Description

A kind of cast aluminium door binding structure that no screw is fixed

Technical field

The utility model relates to a kind of door more particularly to a kind of cast aluminium door binding structures that no screw is fixed.

Background technique

The positive facing of door-plate is the door of cast aluminium plate, is just cast aluminium door, its basic structure is three layers, and first layer is positive decorations outdoors Panel --- cast aluminium plate, hereinafter referred to as aluminium sheet；The second layer is with the liner skeleton of galvanized sheet bending and molding or other rigid skeletons；Third Layer is indoor inner veneer, it can be cast aluminium plate, is also possible to plank, is also possible to copper sheet, but at present substantially with wood Plate is most.

At present in cast aluminium door industry, the front aluminium sheet of cast aluminium door and the edge surrounding of back side plank require one step of milling Side, then beaten on this of aluminium sheet and plank milling side platform rank with screw, aluminium sheet and plank are exactly solid with this mode to screw It is scheduled on the skeleton of liner.Then in the place that screws of milling step before, for needs aesthetically, behind must use button Side (i.e. bound edge) encases the step and screw that aluminium sheet mills, while plank step and plank fixed screw are also encased, thus Nut will not be allowed to be directly exposed to outside, be otherwise difficult to see.

So, detain while main function one is step when the screw and aluminium sheet that cover fixed aluminium sheet mill, and encases The screw of fixed plank and the step on plank milling side.The second is assisting the screw of fixed aluminium sheet and plank, support is clasped for effect Aluminium sheet and backboard not fallen down.

The size of this step is very stiff because this size has a strict requirements, general length 10-20mm it Between, depth is between 2-3mm, and width cannot be less than 10mm, and otherwise later process cannot screw and aluminium sheet is fixed, and depth is not Can be too deep, because the overall thickness of aluminium sheet, having a size of 8mm, if milling too deep, screw is beaten just does not have intensity on step, because And entire aluminium sheet can not be fixed.

The aluminium sheet that usual univalve door fans four Mondays circle just needs four aluminium profiles material buckle sides that aluminium sheet and plank are encased, for side Just it screws, one or two and profile axially consistent groove is commonly designed in profile structure, in order to screw Profile button side is fixed up, etc. processes when descend into assembly process, workpeople is again with leather strap in groove, then spiral shell The nut of silk covers, and here it is the production technologies in current cast aluminium door industry.The fastness of this process structure and disappear at present Just some are not so good on the esthetic requirement of the person of expense, once because leather strap aging or falling off, when the nut exposure of screw When out, consumer just generates query and responsibility to this quality from heart.

Utility model content

The utility model is to provide a kind of cast aluminium door binding structure that no screw is fixed to solve above-mentioned deficiency.

The above-mentioned purpose of the utility model is realized by technical solution below: a kind of cast aluminium door packet that no screw is fixed The inside of side structure, including exterior trim aluminium sheet, interior trim plank, keelson frame and bound edge, the exterior trim aluminium sheet and interior trim plank is equipped with Convex falcon sliding block, the keelson frame are equipped with fourth of the twelve Earthly Branches slot sliding rail, and the exterior trim aluminium sheet and interior trim plank are mounted on by convex falcon sliding block On the fourth of the twelve Earthly Branches slot sliding rail of keelson frame；Keelson frame side is equipped with Tenon catching groove, and the bound edge is equipped with to be kissed with Tenon catching groove The button bit portion of conjunction, the bound edge are buckled in Tenon catching groove by button bit portion and are fastened on keelson frame side.This is just realized Without the purpose that screw can be connected and fixed bound edge and skeleton, this is the most important feature of the utility model.

Further, the side end face of the exterior trim aluminium sheet is equipped with aluminium sheet and mills side small stair face, and the bound edge is equipped with and aluminium Plate milling side small stair face coincide and the aluminium sheet fastened hooks position.

Further, the side end face of the interior trim plank is equipped with plank and mills side small stair face, and the bound edge is equipped with and wood Plate milling side small stair face coincide and the plank fastened hooks position.

The utility model compared with prior art the advantages of be: the bound edge of the utility model by screwing without being consolidated It is fixed, and be connected firmly, it is ensured that product quality, long product lifecycle.
