Further, the locking device 4 includes two rotating rods 42 respectively engaged with opposite ends of the driving member 43, and two locking catches 41 respectively corresponding to the two rotating rods 42 one by one. When the driving member 43 moves from the initial position to the locking position, the two locking hook sections 421 are driven to rotate in opposite directions, so as to be respectively locked to the corresponding lock catches 41. When the driving member 43 moves from the locking position to the initial position, the corresponding two latch hook sections 421 reversely rotate to disengage the corresponding catches 41.

Further, in the present embodiment, the driving inclined surface 431 is an end surface of the driving member 43 near the rotating rod 42, and the end of the driving section 422 away from the rotating shaft 423 abuts against the driving inclined surface 431, and at this time, the locking device 4 further includes a torsion spring 44 sleeved on the rotating shaft 423, where the torsion spring 44 provides an abutting force for the driving section 422 abutting against the driving inclined surface 431. So that the driving section 422 always contacts the driving inclined surface 431, and the rotating rod 42 can rotate simultaneously when the driving piece 43 slides, thereby simplifying the structure of the locking device 4 and enabling the movement of the rotating rod 42 to be smoother and stable. Of course, not limited to this, in other embodiments, a chute matching with the driving section 422 may be disposed on the driving member 43, and the driving inclined plane 431 may be a wall of the chute, where the torsion spring 44 may not be disposed.

In one embodiment, from the locking end 4311 to the unlocking end 4312, the driving ramp 431 extends obliquely toward the free end surface and away from the rotating lever 42. Therefore, when a user needs to take and put the articles in the cabinet 2 at the same time, the driving piece 43 can be moved to the locking position only by pulling the driving piece 43 forwards, so that the force application and operation of the user are facilitated. Of course, this is not a limitation.

Further, the locking device 4 further includes a reset member 45 disposed between the driving member 43 and the first door 11 or the second door 12 where the driving member 43 is disposed, where the reset member 45 drives the driving member 43 to reset to the initial position when the driving member 43 located at the locking position is not subjected to an external force. That is, when the driving member 43 is not subjected to an external force, the driving member 43 is always kept at the initial position, the locking device 4 is always kept at the unlocked state, and the second door body 12 can be opened independently; when a user needs to take and put the articles in the cabinet body 2 at the same time, an external force is applied to the driving piece 43, so that the driving piece 43 moves to a locking position, the locking hook section 421 is buckled with the lock catch 41, the locking device 4 is in a locking state, the first door body 11 and the second door body 12 are locked, and the second door body 12 is separated from the first door body 11 in the opening process of the first door body 11 can be avoided. In the process of opening and closing the first door 11, the user always needs to apply an external force to the driving member 43, so that the driving member 43 is maintained at the locking position.

It can be seen that, after the driving member 43 is located at the locking position, the user releases the driving member 43, that is, after the driving member 43 is not subjected to an external force, the driving member 43 moves toward the initial position under the action of the reset member 45, and meanwhile, under the action of the torsion spring 44, the rotating rod 42 rotates, and the driving section 422 is always abutted against the driving inclined surface 431, and the latch hook section 421 is separated from the corresponding latch 41.

In one embodiment, the restoring member 45 is a spring. Of course, this is not a limitation.

Further, the second free end surface 123 has a concave cavity 1231 concaved toward the second rotating end surface 122, a receiving cavity 1232 communicating with the concave cavity 1231 and used for receiving the driving member 43, the driving member 43 is slidably connected in the receiving cavity 1232, and the reset member 45 is disposed between the driving member 43 and the receiving cavity 1232. The second door 12 further has a through slot 124 which is communicated with the end of the accommodating cavity 1232 and penetrates the second door 12 toward the direction in which the first door 11 is located, the rotating rod 42 is rotatably connected in the through slot 124, and one end of the locking hook section 421 away from the rotating shaft 423 is exposed outside the second door 12. The user can operate the locking device 4 from the second free end face 123, so that the user can operate the locking device conveniently; and the locking device 4 is not exposed outwards, so that the appearance effect of the door body 1 is enhanced.

In the embodiment in which the driving bevel 431 extends obliquely from the locking end 4311 to the unlocking end 4312 toward the second free end face 123 and away from the rotating rod 42, the accommodating cavity 1232 is further located at a side of the concave cavity 1231 away from the first door body 11, the accommodating cavity 1232 is concavely formed from a communication port 1233 with the concave cavity 1231 toward the second free end face 123, and the reset member 45 is disposed at the front end of the driving member 43. When the driving piece 43 is located at the initial position, the driving piece 43 is located at the communication port 1233. When the first door 11 needs to be opened at the same time, the user only needs to pull the driving member 43 forward from the communication port 1233, so as to facilitate the application of force and operation of the user.

Further, the concave cavity 1231 forms the second handle portion 121 of the second door 12, facilitates the user's operation, and enhances the external appearance of the second door 12.

Further, in the embodiment in which the locking device 4 is provided on the door body 1, the first door body 11 may not be provided with the first handle portion 113, and the second handle portion 121 may be provided only on the second door body 12, and when the first door body 11 needs to be opened, the locking device 4 may be switched to the locked state, and then the first door body 11 may be opened by the second handle portion 121; when only the second door 12 needs to be opened, the locking device 4 is switched to the unlocked state, and at this time, the second door 12 can be opened alone by the second handle 121.
