Description

Technical Field

[0001] This utility model relates to the field of iron core device technology, specifically a detachable and modular iron core device that is easy to maintain. Background Technology

[0002] In the field of electrical equipment, this device for fixing and maintaining iron cores is a crucial component for ensuring stable equipment operation. Through its unique mechanical structure design, it achieves secure fixing of the iron core and convenient disassembly, and is widely used in transformers, motors, and other equipment that relies on iron cores for operation. Its core function is to ensure the iron core maintains a stable position during equipment operation, preventing performance degradation due to displacement. Simultaneously, it allows for quick and safe disassembly of the iron core when equipment requires maintenance, ensuring long-term reliable operation and efficient maintenance of the equipment.

[0003] Traditional methods of securing and maintaining iron cores have numerous drawbacks. Previous methods primarily relied on bolts or adhesive bonding, which were not only cumbersome and time-consuming to install, but also prone to loosening due to vibration during equipment operation, and causing the adhesive to lose its stickiness as it ages, leading to core misalignment and disrupting normal equipment operation. During maintenance, bolt removal was difficult, and glued cores required forceful separation with tools, which was not only complex but also highly susceptible to damage to the core or the equipment casing. These problems render traditional iron core securing and maintenance methods inefficient and unreliable, failing to meet the requirements of modern electrical equipment for convenient maintenance and stable operation. Utility Model Content

[0004] One of the technical problems this application aims to solve is that existing iron core devices are fastened with bolts or glued together, which is not only cumbersome and time-consuming during installation and maintenance, but also prone to loosening due to vibration during equipment operation, and the glue loses its adhesiveness due to aging, resulting in damage to the iron core or equipment casing.

[0005] To address the aforementioned technical problems, this application provides a detachable and easily maintainable iron core device, comprising a solenoid valve body. A housing is fixedly connected to both outer walls of the solenoid valve body. A sliding groove is formed on the outer wall of the housing, and a return spring is movably connected to the outer wall of the sliding groove. Multiple retaining beads are arranged in a circular array on the sliding groove. A movable block is movably connected to one outer wall of the housing, and a protrusion is fixedly connected to one side of the inner wall of the movable block. A limiting block is movably connected to one side of the inner wall of the housing, and a retaining groove is formed on one side of the outer wall of the limiting block.

[0006] In some embodiments, an electromagnetic coil is connected to one side of the inner wall of the housing, and a connector is movably connected to one side of the inner wall of the solenoid valve body, with an iron core body movably connected to both ends of the connector.

[0007] In some embodiments, the two iron core bodies are respectively disposed on one side of the inner wall of the housing provided on both sides of the solenoid valve body.

[0008] In some embodiments, one side of the outer wall of the limiting block is movably connected to one side of the inner wall of the housing, and the slot opened on one side of the outer wall of the limiting block engages with the ring array of beads on the slide groove.

[0009] In some embodiments, a protrusion on one side of the inner wall of the movable block is correspondingly connected to a groove on the outer wall of the housing.

[0010] In some embodiments, a protrusion on one side of the inner wall of the movable block is connected to a plurality of locking beads in a ring array on the slide groove.

[0011] In some embodiments, the iron core body provided on one side of the inner wall of the housing is located near the electromagnetic coil provided on the same side of the inner wall of the housing.

[0012] In some embodiments, one end of the limiting block connected to one side of the inner wall of the housing is correspondingly connected to the iron core body provided on one side of the inner wall of the housing.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. In use, this utility model utilizes a limiting block and a retaining ball set on the inner wall of the housing, combined with the action of a return spring. The limiting block effectively fixes the iron core body to the inner wall of the housing, preventing unnecessary displacement and ensuring stable operation of the iron core. Through the cooperative design of the sliding groove and the retaining slot, when the movable block is slid outward, the return spring pushes the protrusion, causing the retaining ball to lose its compressive force and disengage from the retaining slot, thereby separating the limiting block from the inner wall of the housing. This allows for easy removal of the iron core body, achieving disassembly and convenient maintenance of the equipment.

[0015] 2. In use, the coordinated design of the housing, movable block, protrusion, and limiting block allows the limiting block to engage or disengage with the locking bead at the appropriate time, achieving precise positioning of the iron core body. By adjusting the force of the protrusion applied by the return spring, the entire device can achieve dynamic limiting and reliable locking, preventing arbitrary displacement of the iron core body and ensuring the reliability and accuracy of the system during operation.

