The following describes the embodiments of the present invention based on its overall structure.

[0025] Reference Figures 1 to 6 In an embodiment of the present invention, a door stopper that is easy to install and use includes: a mounting base 1 and a mounting base 2. A magnetic trapezoidal seat 3 is provided on the top of the mounting base 1. A cross-shaped rubber block 301 is fixedly connected to the top surface of the magnetic trapezoidal seat 3. Anti-skid particles 302 are provided on the top surface of the cross-shaped rubber block 301. A magnetic trapezoidal seat 4 is provided on the top of the mounting base 2. A magnetic rod 401 is fixedly connected to the center of the top surface of the magnetic trapezoidal seat 4.

[0026] The mounting base 1 also includes a suction cup seat 101, a mounting suction cup 102, a suction hole 103, a threaded ring 104, a threaded cover 105, a connecting column 106, a suction cup 107, a telescopic cylinder 108, a connecting spring 109, a positioning round head rod 110 and a closing groove 111.

[0027] Reference Figure 2 The suction cup seat 101 is set as a cylindrical seat structure, and a rubber mounting suction cup 102 is fixed to its bottom end. A threaded ring 104 is fixed on the outer side of the suction cup seat 101, and a threaded cover 105 is screwed on the outer side of the threaded ring 104.

[0028] The above solution is adopted: the door suction structure is fixed to the wall or door and window through the installation suction cup 102 at the bottom of the suction cup seat 101. The installation method is convenient, and the threaded ring 104 on the outside of the suction cup seat 101 is screwed to the threaded cover 105, that is, the suction cup structure and the top door suction structure are designed as a split type, which is convenient for the quick disassembly and replacement of the rubber installation suction cup 102 when it weathers and cracks during use.

[0029] Reference Figure 3 A suction hole 103 is opened through the center of the suction cup seat 101, a connecting column 106 is fixed to the center of the threaded cover 105, and a suction cup 107 is fixed to the bottom end of the connecting column 106. The suction hole 103 is adapted to the specifications of the suction cup 107.

[0030] Adopting the above solution: the installation suction cup 102 is adsorbed on the wall or door and window and then pressed tightly, and the threaded cover 105 is rotated to pull the suction cup 107 out of the suction hole 103, thereby increasing the internal and external pressure difference of the installation suction cup 102, improving the adsorption force of the installation suction cup 102, and making the installation connection more stable.

[0031] Reference Figure 4 A telescopic cylinder 108 is fixedly connected to the center of the bottom surface of the suction disc 107, a connecting spring 109 is fixedly connected to the top of the telescopic cylinder 108, and a positioning round head rod 110 is fixedly connected to the bottom end of the connecting spring 109. The positioning round head rod 110 and the telescopic cylinder 108 are telescopically connected to each other.

[0032] The above solution is adopted: the positioning round head rod 110 set at the bottom end of the suction cup 107 can be extended into the preset round head groove on the wall or door and window during installation, and the positioning round head rod 110 is kept tightly connected by the telescopic cylinder 108 and the connecting spring 109, so that it can still be pressed in the preset round head groove during the movement of the threaded cover 105, thereby improving the stability of the fixed position of the mounting seat structure and avoiding the displacement of the door suction structure due to moisture on the wall or door and window.

[0033] Reference Figure 5 The top surface of the threaded cover 105 is provided with a closing groove 111 with a top notch, and the closing groove 111 is compatible with the specifications of the magnetic trapezoidal seat 1 3 and the magnetic trapezoidal seat 2 4.

[0034] Adopting the above solution: the closing groove 111 is adapted to the specifications of the magnetic trapezoidal seat 1 3 and the magnetic trapezoidal seat 2 4. While limiting the engagement, the magnetic trapezoidal seat 1 3 and the magnetic trapezoidal seat 2 4 can still be rotated after applying a certain external force so that the notch of the connected cross-shaped rubber block 301 is aligned with the position of the magnetic rod 401.

