Description

Technical Field

[0001] The utility model relates to the technical field of furniture hardware accessories, in particular to a furniture rebound device. Background Art

[0002] A rebounder is a switch used on furniture such as cabinets and drawers. After the cabinet door rebounder is installed on the cabinet door, there is no need to use a handle when opening and closing the cabinet door. The door can be opened and closed by pressing the door panel. The rebounder usually changes the end structure of the top rod and adjusts the total protrusion length of the top rod according to the type of hinge. For example, a cabinet door rebounder disclosed in patent No. CN202320893593.3. A threaded hole 31 is provided on the top rod 3, and an external thread 321 compatible with the threaded hole 31 is provided on the connecting rod 32, so that the connecting rod 32 is threadedly connected to the top rod 3, so that the total length of the top rod 3 can be adjusted, so that it can be adjusted and used according to actual needs, thereby improving the applicability of the product.

[0003] For example, when used with an ordinary hinge structure without damping, in order to ensure that the cabinet door and the cabinet body fit securely, a magnetic suction piece is usually set at the end of the rebounder top rod to ensure that the cabinet door is securely closed; however, the rapid suction and collision between the cabinet door and the rebounder often produces a loud noise and easily wears the iron sheet of the cabinet door, affecting the appearance.

[0004] For another example, with a self-resetting hinge structure, the cabinet door will automatically fit on the cabinet body. In order to avoid the noise of rapid impact, a buffer is usually set at the end of the rebounder top rod to achieve the effect of noise reduction and buffering. However, with the self-resetting hinge structure, when the cabinet door is pressed again, the cabinet door will still maintain the state of returning to the cabinet body, thereby fitting the rebounder top rod; if the length of the top rod is set too short, it is usually difficult to open the cabinet door without a handle.

[0005] Due to the limited space at the end of the push rod, the existing rebounder is usually only a structure in which either a magnetic part or a buffer part is selected. Different types of hinge structures often require different rebounders. There are many types and quantities of rebounders, and it is difficult to simultaneously accommodate multiple functional effects such as push rod length adjustment, magnetic closure, and buffering.

[0006] In addition, for example, patent number CN202320302024.7 discloses a cabinet door rebounder. If the rebounder is installed on the outside of the cabinet board, a base structure needs to be provided, and the base structure needs to be installed with an exposed bolt structure, and the coordination of the appearance is also poor.
