[0025] A second sealing strip 3 is also provided inside the mounting shell 1, and the second sealing strip 3 can extend from the bottom opening of the mounting shell 1. A striker assembly 4 is provided above the second sealing strip 3, and one side of the striker assembly 4 extends from the side wall of the mounting shell 1, and the striker assembly 4 is opposite to the door frame. When the door is in a closed state, the door is opposite to the door frame, and the striker assembly 4 contacts the door frame, and the striker assembly 4 drives the second sealing strip 3 to move downward, thereby sealing the bottom gap of the door. When the door is in an open state, the door is staggered with the door frame, and the striker assembly 4 does not contact the door frame, and the striker assembly 4 drives the second sealing strip 3 to move upward and retract into the mounting shell 1.

[0026] In normal state, the striker assembly 4 located inside the mounting shell 1 works. When the door is closed, the striker assembly 4 drives the second sealing strip 3 to seal the bottom gap of the door; when the door is opened, the striker assembly 4 is reset, and the second sealing strip 3 retracts into the interior of the mounting shell 1 to facilitate the opening of the door.

[0027] In a specific state, the striker assembly 4 inside the mounting shell 1 is closed, the second sealing strip 3 is retracted into the mounting shell 1, and the gap adjustment assembly 2 works to seal the bottom gap of the door and adjust the gap opening.

[0028] The gap adjustment assembly 2 includes an adjustment ring 21 located inside the mounting shell 1, and the adjustment ring 21 is slidably connected to the mounting shell 1. A friction wheel 22 is arranged inside the adjustment ring 21, and the outer wall of the friction wheel 22 abuts against the inner wall of the adjustment ring 21, and the friction wheel 22 drives the adjustment ring 21 to rotate through friction. Two friction wheels 22 are arranged opposite to each other inside the adjustment ring 21, and the friction wheels 22 tighten the adjustment ring 21, so that the two opposite friction wheels 22 drive the adjustment ring 21 to rotate.

[0029] The positions of the two ends of the adjustment ring 21 can be adjusted respectively by two friction wheels 22 arranged opposite to each other, so that the bottom wall of the adjustment ring 21 is arranged parallel to the ground, thereby facilitating sealing of the uneven state between the bottom wall of the door and the ground through the gap adjustment component 2.

The hydraulic rod of the hydraulic cylinder 26 drives the control block to move up and down, and then the control block drives the hinge rod to rotate at its connection point, driving the friction wheel 22 to move up and down. The adjustment ring 21 is an elastic structure, so that the adjustment ring 21 can move up and down under the drive of the friction wheel 22, and the first sealing strip 23 located on the adjustment ring 21 seals the bottom end gap of the door. In some embodiments, the spacing of the adjustment ring 21 moving up and down is 2 cm.

[0035] The striker assembly 4 includes a horizontally arranged striker plate 41, the striker plate 41 includes a striker portion 411 away from the center of the mounting shell 1, and an adjustment portion 412 located inside the mounting shell 1, one end of the striker portion 411 away from the adjustment portion 412 extends from the inside of the mounting shell 1, the striker portion 411 is rotatably connected to the adjustment portion 412, and the end of the striker portion 411 close to the adjustment portion 412 is rotatably connected to the adjustment portion 412 via a rotating shaft. One end of the striker plate 4141 extends from the side wall of the mounting shell 11, and

[0036] When the striker portion 411 is in a horizontal state, one end of the striker portion 411 extending from the mounting shell 1 is used to abut against the door frame when the door is closed, and the door frame pushes the striker plate 41 to move toward a side close to the inside of the mounting shell 1 .
