[0021] The technical solution of the utility model is further described below in conjunction with specific implementation methods:

[0022] like Figure 5 and Figure 6 As shown, a mask-helmet integrated structure includes a helmet 1, a mask 2 and two connecting units, wherein both ends of the mask 2 are connected to the helmet 1 through a connecting unit respectively. Figure 1 As shown, the connecting unit includes a single-hinge visor connector 3, a helmet connector 4 and a tightening mechanism 5, the single-hinge visor connector 3 is connected to the end of the mask 2, the tightening mechanism 5 is arranged between the single-hinge visor connector 3 and the helmet connector 4, and the helmet connector 4 is connected to the helmet 1.

[0023] like Figure 2 As shown, both ends of the mask 2 are provided with rotating parts 31, and screw holes are provided on the rotating parts 31 and the single-hinged cover connecting part 3. The rotating parts 31 correspond to the single-hinged cover connecting part 3 one by one and are connected by bolts passing through the screw holes. The screw holes are provided with threads matching the bolts. The bolts are used to fix the rotating parts 31 and the single-hinged cover connecting part 3.

[0024] like Figure 4 As shown, the helmet 1 is provided with a mounting port, and the end of the helmet connector 4 is a hook, and the helmet connector 4 is quickly connected to the helmet 1 by matching the mounting port with the hook. The helmet connector 4 is also provided with a through hole, and after the hook at the end of the helmet connector 4 matches the mounting port, the screw is passed through the through hole and matched with the nut to achieve fixation. This part adopts a card connection, and a hinge connection can also achieve the corresponding function.

[0025] like Figure 3 As shown, the tightening mechanism 5 includes a knob 51, a housing 52, an anti-loosening assembly, an adjusting assembly and two connecting straps 53, one end of the two connecting straps 53 is respectively connected to the single-leaf visor connector 3 and the helmet connector 4, the housing 52 is fixed on one connecting strap 53, the knob 51, the anti-loosening assembly and the adjusting assembly are all installed on the housing 52, the other connecting strap 53 is inserted into the housing 52 and the length of the two connecting straps 53 is adjusted by the adjusting assembly. The anti-loosening assembly includes a ratchet 54 and a pawl 55. The adjusting assembly includes a gear 56 and a rack 57, both connecting straps 53 are provided with notches, the racks 57 are arranged on both sides of the notches, and the gear 56 is meshed with the rack 57.