[0016] 3. In use, within the solenoid valve body, the electromagnetic coil and the iron core body work together to drive the iron core body to offset within the inner wall of the housing through electromagnetic effect. The iron core body is connected to the connecting piece; when one side of the iron core body is driven by the electromagnetic coil, the connecting piece will be linked with the other side of the iron core body, thereby generating reciprocating motion and performing hydraulic operation, ensuring that the hydraulic system can complete its work accurately and efficiently.

[0022] 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.

[0023] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a detachable and easily maintainable iron core device, including a solenoid valve body 1, with a housing 2 fixedly connected to both outer walls of the solenoid valve body 1. A slide groove 6 is provided on the outer wall of the housing 2, and a return spring 7 is movably connected to the outer wall of the slide groove 6. Multiple retaining beads 8 are arranged in a ring on the slide groove 6. A movable block 9 is movably connected to one outer wall of the housing 2, and a protrusion 10 is fixedly connected to one side of the inner wall of the movable block 9. The protrusion 10 on one side of the inner wall of the movable block 9 is correspondingly connected to the slide groove 6 on the outer wall of the housing 2. The protrusion 10 on one side of the inner wall of the movable block 9 is correspondingly connected to the multiple retaining beads 8 arranged in a ring on the slide groove 6. A limiting block 11 is movably connected to one side of the inner wall of the housing 2. The outer wall of one side of the limiting block 11 is movably connected to one side of the inner wall of the housing 2, and a retaining groove 12 is provided on one side of the outer wall of the limiting block 11 and engages with the retaining beads 8 arranged in a ring on the slide groove 6. A retaining groove 12 is provided on one side of the outer wall of the limiting block 11.

[0024] In this embodiment, a solenoid valve body 1 is designed, and a housing 2 is fixedly connected to the outer walls of both sides of the solenoid valve body 1. A groove 6 is formed on one outer wall of the housing 2, and a return spring 7 is connected to one side of the outer wall of the groove 6. On the other side of the groove 6, a slot is formed and multiple retaining beads 8 are arranged in a circular array. The retaining beads 8 are close to the side of the return spring 7. A movable block 9 is slidably connected to one outer wall of the housing 2. A protrusion 10 is fixedly connected to one side of the inner wall of the movable block 9. The protrusion 10 can be connected to the groove 6 formed on the outer wall of the housing 2, and one side of the outer wall of the protrusion 10 is fixedly connected to one end of the return spring 7. A limiting block 11 is movably connected to one side of the inner wall of the housing 2, and a groove 12 is formed on one side of the outer wall of the limiting block 11. One end of the limiting block 11 can extend to one side of the inner wall of the housing 2. Furthermore, the slot 12 can be connected to the corresponding bead 8. Therefore, when the limiting block 11 is connected to one side of the inner wall of the housing 2, the force exerted by the return spring 7 on the protrusion 10 can make the protrusion 10 move left and right with the bead 8, thereby making the bead 8 engage with the slot 12. This allows the limiting block 11 to be fixed to one side of the inner wall of the housing 2, thus limiting the movement of the iron core body 5 on one side of the inner wall of the housing 2. Conversely, when the movable block 9 is slid towards the outer wall of the housing 2, the protrusion 10 can squeeze the return spring 7. At this time, the bead 8 loses the external squeezing force and will leave the slot 12. At this time, the limiting block 11 can be pulled out from one side of the inner wall of the housing 2, thereby allowing the iron core body 5 connected to one side of the inner wall of the housing 2 to be removed, thus completing the function of disassembly and maintenance.

[0025] Example 2: Please refer to Figure 1-2 An electromagnetic coil 3 is connected to one side of the inner wall of the housing 2, and a connector 4 is movably connected to one side of the inner wall of the solenoid valve body 1. An iron core body 5 is movably connected to both ends of the connector 4. The two iron core bodies 5 are respectively located on one side of the inner wall of the housing 2 on both sides of the solenoid valve body 1. The iron core body 5 located on one side of the inner wall of the housing 2 is close to the side of the electromagnetic coil 3 located on the inner wall of the housing 2. The end of the limiting block 11 connected to one side of the inner wall of the housing 2 is correspondingly connected to the iron core body 5 located on one side of the inner wall of the housing 2.

