Description

A kind of safety power switch case

Technical field

The utility model relates to a kind of electric equipment, particularly a kind of safety power switch case.

Background technology

In outdoor studies such as construction site or mine, mine, often need to use source box to provide operating current as electric equipment, but the mains switch box structure that uses is often simpler and cruder at present, its waterproof and anti-dust performance are poor, water and dust are easy to enter, cause fail safe relatively poor, the security incident that causes short circuit to cause because of the source box water inlet often occurs, to numerous workmans' life and composition of estate bigger threat.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of waterproof and dustproof performance good, easy to use, safe safety power switch case, thereby overcomes the deficiencies in the prior art.

For solving the problems of the technologies described above the technical solution of the utility model: the safety power switch case.Its formation comprises casing and chamber door, the rain visor that protrusion is arranged in the outer all around that described casing contacts with chamber door, the foam rubber sealing bar is arranged on chamber door, and this foam rubber sealing bar is corresponding with the position of rain visor, and chamber door foam rubber sealing bar after closing is pressed on the rain visor.

Above-mentioned safety power switch case, described rain visor are " L " shape, and opening surface outwardly.

Aforesaid safety power switch case is equipped with thresholding position support in the junction of chamber door and casing.

Aforesaid safety power switch case is equipped with a reinforcement on the inner surface of chamber door.

Aforesaid safety power switch case is equipped with the installation hangers in the above and below of casing.

Aforesaid safety power switch case is equipped with suspension ring above described casing.

The beneficial effects of the utility model: compared with prior art, the utlity model has excellent waterproof, dust reduction capability.The utility model pastes around chamber door and uses the foam rubber sealing bar, can prevent effectively that dust from entering in the casing, plays dustproof effect; The rain visor that protrusion is arranged all around in that casing of the present utility model contacts with chamber door can prevent that rainwater from entering in the case from top and each side of casing, plays waterproof action, and whole box body adopts hermetically sealed processes.Chamber door of the present utility model has the protecting against shock ability, at the inner surface of chamber door a reinforcement is housed, and plays the effect that increases chamber door intensity, can guarantee that chamber door stability in use is good.Chamber door of the present utility model can be fixed in an angle by after limiting bracket is installed when chamber door is opened, convenient maintenance; At casing the installation hangers is housed up and down, simultaneously the casing top adds two suspension ring, whole chest can be mounted or be lifted on any place, installs, uses more convenient, is widely used in the changing places of field work and infield such as mine, mine.
