Description

Technical Field

[0001] This utility model relates to the field of high-frequency transformer technology, and in particular to a fastening and heat dissipation structure for a high-frequency transformer. Background Technology

[0002] In the field of electronic power, high-frequency transformers play an irreplaceable role as a key electrical component. They are widely used in many electronic products such as switching power supplies, inverters, and communication equipment, mainly undertaking important functions such as voltage transformation, electrical isolation, and energy transmission.

[0003] Most of the fastening structures commonly used in the market for high-frequency transformers adopt a fixed design. Their installation dimensions and specifications are predetermined, lacking flexibility and adjustability. This type of fixed fastening structure cannot be adjusted according to the actual width of the high-frequency transformer, resulting in poor adaptability for installation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a robust heat dissipation structure for high-frequency transformers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fastening and heat dissipation structure for a high-frequency transformer includes a mounting plate. The upper end of the mounting plate has a mounting groove. A bidirectional threaded rod is provided inside the mounting groove. One end of the bidirectional threaded rod is rotatably connected to the inner wall of the mounting groove, and the other end of the bidirectional threaded rod is fixedly connected to a rotating rod. The end of the rotating rod away from the bidirectional threaded rod passes through the inner wall of the mounting groove and extends to the outer side of the mounting plate. Two sliders are threaded onto the bidirectional threaded rod. The sliders are slidably disposed inside the mounting groove. A connecting mechanism is provided at the upper end of each slider, and a heat dissipation mechanism is provided on the connecting mechanism. Mounting holes are provided at the four corners of the upper end of the mounting plate.

[0007] As a further improvement of this utility model, a locking nut is threaded onto the side wall of the rotating rod, and the locking nut abuts against the side wall of the mounting plate.

[0008] As a further improvement of this utility model, the connecting mechanism includes a connecting frame fixedly connected to the upper end of the slider, a connecting groove is provided on the side wall of the connecting frame, and two connecting bolts are provided inside the connecting groove.

[0009] As a further improvement of this utility model, the heat dissipation mechanism includes a mounting frame located above the connecting bracket, and a heat dissipation fan is installed inside the mounting frame.

[0010] As a further improvement of this utility model, a grille is fixedly connected to one side of the mounting frame, and a dustproof net is fixedly connected to the other side of the mounting frame.

[0011] As a further improvement of this utility model, the upper end of the connecting frame is fixedly connected to two fixing blocks, which are located on both sides of the mounting frame. A pin is horizontally inserted through the mounting frame and is rotatably connected to the mounting frame. The two ends of the pin pass through the two fixing blocks and are fixedly connected to them. A locking bolt is threaded through the side wall of the fixing block and screwed into it. The side wall of the mounting frame is provided with a locking hole that mates with the locking bolt.

[0012] The beneficial effects of this utility model are:

[0013] By driving the bidirectional threaded rod to rotate, the two sliders can move synchronously due to the screw connection between the slider and the bidirectional threaded rod, thereby driving the connecting frame to move and adjusting the distance between the two connecting frames. This allows for the installation of high-frequency transformers of different widths, making it more adaptable and meeting diverse application needs.

[0014] The mounting frame and its internal cooling fan, dust filter, and grille can be rotated around the pivot to a horizontal position. When installing a high-frequency transformer, this reduces the risk of bumping or scratching the transformer or its connecting wires that might occur when the mounting frame is in a vertical position. This significantly improves operational safety and maintenance convenience, making the installation process more convenient and safer. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-4 A fastening and heat dissipation structure for a high-frequency transformer includes a mounting plate 1. The upper end of the mounting plate 1 has a mounting groove 3, and mounting holes 2 are provided at each of the four corners of the upper end of the mounting plate 1. The mounting plate 1 can be installed using existing screws passing through the mounting holes 2. The mounting groove 3 contains a bidirectional threaded rod 14 with opposite thread directions on both sides. One end of the bidirectional threaded rod 14 is rotatably connected to the inner wall of the mounting groove 3, and the other end of the bidirectional threaded rod 14 is fixedly connected to a rotating rod 15. A locking nut 16 is threaded onto the side wall of the rotating rod 15. The locking nut 16 is connected to the mounting... The side walls of plate 1 abut against each other. The end of the rotating rod 15 away from the bidirectional threaded rod 14 passes through the inner wall of the mounting groove 3 and extends to the outer side of the mounting plate 1. Two sliders 19 are threadedly sleeved on the bidirectional threaded rod 14. The sliders 19 are slidably disposed inside the mounting groove 3. The upper ends of the two sliders 19 are provided with connecting mechanisms. By driving the bidirectional threaded rod 14 to rotate, since the sliders 19 are screwed to the bidirectional threaded rod 14, the two sliders 19 can move synchronously, thereby driving the connecting frame 4 to move and adjusting the distance between the two connecting frames 4 to meet the installation of high-frequency transformers 5 of different widths, thus having higher adaptability.

