The design of such face masks takes into account the curve of the human face contour, making the wearer more comfortable and having a higher fitting degree. It can be a protective mask for industrial safety or a design in medical masks, which can better fit the face and provide more effective protection.

[0003] In the prior art, some curved face masks are provided with magic tapes on the sides to fix the curved face masks on the wearer's head. The magic tapes are not convenient to tighten, resulting in the curved face masks being easily detached from the wearer's head when worn, and it is not convenient to wear the curved face masks. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that in the prior art, some curved face masks are provided with magic tapes on the sides to fix the curved face masks on the wearer's head. The magic tapes are not convenient to tighten, resulting in the curved face masks being easily detached from the wearer's head when worn, and it is not convenient to wear the curved face masks, and to propose a curved face mask that is convenient to tighten.

[0005] In order to achieve the above purpose, the present invention adopts the following technical scheme: A curved face mask that is convenient to tighten, including a headband ring, a docking seat and an external arc ring. The mask is fixedly arranged on the side of the external arc ring by screws. A top blocking arc plate is fixedly arranged on the top of the external arc ring. A docking seat is fixedly arranged at the edge position of the side of the headband ring. A belt slot is opened at the edge position of the side of the docking seat. A restraint belt is movably inserted into the belt slot. A tightening assembly for tightening the restraint belt is arranged on the docking seat.

[0006] Optionally, an extension column is fixedly arranged on the outer side of the docking seat, and the outer wall of the extension column movably passes through the end of the side of the external arc ring.

[0007] Optionally, an anti-detachment bolt is screwed into the end of the extension column, and a locking dial is screwed into the side of the extension column on one side of the external arc ring.

[0008] Optionally, the tightening assembly includes a winding column, a storage ratchet and a limiting member. The winding column is vertically rotatably arranged on the docking seat. A corrugated head is arranged on the top of the winding column. A storage ratchet is fixedly arranged on the outer wall of the top of the winding column.

[0009] Optionally, the limiting member includes a wedge-shaped block, a connecting column and a connecting spring. A receiving groove is opened on the side of the docking seat, and a fixed disk is fixedly arranged at the end of the receiving groove.

[0010] Optionally, a connecting column is movably inserted into the side surface of the fixed disk. A wedge-shaped block is fixedly arranged at the end of the connecting column. One end of the outer wall of the connecting column is fixedly connected to one end of a connecting spring, and the other end of the connecting spring is fixedly connected to the side surface of the fixed disk.

[0011] Compared with the prior art, the present invention has the following advantages: 1. The main structure of the present invention includes an external arc ring, a headband ring and a top baffle arc plate. A face mask is fixedly arranged on the side surface of the external arc ring. The headband ring is used for fixing the whole face mask to the head. The headband ring and the external arc ring are rotatably connected through a docking seat. Therefore, when not in use, the face mask can be flipped out from the wearer's face.

[0012] 2. The present invention is provided with a restraint belt on the docking seat and a winding component on the docking seat. The restraint belt can replace the traditional magic tape. Under the action of the winding component, the restraint belt can be tightened, thus effectively solving the problem that when the arc-shaped face mask with a traditional magic tape is worn, it is easy to fall off from the wearer's head and is not convenient for wearing the arc-shaped face mask.
