[0021] like Figure 1-Figure 5The figure shows the first embodiment of the present invention, a magnetic door suction, comprising a base 1 mounted on a door panel and a floor suction piece 2 mounted on the ground, the base 1 being detachably connected to a cover 3, the bottom and back of the cover 3 being open, the base 1 being provided with a guide seat 101, the guide seat 101 being provided with a guide through hole 102, a movable rod 4 being provided in the guide through hole 102, the upper end of the movable rod 4 being provided with a boss 401, the lower end of the movable rod 4 being provided with a bottom cover 402, a magnet 5 being provided in the bottom cover 402, the movable rod 4 being sleeved with a spring 6, the upper end of the spring 6 being in contact with the boss 401, and the lower end being in contact with the guide seat 101, the floor suction piece 2 comprising a magnetic portion 201, the material of the magnetic portion 201 being a metal that can be magnetically attracted. The magnet 5 and the bottom cover 402 can be fixedly connected in various ways, such as magnetic attraction, bonding, fastener connection, etc. When opening the door, when the magnet 5 of the base 1 moves to above the magnetic part 201 of the floor suction piece 2, the magnet 5 will drive the movable rod 4 to compress the spring 6 and move downward to attract the magnetic part 201, thereby fixing the door. When closing the door, the magnet 5 moves with the door. When the magnet 5 and the magnetic part 201 are out of contact, the spring 6 pushes the movable rod 4 upward to return to its original position due to the elastic force.

[0022] The back of the housing 3 is provided with a protrusion 301, and the inner wall of the housing 3 is provided with a guide rail 302. A sliding groove 303 is formed between the protrusion 301 and the guide rail 302. The base 1 is provided with a slider 103 corresponding to the sliding groove 303. When the housing 3 is assembled, the slider 103 slides in the sliding groove 303 to provide guidance. After assembly, the slider 103 is stuck in the sliding groove 303, limiting the forward movement of the housing 3.

[0023] The sidewall of the housing 3 is provided with a snap-in notch 304, and the base 1 is provided with an elastic snap-in 7, which engages with the snap-in 304. In this embodiment, the base 1 is provided with a mounting slot 104, into which the elastic snap-in 7 is inserted. The elastic snap-in 7 is provided with an elastic swing arm 701, the end of which engages with the snap-in 304. To remove the housing 3, the elastic swing arm 701 is pressed inward to retract, thereby pulling the housing 3 upward.

[0024] A groove 105 is formed at the bottom of the base 1 , and the bottom cover 402 and the magnet 5 are placed in the groove 105 .

[0025] The bottom cover 402 is detachably connected to the movable rod 4. In this embodiment, a threaded hole is provided at the lower end of the movable rod 4, and a through hole is provided at the bottom cover 402. The movable rod 4 and the bottom cover 402 are connected by screws 9.

[0026] The floor suction piece 2 includes a stopper 202 , which is higher than the magnetic suction part 201 , so as to prevent the door from being pushed too far when the door is pushed into place.

[0027] like Figure 6 The figure shows the second embodiment of the present utility model, which differs from the first embodiment in that: the floor suction piece 2 also includes a base plate 203, the stopper 202 is a surrounding edge surrounding the base plate, and the magnetic part 201 is embedded in the surrounding edge and fixedly connected to the base plate. The stopper 202 is provided with a groove 204 for convenient disassembly of the magnetic sheet, and the base plate 203 is provided with a through hole 205 for installing screws. The floor suction piece in the first embodiment is suitable for direct bonding to the ground. If the ground is not suitable for bonding, the floor suction piece of the second embodiment is used, and the base plate 203 is fixed with screws. After the magnetic part 201 is placed in, it can cover the screws, which is more beautiful.

[0028] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Without departing from the spirit and scope of the present invention, simple modifications and substitutions by those skilled in the art are within the scope of protection of the present invention.
