Abstract

The invention discloses a split type pressure head-up display device which comprises a first shell, a second shell, an elastic U-shaped clamp and a flexible cable. The elastic U-shaped clamp is connected with the first shell and the second shell. The ends of the two sides of the elastic U-shaped clamp are each provided with a clamp hook extending inwards. The flexible cable is connected to the bottom end of the first shell and the bottom end of the second shell. According to the split type pressure head-up display device, the spilt type structural design is adopted, the elastic U-clamped clamp is adopted to be used in cooperation with various breathing mask in a fixed mode, and disassembling, assembling and maintenance are easy. The elastic U-shaped clamp has the elasticity, can be opened and closed and is used for connecting the two shells, so that the whole split type pressure head-up display device adapts to breathing masks of different types, the using flexibility is greatly improved, the production cost is reduced, and the market prospect is wide.

Description

technical field [0001] The invention relates to a split pressure head-up display device. Background technique [0002] In a dangerous environment, the life safety of rescuers (such as firefighters) is mainly guaranteed by gas respirators (such as air respirators, oxygen respirators), and rescuers must always ensure that the gas pressure in the gas cylinder is in a safe range. The pressure value of the gas in the gas cylinder is generally indicated by a pointer mechanical pressure gauge or a digital electronic pressure gauge. In order to avoid frequent observation of the pressure gauge value during intense rescue work and distract the attention of rescuers, the pressure head-up device installed in the respirator mask (with pictures) can be adjusted by the number of LED lights, color changes and flashing methods. A combination that dynamically represents the gas pressure information of the current gas cylinder. Rescuers only need to use peripheral vision to observe during th...
