Description

Technical Field

[0001] This utility model relates to the field of high-frequency transformer protection technology, specifically a high-frequency transformer with a safety protection structure. Background Technology

[0002] High-frequency transformers are power transformers that operate at frequencies exceeding intermediate frequencies. They are mainly used in high-frequency switching power supplies as high-frequency switching power supply transformers, and are also used in high-frequency inverter power supplies and high-frequency inverter welding machines as high-frequency inverter power supply transformers. High-frequency transformers generate a large amount of heat during use.

[0003] A search revealed that Chinese Patent Publication (Announcement) No. CN210984459U discloses a high-frequency transformer with high protection performance. Its general description includes a high-frequency transformer body, a protective shell covering the surface of the transformer body, and a water storage box fixedly connected to the top of the inner cavity of the protective shell. During use, the protective shell, water storage box, heat-conducting plate, heat-conducting rod, vent, first filter, air inlet pipe, fan, and second filter improve the heat dissipation performance of the high-frequency transformer. The protective plate, buffer box, first spring, pressure block, pressure rod, second spring, and limiting wheel provide a buffering function for the high-frequency transformer. This invention improves the overall protection performance of high-frequency transformers and solves the problem of poor protection performance in existing high-frequency transformers. This high-frequency transformer has the advantage of good protection performance and is worth promoting. However, the above-mentioned device still has some shortcomings. For example, although the first and second filters in the above device can block dust, dust will adhere to the filters after a period of use. If there is a lot of dust, it will clog the filters, thereby affecting the airflow inside the protective shell and reducing the heat dissipation effect. The above-mentioned device is not convenient to disassemble and replace the filters during maintenance, and cleaning the filters is cumbersome and time-consuming. Therefore, we propose a high-frequency transformer with a safety protection structure. Summary of the Invention

Example

[0015] Please see Figures 1-5 A high-frequency transformer with a safety protection structure includes: High-frequency transformer body 1; Protective mesh cover 2 is fitted onto the surface of the high-frequency transformer body 1, and a fixing cover 3 is fixedly connected to the protective mesh cover 2. The heat dissipation mechanism is mounted on the fixed cover 3 and includes two openings, both of which are located on the fixed cover 3. A duct 4 is fixedly connected to each opening, and a fixed plate 5 is fixedly connected to each duct 4. Two fans 6 are installed between the fixed plate 5 and the duct 4. Four positioning ports are provided on the duct 4, and a filter screen 7 is placed inside the duct 4. Four positioning blocks 8 are fixedly connected to the filter screen 7, located within the positioning ports. Limiting rings 9 are fixedly connected to the positioning blocks 8. A fixed pipe 10 is fixedly connected between the duct 4 and the fixed cover 3. Two limiting blocks 11 are slidably connected inside the fixed pipe 10, with one end of each limiting block 11 located within the limiting ring 9. A control mechanism is provided on the fixed pipe 10 and the two limiting blocks 11. The fans 6 are used for heat dissipation, the positioning blocks 8 and the positioning ports are used for positioning, and the limiting blocks 11 and the limiting rings 9 are used to limit and fix the filter screen 7 for easy replacement and cleaning.

[0016] The control mechanism includes two fixed blocks 12 and two pull ropes 13. The two fixed blocks 12 are fixedly connected inside the fixed tube 10, and the two pull ropes 13 are fixedly connected to the two limit blocks 11 respectively. A spring 14 is provided between the fixed blocks 12 and the limit blocks 11. An opening 1 is provided on the fixed block 12. The pull ropes 13 are located inside the spring 14 and the opening 1. Both pull ropes 13 pass through the fixed tube 10 through the opening 2. A pull plate 15 is fixedly connected to one end of the two pull ropes 13. The pull blocks and pull ropes 13 are used to facilitate the control of moving the limit blocks 11. The spring 14 is used to push the limit blocks 11 into the limit ring 9 to achieve fixed limiting.

[0017] A pull ring 16 is fixedly connected to the pull plate 15 to facilitate the movement of the pull plate 15 and the pull rope 13.

[0018] Multiple connecting blocks 17 are fixedly connected between the protective net cover 2 and the fixed cover 3, and two connecting blocks 18 are fixedly connected between the protective net cover 2 and the fixed plate 5, which are used to improve the firmness between the protective net cover 2 and the fixed cover 3.

[0019] Two air guide blocks 19 are fixedly connected inside the fixed cover 3 to guide the airflow, improve the heat dissipation effect and promote air circulation.

[0020] Four mounting blocks 20 are fixedly connected to the fixed cover 3. The mounting blocks 20 have mounting holes for easy fixing of the fixed cover 3.

[0021] It should be further explained that the fan 6 in this embodiment is a conventional device known to those skilled in the art and available on the market. The model can be selected or customized according to actual needs. In this patent, we only use it and have not improved its structure and function. Its setting method, installation method and electrical connection method can be debugged and operated by those skilled in the art according to the requirements of its instruction manual. It will not be described in detail here. The fan 6 is equipped with a matching control switch. The installation position of the control switch can be selected according to the actual use needs to facilitate the operator's operation and control.

[0022] In summary, the working principle and process of this high-frequency transformer with safety protection structure are as follows: First, place the high-frequency transformer with safety protection structure at the required location. Then, when heat dissipation is needed, start the four fans 6. Two fans 6 on one side blow air into the fixed cover 3, while the two fans 6 on the other side exhaust the air from the fixed cover 3. This facilitates better ventilation and heat dissipation for the high-frequency transformer body 1 inside the fixed cover 3 and the protective mesh cover 2. The filter screen 7 blocks dust in the air. When it is necessary to replace the filter screen 7 for maintenance, pull the pull ring 16. The pull ring 16 moves the pull plate 15 and the pull rope 13. The pull rope 13 pulls the limit block 11 to move out of the limit ring 9. At this time, the spring 14 will be squeezed. Then, the filter screen 7 can be taken out through the positioning block 8 for replacement or cleaning. The operation is simple and quick, improving practicality.

[0023] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
