Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to a telescopic and invisible connection structure for furniture. Background Art

Among them, function is the forerunner and the driving force for the development of furniture; structure is the backbone and the basis for realizing the function; these four factors are interrelated and mutually restrictive.

[0003] The telescopic and invisible connection structure is a structure used to connect two or more boards. Its main feature is that the connection part is almost invisible during connection, having an invisible effect. This structure is usually used in furniture manufacturing, especially between boards that need to be vertically connected, and can provide a stable and beautiful connection method.

The telescopic and invisible connection structure of the furniture of the utility model is used to vertically connect two boards. The two boards include a first board and a second board. A T-shaped groove with both ends closed and having a narrow groove end and a wide groove end is opened on the board surface of the first board. The connection structure further includes: a T-shaped groove insert, an anti-disengagement part, an elastic part, and a connecting plate. The T-shaped groove insert includes an insertion part. The cross-section of the insertion part is adapted to the width of the narrow groove end of the T-shaped groove.

A locking mechanism is movably connected inside the guiding mechanism. Pressing mechanisms are symmetrically and movably connected to the front side and the rear side inside the guiding mechanism. A matching mechanism is movably connected to the upper side inside the clamping mechanism.

Pressing mechanisms 6 are symmetrically and movably connected to the front side and the rear side inside the guiding mechanism 4, which can realize the function of fixing the position of the locking mechanism 5. A matching mechanism 7 is movably connected to the upper side inside the clamping mechanism 3, which can realize the function of cooperating and connecting with the clamping mechanism 3.

[0025] For the purpose of realizing the cooperation and interconnection with the clamping mechanism 3, refer to Figure 2, the matching mechanism 7 includes a second connecting plate 71. In the middle of the lower end of the outer surface of the second connecting plate 71, a tapered block 72 is fixedly connected, which can realize the function of being connected with the clamping seat 31 in a matching manner. On the lower part of the outer surface of the tapered block 72, a second clamping groove 73 communicating with the outside is opened, which can realize the function of locking the tapered block 72 in cooperation with two clamping plates 53.

[0026] To achieve the purpose of clamping the matching mechanism 7, refer to Figure 3 , the clamping mechanism 3 includes a clamping seat 31. In the middle of the bottom wall of the inner cavity of the clamping seat 31, a through groove 32 communicating with the outside is opened, which can realize the function of facilitating the rotation of the rotating pin 51.