[0035] Reference Figures 1 to 6 The mounting base 2 2 has the same composition structure as the mounting base 1 1, that is, it is also provided with the same number and specifications of suction cup seats 101, mounting suction cups 102, suction holes 103, threaded rings 104, threaded covers 105, connecting columns 106, suction cups 107, telescopic cylinders 108, connecting springs 109, positioning round head rods 110 and closing grooves 111 structures.

[0036] With the above solution, the first mounting base 1 and the second mounting base 2 are respectively installed on the wall or door or window through the same convenient and effective structure.

[0037] Reference Figure 5 and Figure 6 The cross-shaped rubber block 301 is set as a rubber block structure with a cross-shaped horizontal cross-section, and the notch specifications in the cross-shaped rubber block 301 are adapted to the specifications of the end of the magnetic rod 401. The number of anti-slip particles 302 is set in several groups and is evenly arranged on the top surface of the cross-shaped rubber block 301.

[0038] The above solution is adopted: the cross-grooved design of the cross-shaped rubber block 301 enables it to have a buffering and supporting effect on the magnetic rod 401 regardless of whether it is installed on a horizontal ground or a vertical wall. When it is installed on the horizontal ground, the magnetic rod 401 is inserted into the groove of the cross-shaped rubber block 301 and cooperates with the magnetic structure to be adsorbed and fixed. When installed on a vertical wall, the magnetic rod 401 and the top surface of the cross-shaped rubber block 301 provided with anti-slip particles 302 are abutted. The anti-slip particles 302 increase the friction between the magnetic rod 401 and the cross-shaped rubber block 301 to prevent the magnetic rod 401 from slipping out of the buffering and supporting range of the cross-shaped rubber block 301.

[0039] The working principle of the present invention is as follows: when in use, the door suction structure is fixed to the wall or door and window through the installation suction cup 102 at the bottom of the suction cup seat 101. The installation method is convenient, and the threaded ring 104 on the outside of the suction cup seat 101 is screwed to the threaded cover 105, that is, the suction cup structure and the top door suction structure are designed as a split type, which is convenient for use. When the rubber material installation suction cup 102 is weathered and cracked during use, it can be quickly disassembled and replaced. After the installation suction cup 102 is adsorbed on the wall or door and window, it is pressed tightly and the threaded cover 105 is rotated. The suction cup 107 is pulled out from the suction hole 103, increasing the internal and external pressure difference of the installation suction cup 102, improving the adsorption force of the installation suction cup 102, and making the installation connection more stable. The positioning round head rod 110 set at the bottom end of the suction cup 107 can be extended into the round head groove preset on the wall or door and window during installation, and the positioning round head rod 110 is kept tightly connected by the telescopic cylinder 108 and the connecting spring 109, so that it can still be pressed in the preset round head groove during the movement of the threaded cover 105, thereby improving the installation base structure. The stability of the fixed position of the structure is ensured to avoid the displacement of the door suction structure due to moisture on the wall or doors and windows. The closing groove 111 is compatible with the specifications of the magnetic trapezoidal seat 1 3 and the magnetic trapezoidal seat 2 4. While limiting the engagement, the magnetic trapezoidal seat 1 3 and the magnetic trapezoidal seat 2 4 can still be rotated after applying a certain external force to align the notch of the connected cross-shaped rubber block 301 with the position of the magnetic rod 401. The cross-grooved design of the cross-shaped rubber block 301 makes it stable whether it is installed on a horizontal ground or a vertical wall. It has a buffering and supporting effect on the magnetic rod 401. When it is installed on the horizontal ground, the magnetic rod 401 is inserted into the groove of the cross-shaped rubber block 301 and cooperates with the magnetic structure to be adsorbed and fixed. When it is installed on a vertical wall, the magnetic rod 401 and the top surface of the cross-shaped rubber block 301 provided with anti-slip particles 302 are against each other. The anti-slip particles 302 increase the friction between the magnetic rod 401 and the cross-shaped rubber block 301 to prevent the magnetic rod 401 from slipping out of the buffering and supporting range of the cross-shaped rubber block 301.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
