Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example: Figure 1-5 As shown, the utility model provides an anti-pinch component for doors and windows, including a door frame 1, a door panel 11 is rotatably installed in the door frame 1, a mounting plate 2 is detachably installed on the inner wall of one side of the door frame 1, and is used for installing fixed boxes 3 of different sizes, and a fixed box 3 is detachably installed on the side of the mounting plate 2, and is used for storing a shielding cloth 32; a winding roller 31 is rotatably installed in the fixed box 3, and a shielding cloth 32 is provided on the outer surface of the winding roller 31, and a fixing plate 34 is fixedly installed on the end of the shielding cloth 32 away from the winding roller 31, and the fixing plate 34 is movably adhered to the door panel 11 away from the side of the fixing box 3.

[0021] The upper and lower ends of the winding roller 31 are rotatably arranged inside the fixed box 3, and the outer surfaces of the upper and lower ends of the winding roller 31 are fixedly installed with second springs 33, and one end of the second spring 33 away from the winding roller 31 is fixedly connected to the fixed box 3 to drive the winding roller 31 to rotate. When in use, when the door panel 11 is opened, the fixed plate 34 is driven to make a circular motion, and the movement of the fixed plate 34 pulls the shielding cloth 32 to move. At this time, the winding roller 31 rotates, and the second spring 33 is deformed under the action of external force. When the door panel 11 is closed, the second spring 33 releases the deformation force, driving the winding roller 31 to rotate.

[0022] By adopting the above technical solution, the second spring 33 can drive the winding roller 31 to rotate.

[0023] A movable plate 23 is slidably installed in the mounting plate 2, a second screw 25 is rotatably installed in the mounting plate 2, and the movable plate 23 is threadedly connected to the second screw 25, and mounting blocks 24 are fixedly installed on the sides of the movable plate 23 and the mounting plate 2 away from the door frame 1, and the sides of the two mounting blocks 24 close to each other are in active contact with the upper and lower sides of the fixed box 3 to limit the fixed box 3. When in use, when the upper and lower ends of the fixed box 3 are clamped in the mounting blocks 24, the fixed box 3 cannot move, so that the fixed box 3 can be limited.

[0024] By adopting the above technical solution, the mounting block 24 can limit the fixing box 3 .

[0025] A rotating rod 27 is rotatably installed in the mounting plate 2, and a second bevel gear 28 is fixedly installed at the center of one end of the rotating rod 27 close to the second screw rod 25, and a first bevel gear 26 is fixedly installed at the center of the bottom end of the second screw rod 25, and the first bevel gear 26 and the second bevel gear 28 are meshed with each other to drive the second screw rod 25 to rotate. When in use, the second bevel gear 28 is rotated by the rotation of the rotating rod 27, the first bevel gear 26 is rotated by the rotation of the second bevel gear 28, and the second screw rod 25 is rotated by the rotation of the first bevel gear 26.

[0026] By adopting the above technical solution, the rotating rod 27 can drive the second screw rod 25 to rotate.

[0027] An adhesive pad 35 is movably inserted in the fixing plate 34, and the adhesive pad 35 is adhered to the door panel 11 away from the side of the fixing box 3, so as to install the fixing plate 34. When in use, when the adhesive pad 35 is adhered to the door panel 11, the installation of the fixing plate 34 is completed.

[0028] By adopting the above technical solution, the adhesive pad 35 can be installed on the fixing plate 34 .

A slider 37 is fixedly mounted on the lower surface of the limit block 36, and the slider 37 is slidably arranged inside the fixed plate 34. A magnetic sheet 38 is fixedly mounted on the top end of the fixed plate 34 to limit the adhesion pad 35. When in use, when the lower surface of the limit block 36 is in contact with the upper surface of the adhesion pad 35, the adhesion pad 35 cannot move, thereby limiting the adhesion pad 35.

[0030] By adopting the above technical solution, the limiting block 36 can limit the adhesion pad 35 .

[0031] Two fixing blocks 21 are fixedly installed on both sides of the mounting plate 2, and the fixing blocks 21 are internally threadedly connected with screw rods 22, and the ends of the screw rods 22 away from the fixing box 3 are threadedly connected to the inside of the door frame 1 for installing the mounting plate 2. When in use, when the screw rods 22 are screwed into the inside of the door frame 1, the installation of the mounting plate 2 is completed.

[0032] By adopting the above technical solution, the screw rod 22 can be used to install the mounting plate 2.

[0034] By adopting the above technical solution, the limiting rod 16 can block the door panel 11 .

[0035] Working principle: First, screw the screw rod 22 into the door frame 1 to complete the installation of the mounting plate 2, and then insert the bottom end of the fixing box 3 into the mounting block 24 on the mounting plate 2;

[0036] Secondly, the rotation of the rotating rod 27 drives the second bevel gear 28 to rotate, and the rotation of the second bevel gear 28 drives the first bevel gear 26 to rotate, and the rotation of the first bevel gear 26 drives the second screw 25 to rotate, and the rotation of the second screw 25 drives the moving plate 23 to move, and the movement of the moving plate 23 drives the mounting block 24 located on the moving plate 23 to move, so that the lower surface of the mounting block 24 contacts the upper surface of the fixed box 3, and the top end of the fixed box 3 is now stuck inside the mounting block 24 on the moving plate 23, and the installation of the fixed box 3 is completed;

[0037] Then, the adhesive pad 35 is inserted into the fixing plate 34, and the limiting block 36 is pushed to move so that the lower surface of the limiting block 36 contacts the upper surface of the adhesive pad 35, and the adhesive pad 35 is limited, and then the adhesive pad 35 is adhered to the door panel 11, and the installation of the fixing plate 34 is completed;

[0038] Finally, when in use, when the door panel 11 is opened, the door panel 11 drives the fixed plate 34 to make a circular motion, and the movement of the fixed plate 34 pulls the shielding cloth 32 to move, so that the shielding cloth 32 blocks the gap between the door panel 11 and the door frame 1, thereby preventing children from putting their fingers into the gap and reducing safety hazards.

[0039] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
