Description

Improved structure of side opening buckle

technical field

The utility model relates to a side-opening buckle structure.

Background technique

Buckles are widely used nowadays, some of which are mostly male and female buckles that are used to movably wear or be fixedly connected to the movable ends of the two belts (belts, ribbons, ropes), and the two belts are separately The side end is fixed on the object, so that after the male buckle and the female buckle are docked and positioned, the purpose of adjusting the tightness of the belt body or tightening and positioning the two belt bodies is formed. The scope of use of this kind of male and female buckle It is quite extensive and can be applied to shoes, bags, clothing, backpacks, waist bags, belts, suitcases, shoulder straps, helmets, bicycle utensils (such as water bottles, tool barrels or storage boxes, etc.), safety belts (such as amusement equipment, baby Cars, etc.) or other items that need to be fixed with a belt; in addition, generally, different types of buckles have different fastening methods, and their functions are also different, and their usage will also vary.

Please refer to Fig. 6 and Fig. 7, which are three-dimensional appearance diagrams and top sectional views of the existing male and female buckles. It can be clearly seen from the figures that the existing buckle A described is mainly on both sides of the male buckle A1 Each is provided with an elastic arm A11, and a rod body A12 is arranged between the two elastic arms A11, and an opening A21 is provided at the front end of the female buckle A2, and a guide rail A22 is arranged in the opening A21, so that the elastic arm A11 of the male buckle A1 And the rod body A12 can be pushed in from the opening A21 of the female button A2, and the rod body A12 of the male button A1 is aligned with the guide rail A22 of the female button A2. After being pushed in, the fastening block A13 at the end of the elastic arm A11 can be moved The side holes A23 on both sides of the female buckle snap in, and the notch A14 formed by the turning surface between the fastening block A13 and the elastic arm A11 is buckled on the edge wall A231 of the side hole A23 to form a position.

However, when the above-mentioned existing male and female buckles are actually used, there are still many deficiencies to be improved, such as:

(1) When the male buckle A1 is pushed into the female buckle A2, the elastic arm A11 and the rod body A12 of the male buckle A1 need to face the opening A21 of the female buckle A2, because the opening A21 is just for the insertion of the elastic arm A11 and the rod body A12 , so that when the male buckle A1 is pushed into the female buckle A2, it is easy to produce a misalignment state due to misalignment, which in turn makes it inconvenient for the user to fasten, and causes the elastic arm A11 and the rod body A12 to be easily deformed and damaged due to collision.

(2) When the male buckle A1 is pushed into or away from the female buckle A2, the elastic arm A11 is used to generate elastic deformation to engage the fastening block A13 and to disengage from the side hole A23 of the female buckle A2. Straight line type, when the male buckle A1 is frequently plugged into the female buckle A2, the spring arm A11 will be deformed or broken.

Therefore, how to solve the problems and deficiencies of the existing male and female snaps is the direction that relevant manufacturers engaged in this industry are eager to study and improve.
