[0046] The floor suction base assembly 2 includes a floor suction base outer cover 21, a sound-absorbing soft rubber 22, a floor suction plate 23, a connecting shaft 24, a sound-absorbing pad 25 and a base fixing seat 26; the floor suction base outer cover 21 is provided with a floor suction base outer cover buckle 211 and an outer cover disassembly port 212; the sound-absorbing soft rubber 22 is provided with a sound-absorbing soft rubber opening 221; the floor suction plate 23 is provided with a suction plate connecting ring 231 and a suction plate curling 232; the base fixing seat 26 is provided with a connecting shaft embedding groove 261, a sound-absorbing pad connecting hole 262, a base screw hole 263 and a chamfered buckle 264, Both ends of the connecting shaft groove 261 are provided with connecting buckles 2611; the connecting shaft 24 is embedded in the suction plate connecting ring 231, and then embedded in the connecting shaft groove 261 in the base fixing seat 26 together with the suction plate connecting ring 231, and the connecting buckle 2611 fixes the connecting shaft 24 and the suction plate connecting ring 231 in the connecting shaft groove 261; the silencer pad 25 is fixed to the base fixing seat 26 through the silencer pad connecting hole 262; the silencer soft rubber 22 is inserted into the middle part of the ground suction plate 23, which can reduce the noise generated by the ground suction plate 23 colliding with the magnet 16.

[0047] Under normal circumstances, the ground suction plate 23 on the base of the magnetic silent windproof ground suction of the present invention is in a horizontal state, and the buckle tongue 14 is in an open state. When the door is opened, the buckle tongue 14 on the ground suction buckle tongue assembly 1 passes through the ground suction plate 23 due to the rotation of the door body, and the ground suction plate 23 is sucked up and hits the buckle tongue 14 under the suction force of the magnet 16. Continue to push the door open, the suction plate curling 232 on the ground suction plate 23 pushes the buckle tongue straight arm 144, the buckle tongue 14 rotates toward the wall and drives the Z-shaped connecting rod 17 to move from the positioning point c1224 to the positioning point d1225 in the locking mechanism 122, and the Z-shaped connecting rod 17 stops moving. Under the elastic force of the reset spring 18, the buckle tongue 14 rotates toward the door body and drives the Z-shaped connecting rod 17 to move from the positioning point d1225 to the positioning point a1222. The hook-shaped tongue 145 on the buckle tongue 14 locks the suction plate roll 232 to put the buckle tongue 14 in a locked state. Because the hook-shaped tongue 145 has a barb, the door body will not easily rotate due to wind or magnetic force. When closing the door, it is necessary to push the door body again. The door body drives the buckle tongue 14 to push the suction plate roll 232 to move toward the wall. The buckle tongue 14 drives the Z-shaped connecting rod 17 to move from the positioning point a1222 to the positioning point b1223, and the Z-shaped connecting rod 17 stops moving. Under the elastic force of the reset spring 18, the buckle tongue 14 rotates toward the wall and drives the Z-shaped connecting rod 17 to move from the positioning point b1223 to the positioning point c1224. At this time, the hook-shaped tongue 145 on the buckle tongue 14 is in an open state relative to the suction plate curl 232. Then, the door body is pulled to drive the buckle tongue 14 to separate from the suction plate 23, and the door can be closed normally.

[0048] The magnetic silent windproof floor suction of the present invention adopts a magnet suction structure combined with a mechanical locking structure to realize the function of the floor suction. The buckle tongue 14 can be closed and opened under the push of the floor suction plate 23 to switch the state, thereby solving the problem of detachment and windproof failure caused by the effect of magnetic force, and has a good fixing effect and windproof effect; at the same time, because a torsion spring is arranged inside, it can buffer the impact force when the door body is pushed open and reduce the generation of noise; and a decorative outer cover is used to make the appearance more beautiful. The present invention has a simple structure, convenient processing, and strong practicality.
