Figure 2 , showing Figure 1 The exploded structure diagram of the structure shown is shown below. Figure 1 and Figure 2 , the utility model of the pendant head push-type elastic switch buckle is described.
[0036] like Figure 1 and Figure 2 As shown, the pendant head push-type elastic switch buckle of the utility model includes a lock hook 21 and a lock tongue 22. The lock hook 21 is connected to the pendant head. An opening 211 is formed on one side of the lock hook 21. The setting of the opening 211 allows the interior of the lock hook 21 to communicate with the outside world; the lock tongue 22 is arranged at the opening 211 of the lock hook 21. The lock tongue 22 has a first end 221 and a second end 222 arranged opposite to each other. The first end 221 of the lock tongue 22 is hingedly connected to the lock hook 21. Figure 3 and Figure 4 As shown, the second end 222 of the locking tongue 22 can rotate around the hinge toward the inside of the locking hook 21 to open the opening 211 or rotate around the hinge toward the outside of the locking hook 21 to abut against the corresponding part of the locking hook 21 to close the opening 211 .
[0037] In this way, the opening 211 and the closing of the opening 211 can be realized by rotating the lock tongue 22, that is, the opening and closing of the switch buckle can be realized, and the installation and removal of the pendant head connected to the switch buckle can be easily completed, making the installation and removal of the pendant head simple and convenient. The rotation of the lock tongue 22 is realized by pressing or pushing the lock tongue, and the operation is convenient. The switch buckle of the utility model provides a simple connection method for the pendant head, so that the pendant head can be adjusted at will according to the needs, providing a large design space for designers and users.
[0038] In a specific embodiment of the present invention, Figure 2 and Figure 4 As shown, the portion of the lock hook 21 corresponding to the second end 222 of the lock tongue 22 is provided with an arc-shaped resisting portion 212, and the setting height of the side of the resisting portion 212 close to the inside of the lock hook 21 is higher than the setting height of the side of the resisting portion 212 close to the outside of the lock hook 21; the second end 222 of the lock tongue 22 is formed with an abutting end face 223 adapted to the resisting portion 212.
[0039] The blocking portion 212 is in contact with the abutting end surface 223 , so that the locking tongue 22 can be restricted from further rotating toward the outside of the locking hook 21 .
[0040] Preferably, the blocking portion 212 and the abutting end surface 223 are arc surfaces or inclined surfaces.
[0041] In a specific embodiment of the present invention, Figure 2 and Figure 5 As shown, the first end 221 of the lock tongue 22 is hingedly connected to the lock hook 21 through a pin shaft 23, and a torsion spring 24 is sleeved on the pin shaft 23, one end of the torsion spring 24 is connected to the lock hook 21, and the other end of the torsion spring 24 is connected to the lock tongue 22, and the torsion spring 24 applies elastic force to the lock tongue 22 to allow the lock tongue 24 to rotate around the hinge toward the outside of the lock hook 21.
[0042] In this way, the torsion spring 24 applies elastic force to the lock tongue 22 in the direction of closing the switch buckle, so that the abutting end surface 223 of the lock tongue 22 is always in contact with the blocking portion 212, achieving a firm, stable and reliable closing effect, improving the firmness and stability of the pendant head connection, and avoiding the pendant head from accidentally falling off.
[0043] Furthermore, a first embedding groove 224 is provided at the first end 221 of the lock tongue 22, and a second embedding groove 214 is provided at the corresponding position of the lock hook 21. The first end 221 of the lock tongue 22 is partially placed in the second embedding groove 214, and then rotatably connected to the groove wall corresponding to the second embedding groove 214 of the lock hook 21 through the pin shaft 23. The lock tongue 22 can be rotationally adjusted through the pin shaft 23, and the lock tongue 22 can also be rotationally adjusted relative to the pin shaft 23.
[0044] The torsion spring 24 is sleeved on the pin shaft 23, one end of the torsion spring 24 extends into the first embedding groove 224 and then connects with or abuts against the groove wall corresponding to the first embedding groove 224, and the other end of the torsion spring 24 extends into the second embedding groove 214 and then connects with or abuts against the groove wall corresponding to the second embedding groove 214. The torsion spring 24 applies elastic force to the lock tongue 22, allowing the lock tongue 22 to rotate toward the outside of the lock hook 21, so that the abutting end face 223 of the lock tongue 22 fits with the blocking portion 212.
[0045] Furthermore, the first end 221 of the lock tongue 22 is also provided with a connecting tube 25, and through holes are provided on opposite end surfaces of the connecting tube 25 to facilitate the insertion of the pin 23. Opposite openings are provided on the side of the connecting tube 25, and the middle part of the torsion spring 24 can be inserted into the connecting tube 25 from the openings. The connecting tube 25 is preferably fixedly connected to the first end 221 of the lock tongue 22, and one end of the torsion spring 24 extends from the other opening of the connecting tube 25 and enters the first embedding groove 224. A connecting hole corresponding to the through hole is provided at the groove wall corresponding to the second embedding groove 214 of the lock hook 21, so that the pin 23 is inserted. In this way, the pin 23 passes through the connecting hole, the through hole and the torsion spring 24, so as to realize the connection between the lock tongue 22, the torsion spring 24 and the lock hook 21, and the end of the pin 23 can be fixedly connected to the lock hook 21, so that the pin 23 can be rotated and adjusted around the pin 23 through the connecting tube 25.
[0046] In a specific embodiment of the present invention, Figure 2 and Figure 3 As shown, the size of the locking tongue 22 is matched with the size of the opening 211 , and the inner side surface of the locking tongue 22 and the inner side surface of the locking hook 21 can be enclosed to form a closed connection space.
[0047] The pendant head can be installed on the corresponding chain body through the closed connection space. The connection space is opened or closed by the rotation of the lock tongue 22, which can facilitate the installation and removal of the pendant head.
[0048] Furthermore, the size of the lock tongue 22 is 1 / 4 to 1 / 5 of the overall size of the switch buckle, the size of the lock tongue 22 is preferably 1 / 4 of the size of the switch buckle, and the size of the lock hook 21 is preferably 3 / 4 of the size of the switch buckle.
