Description

Technical Field

[0001] The present invention relates to the technical field of wooden furniture, and in particular to a fully disassembled wooden furniture splicing structure that is convenient for transportation. Background Art

[0002] Currently, wooden furniture is generally connected by bolts. Metal parts such as bolts and nuts increase material costs, and special installation tools are required for installation. Bolts and nuts are fixed to the furniture one by one, which is troublesome, time-consuming and labor-intensive. Users are also prone to mistakes when installing by themselves, and reinstalling them can cause the wood threads to slip, affecting the use effect.

[0003] Therefore, a fully disassembled wooden furniture splicing structure that is convenient for transportation is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems that the installation of existing furniture requires additional fixings and tools, which increases costs, and the installation operation is cumbersome and difficult, and errors are easy to cause damage to the wood. The present invention provides a splicing structure for fully disassembled wooden furniture that is easy to transport.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] A fully disassembled wooden furniture splicing structure that is convenient for transportation includes an insert block and a slot that are plugged and fixed to each other. The insert block has an inverted triangular cross-section, and the three corners of the inverted triangle are all arc-shaped. The rear side of the insert block is provided with an annular groove surrounding the circumference thereof, and the front outer side surface of the insert block is provided with a V-shaped groove; the shape of the slot is adapted to the insert block, and the slot has an inverted triangular cross-section, and the three corners of the inverted triangle are all arc-shaped. The inner wall of the slot is provided with a V-shaped protrusion that matches the V-shaped groove on the insert block.

[0007] Preferably, the thickness of the insert block is the same as the depth of the slot, and the maximum outer diameter of the insert block is the same as the maximum width of the slot opening.

[0008] Preferably, the edge of the end face of the plug is rounded.

[0009] Preferably, the slot opening edge is chamfered.

[0010] The beneficial effects of the present invention are as follows:

[0011] 1. The inverted triangular cross-section + dual guide design (insert block rounded corners + slot chamfered corners) enables blind insertion and alignment. The V-shaped groove / protrusion cooperates to form axial self-locking, eliminating the need for bolt tightening or tool-assisted steps, reducing assembly difficulty, assembly time, and material costs.

[0012] 2. The structure is stable. The inverted triangle cross section + arc angle structure enhances the anti-torsion ability. The V-shaped groove cooperates to achieve reliable locking, and the edge treatment improves assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Reference Figure 1-4 , a fully disassembled wooden furniture splicing structure that is easy to transport, includes a plug-in block 1 and a slot 2 that cooperate with each other to form a plug-in structure. The structural features of the plug-in block 1 are: the cross-section is an inverted triangle, and the three vertices of the inverted triangle are all transitioned with arcs to avoid stress concentration; the rear side of the plug-in block 1 (the rear end in the insertion direction) is provided with a circumferential annular groove to enhance the connection stability with the slot 2; the outer side surface of the front end of the plug-in block 1 is processed with a V-shaped groove 4 as an axial locking and positioning structure; the edge of the end face of the plug-in block 1 is chamfered to facilitate guided insertion, and the inverted triangular cross-section + double guide design (fillet of the plug-in block 1 + chamfer of the slot 2) realizes blind insertion and alignment.

[0023] Slot 2 structural features:

[0024] The cross-section is an inverted triangle that matches the plug-in block 1, and the three corners of its inner wall also use arc transitions; a V-shaped protrusion 5 is provided on the inner wall of the slot 2 at the position corresponding to the V-shaped groove 4 of the plug-in block 1, which is used to form a tight fit with the V-shaped groove 4; the opening edge of the slot 2 is chamfered to reduce insertion resistance and wear.

[0025] In a specific implementation case, during assembly, the insert 1 is inserted along the opening direction of the slot 2. The rounded corners and the chamfered corners first contact and guide the alignment. Continuing to apply thrust, the insert 1 gradually fits against the inner wall of the slot 2. The insert 1 moves downward until the V-shaped protrusion 5 is completely engaged in the V-shaped groove 4. At this time, the annular groove at the rear end of the insert 1 is just engaged with the inside of the slot 2. The V-shaped groove 4 and the V-shaped protrusion 5 on the inner wall of the slot 2 engage with each other to form a circumferential lock.
