Buckle

Abstract

An improved buckle includes a plastic shell, an inserting element, and a lock core. A horizontal socket fitting with the inserting element and a cylindrical mounting slot for mounting the lock core are formed on the plastic shell, the cylindrical mounting slot communicating with the horizontal socket. The horizontal socket includes a guiding block, and the inserting element includes an inserting piece for inserting into the horizontal socket to cooperate with the lock core, with two triangular notches symmetrically and a guiding groove cooperating with the guiding block formed thereon. The buckle has advantages of a simple structure and a reasonable design, and may realize the dispersion of the strength by utilizing the special structure of the lock core, so the structural strength gets ensured, and meanwhile the buckle may be kept light-weighted, and thus the buckle is suitable for the pet industry.

DETAILED DESCRIPTION OF THE INVENTION

(5) The present invention will hereinafter be described in detail with reference to an exemplary embodiment, for the purpose of further understanding the present invention.

(6) Referring to FIGS. 1-3, the buckle in an embodiment of the invention includes a plastic shell 1, an inserting element 2, and a lock core 3. A horizontal socket 4 is configured on the plastic shell 1 for fitting with the inserting element 2, and a cylindrical mounting slot 5 is configured on the shell 1 for the installation of the lock core 3. The cylindrical groove 5 is communicated with the horizontal socket 4. The horizontal socket 4 is provided with a guiding block 6, and the inserting element 2 is provided with an inserting piece 7 for inserting into the horizontal socket 4 to engage with the lock core 3, with two triangular notches 8 symmetrically formed on the inserting piece 7. The inserting piece 7 of the inserting element 2 is provided with a guiding groove 9 which cooperates with the guiding block 6. The lock core 3 includes a left spring 10, a right spring 11, a left lock block 12, and a right lock block 13, wherein the left lock block 12 is symmetrical with the right lock block 13, the left lock block 12 and the right lock block 13 are coaxially aligned with each other and interdigitating with each other. A first triangular protrusion 14 and a second triangular protrusion 15 are separately formed on front ends of the left lock block 12 and the right lock block 13. The first triangular protrusion 14 of the left lock block 12 is placed into the right lock block 13, and the second triangular protrusion 15 of the right lock block 13 is inserted into the left lock block 12. The left spring 10 is mounted in a first receiving space S1 between the front end of the right lock block 13 and left lock block 12, the right spring 11 is mounted in a second receiving space S2 between the front end of the left lock block 12 and the right lock block 13, and through the left spring 10 and the right spring 11, the coaxial displacement of the left lock block 12 and the right lock block 13 may be realized. The first triangular protrusion 14, and the second triangular protrusion 15 are separately cooperate with the triangular notches 8 of the inserting piece 7.

(7) The foregoing embodiment is only an exemplary embodiment of the present invention and is not intended to limit the present invention, and any variations or modifications of equivalents made by one skilled in the art on the base of the technical contents disclosed above without departing from the principles and contents of the technical solution of the present invention, shall also fall into the scope of the invention. It is to be understood, however, that even though numerous characteristics and advantages of the present embodiment have been set forth in the foregoing description, together with details of the structures and functions of the embodiment, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
