The invention relates to a buckle. Grooves are arranged on both sides of a plug. The locking device includes a limit plate, a pair of spheres and a movable lock ring. There are spherical holes on both sides of the limit plate to accommodate the ball, the movable lock ring is set outside the limit plate and moves relative to the limit plate, the inner side of the movable lock ring is provided with slots; There is a pair of elastic parts, one end of which is in contact with the movable lock ring, and the other end is in contact with the body of the female buckle; the plug enters the accommodation cavity through the opening and abuts against the limit plate, and the ball enters the groove and is supported by the movable lock ring to Secure the male and female buckles. The present invention uses the cooperation of the sphere, the groove and the movable lock ring to fix the male buckle and the female buckle, and the contact surface between the sphere and the groove is an arc surface, so that the buckle not only has a large force-bearing area and scattered force points, but also has high strength ,Safe and reliable. At the same time, the rolling friction of the ball is small, and the wear of the buckle is small when the buckle is opened and closed, which helps to prolong the service life of the buckle.
Description
technical field [0001] In particular, the present invention relates to a buckle. Background technique [0002] As a locking device, the buckle is widely used in clothing, bags, outdoor sports equipment, seat belts and other fields. The existing buckle has safety defects such as small force-bearing area, stress concentration and easy wear after the male buckle and the female buckle are fastened, resulting in the buckle not being safe and reliable and having a short service life. Therefore, prior art remains to be developed. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art, and provide a safe and reliable buckle with large stress area, less wear and tear during buckling. [0004] In order to achieve the above object, the present invention provides the following technical solutions: [0005] The present invention provides a buckle, comprising a male buckle and a female buckle, the male buckle is detach...
