Description

Technical Field

[0001] This utility model relates to the field of electrical insulation materials technology, and in particular to a reinforcing structure for an insulating epoxy phenolic glass cloth laminate. Background Technology

[0002] In numerous fields such as electrical equipment manufacturing, electronic instrument assembly, and industrial automation control, insulating epoxy phenolic glass cloth laminates are widely used as a key insulating material for the isolation, support, and protection of various electrical components. With continuous technological development and increasingly diversified application scenarios, higher and higher requirements are being placed on the reinforcement structure of these laminates. Different usage environments and equipment needs have resulted in a diverse range of laminate specifications. In actual production and installation, how to quickly, efficiently, and accurately provide appropriate reinforcement protection for laminates of different specifications has become a crucial technical problem that urgently needs to be solved. This not only relates to the overall performance and stability of electrical equipment but also directly affects production efficiency and cost control.

[0003] Traditional reinforced epoxy phenolic glass cloth laminates typically employ a relatively fixed frame design. For example, a common method is to use welding or riveting to fix a metal frame in place, and the frame's size and shape cannot be easily changed after manufacturing. The technical principle of this mechanical structure is primarily based on rigid connections and fixed dimensions, aiming to provide basic physical support and protection for the laminate, preventing damage from external mechanical impacts, chemical corrosion, and electrical breakdowns. In this traditional design, the various components of the frame lack flexible adjustability, relying entirely on pre-set dimensions and shapes to fit the laminate. Furthermore, the surface protective plate is often secured with numerous screws. While this method ensures a certain level of stability, maintenance, replacement, or adjustment of the surface protective plate requires the use of screwdrivers and other tools to sequentially remove and install numerous screws, making the process cumbersome, time-consuming, and labor-intensive.

[0004] However, this traditional reinforcement structure has significant limitations: it cannot easily accommodate laminates of different specifications. Due to its fixed frame dimensions and lack of flexible adjustment mechanisms, the following problems arise when encountering laminates of different specifications: either the laminates cannot be tightly installed within the reinforcement structure, leading to displacement or shaking during use, affecting their insulation performance and stability; or the entire reinforcement structure needs to be redesigned and remanufactured, which undoubtedly increases production costs and time, reducing production efficiency. In actual production and application, this incompatibility causes numerous inconveniences for enterprises, severely restricts the rapid upgrading and optimization of electrical equipment, and makes it difficult to meet the market's demand for diversified and personalized electrical equipment. Therefore, developing a reinforcement structure that can be easily adjusted to accommodate laminates of different specifications has significant practical importance and market value. To this end, a reinforcement structure for insulating epoxy phenolic glass cloth laminates is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a reinforcing structure for insulating epoxy phenolic glass cloth laminate, aiming to improve the problem that existing technologies cannot easily reinforce and stabilize laminates of different specifications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A reinforcing structure for an insulating epoxy phenolic glass cloth laminate includes four corner protectors and four telescopic components. The corner protectors are connected to each other through the telescopic components. A surface protective plate is provided at the top of each corner protector, and a disassembly and assembly component is provided inside each corner protector. The telescopic assembly includes a telescopic outer shell disposed between the two corner protectors. A movable groove is provided inside the telescopic outer shell. A telescopic rod is slidably connected inside the corner protector. One end of the telescopic rod is fixedly connected to the outer wall of the corner protector, and the other end of the telescopic rod is fixedly connected to a limiting disc. The outer wall of the limiting disc is slidably connected inside the movable groove. A spring is sleeved on the outer wall of the telescopic rod. One end of the spring is fixedly connected to the inner wall of the movable groove, and the other end of the spring is fixedly connected to the outer wall of the limiting disc. As a further description of the above technical solution: The disassembly / assembly assembly includes a locking post, which is disposed on the outer wall of the corner protector. As a further description of the above technical solution: The surface protection plate has a sliding groove inside and a locking groove inside; As a further description of the above technical solution: The outer wall of the card post is slidably connected to the inside of the card slot, and the outer wall of the card post is slidably connected to the inner wall of the sliding groove; As a further description of the above technical solution: A connecting post is fixedly connected to the bottom of the card post, and a limiting groove is opened inside the corner of the wrapping; As a further description of the above technical solution: The outer wall of the connecting column is rotatably connected to a limiting ring, and the outer wall of the limiting ring is slidably connected inside the limiting groove. As a further description of the above technical solution: A second spring is provided inside the corner of the enclosure. The top of the second spring is fixedly connected to the bottom of the limiting ring, and the bottom of the second spring is fixedly connected to the inner wall of the limiting groove.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the telescopic rod achieves its movement function by pulling the wrap corner. When the wrap corner is pulled, the wrap corner drives the spring and the limiting disc and cooperates with the moving groove to realize the sliding of the telescopic rod inside the telescopic shell, thereby conveniently adjusting the internal space to adapt to different specifications of laminates. This solves the problem of not being able to conveniently adapt and place laminates of different specifications, and improves the applicability of the reinforced structure.

