[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Please see Figures 1-5 As shown, this utility model is a safe with an alarm function, comprising: Cabinet 100, cabinet 100 is rotatably connected to cabinet door 300, cabinet door 300 is equipped with intelligent control system, intelligent control system is existing structure and will not be described here; The triggering mechanism includes a motor 210, a rotating shaft 220, a pull plate 230, a spring plate 240, an L-shaped rod 250, a push rod 260, a flip plate 270, and a pressure sensor 280. Motor 210 is fixedly connected to one side of the inner wall of cabinet door 300. Rotary shaft 220 is fixedly connected to the power output end of motor 210. Pull plate 230 is fixedly connected to the end of rotary shaft 220. Spring plate 240 is slidably connected to the top and bottom surfaces of cabinet body 100 at both ends. L-shaped rod 250 is fixedly connected to the back of spring plate 240. Push rod 260 is fixedly connected to the short side wall of L-shaped rod 250. Flip plate 270 is rotatably connected to the side wall of cabinet body 100 in the middle. Pressure sensor 280 is fixedly connected to the middle of the side wall of cabinet body 100. When cabinet door 300 is opened using a password, the intelligent control system inside cabinet door 300 controls motor 210. The start-up mechanism drives the rotating shaft 220 to rotate, causing the pull plate 230 to rotate vertically and pass through the square hole on the surface of the spring plate 240. When the cabinet door 300 is forcibly pried open, the cabinet door 300 tilts up, causing the motor 210, rotating shaft 220, and pull plate 230 to move. The pull plate 230 pulls the spring plate 240, causing it to bend and deform in the middle. The deformation of the spring plate 240 causes the L-shaped rod 250 to move. The L-shaped rod 250 causes the push rod 260 to move, pushing the bottom of the flip plate 270 and causing the flip plate 270 to rotate in the middle. The other end of the flip plate 270 flips and contacts the pressure sensor 280, triggering an alarm. The alarm will only be triggered when a thief forcibly pries open the cabinet door 300. The triggering mechanism also includes a reset assembly, which includes a fixed plate 291, a connecting plate 292, a first telescopic rod 293, and a first spring 294. The reset assembly restores the flipped 270. The fixed plate 291 is fixedly connected to the side wall of the cabinet 100. The first telescopic rod 293 and the first spring 294 are fixedly connected to the side wall of the fixed plate 291 and the side wall of the connecting plate 292 respectively. The connecting plate 292 is rotatably connected to one end of the bottom surface of the flip plate 270. When the push rod 260 pushes the bottom of the flip plate 270 to move, the flip plate 270 and the connecting plate 292 rotate, and the connecting plate 292 moves at the same time. The movement of the connecting plate 292 compresses the first telescopic rod 293 and the first spring 294. When the alarm ends and the cabinet door 300 is closed, the spring plate 240 rebounds and restores, causing the L-shaped rod 250 and the push rod 260 to slide in opposite directions. At this time, the first spring 294 rebounds and causes the flip plate 270 to flip and restore, and the first telescopic rod 293 is stretched. The bottom and top surfaces of the cabinet 100 are respectively fixedly connected to a lower hanging plate 110. The surface of the lower hanging plate 110 is provided with a sliding groove 111. A corner plate 410 is slidably connected in the sliding groove 111. A horizontal plate 112 is fixedly connected to the top front of the lower hanging plate 110. A second telescopic rod 420 and a second spring 430 are fixedly connected to the bottom surface of the horizontal plate 112. The other ends of the second telescopic rod 420 and the second spring 430 are respectively fixedly connected to the top surface of one end of the corner plate 410. The other end of the corner plate 410 is fixedly connected to the spring plate 240. When the pull plate 230 causes the spring plate 240 to bend in the middle, the two ends of the spring plate 240 slide. The spring plate 240 causes the corner plate 410 to slide, which causes the second telescopic rod 420 and the second spring 430 to be pulled up, so that the spring plate 240 can bend fully. A communication module 510 and an alarm 520 are fixedly connected to the inner wall of the cabinet 100. The communication module 510, the alarm 520 and the pressure sensor 280 are connected together by wires. When the bottom of the flip plate 270 contacts the pressure sensor 280, the information is transmitted to the communication module 510 through the wires, so that the communication module 510 controls the alarm 520 to sound an alarm through the wires. Working principle: When cabinet door 300 is opened via password, the intelligent control system inside cabinet door 300 controls motor 210 to start, driving shaft 220 to rotate, causing pull plate 230 to rotate vertically and pass through the square hole on the surface of spring plate 240. Normal opening of cabinet door 300 will not trigger an alarm. When cabinet door 300 is forcibly pried open, cabinet door 300 tilts up, causing motor 210, shaft 220, and pull plate 230 to move. Pull plate 230 pulls spring plate 240, bending and deforming it in the middle, causing both ends of spring plate 240 to slide. The ends of spring plate 240 drive corner plate 410 to slide, causing second telescopic rod 420 and second spring 430 to rise, allowing spring plate 240 to bend fully. The bending and deformation in the middle of spring plate 240 causes L-shaped rod 250 to move. When the L-shaped rod 250 moves, it drives the push rod 260 to move, pushing the bottom of the flip plate 270. This causes the flip plate 270 and the connecting plate 292 to rotate, while simultaneously moving the connecting plate 292. The movement of the connecting plate 292 compresses and drives the first telescopic rod 293 and the first spring 294, causing the middle of the flip plate 270 to rotate. When the other end of the flip plate 270 flips and contacts the pressure sensor 280, it triggers an alarm. When the bottom of the flip plate 270 contacts the pressure sensor 280, the information is transmitted to the communication module 510 through a wire. The communication module 510 then controls the alarm 520 to sound an alarm through the wire. This ensures that the alarm is only triggered when a thief forcibly pries open the cabinet door 300, preventing the alarm from being triggered by excessive force when closing the door or accidental impact, thus reducing the false alarm rate.

