Abstract

The utility model provides a safety helmet which comprises a helmet body, a strap, a power supply switch and a battery box lighting component, etc. A triangular reflection sign is arranged on the front part and the top part of the helmet body. A lighting diode with super high brightness is used as the lighting component. The utility model is a helmet used for building construction with favorable warning effect and good lighting effect.

Description

Safety cap

The utility model relates to a kind of construction safety cap.

The workman need wear safety cap in the building construction process.Traditional following shortcoming of safety cap ubiquity: 1, self is not luminous, uses night and does not warn effect.2, can not throw light on, night the field lighting lamp according to less than the place still need use flashlight.At this situation, application number is 87210586, and the patent that the application name is called " a kind of safety cap that light-emitting device is arranged " proposes to use the SL3909 integrated circuit to form oscillator drives red luminotron flicker illuminating to show personnel positions hereof.But red luminotron luminous intensity only 20-100mcd does not have illuminating effect, and using has limitation, and the luminous tube volume is too little simultaneously, and light beam is very narrow, is difficult to find for the tower crane operating personnel of tens meters eminences.Application number is 98236039, and the patent that the application name is called " the noctilucence reflection safety helmet " then has been coated with the fluorescigenic coating of one deck energy on helmet whole outer surface, and this coating is met high light can reflection ray.But fluorescence is very weak, and allotment coating is operated more complicated in process of production, and large tracts of land brushing simultaneously is very waste also.Circular the reflective of the helmet all is the epitome of bulb In the view of the observer, and the reflective spot area is very little, and the caution effect is also bad.Therefore, concerning the builder, need a kind of light, the good illumination effect is arranged, the safety cap of obvious caution effect is arranged simultaneously.

The utility model provides a kind of light, good illumination effect, simultaneously the safety cap of good warning effect.

The utility model achieves the above object by following means.Triangle adhesive sticker reflecting sign is all posted in top and front portion at safety cap.According to the most responsive principle of human eye diabolo identification, reflecting sign selects for use triangle can farthest be different from object on every side, thereby the caution effect is best.The price of adhesive sticker reflective sheeting is very low, and triangle is that easy cutting does not produce the corner again, therefore adopts triangle adhesive sticker reflecting sign, and production cost is extremely low.The extra-bright light emitting diode of two coloured light that turn white is housed in the safety cap front, and the luminescent spectrum of this light emitting diode falls into the sensitive range of human eye, thereby human eye perceives is bright especially, and the incandescent lamp of subjective sensation and 3w is similar.Because the operating current of this luminous tube is 10mA only, so power supply can adopt alkaline battery No. 5, whole like this device connects the only heavy 50-80 gram of battery, and is light especially.

Can be elaborated embodiment of the present utility model in conjunction with the accompanying drawings.

Fig. 1 is that the safety cap master looks perspective view

Fig. 2 is the safety cap front view

Fig. 3 safety cap is overlooked partial sectional view

(1) is the cap body among the figure; (2) be cingulum; (3) be power switch; (4) be battery case; (5) be light-emitting component; (6) be cap body top; (7) be cap body front portion; (8) be reflecting sign; (9) be reflecting sign; (10) be the inner electric wire that connects.

Cap body (1) adopts the ABS engineering plastics injection molded, and the surface scribbles the mute lac varnish of orange-yellow caution.Cingulum (2) adopts polyvinyl chloride to make.Power switch (3) adopts the single-pole single-throw(SPST toggle switch, and length is 20mm.Battery case (4) adopts commercially available 3v battery case, tightens together with Luo silk and cap body (1) rear portion of two pieces of diameter 3 * 8mm.Light-emitting component (5) adopts the extra-bright pure white light emitting diode of diameter 5mm, and model is 5WUHCA, and the luminous intensity of this luminous tube is 3000-10000mcd, and about 15 ° of the luminous angle of emergence is well suited for doing illumination and uses.The purpose of two luminous tubes of luminous tube employing is to guarantee that enough luminous intensities are arranged in the present embodiment, bores the circular hole of two diameter 5.5mm during making in cap body front portion (7), clings with resin glue after luminous tube is put into again.Reflecting sign (8) (9) is made of the adhesive sticker reflective sheeting that contains glass microballoon, is cut into the equilateral triangle that the length of side is 5-8cm with cutting knife during making, is attached to cap body front portion (7) then and cap body top (6) gets final product.Reflecting sign (8) (9) and cap body (1) can form huge contrast because of reflecting rate different at night, and very easily identification is observed in 30 meters high tower cranes and also can be seen clearly, and the caution effect is very obvious.

The utility model provides a kind of safety measure for the construction personnel, also is a kind of illuminations of practicality simultaneously, and very light, welcome by the workmen.China builder is millions of approximately, thereby the utlity model has boundless market prospects, and enterprise produces it can obtain good benefit.

Claims

1, a kind of safety cap of being made up of cap body (1), cingulum (2), power switch (3), battery case (4), light-emitting component (5) is characterized in that cap body top (6) and cap body front portion (7) post adhesive sticker reflecting sign (8) (9); Light-emitting component (5) is the extra-bright light emitting diode.

2, the safety cap according to claim 1 is characterized in that adhesive sticker reflecting sign (8) (9) is shaped as triangle.
