The hook buckle is simple in structure to facilitate production by manufacturers, is convenient to mount or disassemble, and is conveniently used by users. In daily use, touching the button 3 at one side by mistake may cause falling of the male buckle and the female buckle. With the structure, when the button 3 on any side is pressed, only one side of the locking block 2 may be lifted, and the male buckle and the female buckle cannot be unlocked. Thus, falling due to touching by mistake by a user can be avoided in daily use, and product use stability and better user experience can be ensured. The side release buckle is used for baby slings, which can greatly ensure babies' safety.
[0024] A limiting part 8 is arranged between the locking block 2 and the housing 1. The limiting part 8 includes a plurality of limiting columns 9 protruding from the housing 1 or the mounting seat 6, and limiting holes 10 formed on the locking block 2 to match the limiting columns 9. The limiting columns 9 penetrate the limiting holes 10. The limiting columns 9 protrude above the locking block 2. The limiting part 8 is used for limiting a position of the locking block 2 to prevent the locking block 2 from shaking in the housing 1. Meanwhile, the limiting part 8 is further used for limiting a moving direction of the locking block 2. The locking block 2 moves vertically along a trajectory of the limiting columns 9, such that the locking block is kept moving perpendicularly and is prevented from deviation during vertical movement.
[0025] A rebound member 11 is arranged between the locking block 2 and the upper cover 5. The rebound member 11 includes a reset spring. The locking block 2 is unlocked through upward moving, and then is reset by the return spring. In a normal state, the locking block 2 is pressed by the return spring all the time, such that the locking block is tightly placed on the mounting seat 6. In the design, one rebound members 11 is arranged at a center, which is not limited herein, or a plurality of rebound members 11 may be arranged according to an actual resilience condition.
[0026] The locking block 2 is provided with a protruding spring post 25. A bottom of the upper cover 5 is provided with a spring hole 26. The spring post 25 and the spring hole 26 match the rebound member 11.

[0027] Two sides of the housing 1 are provided with button chambers 12. The buttons 3 are movably assembled in button chambers 6, and outer end portions of the buttons 3 are exposed outside the button chambers 12, so as to be used for unlocking through pressing.
[0028] The guiding blocks 7 are provided with inclined guiding surfaces 13. Two ends of the locking block 2 are in contact with the guiding surfaces 13. When the guiding blocks 7 move inward, the locking block 2 gradually moves upward along the guiding surfaces 13.
[0029] The guiding blocks 7 are provided with first positioning recesses 28. The housing 1 is internally provided with first positioning blocks 27. The two sides of the locking block 2 are provided with guiding recesses 29. The first positioning blocks 27 are located at two sides of the mounting seat 6, and the first positioning blocks 27 are engaged with the first positioning recesses 28 and the guiding recesses 29 simultaneously. The first positioning recesses 28 are driven by the guiding blocks 7 to move transversely on the first positioning blocks 27. Stability of the buttons 3 during movement is enhanced. The guiding recesses 29 move longitudinally on the first positioning blocks 27, and moving stability of the locking block 2 is improved.
[0030] The reset member 4 includes an elastic reset member. The buttons 3 are pressed to press the reset member 4 to be deformed. The buttons 3 are released to reset the reset member 4 through resilience. The reset member 4 is wound around an outer edge of the locking block 2. The reset member 4 and the buttons 3 are integrated to avoid unnecessary assembly and increase connection strength. Centers of upper and lower ends of the housing 1 are provided with second positioning blocks 14. Centers of upper and lower ends of the reset member 4 are provided with second positioning recesses 15 configured to match the second positioning blocks 14. During mounting, the second positioning blocks 14 are snapped into the second positioning recesses 15 to limit the reset member 4, such that moving stability of the reset member 4 is improved, and the reset member 4 is prevented from dislocation after being pressed and deformed repeatedly.
[0031] Two sides of the buttons 3 are provided with protruding stop blocks 16. The stop blocks 16 abut against inner walls of the button chambers 12, so as to prevent the buttons 3 from falling from the button chambers 12.
[0032] A lower surface of the housing 1 is provided with a sliding recess 6 in communication with the mounting seat 6. The female buckle is slidably mounted on the male buckle.
[0033] The male buckle includes a body 18, a base 19 protruding from a center of the body 18, a connecting column 20 extending upward from a center of the base 19, and a fixing block 21 at a center of the connecting column 20. An inner wall of the sliding recess 17 is provided with a limiting step 22 arranged in a U-shaped manner. The connecting column 20 is provided with an annular recess 23 configured to match the limiting steps. During assembling, the annular recess 23 is aligned with the limiting step 22, and mounting is performed in a sliding manner. The male buckle includes a circular male buckle, and may be mounted in a sliding manner at any angle without alignment, which is convenient to use.
[0034] The locking block 2 is provided with a fixing hole 24 configured to match the fixing block 21. During mounting, the buttons 3 at the two sides are pressed to enable the locking block 2 to move upward, and then the female buckle is assembled in a sliding manner. During assembly, the limiting step 22 slides along the annular recess 23 until the fixing block 21 slides directly to a position below the fixing hole 24. In this case, a U-shaped contour of the limiting step 22 abuts against the annular recess 23, and the fixing block cannot further slide inward. Finally, the buttons 3 are released, and the locking block 2 is reset by resilience and moves downward, such that the fixing block 21 is snapped into the fixing hole 24 to achieve fixation. The principle is simple, and clamping is stable.
[0035] One end of the housing 1 is provided with a webbing mounting portion 30. A webbing strap on a backpack or a baby sling is adjustably inserted into the webbing mounting portion 30. The webbing mounting portion 30 is provided with a cover plate 31 that is openable and closable. The cover plate 31 rotates to be opened and closed through shaft connection, which clamps the webbing strap after closed, to prevent the webbing strap from loosening.
