The cabinet doors are used very frequently in daily life. Connecting components are required between the cabinet doors and the cabinet body. Commonly used connecting components are traditional opening and closing devices such as hinges. Especially in cabinet doors that need to be flipped up, hinges cannot make the cabinet doors close slowly. The cabinet doors often hit the cabinet body and make noises. At the same time, they cannot hover, which brings inconvenience to use and affects the user's comprehensive experience. Therefore, it is necessary to invent a new flipping device to solve the existing problems. Summary of the invention

The rotary joint 3 is connected to the base sleeve 7 through the central axis 4 and can rotate freely to support the cabinet door. After the cabinet door is opened, it hovers at any angle. The linear damper 8 is used to close the cabinet door to a certain angle. The rotary joint 3 contacts the linear damper 8. Due to the reaction force of the linear damper 8, the rotary joint 3 rotates too fast. Due to this buffering damping effect, the cabinet door will be closed slowly, so that the cabinet door will not hit the cabinet body and make a sound, thereby improving the user's comprehensive experience. By rotating the adjusting bolt 6, the sleeve 7 moves forward and backward along the axial direction of the adjusting bolt 6. Because the sleeve 7 is connected to the supporting structure, the adjusting screw moves forward and backward to change the position of the gravity support point of the cabinet door by this device, so that the device can adapt to cabinet doors of different sizes and weights.
