DETAILED DESCRIPTION OF THE EMBODIMENTS

As shown inFIG.1andFIG.2, in the present embodiment, the power supply box includes the box body1, and the box cover2is fitted on the box body. The box body1is internally provided with a first inner cavity30and a second inner cavity. The first inner cavity30is internally provided with a potentiometer. The adjuster3of the potentiometer passes through a cavity wall and is located in the second inner cavity. The box body1and the box cover2are fitted to form a seal. The first inner cavity30of the box body1is configured to install the potentiometer. The potentiometer can adjust parameters. The second inner cavity of the box body1can play a role in storing wires to facilitate the storage and management of the wires. In the present invention, the box body1and the box cover2are fitted to form a seal. The potentiometer is disposed in the box body1to adjust parameters. The first inner cavity30of the box body1can store the wires, which is convenient to use. With this arrangement, the power supply box has a simple structure in its entirety, is convenient to use, has the function of storing wires, and can easily adjust the output electrical parameters by the potentiometer.

In the present embodiment, the first inner cavity30and the second inner cavity are separated by the vertical partition plate4. The second inner cavity is partitioned into the first storage cavity6and the second storage cavity7through the transverse partition plate5. The two ends of the vertical partition plate4are provided with the first open slot8and the second open slot9, respectively. The first inner cavity30communicates with the first storage cavity6through the first open slot8. The first inner cavity30communicates with the second storage cavity7through the second open slot9. The adjuster3of the potentiometer passes through the vertical partition plate4and is located in the second storage cavity7. Each of the side walls of the first storage cavity6and the second storage cavity7is provided with the wire passing hole10. The inner cavity of the box body1is partitioned into a first inner cavity30and a second inner cavity by the vertical partition plate4. The second inner cavity is partitioned into the first storage cavity6and the second storage cavity7by the transverse partition plate5. In this way, there are three independent spaces, in which the first inner cavity30is configured to install the potentiometer, and the first storage cavity6and the second storage cavity7are configured to store and place wires. The installation of the potentiometer and the storage of the wires are realized by the three independent spaces. The adjuster3of the potentiometer can be adjusted in the second storage cavity7, so that it is not necessary to operate from the installing cavity, that is, the first inner cavity30. The wire passing hole10is a preprocessed hole, which is not punched through when leaving the factory. In use, the preprocessed hole is punched through as needed according to the orientation of the wire tube on site. When laying out the wiring, the wire passes through the wire passing hole10into the first storage cavity6, and then passes through the first open slot8into the installing cavity and is connected to the potentiometer. The other end of the potentiometer is connected to another wire. After that, the wire passes through the second open slot9into the second storage cavity7, and then passes out from the second storage cavity7through the wire passing hole for external connection, thereby realizing the connection between the wire and the potentiometer.

In the present embodiment, the box cover2includes the first box cover21and the second box cover22. The first box cover21is adapted to the first inner cavity30, and is snap-fitted on the first inner cavity30. The second box cover22is adapted to the first storage cavity6and the second storage cavity7, and is snap-fitted on the first storage cavity6and the second storage cavity7. The first box cover21is configured to cover the first inner cavity30. The second box cover22is configured to cover the first storage cavity6and the second storage cavity7. In this way, the three cavities can be covered separately. In use, when the parameters need to be adjusted, only the second box cover22needs to be opened, and when the potentiometer needs to be maintained, only the first box cover21needs to be opened, thereby providing a good protection effect.

In the present invention, a sealing ring is provided on each of the first open slot8and the second open slot9. The sealing ring can seal the open slot to ensure water tightness, making it waterproof and dustproof. Similarly, a sealing ring adapted to the wire can also be provided on the wire passing hole10.

In the present embodiment, the adjuster3is a knob type, slider type, or button type adjuster. The adjustment mode adopted by the adjuster3of the potentiometer includes the knob type, the slider type or the button type (0/1 type), and other forms.

In the present embodiment, each of one end of the first box cover21and one end of the second box cover22is provided with the rib11. With the rib11, the first box cover21and the second box cover22are longer than the box body1when closed, thereby providing a point of force application during opening, which is more convenient to open the box cover2.

The embodiments of the present invention have been described in terms of practical solutions, but are not intended to limit the meaning of the present invention. Modifications to the embodiments and combinations with other solutions will be apparent to those skilled in the art from the present description.
