Description

Eye-splice with locking function

Technical Field

The utility model relates to a button field, in particular to eye-splice of area locking.

Background

The button is also called as "button". In ancient romans, the original buttons were used as decorations, and the clothes were worn with decorative needles. The function of buttons in the 13 th century is the same as today. At that time, people have appreciated that the use of buttonholes on clothing has greatly increased the utility value of buttons. In the 16 th century, buttons have gained popularity. With the common use of buttons, the buttons with common button holes can not meet the increasing demands of people, and the eye-splice is gradually created, so that the eye-splice used and sold in the market at present has various types and wide purposes. Common clothing products including bags, backpacks, waist packs, baby carriers, straps, pet supplies, and special uses are commonly used. The common eye-splice generally comprises a male buckle and a female buckle, and the male buckle and the female buckle are respectively provided with a corresponding buckle mechanism to realize the buckle. Firstly, because the designed locking part is arranged at the tail end of the buckle pin, the single-point or double-point locking is realized only on the same moment, the buckle cannot bear larger pulling force and multi-angle pulling force, the moment arm is longer and slightly forceful, the deformation or the disengagement of the buckle locking part can be caused, and the reliability is poorer; secondly, due to the fact that the structure of the buckle is an opposite-insertion locking structure, the size of the buckle is large, a larger space is occupied for installing and placing the buckle body when the buckle is used, and application scenes are limited; after the buckle is locked again, the plug pins need to be pressed simultaneously during unlocking, so that the plug pins can be released by simultaneously applying force, and the operation is not quick. In conclusion, the buckle can not solve the application requirements of more complex scenes and can not completely meet the living needs of people.

Disclosure of Invention

In order to overcome the problem, the utility model provides a buckle of area locking.

The technical scheme of the utility model is that: the eye-splice with the locking function comprises a first mortise, a second mortise and a tenon, wherein concave N +1 mortise grooves are formed in the inner side of the first mortise, a first mortise fixing groove is formed in the outer side of the first mortise, and a through hole is transversely formed in the inner side of the first mortise; the inner side of the second mortise is provided with N +1 transversely protruding mortise heads, and the outer side of the second mortise is provided with a second mortise fixing groove; a through hole is transversely formed in the mortise head; the tenon is of a column shape; is divided into two sections which are both column-shaped; one section width slightly is less than another section, and the edge of one section that the width is little is provided with the tenon fixed slot, and the length of one section that the width is little is less than one section that the width is big.

A locking hole is formed in one side of the front side of the inner side of the first mortise and is positioned above the through hole, and two clamping holes are formed in the other side of the back side of the first mortise and are formed in the other side of the back side of the first mortise; a slide way is arranged between the two clamping holes.

The mortise slot corresponds to the mortise head; the number is the same; the head of the second mortise can be inserted into the mortise slot of the first mortise and connected together, and the tenon is inserted into the through hole and the through hole.

The maximum inner diameters of the through hole and the through hole correspond to the maximum outer diameter of the tenon.

One side of the wider section of the tenon is provided with N +1 mortises, each mortise is provided with a buckle and a clamping hook, and the clamping hook is in an inverted L shape; the tail end of the section with the large tenon length is provided with an anti-falling device, and the mortise at the tail end is also provided with a limit buckle which is positioned behind the clamping hook; a section of the tenon with small back width and a section with large back width are provided with a convex clamping point at a small section of the joint, and the clamping point corresponds to the clamping hole.

The first mortise, the second mortise and the tenon are all made of nylon materials.

Compared with the prior art: the utility model has the advantages that: the tensile strength is better; the connecting size of the buckle body is smaller; can be conveniently and quickly opened by one hand. Firstly, the locking part designed by the utility model realizes transverse connection in the middle of the buckle, can realize N +1 multipoint locking, can bear larger transverse tension and inclination tension, has shorter arm of force, is not easy to deform or lock and release, and has good tensile capacity and reliability; secondly, as the structure of the utility model adopts the opposite insertion buckling and the middle shaft core-penetrating locking structure, the volume of the insertion buckle is obviously reduced, and only a small space is needed for installing and placing the buckle body in use, so that the application scene is wider; the utility model discloses a once more after the buckle locking, only need carry the tenon body during the unblock, can let both sides fourth of the twelve earthly branches head, fourth of the twelve earthly branches groove (or fourth of the twelve earthly branches body) come off, convenient and fast can one-hand operation. To sum up, this utility model has solved technical problem such as traditional eye-splice easy unblock, intensity difference, bulky, difficult operation under the prior art, provides more choices for the application demand of more complicated scenes, can satisfy people to high strength, quick-opening, easy-to-use eye-splice needs.
