Description

Technical Field

[0001] This utility model relates to the field of transformer component technology, and in particular to a stable transformer core that is easy to install. Background Technology

[0002] In the field of transformer manufacturing, the transformer core, as a core component, plays a crucial role in production efficiency and product quality due to the ease and stability of its installation. With the rapid development of power electronics technology, transformers are increasingly widely used in various electronic devices and power systems, which places higher demands on the installation methods of transformer cores. Traditional transformer core installation methods have many drawbacks. For example, the common method of assembling the core body with the frame often involves adhesive bonding and tape wrapping. Adhesive bonding is cumbersome, requiring precise mixing of the adhesive ratio, and the adhesive curing process is time-consuming, severely impacting production efficiency. Moreover, the amount of adhesive used is difficult to control precisely; too much can overflow and contaminate other components, while too little will compromise the connection strength. Tape wrapping also presents problems; workers need to wrap the tape multiple times, consuming a large amount of tape, and the tightness of the wrapping relies entirely on experience, making it difficult to ensure consistency and easily leading to the core not being securely fixed in the frame. Furthermore, when the product needs repair or reassembly, adhesive-bonded cores are difficult to disassemble, and forced disassembly can easily damage the core and frame, leading to component scrap and increased production costs. According to incomplete statistics, the increased defect rate and maintenance costs caused by traditional installation methods have led to a 10%-15% increase in product costs for some transformer manufacturers.

[0003] The inventors believe that the following drawbacks often exist: when workers need to install the frame and the core body, they need to use glue to stick the two core bodies together on the side that is in contact, and they also need to use tape to wrap the two core bodies multiple times. This requires workers to use a variety of tools and a lot of effort and time. At the same time, it is difficult to reassemble and use them, thus increasing the workload of workers and increasing costs. Therefore, in order to solve the above problems, a stable transformer core that is easy to install is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the need for workers to use multiple tools and expend a lot of energy and time, and the difficulty in secondary assembly and use, which increases the workload and cost of workers. Therefore, this invention proposes a stable transformer core that is easy to install.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a stable transformer core that is easy to install, comprising a frame and two core bodies. The frame has square holes on both sides, and the surfaces of the two square holes in the frame are slidably connected to the two core bodies respectively. An L-shaped plate is fixedly connected to the upper surface of the core body, and the surface of the L-shaped plate is slidably connected to the frame. Two fixing rods are fixedly connected to the upper surface of the frame, and an operating plate is slidably connected to the arc surface of the fixing rods. An insertion rod is fixedly connected to one side of the operating plate, and an insertion hole is formed on the surface of the L-shaped plate.

[0006] The aforementioned components achieve the following effect: they enable rapid assembly and installation of the frame and the magnetic core body, avoiding the need for workers to glue the two magnetic core bodies together on the contact side and repeatedly wrap them with tape when installing the frame and the magnetic core body. This avoids the need for workers to use multiple tools and spend a lot of time and energy, and makes it difficult to reassemble and use the equipment, thus increasing the workload and cost of workers and improving the practicality of the device.

[0007] Preferably, a limiting plate is fixedly connected to the end of the fixing rod away from the frame, and the size of the insertion rod is adapted to the size of the L-shaped plate insertion hole.

[0008] The effect achieved by the above components is that the limiting plate restricts the maximum sliding distance of the operating plate on the arc surface of the fixed rod, thus preventing the operating plate from detaching from the arc surface of the fixed rod due to excessive pulling force when the operator pulls the operating plate.

[0009] Preferably, the arc surface of the fixing rod is fitted with a first spring, and the two ends of the first spring are fixedly connected to the operating plate and the frame, respectively.

[0010] The effect achieved by the above components is that the first spring improves the stability of the insertion rod when it is positioned relative to the L-shaped plate, thereby improving the stability of the insertion rod when it is positioned relative to the magnetic core body.

[0011] Preferably, a rubber ring is fixedly connected to the surface of the operating panel, and the rubber ring is slidably connected to the arc surface of the fixing rod.

[0012] The effect achieved by the above components is that the binding force of the rubber ring wraps around the arc surface of the fixed rod, thereby slowing down the movement speed of the control panel on the arc surface of the fixed rod, and reducing the occurrence of the control panel sliding unintentionally due to external shaking, thus playing a role in indirect damping.

