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

[0028] According to Figures 1 to 7 As shown, the quick-installation connection component of the furniture board body of the present utility model includes a connecting rod 1 fixed in the first board body 3 and an outer sleeve 2 fixed in the second board body 4. Among them, the outer sleeve 2 is provided with a first elastic mounting portion 21, a second elastic mounting portion 22, and a limiting end portion 23. The connecting rod 1 includes a connecting portion 11, a connecting head 12, and a connecting rod body 13. The connecting portion 11 is integrally connected between the connecting rod body 13 and the connecting head 12. The connecting rod body 13 is inserted into the interior of the outer sleeve 2 so that the connecting head 12 sequentially passes through the first elastic mounting portion 21 and the second elastic mounting portion 22 and is buckled between the second elastic mounting portion 22 and the limiting end portion 23. During this period, the first elastic mounting portion 21 and the second elastic mounting portion 22 are respectively touched and both expand outwards, so that the first elastic mounting portion 21 is clamped in the second board body 4, and the second elastic mounting portion 22 is tightly connected to the connecting rod body 13 and the connecting portion 11 under the action of reverse elasticity.

[0029] By the connecting head 12 of the connecting rod 1 sequentially passing through the first elastic mounting portion 21 and the second elastic mounting and being buckled between the end of the second elastic mounting portion 22 and the limiting end portion 23, the structure is simple, the connection and assembly can be quickly installed, the connection is stable and reliable, and the normal use of the product is ensured.

[0030] Referring to Figures 1 to 7 As shown, for further refinement, the first elastic mounting portion 21, the second elastic mounting portion 22, and the limiting end portion 23 are integrally formed and distributed on the outer sleeve 2 from the outside to the inside in the insertion direction of the connecting rod 1.

[0031] Moreover, the distance between the end face of the limiting end portion 23 and the second elastic mounting portion 22 is greater than or equal to the height of the connecting head 12.

[0032] Wherein, the outer sleeve 2 is further provided with a lateral positioning projection 26 assembled on the second plate body 4.

[0033] The outer sleeve 2 with such a structure is simple in structure, and under the structural action of the limiting end portion 23 and the lateral positioning projection 26, the depth of the outer sleeve 2 assembled on the second plate body 4 can be controlled, ensuring the consistency of the connection tightness between the plate bodies and improving the assembly quality of the product.

[0034] Refer to Figures 1 to 7 As shown, in further refinement, the inner diameter of the first elastic mounting portion 21 is smaller than the diameter of the connecting rod body 13. The inner diameter of the second elastic mounting portion 22 is smaller than the diameter of the connecting head 12 and greater than or equal to the diameter of the connecting portion 11.

[0035] In an optimized solution, the first elastic mounting portion 21 includes at least three first expansion pieces distributed in the middle of the outer sleeve 2 and inclined towards the center of the outer sleeve 2 respectively. The end of the first expansion piece has a first snap block 211 that is touched by the connecting rod body 13 and clamped in the second plate body 4.

[0036] And, the second elastic mounting portion 22 includes at least three second expansion pieces distributed in the middle of the outer sleeve 2 and inclined towards the center of the outer sleeve 2 respectively. The second expansion pieces are tightly connected to the connecting rod body 13 and the connecting portion 11 under the action of their rebound and closing force.

[0037] That is, during assembly, the first plate body and the second plate body are respectively pre-opened with pre-installation holes. The connecting rod 1 and the outer sleeve 2 are respectively installed in the first plate body 3 and the second plate body 4 through the pre-installation holes. Then, the connecting rod body 13 is directly inserted into the outer sleeve 2, and the connecting head 12 moves accordingly and passes between the first elastic mounting portion 21 and the second elastic mounting portion 22. At this time, due to the external thrust of the connecting rod 1, the first expansion pieces of the first elastic mounting portion 21 open outwards, prompting the first snap block 211 to be clamped in the second plate body 4, improving the biting force between the outer sleeve 2 and the second plate body and strengthening the connection stability. Subsequently, the connecting head 12 passes over the second elastic mounting portion 22. The second elastic mounting portion 22 has the characteristic of elastic closing after expansion. The second elastic mounting portion 22 is elastically closed and connected to the connecting rod body 13 and the connecting portion 11, prompting the connecting head 12 to be reversely buckled on the second expansion pieces of the second elastic mounting portion 22, realizing the fixed connection between the first plate body and the second plate body.

[0038] Thus, by adopting the structure of the first elastic mounting portion 21 and the second elastic mounting portion 22 of the present knot outer sleeve 2, the first elastic mounting portion 21 and the second elastic mounting portion 22 are oppositely arranged in reverse, so that they form an inward gripping force when expanding outwards, which can increase the biting force of the connection between the outer sleeve 2 and the plate body, improve the connection stability with the connecting rod 1, and effectively avoid the generation of debris during traditional screwing, resulting in abnormal assembly.

[0039] During this period, the outer sleeve 2 is provided with an anti-slip block 25 for preventing reverse movement from the inner hole of the second plate body 4 and coming out of the hole of the second plate body 4.

[0040] Cooperating with the structure of the anti-slip block 25 further prevents the assembly structure stability of the outer sleeve 2 and improves the use quality of the product.

[0041] In addition, the lower end of the connecting rod body 13 is provided with an expandable threaded mounting portion 14 installed in the first plate body 3. Similarly, the assembly is convenient, the connection stability between the connecting rod 1 and the first plate body is strengthened, and the structural reliability is improved.

[0042] The above specific embodiments are only the specific embodiments with better effects of the present utility model. Any structure identical or equivalent to the furniture board quick-connection assembly of the present utility model is within the protection scope of the present utility model.
