Abstract
The utility model provides a stealthy connection structure of sofa crosspiece and perpendicular shelves installation, includes that the meeting department of predetermineeing of crosspiece and perpendicular shelves sets up the chamfer face of matcing, and its characterized in that still includes that the meeting piece, crosspiece and the chamfer face punishment of perpendicular shelves set up the crosspiece that a plurality of quantities are unanimous respectively and predetermine the groove and erect the shelves and predetermine the groove, the crosspiece is predetermine the groove and is predetermine the unanimous mutual correspondence of groove specification with perpendicular shelves, and connects through the connecting piece, another card income is predetermine in the groove and is erect the shelves and predetermine the groove in the groove to the connecting piece one end card. The crosspiece and the vertical crosspiece of the sofa with the oversized specification and size can be tightly connected together under the connecting action of the connecting piece, the structure is firm, the appearance is attractive, and the sofa can be easily assembled without special tools and skills in installation, so that the installation is facilitated.
Description
Technical Field
The utility model belongs to the technical field of solid wood sofa mounting structures, and particularly relates to a hidden connecting structure for mounting transverse bars and vertical bars of a sofa.
Background
When the sizes of the handrail crosspiece and the vertical crosspiece of the existing solid wood sofa are overlarge, parts need to be connected in a corner cut mode, the parts are generally connected through wood tenons or two-in-one hardware connecting pieces and connecting pieces connected in a finger joint mode, the three connecting methods are not easy to install, cannot be assembled and clamped, are not firm in structure, are large in exposed area in the using process, and the finger joint teeth can be seen on the visual surface under normal use, so that the appearance of the product is affected.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to overcome the defects of the prior art, and provide a hidden connecting structure for mounting the horizontal bars and the vertical bars of the sofa, in order to solve the technical problem, the basic concept of the technical scheme adopted by the utility model is as follows:
the utility model provides a stealthy connection structure of sofa crosspiece and perpendicular shelves installation, includes that the meeting department of predetermineeing of crosspiece and perpendicular shelves sets up the chamfer face of matcing, and its characterized in that still includes that the meeting piece, crosspiece and the chamfer face punishment of perpendicular shelves set up the crosspiece that a plurality of quantities are unanimous respectively and predetermine the groove and erect the shelves and predetermine the groove, the crosspiece is predetermine the groove and is predetermine the unanimous mutual correspondence of groove specification with perpendicular shelves, and connects through the connecting piece, another card income is predetermine in the groove and is erect the shelves and predetermine the groove in the groove to the connecting piece one end card.
The groove is predetermine to the crosspiece and erect the shelves and predetermine the groove and be trapezoidal groove, and its cross-section is trapezoidal form, the connecting piece includes two trapezoidal strip parts that the specification is unanimous, its symmetrical integrated into one piece in two parts, the connecting piece cross-section is two trapezoidal symmetrical shapes.
Compared with the prior art, the utility model has the following beneficial effects:
the crosspiece and the vertical crosspiece of the sofa with the oversized specification and size can be tightly connected together under the connecting action of the connecting piece, the structure is firm, the appearance is attractive, special tools and skills are not needed in installation, the assembly can be easily carried out, the installation is convenient, the exposed area of the connecting body can be greatly reduced due to the structure, the structure is firm, and the installation and the assembly are convenient.
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and the following embodiments are used to illustrate the present invention.
As shown in fig. 1 to 5, a stealthy connection structure of sofa crosspiece and perpendicular shelves installation, including crosspiece 1 and perpendicular shelves 2 connect the department in advance and offer the corner cut face of matcing, still include connecting piece 4, crosspiece 1 and perpendicular shelves 2 corner cut face punishment do not offer the crosspiece of a plurality of quantity unanimity and predetermine groove 31 and perpendicular shelves and predetermine groove 32, the crosspiece is predetermine groove 31 and is predetermine the groove 32 unanimous reciprocal correspondence of specification with perpendicular shelves, and connects through connecting piece 4, 4 one end card of connecting piece is gone into in the crosspiece predetermines groove 31 another card income perpendicular shelves and is predetermine in the groove 32.
Groove 31 is predetermine to crosspiece and erect shelves and predetermine groove 32 and be the dovetail groove, and its cross-section is the trapezoidal form, connecting piece 4 includes the trapezoidal strip part that two specifications are unanimous, the symmetrical integrated into one piece of its two parts, connecting piece 4 cross-section is two trapezoidal symmetrical shapes.
The utility model is realized by cutting corresponding angles of the crosspiece 1 and the vertical crosspiece 2 of the oversized sofa handrail according to the figure 1, drawing three trapezoidal grooves on the cut angle surface of the crosspiece 1 and the vertical crosspiece 2 of the sofa handrail with the cut angles, namely a crosspiece preset groove 31 and a vertical crosspiece preset groove 32 (as the figure 2), wherein the exposed surface can not be drawn through, and 20mm is reserved on the exposed surface, in addition, a double butterfly dovetail invisible connecting piece milled by a machine (as the figure 3), namely a connecting piece 4, is coated with assembly glue according to the cut angle surface of the crosspiece 1 and the vertical crosspiece 2 of the sofa handrail (as the figure 4) during assembly, the crosspiece preset groove 31, the vertical crosspiece preset groove 32 and the connecting piece 4 are coated with glue, the connecting piece 4 is placed into the crosspiece 1 and the vertical crosspiece 2 of the handrail, clamped by a clamp, when the glue is dried, the exposed part of the connecting piece 4 is removed, thus the appearance of the product is not influenced, the crosspiece and the vertical crosspiece of the sofa with the oversized specification and size can be tightly connected together under the connecting action of the connecting piece, the structure is firm, the appearance is attractive, and the sofa can be easily assembled without special tools and skills in installation, so that the installation is facilitated.
