As shown in fig. 1 to 13, the door stopper 1 includes a main substrate 5, the main substrate 5 includes a rectangular sheet-shaped substrate body 50, a guide screw 51 is disposed at a middle portion of the substrate body 50, a guide screw groove 52 is disposed on a side wall of the guide screw 51, a protruding insertion piece 53 is disposed at a head portion of the substrate body 50, a fixing hook 54 is disposed at a top portion of the insertion piece 53, a first hook hole 541 is disposed at a tail portion of the fixing hook 54, and a rack sliding groove 55 is disposed on an upper side wall of the substrate body 50.

The fixed hook 54 is provided with a rotatable movable hook 7, the tail of the movable hook 7 is provided with a second hook hole 71, the outer side wall of the second hook hole 71 is provided with a plurality of driving hook teeth 72, and the side wall of the movable hook 7 is provided with a torsion spring clamping column 73.

As shown in fig. 6, an annular pressure roller 6 is provided on the guide screw 51, and a pressure roller thread 61 is provided on an inner wall of the pressure roller 6, and the pressure roller thread 61 is engaged with the guide screw groove 52. A connecting pin 9 penetrates through the first hook hole 541 and the second hook hole 71, a return torsion spring 8 is disposed between the first hook hole 541 and the second hook hole 71, and the connecting pin 9 penetrates through the return torsion spring 8.

As shown in fig. 7, a slidable driving rack 11 is provided in the rack sliding groove 55, the driving rack 11 is engaged with the driving hook 72, and a pair of rack coupling holes 111 are provided at a distal end of the driving rack 11.

A slidable sliding block 10 is disposed on the top edge of the substrate main body 50, a sliding slot 101 is disposed at the bottom of the sliding block 10, a pair of sliding block holes 102 is disposed on the side wall of the sliding block 10, the driving rack 11 penetrates through the sliding slot 101, and the sliding block holes 102 and the rack connecting holes 111 are respectively connected through a rack screw 12.

As shown in fig. 1 to 5, the door panel 3 is matched with the door frame 2, a door lock panel 4 made of a metal sheet is disposed on a side wall of the door frame 2, and the door lock panel 4 is provided with a rectangular lock hole 41 into which a latch bolt is inserted.

The following description is provided for the usage of the gate stopper, which includes the steps:

step S1, the door panel 3 is opened, as shown in fig. 2 and 3, the user brings the door stopper 1 close to the door lock panel 4, so that the fixed hook 54 and the movable hook 7 face the lock hole 41;

step S2, as shown in fig. 10 and 11, the slide block 10 is shifted by a finger along the direction F1, so that the driving rack 11 slides towards the direction F1, the movable hook 7 starts to rotate along the direction R1 under the cooperation of the driving rack 11 and the driving teeth 72 of the movable hook 7, so that the fixed hook 54 and the movable hook 7 start to overlap and interleave, and at this time, the user extends the overlapped and interleaved fixed hook 54 and movable hook 7 into the lock hole 41 of the door lock panel 4;
