Abstract

The invention discloses a mortise structure for a solid-wood wardrobe. The mortise structure comprises a wood prism and a core plate, and is characterized in that the cross section of the wood prism is rectangular; a mortise for inserting the edge of the core plate is arranged on one side face or a plurality of side faces of the wood prism; the width of the bottom of the mortise is smaller than the width of a groove opening of the mortise; and the shape of the edge of the core plate is matched with the shape of the mortise and the core plate is inserted into the mortise. The width of the bottom of the mortise is smaller than the width of the groove opening of the mortise and the bottom of the mortise is preferably designed into an isosceles trapezoid groove, an isosceles triangle groove or an oval arc-shaped groove, so that the core plate can be more easily assembled on the corresponding wood prism, and furthermore, the relatively high connection strength of the solid-wood wardrobe is guaranteed; when the core plate has the changes of dry shrinkage and wet swelling, the friction force of a contact area between the edge of the core plate and the bottom of the mortise is small, so that the cracking of the core plate is greatly reduced, and the anti-deformation capability of the solid-wood wardrobe is enhanced.

Description

A kind of solid wood wardrobe tenon groove structure

Technical field

The invention belongs to solid wood technical field of cabinet type furniture, particularly to a kind of solid wood wardrobe tenon groove structure.

Background technology

The tongue-and-groove being used for installing central layer on current joinery and its construction solid wood wardrobe cabinet is rectangle tongue-and-groove, its installation difficulty is high, and be easy to when mounted damage tongue-and-groove or tenon, particularly when polylith central layer is installed simultaneously, difficulty is bigger, the solid wood wardrobe causing it finally to need to adopt the mode that handware connects to be fixed and full joinery and its construction cannot be realized, or pass through just can sell after professional is completed in factory；Adopt rectangle tongue-and-groove can't effectively reduce the phenomenon that central layer easily ftractures because of drying shrinkage bulking simultaneously.

Summary of the invention

The present invention seeks to as solving existing full tenon structure solid wood wardrobe and being difficult to install after sale, problem that central layer easily ftractures because of drying shrinkage bulking and propose a kind of solid wood wardrobe tenon groove structure.

The present invention solves that the problems referred to above are adopted the technical scheme that: a kind of solid wood wardrobe tenon groove structure, including wooden prism and central layer, the cross section of described wooden prism is rectangle, a side or multiple side of wooden prism are provided with the tongue-and-groove for grafting central layer edge, width bottom described tongue-and-groove closes less than the matching form of the width of tongue-and-groove notch, described central layer edge shape and tongue-and-groove and is plugged in tongue-and-groove.

Preferably, the bottom of described tongue-and-groove is isosceles trapezoid groove, and the width of described isosceles trapezoid groove becomes larger along tongue-and-groove notch direction, and the tongue-and-groove width of described isosceles trapezoid groove above section is constant and equal to the Breadth Maximum of isosceles trapezoid groove.

Preferably, the bottom of described tongue-and-groove is isosceles triangle groove, and the width of described isosceles triangle groove becomes larger along tongue-and-groove notch direction, and the tongue-and-groove width of described isosceles triangle groove above section is constant and equal to the Breadth Maximum of isosceles triangle groove.

Preferably, the bottom of described tongue-and-groove is ellipse arc groove, and the width of described ellipse arc groove becomes larger along tongue-and-groove notch direction, and the tongue-and-groove width of described ellipse arc groove above section is constant and equal to the Breadth Maximum of ellipse arc groove.

The invention have the benefit that existing full tenon groove structure solid wood wardrobe needs to be assembled by professional, otherwise very easily furniture junction is caused damage, it is installed complexity, wastes time and energy.Owing to the tongue-and-groove width of rebate of this tenon groove structure is much larger than core edges isosceles trapezoid, the thickness of isosceles triangle or front end, circular arc position, the namely thickness on top, central layer edge, this surplus can make tongue-and-groove or central layer when relatively small deformation, central layer edge top ends first drops on isosceles trapezoid groove, in isosceles triangle groove or ellipse arc groove, then along isosceles trapezoid groove, the hypotenuse of isosceles triangle groove or ellipse arc groove slips in " rectangular channel " smoothly, do not damage central layer and tongue-and-groove, install simple, time saving and energy saving, when particularly needing to install relatively polylith central layer on a solid wood wardrobe simultaneously, advantage becomes apparent from, this tenon groove structure is applied on solid wood wardrobe and just can solve the problem that full tenon structure solid wood wardrobe is difficult to install after sale.

The central layer of existing full tenon structure class furniture is often because drying shrinkage bulking ftractures easily caused by central layer.The tongue-and-groove of this tenon groove structure adopts the structure of " rectangular channel "+isosceles trapezoid groove, " rectangular channel "+isosceles triangle groove or " rectangular channel "+ellipse arc groove, when central layer shrinks, core edges isosceles trapezoid, isosceles triangle or ellipse arc position depart from advance, the contact area of central layer and tongue-and-groove is greatly reduced, make core edges force of sliding friction resistance in tongue-and-groove be greatly reduced, and then reduce degree and the probability of central layer cracking.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is further described.

The present invention includes wooden prism 1 and central layer 4, the cross section of described wooden prism 1 is rectangle, according to circumstances can be provided with the tongue-and-groove for grafting central layer 3 edge on wooden prism 1 a side or multiple side (owing to being mounted with central layer 4 in tongue-and-groove, not shown in FIG.), so that central layer 4 is more easily assembled on corresponding wooden prism 1 and ensures that connecting portion has higher bonding strength, width bottom described tongue-and-groove closes less than the matching form of the width of tongue-and-groove notch, the edge shape of described central layer 4 and tongue-and-groove and is plugged in tongue-and-groove.

Specific embodiment 1:

As it is shown in figure 1, the bottom of described tongue-and-groove is isosceles trapezoid groove 2, the width of described isosceles trapezoid groove 2 becomes larger along tongue-and-groove notch direction, and the tongue-and-groove width of described isosceles trapezoid groove 2 above section 3 is constant and equal to the Breadth Maximum of described isosceles trapezoid groove 2.

Specific embodiment 2:

As in figure 2 it is shown, the bottom of described tongue-and-groove is isosceles triangle groove 5, the width of described isosceles triangle groove 5 becomes larger along tongue-and-groove notch direction, and the tongue-and-groove width of described isosceles triangle groove 5 above section 3 is constant and equal to the Breadth Maximum of described isosceles triangle groove 5.

Specific embodiment 3:

As it is shown on figure 3, the bottom of described tongue-and-groove is ellipse arc groove 6, the width of described ellipse arc groove 6 becomes larger along tongue-and-groove notch direction, and the tongue-and-groove width of described ellipse arc groove 6 above section is constant and equal to the Breadth Maximum of described ellipse arc groove 6.
