[0023] The following is combined with Figures 1 to 12 The following describes embodiments of the present invention.

[0024] According to an embodiment of the present invention, a power device anti-theft structure is provided, comprising: a back hanger 1, fixedly mounted on an external component; a power device, the housing 2 of which is detachably connected to the back hanger 1; a connector 3, at least one side of the housing 2 is provided with a connector 3; one end of the connector 3 is snapped into the housing 2 and fixedly connected to the housing 2 by a fastener 4, and the other end of the connector 3 is fixedly connected to the back hanger 1 by a lock 6.

[0025] It should be noted that power equipment includes, but is not limited to, rectifiers, inverters, and converters.

[0026] In this embodiment, during installation, the back hanger 1 is fixedly mounted on an external component, and then the power device is detachably connected to the back hanger 1 via its housing 2 for fixation. At the same time, a connector 3 is provided on the side of the housing 2. One end of the connector 3 is snapped into the housing 2 and fixed with a fastener 4, while the other end of the connector 3 is locked by a lock 6. The connector 3 is limited by snapping into the housing 2 to prevent the housing 2 from moving, and the fastener 4 and lock 6 fix it in place, so that the connector 3 fits snugly with the housing 2 and the back hanger 1, which plays a dual role in preventing theft and improving the anti-theft performance. The overall structure is simple and convenient for installation and disassembly.

[0027] In one embodiment, such as Figures 1 to 3 , Figure 4 and Figure 5 As shown, the side wall of the housing 2 is provided with a vertical hole 7, and the side wall of the back hanger 1 is provided with a first transverse hole 8; the connector 3 is provided with a first pin 9 and a second pin 10; the first pin 9 is inserted into the vertical hole 7 to restrict the housing 2 from moving laterally; the second pin 10 is inserted into the first transverse hole 8 to restrict the housing 2 from moving vertically.

[0028] It should be noted that the first pin 9 and the second pin 10 have a plate-like structure.

[0029] In this embodiment, during installation, the first pin 9 of the connector 3 is inserted into the vertical hole 7 to restrict the housing 2 from moving laterally, and the second pin 10 is inserted into the first horizontal hole 8 to restrict the housing 2 from moving vertically. It is then fixed by the fastener 4 and the lock 6, so that the connector 3 fits snugly with the housing 2 and the back hanger 1, and is limited by the first pin 9 and the second pin 10. When disassembling, the fastener 4 and the lock 6 must be removed at the same time to disassemble the connector 3, thereby improving the anti-theft performance.

[0030] In one embodiment, such as Figure 4 and Figure 5 As shown, the first pin 9 has a first locking part 11 on both the upper and lower sides along the vertical direction. The length of the first pin 9 is greater than the length of the vertical hole 7. The side wall of the housing 2 can be movably locked into the first locking part 11.

[0031] In this embodiment, by providing first engaging portions 11 on both sides of the first pin 9, and by ensuring that the length of the first pin 9 is greater than the length of the vertical hole 7, during installation, the top end of the first pin 9 can be inserted into the vertical hole 7 first. The space formed by the first engaging portion 11 and the first pin 9 is then movablely engaged with the side wall of the vertical hole 7, allowing the entire assembly to move upwards. This facilitates the insertion of the bottom end of the first pin 9 into the vertical hole 7. After the entire first pin 9 is inserted into the vertical hole 7, the first pin 9 is then moved downwards by a predetermined distance, allowing the two first engaging portions 11 to engage with the upper and lower side walls of the vertical hole 7 respectively. This facilitates installation. Furthermore, after being fixed to the lock 6 by the fastener 4, the housing 2 is difficult to detach from the connector 3 under the engaging action of the first engaging portion 11, further improving the anti-theft performance.

[0032] In one embodiment, such as Figure 3 , Figure 4 and Figure 5 As shown, the back hanger 1 has a first connecting hole 12 on its side wall, and the connector 3 has a second connecting hole 13 corresponding to the first connecting hole 12. The lock 6 passes through the first connecting hole 12 and the second connecting hole 13 in sequence to fix it.

[0033] In this embodiment, by providing a first connecting hole 12 and a second connecting hole 13 on the side wall of the back hanger 1 and the connector 3 respectively, after the connector 3 is connected, the lock 6 is fixed by passing through the first connecting hole 12 and the second connecting hole 13 in sequence, which facilitates installation and disassembly.

