing manual difficulty and time costs.

[0015] 2. In this utility model, by using a limiting block, which in turn works with a spring and a slot, the connection between the transformer and the auxiliary fixing structure is achieved. No tools are required and the assembly and disassembly can be completed quickly through simple operation, which greatly improves work efficiency and lowers the operating threshold. At the same time, the elastic preload of the spring and the multi-point limiting design ensure a stable connection and effectively guarantee the glue potting accuracy. Attached Figure Description

Detailed Implementation

[0017] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0018] Example: A transformer potting auxiliary fixing structure, referring to... Figure 1 , Figure 4 and Figure 5The structure includes a transformer 1, which is the core component of the entire structure. The stability of the transformer 1 directly affects the potting effect and requires precise positioning through an auxiliary fixing mechanism 2. The transformer 1 has a slot 34 inside, which provides a locking point for the connecting mechanism 3, allowing the connecting mechanism 3 to form a mechanical lock with the transformer 1 and preventing the transformer 1 from shifting during potting. The bottom of the transformer 1 is slidably connected to the auxiliary fixing mechanism 2. This slidable connection allows the transformer 1 to be placed stably on the auxiliary fixing mechanism 2. At the same time, the auxiliary fixing mechanism 2 provides bottom support for the transformer 1, ensuring its stable placement. The auxiliary fixing mechanism 2 is slidably connected to the connecting mechanism 3 inside. The connecting mechanism 3 can slide and adjust its position within the auxiliary fixing mechanism 2, thereby precisely aligning with the slot 34 of the transformer 1 to achieve the adaptation and fixing of transformers 1 of different sizes. The bottom of the auxiliary fixing mechanism 2 is slidably connected to an extension mechanism 4. The extension mechanism 4, through sliding cooperation with the auxiliary fixing mechanism 2, can change the overall support range of the auxiliary fixing mechanism 2 to accommodate larger transformers 1. Specifically, the core component transformer 1 needs to be positioned by the auxiliary fixing mechanism 2. Its internal slot 34 cooperates with the connecting mechanism 3 to form a mechanical lock to prevent displacement during glue filling. The bottom of the transformer 1 is slidably connected to the auxiliary fixing mechanism 2 for easy placement and stable support. The connecting mechanism 3 can slide within the auxiliary fixing mechanism 2 to accurately align with the slot 34 and adapt to transformers 1 of different sizes. The extension mechanism 4 at the bottom of the auxiliary fixing mechanism 2 changes its support range by sliding to accommodate larger transformers 1, thus achieving stable fixation of the transformer 1 as a whole.

[0019] The extension mechanism 4 includes a connecting block 41, which is the starting point for power transmission. Operating the connecting block 41 can drive other components of the extension mechanism 4 to adjust the size. The top of the connecting block 41 is slidably connected to the bottom of the auxiliary fixing mechanism 2. This slidable connection ensures that the connecting block 41 can smoothly drive the movement of subsequent components, making the adjustment process of the extension mechanism 4 smooth and avoiding jamming that affects operation. A second sliding plate 42 is fixedly connected to the top of the connecting block 41. The movement of the connecting block 41 can be directly transmitted to the second sliding plate 42, causing the second sliding plate 42 to move synchronously, providing power for the size expansion of the auxiliary fixing mechanism 2. Two limiting rods 43 are fixedly connected to the top of the second sliding plate 42. The movement of the second sliding plate 42 will drive the limiting rods 43 to move synchronously, providing support for the fixing block 44. The mounting and rotation fulcrum ensures that the fixing block 44 can function properly. The two limiting rods 43 are rotatably connected to the outer side of the fixing block 44. The fixing block 44 can rotate around the limiting rod 43, which facilitates disengagement or engagement with the limiting component 46 during adjustment, thereby locking and unlocking the position of the extension mechanism 4. The fixing block 44 is internally fixedly connected to the second spring 45, which provides elastic force to the fixing block 44, ensuring that the fixing block 44 is tightly engaged with the limiting component 46 when there is no external interference, thus maintaining the fixed state of the extension mechanism 4. The auxiliary fixing mechanism 2 is internally fixedly connected to the limiting component 46, which provides multiple engagement positions for the fixing block 44. By cooperating with the fixing block 44, the adjustment range of the extension mechanism 4 can be locked in segments, thereby realizing multi-level size adjustment of the auxiliary fixing mechanism 2. Specifically, the connecting block 41 serves as the starting point for power transmission. By operating the connecting block 41, other components are linked to achieve size adjustment. The sliding connection between the connecting block 41 and the auxiliary fixing mechanism 2 ensures smooth adjustment. The connecting block 41 drives the sliding plate 42 to move synchronously, providing power for the size expansion of the auxiliary fixing mechanism 2. The limiting rod 43 on the sliding plate 42 moves with it, providing a mounting and rotation fulcrum for the fixing block 44. The fixing block 44 can rotate around the limiting rod 43. With the elastic force of the internal spring 45, it can disengage from or engage with the limiting component 46. The limiting component 46 provides multiple engagement positions, which, in conjunction with the fixing block 44, realize the segmented locking of the adjustment range of the extension mechanism 4, thereby achieving multi-level size adjustment of the auxiliary fixing mechanism 2.

