[0001] The utility model relates to the technical field of power transformers, in particular to a power transformer with an anti-theft structure. Background Art
[0002] A power transformer is a static electrical device that is used to convert an AC voltage (current) of a certain value into another or several different voltages (currents) of the same frequency.
[0003] In the prior art, power transformers, as core equipment for energy transmission and distribution, play an important role. When alternating current is passed through the iron core of the transformer, alternating magnetic flux is generated in the iron core. These magnetic fluxes pass through the coil of the transformer and, according to the law of electromagnetic induction, generate induced electromotive force, thereby generating AC voltage in the secondary coil.
[0004] However, traditional power transformers are not equipped with anti-theft devices. Due to their large size and importance, they often become the target of theft by criminals, causing serious troubles to the operation and safety of the power system. Utility Model Content

[0010] Preferably, the sliders are provided in multiple groups, and the multiple groups of sliders are symmetrically distributed on the arc surface of the insertion rod, and the sliding grooves are provided in multiple groups, and the multiple groups of sliding grooves are symmetrically distributed on the arc surface of the insertion hole, and the sliders correspond to the sliding grooves, and the sliders are clamped in the sliding grooves, and the two are movably connected.
[0011] Preferably, there are multiple groups of limit grooves, which are circumferentially distributed on the arc surface of the screw, and there are multiple groups of limit blocks, which are circumferentially distributed on the inner wall surface of the nut, and the limit blocks correspond to the limit grooves, and the limit blocks are clamped in the limit grooves, and the two are movably connected.
[0012] Preferably, the connecting blocks are provided in multiple groups, which are circumferentially distributed in the first receiving groove, and multiple groups of notches are provided, which are circumferentially distributed on the arc surface of the insertion rod, and the connecting blocks correspond to the notches, and the connecting blocks are clamped in the notches, and the two are movably connected.

Since the limit block is stuck in the limit groove, when the nut is rotated, the screw rotates at the same time, and the two cannot be separated, thereby realizing the anti-theft function of the power transformer main body. When the nut needs to be opened, the insertion rod is stuck in the insertion hole, and the first spring will push the pulley to move through the connecting block. The thickness of the pulley is less than the thickness of the limit block, so the pulley pushes the limit block to be stored in the second storage groove. At this time, the limit between the screw and the nut disappears, and the nut can be removed. At the same time, the insertion rod is a special exclusive device that cannot be found on the market, thereby improving the anti-theft function of the transformer main body. This structure is simple and easy to operate, thereby realizing the anti-theft function of the power transformer main body, which is beneficial to improving its use effect.

[0028] Embodiment 1:
[0029] A plug hole 8 is provided on the top surface of the screw 5, a limiting groove 9 is provided on the arc surface of the screw 5, a nut 6 is sleeved on the arc surface of the screw 5, a second receiving groove 16 is provided on the arc surface of the inner wall of the nut 6, and a limiting block 19 is provided on the end surface of the second receiving groove 16. Since the limiting block 19 is stuck in the limiting groove 9, when the nut 6 is rotated, the screw 5 rotates at the same time, and the two cannot be separated, that is, the transformer main body 1 and the top cover 3 cannot be separated, thereby realizing the anti-theft of the power transformer main body 1;
[0030] A first receiving groove 10 is provided on the arc surface of the insertion rod 2, and a first spring 11 is provided inside the first receiving groove 10. Due to the elasticity of the first spring 11, the first spring 11 will push the pulley 14 to move through the connecting block 13, and the thickness of the pulley 14 is less than the thickness of the limit block 19, so the pulley 14 pushes the limit block 19 to be received in the second receiving groove 16. At this time, the limit between the screw 5 and the nut 6 disappears, and the nut 6 can be removed. A notch 15 is provided on the port surface of the first receiving groove 10, and a connecting block 13 is provided on the port surface of the first receiving groove 10.
[0031] Embodiment 2:
[0032] On the basis of the first embodiment, in order to realize the anti-theft of the power transformer body 1, the screw 5 is arranged on the surface of the top cover 3, the transformer body 1 is arranged on the lower surface of the top cover 3, the slider 4 is fixed on the arc surface of the plug rod 2, the second baffle 18 is fixed on the surface of the limit block 19, the first baffle 12 is fixed on one end surface of the connecting block 13, and the pulley 14 is arranged on the other end surface of the first baffle 12, and the sliding groove 7 is opened on the inner wall of the socket 8 to play a positioning role for the movement of the plug rod 2 in the socket 8;
[0033] There are multiple groups of sliders 4, which are symmetrically distributed on the arc surface of the insertion rod 2. There are multiple groups of sliding grooves 7, which are symmetrically distributed on the arc surface of the insertion hole 8. The sliders 4 correspond to the sliding grooves 7. The sliders 4 are clamped in the sliding grooves 7 to position the insertion rod 2 in the insertion hole 8. The two are movably connected.
[0034] There are multiple groups of limit grooves 9, which are circumferentially distributed on the arc surface of the screw 5. There are multiple groups of limit blocks 19, which are circumferentially distributed on the inner wall surface of the nut 6. The limit blocks 19 correspond to the limit grooves 9. The limit blocks 19 are stuck in the limit grooves 9, and the two are movably connected. Since the limit blocks 19 are stuck in the limit grooves 9, when the nut 6 is rotated, the screw 5 rotates at the same time, and the two cannot be separated, that is, the transformer theme 1 and the top cover 3 cannot be separated, thereby realizing the anti-theft of the power transformer body 1;
[0035] There are multiple groups of connection blocks 13, which are circumferentially distributed in the first receiving groove 10, and there are multiple groups of notches 15, which are circumferentially distributed on the arc surface of the insertion rod 2, and the connection blocks 13 correspond to the notches 15, and the connection blocks 13 are clamped in the notches 15, and the two are movably connected;
[0036] The size of the first baffle 12 is the same as that of the first receiving groove 10, the size of the connecting block 13 is the same as that of the slot 15, and the size of the first baffle 12 is larger than that of the connecting block 13, and the first baffle 12 is stuck in the first receiving groove 10, so the connecting block 13 will not fall out of the first receiving groove 10.
[0037] In actual use, the screw rod 5 is inserted into the hole between the transformer body 1 and the top cover 3, and the limit block 19 is pressed to store it in the second storage groove 16, and then the nut 6 is clamped in the screw rod 5 and the nut 6 is rotated. When the limit block 19 is clamped into the limit groove 9, the rotation of the nut 6 is stopped. At this time, the transformer body 1 and the top cover 3 are connected and fixed with the cooperation of the screw rod 5 and the nut 6. Since the limit block 19 is clamped in the limit groove 9, when the nut 6 is rotated, the screw 5 rotates at the same time, and the two cannot be separated, that is, the transformer body 1 and the top cover 3 cannot be separated, thereby realizing the anti-theft of the power transformer body 1, and when the nut 6 needs to be opened, the insertion rod 2 is clamped In the socket 8, the insertion rod 2 is then pressed to move. When the insertion rod 2 moves to the bottom of the socket 8, due to the elasticity of the first spring 11, the first spring 11 will push the pulley 14 to move through the connecting block 13, and the thickness of the pulley 14 is less than the thickness of the limit block 19, so the pulley 14 pushes the limit block 19 to be stored in the second storage groove 16. At this time, the limit between the screw 5 and the nut 6 disappears, and the nut 6 can be removed. At the same time, the insertion rod 2 is a special exclusive device that cannot be found on the market, which improves the anti-theft function of the transformer main body 1. This structure is simple and easy to operate, realizes the anti-theft function of the power transformer main body 1, and is beneficial to improving its use effect.
