When in use, each male buckle 104 is combined with the shoulder belt buckle 106 first, and then the male buckle 104 is inserted into the female buckle 102 to complete the fastening of the infant safety belt buckle 100 .

FIG. 2 is an exploded view of the infant safety belt buckle 100 , and FIG. 3 is a schematic diagram of the female buckle 102 . 1, 2 and 3 together, the female buckle 102 includes a housing 113, the first through hole 107 is provided on one side of the housing 113, the central area of the housing 113 is provided with a first opening 114, And the casing 113 is respectively provided with a second opening 116 and a third opening 118 on the left and right sides of the first opening 114, and the pair of male buckles 104 can be plugged into the second opening 116 and the third opening respectively. In the opening 118 . The female buckle 102 further includes a button 119 , wherein the button 119 is slidably connected to the first opening 114 . In addition, the housing 113 is further provided with two pairs of first bosses 120, which are symmetrically arranged adjacent to the second opening 116 and the third opening 118, and each pair of first bosses 120 is provided with a Gap 121.

Inside the button 119 are a pair of symmetrical second protrusions 122 , a third protrusion 124 disposed on the second protrusions 122 , and a plurality of hooks 126 . Each second boss 122 is respectively disposed at a position corresponding to each gap 121, and each second boss 122 is respectively provided with a first pushing surface 122A on the side edge facing each first boss 120, and each third boss 124 A second abutting surface 124A is disposed in the corresponding gap 121 facing the housing 113 . The hooks 126 can prevent the button 119 from disengaging from the first opening 114 when the button 119 is installed on the first opening 114 .

Continuing to refer to FIG. 1 and FIG. 2 , a horizontal bar 130 is disposed in the second through hole 108 of each male buckle 104 . The belt 111 can wrap around the horizontal bar 130 . On the side edge 104A of the male buckle 104 opposite to the second through hole 108, a pair of mutually symmetrical buckle hooks 136 and an elastic arm 138 protrude, and the elastic arm 138 is located between the two buckle hooks 136, and the buckle hook The position of 136 corresponds to the first protrusion 120 of the casing 113 and the first pushing surface 122A of the button 119 , and the position of the elastic arm 138 corresponds to the gap 121 of the casing 113 and the second pushing surface 124A of the button 119 . In addition, several guide strips 146 are connected to the side edge 104A of the male buckle 104 , and the distances W1 and W2 (refer to FIG. 2 ) between the guide strips 146 are not equal. As for each shoulder belt buckle 106 , it further includes a slot 142 and a plurality of engaging projections 144 surrounding the slot 142 .

FIG. 4 is a schematic diagram illustrating the fastening of the male buckle 104 and the female buckle 102 with the shoulder belt buckle 106 attached thereto. As shown in FIG. 4, when the male buckle 104 is locked with the female buckle 102, the hook 136 and the spring arm 138 of each male buckle 104 extend into the corresponding second opening 116 and the third opening 118 respectively, and The clasps 136 buckle the first protrusions 120 from the outside, and the elastic arms 138 respectively extend into the gaps 121 inside the first protrusions 120 .

FIG. 5 is a cross-sectional view along line A of FIG. 1 . FIG. 6 is a cross-sectional view illustrating line B in FIG. 1 . Referring to Fig. 4, Fig. 5, and Fig. 6 together, when the male buckle 104 and the shoulder belt buckle 106 are intended to be combined with the female buckle 102 to fix the child on a child seat, the buckles on the pair of male buckles 104 The hook 136 and the elastic arm 138 will pass through the slot 142 corresponding to the shoulder belt buckle 106, and enter the female buckle 102 from the second opening 116 and the third opening 118, and then pass through the first hook 136 and the female buckle 102. The protrusion 120 engages to lock the male buckle 104 and the female buckle 102 , and the elastic arm 138 is located in the gap 121 . As for the engaging protrusion 144 of the shoulder strap buckle 106 , it is used to assist the male buckle 104 to engage with the female buckle 102 . By virtue of the elasticity of the hook 136 of the male buckle 104, the first pushing surface 122A of the push button 119 is pushed to move the button 119 upwards. At this moment, the first pushing surface 122A of the button 119 abuts against the buckle 136 of the male buckle 104 , the second pushing surface 124A of the button 119 is adjacent to or abuts against the elastic arm 138 of the male buckle 104, and the shoulder strap buckle 106 can be fixed on both sides of the female buckle 102 by the male buckle 104, and the pair of male buckles There is a distance L1 between the elastic arms 138 on the 104 .

