[0027] The present utility model will be further described below with reference to the drawings.

[0028] According to the attached Figures 1 to 8 As shown, the easy-to-assemble furniture board body connection component of the present utility model includes a connecting rod 3 and an outer sleeve 4 for assembling and connecting the first board body 1 and the second board body 2. Among them, the first board body 1 and the second board body 2 are respectively provided with a first mounting hole 11 and a second mounting hole 21, and the connecting rod 3 is provided with an expandable threaded portion 35 adapted to be installed in the first mounting hole 11 and a connecting rod portion 31 for buckling on the outer sleeve 4. The outer sleeve 4 includes a guiding section 41 and a straight section 42 adapted to be installed in the second mounting hole 21, and the guiding section 41 and the straight section 42 are respectively provided with a guiding elastic mounting portion 44 and a straight elastic mounting portion 43. The connecting rod 3 is inserted into the straight section 42 and the guiding section 41, and the connecting rod portion 31 expands the straight elastic mounting portion 43 outwards and buckles it in the second mounting hole 21. At the same time, the guiding elastic mounting portion 44 is tightly connected to the connecting rod 3 under the action of its elastic closing force.

[0029] With the outer sleeve 4 and connecting rod 3 of the present structure, during assembly, when the connecting rod 3 is inserted into the outer sleeve 4, the connecting rod portion 31 moves and pushes the straight elastic mounting portion 43 to open outward and be mounted upside down in the second mounting hole 21. At the same time, the guiding elastic mounting portion 44 is tightly connected to the connecting rod 3 under the action of its elastic contraction force, thereby strengthening the connection stability between the outer sleeve 4 and the connecting rod 3, and increasing the bite force of the connection between the outer sleeve 4 and the second plate body 2. The structure is stable, avoiding the accumulation of debris generated during the assembly of the traditional screw-on connection set, and facilitating assembly to ensure the normal use of the product.

[0030] Reference Figures 1 to 8 As shown, in further detail, the guide section 41 is connected to the straight section 42 to form a conical outer sleeve 4 adapted to be installed in the second installation hole 21 .

[0031] Moreover, the guide section 41 of the outer sleeve 4 and the second mounting hole 21 are in transition fit; the straight section 42 of the outer sleeve 4 and the second mounting hole 21 are in interference fit.

[0032] The outer sleeve 4 of this structure is convenient for assembly, and damage to the plate body and the outer sleeve 4 due to excessive force is avoided, thereby improving the stability of the structural connection, being reliable and practical.

[0036] In practical applications, the straight section 42 of the outer sleeve 4 is provided with an anti-sliding block 45 for preventing reverse movement from the second mounting hole 21 and escaping from the second plate body 2 .

[0037] In this way, the outer sleeve 4 of this structure is adopted to further enhance the bite force between the outer sleeve 4 and the second plate body 2, and to strengthen the connection stability between the connecting rod 3 and the outer sleeve 4, thereby ensuring the use quality of the product.

[0038] It is worth noting that the straight elastic mounting portion 43 and the guide elastic mounting portion 44 of the present structure form a linear fixed structure through the two-point line principle, thereby preventing radial shaking of the outer sleeve 4 in the second mounting hole 21 and improving structural stability.

[0039] Reference Figures 1 to 8 As shown, in further detail, the connecting rod 3 includes a connecting rod portion 31, a connecting head 32, a connecting portion 33, and a mounting tail portion 34. The connecting portion 33 is integrally connected between the connecting rod portion 31 and the connecting head 32, and the mounting tail portion 34 is integrally connected to the tail end of the connecting rod portion 31. The connecting rod 3 is adapted to be inserted into the outer sleeve 4, and the connecting rod portion 31 and the connecting head 32 move accordingly and push the straight elastic mounting portion 43 and the guide elastic mounting portion 44 respectively, so that they can be buckled on the connecting head 32, and at the same time, the guide elastic mounting portion 44 is tightly connected to the connecting portion 33 under the action of its own contraction force.

[0040] Moreover, the mounting tail portion 34 is threadedly connected with an expansion thread portion 35 , and the expansion thread portion 35 is threadedly connected in the first mounting hole 11 .

[0041] The connecting rod 3 of this structure is easy to assemble, and the connection stability between the connecting rod 3 and the first plate body 1 and the outer sleeve 4 is strengthened, thereby improving the reliability and practicality of the structure.