[0022] The connecting mechanism is equipped with a heat dissipation mechanism, which includes a mounting frame 6 located above the connecting frame 4. A cooling fan 11 is installed inside the mounting frame 6. A grille 12 is fixedly connected to one side of the mounting frame 6, and a dustproof net 7 is fixedly connected to the other side of the mounting frame 6. The cooling fan 11 can dissipate heat from the high-frequency transformer 5, and the dustproof net 7 can filter the air drawn in by the cooling fan 11.

[0023] The connecting mechanism includes a connecting frame 4 fixedly connected to the upper end of the slider 19. The side wall of the connecting frame 4 is provided with a connecting groove 17. The connecting groove 17 is provided with two connecting bolts 18. The high-frequency transformer 5 is connected to the connecting frame 4 through the connecting bolts 18, so that the high-frequency transformer 5 can be connected and installed, and the high-frequency transformer 5 can be conveniently installed.

[0024] Two fixing blocks 8 are fixedly connected to the upper end of the connecting frame 4. The two fixing blocks 8 are located on both sides of the mounting frame 6. A pin 9 is horizontally inserted through the mounting frame 6. The pin 9 is rotatably connected to the mounting frame 6. The two ends of the pin 9 pass through the two fixing blocks 8 respectively and are fixedly connected to the fixing blocks 8. A locking bolt 10 is inserted through the side wall of the fixing block 8 and screwed into the fixing block 8. A locking hole 13 is provided on the side wall of the mounting frame 6 to cooperate with the locking bolt 10. By inserting the locking bolt 10 into the locking hole 13, the mounting frame 6 can be fixed. When the locking bolt 10 is loosened, the fixing of the mounting frame 6 can be released. The mounting frame 6 can rotate around the pin 9. When installing the high-frequency transformer 5, the mounting frame 6 can be rotated to a horizontal state to facilitate the installation of the high-frequency transformer 5. At the same time, it is not easy for the high-frequency transformer 5 to hit the mounting frame 6 during installation, so as to avoid damage. When the high-frequency transformer 5 is in use, the mounting frame 6 can be rotated to a vertical state to facilitate the heat dissipation of the high-frequency transformer 5.

[0025] In use, this invention is first adjusted according to the width of the high-frequency transformer 5 to be installed. The operator rotates the rotating rod 15 extending to the outside of the mounting plate 1, causing the bidirectional threaded rod 14 fixed thereto to rotate within the mounting groove 3. Since the threads on both sides of the bidirectional threaded rod 14 are opposite in direction, the two sliders 19 threaded onto it slide synchronously towards or away from each other within the mounting groove 3. This causes the two connecting frames 4 fixed to the upper end of the sliders 19 to move closer or further apart, thus adjusting the spacing of the connecting frames 4 to accommodate high-frequency transformers 5 of different widths. After adjustment, the threaded sleeves on the rotating rod are tightened. Tighten the locking nut 16 on 15 to abut against the side wall of the mounting plate 1, thereby locking the position of the bidirectional threaded rod 14 and ensuring the stability of the slider 19 and the connecting bracket 4. Then, install the high-frequency transformer 5. At this time, first loosen the locking bolt 10 screwed on the fixing block 8 to disengage it from the locking hole 13 on the side wall of the mounting frame 6 and release the fixing of the mounting frame 6. At this time, the mounting frame 6 can rotate around the pin 9, flipping the mounting frame 6 together with its internal cooling fan 11, the grille 12 fixed on one side and the dustproof net 7 fixed on the other side to a horizontal state, freeing up operating space and avoiding collisions during installation.

[0026] Next, place the high-frequency transformer 5 in place, and use the connecting bolt 18 to pass through the connecting groove 17 on the side wall of the connecting frame 4 to secure the high-frequency transformer 5 between the two connecting frames 4. After the high-frequency transformer 5 is securely installed, rotate the mounting frame 6 back to the vertical position around the pin 9 so that the cooling fan 11 is facing the high-frequency transformer 5. Then tighten the locking bolt 10 so that it is inserted into the locking hole 13 on the mounting frame 6 to relock the vertical position of the mounting frame 6.

[0027] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
