Abstract

The utility model pertains to the field of furniture, and particularly relates to a desk surface folding and connecting mechanism, the technical proposal of which is that: the utility model comprises two desk surfaces spliced together and two frame edges at the bottom of the desk surfaces; a hinge is arranged at the junction of the two frame edges; a plurality of mortise-and-tenon joint structures are formed at the splicing sides of the two desk surfaces; the two slabs of the hinge, which are plane slabs, are bent downwards to form a shaft hole, and the hinge shaft ins inserted into the shaft hole; each the mortise-and-tenon joint structure is composed of a mortise and a tenon which are alternatively on the splicing sides of the two desk surfaces; the upper end of each tenon is arc-shaped with a plane bottom, and each mortise is coordinated with a tenon; the mortises and the tenons are combined as a whole with corresponding desk surfaces; the two desk surfaces are thus connected by a hinge, with mortise-and-tenon joint structures on the splicing sides; the tenon structure has excellent bearing property and the desk surfaces are excellently leveled when spread. The above structure is simply to realize, and is convenient to use and install, with a low production cost.

Description

The folding bindiny mechanism of desktop

Technical field:

The utility model belongs to field of furniture, particularly the folding bindiny mechanism of desktop.

Background technology:

The tradition folding table is spliced by two desktops, and edge all is equipped with on every desktop base, and two edge junctions respectively are equipped with circular arc and are supported, and two support obvolvent in opposite directions, and the bottom is connected through the hinge, and constitutes desktop bindiny mechanism; Two desktops rotate under the effect of bindiny mechanism, realize opening or folding purpose.Above-mentioned bindiny mechanism fastness is low, and weight capacity is poor, can't guarantee smooth after desktop launches; The desktop Mosaic face is the plane, also can't load-bearing, and the changing of the relative positions up and down can appear in two desktops under the gravity effect, uses very inconvenient.

The utility model content:

The purpose of this utility model provides the folding bindiny mechanism of the desktop that a kind of weight capacity is strong, planarization is better and cost is low.

Scheme of the present utility model is: comprise the edge on two splicing desktops and desktop bases, hinge is equipped with in two edge junctions, and the Mosaic face of two desktops is made a plurality of tenons structure that is connected.

The tenon structure that is connected is made of tenon and tongue-and-groove, and the Mosaic face of each desktop is arranged alternately tenon and tongue-and-groove at interval, and the tenon of two Mosaic faces and tongue-and-groove are corresponding one by one.Circular arc is made in the tenon upper end, and the plane is made in the bottom, and tongue-and-groove is made the cavity that cooperates with tenon.Tenon is made one with corresponding desktop.

The utility model has the advantages that: two splicing desktops connect by simple hinge, and the desktop Mosaic face is shaped on the tenon structure that is connected, and the bearing of tenon structure is good, and desktop launches more smooth.Said structure is simple, and is easy to install and use, and production cost is lower.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the installation diagram of Fig. 1.

Fig. 3 is the hinge position installation diagram of Fig. 2.

Fig. 4 is the be connected cutaway view of structure of tenon.

The specific embodiment:

With reference to Fig. 1, folding table is spliced by left and right sides desktop 1,1 ', respectively is provided with hinge 3 before and after two desktops 1,1 ' the junction, and Mosaic face is shaped on a plurality of tenons structure 4 that is connected.When depositing or transporting that two desktops 1,1 ' are folding, the desk volume reduces, and during use two desktops 1,1 ' is launched, and the desktop area increases.

With reference to Fig. 2, the front and back of left desktop 1 bottom respectively have groove 1.1, and groove 1.1 is a horizontally set, and left edge 2 is loaded in the groove 1.1 by screw 5; Right edge 2 ' also is installed on right desktop 1 ' bottom by same mode.Two edges 2,2 ' are connected by above-mentioned hinge 3, and two desktops 1,1 ' can be rotated by hinge 3.

With reference to Fig. 3, hinge 3 by about two pages of plates 3.1,3.3 and hinge axis 3.2 constitute, wherein the junction of two pages of plates 3.1,3.3 is bent to form axis hole to lower hem, hinge axis 3.2 inserts axis holes two pages of plates 3.1,3.3 is flexibly connected.Two pages of plates 3.1,3.3 are connected with edge by screw, and edge 2,2 ' drives desktop and rotates.Page or leaf plate 3.1,3.3 is plane page or leaf plate, is close to edge, and fastness is better.

With reference to Fig. 4 and Fig. 1, two desktops 1,1 ' Mosaic face are shaped on six tenons structure 4 that is connected, and the tenon structure 4 that is connected is made of tenon 4.2 and tongue-and-groove 4.1.The Mosaic face 1.2 of left side desktop 1 is arranged alternately tenon 4.2 and tongue-and-groove 4.1 at interval, Mosaic face 1 ' the .2 of right desktop 1 ' is arranged alternately tongue-and-groove 4.1 and tenon 4.2 at interval, the tenon 4.2 of two Mosaic faces and tongue-and-groove 4.1 are corresponding one by one, and tenon 4.2 is made one with desktop separately.Circular arc is made in tenon 4.2 upper ends, and the plane is made in bottom 4.3; Tongue-and-groove 4.1 is made the cavity that cooperates with tenon 4.2.Under the effect of hinge 3, left desktop 1 can clockwise rotate by right relatively desktop 1 ', shown in the middle arrow A direction of Fig. 1.In the desktop expansion process, the circular arc of tenon 4.2 outside slowly enters in the tongue-and-groove 4.1, flattens up to two desktops 1,1 ', and tenon 4.2 enters tongue-and-groove 4.1 fully.Circular arc is made in tongue-and-groove 4.1 and tenon 4.2 upper ends, and tenon 4.2 can insert tongue-and-groove 4.1 smoothly when guaranteeing the rotation of two desktops, and the bottom 4.3 of tenon 4.1 and the bottom of tongue-and-groove 4.1 are plane engagement, and weight capacity increases substantially.

Be provided with hinge 3 before and after the desktop junction, simple in structure, easy for installation, desktop is folding light.After tongue-and-groove 4.1 and tenon 4.2 cooperated, two desktops 1,1 ' horizontal level were fixed, and it is better to launch the back flatness, and desktop is not understood the changing of the relative positions up and down in the use.Be connected structure 4 of tenon increases the weight capacity of desktops; Tongue-and-groove 4.1, tenon 4.2 are made one with desktop, and one time mould molding gets final product, and production cost is lower.Above-mentioned folding table is suitable for outdoor leisure or meeting to be used, and generally adopts plastics to make, and weight is lighter, transportation, folding and store all more convenient.
