Wherein the lock case 100 is installed on the drawer, the latch bolt 500 is movably coupled to the lock case 100 and located at the inner side of the drawer, the flip cover 300 is pivotally coupled to the lock case 100 and located at the outer side surface of the drawer, and the locking mechanism 200 is disposed in the lock case 100.

When the drawer is closed and the latch tongue 500 is extended to a locking position engaged with the cabinet, the flip cover 300 is flush with the surface of the lock case 100 to be in a closed position, so as to be flush with the outer surface of the drawer.

When the cover 300 is in the closed position, it does not occupy the space outside the drawer and shields the lock case 100, thereby providing a hidden and beautiful effect.

The locking mechanism 200 has a locked state and an unlocked state. When the locking mechanism 200 is in the locked state, the cover 300 is locked in the closed position, as shown in fig. 1 and 4. When the locking mechanism 200 is in the unlocked state, as shown in fig. 1 and 5, the flip cover 300 can be rotated in the first direction I from the closed position to open, and simultaneously move the locking bolt 500 from the locked position to the unlocked position.

That is, when the locking mechanism 200 is unlocked, the lifting cover 300 is pulled to unlock the drawer.

In order to facilitate pulling the lifting cover 300, a notch is formed on the lifting cover 300 to serve as a handle, and the handle can pull the lifting cover 300 to rotate along the first direction I by pulling the lifting cover 300 from the notch.

Therefore, the lock provided by the application not only occupies small space on the surface of the drawer cabinet, is concealed and attractive, but also is convenient to use, and can finish unlocking and pulling actions at one time.

The lock case 100 may be one-piece or detachably assembled.

In this embodiment, referring to fig. 1, fig. 2, fig. 3 and fig. 4, the lock case 100 includes a first case 110 and a second case 120, the first case 110 and the second case 120 are integrally connected and then installed on the drawer cabinet, wherein the first case 110 is close to the outer side of the drawer, and the second case 120 is close to the inner side of the drawer.

Referring to fig. 3, the first housing 110 includes a bottom wall, side walls, and a front end wall 111, and the second housing 120 includes a top wall and a rear end wall. The first housing 110 and the second housing 120 form a receiving chamber in the middle when they are coupled.

Referring to fig. 5, 6 and 7, the connection between the flip cover 300 and the first housing 110 is formed with a boss 330 facing the first housing 110 on both sides of the flip cover 300, and a first rotating shaft 310 is disposed on the boss 330, and the first rotating shaft 310 is connected to a sidewall of the first housing 110.

The aforementioned notch on the lifting cover 300 is located at one end, and the other end of the lifting cover 300 is connected with a transmission member 400, and the transmission member 400 is used for driving the lock tongue 500 when the lifting cover 300 rotates along the first direction I.

The notch and the transmission member 400 are respectively located at the upper and lower sides of the first rotating shaft 310, and the distance between the notch and the first rotating shaft 310 is greater than the distance between the transmission member 400 and the first rotating shaft 310. Therefore, when the end with the notch is pulled and opened and rotated, the transmission member 400 at the other end can be pried by taking the first rotating shaft 310 as a fulcrum, that is, when the lock is opened, the lifting cover 300 is equivalent to a labor-saving lever, and a labor-saving effect can be achieved.

To further reduce the moment arm between the transmission member 400 and the first rotating shaft 310, the latch tongue 500 is installed opposite to the flip cover 300, i.e., the latch tongue 500 is located at the rear of the lock case 100 near the rear end wall of the second housing 120. The locking bolt 500 can move up to the locked position and can move down to the unlocked position. The transmission member 400 extends from the lifting cover 300 to be close to the latch 500 along a direction perpendicular to the lifting cover 300, so as to prevent the transmission member 400 from increasing the resistance arm of the lifting cover 300, and further achieve the effect of saving labor. Moreover, if increase apart from between driving medium 400 and the spring bolt 500, not only can not lead to digging to move and lift lid 300 more hard, but also can make spring bolt 500 set up the position in the more depths of drawer, be difficult to by violence unblock, be favorable to improving theftproof performance.

In the locked position, the first lock member 210 protrudes downward beyond the lower portion of the front end wall 111 of the first housing 110, such that the lower end of the first lock member 210 corresponds to the lower portion of the front end wall 111, so as to be able to cooperate with the second lock member 340 on the flip cover 300, thereby restricting the flip cover 300 from being pulled up in the first direction I.

The first lock 210 can reach the unlocking position by moving upward from the locking position, so that the second lock 340 can pass through, and the flip cover 300 can be pulled up.

The locking tip 250 has a first position and a second position. In the first position, the locking top 250 occupies space to prevent the first locking member 210 from moving to the unlocked position; in the second position, the locking top 250 allows room to allow the first locking member 210 to move to the unlocked position.

In one embodiment, the locking top 250 is a cam, and the motor 240 drives the cam to rotate between the first position and the second position. In the first position, the lobe of the cam aligns with the first locking member 210 to prevent the first locking member 210 from moving upward; in the second position, the cam's recess aligns with the first latch 210 to make room for the first latch 210 to move up to unlock.

In the present embodiment, the locking head 250 is moved in the left and right direction by the motor 240. In other embodiments, the locking top 250 may be driven by the motor 240 to move in the front-back direction.

