Referring to fig. 1 to 10, an embodiment of a furniture rebounding device of the present invention is provided:

the utility model provides a bounce-back ware for furniture, include bobbin shell 3 and install the elastic expansion piece at 3 inner chambers of bobbin shell, elastic expansion piece's flexible end stretches out from bobbin shell 3, and elastic expansion piece includes flexible part 1, spring and trip part 2.

The hook member 2 includes a fixing head 21 fixed in the inner cavity of the cylinder case 3 and a hook 22 installed at the front end of the fixing head 21. The hook 22 includes a fixing end for fixing to the fixing head 21 and an L-shaped hook structure. One end of the telescopic component 1 facing the hook 22 is provided with a sliding groove 121, a guide block 122 is arranged in the sliding groove 121, and the top of the guide block 122 is provided with a hook position 123 for hooking the hook 22.

The spring is sleeved on the telescopic part 1, and the elastic force acts on the telescopic part 1. When the spring is in a natural state, the telescopic component 1 is ejected outwards from the barrel shell 3; the telescopic component 1 is pressed to push the telescopic component 1 into the barrel shell 3, the spring is compressed or stretched, the hook 22 slides to the hook position 123 from the sliding groove 121, and the hook 22 hooks on the hook position 123 to enable the telescopic component 1 to retract into the barrel shell 3; when the retractable member 1 is pressed again, the hook 22 is disengaged from the hook position 123 and slides out of the sliding slot 121, and the retractable member 1 is ejected outward by the elastic force of the spring.

A circle of first limiting rings which are convex are arranged on the telescopic component 1, and a circle of second limiting rings which are matched with the first limiting rings are arranged at the front end of the cylinder shell 3. When the telescopic component 1 is ejected outwards, the telescopic component 1 cannot be separated from the cylinder shell 3 through the mutual blocking of the first limiting ring and the second limiting ring.

The spout 121 includes the entry, is located the branching mouth in entry the place ahead, and guide block 122 is located the place ahead of branching mouth, and the one end of the orientation branching mouth of guide block 122 is V type end, forms the forked slide between V type end both sides wall of guide block 122 and spout 121, is respectively for getting into the slide and withdraw from the slide.

The hook 123 on the guide block 122 is V-shaped, including sliding into and out of the sloped wall. A stop 124 is arranged at the position of the sliding chute 121, which is located in front of the sliding-in inclined wall, and is used for blocking the hook 22 sliding in from the entering slideway, falling onto the sliding-in inclined wall, and being clamped to the middle of the hook position 123 along the sliding-in inclined wall; the sliding-out inclined wall is communicated with the withdrawing slideway. The slide-out inclined wall is lower than the slide-in inclined wall, so that the hook 22 can smoothly slide out of the slide-out inclined wall to the exit chute after sliding into the middle position of the hook position 123 from the slide-in inclined wall.

When the telescopic component 1 is pressed and the telescopic component 1 is pushed into the barrel shell 3, the head of the clamping hook 22 is inserted into the fork from the entrance of the sliding groove 121, slides into the sliding way from the fork, slides to the clamping hook position 123 from the sliding way, and finishes the fixation of the telescopic component 1 in a retracting way. When the telescopic part 1 is pressed again, the clamping hook 22 slides out from the sliding-out inclined wall to the withdrawing slideway, then slides out from the withdrawing slideway to the bifurcate opening, slides out from the bifurcate opening to the inlet, finally breaks away from the telescopic part 1, and the telescopic part 1 pops out outwards.
