Description

Novel power supply box

Technical Field

The utility model relates to an electrical equipment technical field, concretely relates to novel power pack.

Background

The power box is usually connected between the electric equipment and the commercial power to convert the commercial power voltage into a voltage meeting the requirement of the electric equipment. However, the output socket of the existing power box is usually exposed outside, after long-time use, external water, dust and the like are easy to enter and fall on the contact pin through the socket, and meanwhile, the external dust and the like can enter the power box through gaps around the switch button, so that the working stability and safety of the power box are affected.

SUMMERY OF THE UTILITY MODEL

A primary object of the present invention is to provide a novel power pack with waterproof and dustproof functions.

In order to achieve the above purpose, the utility model adopts the technical scheme that: a novel power pack, its characterized in that: the novel multifunctional switch cabinet comprises a housin, be provided with the first opening that is used for setting up output socket on the casing and the second opening that is used for setting up shift knob, first opening is provided with first annular boss all around, be provided with on the casing can with first annular boss up end contact in order to carry out the apron that the lid closed to first opening, the second opening is provided with second annular boss all around, second annular boss up end is connected with elastic expansion sleeve, elastic expansion sleeve upper end upside is connected with button face lid and the downside is connected with the ejector pin that can reciprocate in step with button face lid.

Furthermore, one side of the cover plate is hinged with the upper surface of the shell, and the other side of the cover plate is clamped with the upper surface of the shell.

Furthermore, the cover plate is provided with a containing groove which has the diameter equivalent to that of the first annular boss and can be used for the first annular boss to stretch into, and an elastic gasket is arranged in the containing groove.

Furthermore, the diameter of the upper end of the elastic telescopic sleeve is smaller than that of the lower end of the elastic telescopic sleeve and is arranged in a conical shape.

Compared with the prior art, the utility model has the advantages of it is following: through setting up apron and elastic expansion sleeve, can prevent inside outside water, dust etc. get into the power pack, can prevent outside water from flowing into the power pack inside from the casing upper surface through setting up first annular boss and second annular boss simultaneously to make the power pack have fine waterproof dustproof performance.
