The utility model provides a solid wood composite door that facilitates air flow and is provided with a ventilation device. A solid wood composite door that facilitates air flow includes a wooden door, a suction cup, a handle, a motor, and a fan blade, etc.; a suction cup is provided at the bottom end of the wooden door, a handle is installed on the wooden door, a motor is installed on the rear side above the protective cover, and the fan blade is connected to the motor. By means of suction cups arranged on the left and right sides of the bottom of the wooden door, the suction cups are adsorbed on the ground to achieve the effect of fixing the wooden door. The wooden door is directly pulled by the handle to rotate together with the suction cups. Since a motor is installed on the rear side of the wooden door above the protective cover, the motor is connected to fan blades. Starting the motor drives the fan blades to rotate, thereby accelerating the air flow in the room, achieving the effect of ventilating the room. However, when the CN220929205U technology is in operation, it is not convenient to strengthen the composite door, it is not convenient to buffer and prevent collision when the composite door is closed vigorously, and it is not convenient to soundproof the composite door. Therefore, a composite door with a reinforced structure is urgently needed. Utility Model Content

[0006] The outer wall of the first reinforced honeycomb panel is bonded with foamed polyurethane, and the inner wall of the foamed polyurethane is bonded with the second reinforced honeycomb panel.

[0007] A hydraulic sleeve is welded on one side of the door panel, a hydraulic rod is installed on the inner wall of the hydraulic sleeve, and a sealing ring is attached to the outer wall of the hydraulic rod.

[0008] Preferably, the door panel and the door frame form a rotating structure through a rotating rod, and the inner wall length of the door frame is greater than the outer wall length of the door panel.

[0009] Preferably, the outer wall of the first reinforced honeycomb panel is closely fitted with the inner wall of the foamed polyurethane, and the inner wall of the first reinforced honeycomb panel is arranged in a hexagonal structure.

[0010] Preferably, the outer wall of the foamed polyurethane is tightly fitted with the inner wall of the door panel, and the length of the outer wall of the foamed polyurethane is smaller than the length of the inner wall of the door panel.

[0011] Preferably, the hydraulic sleeve is movably connected to the hydraulic rod, and the hydraulic sleeve is symmetrically arranged with respect to the central axis of the door panel.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model connects the first reinforced honeycomb panel by arranging the door panel. When the device is used, the arrangement of the first reinforced honeycomb panel facilitates the support of the door panel, thereby increasing the strength of the door panel.

[0014] 2. The utility model provides a foamed polyurethane to closely fit the door panel. When the device is used, the foamed polyurethane fills the internal space of the door panel, thereby increasing the usability of the device.

[0015] 3. The utility model uses a hydraulic sleeve to activate the hydraulic rod. When the device is in use, the arrangement of the hydraulic sleeve and the hydraulic rod facilitates buffering and collision prevention when the door panel is closed vigorously. BRIEF DESCRIPTION OF THE DRAWINGS
