The box that has electrical components including internally mounted, the box up end is equipped with a plurality of screw holes, the box upper end is equipped with the electrical apparatus lid, the lower extreme of electrical apparatus lid is equipped with the step, the lateral wall of step is located the box inboard, the lower extreme periphery of electrical apparatus lid is equipped with a plurality of screw counter sinks, the screw counter sink runs through end face of bench, it is connected with the screw hole of box up end to be equipped with the screw in the screw counter sink, a water drainage tank has been seted up on the lateral wall of screw counter sink, water drainage tank's orientation is outside, water drainage tank is used for row ponding, be equipped with the sealing washer between the lower terminal surface of electrical apparatus lid and the up end of box. The utility model discloses the internal damage electrical part of screw counter sink longitudinal stream into boxes of effectively avoiding ponding to cover along electrical apparatus has improved the life of electrical part, add the sealing washer, improved the leakproofness to box inside electrical part greatly, the normal use life -span of further having guaranteed the electrical part.
Description
Technical field
The utility model relates to the waterproof construction that a kind of electrical equipment lid is connected with casing.
Background technology
At present, in the outside of known electric actuator, time electrical equipment lid and casing are by screw fastening, screw is not be directly exposed to outside, prevents external force from colliding and causes screw loosening.General is all cover at electrical equipment the counter sink arranging mounting screw, but when rainwater, humidity are comparatively large or other are intake, ponding is had in the counter sink being provided with screw, if other sealing surfaces strictly do not seal or seal is aging, ponding will penetrate into faying face between electrical equipment lid and casing along counter sink, then ponding is slowly penetrating into electric actuator inside, because the electric device self of electric actuator inside does not possess water resistance, thus the useful life of electric actuator internal electrical device can be greatly reduced.In the industries such as oil, chemical industry, electric power, metallurgy, papermaking, water treatment, because construction environment is more severe, the factors such as the large or rain penetration of ambient air humidity, all will be able to affect the useful life of electric actuator internal electrical device, therefore waterproof sealing performance requires higher.
Utility model content
For above-mentioned defect, it is simple that the purpose of this utility model is to provide a kind of structure, can prevent there is ponding in screw counter sink, effectively ensure the useful life of casing internal electrical device.
The technical scheme that the utility model adopts for this reason is:
Comprise the casing that inside is provided with electric elements, described casing upper surface is provided with some screwed holes, described casing upper end is provided with electrical equipment lid, the lower end of described electrical equipment lid is provided with step, the sidewall of described step is positioned at box inside, the lower end peripheral of described electrical equipment lid is provided with some screw counter sinks, described screw counter sink runs through step end face, be provided with screw in described screw counter sink to be connected with the screwed hole of casing upper surface, the sidewall of described screw counter sink offers a rhone, described rhone towards outwards, described rhone is used for arranging ponding, sealing ring is provided with between the lower surface of described electrical equipment lid and the upper surface of casing.
Further, inside the upper surface of described casing, be provided with a groove, in described groove, be provided with sealing ring, the upper surface of described sealing ring and the lower surface of electrical equipment lid inconsistent, inner side end and the mesa sidewall of described sealing ring are inconsistent.
Further, the width of described rhone must not be greater than the diameter of screw, and the bottom of described rhone must not higher than the mounting plane of screw.
The utility model has the advantages that:
The utility model structure is simple, by offering rhone on the sidewall of screw counter sink, when producing ponding in screw counter sink, ponding will flow out from rhone, the screw counter sink longitudinal stream effectively avoiding ponding to cover along electrical equipment enters in casing to damage electric device, improves the useful life of electric device; By setting up sealing ring at the composition surface place of electrical equipment lid and casing, substantially increasing the sealing to box house electric device, further ensuring the normal service life of electric device.
Accompanying drawing explanation
Fig. 1, Fig. 2 are structural representations of the present utility model.
In figure, 1 be casing, 2 are screwed holes, 3 are electrical equipment lids, 4 are screw counter sinks, 5 are screws, 6 are rhones, 7 is sealing rings.
Embodiment
The waterproof construction that a kind of electrical equipment lid is connected with casing, comprise the casing 1 that inside is provided with electric elements, described casing 1 upper surface is provided with some screwed holes 2, described casing 1 upper end is provided with electrical equipment lid 3, the lower end of described electrical equipment lid 3 is provided with step, the sidewall of described step is positioned at inside casing 1, the lower end peripheral of described electrical equipment lid 3 is provided with some screw counter sinks 4, described screw counter sink 4 runs through step end face, be provided with screw 5 in described screw counter sink 4 to be connected with the screwed hole 2 of casing 1 upper surface, the sidewall of described screw counter sink 4 offers a rhone 6, described rhone 6 towards outwards, described rhone 6 row of being used for ponding, sealing ring 7 is provided with between the lower surface of described electrical equipment lid 3 and the upper surface of casing 1.
Further, be provided with a groove inside the upper surface of described casing 1, in described groove, be provided with sealing ring 7, the upper surface of described sealing ring 7 and the lower surface of electrical equipment lid 3 inconsistent, inner side end and the mesa sidewall of described sealing ring 7 are inconsistent.
Further, the width of described rhone 6 must not be greater than the diameter of screw 5, and the bottom of described rhone 6 must not higher than the mounting plane of screw 5.
