Abstract

The utility model provides a locking device of tenon fourth of twelve earthly branches, is including the first component that is provided with first mortise and second mortise, and the second component that is provided with first tenon and the third component that is provided with the second tenon, its characterized in that, first tenon on be provided with first hasp, the second tenon on be provided with the second hasp, first hasp with second hasp phase-match, need not during the cooperation glue again, make unable not hard up between first component and second component and the third component, no longer rely on glue between the tenon fourth of twelve earthly branches, the life of padauk or wood furniture no longer is decided by glue, but by the material of padauk or wood, has prolonged the life of padauk or wood furniture greatly.

Description

Locking device of tenon fourth of twelve earthly branches

Technical Field

The utility model relates to a mortise and tenon joint of furniture, in particular to a mortise and tenon joint locking device.

Background

Along with the emphasis of the state on the traditional culture, the traditional redwood furniture is also popular among people, the traditional redwood furniture is basically spliced in a mortise and tenon structure, but for the sake of attractiveness, most of the mortises and tenons adopt half-hole straight tenons, namely the mortises are not penetrated, the tenons are relatively short, the assembly is convenient and fast, the mortises and mortises cannot crack due to too tight matching of the tenons and the mortises, the tenons have lower errors during the tenoning, the tenons are slightly smaller than the mortises, the assembly is fast, the firmness of the mortises and tenons depends on glue, the service life of general glue is only dozens of years, the service life of the redwood or high-quality solid wood is more than thousands of years, the mortise and tenon structure which does not depend on the glue becomes the key of the redwood or high-quality solid wood furniture, and a lock catch device of the mortises and mortises is provided so as to fill the defects.

In view of the above-mentioned drawbacks, the inventors of the present invention have finally obtained the present invention through a long period of research and practice.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a mortise and tenon locking device which is used for overcoming the technical defects.

In order to achieve the above object, the utility model provides a mortise and tenon locking device, which includes a first member provided with a first mortise and a second mortise, a second member provided with a first tenon, and a third member provided with a second tenon, wherein the first tenon is provided with a first lock catch, the second tenon is provided with a second lock catch, and the first lock catch is matched with the second lock catch;

the first mortise is communicated with the second mortise;

the first lock catch is a dovetail tenon, and the second lock catch is a dovetail mortise.

Compared with the prior art, the utility model has the beneficial effects that: the tenon-and-mortise locking device designed by the utility model has the advantages that the tenon heads are mutually occluded in the mortise, glue is not needed during matching, the first component, the second component and the third component cannot be loosened, the tenon-and-mortise does not depend on the glue, the service life of redwood or solid wood furniture is not determined by the glue, but by redwood or solid wood materials, and the service life of the redwood or solid wood furniture is greatly prolonged.