[0008] 2. In this utility model, the locking post moves by pulling its surface groove. When the surface groove is pulled, the groove drives the connecting post and the limiting ring, and in conjunction with the second spring, the locking post slides within the sliding groove and the locking groove, thus facilitating the disassembly and assembly of the surface protective plate. This makes it convenient for maintenance and replacement, solving the problem that multiple tools are required for disassembly and assembly in existing systems, which makes disassembly inconvenient. This improves the convenience of disassembling and assembling the surface protective plate. Attached Figure Description

[0011] 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.

[0012] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a reinforced structure for an insulating epoxy phenolic glass cloth laminate, comprising four corner protectors 1 and four telescopic components. The corner protectors 1 are connected to each other by the telescopic components. A surface protection plate 4 is provided on the top of the corner protector 1. The plate is made of high-strength engineering plastic material and has good insulation, wear resistance and corrosion resistance. It can effectively prevent external physical damage and chemical erosion, and ensure the safety of the upper surface of the laminate. The corner protector 1 is provided with a disassembly and assembly component. The telescopic assembly includes a telescopic housing 2, which is positioned between two corner brackets 1. The telescopic housing 2 has a moving groove 8 inside. A telescopic rod 3 is slidably connected inside the corner brackets 1. One end of the telescopic rod 3 is securely welded to the outer wall of the corner bracket 1, ensuring the stability and reliability of the connection. The other end of the telescopic rod 3 is fixedly connected to a limiting disc 9, which is made of stainless steel, possessing high hardness and wear resistance. Its outer wall fits tightly against the inner wall of the moving groove 8 and can slide smoothly, ensuring that the telescopic rod 3 always moves along a predetermined trajectory during telescopic movement. In case of displacement or shaking, the outer wall of the limiting disc 9 is slidably connected to the inside of the moving groove 8. The outer wall of the telescopic rod 3 is fitted with a spring 7. One end of the spring 7 is fixedly connected to the inner wall of the moving groove 8, and the other end of the spring 7 is fixedly connected to the outer wall of the limiting disc 9. With its strong rebound force, the spring 7 can automatically pull the wrapping corner 1 back to its original position, thereby tightly wrapping the laminate, effectively enhancing the strength and stability of the overall structure. This provides comprehensive and reliable reinforcement and protection measures for the insulating epoxy phenolic glass cloth laminate, enabling it to operate stably under various complex working conditions, extending its service life, and ensuring its efficient and safe application in key areas such as electrical insulation.

[0013] Specifically, an innovative adjustable structure is used to reinforce the insulating epoxy phenolic glass cloth laminate. The wrap angle 1 is a movable component; when moved, it drives the connected telescopic rod 3 to move synchronously. The other end of the telescopic rod 3 is connected to a limiting disc 9. Driven by the wrap angle 1, the limiting disc 9 slides within the moving groove 8, compressing the spring 7 and thus stretching the reinforcing structure. The stretched space is sufficient to accommodate the laminate. After the laminate is placed inside, the spring 7's rebound force ensures the reinforcing structure tightly wraps around it, providing stable support and enhancing its overall strength. This effectively improves the laminate's performance under various working conditions, extends its service life, and ensures reliable application in electrical insulation and other fields.

