In pivoted hole 60a radially virtual first straight line L1, and first straight line L1 pass through the arc surface circular arc in The heart O, virtual second straight line L2 are perpendicular to first straight line L1 and pass through first hole portion 61a, first hole portion 61a two-phase To hole wall in distance measured on second straight line L2 be the first width R1；Virtual one the 3rd straight line L3 passes through the center of arc O and perpendicular to first straight line L1, and the 3rd straight line L3 is relative parallel to first straight line L1, the two of second hole portion 62a Hole wall is the second width R2 in distance measured on the 3rd straight line L3, and second width R2 is more than first width R1.

Formed with an at least convex portion 62 on the arc surface, in the present embodiment, the quantity of an at least convex portion 62 is two, And two convex portion 62 is located in two relative positions by center of arc O.Virtual one the 4th straight line L4 passes through two convex portion 62 With the center of arc O of the arc surface, in institute's ranging on the 4th straight line L4 from for one the 3rd width wherein between two convex portion 62 R3, and the 3rd width R3 is less than second width R2.

The bolt 70 is slightly U-shaped, and two-phase heteropleural is formed 72 at 71 and one second at one first respectively, wherein the bolt 70 should 71 are provided with an annular groove 71a at first；This of the bolt 70 72 has an a positioning hole 72a at second in lateral, and the bolt 70 this 72 ends are formed with a projection 721 at two, and the external diameter of the projection 721 is more than the groove width of the neck 15.

Please coordinate shown in Fig. 7 a, this at first 71 wear two perforation 16 of the body 10 and second locking part 60 should Pivoted hole 60a.At the first of the bolt 70 71 have mutually back to one first face 711 and one second face 712, wherein first face At a distance of one the 4th width R4 between 711 and second face 712, and the 4th width R4 is slightly less than first width R1；This first The Breadth Maximum at place 71 is one the 5th width R5, and wherein the 5th width R5 is more than the first width R1 and the 3rd width R3, And the 5th width R5 be slightly less than second width R2.

The bolt 70 can be operated in pivot between a closed position S1 and an open position S2 and be put.It please coordinate Fig. 2 and Fig. 7 a, when this Bolt 70 is when the S1 of the closed position, the pushing tow of the second elastic component 50 second locking part 60, makes second locking part 60 toward departing from The direction movement of the body 10, until the first hole portion 61a of second locking part 60 be butted on the bolt 70 this 71 at first, make this Second locking part 60 is maintained at one the 3rd position P3, and simultaneously, the first face 711 and second face 712 of the bolt 70 are supported respectively The two-phase for being against pivoted hole 60a first hole portion 61a is faced the wall and meditated on face, to cause the bolt 70 can not be relative to the pivot of body 10 Pendulum.

See shown in Fig. 5 a, when the bolt 70 is in closed position S1, this of the bolt 70 72 is butted on the neck 15 at second Cell wall, and the positioning hole 72a of bolt 70 is relative with first tank 11.The pushing tow of first elastic component 30 tightening latch 24, makes the tightening latch 24 are located in positioning hole 72a positioned at first position P1 and the fastening part 241, and make it that the bolt 70 can not be relative to the body 10 pivots are put.

The baffle ring 80 is sheathed at the first of the bolt 70 71 and is butted on the peritreme of one perforation 16 of the body 10, the baffle ring 80 Internal diameter and the bolt 70 this at first 71 annular groove 71a be engaged, and the external diameter of the baffle ring 80 is more than the internal diameter of the perforation 16.

Each portion's component and correlation of the above-mentioned buckle for safety belts attachment means 100 for the utility model first preferred embodiment The explanation of position.Its occupation mode is hereby described again as after.It please see Fig. 5 a and Fig. 4 b again, apply an external force F1 in the sliding block 22, make this Sliding block 22 moves along the cell wall of chute 13 and toward the direction away from the neck 15, and drives the tightening latch 24 to be moved from first position P1 Moving to second place P2, makes positioning hole 72a of the fastening part 241 of the tightening latch 24 away from the bolt 70.

Simultaneously, Fig. 7 a and Fig. 7 b please be coordinate, apply another external force F2 in second locking part 60, make the second lock tug Part 60 from the 3rd position P3 toward second tank 12 inside be moved to one the 4th position P4, and make the bolt 70 first at 71 In pivoted hole 60a the second hole portion 62a.

Second locking part 60 when the 4th position P4, due to the bolt 70 this at second 72 no longer by the fastening part 241 are limited in the neck 15, and the bolt 70 this at first 71 the 5th width R5 be less than second width R2, therefore, The bolt 70 now can be operated and the arc surface of second hole portion 62a along pivoted hole 60a is switched to the open position Put S2 (see Fig. 8).

Please coordinate again shown in Fig. 9, and because the 5th width R5 is more than the 3rd width R3, therefore the bolt 70 is switched to one During predetermined angle, this of the bolt 70 71 is resisted against two convex portion 62 at first, and then can reach the angle of pivot for limiting the bolt 70 The function of degree.

Operator can be combined the body 10 with the suspender belt, and by located at the clasp set of the safety belt as the bolt 70 On.Yu Hou, then the pivot of bolt 70 is swung back into closed position S1, the bolt 70 first at 71 second holes for leaving pivoted hole 60a After portion 62a hole wall, compressed second elastic component 50 soon discharges and the pushing tow position of the second locking part 60 to the 3rd P3, with lock pull the bolt 70 this 71 at first；The external force F1 for operating the sliding block 22 is removed, compressed first elastic component 30 revolves I.e. simultaneously the pushing tow tightening latch 24 returns back to first position P1 for release, the fastening part 241 is equipped in the positioning hole 72a of the bolt 70 In, with lock pull the bolt 70 this 72 at second, and complete to connect the suspender belt and the safety belt.

Further, since 71 be arranged with the baffle ring 80 at the first of the bolt 70, the bolt 70 second at 72 ends formed with this Projection 721；When using the buckle for safety belts attachment means 100, the baffle ring 80, both projections 721 and the clasp distinguish position In the both sides of body 10, therefore when bolt 70 is pullled by external force, the baffle ring 80 is born against in the hole of the perforation 16 with the projection 721 Edge and the groove edge of neck 15, to prevent from being sliding out the body 10 in the bolt 70.

Because the bolt 70 can be put by the relative pivot of body 10 of operation, therefore in the operation buckle for safety belts attachment means 100 When, the body 10 for being connected to the suspender belt is not easy impacted because of the pivot of the bolt 70 pendulum, and the bolt 70 also will not be in unblock to locking During the body 10 separate；In addition, first locking part 20 can not only unlock easily with second locking part 60, by the bolt 70 when returning back to closed position S1, and first locking part 20 and the i.e. automatic lock of second locking part 60 are pulled the bolt 70, even if operation , still can the easy operation buckle for safety belts attachment means 100 even if person wears gloves.

The preferred possible embodiments of the utility model are the foregoing is only, such as using the utility model specification and power Equivalence changes carried out by the claimed scope of profit, ought to be included in the scope of the claims of the present utility model.