[0026] In this embodiment, an electromagnetic coil 3 is provided on one side of the inner wall of the housing 2, and an iron core body 5 is located close to the inner wall of the electromagnetic coil 3. When the electromagnetic coil 3 exerts an electromagnetic effect, it can drive the iron core body 5 to deflect on the inner wall of the housing 2. A connector 4 is connected to one side of the iron core body 5, and the connector 4 is movably connected to one side of the inner wall of the solenoid valve body 1. There are two iron core bodies 5, which are respectively located on one side of the inner wall of the housing 2 and on both sides of the connector 4. Therefore, when one iron core body 5 is subjected to the electromagnetic effect of the electromagnetic coil 3, it will cause the iron core body 5 to act on the connector 4, so that the connector 4 connects to the iron core body 5 on the other side. Conversely, it can cause the other iron core body 5 to act, thereby performing reciprocating motion and hydraulic operation. A limit block 11 is connected to one side of the iron core body 5, which can limit the iron core body 5, so that it can slide stably on one side of the inner wall of the housing 2.

[0027] like Figure 1-4 As shown, the core principle of this device is based on the coordinated operation of electromagnetic force drive and mechanical limit mechanism. Combined with components such as electromagnetic coil 3, iron core body 5, locking ball 8, and return spring 7, it realizes precise control and safe maintenance of hydraulic system.

[0028] First, the device includes a solenoid valve body 1, with housings 2 fixed to its outer walls on both sides. A groove 6 is provided on one side of housing 2, and one side of the inner wall of the groove 6 is connected to a return spring 7. On the other side of the groove 6, multiple retaining beads 8 are provided on the outer wall of housing 2, arranged in a circular array. The main function of these retaining beads 8 is to cooperate with the retaining grooves 12 of the limiting block 11 to fix the limiting block 11. The retaining beads 8 are located near the return spring 7. When the retaining beads 8 are connected to the retaining grooves 12, the limiting block 11 can be firmly fixed to the inner wall of housing 2.

[0029] The function of the limiting block 11 is to restrict the movement trajectory of the iron core body 5 and ensure the stability of the iron core sliding on the inner wall of the housing 2. The slot 12 of the limiting block 11 is tightly engaged with the retaining bead 8. When the limiting block 11 is connected to the inner wall of the housing 2, the retaining bead 8 will lock it, preventing the limiting block 11 from moving further. At this time, the limiting block 11 plays a limiting role for the iron core body 5.

[0030] For ease of operation and disassembly, the device is also designed with a movable block 9, which can slide on the outer wall of the housing 2. The inner wall of the movable block 9 has a protrusion 10, which engages with a groove 6 on the outer wall of the housing 2, allowing it to slide within the groove 6. When the movable block 9 is pushed, the protrusion 10 compresses the return spring 7, causing the return spring 7 to compress and thus releasing the locking bead 8 from the locking groove 12, causing the locking bead 8 to pop out of the locking groove 12. At this point, the limiting block 11 can separate from the inner wall of the housing 2, allowing the operator to easily remove the iron core body 5 for inspection or maintenance.

[0031] An electromagnetic coil 3 is installed on one side of the inner wall of the housing 2 and drives the iron core body 5 to move through electromagnetic effects. The function of the electromagnetic coil 3 is to generate a magnetic field through current, affecting the movement of the iron core body 5. There are two iron core bodies 5. When one iron core body 5 is subjected to electromagnetic force, it pushes the connecting piece 4. The connecting piece 4 is connected to the other iron core body 5, so that the two iron core bodies 5 can move in coordination, forming a reciprocating motion. The connecting piece 4 connects the movements of the two iron core bodies 5, ensuring that they move in coordination in opposite directions, realizing hydraulic operation.

[0032] Each core body 5 is connected to a limiting block 11 on one side. The limiting block 11 can effectively limit the range of motion of the core body 5 and ensure its stable sliding on the inner wall of the housing 2. Through the control of the electromagnetic coil 3, the reciprocating motion of the core body 5 can precisely adjust the working state of the hydraulic system to achieve precise control of the hydraulic fluid.

[0033] In summary, this device drives the reciprocating motion of the iron core body 5 through the electromagnetic action of the electromagnetic coil 3. Combined with the coordinated work of mechanical components such as the retaining ball 8, the return spring 7, and the limit block 11, it ensures the stable operation of the hydraulic system under different working conditions. Meanwhile, the designed movable block 9 and disassembly mechanism allow for convenient maintenance and replacement, increasing the reliability and ease of operation of the equipment.
