[0025] The utility model will be further described in detail in combination with the embodiment of the drawings.

[0026] As Figures 1-6 The embodiment of the utility model for the gravity overturning locking device of the safety cabinet includes the sliding plate 2 that can move transversely relative to the cabinet door 1 and the lock 3 that blocks the transverse movement of the sliding plate 2, wherein the sliding plate 2 is the conventional design in the lock structure of the safety cabinet door 1, and the transverse movement of the sliding plate 2 drives the extension and retraction of the latch head 6 connected with the sliding plate 2 to determine whether the cabinet door 1 is locked or not. And the cabinet door 1 is connected with the hinge seat pre-set on the cabinet body of the safety cabinet through the hinge shaft 11, and since the connection mode of the hinge shaft 11 and the hinge seat is adopted, if the cabinet door 1 is opened in the inverted state of the safety cabinet, the hinge shaft 11 of the cabinet door 1 will be separated from the hinge seat under the action of gravity, causing the cabinet door 1 to fall.

[0027] Therefore, the gravity overturning locking device of the embodiment is provided with the sliding pin 4 that can move longitudinally relative to the cabinet door 1 on the cabinet door 1, and the sliding pin 4 can move longitudinally and abut against the side wall of the sliding plate 2 to block the transverse movement of the sliding plate 2 in the inverted state of the safety cabinet, so that the safety cabinet is always in the locked state in the inverted state, avoiding the falling of the cabinet door 1 due to the separation of the hinge shaft 11 when the cabinet door 1 is opened.

[0028] As Figures 2-5As shown, the gravity overturning locking device further comprises a limiting assembly 5 for limiting the sliding pin 4, which comprises a mounting box 51 and a limiting rod 52. The sliding pin 4 is arranged in the mounting box 51, and a longitudinally extending strip-shaped hole 53 is formed in the mounting box 51. One end of the limiting rod 52 is connected to the sliding pin 4, and the other end extends out of the mounting box 51 from the strip-shaped hole 53 and can move longitudinally in the strip-shaped hole 53. The longitudinally extending strip-shaped hole 53 can limit the longitudinal movement distance of the limiting rod 52, so that the limiting rod 52 can only move between the first end 53a and the second end 53b of the strip-shaped hole 53. In the upright state of the safe cabinet, as shown in Figures 2-3 the limiting rod 52 is located at the first end 53a of the strip-shaped hole 53, and at this time the sliding pin 4 is limited at the first position away from the sliding plate 2 and does not block the sliding plate 2. In this state, the lock 3 is unlocked, and the sliding plate 2 can be moved transversely to open the cabinet door 1. In the inverted state of the safe cabinet, due to the action of gravity, the sliding pin 4 and the limiting rod 52 move longitudinally, and the limiting rod 52 moves to the second end 53b of the strip-shaped hole 53. At this time, the sliding pin 4 extends out of the limiting box and is limited at the second position against the side wall of the sliding plate 2. In this state, the sliding plate 2 is always blocked by the sliding pin 4, and the cabinet door 1 is always in a locked state, and even if the lock 3 is unlocked, the sliding plate 2 cannot be moved to open the cabinet door 1.

[0029] As shown in Figure 1 and Figure 6 in this embodiment, the lock 3 comprises a circular password device 31 arranged on the front surface of the cabinet door 1 and capable of controlling the transformation of the lock 3 between the locked state and the unlocked state, an electromagnet 32 arranged on the back surface of the cabinet door 1 and electrically connected with the password device 31, and a driving assembly 33 acting on the sliding plate 2 and capable of driving the sliding plate 2 to move transversely in the unlocked state of the lock 3. The output end of the electromagnet 32 is provided with a top rod 34. In the locked state of the lock 3, the top rod 34 abuts against the side wall of the sliding plate 2 and can block the transverse movement of the sliding plate 2. In the unlocked state of the lock 3, the electromagnet 32 is powered to attract the top rod 34 to make the top rod 34 move longitudinally to release the block of the sliding plate 2. Since the electromagnet 32 is used to attract the top rod 34 to release the block of the sliding plate 2 when the locked state is transformed into the unlocked state, in the inverted state of the safe cabinet, violent knocking or vibration of the electromagnet 32 is easy to cause the electromagnet 32 to fail. The above-mentioned sliding rod can make the cabinet door 1 always in the locked state in the inverted state of the safe cabinet, so that even if the electromagnet 32 is damaged by violence, the cabinet door 1 cannot be opened, and the safety performance of the safe cabinet is improved.

[0030] Further, the driving assembly 33 comprises a rotating member 331 sleeved on the passworder 31 and capable of rotating relative to the passworder 31, and a transmission assembly 332 arranged on the back of the cabinet door 1 and connected with the rotating member 331, the transmission assembly 332 being connected with the sliding plate 2 and capable of converting the rotation of the rotating member 331 into the lateral movement of the sliding plate 2. The transmission assembly 332 comprises a cam 3321 arranged on the rotating shaft of the rotating member 331, and a transmission shaft 3322 arranged on the cam 3321 and arranged in a different axis with the rotating shaft of the rotating member 331, and the sliding plate 2 is longitudinally provided with a first sliding slot 21 for the transmission shaft 3322 to pass through. The transmission shaft 3322 arranged in a different axis with the rotating member 331 can make the rotating shaft of the rotating member 331 and the axis of the transmission shaft 3322 have a certain distance, so that when the rotating member 331 rotates, the transmission shaft 3322 can move laterally and longitudinally, thereby acting on the sliding plate 2 to make the sliding plate 2 move laterally, and the first sliding slot 21 longitudinally arranged provides the transmission shaft 3322 with a space for longitudinal movement. The cabinet door 1 is further provided with a fixed shaft 35 perpendicular to the cabinet door 1, and the sliding plate 2 is laterally provided with a second sliding slot 22 for the fixed shaft 35 to pass through. The arrangement of the fixed shaft 35 plays a supporting and limiting role in the vertical position of the sliding plate 2, and the cooperation of the fixed shaft 35 and the second sliding slot 22 provides a guide for the lateral movement of the sliding plate 2, and meanwhile, the length of the second sliding slot 22 also limits the distance of the lateral movement of the sliding plate 2.
