Description

The base of modular electrical casing
Technical field
The present invention relates to the base of electrical box, is specifically the base of a kind of knockdown cable branch box or electrical branch box body.
Background technology
The base of the electrical box of prior art, it is generally the shaping plastic construction of the shaping glass fibre reinforced plastic structure of the split of two halves formula or integral die or integral molded plastic, and no matter be two halves formula or integral type, all there is shape and complex structure, the series of problems such as die sinking cost is high, mold pressing scrappage is high, rate of finished products is low.And integral type, once damage a part, has been scrapped completely with regard to entirety.And also there is split type base in prior art, but the requirement of strength of the connector of split type base various piece is very high, panel beating connector must be adopted, as all parts is connected into overall base by the two logical panel beating connectors at right angle or the threeway sheet metal component in XYZ tri-directions, like this, certainly will increase the holistic cost of base, and the installation process of panel beating connector is very loaded down with trivial details, wastes time and energy; And Split type base is also made up of the parts of each different structure, each parts still need to open one set of die separately, and its die sinking cost is still very high.
Summary of the invention
The technical problem to be solved in the present invention is, provides the base of simple, the assembled convenience of a kind of structure, die sinking cost is low, intensity is good modular electrical casing.
Technical solution of the present invention is, provides a kind of base with the modular electrical casing of following structure,
It comprises four identical side connecting plates of structure;
Each side connecting plate comprises a main panel and is fixed on the first side flanging of main panel head end, first side flanging is provided with the spacing raised line of evagination, first side flanging is provided with the first horizontal screw slots, the main panel back side is provided with the spacing slot and mount pad that supply spacing raised line grafting, and mount pad is provided with screwed hole;
Four side connecting plates head and the tail connect and compose closed square frame, in the spacing slot that the spacing raised line of each side connecting plate head end is inserted into a side connecting plate tail side and each side connecting plate head end through first screw slots through this side connecting plate and the screw screwed in the screwed hole of a upper side connecting plate tail side and a upper side connecting plate tail side fix.
After adopting above structure, the base of modular electrical casing of the present invention compared with prior art, has the following advantages:
Above-mentioned base is put together by structure and the identical four pieces of connecting lateral plates of shape, and the structure of each connecting lateral plate and shape matching simple, during die sinking, only need output the mould of a set of connecting lateral plate, the complex-shaped mould of unsplit bedplate must be outputed relative to prior art, or output many molds of multiple different parts, base die sinking cost of the present invention obviously reduces; And, the assembled process of this base is very convenient, only need also with a screw, both to be screwed in the spacing slot of the upper connecting lateral plate of spacing raised line insertion of each connecting lateral plate head end, in other words four screws are altogether relied on just can to complete the assembled of whole base and without the need to using any panel beating connector, eliminate the cost of panel beating connector, and assembled process is convenient, fast, laborsaving; Moreover the syndeton of this base is reasonable in design, first to be located by the male and female grafting between spacing raised line and spacing slot, then by screwing in the screw fastening of mount pad through the first screw slots, bonding strength is high, meet designing requirement, ensure that the total bearing capacity of base.
As improvement, the tail end of the main panel of each side connecting plate is fixed with tail side flanging, side flanging is fixed with on the upside of main panel, be fixed with lower flange on the downside of main panel, first side flanging, upper side flanging, tail side flanging are connected successively with lower flange, the design of above-mentioned four flange, both ensured that strengthening bottom made base lay steadily with the contact area on ground, reasonably enhance bulk strength again, and also effectively reduce the integral thickness of side connecting plate under the prerequisite of proof strength, save material.
As improving again, the upper side flanging of each side connecting plate is provided with multiple second screw slots, each second screw slots both sides are respectively provided with a triangular stall board, each triangular stall board is fixed with upper side flanging and main panel respectively, like this, screw is screwed in the screwed hole of the electrical box on top through the second screw slots, under the prerequisite without the need to separately increasing sheet metal connector, just meet the problem that base is connected with the electrical box on top, and Appropriate application is to the upper side flanging existed, and the existence of the triangular stall board of each second screw slots both sides effectively improves the intensity at screw fastening place.
As preferably, the back side of the main panel of each side connecting plate be provided with from upper side flanging extend to mount pad upper dowel, extend to the lower dowel of mount pad from lower flange and extend to the horizontal dowel of mount pad from tail side flanging, tail side flanging, upper side flanging, upper dowel, mount pad and horizontal dowel form a spacing slot of top, and tail side flanging, lower flange, lower dowel, mount pad and horizontal dowel form a spacing slot of below; Spacing raised line on the first side flanging of each side connecting plate is upper and lower two, like this, the bulk strength of side connecting plate is increased with three dowels newly increased, and form under spacing slot meets the prerequisite of grafting needs at more strength, also effectively reduce the integral thickness of whole side connecting plate, save material, reduce further cost.