The rotating shaft of the motor 240 and the locking top piece 250 can also be connected through a spring, the spring is sleeved on the rotating shaft, a protrusion is formed on the rotating shaft, the protrusion is located in a track of the spring, and one end of the spring, which is far away from the motor 240, is connected with the first locking piece 210. When the motor 240 rotates forward, the protrusion on the rotating shaft moves along the track of the spring to drive the locking top 250 connected with the rotating shaft to extend out to the upper part of the first locking element 210 along the rotating shaft. When the motor 240 rotates reversely, the protrusion on the rotating shaft moves along the track of the spring to drive the locking top part 250 connected with the protrusion to retract along the rotating shaft, so as to leave the space above the first locking part 210.

To further facilitate unlocking, the locking mechanism 200 further includes a circuit board 230 and a wake-up switch 231 disposed on the circuit board 230.

The circuit board 230 is provided with a bluetooth control circuit, the bluetooth control circuit is used for controlling the motor 240 to rotate, and the wake-up switch 231 is used for waking up the bluetooth control circuit.

After the bluetooth control circuit is awakened, the mobile phone can be used to connect the bluetooth control circuit, so that an unlocking instruction is sent to the bluetooth control circuit on the mobile phone to control the motor 240 to rotate, and the locking top piece 250 moves from the first position to the second position.

The wake-up switch 231 is disposed on the circuit board 230 and configured to extend from the inside of the lock case 100, so that the wake-up switch 231 is triggered when the flip cover 300 is rotated from the closed position in the second direction II towards the lock case 100.

In the present embodiment, through holes corresponding to the wake-up switch 231 are provided in both the lock cylinder case 112 to which the lock mechanism 200 is mounted and in the front end wall 111 of the first housing 110, so that the wake-up switch 231 can extend out of the lock case 100 through both the through holes by the circuit board 230.

To facilitate indicating whether the circuit board 230 is normally activated, an indicator light 232 is disposed on the circuit board 230, and when the circuit board 230 is activated, the indicator light 232 is illuminated. Similarly, through holes of the indicator 232 are correspondingly formed in the lock box 112 where the locking mechanism 200 is installed, the front end wall 111 of the first housing 110 and the flip cover 300, and a light guide column is disposed in each through hole, so that light of the indicator 232 passes through the light guide column for easy observation.

Therefore, when the lock is unlocked, the flip cover 300 is pressed to trigger the wake-up switch 231, the mobile phone controls the locking mechanism 200 to unlock, the lock can be unlocked and the drawer can be pulled out by pulling the flip cover 300, and the unlocking step is simple.

The first locking member 210 is configured as shown in fig. 11, and the first locking member 210 includes a locking column 211, and a lower end of the locking column 211 is configured as a ball 212.

During unlocking, the locking top piece 250 is in the second position, the flip cover 300 is pulled to rotate along the first direction I from the closed position, the side, which is not provided with the inclined surface 341, of the second locking piece 340 presses the ball 212 of the first locking piece 210, so that the first locking piece 210 moves upwards from the locking position to the unlocking position, and the second locking piece 340 is unlocked by crossing the first locking piece 210.

In order to cooperate with the lifting cover 300, the lifting cover 300 automatically returns to the closed position after being unlocked, and the lifting cover 300 is prevented from randomly swinging at the moment. A third elastic reset element 220 is arranged in the lock, and the third elastic reset element 220 acts on the first locking element 210 and is used for driving the first locking element 210 to return to the locking position. When the cover 300 rebounds to the closed position, the third elastic resetting member 220 drives the first locking member 210 to reset, so as to cooperate with the second locking member 340 to limit the cover 300 from swinging arbitrarily. In this embodiment, the third elastic restoring element 220 is a spring sleeved on the locking post 211. In other embodiments, the third elastic restoring element 220 may also be a spring or other elastic element.

On the basis of restricting the flip cover 300 to swing freely, in order to lock next time, the situation that the bluetooth control circuit is forgotten to be operated to lock is avoided, and the bluetooth control circuit is configured to: after the unlocking, the motor 240 is controlled to be locked again after a predetermined time has elapsed. That is, the locking top 250 is moved from the second position to the first position so that the locking top 250 can lock the first locking member 210 when the first locking member 210 returns to the locking position.

In order to be able to conveniently close and lock the flip cover 300 in the case that the bluetooth control circuit has controlled the lock top 250 to move to the first position by the motor 240 and locked the first lock 210.

The second locking member 340 is movably disposed on the flip cover 300 and elastically moves by the fourth elastic restoring member 350. During the rotation of the flip cover 300 to the closed position along the second direction II, the first latch 210 presses the second latch 340 to move against the elastic force of the fourth elastic restoring member 350, so that the second latch 340 can pass over the first latch 210.

As shown in fig. 4 and 5, the second locking member 340 is cylindrical and has a slope 341 at one end. The boss 330 of the flip cover 300 is provided with a third mounting hole 331, one end of the second locking member 340 having the inclined plane 341 extends from the third mounting hole 331, the other end is located in the third mounting hole 331, the third mounting hole 331 is provided with a sealing cover 332, and a fourth elastic resetting member 350 is arranged between the sealing cover 332 and the other end of the second locking member 340, so that the second locking member 340 elastically moves relative to the boss 330 of the flip cover 300. Therefore, in the process that the flip cover 300 rotates to the closed position along the second direction II, the first locking member 210 presses the inclined surface 341 on the second locking member 340, so that the second locking member 340 elastically moves to pass over the first locking member 210; after the second locking member 340 passes over the first locking member 210, a surface of the second locking member 340 facing away from the inclined surface abuts against the first locking member 210 to prevent the lift cover 300 from opening along the first direction I.
