DETAILED DESCRIPTION
[0021] The following will be combined with 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 of 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.
[0022] See also Figure 1-5 The utility model provides a drop-resistant and durable plastic buckle, including a female buckle 1 and a male buckle 2. Female buckle side holes 8 are provided on the left and right sides of the female buckle 1. Elastic arms 7 of male buckle plugs are provided on the left and right ends of the front side of the male buckle 2. The two female buckle side holes 8 are respectively engaged with the elastic arms 7 of the corresponding male buckle plugs. A plurality of rubber convex balls 4 are provided on the upper and lower surfaces of the female buckle 1 and the male buckle 2. A rubber arc baffle 3 is installed on the side away from the two female buckle side holes 8. A protective mechanism 9 is installed on the rear ends of the elastic arms 7 of the two male buckle plugs on the side close to each other. An anti-slip mechanism 6 is installed on the middle part of the side close to each other of the two rubber arc baffles 3.
[0023] The two protective mechanisms 9 both include a rubber block 901, and the two rubber blocks 901 are respectively installed at the rear end of the side close to the elastic arm 7 of the male buckle plug, and the two rubber blocks 901 are respectively provided with a fixed arc sleeve 903 on the side close to each other, and the rear ends of the two fixed arc sleeves 903 are respectively installed on the front side of the male buckle 2, and the inner middle ends of the two fixed arc sleeves 903 are provided with a plug rod slide groove 905, and the upper and lower ends of the two fixed arc sleeves 903 corresponding to the plug rod slide groove 905 are both provided with an upper slide groove 906, and the two upper slide grooves 906 are respectively slidably connected with the corresponding arc sliders 907, and the two plug rod slide grooves 905 are respectively slidably connected with the corresponding movable arc plug rods 904, and the rear ends of the two movable arc plug rods 904 are respectively fixedly connected with reset springs 908, and the rear ends of the two reset springs 908 are respectively installed at the rear ends of the corresponding plug rod slide grooves 905, and the front ends of the two movable arc plug rods 904 are respectively fixedly connected with the reset springs 908. It is specially installed at the middle and rear end of the inner side of the elastic arm 7 of the corresponding male buckle plug. When the elastic arms 7 of the male buckle plugs on both sides are inserted into their respective female buckle side holes 8, they need to be twisted and bent appropriately to facilitate the inward engagement of the elastic arms 7 of the male buckle plugs on both sides. In order to prevent the problem of breakage, rubber blocks 901 are added to the inner sides of the elastic arms 7 of the male buckle plugs on both sides to increase the elastic force of bending and twisting. When the elastic arms 7 of the male buckle plugs on both sides are bent and twisted, the fixed movable arc rod 904 and the upper and lower arc sliders 907 will slide backward and inward in the rod slide groove 905 and the upper slide groove 906 inside the fixed arc sleeve 903, and the reset spring 908 will rebound and reset the movable arc rod 904 on the elastic arm 7 of the male buckle plug after the elastic arm 7 of the male buckle plug is bent into the female buckle side hole 8. Therefore, the repeated operation of the elastic arm 7 of the male buckle plug engaging into the female buckle side hole 8 will not cause damage or breakage.
[0024] The two anti-slip mechanisms 6 each include a Velcro hook surface 601 and two Velcro fur surfaces 602. The two Velcro hook surfaces 601 are respectively installed at the middle of the side close to the rubber arc baffle 3, and the two Velcro fur surfaces 602 are respectively installed at the side away from the elastic arms 7 of the two male buckle plugs. After the elastic arms 7 of the male buckle plugs on both sides are inserted into their respective female buckle side holes 8, the elastic arms 7 of the male buckle plugs on both sides will contact the inner side of the rubber arc baffle 3, and at this time, the Velcro hook surfaces 601 on the elastic arms 7 of the male buckle plugs will be connected with the female buckle side holes 8. The Velcro fur veneer 602 on the rubber arc baffle 3 is glued and fixed, and the principle of gluing the Velcro hook veneer 601 and the Velcro fur veneer 602 is achieved by relying on the friction and contact area between the two fabrics. In the process of gluing the plush surface and the hook surface, the small hooks on the hook surface will entangle with the fine hairs on the plush surface to form a firm connection. This connection can withstand a certain amount of tension and shear force to ensure that the fixed object is not easy to fall off, thereby preventing the male buckle 2 from falling off when the female buckle 1 is engaged.
