Embodiment 1

[0028] The present invention provides such Figure 1-5 As shown, a fire-fighting smoke-proof and flame-retardant protective clothing with an openable and closing ventilation structure includes a hat part 1, a jacket part 2 and a trousers part 3, and the hat part 1 and the jacket part 2 are integrally formed. The upper garment part 2 and the trouser part 3 are connected in a ring with Velcro 4, and the upper garment part 2 and the trouser part 3 are connected by the Velcro 4 envelopingly, so as to ensure the integration performance of the entire protective clothing and protect the wearer in all directions;

[0029] The soft material of the hat part 1 is provided with an inner protective shell 101, the inner protective shell 101 is set to match the contour of the human head, and the front side of the inner protective shell 101 is provided with a sliding protective glass plate 102 The inner protective shell 101 is made of hard non-metallic material, which not only improves the pr...

Embodiment 2

[0036] The flame-retardant layer 5 includes fireproof fiber fabrics, bamboo fiber fabrics, ramie fiber fabrics, nylon fibers and cotton fiber fabrics, and the nylon fibers and cotton fibers are a sheath-core structure, and the sheath-core structure includes a core layer and a cortex, The core layer is cotton fiber, the cortex is set as nylon fiber, and the cotton fiber is wrapped in the nylon fiber layer. The ignition point of the ramie fiber fabric is better than that of bamboo fiber and ramie fiber blended fabric, and the cost is lower. low and can be used as a substitute.

Abstract

The invention discloses smoke-proof and flame-retardant protective clothing with an openable and closable ventilation structure for fire protection. The protective clothing comprises a hat part, a jacket part and a pants part, wherein the hat part and the jacket part are integrally formed; the hat part, the jacket part and the pants part are all provided with soft material layers; each soft material layer comprises a flame-retardant layer, a heat insulation layer, a skin-friendly layer and a protective strip layer; each heat insulation layer is arranged between one flame-retardant layer and the corresponding skin-friendly layer; each protective strip layer is arranged between one heat insulation layer and the corresponding skin-friendly layer; a ventilation assembly is arranged in the middle of the front side of the jacket part; and a one-way valve body is arranged in an air inlet pipe. By discharging heat in the protective clothing, burning heat sensation of firemen is relieved in time; and an anti-falling assembly is arranged on the back of the jacket part and comprises a fixing plate and a protective plate, and an arc-shaped support plate is elastically connected to the top end of a first bent part, so that protection or buffering of relative force can be provided, and the firemen are effectively protected in time.

Description

technical field [0001] The invention relates to the technical field of protective equipment, in particular to a smoke-proof and flame-retardant protective clothing for fire-fighting with an openable and closed ventilation structure. Background technique [0002] Protective clothing is usually made of dense fabrics, various fibers and membrane materials to prevent external pathogenic microorganisms, chemicals, dust and other harmful factors from causing harm to the staff, and to ensure a reliable protective effect. Generally speaking, with the improvement of protective ability, the air permeability and moisture permeability of protective workwear fabrics decrease rapidly, which seriously hinders the wearer's heat dissipation and perspiration. Gas exchange is the most simple and feasible technical solution. [0003] In order to realize the controlled exchange of gas inside and outside the protective clothing, eliminate the heat dissipation of the wearer's body, and prevent va...
