[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0050] To make the above objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0051] Referring to Figures 1 to 8 , the present invention discloses an AC / DC integrated electrical cabinet with an anti-theft function, including:

[0052] A frame body 1, the frame body 1 includes two integrally formed side plates, and the front side and the back side of the frame body 1 are respectively provided with a front side opening and a back side opening;

[0053] A back plate 15, installed in the back side opening, a stop strip 16 is fixedly connected to the inner edge of the back side opening, the stop strip 16 is in limit fit and fixed with the edge of the back plate 15, and the back plate 15 is located inside the frame body 1;

[0054] A front panel 3, one end of the front panel 3 is hinged to one side of the inner edge of the front side opening, and the other end of the front panel 3 is connected to the frame body 1 through a door lock;

[0055] An anti-theft component 5, covering the outside of the door lock, and the anti-theft component 5 is fixedly connected to the frame body 1.

[0056] During use, the back plate 15 is installed on the back side of the frame body 1 from the inside of the frame body 1. The back plate 15 is fixed to the frame body 1 through the stop strip 16 fixedly connected to the inner edge of the back side opening, and the back plate 15 is flush with the outer surface of the back side of the frame body 1. On the one hand, the gap is reduced, and on the other hand, the screws are installed from the inside of the frame body 1 to avoid the situation of the back plate 15 being disassembled from the outside, improving the anti-theft performance. Moreover, the two side plates of the frame body 1 are of an integrally formed structure. The front side of the frame body 1 is hinged to the front panel 3 through a hinge, and then the opening and closing state of the front panel 3 and the frame body 1 is controlled by a door lock. The anti-theft component 5 covering the outside of the door lock can only be disassembled by a special tool, which can play a role in preventing the lock from being pried and improve the anti-theft effect, and can avoid the loss of batteries or electrical components inside the frame body 1.

[0057] A lifting ring 2 is fixedly connected to the top of the frame body 1.

[0058] As an optional implementation manner, the anti-theft component 5 includes:

[0059] An anti-theft buckle plate 501, covering the outside of the door lock, and internal threaded holes are provided at the four corners of the anti-theft buckle plate 501;

[0060] An anti-theft part, installed in the internal threaded hole, and the anti-theft buckle plate 501 is fixed to the frame body 1 through the anti-theft part.

[0061] As an optional implementation manner, the anti-theft part includes:

[0062] A screw sleeve 504, one end of the screw sleeve 504 is provided with an external thread, the other end of the screw sleeve 504 is provided with an internal thread, and the screw sleeve 504 is fixedly embedded in the frame body 1 through the external thread;

[0063] The screw 503 is threadedly fixed to the internal thread of the screw sleeve 504, and the anti-theft buckle plate 501 is clamped between the end cap of the screw 503 and the frame body 1;

[0064] The anti-theft nut 502 is provided with an external thread on the outside. The anti-theft nut 502 is in threaded fit with the internal thread hole, and the anti-theft nut 502 is sleeved on the outside of the screw 503.

[0065] As an optional implementation manner, a washer 505 is sleeved on the screw 503. One side of the washer 505 is in limit fit with the end cap of the screw 503, and the other side of the washer 505 is in limit fit with the anti-theft buckle plate 501. The anti-theft buckle plate 501 is clamped between the washer 505 and the frame body 1.

[0066] After the front panel 3 is closed, it is connected to the frame body 1 through a door lock. At this time, the anti-theft buckle plate 501 is covered on the outside of the door lock. The screw sleeve 504 is pre-embedded in the frame body 1. The anti-theft buckle plate 501 is fixed to the outside of the frame body 1 through the cooperation of the screw 503 and the washer 505. Subsequently, the anti-theft nut 502 is screwed into the internal thread hole through a special tool. The anti-theft nut 502 can only be installed and removed using a special tool, so it has an anti-theft effect.

[0067] The anti-theft nut 502 and the special tool can be obtained through market procurement.

[0068] Furthermore, the anti-theft nut 502 includes two ramp grooves 507 opened at one end of the anti-theft nut 502 away from the screw 503. The two ramp grooves 507 are symmetrically arranged. A cavity 512 is opened at one end of the anti-theft nut 502 close to the screw 503. A sliding cavity 513 is opened in the middle of the anti-theft nut 502. A spline piston 511 is slidably connected in the sliding cavity 513. The sliding cavity 513 is in radial limit fit with the spline piston 511. One end of the spline piston 511 close to the screw 503 is in limit fit with the screw 503 through a spline groove 506. The spline groove 506 is opened on the end cap of the screw 503. A spring 508 is arranged in the sliding cavity 513. One end of the spring 508 is fixedly connected to the inner wall of the sliding cavity 513, and the other end of the spring 508 is fixedly connected to the spline piston 511. An electromagnetic heating coil 509 is sleeved outside the sliding cavity 513. The electromagnetic heating coil 509 is embedded in the anti-theft nut 502. The positive electrode and the negative electrode of the electromagnetic heating coil 509 are electrically connected to two electrode plates through wires respectively. The two electrode plates are respectively embedded in the corresponding ramp grooves 507. The external thread direction of the anti-theft nut 502 is opposite to the thread direction of the screw 503.

[0069] During use, after the screw 503 is tightened, the anti-theft nut 502 is tightened. As the anti-theft nut 502 approaches the screw 503, the magnetic core 510 is magnetically connected to the screw 503, stretching the spring 508. The spline piston 511 is inserted into the spline groove 506, so that the anti-theft nut 502 and the screw 503 are in limit fit. Since the external thread direction of the anti-theft nut 502 is opposite to the thread direction of the screw 503, before the limit function of the anti-theft nut 502 and the screw 503 is released, neither the anti-theft nut 502 nor the screw 503 can rotate.

[0070] When it needs to be removed, the positive electrode and the negative electrode of the power supply are respectively inserted into the ramp groove 507 and electrically connected to the electromagnetic heating coil 509, so that the electromagnetic heating coil 509 heats the magnetic core 510, and the magnetism of the magnetic core 510 disappears. Under the action of the spring 508, the spline piston 511 is separated from the spline groove 506. At this time, by using a special wrench that is in limit fit with the ramp groove 507, the anti-theft nut 502 can be rotated.

[0071] The anti-theft nut 502 is made of high-strength and heat-resistant ABS plastic material.

[0085] The battery compartment 9 and the controller compartment 8 do not interfere with each other; air enters through the second air inlet 6, passes through the battery compartment 9, and is discharged through the second exhaust port 17.