[0025] There are multiple air holes 902 evenly distributed on the two rubber blocks 901. If the original rubber block 901 is an integral block and the air holes 902 are added, when the elastic arm 7 of the male buckle plug is movable and twisted, the rubber block 901 is softer, the squeeze is tighter, and can have a good rebound.
[0026] Side strips 5 are installed on both the left and right sides of the male buckle 2. The addition of the side strips 5 can protect the male buckle 2 from falling and collision.
[0027] The front ends of the elastic arms 7 of the two male buckle plugs on the sides away from each other respectively press against the inner sides of the corresponding rubber arc baffles 3, and the two rubber arc baffles 3 both protrude outward. When the elastic arms 7 of the two male buckle plugs are inserted into their respective female buckle side holes 8, the rubber arc baffles 3 will be pushed outward. When the elastic arms 7 of the male buckle plugs contact the rubber arc baffles 3, the male buckle 2 will be reinforced on the female buckle 1 through the Velcro hook surface 601 and the Velcro wool surface 602, and the rubber arc baffle 3 can protect the protruding elastic arms 7 of the male buckle plug to avoid damage by external objects, thereby increasing the anti-fall design.
[0028] The two Velcro hook surfaces 601 are respectively close to or away from the two Velcro fleece surfaces 602. When the Velcro hook surfaces 601 and the Velcro fleece surfaces 602 are stuck together, they are fixed. When they are separated, the elastic arm 7 of the male buckle plug and the side hole 8 of the female buckle are separated.
[0029] In the present invention, when the elastic arms 7 of the male buckle plugs on both sides are inserted into their respective female buckle side holes 8, they need to be twisted and bent appropriately to facilitate the inward engagement of the elastic arms 7 of the male buckle plugs on both sides. In order to prevent the problem of breakage, rubber blocks 901 are added to the inner sides of the elastic arms 7 of the male buckle plugs on both sides to increase the elastic force of bending and twisting, and the movable arc plug rod 904 and the upper and lower arc sliders 907 fixed on the elastic arms 7 of the male buckle plugs on both sides will slide backward and inward in the plug rod slide groove 905 and the upper slide groove 906 inside the fixed arc sleeve 903 when the elastic arms 7 of the male buckle plug are bent and entered into the female buckle side holes 8. The reset spring 908 rebounds and resets the movable arc plug rod 904 on the elastic arm 7 of the male buckle plug. Therefore, the elastic arms 7 of the male buckle plugs on both sides of the male buckle 2 are provided with protective devices, and long-term operation in this way will not cause the elastic arms to break.
[0030] After the elastic arms 7 of the male buckle plugs on both sides are inserted into their respective female buckle side holes 8, the elastic arms 7 of the male buckle plugs on both sides will contact the inner side of the rubber arc baffle 3, and will be glued and fixed by the Velcro hook surface 601 on the elastic arms 7 of the male buckle plug and the Velcro fur surface 602 on the rubber arc baffle 3. The Velcro hook surface 601 and the Velcro fur surface 602 are glued together based on the friction and contact area between the two fabrics. In the process of gluing the plush surface and the hook surface, the small hooks on the hook surface will be entangled with the fine hair on the plush surface to form a firm connection. This connection can withstand a certain amount of tension and shear force, ensuring that the fixed object is not easy to fall off, thereby preventing the male buckle 2 from falling off when the female buckle 1 is engaged.
[0031] The addition of the side strip 5 can protect the male buckle 2 from falling and collision, and the provision of the rubber convex ball 4 can protect the female buckle 1 from falling.
[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may 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 shall be included in the protection scope of the present invention.
