Detailed Implementation

[0018] like Figures 1 to 4 As shown, a furniture extension bracket includes a first mounting bracket 10, a second mounting bracket 20, and a movable bracket 30. One end of the first mounting bracket 10 has a movable mounting portion 11, and one end of the movable bracket 30 is movably connected to the movable mounting portion 11. A connecting bracket 40 is movably connected between the movable bracket 30 and the second mounting bracket 20, thus connecting the first mounting bracket 10 and the second mounting bracket 20. In use, the user pulls the movable part of the furniture, causing the second mounting bracket 20 to move away from the first mounting bracket 10 along the guide rail, thereby unfolding the movable bracket 30. At this time, the movable bracket 30 forms a stable supporting triangular structure through the connecting bracket 40, realizing the extension and stable support of the furniture structure. When the user needs to retract the furniture, they can push the furniture back to its original position, and the movable bracket 30 folds or rotates back through the movable mounting portion 11 to return to a compact form.

[0019] In practical implementation, the inner surface of the movable mounting part 11 is provided with a movable protrusion 12. One end of the movable bracket 30 is connected to the outer side of the movable protrusion 12. The two sides of the movable protrusion 12 are symmetrically recessed with movable grooves 121. The inner sides of the end of the movable bracket 30 are provided with movable sliders 31. The size of the movable groove 121 is larger than the size of the movable slider 31. The two movable sliders 31 are slidably connected in the two movable grooves 121, thereby making the movable bracket 30 and the first mounting bracket 10 movably connected. Through this structural design, not only is the movable connection between the movable bracket 30 and the first mounting bracket 10 realized, but the guiding and stability between the structures are also improved, preventing shaking and falling off. In use, the user pushes the furniture to unfold it, and the second mounting bracket 20 moves away from the first mounting bracket 10, causing the movable bracket 30 to gradually unfold from the folded state. The sliders slide and guide within the grooves, making the bracket unfold stably. During the retraction process, the movable bracket 30 is retracted to a folded state close to the first mounting bracket 10 under the constraint of the sliding groove. The structure is compact and easy to store.

[0020] In practical implementation, the inner sides of the movable mounting part 11 are evenly provided with a plurality of positioning protrusions 111, and the outer sides of the end of the movable bracket 30 are symmetrically provided with a plurality of positioning recesses 32. The positioning recesses 32 and the positioning protrusions 111 are engaged and positioned to form a stable positioning effect, preventing the bracket from shaking or misaligning during load-bearing or use. During use, as the user unfolds the furniture, the movable bracket 30 also enters the target positioning angle during sliding or rotating. The positioning protrusions 111 automatically engage with the corresponding positioning recesses 32 to achieve a locking and limiting effect. When it is necessary to retract the furniture, the user can apply appropriate force to overcome the locking connection, disengage the movable bracket 30 from its current positioning position, and slide or rotate it back to the storage position.

[0021] In practical implementation, the surface of the second mounting bracket 20 is provided with a first spring connecting buckle 21 for fixing one end of the spring, and the surface of the movable bracket 30 is provided with a second spring connecting buckle 33 for fixing the other end of the spring. A bracket spring 50 is connected between the first spring connecting buckle 21 and the second spring connecting buckle 33. In use, when the user pushes the furniture to extend or retract, the bracket spring 50 will extend or compress accordingly as the movable bracket 30 unfolds or retracts, thereby generating a rebound force. On the one hand, the spring provides auxiliary power, making it easier for the movable bracket 30 to be straightened or stably supported after unfolding; on the other hand, in the retracted state, the spring provides a closing tendency, helping the user to smoothly return the bracket to its original folded state.

[0022] In practical implementation, the surface of the movable bracket 30 is provided with a first mounting protrusion 34, on which a telescopic pump 60 is mounted and fixed by fasteners. The telescopic pump 60 has a telescopic rod 61 at its front end, which can extend or retract within the pump to provide active or passive telescopic assistance. A connecting rod sleeve 62 is connected to the front end of the telescopic rod 61. The surface of the second mounting bracket 20 is provided with a second mounting protrusion 22, and the connecting rod sleeve 62 is fitted onto the second mounting protrusion 22 and fixed by fasteners. The telescopic pump 60 is connected between the second mounting bracket 20 and the movable bracket 30. In use, the telescopic pump 60 provides thrust or damping to the movement of the bracket through the extension or retraction of the telescopic rod 61. When the user stretches or pushes back the furniture structure, the telescopic pump 60 is compressed or extended accordingly, which assists in unfolding. When the bracket is unfolded, the telescopic pump 60 provides a certain damping to control the unfolding speed, making the operation more stable and buffering the return. When the bracket is retracted, the telescopic pump controls the rebound process to prevent impact caused by instantaneous folding and provides positioning support. When the furniture is in the unfolded state, the telescopic pump is in the extended state, which can form an auxiliary support force to prevent the bracket from automatically sliding or loosening.

[0023] In practical implementation, the surface of the second mounting bracket 20 is provided with a first connecting through hole 23, the surface of the movable bracket 30 is provided with a second connecting through hole 35, one end of the connecting bracket 40 is provided with a first mounting through hole 41, and the other end of the connecting bracket 40 is provided with a second mounting through hole 42. The first mounting through hole 41 and the first connecting through hole 23 are hinged together by fasteners, and the second mounting through hole 42 and the second connecting through hole 35 are hinged together by fasteners, forming a double-ended rotatable structure. In use, when the user pushes the furniture to unfold or fold it, the second mounting bracket 20 and the movable bracket 30 move relative to each other, and the connecting bracket 40 rotates synchronously around the hinge point of the two connecting ends, thereby always maintaining a reasonable geometric support structure and improving the structural stability and linkage during the extension and retraction process.

[0024] In summary, one end of the first mounting bracket 10 is provided with a movable mounting part 11, and one end of the movable bracket 30 is movably connected to the movable mounting part 11. A connecting bracket 40 is movably connected between the movable bracket 30 and the second mounting bracket 20. The surface of the second mounting bracket 20 is provided with a first spring connecting buckle 21, and the surface of the movable bracket 30 is provided with a second spring connecting buckle 33. A bracket spring 50 is connected between the first spring connecting buckle 21 and the second spring connecting buckle 33. The surface of the movable bracket 30 is provided with a first mounting protrusion 34, and a telescopic pump 60 is mounted on the first mounting protrusion 34. The front end of the telescopic pump 60 is provided with a telescopic rod 61. The front end of the telescopic rod 61 is connected to a connecting rod sleeve 62. The surface of the second mounting bracket 20 is provided with a second mounting protrusion 22, and the connecting rod sleeve 62 is fitted onto the second mounting protrusion 22. The bracket structure for furniture telescopic extension of this utility model is stable and reliably connected. Precise guidance is achieved through the cooperation of the movable mounting part and the slider groove. At the same time, the hinge structure ensures flexible linkage between the components. The cooperation of the positioning protrusion and the positioning recess achieves multi-angle locking and positioning, improving stability and safety during use. The bracket spring provides elastic force assistance, making the telescopic operation more effortless and smooth. The telescopic pump has a buffering and damping effect, avoiding impact damage and extending service life.