[0013] Preferably, four sliding rods are slidably inserted into the frame, the four sliding rods are in pairs, and strip plates are fixedly connected to the ends of the two pairs of sliding rods that are close to each other. A square plate is fixedly connected to one side of the strip plate. A second spring is sleeved on the arc surface of the sliding rod. The two ends of the second spring are fixedly connected to the frame and the strip plate respectively. The square plate abuts against one side of the L-shaped plate.

[0014] The aforementioned components achieve the following effect: automatically removing the L-shaped plate from the frame, thereby reducing the number of steps required for operators to use the device and improving their work efficiency.

[0015] Preferably, a semi-circular plate is fixedly connected to both sides of the skeleton, and the upper surface of the semi-circular plate is slidably connected to the magnetic core body.

[0016] The effect achieved by the above components is that the semi-circular plate supports the magnetic core body, thereby dispersing the force on the L-shaped plate and preventing the L-shaped plate from breaking.

[0017] Preferably, the surfaces of the two magnetic core bodies are slidably connected by a restraining sleeve, the restraining sleeve being made of rubber.

[0018] The effects achieved by the above components are as follows: the binding sleeve further tightens the connection between the magnetic core body and the frame, improving the overall stability of the device, while the rubber binding sleeve can play a certain role in insulation and anti-collision.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] This invention achieves the effect of quick assembly and installation of the frame and the magnetic core body, avoiding the need for workers to glue the two magnetic core bodies together on the contact side and wrap them with tape multiple times when installing the frame and the magnetic core body. This requires workers to use multiple tools and spend a lot of energy and time, and it is difficult to reassemble and use them, thus increasing the workload of workers and increasing costs. This invention improves the practicality of the device. Attached Figure Description

[0026] Reference Figure 1-4As shown, this utility model provides a technical solution: a stable transformer core that is easy to install, including a frame 1 and two core bodies 2. Square holes are provided on both sides of the frame 1, and the surfaces of the square holes of the two frame 1 are slidably connected to the two core bodies 2 respectively. An L-shaped plate 3 is fixedly connected to the upper surface of the core body 2, and the surface of the L-shaped plate 3 is slidably connected to the frame 1. Two fixing rods 4 are fixedly connected to the upper surface of the frame 1, and an operating plate 5 is slidably connected to the arc surface of the fixing rods 4. An insertion rod 6 is fixedly connected to one side of the operating plate 5. Insertion holes are provided on the surface of the L-shaped plate 3. When the operator needs to quickly assemble and install the frame 1 and the core bodies 2, the two core bodies 2 are inserted into the square holes of the two frame 1 respectively until one side of the two core bodies 2 is in contact with the frame. When the control panel 5 is pressed, it slides on the arc surface of the fixed rod 4, simultaneously moving the insertion rod 6 until it is inserted into the socket of the L-shaped plate 3. This achieves the effect of quickly assembling and installing the frame 1 and the magnetic core body 2, avoiding the need for workers to glue the two magnetic core bodies 2 together on the contact side and wrap them with tape multiple times when installing the frame 1 and the magnetic core body 2. This requires workers to use multiple tools and spend a lot of time and effort, and makes secondary assembly difficult, thus increasing the workload and cost of workers. This improves the practicality of the device. The end of the fixed rod 4 away from the frame 1 is fixedly connected to the limiting plate 7, and the insertion rod 6... The dimensions of the operating plate 5 are matched with the dimensions of the L-shaped plate 3 insertion hole. When the operator pulls the operating plate 5, the operating plate 5 slides on the arc surface of the fixed rod 4. At this time, the limiting plate 7 achieves the effect of limiting the maximum sliding distance of the operating plate 5 on the arc surface of the fixed rod 4, avoiding the situation where the operating plate 5 detaches from the arc surface of the fixed rod 4 due to excessive pulling force. The arc surface of the fixed rod 4 is fitted with a first spring 8, and the two ends of the first spring 8 are fixedly connected to the operating plate 5 and the frame 1 respectively. When the operator releases the operating plate 5, the rebound force of the first spring 8 drives the operating plate 5 to slide on the arc surface of the fixed rod 4. At the same time, the operating plate 5 drives the insertion rod 6 to move until the insertion rod 6 is inserted into the insertion hole of the L-shaped plate 3. At this time, the first spring 8 raises the insertion rod. The stability of the L-shaped plates 3 when they are limited is improved, thereby improving the stability of the insertion rod 6 when it is limited to the magnetic core body 2. A rubber ring 9 is fixedly connected to the surface of the operating plate 5. The rubber ring 9 is slidably connected to the arc surface of the fixing rod 4. When the operating plate 5 is moved, the binding force of the rubber ring 9 wraps around the arc surface of the fixing rod 4, thereby slowing down the movement speed of the operating plate 5 on the arc surface of the fixing rod 4. At the same time, it reduces the occurrence of the operating plate 5 sliding unintentionally due to external shaking, thus playing a role in damping. Four sliding rods 10 are slidably inserted in the frame 1. The four sliding rods 10 are in pairs. The ends of the two pairs of sliding rods 10 that are close to each other are fixedly connected to strip plates 12. A square plate 13 is fixedly connected to one side of the strip plate 12. A second spring 11 is sleeved on the arc surface of the sliding rod 10.The two ends of the second spring 11 are fixedly connected to the frame 1 and the strip plate 12, respectively. The square plate 13 abuts against one side of the L-shaped plate 3. When the operator releases the limiting force of the insertion rod 6 on the L-shaped plate 3, the rebound force of the second spring 11 drives the strip plate 12 to move, the strip plate 12 drives the square plate 13 to move, and the square plate 13 drives the L-shaped plate 3 to slide inside the frame 1 until the L-shaped plate 3 disengages from the frame 1. This achieves the effect of automatically removing the L-shaped plate 3 from the frame 1, thereby reducing the operator's steps and improving the operator's work efficiency. The frame 1 has semicircular plates 14 fixedly connected to both sides. The upper surface of the semicircular plates 14 is slidably connected to the magnetic core body 2. The semicircular plates 14 support the magnetic core body 2, thereby distributing the force on the L-shaped plate 3 and preventing it from breaking. Binding sleeves 15, made of rubber, are slidably connected to the surfaces of the two magnetic core bodies 2. The binding sleeves 15 further tighten the connection between the magnetic core body 2 and the frame 1, improving the overall stability of the device. Simultaneously, the rubber binding sleeves 15 provide a certain degree of insulation and impact protection.

