Description

Technical Field

[0001] The utility model relates to the field of high and low frequency transformers, in particular to a high and low frequency transformer with a protection structure. Background Art

[0002] Low-frequency transformers are used to transmit signal voltage and signal power, and can also achieve impedance matching between circuits. They have an isolation effect on direct current. There is no difference in principle between high-frequency transformers and low-frequency transformers, but due to the different frequencies of high and low frequencies, the iron cores used in the transformers are different. Low-frequency transformers generally use high-permeability silicon steel sheets, while high-frequency transformers use high-frequency ferrite cores. Existing high- and low-frequency transformers lack protective structures when in use, and are easily damaged by collisions, which affects their service life and has certain adverse effects on people's use. For this reason, we propose a high- and low-frequency transformer with a protective structure. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] This embodiment is a high-low frequency transformer with a protection structure.

[0022] like Figure 1-4 As shown, it includes a base 1, a transformer body 2 is arranged in the middle of the upper outer surface of the base 1, a protective mechanism 3 is arranged on one side of the transformer body 2, and the protective mechanism 3 includes a fixed cover 4, a protective plate 5, an elastic pad 6, a first magnetic block plate 7, a hanging ring 8, an ear plate 9, a hole groove 10, a guide groove 11, a spring 12, a fixed block 13, a limiting block 14, a limiting groove 15, a fixed frame 16 and a guide block 17, two groups of fixed frames 16 are respectively fixedly installed on both sides of the upper outer surface of the base 1, the limiting groove 15 is opened on one side of the outer surface of the fixed frame 16, the fixed cover 4 is located at the upper end of the base 1, the two groups of ear plates 9 are respectively fixedly installed on the upper end of the middle of the outer surfaces of both sides of the fixed cover 4, and the hanging ring 8 is fixedly installed on the upper outer surface of the ear plate 9.

[0023] Four groups of protective plates 5 are respectively located around the fixed cover 4, the elastic pad 6 is located on the outer surface of one side of the protective plate 5, the fixed block 13 is fixedly installed on the outer surface of the other side of the protective plate 5, the guide groove 11 is opened on the outer surface of one side of the fixed block 13, the spring 12 is located inside the guide groove 11, the guide block 17 is located on the outer surface of one side of the spring 12, the first magnetic block plate 7 is located on the outer surface of one side of the guide block 17, eight groups of hole grooves 10 are respectively opened at the upper and lower ends of the outer surface around the fixed cover 4, and two groups of limit blocks 14 are respectively fixedly installed at the lower ends of the middle of the inner surface on both sides of the fixed cover 4; the limit block 14 and the limit groove 15 are slidably connected; the fixed block 13 and the hole groove 10 are slidably connected; the upper and lower ends of the outer surface around the transformer body 2 are provided with second magnetic block plates, and the first magnetic block plate 7 and the second magnetic block plate are magnetically connected.

[0024] It should be noted that the utility model is a high-low frequency transformer with a protective structure. After the upper end of the fixed cover 4 is hoisted through the lifting ring 8, the fixed cover 4 is aligned with the transformer body 2. After the fixed cover 4 is lowered along the transformer body 2, the limit block 14 slides along the limit groove 15 to push the protective plate 5, and drives the first magnetic block plate 7 set on one side of the protective plate 5 to be magnetically connected with the second magnetic block plate set on one side of the transformer body 2. The fixed cover 4 is limited. When it is impacted by the outside world, the impact force acts on the elastic pad 6 set on one side of the protective plate 5. The elastic pad 6 elastically buffers and drives the protective plate 5 to move to one side. The fixing block 13 moves sideways, driving the fixing cover 4 to slide along the fixing cover 4, so that the guide groove 11 slides along the guide block 17 to compress the spring 12 for buffering, thereby reducing the impact force to protect the transformer body 2. The fixing cover 4 can protect the transformer body 2, and can play an elastic buffering role under the mutual cooperation of the fixing cover 4, the protective plate 5, the elastic pad 6, the first magnetic block plate 7, the hole groove 10, the guide groove 11, the spring 12, the fixing block 13, and the guide block 17, thereby avoiding damage to the transformer body 2 caused by external impact, improving the service life of the transformer body 2, and facilitating the limited placement of the fixing cover 4.
