Description

Technical Field

[0001] The utility model relates to the field of clothing fasteners, in particular to a metal fastener for clothing with an inner opening and closing structure. Background Technique

[0002] With the improvement of the quality of life, traveling has gradually become one of the entertainment ways for people in their spare time. When traveling, people usually use backpacks to carry necessities such as food and clothes. When clothes, especially cotton-padded clothes, are placed in the backpack, the clothes will prop up the backpack, making the floor area of the backpack relatively large. In order to tighten the items in the backpack, generally, buckles or hook buckles are arranged on the backpack. In the industry, the hook buckle is generally also called a nine-character buckle. When in use, the two parts of the buckle are buckled together, or one end of the nine-character buckle is connected to the cloth strip on the backpack, and the other end of the nine-character buckle is hooked on the corresponding looped cloth strip on the backpack.

[0003] In the prior art (Publication No.: CN209450005U, Publication Date: October 1, 2019), a hook buckle structure for a backpack is disclosed. The base of the hook buckle structure is made of plastic or alloy material, and the base is not easy to deform. At the same time, the magnetic structures on the base and the hook fastener can provide an attractive force for the hook fastener to be buckled on the base. When in use, the buckling action of the hook fastener and the base can be easily completed, and the whole process is simple to operate and convenient to use.

[0004] However, since most of the existing nine-character buckles are of an integral structure, the situation that the belt automatically disengages from the barb easily occurs when directly hooking the belt on the barb. In the above solution, a base is added for installation. The setting of the base will increase the volume of the fastener, and at the same time, the steps of installing the belt on the base are relatively cumbersome and inconvenient to use. Therefore, it is necessary to improve the existing nine-character buckle and add a structure that does not occupy volume and can buckle the belt on the buckle. Summary of the Utility Model

[0005] The utility model overcomes the above deficiencies and provides a technical solution that can solve the above problems.

[0006] A metal fastener for clothing with an inner opening and closing structure includes a fastener body. An outer buckle is formed at the upper end of the fastener body. An inner buckle is rotatably and fittingly installed in the middle of the fastener body, and the inner buckle is located at the bottom side of the outer buckle. An elastic member is abutted and installed between the inner buckle and the fastener body. The elastic member drives the inner buckle to turn upwards, so that an "O"-shaped structure with an opening and closing is formed between the outer buckle and the inner buckle. One or more belt holes are formed at the lower end of the fastener body.

[0007] Furthermore: A thin edge is formed in the middle of the fastener body. The thickness of the thin edge is less than the thickness of the fastener body, and the inner buckle is rotatably and fittingly installed on the thin edge.

[0033] like Figure 1-6 As shown, the utility model is a metal buckle for clothing that opens and closes inwardly, comprising a buckle 1, wherein an outer buckle 2 is formed at the upper end of the buckle 1, and an inner buckle 3 is rotatably mounted on the middle part of the buckle 1, and the inner buckle 3 is located at the bottom side of the outer buckle 2; an elastic member 4 is mounted between the inner buckle 3 and the buckle 1, and the elastic member 4 drives the inner buckle 3 to flip upward, so that an open and closed "mouth"-shaped structure is formed between the outer buckle 2 and the inner buckle 3; one or more belt holes 5 are formed at the lower end of the buckle 1;

[0034] The principle is: an inner buckle 3 is installed on the inner side of the outer buckle 2, and the inner buckle 3 can be flipped upward by the elastic part 4, and form an open and closed "mouth" shaped structure with the outer buckle 2. After the strap is installed, the strap will be stuck between the outer buckle 2 and the inner buckle 3 and will not fall out by itself, so the installation is more stable. At the same time, the structure of the inner buckle 3 will not increase the volume of the entire buckle, and there is no need to equip other fixed structures to connect the strap, so it is more convenient to use. When disassembling, pushing the inner buckle 3 downward can open the "mouth" shaped structure formed by the outer buckle 2 and the inner buckle 3, which is convenient for the installation and disassembly of the strap.

[0035] Furthermore: a thin edge 6 is formed in the middle of the buckle 1, the thickness of the thin edge 6 is less than the thickness of the buckle 1, and the inner buckle 3 is rotatably mounted on the thin edge 6; this can make the buckle 1 as a whole smoother and more beautiful, and enhance the user experience.

[0036] Further: An avoidance groove 7 is formed at the right end of the upper side edge of the thin edge 6. A U-shaped slot 8 is formed on the left side of the internal buckle 3. The left end of the upper side of the thin edge 6 is installed in the U-shaped slot 8 in a clearance fit manner. The internal buckle 3 is located in the avoidance groove 7. Mounting holes 9 are formed on both the front and rear sides of the U-shaped slot 8. A hinge hole 10 is formed at the left end of the upper side of the thin edge 6. A hinge shaft 11 is installed through the hinge hole 10 and the two mounting holes 9; this makes the flipping of the internal buckle 3 more stable, and the opening and closing of the internal buckle 3 can be unobstructed by external forces.

[0037] Further: A mounting position 12 is formed on the rear side of the thin edge 6. The elastic member 4 is installed in the mounting position 12 in a clearance fit manner; the elastic member 4 is a torsion spring. The middle part of the elastic member 4 is sleeved on the hinge shaft 11. The lower end of the elastic member 4 is abutted and installed on the bottom side of the mounting position 12. The upper end of the elastic member 4 is abutted and installed in the U-shaped slot 8 of the internal buckle 3; a limiting groove 13 is formed on the bottom side of the mounting position 12. The lower end of the elastic member 4 is abutted and installed in the limiting groove 13; this makes the installation of the elastic member 4 more stable.

[0038] Further: A cut groove 14 is formed on the bottom side of the internal buckle 3. The cut groove 14 is communicated with the U-shaped slot 8. The upper end of the elastic member 4 is abutted and installed in the cut groove 14. The upper side edge of the thin edge 6 is installed in the cut groove 14 in a clearance fit manner; when the internal buckle 3 is opened, the upper side edge of the thin edge 6 can sink into the cut groove 14 on the bottom side of the internal buckle 3, thereby effectively reducing the volume of the buckle and enhancing the use experience.

[0039] Further: The external buckle 2 is in an inverted hook shape, and the internal buckle 3 is in a right angle or obtuse angle shape; this enables the external buckle 2 and the internal buckle 3 to form a "mouth" - shaped structure with an open or closed opening, which is convenient for actual use.

[0040] Further: A raised edge 15 is formed on the rear side surface of the internal buckle 3; the raised edge 15 can be used to toggle the internal buckle 3 to open it. When the internal buckle 3 is released, it can automatically reset and close through the elastic member 4, realizing the quick installation and disassembly of the belt on the buckle.

[0041] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the present utility model. Any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model all fall within the protection scope of the technical solution of the present utility model.
