Description

Technical Field

[0001] The utility model relates to the technical field of safety buckles, in particular to a safety seat buckle. Background Art

[0002] The safety seat buckle is an important component of the child safety seat. It is used to connect the safety belt and realize the quick locking and unlocking function of the safety belt. The existing safety seat buckle includes a female buckle and two left and right male buckles. The buckle on the male buckle is engaged with the block on the female buckle to realize the locking function. This design causes the tension applied by the safety belt on the male buckle to be borne entirely by the buckle and the female buckle, which makes the male buckle at risk of slipping when the tension is large. In addition, since the male buckle and the female buckle are only connected by the buckle, the male buckle is prone to shaking, and the buckle is subject to a large bending force and is easily damaged. At the same time, the locking part of the existing buckle is locked by opening a groove on the outer side of the buckle, and its firmness is low, and there is a risk of disengagement.

[0026] Working principle: When using the utility model, the safety belts of the two shoulders are installed through the third mounting holes 210 on the first male buckle 21 and the second male buckle 25, and the safety belt of the crotch is installed through the first mounting hole 13. The first male buckle 21 and the second male buckle 25 are combined together, so that the first positioning block 22 is inserted into the second positioning groove 26, the second positioning block 23 is inserted into the third positioning groove 27, and the protrusion 24 is inserted into the card slot 28. Then the card buckle body 29 is inserted into the gap between the second plug hole 18 and the first plug hole 17, so that the third positioning block 211 is inserted into the first positioning groove 12, and the locking assembly 3 inside the female buckle assembly 1 is used to lock the shoulder. The tension exerted by the safety belt on the first male buckle 21 and the second male buckle 25 includes a tension to both sides and a tension vertically upward. The tension to both sides will cause the first male buckle 21 and the second male buckle 25 to have a tendency to separate to both sides, and this tendency is offset by the first positioning block 22, the second positioning block 23 and the protrusion 24. The vertically upward tension is offset by the buckle body 29 in cooperation with the locking assembly 3. When the user leans forward, the first male buckle 21 and the second male buckle 25 will have a tendency to fall out backwards, and this tendency is offset by the third positioning block 211, so as to prevent the buckle body 29 from being subjected to a large bending force. Among them, the first shell 11 and the second shell 14 is the outer shell of the female buckle assembly 1, the notch 15 is used to accommodate the third positioning block 211, and the second mounting hole 16 is used to install the locking assembly 3; when the locking assembly 3 is locked, the buckle body 29 is inserted into the gap between the first baffle 33 and the second baffle 34, and the buckle body 29 is clamped by the insert block 322. At this time, the top block 334 is pressed down by the buckle body 29, and the second spring 335 is in a compressed state; when unlocking, the button 31 is pressed down to push the contact piece 321 through the guide groove 312, so that the spring piece 32 is deformed, and the insert block 322 is disengaged from the first slot 331 and the second slot 341, so that the buckle body 29 loses the lock. , under the reset action of the second spring 335, the top block 334 pushes the buckle body 29 to pop out. When the button 31 is pressed down, the first stopper 311 moves down along the first slide groove 324, and cooperates with the second stopper 323 to compress the first spring 326. Therefore, after releasing the button 31, under the reset action of the first spring 326, the button 31 will automatically pop out and reset. The third slide groove 332 and the fifth slide groove 342 are used to accommodate the first stopper 311, the second slide groove 325, the fourth slide groove 333 and the sixth slide groove 343 are used to accommodate the top block 334, and the force of the plug block 322 is borne by the first slot 331 and the second slot 341, so the locking is more secure.
