First of all, please refer to the first to third pictures, which are the improved three-dimensional appearance of the safety helmet chinstrap fastening device of this creation and the schematic diagram of the assembled appearance, which mainly includes:

A buckle seat (1) is provided with a base plate (11) and pivot plates (12) on both sides of the base plate (11), and a buckle (2) is pivotally arranged between the two pivot plates (12). An embedding piece (3) can be embedded between the buckle (2) and the bottom plate (11) to be fastened together; it is characterized in that:

The end of the buckle (2) is provided with a tilting part (21), and there is a hole between the tilting part (21) and the bottom plate (11) of the buckle seat (1) for pulling the buckle (2) Rotating pitch space (A) [as shown in the third figure].

Please refer to Figures 1 to 6. When in operation, the strap fastening device of this invention is used in vehicle helmets, engineering helmets, etc., and the straps on both sides of the helmet are respectively combined with the The buckle seat (1) and the snap-in piece (3); when the user wears the safety helmet, the buckle seat (1) and the snap-in piece (2) are correspondingly embedded through the snap-in piece (3) between them and engage in positioning, and the buckle (2) is further provided with a tooth (22), and the embedded clamp (3) is provided with a mutual locking position corresponding to the tooth (22). The locking tooth (31) of the said tooth part (22) and the said locking tooth (31) are locked and positioned mutually, and the said inserting piece (3) is connected with the said buckle seat (1) and the said card Fasteners (2) come together [as shown in the fourth figure].

When disassembling the embedded part (3), please refer to the sixth figure, the user inserts a single finger into the space (A) between the raised part (21) and the bottom plate (11) At this time, the interlocking part (3) is embedded in the spacing space (A), and the interlocking part (3) forms an angle (X) with respect to the tilting part (21), so The above included angle (X) provides a space for fingers to embed [as shown in the fifth figure]. After the user's finger is inserted, the tilting part (21) is turned outward to rotate the buckle (2), so that the tooth part (22) is disengaged from the locking tooth (31), The embedded clamping part (3) can be smoothly disengaged from the buckle seat (1).
