[0002] A micro transformer refers to a transformer with a small volume. Compared with a conventional transformer, it has the advantages of high power density, high efficiency, low leakage inductance, good heat dissipation, and low cost. According to different classification standards, micro transformers can be divided into different types. According to the winding type, micro transformers can be divided into traditional transformers and micro transformers. The former is wound with enameled wire or multi-strand twisted wire, while the latter is composed of stacked copper foil, printed copper wire on a printed circuit board, or copper wire directly deposited on a magnetic film. According to the core material, micro transformers can be divided into ferrite transformers and amorphous transformers. The traditional assembly of micro transformers usually uses screws and other fixing materials to fix the various parts of the transformer, and connects the coils according to the designed number of turns. This method has certain disadvantages. Before assembling the micro transformer, the staff needs to carry a large number of tools, which is troublesome, and the time required for assembling it with fixing materials such as screws is long, and the efficiency is too low. Therefore, the utility model is dedicated to a new type of micro transformer that is easy to assemble. Utility Model Content

[0025] A rectangular plate 4 is fixedly mounted on both sides of the bottom plate 1, a vertical plate 5 is fixedly mounted on the top of the rectangular plate 4, a circular hole 6 is opened on the surface of the vertical plate 5, and a guide shaft 8 is movably mounted inside the circular hole 6;

[0026] A guide groove 7, which is provided at both ends of the U-shaped plate 2;

[0027] When in use, the micro transformer 3 is placed on the surface of the U-shaped plate 2, and then the staff presses the micro transformer 3. The downward pressure of the U-shaped plate 2 squeezes the spring 14, and the movable column 23 continues to go deeper into the limit groove 21. After the micro transformer 3 is pressed down to a certain distance, the guide groove 7 and the circular hole 6 are in the same horizontal plane. The staff inserts the guide shaft 8 from the inside of the circular hole 6 and extends it to the inside of the guide groove 7 to fix the U-shaped plate 2, completing the quick assembly. When disassembly is required, the guide shaft 8 is taken out, and the pressure on the spring 14 forms a reaction force to reset the U-shaped plate 2, and then the staff takes down the micro transformer 3;

[0028] The staff puts the micro transformer 3 into the surface of the U-shaped plate 2 and presses the U-shaped plate 2 down to a certain distance, then fixes the circular hole 6 and the guide groove 7 with the guide shaft 8 to complete the quick installation. Compared with the traditional device, this device can greatly shorten the installation time of the micro transformer 3, thereby improving work efficiency, reducing downtime, and thus speeding up the progress of the entire project. In addition, because fewer installers are required and the work speed is faster, the labor cost and time cost can be reduced.

[0029] Wherein, L-shaped movable brackets 9 are movably installed on both sides of the U-shaped plate 2, a threaded rod 10 is movably installed on one end surface of the L-shaped movable bracket 9, and a circular plate 12 is fixedly installed on the bottom of the threaded rod 10;

[0030] A rotating handle 11, which is fixedly mounted on the top of the threaded rod 10;

[0031] After the micro transformer 3 is placed on the surface of the U-shaped plate 2, the staff uses the L-shaped movable bracket 9 and moves the L-shaped movable bracket 9 to the top of the micro transformer 3. At this time, the staff grasps the rotating handle 11 and rotates the rotating handle 11, so that the threaded rod 10 rotates inside the L-shaped movable bracket 9 and continuously moves downward so that the circular plate 12 finally clings to the top of the micro transformer 3, and the micro transformer 3 is limited and fixed by the circular plate 12;

[0032] The staff moves the L-shaped movable bracket 9 to the top of the micro-transformer 3 and then rotates the rotating handle 11, so that the circular plate 12 at the bottom of the threaded rod 10 gradually moves toward the top of the micro-transformer 3 and finally clings to the top of the micro-transformer 3 and limits and fixes it. Compared with the traditional device, the use of this device can prevent the micro-transformer 3 from being damaged due to the force generated by shaking or vibration during daily operation, and can effectively maintain the stability and safety of the equipment.

