Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment:

the utility model provides a safety helmet for construction, includes cap shell 1 and arc 2, first inlet port 3 has been seted up at the top of 1 internal surface of cap shell, the top fixedly connected with spring 4 of 1 internal surface of cap shell, the top fixedly connected with connecting rod 5 of arc 2, the top fixedly connected with supporting shoe 6 of connecting rod 5, the bottom of spring 4 with the top fixed connection of arc 2, spring 4 with connecting rod 5 cup joints, the bottom fixedly connected with lug 7 of arc 2, the top of 1 external surface of cap shell just is located the outside fixedly connected with radiator unit 8 of first inlet port 3.

Spring 4 is compression spring, and compression spring is the coil spring who bears axial pressure, and the material cross-section that it used is mostly circular, also has rectangle and stranded steel silk to roll up, and the spring is generally the equidistant, and compression spring's shape has: cylindrical, conical, well convex and well concave and a small amount of non-circular etc. have certain clearance between compression spring's circle and the circle, spring contraction deformation when receiving external load, store the deformation ability, and the quantity of spring 4 is 14 and above, and lug 7 is the rubber material, makes and leaves certain space between constructor's top of the head and the arc 2, makes things convenient for the circulation of air.

In this embodiment, the heat dissipation assembly 8 includes a heat dissipation box 801, the top fixedly connected with fan 802 of heat dissipation box 801 internal surface, second inlet hole 803 has all been seted up to the left and right sides of heat dissipation box 801 internal surface, the centre of heat dissipation box 801 external surface is provided with solar panel 804.

In this embodiment, the bottom of the inner surface of the cap shell 1 is provided with a cap hoop 9, and the bottom of the cap shell 1 is fixedly connected with a visor 10.

In this embodiment, the lower jaw straps 11 are fixedly connected to the left and right sides of the bottom of the cap shell 1.

In this embodiment, an illumination lamp 12 is fixedly connected to the middle of the outer surface of the cap shell 1 and on the top of the visor 10.

In this embodiment, a reflective tape 13 is provided on the back of the outer surface of the cap case 1.

The working principle is as follows: after constructor took cap shell 1, the crown of the head contacted with lug 7 on the arc 2, simultaneously cap hoop 9 also cooperates and makes the cap shell 1 can be stable lay constructor's overhead, later hang chin area 11 in constructor's chin, make cap shell 1 fixed more stable, when the object pounded and fell on cap shell 1, when cap shell 1 moves down, arc 2 still contacts with constructor's crown of the head, then spring 4 atress shrink, contract supporting shoe 6 and cap shell 1 inside contact back when spring 4, connecting rod 5 and supporting shoe 6 prop cap shell 1, spring 4 cushions the power of striking and falls, avoid constructor's crown of the head direct with cap shell 1 contact, when having protected constructor personal safety, also more comfortable.

After a period of time, if the staff thinks the crown is sultry, then can start through the outside control switch control fan 802 of cap shell 1, fan 802 inhales outside air through second inlet port 803 inside of heat dissipation case 801, then blows into the inside of cap shell 1 through first inlet port 3, then gaseous everywhere cavity through on the arc 2 gets into the bottom of arc 2, dispels the heat to constructor's crown, has improved constructor's comfort level.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
