Specific embodiment:
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of welding face guard, including protective face mask 2,2 upper end of protective face mask are set
Crash helmet 1 is set, is rotatablely connected between crash helmet 1 and protective face mask 2, passes through locking between crash helmet 1 and protective face mask 2
Mechanism carries out locking and unlocking, convenient for adjusting angle when protective face mask 2 uses, and carries out localization process, protective face mask 2 is corresponding
Eye guard 4 is installed in the position of eyes, installs optical filtering telescoping mechanism 7, optical filtering telescoping mechanism 7 at 2 inboard groove 5 of protective face mask
Upper setting optical filtering 6 can make to move to 4 inside of eye guard on optical filtering 6 and be displaced downwardly to receipts by control optical filtering telescoping mechanism 7
Opening is arranged in the position of Na Chu, the corresponding mouth of protective face mask 2, which is arranged antifog plate 9 can by being provided with antifog plate 9
It prevents oral area exhaled gas from hazing on optical filtering 6, reduces worker in welding by being influenced.Rotation connects on the outside of the opening
Connect baffle 8.
It is respectively fixedly connected with rotation axis 3 on 2 two sides upper end inner sidewall of protective face mask, two rotation axis 3 are respectively placed in peace
The mounting groove opened up on 1 two sides lateral wall of the full helmet, is rotatablely connected between rotation axis 3 and the mounting groove.
Locking mechanism uses fastening bolt, and multiple can connect with crash helmet 1 admittedly is equipped on the side wall of protective face mask 2
Fixed fastening bolt.
