Specifically, the bottom channel steel 100 is placed on the ground, and the plurality of columns 200 are vertically arranged on the upper surface of the bottom channel steel 100.
[0027] The clamping channel steel 300 is a structure for clamping and fixing multiple iron core sheets 400. The clamping channel steel 300 is inserted between adjacent columns 200, and multiple iron core sheets 400 are arranged between the clamping channel steels 300. The connecting rod 500 is inserted between adjacent clamping channel steels 300, and the total length of the connecting rod 500 is greater than the distance between adjacent clamping channel steels 300. The connecting rod 500 passes through two adjacent clamping channel steels 300, and the connecting rod 500 is used to clamp the clamping channel steels 300 so that the iron core sheets 400 located between the clamping channel steels 300 are fixed together.
[0028] In this embodiment, both ends of the connecting rod 500 are provided with a first thread 600 and a second thread 700, wherein the first thread 600 is located beside the second thread 700, and the first thread 600 and the second thread 700 have opposite screw directions. The locking member includes a first bolt 800 and a second bolt 900, wherein the first bolt 800 is connected to the connecting rod 500 through the first thread 600, and the second bolt 900 is connected to the connecting rod 500 through the second thread 700. When the first bolt 800 and the second bolt 900 are connected to the connecting rod 500, the first bolt 800 and the second bolt 900 are in contact.
[0029] In the transformer core structure provided in the embodiment of the present application, a plurality of iron core sheets 400 can be clamped by using a clamping channel steel 300, and the clamping channel steel 300 is fixed by a connecting rod 500. Both ends of the connecting rod 500 are provided with a first thread 600 and a second thread 700 with opposite thread directions, and the first bolt 800 included in the locking member is connected to the first thread 600, and the second bolt 900 is connected to the second thread 700, and the first bolt 800 and the second bolt 900 are in contact. In this way, when the transformer vibrates, the first bolt 800 and the second bolt 900 will fit tightly together to prevent loosening. The above structural design can solve the problem of loosening of the bolts on the transformer clamp.
[0030] In some embodiments, preferably, the second thread 700 can be located on a side close to the clamping channel steel 300 , and the thickness of the second bolt 900 is equal to the length of the second thread 700 , so as to prevent the first bolt 800 from accidentally touching the second thread 700 .
[0031] In some embodiments, a plurality of stoppers 910 are disposed on the contacting surfaces of the first bolt 800 and the second bolt 900, and the plurality of stoppers 910 are distributed along the circumferential direction on the contacting surfaces of the first bolt 800 and the second bolt 900. When the first bolt 800 and the second bolt 900 are in contact, they can abut against each other through the stoppers 910.

The clamping pin 510 is penetrated on the connecting rod 500 along the radial direction of the connecting rod 500. The clamping pin 510 can prevent the first bolt 800 and the second bolt 900 from detaching from the connecting rod 500 due to vibration or other reasons.
