Description

Technical Field

[0001] The utility model belongs to the technical field of high-frequency transformers, in particular to a safety structure of a high-frequency transformer. Background Art

[0002] A high-frequency transformer is a power transformer with an operating frequency exceeding the medium frequency (10kHz). It is mainly used as a high-frequency switching power supply transformer in a high-frequency switching power supply. It is also used as a high-frequency inverter power supply transformer in a high-frequency inverter power supply and a high-frequency inverter welding machine. According to the operating frequency, it can be divided into several grades: 10kHz-50kHz, 50kHz-100kHz, 100kHz~500kHz, 500kHz~1MHz, and above 10MHz.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model provides a rebound mechanism. When the high-frequency transformer senses vibrations from the left and right, the support plate moves away from the impacted position and slides on the outer wall of the support rod. When the support plate moves to one side, the support plate squeezes the third spring. The third spring also squeezes the push plate while squeezing.

[0016] 2. The utility model sets a fixing mechanism. When the high-frequency transformer is placed on the top of the support plate, the cylinder at the bottom of the transformer is placed in the circular groove at the top of the support plate. When the cylinder is squeezed downward, the cylinder pushes the inclined groove at the rear end of the blocking rod forward. When the cylinder squeezes the blocking rod to the front end, the cylinder falls to the bottom of the circular groove, and the blocking rod is rebounded by the fifth spring to the inside of the first circular hole opened on the surface of the cylinder, so that the cylinder is fixed, thereby fixing the transformer. When the transformer is to be taken out, the second handle is pulled out to pull out the second baffle plate, the second baffle plate brings out the blocking rod, and the blocking rod squeezes the fifth spring. When the right side of the blocking rod is in the second circular hole, the transformer is taken out. When the second handle is released, the fifth spring pushes the blocking rod to reset, thereby improving the practicability of the device.