[0027] Working principle: During operation, when the operator wants to quickly assemble the frame 1 and the magnetic core body 2, first insert the two magnetic core bodies 2 into the square holes on both sides of the frame 1 until they are in contact on one side. Then, press the operating plate 5. The operating plate 5 slides on the arc surface of the fixing rod 4 under external force. During this process, the limiting plate 7 limits the maximum sliding distance of the operating plate 5 to prevent it from detaching from the fixing rod 4. At the same time, the operating plate 5 drives the insertion rod 6 to move until the insertion rod 6 is accurately inserted into the insertion hole of the L-shaped plate 3, completing the initial rapid assembly of the frame 1 and the magnetic core body 2. During this period, the first spring 8 sleeved on the arc surface of the fixing rod 4 is compressed when the operating plate 5 is pulled. When the operating plate 5 is released, the rebound force of the first spring 8 drives the operating plate 5 to slide in the opposite direction, further ensuring that the insertion rod 6 is firmly inserted into the insertion hole of the L-shaped plate 3, improving the limiting stability of the L-shaped plate 3 and the magnetic core body 2. In addition, the rubber ring 9 on the surface of the operating plate 5 wraps around the arc surface of the fixing rod 4 with binding force during the sliding process, slowing down the movement speed of the operating plate 5. The design reduces unintentional slippage caused by external shaking, providing a damping effect. If disassembly is required later, the staff releases the limiting force of the insertion rod 6 on the L-shaped plate 3. At this time, the second spring 11 located in the frame 1 starts to act due to the rebound force generated by the previous compression, driving the strip plate 12 to move. The strip plate 12 pushes the square plate 13, and the square plate 13 in turn drives the L-shaped plate 3 to slide within the frame 1 until the L-shaped plate 3 detaches from the frame 1, thus automatically removing the L-shaped plate 3 from the frame 1, reducing operation steps and improving work efficiency. In addition, the semi-circular plates 14 fixed on both sides of the frame 1 slide to the magnetic core body 2 after the magnetic core body 2 is installed, supporting the magnetic core body 2, dispersing the force on the L-shaped plate 3, and preventing the L-shaped plate 3 from breaking. The rubber restraint sleeves 15 fitted on the surfaces of the two magnetic core bodies 2 not only make the magnetic core body 2 more tightly connected to the frame 1, improving the overall stability of the device, but also have an insulating and anti-collision effect due to the rubber material, further ensuring the safe and stable operation of the device.
