DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0026] Embodiments of the present utility model:

[0027] A combined safety helmet comprises a safety helmet 1, an eye mask 2 and a breathing mask 3 are arranged at the lower part of the safety helmet 1, and the eye mask 2 is located between the safety helmet 1 and the breathing mask 3;

[0028] The first connecting belt 4 is symmetrically fixed on both sides of the eye mask 2, and the end of the first connecting belt 4 away from the eye mask 2 is clamped in the adjusting buckle 8. By setting the adjusting buckle 8, the length of the area where the first connecting belt 4 is used can be adjusted. It should be noted that: the area where the first connecting belt 4 is used is the area between the eye mask 2 and the adjusting buckle 8, and the upper part of the adjusting buckle 8 is rotatably installed on the "U"-shaped frame 9, and the "U"-shaped frame 9 is fixed to the inner wall of the safety helmet 1. Through the setting of the first connecting belt 4, the adjusting buckle 8 and the "U"-shaped frame 9, the safety helmet 1 and the eye mask 2 form an integral structure.

[0029] A second connecting belt 5 is symmetrically fixed to the inner wall of the safety helmet 1, and "U"-shaped rods (not shown in the figure) are fixed to the two inner side walls of the breathing mask 3. One end of one of the second connecting belts 5 passes through one of the "U"-shaped rods and is installed with a first clamping assembly, and one end of the other second connecting belt 5 passes through the other "U"-shaped rod and is installed with a second clamping assembly. Through the arrangement of the first clamping assembly and the second clamping assembly, the use area of ​​the two second connecting belts 5 can be adjusted. The area used by the second connecting belt 5 is the position where the breathing mask 3 is connected to the first clamping assembly and the second clamping assembly, so that it can be suitable for workers with different face shapes; through the arrangement of the second connecting belt 5, the safety helmet 1 and the breathing mask 3 form an integral structure.

[0030] Specifically, the breathing mask 3 includes a mask body 31 and a filter cover 32, two "U"-shaped rods are symmetrically fixed on the inner wall of the filter cover 32, and a first fixing seat 33 is fixed on the outer side of the mask body 31, and a second fixing seat 34 is fixed on the inner side of the filter cover 32, and the second fixing seat 34 can be inserted into the interior of the first fixing seat 33, so that the mask body 31 and the filter cover 32 can be disassembled, and the filter cover 32 can be replaced, ensuring a good effect.

[0031] More specifically: a plurality of fixing cylinders 331 are fixed to the outer side of the first fixing seat 33, and one end of the fixing cylinder 331 is connected to the inner side wall of the first fixing seat 33, a spring 332 is fixed to the inner end wall of the fixing cylinder 331, and one end of the spring 332 is fitted with the steel ball 333, and a clamping hole 341 is opened on the outer side of the second fixing seat 34. Through the setting of the fixing cylinder 331, the spring 332, the steel ball 333 and the clamping hole 341, the cover body 31 and the filter cover 32 are fastened to prevent the cover body 31 and the filter cover 32 from loosening during use.

[0032] There are two ways to fasten the second connecting belt 5 away from the end of the helmet 1. The present application can adopt any of the following fastening methods:

[0033] The first fastening method: a Velcro velvet surface 61 is fixed to the outer side of one end of the second connecting strap 5 away from the safety helmet 1, and a Velcro hook surface 71 is fixed to the inner side of the other end of the second connecting strap 5 away from the safety helmet 1, and the length of the Velcro velvet surface 61 is longer than the length of the Velcro hook surface 71. Through the arrangement of the Velcro velvet surface 61 and the Velcro hook surface 71, the ends of the two second connecting straps 5 can be fastened to ensure that the breathing mask 3 can be worn.

[0034] The second fastening method: a plurality of hanging holes 72 are equidistantly fixed on the outer side of one end of the second connecting belt 5 away from the safety helmet 1, and a hook 62 is fixed on the other end of the second connecting belt 5 away from the safety helmet 1. The hook 62 can be hung on the corresponding hanging hole 72 according to the user's needs. On the one hand, the tightness of the breathing mask 3 can be adjusted according to the size of the user's face, and on the other hand, it plays the role of fastening the ends of the two second connecting belts 5.

[0035] When the user wears the protective tool, the safety helmet 1 is first worn. If the eye mask 2 is worn, the eye mask 2 is first placed on the glasses in advance, and then the adjustment buckle 8 is adjusted to adjust the length of the area used by the first connecting belt 4, so that the eye mask 2 can be tightened, thereby completing the work of wearing the eye mask 2; if the breathing mask 3 is worn, the breathing mask 3 is first placed on the nose in advance, and then one end of the two second connecting belts 5 is pulled to tighten the first clamping assembly 6 and the second clamping assembly 7, thereby completing the work of wearing the breathing mask 3.

[0036] When the user wants to replace the filter cover 32, first take out one end of the two second connecting belts 5 from the "U"-shaped rod respectively, so that the breathing mask 3 is separated from the safety helmet 1, and then pull the cover body 31 and the filter cover 32. The clamping hole 341 can squeeze the spherical surface of the steel ball 333. When the steel ball 333 is squeezed, it moves into the fixing cylinder 331 and squeezes the spring 332. After the steel ball 333 moves to the inside of the fixing cylinder 331, the cover body 31 and the filter cover 32 can be separated, and then the new filter cover 32 can be installed on the cover body 31, and the "U"-shaped rods on both sides of the filter cover 32 are installed on the second connecting belt 5 again, thereby completing the replacement work.
