[0029] Example

[0030] Reference Figure 1-2 As shown, this utility model discloses a child lock for a drawer 30, including a base 10 and a fixing plate 20. The base 10 includes a housing 101 and a bottom plate 102. Specifically, the bottom plate 102 has several positioning holes, and the housing 101 is provided with positioning rods. The bottom plate 102 and the housing 101 are assembled into one unit by the cooperation of the positioning rods and the positioning holes. The bottom plate 102 has mounting holes, and the base 10 is installed on the inner end face of the drawer 30 through the mounting holes of the bottom plate 102.

[0031] Reference Figure 3-7 As shown, the housing 101 has a cavity 1011, which has an upper notch 1012 and a side notch 1013. A swingable hook 1022 and a lever 1024 are installed on one side of the base plate 102. The hook 1022 is placed inside the cavity 1011 and extends out of the upper notch 1012, while the lever 1024 extends out of the side notch 1013. A counterweight 1023 is provided at one end of the hook 1022 near the base plate 102, and the lever 1024 is rotatably positioned on the side near the counterweight 1023. The lever 1024 has a top abutment 1025. Specifically, the base plate 102 and the housing 101 are installed on the inner end face of the drawer 30, with the base plate 102 having a top abutment 1025 on one side facing the housing 101. A U-shaped fixing plate 1021 is placed, and a hook 1022 and a lever 1024 are rotatably set inside the U-shaped fixing plate 1021. The counterweight 1023 always faces downward under the action of gravity, so that the hook of the hook 1022 always extends out of the upper notch 1012 of the cavity 1011. The lever 1024 extends out from the side notch 1013 of the cavity 1011. Rotating the lever 1024 causes the top abutment 1025 to push the counterweight 1023 of the hook 1022, so that the hook of the hook 1022 sinks into the cavity 1011 from the upper notch 1012. By rotating the lever 1024, the hook of the hook 1022 sinks into the cavity 1011, so that the hook 1022 will not hook the slot 201.

[0032] Reference Figure 8As shown, the fixing plate 20 has mounting holes and a slot 201. The mounting holes are used to fix the fixing plate 20 to the bottom of the drawer 30 cabinet 40. When the hook 1022 extends out of the upper notch 1012, the hook of the hook 1022 of the drawer 30 will hook into the slot 201 to prevent the drawer 30 from opening. When the hook 1022 sinks into the cavity 1011 from the upper notch 1012, the drawer 30 can move in and out freely, which is convenient for adults to use.

[0033] The further fixing plate 20 has positioning posts on both sides of the slot 201, and the housing 101 has positioning grooves on both sides of the cavity 1011. Since the base 10 and the fixing plate 20 are installed on the drawer 30 and the cabinet 40 respectively, they are used together and are also sold together. By inserting the positioning posts into the positioning grooves, the two are fixed together to avoid loss and unusability due to separation.

[0034] In other embodiments, the counterweight 1023 is a magnet, and the base plate 102 is provided with a fixed magnet in the direction of the counterweight 1023. The fixed magnet will attract the counterweight magnet, so that the hook part of the hook 1022 is deep into the upper notch 1012 of the cavity 1011. That is, when the drawer 30 is pulled out in the normal state, the hook of the hook 1022 will hook the slot 201 to prevent children from opening the drawer 30.

[0035] In other embodiments, adhesive tape is provided on the base plate 102 and the base 10. The base plate 102 and the base 10 are fixed by adhesive tape, which avoids damage to the drawer 30 caused by the installation and fixing by screws, and the installation is convenient.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
