[0003] Current drawer locks usually need to be unlocked manually, which sometimes causes inconvenience in daily use and cannot meet higher usage requirements, so there is a need for improvement. Summary of the invention

[0004] The present invention provides a bedside table drawer lock that can be electrically unlocked and can realize password or fingerprint unlocking, etc., thereby increasing convenience during use and meeting higher usage requirements; it solves the technical problems in the prior art that the current drawer lock has a single structure, usually requires manual unlocking, sometimes causes inconvenience, and cannot meet higher usage requirements.

[0005] The above technical problem of the present invention is solved by the following technical solution: a bedside drawer lock, comprising a lock body, wherein a lock plate that can be lifted and lowered longitudinally is provided in the lock body, a lock tongue is provided at the bottom of the lock plate, the end of the lock tongue penetrates the lock body and extends to the outside, a lock rod that can drive the lock plate to be lifted and lowered is provided on one side of the lock body, a driving member connected to the lock rod is provided on the outside of the lock body, and an emergency lock structure is also provided in the lock body. In the locked state, the end of the lock tongue extends downward to the lock body for locking, and when unlocking, the driving member drives the lock rod to lift the lock plate and drives the lock tongue to retract into the lock body for unlocking, and the emergency lock structure is used for emergency unlocking when the driving member and other structures fail.

[0006] Preferably, the driving member comprises a driving motor fixed on the outside of the lock body, a driving shaft of the driving motor extends into the lock body, a driving block is fixedly sleeved on the driving shaft of the driving motor, and a locking rod is eccentrically fixed on the driving block. When unlocking, the driving motor drives the locking rod to rotate, and as the locking rod rotates, the locking rod gradually drives the locking plate and the locking tongue to rise to unlock, and when unlocking, the driving motor drives the locking rod to reverse downward, the locking plate and the locking tongue are reset downward, and the locking tongue extends out of the lock body to lock again.

[0007] Preferably, a guide rod is provided inside the lock body, the top of the guide rod extends to the lock body, and the lock tongue is fixed to the bottom of the guide rod. The guide rod serves to provide guidance for the lifting and lowering of the lock plate, and the lock plate, the lock tongue and the guide rod can be lifted and lowered synchronously.

[0008] Preferably, the guide rod outer sleeve is provided with a reset spring, and the reset spring is located outside the guide rod between the lock plate and the lock body. In the locked state, the lock tongue extends downward to the lock body, and the reset spring is not compressed. When unlocking, the drive motor drives the lock rod to rotate. As the lock rod rotates, the lock rod will gradually drive the lock plate, the guide rod, and the lock tongue to rise. At this time, the reset spring will be gradually compressed. When unlocking, the drive motor drives the lock rod to reverse downward. The lock plate, the guide rod, and the lock tongue are quickly reset and moved downward under the action of the reset spring, and the lock tongue extends out of the lock body to lock again.

[0009] Preferably, a micro switch cooperating with the lock plate is provided on one side of the lock body, and the reed of the micro switch faces downward. When unlocking, the driving motor drives the lock rod to rotate, and as the lock rod rotates, the lock rod gradually drives the lock plate, the guide rod and the lock tongue to rise, and the reset spring is gradually compressed at this time, until the lock plate compresses the reed of the upper left micro switch, and the driving motor stops working.

[0010] Preferably, the emergency lock structure comprises an emergency lock plate rotatably mounted in the lock body, one end of the emergency lock plate extends outside the lock body, and the other end of the emergency lock plate abuts against the bottom of the lock plate. When manual emergency unlocking is required under special circumstances, the emergency lock plate on the left side of the lock body can be manually pulled, and the end of the emergency lock plate will lift the lock plate upwards for emergency unlocking.

[0011] Therefore, a bedside table drawer lock of the present invention has the following advantages: it can cooperate with a circuit board to realize password or fingerprint unlocking, and realize electric quick unlocking through a motor, thereby increasing convenience during use and meeting higher usage requirements.

[0018] In the figure, there are lock body 1, guide rod 2, lock plate 3, return spring 4, lock tongue 5, drive motor 6, drive block 7, lock rod 8, micro switch 9, and emergency lock plate 10. DETAILED DESCRIPTION

[0019] The technical solution of the invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0020] Example:

[0021] like Figure 1 and 2 As shown in 3, 4, 5 and 6, a bedside table drawer lock comprises a lock body 1, a guide rod 2 which can slide longitudinally is installed on the top of the lock body 1, the top of the guide rod 2 extends to the outside of the lock body 1, a lock plate 3 which extends transversely is fixed to the bottom of the guide rod 2, and a return spring 4 is installed on the outer shell of the guide rod 2 between the lock plate 3 and the lock body 1.

[0022] A lock tongue 5 is fixedly mounted on the bottom of the lock plate 3 , and the bottom end of the lock tongue 5 extends through and out of the lock body 1 .

[0023] A driving component that can drive the lock plate 3 to rise and fall is installed on the right side of the lock body 1. The driving component includes a driving motor 6 fixedly installed on the right side of the lock body 1. The driving shaft of the driving motor 6 extends to the left into the body. A driving block 7 is fixedly installed outside the driving shaft of the driving motor 6. A locking rod 8 is eccentrically installed on the driving block 7. The locking rod 8 extends to the bottom of the lock plate 3.

[0024] A micro switch 9 is fixedly installed on the upper left of the lock body 1, and the reed of the micro switch 9 is installed downward.

[0025] An emergency lock structure is also installed in the lock body 1, and the emergency lock structure includes an emergency lock plate 10 rotatably installed on the left side of the lock body 1, the left end of the emergency lock plate 10 extends outside the lock body 1, and the right end of the emergency lock plate 10 abuts against the bottom of the lock plate 3.

[0026] When in use, the driving motor 6 can drive the driving shaft and the driving block 7 to rotate, and the locking rod 8 on the driving block 7 will rotate around the axial direction of the driving shaft. When in the locked state, the locking tongue 5 extends downward to the outside of the lock body 1, and the reset spring 4 is not compressed. When unlocking, the driving motor 6 drives the locking rod 8 to rotate. As the locking rod 8 rotates, the locking rod 8 will gradually drive the locking plate 3, the guide rod 2, and the locking tongue 5 to rise. At this time, the reset spring 4 will be gradually compressed until the locking plate 3 compresses the reed of the upper left microswitch 9, and the driving motor 6 stops working.

[0027] When unlocking, the driving motor 6 drives the locking rod 8 to reverse downward, and the lock plate 3, the guide rod 2 and the lock tongue 5 are quickly reset and moved downward under the action of the reset spring 4, and the lock tongue 5 extends out of the lock body 1 to lock again.

[0028] When manual emergency unlocking is required under special circumstances, the emergency lock plate 10 on the left side of the lock body 1 can be manually pulled, and the end of the emergency lock plate 10 will lift the lock plate 3 upwards to perform emergency unlocking.
