Description

Technical Field

[0001] The utility model relates to the technical field of rebounders, in particular to a buckle rebounder. Background Art

[0002] A door rebounder is a switch used on furniture such as cabinets and wardrobes. After the door rebounder is installed on the cabinet door and the cabinet body, there is no need to use a handle when opening and closing the cabinet door. You only need to press the cabinet door to open and close the door. Whether the cabinet door can be closed tightly depends on the connection structure of the rebounder.

[0003] In the related art, the rebounder is commonly used with a magnetic structure or an elastic plastic buckle structure. The magnetic structure is to install a magnet at the end of the rebounder, the rebounder is connected to the cabinet body, the metal sheet is connected to the cabinet door, and the metal sheet is attracted by magnetic force when the door is closed; the elastic plastic buckle is to install a U-shaped buckle on the rebounder, and a structure that cooperates with the elastic plastic buckle is installed on the cabinet door, and the cabinet door is closed by the clamping force of the elastic plastic buckle;

[0004] However, the magnetic attraction method is limited by the weight of the cabinet door and the size of the magnetic force. It is also necessary to consider that the door can be opened without deliberate force, so the magnetic force is usually not too large, which makes the cabinet door unstable after closing and may accidentally open due to insufficient magnetic force or external force stretching. At the same time, the elastic plastic buckle structure is easy to wear during the cabinet door opening and closing process. As the degree of wear of the elastic plastic buckle structure increases, its clamping force will become smaller, and the cabinet door is difficult to close tightly, which will cause the elastic plastic buckle structure to accidentally open due to insufficient holding force or external force stretching after long-term use. In view of this, we have introduced a buckle rebounder. Utility Model Content
