Description

An eccentric wheel assembly of a three-in-one eccentric connection

technical field

The utility model relates to the field of eccentric connectors, in particular to an eccentric wheel assembly of a three-in-one eccentric connector.

Background technique

The three-in-one cabinet connector was invented by Häfele Furniture Parts Company in the 1970s. The name "minifix" they took was registered as a patent. Later, Hettich also invented its own patented three-in-one The connecting piece is named "eccentric connecting piece", so the name "eccentric connecting piece" is used abroad. It was introduced to China in the 1980s. The three-in-one connecting piece is also called eccentric connecting piece, which is composed of eccentric wheel, connecting rod and embedded nut. .

Three-in-one connectors are generally used for vertical connection between boards during furniture assembly, replacing screws to ensure that the visible parts of the outer edge of the cabinet cannot see the screws after the connection, and a very widely used furniture assembly that is convenient for repeated disassembly and assembly. Attach hardware.

In some cases, the eccentric wheel installed on the board is also equipped with an eccentric wheel decorative cover, which is used to cover the eccentric wheel and its mounting hole on the board, so that the surface of the furniture looks smoother and more beautiful.

At present, the decorative cover of the eccentric wheel is based on the existing female screwdriver groove of the eccentric wheel, which is designed as a cross or cylindrical plunger to be inserted and fixed. In fact, almost every screwdriver female groove will appear after the screwdriver female groove is locked and installed. Deformation and distortion may even cause the plug to fall off, and the decorative cover and the outer edge of the eccentric wheel mounting hole cannot be completely fitted, which cannot achieve the ideal plugging and decorative effect;

In addition, because the diameter of the decorative cover is too large and the plug is in the central position, the outer edge of the cover is easily deformed and floated, so that the existing decorative cover is basically useless and useless in actual use.

Further, the decorative cover is further provided with a second plug, the second plug is located on the same side of the decorative cover as the first plug, and the second plug is in interference fit with the screwdriver female groove.

Further, there are multiple holes, and the first plug corresponds to the number and position of the holes.

Further, the outermost diameter of one side of the decorative cover provided with the first plug is larger than the outermost diameter of the opposite side.

Further, the outermost diameter of the decorative cover is larger than the outermost diameter of the eccentric wheel.

Further, the eccentric wheel is used to be installed in the plate, the plate is provided with an eccentric wheel installation hole, the eccentric wheel is located in the eccentric wheel installation hole, and the outermost diameter of the decorative cover is larger than that of the eccentric wheel The outermost diameter of the mounting hole.

Further, the surrounding edges of the decorative cover are rounded.

Compared with the prior art, the utility model has the following advantages:

(1) In order to overcome the disadvantages of the screwdriver female groove that is easily worn into the eccentric wheel by the plug plunger in the prior art, and the poor connection stability of the decorative cover, the eccentric wheel assembly of the utility model proposes to set a hole at one end of the eccentric wheel. One side of the cover is provided with a first plug, and the fixing of the eccentric wheel and the decorative cover is realized by connecting the first plug to the hole. The first plug and the hole are not easily damaged by wear and tear, and the first plug is closer to the decorative cover. edge, so that after the decorative cover is installed, the outer edge of the decorative cover will not be deformed and warped, so that the fixing of the decorative cover and the eccentric wheel is more durable, stable and reliable.

(2) The eccentric wheel mounting hole processed on the plate is easy to form deformation and floating, such as a jagged edge, which affects the aesthetics of the plate surface. The utility model sets the outermost diameter of the decorative cover to be larger than the outermost diameter of the eccentric wheel mounting hole. The outer diameter realizes the shielding of the edge of the eccentric wheel mounting hole and improves the aesthetics of the overall structure.
