The main body shell is a columnar structure, and a column sliding cavity is arranged in the main body shell. A limiting fixing cap is installed on the upper end of the column sliding cavity. The movable column passes through and slides inside the column sliding cavity, and the top of the movable column is limited by the limiting fixing cap. A boss is provided on the movable column, and a reset spring is sleeved on the movable column. One end of the reset spring is connected to the boss, and the other end of the reset spring is connected to the bottom wall of the column sliding cavity. An installation groove is also provided at the bottom of the movable column, and a magnet is provided in the installation groove, and the magnetic sheet cooperates with the magnet by magnetic attraction.

[0006] Preferred technical solution 1: An installation adjustment groove is provided on one side of the main shell, a fixed adjustment piece is slidably provided in the installation adjustment groove, and a screw installation hole is provided on the fixed adjustment piece for fixing the door stopper to the door by screws.

[0007] Preferred technical solution 2: A friction groove is further provided on one side of the fixed adjustment member, and a friction block is provided in the friction groove to increase the friction between the main housing and the fixed adjustment member when adjusting the relative height between the main housing and the fixed adjustment member.

[0008] Preferred technical solution three: An arc-shaped stopper is provided on the magnetic attraction sheet to limit the position of the magnet.

[0009] Preferred technical solution four: The column sliding cavity is also provided with reinforcing ridges to increase the overall strength of the main body shell.

[0010] Preferred technical solution five: The magnetic sheet is a stainless steel magnetic sheet, which is fixed to the ground by double-sided tape.

[0011] The utility model proposes a new type of door stopper which is convenient to use. The beneficial effects achieved by adopting the above structure are as follows:

[0012] (1) The door stopper can be installed flexibly and can be fixed to the door body by screws. At the same time, the height can be adjusted by installing the adjustment slot and the fixed adjustment piece, which greatly reduces the requirements for installation height accuracy;

[0013] (2) Through the cooperation of the magnetic sheet, the movable column, the magnet and the reset spring, when in use, the magnet and the magnetic sheet are attracted to each other, so that the movable column moves downward and is fixed by the arc-shaped stopper, thereby limiting the door.

[0024] Embodiment 1

[0025] like Figures 1 to 6 As shown, the technical scheme adopted by the utility model is as follows: a new type of door stopper that is easy to use, including a main body shell 1, a movable column 2 and a magnetic suction piece 3. The main body shell 1 is a columnar structure. A column sliding cavity 4 is arranged in the main body shell 1. A limited fixing cap 5 is installed on the upper end of the column sliding cavity 4. The movable column 2 passes through and is slidably arranged in the column sliding cavity 4. The top of the movable column 2 is limited by the limited fixing cap 5. A boss 6 is arranged on the movable column 2. A return spring 7 is sleeved on the movable column 2. One end of the return spring 7 is connected to the boss 6, and the other end of the return spring 7 is connected to the bottom wall of the column sliding cavity 4. An installation groove 8 is also opened at the bottom of the movable column 2. A magnet 9 is arranged in the installation groove 8. The magnetic suction piece 3 cooperates with the magnet 9 by magnetic attraction; an arc-shaped stopper 15 is arranged on the magnetic suction piece 3 for limiting the magnet. The magnetic suction piece 3 is a stainless steel magnetic suction piece 3, which is fixed to the ground by double-sided tape; a reinforcing convex rib 16 is also arranged in the column sliding cavity 4 to increase the overall strength of the main body shell 1.

[0026] Embodiment 2

[0027] Based on the first embodiment, Figures 3 to 5 As shown, an installation adjustment groove 10 is provided on one side of the main shell 1, and a fixed adjustment piece 11 is slidably provided in the installation adjustment groove 10. The fixed adjustment piece 11 is provided with a screw installation hole 12 for fixing the door stopper on the door by screws; a friction groove 13 is also provided on one side of the fixed adjustment piece 11, and a friction block 14 is provided in the friction groove 13 to increase the friction between the main shell 1 and the fixed adjustment piece 11 when adjusting the relative height.

[0028] During specific use, the screws are passed through the screw mounting holes 12 to fix the door body, and the magnetic sheet 3 can be adhered to the ground by double-sided tape. During use, the door body is pushed and pulled so that the main shell 1 is located directly above the magnetic sheet 3, and the magnet 9 is adsorbed on the magnetic sheet 3. At the same time, the magnet 9 drives the movable column 2 to move downward, so that the reset spring 7 is compressed, and at the same time, the magnet 9 is limited and fixed by the arc-shaped stop block 15 to complete the limited fixation of the door body. When pushed away from the door body, it is subjected to the rebound force of the reset spring 7, so that the movable column 2 is retracted into the column sliding cavity 4.