[0033] Among them, springs 22 are arranged between the limiting grooves 21 and the movable columns 23. There are four springs 22, and the four springs 22 are evenly distributed between the four groups of limiting grooves 21 and the movable columns 23.

[0034] A second spring 22 is provided between the four groups of limit grooves 21 and the movable column 23. The cooperation between the four groups of limit grooves 21 and the movable column 23 and the second spring 22 can improve the fixing effect and the efficiency of disassembling the micro transformer 3, thereby saving time.

[0035] Among them, the bottom of the base plate 1 is fixedly installed with a support leg 19, the number of the support legs 19 is four and evenly distributed at the bottom of the base plate 1, and the bottom of the support leg 19 is fixedly installed with a support pad 20;

[0036] Four legs 19 are evenly and fixedly installed at the bottom of the base plate 1. When the four legs 19 are used, the device can provide effective support during operation. A support pad 20 is fixedly installed at the bottom of the legs 19. The support pad 20 disperses the pressure from above to achieve a better support effect.

[0037] Among them, the two sides of the rectangular plate 4 are fixedly installed with a fixing plate 15, the surface of the fixing plate 15 is provided with a circular groove 18, the side of the bottom plate 1 is provided with a second guide groove 17, and bolts 16 are arranged inside the circular groove 18 and the second guide groove 17;

[0038] A fixing plate 15 is fixedly installed on both sides of the rectangular plate 4, a circular groove 18 is opened on the surface of the fixing plate 15, and a second guide groove 17 is opened on the side of the bottom plate 1. Bolts 16 are movably installed inside the circular groove 18 and the second guide groove 17 to ensure the connection between the rectangular plate 4 and the bottom plate 1, making it more secure.

[0039] There are three groups of springs 14, and the three groups of springs 14 are evenly distributed between the bottom plate 1 and the U-shaped plate 2, and the bottom plate 1 and the U-shaped plate 2 are both made of stainless steel;

The micro transformer 3 can be quickly disassembled by the reaction force of the three groups of springs 14 to ensure the speed and efficiency of disassembly. The bottom plate 1 and the U-shaped plate 2 are made of stainless steel, which has excellent rust resistance, so as to prevent the bottom plate 1 and the U-shaped plate 2 from rusting and thus affecting the effect.

[0041] Among them, a protective block 13 is fixedly installed at the bottom of the circular plate 12, and the protective block 13 is made of rubber. The corners of the bottom plate 1 and the U-shaped plate 2 are both in arc shape;

[0042] A protective block 13 is fixedly installed at the bottom of the circular plate 12 and is made of rubber. Rubber has a good friction coefficient and can provide a good anti-slip effect to prevent the micro-transformer 3 from sliding during the clamping process, thereby ensuring the stability and accuracy of the clamping. The corners of the bottom plate 1 and the micro-transformer 3 are both arc-shaped, which makes it look more beautiful visually.

[0043] The working principle and use process of this utility model:

[0044] When in use, the micro-transformer 3 is placed on the surface of the U-shaped plate 2, and then the staff presses the micro-transformer 3. The downward pressure of the U-shaped plate 2 squeezes the spring 14, and the movable column 23 continues to penetrate into the inside of the limit groove 21. After the micro-transformer 3 is pressed down to a certain distance, the guide groove 7 and the circular hole 6 are in the same horizontal plane. The staff inserts the guide shaft 8 from the inside of the circular hole 6 and extends it to the inside of the guide groove 7 to fix the U-shaped plate 2, completing the quick assembly. When disassembly is required, the guide shaft 8 is taken out, and the pressure on the spring 14 forms a reaction force to reset the U-shaped plate 2, and then the staff removes the micro-transformer 3.

[0045] After the micro-transformer 3 is placed on the surface of the U-shaped plate 2, the staff uses the L-shaped movable bracket 9 and moves the L-shaped movable bracket 9 to the top of the micro-transformer 3. At this time, the staff grasps the rotating handle 11 and rotates the rotating handle 11, so that the threaded rod 10 rotates inside the L-shaped movable bracket 9 and continuously moves downward so that the circular plate 12 finally clings to the top of the micro-transformer 3, and the micro-transformer 3 is limited and fixed by the circular plate 12.
