Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of protective appliance, especially relates to a safety helmet with quick dismounting function. BACKGROUND

[0002] Safety helmet is the steel or similar raw material shallow dome hat for protecting head, and is the protective article of preventing the impact object from injuring head, is composed of cap shell, cap lining, chin strap and the like. Cap shell and cap lining leave a certain space between, can buffer, disperse instantaneous impact force, thereby avoiding or reducing the direct injury to head. It is just such cap lining's installation structure is very important, and the usual practice is to set up a plurality of protruding buckle positions on the inner wall of cap shell, thereby being connected with cap lining buckle, but it is very troublesome to form buckle structure on the inner arm of cap shell, needs to adopt strong detachment or inclined top, straight top and the like mechanism to realize in the manufacturing process.

[0003] In addition, in order to facilitate night work, usually a plurality of functional pieces are configured on many safety helmets for binding lighting lamps and the like on the safety helmet, but the installation of functional pieces is basically to set installation holes on cap shell, and then is fixed through smearing glue. But the hole position of installation hole is generally shallow due to the position limitation of cap shell, so the functional piece is prone to fall off with the impact or with the passage of time, which increases the safety hazard. SUMMARY

[0004] The utility model discloses a safety helmet to solve the problems in the background art, the utility model discloses through partial optimization design, can greatly improve the impact resistance of safety helmet, and the lining belt assembly is convenient to disassemble and assemble, is convenient to replace, and production efficiency is high, and the yield is high.

[0005] In order to realize the above-mentioned purpose, the technical scheme of the utility model is as follows: a safety helmet with quick dismounting function, including cap shell, lining belt assembly, the lining belt assembly is fixed in the inside of cap shell through lining belt connecting piece, the cap shell is outwardly protruded and forms the brim and the brim transition section around, the function area is formed in the non-outward protruding part of the both sides of cap shell, and a plurality of functional pieces are equipped in the function area, the functional piece includes insertion section and function section, the front end of insertion section is equipped with barrier strip, the inner wall part area of brim is covered with reinforcing layer, and the reinforcing layer is equipped with reinforcing rib between brim inner wall, the insertion section of functional piece inserts between the interlayer of reinforcing layer and brim inner wall through the brim transition section, the assembly avoiding mouth is set up on the reinforcing layer corresponding to the position of functional piece, the lining belt connecting piece is inserted between the reinforcing layer and the insertion section of functional piece through the assembly avoiding mouth, the front end of function section of functional piece is resisted to the brim transition section after insertion, and the barrier strip of insertion section buckles the rear end face of lining belt connecting piece, so that functional piece and lining belt connecting piece interact and are fixed.

[0006] In order to realize the structure of inner tight and outer loose, facilitate the disassembly of the belt connecting piece, at least in the area corresponding to the assembly avoiding port, the spacing between the reinforcing layer and the inner wall of the brim gradually narrows along the direction of the brim transition section.

[0007] In order to increase the elasticity of the functional part insertion section, facilitate the insertion of the belt connecting piece, the functional part insertion section is provided with elastic holes.

[0008] As a further improvement of the utility model: in order to ensure that the functional part insertion section is close to the belt connecting piece, and the barrier strip holds the functional part insertion section, the insertion section of the functional part is bent towards the direction of the protrusion of the barrier strip.

[0009] In order to improve the impact resistance of the safety helmet, the top area of the helmet shell is convex in the front-rear direction to form a top reinforcing area. In this way, reinforcing areas are formed in the top area and the surrounding brim area of the safety helmet, further improving the quality of the safety helmet.

[0010] As a further improvement of the utility model: in order to further ensure that the barrier strip holds the functional part insertion section, a damping strip is arranged on the rear end surface of the belt connecting piece to increase the width of the connecting surface.

[0013] 2. Since the special mounting buckle position of the belt assembly on the helmet shell is cancelled, the structure of the helmet shell mold is simplified; the original special mounting buckle position needs to be realized by using strong stripping or inclined top, straight top, etc. After improvement, the complex movement mechanism in the mold is cancelled, and the front and rear molds can be realized by knocking, thereby avoiding the risk of product strain and the risk of jamming of mold parts due to inclined top and straight top.

[0014] 3. Due to the optimization of the mold structure, the small special mounting buckle position is cancelled, and the injection molding pressure of the injection molding machine can be appropriately reduced, which can prolong the production life of the machine; at the same time, since the complex movement mechanism in the mold is cancelled, the product defects caused by the mechanism are reduced, which on the one hand can speed up the production rhythm, shorten the injection molding cycle of the product, improve the production efficiency, and on the other hand can greatly improve the yield of the product, making the product more beautiful.

[0015] 4. The utility model makes full use of the space between the reinforcing layer and the inner wall of the brim, adopts the buckle connection mode of the functional part and the belt connecting piece, and firmly fixes them in the interlayer, so that the risk of falling is avoided, and the connection is more reliable.

[0016] 5、The utility model makes full use of the characteristics of the inner gradually narrowing of the sandwich space, forms the structure characteristics of the outer loose and the inner tight, first presses the functional part in the direction of the cap edge inner wall when installing, then inserts the lining band connecting piece through the assembly avoiding mouth, then loosens the functional part to realize the installation and fixed connection of both, and the disassembly and assembly are more quick and convenient.

[0017] 6、The utility model adopts the cap edge, cap top outer convex and sets up the technical means such as reinforcing layer, greatly improves the impact resistance and safety of safety helmet. BRIEF DESCRIPTION OF DRAWINGS
