[0020] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0021] See Figures 1-5 This embodiment discloses a child anti-pinch device, which includes a mounting base and a magnetic button 10. The mounting base is mounted on the drawer, and the magnetic button 10 is separately disposed from the mounting base.

[0022] An anti-pinch component 20 is rotatably mounted inside the mounting base. The anti-pinch component 20 includes a stop tongue 22 and a first magnetic chamber 23. The anti-pinch component 20 can reciprocate between the anti-pinch position and the release position. When the anti-pinch component 20 is in the anti-pinch position, the stop tongue 22 extends out of the mounting base. When the anti-pinch component 20 is in the release position, the stop tongue 22 retracts into the mounting base. A second magnetic chamber 321 is formed on the mounting base. A first magnet 231 is installed in the first magnetic chamber 23, and a second magnet 3211 is installed in the second magnetic chamber 321. A third magnet 11 is installed in the magnetic button 10. The second magnet 3211 and the first magnet 231 repel each other, providing the anti-pinch component 20 with a first magnetic force to rotate to the anti-pinch position. The third magnet 11 and the first magnet 231 attract each other, providing the anti-pinch component 20 with a second magnetic force to rotate to the release position. The second magnetic force is greater than the first magnetic force. When in use, to achieve the anti-pinch function, simply remove the magnetic button 10, and the anti-pinch component 20 will rotate to the anti-pinch position, exposing the stop tongue 22, preventing the drawer from closing completely. To fully close the drawer, simply bring the magnetic button 10 close to the mounting base, and the anti-pinch component 20 will rotate to the release position, retracting the stop tongue 22, allowing the drawer to close completely. The anti-pinch component 20 is movably mounted on the mounting base, and through the cooperation of three magnets, it can be rotated to the anti-pinch or release position as needed, making it convenient to use and highly adaptable.

[0023] The anti-pinch component 20 is equipped with a hinge shaft 24, which is hinged to the mounting base. The anti-pinch component 20 rotates around the hinge shaft 24. The stop tongue 22 and the first magnetic cavity 23 are respectively located on both sides of the hinge shaft 24. The anti-pinch component 20 also includes a main body block 21, which includes a first end face 211, a second end face 212, and a third end face 213. The hinge shaft 24 is formed at the angle between the first end face 211 and the second end face 212. The stop tongue 22 is formed above the first end face 211, and the first magnetic cavity 23 is formed at the bottom of the second end face 212. The anti-pinch component 20 is integrally formed, with reasonable distribution of the functional structures and a compact overall structure.

[0024] The mounting base includes a rear seat 31 and a front panel 32 fastened to the front of the rear seat 31. The rear seat 31 and the front panel 32 together define an assembly cavity for accommodating the anti-pinch component 20. The second magnetic compartment 321 is formed at the bottom of the front panel 32. A front window 322 is provided in the center of the front panel 32 to expose the first magnetic compartment 23, thereby increasing the magnetic force and improving the reliability of the anti-pinch device. The rear seat 31 includes a front wall 311, two side walls 312 and a rear wall 313. The front panel 32 is detachably fastened to the front wall 311. The rear seat 31 and the front panel 32 are separately arranged to facilitate the assembly of the anti-pinch component 20. The anti-pinch component 20 is located between the two side walls 312. The inner sides of the two side walls 312 are each formed with a hinge groove 3121 that mates with the hinge shaft 24.

[0025] To further improve the ease of use of the anti-pinch device, a first latch 25 is formed at the bottom of the third end face 213 of the main body block 21, and a second latch 323 is formed at the top of the second magnetic compartment 321 to cooperate with the first latch 25. When the drawer needs to be completely closed for a long time, the two latches can be used to lock the anti-pinch component 20 in the release position. When anti-pinch is needed, the two latches can be released to allow the anti-pinch component 20 to rotate freely again. There is no need to frequently disassemble and assemble the anti-pinch device, making it convenient to use. To facilitate the cooperation of the two latches, a lever 26 is formed in the middle of the third end face 213 of the main body block 21, and an arc-shaped hole 3131 is provided on the rear wall 313 of the rear seat 31 to allow the lever 26 to move. By moving the lever 26, the cooperation state of the two latches can be changed.
