Description

TECHNICAL FIELD

[0001] The present application relates to the field of furniture hardware fittings, in particular to a furniture rebound device. BACKGROUND

[0002] The rebounder is a switch used on cabinets, drawers and other furniture. After installing the cabinet door rebounder on the cabinet door, the handle is not needed when opening and closing the cabinet door, and the door can be opened and closed by pressing the door panel. The rebounder usually changes the end structure of the top rod according to the type of hinge, and adjusts the total length of the top rod. On the market, the rebounder on the market usually sets a magnetic or buffer at the top end of the top rod, which is suitable for different hinge cabinet door structures.

[0003] However, due to the limited space at the end of the top rod, the existing rebounder usually has only a magnetic or buffer arrangement structure; different rebounders need to be configured according to different types of hinge structures, and the types and quantities of rebounder materials are more, and it is difficult to simultaneously compatible with the functions of top rod length adjustment, magnetic closing and buffer. For this reason, a furniture rebound device with buffer and magnetic closing function is designed on the market. For example, patent No. CN202410299640.0 discloses a furniture rebound device. However, the applicant found that such rebound devices still have the following defects during actual use and testing:

[0004] 1.

[0037] Referring to Figures 1 to 4 The present application provides a furniture rebound device, which comprises a base 10, a shell sleeve 20, a telescopic assembly 30 and a stroke switching structure 40.

[0038] The telescopic assembly 30 comprises a telescopic top rod 31, a telescopic shell 32, a telescopic base 33, a wire hooking body 34 and a reset elastic member 35; the telescopic shell 32 and the telescopic base 33 are in a strip shape and surround a sliding accommodation cavity in a strip shape; the telescopic top rod 31 is slidably installed in the sliding accommodation cavity and has a front end that can be telescopically moved at the front end of the telescopic shell 32 and extended; the reset elastic member 35 is installed in the sliding accommodation cavity and can keep the telescopic top rod 31 in an outward rebound or inward compression state; the shell sleeve 20 can be installed on the base 10 and press-fits the telescopic assembly 30 on the base 10.

[0040] When the wire hooking screw 42 is extended into the wire hooking short sliding groove 413, the top end of the wire hooking screw 42 can abut against the front end or the rear end of the wire hooking short sliding groove 413 to limit the sliding stroke of the telescopic top rod 31 to the front-rear stroke of the wire hooking short sliding groove 413; when the wire hooking screw 42 is not extended into the wire hooking short sliding groove 413, the wire hooking body 34 can slide in the wire hooking long sliding groove 412 to limit the sliding stroke of the telescopic top rod 31 to the front-rear stroke of the wire hooking long sliding groove 412.

[0041] In the present application, the telescopic arm is integrated into a telescopic assembly 30, which comprises the telescopic top rod 31, the telescopic shell 32 and the telescopic base 33; the telescopic shell 32 and the telescopic base 33 surround a sliding accommodation cavity in a strip shape to accommodate the telescopic top rod 31, the wire hooking body 34 and the reset elastic member 35 and other components to form a complete telescopic arm structure; then, the shell sleeve 20 is installed on the base 10 to press-fit the telescopic assembly 30 on the base 10; the telescopic assembly 30 is a split assembly, which has high stability and is not easy to have the internal reset elastic member 35 and the telescopic top rod 31 and other components come out, and is convenient and fast to install.

[0042] And the furniture rebound device further comprises a stroke switching structure 40, and the hooking wire guide rail slot 41 comprises a hooking wire ring slot 411, a hooking wire long sliding slot 412 and a hooking wire short sliding slot 413. The hooking wire ring slot 411 can be slid and hooked by the hooking wire body 34 to achieve the function of positioning and fixing in the inner pressure state of the telescopic top rod 31. When the telescopic top rod 31 is ejected, the hooking wire body 34 can slide to the end along the hooking wire long sliding slot 412 to achieve the function of long stroke positioning and fixing in the outer ejection state of the telescopic top rod 31. When the hooking wire screw 42 extends into the hooking wire short sliding slot 413, the top end of the hooking wire screw 42 can abut against the front end or the rear end of the hooking wire short sliding slot 413 to limit the sliding stroke of the telescopic top rod 31 to the front and rear strokes of the hooking wire short sliding slot 413. At this time, the telescopic top rod 31 is positioned and fixed in the short stroke state in the outer ejection state through the blocking and positioning of the hooking wire screw 42. Through the depth adjustment of the hooking wire screw 42, the long and short strokes of the telescopic top rod 31 in the outer ejection state can be switched, thereby meeting the multiple arrangement requirements of the rebounder telescopic top rod 31 in the long stroke and the short stroke.
