[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-7 The utility model provides a technical solution: a furniture rebounder, comprising a mounting seat 1, a sleeve box 2 is arranged on the top of the mounting seat 1, one end of the mounting seat 1 is fixedly connected with a cover plate 3, the other end of the mounting seat 1 is arranged with a base 9, the inner cavity of the sleeve box 2 is respectively slidably sleeved with a telescopic rod 4 and a connecting seat 11, the telescopic rod 4 passes through the surface of the cover plate 3 and extends to the outside of the sleeve box 2, and the connecting seat 11 is threadedly sleeved on one end of the telescopic rod 4, and the surface of one end of the telescopic rod 4 is symmetrically and integrally provided with a plastic extrusion The pressing end 5, one end of the telescopic rod 4 is sleeved with a steel ball 15, and the plastic extrusion end 5 is clamped at the end of the steel ball 15. When the telescopic rod 4 is retracted in the inner cavity of the sleeve 2, the cover plate 3 will be squeezed onto the plastic extrusion end 5, so that the plastic extrusion end 5 moves outward, so that the plastic extrusion end 5 is clamped at the end of the steel ball 15, so that the steel ball 15 cannot be pulled out. In the initial state, the plastic extrusion end 5 protrudes outward at one end on the surface of the telescopic rod 4, so it will be reset only when it is squeezed by the cover plate 3.

[0025] One end of the steel ball 15 is fixedly connected to a plastic screw rod 6, and a baffle 8 is fixedly sleeved on the surface of the plastic screw rod 6, and the baffle 8 abuts against one end of the telescopic rod 4, and the plastic screw rod 6 is used to limit

[0026] A sliding groove 13 is provided on the surface of the connecting seat 11, and an arc-shaped stopper 14 is fixedly connected in the middle of the sliding groove 13. A hook 10 is rotatably connected to one end of the base 9. The base 9 is fixedly installed in the inner cavity of the other end of the mounting seat 1 through a latch 7, wherein a baffle is provided at the end of the base 9. Therefore, after the base 9 is inserted into the inner cavity at the other end of the sleeve 2, it will be sealed with the port of the sleeve 2 through the baffle, and then the latch 7 is inserted from the surface of the sleeve 2 into the base 9 to fix it.

[0027] A spring 12 is arranged between the connecting seat 11 and the base 9. One end of the hook 10 is hooked on the arc-shaped stopper 14. The spring 12 is located in the inner cavity of the sleeve 2 and contacts the inner cavity of the sleeve 2. The two ends of the spring 12 are fixedly connected to the connecting seat 11 and the base 9 respectively.

[0028] When in use, firstly, the rebounder is installed on the inner wall of the cabinet door by screws through the mounting seat 1, and then the plastic screw rod 6 is threadedly sleeved on the cabinet door to align the steel ball 15 with one end of the telescopic rod 4. When the cabinet door is closed, the steel ball 15 will be inserted into one end of the telescopic rod 4, and the stopper 8 will be pressed against the end of the telescopic rod 4 to block it, so that the steel ball 15 is limited and pushes the telescopic rod 4 to slide in the inner cavity of the cover plate 3 and the sleeve box 2, and at the same time, the connecting seat 11 is also driven to slide and squeeze the spring 12. At the same time, the telescopic rod 4 is in the process of moving. The protruding plastic extrusion end 5 is squeezed by the cover plate 3, so that the plastic extrusion end 5 moves inward, thereby clamping the end of the steel ball 15, and then the hook 10 enters the sliding groove 13 and fits on the inner wall of the sliding groove 13, so that the hook 10 slides along the inner cavity of the sliding groove 13 through the squeezing of the sliding groove 13, so that the hook 10 is against the block on the sliding groove 13, and the cabinet door is released, and the elastic force of the spring 12 pushes the connecting seat 11 and the telescopic rod 4 to extend, so that the hook 10 is hooked on the arc-shaped stopper 14,

[0029] In this way, the telescopic rod 4 and the connecting seat 11 can no longer move, and the steel ball 15 is also locked, so that the cabinet door is closed;

[0030] When opening, push the cabinet door, the telescopic rod 4 and the connecting seat 11 will move, so that the hook 10 leaves the arc block 14 and is squeezed by the inclined edge of the sliding groove 13 blocking the arc block 14, so that the arc block 14 slides out along the left inner wall of the sliding groove 13 and returns to the initial state. At this time, the arc block 14 loses the fastening force, and under the elastic force of the spring 12, the telescopic rod 4 and the connecting seat 11 are driven to reset. The plastic extruded end 5 also achieves the fastening force and will automatically reset, so that the steel ball 15 is no longer clamped. Therefore, the steel ball 15 will be separated from one end of the telescopic rod 4, so that the cabinet door will be opened, and the cabinet door is directly connected to the telescopic rod 4 through the plastic screw rod 6. In this way, when closing, since the cabinet door is connected to the rebounder, there will be no gap or shaking when closing, and the closed state will be more compact.

[0031] When the cabinet door is closed, the cabinet door cannot be closed. The cabinet door is fixedly connected to the base 9 and the connecting seat 11 through the spring 12. Therefore, the plastic extrusion end 5 is directly rotated to make the plastic extrusion end 5 threadedly rotate on the connecting seat 11, so as to adjust the distance of the telescopic rod 4, thereby changing the elastic force when closing and opening the door, thereby completing the closing and opening of the door, and avoiding the phenomenon that the cabinet door cannot be closed and pops out.
