Description
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 locking 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 to overcome the technical defects.
In order to achieve the above object, the utility model adopts a technical scheme that a locking device of a mortise and tenon joint is provided, which comprises a first member provided with a first mortise and a second member provided with a first tenon, wherein a third member is arranged at a matching position of the first mortise of the first member and the first tenon of the second member, a lock catch is arranged at one end of the matching position of the first member and the second member of the third member, a second tenon is arranged at the other end of the matching position of the first member and the second member, a second mortise is arranged on the second member, and the second mortise is matched with the second tenon;
the thickness of the lock catch of the third component is the same as that of the first tenon, and the length of the first mortise is equal to the width of the first tenon plus the width of the lock catch;
a groove is arranged between the second mortise and the first tenon of the second component, the width and the length of the groove are matched with the thickness and the length of the third component,
the first tenon is provided with a lock catch which is the same as the lock catch on the third component, the arrangement direction of the first tenon is symmetrical to the lock catch on the third component, and the first mortise is matched with the first mortise.
Compared with the prior art, the utility model has the beneficial effects that: according to the locking device for the mortise and tenon joint, glue is not needed when the mortise and tenon joint is matched, the lock catch arranged at one end of the third component is locked with the first mortise, the second tenon arranged at the other end of the third component is matched with the second mortise arranged on the second component, and the groove arranged on the second component is matched with the third component, so that the first component and the second component cannot be loosened, the mortise and tenon joint does not depend on the glue, the service life of redwood furniture is not determined by the glue, but is determined by redwood materials, and the service life of the redwood furniture is greatly prolonged.

Detailed Description
The technical features and advantages of the present invention are described in more detail with reference to the accompanying drawings.
A mortise and tenon locking device comprises a first component 1 provided with a first mortise 9 and a second component 2 provided with a first tenon 8, wherein a third component 3 is arranged at the matching position of the first mortise 9 of the first component 1 and the first tenon 8 of the second component 2, a lock catch 7 is arranged at one end of the matching position of the first component 1 and the second component 2 of the third component 3, the other end of the third component is provided with a second tenon 6, a second mortise 5 is arranged on the second component 2, the second mortise 5 is matched with the second tenon 6, the thickness of the lock catch 7 of the third component 3 is the same as that of the first tenon 8, and the length of the first mortise 9 is equal to the width of the first tenon 8 plus the lock catch 7;
a groove 4 is arranged between a second mortise 5 and a first tenon 8 of the second component 2, the width and the length of the groove 4 are matched with the thickness and the length of the third component 3, a lock catch 7 which is the same as those on the third component 3 is arranged on the first tenon 8, the arrangement direction of the lock catch 7 is symmetrical to that of the lock catch 7 on the third component 3, and the first mortise 9 is matched with the first mortise 9, when in installation, the first tenon 8 is firstly installed in the first mortise 9, then the lock catch 7 of the third component 3 is installed in the first mortise 9, finally, the second tenon 6 at the other end of the third component 3 is knocked into the second mortise 5, thus, through the locking of the lock catch 7 arranged at one end of the third component 3 and the first mortise 9, the matching of the second tenon 6 arranged at the other end of the third component 3 and the second mortise 5 arranged on the second component 2, and the matching of the groove 4 arranged on the second component 2 and the third component 3, like this the hasp 7 of first mortise 9 and first tenon 8 and the hasp 7 of third component 3 one end all are inside big, and the outside is little, makes unable not hard up between first component 1 and the second component 2, and this locking device of tenon fourth of twelve earthly branches can be used to the both ends of table, chair, bench and the cupboard of furniture, and the third component can also be used for decorating, increases the aesthetic feeling.
