Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a mounting base for a power transformer. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core. In electrical equipment and wireless circuits, it is often used to increase or decrease voltage, match impedance, and provide safety isolation. During the installation and use of the transformer, the transformer needs to be installed and fixed on a base to ensure stable use of the transformer.

[0003] During the installation of existing transformers, lifting equipment is usually used to lift the transformer and move it to the location where it needs to be installed. The transformer is then assisted in straightening by staff to achieve a stable connection between the transformer and the base, and fixed with multiple bolts. However, during the installation process, since multiple bolts are required for fixing, the transformer must be accurately docked with the base. Once the position is offset, multiple bolts cannot be fixed, and repeated adjustments need to be made by lifting equipment and manual labor. The process is relatively slow, which affects the installation efficiency of the transformer and increases the difficulty of the work. Utility Model Content

A positioning groove 30 is provided on the inner bottom wall of the limiting groove 22. A positioning column 31 is clamped in the positioning groove 30. The installation position of the transformer body 2 is quickly locked by clamping the positioning column 31 with the positioning groove 30. The two moving rods 29 are moved so that the two moving rods 29 move toward the center with their corresponding L-shaped card strips 28 at the same time, so that the L-shaped card strip 28 limits the connection block 25, and the docking column 27 docks with the docking groove 26 in the connection block 25 to achieve the preliminary fixation of the transformer body 2. The moving rod 29 and the fixed plate 21 are fixed by fixing bolts 71. The moving rod 29 and the fixed plate 21 are fixed by two fixing bolts 71. The movable rod 41 is fixed to prevent the movable rod 29 from moving randomly, causing the L-shaped card strip 28 to be out of contact with the connecting block 25. The top of the positioning column 31 is fixedly connected to a movable rod 41, and the outer wall of the movable rod 41 is slidably connected to a fixed block 42. The fixed block 42 is fixedly connected to the fixed plate 21. A spring 43 is sleeved on the outer surface of the movable rod 41, and the two ends of the spring 43 are respectively fixedly connected to the positioning column 31 and the fixed block 42. The coordinated use of the movable rod 41 and the spring 43 can make the positioning column 31 squeeze the spring 43 to realize the sliding of the positioning column 31 in the limit groove 22. When the positioning column 31 moves just above the positioning groove 30, the spring 43 rebounds quickly, which can quickly lock the installation position of the transformer body 2.

In the process of docking the connecting blocks 25 with the limiting groove 22, the four rollers 52 are also docked with the corresponding slide grooves 51. Then, the staff pushes the transformer body 2. In the process of pushing, the pulling button 91 is lifted to squeeze the positioning column 31 against the spring 43, and then the movable rod 41 moves upward to slide on the limiting groove 22, and then the pulling button 91 can be released. When the positioning column 31 moves to the positioning groove 30 When it is directly above, the positioning column 31 loses its force, and the spring 43 rebounds quickly, so that the positioning groove 30 is docked with the positioning column 31, thereby locking the installation position of the transformer body 2, and then the two moving rods 29 are moved to the center position at the same time, so that the moving rod 29 drives the L-shaped clamping strip 28 and the docking column 27 to dock with the connecting block 25, thereby fixing the two connecting blocks 25, and fixing the corresponding moving rod 29 to the fixing plate 21 through two fixing bolts 71, and finally, docking with the corresponding positioning holes 61 through four positioning bolts 62, and through the use of the positioning bolts 62, the fixing plate 21 is completely fixed to the base body 1, thereby realizing the use process of the transformer mounting base.
