Description

Buckle

technical field

The utility model provides a buckle, especially through the setting of the corresponding channel and elastic arm through the male buckle and the female buckle, so that the two need to be pushed in different directions to separate, and can be separated by the shape of the male and female buckles. Complementary design, a set of molds can be used for production, so as to achieve the effects of reliable fastening, low cost and safe use.

Background technique

Nowadays, most of the active connections between the two ropes are mainly male and female side-opening buckles. This kind of buckle is used to connect between two webbing belts, and can be applied to such as safety helmet buckles , waist belts, stroller seat belts, game console seat belts and other related purposes.

Referring to Figures 7-8, the traditional buckle mainly uses the second elastic arm A1 of the male buckle A away from the winding part A2 to push in from the channel B1 of the female buckle B away from the winding part B3, and then makes the male buckle A The central rod A4 is aligned with the guide rail (not shown in the figure) in the channel B1 of the female buckle B, so that the fastening block A3 at the end of the elastic arm A1 is snapped into the side holes B2 on both sides of the female buckle B, and the fastening The notch A31 formed by the turning surface between the block A3 and the elastic arm A1 is fastened to the edge wall B21 of the side hole B2 for positioning; when the above-mentioned male buckle A wants to disengage from the female buckle B, it is only necessary to press the buckle blocks on both sides A3, the notch A31 of the fastening block A3 can be separated from the edge wall B21 of the side hole B2, and then the male buckle A can be completely separated from the female buckle B. Its main flaws are:

Since the notch A31 on the second spring arm A1 is fastened to the edge wall B21 of the side hole B2, if the notch A31 is worn or deformed by external force for a long time, the male buckle A cannot be combined with the female buckle B , or accidents that are easy to loosen, if this side-opening buckle is used for purposes with safety considerations, it will easily lead to unpredictable dangers for users;

In addition, the male buckle A and the female buckle B buckle can be disengaged after the fastening block A3 on both sides of the male buckle A is pressed. Driven by curiosity, children with thinking ability often learn to install and disassemble the buckle by themselves. When the child is in a stroller or game machine with a seat belt, it is very easy for the child to open the buckle on the seat belt, which will lead to unexpected accidents. foreseeable danger.