[0034] As a possible implementation method, it can also be, for example... Figure 2 , Figure 3 as well as Figures 6 to 8As shown, the connector 3 has a mating part 14 at one end connected to the back hanger 1. The mating part 14 is bent towards the back hanger 1 to form a second snap-fit ​​part 15. The mating part 14 is adapted to snap-fit ​​onto the side wall of the back hanger 1 through the second snap-fit ​​part 15. A second connecting hole 13 is provided on the mating part 14. An installation gap is formed between the mating part 14 and the second pin 10, which is used for the side wall of the back hanger 1 to pass through. In this embodiment, by providing a mating part 14 on the connector 3, forming a second snap-fit ​​part 15 by bending the mating part 14, and providing a second connecting hole 13 on the mating part 14, and by forming an installation gap between the mating part 14 and the second pin 10, an installation space is provided so that the side wall of the back hanger 1 can pass through the installation gap and snap-fit ​​onto the second snap-fit ​​part 15. The installation space provides the freedom to complete the engagement of the first pin 9 with the vertical hole 7 and the second pin 10 with the first horizontal hole 8, avoiding jamming during installation. During installation, first, the side wall of the back hanger 1 is inserted into the installation gap. Then, the first pin 9 is inserted into the vertical hole 7, and the second pin 10 is inserted into the first horizontal hole 8. After the installation is completed, the second locking part 15 is finally locked onto the side wall of the back hanger 1 using the operating space of the installation gap. At this time, the second connecting hole 13 is aligned with the first connecting hole 12 and locked by the lock 6. By setting the second locking part 15 to lock onto the side wall of the back hanger 1, the position is further limited, improving the overall stability and anti-theft performance.

[0035] As a possible implementation method, it can also be, for example... Figures 9 to 12As shown, the housing 2 is provided with a second transverse hole 16, and the connector 3 is provided with a third pin 17 for fitting into the second transverse hole 16.

The connector 3 has a first position where the third pin 17 is aligned with the second transverse hole 16 and a second position where the third pin 17 engages with the second transverse hole 16. When the connector 3 is in the second position, one end of the connector 3 is fixedly connected to the housing 2 by a fastener 4, and the other end of the connector 3 is fixedly connected to the back hanger 1 by a locking member 6. In this embodiment, by providing a third pin 17 on the connector 3, the connector 3 is inserted into the second transverse hole 16 through the third pin 17. When the connector 3 is in the first position, the third pin 17 is aligned with the second transverse hole 16, and the two can cooperate freely, making it easy to insert or remove the third pin 17 from the second transverse hole 16. When the connector 3 is rotated to the second position in the second transverse hole 16 through the rotating part on the third pin 17, the third locking part 18 on the third pin 17 is engaged with the side wall of the housing 2. At the same time, in the current position, the connector 3 is fixed by the fastener 4 and the lock 6 to prevent the connector 3 from rotating. Thus, they cooperate with each other, making it difficult for the housing 2 to be removed from the back hanger 1, thereby improving the anti-theft performance.

[0036] In one embodiment, such as Figure 11 and Figure 12 As shown, the back hanger 1 has a third connecting hole 19 on its side wall, and the connector 3 has a fourth connecting hole 20 corresponding to the third connecting hole 19; when the connector 3 is in the second position, the fourth connecting hole 20 is aligned with the third connecting hole 19; the lock 6 passes through the third connecting hole 19 and the fourth connecting hole 20 in sequence to fix it.

[0037] In this embodiment, by providing a third connecting hole 19 and a fourth connecting hole 20 on the side wall of the back hanger 1 and the connector 3 respectively, when the connector 3 is inserted into the second transverse hole 16 through the third pin 17 and rotated to the second position, the third connecting hole 19 and the fourth connecting hole 20 are aligned, and the lock 6 is fixed by passing through the third connecting hole 19 and the fourth connecting hole 20 in sequence, which facilitates installation and disassembly.

[0038] In one embodiment, such as Figures 1 to 3 , Figure 6 , Figure 9 , Figure 10 and Figure 12 As shown, the fastener 4 is a screw, the housing 2 has a threaded hole 5, and the connector 3 has a fifth connecting hole 21 corresponding to the threaded hole 5; the screw passes through the fifth connecting hole 21 and connects with the threaded hole 5 to fix the connector 3 and the housing 2.

[0039] In this embodiment, the fastener 4 is a screw, and a threaded hole 5 is provided on the housing 2. When installing the connector 3, the position of the fifth connecting hole 21 on the connector 3 can be adjusted to align with the threaded hole 5, and the screw can be threaded through the fifth connecting hole 21 and threadedly connected to the threaded hole 5.

[0040] In one embodiment, such as Figure 1 , Figure 6 and Figure 9 As shown, the external component is wall 23, and the back hanger 1 is bolted to wall 23.

[0041] In this embodiment, the external component is the wall 23, and the back hanger 1 is fixed to the wall 23 by bolt connection to improve the anti-theft performance and stability. This embodiment does not specifically limit the external component. The external component can also be a metal component. The back hanger 1 can be connected to the metal component by welding. The specific choice can be made according to actual needs.

[0042] Specifically, the back hanger 1 is fixed to the wall 23 by multiple expansion bolts 22.

[0043] In one embodiment, such as Figure 2 and Figure 12 As shown, the housing 2 is provided with multiple hooks 24 for hanging on the back hanger 1 via the hooks 24.

[0044] It should be noted that the hook 24 is positioned with its opening facing downwards, and the back hanger 1 is provided with a mating part that engages with the opening of the hook 24.

[0045] In this embodiment, the housing 2 is hung on the back hanger 1 by multiple hooks 24, which facilitates installation and disassembly and improves installation efficiency.

[0046] In one embodiment, connectors 3 are provided on both sides of the housing 2.

[0047] In this embodiment, connectors 3 are provided on both sides of the housing 2 to further improve the anti-theft performance.

[0048] Specifically, the connector 3 includes an integrally formed first connecting plate and a second connecting plate.
