Description

Waterproof dirt-proof power pack

Technical Field

The utility model relates to an electrical equipment technical field, concretely relates to waterproof dirt-proof 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. The power pack can produce more heat in the use, in order to dispel the heat to the power pack, can set up the thermovent among the prior art usually on the casing of power pack and carry out ventilation cooling, but inside the thermovent among the prior art makes outside dust, water etc. get into the power pack easily, influences the job stabilization nature and the life-span of power pack.

SUMMERY OF THE UTILITY MODEL

A primary object of the present invention is to provide a waterproof and dustproof power supply box.

In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a waterproof dirt-proof power pack which characterized in that: the ventilating window is arranged on the shell, a plurality of grids are arranged on the ventilating window at intervals, and a ventilating opening is formed between every two adjacent grids; the upper end part of the grid at the lower side of the ventilation opening is provided with a guide plate which extends obliquely upwards, the lower end of the grid at the upper side of the ventilation opening is provided with a baffle plate which extends obliquely downwards, the guide plate and the baffle plate are both positioned in the shell, and the inner side of the ventilation window is provided with an isolation net.

Further, the ventilation windows are provided with two ventilation windows which are respectively arranged at two opposite sides of the shell.

Furthermore, the baffle is arc-shaped, and the arc-shaped circle center of the baffle is positioned below the baffle.

Furthermore, the flow guide plate comprises a first sub-plate, a second sub-plate and a third sub-plate, wherein the first sub-plate is connected with the grid and extends upwards in an inclined mode, the second sub-plate is connected with the first sub-plate and extends upwards, the third sub-plate is connected with the upper end of the second sub-plate and inclines towards the direction of the grid, and the first sub-plate is connected with the second sub-plate in a smooth transition mode.

Further, the isolation net and the shell are welded and fixed.

Compared with the prior art, the utility model has the advantages of it is following: through setting up guide plate and baffle, can block outside dust, drop of water etc to dust, drop of water etc. that receive to block can drop to the guide plate on, and then along guide plate roll-off to the casing outside, through the setting of third daughter board, can further block dust, drop of water, improve waterproof dustproof effect, through the setting of separation net, can prevent that outside mosquito etc. from getting into the power pack, ensure power pack steady operation.

Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

In the description of the present invention, it should be noted that, for the terms of orientation, such as "central", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the terms of orientation and positional relationship indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific scope of protection of the present invention.

Fig. 1 to 2 are schematic structural views of a preferred embodiment of the present application, and as shown in the figures, the waterproof and dustproof power supply box includes a housing 1, a ventilation window 2 is arranged on the housing 1, a plurality of grilles 21 are arranged on the ventilation window 2 at intervals, and a ventilation opening 22 is formed between two adjacent grilles 21; a guide plate 23 extending obliquely upwards is arranged at the end part of the upper end of the grille 21 at the lower side of the vent 22, a baffle plate 24 extending obliquely downwards is arranged at the lower end of the grille 21 at the upper side of the vent 22, the guide plate 23 and the baffle plate 24 are both positioned in the shell 1, and an isolation net 25 is arranged on the inner side of the ventilation window 2.

In the present embodiment, the ventilation windows 2 have two and are respectively disposed at opposite sides of the housing 1. Thus, the air convection in the shell 1 can be accelerated, and the heat dissipation effect is improved.

In this embodiment, the baffle 24 is disposed in an arc shape, and the center of the arc shape of the baffle 24 is located below the baffle 24. This can reduce the adhesion of dust and the like.

In this embodiment, the baffle 23 includes a first sub-plate 231 connected to the grille 21 and extending upward in an inclined manner, a second sub-plate 232 connected to the first sub-plate 231 and extending upward, and a third sub-plate 233 connected to an upper end of the second sub-plate 232 and inclined toward the grille direction, and the first sub-plate 231 and the second sub-plate 232 are connected in a smooth transition manner. Therefore, on one hand, dust and water drops are conveniently blocked, and on the other hand, the blocked dust and water drops can smoothly slide out of the shell 1.

In the present embodiment, the separation net 25 and the housing 1 are welded and fixed, and of course, screws may be used for fixing.

Of course, it should be noted that the power supply box may further include other structures, such as a mounting seat for mounting the contact pins, and the like, which are not described in detail herein since they are not within the scope of the present application.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the principles of the present invention may be applied to any other embodiment without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
