[0029] In the application, in use, the slope 12 of the blocking door 11 is placed at the bottom of the door and clamped in the gap of the door bottom, the blocking seat 10 is placed in front of the blocking door 11 with a gap, and the distance monitoring block 15 is slidingly connected on the blocking door 11 and forms a clamping connection with the blocking seat 10. When an external force pushes the door, the door will press on the slope 12, and the pressure sensor 13 can sense the pressure, when the pressure exceeds a threshold value, the first alarm 14 will be triggered to sound an alarm, when the external force is large enough to push the blocking door 11, the distance monitoring block 15 and the blocking door 11 will relatively displace due to the immobility of the blocking seat 10, so that the distance monitoring block 15 slides on the blocking door 11, and the sliding distance monitoring block 15 will trigger the second alarm 16 to sound another louder and more irritating alarm, thereby playing a role of reminding and scaring off, and thereby clearly informing whether it is in a door pushing state or a state of breaking in, so as to choose different strategies according to the alarm sound. When not in use, the blocking door 11 slides into the blocking seat 10, and the distance monitoring block 15 is also hidden in the blocking seat 10, thereby playing a role of facilitating carrying.

[0030] In addition, the first alarm 14, the second alarm 16 and the pressure sensor 13 have no special requirements and can adopt commercially available products.

[0042] In the application, in use, the distance monitoring block 15 is clamped with the blocking door seat 10 through the long shaft 29. When not in use, the long shaft 29 is slid into the circular groove 30, and the distance monitoring block 15 is slid into the placing cavity 31.

[0043] The long shaft 29 is rotationally connected with the distance monitoring block 15, and the long shaft 29 penetrates the distance monitoring block 15, and the long shaft 29 is screwed with the circular groove 30.

[0044] In the application, in use, the long shaft 29 is rotated to extend out of the blocking door seat 10 with the distance monitoring block 15 through screwing, and the length of the extension is adjusted according to the distance between the blocking door seat 10 and the blocking door 11. When not in use, the long shaft 29 and the distance monitoring block 15 are extended into the blocking door seat 10 by rotating the long shaft 29.

[0045] The door stop seat 10 is further provided with a bottom surface 32, the bottom surface 32 is internally provided with a rubber suction cup 33, the door stop seat 10 is further slidably connected with a suction rod 34, one end of the suction rod 34 is fixedly connected with the rubber suction cup 33 and the other end extends out of the door stop seat 10.

[0046] In the present application, when the door stop seat 10 is placed, the rubber suction cup 33 is abutted against the ground, the suction rod 34 is pressed downward to extrude the air in the rubber suction cup 33, thereby generating negative pressure, so that the door stop seat 10 is adsorbed on the ground.

[0047] The door stop seat 10 is further provided with a camera 35, the camera 35 is connected with a WiFi module 36, the camera 35 and the WiFi module 36 are connected with the second lithium battery 27.

[0049] The inclined surface 12 and the bottom of the door stopper 11 are covered with rubber pads, and the rubber pads have stripes.

[0050] As shown in Figures 5-7 Preferably, the end of the door stopper 11 away from the door stop seat 10 is rotatably connected with a rotating plate 37, the inclined surface 12 and the pressure sensor 13 are arranged on the rotating plate 37, two through grooves 38 are arranged on the two sides of the rotating plate 37, each through groove 38 is provided with a lifting block 39, the lifting block 39 is screwed with a screw shaft 40, the two ends of the screw shaft 40 penetrate through the through groove 38 and are rotatably connected with the door stopper 11, two parallel sliding plates 42 are arranged on the two sides of the lifting block 39, the two sliding plates 42 on each side of the lifting block 39 are abutted against and slidably connected with the two end faces of the rotating plate 37, and each sliding plate 42 is rotatably connected with the lifting block 39.

[0051] In the present application, the inclination angle of the inclined surface 12 can also be adjusted according to the size of the gap between the door and the ground. When the door is pushed, the smaller the included angle between the inclined surface 12 and the ground, the greater the downward component force of the inclined surface 12, so that the friction between the door stopper 11 and the ground is greater, and it is more difficult to be pushed. During adjustment, the screw shaft 40 is rotated, and since the lifting block 39 is limited by the abutment of the plurality of sliding plates 42 and the rotating plate 37, the lifting block 39 cannot rotate, so that the lifting block 39 can move up and down, thereby rotating the rotating plate 37. During rotation, the inclination angle of the rotating plate 37 changes, and since the sliding plates 42 are rotatably connected with the lifting block 39, the sliding plates 42 can always be completely abutted against the rotating plate 37.

[0052] As shown in Figures 5-7As shown, preferably, the lower side of the rotating plate 37 has a safety plate 41 arranged in the door stopper 11, which is arranged obliquely close to the end face of the rotating plate 37.

[0054] The principle of the present application is as follows: in the placing process, the door stopper 11 is slid out of the door stopper seat 10, the inclined surface 12 of the door stopper 11 is placed at the bottom of the door and clamped in the gap of the bottom of the door, the door stopper seat 10 is placed right behind the door stopper 11 with a gap, the long shaft 29 is extended out of the door stopper seat 10 by screwing, the long shaft 29 is extended with the distance monitoring block 15, the distance monitoring block 15 is slid into the sliding groove 19, the metal strip 20 is not communicated with the metal block 21, and the length of the extension is adjusted according to the distance between the door stopper seat 10 and the door stopper 11, in the process of placing the door stopper seat 10, the rubber sucker 33 is abutted against the ground, the suction rod 34 is pressed downward to extrude the air in the rubber sucker 33, thereby generating negative pressure, and the door stopper seat 10 is adsorbed on the ground.

[0055] In use, when the door is pushed by external force, the door will press on the inclined surface 12, the pressure can be sensed by the pressure sensor 13, when the pressure exceeds the threshold value, the first alarm 14 will be triggered to generate an alarm sound, when the external force is large enough to push the door stopper 11, since the door stopper seat 10 is not moved, the relative displacement between the distance monitoring block 15 and the door stopper 11 is caused, thereby the distance monitoring block 15 is slid on the door stopper 11, the slid distance monitoring block 15 will trigger the second alarm 16 to trigger another alarm sound which is louder and more irritating, thereby playing a role of reminding and scaring off.
