Description

Novel building safety helmet for working sites

Technical field

The utility model is related to a kind of novel building safety helmet for working sites.

Background technology

Safety cap is labour protection article indispensable on construction site, and the steel worn for protecting the crown or similar raw material are made Shallow dome cap, prevent alluvium injury head protective articles, be made of cap shell, hat lining, lower cheekstrap and back ferrule.Cap shell is in It is hemispherical, firm smooth, and with certain elasticity, hit the impact of object and puncture kinetic energy and mainly born by cap shell, cap shell and cap There are certain spaces between lining, can buffer, disperse instant impact.The cushion performance of wherein safety cap is that the safety of most critical refers to Mark, the cushion performance of existing safety cap need to be continuously improved.

Invention content

Problem to be solved in the utility model is to provide a kind of novel building safety helmet for working sites, overcomes in the prior art Deficiency.

In order to solve the above technical problems, the technical solution adopted in the utility model is：Novel building safety helmet for working sites, packet Cap shell and hat lining are included, there is gap between the cap shell and the hat lining, with cross web beam in the gap, described ten The inner surface of the cap shell is fixed on close to the cap shell edge in the end of word web beam, the cross web beam it is upper Surface has around the uniformly distributed arc buffering sliding slot of the axis of the cap shell；

The inner surface of the cap shell has buffers strut, the buffering strut correspondingly with the arc buffering sliding slot Upper end be fixed on the inner surface of the cap shell at the center of the cap shell, lower end is limited in the arc buffering sliding slot It is interior, there is gap between the lower end of the buffering strut and the bottom surface of the arc buffering sliding slot.

Further, the lower face of the buffering strut has groove and spherical surface body, and the spherical surface body is embedded in the groove Interior, the lower face of the buffering strut is stretched out hereinafter, the spherical surface physical efficiency rolls in the groove in the lower part of the spherical surface body.

The utility model has the advantages and positive effects of：Due to the adoption of the above technical scheme, it is reasonable in design, delay Punching performance is high, can protect the safety on worker head to greatest extent, more convenient to use；With simple in structure, easy to maintenance, processing At low cost, the advantages that security performance is high.

Specific embodiment

As shown in Figure 1, 2, the utility model provides a kind of novel building safety helmet for working sites, including cap shell 1 and hat lining (figure In do not show), there is gap, with cross web beam 2 in gap, the end of cross web beam 2 is consolidated between cap shell 1 and hat lining Due to cap shell 1 inner surface close to 1 edge of cap shell, the upper surface of cross web beam 2 has the axis around cap shell 1 uniformly distributed Arc buffering sliding slot 4；

The inner surface of cap shell 1 has buffers strut 3 correspondingly with arc buffering sliding slot 4, and the upper end of buffering strut 3 is consolidated Due to cap shell 1 inner surface at the center of cap shell 1, lower end is limited in arc buffering sliding slot 4, buffer strut 3 lower end There is gap between the bottom surface of arc buffering sliding slot 4.

In above structure, when cap shell 1 is acted on by external force, the sky between the elasticity of cap shell 1 itself and cap shell 1 and hat lining Gap can play the role of energy-absorbing buffering, and when foreign impacts power makes more greatly the top of cap shell 1 broken, the lower end for buffering strut 3 can be with The bottom surface contact of arc buffering sliding slot 4, at this time since the contact surface is arc so that the lower end of buffering strut 3 can not rest on In cambered surface, but with cambered surface direction slide downward, further cushioning effect is played with this, reduces by 3 institute of cross web beam The impact force being subject to, it can be seen that, which has triple buffer structure, respectively：(1) the sky between cap shell 1 and hat lining Gap；(2) the slip between strut 3 and arc buffering sliding slot 4 is buffered；(3) cross web beam 3.

The lower face for buffering strut 3 has groove and spherical surface body 5, and spherical surface body 5 is embedded in groove, the lower part of spherical surface body 5 The lower face of buffering strut 3 is stretched out hereinafter, spherical surface body 5 can roll in groove.The setting of spherical surface body 5 reduces buffering strut 3 With the frictional force between arc buffering sliding slot 4.

The embodiment of the utility model is described in detail above, but the content is only the preferable of the utility model Embodiment, it is impossible to be construed as limiting the scope of the utility model.It is made according to the scope of application of this utility model equal Deng variation and improvement etc., should all still belong within the patent covering scope of the utility model.