[0020] The limiting component 46 includes a limiting shell 461, which is the main structure of the limiting component 46. The limiting shell 461 provides installation and sliding space for the fixed block 44 and the sliding plate 42, and is the basis for achieving position locking. The outer side of the fixed block 44 is slidably connected to the inside of the limiting shell 461. This slidable connection allows the fixed block 44 to move within the limiting shell 461, facilitating the switching of the locking state in conjunction with the position changes of the sliding plate 42. The outer side of the sliding plate 42 is also slidably connected to the inside of the limiting shell 461. The sliding of the sliding plate 42 within the limiting shell 461 is guided and constrained, ensuring its movement is controlled. To ensure stability and smooth extension of the component, the outer side of the limiting shell 461 is fixedly connected to the inside of the auxiliary fixing mechanism 2. This fixed connection makes the limiting shell 461 and the auxiliary fixing mechanism 2 form an integral whole, ensuring the stability of the limiting component 46 during adjustment and providing a reliable locking basis for the fixing block 44. The limiting shell 461 has multiple limiting grooves 462 inside, which provide different locking positions for the fixing block 44. By cooperating with the fixing block 44, different extension lengths of the sliding plate 42 can be locked to meet the adaptation requirements of transformers 1 of different sizes. Specifically, the limiting shell 461 serves as the main body, providing installation and sliding space for the fixed block 44 and the second sliding plate 42, and is the basis for position locking. The fixed block 44 slides within the limiting shell 461, and can switch the locking state in coordination with the position change of the second sliding plate 42. The second sliding plate 42 slides within the limiting shell 461 under the guidance constraint, ensuring the smooth extension of the component. The limiting shell 461 is fixedly connected to the auxiliary fixing mechanism 2, ensuring position stability during adjustment and providing a reliable locking basis for the fixed block 44. Multiple limiting grooves 462 inside provide different engagement positions for the fixed block 44, and through cooperation, lock the second sliding plate 42 at different extension lengths to meet the adaptation requirements of transformers 1 of different sizes.

[0021] The auxiliary fixing mechanism 2 includes a left base plate 21, which is one of the basic load-bearing components of the auxiliary fixing mechanism 2. It provides left-side support for the transformer 1 and is the core support structure for achieving overall fixing. The top of the left base plate 21 is slidably connected to the bottom of the transformer 1. This sliding connection allows the transformer 1 to move and adjust its position smoothly on the top of the left base plate 21, facilitating quick alignment with the fixing point and improving installation efficiency. Two extension blocks 23 are fixedly connected to one side of the left base plate 21. The two extension blocks 23 enhance the structural stability of the left base plate 21 and also help to restrict the left base plate 21 from the right base plate. The relative sliding range of plate 22 avoids excessive sliding that could lead to structural misalignment. The left bottom plate 21 is slidably connected to the right bottom plate 22 on one side. The sliding fit between the left bottom plate 21 and the right bottom plate 22 can be adjusted to accommodate transformers 1 of different widths, thus expanding the applicability of the auxiliary fixing mechanism 2. The end of the sliding plate 22 away from the connecting block 41 is fixedly connected to the inside of the right bottom plate 22. This fixed connection allows the movement of the sliding plate 22 to directly drive the right bottom plate 22 to move synchronously, achieving precise adjustment of the distance between the right bottom plate 22 and the left bottom plate 21, and ensuring stable support for the transformer 1. Specifically, the left base plate 21 serves as the basic load-bearing component, providing left-side support for the transformer 1. Its top is slidably connected to the transformer 1, facilitating the adjustment of the transformer 1's position to quickly align with the fixed point. The two extension blocks 23 on one side of the left base plate 21 enhance structural stability and limit the sliding range of the left and right base plates 22, preventing misalignment. The left base plate 21 and right base plate 22 are slidably connected, and their spacing can be adjusted to accommodate transformers 1 of different widths, expanding the applicable range. The sliding plate 42 is fixedly connected to the right base plate 22, and its movement can drive the right base plate 22 to move synchronously, achieving precise adjustment of the spacing between the left and right base plates 22 and ensuring stable support for the transformer 1.

