Description
Technical field
This utility model belongs to field of furniture and in particular to a kind of concealed dovetail structure.
Background technology
Dovetail is conventional a kind of connected mode during modern furniture produces, and has easy to process, saves timber, saves into
This advantages of.Dovetail is widely used in Furniture manufacturing manufacture, and in furniture frame corner joint, casing corner engages and sheet material is spelled
The application of wide situations such as is especially extensive.But usual dovetail bonding strength is not so good as overall tenon, and this limits swallow to a certain extent
The range of application of tail tenon, and the tenon structure exposing outside have a strong impact on attractive in appearance.Accordingly, it would be desirable to improve the bond strength of dovetail
Thus strengthening the bond strength of furniture, and it is disguised, to expand its range of application to improve it.
Utility model content
This utility model is directed to deficiency of the prior art, provides a kind of concealed dovetail structure.
For achieving the above object, this utility model employs the following technical solutions：
A kind of concealed dovetail structure is it is characterised in that include：Tenon body, first connecting portion and second connecting portion；Described
Tenon body is made up of completely identical in structure first component and second component, and described first component and second component are prismatoid,
Both are integrally-formed, and wherein, area less rectangle face connects together, the larger rectangle of area facing to outside, the
One component and second component are symmetrical about center line along connecting；Described first connecting portion and second connecting portion be respectively equipped with
The mortise that first component and second component shape are adapted, described mortise has the opening of both direction；First component and second
The upper and lower surface of component is equipped with multiple shell fragments, and described shell fragment is arranged along connecting center line direction, the inclined angle with upper and lower surface
Degree setting, the incline direction of shell fragment is contrary with the direction of insertion of tenon body.
For optimizing technique scheme, the concrete measure taken also includes：
The rear surface of described first component and second component is equipped with cross recess, in tenon body insertion mortise, first component
Contact with mortise with the rear surface of second component.
Described shell fragment is symmetrical along connecting center line.
The beneficial effects of the utility model are：Processing is simple and convenient, saves material, reduces cost；Increased tenon body and tenon
The contact area of eye, makes charging capacity increase, and the design of elastic piece structure, substantially increases bond strength and anti-torsional strength；
Tenon body is wholly embedded into mortise, and concealed design improves aesthetic property.

Specific embodiment
Describe this utility model below in conjunction with the accompanying drawings in detail.
As shown in Figure 1-2, concealed dovetail structure includes tenon body 1, first connecting portion 2 and second connecting portion 3.Tenon body 1
It is made up of completely identical in structure first component 4 and second component 5, first component 4 and second component 5 are prismatoid, both
Integrally-formed, in prismatoid, area less rectangle face is connected, and the larger rectangle of area is facing to outside, the first structure
Part 4 and second component 5 along connecting line O about symmetrically, as shown in figure 3, appearing as a symmetrical butterfly from front
Knot.
First connecting portion 2 and second connecting portion 3 are respectively equipped with and first component 4 and second component 5 shape identical mortise
21st, 31, mortise 21,31 has the opening of both direction, and in first component 4 insertion mortise 21 during installation, second component 5 inserts tenon
In eye 31.
The upper and lower surface of first component 4 and second component 5 is equipped with multiple shell fragments 6, and shell fragment 6 is along connecting line O direction pair
Claim distribution, be in the setting of certain angle of inclination with upper and lower surface, the incline direction of shell fragment 6 is contrary with the direction of insertion of tenon body 1, i.e. bullet
Piece 6 tilts towards the direction away from rear surface, forms the structure similar to agnail.The process of mortise 21,31 is so inserted in tenon body 1
In, the incline direction along shell fragment 6 oppresses shell fragment 6, thus easily inserting；And will be from mortise 21,31 by external force in tenon body 1
In when extracting, due to the elastic force effect of shell fragment 6, shell fragment 6 is in close contact with mortise inwall, play unidirectional non-return effect so that
Extract very difficult, engage more firm.And consider the complexity processed, can choose whether design in mortise 21,31
The teeth groove being adapted with shell fragment 6 position.Except traditional timber, tenon body 1 also can be using new macromolecular material, such as plastics etc.,
So not only reduce cost, also simplify technique so that the installation of shell fragment is more convenient firmly.
Additionally, the rear surface of first component 4 and second component 5 is equipped with cross recess 7, when inserting mortise 21,31, first
The rear surface of component 4 and second component 5 is contacted with mortise 21,31.When tenon body 1 and mortise 21,31 cooperation, rear surface-coated has
Colloid, cross recess 7 be designed to increase after surface and mortise 21,31 contact area and charging capacity so that engaging more firm
Gu, and colloid be heated produce expand when it is also possible to provide certain expansion clearance, thus preventing tenon body 1 to be squeezed change
Shape.
During using this concealed dovetail structure, surface-coated colloid in mortise 21,31 and after tenon body 1, by the first structure
Part 4 inserts first connecting portion 2, and second component 5 inserts second connecting portion 3.The shape size of mortise 21,31 and first component 4 and
Second component 5 is adapted so that tenon body 1 is just entirely insertable in mortise 21,31, is not exposed to outside, improves fastness
While also enhance aesthetic property.
" upper and lower ", " left and right " that be related in this utility model, " in front and back " direction are relative position, not absolute position.
The above is only preferred implementation of the present utility model, protection domain of the present utility model is not limited merely to above-mentioned
Embodiment, all technical schemes belonging under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that it is right
For those skilled in the art, some improvements and modifications under the premise of without departing from this utility model principle,
Should be regarded as protection domain of the present utility model.
