Description
Technical field
The present invention relates to stainless steel composite material ground connection and draw the compression bonding apparatus of reaching the standard grade.
Background technology
China's Granted publication number is that the earth rod that CN202189901U, name are called in the utility model patent of " the stainless steel Baogang structure of electric power grounding grid earth rod " namely is to draw to reach the standard grade, and drawing reaches the standard grade is made up of steel plug and the stainless steel wrap of closely wrapping up its outer peripheral face.At present stainless steel compound draw to reach the standard grade apply gradually.The compound end face of reaching the standard grade that draws of stainless steel exposes, and corrosion phenomenon takes place easily, causes potential safety hazard.China's Granted publication number is that the utility model patent of CN202172131U discloses a kind of conductive connection plates of reaching the standard grade of drawing, conductive connection plates comprises binding and draws the tube connector of reaching the standard grade, binding namely is terminal, binding is sheet, have breach on the upper surface of binding, draw the tube connector of reaching the standard grade and insert in the breach of binding, the binding of breach both sides is fixed by electric welding with the diameter two ends of drawing the tube connector of reaching the standard grade respectively, the weld zone has four.
Summary of the invention
The stainless steel composite material ground connection that the objective of the invention is to propose a kind of novelty is drawn the compression bonding apparatus of reaching the standard grade, and this compression bonding apparatus can prevent from drawing the end face corrosion and can further improve and draw the firmness of reaching the standard grade and being connected with binding post of reaching the standard grade.
For achieving the above object, the present invention takes following technical scheme: the stainless steel composite material ground connection that the present invention proposes is drawn the compression bonding apparatus of reaching the standard grade, have to draw and reach the standard grade and binding post, drawing reaches the standard grade is made up of steel plug and the stainless steel wrap of closely wrapping up on its outer peripheral face, described binding post top is the steel rectangular slab, the bottom is the steel pipe, the bottom surface of steel pipe is provided with centre bore, on binding post utilizes the centre bore of steel pipe to be enclosed within to draw and reaches the standard grade, between reaching the standard grade, the steel pipe of binding post and drawing is provided with the edge cover, be distributed with hardness greater than drawing the interior spine of reaching the standard grade on the inwall of edge cover, be distributed with hardness greater than the outer spine of binding post on the outer surface of edge cover, externally under the tool holder, the steel pipe of binding post and the deformation of edge cover, in, outer pointed tooth penetrate into respectively draw in the steel plug of reaching the standard grade and cylindrical center's hole hole wall of binding post in.
Described edge cover is combined into by at least two arc-like sheets.
Inwardly shrink in the steel pipe stage casing of described binding post, forms 1 to 2 joint small diameter part position, and the small diameter part position is the tool holder district.
The steel rectangular slab of described binding post is provided with two connecting holes.
The present invention has following good effect: 1, the present invention take to be arranged on draw reach the standard grade and binding post between be provided with edge cover, cylinder by the external tools pair of wire connection terminals clamps, the inside and outside spine of edge cover penetrates into respectively in the cylindrical center's hole hole wall that draws the steel plug of reaching the standard grade and binding post, improved greatly draw reach the standard grade and binding post between the firmness that connects, and having increased bonded area between them, passage section is corresponding increase also.2, on binding post of the present invention utilizes centre bore to be enclosed within to draw and reaches the standard grade, draw the end face of reaching the standard grade and hidden by binding post, so can prevent from drawing the end face of reaching the standard grade because of the exposed corrosion that is subjected to environment.3, binding post no longer needs to carry out the surface anticorrosion processing.4, owing to do not need to weld at the construction field (site), eliminate the potential safety hazard that exists because of welding.
