Abstract
The utility model provides an outdoor waterproof high-voltage metering box, which comprises a box body and a top cover plate and is characterized in that bolt holes for installing a flange fastener are machined to be upwards flanged through holes on the top cover plate and flanging height is no less than 5mm; and corresponding bolt holes on the flange fastener are machined to be inwards concave holes, the inner diameter of each inwards concave hole is larger than the outer diameter of each flanged hole on the top cover plate, the inwards concave holes are in clearance fit with the flanged holes, and the flange fastener is fastened corresponding to the flanged holes on the top cover plate and is tightly fixed from the internal side of the box body by using bolts. The outdoor waterproof high-voltage metering box has the advantages that the structure is simple and effective, part machining difficulties are low, the metering box is convenient to install and a waterproof function is realized because an upper fastening part and a lower fastening part are assembled by using a concave-and-convex matching method.
Description
Technical field
The utility model relates to a kind of structure of High-voltage measuring box, especially the waterproof construction of the lamina tecti upper flange fastener mounting hole of waterproof outdoor high-voltage batch meter.
Background technology
At present, outdoor High-voltage measuring box use amount is more and more, and conventional outdoor high-voltage batch meter turnover line all is arranged on the lamina tecti of case, fixes with the flange fastener, and the flange fastener adds waterproof washer with batch meter lamina tecti employing bolt and is connected.But there is problem of aging in waterproof washer, brings potential safety hazard can for the High-voltage measuring box of long-time running.
The utility model content
The purpose of this utility model is to provide a kind of waterproof outdoor high-voltage batch meter, solves the waterproof problem in mounting flange fastening bolt hole on the batch meter lamina tecti from structure, removes a hidden danger, and improves the security performance and the serviceable life of outdoor measurement equipment.
The technical solution of the utility model is: a kind of waterproof outdoor high-voltage batch meter, comprise casing, lamina tecti, wherein, the bolt hole of mounting flange fastener is to the upper overturning hole on the described lamina tecti, bolt hole on the flange fastener is an inward recess, and the internal diameter of inward recess is bigger than the external diameter in lamina tecti flange hole.
The flange height in described flange hole is not less than 5mm.
She Zhi You Gui rubber gasket in the inward recess on the described flange fastener.
It is simple and reliable for structure that the utility model adopts, and fastens up and down to adopt concavo-convex fit system to realize water-proof function between the part.
Description of drawings
Fig. 1 is the utility model body structure synoptic diagram;
Fig. 2 is the utility model flange fastener structures synoptic diagram;
Among the figure: 1-casing, 2-lamina tecti, the flange hole on the 3-lamina tecti, 4-flange fastener, the inward recess on the 5-flange fastener.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As Fig. 1 and Fig. 2, the waterproof outdoor high-voltage batch meter that the utility model provides comprises casing 1, and lamina tecti 2 the bolt hole of mounting flange fastener, is processed into to upper overturning through hole 3 on lamina tecti 2, and the flange height is not less than 5mm; Bolt hole on the corresponding flange fastener 4, be processed into inward recess 5, and the internal diameter of inward recess 5 is bigger than the external diameter in lamina tecti upper overturning hole 3, the two clearance fit, with flange fastener 4 and lamina tecti 2 upper overturning holes 3 corresponding fastenings, carry out fastening from box inside with bolt.If Jia Zhuan Gui rubber gasket in flange fastener inward recess 5, water resistance is better.
Certainly, those skilled in the art also can be altered to through hole to top cover upper overturning hole 3, carry out self-clinching nut man-hour in advance adding, or be processed into the flange threaded hole, when subsequent production is installed, with self-clinching nut or the corresponding fastening of flange threaded hole on flange fastener 4 and the lamina tecti, carry out fastening with bolt then.
What the utility model adopted is simple in structure effective, and the part processing difficulty is little, easy for installation, fastens up and down to adopt concavo-convex fit system to realize water-proof function, the security performance and the serviceable life of having improved outdoor measurement equipment between the part.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
