Abstract

An outdoor power box body comprises a box body and a box cover, wherein a rectangle opening is formed on the front end surface of the box body, the box cover is hinged with the box body and can seal the rectangle opening, and the box cover is a rectangle faceplate; four edges of the rectangle faceplate are bent inwards to form a bending edge, four edges nearby the rectangle opening on the front end surface of the box body are bent inwards to form a step; the step includes a side surface perpendicular to the front end surface of the box body and a bottom surface perpendicular to the side surface, inwards-recessed drain grooves are molded on the outer wall of the bending edge and the side surface of the step; in a rainy day, rainwater permeating through the space between the bending edge and the side surface of the step is cut off by the drain grooves and discharged through the drain grooves, therefore, the fact that no rainwater can permeate into the box body is ensured, electrical elements in the box body are free from damp, and the service life of the electrical elements is ensured; and moreover, the structure simply adds the drain grooves, and the drain grooves can perform an integrated punching in a stamping process of the box body and the body cover, therefore, the structure is simple and the manufacturing cost is low.

Description

A kind of outdoor use power supply box casing

Technical field:

The utility model relates to a kind of power supply box, especially a kind of outdoor use power supply box casing.

Background technology:

Power supply box of the prior art, comprise that front end face is provided with the casing of rectangular aperture and hinged and can seal the case lid of this rectangular aperture with casing, case lid is a rectangular panel, these rectangular panel four limits all bend inwards and form a bending edges, lean on place, rectangular aperture four limits all to bend inwards on the casing front end face and form a step, this step comprise a side vertical with the casing front end face and with the bottom surface of this lateral vertical, in the use, case lid replaces rectangular aperture on the closed box by bending edges is terminal with the step bottom surface, but, such power box does not have waterproof construction, when outdoor application, if meet the rainy day, rainwater is easy to from the case lid the slit between the bending edges and step and infiltrates in the casing, electric elements in the casing are made moist, thereby accelerated the damage of electric elements, shortened the useful life of electric elements.

The utility model content:

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and anti-rainwater of a kind of energy and outdoor use power supply box casing simple in structure, cheap for manufacturing cost are provided.

A kind of outdoor use power supply box casing that provides according to the utility model, comprise that front end face is provided with the casing of rectangular aperture and hinged and can seal the case lid of this rectangular aperture with casing, described case lid is a rectangular panel, these rectangular panel four limits all bend inwards and form a bending edges, lean on place, rectangular aperture four limits all to bend inwards on the described casing front end face and form a step, this step comprise a side vertical with the casing front end face and with the bottom surface of this lateral vertical, the bending edges end can be replaced with this bottom surface on the described case lid, with the sealing rectangular aperture, all form inwardly recessed rhone on the described bending edges outer wall and on the side of step.

A kind of outdoor use power supply box casing according to the utility model provides has following advantage with respect to prior art:

In this structure, all forming inwardly recessed rhone on the bending edges outer wall of case lid and on the side of casing step, when running into rainwater weather, the rainwater that infiltrates between bending edges and the step side is intercepted by rhone, and drain through rhone, guarantee that rainwater can not penetrate in the casing, make the electric elements in the casing avoid making moist, guaranteed the useful life of electric elements; Simultaneously, this structure has only increased rhone, and rhone can one be gone out in to the punch process of casing, case lid, thereby it is simple in structure and cheap for manufacturing cost.

Description of drawings:

Introduce the utility model in detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the sectional structure schematic diagram of A-A among Fig. 1;

Fig. 3 is the structure for amplifying schematic diagram of I among Fig. 2.

Embodiment:

With reference to Fig. 1, Fig. 2, the described a kind of outdoor use power supply box casing of Fig. 3, comprise that front end face is provided with the casing 1 of rectangular aperture 11 and hinged and can seal the case lid 2 of this rectangular aperture 11 with casing 1, electric elements are installed in the casing 1, case lid 2 is a rectangular panel, these rectangular panel four limits all bend inwards and form a bending edges 21, lean on place, rectangular aperture 11 4 limits all to bend inwards on casing 1 front end face and form a step 3, this step 3 comprises side 31 vertical with casing 1 front end face and the bottom surface 32 vertical with this side 31, bending edges 21 ends can be replaced with this bottom surface 32 on the case lid 2, with sealing rectangular aperture 11, all form inwardly recessed rhone 4 on bending edges 21 outer walls and on the side 31 of step 3, above-mentioned bending edges 21, step 3 and rhone 4 all can be made by Sheet Metal Forming Technology, when running into rainwater weather, the rainwater that infiltrates between bending edges 21 and the step upper side 31 is intercepted by rhone 4, and drain through rhone 4, guarantee that rainwater can not penetrate in the casing 1, in addition, lower end at casing 1 and case lid 2 also should be provided with the delivery port that communicates with rhone 4, so that rainwater is discharged to ground.
