[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] This one-button opening and closing hook and clasp utilizes the cooperation of a pin, a locking pin, a second spring, and a push pin assembly to enable more convenient opening and closing operations. When the pin of the female hook and clasp is inserted into the locking pin, the locking pin is compressed and rises. After being inserted into place, the protrusion of the locking pin falls into the recess on the bottom surface of the pin under the action of the second spring, achieving automatic locking. Pressing the button will cause the locking pin to fall down and unlock, completing the one-button opening and closing. The operation is simple and efficient. At the same time, the elastic extension of the push pin assembly facilitates the separation of the female and male hooks. Attached Figure Description

[0026] Please see Figures 1-5 This utility model provides a technical solution: a one-button opening and closing hook, including a female hook 100 and a female hook 200. One end of the female hook 100 is connected to a pin 500, and the bottom surface of the pin 500 has a notch. One side of the female hook 200 has a pin opening 600 that matches the pin 500. The pin opening 600 has a lifting groove inside, and a locking pin 800 is slidably connected inside the lifting groove. One side of the locking pin 800 has a protrusion that matches the notch. The bottom surface of the locking pin 800 is connected to a second spring 900, and the bottom end of the second spring 900 is connected to the bottom end of the lifting groove. The female buckle 200 has round holes on both sides near the pin opening 600. The two round holes are respectively equipped with ejector pin assemblies 700. When the pin 500 of the male buckle 100 is inserted into the pin opening 600, the locking pin 800 is squeezed and rises. After being inserted into place, under the action of the second spring 900, the protrusion of the locking pin 800 falls into the bottom recess of the pin 500, realizing automatic locking. Pressing the button 400 will cause the locking pin 800 to descend and unlock, completing one-button opening and closing. The operation is simple and efficient. At the same time, the elastic extension of the ejector pin assembly 700 is conducive to the separation of the male buckle 100 and the female buckle 200.
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] As an embodiment of this utility model, the top block of the female buckle 200 has a square opening, and a button 400 is slidably connected inside the square opening. The bottom surface of the button 400 extends into the inside of the pin 600 and is connected to the top surface of the locking pin 800. The user can directly press the button 400 to drive the locking pin 800 to rise and fall, which improves the convenience of opening and closing the hook and buckle.
[0029] As an embodiment of this utility model, the ejector pin assembly 700 further includes a pin body 7001, which is slidably connected inside a circular hole. One end of the pin body 7001 is connected to a first spring 7002, and one end of the first spring 7002 is connected to one side of the inside of the circular hole. When the male buckle 100 approaches the female buckle 200, the pin body 7001 is squeezed and slides into the circular hole, and the first spring 7002 is compressed, which plays a buffering role. When the male buckle 100 is separated from the female buckle 200, the first spring 7002 will squeeze the pin body 7001, causing the ejector pin assembly 700 to extend outward and accelerate the separation action between the male buckle 100 and the female buckle 200. One end of the pin body 7001 extends to the outside of the circular hole and is connected to a hemispherical block 7003. One side of the hemispherical block 7003 contacts the outer wall of the male buckle 100, increasing the contact area with the outer wall of the male buckle 100, making the force more uniform and reducing the risk of damage to the outer wall of the male buckle 100.
[0030] As an embodiment of this utility model, the outer walls of the male buckle 100 and the female buckle 200 are respectively provided with connecting components 300. The connecting components 300 include plates 3001, and the outer walls of the male buckle 100 and the female buckle 200 are respectively connected to the plates 3001. The top surface of the plates 3001 is provided with connecting holes 3002, which can facilitate the connection of the male buckle 100 and the female buckle 200 to be installed and fixed to the items to be connected. The materials of the male buckle 100 and the female buckle 200 are both plastic, which reduces the overall weight of the connected items and is suitable for application scenarios where weight is a requirement.
[0031] As an embodiment of this utility model, the female buckle 200 has a lifting cavity inside, and the button 400 is located inside the lifting cavity, so that it provides sufficient space for the button 400 to move, which is conducive to one-button opening and closing.
[0032] Specifically, the working principle of this one-button opening and closing hook is as follows: In use, the male hook 100 and female hook 200 are installed on the item to be connected via the connecting assembly 300 on the outer wall. The plate 3001 of the connecting assembly 300 can be easily fixed using a connector through the connecting hole 3002 on the top surface. When connection is needed, the pin 500 with a notch at one end of the male hook 100 is aligned with the pin opening 600 on one side of the female hook 200 and inserted. During insertion, the locking pin 800 in the lifting groove inside the pin opening 600 is pushed upward by the pin 500, compressing the second spring 900. After the pin 500 is fully inserted, the second spring 900 rebounds, pushing the locking pin 800 downward. The protrusion on one side of the locking pin 800, which matches the notch, falls into the notch on the bottom surface of the pin 500, achieving automatic locking and completing the connection. During this process, the pin assembly 700 inside the round holes on both sides of the female buckle 200 near the pin 600 plays a role. When the male buckle 100 approaches the female buckle 200, the pin body 7001 is squeezed and slides into the round hole. The first spring 7002 connected to one end is compressed, which plays a buffering role. The hemispherical block 7003 connected to one end of the pin body 7001 contacts the outer wall of the male buckle 100, increasing the contact area, making the force even, and reducing damage to the outer wall of the male buckle 100. When separation is required, press the button 400, which is slidably connected in the square opening of the top block of the female buckle 200 and whose bottom surface is connected to the top surface of the locking pin 800. The button 400 drives the locking pin 800 to descend, causing the protrusion of the locking pin 800 to disengage from the recess of the pin 500. At the same time, the first spring 7002 rebounds, squeezing the pin body 7001 to extend outward, accelerating the separation action between the male buckle 100 and the female buckle 200.
