[0021] The specific embodiments of the present invention will be further described below with reference to the drawings and examples. The following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

[0022] As shown in Figures 1 to 3, the present invention is a new type of respirator equipment, including a back frame body 1, the back frame body 1 is provided with a back frame lever 2, a handle 3 and a lumbar back plate 4, back The upper part of the frame body 1 is provided with a back frame pull rod 2, the lower part of the back frame body 1 is provided with a waist back plate 4, the back frame body 1 is provided with a handle 3 in the middle, and the lower part of the back frame body 1 is also provided with a waist back plate moving chute 5, The waist back plate 4 is connected to the sliding seat 6, the waist back plate 4 and the sliding seat 6 are provided with torsion rubber 7, and the waist back plate 4 is connected to the sliding seat card 9 through the sliding seat connecting rod 8, and the sliding seat card 9 is at the waist The movement of the upper and lower moving chute 5 on the back plate drives the movement of the lumbar back plate 4, and the pressure reducer mounting frame 10 is provided under the upper and lower moving chute 5 of the lumbar back plate, and the hose installation slot 11 is provided in the back frame rod 2. The upper part of the back frame body 1 is also provided with a spring clip 12.

[0023] The back frame body 1 is provided with a gas cylinder anti-collision rubber pad 13, which is arranged in front of the spring clip 12, and the bottom of the back frame body 1 is provided with a back frame bottom anti-collision rubber 14, and the back The top of the frame pull rod 2 is provided with left and right shoulder strap installation holes 15, the two sides of the waist back plate 4 are provided with left and right waist belt installation holes 16, and the spring clip 12 is provided with a head-up display installation compartment 17.
