SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a safety helmet cap shell that gas permeability is good, rational in infrastructure, the four sides is ventilative, guarantees the air mobility of overhead in the safety helmet, and the gas permeability is good, wears comfortablely.

In order to achieve the purpose, the utility model provides a safety helmet shell with good air permeability, which comprises a shell, wherein one end of the shell is provided with a brim, the brim is connected with a water chute positioned on the outer edge of the shell, accessory sockets positioned on two sides of the shell are arranged in the water chute, a bulge positioned on the shell is arranged between the accessory sockets, the bulge is arranged corresponding to the brim, and the bulge is provided with first air holes which are uniformly distributed;

the top of casing is equipped with first strengthening rib and the second strengthening rib that is nearly V-arrangement and distributes, first strengthening rib is close to the one end of brim of a hat with the second strengthening rib is close to the one end of brim of a hat is crossing, the lateral wall of first strengthening rib with be equipped with the second bleeder vent that corresponds the distribution on the lateral wall of second strengthening rib, first strengthening rib with be equipped with the boss between the second strengthening rib, the boss with first bleeder vent the second bleeder vent is linked together, the boss is kept away from be equipped with the third bleeder vent on the lateral wall of brim of a hat, the third bleeder vent with the second bleeder vent is nearly triangle-shaped and distributes.

Preferably, the side wall of the first reinforcing rib and the side wall of the second reinforcing rib are perpendicular to the section of the shell, and the side wall of the boss is perpendicular to the section of the shell.

Preferably, the accessory socket has a width smaller than that of the water chute.

Preferably, an LED lamp is inserted into the accessory socket.

Therefore, the utility model adopts the above structure the good safety helmet cap shell of gas permeability, rational in infrastructure, the air mobility of overhead in the safety helmet is guaranteed in the four sides is ventilative, and the gas permeability is good, wears comfortablely.

The technical solution of the present invention is further described in detail by the accompanying drawings and examples.

Detailed Description

The following describes embodiments of the present invention with reference to the accompanying drawings.

Fig. 1 is the utility model discloses the schematic diagram of the safety helmet cap shell embodiment that the gas permeability is good, fig. 2 is the utility model discloses the schematic diagram of the embodiment of the axonometric drawing of the safety helmet cap shell that the gas permeability is good, as shown in the figure, a safety helmet cap shell that the gas permeability is good, including casing 1, casing 1's one end is equipped with brim of a hat 2, and brim of a hat 2 can be used for the sunshade and rain-proof. The brim 2 is connected with the guiding gutter 3 that is located the casing 1 outer edge, and guiding gutter 3 is used for leading rainwater to brim 2 department outflow, prevents that the rainwater from flowing into in the collar of wearer along casing 1. Be equipped with in the guiding gutter 3 and be located the accessory socket 4 of 1 both sides of casing, the interpolation of accessory socket 4 is equipped with the LED lamp, and the LED lamp can throw light on for the safety helmet person of wearing at night during operation, and the safety helmet person of wearing is seen at night to other people of being convenient for simultaneously, guarantees person of wearing's safety. The width of the accessory socket 4 is smaller than that of the water chute 3, so that the smoothness of the water chute 3 is ensured. Between the fitting sockets 4, there are protrusions 5 on the housing 1, the protrusions 5 being used to increase the strength of the housing 1. The protrusion 5 corresponds to the brim 2, and the protrusion 5 is provided with first air holes 6 which are uniformly distributed, and the first air holes 6 are used for ensuring the air permeability of the front end of the safety helmet shell 1.

The top of casing 1 is equipped with first strengthening rib 7 and the second strengthening rib 8 that is nearly V-arrangement and distributes, and the lateral wall of first strengthening rib 7, the lateral wall of second strengthening rib 7 all are perpendicular with casing 1's tangent plane, and first strengthening rib 7 and second strengthening rib 8 are used for increasing casing 1's intensity. The one end that first strengthening rib 7 is close to brim of a hat 2 and the one end that second strengthening rib 8 is close to brim of a hat 2 are crossing, are equipped with the second bleeder vent 9 that corresponds the distribution on the lateral wall of first strengthening rib 7 and the lateral wall of second strengthening rib 8, and second bleeder vent 9 makes the air of safety helmet both sides realize the convection current, and the air current can be smooth and easy the entering and flow casing 1 and take away the heat, guarantees the gas permeability of safety helmet both sides.