[0022] Reference Figures 1 to 3The connecting mechanism 3 includes a sliding plate 31, which is the main component of the connecting mechanism 3. The sliding plate 31 slides to achieve the engagement between the connecting mechanism 3 and the transformer 1 and the left base plate 21, providing a foundation for fixing the transformer 1. The outer side of the sliding plate 31 is slidably connected to the inside of the slot 34. This sliding connection allows the sliding plate 31 to move within the slot 34, facilitating position adjustment to fit the transformer 1 and enhancing the fit between the connecting mechanism 3 and the transformer 1. A spring 33 is fixedly connected to the inner side of the sliding plate 31. The spring 33 provides elastic force to the sliding plate 31, pushing it and its components to fit tightly against the transformer 1, ensuring the stability of the connection. The outer side of sliding plate 31 is slidably connected to the inside of the left base plate 21. The sliding of sliding plate 31 within the left base plate 21 can adjust its position relative to the left base plate 21, thereby adapting to transformers 1 of different sizes and improving the adaptability of the connection mechanism 3. A limiting block 32 is fixedly connected to the outer side of sliding plate 31. The limiting block 32 moves with sliding plate 31 and, through cooperation with slot 34, further enhances the constraint of the connection mechanism 3 on transformer 1, preventing transformer 1 from shaking. The limiting block 32 slides inside slot 34. The sliding of the limiting block 32 within slot 34 facilitates position adjustment during installation and ensures close contact with the inner wall of slot 34 after fixing, providing a reliable limiting effect for transformer 1. Specifically, the sliding plate 31 serves as the main body, and its sliding action allows it to cooperate with the transformer 1 and the left base plate 21, laying the foundation for fixing the transformer 1. Its outer side is slidably connected to the slot 34 and the left base plate 21, and its position can be adjusted to adapt to transformers 1 of different sizes, enhancing fit and adaptability. The inner spring 33 provides elastic force to push the sliding plate 31 and its components to fit tightly against the transformer 1, ensuring a stable connection. The limiting block 32 on the outer side of the sliding plate 31 moves with it and slides within the slot 34, which facilitates installation and adjustment, and allows it to make close contact with the inner wall of the slot 34, enhancing the constraint on the transformer 1, preventing shaking, and providing reliable positioning.

[0023] Working principle: When the operator needs to connect the transformer 1 to the left base plate 21 and the right base plate 22, the multiple sliding plates 31 connected to the top of the left base plate 21 and the right base plate 22 are pressed inward, causing the limiting block 32 connected to the other end of the sliding plate 31 to move inward. When the two limiting blocks 32 are close, the transformer 1 can be slid downward. The transformer 1 has a slot 34 inside. When the limiting block 32 slides into the slot 34, the sliding plate 31 can be released. At this time, the sliding plate 31 will be pushed outward by the spring 33 on its inner side, causing the limiting block 32 to slide into the slot 34, thereby achieving the connection effect of the transformer 1.

[0024] When the size of transformer 1 is large and does not match the existing auxiliary fixing structure, the connecting block 41 can be pushed forward, so that the connecting block 41 drives the bottom sliding plate 42 forward, thereby pushing the right bottom plate 22 outward. When the sliding plate 42 moves, it will drive the two fixing blocks 44 at the top together. When the fixing block 44 slides inside the limiting groove 462 and is squeezed on one side, it will rotate backward, so that the side inside the limiting groove 462 will disengage from the inside of the limiting groove 462. The limiting shell 461 has multiple limiting grooves 462 inside. When the fixing block 44 slides to the outside of the next limiting groove 462, it will be pushed into the limiting groove 462 by the spring 45, thereby achieving the effect of fixing the right bottom plate 22 after it is extended to the appropriate position.