[0018] Please see Figures 1-5 As shown, this embodiment, based on the above embodiment, further includes: The fixing mechanism includes a round tube 610, a short connecting rod 620, a long connecting rod 630, a threaded plate 640, and a lead screw 650. A circular tube 610 is fixedly connected to one end surface of a corner plate 410. A short connecting rod 620 is rotatably connected to the side wall of the circular tube 610. One end of a long connecting rod 630 is rotatably connected to the other end of the short connecting rod 620. A threaded plate 640 is slidably connected inside the circular tube 610. The other end of the long connecting rod 630 is rotatably connected to the side wall of the threaded plate 640. A lead screw 650 is rotatably connected inside the circular tube 610 and threadedly connected to the threaded plate 640. By default, the short connecting rod 620 and the long connecting rod 630... To achieve linear contraction on the side wall of the circular tube 610, after the two ends of the spring plate 240 pass through the circular tube 610, the screw 650 is rotated to drive the threaded plate 640 to slide. The threaded plate 640 drives one end of the long connecting rod 630 to move, causing the other end of the long connecting rod 630 to rotate and open with the end of 320, and causing the other end of the short connecting rod 620 to rotate on the side wall of the circular tube 610, so that the short connecting rod 620 opens to fit against the surface of the spring plate 240, and the spring plate 240 is fixed to one end of the corner plate 410. The side wall of the round tube 610 is provided with a side groove 611, and the side wall of the threaded plate 640 is fixedly connected with a protrusion 641. The protrusion 641 slides in the side groove 611. The top of the screw 650 is fixedly connected with a rotating handle 651. The rotating handle 651 facilitates the rotation of the screw 650. The protrusion 641 restricts the threaded plate 640 to slide only in the side groove 611 and prevents it from rotating with the screw 650. The side wall of the protruding plate 641 is provided with a second rotating groove 642, one end of the long connecting rod 630 is provided with a first rotating groove 631, the other end of the long connecting rod 630 rotates in the second rotating groove 642, one end of the short connecting rod 620 rotates in the first rotating groove 631, when the threaded plate 640 drives the protruding plate 641 to slide in the side groove 611, one end of the long connecting rod 630 rotates in the second rotating groove 642 and moves accordingly, the other end of the long connecting rod 630 drives the end of the short connecting rod 620 to open and rotate in the first rotating groove 631; Working principle: When the spring plate 240 is violently pried and breaks, the reverse rotating handle 651 drives the lead screw 650 to reverse. The lead screw 650 drives the threaded plate 640 to slide upward. The threaded plate 640 drives the convex plate 641 to slide upward in the side groove 611. This causes one end of the long connecting rod 630 to rotate in the second rotating groove 642 while sliding upward. The other end of the long connecting rod 630 drives one end of the short connecting rod 620 to retract and causes one end of the short connecting rod 620 to rotate in the first rotating groove 631, causing the short connecting rod... The other end of 620 rotates on the side wall of the round tube 610. When the round tube 610 and the short connecting rod 620 are brought together into a straight line, the two ends of the damaged spring plate 240 are removed from the round tube 610. Then, the two ends of the new spring plate 240 are passed through the round tube 610. Similarly, the rotating handle 651 is rotated to drive the lead screw 650 to rotate in the forward direction, so that the short connecting rod 620 is opened to fit against the surface of the spring plate 240. The spring plate 240 is fixed to one end of the corner plate 410, thus completing the quick replacement of the spring plate 240.
