[0029] Reference Figures 1 to 6As shown, a drawer lock is provided, including a base 1 and a sub-buckle seat 4, a female buckle 2 is provided on the base 1, one end of the female buckle 2 is rotatably connected to the base 1, an elastic member 3 is installed at the connection between the female buckle 2 and the base 1, the other end of the female buckle 2 is snap-connected with the sub-buckle seat 4, a protrusion 21 is provided at one end of the female buckle 2 close to the base 1, a limiting portion 11 is provided at one end of the base 1 close to the female buckle 2, and the protrusion 21 can be rotatably snapped into the limiting portion 11.

[0030] Furthermore, the base 1 is installed on the inner side of the drawer near the handle, and the sub-buckle seat 4 is installed on the inner wall surface of the drawer top. When closing the drawer, when the drawer is closed to the best position where the fingers can just be inserted, release the fingers pressing the female buckle 2, and then slightly force the female buckle 2 to stick to the inner wall surface of the drawer top; when the drawer needs to be opened, pull the drawer out until the fingers can be inserted and press the female buckle 2, insert the fingers to press the female buckle 2, so that the female buckle 2 and the sub-buckle seat 4 are unlocked and can be opened; when the lock is not used, just press the female buckle 2 downward until the protrusion 21 on the female buckle 2 is stuck in the limiting part 11 of the base 1, which can prevent infants and young children of a certain age from opening the drawer without understanding the operating principle of the lock; when the female buckle 2 is pasted to the inner wall surface of the drawer top, due to the action of the elastic member 3, the top of the female buckle 2 will be close to the inner wall surface of the drawer top.

[0031] Embodiment 1:

[0032] like Figures 1 to 3 As shown, a first hook portion 43 is provided on the top of the sub-buckle seat 4, and the first hook portion 43 and the top of the sub-buckle seat 4 form a clamping space, and the opening direction of the clamping space is toward the inside of the drawer, and an end of the female buckle 2 away from the base 1 is provided with a first clamping portion 23 which is clamped with the first hook portion 43. Because the base 1 is installed on the inner side of the drawer close to the handle, when the drawer is pulled, the female buckle 2 on the base 1 will follow the displacement, and when it is pulled out to a certain position, the first clamping portion 23 on the female buckle 2 is just clamped into the clamping space, so that the female buckle 2 and the sub-buckle seat 4 are buckled with each other, thereby locking the drawer.

[0033] Preferably, in order to better facilitate the connection between the mother buckle 2 and the child buckle seat 4, the first hook portion 43 is arranged to be inclined downward, and in order to better cooperate with the first hook portion 43, the first clamping portion 23 is also arranged to be inclined downward following the first hook portion 43. After buckling, the surface of the first clamping portion 23 fits with the surface of the first hook portion 43.

[0034] Preferably, a rectangular hole is provided on the female buckle 2 along the length of the female buckle 2, and the rectangular hole and the inner wall of the female buckle 2 form an active space 24. The first hook portion 43 passes through the active space 24 and is engaged with the first clamping portion 23. When the female buckle 2 is pulled with the drawer, the first hook portion 43 can move back and forth in the active space 24. When the drawer is closed, the first hook portion 43 moves in the active space 24 toward the base 1. When the drawer is opened, the first hook portion 43 moves toward the first clamping portion 23 and is engaged with the first clamping portion 23.

[0035] Embodiment 2:

[0036] like Figures 4 to 6 A second hook 22 is provided at one end of the female buckle 2 away from the base 1, and a second clamping portion 41 is protruded from the top of the sub-buckle seat 4. The second clamping portion 41 is recessed inward to form a groove 42, and the second hook 22 is engaged with the groove 42. When the second hook 22 is close to the inner wall surface of the top of the drawer, the drawer is pulled outward to open, and the second hook 22 will be stuck in the groove 42, so that the drawer cannot be opened.

[0037] Preferably, the female buckle 2 is provided with a protruding block 26 near the second hook portion 22, and the second clamping portion 41 is provided with an assembly groove 45 that cooperates with the protruding block 26. The protruding block 26 is inserted into the assembly groove 45, and the installation can be easily achieved without using other tools when installing the base 1 and the sub-buckle seat 4.

[0038] In one embodiment of the utility model, a limit block 25 is provided on the top of the female buckle 2, and the limit block 25 abuts against the limit portion 11 to prevent the female buckle from bouncing up due to the elastic force of the elastic member 3 when the drawer is fully opened, thereby preventing the person opening the drawer from being frightened or injured.

[0039] In one embodiment of the utility model, one end of the elastic member 3 abuts against the bottom of the female buckle 2, and the other end of the elastic member 3 abuts against the base 1. Preferably, the elastic member 3 adopts a torsion spring to make the female buckle 2 and the base 1 abut against each other.

[0040] In one embodiment of the utility model, double-sided stickers 6 are pasted on the bottom of the base 1 and the bottom of the buckle seat 4. The method for installing the base 1 and the buckle seat 4 is as follows: after controlling the distance between the double-sided sticker 6 at the bottom of the buckle seat 4 and the inner wall surface of the top of the drawer to be zero, do not tear off the protective layer of the double-sided sticker 6 first, and then paste the double-sided sticker 6 at the bottom of the base 1 on the inner side of the drawer near the handle. At this time, tear off the protective layer of the double-sided sticker 6 at the bottom of the buckle seat 4 and paste it on the inner wall surface of the top of the drawer.

[0041] In one embodiment of the utility model, two symmetrical first assembly holes 12 are provided on the base 1, and the base 1 is fixed to the inner side of the drawer near the handle by screw connection. Two symmetrical second assembly holes 44 are also provided on the sub-buckle seat 4, and the sub-buckle seat 4 is installed on the inner wall surface of the top of the drawer by screw connection.

[0042] In one embodiment of the utility model, the female buckle 2 is rotatably connected to the base 1 via a rotating shaft 5. The rotating shaft 5 enables the female buckle 2 to rotate more smoothly. The rotating shaft 5 passes through the elastic member 3 and is installed at the connection between the female buckle 2 and the base 1.

[0043] In one embodiment of the utility model, an indication mark 7 is provided on the top of the female buckle 2, and the indication mark 7 guides the operator to use it.
