[0035] like Figure 1-7As shown, a buckle is provided, comprising: a first buckle body 1, the first buckle body 1 is provided with a first installation space 2, a first hook body 3 is provided in the first installation space 2, the first hook body 3 is hinged in the first installation space 2 through a first rotating shaft 4, and a first unlocking unit 5 for unlocking the rotation of the first hook body 3 is provided in the first installation space 2; a second buckle body 6, the second buckle body 6 is provided with a second installation space 7, a second hook body 8 is provided in the second installation space 7, the second hook body 8 is hinged in the second installation space 7 through a second rotating shaft 9, and a second unlocking unit 10 for unlocking the rotation of the second hook body 8 is provided in the second installation space 7; wherein, when the first buckle body 1 and the second buckle body 6 are connected, the first hook body 3 and the second hook body 8 are hooked and cooperated with each other, the first unlocking unit 5 limits the rotation of the first hook body 3, and the second unlocking unit 10 limits the rotation of the second hook body 8.

[0036] In view of the technical problems described in the background technology, a buckle is provided. When in use, when the first buckle body 1 and the second buckle body 6 are matched, the first hook body 3 and the second hook body 8 are hooked and matched. After the first hook body 3 and the second hook body 8 are rotated in place, the first unlocking unit 5 performs limited rotation on the first hook body 3, and the second unlocking unit 10 performs limited rotation on the second hook body 8. The first hook body 3 and the second hook body 8 are used to bear the force, so that when the tension is applied, the force is better dispersed to the lock hook, and the force will not be concentrated on one point or one surface, so that the overall tension value of the buckle is greatly increased, and it can withstand greater tension.

[0037] refer to Figure 4-5 As shown, a first guide strip 11 is provided on a first side of the first buckle body 1, and a first guide groove 12 matching the first guide strip 11 is provided on a first side of the second buckle body 6. A second guide groove 13 is provided on a second side of the first buckle body 1, and a second guide strip 14 matching the second guide groove 13 is provided on a second side of the second buckle body 6.

[0038] When in use, by adding a guide bar and a guide groove structure, it is set on the side of the buckle body. When the first buckle body 1 is connected with the second buckle body 6, the guide bar and the guide groove are slidably matched. Under the action of the guide, the connection between the first buckle body 1 and the second buckle body 6 is smoother. The length of the guide groove should be sufficient to allow the guide bar to move into place in the guide groove when the hook body is rotated into place.

[0039] refer to Figure 8-11As shown, the first hook body 3 is provided with a first notch 15 at the position of the first rotating shaft 4, the first notch 15 is provided with a first torsion spring 16 for the first hook body 3 to rotate, and the first torsion spring 16 is sleeved on the first rotating shaft 4. The second hook body 8 is provided with a second notch 17 at the position of the second rotating shaft 9, the second notch 17 is provided with a second torsion spring 18 for the second hook body 8 to rotate, and the second torsion spring 18 is sleeved on the second rotating shaft 9.

[0040] In order to realize automatic resetting of the first hook body 3 and the second hook body 8 when the buckle is separated, the notch arranged on the hook body is used to install the torsion spring. When the first buckle body 1 and the second buckle body 6 are connected, the torsion spring is in a state of force compression. When the first unlocking unit 5 and the second unlocking unit 10 are pressed, the first buckle body 1 and the second buckle body 6 are separated, and the first torsion spring 16 and the second torsion spring 18 push the first hook body 3 and the second hook body 8 to reset.

[0041] Reference Figure 12-15 As shown, the first unlocking unit 5 includes a first limit block 19 and a first spring 20, the first limit block 19 is connected to the first spring 20, at least a part of the first limit block 19 is exposed outside the first buckle body 1, the first hook body 3 is provided with a first notch 21 that cooperates with the first limit block 19 to limit, and the first limit block 19 is pressed by an external force to release the limit of the first hook body 3. The second unlocking unit 10 includes a second limit block 22 and a second spring 23, the second limit block 22 is connected to the second spring 23, at least a part of the second limit block 22 is exposed outside the second buckle body 6, the second hook body 8 is provided with a second notch 24 that cooperates with the second limit block 22 to limit, and the second limit block 22 is pressed by an external force to release the limit of the second hook body 8. The first hook body 3 is in a C-shape as a whole. The second hook body 8 is in a C-shape as a whole.

[0042] The above provides a specific unlocking and limiting method. During use, when the first buckle body 1 and the second buckle body 6 collide, the first hook body 3 and the second hook body 8 touch each other, and then rotate. At the same time, the guide bar is placed in the guide groove and slides. When the first hook body 3 and the second hook body 8 rotate to the set angle, that is, the lower end position of the first limit block 19 is reset under the action of the first spring 20, and the lower end position of the first limit block 19 contacts the first notch 21 of the first hook body 3, forming a limit on the first hook body 3; the lower end position of the second limit block 22 is reset under the action of the second spring 23, and the lower end position of the second limit block 22 contacts the second notch 24 of the second hook body 8, forming a limit on the second hook body 8.

[0043] At the same time, in the present invention, the first unlocking unit 5 or the second unlocking unit 10 is pressed separately, and the buckle cannot be opened due to the hooking and cooperation between the first hook body 3 and the second hook body 8, which can better ensure the risk of the buckle being disengaged. When unlocking, it is necessary to press the first unlocking unit 5 or the second unlocking unit 10 switch at the same time. After pressing, when the first buckle body 1 and the second buckle body 6 are separated, the first torsion spring 16 and the second torsion spring 18 release their elastic force, and the first hook body 3 and the second hook body 8 rotate around the first rotating shaft 4 and the second rotating shaft 9 respectively, thereby completing the unlocking state.

[0044] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