When the male buckle 104 and the female buckle 102 are to be released, the button 119 is pressed so that the button 119 moves in a first direction D1, and the pair of first pushing surfaces 122A will push the corresponding buckle hooks 136 towards the opposite direction respectively. The second direction D2 and a third direction D3 move, wherein the second direction D2 and the third direction D3 are respectively perpendicular to the first direction D1, so that the clasp 136 that originally buckles the first boss 120 will gradually move from the first boss 120 Disengage from the table 120, and the male buckle 104 and the female buckle 102 will also switch from the locked state to an unlocked state. When the buckle hook 136 disengages from the first boss 120, the second abutting surface 124A pushes down to the elastic arm 138, and the elastic recovery force of the elastic arm 138 will push the pair of male buckles 104 towards the opposite side respectively. The fourth direction D4 and a fifth direction D5 move, the fourth direction D4 and the fifth direction D5 are perpendicular to the second direction D2 and the third direction D3, and the fourth direction D4 and the fifth direction D5 are perpendicular to the first direction D1. When the two male buckles 104 are moving towards the fourth direction D4 and the fifth direction D5 respectively, the distance L1 between the two elastic arms 138 will gradually become longer, and the hooks 136 and the springs on the pair of male buckles 104 will The arm 138 will move away from the corresponding second opening 116 and the third opening 118. At this time, the pair of male buckles 104 can be synchronously moved away from the slot 142 of the shoulder strap buckle 106 or the male buckle 104 and the shoulder strap buckle 106 can be moved together. move away from each other so that the infant can be moved away from the child seat. In other embodiments, the safety belt buckle 100 may not include the shoulder belt buckle 106 , and the child can be fixed on the child seat only by the engagement of the male buckle 104 and the female buckle 102 .

Referring to Fig. 2, Fig. 5 and Fig. 6 together, a fool-proof design is further provided between the male buckle 104 and the female buckle 102, and several guide strips 146 are connected to the side edge 104A of the male buckle 104, and the guide strips The distances W1, W2 between 146 are not equal. As for the female buckle 102, there is a male buckle guide groove 148 corresponding to each guide strip 146. Each guide strip 146 must be aligned with the male buckle guide groove 148 in the opposite position, so that the male buckle 104 can be plugged in. In the second opening 116 and the third opening 118 of the female buckle 102, this design can prevent a pair of male buckles 104 from correspondingly engaging with the two sides of the female buckle 102, and prevent from engaging from the wrong side Or up and down the opposite, resulting in the possibility of danger.

In the infant safety belt buckle 100 provided by the present invention, adults only need to press the button 106 on the female buckle 102, and the male buckle 104 can be released from the female buckle 102, and the elastic restoring force of the elastic arm 138 will make the male buckle 104 release from the female buckle 102. The female buckle 102 springs off, so the operation is very labor-saving and smooth. The user does not need to press the button 119 to release the lock, and also needs to remove the two male buckles 104 from the female buckle 102, which is more convenient to use.

The above description is based on multiple different embodiments of the present invention, wherein each feature can be implemented singly or in different combinations. Therefore, the disclosure of the embodiments of the present invention is a specific example to illustrate the principles of the present invention, and the present invention should not be limited to the disclosed embodiments.
