[0023] The following description is used to disclose the utility model so that those skilled in the art can realize the utility model. The preferred embodiments in the following description are only as examples, and other obvious variants can be thought of by those skilled in the art.

[0024] Reference Figs. 1-3As shown, a furniture assembly three-in-one connector, including a screw rod 1, a pre-embedded part 2 and an eccentric wheel 3, the upper end of the screw rod 1 is fixedly connected with a first connecting part 101, the lower end of the screw rod 1 is fixedly connected with a second connecting part 102, the outer surface of the second connecting part 102 is provided with a threaded part 103, the pre-embedded part 2 is arranged at the lower end of the screw rod 1, and the eccentric wheel 3 is movably connected to the upper end of the screw rod 1.

[0025] Among them, the pre-embedded part 2 includes a connecting seat 201, the connecting seat 201 is threadedly connected to the outer surface of the second connecting part 102 through the threaded part 103, the lower end of the connecting seat 201 is fixedly connected with two elastic connecting plates 202, the lower end of the elastic connecting plate 202 is fixedly connected with a pre-embedded threaded part 203, and the inner side of the pre-embedded threaded part 203 is fixedly connected with an inner guide block 204.

[0026] Further, the outer surface of the pre-embedded threaded part 203 is provided with a threaded connecting part, by extruding the two pre-embedded threaded parts 203 inward, then aligning with the pre-embedded hole on the plate, and rotating, the pre-embedded threaded part 203 can be embedded in the pre-embedded hole opened on the plate, and then the pre-embedded part 2 is fixed on the plate.

[0027] Further, the two pre-embedded threaded parts 203 are both outwardly inclined, the pre-embedded threaded part 203 is outwardly inclined, when installing the pre-embedded threaded part 203, by extruding the pre-embedded threaded part 203 inward, then installing it in the pre-embedded hole of the plate, after the pre-embedded threaded part 203 enters the pre-embedded hole, under the action of the elastic force of the elastic connecting plate 202, it will expand outward to apply pressure to the inner wall of the pre-embedded hole, and then the connection between the pre-embedded threaded part 203 and the pre-embedded hole is more firm, and the stability of the connection is enhanced.

[0028] Further, the inner side of the inner guide block 204 is provided with a semicircular recess for guiding the insertion of the screw rod 1, when the pre-embedded threaded part 203 is inserted into the pre-embedded hole, the two pre-embedded threaded parts 203 are extruded by the inner wall of the pre-embedded hole, so that the two inner guide blocks 204 shrink inward, and then splice into an arc-shaped through groove, the diameter of the arc-shaped through groove is the same as the diameter of the lower end of the second connecting part 102, when the second connecting part 102 is connected with the pre-embedded part 2, it can play a guiding role, when the second connecting part 102 is inserted into the inside of the arc-shaped through groove, and the screw rod 1 is rotated to connect the second connecting part 102 with the connecting seat 201, the shaking of the second connecting part 102 can be reduced.

[0029] Further, the lower end of the connecting seat 201 is fixedly connected with an outer limiting plate 205 outside the two elastic connecting plates 202, the lower end of the outer limiting plate 205 abuts against the upper end of the pre-embedded threaded part 203, the outer limiting plate 205 contacts with the pre-embedded threaded part 203, which can disperse the pressure of the connecting seat 201 acting on the elastic connecting plate 202, and then avoid the pressure concentration, which causes the elastic connecting plate 202 to break.

[0030] Further, the diameter of the second connecting part 102 at the upper end of the threaded part 103 is larger than the diameter at the lower end of the threaded part 103, and when the second connecting part 102 and the connecting seat 201 are connected, the upper end of the connecting seat 201 abuts against the part with the larger diameter at the upper end of the second connecting part 102, so that the second connecting part 102 is prevented from being inserted too far, and at the same time, because the upper end of the connecting seat 201 has a large area, the pressure borne by the screw rod 1 can be evenly dispersed, so that the three-in-one connecting piece as a whole can bear greater pressure.

[0031] Further, the outer surface of the eccentric wheel 3 is provided with a connecting groove 301, and a limiting groove 302 is provided on the outer side of the connecting groove 301, the diameter of the first connecting part 101 is the same as the width of the connecting groove 301, and the diameter of the screw rod 1 close to the first connecting part 101 is the same as the width of the limiting groove 302, by inserting the first connecting part 101 into the connecting groove 301, and then rotating the eccentric wheel 3, the first connecting part 101 can be clamped on the inner side of the limiting groove 302, and the connection between the eccentric wheel 3 and the screw rod 1 is realized.

[0032] Working principle: when assembling furniture, first, the embedded threaded part 203 is butted with the embedded hole of a plate, by extruding the two embedded threaded parts 203 inward and aligning them with the embedded hole on the plate, then, the embedded threaded part 203 is embedded into the embedded hole of the plate, because the outer surface of the embedded threaded part 203 is provided with a threaded connecting part, so a fastening connection is formed between it and the inner wall of the embedded hole, after the embedded threaded part 203 enters the embedded hole, the elastic force of the elastic connecting plate 202 will make the embedded threaded part 203 expand outward, and apply pressure to the inner wall of the embedded hole, so that the connection between the embedded threaded part 203 and the embedded hole is more fastened, and the stability of the connection is enhanced, then, the eccentric wheel 3 is pressed into the embedded hole of another plate, then, the lower end of the second connecting part 102 is inserted into the arc-shaped through groove formed by the two inner guide blocks 204, then, the screw rod 1 is rotated, and the second connecting part 102 is connected to the connecting seat 201 through the threaded part 103, after that, the first connecting part 101 is inserted into the connecting groove 301, then, the eccentric wheel 3 is rotated, so that the limiting groove 302 is clamped on one side of the first connecting part 101, and the two plates can be connected.
