[0013] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0014] Example 1:

[0015] The oil-immersed power transformer anti-theft device proposed in this embodiment includes two components: a locking assembly and a locking assembly. The locking assembly has a predetermined bending arc and operating size, and is provided with a through hole of the predetermined operating size. The locking assembly passes through the through hole provided in the locking assembly and is movably connected to the locking assembly, having a predetermined operating size and supporting force. The locking assembly is a shell with a predetermined bending arc, and the shell is provided with a recessed locking groove of the predetermined operating size, and the through holes are located at the upper and lower ends of the recessed locking groove in the operating direction. In the later operation process, the locking assembly can be inserted into the recessed locking groove provided in the shell, and then the locking assembly can be locked and limited accordingly by screwing, thereby achieving the corresponding anti-theft function.

[0016] Example 2:

[0017] Based on the first embodiment, the locking assembly includes a bolt 4 and a plug 2. The bolt 4 has a predetermined operating size and supporting force, and its operating size is compatible with the operating size of the through hole of the housing 3. The plug 2 is connected to the bolt 4 and has a predetermined operating size, and its overall operating size is compatible with the through hole of the housing 3. A loose block 5 is provided at one end of the bolt 4, and a cover plate is provided at the end near the plug 2. Both the loose block 5 and the cover plate can be adjusted to the corresponding operating position in response to the movement of the bolt 4. The housing 3 has a corresponding locking groove, and the plug 2 has a corresponding locking extension. The operating size of the locking extension of the plug 2 is compatible with the operating size of the locking groove of the housing 3. In a further preferred embodiment, the locking groove of the housing 3 is a staggered cross-shaped slot. During later operation, the locking extension of the plug 2 can be aligned with the cross-shaped slot of the housing 3, and then locked by screwing, thereby achieving the corresponding anti-theft purpose.

[0018] Based on the above embodiment, the working process of the present invention is as follows: first, the transformer box cover and the box edge are connected and fixed together with nuts and screws, and then the recessed positioning groove of the shell 3 is pushed into the box cover and the box edge to wrap the box cover and the box edge, and then the bolt 4 is inserted into the through hole of the shell 3. At this time, the end of the bolt 4 with the movable block 5 is facing downward, and the end with the plug 2 is facing upward, and the positioning extension end is aligned with the positioning groove of the shell 3, and then the bolt 4 is pressed downward until the movable block 5 is inserted into the through hole of the shell 3. At this time, the plug 2 is just placed in the positioning position of the positioning groove, and the pressure cover 1 is screwed to drive the bolt 4, the plug 2 and the movable block 5 to rotate synchronously, thereby realizing the corresponding locking function to complete the anti-theft operation.

[0019] In a further preferred embodiment, the working surface of the gland 1 may be provided with a specific anti-theft locking groove, which requires a special screwing tool to rotate the gland 1 and install and remove the bolt 4. The gland 1 may also be configured as a lock core structure, which requires a corresponding key to unlock, to achieve the purpose of anti-theft. This is a prior art and will not be described in detail in this application.

[0020] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes may be made to it in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims.
