CN2173427Y - Electronic warning band for safety helmet - Google Patents

Abstract

The utility model discloses an electronic warning band for a safety helmet, which is characterized in that a plurality of red light-emitting diodes are arranged on the utility model; the utility model is sheathed on the lower edge of the safety helmet and fixed to a helmet body by adopting intermittent light emission as a light source to make the utility model also have favorable warning effect at night.

Description

Electronic warning band for safety helmet

The utility model relates to a kind of electronics that uses band of warning on safety helmet.

The safety helmet that uses has anticollision and the two kinds of functions of warning, in the prior art at present, the function of warning of safety helmet adopts yellow or orange cap body is realized, it is single that this method exists color, and the effect of warning is poor, has almost completely lost shortcomings such as the effect of warning at night.

The purpose of this utility model provides a kind of electronics that uses band of warning on safety helmet, place it on the safety helmet, remove the body color that increases safety helmet by day, make the safety helmet rich color, strengthen outside its effect of warning, the more important thing is that it can initiatively send redness intermittently at night and glisten, and makes safety helmet also have the effect of significantly warning at night.

The purpose of this utility model is achieved in that installs eight red light emitting diodes as warning light source on a yellow or orange double-deck annular strap, the light source of warning adopts its effect of warning of the luminous reinforcement of batch (-type).During use annular strap is enclosed within the safety helmet lower edge, relies on the elastic cloth on the belt body to be fixed on the cap body.

Advantage of the present utility model is: (1) adopts intermittently the luminous redness light source of warning, and makes safety helmet also have the good effect of warning at night.(2) become two body colors by the single main body look, make the safety helmet rich color, strengthened its effect of warning by day, (3) adopt the endless belt, make it be applicable to various safety helmets.

Fig. 3 is the cut-open view after Fig. 1 embodiment amplifies along the A-A line

Fig. 4 is the electronic-circuit diagram of Fig. 1 embodiment

Fig. 5 is that Fig. 1 embodiment goes up the actual structural drawing that uses the pupil with safety helmet (being commonly called as small yellow cap).

Below in conjunction with drawings and Examples the utility model is elaborated.

Illustrate in the structural drawing of the utility model embodiment at Fig. 1, power pack 1 is placed in the place ahead of endless belt 2, is distributed in the outside of annular strap 2 as 8 light emitting diodes 3 of the light source of warning.Power switch 5 is placed on the appliances power source box 1.

Fig. 2 illustrates the horizontally disposed of the utility model embodiment, and elastic cloth 4 is arranged in the rear of endless belt 2, and connects with the method for endless belt 2 employing machines seams.

Fig. 3 illustrates the inner structure of annular strap 2, and lead 6 has been placed in the rear portion of the plastic strip 7 of skeleton function, and the rear end horizontal of light emitting diode 3 and is exposed by the hole on the annular strap 2 on plastic strip 7.

Fig. 4 illustrates in the electron diagram of the utility model embodiment, forms intermittent signal generator jointly by integrated circuit NE555 and R1, R2, C1, and intermittently trigger triode T1 makes the 3 intermittently conductings of 8 light emitting diodes, realizes intermittently luminous.

Fig. 5 illustrate the utility model the pupil with safety helmet on the actual structural drawing that uses, this device is enclosed within cap body 8 lower edges, relies on the convergent force of elastic cloth 4 to be fixed on the cap body.

Claims (2)

1, a kind of electronics that uses on safety helmet band of warning is characterized in that: adopt annular strap (2), be enclosed within on the safety helmet cap body; Lay several red light emitting diodes (3) as warning light source in annular strap (2) outside; The inner plastics row culture skeleton that adopts of annular strap (2).

2, according to the described used for safety helmet electronics of claim 1 band of warning, it is characterized in that: adopt the main body of integrated circuit N555, realize that several light emitting diodes (3) are intermittently luminous as the signal source at intermittence.
