Detailed Description

The safety helmet for building construction can be made of the following materials, and is not limited to the following materials, for example: stainless steel, plastic, aluminum alloy, foamed metal, rubber, air bag balloon, and the like.

FIG. 1 is a side view of a safety helmet for building construction according to an embodiment of the present invention; the safety helmet of the embodiment is mainly used for being worn on the heads of different workers in the construction process, so that the safety of the heads can be protected under the conditions of accidents and dangers, and damages are reduced.

The safety helmet for building construction of the embodiment of the invention comprises: a semi-spherical shell 1, a flexible inner lining plate 3 and a plurality of sliding plates 2; the shell is generally a plastic shell and is of an integrated structure and is used for bearing most of impact force.

Each sliding plate 2 has a tile-shaped structure, and each sliding plate 2 has an inner arc surface and an outer arc surface; tile-shaped structure can effectually be crooked, can also take place elastic deformation under huge impact force to protect the head.

A plurality of rubber rollers 21 are arranged on the outer arc surface, and the sliding plate 2 is in contact with the inner wall of the shell 1 through the rubber rollers 21; thereby enabling a certain displacement effect of the slide plate with respect to the housing.

an air bag 22 is arranged on the intrados, and the sliding plate 2 is in contact with the inner lining plate 3 through the air bag 22; thereby ensuring that the sliding plate can be comfortably contacted with the inner lining plate after being in the fixed position.

The air bag is generally a silica gel air bag, and high-pressure gas is sealed in the air bag to ensure the elasticity.

In this embodiment, interior lining board generally adopts metal mesh or plastic net to make, and the gasbag not only can guarantee the travelling comfort that interior lining board and human contact, can also provide good shock attenuation effect.

The outer shell 2 and the inner lining plate 3 are connected through a plurality of bolts 10; the slide plate 2 is a metal foam slide plate. The sliding plate in this embodiment is generally made of foamed metallic aluminum.

Metal foams are also known as metal foams; foam metal refers to a special metal material containing foam pores. Through the unique structural characteristics, the foam metal has a series of good advantages of small density, good heat insulation performance, good sound insulation performance, capability of absorbing electromagnetic waves and the like, and is a novel material which is gradually developed along with human science and technology and is commonly used for a series of industrial developments of aerospace, petrochemical industry and the like. Compared with common sintered porous metal, the metal material containing foam pores has higher porosity and larger pore size which can reach 7 mm. Since the foam metal is a two-phase composite material consisting of a metal matrix skeleton continuous phase and a gas pore dispersed phase or continuous phase, the properties of the foam metal depend on the metal matrix, the porosity and the gas pore structure used and are influenced by the preparation process. In general, the mechanical properties of the metal foam decrease with increasing porosity, and the electrical conductivity and thermal conductivity decrease exponentially. When the foam metal is subjected to pressure, the foam metal has excellent impact energy absorption and special buffer protection due to the stress area increase caused by air hole collapse and the material strain hardening effect, and is also one of the main purposes of the foam metal, and the foam metal has the capacity of absorbing energy and simultaneously controls the maximum acting force acting on a protected object to be below the limit of causing damage. Porous foams are well suited for such applications. By controlling its relative density, the strength of the metal foam can be adjusted over a wide range. In addition, the material can bear great compression strain under constant stress, so that great amount of energy is absorbed without high stress.

The safety helmet for building construction of the embodiment is provided with at least one sliding plate 2 between two bolts 10. Therefore, each bolt can influence the cheap angle of the sliding plate after adjustment, and the sliding plate is more suitable for the head of a human body.

specifically, as shown in fig. 1, a silica gel protective joint 11 is installed at one end of the bolt 10, and a screwing device 12 is arranged at the other end; the silicone protective joint 11 is used for directly contacting with a human body, so that the bolt can not stab the head of the human body in collision.

The bolt 10 is connected with the inner lining plate 3 through a silica gel protective joint 11; the screwing device 12 is fixed on the outer side of the shell 1; the tightening device is typically a rotatable nut that is rotatable relative to the housing and is mounted on the housing.

The tightening device 12 rotates to tighten the bolt 10, and the silica gel protective joint 11 drives the lining plate 3 to move towards the housing 1.

Because the lining plate adopts a net structure, any position of the lining plate can be connected with the bolt.

In the actual use process, different bolts are screwed according to different positions of the head of a human body, so that the position and the angle of the sliding plate can be adjusted to be attached to different positions of the human body; in addition, the position of the sliding plate can be adjusted by a small amount in order to avoid discomfort of contacting a part of the sliding plate with a human body during adjustment of the sliding plate.

The safety helmet for building construction of the present embodiment, wherein the outer shell 1 is a porous aluminum alloy member, and the inner lining plate 3 is a metal mesh structure.

Further, the edge of the outer side of the outer shell 1 is provided with a reinforcing rib 15 to enhance the strength of the edge of the outer shell.

the safety helmet for building construction in the embodiment further comprises a steel sheet spring 4; the section of the steel sheet spring 4 is of a C-shaped structure;

one end of the steel spring 4 is fixed on the shell 1, and the other end is connected with the inner lining plate 3.

the steel sheet spring has certain elasticity, can avoid interior bushing plate to misplace or slide relative to the shell. Under the condition that the bolt adjusts the sliding plate, the steel sheet spring can be properly pulled so as to ensure the comfort of the human body.

Preferably, the steel plate spring 3 is provided with a tightening belt 5. The tightening strap is used for fixing the safety helmet at the chin of the human body.

In addition, the safety helmet for building construction has the advantages of low manufacturing cost, compact structural design, ingenious structure, stable finished product quality, attractive appearance and convenient use and adjustment, and is suitable for the internal structures of various safety helmets.
