Abstract

A rotating warning lamp comprises a base (4), a lamp cover (1) covered on the base and a power mechanism (5) arranged in the base. An output shaft (57) of the power mechanism traverses through the top face of the base and is connected with a light reflecting lampshade (2). A lamp bulb (3) is arranged at the center of the light reflecting lampshade. The utility model is characterized in that the light reflecting lampshade (2) shows a double-bowl shape in a heel piece. The double-bowl shape light reflecting lampshade (2) can be inserted and connected with the output shaft (57) of the power mechanism through a hollow pipe (21) stretching downwards. The output shaft (57) can be a hollow shaft; a strut (31) of the lamp bulb stretches upwards from the base (4) through the hollow part of the output shaft and reaches the center of the light reflecting lampshade (2) through the hollow pipe (21) of the light reflecting lampshade (2). Compared with the prior art, the utility model can reflect the light sent out by the lamp bulb in a 360 DEG range by rotating only 180 DEG and send out warning to all around and the efficiency is increased by one times as the double-bowl shape light reflecting lampshade is adopted, further, the design of the hollow output shaft makes the whole structure be simpler and easier to be produced with lower cost.

Description

A kind of rotary warning lamp

Technical field

The utility model relates to a kind of warning lamp, particularly a kind of rotary warning lamp.

Background technology

Warning lamp is widely used in roadblock caution, scene of a traffic accident protection, job site caution, pavement maintenance caution and the indication of the alert point of various public safety at present.The structure of existing rotary warning lamp roughly comprises base and is positioned at motor, transmission mechanism, lamp socket, bulb and the reflection shield of base that motor drives lamp socket and bulb or reflection shield rotation by transmission mechanism.The many in addition various improvement on transmission mechanism of the warning lamp of existing different structure, have and adopt frictional drive, as in the patent No. being disclosed technical scheme in the Chinese utility model patent " friction driving type warning lamp " of ZL92238388.X, also have and adopt the worm and gear transmission, as in the patent No. being disclosed technical scheme in the Chinese utility model patent " rotating component of warning lamp " of ZL97221676.6, also there is direct usefulness motor-driven, as in the patent No. being disclosed technical scheme in the Chinese utility model patent " warning lamp revolving gear " of ZL00208678.6.Yet in these technical schemes, reflection shield all is the bowl-shape of hemisphere face shape, needs to drive its rotation and can go out to warn light in the internal reflection of 360 ° of full-shape scopes for 360 °.

Summary of the invention

Technical problem to be solved in the utility model is that a kind of rotary warning lamp that the reflector Rotate 180 ° can go out to warn light in the internal reflection of 360 ° of full-shape scopes that only need drive is provided at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this rotary warning lamp includes base, covers on the lampshade on the base and is arranged on the interior actuating unit of base, the output shaft of actuating unit passes base top surface and links to each other with the reflection shield that is positioned at lampshade, the center of reflection shield is provided with bulb, it is characterized in that described reflection shield is to lean against the two bowl-shape of one.

Described two bowl-shape reflection shield can be by its hollow pipe that extends downwards and the output shaft grafting one of actuating unit; This output shaft can be hollow, and the pillar of bulb promptly extends upward and through the hollow pipe of the described reflection shield center to reflection shield from base through the hollow part of this output shaft.

Described actuating unit can comprise motor, driving wheel, belt, drive, driving wheel links to each other with the output shaft of motor, belt connects driving wheel and drive respectively, and the central authorities of drive have the worm screw of an evagination, and above-mentioned output shaft bottom has the worm gear that matches with it at corresponding position; During work, motor drives driving wheel by its rotating shaft and rotates, and drives drive through belt again and rotates, so the worm screw of drive central authorities promptly drives described worm gear and then drives the output shaft rotation, finally causes the rotation of reflection shield.

Compared with prior art, the utility model is owing to adopted two bowl-shape reflection shields, therefore, Rotate 180 ° can go out the light that bulb sends in the internal reflection of 360 ° of full-shape scopes, to caution all around, efficient doubles, and the design of hollow output shaft makes total more simple, easier manufacturing, cost are also low.

Description of drawings

Fig. 1 is the structure cross-sectional schematic of the utility model embodiment.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1, rotary warning lamp includes base 4, covers on the transparent or semitransparent lampshade 1 on the base and is arranged on the interior actuating unit 5 of base, in lampshade 1, be provided with one and be the two bowl-shape reflection shield 2 that leans against one, its underpart is the output shaft 57 grafting one of a hollow pipe 21 and extension downwards and actuating unit, and this output shaft 57 is hollow; One pillar 31 extends upward and through the hollow pipe 21 of the described reflection shield center to reflection shield, the top of pillar 31 promptly is provided with bulb 3 from base 4 through the hollow part of described output shaft 57;

Described actuating unit 5 comprises motor 56, driving wheel 55, belt 54, drive 51, driving wheel 55 links to each other with the output shaft of motor 56, belt 54 connects driving wheel 55 and drive 51 respectively, the central authorities of drive 51 have the worm screw 52 of an evagination, and the worm gear 53 that above-mentioned output shaft 57 bottoms are designed to match with it at corresponding position; During work, motor 56 drives driving wheel 55 by its rotating shaft and rotates, and drives drive 51 through belt 54 again and rotates, so the worm screw 52 of drive 51 central authorities promptly drives described worm gear 53 and then drives output shaft 57 rotations, finally causes the rotation of reflection shield 2.
