Description

A kind of novel separated tenon and attachment structure

Technical field

This utility model belongs to field of furniture and in particular to a kind of novel separated tenon and attachment structure.

Background technology

Split mortise is conventional a kind of connected mode during modern furniture produces, and has easy to process, saves timber, saves into This advantages of.Common Split mortise has pole tenon, ellipse tenon, triangle tenon, rectangle tenon and cheese tenon etc..Split mortise is extensively applied In Furniture manufacturing manufacture, situations such as furniture frame corner joint, casing corner joint and sheet material spell wide, application is especially extensive.But It is usual Split mortise, particularly pole tenon, bonding strength is not so good as overall tenon, and this limits the application of Split mortise to a certain extent Scope.Accordingly, it would be desirable to improve the bond strength of Split mortise thus strengthening the bond strength of furniture, expand its range of application.

Utility model content

This utility model is directed to deficiency of the prior art, provides a kind of novel separated tenon and attachment structure.

For achieving the above object, this utility model employs the following technical solutions：

, it is characterised in that including tenon body, described tenon body is equal on upper and lower, left and right and fore-and-aft direction for a kind of novel separated tenon Symmetrically, there are the waveform front and rear surfaces being formed by multiple continuous Cylinder Combinations, between two connected faces of cylinder, form edge The groove that length direction extends；Described tenon body also has flat upper and lower surface, and upper and lower surface is mounted on multiple shell fragments, described Shell fragment is in the setting of certain angle of inclination with respect to upper and lower surface, and its incline direction is contrary with the direction of insertion of tenon body.

For optimizing technique scheme, the concrete measure taken also includes：

Described shell fragment includes the first shell fragment and the second shell fragment, is symmetrically distributed in a left side half for upper and lower surface respectively along its length Side and right one side of something, described first shell fragment and the second shell fragment have contrary incline direction.

The left and right side of described tenon body is equipped with cross recess.

In addition it is also proposed that a kind of attachment structure using above-mentioned Split mortise, first connecting portion and the second connection are also included Portion, described first connecting portion and second connecting portion are equipped with the mortise being adapted with tenon body left and right side shape, described mortise Depth is the half of tenon body length.

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.

Reference is as follows：Tenon body 1, the face of cylinder 2, groove 3, shell fragment 4, the first shell fragment 41, the second shell fragment 42, cross recess 5, First connecting portion 6, second connecting portion 7, mortise 8, length L.

Specific embodiment

Describe this utility model below in conjunction with the accompanying drawings in detail.

As shown in figure 1, novel separated tenon includes tenon body 1, it is right that tenon body 1 entirety is on upper and lower, left and right and fore-and-aft direction Claim structure.Understand in conjunction with Fig. 3, tenon body 1 has and combines, by multiple continuous faces of cylinder 2, the waveform front and rear surfaces being formed, that is, before and after Surface is in wave shape, is intuitively surface texture that is placed side by side by multiple cylinders and partly overlapping and formed, and connected two Form the groove 3 extending along length L direction, the setting of this waved surface is compared to traditional pole tenon between the individual face of cylinder 2 There is higher anti-torsion effect, will not rotate in mortise, and compared to ellipse tenon etc., increased tenon body 1 and tenon again The contact area of eye, increases charging capacity, improves the bond strength of tenon body 1 and mortise.

Tenon body 1 also has flat upper and lower surface, and upper and lower surface is mounted on multiple shell fragments 4, in conjunction with Fig. 2,4 understand, bullet Piece 4 includes the first shell fragment 41 and the second shell fragment 42, upper and lower surface is equally divided into left half of and right one side of something, then the first shell fragment 41 He Second shell fragment 42 is symmetrically distributed in left half of and right one side of something along length L direction respectively.First shell fragment 41 is relative with the second shell fragment 42 It is in that certain angle of inclination is installed in upper and lower surface, its incline direction is contrary with the direction of insertion of tenon body 1, is formed similar to agnail Structure, wherein, the first shell fragment 41 and the second shell fragment 42 have contrary incline direction, and that is, the first shell fragment 41 is towards away from tenon body 1 left side The direction of side tilts, and the second shell fragment 42 tilts towards the direction away from right flank.So during tenon body 1 insertion mortise, Incline direction along shell fragment 4 oppresses shell fragment 4, thus easily inserting；And will be extracted from mortise by external force in tenon body 1 When, due to the elastic force effect of shell fragment 4, shell fragment 4 is in close contact with mortise inwall, plays unidirectional non-return effect so that extracting ten Divide difficult so that engaging more firm.In view of the complexity of processing, can choose whether design and 4, shell fragment in mortise Put the teeth groove being adapted.Except traditional timber, tenon body 1 also can be using new macromolecular material, and such as plastics etc. so not only drop Low cost, also simplify technique so that the installation of shell fragment is more convenient firmly.

Additionally, the left and right side of tenon body 1 is additionally provided with cross recess 5, when tenon body 1 and mortise cooperation, left and right side is coated with glue Body, being designed to of cross recess 5 increases contact area and the charging capacity of left and right side and mortise so that engaging more firm, and And colloid be heated produce expand when it is also possible to provide certain expansion clearance, thus preventing tenon body 1 to be squeezed deformation.

Shown in Fig. 5 is the attachment structure using novel separated tenon, and it includes first connecting portion 6 and second connecting portion 7, the One connecting portion 6 and second connecting portion 7 are equipped with the mortise 8 being adapted with tenon body 1 left and right side shape.Using this novel separated During tenon, in mortise 8 and tenon body 1 surface-coated colloid, tenon body 1 is divided into symmetrical left and right two parts, left-half has the One shell fragment 41, inserts first connecting portion 6；Right half part has the second shell fragment 42, inserts second connecting portion 7.The depth of mortise 8 is The half of tenon body 1 length, so that tenon body 1 is just entirely insertable in mortise 8, improves and also enhances U.S. while fastness The property seen.

" 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.