[0014] Reference Figure 1 and Figure 3 The assembly and disassembly components include a locking post 10, which is located on the outer wall of the corner protector 1. A sliding groove 5 is formed inside the surface protection plate 4. The inner wall of the sliding groove 5 undergoes a special process to form a smooth and slightly curved surface. This not only facilitates the smooth sliding of the locking post 10 in and out but also guides and limits its movement to a certain extent. A slot 6 is formed inside the surface protection plate 4, whose size perfectly matches the outer diameter of the locking post 10. This allows the outer wall of the locking post 10 to slide tightly and smoothly into the slot 6, thus achieving a stable connection between the surface protection plate 4 and the corner protector 1. The outer wall of the locking post 10 is slidably connected to the slot 6 and the inner wall of the sliding groove 5. The bottom of the locking post 10 is fixed. A connecting post 11 is fixedly connected, and a limiting groove 13 is opened inside the corner 1. A limiting ring 12 is rotatably connected to the outer wall of the connecting post 11. The limiting ring 12 is made of wear-resistant nylon material. Its outer wall is tightly fitted with the inner wall of the limiting groove 13 and can slide smoothly. At the same time, the inner diameter of the limiting ring 12 is adapted to the outer diameter of the connecting post 11, so that the connecting post 11 can rotate flexibly in the limiting ring 12, thereby providing more convenience and flexibility for the operation of the locking post 10. The outer wall of the limiting ring 12 is slidably connected inside the limiting groove 13. A second spring 14 is provided inside the corner 1. The top of the second spring 14 is fixedly connected to the bottom of the limiting ring 12, and the bottom of the second spring 14 is fixedly connected to the inner wall of the limiting groove 13.

[0015] Specifically, the structure used for reinforcing epoxy phenolic glass cloth laminates of different specifications exhibits good adaptability and operability. When adjusting the existing reinforcing structure to accommodate new laminate specifications, the groove inside the locking post 10 can be used to apply external force to pull the locking post 10. The movement of the locking post 10 will cause the connected post 11 to rise, thereby causing the bottom limiting ring 12 to rise synchronously. During this process, the second spring 14 is gradually stretched, storing elastic potential energy. Subsequently, the locking post 10 is rotated to precisely align it with the sliding groove 5. At this time, due to the rebound effect of the second spring 14, the locking post 10 is quickly slid out from inside the sliding groove 5, thus allowing the originally installed surface protection plate 4 to be removed. Next, a surface protection plate 4 matching the specifications of the new laminate is placed in place and firmly fixed using a corresponding fixing mechanism. This ensures that the surface protection plate 4 can stably play its protective role for the laminate during subsequent use, maintaining the stability and reliability of the entire reinforced structure. This provides precise and effective reinforcement and protection for laminates of different specifications, meeting diverse usage needs.

[0016] Working principle: When reinforcing the laminate, the wrapping corner 1 can be moved, and then the wrapping corner 1 drives the corresponding telescopic rod 3 to move. Then the telescopic rod 3 drives the limiting disc 9 to slide inside the moving groove 8 and compresses the spring 7, so that the reinforcing structure can be stretched. Then the laminate is placed, and the spring 7 rebounds to wrap it, protect it, and enhance the overall strength. In addition, when reinforcing laminates of different specifications, the locking post 10 can be pulled by the groove inside the locking post 10, and then the connecting post 11 is lifted by the locking post 10. Then the bottom limiting ring 12 is lifted by the connecting post 11, thereby pulling the second spring 14. Then the locking post 10 is rotated to align with the sliding groove 5. Then the locking post 10 is pushed out of the sliding groove 5 by the spring 14. Only then can the surface protection plate 4 be removed, and the corresponding surface protection plate 4 is placed and fixed to keep it stable.

[0017] 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.
