DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4The utility model provides the following technical solutions: a transformer silicon steel sheet, comprising a first silicon steel sheet body 1 and a second silicon steel sheet body 2, a positioning groove 3 is provided on the upper surface of the first silicon steel sheet body 1, a positioning block 4 is fixedly installed on the lower surface of the first silicon steel sheet body 1, a fixing groove 5 is provided on one side of the first silicon steel sheet body 1, a connecting block 6 is fixedly installed on one side of the second silicon steel sheet body 2, a buffer spring 7 is fixedly connected to the inner wall of the connecting block 6, a clamping block 8 is fixedly connected to one end of the buffer spring 7, a locking bolt 9 is provided on the surface of the first silicon steel sheet body 1, and a nut 10 is threadedly connected to the surface of the locking bolt 9.

[0019] Before using the silicon steel sheet, the staff inserts the connecting block 6 on one side of the second silicon steel sheet body 2 into the fixing groove 5 on one side of the first silicon steel sheet body 1. When the inclined clamping block 8 is inserted into the fixing groove 5, the clamping block 8 will touch the first silicon steel sheet body 1, and the clamping block 8 will be contracted by the buffer spring 7, so that the clamping block 8 and the connecting block 6 are inserted into the fixing groove 5. At this time, the buffer spring 7 will drive the clamping block 8 to press against the first silicon steel sheet body 1 through elastic force, fix the connecting block 6 inserted into the fixing groove 5, improve the connection strength between the first silicon steel sheet body 1 and the second silicon steel sheet body 2, and facilitate the connection and assembly between the first silicon steel sheet body 1 and the second silicon steel sheet body 2. After the silicon steel sheets are assembled, the staff can assemble different silicon steel sheets. Stacking allows the positioning block 4 to be inserted into the positioning groove 3, thereby positioning and fixing multiple silicon steel sheets to avoid misalignment between different silicon steel sheets. At the same time, after multiple silicon steel sheets are stacked, the staff can insert the locking bolt 9 into the differently stacked silicon steel sheets, and then fix the differently stacked silicon steel sheets by connecting the nut 10 with the locking bolt 9, so that multiple silicon steel sheets can be conveniently stacked and fixed, avoiding affecting the subsequent use of the transformer silicon steel sheets and improving the use effect of the silicon steel sheets. The staff can observe the specifications of the silicon steel sheets through the product specification mark 11 to determine whether the silicon steel sheets used meet the requirements. The weight-reducing holes 12 on the surface of the first silicon steel sheet body 1 are used to reduce the weight of the silicon steel sheets, which is convenient for the subsequent stacking and use of the silicon steel sheets.

[0020] In one aspect of the present embodiment, the E-shaped first silicon steel sheet body 1 is conveniently connected and assembled with the second silicon steel sheet body 2, so that the silicon steel sheet is assembled and convenient for subsequent use.

[0021] In one aspect of this embodiment, the weight-reducing holes 12 on the surface of the first silicon steel sheet body 1 are used to reduce the weight of the silicon steel sheet, making it easier for the silicon steel sheets to be stacked and used later.

[0022] In one aspect of the present embodiment, when the inclined clamping block 8 is inserted into the fixing groove 5, the clamping block 8 will touch the first silicon steel sheet body 1, and the clamping block 8 will shrink through the buffer spring 7, so that the clamping block 8 and the connecting block 6 are inserted into the fixing groove 5, thereby facilitating the connection and assembly between the first silicon steel sheet body 1 and the second silicon steel sheet body 2.

[0023] In one aspect of this embodiment, the staff can observe the specifications of the silicon steel sheet through the product specification mark 11 and determine whether the silicon steel sheet used meets the requirements.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
