ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a structure of flickering decoration light, whose pressing cover can be pressed to touch the elastic against post to make the electric circuit plate generate electric energy and make the light flicker.
2. Description of the Related Art
Referring to
FIGS. 1 and 2
, a conventional structure of flickering decoration light includes a light base
11
and a cover
19
. The light base
11
is provided with a switching button
12
in the bottom, and an electric circuit plate
13
is provided in the groove
111
of the light base
11
. Batteries
14
are provided to generate electricity to make the light
15
flicker. An elastic article
16
is provided near the electricity-conducting portion
131
of the electric circuit plate
13
. A clamping member
17
is screwed to the bottom surface of the light base
11
by a screw
18
. Then, the cover
19
and the light base
11
are firmly combined together by means of ultrasonic welding.
The above-mentioned conventional structure of flickering decoration light can be hooked on the belt or a pocket of a user by means of the clamping member
17
. When the switching button
12
in the bottom of the light base
11
being pressed down, the elastic article
16
will be pressed to touch the electricity-conducting portion
131
of the electric circuit plate
13
and make the light
15
flicker. The switching button
12
can be pressed down again to stop the light
15
from flickering.
However, there are following drawbacks in the conventional structure of flickering decoration light
1. The parts of the structure of flickering decoration light are numerous, and the assembling process is complicated. It is not only costs much but also wastes time and labor. Because the light base and the cover are combined together by ultrasonic welding, the batteries can not be replaced when their electricity being used up, and the whole structure has to be thrown away. Therefore, it wastes money to buy another new one.
2. It is not convenient for a user to press the switching button because the light base must be turned slantly or entirely taken away from a belt or a pocket when a user intends to press the switching button.
3. It can not be widely used and can only be hooked on a belt or a pocket of a user.
SUMMARY OF THE INVENTION
Therefore, the present invention is to provide a structure of flickering decoration light that substantially obviates the drawbacks of the related conventional art.
An object of the present invention is to provide a structure of flickering decoration light whose pressing cover can be directly pressed to switch the light.
Another object of the present invention is to provide a structure of flickering decoration light whose pressing cover can be separated from the light base by slight force so as for the batteries to be replaced when the electricity being used up.
Yet another object of the present invention is to provide a structure of flickering decoration light which is more ingenious and can simplify assembling process so as to save cost, time and labor in assembling.
It is a further object of the present invention is to provide a structure of flickering decoration light which can not only be applied on a belt, a pocket, clothes of a user but also can be widely applied on furniture or machinery for decoration or warning.
Accordingly, a structure of flickering decoration light in the present invention is assembled by a light base and a pressing cover. The flickering circuit is switched by the electricity-conducting portion of an electric circuit plate provided in the interior of the pressing cover. The upper inner wall of the light base is provided with a catching flange, and the bottom circumference of the pressing cover is provided with a stopping flange so as to be movably caught in the catching flange the light base by proper force. An elastic against post is provided with a conductor in the top and is glued to connect with the electricity-conducting portion of the electric circuit plate so as to stop against between the electric circuit plate and the light base. A fastening article is provided on the outer bottom surface of the light base. The pressing cover can be pressed to switch the electric circuit to make the decoration light flicker or be extinguished.
