AI Technical Summary
When the transparent cover of the existing fire helmet is adjusted for use, the elasticity of the shrapnel is reduced, resulting in reduced positioning accuracy of the transparent cover after adjustment.
A limiting mechanism is adopted, including an insert rod, a retaining ring, a spring and a sliding hole structure. The transparent cover is rotated outside the helmet by rotating it, and the spring acts on the retaining ring to make the insert rod enter the support block, limiting the transparent cover and ensuring that the limit is stable after adjustment.
The transparent cover is stably limited to avoid loosening and improve the adjustment accuracy.

Technical Field
[0001] The utility model relates to the technical field of helmets, in particular to a fire emergency rescue helmet. Background Art
[0002] The utility model patent, with patent authorization announcement number CN216932053U, discloses a fire helmet comprising a protective shell and a buffer layer. The protective shell has an inner cavity with a sponge pad inside. The sponge pad is connected to an inner lining layer at its other end. The buffer layer is connected to the top of the inner lining layer. The inner side of the buffer layer has a buffer cavity, and the inner cavity of the buffer cavity is provided with a buffer block. The fire helmet, which uses a flame-retardant layer and a neck guard, can effectively protect the wearer during firefighting operations, preventing excessive fires from causing burns to the wearer, which could cause unnecessary trouble. The flame-retardant layer is made of flame-retardant material and can effectively prevent the helmet from naturally igniting in high-temperature environments. The neck guard protects the back of the firefighter's neck, preventing high-temperature burns on the back of the firefighter's neck, which could cause injury and affect subsequent rescue operations.
[0003] However, in the prior art, when the transparent cover of the helmet is being adjusted for use, it is generally adjusted and fitted by means of a spring. After the device has been used for a long time, the elasticity of the spring decreases, resulting in a decrease in the positioning accuracy of the transparent cover after adjustment.
