[0002] A safety buckle is a mechanical device used to secure and connect two or more objects, usually made of metal or plastic. Its main function is to ensure that the connected objects will not accidentally separate or loosen under normal or emergency conditions. The safety buckle is designed to remain stable under a certain force, but can be released under certain specific conditions (such as pressing, pulling or rotating) to facilitate user operation.

[0003] With the rapid development of science and technology, intelligent products have penetrated into all aspects of our lives. From the younger generation of students to the elderly, almost everyone may wear some intelligent electronic devices. Most of these devices are wearable, such as student cards, senior citizen cards or anti-lost devices with positioning functions. They are often hung around the user's neck for easy carrying and use. However, this convenient way of carrying hides potential safety risks. When children are playing or fighting, the lanyard is likely to be pulled by other children. Although such behavior seems harmless, it may inadvertently cause serious harm to the wearer and may even cause suffocation accidents. Therefore, in view of the above shortcomings, a lanyard safety buckle for children is proposed to solve the above problems. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figures 1 to 3 , the utility model provides an embodiment: a safety buckle for a child's lanyard, comprising a safety buckle male buckle 1, a tongue 2 is fixedly connected to the left side of the safety buckle male buckle 1, the material of the tongue 2 is acrylonitrile butadiene styrene material, the tongue 2 is designed here to adopt a plastic structure physical elasticity and the tensile force borne is less than the safety threshold of 5KG, the left side of the tongue 2 is slidably connected with a safety buckle female buckle 3, the tongue 2 is to ensure that under a certain tensile force, the safety buckle male buckle 1 and the safety buckle female buckle 3 can be separated in time, ensuring the safety of children during use, the safety buckle male buckle 1 and the safety buckle female buckle 3 are made of polycarbonate material, the polycarbonate material has excellent wear resistance and impact resistance, making the entire safety buckle more durable and extending the service life, in addition, the polycarbonate material also has good transparency and chemical stability, making the entire safety buckle more beautiful in appearance and not easily corroded by chemical substances, a card slot 4 is provided on the right side of the interior of the safety buckle female buckle 3, the design of the card slot 4 enables the tongue 2 to be smoothly connected to the safety buckle female buckle 3 to form a complete safety buckle;

[0027] Reference Figures 2 to 4The front and rear sides of the interior of the safety buckle mother buckle 3 are fixedly connected with a fixing plate 5, and the bottoms of the two fixing plates 5 are fixedly connected with a fixing shaft 6. The bottom of the fixing shaft 6 is fixedly connected to the interior of the safety buckle mother buckle 3. The outsides of the two fixing shafts 6 are rotatably connected with a rotating sleeve 7. The right sides of the two rotating sleeves 7 are fixedly connected with a toggle plate 8. The operator can control the movement of the tongue 2 by the toggle plate 8, thereby realizing the opening and closing of the safety buckle. The outside of the toggle plate 8 contacts the outside of the tongue 2. The left sides of the two toggle plates 8 are fixedly connected with a sliding plate 9. The main function of the fixing plate 5 and the fixing shaft 6 is to fix the toggle plate 8 and the sliding plate 9 to ensure their stability during movement and prevent damage caused by shaking during movement. The outside of the sliding plate 9 is rotatably connected to the interior of the safety buckle mother buckle 3. The tops of the two sliding plates 9 are provided with sliding components for sliding the sliding plates 9. The design of the sliding plate 9 allows the toggle plate 8 to slide more smoothly during movement, reducing friction and resistance during movement.

[0028] Reference Figures 3 to 5 The sliding components all include sliding rods 10, the bottoms of the two sliding rods 10 are respectively fixedly connected to the tops of the two sliding plates 9, and the tops of the two sliding rods 10 are fixedly connected with sliding disks 11. The operator can control the movement of the sliding plates 9 by sliding the sliding disks 11, thereby realizing the opening and closing of the safety buckle. The front and rear sides of the top of the safety buckle mother buckle 3 are provided with sliding grooves 12. The design of the sliding grooves 12 limits the movement range of the sliding rods 10 to prevent it from deviating from the predetermined trajectory during the movement. The outer part of the sliding rods 10 is slidably connected to the inside of the sliding grooves 12. Here, the design uses the sliding disk 11 to make the sliding plate 9 and the toggle plate 8 rotate around the fixed axis 6, so that the tongue 2 can be separated from the safety buckle mother buckle 3 with a smaller force;

[0029] Reference Figures 1 to 3 A lanyard connection assembly is provided on the far side of the safety buckle male buckle 1 and the safety buckle female buckle 3. The design of the lanyard connection assembly enables the entire safety buckle to be conveniently connected to the lanyard, which is convenient for children to carry. The two lanyard connection assemblies both include a lanyard 13. The proximal sides of the two lanyards 13 are respectively arranged on the far side of the safety buckle male buckle 1 and the safety buckle female buckle 3. The outsides of the two lanyards 13 are fixedly connected with a fixing belt 14. The design of the fixing belt 14 enables the lanyard 13 to be stably fixed on the safety buckle to prevent it from slipping during exercise.

[0030] Working principle: First, the male buckle 1 and the female buckle 3 of the safety buckle are made of polycarbonate, which has good wear resistance and impact resistance, making the entire safety buckle more durable and extending its service life. At the same time, the polycarbonate material also has good transparency and chemical stability, making the entire safety buckle more beautiful and less susceptible to chemical corrosion. Secondly, the design of the tongue 2 adopts the physical elasticity of the plastic structure, and the tensile force it can withstand is less than 5KG. This is to ensure that under a certain tensile force, the male buckle 1 and the female buckle of the safety buckle are 3 can be detached in time, ensuring the safety of children during use. Furthermore, the interior of the safety buckle mother buckle 3 is designed with a fixed plate 5 and a fixed shaft 6. The main function of these two parts is to fix the toggle plate 8 and the sliding plate 9 to ensure their stability during movement and prevent damage caused by shaking during movement. Finally, the operator can control the movement of the tongue 2 by the toggle plate 8, thereby realizing the opening and closing of the safety buckle. At the same time, the sliding plate 9 and the toggle plate 8 can use less force to realize the separation of the tongue 2 and the safety buckle mother buckle 3 during movement.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
