Embodiment 1

[0031] A capsule rotary buckle, such as Figure 1-7 As shown, it includes a male buckle 1 and a female buckle 2 that can rotate relatively. The male buckle 1 is provided with a protrusion 3, and the female buckle 2 is provided with an inner concave part 5. The protrusion 3 matches the inner concave part 5. The protrusion 3 The middle part is provided with a through hole 4 in the horizontal direction, the middle part of the inner concave part 5 is provided with a groove 6, and a spring 8 is arranged in the through hole 4, and a connector 9 is connected to both ends of the spring 8, and one end of the connector 9 is provided with a spring end The accommodating cavity 7, the other end is a columnar joint 10. The ends of the protrusions 3 are rounded.

[0032] After the male buckle and the female buckle are engaged, the columnar joint 10 of the connector 8 is stuck in the groove 6 under the action of the spring, so that the male buckle and the female buckle are closely matched an...

Abstract

The invention relates to the technical field of machining, in particular to a capsule type rotary buckle with a stable structure. The rotary buckle comprises a male buckle and a female buckle which can rotate relatively, and is characterized in that the male buckle is provided with a convex part, the female buckle is provided with an inner concave part, the convex part is matched with the inner concave part, the tail end of the convex part is provided with a through hole in the horizontal direction, a groove is formed in the middle of the inner concave part, a spring is arranged in the through hole, connecting pieces are arranged at the two ends of the spring, and the connecting pieces are just contained in the groove under the action of the spring so that the convex part can be tightly matched with the inner concave part. The spring, the connecting pieces and the groove are combined, the connecting pieces are clamped in the groove through the elastic force of the spring, the male buckle and the female buckle can rotate relatively after being clamped, the structure is simple, the occupied space is small, the tensile strength is large, loosening is not prone to occurring, performance is stable, and the application range is wider.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a capsule-type rotary buckle with stable structure. Background technique [0002] Rotating parts are very common in mechanical structures and have a wide range of uses, such as bags, key chains, pens, flashlights, etc. The current rotating part has the following structure: [0003] 1. Put one of the parts into the hole of the other part, and then riveting the part to make it larger than the hole of the other part, so as to realize the relative rotation of the two parts; [0004] 2. Put one of the parts into the hole of the other part, and then put in the retaining spring to realize the relative rotation of the two parts; [0005] 3. Put one of the parts into the other, and then put in the retaining spring to realize the relative rotation of the two parts. [0006] The first two methods take up a lot of space, have an ugly appearance, and are easy to loosen. The ...
