DETAILED DESCRIPTION OF THE INVENTION

(8) Referring to FIG. 1 and FIG. 6, in the present embodiment, the easy-to-assemble buckle comprises a male buckle 1 and a female buckle assembly. The female buckle assembly comprises a female buckle 2, a fastener 3, a button 4, and a back cover 5. The female buckle 2, button 3, and back cover 5 are made of metal, such as zinc alloy. The fastener 3 is made of plastic. The button 4 is mounted inside the female buckle 2 through a fixing column 21 so that it can be pressed toward the inside of the female buckle 2. The back cover 5 and the fastener 3 are respectively assembled and fixed with the female buckle 2. The fastener 3 has a spring arm 31 on its lateral side. The button 4 is connected with the spring arm 31. The male buckle 1 has an insert pin 11. When the insert pin 11 is inserted into the female buckle assembly, the insert pin 11 is locked by the button 4 so that the male buckle 1 is coupled and fixed with the female buckle assembly. When the button 4 is pressed, the male buckle 1 can be released, so that the male buckle 1 can be pulled out. The button 4 is configured with a spring arm slot 41 with its openings facing frontward and inward. The fastener 3 is inserted from the front end of the female buckle 2 and is locked and fixed with the female buckle 2 through a buckling mechanism. The spring arm 31 is inserted into the spring arm slot 41 and is pressed against the button 4. The fastener 3 is configured with a through insert hole 32 extending from front to back. The insert pin 11 of the male buckle 1 goes through the insert hole 32 and is inserted into the female buckle 2 to be connected with the button 4.

(9) The buckling mechanism comprises a fixer 34 configured on the back side of the fastener 3 and a buckling position 51 configured on the back cover 5. After the fastener 3 is inserted into the female buckle 2, it is fixed by locking the fixer 34 with the buckling position 51.

(10) The back cover 5 is sleeved onto the fixing column 21 from the bottom of the button 4, and a spin rivet is used to fix the back cover 5 with the fixing column 21, so that the button 4 is mounted inside the female buckle 2.

(11) Two buttons 4 are provided. The two buttons 4 are separated and independent, and are respectively and symmetrically installed on the female buckle 2 through a fixing column 21, with a small part exposed on the left and right sides of the female buckle 2. Two spring arms 31 are provided to match the two buttons 4, the two spring arms 31 being symmetrically configured on the left and right sides of the fastener 3 and form an integral body with the fastener 3.

(12) The fastener 3 is configured with a guide bar 33 extending from front to back. The guide bar 33 is extended into the insert hole 32. The insert pin 11 of the male buckle 1 is configured with a guide slot on the side facing the guide bar 33. When inserting the insert pin 11 into the female buckle 2, the insertion of the insert pin 11 can be guided by inserting the guide bar 33 into the guide slot, so as to avoid unaligned insertion of the insert pin 11.

(13) During production, the two buttons 4 are firstly installed on the fixing column 21, and then the back cover 5 is also installed on the fixing column 21, so that the back cover 5 covers the button 4 on the bottom. Then, the combination of the female buckle 2, the buttons 4, and the back cover 2 undergo electroplating. After electroplating, the combination is inserted into the fastener 3 to complete the assembly of an automatically locking buckle structure, i.e., the female buckle assembly.

(14) After the male buckle 1 is inserted into the female buckle 2, it will squeeze the button 4 till it is caught inside the buckling position of the male buckle 1. Due to the elastic force of the spring arm 31, the button 4 will be caught by the buckling positions on the male buckle 1, thus forming a locking structure. To open the buckle, press the buttons 4 on both sides, and the buckling position of the button 4 will be released to release the male buckle 1. The male buckle can be detached from the female buckle assembly. When the spring arm 31 of the fastener 3 is coupled with the button 4, working with the insert pin 11 of the male buckle 1, a buckling mechanism is formed, capable of repeated pressing and releasing.

(15) The structure of the present invention is described in detail using the above preferred embodiment. However, the preferred embodiment is not intending to limit the scope of the invention. All equivalent variations or modifications based on the present patent application shall be covered by the scope of the invention.
