Description

Power control box for LED string lights

Technical field

The utility model relates to an LED light string, in particular to a power control box used for providing electric energy or signals for the LED light string.

Background technique

Nowadays, LED string lights are popular because they not only beautify the night view of cities and villages, but also have the advantages of low power consumption and low price. As the amount of LED string lights is large, the power control box (also called battery Boxes) are also in great demand. The power control box is equipped with a circuit board, a chamber for installing batteries (usually at least two batteries are installed) and related switch buttons.

Most of the power control boxes in the prior art are relatively simple rectangular boxes made of transparent plastic materials. They include a box cover and a box body. The battery is installed in the box body. The box cover adopts a sliding cover structure and can be fastened to the box. Physically, the power control box with this structure has the following shortcomings: there is no sealing structure between the box cover and the box body, so it has poor water resistance and is easily damaged. There is also a power control box. A sealing structure is provided between the box cover and the box body, but there are at least two buckle plates arranged between the box cover and the box body, and the box cover and the back of the box body adopt a hinge connection structure There are two shortcomings: each time the box cover is opened or closed, because there are two gussets, the operation needs to be performed twice, and after opening one of the gussets, when the other gusset is opened, The opening force generated by the box cover relative to the box body is relatively laborious. At the same time, the rotating shafts in the two separate hinge connection structures on the back of the box cover and the box body will also be unevenly stressed and deformed over a long period of time. In addition, the appearance and visual sense of the power control box in the prior art are relatively monotonous and flat, and the aesthetic feeling is not good.

technical problem

The technical problem to be solved by the utility model is to provide a power control box for the led light string with a beautiful appearance, a clean shell with a clean aesthetic feeling and a good three-dimensional feeling, and can reach the waterproof and dustproof grade of IP65.

A color brightness button that can control the luminous color and brightness of the LED light string is arranged at another corner adjacent to the flashing button on the top surface of the flip cover.

A sealing washer is arranged between the flip cover and the base, and the sealing washer is embedded in a sealing groove arranged on the top edge of the base.

The hinge structure is composed of three hinge shafts evenly arranged on the back of the flip cover and three hinge seats arranged on the back of the base, wherein one hinge shaft corresponds to one hinge seat, and each hinge shaft is installed on the corresponding one by crimping. On the hinged seat.

The buckle connection structure is composed of a left shaft groove, a right shaft groove, a gusset plate, a return spring, and a clamp block. The left shaft groove and the right shaft groove are arranged on both sides of the front of the flip cover, and the top two sides of the buckle plate are provided with left pivots. The shaft and the right pivot, the gusset plate makes the left pivot and the right pivot fit into the left and right shaft grooves respectively through the return spring. The clamping block is set on the front of the base. Flip the gusset down to make the gusset and the clamping block. Connect them together and seal the flip to the base.

The width of the buckle plate is 1/3-1/2 of the width of the flip cover, and two buckle holes are provided on the buckle plate. The block and the right clamping block are respectively tightly connected with a male and female buckle hole on the buckle plate.

The width of the buckle plate is 1/3-1/2 of the width of the flip cover, the width of the clip is slightly smaller than the width of the buckle plate, and a magnetic connection structure is provided between the inner side of the buckle plate and the clip block.

The shell is made of plastic material.

The length×width×thickness of the outer contour of the shell is (7cm-15cm)×(3cm-5cm)×(1cm-5cm).

Each of the four corners of the top surface of the flip cover is provided with a pseudo screw which can enhance the strong visual effect of the power control box.

Beneficial effect

Compared with the prior art, the utility model adopts a shell with a smooth and flat top surface, a buckle connection structure adopting a single-plate buckle block and a more balanced hinge structure, so that the shape of the power control box is Beautiful atmosphere, so that when the flip cover is opened or closed, it is less laborious, the flip cover is turned smoothly and smoothly, and the flip cover and the base will not be twisted and deformed after long-term use. An annular sealing gasket is used between the flip cover and the base, so that the waterproof and dustproof level of the flip cover and the base can reach IP65. The power control box of the utility model is provided with reinforcing ribs on the inner surface of the flip cover and the base to increase the strength of the shell, so that the impact resistance of the shell is greatly increased, which is beneficial to avoid damage caused by collision during long-distance transportation.
