Description

Technical Field

[0001] The utility model belongs to the technical field of helmets and relates to a helmet with a telescopic and adjustable face mask. Background Art

[0002] Workers working in potentially hazardous environments such as construction sites are required to wear safety helmets to prevent serious head trauma in the event of an accident. At the same time, for certain activities that pose a risk of facial injury or require eye protection, workers must also wear a transparent mask in addition to their safety helmets.

[0003] Some helmets currently available on the market are equipped with masks, which are rotatably arranged on the outside of the helmet. By bending the mask downward, the mask is flipped down from the top of the helmet to the front of the user for use; by bending the mask upward, the mask is flipped up from the front end of the helmet to the top for storage.

[0004] However, this type of mask has the following disadvantages: when not in use, the mask is stored on the top of the helmet and is exposed to the air for a long time, which is easy to accumulate dust and dirt, and the mask is easy to hide dirt and dirt, which affects the vision when in use; and the existing helmets of this type cannot adjust the height of the mask to be lowered, and the applicability is not strong.

As Figure 4 shown, so that the pressing block 13 abuts against the face mask 3; during disassembly, the two pressing blocks 13 are swung inwards to separate the pressing blocks 13 from the face mask 3 and embed them into the avoidance holes 14, and then the mounting piece 5 can be pulled out.

[0031] As Figure 6 and Figure 8 shown, the convex block 10 is located on the back surface of the guide member 6. A positioning groove is formed on the front surface of the guide member 6. A clamping block 16 is fixedly arranged on the face mask 3, and the clamping block 16 is embedded in the positioning groove; a positioning hole 17 is further formed on the guide member 6. A positioning column 18 is fixedly arranged on the face mask 3, and the positioning column 18 is inserted into the positioning hole 17. The face mask 3 and the guide member 6 are installed and positioned through the cooperation of the positioning column 18 and the positioning hole 17, and the positioning groove and the clamping block 16.
