Structure of flash movable decorating lamp

The present invention relates to a structure of a flash movable decorating lamp, and especially to a structure by which a flash circuit board can be detached or attached conveniently.

In the conventional flash circuit board, if it is to have the function of sequential actions of a movable decorating lamp, other than a circuit unit comprising the original high pressure converting circuit 60 , a high voltage storage capacitor 65 , a triggering circuit 70 , a flash lamp tube 75 and a high voltage triggering coil 80 , as shown in FIG. 1, a further movable decorating lamp sequential control circuit is necessary (including a N loop movable decorating lamp sequential control circuit and movable decorating lamps 1 to N), as shown in FIG. 2 . After the aforesaid two circuits are integrated, the whole structure is bulky with a low economic efficiency in manufacturing.

Moreover, the conventional flash lamp circuit has many connecting wires in applications (such as used in application of loads) with less variations.

Therefore, there is an eager demand for a novel structure of a flash movable decorating lamp by which the defects in the prior art can be improved.

Accordingly, the primary object of the present invention is to provide a structure of a flash movable decorating lamp comprising at least one first unit and at least one second unit. Each of the first units is arranged with a high pressure converting circuit and an actuation circuit. Each second unit is installed with a movable decorating lamp flash circuit. The high pressure converting circuit and actuation circuit are connected to the movable decorating lamp flash circuit through connectors (or a bank of wires). As the present invention is used in different system with different voltage (AC or DC), it is only needed to update the high pressure converting circuit.

Another object of the present invention is to provide a structure of a flash movable decorating lamp, in which no screw is used in fixing, the flash -circuit board can be detached or attached conveniently.

A further object of the present invention is to provide a structure of a flash movable decorating lamp, wherein a serial system or a serial and parallel connection system with many variations can be formed by a plurality of first unit and a plurality of second unit.

The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

Each of the first units 1 is installed with a hollow plastic tube 11 . The hollow plastic tube 11 has substrate for a high voltage converting circuit and an actuating circuit (not shown). The plastic tube 11 has a rear opening. The inner surface thereof is screwedly connected to a stopping ring 12 and is connected to a plastic male threaded tube seat 13 by a rubber water-proof ring 10 . The rear end of the plastic male threaded tube seat 13 has a round surface which is installed with an outer thread 131 . A connector fixing seat 14 is connected to the plastic male threaded tube seat 13 . A water-proof rubber ring 15 encloses the connector fixing seat 14 . Some guide hole 141 is installed on the rear end surface of the connecting line fixing sleeve 14 .

A male threaded tube seat 17 , for assisting in positioning the plastic tube 11 , is joined to the inner surface in from the opening of the plastic tube 11 through a rubber water-proof ring 16 . A connecting line fixing sleeve 18 is installed within the male threaded tube seat 17 . The central portion of the connecting line fixing sleeve 18 is formed with a tapered clamping portion 181 . An outer thread 171 is formed on the round surface at the front end of the male threaded tube seat 17 for being threadedly connected with a female threaded tube seat 19 . A via hole 191 is formed on the female threaded tube seat 191 for being embedded by a connecting line 20 so as to be combined with the clamping portion 181 . The front end of the connecting line 20 is connected to the connector male seat 21 . The front end of the connector male sweat 21 is connected to a plastic female threaded tube seat 22 for assisting in fixing the connector male seat 21 . A plurality of inserting ends 211 are formed in the connector male seat 21 . The inserting end 211 is connected to the respective connecting line 20 . The front end of the plastic female threaded tube seat 22 has an inner surface being formed with an inner thread 221 .

Referring to FIGS. 7 to 9 , the second unit 3 is installed with a round transparent tube 31 . The transparent tube 31 is installed with a movable decorating lamp flash circuit board 30 . The rear end of the transparent tube 31 have an outer round surface connected to the plastic male threaded tube seat 32 . The round surface of the plastic male threaded tube seat 32 is installed with outer thread 321 , and a connector fixing seat 33 is connected in the plastic male threaded tube seat 32 . A water-proof rubber ring 34 covers on the connector fixing seat 33 . The rear end surface of the connector fixing seat 33 is formed with a plurality of guide holes 331 .

Further, the front opening of the transparent tube 31 has an inner surface being combined to a male threaded tube seat 36 for assisting in fixing the transparent tube 31 by the rubber water-proof ring 35 . A connecting line fixing sleeve 37 is installed in the male threaded tube seat 36 . A tapered clamping portion 371 is formed on the central portion of the connecting line fixing sleeve 37 .
