Description

Hidden connecting piece of furniture

Technical Field

The utility model particularly relates to a hidden connecting piece for furniture.

Background

The plate-type furniture is assembled by taking plates as a basic structure, the vertical connection between the two plates is usually formed by adopting a three-in-one connecting piece, the three-in-one connecting piece is composed of a rising bolt, a bolt and an eccentric piece, when the plate-type furniture is used, the rising bolt and the bolt are usually installed and fixed on the plate, the side surface and the front surface of the other plate are provided with holes, the bolt is inserted into the holes on the side surface, and the bolt is locked by the eccentric piece through the holes on the front surface, so that the two plates which are mutually vertical are connected.

Aiming at the technical problems, the national intellectual property office discloses a part of application number as follows: CN201520284515.9 the hidden connecting piece of the panel furniture provided by the utility model comprises a connecting pin and an expansion bolt, wherein the expansion bolt adopts a hollow structure with two open ends, the bore diameter of one end of the expansion bolt is larger than that of the other end, and the connecting pin enters the bore of the expansion bolt from one end with the larger bore diameter of the expansion bolt. The annular bulge is arranged on the outer wall of the expansion bolt to play a role in reversely locking the wood plate, and at least two expansion ports are formed at one end of the expansion bolt with a small hole diameter, so that the annular bulge is embedded into the wall of the mounting hole of the wood plate deeper, and the connection between the wood plate and the connecting piece is more firm. One of which is a connecting pin and one of which is an expansion bolt. The connecting pin is a wooden cylinder plug with the diameter of 3-6 mm. The preferred diameter is 5mm and the material of the expansion bolts is soft rubber. The expansion bolt 2 adopts a hollow structure with two open ends, the bore diameter of one end of the expansion bolt is smaller than that of the other end, and the connecting pin enters the bore of the expansion bolt from the opening at the end of the expansion bolt. Before installation, firstly, installing holes are formed in the corresponding positions of the adjacent boards, then one end of the expansion bolt with the small hole diameter is knocked into the opened installing holes, as shown in fig. 2-3, then a connecting pin is knocked into the inner holes of the expansion bolt, finally, the installing holes on the other board are aligned with the other end of the expansion bolt 2, and the end of the expansion bolt enters the installing holes by using external force, so that the two adjacent boards are tightly fixed together. In general, the connection of the connecting pin and the expansion bolt adopts interference fit, namely, the processing of the connecting pin adopts positive tolerance, and the processing size of the inner wall of the expansion bolt adopts negative tolerance, so that the connecting pin can enter the expansion bolt only by means of the action of external force and opening the expansion port, thereby ensuring that the two are tightly matched. The connection of the connecting pin to the expansion bolt 2 can also be made by means of a threaded connection.

In order to facilitate the expansion bolt to smoothly enter the mounting hole, at least more than two expansion ports are arranged at one end of the expansion bolt with small bore diameter. In order to make the connecting piece and the plate to be linked more firm, the outer walls of the two ends of the expansion bolts are respectively provided with more than one annular protrusion coaxial with the expansion bolts. The cross section of the annular protrusion is triangular, square, semicircular and tooth-shaped, and can also be in other shapes. When the expansion bolts are punched into the mounting holes on the wood plate, the annular protrusions on the expansion bolts play a role of reversely locking the wood plate; and after the connecting pin is driven into the expansion bolt, the expansion bolt can be further unfolded, so that the annular protrusion is deeply embedded into the wall of the mounting hole of the wood board, and when external force is required to pull the expansion bolt out of the hole of the wood board, the meshing resistance formed between the annular protrusion and the wood board needs to be overcome. When the installation is carried out in the whole, the installation can be carried out by matching tools, and the defect of inconvenient installation exists.
